Abstract
The invention discloses a guide ring cap for threading during pipe distribution and a threading method for the guide ring cap. A plurality of clamping slots are uniformly formed on the inner circumferential surface of the guide ring cap along the circumference; guide wheels are arranged in the clamping slots; and the rolling surfaces of the guide wheels protrude from the top surface of the guide ring cap. By a wire-feeding guide ring for threading during pipe distribution, resistance formed by feeding of a wire cable at a pipe opening is reduced greatly; therefore, the wire-feeding speed is increased greatly and a wire cable skin coating layer can be relatively protected to a certain extent, even the possibility that the conventional threading construction required to be finished by two persons is changed into the threading construction finished by only one person is increased.
Description
Technical field
The present invention relates to threading construction in Sunken wire tube, be specifically a kind of in stringing threading line sending guide ring and utilize guide ring to carry out the method for threading.
Background technology
The fast development of China's informationization technology, makes family and society significantly increase the demand of the kind of various logical line cables and quantity.Thereby, in construction, usually need to a large amount of installation pipe cloth be embedded in various building structure in the civil engineering stage, when entering electric finishing operation, in spool, penetrate again various cables in the future.Concrete grammar during threading cable is: by one end of the lead-in wire at break-through spool origin or beginning place with treat that one end of threading cable is connected firmly, then, the other end that is leading lead-in wire from spool end is tractive firmly outwards, along with end leads is constantly pulled out, origin or beginning lead-in wire just enters spool with cable, until cable connects whole piece spool.
In current practice of construction process, construction method is all by people tractive steel wire endways, another person coordinates line sending in origin or beginning, this be because spool together with pipe storehouse conventionally on body of wall in a certain locus, the mouth of pipe is conventionally all upright, the cable that does not enter spool is generally all placed on the ground, cable and mouth of pipe section form and are bordering on right-angle relationship, if no one's line sending, spool mouth will be hung and draw cable, cause inlet wire difficulty, even can not inlet wire, continuing inlet wire must make the coarse mouth of pipe cause obvious scuffing to cable, so lead the construction of logical cable tradition, generally all to there be two people.In practice, the reason that this work is wasted time and energy, only because tractive effort, is also that line sending needs one to save and send, and has sent a joint to stop, and then prepares to be ready to, then carries out threading, until cable connects whole spools.
In stringing, penetrating cable, is mainly to adopt two kinds of methods at present, and the first is a reserved steel wire or iron wire in spool, in the civil engineering stage, spool and steel wire is together imbedded.At electric decoration stage, use reserved steel wire traction cable break-through spool.Its shortcoming is: waste steel and construction effort, effect is not good enough.The general likely several years even longer time of interval from pipe laying to threading cable, limited by cost, generally reserve not high getting rusty easily of wire quality, reduce tensile strength, so steel wire reserved in pipe generally can not be too thin, gauge of wire can not be less than diameter 2mm conventionally.Sunken wire tube is generally longer, also there are several bendings, sometimes because pipe laying construction can make spool generation complications even damaged accidentally, in addition the factor such as the intrinsic toughness of steel wire and corrosion exists, and the steel wire tractive that makes to be reserved in crooked long tube is very heavy, and even tractive is motionless, the rust having is disconnected, block pipeline, pipeline can only be abandoned, and causes the pipe of having buried underground to be abandoned.It two is pre-buried blank pipe methods, and when pipe laying is constructed, direct cloth buries blank pipe, until during break-through cable construction, just for steel wire or other hard tough long lines visit siphunculus road, the then break-through of tractive cable.Obviously, this method of the latter is than the former saving steel, and still, the operation of visiting siphunculus road is but wasted time and energy, and visits passband not high, even no exception for there being the constructor of higher inserting tube and threading experimental technology level.Because, when inserting tube, the resistance that hard tough line moves in constantly mostly being diameter 16mm without the narrow long tube of determining rule bending as house pipe is very big, this resistance mainly comes from this reaction on normal component when the surrender of resistance pipeline of hard tough line, be commonly called as exactly and suppressed or not in pipe, and can visit logical also with the factor analysis such as quality of pipe laying engineering in early stage.Ordinary circumstance is, visits the conventional pipe laying of logical 10 meters of long diameter 16mm, and fast also needed about tens minutes, slow what for to a few hours consuming time, or visits and lead to unsuccessfully.
