Abstract

The present invention relates to a drilling hole bored concrete pile machine and the relative technical field. The purpose of the present invention is to design with a novel idea, and to integrate the performances of the existing pile driver, thus being relatively different from the traditional pile driver. The design of the complete machine is novel, though the complete machine is composed of a plurality of mechanisms, the construction of each mechanism is relatively simple, partial part is formed by welding the section material cut down. The manufacturing cost is inexpensive. The pile driver combines the drilling claw and the traditional direct circulation driller and the reverse circulation driller into a whole, thus being capable of drilling, clawing and rushing, and being divided in detail, more than 30 drilling methods are obtained (including environmental friendly and non environmental friendly). No matter how the stratum is complicated, hard or soft, the present invention even can deal with the shifting sand stratum, and as for the stratum, the present invention is almighty. The pile driver with different calibers can be designed according to the needs, the smallest is about diameter of 800 to diameter of 900, and the largest can be larger than the diameter of 3000 mm. By drilling with the direct circulation method, the depth can be over 200 m; and by drilling with the reverse circulation method, the depth is about100 m. Except for being suitable for construction in land, the present invention is more suitable for operation at sea. At present the pile driver is not available in domestic and abroad.

Description

Integrated multifunctional hole-drilling pile-filling machine

One, the stake machine class in the construction of basic fields such as building and bridge is various at present for technical field, but the function of their overwhelming majority is not very complete.If buy multiple stake machine simultaneously, then very uneconomical economically.The objective of the invention is to want the function of all hole-drilling pile-filling machines is at present combined as far as possible, reach a tractor serves several purposes.For various bad grounds, no matter be hard, soft or even drift sand formation or sposh, it can both creep into.Be not only applicable to land operation, also be applicable to operation at sea.

Two, background technology is people from Rong County, Guangxi, and Central-South China Institute of Mining and Metallurgy's graduation in 1964 is worked in geologic prospecting party afterwards always.Geological Engineering technology senior engineer.Discontented 55 years old of the end of the year 1992 went home with regard to retirement, and the back helps the individual to do geological mapping work, mainly is to do foundation engineering and write report.But good times don't last long, done with regard to no work less than one-year age.The free of always being in later on feels very boring, because of I from having deep love for machinery for a short time, during the university also layer learned some mechanical knowledges.Simultaneously, household economy is relatively more difficult again, and my first heel boss goes to open a mine, and learns the geographical date again, but does not all have successfully.So just expect doing some gizmos, if luckily perhaps can bring some benefits to life.Since then, everyday the be in data of browsing or do design.Through effort in a few years, I successively design five patents.And selected wherein one in August, 2000---the application of big gun formula entertainment body-building device patent.At that time with the application of leaf intelligence (former name) name, patent No. ZL00230732.4.Through twists and turns in a few years, handed over 4 years annual fees, not only the patented technology transfer is not gone out, and has been deceived some money by the cheat in the society on the contrary, implements to be a problem if control oneself yet, and household economy difficulty and household oppose.So I have not handed over the 5th year annual fee.But I am nonlose heart, have expected the second outlet again, feel to do Foundation Design and make money very much, but advanced instrument must be arranged.Tentatively understand according to me, present stake machine technology is still more single, and comprehensively the stake machine is all right if there is one.Past, I was very familiar to the core drilling technology when working in geologic prospecting party, knew which type of technology which type of stratum adopt go to solve.I managed two bench drill machines once, mainly crept on loose stratum of easily collapsing, and drill footage per month often surpasses km as a result, and a year drilling depth is crossed myriametre.And others' rig drill footage per month 400-500 rice of pipe is just good.Though I did not learn engineering geology, the stake machine technology is understood inadequately, I also often go to see that others drives piles, feel also so-so.In order to realize purpose, I call in " modern basic engineering construction " textbook to geologic prospecting party, be the end of the eighties Changchun Geology Colledge compile, taken in the stake machine technology should be newer.I have almost spent the time more than 2 years to go study research, wherein the basic engineering construction environment division am read again and again, till getting a thorough understanding of.I liquidate grab the complete set of pipe pile machine and Japan many drill bits of RRC type diving pile driver interested.But feel also to have their limitation, contain gravel or hard slightly any stratum just can not be crept into.After study, I roughly understand the performance (I am ignorant of may to also have more advanced stake machine certainly in recent years) of existing stake machine, have increased many knowledge.But here I do not have necessity of mimicker, and I should breaking conventional conception, design a kind of novel stake machine---integrated multifunctional hole-drilling pile-filling machine according to my thinking.Must inherit forefathers' drilling technology to some, I have also done bigger modification as boring enlarging aiguille and drill hammer.

Three, summary of the invention 1, dash the stake machine that bores of grabbing (Fig. 1-Fig. 5).Existing at present dashing grabbed all casing drill, do not grab rig (rotary drilling rig and spiral drilling machine sheerly bore, and can not grab) but also bore.So the purpose here is to want to design a stake machine that can bore, can grab and can dash.Outside creep on the most complicated stratum of deconditioning, also suitable operation at sea.It is that the special shape of diving pile driver and the RRC type rig of Japan have similarity, promptly need not the drilling rod transfer torque, can play direct circulation, reverse circulation drilling.But it is structurally different fully.The characteristics of this machine are to utilize the mobile wing drill bit to do continuous reaming to creep into, and with special device inside and outside sleeve pipe are followed under the drill bit at the bottom of the hand-hole, and it is exactly a grab bucket that fin draws in, is a drill bit when opening, and can pulls from inner sleeve.Whole stake machine is not rotated with bottom rotation two large divisions by top to be formed.

The top non-rotating structure is by closed chamber, top axle bearing apparatus, water pipe twist preventing apparatus, lifting appliance, cable, lower bearing equipment and increase the weight of chamber etc. and form.Closed chamber is rolled by steel plate and is welded, and upper and lower adding welded a clamping ring, and seals middle cushioning with circular steel plate.Indoor two miniature motors and the travelling gear of being equipped with.Do not establish gear, mainly utilize the high-tech product on the face of land---variable-frequency governor is realized the speed change of motor, and is much more flexible like this, and different rock-layers can be crept into different rotating speeds.The closed chamber outer wall is symmetrically welded with two guiding side's bars, and a machine is moved up and down along the inner sleeve gathering sill.A radial and axial bearing is arranged in the top axle bearing apparatus, can hang the total weight of a machine, utilize sealing ring and bearing that the central tube of rotation and the drainage joint that does not rotate are separated simultaneously.Because the stake machine can not rotate in inner sleeve, and the water pipe hoist engine on well head top is being rolled up, let slip in the journey, its can produce a kind of torsion to water pipe, in order to address this problem, so designed the water pipe twist preventing apparatus here.It is fixed on the bigger seamless pipe, also is to utilize sealing ring and bearing, and the drainage joint of rotation and fixing twist preventing apparatus are responsible for separately.Lifting appliance comprises two bale handle posts and a bale handle.Elevator has two kinds, and a kind of is to creep into usefulness usually, and two bearings are housed, and can arbitrarily rotate.Another kind is specialized in percussion drilling usefulness, no bearing.But spring is housed, drill bit is rotated.Cable is sealed by a plurality of sealing rings.A radial and axial bearing is also arranged in the lower bearing device, play sealing, location and pressure-bearing effect.Increase the weight of chamber device, be welded into a short cylinder after rolling by the 10mm steel plate, the upper and lower clamping ring of weldering that adds, its symmetry has eight holes (top is screwed hole).Both sides are symmetrically welded guiding side's bar equally, but corresponding with the square bar of top seal chamber.Top and closed chamber join, and the bottom adds a circular steel plate, bottom center's welding step.The indoor weight of laying as required.

The bottom rotating part by the flap-like drill bit, hang cylinder, linkage, cross recess and fin drill bit are opened locking mechanism etc. down.

The flap-like drill bit has four, and every is cut into different trapezoidally by three 10mm steel plates, weld just to become after bending again.The bottom edge of a knife is a quick-wear part, for ease of welding alloy sheet or surfacing alloyed powder, so processing in addition connects with bolt.In the drill bit back side, the bottom is welded with three wedge-likes wear-resisting (geology with) steel disc, all has horizontal tank (each sheet position is different) by certain distance, two on middle part and right side respectively stud with alloy sheet or surfacing alloyed powder.Edge of a knife bottom does not need to weld steel disc, directly processes from skin, and the bottom also studs with alloy sheet or surfacing alloyed powder.The outstanding fin of the edge of a knife of right side wedge-like steel disc outside, inclined-plane and hole wall are tangent, are mainly used in the cutting rock stratum.Left side wedge-like steel disc is not outstanding, and consistent with flap edges, its inclined-plane and fin bit diameter are tangent.Do not need the welding-on alloy sheet at this, but answer some alloyed powders of surfacing.Its main effect is to make the fin drill bit when counter rotation, can produce a kind of interior to the pressure that shrinks.But it also wants rock cutting at the same time, thus should be within it the alloy sheet of layer edge or center line middle and lower part welding-on some.Sometimes in the heavy caliber water well drilling, need change outer tube into pipe of cement, then thickness (being diameter) increases more.In order to address this problem, in the horizontal tank of a wedge-like steel disc in the middle of the every fin drill bit back side, with bolt adjunction one reaming piece, thickness decide as required, because of being the usefulness of digging a well on shallow bore hole and soft stratum, so reach requirement of strength fully.Fin drill bit inboard is welded with lower connecting base and connecting rod base.

Described hanging is welded after cylinder is rolled by the 10mm steel plate, and top adds clamping ring of weldering, has eight screwed holes, adds a circular medium plate more thereon, connects with screw.Open a circular hole in the medium plate center, weld a sleeve therebetween, hexagonal cover and liner in the cross are housed in the sleeve, three steel balls are housed respectively on six planes.Interior hexagonal cover top adds rubber cushion and pressing plate and fastening with screw.Central shaft tube is directly contacted with steel ball, reduced the frictional force between them greatly, guaranteed the central axis activity freely.In addition, in hanging four fin drill bit upper connecting bases of cylinder bottom welding; Four fin gooseneck brackets are welded on top, and are symmetrically welded four shoulder pads on its lateral surface top.

Described linkage comprises connecting rod, regulations and parameters crossbeam, suspension rod and relevant hinged seat composition with them.Relevant its effect and moving is discussed in the specific embodiment in the back again.

Described cross recess device down is with behind the super-thick steel plate fluting, is cross-wire weld and is connected on the thick central tube.In order to reduce the frictional force of it and connecting rod, with fixed frame of bolt, both sides respectively are equipped with a movable drum with thick bolt dress in the frame, and connecting rod is directly contacted with it in the outside, its underpart, and this has also reduced the frictional force between them greatly.In addition, in a band cross shoulder is respectively installed in cross recessed central tube upper and lower the hexagonal cover so as to transmission torsion.

Described flap-like drill bit is opened locking mechanism by last cross recess device, shrinks push rod, and retractable joint pin and spacing welding annulus are formed.Last cross recess device also is with behind the steel plate fluting, be cross-wire weld be connected in hexagonal put, and have circular hole in the appropriate location, middle part.Between spacing welding annulus and the outer-hexagonal axle very wide space is arranged, wherein, fix upward cross recessed position with it with scolder filling welding.

Central shaft tube connects top non-rotating structure and bottom rotating part.The whole piece axle all rotates, and forms by three sections, and upper and lower is circular central siphon, and the middle part is up big and down small outer-hexagonal oblique crank Z pipe.Following central siphon bottom separates with starter of thread connection, welding side, drill bit bottom bar, and studs with alloy sheet.There is one section to be cut into the square pipe near following central siphon and drill bit join, is convenient to the flap-like drill bit and closes up.Its effect also has other purposes in addition except that guide-localization, be exactly can concentrate this aperture to all residual quarrels when playing reverse circulation drilling, is convenient to gravel pump they are discharged the face of land.If adopt the direct circulation method to creep into, in the hole flushing process behind whole hole, all the time can residual a small amount of residual quarrel, and this guiding aperture just in time is their concentrated place, this has just guaranteed large-area " cleaning " at the bottom of the hole.

2, (Fig. 6-Fig. 7): 1) movable inner sleeve: forefathers mainly come transfer torque with drilling rod or reaction torque balanced controls to the distinctive inside and outside sleeve pipe of this machine.Here break the normal procedure in person, make the reaction torque balanced controls with sleeve pipe.It is movable why to cry, and is the elasticity of utilizing steel plate, and it can open, and also can shrink, and passing with a little water pipe specially just becomes sleeve pipe after connecing the circular hole of buckleing.I once used two blocks of steel sheets to make movable inside and outside circle, supported with yoke, and middle concrete is done three meters heavy caliber open caisson constructions then.This has just proved its feasibility.

2) seal fixed jacket pipe preferably: its main and movable inner sleeve is used.Be suitable for for special bad ground and operation at sea.

3, chuck (Fig. 9-Figure 10): the designed inside and outside sleeve pipe of this machine need not be threaded, because of diameter big be not easy to implement, processing is also had any problem.Simultaneously, can strengthen own wt if the whole thickness of sleeve pipe increases, let alone utilize its elasticity to carry out bending.So, have only the steel sheet of utilization to do casing main body, at its outside welding muscle sheet, the big more muscle sheet of diameter just should be more more, are symmetrically welded six here then.Open some transverse grooves in appropriate location, every upper and lower position of muscle sheet again, just solve their joint and hang the own wt problem by these grooves.The chuck here designs in order to address these problems exactly, and it both can make sleeve engages or take off pine, also can hang total weight.In addition, it can also be pressed into simultaneously or rise and pull out bilayer sleeve.

