Description

Amphibious moving concrete mixing station

The utility model belongs to the technical field of big capacity concrete (abbreviation of t ó ng cement concrete) mixing plant in the engineering machinery.

Big capacity concrete mixing station is the necessaries of modern large-scale construction project.Usually divide two kinds of the formula that fixes and reassembling types.Because of very inconvenience of fixed installation removal, so reassembling type is comparatively popular.China's import the reassembling type product of a collection of West Germany Si Tante, Liebherr, love Bhujerba company, also there is imitation on ground such as Xuzhou, Shaoguan, some new varieties are located to have developed in succession in Jinan, Zhengzhou, Xi'an etc., and the conventional small mixing plant of Shanghai, Jiangyin, Fuxin is also peddled sound and happened frequently.But no matter be homemade, import, still to copy abroad, volume is all too huge, and mobility is relatively poor.Indivedual kind mobility are stronger, but capacity is less, and designed productive capacity is usually at 25m ³About/h.Every single machine yield is at 40-60m ³The volume of/h is all huge, and majority has tall and big sandstone material barricade, not only purchases and the mounting cost costliness, must spend about one month could Installation and Debugging ready.Even,, must not spend ten days first quarter moons owing to will play concrete basis and several big assembly unit debugging with the storing bucket type of barricade yet.This for often will the section of turning over, the highway and the bridge construction of resettlement be very unfavorable.For example our unit is once in Nanjing---and buying two designed productive capacities in the construction of Hefei highway is 60m ³The Bhujerba concrete mixing station is liked by the West Germany of/h, installs and spends for two wheat harvesting period times, and installation fee is used up more than 20 ten thousand yuan.Along with the extension on road surface, the haul distance of concrete surpasses ten kilometers, 30 kilometers farthest, so want very much with wherein one move 15 kilometers places to, but remove and can't implement because of tangible difficulty, have no alternative but the road surface of distant place is subcontracted to others.Although mixing plant itself is advanced in performance,, profit has on hand been run off because of the mobility difference is difficult to give full play to.Want today to come, if adopt the identical the utility model of production capacity, on-the-spot removal of home only needs time half a day, and installation fee only needs thousands of units, comes into operation just can debug to finish, and just can go out the output value same day.

At present, along with the fast development of communication, as looking like to emerge rapidly in large numbersBamboo shoots after a spring rain, builds everywhere large bridge.One of key equipment of construction---concrete mixing station waterborne but is difficult to seek, and has become road blocking tiger.Foreign ship of import with this equipment, must take ten million yuan, cannot afford, usefulness again, everybody have to bring up to ship or buoyancy tank with various simple and crude mixers, with manually or the semi-mechanization material loading, the gesture that " plodding away at a big job bit by bit " quite arranged, production efficiency is low, and hundreds of side's concrete under water often wants the open clouds until dawn, even several could the cast round the clock finishes.The mode of production of this backwardness is extremely incompatible with the development situation of advancing by leaps and bounds and pressing duration.Have no alternative but, indivedual units load onto buoyancy tank with the land with mixing plant firmly by force, although be the less 25m of capacity ³/ h level, it is too tall and big but to have seemed, unbearably clumsy.See more the aborative masterpiece of unit in charge of construction, understood their an urgent demand, firm I design amphibious, the capacity large volume is little, can fold a kind of new departure of whole moving defeated Fast Installation.So, the bulkiness of conventional mixing plant is cut down 2/3rds, adopt the height simplification of original design implementation structure and the optimization of system, guarantee that combination property does not only reduce, reverse side is more superior, especially is fit to the two-shipper parallel connection and is contained on buoyancy tank or the ship, makes the main frame of concrete mixing station waterborne.

