The utility model content
The purpose of this utility model is: a kind of friction commutation oil pumper tool of unloading is provided, can tightens polished rod, and help operating hydraulic jack, finally can finish the unloading of friction commutation oil pumper, improve security performance, alleviate labor strength.
The technical solution adopted in the utility model is: friction commutation oil pumper tool of unloading, mainly form by left fixture block, back-up block, pivot pin, contiguous block, right fixture block, latch segment, nut, left side fixture block and right fixture block are cuboid, a side at left fixture block and right fixture block has the semicircular arc slips respectively, the circular slips of relative latter two semicircular arc slips with right fixture block of left fixture block.It is characterized in that: the two ends at left fixture block and right fixture block have transverse concave groove respectively.In the transverse concave groove of the left end of the right-hand member of left fixture block and right fixture block contiguous block is arranged, at the right-hand member of left fixture block and the left end of right fixture block the axis hole parallel with the semicircular arc slips arranged respectively, a pivot pin is arranged respectively in the axis hole, two pivot pins pass the through hole at contiguous block two ends.Left side fixture block and right fixture block can be realized opening or closing by pivot pin and contiguous block.In the groove of the right-hand member of right fixture block, latch segment is arranged, the right-hand member of right fixture block has the axis hole parallel with the semicircular arc slips, a pivot pin is arranged in the axis hole, pivot pin passes the axis hole of latch segment one end, latch segment can rotate around pivot pin, the other end of latch segment has external screw thread, on the other end external screw thread of latch segment nut is arranged.After left side fixture block was relative with right fixture block, latch segment can snap in the groove of left fixture block left end, screws nut left fixture block and right fixture block are fixed together.Two rectangle back-up blocks are arranged respectively on plane on left fixture block and the right fixture block.Polished rod is put into the semicircular arc slips of left fixture block and right fixture block, after left fixture block and the right fixture block relative fixed, can tighten polished rod.Can insert hydraulic jack in the hole on left side fixture block and the right fixture block between the rectangle back-up block on plane.
The height of described rectangle back-up block is 10～50 millimeters.
Described rectangle back-up block is to be welded on the last plane of left fixture block and right fixture block.
Its operating principle is:
Consult Fig. 3.Utilize friction commutation oil pumper tool of unloading to block polished rod.Utilize in the hole between the very heavy insertion back-up block 3 of dedicated hydraulic, fastening nut 8 is slowly played (safe lifting altitude is 35mm-40mm) with dedicated hydraulic is very heavy, until the upper clip unloading with the polished rod eye place.
The beneficial effects of the utility model: the utility model friction commutation oil pumper tool of unloading, can finish the unloading of friction commutation oil pumper, improve security performance, alleviate labor strength, rate when having saved the consumption of human and material resources and having improved the oil pumper running has improved crude output.The unloading of former method needs two people to spend half an hour to finish, only need now can finish once personal five minutes.