4, sleeve pipe is carried frame (Fig. 8): this is the corollary equipment of this patent, designs for hanging inside and outside sleeve pipe specially.Structure is still calculated simply, and is easy to operate.It is hung in the elevator bottom of generally creeping into usefulness, can arbitrarily rotate.Omitted a bit because of the length relation on the figure, between two hook annulus (195), should add a loop chain (254) exactly---see Figure 13, length is more than 2.5 times of every joint casing length.

5, (Figure 12-Figure 13): for personal safety, the aperture must add guard ring for aperture guard ring and inner sleeve drag hook.But be not only here for this purpose, also have other purposes.After mentioning the inner sleeve contraction above, its diameter reaches and the outer sleeve inner wall distance does not all have strict regulation, has given to pull out and has brought certain difficulty.For head it off, on the ring beam of the top of aperture guard ring, hang six drag hooks here with loop chain.The drag hook axis can arbitrarily rotate, and there is a baffle plate front, as long as after making baffle plate pass the slotted hole at sleeve pipe muscle sheet middle part, rotate 90 ° rapidly, twists the double end riffled tube then, and drag hook will soon be locked inner sleeve.At last inner sleeve is hung on the top ring beam of guard ring.

6, with regard to difficulty how water pipe and cable saddle (Figure 14): the water pipe of forefathers' diving pile driver is hung with suspension hook, and lifting is still calculated conveniently in short distance, but will make continuously long distance elevating.This patent design has the water pipe hoist engine, and in addition, forefathers have had cable reel.In order to cooperate their use, so designed water pipe and cable saddle here.Its effect has two aspects, and the one, when under the stake machine in the hand-hole time, loosen winch and the hoist engine system of stopping, then saddle can turn automatically, the alignment hole center, simultaneously, they can follow a machine to slide automatically.The 2nd, when quarrel is unloaded in the lifting of stake machine, must start cable reel and water pipe hoist engine this moment, when the stake machine rises to the top, as long as pushed up saddle, so it just turns again, close down winch and hoist engine this moment, the discharging tower unloaded quarrel near the stake machine was transferred to, certainly also and then in the past, at this moment the guide wheel of saddle plays support and guide effect for water pipe and cable.

7, water pipe twist preventing apparatus (Fig. 5 top): the stake machine can not rotate in sleeve pipe, can only slide up and down along gathering sill.And the water pipe hoist engine is let slip in the journey at volume, and it can make water pipe self rotating certain angle.Go down like this and must turn round water pipe bad.In order to address this problem, so be added with a water pipe twist preventing apparatus towards grabbing brill stake machine top.Mainly the rubbing action by bearing and sealing ring makes two-part action up and down separately.

8, bore enlarging aiguille (Figure 15): forefathers' stake machine has multiple brill enlarging aiguille, and last open type, bottom-open type are arranged.But better simply all is single reaming usefulness, and can not play positive and negative circulation.Bore and expand dual-purpose complexity, even use hydraulic control, the straight-through down-hole of oil pipe is very inconvenient.So I have done some improvement to forefathers' drill bit here.Last free bearing is fixed on central tube top, and following free bearing is removable, with its displacement of hexagonal cover qualification, so just can obtain maximum reaming or contraction state.Creep into fin and all can remove, can creep into separately or reaming, also can creep into simultaneously and reaming, also can play positive and negative circulation with expansion end fin.But it can not use separately, must combine and could use with a stake machine.For solving reaming problem midway, increase a reversing tripod reaming hanging basket in boring the enlarging aiguille bottom here, it with bolt in creeping on the fin holder.

9, a tube two-in-one drill bit (Figure 16) is taken out in impact: top mentioning towards grabbing the brill main frame also has impact function, but is not main, only suits to use in some softer and firm stratum.It is just inapplicable for loose, as to contain big gravel stratum and hard base rock.So designed an impact here and taken out the drill bit that tube is combined as a whole.So long as more firmly needn't cased stratum, no matter be soft, hard can creeping into.Some resembles shape towards the tooth cross bit, but structurally difference is very big.At bucket of cross bladed sheet top welding, four valves alive are arranged at the bottom, weld four permeability cells near the central tube place in the bucket.Remove in addition, sword sheet outer rim is also welded one and is repaiied the hole circle, forms a big down circlet shape space (middle separated by the cross steel plate) of going up between it and the bucket.When drill bit descended rapidly, the volume of bottom flushing liquor and useless quarrel also expanded rapidly in the hole, rose along the valve of living, permeability cell, annulus so just force them to overcome gravity; Fall under gravity into again at last in the bucket, carry out secondary at the bottom of so just avoiding some big landwaste to stay the hole, impact for three times.Also because such three gas permeable devices are arranged, this has just reduced the resistance that drill bit descends greatly, thereby has improved impact capacity simultaneously.Boring connects the pressure pipe of growing tall towards the face of land, available positive and negative circulation hole flushing after finishing.

10, hand or electronic water pipe hoist engine (Figure 17); " modern basic engineering construction " textbook was mentioned the water pipe cylinder, but how unclear in person structure is, also is others' patent even if having.But from the water pipe of forefathers' stake machine all is to hang with suspension hook, also not too suits to come folding and unfolding with cylinder.So designed the water pipe hoist engine that can hand also available motor drives here in person.Purpose is to want high-voltage tube is twisted on the reel, at any time can folding and unfolding, save the labour greatly.But reel rotates, and can not rotate towards suction, the gutter in jet pump or pond.In order to address this problem, so must add a twist preventing apparatus in reel axis row, water inlet pipe outer end, the flushing liquor that sucks or discharge communicates with at the bottom of the hole continuously through bend pipe and high-voltage tube.Driving reel can directly be driven by pulley concial disk, but rotating speed can not be too high, must be the electric current input motor after the process frequency conversion.The design also need solve the other problem, if boring is dark more, it is many more that reel is rolled up the high-voltage tube number of plies, and skin and internal layer linear velocity all have difference.The decline problem of high-voltage tube fortunately solves, and is then relatively more difficult as it and wire rope are risen synchronously, probably also will increase quite a lot of equipment.But adopt simple artificial control method here, outside gearcase, add the friction pulley of a band triangular groove on driven gear shaft, wheel adds a wedge shape friction wooden unit down again, controls the ascending, descending speed of high-voltage tube by it.On driven shaft, friction pulley also adds a bicycle pin arm outward, can also replenish with hand in case of necessity.

11, manpower retractable horizontal stand (Figure 11): the water pipe hoist engine that designs above has advantage, but also shortcoming is arranged.Advantage has following several aspect: the one, guarantee energy continuous sucking or conveying flushing liquor in drilling process; The 2nd, can make high-voltage tube follow a machine to a certain extent and slide automatically; The 3rd, in the high-voltage tube lifting process, no matter hand still driven by motor all saved the labour greatly.Shortcoming mainly contains following two aspects, the one, in lifting process, be difficult to control the synchronizing process of high-voltage tube and wire rope, the 2nd, when playing reverse circulation drilling, a large amount of gravel fragments is made long distance and is flowed in the pipe of bending, will certainly accelerate the wearing and tearing of tube wall, it is big again to be subjected to resistance simultaneously, even clogging can occur.Infer it is so in theory, if no problem through facts have proved, that just can relievedly use.But, don't work clear water or mud beat direct circulation creep into then definitely no problem.

Here more thorough in order to consider a problem, simultaneously also be that figure is convenient, so designed manpower folding and unfolding water pipe platform, be " 8 " font at this platform upper hose and curl and keep flat.At first its radius has increased, and the flushing liquor of band silt and rubble roughly flows on same horizontal plane, and this is just more unimpeded easily.While water pipe one a positive warp song, the angle that it reverses is cancelled each other, and the torsion phenomenon that this has just eliminated it has prolonged application life.But its shortcoming is to have increased physical labor intensity.Also folding and unfolding like this of cable in fact, much more simply.

12, discharging tower funnel lower cylinder switch (Figure 18): the discharging tower that this machine uses and funnel and forefathers' is basic identical.Different is that funnel top is equipped with a discharging tower guard ring, and the guard ring bottom has the movable block in eight portable plates and the chuck case basic identical, can strengthen or dwindle bore within the specific limits.The stake machine can arbitrarily put down and can both push up the shoulder pad of hanging the cylinder outside, unloads useless quarrel.Be the not accompanying drawing of saving space.But the switch of forefathers' funnel bottom thinks that not too being fit to this machine uses.Plate switch commonly, useful lever pushing; Also useful bolt promotes.It is the most suitable for some clays and tiny homogeneous substance, but for the uneven stone of some sizes, particularly ratchel is inapplicable.The cement paste facilities of mix storied building of modernization construction plant is then used the open and close of hydraulic-driven loose-leaf.Need bigger motor and hydraulic pump like this, though reliable, increased engineering cost.So I design a drum switch here in addition.Get two short seamless pipes, central cut-out wherein half, two ends stay small part.Make them do to roll relatively then, crack, switch opens when forwarding the part that is cut to, just occur along periphery; Two cylindrical surface is in contact with one another when not cut partly when forwarding to, can only do relative rolling, and this moment, switch cut out.If cylinder clockwise direction on its right is rotated, then two cylinders always upwards promote and open, so all landwaste and stone all do not stop their rotation.

Four, description of drawings patent of the present invention has 18 figure, does not have so much originally.Because of whole stake body is long-pending bigger, more complicated again simultaneously, if ratio contract the too little Chu that just at all do not see.Come picture for three sections so be divided into upper, middle and lower, the structure chart that has simultaneously also will be drawn left view or vertical view and just can see clearly, if then be a figure on a figure except that drawing front view; If a view is arranged on other a piece of paper, then is considered as another one figure.

Five, specific embodiment most preferred embodiment of the present invention is such.Comprise by dashing to grab and bore main frame, inside and outside sleeve pipe, chuck, sleeve pipe and carry frame, aperture guard ring and inner sleeve drag hook, water pipe and cable saddle, water pipe twist preventing apparatus, bore enlarging aiguille, impact 12 most of compositions such as taking out the two-in-one drill bit of tube, hand or electronic water pipe hoist engine, manpower folding and unfolding water pipe platform, funnel lower cylinder switch.

1, dashes to grab and bore main frame preferred forms (Fig. 1-Fig. 5): known to above-mentioned, this facility have and dash, grab, bore function, different fully with the structure of conventional piles machine, it does not have unit head, do not have drilling rod but play with wire rope, gathering sill with inner sleeve is used as the reaction torque balanced controls, sleeve pipe and drilling rod are combined together, and inner sleeve also can be used as and feeds usefulness in case of necessity.The power that drives rotating shaft is common threephase asynchronous, it is placed directly in the closed chamber of down-hole, does not establish gear, mainly utilizes the modern high technology product---and frequency converter is realized the speed change of motor, much more flexible like this, different rock-layers can be crept into different rotating speeds.Put two among the figure in the closed chamber respectively for the motor of 7KW, not enough as power, can also increase a closed chamber, increase by two same motor again.The centre shouldn't circular steel plate, directly connect with screw between two clamping rings, but the centre will add sealing mat.This machine drives opening, closing of fin drill bit without hydraulic pressure, and because of it rotates, hydraulic pump is placed on the face of land or the down-hole is all inconvenient.And utilize lever principle here dexterously, connecting rod (8) upper end is articulated in lever crossbeam (9) middle part; The lower end is articulated on the fin drill bit connecting rod base (14).Regulations and parameters crossbeam (9) one ends are articulated in down cross recess weldment (7) top; The other end is articulated in suspension rod (10) bottom.Suspension rod (10) upper end is articulated on the gooseneck bracket (11) of hanging cylinder (22) top.Fin drill bit top is welded with lower connecting base (13), and its (13) is articulated on the upper connecting base (12) of hanging cylinder (22) bottom.