Chapter 1---" concrete batch plant " describes pandemic various type in detail to " the external concreting machinery " of comrade's Gong Tieping compiling, and existing full text duplicates as annex for examination.Wherein mention some and the utility model approaching type on discrete function, for example Japanese ball friend mobile mixing station, similar aspect mobile in integral body, the machine inner structure is completely different, and is 25m ³/ h level.And for example Bhujerba EMM type mixing plant is liked by West Germany, and its mixer that climbs is similar with the utility model on function, but the structure of mixer and parts all have than big-difference and improvement.Picture 1-45,1-46 demonstrate the huge volume of EMM, tall and big barricade, separate type several big, also have the scale hooper of a special use, and the certain altitude that climbs is tumbled reinforced to the mixer that climbs.And the utility model has combined scale hooper, the bucket that climbs, stirring bucket three together, has had the difference of matter than " melting three is two " of EMM.The complete machine one integrated mass, the superelevation super wide part is folding, has demonstrated combination property of the present utility model and has had superiority.The ecp automatic gauge conveying pot that shows unique characteristics has changed conventional water pump, and---time relay, water pump---water meter, water pump---structure of too busy to get away electric water pump such as measuring tank need only be blown into one gas, just can finish whole procedure.

The purpose of this utility model is to release a kind of production capacity and mixing quality and catches up with West Germany's famous brand machine, can be folded into container size, whole shipment, Fast Installation, can go into operation the same day, simple for structure, cheap, long-lived, amphibious, maneuverability, adaptability are extremely strong, the world-class concrete mixing station that can play obvious facilitation to the construction of motherland, be enough to upgrade.

The purpose of this utility model is achieved in that at upper rack the base plate and the frame in sandstone storehouse are welded into one, and side plate and median septum then connect with loose-leaf and base plate, thereby one-tenth capable of being combined storehouse, also can or tile by the loose-leaf suspension.The cylinder operated sandstone door of sandstone material process in the storehouse directly slide goes in the mixing drum to accumulate weighing.Material in cement bin and the handstone storehouse enters scale hooper by conveying worm, opens sluice gate by electromagnet then, and also mixing drum is gone in slide under the effect of hopper wall vibrator.Water and additive flow into the automatic gauge conveying pot from cabinet separately, when electromagnetic gas valve moved, water and additive sprayed in the mixing drum automatically by sebific duct under the compressed air effect.Having only an opening on the mixing drum, is charging aperture, discharging opening or inspection socket when also being upset.In the tube shaft is arranged, be welded with supporting leg and auxiliary blade on the axle, leg ends is welded with arc shaped blade, studs with abrasion-proof backing block on blade and the inwall.The end plate of tube is equipped with bearing, reducing motor seat, reducing motor outward.Bearing, sprocket wheel, change gear are equipped with in the outer end of shaft.Reducing motor is by chain, the rotation of chain wheel drive shaft, and six kinds of materials of process metering are finished under the promotion of stirring vane and mixed and stirred in the mixing drum.These inside and outside parts of mixing drum have been formed the tilt bed list horizontal axis two-region convection current forced stirrer that climbs jointly, and it is supported on the guide rail hypomere of a part that becomes the sandstone burden balance.The batcher of sandstone burden balance is fixed on the water tank, and mechanical display devices and electronic sensor are housed in the batcher, to guarantee the conversion of mechanical weighing and projection electronic weighing two states.The stage casing of guide rail is welded on the frame, and the epimere of guide rail and stage casing link with rotating shaft and latch, and is suspended on the sandstone storehouse by steel wire rope and tightening bolt.Traction reducing motor, capstan winch, steel wire rope that band brake is equipped with on the top of guide rail epimere draw mixer with this and move up and down.Mixer climbs while stirring, and is raised to certain altitude, promptly enters turning device, comes an end towards the sky, and charging aperture becomes discharging opening, and the concrete that stirs draws off under deadweight and stirring vane effect.The control room is contained in frame front, is threaded to the frame side by latch and guide during work.Circuit, gas circuit, water route are installed in factory, are debugged, and come whenever moving all will dismantle unlike other mixing plant, thereby save many Installation and Debugging times.When the sandstone storehouse disassembles, the control room is threaded to the frame front end, when the guide rail epimere spins down, the appearance and size and the weight that are in the complete machine of folded state all are similar to container, can whole load and transport, and is quick for installation, need not beat the concrete pedestal, need only folded part is launched, a pad is firm, and connection power supply, water source can come into operation.40-60m ³The production capacity of/h, metering method, whipped form are all loved Bhujerba EMC60 machine not second to West Germany, thereby the purpose of this utility model is enough to realize.

