Technical Field

[0001] This utility model relates to the field of pipeline construction technology, specifically to a special tool for pipeline jacking, leveling, and centering. Background Technology

[0002] Industrial pipelines are used for the recycling of liquids such as cooling oil and lubricating oil, improving production efficiency and energy utilization. In the production of precision electronic components, industrial pipelines provide a pure supply of gases and liquids, requiring high sealing and filtration performance. These types of pipelines have become an indispensable part of modern industry due to their unique performance and wide range of applications.

[0003] Pipe prefabrication, welding, and leveling of pipe flange interfaces are all crucial aspects of the construction process. The lack of appropriate tools for centerline alignment of pipes significantly impacts work efficiency and creates considerable difficulties. Utility Model Content

[0004] The purpose of this invention is to provide a special tool for jacking, leveling, and centering pipelines to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A special tool for jacking, leveling, and centering pipelines includes a hydraulic jack. The hydraulic jack includes a telescopic column mounted at its output end, the telescopic column having a rectangular cross-section. It also includes a base, the upper surface of which is slidably provided with a support portion and clamping portions symmetrically arranged relative to the support portion. Wherein:

[0007] The clamping part slides horizontally, and the supporting part slides vertically;

[0008] The base is provided with a traction member welded to the bottom of the support part. The traction member is pushed by a retaining spring provided in the base to maintain the default height. The traction member is movably connected to the two clamping parts by a pull rod.

[0009] The base is connected to the screw rod threaded to the end face of the telescopic column.

[0010] Preferably, a bracket is fixedly installed at the end of the telescopic column, and limiting rods that are slidably connected to the bracket are symmetrically arranged on the base;

[0011] The base and the screw are rotatably connected.

[0012] Preferably, each of the two clamping portions has a groove on its adjacent surface, and an arc-shaped elastic metal plate is provided in the groove, the arc-shaped elastic metal plate protruding toward the support portion.

[0013] Preferably, the outer surface of the arc-shaped elastic metal plate is provided with a hard rubber coating.

[0014] Preferably, the bracket is rotatably provided with a threaded ring that is threaded to the screw on the side facing the telescopic column.

[0015] Preferably, the bracket is rotatably provided with a rotating part sleeved on the outside of the threaded ring, and the side wall of the rotating part is provided with symmetrically arranged insertion tubes;

[0018] In the above technical solution, the special tool for pipe jacking, leveling and centering provided by this utility model has the following beneficial effects: the telescopic column is driven to extend by a hydraulic jack, so that the support part contacts the pipe. As the hydraulic jack continues to extend, the support part moves down, thereby pulling the two clamping parts to move towards each other, thereby clamping the pipe. Then, the pipe is lifted by a hydraulic jack to keep it horizontal. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, a special tool for jacking, leveling, and centering pipelines includes a hydraulic jack 1. The hydraulic jack 1 includes a telescopic column mounted at its output end, the telescopic column having a rectangular cross-section. The tool is characterized by further including a base 2. The upper surface of the base 2 is slidably provided with a support portion 3 and clamping portions 4 symmetrically arranged opposite the support portion 3. Wherein:

[0028] The clamping part 4 slides horizontally, and the supporting part 3 slides vertically;

[0029] The base 2 is provided with a traction member 31 welded to the bottom of the support part 3. The traction member 31 is pushed by the retaining spring 5 provided in the base 2 to maintain the default height. The traction member 31 is movably connected to the two clamping parts 4 by the pull rod 41 respectively.

[0030] The base 2 is connected to the screw 6, which is threaded to the end face of the telescopic column.

[0031] Specifically, the hydraulic jack 1 in the embodiment is prior art. In the embodiment, when the support part 3 is pressed down, the spring 5 is deformed. At this time, the pulling member 31 pulls the pull rod 41, causing the two clamping parts 4 to move towards each other.

[0032] In the above technology, the telescopic column is extended by the hydraulic jack 1, so that the support part 3 contacts the pipeline. As the hydraulic jack 1 continues to extend, the support part 3 moves down, thereby pulling the two clamping parts 4 to move towards each other, thus clamping the pipeline. Then, the hydraulic jack 1 is used to lift the pipeline to keep it horizontal.

[0033] As a further embodiment of this utility model, a bracket 11 is fixedly installed at the end of the telescopic column, and a limiting rod 21 that is symmetrically arranged on the base 2 and slidably connected to the bracket 11 is provided. The base 2 and the screw 6 are rotatably connected.

[0034] Specifically, the base 2 is slidably connected to the bracket 11 by two limit rods 21, so that the base 2 moves up and down with the screw 6 without selection.

[0035] As a further embodiment of this utility model, the two clamping parts 4 are provided with grooves on adjacent surfaces, and an arc-shaped elastic metal plate 42 is provided in the groove. The arc-shaped elastic metal plate 42 protrudes toward the support part 3, and a hard rubber outer cover is provided on the outer side of the arc-shaped elastic metal plate 42.

[0036] Specifically, in this embodiment, the supporting part 3 moves downward, thereby pulling the two clamping parts 4 towards each other. As the two clamping parts 4 approach each other, the arc-shaped elastic metal plate 42 contacts the pipe at its apex. As the clamping distance decreases, the arc-shaped elastic metal plate 42 adapts to the pipe, thereby firmly clamping the pipe.

[0037] As another embodiment of the present invention, the bracket 11 is rotatably provided with a threaded ring 7 that is threadedly assembled with the screw 6 on the side facing the telescopic column.

[0038] Specifically, by driving the threaded ring 7 to rotate, the screw 6 rotates, thereby engaging with the support 11 to move up and down.

[0039] As another embodiment of the present invention, a rotating part 8 is rotatably provided on the bracket 11 and sleeved on the outside of the threaded ring 7, and the side wall of the rotating part 8 is provided with symmetrically arranged insertion tubes 81.

[0040] The rotating part 8 has a hollow structure, and a retaining tooth 82 is rotatably installed inside it, which engages with the toothed opening on the outer wall of the threaded ring 7.

[0041] Furthermore, a plug-in abutment 83 located inside the insert tube 81 is fixedly provided on the toothed part 81.

[0042] Specifically, in this embodiment, when the steel pipe is inserted into the plug-in abutment 83, to Figure 4 As shown, when the steel pipe faces Figure 4 Turning to the right (clockwise) will cause the locking tooth 81 to lock into the toothed edge of the outer wall of the threaded ring 7, thereby causing the rotating part 8 to drive the threaded ring 7 to rotate.

[0043] And when the steel pipe faces Figure 4 On the left (counterclockwise), the deca tooth 81 will move away from the toothed edge of the outer wall of the threaded ring 7, and the rotating part 8 will no longer drive the threaded ring 7 to rotate.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