Fig. 1 is the contraction situation of stake machine when lifting.When normally creeping into, should shrink push rod (47) to the fin drill bit at middle part and take away.Then its gathering sill (162) along movable inner sleeve (160) is slowly put down, but the stake machine side's of guiding bar (62) should not hang saving sealing of gathering sill (174) under the movable inner sleeve at last, also should keep a segment distance.At this moment, when the electric current of connecting through frequency conversion, two or four small size motors (66) just press the desired speed clockwise direction and are rotated, and two driving gears (63) drive driven gear (64), so whole piece central shaft tube (69), (4), (3) also and then rotation.Because the drive of (49), (37), (5) interior hexagonal axle sleeve is arranged, so comprise friction cylinder (51), below be rotating part, more than be non-rotating structure (going up except the central shaft tube (69)).The stake machine has following two kinds of situations when beginning to creep into, and the one, the no residual quarrel hole in, after starter (1) time arrived at the bottom of the hole, weight disappeared at once on the electronic scale.This moment, the fin drill bit still was closure state (under situation at a slow speed, centrifugal force is less), did not also begin to creep into, and only after starter (1) creeps into 180mm (different bores this apart from difference) earlier, just began to creep into when it touches the rock stratum.The 2nd, have more residual quarrel in the hole, starter (1) also at the bottom of the no show hole fin drill bit just be subjected to resistance, just the weight of bottom rotating part is pressed on the residual quarrel, reflects that on electronic scale weight slowly reduces, until being zero.In the above two kinds of cases, starter (1) is though only bearing the weight of top non-rotating structure when creeping into, and this is enough, increases steel plate again in increasing the weight of the chamber inadequately.Also, under the significant stress effect of top, at first carve and get the rock stratum because its (1) and stratum contact area are less, force the whole piece central shaft tube to descend, thereby make down cross recess weldment (7) also be with lever crossbeam (9) one ends to descend, oppress the fin drill bit, it is slowly opened by connecting rod (8).Lever crossbeam (9) reaction force that the other end produced promotes to hang cylinder (22) by suspension rod (10), alleviated its weight to a certain extent, but this weight is added in still all the time on the connecting rod (8).The weight of last top non-rotating structure is added on fin drill bit and the starter (1) simultaneously.Central shaft tube constantly descends, and connecting rod (8) constantly promotes the fin drill bit and expands outwardly.This moment, the weldment (29) on its right was more owing to protruding flap edges, see from vertical and horizontal direction and all to be wedge-like, and the tangential rock of scarf of its (29), so be set in the top alloy sheet (2) in its (29) continuous rock cutting under the immense pressure effect; Fin behind weldment (18) outside at middle part also studs with alloy sheet (2), also can rock cutting in rotation, and constantly landwaste is pulled out the center of moving by the fin skin.Can see from face of land depth gauge, when the stake machine after falling at the bottom of the hole, if have under the residual quarrel situation, illustrate then that as falling 180mm again the fin drill bit has opened up into to greatest extent, this moment, it was outward-dipping a bit, but its outside the right side (29), in (18), a left side (30) weldment be vertical, so the hole that comes outbreak out also is vertical.If under the situation of not having residue at the bottom of the hole, the fin drill bit just opens up into to greatest extent in the time of then will falling 180 * 2mm on depth gauge.Theory is like this, actual at work difficult the grasp.Generally speaking, after seeing the 180mm that descends on the depth gauge, should bore, or else can descend up to it just should stop to creep into more again.Be not flat at the bottom of the hole in the hole that at this moment comes outbreak out, it roughly along the α track rock cutting of Fig. 1 or Fig. 2 bottom, can describe that some slowly swells to the centre from hole wall as volcanic cone with simple image, there is individual hole at the center.

The sense of current after changing frequency conversion, motor can drive the central shaft tube counter rotation, and the fin drill bit also and then rotates in succession.Because the weldment (30) on its left side does not protrude the outer edge of fin, see from level and vertical direction also to be wedge-like, but its scarf slopes inwardly.So when fin in counter-rotating time because the existence of medium, it just can produce a kind of pressure of inside contraction, but differ it is closed up.The fin drill bit that only reverses on one side, on electronic scale control weight (top non-rotating structure, or more bigger) and on depth gauge be controlled at the scope of 180mm in slowly promote machine on one side.At this moment, do not influence the bottom in the ordinary course of things and rotate partly, have only central shaft tube up to move, thereby driven lever crossbeam (9) the inner and connecting rod (8) rising yet.So it just produces the active force to in-draw to the fin drill bit.Owing to hang cylinder top and descend cross recess weldment (7) bottom that tourelle all is housed, reduce the frictional force between them as far as possible.So the suffered pressure of fin drill bit does not only reduce, some (leverages) have been increased on the contrary.Under this two power synergy, the fin drill bit does not leave at the bottom of the hole all the time, shrink on one side but be arc shaped (seeing Fig. 1 or Fig. 2 bottom b track), on one side the alloy sheet (2) inlayed with its left side internal layer cut " volcanic cone " projection, cut down landwaste and constantly be involved in the center by the fin skin.If creep at softer sand layer, in this two power effect next grab just can be loose.After steel cable was increased to 180mm, four fin drill bits closed up fully in the pre-processed tetragonal prism of lower center tube (3)." volcanic cone " that protrude this moment almost scabbled, and this has just finished the native process of grabbing.If continue to promote the stake machine again, it just can leave at the bottom of the hole, until from inner sleeve, proposing outside the hole, drop it off at last on the custom-designed discharging tower, eight portable plates of funnel guard ring bottom can push up the shoulder pad (28) of hanging cylinder (22) outside at any time, loosen wire rope again, open automatically at top weight effect lower panel drill bit, useless quarrel is unloaded on funnel or truck.Promote steel cable then and repeat said process.

This machine designs lifting appliance voluntarily.Mainly form by promoting tower, flat car and track.Promote some picture of tower tower crane for building now, but structure there is very big difference.Less, general≤120 ° because of the angle requirement that it rotates, so add a vertical rotation axis, in the rotating shaft three guy wires at the top, purpose is to increase hoisting power, the trial period can be used crane lifting.Promote the tower except that being fixed with on the flat car, percussive drill jacking equipment (duration of test the most handy others scrap rig reparation), electronic scale, depth gauge, variable-frequency governor or the like also are installed.Platform trailer frame is fixed on it on the rail when creeping on railway.In addition, the pump suction that forefathers use is installed in the next door, aperture---spray anti-recycle unit, high-pressure hydraulic pump and power-equipment etc.Pump is inhaled---and spray anti-recycle unit,, creep into but also can play direct circulation as the term suggests can play anti-circulation.Mainly jet pump and gravel pump are combined.As creep into deeplyer, if it is not enough to promote the landwaste ability, also can under the hole, add a gravel pump again, make pump lift to add pump and inhale---spray anti-circulation, at this moment if the degree of depth that will creep into more than the 100m is then definitely out of question.High-pressure hydraulic pump is geologic prospecting party used (BW600/20) three cylinder reciprocating double-action horizontal slurry pumps, one grade of maximum pump discharge 36m ³/ h; Second gear maximum pump discharge 24.6 m ³/ h.This is a geology with the slush pump of maximum pump discharge, and to advance speed slow because of this machine drill, so centering, small-bore machine are enough.Its main effect has the following aspects: 1/ can be connected with four little water pipes of inner sleeve inwall, and available in case of necessity high speed flushing liquor (water or mud) helps the cutting rock stratum.2/ common used direct circulation method is crept into, and flushing liquor is just in time opposite, inhales from pump---suction (quarrel) pipe that sprays anti-recycle unit enters high-voltage tube, at the bottom of the hole of flowing through after, again from boring annulus return the aperture, enter sedimentation basin then.But workbench here and sleeve pipe 2-3m above ground level.Platform also has workman's operation down.So definitely can not allow flushing liquor flow out from the aperture.Preferably put down the suction water pipe of slush pump in the hole this moment, under the situation that guarantees the suction journey, it lowerd as far as possible, is convenient to draw more coarse grained landwaste, puts into sedimentation basin through its gutter again.3/ as creeping into anti-round-robin method, then must be from aperture irrigation liquid.Here an available other short high-voltage tube, one terminates on the drainage joint of slush pump, and the other end puts down in the hole, starts slush pump again, and flushing liquor just enters in the hole continually.At this moment, inhale if start pump simultaneously---spray anti-recycle unit, then under the huge suction in top, the flushing liquor of band landwaste just is inhaled in the high-voltage tube through starter, rises to the suction quarrel pipe of anti-recycle unit, flows into sedimentation basin through the deslagging pipe again.4/ under no sleeve pipe (except the orifice tube) situation, and as creeping into impacting (main frame or dash and take out drill bit) method, the flushing liquor of direct circulation this moment can flow out from the aperture, flows into sedimentation basin then.For not making high-voltage tube and cable lay winding wire ropes when impacting, so, just should unload them in advance, the high-voltage tube lower end also should be stayed under the hole, but will be with main frame or towards taking out drill bit maintenance certain distance.At the same time, other gets one section short high-voltage tube, and one terminates on the drainage joint of slush pump; The other end is also received on the drainage joint of water pipe twist preventing apparatus of hoist engine.So just can guarantee that the high speed flushing liquor arrives lower in the hole at any time, strengthen the last i of landwaste, than becoming stronger from replenishing flushing liquor near the aperture.Connect high-voltage tube or cable behind the whole hole, reduce the water pipe of the drainage joint on the water pipe twist preventing apparatus of hoist engine simultaneously, replenish flushing liquor from the aperture with slush pump again, carry out hole flushing with regard to available anti-round-robin method afterwards.These all are forefathers' products, do not belong to the art of this patent, and all do not have accompanying drawing.But in implementation process, be absolutely necessary, here incidentally.

This machine can have following purposes under the sleeve pipe situation not having.As the stake machine is hung on the custom-designed discharging tower of this patent, top is not rotated partly and is dropped to minimum point, and four folding and unfolding joint pins (44) just in time are enclosed within the groove of cross recess weldment (50).This moment, the hole of two parts just in time aligned, and wears a long spiral shell spokeless wheel (46) then they are fixed, and made four fin drill bits just be in open state forever.Preferably change a cross bit that diameter is bigger simultaneously again in the central shaft tube bottom.The pressure pipe of growing tall (150) of temporarily removing cable (133) in addition and leading to the face of land also need be changed the impact elevator at last.Just can carry out percussion drilling on softer firm stratum this moment, directly comes guard aperture with mud.Though rigidity, the intensity of stalk and axle are all better, stroke is also unsuitable excessive.Best drilling method is, high-voltage tube (150) is directly put down the hole at the bottom of, but also a segment distance should be arranged from the stake machine, send down lowest part mud with high-pressure pump again, the promptly first direct circulation percussion drilling of using as far as possible.Connect high-voltage tube (150) behind the whole hole, with anti-round-robin method hole flushing.The method environmental pollution is bigger, and condition does not allow and should not use.

2, (Fig. 6-Fig. 7): 1) movable inner sleeve: it is rolled and is formed by 4-6mm (window footpath size is decided) steel plate inside and outside sleeve pipe preferred forms, but is an inclined-plane at seam crossing, does not add welding.Be called sleeve pipe and open and close line (171).Open and close line (171) upper left-hand welding short circuit in internal surface of sleeve pipe and buckle (161), the long button (163) that connects is gone up in the right side welding, and quite go up long connecing and buckle (163) position and open a slot opening and closing line (171) left side, go up the long button (163) that connects when shrinking along this hole slip for sleeve pipe.Simultaneously also buckle (161) in opening and closing line (171) lower left side welding short circuit, the right side welding is the long button (172) that connects down, and past left side opens a slot, and this two connects the just in time opposite of the position of button and top.Connect and all have circular hole between smashing, pass behind little water pipe (165), (176) just packaged tube.But some is different for the short circuit button (177) that sleeve pipe descends joint (173) foot most and the short circuit button (161) on top.Its hole is classification, and water pipe can spur at this but can not rotate.Connect the same short circuit button (161) of upper and lower welding of the approximate cross symmetry of button with switching, but the short circuit button (179) that sleeve pipe descends joint (173) foot most and top is different, its circular hole is a screwed hole.This three row connects button equally with little water pipe (165), (178) cross-under, but next root (178) bottom for being threaded.The little length of pipe casing length of making peace greatly equates that only it has had more connecting thread part (except first water pipe in bottom), and upper and lower all is tapered thread, and every water pipe top must be sunk to short circuit and buckle (161) small part, is convenient to engage one another between sleeve pipe.Little water pipe top can be connected with high-pressure hydraulic pump, at the bottom of the flushing liquor direct perforation, accelerates rate of penetration and makes partly useless quarrel concentrate central tube (3).In addition, the torsion some between upper and lower sleeve pipe is come balance by these four water pipes.

In addition, in the specific symmetric position of an internal surface of sleeve pipe gathering sill of each continuous welding (162), (174) bottom lock bottom.Cell wall adds the cushions, and is easy to after the wearing and tearing change.Usefulness for stake machine guiding and counter balance torque.

Split in the sleeve pipe middle part in order to prevent closed line (171), so nail (164) is shunk in two pairs of appropriate location, both sides welding at it, every nail has an aperture, behind every pair of binding iron wire, near passing aperture extraction tube outer wall, again it is tightened, link up with iron wire again between every pair and the every joint sleeve pipe then.Its effect, the one, tighten every joint sleeve pipe, the 2nd, help sleeve pipe to shrink explanation more below.

Sleeve outer wall is symmetrical hexagon welding six muscle sheets (167), and the appropriate location, upper and lower of every muscle sheet has three kinds of transverse grooves.A kind of for sleeve engages and hang own wt and use; The another kind of chuck that supplies twists and hangs usefulness; The transverse groove of side exists only in the top of muscle sheet, for putting forward the usefulness that frame is hung.In addition, the middle part of every muscle sheet has a Long Circle hole, and passes sleeve pipe, shrinks the usefulness of post-tensioning hook block extension for sleeve pipe.

Every joint casing length is unsuitable long, is advisable with 800-1200mm.It is not flexible to have grown inner sleeve.Be difficult to shrink.Simultaneously, need when being lowered to sleeve pipe earlier after three of ground adjunctions under the ability in the hand-hole, this has just increased height of table.

