Accompanying drawing explanation
Fig. 1 is working principle schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of power hydraulic system of the present utility model, comprise fuel tank 1, two hydraulic systems, two solenoid directional control valves 12, 14 and two brake fluid cylinder pressures 13, 15, it is characterized in that: fuel tank 1 is provided with air-strainer 2 above, each hydraulic system mainly contains oil adsorption filter 3 and 16, the oil hydraulic pump 5 and 18 that motor 4 and 17 drives and pipeline essence oil purifier 6 and 19, relief valve 7 and 20, oil adsorption filter 3 and 16 is between fuel tank 1 and oil hydraulic pump 5 and 18, the top of oil hydraulic pump 5 and 18 is provided with pipeline essence oil purifier 6 and 19 successively, relief valve 7 and 20, the outlet of relief valve 7 and 20 extend in fuel tank 1 by oil pipe, high-pressure oil pipe 8 and 21 outlet port of each hydraulic system is provided with high-pressure ball valve 9 and 22, be connected with third high pressuring oil pipe 10, third high pressuring oil pipe 10 two ends are connected with two solenoid directional control valves, 12,14 and two brake fluid cylinder pressures 13,15 respectively, and third high pressuring oil pipe 10 is provided with pressure gauge 11.
Described pressure gauge 11 is shatter-proof formula pressure gauge.
Described solenoid directional control valve 12,14 and motor 4,17 are flame-proof type structure.
Adopt technique scheme, generally only a hydraulic system is used during each use, another hydraulic system is standby hydraulics, should first be closed by the high-pressure ball valve 22 of a hydraulic system B when needing use, uses the high-pressure ball valve 9 of hydraulic system A to open.When motor 4 is energized, oil hydraulic pump 5 operates, hydraulic oil in fuel tank 1 is clipped to solenoid directional control valve (1) 12 and solenoid directional control valve (2) 14 through oil adsorption filter 3, pipeline essence oil purifier 6, high-pressure ball valve 9 points, brake fluid cylinder pressure (1) 13 and brake fluid cylinder pressure (2) 14 are worked, the brake slipper of braking device departs from Brake drum, equipment can bring into operation, understand oil hydraulic pump runnability by observing pressure gauge 11, unnecessary hydraulic oil is flow in fuel tank 1 from the outlet of relief valve 7 by oil pipe.
When equipment needs out of service, solenoid directional control valve (1) 12 and solenoid directional control valve (2) 14 change oil inlet and outlet respectively, the filler opening of brake fluid cylinder pressure (1) 13 and brake fluid cylinder pressure (2) 15 becomes oil outlet, make brake fluid cylinder pressure (1) 13 and brake fluid cylinder pressure (2) 15 quick pressure releasing, make brake slipper pack tightly Brake drum equipment fast out of service.
If hydraulic system A needs to be serviced or keeps in repair, when the equipment that do not affect runs, the motor 17 of hydraulic system B can be energized, oil hydraulic pump 18 opens high-pressure ball valve 22 after operating again, and then close the high-pressure ball valve 9 of hydraulic system A, finally close hydraulic system motor 4 power supply, can need to be serviced hydraulic system A or keep in repair.If safeguard hydraulic system B or maintenance repetition aforesaid operations method.
