Detailed Description

In order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and techniques are omitted so as to not unnecessarily limit the invention.

As shown in fig. 1-5, a hydraulic tong moving device comprises a workover power tong (specially designed as XQ114/6B in the prior art, and also described in patent 201820448529.3 filed by the same company), a tong clamping driving base mechanism and a guiding mechanism; the workover power tong is arranged at the power output end of the pipe wrench clamping driving base mechanism and comprises an upper rotary clamping tong 701 and a lower fixed clamping tong 702; the guiding mechanism is mounted between the rotating clamp 701 and the fixed clamp 702 and is coaxially arranged. In the process of loading and unloading the pipe rod, the pipe wrench clamping driving base mechanism is used for driving the well repairing power wrench and the guiding mechanism to be close to or far away from the pipe rod. The pipe wrench clamping driving base mechanism comprises a folding frame 703, a frame body advancing and retreating driving oil cylinder 704 and a frame body height adjusting oil cylinder 705. The lower end of the folding leg 703 is provided with a slider which is mounted on a guide rail on the vehicle device 1 so as to be slidable inward and outward. The frame body advancing/retreating driving cylinder 704 is disposed longitudinally, the rear end thereof is connected to the vehicle device 1, and the front end thereof is connected to the lower portion of the folding leg 703. The frame body height adjusting oil cylinder 705 is vertically and obliquely arranged, the lower end of the frame body height adjusting oil cylinder is hinged with the lower end of the folding frame 703 through a support, and the upper end of the frame body height adjusting oil cylinder is hinged with the upper end of the folding frame 703 through a support. The frame body advancing and retreating driving oil cylinder 704 is matched with the frame body height adjusting oil cylinder 705 to realize the outward extending type ascending or the inward retracting type descending of the hydraulic pipe wrench device 7. In the process of installing the pipe rod, the guide mechanism is used for guiding the pipe rod so as to facilitate the alignment of the upper pipe rod and the lower pipe rod; the pipe rod dismounting device is used for preventing liquid of the lower pipe rod from splashing outwards in the pipe rod dismounting process; the guide mechanism includes a guide support plate 706, a guide drive cylinder 707, a guide cylinder 708, and a guide block 709. The guide support plates 706 are vertically installed at both sides of the fixed clamp 702, and guide driving cavities are transversely arranged on the guide support plates 706. The guide cylinders 708 on the two sides are mounted on a guide support plate 706 through guide slide bars (the guide slide bars can be sleeved on a guide driving cavity in an inner-outer sliding mode), the guide driving oil cylinders 707 on the two sides are mounted on the outer side of the guide support plate 706, and the telescopic power output ends of the guide driving oil cylinders 707 are connected with the guide cylinders 708. The guide blocks 709 are symmetrically arranged on the inner side of the guide cylinder 708, and the upper ends of the guide blocks are of conical cavity structures. An oil pipe clamping block 714 for clamping an oil pipe is arranged on the inner sides of the jaws of the upper rotary clamping forceps 701 and the lower fixed clamping forceps 702. When the oil pipe is installed, the upper oil pipe passes through the guide mechanism, and the lower end of the upper oil pipe is inserted into the upper end coupling of the lower oil pipe; the lower fixed clamp 702 clamps and fixes the lower oil pipe, and the upper rotary clamp 701 drives the upper oil pipe to rotate. When the oil pipe is disassembled, the process is similar to the above process and is not repeated.

In addition to the technical features described in the specification, the technology is known to those skilled in the art.
