Abstract
The utility model discloses a pair of hydraulic well repairing power tongs, and aims to solve the problems of the presence of potential safety hazard and complex operation in a hydraulic well repairing power tongs protection plate during well repairing on an oil field. The pair of hydraulic well repairing power tongs comprises a tongs body 1 and a protection plate 2, wherein the protection plate 2 is arranged beside a hinge shaft; the outer surface of the tongs body 1 is provided with two pin shaft bases 4; pin shafts 3 are inserted into the pin shaft bases 4; the pin shafts 3 are wounded with torsion springs 5; one end of each torsion spring 5 is clamped outside the protection plate 2, and the other end of each torsion spring 5 is clamped outside the tongs body 1. The pair of hydraulic well repairing power tongs has the beneficial effects that by the adoption of the technical scheme adopted for the pair of hydraulic well repairing power tongs, the projection plate is in a closed state at ordinary times under the actions of the torsion springs, and an oil pipe can be placed into a jaw by pulling the protection plate away without other operation. The pair of hydraulic well repairing power tongs is easy and convenient to operate, the torsion springs are prevented from falling off easily, and high safety performance is achieved.
Description
Technical field:
The utility model relates to field produces workover tool field, is specifically related to a kind of hydraulic pressure well repairing power pliers.
Background technology:
In oil well repairing operation, the screw thread of upper, emptying pipe and drilling tool is maximum, the hard work amount of operator in well workover process, hydraulic power tongs be utilize workover rig power operated mechanically, unload screw thread instrument, can greatly alleviate well workover workman's labour intensity, avoid or reduce the generation of injury accident.The backplate of current hydraulic pressure well repairing power pliers is to hang on the body of hydraulic power tongs and above backplate with Compress Spring, open at every turn and need to backplate be opened with hand, oil pipe is put into after jaw, with hand, backplate is shut again, when reality is used, we find to be used for the Compress Spring of switch guard board and are easy to come off, vibrations when backplate is along with work after coming off can be opened, easily cause security incident, in addition, backplate only need to be opened when oil pipe is put into jaw, all the other time all need to close, current backplate is opened to close all needs manual operation, complex operation.
Utility model content:
In order to solve oil well, do the used time, there is potential safety hazard in hydraulic pressure well repairing power pliers backplate, the problem of complex operation, the utility model provides a kind of hydraulic pressure well repairing power pliers, and this kind of hydraulic pressure well repairing power pliers utilizes torsionspring to close backplate, is not easy to come off, simple to operate, security performance is high.
The technical solution of the utility model is: this kind of hydraulic pressure well repairing power pliers comprises pincers body and backplate, on backplate hinge axis side, clamp this external surface and be provided with two axis pin bases, in axis pin base, be installed with bearing pin, on bearing pin, be wound with torsionspring, one end of torsionspring is stuck in backplate outside, and the other end of torsionspring is stuck in pincers body outside.
The utlity model has following beneficial effect: this kind of hydraulic pressure well repairing power pliers is by adopting such scheme, effect due to torsionspring, backplate is at ordinary times in closed condition, when needs are put into jaw by oil pipe, pull open backplate oil pipe is put into, without other operations, easy and simple to handle, torsionspring difficult drop-off, security performance is good.
Accompanying drawing explanation:
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is partial top view of the utility model part 5.
In figure 1, pincers body; 2, backplate; 3, bearing pin; 4, axis pin base; 5, torsionspring.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail: by Fig. 1 in conjunction with shown in Fig. 2, this a kind of hydraulic pressure well repairing power pliers comprises pincers body 1 and backplate 2, on backplate 2 hinge axis sides, pincers body 1 external surface is provided with two axis pin bases 4, in axis pin base 4, be installed with bearing pin 3, on bearing pin 3, be wound with torsionspring 5, one end of torsionspring 5 is stuck in backplate 2 outsides, and the other end of torsionspring 5 is stuck in pincers body 1 outside.
Due to the effect of torsionspring, backplate, at ordinary times in closed condition, when needs are put into jaw by oil pipe, pulls open backplate oil pipe is put into, without other operations, easy and simple to handle, torsionspring difficult drop-off, and security performance is good.
