Abstract
A kind of lift-sub pin anti-loosening protector, belongs to oil-gas field downhole operation technical field.Pin slip-off preventing pin and pin axle are connected to welding, pin axle and latch main body be connected to grafting, one of band spring is fixed in pin main body, band spring other end is fixed on anticreep pin, has safety rope hole in pin main body.The utility model has the advantages that in underground work and rise in lower tubular column process elevator latch is inserted to jack, band spring is pushed down pin slip-off preventing pin and is realized Fixed latches, stops that suspension ring come off from elevator, reduces operating worker labour intensity, ensures safety in production.
Description
Technical field
The utility model relates to a kind of lift-sub pin anti-loosening protector, belongs to oil-gas field downhole operation technical field.
Background technology
Rise in lower tubular column process at oil-gas field downhole operation at present, suspension ring hang on elevator, on elevator, insert safety pin and prevent that suspension ring from deviating from from elevator, the general safety pin for hanging gripper adopting is all with and is magnetic, and after using for a long time, magnetic weakens, human negligence and failure to inspect, in the process of making a trip, safety pin is deviate from, and is easy to cause suspension ring to deviate from from elevator, not only can fall to bore and cause down-hole accident, and can bring personal injury accident to operating personnel, hide great potential safety hazard.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of lift-sub pin anti-loosening protector.
A kind of lift-sub pin anti-loosening protector; pin slip-off preventing pin and pin axle are connected to welding, pin axle and latch main body be connected to grafting, one of band spring is fixed in pin main body; band spring other end is fixed on anticreep pin, has safety rope hole in pin main body.
The beneficial effect of advantage of the present utility model and generation is:
1, this device adopts pin slip-off preventing stop lever, ensures the work of elevator effective and safe.
2, package unit volume is little, light, simple.
3,, in the process of making a trip, well head work is inserted lift-sub pin rear spring press strip and is driven slip-off preventing pin, makes pin fastening elevator, has greatly increased the safety of elevator.
The utility model has the advantages that in underground work and rise in lower tubular column process elevator latch is inserted to jack, band spring is pushed down pin slip-off preventing pin and is realized Fixed latches, stops that suspension ring come off from elevator, reduces operating worker labour intensity, ensures safety in production.
Brief description of the drawings
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, does not form to improper restriction of the present utility model, wherein:
