Description

Technical Field

[0001] This utility model relates to the field of mechanical tool technology, specifically a coupling disassembly tool for use in confined spaces. Background Technology

[0002] Coupling disassembly typically uses a puller. However, in confined spaces, the puller's claws require significant swinging, making installation inconvenient. Furthermore, pullers usually use a standard lead screw as the power transmission mechanism, generating jacking force by rotating the screw. While simple and direct, this method is inefficient, especially when large jacking forces are required, demanding considerable physical exertion from the operator and prolonging the process. Moreover, due to the physical limitations of the lead screw, it cannot provide a continuous and smooth force output, potentially leading to instability during coupling disassembly. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a coupling disassembly tool for confined spaces, which can adapt to the needs of confined space operations and has the advantages of high efficiency and ease of use.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a coupling disassembly fixture for use in confined spaces, including a base plate and a pull plate, wherein the pull plate is composed of two plates, and the two plates are provided with semi-circular holes, and the two semi-circular holes form a circular hole with a diameter smaller than that of the coupling.

[0005] The pull plate is equipped with a pull rod. One end of the pull rod is fixed to the plate that makes up the pull plate, and the other end passes through the bottom plate and extends into the bottom groove opened at the bottom of the bottom plate. The bottom groove is equipped with an adjustment mechanism for adjusting the position of the pull rod and the pull plate.

[0006] The base plate is equipped with a hydraulic jack, and the push rod of the hydraulic jack is set towards the pull plate.

[0007] In a preferred embodiment, the base plate is provided with a sliding hole, and one end of the pull rod passes through the sliding hole.

[0008] In a preferred embodiment, each plate that makes up the pull plate is provided with two pull rods. The two pull rods connected to the same plate pass through the sliding holes and are then connected and fixed to the same sliding plate.

[0009] In a preferred embodiment, an adjusting screw is provided on two sliding plates that are respectively connected to the two plates that make up the pull plate. The adjusting screw has two threaded sections with opposite directions of rotation. The two sliding plates are threaded onto the two threaded sections and are threadedly engaged with the adjusting screw.

[0010] In a preferred embodiment, one end of the adjusting screw extends beyond the base plate, and the end of the adjusting screw extending beyond the base plate is provided with a connector for engaging an electric wrench.

[0011] In a preferred embodiment, a rotating handle is also provided on one end of the adjusting screw that extends outside the base plate.

[0012] The coupling disassembly fixture for use in confined spaces provided by this utility model has the following advantages by adopting the above structure:

[0013] (1) The pull plate is composed of two plates, each plate has a semi-circular hole, and the two semi-circular holes together form a circular hole with a diameter smaller than that of the coupling. This design allows the pull plate to be adjusted according to the specific size of the coupling, thereby improving the applicability of the tooling to couplings of different specifications.

[0014] (2) Compared with traditional manual or hydraulic drive methods, this invention uses a bottom groove containing an adjustment mechanism to adjust the position of the pull rod and pull plate, and provides stable thrust through a hydraulic jack set on the bottom plate. This configuration allows users to easily control the disassembly process without excessive physical labor;

[0015] (3) Compared with traditional pullers, this device has no swinging parts, so there is no need to consider the impact of narrow space on the installation of the device. Attached Figure Description

[0020] like Figure 1-2 In the present invention, a coupling disassembly tool for use in confined spaces includes a base plate 1 and a pull plate 2. The pull plate 2 is composed of two plates, on which semi-circular holes 3 are provided. The two semi-circular holes 3 form a circular hole with a diameter smaller than that of the coupling 13.

[0021] The pull plate 2 is provided with a pull rod 4. One end of the pull rod 4 is fixed to the plate that makes up the pull plate 2, and the other end passes through the bottom plate 1 and extends into the bottom groove 6 opened at the bottom of the bottom plate 1. The bottom groove 6 is provided with an adjustment mechanism for adjusting the position of the pull rod 4 and the pull plate 2.

[0022] The base plate 1 is equipped with a hydraulic top 5, and the push rod of the hydraulic top 5 is set towards the pull plate 2.

[0023] In a preferred embodiment, the base plate 1 is provided with a sliding hole 7, and one end of the pull rod 4 passes through the sliding hole 7.

[0024] In a preferred embodiment, each plate that makes up the pull plate 2 is provided with two pull rods 4. The two pull rods 4 connected to the same plate pass through the sliding hole 7 and are then connected and fixed to the same sliding plate 8.

[0025] In a preferred embodiment, two sliding plates 8, which are respectively connected to the two plates that make up the pull plate 2, are provided with adjusting screws 9. The adjusting screws 9 are provided with two threaded sections 10 with opposite directions of rotation. The two sliding plates 8 are threadedly engaged with the adjusting screws 9 on the two threaded sections 10 respectively.

[0026] In a preferred embodiment, one end of the adjusting screw 9 extends outside the base plate 1, and the end of the adjusting screw 9 extending outside the base plate 1 is provided with a connector 11 for cooperating with an electric wrench.

[0027] In a preferred embodiment, a rotating handle 12 is also provided on one end of the adjusting screw 9 that extends outside the base plate 1.

[0028] The present invention discloses a coupling disassembly fixture for use in confined spaces, which is used when disassembling coupling 13 in confined spaces:

[0029] Rotate the adjusting screw 9 (either by using an electric wrench with connector 11 or by manually turning the rotating lever 12) to move the two plates of the pull plate 2 in opposite directions and open the semi-circular holes 3. Then, place the device on the drive shaft behind the coupling 13. Then, rotate the adjusting screw 9 in the opposite direction to bring the two plates of the pull plate 2 closer together and clamp the drive shaft. At this time, the two semi-circular holes 3 cooperate to fix the coupling 13 axially. Finally, start the hydraulic jack 5 to extend the hydraulic jack 5 push rod and push the drive shaft in the coupling 13 to disengage the drive shaft from the coupling 13.

[0030] In summary, the coupling disassembly fixture proposed in this utility model for use in confined spaces not only overcomes the limitations of existing technologies but also significantly improves operational efficiency and safety, providing a new solution for practical applications in related fields.