Stay steel wire method, threading success rate is higher, but waste steel, meanwhile, when pipe laying due to pipe in the existence of steel wire the construction links such as carrying, bend pipe, pipe laying of pipe are required great effort, be also these links increase operation easier simultaneously.After reserved steel wire runs out, substantially go out of use, be unfavorable for stock utilization and environmental protection.Blank pipe method saving steel, but when with inserting tubes such as steel wires, to the level and smooth quality of spool inwall and early stage pipe laying project quality dependence excessively strong, constructor is also had to certain specification requirement, waste time and energy, visit passband not high.The common ground of above two kinds of modes is, all use the long line tractive of the hard toughness such as steel wire cable poling, due to specific operational environment in pipe, make hard tough draught line itself excessive with tube wall frictional force, construction effort, also all also has damage to a certain degree to spool tube wall.
Summary of the invention
The present invention is for solving the current problem that threading exists in stringing; provide a kind of in stringing line sending guide ring and the threading method thereof of threading; the resistance that cable is formed at mouth of pipe inlet wire greatly alleviates; can not only make inlet wire speed greatly accelerate; can also relatively play protective effect to a certain extent to cable epidermis coating, even make must to coordinate the threading construction of carrying out to change into by people's complete independently by two people becomes possibility in the past simultaneously.
The present invention is that the technical scheme that the deficiency that solves the problems of the technologies described above adopts is: the guided rings cap that stringing threading is used, for annular, on the inner peripheral surface of guided rings cap, along even circumferential, be provided with a plurality of draw-in grooves, between two draw-in grooves that face mutually, be provided with buttress platform, buttress platform both sides are provided with the female groove of axle, in draw-in groove, be provided with guide wheel, the wheel shaft of guide wheel is arranged in the female groove of axle that faces mutually two buttress platforms, and the face that rolls of guide wheel protrudes from the end face of guided rings cap.
The face that rolls of guide wheel of the present invention protrudes from the inner circle of guided rings cap.
With guided rings cap, carry out the method for stringing threading,
Step 5, will draw the logical tractive of being fully competent in spool after one end of the secondary lead of threading cable and one end of cable are connected, from the other end of installation pipe, pull secondary lead the end of a thread, until cable in spool completely by break-through, secondary lead and guided rings cap are reclaimed.
Beneficial effect of the present invention is:
1, along with the continuous inlet wire of cable, the truckle of cable and guide ring constantly rubs, and steamboat will ceaselessly rotate with gesture, reduces the friction of cable and installation pipe.
2, the face that rolls of guide wheel protrudes from the end face of guided rings cap; the face that rolls of guide wheel protrudes from the inner circle of guided rings cap; cable is fully preferentially contacted with guide wheel, and do not contact with guide ring cap fixed structure, in order to avoid increase frictional force; when mouth of pipe inlet wire; cable and guide ring are no matter be any angle, and guide ring is all converted into rolling friction mode the friction mode of cable and the mouth of pipe in the past, and frictional resistance is reduced; minimizing cable contacts with stringing pipe, protects cable not to be subject to abrasion simultaneously.
3, this design rolling frictional resistance is minimum, and cable is without artificial line sending, also without when the terminal tractive cable, and the cooperation of request origin or beginning line sending end, this saves manpower work for tractive link realizes mechanization, advantage has been created in automation, raising line sending efficiency.
4, guided rings cap is very small and exquisite, and constructability person carries and uses.Because spool port is together with the common position different on wall of pipe storehouse distribution, where need threading, as long as cap is buckled on the mouth of pipe and can be used.
