Accompanying drawing explanation
fig. 1 is structural representation of the present invention.
Embodiment
below in conjunction with drawings and Examples, the present invention is further illustrated, but not as the foundation limited the present invention.
embodiment: high-altitude, gardens clipping device, as shown in Figure 1, comprise multistage lifting hydraulic cylinder 1, multistage lifting hydraulic cylinder 1 is provided with platform, platform is provided with trimming tool and operator, the rear end of multistage lifting hydraulic cylinder 1 is connected with Pilot operated check valve 2, Pilot operated check valve 2 is connected with three-position four-way electromagnetic directional valve 3, and Pilot operated check valve 2 is held with the P of three-position four-way electromagnetic directional valve 3 and is connected, the A end of three-position four-way electromagnetic directional valve 3 is connected with high-pressure gear pump 4, the B end of three-position four-way electromagnetic directional valve 3 is connected with throttle valve 5, and throttle valve 5 is connected with fuel tank 6; Described high-pressure gear pump 4 is also connected with the first two-position four-way solenoid directional control valve 7, and high-pressure gear pump 4 is held with the A of the first two-position four-way solenoid directional control valve 7 and is connected, the B end of the first two-position four-way solenoid directional control valve 7 is connected with fuel tank 6, the P of the first two-position four-way solenoid directional control valve 7 holds the rod end being connected with tool feeding oil hydraulic cylinder 8 to be connected, and tool feeding oil hydraulic cylinder is provided with trimming tool 9; The T end that the rear end of tool feeding oil hydraulic cylinder 8 is connected with the first two-position four-way solenoid directional control valve 7 is connected; Described Pilot operated check valve 2 is also connected with the second two-position four-way solenoid directional control valve 10, second two-position four-way solenoid directional control valve 10 and is connected with fuel tank.Described high-pressure gear pump 4 is also connected with pressure gauge 11.Described high-pressure gear pump 4 goes back relief valve 12, and relief valve 12 is connected with fuel tank 6.Position limit switch 13 is also provided with at the rod end of tool feeding oil hydraulic cylinder 8.
working principle: when pruning platform rising, start high-pressure gear pump, electromagnet 2YA, 4YA energising makes three-position four-way electromagnetic directional valve and the first two-position four-way solenoid directional control valve switch to right position, and the pressure oil of high-pressure gear pump makes trimming tool stretch out through the rear end that the first two-position four-way solenoid directional control valve enters tool feeding oil hydraulic cylinder to prune; The bottom that pressure oil enters multistage lifting hydraulic cylinder through three-position four-way electromagnetic directional valve simultaneously drives multistage lifting hydraulic cylinder to rise.Electromagnet 2YA power-off makes three-position four-way electromagnetic directional valve multiple to meta, and high-pressure gear pump is shut down by the H type meta off-load of three-position four-way electromagnetic directional valve, makes multistage lifting hydraulic cylinder be in high-order working state.Now by controlling, electromagnet 4YA obtains, power-off, and about controlling the first two-position four-way solenoid directional control valve, position switches, and drives stretching out and indentation of tool feeding oil hydraulic cylinder.
after work completes, when pruning platform decline, electromagnet 1YA is energized makes three-position four-way electromagnetic directional valve switch to left position, 3YA energising makes the second two-position four-way solenoid directional control valve switch to left position, Pilot operated check valve opened by pressure oil, and the pressure oil of multistage lifting hydraulic cylinder, through Pilot operated check valve, three-position four-way electromagnetic directional valve and throttle valve, finally flows to fuel tank, realize the decline of multistage lifting hydraulic cylinder, owing to being regulated the speed and time that control to decline by the throttle orifice aperture of throttle valve.The present invention achieves the lifting of platform and the feeding of cutter by a set of hydraulic power supply, and owing to being realized the decline of multistage lifting hydraulic cylinder by throttle valve, therefore substantially increases stationarity during decline.On the other hand, owing to being adopt the gravity on platform to press down when declining, because power when this reducing decline uses, energy loss is greatly reduced.
