Description

Ground pit type compression garbage station casing synchronous lifting device
Technical field
The utility model relates to a kind of compression garbage station, particularly a kind of ground pit type compression garbage station casing synchronous lifting device.
Background technology
The compression garbage station of existing market, lifting mostly is pressure head hoisting type, mode such as scissors fork lifting mechanism, four post lifting mechanisms (oil cylinder is fixed on ground) etc., therefore whole garbage apparatus height is high, ground gives and buries complexity, in required house, outage degree is also high, difficulty is installed simultaneously, equipment cost and operating cost high.
Utility model content
The purpose of this utility model is the deficiency existed for above-mentioned prior art, provides a kind of ground pit type compression garbage station casing synchronous lifting device.This its lifting framework of ground pit type compression garbage station casing synchronous lifting device is not by load effect, and synchronous lifting precision is higher, and melt pit is built more simple, need not pre-buried oil cylinder mounting foundation, requires lower, simple installation, reduction device fabrication cost to height of house.
The technical scheme of the utility model ground pit type compression garbage station casing synchronous lifting device comprises Hydraulic Pump, high-pressure overflow valve, low pressure relief valve, change-over valve and some single-acting elevating rams, the described single-acting elevating ram of described rubbish container its many is provided with a sync control device, described sync control device comprises a synchronous motor, one hydraulic fluid port of this synchronous motor is connected with a hydraulic fluid port of described change-over valve, and another hydraulic fluid port of synchronous motor is connected with single-acting elevating ram.
Also comprise a high/low pressure cut-over valve be connected with described low pressure relief valve.
Described low pressure relief valve is connected between corresponding two hydraulic fluid ports of change-over valve after being mutually connected in series with corresponding high/low pressure cut-over valve, described high-pressure overflow valve is connected to corresponding two hydraulic fluid ports of change-over valve.
Not only structure is simple, practical for the utility model ground pit type compression garbage station casing synchronous lifting device, employing synchronous motor controls, and can improve the synchronization accuracy of four oil cylinders, and can greatly reduce device height and house, Refuse bin is high, and the complexity of melt pit design, manufacturing cost is lower.
Accompanying drawing explanation
Fig. 1 is the hydraulic control system connection structure schematic diagram of the utility model one embodiment elevating ram.
Detailed description of the invention
In order to understand the technical solution of the utility model further, by following examples, the utility model is described in further detail by reference to the accompanying drawings.
As shown in Figure 1, this ground pit type compression garbage station casing synchronous lifting device comprises Hydraulic Pump 1, high-pressure overflow valve 2, low pressure relief valve 4, high/low pressure cut-over valve 3, change-over valve 5, synchronous motor 6, single-acting elevating ram 7 etc.
The cylinder barrel of four single-acting elevating rams 7 is separately fixed on rubbish container (casing), and the plunger end of four single-acting elevating rams 7 adopts ball pivot flange free end bearing to be connected at the bottom of the hole of melt pit respectively.Namely single-acting elevating ram 7 is that its cylinder barrel and rubbish container (casing) rigidly fix, and the plunger end of single-acting elevating ram 7 is connected by ball pivot flange to be in suspended state.
The output oil port of Hydraulic Pump 1 is connected to the corresponding hydraulic fluid port of high-pressure overflow valve 2, high/low pressure cut-over valve 3 and change-over valve 5, high/low pressure cut-over valve 2 is connected to a corresponding hydraulic fluid port of low pressure relief valve 4, high/low pressure cut-over valve 2 is connected to corresponding two hydraulic fluid ports of change-over valve respectively with another hydraulic fluid port of low pressure relief valve 4, high-pressure overflow valve 2 is connected to corresponding two hydraulic fluid ports of change-over valve 5, another hydraulic fluid port of change-over valve 5 is connected with a hydraulic fluid port of synchronous motor 6, and another hydraulic fluid port of synchronous motor 6 is connected to a corresponding hydraulic fluid port of single-acting elevating ram 7 respectively.
The control setup of four single-acting elevating rams 7 of casing comprises a synchronous motor, casing (i.e. rubbish container) rises in melt pit, and be, by synchronous motor, synchro control is carried out to four single-acting elevating rams 7, realized the synchronization lifting of rubbish container by the accurate diverted liquid of synchronous motor (oil) medium to each single-acting elevating ram.
The utility model adopts high-low pressure by pass valve, and control lift-off pressures, load lifting cylinder stretches out initial stage 3-5 second (time is by electrically controlling) low pressure relief valve work, now system pressure cannot lifting rubbish container, then oil cylinder stretches out kiss the earth and rubbish container is motionless, eliminates ground surface error, synchronous start point; Switch to high-pressure overflow valve work after 5 seconds, rubbish container setting in motion, ensured by synchronous motor synchronous.
Be: primer fluid press pump 1 that hydraulic oil is through high-pressure overflow valve 2 oil return during specific works.Operation climb command, instruction sends initial stage 3-5 inner high voltage second by pass valve 2, high/low pressure cut-over valve 3, low pressure relief valve 4, change-over valve 5 simultaneously electric work, now low pressure relief valve 4 works, system pressure only has 1.5MPa, hydraulic oil enters elevating ram 13 through synchronous motor 6 shunting, elevating ram plunger moves downward kiss the earth, but because now system pressure only has 1.5MPa, oil cylinder produces hoisting force and is not enough to lifting rubbish container (casing), the oil cylinder stop motion of first kiss the earth, the oil cylinder of non-kiss the earth continues motion, until four oil cylinders all and earth surface, eliminate error gap, realize initial point synchronous, unnecessary oil overflows back fuel tank through low pressure relief valve 4.After 5 seconds, high/low pressure cut-over valve 3, low pressure relief valve 4 dead electricity, quit work, and this loop oil interrupts, and hydraulic oil cannot oil sump tank.Now high-pressure overflow valve 2 works, and system pressure is set as 20MPa, and hydraulic oil enters elevating ram 13 through synchronous motor 6 shunting, and oil cylinder internal pressure raises, and four elevating rams are synchronized with the movement, and ensures that the rising of rubbish container operates steadily.During operation decline instruction, change-over valve 5 obtains electric work, and hydraulic oil in oil cylinder is pushed back stream fuel tank through synchronous motor by rubbish container deadweight.Realize synchronous decline.So complete a circulation.
