Fig. 2 is the structural representation of hydraulic power unit in a kind of pumping unit maintenance unit with buffer function of the utility model.
In figure, 1. oil hydraulic pump, 2. one-way valve, 3. fuel tank, 4. three position four-way directional control valve, 5. adjustable one-way throttle valve, 6. oil pipe, 7. relief valve, 8. support beam, 9. supporting hinged seat, 10. damping spring, 11. oil hydraulic cylinders, 12. piston rods, 13. spherical hinge joint chairs, 14. struts, 15. walking beams, 16. hydraulic power units.
Embodiment
Below in conjunction with embodiment, the utility model is elaborated.
The utility model provides a kind of pumping unit maintenance unit with buffer function, as depicted in figs. 1 and 2, comprise the oil hydraulic pump 1 connecting successively, one-way valve 2 and three position four-way directional control valve 4, between one-way valve 2 and three position four-way directional control valve 4, be provided with relief valve 7, three position four-way directional control valve 4 is connected by lower half portion of oil pipe 6 and oil hydraulic cylinder 11, on this oil pipe 6, be provided with adjustable one-way throttle valve 5, upper half part of the oil outlet of three position four-way directional control valve 4 and oil hydraulic cylinder 11 is connected, lower half portion of oil hydraulic cylinder 11 is provided with damping spring 10, upper half part of oil hydraulic cylinder 11 is provided with piston rod 12, oil hydraulic cylinder 11 is connected with pumping unit support beam 8, support beam 8 is connected with walking beam 15, the lower end of walking beam 15, directly over oil hydraulic cylinder 11, be provided with spherical hinge joint chair 13, the middle and upper part of oil hydraulic cylinder 11 is connected with pumping unit support beam 8 by the strut 14 with spring, on support beam 8, be fixed with bloster hinge joint chair 9, bloster hinge joint chair 9 is connected with the lower end of oil hydraulic cylinder 11.
During use, in the situation that pumping unit runs well, adjustable one-way throttle valve 5 Flow-rate adjustment are to minimum, when the unexpected mistake of pumping unit front end is carried, pumping unit afterbody falls, when the spherical hinge joint chair 13 on walking beam 15 touches the piston rod 12 in oil hydraulic cylinder 11, piston rod 12 bounces back rapidly, under the effect of damping spring 10, pumping unit afterbody slows down and, simultaneously under adjustable one-way throttle valve 5 effects, hydraulic oil slowly refluxes, oil hydraulic cylinder 11 is slowed down, reached buffering object, thereby play, prevent from smashing pumping unit and the effect eliminating safe hidden trouble.
When pumping unit breaks down while needing repairing, adjustable one-way throttle valve 5 Flow-rate adjustment are extremely maximum, hydraulic oil, under the effect of oil hydraulic pump 1, by one-way valve 2, enters 4 left functions of three position four-way directional control valve, then by adjustable one-way throttle valve 5, the piston rod 12 promoting in oil hydraulic cylinder 11 moves upward, and then stretches out oil hydraulic cylinder, and top is to spherical hinge joint chair 13, promote walking beam on pumping units 15 motions, make front horse head move downward desired location.After pumping unit has keeped in repair, start the right position of three position four-way directional control valve function, hydraulic oil is by oil pipe 6, oppositely promoting piston rod 12 regains, piston rod 12 tops are separated from walking beam on pumping units 15, and hydraulic oil, by adjustable one-way throttle valve 5 and three position four-way directional control valve 4, is back to fuel tank 3, integrated hydraulic cylinder 11 is not interfered the work of pumping unit, can not bump with walking beam on pumping units 15.
A kind of pumping unit maintenance unit with buffer function of the utility model; in this device, relief valve plays level pressure overflow effect and safety protection effect; adjustable restrictive valve in in-oil cylinder damping spring and loop plays the effect of " dual " shock absorbing power; thereby the potential safety hazards such as pumping unit is smashed have been eliminated; in addition when pumping unit needs repairing; because tail is overweight thereafter; need to use hydraulic pressure installation tail boom jack-up thereafter; play the effect of support, also greatly reduce staff's labor intensity and the risk of existence simultaneously.
