Description
Technical Field
[0001] This utility model is specifically a hydraulic wrench auxiliary positioning and support device for disassembling and assembling drilling and production pipelines, which relates to the field of oil drilling and production equipment technology. Background Technology
[0002] In oil drilling and production operations, oil pipelines, mud pipes, and other drilling and production pipelines need to be connected into a transport line several kilometers long, with each pipe connected by flanges. To ensure the reliability of the connection, hydraulic wrenches are usually used to tighten the bolts or nuts used to connect the flanges. The problems with this are: hydraulic wrenches are heavy, making them inconvenient for workers to operate, and workers also have to withstand the reaction force generated by the hydraulic wrench, which can easily lead to excessive fatigue. Utility Model Content
[0003] To overcome the shortcomings of the prior art, this utility model discloses a hydraulic wrench-assisted positioning and support device for disassembling and assembling drilling pipelines, as follows:
[0004] A hydraulic wrench-assisted positioning and support device for disassembling and assembling drilling and production pipelines mainly consists of an arc track, a guide block, a sliding column, and an anti-rotation plate. The arc track is arranged along the circumference of the drilling and production pipeline, and magnetic seats are provided at both ends of the arc track to magnetically attach the arc track to the drilling and production pipeline. At least three rollers that cooperate with the arc track are provided on the guide block, allowing the guide block to move along the arc track. The sliding column cooperates with the guide block and can slide along the axial direction of the drilling and production pipeline.

[0012] The arc track, guide block, and sliding column in this hydraulic wrench's auxiliary positioning and support device play an auxiliary positioning role for the hydraulic wrench, enabling the hydraulic wrench to be easily aligned with the bolt.
[0013] The anti-rotation plate in the auxiliary positioning and support device of this hydraulic wrench can counteract the reaction force generated by the hydraulic wrench, allowing workers to operate the hydraulic wrench easily.

[0022] A hydraulic wrench-assisted positioning and support device for disassembling and assembling drilling pipelines is disclosed, relating to the field of oil drilling equipment technology. It primarily addresses the problem of excessive worker fatigue caused by operating hydraulic wrenches for disassembling and assembling drilling pipelines in existing technologies. The composition and working principle of this utility model are described in detail below.
[0023] See attached document Figure 1 and attached Figure 2 The auxiliary positioning and support device for the hydraulic wrench 9 of this utility model mainly consists of an arc track 1, a guide block 4, a sliding column 6, and an anti-rotation plate 7.
[0024] See attached document Figure 3 In this embodiment, two circular arc tracks 1 are provided, arranged circumferentially along the drilling and production pipeline 10, with the center of each track 1 coinciding with the axis of the drilling and production pipeline 10. Magnet seats are provided at both ends of the circular arc tracks 1, used to magnetically attach the tracks 1 to the drilling and production pipeline 10. An axial positioning rod 3 is connected to the magnet seat, arranged axially along the drilling and production pipeline 10. During operation, the axial positioning rod 3 rests against the flange of the drilling and production pipeline 10, serving to axially position the circular arc tracks 1.
[0025] To facilitate disassembly of the magnet base, a rotating magnet base 2 is selected. The rotating magnet base 2 is an existing product and is commonly used in dial indicator bases. The rotating magnet base 2 has a rotatable magnetic core. Rotating the magnetic core to the left weakens the magnetism of the rotating magnet base 2, while rotating the magnetic core to the right strengthens the magnetism of the rotating magnet base 2.
[0026] See attached document Figure 4At least three rollers 5 are provided on the guide block 4 to cooperate with the arc track 1, so that the guide block 4 can move along the arc track 1. In this embodiment, three rollers 5 are provided at both ends of the guide block 4 to cooperate with the arc track 1, wherein one roller 5 is located on the inner side of the arc track 1, and the other two rollers 5 are located on the outer side of the arc track 1.
[0027] The guide block 4 has a guide hole arranged along the axial direction of the drilling and production pipeline 10. The sliding pin 6 cooperates with the guide hole and can slide along the axial direction of the drilling and production pipeline 10. In order to facilitate the alignment of the bolts 11 on the flange, the distance from the sliding pin 6 to the axis of the drilling and production pipeline 10 is equal to the distance from the flange connection hole to the axis of the drilling and production pipeline 10.
[0028] An anti-rotation plate 7 is connected to the lower end of the slide column 6 in a V-shape, and a hydraulic wrench 9 is connected to the anti-rotation plate 7 by bolts 11. The anti-rotation plate 7 is used to limit the rotation angle of the slide column 6. Since the flange uses hexagonal bolts 11, the anti-rotation plate 7 limits the rotation angle of the slide column 6 to within ±30°. A handle 8 is provided at the upper end of the slide column 6, which facilitates the operation of the hydraulic wrench 9 to move up and down or rotate at small angles.
[0029] See attached document Figure 5 and attached Figure 6 During operation, the circular track 1 is magnetically attached to the drilling and production pipeline 10 by rotating the magnet base 2, and the axial positioning rod 3 is pressed against the flange of the drilling and production pipeline 10 to axially position the circular track 1. Then, the guide block 4 is moved by the handle 8 to align the nozzle of the hydraulic wrench 9 with the bolt 11. Finally, the handle 8 is pressed down, and the hydraulic wrench 9 is activated to tighten the bolt 11. After the bolt 11 is tightened, the guide block 4 or the circular track 1 is moved to tighten other bolts 11. During the tightening of the bolts 11, the anti-rotation plate 7 is supported on the drilling and production pipeline 10, which counteracts the reaction force generated by the hydraulic wrench 9, so the worker can easily operate the hydraulic wrench 9.
[0030] It is worth noting that this hydraulic wrench-assisted positioning and support device can also be used for disassembling drilling and production pipelines. Drilling and production pipelines can be connected horizontally or vertically.
[0031] In summary, the arc-shaped track, guide block, and sliding column in this hydraulic wrench's auxiliary positioning and support device assist in positioning the hydraulic wrench, allowing it to be easily aligned with the bolt. Furthermore, the anti-rotation plate counteracts the reaction force generated by the hydraulic wrench, enabling workers to operate it with ease.
[0032] It is worth noting that the content not described in detail in the above embodiments is prior art. It is also worth noting that any additions, subtractions, substitutions, and improvements made by those skilled in the art based on the structure and principles of this utility model should be included within the protection scope of this utility model.
