Abstract
An elevator pin anti-drop protection device belongs to the technical field of underground operation of oil and gas fields. The pin anti-falling stop lever is connected with the pin shaft in a welding mode, the pin shaft is connected with the bolt main body in an inserting mode, one end of the spring pressing strip is fixed to the pin main body, the other end of the spring pressing strip is fixed to the anti-falling stop lever, and the pin main body is provided with a safety rope hole. The utility model has the advantages that the jack is inserted with the elevator bolt at borehole operation tripping pipe post in-process, and the spring layering pushes down pin anti-drop pin and realizes fixing bolt, blocks rings and drops from the elevator, reduces operation workman intensity of labour, 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:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Detailed description of the invention
Obviously the many modifications and variations that, those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1; a kind of lift-sub pin anti-loosening protector; pin slip-off preventing pin 2 is welding with pin axle 3 connected modes; the grafting that is connected to of pin axle 3 and latch main body 1; 4 one of band springs are fixed in pin main body 1; one is fixed on 2 anticreep pins, has safety rope hole 5 in pin main body 1.
When trip-out, transfer coaster to well head, suspension ring are hung in elevator ear, insertion elevator hangs up pin safety rope pin slip-off preventing pin is mixed out, pin main body is inserted in elevator jack, unclamp pin slip-off preventing pin, completed the fixing of anticreep pin, the operation such as can start to make a trip.
Embodiment 2: as shown in Figure 1; a kind of lift-sub pin anti-loosening protector, pin slip-off preventing pin 2 is made one with pin axle 3, and a groove is arranged at pin slip-off preventing pin 2 bottoms; on pin axle 3, be tied with return spring one and be fixed on pin axle, other end is fixed on anticreep pin 2.Pin axle 3 inserts in pin main body 1, and pin main body can be rotated around pin axle 3, and pin main body 1 upper end is drilled with safety rope hole.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
