Description
Technical field
This utility model relates to a kind of sleeve puller, is specifically related to a kind of crank pin for pumping unit lining sleeve puller.
Background technology
At present cause change crank pins lining main cause: rod-pumped well crank pins, the damage of crank-pin shuttlecock；Pin is improper with lining taper fit；Impurity is had in lining during dress pin；Change crank pins when taking old lining simultaneously, extremely difficult, often have lining to get rusty the phenomenon not taken to get off；
When changing at present the operation of crank pins lining, the two bit manipulation personnel of need enter in support, and wherein a people uses band iron, inflexible hands, bolt etc., the sub-limit of top cover, holds up bolt etc., and another people is pounded with sledgehammer.Dare not pound with strength and hold meaning during operation and pound hands, the most dangerous but also impact rate when driving a well.Running into lining to take to get off, use fire weldering to cut, both increased cost and had an effect on oil well production, crank hole surface is also damaged sometimes, causes this stroke hole not use, and for the problems referred to above, ad hoc meter this utility model is solved.
Utility model content
The purpose of this utility model is to provide one can simplify operating process, reduces the crank pin for pumping unit lining sleeve puller of security risk.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of crank pin for pumping unit lining sleeve puller, including A-frame, supporting leg, balancing frame, bearing hold-doun nut, screw mandrel head, connect steady pin, regulating nut, screw mandrel and thrust bearing, screw mandrel upper end is provided with screw mandrel head, screw mandrel centriciput is provided with through hole in the horizontal direction, screw mandrel top connects A-frame, A-frame includes rack body and connecting portion, 3 connecting portions it are evenly distributed with on rack body, connecting portion is vertically provided with connecting hole, connecting portion is provided with pin-and-hole in the horizontal direction, A-frame connects supporting leg, screw mandrel bottom connects balancing frame, balancing frame is respectively provided on two sides with thrust bearing, screw mandrel bottom is provided with bearing hold-doun nut.
As the further improvement of above-mentioned technology, the threaded A-frame in described screw mandrel top.
As the further improvement of above-mentioned technology, described rack body cross section is circular configuration.
As the further improvement of above-mentioned technology, described A-frame connects supporting leg by connecting hole and connection steady pin.
As the further improvement of above-mentioned technology, described supporting leg bottom is provided with regulating nut.
Compared with prior art, the beneficial effects of the utility model are: the operation of more resleeve only needs 1 people to enter Framework of Pumping Unit 3 minutes, use screw mandrel to carry out strand to draw, save time safety, swift and convenient to operate, do not result in damage, more resleeve operation security risk is low, it is possible to meet pulling tension requirements, it is ensured that the normal use of lining sleeve puller, shorten the time of employee's more resleeve, reduce labor intensity, and greatly reduce security risk when employee operates, reduce cost, decrease and take out the yield effect caused because stopping, there is certain economic benefit.
