The specific embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1 and 2, the utility model mainly comprises hydraulic reservoir 1, and hydraulic reservoir 1 connects hydraulic gear pump 3 by oil suction pipe 7, and hydraulic gear pump 3 connects hydraulic lifting valve 4 by oil outlet pipe 10.
Hydraulic lifting valve 4 connects hand-operated hydraulic valve 5 by control oil pipe 15, and hand-operated hydraulic valve 5 connects a plurality of hydraulic rams 6 one by one by a plurality of transport pipe 16, and each hydraulic ram 16 is controlled lifting and the decline in a compartment.
Hydraulic lifting valve 4 is fastened on the oil return filter core 2 on hydraulic reservoir 1 by oil return pipe 17.
On hydraulic lifting valve 4, by the first tracheae 18, connect hand-operated pneumatic control valve 12, hand-operated pneumatic control valve 12 connects external gas source.
On hydraulic lifting valve 4, by the second tracheae 19, connect shuttle valve 9, shuttle valve 9 connects a plurality of limit valves 8 one by one by a plurality of gas pipings 20, each limit valve 8 is by the common electromagnetic gas valve 11 that connects of a muffler 21, and electromagnetic gas valve 11 connects hand-operated pneumatic control valve 12 by the 3rd tracheae 22.
During work, the hydraulic oil in hydraulic reservoir 1, by hydraulic gear pump 3 sucking-offs, becomes high pressure oil after the effect through hydraulic gear pump 3 and enters in hydraulic lifting valve 4.When hydraulic ram 6 need to be realized lifting action, handle hand-operated pneumatic control valve 12, handle is placed in to lift location, pressurized air enters in electromagnetic gas valve 11 through controlling gas circuit.Select the electromagnetic switch of electromagnetic gas valve 11, make the left position of electromagnetic gas valve in running order, now pressurized air enters in limit valve 8 through controlling air path part.Due under limit valve 8 normalities in on-state, pressurized air can directly enter in shuttle valve 9 through after limit valve 8, enters in the lifting mouth of hydraulic lifting valve 4 afterwards by controlling gas circuit, hydraulic lifting valve 4 is in lifting state.Handle the bar handle of hand-operated hydraulic valve 5, make the left position of this valve in running order, high pressure oil enters in hydraulic ram 6, has realized the lifting action of hydraulic ram 6.After the position-limited lever of limit valve 8 is compressed, the left chamber of limit valve is in running order, and the pressurized air of controlling in gas circuit is cut off, and now the valve rod in hydraulic lifting valve 4 returns to meta under the effect of spring force, high pressure oil is closed in hydraulic lifting valve 4, hydraulic ram 6 stop motions; When hydraulic ram 6 need to land, handle hand-operated pneumatic control valve 12, handle is placed in to lowering position, pressurized air directly enters in the port for drawdown of hydraulic lifting valve 4 through controlling gas circuit, now hydraulic ram and hydraulic reservoir are realized directly and being connected, high pressure oil is through directly entering hydraulic reservoir after hand-operated hydraulic valve 5, hydraulic lifting valve 4 and oil return filter core 2, and oil cylinder completes a lifting cycle.Merging by hydraulic circuit and control gas circuit, has realized the multi-control function of a valve, thereby has completed smoothly the lifting action in the different compartments of self-discharging train.