5, because the anti-degraded resistance of fibers material mass-energy power is strong, and from civil engineering pipe laying to user's threading, fit up the general likely interval time of several years, after this material can guarantee that spool is in being embedded in building structure, many years of the elementary lead-in wire experience that makes to arrange in pipe and corrosion, the phenomenon such as rotten can not occur, this is obviously than staying superior many of steel wire in pipe.Due to from civil engineering pipe laying to wiring interval several years likely, if stay steel wire in pipe, steel wire just gets rusty easily, and can cause it motionless by pull in pipe, and the fracture even having is also blocked pipeline, and pipeline cannot re-use.And if elementary lead riser falls into pipe accidentally, can also tick, easily remedy, the most extreme, even if elementary lead-in wire ruptures completely, also can blow out with blower fan, can also remedy by inserting tube.This break-through rate of just obviously finding out this method is for high, and nothing is left over side effect.
6, the elementary lead-in wire in pipe, conventionally directly do not do the use of tractive cable, but first with this elementary lead-in wire, connect and draw another secondary lead break-through spool, thereby drawing this secondary lead poling only needs elementary lead-in wire line to have less tensile strength.This give user's selection even spool manufacturer selection the very large flexible leeway reducing costs is provided.Compare with reserved steel wire, through initial estimate, this amplitude that reduces material cost can reach more than 97%.The selection of secondary lead, first fully meeting the pull resistance requirement condition of elementary lead-in wire and improving under the condition of self tensile strength as far as possible, select the chemical fibre line of soft smooth, its proportion is much smaller than steel, this is except making it have less static friction and dynamic friction, beyond being more easily pulled by elementary lead-in wire, also make it from can pass through more smoothly pipeline when drag wire cable, just more laborsaving.Thereby, also can draw thus other 2 important conclusions: the one, when the secondary lead tractive cable pipe by this soft smooth, must be less than the friction of using hard tough steel wire tractive to cause pipeline and damage.The 2nd, because elementary lead-in wire is used chemical fibre line, just there is not the corrosion motionless situations such as pipeline of even blocking of tractive that go bad, thereby can further improve break-through rate.So this method just at least makes project quality obtain further raising from reducing pipeline damage and improving two indexs of break-through rate.
7,, because elementary lead-in wire is fibers material, proportion, than little many of steel, does not have the stronger hard toughness of steel wire itself yet, thereby, labour intensity and the difficulty of the operation such as the carrying while not only greatly reducing civil engineering pipe laying and bend pipe, pipe laying.In addition, when break-through cable construction, because this method has been provided with elementary lead-in wire, pipeline has been siphunculus state, ground inserting tube does not just need to waste time and energy, do not have yet blank pipe method when with hard tough long line inserting tube for the so strong dependence of pipe laying process quality in early stage, simultaneously, soft owing to using, light weight and smooth chemical fibre line traction cable, not only make the total frictional resistance of tractive cable than use the larger and quality of hard toughness own also heavier steel wire greatly reduce, and the complications to a certain degree and the breakage that pipeline are occurred when with hard tough line traction cable have stronger adaptability, so operation is not only easily with smooth, also easily accelerate the speed of application of this procedure.
8, from construction cost, fast development due to information technology, family and society are significantly increased for kind and the quantity demand of cable, false in two lines of each need of a three-bed room, should consider not to be straight line wiring, each household need to connect up overall length will be over 100 meters, we need under myriametre wiring simple computation with one hundred houses: according to preliminary understanding, one myriametre 2mm diameter galvanized wire is 4000 yuan of left and right, and a common nylon wire of myriametre diameter 0.2mm or polyester thread are no more than 20 yuan and just can purchase and arrive.Hence one can see that, and the present invention is for extensive construction, and cost advantage is very huge.
9, from environmental protection, the easy oxidation deterioration of steel wire, once oxidation deterioration just becomes waste material, and elementary lead-in wire of the present invention is fibers material, anti-degraded is rotten very competent, all recyclings.From material use efficiency, the present invention just just uses in the link of tractive cable the chemical fibre line that the better cost of tensile strength high-quality is slightly high, and also just as intermediary instrument, uses, can Reusability and preservation, do not affect its other purposes yet.And reserved steel wire method is in the link of tractive cable, each steel wire is passive Cheng Liao intermediary instrument all, and being finished rear preservation is also problem.
