Description

Technical Field

[0001] This utility model belongs to the technical field of power equipment maintenance, and specifically relates to a bolt loosening device for live bolt disassembly and assembly. Background Technology

[0002] In power systems, the maintenance of substation equipment is crucial. When hot-point bolts in the equipment show signs of corrosion, workers face a series of challenges during bolt removal and installation. Corrosion not only complicates the process but can also affect the normal operation of the equipment. To effectively address this problem, workers typically need to first spray a loosening agent onto the hot-point bolts to remove rust, thus ensuring smooth disassembly and installation.

[0003] However, currently, the application of loosening agents mainly relies on manual operation by workers. Considering that power equipment is usually installed at high locations and the operating space for some bolts is limited, this not only poses safety hazards for working at heights but also makes it difficult to maintain a stable spraying operation for extended periods, thus affecting the rust-removing effect of the loosening agent. Furthermore, since loosening agents have a certain degree of volatility or corrosiveness, direct manual operation may also pose a potential threat to the health of workers. Summary of the Invention

[0004] This invention aims to provide a bolt loosening tool for live bolt removal, specifically designed for bolt disassembly operations in electrical equipment. This clamp solves the problems encountered in existing bolt removal technologies, particularly when dealing with rusted bolts located at height or in confined operating space. Its goal is to improve the efficiency and success rate of bolt removal, ensuring that the loosening agent can penetrate evenly and efficiently into the gap between the bolt and the equipment, effectively breaking down rust and tightening forces. In this way, the bolt removal process is simplified, and the potential risks to workers performing high-altitude operations and inhaling loosening agents are reduced.

[0005] To achieve the above objectives, this utility model provides a bolt loosening device for live disassembly and assembly. The key features are: a clamping structure set relative to the loosening agent canister and a pressing structure set relative to the loosening agent self-spraying valve. The clamping structure includes a fixed clamping arm and a movable clamping arm, the distance between which is adjustable. A support rod connector is also provided on the fixed clamping arm.

[0006] Furthermore, the movable clamping arm is connected to the fixed clamping arm via a guide rail, and the position of the movable clamping arm on the guide rail is adjusted by a lead screw.

[0007] Furthermore, a mounting platform with a threaded hole is formed at the end of the fixed clamping arm. The head end of the lead screw is rotatably connected to the movable clamping arm, and its end extends outward through the threaded hole and is connected to an internal hexagonal sleeve for receiving rotational power.

[0008] Furthermore, the pressing structure includes a pull rod that runs vertically through the fixed clamping arm, an extension arm that is horizontally connected to the upper end of the pull rod, a pressing cap that can be adjusted in position along its length on the extension arm, and a spring that is sleeved on the pull rod between the extension arm and the fixed clamping arm.

[0009] Furthermore, a strip-shaped groove is provided along the length direction of the extension arm, and an adjusting screw is provided on the pressing cap that passes through the strip-shaped groove. A wing nut for locking the position of the pressing cap is provided on the adjusting screw.

[0010] Furthermore, a hook is provided at the lower end of the lever.

[0011] Furthermore, it also includes a support rod and a pull rope, wherein the support rod is connected to the fixed clamp arm via a support rod connector, and the pull rope is connected to the pull rod via a pull hook.

[0012] Furthermore, a handle is also connected to the lower end of the pull rope.

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] Figure 1 The first embodiment of the present invention is shown: a bolt loosening device for live disassembly and assembly, characterized in that: it includes a clamping structure 1 disposed relative to the loosening agent canister 6 and a pressing structure 2 disposed relative to the loosening agent self-spraying valve 7. The clamping structure 1 includes a fixed clamping arm 101 and a movable clamping arm 102, the distance between the two being adjustable. A support rod connector 103 is also disposed on the fixed clamping arm 101.

