Having described the basic principles of the present utility model, various non-limiting embodiments of the utility model are described in detail below. Any number of elements in the figures are for illustration and not limitation, and any naming is used for distinction only and not for any limiting sense.

The principles and spirit of the present utility model are explained in detail below with reference to several representative embodiments thereof.

As shown in fig. 1 to 3, the well repairing power tongs convenient to control provided by the utility model comprise a bracket 1, a driving system, two clamping claws 3 and a box body 6, wherein the driving system is arranged on the bracket 1 and plays a role of outputting power, the two clamping claws 3 are oppositely arranged and can realize opening and closing of the clamping claws through the driving system, so that a pipeline 5 in a well body 4 is loosened or held tightly, the box body 6 is fixedly arranged on the bracket 1, two wall supporting structures are respectively arranged at two ends of the inside of the box body 6, and when the power tongs are hung into a construction position in the well body 4 through a chain (not shown in the figure), the two wall supporting structures in the box body 6 respectively extend out of the inside of the box body 6 and tightly support against the inner side wall of the well body 4, thereby temporarily fixing the power tongs in the well body 4, effectively preventing the power tongs from shaking due to the influence of a hanging chain, and further enabling the clamping claws of the power tongs to be quickly aligned with the pipeline 5 to be detached, so that the disassembly process of the pipeline 5 is accelerated.

Further, each wall supporting structure may include a driving motor (not shown in the figure), a telescopic structure 72 and a supporting plate 71, wherein an output shaft of the driving motor is connected with the telescopic structure 72 to drive the telescopic structure 72 to stretch out and draw back, and the supporting plate 71 is fixedly mounted at a free end of the corresponding telescopic structure 72 and abuts against an inner side wall of the well body 4 along with stretching out of the telescopic structure 72.

In order to enhance the stability of the abutting structure in the well body 4, a plurality of abutting strips 711 are uniformly distributed on one surface of the two abutting plates 71 facing the inner side wall of the well body 4, and the pressing force between the two abutting strips 711 and the well body 4 is enhanced, so that the power tongs are stably fixed in the well body 4.

As described above, as an alternative embodiment, the telescopic structure 72 may be an electric cylinder, an air cylinder or a hydraulic cylinder, or may be a diamond hinge structure, referring to fig. 2 and fig. 3, when the telescopic structure 72 is a diamond hinge structure, an output shaft of the driving motor is connected with a screw transmission in the middle of the corresponding diamond hinge structure, and the driving motor drives the screw to rotate, so that the rest of the diamond hinge structure is driven by the screw to stretch.

In order to ensure that the wall supporting structures can smoothly extend out of the box body 6, two rectangular openings communicated with the inside of the box body 6 can be formed in two end faces of the box body 6, and each wall supporting structure extends out through the corresponding opening and is tightly supported on the inner side wall of the well body 4.

In addition, the positions where the openings are arranged at the two ends of the box body 6 are also respectively provided with an opening plate 61, the top end of each opening plate 61 is hinged above the opening, and the lower part of each opening plate 61 can completely cover the corresponding opening.

When the wall supporting structure stretches out from the inside of the box body 6, the wall supporting structure jacks up the corresponding opening and closing plates 61 and stretches towards the inner side wall of the well body 4, when the pipeline 5 is disassembled and the power tongs need to be lifted back to the ground from the inside of the well body 4, the wall supporting structure is retracted to the inside of the box body 6, and the two opening and closing plates 61 cover the corresponding openings under the action of the gravity of the two opening and closing plates 61, so that the box body 6 is kept in a relatively airtight state, and the wall supporting structure inside the box body 6 is prevented from being damaged.
