Description
Technical field:
The utility model relates to the oil pumper mechanical field, is specifically related to a kind of pumping unit control device that prevents maloperation.
Background technology:
Oil pumper is a kind of machinery equipment of recover petroleum, makes oil go out well by the way of pressurizeing.When the oil pumper upstroke, the oil pipe elastic shrinkage moves upward, and the driving mechanical block-relief oil production device moves upward, and the bump sliding sleeve produces vibration; Simultaneously, the copper current only valve cuts out, and reducing piston assembly shutoff oil is when the oil pumper down stroke, and the oil pipe elastic elongation moves downward, and the driving mechanical block-relief oil production device moves downward, and the bump sliding sleeve produces vibration; Simultaneously, reversed check valve is partly closed, and the reducing piston assembly is shutoff oil jacket ring shaped oil passage still, makes the reversed check valve lower zone form the higher-pressure region, and this motion produces a kind of reverse impact force to the oil flow channel in the stratum again.
Referring to Fig. 1, at present the operating means of oil pumper in use because device without limits, everyone can operate, and causes easily maloperation, and is dangerous during use.
The utility model content:
The purpose of this utility model provides a kind of pumping unit control device that prevents maloperation, and it is difficult for causing maloperation, uses safety, and is easy and simple to handle.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises fluted disc 1, bayonet lock 2, action bars 3, handle 4, pull bar 5, spring 6, it also comprises locking device 7, card adapter plate 8, one end of the upper end of action bars 3 and handle 4 is hinged, the upper end of the other end of handle 4 and pull bar 5 is hinged, the lower end of pull bar 5 is connected with card adapter plate 8, the lower end of card adapter plate 8 is connected with bayonet lock 2, bayonet lock 2 is arranged in the spacing hole of action bars 3 downsides, bayonet lock 2 matches with latch on the fluted disc 1, locking device 7 is welded on the downside of action bars 3, spring 6 is arranged on the inboard of action bars 3, and an end of spring 6 is connected with handle 4, and its other end is connected with action bars 3.
The inside of described locking device 7 is provided with lock core 7-1, and lock core 7-1 and card adapter plate 8 upper groove 8-1's is corresponding.
The utility model in use, operating personnel are by special spanner rotary locking cylinder 7-1, lock core 7-1 is broken away from groove 8-1, by handle 4 bayonet lock 2 pulling force are thrown off latch on the fluted disc 1 again, operate, operation is over, and lock core 7-1 is sticked in the groove 8-1 again, guaranteed that other staff can maloperation, guaranteed the safety of operation.
The utility model is difficult for causing maloperation, uses safety, and is easy and simple to handle.
