Description

Amphibious moving concrete mixing station

The invention 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 heavy construction.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 ³/ h is above, and volume 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 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 once to buy two designed productive capacities in Nanjing-Hefei highway construction be 60m for our unit ³The Bhujerba concrete mixing station is liked by the West Germany of/h, installs and spends two a plurality of months, 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 present invention 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.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 at present.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 Transporting 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, superior all the better, especially be fit to the two-shipper parallel connection and be contained on buoyancy tank or the ship, make the main frame of concrete mixing station waterborne.

" external concreting machinery " chapter 1-" concrete batch plant " of comrade's Gong Tieping compiling describes pandemic various type in detail, and existing duplicating in full is as annex, for examination.Wherein mention some and the present invention 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 present invention 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 present invention 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 invention and has had superiority.The ecp automatic gauge conveying pot that shows unique characteristics has changed the structure of too busy to get away electric water pumps such as conventional water pump-time relay, water pump-water meter, water pump-measuring tank, need only be blown into one gas, just can finish whole procedure.

There is additive cabinet 27 front portion of frame 33, air compressor 28, water spray sebific duct 31, electromagnetic gas valve case 30.There are cement and handstone storehouse 23 in the rear portion.Conveying worm 39 adopts and can open the open architecture of being convenient to get rid of plugging fault by overall length, and reducing motor 40 is housed on the seat board of lower end, drives spiral work by chain and sprocket wheel 41.Also have cement and handstone scale hooper 18, open the electromagnet 20 of sluice gate 22, hopper wall vibrator 19, cement and handstone scale 21, water tank 38.Sandstone burden balance 35 are arranged at the bottom of frame 33, and guide rail hypomere 34 is supported on the sandstone burden balance 35, and the burden balance case 37 that mechanical display devices and electronic sensor are housed is fixed on the water tank 38.Similar device is also arranged, to realize mechanical scale and electronic scale dual fail-safe on the cement weigher 21.It is packed that cement adopts, also can with the combined use of horizontal or vertical bulk cement storage tank.

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.Be welded with supporting leg 54 and auxiliary blade 55 on the shaft 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, drive hinge wheels 58 shaft 59 of tending to act by minor sprocket 65, chain 57.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, so 36 ends of mixer are 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, 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 room 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 covering 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.This strand pressure is rapid swollen the rising of high gas flow very, and water in the jar 74 or additives are extruded from water spray steel pipe 73, and sebific duct 31 sprays in the mixing drum 56 along spraying water.。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.It is exactly the device that is used for adjusting that 70 lifting handles, 69 grades are pressed from both sides in lifting screw 68 liftings at jar 74 tops, 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 and opens the dress attitude, 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 spike 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.Spike valve 78 is unremarkable after doing successfully, even is ridiculed by people.Yet friends' examination paper slight in this road have been handed over clumsy and numerous and diverse in front invariably even have not been had the test paper of separating.
