DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1~Figure 4 As shown, the utility model provides a drilling pipe straightening device, including a straightening platform 1, the straightening platform 1 can realize the position fixing of the drilling pipe straightening area through anchor cables, the straightening platform 1 is rotatably connected with a rotating disk 2, and the rotating disk 2 is provided with a straightening through groove 21, the straightening through groove 21 can be used for the insertion of the drilling pipe, the rotating disk 2 is also provided with at least two pairs of shifting grooves 22, the straightening platform 1 is provided with a self-locking rotating drive structure 3 for driving the rotating disk 2 to rotate, the top and bottom of the straightening platform 1 are provided with frame structures 4, and each frame structure 4 is provided with two pairs of linear moving components 5.

[0022] A floating plate 8 is fixedly connected to the lower surface of the righting platform 1 , and the floating plate 8 can be used to increase the buoyancy of the righting platform 1 .

[0023] The self-locking rotation drive structure 3 includes a motor 31, a worm gear reducer 32 fixedly connected to the output end of the motor 31, a gear 33 fixedly connected to the output end of the worm gear reducer 32, and a winding rack 34 meshingly connected to the gear 33. The winding rack 34 is fixedly connected to a peripheral position on the upper surface of the rotating disk 2. In the present application, the winding rack 34 is a small-segment rack.

[0024] Specifically, by outputting rotational force through the motor 31, the worm gear reducer 32 can output power with self-locking, so that the gear 33 meshing with the rack 34 around the disk can make the rotating disk 2 rotate on the straightening platform 1. When the motor 31 stops outputting power, the rotating disk 2 is not easy to rotate and is relatively stable.

[0025] The frame structure 4 includes a support frame 41 and a plurality of legs 42 fixedly connected to the support frame 41 . The legs 42 are fixedly connected to the straightening platform 1 . The slide 51 is fixedly connected to the support frame 41 . The frame structure 4 provides erection and support for the linear moving component 5 .

[0026] The outer surface of the rotating disk 2 is rotatably connected to the straightening platform 1 through the bearing 9. The rotating disk 2 can stably rotate on the straightening platform 1 to provide power for straightening and fixing the drilling pipe.

[0027] The linear moving component 5 includes a slide 51 and a supporting slide 52 slidably connected to the slide 51, a movable slide column 6 is fixedly connected to the supporting slide 52, and the movable slide column 6 is slidably connected in the displacement groove 22. The supporting slide 52 passes through one end of the slide 51 and is fixedly connected with a retaining block 7 for clamping the drilling pipe. Two pairs of retaining blocks 7 are synchronously pressed against the surface wall of the drilling pipe, and the retaining blocks 7 distributed at four points can effectively straighten and fix the drilling pipe.

[0028] A linear groove for supporting the sliding of the slide plate 52 is provided on the slide seat 51. In the present application, the support slide plate 52 can slide linearly in the linear groove and is not easy to fall out. The inner width of the linear groove is larger than the diameter of the movable slide column 6. The advantage of the size design is that the movable slide column 6 can easily pass through the linear groove of the slide seat 51, so that the support slide plate 52 can be easily controlled to move along an effective path.

[0029] Specifically, the drilling pipe is sent into the straightening groove 21 by the lifting equipment for operation. When the drilling pipe needs to be straightened, the worm gear reducer 32 can provide stable rotational power for the rotating disk 2. Under the linear guide provided by the slide seat 51 for the supporting slide plate 52, the movement of the rotating disk 2 can drive the moving slide column 6 to slide through the shift groove 22, so that the supporting slide plates 52 at both ends of the moving slide column 6 can synchronously move toward the center of the straightening groove 21, so as to synchronously drive the fixing blocks 7 set at the top and bottom of the straightening platform 1 to act on the drilling pipe. In this way, the drilling pipe can be quickly fixed to achieve the straightening effect. Moreover, since the fixing blocks 7 in the two areas move synchronously, the upper and lower clamping points determine a straight line, which can improve the straightening quality of the drilling pipe and solve the technical problems that the traditional straightening method of the drilling pipe is time-consuming and labor-intensive, and there are operational risks.

[0030] It should be noted that after the retaining block 7 is clamped on the drilling pipe, since the self-locking rotation drive structure 3 is a transmission machine with a self-locking function, after the self-locking rotation drive structure 3 stops driving on the rotating disk 2, the rotating disk 2 can stably lock the clamping position of the retaining block 7 to ensure the reliability of straightening.

[0031] Each embodiment in this specification is described in a related manner, and the same or similar parts between the embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