10, compare with pre-buried blank pipe method, without personnel's inserting tube of certain experiences technical merit, save time, reduce human cost.Can not make cloth tube failure, not waste Material Cost.

execution mode
As shown in the figure, the guided rings cap that stringing threading is used, for annular, on the inner peripheral surface of guided rings cap 1, along even circumferential, be provided with a plurality of draw-in grooves 2, between two draw-in grooves 2 that face mutually, be provided with buttress platform 3, buttress platform 3 both sides are provided with the female groove 301 of axle, are provided with guide wheel 4 in draw-in groove 2, the wheel shaft of guide wheel 4 is arranged in the female groove 301 of axle that faces mutually two buttress platforms 2, and the face that rolls of guide wheel 4 protrudes from the end face of guided rings cap 1.
The face that rolls of described guide wheel 4 protrudes from the inner circle of guided rings cap 1.
For clarity sake, show guide wheel is cylindricality and the simple case of quantity when less to schematic diagram.In fact, the shape that guide ring inner face surrounds can be also the shape of the close approximation circles such as symmetrical polygon, can be also standard circular.
With guided rings cap, carry out the method for stringing threading:
Step 5, will draw the logical tractive of being fully competent in spool after one end of the secondary lead of threading cable and one end of cable are connected, from the other end of installation pipe, pull secondary lead the end of a thread, until cable in spool completely by break-through, secondary lead and guided rings cap are reclaimed.
The present invention, for shape for hat designs, while wearing cable construction, is burying the fastening of guide ring cap on the installation pipe mouth of pipe, and cable is connected as Fig. 2 with the guide wire of undertaking tractive by guide ring cap center.When tractive cable, in the annulus that guide ring cap is confined to cable be comprised of a plurality of truckles automatically, along with the continuous inlet wire of cable, the truckle of cable and guide ring constantly rubs, and steamboat will ceaselessly rotate with gesture.
By the face that rolls of guide wheel, protruded from the end face of guided rings cap, the face that rolls of guide wheel protrudes from the inner circle of guided rings cap, this is in order to guarantee that cable contacts with the preferential of steamboat fully, and do not contact with guide ring cap fixed structure, in order to avoid increase frictional force, therefore, when mouth of pipe inlet wire, cable and guide ring are no matter be any angle, and guide ring is all converted into rolling friction mode the friction mode of cable and the mouth of pipe in the past, and frictional resistance is greatly reduced.And due in guide ring through being less than caliber, cable is subject to the restriction of guide ring all the time, cable at least cannot contact with tube wall in the certain distance of guide ring, has also just eliminated this part frictional resistance.Compare with the mode that tradition exists without guide ring, the present invention, due to the existence of assembly pulley, has not only alleviated cable running resistance to a certain extent, has also protected to a certain extent cable injury-free.
In addition, the invention enables no matter what angle cable and the mouth of pipe are, it is compensatory that guide ring is all converted into roll mode phenomenons such as cable and the mouth of pipe contacting in the past, friction, extension draw.Because rolling frictional resistance is minimum, cable has prosthetic line sending, and difference is also just little, also, just without when the terminal tractive cable, asks the cooperation of origin or beginning line sending end, and this is for tractive link realizes mechanization, advantage has been created in automation.
The guide ring of shape for hat, very small and exquisite, constructability person carries and uses.Because spool port is together with the common position different on wall of pipe storehouse distribution, where need threading, as long as cap is buckled on the mouth of pipe.