Generally speaking, in drift sand formation with contain the stratum of sposh and be used with outer tube during operation on the water, they are nested together mutually, and inner sleeve saves muscle sheet (175) bottom down a projection (180), and its (181) can not be slided.So in the short time of following bilayer sleeve, inner sleeve will bear the total weight (will deduct the frictional force between outer tube and rock stratum certainly) of outer tube.Behind the whole hole, as long as near the little water pipe of that root (165), (176) the closed line (171) are pulled out, then sleeve pipe (160), (173) will be shunk (because of being full of silt between inside and outside sleeve pipe) automatically, and maximum can make more than the reduced 60mm.As not reaching purpose then with carrying the iron wire that frame spurs sleeve outer wall gently, it will draw in from top to down.Continue adjunction and depress outer tube this moment, cuts off drift sand formation.Before being lowered to reinforcing cage, rise earlier and dial inner sleeve, concrete perfusion on one side then, rise and dial outer tube on one side.

When creeping on the not too serious stratum of some avalanches, only inner sleeve is just enough down.But this moment, boring aperture was bigger than casing diameter, caused sleeve pipe and hole wall zerofriction force, and is moving in vain when creeping into.The head it off method is as follows, after earlier three sleeve pipes in bottom being connected, because of a slotted hole is all arranged in the middle of every muscle sheet, with regard to this hole with long angle steel of bolt, the slightly larger in diameter that makes it is in bit diameter.Even if there is a small amount of gravel or the sillar problem that falls down also little in creeping into, it plays the fixed sleeving effect on the contrary.Boring is lowered to reinforcing cage after finishing, on one side concrete perfusion, rise on one side and pull out sleeve pipe.In order to strengthen the antitorque of every joint sleeve pipe and to hang ability, respectively add a weldering little clamping ring (170) in the appropriate location, upper and lower of muscle sheet both sides, be convenient between two joint sleeve pipes, reinforce with long bolt.

2) seal preferably fixed jacket pipe (Fig. 6-Fig. 7): after it is rolled by 5-8mm thick (depend on diameter decide) steel plate again through being welded, all there is the length of 50mm every joint sleeve pipe upper and lower as overlapping partly, also can put rubber cushion or filler in case of necessity, make its sealing performance better.Its internal diameter is advisable with 4mm than the big 4-6mm of muscle sheet external diameter of movable inner sleeve.Every joint length should be consistent with inner sleeve, but next joint has then been lacked a lot, and reason has two, and the one, the projection of the muscle sheet of inner sleeve pipe to support; The 2nd, cooperate the slide position of making up chuck.Outer wall is symmetrically welded with the consistent of six muscle sheets (169), (182) thickness and size and inner sleeve equally, and radius is difference slightly, but can ignore.The transverse groove that the appropriate location, upper and lower is opened is consistent with inner sleeve muscle sheet also, and slotted hole is not opened at the middle part only.Do not use separately generally speaking, many and inner sleeve cooperates in the following hand-hole.Be specially adapted to bad ground and operation at sea.Also must be lowered to bilayer sleeve for the high-quality stake of ask for something hole.

In order to make internal and external casing be linked to be an integral body, be unlikely to produce relative rotation, increase its twisting resistance.Must descend the inwall of joint to be equivalent to the position of projection (180) most in outer tube, with groove of two blocks of steel sheets (166) welding, projection (180) just in time is embedded in wherein, it be no problem to make them do upper and lower activity at least in an adjusting range.

Above-mentionedly dash, grab, bore a machine and cooperate inside and outside sleeve pipe that following multiple drilling method can be arranged: 1) double braid covering pipe bit method.Be suitable for operation at sea and at loosening sand, drifting sand layer or contain in the stratum of sposh and creep into.As meet midway harder limestone, schist, shale, and siltstone etc. also can creep into, but drilling speed is very slow.This method can not need clear water or mud guard aperture, at the bottom of only needing four little water pipes of flushing liquor (water or mud) by the inner sleeve inwall to be directly injected to the hole with high-pressure pump (geology usefulness), one helps cut broken rock, and two come the guard aperture wall, and the 3rd, landwaste is diluted to pasty state.If viscosity also can drop into mud ball from the aperture inadequately, be convenient to grasp.If water level is higher in the hole, then needn't can directly creep into extracting by little water pipe jet douche liquid.This is a kind of drilling method of environmental protection.The most suitable water-deficient area.

2) the individual layer inner sleeve bores method.With last different be, the stratum is slightly firm, and only the individual layer inner sleeve just can be dealt with problems down, but descends the outside of the sleeve pipe muscle sheet of 2-3 joint must be equivalent to the angle steel of outer tube thickness (width) with bolt most, to increase the frictional force on it and stratum.This method is available water or mud guard aperture in case of necessity.But inapplicable operation at sea.

3) single, double layer Sleeve drill grabbed positive and negative circulation drilling method.This machine is furnished with direct circulation and reverse circulation drilling equipment.For save the fin drill bit after grasping landwaste ascending, descending and unload time of quarrel.So when rotating, seeing on the depth gauge that steel cable has risen behind the 180mm (different bores this apart from difference), proving that the extracting landwaste finishes from fin drill bit counter-clockwise direction.Can continue up to promote short distance this moment again, and purpose is to make the fin drill bit exceed residual quarrel face bottom.Continue again then the stake machine is put down, begin the drilling process of another round trip.The landwaste that caught this moment constantly is scattered.The way that solves, the one, slow down a machine decrease speed, the 2nd, strengthen positive and negative circulation pump amount, make landwaste be discharged into the face of land rapidly.The stake machine constantly down creeps on the one hand continuously like this, constantly with direct circulation or anti-round-robin method landwaste is discharged into the face of land on the other hand.If the environmental protection condition permission, these several drilling methods are the most easily.Rate of penetration is also than comparatively fast.

4) impact positive and negative circulation drilling method in the single, double layer sleeve pipe.When the stake machine under the lifting situation, the bottom is rotated partly and is fallen to minimum point, last cross recess weldment (50) and folding and unfolding fore-set (44) are separated into ultimate range.If add a contraction push rod (47) this moment between two parts, upper and lowerly fix, so the fin drill bit is in contraction state forever with long bolt (46).Can grind or at the bottom of the broken hole bulk landwaste, particularly when creeping into, also should impact once soon for a long time with positive and negative round-robin method midway.As creeping into, and change a cross bit that diameter is slightly bigger, can in short distance, dash in case of necessity with short stroke in the central shaft tube bottom than broken ground.But the aperture of rushing out can be little more.Here only way is from four little water pipe high velocity jet flushing liquors, helps the cutting rock stratum.Next is the hydraulic means that utilizes the face of land, depresses inside and outside sleeve pipe or individual layer inner sleeve simultaneously by chuck, so as to helping to repair the hole.With direct circulation or anti-round-robin method landwaste is discharged into the face of land then.As creeping into, must do flushing liquor with mud with the direct circulation method; As creeping into anti-round-robin method, doing flushing liquor with clear water or mud can.Be lowered to individual layer or bilayer sleeve and decide on the steadiness on stratum, individual layer is not suitable for operation at sea.

3, (Fig. 9-Figure 10) and simultaneously be lowered to inside and outside sleeve pipe method (Figure 12): 1) chuck preferred forms: it divides fixed and movable two large divisions to the chuck preferred forms.Fixed part mainly is made up of the upper and lower two circular clamping plate of skin (208), and the outside is symmetrically welded six fan-shaped pads (206) therebetween; The inside edge also is symmetrically welded six fore-sets (207).Wherein open a circular hole in the middle of four fan-shaped pads (206), and pass upper and lower circular clamping plate (208), four conduits (209) from wherein passing through.Movable part also is made up of two circular clamping plate (204), welding rectangular tube (205) and chuck case that approach a bit slightly.The circular clamping plate of internal layer (204) external diameter than the little 0.5-1mm of fan-shaped pad (206) internal diameter about, internal diameter is big or small consistent with outer circular clamping plate (208).Here to make its (204) rotating certain angle,, and between breach center second splint (204), respectively weld one section rectangular tube (205) so symmetry has been opened six breach.Chuck case (Figure 10) mainly is made up of movable block (201), loam cake (202), lower cover (203), both sides welding steel (211), side pressure coil (212) and movable block push rod (213).Be welded in the circular clamping plate of internal layer (204) non-notch position intermediate by six chuck case, it and welding rectangular tube (205) are linked to be an integral body.Movable block (201) can move horizontally in case, and the wearing and tearing back is also replaceable.In the outside of its (201) three holes are arranged side by side, pass lower cover (203) simultaneously.If push rod (213) insert this three hole any, then movable block (201) is in contraction state.Open four holes in chuck case lower cover (203) by different distance in addition, make movable block (201) push in the transverse groove that both can tighten inside and outside sleeve pipe muscle sheet, also can tighten muscle sheet outside any point, then push rod (213) is fixed in the hole of lower cover (203).Sometimes movable block (201) is pushed in and may temporarily not reach the muscle sheet, but six advance same position simultaneously after, then the groove of movable block (201) front end just just in time snaps into the muscle sheet.Next door, the chuck case outside is welded with a pressure coil (212)., promote to the left or to the right after packing into this pressure coil (212) with pressure, can make circular clamping plate of whole internal layer (204) and chuck case rotate 19 °.Joint for sleeve pipe can satisfy fully, and the big more displacement of radius is big more.Preferably six roots of sensation pressure but minimumly can not be less than three promoting simultaneously generally speaking.Though this trouble, the success of the test back adopts hydraulic control all right.If want to make chuck case to maintain static, then as long as in welding rectangular tube (205) position, the hole of the circular clamping plate of ectonexine (204), (208) is aligned after, add latch (210) just can reach purpose.

Here She Ji chuck just has not been for the joint that solves sleeve pipe and has hung the own wt problem, it can be risen simultaneously dial and be pressed into bilayer sleeve.Like this, single chuck is not enough, even also wants two to combine, and will divide three places that (Figure 12) is installed on casing support.One place, bottom is welded together by two single deck tape-recorder dishes, make the movable block (201) of upper and lower chuck just in time snap into the transverse groove of inside and outside sleeve pipe muscle sheet.It is fixed on the axle of telescoping cylinder (226).Except that engaging or separate the inside and outside sleeve pipe, also can depress or rise group inside and outside sleeve pipe simultaneously.A middle place is also welded together by two single deck tape-recorder dishes, but it hangs telescoping cylinder (208) axle (comparable bottom oil cylinder is smaller) down, and mainly engage or separate inside and outside sleeve pipe with it, but its depressing or rising booster action group is also arranged sleeve pipe.This two places chuck is all done upper and lower move on four conduits (209), their displacement should 〉=length of every joint sleeve pipe.One place, top is single chuck (229), is fixed on the stent cover by big nut (230).Be lowered in the short time of bilayer sleeve, all chucks of bottom (225) all will get loose, and this moment, inside and outside sleeve pipe total weight was worked to hang in its (229).

2) be lowered to the method (Figure 12) of inside and outside sleeve pipe simultaneously: carry frame (Fig. 8) with sleeve pipe and hang down earlier joint (173) under the inner sleeve, generally speaking with support under lower margin channel-section steel (221) also a segment distance should be arranged, this moment is with card chucking muscle sheet transverse groove on combination chuck (225); Then put down inner sleeve second joint (160) again, make their the muscle sheet position of just in time staggering, again middle part combination chuck is reduced to extreme lower position, the muscle sheet any point that tightens its (160) with the movable block (201) of six lower chucks can, rotate toward same direction then, their muscle sheet is aligned mutually.Near the both sides of the upper and lower muscle sheet the cover interface tube all are welded with clamping ring (170)---see Fig. 6, external diameter of its (170) and muscle sheet consistency of thickness.Between two clamping rings (170), wear, so just increased antitorque between sleeve pipe and hung ability with a long bolt.Put down the 3rd joint inner sleeve (224) at last again, the top fundamental sum rack platform face unanimity of its (224) is just used the position of (Figure 12) middle part combination chuck at this moment, blocks joint (160) muscle sheet on the chucking inner sleeve under using; Use card chucking inner sleeve the 3rd joint (224) muscle sheet, their are engaged after, put on long bolt again.Next step carries the frame outer tube first segment (181) of slinging with sleeve pipe equally, the projection gathering sill that makes its inwall temporarily slides on the bottom combination chuck (225) along the muscle sheet of inner sleeve, this moment, the movable block (201) with top chuck (229) tightened top inner sleeve (224), the upper and lower card of bottom combination chuck (225) simultaneously gets loose, continue to fall joint (181) under the outer tube subsequently, till dropping to inner sleeve muscle sheet projection (180).The upper and lower card that makes up chuck (225) with the bottom this moment tightens the transverse groove of inside and outside sleeve pipe, uses latch (210) to fix upper and lower chuck again.And then just can be lowered to a machine begins to creep into, when creeping into to the degree of depth of suitable casing joint length, top chuck (229) gets loose, and carry frame with sleeve pipe and hang down fixed jacket Guan Shangjie (168), when winching to bottom combination chuck (225), use upper chuck (229) chucking inner sleeve the 3rd joint (224) again, card on the bottom combination chuck (225) preferably only gets loose this moment, fixed jacket Guan Shangjie (168) is continued down on earth, then use card they are engaged one another, use the clamping ring (170) of long bolt cross-under muscle sheet both sides again.Shrink the middle part then and get loose bottom combination chuck (225), and make bottom combination chuck (225) be increased to the position of casing joint length, its upper and lower chuck movable block (201) just in time tightens the translot of inside and outside sleeve pipe muscle sheet, top chuck (229) simultaneously gets loose, the axle of lower sleeve portion formula oil cylinder (226) is shunk, and vertical compression promptly stops down to the degree of depth of casing joint length.Continue later on to creep into, repeat said process.After the problem that is lowered to solved, it was more no problem certainly to promote.