Owing to adopt such scheme, the vacancy of the concrete mixing station waterborne of China's urgent need is filled up, can make the speed of application of broad waters and strait Bridge accelerate several times.Also be applicable to viaduct building site narrow in overpass and the big city, be installed in below the bridge belly that big mixing plant can't come back maneuverability, or be dragged on the beam face that big mixing plant can't go at all and carry out operation.Even in the middle of crowded machinery group gap, the Tall Building Foundation construction site of enclosure wall the inside, also very easily find a fritter to be fit to its place to stay, come the reduction of erection time significantly with the mixing speed and the outstanding quality that are exceedingly fast.Because it is convenient to resettlement than big mixing plant, the highway of the most suitable often section of turning over uses.For overcoming the little facility operation of the craft that dominates in the present concrete pavement construction, realize that large-scale concrete spreads out the machine of catching and constructs, will play conclusive supporting and facilitation.Thereby economic benefit and social benefit that the enforcement of this utility model brings all will be huge.

Has only an opening 51 on the mixing drum 56 of the tilt bed list horizontal axis two-region convection current forced stirrer 36 that climbs that slides up and down along guide rail 2,32,34.Stirring is taken out and is welded with supporting leg 54 and auxiliary blade 55 on 59, the end of supporting leg is welded with arc shaped blade 52, stud with abrasion-proof backing block 53 on blade and the inwall, in the bearing block 50 outside the end plate bearing 60 is housed, big change gear 49 is housed on the bearing 60 at shaft 59 two ends, on the bearings at both ends 63 of little axle 62 little change gear 64 is housed, high-power reducing motor 66 is housed on the motor seat board 61, by minor sprocket 65, chain 57 drives hinge wheels 58 shaft 59 of tending to act.This structure is fit to heavy-load start and climbs.After mixer 36 climbed guide rail epimere 2, little change gear 64 enters rose as high as the banks 6, and when being against the corner of intersecting with upright groove 4,49 of big change gears up turn over along cambered way 9, then mixer 36 the individual end towards the sky.Climb and still continuing, big change gear 49 is being drawn close to the top of guide rail epimere 2, and little change gear 64 rises along upright groove 4 again, until routing up upright groove 4.When mixer 36 glided, little change gear 64 was got back to upright groove 4 again, treated that big change gear by behind the cambered way 9, enters and rises as high as the banks 6, continued to glide.