The method is that the method for leading is drawn in a kind of circulation, and it comprises and elementary lead-in wire is set and circulation strengthens lead-in wire and three operation links of tractive cable siphunculus.Elementary lead-in wire link is set and refers to before installation pipe is buried underground, in spool, penetrate in advance the rotten soft chemical fibre line of a kind of difficult degraded that has preliminary tensile strength, two rear line heads are fixed at the two ends of pipe respectively reserve enough redundancies in pipe after.Circulation strengthens lead-in wire link and refers to, until during break-through cable construction, first by elementary lead-in wire connect and draw logical another tensile strength higher and can be competent at the chemical fibre line that pulls completely as secondary lead in pipe by elementary lead-in wire.The operation that this circulation strengthens lead-in wire can optionally be carried out several, and the tensile strength that makes to stay the lead-in wire in pipe successively increases.Tractive cable siphunculus link refers to by being strengthened to last secondary lead and connects cable to be worn its break-through spool of tractive.
Elementary lead-in wire generally should be stopped redundancy in pipe depending on concrete condition, reserving sufficient redundancy is not mainly to be pulled off in order to guarantee that elementary lead-in wire is done when bend pipe operates when pipe laying is constructed, and usually can stay 20% left and right.The setting of two stomidiums is convenient in order to illustrate fixing elementary lead-in wire, certainly also other fixed forms.The elementary lead-in wire of pipe connects and operated before pipe laying, is very easy to, for example, during manual operation, can first accomplish fluently stomidium, then on the end of a thread, fastens suitable weight, puts into pipe, and pipe is tilted to rock, and weight drives elementary lead-in wire break-through pipe.The setting of elementary lead-in wire should also be noted that 2 points: one will prevent that elementary lead riser from getting loose voluntarily, slips in pipe, and two will note when pipe need to continue, and in the lump elementary lead-in wire is connected, and then just can imbed in building structure.
Selection about the tensile strength of elementary lead-in wire, can find out from the foregoing, as long as the tensile strength of elementary lead-in wire can be greater than self and secondary lead maximum resistance when current in pipeline, circulation strengthens the possibility that just has realization, yet, spool length is different in size, to be embedded in building structure be also that different, spool tube wall has or not burr while manufacturing, and these are all difficult to assurance.By complicated calculating, obtain least limit, practical significance is also little, reason is, circulation strengthens take sacrifices continuous cycling as cost, and fibers material is as very cheap in nylon, terylene etc. at present, and it is meticulous that elementary lead-in wire is selected, not only sacrifice skill in man-hour, safety reliability is also inadequate, once fracture can make trouble on the contrary.With the limited experiment of inventor, for 15 meters of long tubes, the maximum resistance being run into by elementary lead-in wire tractive 2mm nylon wire process generally can not surpass 0.5kg, but, in order to have higher safe and reliable redundancy and ease-to-operate, think that elementary lead-in wire should reserve 2 times of redundancies and reach 1.5kg above for well.Use the common nylon wire of diameter 0.2-0.5mm both economical and more safe and reliable, in this scope, the data of finding according to preliminary understanding, domestic common nylon tensile strength is distributed in 1.8kg-9kg, the 3-20kg that can distribute that quality is better, more than the 0.2mm nylon tension of better quality even can reach 13kg.The selection of elementary lead-in wire generally can make once to strengthen to go between to operate and just can be able to the most of cable of tractive for best, has special circumstances, secondary enhancing, otherwise the loss of the efficient aspect of meeting or safety reliability aspect.
In the practice of construction of wiring, how wiring personnel often generally do not know to imbed in advance the nylon quality of the elementary lead-in wire in pipe and tensile strength numerical value thereof early stage, because the difference in quality of chemical fibre line is very large, the 0.2mm diameter nylon line of take is example, its intensity has product from 1.8kg-13kg, before being used, must test by elementary lead-in wire, can not singlely according to wire diameter, determine pulling force, so, the first step, first to first cut off the lead-in wire the end of a thread on port of Sunken wire tube, to cut one section of elementary lead-in wire, the method that general available hand examination is drawn is tested its about intensity, if the elementary lead quality that early stage, construction arranged is better, resistance to tension is strong, and tube side is short, treat that threading cable is again the flexible cord easily drawing, also direct tractive, this should be the zero a kind of special case strengthening described in this method.If be not sure, just must select secondary lead, to carry out enhancement operation.Selecting the principle of secondary lead is that the pull resistance that first must meet elementary lead-in wire requires under prerequisite, selects tensile strength to compare the smooth nylon wire material in line surface that numerical value is large as far as possible with wire diameter as far as possible.Due to secondary lead be as instrument at Reusability, therefore, should take quality as first, minimum so that its wire diameter and weight are dropped to, this can not only lower elementary lead-in wire traction load, also alleviates from self resistance when drag wire cable simultaneously.
