Description

Buried type garbage compression device lifting balance system
Technical field
The present invention relates to a kind of buried refuse compaction equipment, be exactly specifically that a kind of buried type garbage compression device can make to be arranged on the lifting balance system that equipment surrounding synchronizes in order to four oil cylinders supporting the lifting of whole equipment steadily to lift by a hydraulic control center.
Background technology
At present in the field of garbage disposal of China, buried type garbage compressor is with its disguise processing rubbish and efficientibility, and has been commercially available extensive utilization and universal. And whole equipment body must be risen to more than ground level when many situations such as rubbish entrucking, maintenance by this buried process equipment, to facilitate other to operate. And take plunger cylinder is separately mounted to equipment surrounding, but there is problem in order to the method for lifting equipment main body: four cylinders lifting speed differ Complete Synchronization etc. surely.
Summary of the invention
In order to solve Problems existing in the four cylinder Lifting Technique that buried type garbage compressor is taked, it is proposed to buried type garbage compression device lifting balance system, perfect four cylinder synchronous liftings of refuse compaction equipment.
The technical solution used in the present invention is: a kind of buried type garbage compression device lifting balance system, including fuel tank and more than two hydraulic jacks, it is characterized in that: described fuel tank connects more than one vane pump through oil absorption filter, more than one vane pump connects electro-hydraulic reversing valve through more than one check valve respectively, electro-hydraulic reversing valve connects the hydraulic motor of more than two through branching block, every hydraulic motor all connects hydraulic jack through hydraulic control one-way valve, hydraulic control one-way valve overflow connects electro-hydraulic reversing valve, electro-hydraulic reversing valve overflow backflow connects fuel tank, the main shaft of every hydraulic motor is all socketed with gear, it is engaged with idler gear between above-mentioned two gears, hydraulic motor is connected to draining fuel tank.
Further, described hydraulic control one-way valve is connected to draining fuel tank.
Further, it is connected with Pressure gauge and electromagnetic relief valve in turn between connecting line and the fuel tank between vane pump and check valve.
Further, the main shaft of described vane pump connects motor through shaft coupling.
The motor controlling hydraulic jack, to reach two with the technology of upper cylinder synchronous lifting, is together in series by the hydraulic motor controlling hydraulic jack respectively by connecting by engaged gears. When wherein certain oil cylinder meets rotation oil mass, owing to the gear with other hydraulic motors is engaged through idler gear, can't rotate but automatic draining, rotate a circle when two oil cylinders are satisfied by rotating oil mass Shi Caihui collective, equivalent hydraulic oil is separately input to elevating ram, thus forming the effect of multi-cylinder synchronous. What this wherein involved hydraulic motor adopted is radial plunger piston motor, adopts engaged gears to connect between any two, finally adopts one group of engaged gears to connect hydraulic motor two groups engaged again, thus forming collective's series connection of many hydraulic motors.
Adopt above technical characteristic, the invention has the beneficial effects as follows: connect oil circuit by changing, series connection controls the hydraulic motor of more than two elevating rams, reach the effect that multiple elevating ram synchronizes, improve the noise that trash compactor causes because multiple elevating rams are uneven in lifting process and exceed standard, lift the problems such as unstable.Perfect original multi-cylinder Lifting Technique, compared with the original hoistable platform adopted, structure is simpler, and performance is more stable.

Fig. 2 is hydraulic motor bindiny mechanism of the present invention schematic diagram.
In figure: hydraulic jack 1, hydraulic control one-way valve 2, hydraulic motor 3, electro-hydraulic reversing valve 4, Pressure gauge 5, electromagnetic relief valve 6, motor 7, vane pump 8, shaft coupling 9, oil absorption filter 10, check valve 11, branching block 12, draining fuel tank 13, fuel tank 14, gear 15, idler gear 16.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1, shown in 2, a kind of buried type garbage compression device lifting balance system includes: hydraulic jack 1, hydraulic control one-way valve 2, hydraulic motor 3, electro-hydraulic reversing valve 4, Pressure gauge 5, electromagnetic relief valve 6, motor 7, vane pump 8, shaft coupling 9, oil absorption filter 10, check valve 11, branching block 12, draining fuel tank 13, fuel tank 14, gear 15, idler gear 16.
As shown in Figure 1: one end of oil absorption filter 10 is connected fuel tank 14, the other end connects vane pump 8, motor 7 is connected on vane pump 8 by shaft coupling 9, vane pump 8 is connected with check valve 11, the while of in the middle of the oil circuit that vane pump 8 and check valve 11 are connected, electromagnetic relief valve 6 in parallel and Pressure gauge 5 are used for the oil pressure monitoring in oil circuit, the other end of check valve 11 accesses electro-hydraulic reversing valve 4, branching block 12 is out accessed afterwards from electro-hydraulic reversing valve 4, the oil-in of four hydraulic motors 3 out it is respectively connected to afterwards from branching block 12, the oil-out of four hydraulic motors 3 is connected in the oil-in of four hydraulic control one-way valves 2 respectively, the oil-out of four hydraulic control one-way valves 2 is connected to four on the hydraulic jack 1 that lifts, the drain tap of four hydraulic control one-way valves is connected in series to draining fuel tank 13, the oil return opening of four hydraulic control one-way valves 2 is connected in series to electro-hydraulic reversing valve formation oil return circuit and is ultimately connected to fuel tank 14. the drain tap of four hydraulic motors is also together in series and is connected to draining fuel tank 13, four hydraulic motors 3 one group between two, the main shaft of two hydraulic motors is corresponding socket one gear 14 coaxially, and another two hydraulic motor main shafts of group are coaxially corresponding is socketed another gear, engages through idler gear 15 between two gears.
When motor 7 starts, vane pump 8(duplex pump is driven by shaft coupling 9) rotate, hydraulic oil in fuel tank enters in check valve 11 through oil absorption filter 10 through vane pump, oil pressure can be monitored and regulate by Pressure gauge at this moment in parallel with check valve and electromagnetic relief valve, hydraulic oil out enters electro-hydraulic reversing valve afterwards and out enters branching block afterwards from check valve, hydraulic motor is respectively enterd after shunting, if after at this moment certain hydraulic motor reaches rotation oil mass, owing to passing through gear 15 with other three hydraulic motors, idler gear 16 is connected together, can't rotary work, but automatically draining is to draining fuel tank, only after four hydraulic motors entirely reach rotation oil mass, Cai Hui collective rotates a circle, the hydraulic oil of equivalent is sent in hydraulic control one-way valve 2, worked by hydraulic control one-way valve 2 again and the hydraulic oil of equivalent is input in four lifting hydraulic jacks, hydraulic jack is promoted to carry out lifting action, oil mass owing to inputting four hydraulic jacks is equal, so the lifting action of four hydraulic jacks is Complete Synchronization. if desired hydraulic jack is in certain specified point stopping action, as long as closing electro-hydraulic reversing valve 4 after arriving specified point.After the action of a series of needs completes, oil cylinder can oil return under the Gravitative Loads of trash compactor itself, oil return exits into solenoid directional control valve 4 through hydraulic control one-way valve 2, from solenoid directional control valve 4 out after oil return enter directly into fuel tank.