Ecp automatic gauge conveying pot (29) is adopted in the metering of water and additive.The below of jar 74 is welded with water inlet pipe 88, and there is the check valve 87 around axle 86 rotations the inside.The central authorities of jar 74 are inserted with the water spray steel pipe 73 of band scale, lean on threaded circle 84 and hollow cap 83 to compress sealing ring 85 and come sealed tube wall.Water spray steel pipe 73 tops are clamped by lifting folder 70, and the other end of lifting folder 70 has lifting screw 68, lifting handle 69, rotary sleeve 71 and dog screw 72.Termination sebific duct 67 on the steel pipe 73, next door have the air inlet pipe 82 of logical gas storage box 81.The air blast that can discern to come from electromagnetic gas valve 80 directions is arranged on the top of gas storage box 81 and be isolated or the device that communicates with atmosphere with decision, form by silk braid 75, hollow blind nut 77, sealing gasket 76, spike valve 78 and sealing ring 79 from weak air-flow and automatic open close that jar 74 directions are come.The operation principle of this device is: water tank 38, additive cabinet 27 are than the position height of conveying pot 29.Water or additive are pushed check valve 87 open along water inlet pipe 88 under the head pressure effect, enter jar 74 to being full of and entering sebific duct 67 and air inlet pipe 82 on a small quantity, reach till the pressure balance, and check valve 87 is closed under the deadweight effect.When signal is sent in control room 24, during the of short duration unlatching of electromagnetic gas valve 80, one powerful air-flow is blown into gas storage box 81 and air inlet pipe 82 at once.The air-flow that this strand pressure is very high expands rapidly, and water in the jar 74 or additive are extruded from water spray steel pipe 73, sprays in the mixing drum 56 along water spray sebific duct 31.The very fast declines of liquid level in the jar 74, when reducing to the end opening that exposes the steel pipe 73 of spraying water, in the compressed air drill inlet, along rushing down outside the water spray sebific duct 31, jar internal gas pressure recovers normal pressure, and the liquid that is lower than water spray steel pipe 73 end openings can't spray.Thereby the insertion depth of change water spray steel pipe 73 end openings just can be adjusted injection flow rate.The lifting screw 68 at jar 74 tops, lifting folder 70, lifting handle 69 etc. are exactly the device that is used for adjusting, and the scale on the water spray steel pipe 73 can accurately be indicated injection flow rate.After once water spray finished, under the hydraulic pressure effect, the check valve 87 into water that is open again entered next circulation.A thorny key issue is arranged here, determining the success or failure of complete unit.When liquid level in the jar 74 rises, buried the end opening of water spray steel pipe 73, and the air of system's inner sealing is with the dwindling and be compressed of space, liquid level just can not go back up to due height.Allow liquid level continue to go up, just intrasystem compressed air must be bled off.In other words, must a kind of device of design, the identification air-flow come to, when the air blast of electromagnetic gas valve 80 directions comes then, device is closed automatically.And when finishing water spray, after air blast overflowed, device was opened, and in the overall process of rising of groundwater level, all was in opening, so that the weak air-flow that jar 74 directions are come overflows thus.Whether reliably this device is determining the degree of accuracy of metering, be system's key point.If will do a kind of electric control gear and finish this mission, that will be parts too fat to move mechanisms numerous and diverse, that be not complementary with jars 74 automatic circulation.Through the contrast of plurality of proposals, the spike valve 78 schemes finger tip size, very simple and reliable have finally been selected to have only.Its operation principle is as follows: at ordinary times, spike valve 78 is parked in therapeutic method to keep the adverse qi flowing downward hole site because of deadweight, and nail covers the such sulculus of wood snail wire cover one, is convenient to breathe freely.When air blast arrived, air-flow was gone out from aperture, and flow velocity is very high, produced a negative pressure, and spike valve 78 is picked up by air-flow under action of pressure, flings pore.Sealing ring 79 last air-vent cap tight.Air blast is given the deadweight of the pressure of shape valve 78 greater than valve, thereby it not only can fall, and presses enough tightly.By the time water spray finishes, and when recovering normal pressure in the system, spike valve 78 falls down under the deadweight effect, gets back to down the position of pore again.Beginning this moments jars 74 adds water automatically, and the compressed air oncoming force is so not fierce, though also producing pressure differential by spilehole when excessive, also be not enough to offset the deadweight of spike valve 78, fills it up with until water, is in opening always.Certainly, the size of spike valve 78 and weight are very crucial.

Realize that the utility model should have the ability of manufacturing heavy construction machinery and the large and medium-sized enterprise of experience to practice midwifery by technical force and solid financial strength.In finishing art work sheet design, parts mix selection and processing and manufacturing, should follow following requirement:

1, high level: host capacity, production capacity, technical level, computer system are all with world's famous brand---West Germany's love Bhujerba machine is dressed;

2, aspect dual fail-safe: at key position---the Weighting and Controlling, adopt mechanical type and electronic type two to overlap independently system, so that convenient conversion when being out of order, being unlikely influences construction operation;

3, supporting ingeniously: as to abandon heavy vertical cement jar, select the bulk cement container for use.This bulk cement container uses in the Three Gorges Projects, and domestic existing manufacturer production is handy flexibly, is developing direction.This machine is supporting with the sandstone feed bin that is contained on buoyancy tank or the ferryboat, forms concrete mixing station waterborne, will take the course of its own;

4, performance is complete: be suitable for various abominable construction occasions, and quick, convenient, mobility is extremely strong, surpasses various large-scale concrete mixing stations with landslide;

5, the shelves that fan the air: big capacity concrete mixing station waterborne is a vacancy, is sought after, and this prow is exhibited one's skill to the full earlier on the water, positive so-called " beating all over three rivers unopposed ", and transition is landwards then ranked among the land of numerous clumsinesses and is used among the mixing plant, progressively replaces;

6, valency is cheap: because simple for structure, thereby cost and price are cheap.

Follow mentioned above principle, just had and realized best way of the present utility model.
