Abstract
The utility model relates to a special device for regulating the stroke of an oil pump used for the oil extraction of a sucker rod pump, which comprises a pulling force chain 2, an angle bend 3, a regulating nut 4, a chain fixed pin 5, a screw rod 9, a regulating pipe, etc., wherein the pulling force chain 2 surrounds a connecting rod 1 of an oil pumping unit and is connected with the chain fixed pin 5, the angle bend 3 is arranged on the end part of the screw rod 9, the regulating nut 4 is arranged on the screw rod 9, and a shim 7 is arranged on the regulating nut 4. The shim 7 is screwed with a cover cap 8, and the screw rod 9 is arranged in the regulating pipe. A connecting rod pin can be pushed out of an old hole by the strength of the screw rod when the stroke of the oil pump is regulated. When the connecting rod achieves the position of a new hole, the connecting rod can be pulled into the new hole and is matched with a readymade pneumatic tool by the strength of the screw rod, and the mechanization of the stroke regulation of the oil pump is realized. The work intensity of the workers is relieved, and the safety in production is ensured simultaneously.
Description
Relate to the field
The utility model relates to oil exploitation technology, specifically, is to be used for the oil pumper accent stroke isolated plant that the beam hanger pump recovers the oil.
Background technology
Beam hanger recovers the oil and requires used oil pumper to have different strokes to select, to adapt to the different oil well pumps that require.Therefore, if for the oil well pump under each with last time desired stroke different, must adjust the oil pumper stroke so, to satisfy the job requirement of oil well pump.
At present, it is cumbersome thing that oil pumper is transferred stroke at the scene, the link pin nut is beaten pine with sledgehammer, backs out nut then, again with sledgehammer, strike rod the taper link pin got tie rod holes.With bottle gouard moved by hands pulling oil pumper walking beam, make link pin aim at the hole that will adjust, sledgehammer is squeezed into again ... a series of like this manually-operated makes accent extremely require great effort towards work, and exists potential safety hazard, we can say, finish the stroke work of transferring without any special tool at present.
Technology contents
The purpose of this utility model is to provide a kind of instrument in order to the work of solution oil pumper bar stroke of special use, that is oil pumper is transferred the stroke isolated plant.
The utility model is achieved in that
Comprise pulling force chain 2, angle bend 3, adjust nut 4, chain steady pin 5, chain retainer ring 6, pad 7, by cap 8, screw mandrel 9, adjustable pipe 10, boosting-rod hole 11, pulling force chain 2 is trapped among on the oil pumper connecting rod 1, chain steady pin 5 is arranged on the chain retainer ring 6, pulling force chain 2 is connected with chain steady pin 5 pins, angle bend 3 places the end of screw mandrel 9, and the nut 4 of adjustment is arranged on the screw mandrel 9, and adjusting on the nut 4 has pad 7, be screwed with on the pad 7 by cap 8, screw mandrel 9 is arranged in the adjustable pipe 10.
The utility model also adopts following technical scheme:
Chain retainer ring 6 is screwed to be adjusted on the nut 4.
Boosting-rod hole 11 is arranged on the adjustable pipe 10.
120 ° of angles are adopted in angle bend 3.
Pulling force chain 2 adopts 1 group of above carrier bar to be connected to form.
It is the trapezoidal thread of 3mm that screw mandrel 9 can adopt pitch.
Advantage of the present utility model is: it can be when oil pumper be adjusted stroke, strength with screw mandrel is released old hole with link pin, and when link pin reaches new hole position, draw in new hole with the strength of screw mandrel and be used ready-made pneumatic tool again, just can realize the mechanization of oil pumper accent stroke work, alleviate working strength of workers, guaranteed safety in production simultaneously.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Concrete enforcement
As shown in drawings, pulling force chain 2 surrounds oil pumper connecting rod 1, and locking chain steady pin 5, and screw and adjust nut 4, tension pulling force chain 2, like this, angle bend 3 is just tightly embraced oil pumper connecting rod 1 with pulling force chain 2.The top and the bottom operation of this device is identical, after boosting-rod inserts afterburning hole 11, screw boosting-rod, because the different screw mandrels 9 of the rotation direction of 9 two screw threads of screw mandrel just can screw out or screw in the adjustable pipe 10, make oil pumper connecting rod 1 extrapolated, or inwardly draw in, the link pin that links to each other with oil pumper connecting rod 1 just can be pushed out old hole, or be drawn into new hole, finish the task of transferring stroke.
Angle bend 3 adopts 120 ° of angles can embrace the connecting rod of different-diameter.
Pulling force chain 2 adopts many group carrier bars to be connected to form, and can very firmly embrace connecting rod, and not produce slip.
It is the trapezoidal thread of 3mm that screw mandrel 9 can adopt pitch, and strength is big like this, and durable.