4, sleeve pipe is put forward frame preferred forms (Fig. 8): carrying two last disk (192) and lower discs (193) that medium plate cuts into of frame axis (190) bottom welding, on last disk (192) face, be and be symmetrically welded six and carry set a roof beam in place (191), every two holes are opened in the outer end, use for hanging hook (194), a hook annulus (195) is worn in last hook (194) bottom, in annulus, pass a loop chain (254) then again, see Figure 13, Ben Tuyin compiles and limited not to draw, loop chain length should 〉=2.5 times of every joint casing length.The loop chain bottom is passed a hook annulus (195) again, and overlaps clothes-hook (196) up and down in this ring.Following clothes-hook (196) is made simple, gets a medium plate, overpunching, and the bottom cuts some, stays two nails bottom, just in time can pack into the transverse groove of sleeve pipe muscle sheet side.Also put a rectangular sleeve that is cut out by rectangular tube (197) in following clothes-hook (196) simultaneously, it can upper and lowerly move, but can not withdraw from.In the time will hanging sleeve pipe, promptly rectangular sleeve (197) is up moved, following clothes-hook (196) then exposes two nails, then it is pushed to sleeve pipe muscle sheet side transverse groove, and puts down rectangular sleeve (197), after six muscle sheets all package, can come the sleeve pipe pull-up.Adopt the weight that loop chain can draw the 5-6 ton, six can be drawn the 30-36 ton.If inner sleeve weight, then can be hung the weight of the above inner sleeve of 200m in 0.15t/m.

5, aperture guard ring and inner sleeve drag hook preferred forms (Figure 12-Figure 13): 1) aperture guard ring preferred forms: mainly be made up of guard ring bottom garden ring (234) and top annulus (239), the two is medium plate and cuts out, but on the person should be slightly thicker.Between two annulus (234), (239), be symmetrically welded 12 fore-sets that cut out by medium plate (235), in order to make fore-set (235) more firm, the reinforcing steel ring of making in two round steel of lower outer diameter continuous welding wherein (236).The inboard welding of top annulus (a 239) ring beam of also making (241) by the garden steel.Hang loop chain (254) for convenience, open six small gaps in the symmetric position of top annulus (239) inboard, and it must be in two fore-sets (235) centre position, dividing the angle equally is 60 °.On the ring beam (241) of breach, wear a hook annulus (195), so just constituted the aperture guard ring.

2) inner sleeve drag hook preferred forms (Figure 13); On drag hook medium plate (238), fix a band externally threaded steel pipe of double end (248), wherein pass an axle (247), its (247) can arbitrarily be rotated in steel pipe (248) and be flexible, front end is fixed with baffle plate (249) with key, the rear end adds a radially little bearing (251), and compresses with nut (252).On band double end external screw thread steel pipe (248), put double end riffled tube (250), by bearing (251) and nut (252) drag hook axis (247) is linked to be an integral body, go up a welding hoof ring (253) in nut (252) again by its (250).In addition, drag hook medium plate (238) top is pared down a bit more, and bore a hole, wear a hook annulus (195) in the hole, wear one section loop chain (254) then between upper and lower two hook annulus (195), its length will make the axis (247) of sleeve pipe drag hook probably align the center of the slotted hole of muscle sheet.Here it is so-called inner sleeve drag hook.Specific operation process, put forward the length (Figure 12) that frame is pulled on the inner sleeve after shrinking at one joint with sleeve pipe earlier, drag hook axis (247) probably aligns the center of muscle sheet slotted hole, catch hoof ring (253) with a hand this moment, the quick-moving speed rotation of another double end riffled tube (250), hoof ring this moment (253) does not and then change, but axis (247) stretches out forward fast, after double thread was turned round to the greatest extent, axis (247) had reached to greatest extent.At this moment the length direction of adjusting baffle plate (249) with hoof ring (253) the muscle sheet slotted hole direction unanimity of making peace greatly, then it is pushed in, and make baffle plate (249) rotate 90 ° with hoof ring (253), again with the another hand double end riffled tube (250) that reverses rapidly, till drag hook compacting inner sleeve, after six drag hooks have been operated, cut off or remove original bundle and shrink iron wire on the nail (164), and shed that the muscle sheet is close to the stay bolt of side between two joint sleeve pipes at inner sleeve.At this moment upper and lower sleeve pipe also is engagement state generally speaking, also is not difficult for they are got loose, as long as save each bar muscle sheet energetically in interior promotion with hand, sleeve pipe shrinks the back, and it will get loose automatically.At this moment just can pull on sleeve pipe, be put into the place of parking specially.Repeat said process later on again, until rise pulled out till.

6, water pipe and cable saddle preferred forms (Figure 14): it partly is made up of support and triangle guide wheel two.Support is to go up welding two short forward foot in a step (271) and two long rear feet (270) at base plate (273), and the forward foot in a step (271) is slightly wideer than the rear foot (270), and purpose is that a screwed hole is respectively opened on portion two limits thereon, uses for installation shaft pressure cap (267).Support two upper lateral parts and middle part Welding flat steel or steel plate (274) are reinforced; Front and back then welded steel pipe (272) reinforce.A pull bar (275) is fixed with nut (276) in the rear foot (270) top, and one section cylinder (279) is worn at pull bar (275) middle part, and it is free to rotate, and one section sebific duct (280) is respectively worn at two ends.

The composition of triangle guide wheel is that the edge between two blocks of center circle steel plates (261) is symmetrically welded three little steel pipes (263), make its (261) form an integral body, be symmetrically welded three guide wheel pivoted arms (262) in the edge of both sides center circle steel plates (261) then.Also respectively add a weldering little steel pipe (263) simultaneously in three pairs of pivoted arm middle parts, in two pairs of pivoted arm outsides a horizontal guide wheel shaft (264) is installed respectively, be installed with three circular baffle plate (265) on the axle (264), the centre separates with different length collar (269), and it is again water pipe and cable slideway simultaneously.Guide wheel shaft (264) two ends are respectively installed a radially little bearing (266), between bearing (266) and the baffle plate (265) collar (268) are arranged.Respectively open a screwed hole like this in the pivoted arm outer end, then with being with externally threaded bearing gland (267) that guide wheel shaft (264) is fixed on the pivoted arm.In addition, also in another a hole is respectively left in pivoted arm outer end, pass a transverse axis (264) of growing any simultaneously, its (264) is passed the support forward foot in a step (271) simultaneously.Axle (264) two ends also are equipped with little journal bearing (266), between bearing (266) and the pivoted arm (262) except that collar (268) is arranged, between pivoted arm (262) outside and the forward foot in a step (271) inboard, also have a doughnut (278), use for triangle guide wheel guiding.At last, same with being with externally threaded bearing gland (267) that whole triangle guide wheel is fixed on the support.In order to control the angle that the triangle guide wheel rotates, in selecting the appropriate location respectively to bore a hole near the downside of a pair of pivoted arm of the rear foot (270), and be a steel cable (277), steel cable (277) other end then lies in the casing support top, the major control pivoted arm rotates maximum angle≤155 °, the transverse axis of narrow meshed a pair of pivoted arm and support transverse axis are on same horizon at this moment, and just pivoted arm stretches out ultimate range.

It is fixed by bolts to guard ring next door, casing support end face aperture.In the hand-hole time, loosen water pipe hoist engine and cable reel simultaneously and very make under the stake machine, then water pipe and cable also and then a stake machine go down, they have just spurred the triangle guide wheel, just overturn 155 °, just in time have two wire rope to haul this moment, and or else it can be rotated at once.So water pipe and cable dip to cylinder (279), change on the guide wheel of porose pivoted arm and roll.On cylinder (279),, increased the frictional force between them like this, can only slowly descend along with the stake machine then based on slip.When quarrel is unloaded in the lifting of stake machine, then to start water pipe hoist engine and cable whim, they are slowly rolled, below asynchronous, discuss again with steel cable.When the stake machine rose to the top, it had pushed up guide wheel, so whole triangle guide wheel will turn, narrow meshed a pair of pivoted arm just is poured on the sebific duct (280) of pull bar (275).Another guide wheel to pivoted arm plays supporting water pipe and cable, makes them follow a machine smoothly and transfers to the discharging tower and go to unload quarrel.Again in the hand-hole under the stake machine, repeat said process afterwards.

7, water pipe twist preventing apparatus preferred forms (Fig. 5 top): in stake machine top, bale handle (135) side fixes and use the good steel pipe (116) of steel plate (117) sealing in advance, and prune diameter approximately about half in top, but the top also keeps one section intact part, and weld a circle therein and fill in (118), go up with screw thread at circle plug (118) again and fix a twist preventing apparatus person in charge (119), be responsible on (119) and add two sealed bearings (122), the centre adds top tube (148), top adds round nut (124) and compresses, and adds packing ring (125) at its (124) end face.Bearing (122) outside puts a bearing cup (123), and to be on the safe side, the prevention bearing can destroy its sealing performance under the crunch of down-hole, thus added two sealing rings (120), and with gland (121) its (120) is compressed.Twist preventing apparatus is responsible for (119) top and is also added two a little bit smaller sealing rings (126), and (119) are responsible in the inaccurate sealing in its (126), and the while is sealed bearing cup (123) also.And then on bearing cup (123) top with the fixing drainage joint (149) of screw thread, and compress sealing ring (126) with its (149), the top adjunction is communicated with the pressure pipe that grows tall (150) on the face of land.Drainage joint (149) bottom is responsible for (119) top with the water pipe twist preventing apparatus and is not directly contacted.They are at least at a distance of more than 2mm, and this has just guaranteed that they do not disturb mutually.Be responsible between (119) bottom and the stake machine central tube drainage joint (114) and use short high-voltage tube (115) to connect, this has just formed complete cycling mechanism.No matter be that single top leads to the high-pressure water pipe rotation on the face of land or the stake machine rotation of bottom all solves by the friction of bearing and sealing ring.

8, bore enlarging aiguille preferred forms (Figure 15): get the bigger seamless pipe of thickness as central tube (291), and put an inside and outside hexagon steel pipe (292) at its outer wall, its internal diameter is general and central tube (291) external diameter is similar, its two ends space filling scolder.Central tube (291) bottom adjunction starter (1).Put a lower slider cover (293) in inside and outside hexagon steel pipe (292) lower end, it is cut out by the slightly bigger inside and outside hexagon steel pipe of diameter, can be free movable between them.In six planes of lower slider cover (293), wherein fin holder (294) is crept in three welding, and end fin free bearings (295) are expanded in three welding, and they are made after by the steel plate grooving.No matter creep into fin (296) and hinged three expansion end fins (297) with three of bolt respectively then on them, be to creep into fin (296) and expand end fin (297), and they all have tank, stud with 8 corner post alloys (298) simultaneously.There is an inside and outside hexagon to move seat (299) on the lower slider cover (293), can be fixed by bolts to inside and outside hexagon steel pipe (292) and goes up diverse location, so just can make expansion end fin (297) open different angles.At one section inside and outside hexagon steel pipe identical of inside and outside hexagon steel pipe (292) top welding, claim fixed cover with lower slider cover (293).Its outside is symmetrically welded three and goes up fixedly connected free bearings (301), and they should be corresponding with fin free bearing (295) at the bottom of the expansion of bottom.The processing of central tube (291) upper diameter is smaller, welds shoulder pad (302) and flange (303) then.Using connecting rod (300) that fin (297) is connected free bearing with last fixed cover at last is hinged together and just becomes one and bore enlarging aiguille.

Concrete course of action is as follows, connects conversion joint (304) earlier on the stake machine, again stake wing drill bit is fixed as contraction state.Hang in the guard ring of aperture boring enlarging aiguille then, and support its shoulder pads (302) with two square tubes.Just can couple together the flange of the flange of conversion joint and brill enlarging aiguille this moment with bolt.Outer-hexagonal moves the position of (299) in then adjusting as required, and tightens with screw, and other screwed holes are also used on the short screw bolt, in order to avoid from then on flushing liquor sprays.One place, bottom is that fin is in contraction state, and a middle place is that medium brill expands state, and its aperture is identical with stake machine aperture, top, and one place, top is wammel expansion state.At bottom slip cap (293), creep into fin holder (294), expand end fin free bearing (295), creep into fin (296) and expand under the weight effect of end fin (297), expand end fin (297) and be in contraction state.This moment just can bore enlarging aiguille together with stake machine time hand-hole at the bottom of.When beginning to creep into, starter (1) is bearing the top significant stress, so it is at first carved and gets rock and slowly sink in the stratum, in the decline of intracardiac pipe (291) and inside and outside hexagon steel pipe (292), driven last fixed cover connection free bearing (301) and also descended, it promotes connecting rod (300), thereby expansion end fin (297) is slowly opened, when opening up into to greatest extent, expand the decline synchronously of end fin (297) and starter (1) this moment.If reaming finishes, when promoting the stake machine and boring enlarging aiguille, under fin (297) at the bottom of the expansion of bottom and free bearing weight effects such as (295), expand end fin (297) and can shrink naturally again, at this moment just propose it outside the hole so long.This bore enlarging aiguille to creep into fin (296) and expand end fin (297) all be with bolt or hinged, can bore simultaneously and expand, also can unload one kind ofly, expands the end separately or creep into, but the aperture is smaller when creeping into separately.This bores enlarging aiguille can play positive and negative circulation.If long apart from creeping into or reaming, then as long as adjunction tube drilling rod (290) can reach purpose between enlarging aiguille top and conversion joint (304) bottom in boring.Tube drilling rod (290) also can be used as the conduit of concrete perfusion behind whole hole.

