Description of drawings:
Fig. 1 is a front view of the present invention, and Fig. 2 is 1 the left view of figure, and Fig. 3 is the spiral body partial enlarged drawing of Fig. 1, and Fig. 4 is the hydraulic efficiency elevation structure system schematic.
The specific embodiment:
In conjunction with above-mentioned accompanying drawing the present invention is described in detail, with spiral body 4 above wheeling mechanism 2 on be provided with fuel tank 21, gear type pump 19, two parallel hydraulic actuating cylinders 6 and accumulators 24, on the oil circuit between hydraulic actuating cylinder and the gear type pump 7, be provided with 2/2-way hand change over valve 18, check valve 16,3-position 4-way hand change over valve 15, governor valve 13, balance cock 11 and hydraulic control one-way valve 9 successively.Be provided with afflux flow divider valve 8 on the epicoele of hydraulic actuating cylinder and the oil circuit 14 between the 3-position 4-way hand change over valve, an end of hydraulic control oil circuit 10,12 is connected with hydraulic control one-way valve with balance cock respectively, and the other end is connected with oil circuit 14.Between the oil circuit 7 between accumulator 24 and gear type pump and the 2/2-way hand change over valve, be connected with an oil circuit 22, this oil circuit is provided with check valve 23, one end of oil circuit 26 is connected with oil circuit 22 between accumulator and the check valve 23, the other end is connected with oil circuit 7 between check valve 16 and the 3-position 4-way hand change over valve, and this oil circuit 26 is provided with 2/2-way hand change over valve 25.One end of by pass valve 20 is connected with fuel tank, and the other end is connected with accumulator oil circuit 22 with oil circuit 7 between gear type pump and the 2/2-way hand change over valve, is provided with pressure relay 17 on oil circuit 22.Safer for lifting process, limes superiors, smallest limit travel switch can be set, the mouth of pressure relay is electrically connected with by pass valve.Water spraying mechanism 5 (see figure 2)s can be set on the spiral body, prevent the dust from flying contaminated environment.Above-mentioned accumulator is exactly a high pressure vessel, as long as the pressure can satisfy energy storage the time requires.The present invention can be provided with central controller, and change 2/2-way hand change over valve and 3-position 4-way hand change over valve into electromagnetic valve, the mouth of the pressure relay 17 that is provided with on the oil circuit 22 is connected with the input end of 2/2-way solenoid directional control valve, it is opened connect oil circuit 7, realize automatic guidance or the long-range purpose of controlling.
The principle of work of lifting mechanism of the present invention is, when lorry enters the stock ground and needs discharging, before 4 risings of spiral body or decline discharging work, earlier 2/2-way hand change over valve 18 is in right position, oil circuit 7 is cut off, after the gear type pump work, earlier to the accumulator fuel feeding, when treating that its pressure reaches scheduled pressure value, make 2/2-way hand change over valve 18 be in position, a left side, when the 3-position 4-way hand change over valve is in right position, pressure oil will be entered the cavity of resorption of hydraulic actuating cylinder by oil circuit 7, piston rises and drives lifting mechanism 3 risings, spiral body 4 is raise, and the oil in the hydraulic actuating cylinder epicoele is got back to fuel tank through afflux flow divider valve and 3-position 4-way hand change over valve at this moment, and the afflux flow divider valve can guarantee the same moved further of the piston of two hydraulic actuating cylinders.When needs spiral body descends, should make the commutation of 3-position 4-way hand change over valve to position, a left side, this moment, pressure oil entered oil circuit 14 through the epicoele of afflux flow divider valve to hydraulic actuating cylinder through the 3-position 4-way hand change over valve, and piston moves down the spiral body is descended.Operating personal can make the 3-position 4-way hand change over valve return to midway location according to the signal of upper and lower limit travel switch, and pressure oil was cut off and can not enters in oil circuit 7 and the oil circuit 14 this moment, and flowed in the fuel tank, and the spiral body is locked in this position reliably.Spiral body front and back and left and right sidesing shifting in the plane is the (see figure 1) of finishing by traveling mechanism of the larger traveller 1 and wheeling mechanism 2.The effect of by pass valve 20 is, when oil piping system breaks down when causing oil pressure to raise reaching certain pressure, opens automatically, and high pressure oil is got back to the purpose that fuel tank is realized pressure release through this valve.When power outage occurring in discharge process, can handle 2/2-way hand change over valve 25, make oil circuit 22 and oil circuit 7 connections, the oil pressure of accumulator rises oil cylinder match alive and drives the rising of spiral body, and vehicle can leave the scene.
