Description

Technical Field

[0001] This utility model relates to the technical field of chassis auxiliary support devices, and more specifically, to a self-made chassis for a well repair machine. Background Technology

[0002] Outriggers are auxiliary support devices in the workover rig chassis, usually connected to the chassis frame via hydraulic cylinders. During operation, the outriggers extend, with the end plates supporting the ground, transferring the weight of the equipment from the walking mechanism to the ground, enhancing stability; they retract when traveling and do not participate in movement.

[0003] Publication No. (CN222686106U) discloses a scaffolding footboard, comprising a footboard with a fixed support and a movable support at its bottom. The fixed support is fixedly connected to the footboard, and the movable support is movably connected to the footboard. Both the movable support and the fixed support are arranged in an L-shape. The top of the movable support is fixedly connected to the bottom of a movable block. The movable block has two opposite locations, each with a through hole for a pivot shaft to pass through. The pivot shaft is located inside the footboard. The fixed and movable supports at the bottom of the scaffolding allow a second mounting plate to be installed on them, facilitating the installation of the support plate and providing support to the footboard to prevent bending and breakage. Furthermore, the magnetic plate inside the footboard can attract and hold metal tools that fall onto it, further reducing the risk of falling objects from heights.

[0004] However, this type of scaffolding footboard has the following drawbacks: In actual use, when encountering uneven road surfaces, it is usually necessary to stack wooden planks, stakes, or other blocks for support. This operation is both dangerous and cumbersome. It is impossible to adjust the angle of the footboard according to the angle of the road surface to make the footboard fit the road surface without damaging the road surface and improving work efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a self-made chassis for a well repair machine, so as to solve the problem that the angle of the footboard cannot be adjusted according to the angle of the road surface in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a self-made chassis for a well workover rig, comprising...

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: a self-made chassis for a well workover rig, including a base plate 1 and a cylinder 2. A connecting column 4 is fixedly connected to the driving end of the cylinder 2. A ball bearing 5 is fixedly connected to the end of the connecting column 4 away from the cylinder 2. A fixed plate 8 is fixedly connected to the driving end of the cylinder 2. A bearing plate 6 is movably connected to the outside of the ball bearing 5. A plurality of movable balls 12 are movably connected to the inner wall of the bearing plate 6. A plurality of ball sleeves 9 are movably connected to the inner wall of the fixed plate 8.

[0025] By activating four cylinders 2, the base plate 1 is brought to a horizontal position with the well. During the adjustment process, the ball bearings 5 ​​move inside the bearing plate 6, allowing the bearing plate 6 to adapt to different ground angles, until the base plate 1 and the wellhead are in a horizontal and vertical position. The ball bearing sleeve 9 is the key component for achieving this adjustment.

[0026] Example 2: Based on Example 1, in order to enhance the stability of the base plate 1, a limiting sleeve 3 is fitted on the outside of the cylinder 2, multiple movable grooves 15 are opened on the inner wall of the bearing plate 6, a gasket 7 is fixedly connected to the outside of the bearing plate 6, a fixing groove 14 is opened on the inner wall of the fixing plate 8, the outside of the limiting sleeve 3 is in contact with the outside of the fixing plate 8, the outside of the connecting column 4 is in contact with the inner wall of the bearing plate 6, the outside of the cylinder 2 is fixedly connected to the inner wall of the fixing groove 14, and the outside of the connecting column 4 is in contact with the inner wall of the movable groove 15.

[0027] When the bearing plate 6 is adjusted to be in a horizontal fit with the ground, the shim 7 will first come into contact with the cement road surface, which can increase the friction with the cement road surface. This improves the overall stability and operational precision of the well repair machine in the base plate 1 when repairing the inside of the well. At the same time, the ball bearing 5 and the movable ball bearing 12 will move inside the movable groove 15 to achieve adjustment according to the specific road surface conditions.

[0028] Example 3: Based on Example 2, in order to facilitate the adjustment of the support plate 6, the external of the movable ball 12 is movably connected to the inner wall of the movable groove 15. The end of the movable ball 12 away from the support plate 6 is fixedly connected to the lead screw 10, and the end of the lead screw 10 away from the movable ball 12 is fixedly connected to the knob 11. The inner wall of the fixed plate 8 is provided with a connecting groove 13. The external of the ball 5 is movably connected to the inner wall of the movable groove 15. The external of the lead screw 10 is in contact with the inner wall of the movable groove 15. The external of the ball sleeve 9 is movably connected to the inner wall of the connecting groove 13. The end of the lead screw 10 away from the movable ball 12 is in contact with the inner wall of the connecting groove 13. The external of the fixed plate 8 is in contact with the external of the support plate 6. The external of the knob 11 is in contact with the external of the fixed plate 8.

[0029] When the ground is uneven with the wellhead, the screw 10 rotates in the ball sleeve 9 by rotating the knob 11. The ball sleeve 9 only moves inside the connecting groove 13 and does not rotate. It does not affect the tilt of the ball sleeve 9 according to the angle of the screw 10. By rotating and adjusting the four screws 10, the bearing plate 6 can be horizontally fitted according to the angle of the ground without damaging the road surface and increasing stability.

[0030] The working process of this utility model is as follows:

[0031] First, when the workover rig repairs the well, the cylinder 2 in the base plate 1 is activated, causing the bearing plate 6 to contact the ground, making the base plate 1 horizontal and perpendicular to the wellhead. At this time, the gasket 7 will contact the ground first, and the gasket 7 has the effect of increasing friction, which ensures its stability on the cement road surface. In some soils, different gaskets 7 can be replaced to suit different scenarios. When the ground is uneven with the wellhead, the knob 11 is rotated, causing the lead screw 10 to rotate in the ball sleeve 9. The ball sleeve 9 only moves inside the connecting groove 13 and does not rotate, and it does not affect the tilting of the ball sleeve 9 according to the angle of the lead screw 10. By rotating and adjusting the four lead screws 10, the bearing plate 6 can be horizontally fitted according to the angle of the ground, without damaging the road surface and increasing stability.

[0032] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