This bores enlarging aiguille can only follow reaming behind whole hole, can not carry out reaming in a certain location midway.For example when being lowered to sleeve pipe, run into big gravel midway, do not go under the sleeve pipe, this moment just must reaming.In order to address this problem, here in boring the tripod reaming hanging basket that the enlarging aiguille bottom increases a reversal of the natural order of things.Three hanging basket pin (284) are welded on the circumference of the short seamless pipe in center (285), and use the identical seamless pipe (286) of many bores of screw thread adjunction in its (285) lower end, and their length is decided by the position of required reaming and the distance at the bottom of the hole.Seamless pipe (286) lower end is a reaming starter of adjunction (287) also.In reaming, for ease of landwaste being discharged into the face of land with positive and negative round-robin method, also need unload guiding station head (1) this moment, several seamless pipe (288), (289) identical of adjunction in addition with central tube (291) bore, their length should exceed 310mm (this length difference of different bores) at least than the bottom surface of reaming starter, and (289) on the figure should be maximum reaming states.Only need during use three hanging basket pin (284) with bolt in creeping on the fin holder (294).After at the bottom of reaming starter (287) arrives the hole down, pipe (291) in the while center of rotation, then connecting rod (300) just promotes expansion end fin (297) under the significant stress effect of top, and continuous rock cutting (reaming).The reaming starter (287) of this moment does not have enough pressure though rotate, can not rock cutting.Have only after expansion end fin (297) opens up into to greatest extent, interior outer-hexagonal limit base (299) is pressed in expansion end fin free bearing (295) simultaneously and creeps on the fin holder (294), and intracardiac pipe (291) has been fallen 310mm in this moment.So expanding end fin (297) and reaming starter (287) creeps into synchronously.Cut down landwaste and be discharged into the face of land with positive and negative round-robin method.

The brill enlarging aiguille has been arranged here, as cooperated other mechanisms that following several drilling method also can be arranged, promptly had sleeve pipe (single or double-deck) to add the positive and negative circulation drilling method of brill enlarging aiguille.When with boring the method for grabbing to creep into the time or need in harder stratum, creep into.At this moment earlier the starter of main frame (1) is unloaded, change conversion joint (304), and then connect boring enlarging aiguille with bolt.When creeping into,, only need to connect and creep into into that fin (296) gets final product, but bore is little more with bolt if use independent drilling method then fairly simple.As require upper and lower footpath together also to be not difficult, and connect expanding end fin (297) with bolt equally, simultaneously interior outer-hexagonal limit base (299) centerlock, just at this moment can creep into, and meanwhile reaming, upper and lower footpath together.Available direct circulation or anti-round-robin method are discharged into sedimentation basin to landwaste.This drilling method is comparatively desirable, and segmentation has 12 kinds more than, but all similar, and it is wider to adapt to the stratum scope, and the rock following less than limestone hardness (comprising limestone) can both creep into, and rate of penetration is decided on the rock soft or hard.As be lowered to bilayer sleeve optimum operation at sea.

9, a tube two-in-one drill bit preferred forms (Figure 16) is taken out in impact: get a thicker seamless pipe as bit central pipe (310), in the circular bucket of cover lastblock bottom, its underpart steel plate (313), and welded, steel plate (313) symmetry is opened a subtriangular hole for 90 °, respectively be connected a valve base plate alive (321) that ratio 1/4 area of a circle is a little bit smaller four delthyriums bottoms with screw rod and splined nut then, a valve alive is installed above the every base plate (321).It is made up of the valve gap (322) of living, the valve bale handle (323) of living, the valve shaft cardiac skeleton (324) of living, the valve shaft cover (325) of living, the valve shaft heart (326) of living etc.Bucket bottom steel plate (313) is near central tube place welding four permeability cells (327), and it also passes valve base plate alive (321) simultaneously.In addition, also at its (313) outer rim welding truncated cone bucket (314), top also adds weldering cylinder bucket (315) simultaneously.At central tube (310) external diameter, welding cross steel plate (311) between four delthyriums of bucket bottom steel plate (313), this steel plate (311) middle and lower part cuts some, is just in time comprising bucket.Bottom longitudinally in its (311) cuts a straight trough simultaneously, for the usefulness of the iron chains long sword sheets of embedding (316), with several screw rods and channel nut (344) its (316) is fixed under the cross welding steel plate (311) (seeing amplification profile on the figure).Long sword sheet (316) bottom is driven cannelure again, and wherein continuous welding keeps flat rectangular tab alloy (317), grinds sword after the welding again on emery wheel.Be connected to steel plate in cross welding steel plate (311) both sides vertical welding on the plan, and short sword sheet also be installed in its underpart.Hole circle (312) is repaiied in one of cross welding steel plate (311) external diameter welding, and its underpart is welded with column alloy (2).In addition, also wear a hole in the outside, middle part, a slag stopper circle (329) of being made by round steel is worn in the centre, and is welded.Mainly in order to reinforce cross welding steel plate (311) and welding slag stopper (330).Four slag stoppers (330) are cut out by the truncated cone.A drill bit (318) is installed in central tube (310) lower end, and the bottom is welded with recessed sword sheet (319) and fovea superior sword sheet (320).Sword sheet bottom is welded with equally and keeps flat rectangular tab alloy (317).The effect of its (318) has two, and the one, make guiding and use; The 2nd, in the time of with anti-circulation hole flushing, its (318) is one and inhales quarrel mouthful.But this drill bit (318) only is applicable to softer stratum and creeps into.As will in hard base rock, creeping into, then only need change a nothing and rein in the stub drill (342) of bone and get final product, make it the sword sheet and the long sword sheet of cross (316) on same horizon.Central tube (310) top adds a reducer union (331).Be symmetrically welded a pair of bale handle post (332) on cross welding steel plate (311) top, a crossbeam (135) is installed on it, middle with impact elevator of screw shaft cross-under.It mainly is made up of elevator elevator (333), pull bar (344), the oval drop handle plate of small washer (335) (336), drop handle (337), spring (338), round nut (339), large washer (340), special thin nut (341) etc.Increase the weight of round steel (328) in 4 of central tube (310) top external diameter welding more at last.

Concrete action is as follows: when twisting with suitable, when steel cable lifting elevator drop handle (337) is twisted on a left side, spring (338) is compressed, force oval drop handle plate (336) to rise, at last by round nut " dieback ", so whole dash taken out drill bit and is raised, after rising to certain altitude, loosen the hoisting mechanism hand very, this moment, drill bit descended rapidly, the volume of flushing liquor and useless quarrel is also splashed bloated rapidly, this moment, they have to rise along three approach, the one, permeability cell (327), the 2nd, bucket and repair following big between the hole circle (312) and little annulus (middle separated) by cross welding steel plate (311), the 3rd, the valve gap (322) of living is forced and is opened, and from then on flushing liquor and useless quarrel directly enter bucket.After being subjected to action of gravity and top slag stopper (330) at last, increasing the weight of the stopping of round steel (328), their change direction and fall in the bucket rapidly.The valve gap (322) of living this moment also descends automatically and seals.Dash take out under the drill bit at the bottom of the hole after, loosen steel cable, so oval drop handle plate (336) and drop handle (337) turn over certain angle automatically.Then towards take out drill bit just again turn over certain angle when promoting steel cable again next time.After impacting repeatedly, when useless quarrel had certain quantity in the bucket, if valve gap (322) relation of can not being opened of living is also little, they can also enter from annulus and permeability cell (327).After bucket is filled, it is carried toward ground, be placed on the special device, valve gap (322) is backed down and is unloaded useless quarrel, and left available water is rinsed well.After boring finishes,, receive the pressure pipe (150) of growing tall in the reducer union (331) earlier, with direct circulation or anti-the circulation during hole flushing as needs simultaneously in order to prevent drill bit in decline, can rotate, may make water pipe be rolled onto wire rope and get on, preferably change and have generally creeping into of bearing and use elevator.Creeping into also available the method midway comes at the bottom of the cleaning eye.This drill bit also has characteristics, can lift down processing at any time behind the sword sheet blunt.

Use in order to be engaged in the bilayer sleeve, the bore of drill bit is taken out in supporting here dashing should be than the little one-level of main frame bore, promptly also smaller than the internal diameter of the gathering sill of inner sleeve.Can not influence its independent use.

Had to impact and taken out the two-in-one drill bit of tube, as cooperated other mechanisms that following several drilling method also can be arranged, promptly had sleeve pipe (single or double-deck) to add towards taking out the positive and negative circulation drilling method of drill bit.If will be loose sandy soil layer, bottom on top when constructing in than competent bed, and main frame (dash and grab brill) can not be dealt with.Top can be bored method with individual layer or bilayer sleeve and crept into this moment.And the bottom can be changed the impact of this patent design of little one-level and takes out the two-in-one drill bit of tube and carry out positive and negative round-robin method and creep into.After reaching projected depth and requiring, during as the hard reaming again of all too, promptly stop to creep into.Allowing as formation condition just should reaming (up and down with footpath or expansion).Only need this moment the brill enlarging aiguille of this patent transformation is received on the main frame, creep into and to achieve the goal with direct circulation or anti-round-robin method equally.

10, hand or electronic water pipe hoist engine preferred forms (Figure 17): it is made up of several major parts such as support, reel, transmission mechanism and suction, gutter rotation-preventing mechanisms.Support is composed as follows.The steel plate (355) of getting two thicker broads is welded on the base plate (356) next door reinforcement of weld angle bar (374).Support steel plate (355) two middle side parts are respectively opened a screwed hole, use for bearing cup (365) is installed.Two of welded top are steel pipe (357) fixedly, also can be used as bale handle and uses.Reel composed as follows.Get a thicker seamless pipe and be cut into two sections, and process internal and external screw thread; The left side is the axis person in charge (358) for one section; The right is axis row, water inlet pipe (359) for one section, and in cutting a breach near male thread one end-grain cutting, simultaneously internal diameter is widened, then in the copper pipe or the seamless pipe (371) of one section bending of this welding.In addition, be responsible for the suitable seamless pipe of (358) middle part cover the preceding paragraph internal diameter at axis, be axis sleeve (360), and respectively weld a circular baffle plate (361) that diameter is identical in sleeve (360) two ends, its (361) between be symmetrically welded eight fixing little steel pipes (362).In order to strengthen drum diameter and to alleviate its weight, be symmetrically welded eight (or 12) in plate washer (361) outer rim and widen little steel pipe (363).And a circular hole is opened in the appropriate location on the close baffle plate (361) of bend pipe (371) in the right.Reel is fixed in axis with key (370) to be responsible on (358).After axis is responsible for (358) and row, water inlet pipe (359) are connected, be fixed on the support steel plate (355) with bearing (364) and bearing cup (365).

At row, water inlet pipe (359) right-hand member a rotation-preventing mechanism is installed, the water pipe anti-rotation device on its fundamental sum stake machine top is identical.Here different is the no sealing ring in bearing (122) bottom, so cause bearing cup (372) short, what while and drainage joint (149) joined is not the pressure pipe (150) that grows tall, but lead to suction, the gutter (373) in pond, other are to the greatest extent identical, seldom give unnecessary details here.Transmission mechanism is installed in support steel plate (355) left side, opens a screwed hole earlier in its underpart, for rigid bearing cup (378) usefulness, uses gearcases of welding such as steel plate (375), (376) then, wherein has a side to seal without steel plate, is convenient to gear and installs.Open a big hole in the middle and upper part of gearcase left side welding steel (375) again, it is equally big to be equivalent to driving gear (366) diameter at least.Be equivalent to the position in support steel plate (355) lower thread hole then in its underpart, open a screwed hole again.In gearcase, be responsible for (358) in axis and go up with key fixedly driving gear (366), fixed triangle belt pulley (368) outside it again.In addition, also with bearing (377) and bearing cup (378) driven gear central axis (379) is fixed up in the gearcase bottom.In box, fix driven steamboat (367) then with key (380); Box external fixation band triangular groove friction wheel (382), fixing bicycle pin arm (381) again in the outer end.Under band triangular groove friction wheel (382), lay an activity wedge shape friction wooden unit (383) on the support base plate (356).