[0030] like Figure 2 As shown, in a specific implementation, the movable clamping arm 102 is connected to the fixed clamping arm 101 via a guide rail 104, and the position of the movable clamping arm 102 on the guide rail 104 is adjusted by a lead screw 105. A mounting platform 106 with a threaded hole 108 is formed at the end of the fixed clamping arm 101. The first end of the lead screw 105 is rotatably connected to the movable clamping arm 102, and its end extends outward through the threaded hole 108 and is connected to an internal hexagon socket 107 for receiving rotational power. The design of the internal hexagon socket 107 allows the user to rotate the lead screw 105 using a wrench or other tools, thereby achieving precise adjustment of the position of the movable clamping arm 102. Furthermore, the guide rail 104 not only ensures the stability of the movable clamping arm 102 during movement but also makes the adjustment of the clamping structure 1 smoother. When it is necessary to clamp the loosening agent canister 6, the user only needs to rotate the internal hexagon socket 107, which drives the movable clamping arm 102 to move on the guide rail 104 via the lead screw 105. After adjusting to a suitable distance, the loosening agent canister 6 can be firmly clamped between the movable clamping arm 102 and the fixed clamping arm 101. At this time, by pressing the loosening agent self-spraying valve 7 through the pressing structure 2, the loosening agent can be evenly sprayed onto the bolt, achieving rapid loosening of the bolt.

[0031] from Figure 3As can be seen, in this embodiment, the pressing structure includes a pull rod 201 that runs vertically through the fixed clamping arm 101, an extension arm 202 that is horizontally connected to the upper end of the pull rod 201, a pressing cap 203 that can be adjusted in its length direction is provided on the extension arm 202, and a spring 204 is also sleeved on the pull rod 201 between the extension arm 203 and the fixed clamping arm 101.

[0032] A slotted groove 205 is formed along the length of the extension arm 202. An adjusting screw 206 passes through the slotted groove 205 on the pressing cap 203. A wing nut 207 for locking the pressing cap 203 is mounted on the adjusting screw 206. A hook 208 is provided at the lower end of the pull rod 201. The slotted groove 205 allows the adjusting screw 206 to move within a certain range, thus enabling fine-tuning of the pressing cap 203 to accommodate bolts of different sizes or operational needs. The wing nut 207 provides a convenient locking method; users can easily fix the pressing cap 203 in place by simply rotating the nut, ensuring operational stability and accuracy.

[0033] Figure 4 and Figure 5 The illustration shows a second embodiment of the present invention, which is an improvement on the first embodiment. Specifically, the bolt loosening device for live disassembly and assembly is equipped with a support rod 3 and a pull rope 4. The support rod 3 is connected to the fixed clamp arm 101 via a support rod connector 103. The pull rope 4 is connected to the pull rod 201 via a pull hook 208, and a handle 5 is also connected to the lower end of the pull rope 4.

[0034] like Figures 6 to 8 As shown in the figure, in actual operation, the user can use the support rod 3 as a support point and pull the lever 201 via the pull rope 4 to remotely press the loosening agent self-spraying valve 7. This design not only further improves the convenience of operation but also effectively avoids physical discomfort or safety hazards that users may encounter when working at heights or in confined operating spaces. Especially when bolt disassembly work requires a long time, the auxiliary role of the support rod 3 and the pull rope 4 can significantly reduce the user's physical burden and improve work efficiency.

[0035] In summary, this utility model provides a robust and easy-to-operate bolt loosening device for live bolt removal and installation. It cleverly integrates clamping and pressing mechanisms to ensure that the loosening agent is sprayed accurately and efficiently onto the bolt surface. Especially in situations involving high-altitude operations or limited operating space, this device significantly improves work efficiency and safety. By adjusting the spacing of the clamping structure 1 and the position of the pressing structure 2, the device can accommodate loosening agent aerosol cans of various sizes, thereby enhancing its versatility and flexibility. The introduced support rod 3 and pull rope 4 further enhance stability and comfort during operation, effectively reducing the physical burden on workers and safety risks.

[0036] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model.