For general house threading, selecting chemical fibre line more than tension 50kg is generally enough as ultimate lead-in wire, because when tractive cable, the fail safe of excessive pulling force cable does not allow yet.When tractive family expenses cable, general sensation, when being greater than 5kg, will be noted and careful and slow-down, think various way protection cables.No matter be to strengthen lead-in wire or tractive cable, origin or beginning all will have people to assist line sending, prevents that nose end from drawing lead-in wire or cable extension, causes new tractive resistance or damage cable.
Strengthen in addition operation and be not that to increase wire diameter be object, but take, the tensile strength of the lead-in wire in reinforced pipe is object, in particular cases, if run into the extremely weak situation of elementary lead-in wire, we also can select a kind of than the thinner lighter but higher secondary lead of intensity of elementary lead-in wire.See embodiment 1.
Because the resistance in operation has the many factors that cannot hold in advance, again connect line in addition and bother very much, so, every operation one step all will leave sufficient assurance and redundancy, with safe and reliable, do not break as primarily considering, in order to avoid give rise to trouble, lose more than gain on the contrary.But in any case, if in the operating process of certain step, just find that prime lead-in wire has the situation can't bear the heavy load to occur, at this moment also need not be difficult, as long as oppositely draw and pull out front from the spool other end, allow problem come back to step state, then rearrange circulation enhanced scheme and reach a solution of a problem surely with regard to one.In addition, for professional threading constructor, repeatedly the operation of circulation enhancing lead-in wire should be by take-up instrument or machines such as wheel discs, to accelerate speed of application.
Example 1 cloth line object is the common Sunken wire tube of 10 meters of long diameter 16mm in house, and the elementary lead-in wire in pipe is that the thin nylon wire of diameter 0.18mm or polyester thread are hard to tell, and through its tension of test discovery, approximately only has 1.0kg upper and lower, prepares to wear soft telephone wire.Suggestion: can be first with the thin nylon wire of high-quality more than the tensile strength 3kg of 0.13mm diameter as secondary lead, and use guide ring cap to guide at the inlet wire mouth of pipe, after perforation, draw again the logical above nylon wire of 2mm diameter and just can try to have led telephone wire.
Example 2 cloth line objects are the common Sunken wire tubes of 5 meters of long diameter 16mm in house, and in pipe, elementary lead-in wire is diameter 0.5mm nylon wire, through test, find that its tension is greater than 6kg, and waiting to wear is soft telephone wire.Suggestion: can directly draw telephone wire and try on, if feel that situation is abnormal midway, can, from oppositely again telephone wire being pulled out, make problem get back to previous step state again.Then, middle enhancing once goes between intensity after the above nylon wire of 2mm diameter, then tries on.
Example 3 cloth line objects are the common Sunken wire tubes of 5 meters of long diameter 16mm in house, and in pipe, elementary lead-in wire is diameter 0.5mm nylon wire, through test, find that its tension is greater than 6kg, and waiting to wear is 8 core broadband 10/100M netting twine or closed-circuit television lines.Suggestion: can be first with nylon wire more than tensile strength 70kg more than 6mm diameter as secondary lead, and use guide ring cap to guide at the inlet wire mouth of pipe, tractive netting twine or tv line again after perforation, these two kinds of cables are all harder, also need to have people's special on-line pipe other end in pipe, to coordinate the rhythm line sending of pulling strings with strength, can not depend merely on hard draw, otherwise can damage cable, can also on cable surface, smear a little lubricant if desired temporarily.