Concrete course of action is as follows.In this design, an assistance platform (here not accompanying drawing, do not belong to patent partly) is equipped with in chuck and casing support seat next door, their height and size are basic identical.The motor of on assistance platform, laying water pipe hoist engine, cable reel, hydraulic pump and matching etc.Wherein with water pipe hoist engine volume maximum.Earlier suction, gutter (373) are terminated on the drainage joint (149), and tighten with band before using; The other end is received pump and is inhaled---spray on the anti-cycling mechanism, after lead to the pond again.Then the head of the pressure pipe of growing tall (150) is passed the circular hole of reel baffle plate (361), receive again on the crooked seamless pipe (371), and also tighten with pricking.With motor or hand method high-voltage tube (150) is rolled onto on the reel then; Afterbody is received on the drainage joint (149) of a machine water pipe twist preventing apparatus, also uses band institute tight.At last wedge shape friction wooden unit (383) is adjusted, made between its (383) and the friction wheel (382) only to have some friction.This moment can be in the hand-hole under the stake machine, as long as it spurs gently, high-voltage tube (150) just can be followed down automatically.When will promote machine, earlier wedge shape friction wooden unit (383) is unclamped.Through the electric current input motor after the frequency conversion, the speed that high-voltage tube (150) is risen is slightly larger than the steel cable rate of climb, goes artificial control with the wooden unit (383) that rubs then then, and the rate of climb that makes them about equally.After the stake machine was mentioned the aperture, if transfer to the discharging tower to it goes to unload quarrel, then high-voltage tube (150) also and then in the past.Repeat said process afterwards.Here the thing of cable is not mentioned, and mainly is the cable reel with forefathers.

11, manpower folding and unfolding water pipe platform preferred forms (Figure 11): get two blocks of 10mm steel plates, it is processed into Long Circle, lower bolster (217) is in one of bottom; Backing plate (218) is called on one on top, also processes several holes in this, middle big cubic hole, and two ends are half garden and process some big slightly holes, garden.These two kinds of holes all are for the usefulness of leaking.In addition, be half garden processing double-layer aperture in two ends again, use for welding railing (219).Lower bolster (217) bottom welding four suspension columns (216).

Concrete course of action is as follows, the pressure pipe (150) of growing tall is terminated to pump inhales one and spray on the anti-cycling mechanism, after again towards the pond.Then its (150) is figure of eight volume and is placed on the platform, remainder is received on the drainage joint (149) of a machine top twist preventing apparatus.The ascending, descending of high-voltage tube later on all needs human control.

12, discharging tower funnel lower cylinder switch preferred forms (Figure 18): get two short seamless pipe (391), (392) that diameter is bigger, central cut-out half (cutting 392) wherein more, two ends stay small part, and fill in (397) with circle and weld, Here it is so-called cylinder, right cylinder (391) is fixed long axle (400) with key (402), and the tube (392) that rolls left is then fixed short axle (403).And then at two axles (400), (403) same end each fixes a roller gear (401), make their reference diameter identical with diameter of cylinder.Two axles (400), (403) use bearing (398) to be fixed on the welding medium plate (396) respectively.Cylinder top respectively is fixed with a mud brush (393) in the opening both sides with bolt, and the wearing and tearing back is replaceable.Secondly, fix long drive link (404) on the suspension column of discharging tower, its (404) one end is enclosed within the inside and outside hexagonal cover of welding (399) of right drum shaft (400), can forward and backwardly move a certain distance; The other end is fixed a steering wheel (410), and also fixes a bicycle flywheel (412) with screw thread in the right side.Its (410) can only be rotated by clockwise direction generally speaking, and the crack just appears in the then counter-clockwise direction rotation of tube (392) of rolling left when forwarding the part that is cut to, switch opens, if it is relative and orthogonal to forward two tangent planes to, switch reaches to greatest extent.This moment as rotation continuously again, switch slowly diminishes again, until closing, in case of necessity, if right cylinder (391) counter-clockwise direction is rotated, then spur drive link (404), flywheel (412) just can leave the staple of catheter head welding disk (409), and how reversing subsequently can.Only need on the steel plate of funnel bottom, get final product during use with bolt.

Claims (10)

1. it is as follows to dash the technical characterictic of grabbing brill stake machine: 1) dynamic characteristic.Because of the fin drill bit open and the gathering process in all be slowly to cut the rock stratum, rate of penetration is slower, so required power is less.The design only uses the small size motor of two 7KW, increases a closed chamber and two 7KW small size motors inadequately again as power.Here do not establish gear, mainly utilize the modern high technology product---frequency converter is realized the speed change of motor, and is much more flexible like this, and different rock-layers can be crept into different rotating speeds.2) transmit the torsion feature.This machine without power head does not more have drilling rod, is played by steel cable, and lifting freely like this.Mainly utilize the gathering sill of inner sleeve to be used as the reaction torque balanced controls, promptly drilling rod and sleeve pipe are combined together, inner sleeve can also feed usefulness as drilling rod in case of necessity.3) structural feature.The opening of fin drill bit, locking mechanism are different from the tradition grab bucket, with rope or hydraulic-driven.Because of it rotates, hydraulic pump is placed on the face of land or the down-hole is all inconvenient.And utilize lever principle here dexterously, connecting rod (8) lower end is articulated on the Connection Block (14) of fin drill bit, and the not direct and following cross recess weldment in upper end (7) is hinged, and cross recess has upwards lifting slightly like this, the fin drill bit just can leave at the bottom of the hole, grabs less than landwaste.Here it is articulated in lever crossbeam (9) middle part, lever crossbeam (9) one ends are articulated in down on the cross recess weldment (7), and the other end is articulated in suspension rod (10) lower end.Suspension rod (10) upper end is articulated on the gooseneck bracket (11) of hanging garden tube (22) top.The fin drill bit has four, and every is cut into different trapezoidally again by three 10mm steel plates, weld just to become after bending again.The bottom edge of a knife is a quick-wear part, for ease of welding alloy sheet or surfacing alloyed powder, so processing in addition connects with bolt.Middle and lower part, the drill bit back side is welded with three wedge-likes wear-resisting (geology is used) steel disc, all has horizontal tank by certain distance.Edge of a knife bottom does not need to weld steel disc, directly processes from skin.It is more that right side weldment (29) protrudes flap edges, sees from vertical and horizontal direction all to be wedge-like, the tangential rock stratum of its scarf.And on its edge the alloy sheet (2) or the surfacing alloyed powder of vertical welding some.Intermediate weldment (18), vertical direction see and are wedge-like that horizontal direction is seen as rectangle, is welded with alloy sheet (2) or surfacing alloyed powder on the inclined-plane, the outside equally.Left side weldment (30) does not have cocked bead, and is consistent with the outer sideline of fin, sees from vertical and horizontal direction to be wedge-like yet, and its scarf slopes inwardly, at this iron chains seam gold plaque (2) not, but should be at some alloyed powders of surface spraying weld.For guaranteeing that the fin drill bit also can rock cutting when the counter-rotating, also iron chains weldering some alloy sheets (2) or surfacing alloyed powder on the layer edge within it.The following cross recess weldment (7) of this machine itself is just long, so the twisting resistance of connecting rod (8) is just bigger.Because there is special structure in it, when the fin drill bit when opening, also promptly load when constantly increasing, following cross recess weldment (7) is also and then descending, and removes to offset the part load that connecting rod (8) increases.

This machine is when work, and the frictional force of the interior hexagonal axle sleeve (37) that central shaft tube is connected with the garden tube of hanging is very big, can directly influence its upper and lower activity.Be head it off, in this, add 3 steel balls in each plane of hexagonal cover here, it is directly contacted with the plane of center hexagonal axis, so just significantly reduced the frictional force between them, make the central shaft tube activity freely.Secondly, open at fin, when closing, the frictional force of connecting rod (8) and following cross recess weldment is also very big, influences its vertically and horizontal movement.Here be head it off, in using a fixed frame of bolt (32) outside cross recess weldment (7) lower end down, both sides respectively are equipped with a cylinder (34) with thick bolt dress in the frame, connecting rod (8) is directly contacted with cylinder (34), significantly reduced the frictional force between them like this, made connecting rod (8) activity freely.4) the fin drill bit opens, closes feature.When motor drives central shaft tube clockwise direction rotated, the bottom was rotated partly and is and then rotated, and the fin drill bit still is closure state during beginning.Lead bit (1) does not rotate under the significant stress effect partly on top, at first carve and get the rock stratum, force central shaft tube to descend, thereby make down cross recess weldment (7) also be with lever crossbeam (9) one ends to descend, oppress the fin drill bit by connecting rod (8), it is slowly opened.Lever crossbeam (9) reaction force that the other end produced promotes to hang garden tube (22) by suspension rod (10), necessarily alleviates its weight on the degree of being, and makes the fin drill bit be easier to open.Central shaft tube constantly descends, and connecting rod (8) constantly promotes the fin drill bit and expands outwardly.This moment, the alloy sheet (2) of its right weldment (29) began to cut the rock stratum, and constantly landwaste was dialled the center of moving.Can see from face of land depth gauge, when the stake machine after falling at the bottom of the hole, as falling 180mm (this degree of depth difference of different bores again, and creep into for the first time and should bore some more) then fin opened up into to greatest extent, this moment, it was outward-dipping a bit, but its outside the right side (29), in (18), a left side (30) weldment be vertical, so the hole that gets out also should be vertical.But be not flat at the bottom of the hole, it is along the open track rock cutting of fin, can describe with simple image, and some picture " volcanic cone " slowly swells to the centre from hole wall, and there is individual hole at the center.Should bore this moment more, and hole wall is repaiied the garden.

In the time of the counter rotation of central axis pipe, the fin drill bit also and then rotates in succession.Because the effect of the weldment (30) on its left side and the existence of medium (residual quarrel), just can produce and a kind ofly make pressure that its inwardly shrinks, it is closed disturb but differ.The fin drill bit that only reverses on one side, on electronic scale control weight (top do not rotate partly, or more bigger) and on depth gauge be controlled at the scope of 180mm in slowly promote machine on one side.At this moment connecting rod (8) just produces the active force to in-draw to the fin drill bit.But the suffered pressure of fin drill bit does not only reduce, and has increased some on the contrary.Unite in this two power and to do to have down, it does not leave at the bottom of the hole all the time, on one side but be lonely wire and shrink, with alloy sheet (2) cutting " volcanic cone " protrusion part of its internal layer institute iron chains, cut down landwaste and constantly be involved in the center on one side by skin.If softer sand layer, in this two power effect next grab just can be loose.After the stake machine was increased to 180mm, the fin drill bit closed up fully." volcanic cone " that protrude this moment almost scabbled, and this has just finished the native process of grabbing.If continue to promote a stake machine again, just it can leave at the bottom of the hole, outside proposing the hole.5) on above-mentioned principle basis, can design the stake machine of different bores as required.Minimum should be about φ 800-φ 900mm, and maximum can be greater than φ 3000mm.Because of bore too small can not load motor in the closed chamber; The too short unfavorable fin drill bit of lever crossbeam (9) is opened and is closed.Big more being easy to more of bore designed, can be being placed in the closed chamber than high power motor.

2. the distinctive inside and outside sleeve pipe of this machine: the technical characterictic of 1/ movable inner sleeve is as follows: 1//the design breaks the normal procedure, the reaction torque balanced controls are made in the gathering sill (162) of utilization activity inner sleeve, (174), drilling rod and sleeve pipe are combined together, as not needing cased place to creep into, then use distinctive the dashing of this patent instead and take out drill bit.The effective steel sheet of 2//cover is made, and need not weld, and only welds a pair of special switching and connects and buckle opening and closing line (171) upper and lower part, has circular hole in the middle of it, forms with a little water pipe cross-under.And on the left of connecing button, open a slot, for connecing the usefulness that deduct contracts.3//except paired special the connecing outside the button of abutment line (171) welding, the place that is similar to cross symmetry with its also is welded with the single button (161) that connects, and also cross-under has little water pipe therebetween.Its effect one is the torsion between balancing sleeve, the 2nd, and little water pipe can be connected with top high-pressure hydraulic pump (geology is used), but flushing liquor direct projection bottom hole wall improves drilling efficiency.4//split in the sleeve pipe middle part in order to prevent closed line (171), so shrink nail (164) two pairs of the appropriate location, both sides of its (171) welding, every nail has an aperture, behind every pair of binding iron wire, near passing aperture extraction tube outer wall, again it is tightened, link up with iron wire again between every pair and the every joint sleeve pipe then.5//sleeve outer wall is symmetrical hexagon welding six muscle sheets (167), and appropriate location, every muscle sheet upper and lower has three kinds of transverse grooves.A kind of for sleeve engages and hang own wt and use; The another kind of chuck that supplies twists and hangs usefulness; The transverse groove of side exists only in muscle sheet top, for putting forward the usefulness that frame is hung.In addition, the middle part of every muscle sheet has a Long Circle hole, and passes sleeve pipe, shrinks the usefulness of post-tensioning hook block extension for sleeve pipe.

The technical characterictic of 2/ fixed jacket pipe is as follows: be welded after rolling by the steel plate slightly thicker than movable inner sleeve again.All there is the length of 50mm every joint sleeve pipe upper and lower as overlap partly (down except the joint bottom).Casing inner diameter is than the big 4-6mm of movable inner sleeve muscle sheet external diameter, and outer wall is welded with six muscle sheets equally, and its thickness, size and the transverse groove opened be consistent with movable inner sleeve all.Slotted hole is not opened at the middle part only.All be used generally speaking with inner sleeve.For inside and outside sleeve pipe is fused, increase its anti-twisting property, should descend the inwall of joint most, just be equivalent to the position of the projection (180) that inner sleeve descends joint muscle sheet most in outer tube, respectively weld a gathering sill in its both sides with the book steel plate, projection (180) is embedded in wherein.The upper and lower activity in an adjusting range of inside and outside sleeve pipe is no problem.

3. the technology of chuck is special as follows: 1/ mainly utilizes the horizontal telescopic process of chuck case movable block (201) to tighten or the muscle sheet of the inside and outside sleeve pipe that gets loose.Be easy to after the wearing and tearing change.2/ chuck case is welded between the circular clamping plate of internal layer (204), and its right side, outer end is welded with a pressure coil (212), turns left and right 19 ° as the cover upward pressure can promoting the circular clamping plate of internal layer (204), and purpose is in order to engage or to separate inside and outside sleeve pipe.3/ whole chuck is connected on 4 conduits (209) of casing support, can do upper and lower moving, and balanced action is arranged again.4/ the design divides three place's chuck for installing on casing support, one place, bottom is welded together by two single deck tape-recorder dishes, is fixed on the axle of telescoping cylinder (226), except that engaging or separate the inside and outside sleeve pipe, also can depress or rise group internal and external casing simultaneously.A middle place is also welded together by two single deck tape-recorder dishes, but it hangs telescoping cylinder (228) axle (comparable bottom oil cylinder is smaller) down, and mainly engage or separate inside and outside sleeve pipe with it, but its depressing or pulling out booster action is also arranged sleeve pipe.One place, top is single chuck (229), is fixed on the stent cover by big nut (230).Be lowered in the short time of bilayer sleeve, all chucks of bottom (225) all will get loose, and this moment, inside and outside sleeve pipe total weight was worked to hang in its (229).As long as 5/ in the position of rectangle welded pipe (205), the hole of inside and outside layer circular clamping plate (204), (208) is aligned after, add a latch (210) chuck is maintained static.

4. it is as follows that sleeve pipe is carried the technical characterictic of frame: design for hanging inside and outside sleeve pipe specially, be welded with six muscle sheets because of their outer wall all is symmetrical hexagon, the upper side appropriate location all has transverse groove.So, be the center with axis (190), on last disk (192) face, be and be symmetrically welded six and carry set a roof beam in place (191), be radial, hook (194) in the cross-under of outer end, its underpart is worn a hook annulus (195) again.In annulus (195), wear one and can draw the heavy loop chain (254) of 5-6 ton,, do not draw among the figure because of compiling width of cloth relation.2.5 times of loop chain (254) length 〉=casing length.And then wear one again in the bottom of its (254) and link up with annulus (195).Other gets a thicker steel plate, and top is pared down a bit more a little, and wears a hole; The bottom opposite side is also pared down a bit more, but the bottom stays two nails; Side is also pruned partly, but the bottom stays two shoulders, and this is down clothes-hook (196), and puts a rectangular sleeve that is cut out by rectangular tube (197) therein, then following clothes-hook (196) is enclosed within the hook annulus (195).At last axis (190) is enclosed within on the elevator that generally creeps into usefulness, can carries out the operation of lifting sleeve pipe.

5. the technical characterictic of aperture guard ring and inner sleeve drag hook is as follows: 1/ aperture guard ring: mainly some fore-sets of welding (235) form between upper and lower two blocks of circular steel plates (239), (234).Fore-set (235) middle and lower part welding two reinforcing steel rings (236).The inboard symmetry of top annulus (239) is opened six small gaps, and at a ring beam of being made by round steel of its surface soldered (241), also puts on a hook annulus (195) in indentation, there, so that hang loop chain (254).The design's that Here it is purpose.2/ inner sleeve drag hook: hang a medium plate (238) with loop chain (254), a band of its middle and lower part welding externally threaded steel pipe of double end (248), pass an axle (247) in the pipe, its (247) one end is fixed a drag hook baffle plate (249) with key, the other end adds a radially little bearing (251), and compresses with round nut (252).By the cooperation of bearing (251), axle (247) and band double end riffled tube (250) are coupled together at last.The rotation of axle (247) and the rotation of double end riffled tube (250) are not disturbed mutually.For ease of operation, in round nut (252) outer rim welding hoof ring (253).Such drag hook can arbitrarily be swung and rotate.

6. the technical characterictic of water pipe and cable saddle is as follows: 1/ gets two less round plates (261), its edge welding three stationary pipes (263), be symmetrically welded three block plates on two terminal circle steel plate (261) circumference---guide wheel pivoted arm (262), and between three pairs of pivoted arms, weld a stationary pipes (263) respectively again.This has just constituted the triangle guide wheel, but its turning cylinder is or not the guide wheel center, and on fulcrum of guide wheel.This structure is convenient to the upset of whole guide wheel, does not influence the lifting of a machine.2/ respectively installs a transverse axis (264) in two pairs of pivoted arms (262) outer end, and there is radially little bearing (266) at two ends, by threaded bearing gland (267) it are fixed on the pivoted arm (262).Be installed with three circular baffle plate (265) on the transverse axis (264), the centre with different length collar (269) separately.In order to prevent moving of baffle plate (265), between its (265) and bearing (266), also has a little collar (268).3/ in order to support whole triangle guide wheel, so a support must be arranged.Go up two the short forward foot in a step (271) and two long rear feet (270) that cut out by steel plate of welding at base plate (273), the forward foot in a step (271) is wideer than the rear foot (270).Support two upper lateral parts and middle part Welding flat steel (274) are reinforced; Front and back then welded steel pipe (272) reinforce.A pull bar (275) is fixed with nut (276) in the rear foot (270) top, and one section cylinder (279) is worn at its middle part, and one section sebific duct (280) is respectively worn at two ends.The forward foot in a step (271) top two sides are respectively opened a screwed hole.4/ respectively opens a circular hole in another relevant position to pivoted arm (262) outer end, wherein pass an a little longer transverse axis (264) equally, two ends are equipped with journal bearing (266) equally, but not on pivoted arm (262), but be fixed on the screwed hole of the support forward foot in a step (271) with bearing gland (267).For ease of guiding, between pivoted arm (262), add slightly bigger collar (269); Between bearing (266) and pivoted arm (262), add a little bit smaller slightly collar (268); In addition, also between the pivoted arm (262) and the support forward foot in a step (271), add large washer (278).5/ in selecting the appropriate location respectively to bore a hole near the downside of a pair of pivoted arm of the rear foot (270), and be a little wire rope (277).

7. the technical characterictic that bores enlarging aiguille is as follows: after 1/ brill enlarging aiguille top must connect conversion joint (304), just be used with the stake machine, can play positive and negative circulation and creep into.2/ with forefathers' brill enlarging aiguille some is different, forefathers' lower hinge partly maintains static, upper articulation then is movable partly.The design is just in time opposite with forefathers', fixing upper articulation seat, and make the activity of lower hinge seat.In boring the expansion process, starter (1) is under the significant stress effect of top, it is at first carved and gets the rock stratum, thereby the inside and outside hexagon steel pipe (292) of intracardiac pipe (291) in being welded on is and then descended, also driven last connection free bearing (301) and descended, slowly opened so connecting rod (300) promotes to expand end fin (297).When predetermined fixed at the limit base (299) on the inside and outside hexagon steel pipe (292) during to free bearing (295) down, fin (297) is flared to greatest extent, this moment starter (1) and expand the synchronous decline of end fin (297).The starter here (1) is at first carved and is got the rock stratum following purposes is arranged: the one, and positioning action; The 2nd, favourable residual quarrel concentrates on starter when playing reverse circulation drilling.3/ lower slider cover (293) also is the hexagon steel pipe, and its surface is symmetrically welded three river bottom protection fin free bearings (295) and three and creeps into fin holder (294).Can install separately and expand end fin (297) or creep into fin (296), but also the two is installed simultaneously, just can expand the end separately or creep into, also can creep into simultaneously and reaming.4/ if long distance is crept into, and needn't be lowered to sleeve pipe again, then only need can reach purpose by adjunction tube drilling rod (290) between brill enlarging aiguille top and conversion joint (304) bottom.Can be used as the conduit of concrete perfusion behind the whole hole of this tube drilling rod again.5/ in order to solve in a certain location reaming problem midway, increases a tripod reaming hanging basket boring the enlarging aiguille bottom here.During use its three pin (284) are reversed with bolt in creeping on the fin holder (294).Bottom screw thread adjunction reaming starter (287).During reaming, does not creep into its (287) in beginning, has only that they just creep into synchronously when expansion end fin (297) opens up into to greatest extent.Available positive and negative round-robin method is discharged into the face of land to landwaste.

8. it is as follows to impact the technical characterictic take out the two-in-one drill bit of tube: 1/ forefathers are drill hammer and take out tube as two boring means independently, and here the two are combined as a whole, and a bucket is installed on drill hammer top, and the bucket bottom is installed four valves alive in addition.When drill bit descends rapidly, the volume of flushing liquor and useless quarrel is splashed bloated rapidly, this moment, they have to rise along three approach, the one, permeability cell (327), the 2nd, bucket and repair following big between the hole circle (312) and little annulus, the 3rd, the valve gap (322) of living is forced and is opened, and from then on flushing liquor and useless quarrel directly enter bucket.After action of gravity and being subjected to the stopping of top slag stopper (330), their change direction and fall in the bucket rapidly at last.The valve gap (322) of living this moment also descends automatically and seals.2/ to be that long sword sheet (316) or short sword sheet (cannot see among the figure) are all made movable, is fixed in steel plate (311) groove with bolt (344).Sword sheet (316) bottom has cannelure again, and wherein continuous welding keeps flat rectangular tab alloy (317), and then grinds sword on emery wheel.With lifting down processing after blunt again.3/ central tube (310) is design long drill bit (318) and stub drill (342) down, the mainly convenient positive and negative circulation hole flushing of whole Kong Houyong.Long drill bit (318) band is reined in bone, and creep on suitable softer stratum, does the usefulness of guiding.Stub drill (342) is not with and is reined in bone and long sword sheet (316) at grade, and suitable hard base rock creeps into.Hole circle (312) is repaiied in one of 4/ cross steel plate (311) cylindrical welding, and the bottom is welded with column alloy sheet (2), for the usefulness of finishing, protection hole wall and guiding.5/ valve of living directly is not fixed on the bucket base plate, and inconvenience repairing like this is fixed on it on the other valve base plate alive (321) but be divided into four, is fixed by bolts to then on the bucket base plate (313), can lift down repairing at any time like this.6/ in percussion drilling spreading high-voltage tube (150) not, the sealing of reducer union (331) applied screw cap.Connect the pressure pipe of growing tall (150), available positive and negative circulation hole flushing behind the whole hole.

9. the technical characterictic of hand or electronic water pipe hoist engine is as follows: 1/ purpose of design is mainly for ameliorate body power labour intensity.When the stake machine when slowly descending, high-voltage tube (150) also and then descends certainly.But in order to reach synchronous purpose, control by the friction of adjusting wedge shape friction wooden unit (383) and band triangular groove friction wheel (382) here, this friction should be to make a machine spur high-voltage tube (150) gently just can follow down automatically.When will slowly promote machine, earlier wedge shape friction wooden unit (383) is unclamped, then motor through the input of the electric current after frequency conversion drive hoist engine, can make the rate of climb of high-voltage tube (150) be slightly larger than the steel cable rate of climb, use friction wooden unit (383) to go artificial control then, the rate of climb that makes them about equally.2/ the design the right has added a water pipe twist preventing apparatus, can guarantee flushing liquor and useless quarrel continuous the conveying or aspiration procedure in high-voltage tube (150).Particularly when direct circulation is crept into, use this hoist engine very convenient.But when being used in reverse circulation drilling, a large amount of sand, stone and flushing liquor flow in swan-neck for a long time, and whether clogging is arranged, and just know through further practice.3/ the design has increased a hand-operated mechanism, is not to fall behind, but can inoperative motor when in short distance, promoting high-voltage tube (150), use hand solution simply.Just in case high-voltage tube (150) is following too soon sometimes, have little time very system again, catch pin arm (381) just can deal with problems this moment.

10. the technical characterictic of discharging tower funnel lower cylinder switch is as follows: 1/ the design cuts in the middle of it half to two short garden tubes (cylinder) (391), (392), two ends stay few part, and welding garden plug (397), an axle (400), (403) are respectively worn in the centre, and in a side of axle each is fixed one and makes the calibration garden diameter garden stud wheel (401) identical with the cylinder external diameter, they should intermesh.2/ as making right side gear (401) do the clockwise direction rotation, does to roll relatively in garden tube (cylinder) (391), (392) that then also can drive on the same separately axle.Crack, switch opens just appear when they forward the part that is cut to.If forward the relative and switch opens maximum then when orthogonal of two tangent planes to.Afterwards, rotate then as also continuing clockwise direction that switch slowly diminishes again, have only when tube surface, two gardens contacts with each other, switch cuts out fully.3/ as long as right side gear keeps clockwise direction to rotate forever, and then cylinder (391), (392) are always opening movement upwards and has an active force that upwards promotes, so no matter what stone top have also do not stop their rotation.But switch is when beginning to cut out, and resistance that cylinder (391), (392) are subjected to can be big, thus the time a large amount of stones can drop in the half of garden tube.Here unique solution is to excise some in tube (392) bottom of rolling left more, causes in rotation their edge height inconsistent, makes some landwaste be easy to swing to the left side, is unlikely " stuck " cylinder.4/ left side (392), right (391) cylinder top have " mud brush " (393) with bolt, and the wearing and tearing back is replaceable, keeps its sealing.
