[0026] like Figure 1 and Figure 2As shown, in this embodiment, the disassembly and assembly device is used to disassemble and install the spacer rod, and the disassembly and assembly device includes: an operating rod 10, a first connecting seat 20, a clamping member 30, a second connecting seat 40, a plurality of connecting rods 50 and a plurality of guide structures 60. The operating rod 10 can drive the first connecting seat 20 to be movably arranged on the operating rod 10 along the axial direction of the operating rod 10. The clamping member 30 is arranged on the first connecting seat 20. The second connecting seat 40 is arranged at the end of the operating rod 10, and the operating rod 10 and the second connecting seat 40 can rotate relative to each other. A plurality of connecting rods 50 are arranged between the first connecting seat 20 and the second connecting seat 40 along the circumferential direction of the operating rod 10, the first end of the connecting rod 50 is hingedly connected to the second connecting seat 40, and the second end of each connecting rod 50 is provided with an abutment block 51, each connecting rod 50 has a recovery position and a convex abutment position, and when the connecting rod 50 is in the convex abutment position, the abutment block 51 protrudes outward from the first connecting seat 20. A plurality of guide structures 60 are provided corresponding to a plurality of connecting rods 50, and each guide structure 60 is provided between the connecting rod 50 and the first connecting seat 20. When the first connecting seat 20 moves toward the second connecting seat 40, the first connecting seat 20 drives the connecting rod 50 to move from the recovery position to the convex abutment position through the guide structure 60.

[0027] The technical solution of this embodiment is applied, and the disassembly and assembly device is used to disassemble and assemble the spacer rod. Specifically, the operating rod 10 can drive the first connecting seat 20 to move, the clamping member 30 is arranged on the first connecting seat 20, and the second connecting seat 40 is arranged at the end of the operating rod 10. The operating rod 10 and the second connecting seat 40 can rotate relative to each other. A plurality of connecting rods 50 are arranged between the first connecting seat 20 and the second connecting seat 40 at intervals along the circumference of the operating rod 10. The first end of the connecting rod 50 is hingedly connected to the second connecting seat 40, and the second end of the connecting rod 50 is provided with an abutment block 51. The connecting rod 50 has a recovery position and an outward convex abutment position, and a plurality of guide structures 60 are arranged one-to-one corresponding to the plurality of connecting rods 50. Through the above-mentioned arrangement, the operating rod 10 can drive the first connecting seat 20 to move, and the clamping member 30 is arranged on the first connecting seat 20. At the same time, under the action of the guide structure 60, the connecting rod 50 can be moved from the recovery position to the convex abutment position. At this time, the abutment block 51 protrudes from the first connecting seat 20 and can abut with the spacer rod. In this way, the spacer rod can be clamped under the action of the clamping member 30 and the abutment block 51, and then the spacer rod can be disassembled and installed. Specifically, the abutment block 51 is stably connected to the spacer rod, and then the wear of the spacer rod can be avoided during disassembly and installation. Therefore, the technical solution of this embodiment effectively solves the problem that the spacer rod in the related art is easily worn during disassembly and assembly.

[0028] It should be noted that this design enables operators to quickly position and disassemble the spacer bars through simple operations, especially in the maintenance and inspection of power lines, which can significantly improve work efficiency, reduce high-altitude working time, and increase work safety.

[0029] In practical applications, the disassembly and assembly device can greatly reduce the work intensity of power maintenance workers, especially when handling the spacer bars of high-voltage lines, its efficiency and safety are particularly prominent. For example, in high-voltage line maintenance operations in mountainous areas, due to the complex terrain, traditional manual disassembly and assembly is not only time-consuming and labor-intensive, but also poses safety risks in high-altitude operations. With the disassembly and assembly device of this embodiment, the operator can stand on the ground or on a stable work platform, and control the movement of the first connecting seat 20 and the connecting rod 50 through the operating rod 10, thereby achieving precise disassembly and assembly of the spacer bars, greatly improving the safety and efficiency of the operation.

[0030] like Figures 1 to 4 As shown, in this embodiment, the guide structure 60 includes a strip hole 61 and a positioning column 62, the positioning column 62 is movably arranged in the strip hole 61, one of the strip hole 61 and the positioning column 62 is arranged on the first connection seat 20, and the other of the strip hole 61 and the positioning column 62 is arranged on the connecting rod 50. Through the cooperation of the strip hole 61 and the positioning column 62, not only the stability of the movement of the connecting rod 50 is ensured, but also the moving trajectory of the connecting rod 50 can be accurately controlled, so that the abutment block 51 can be accurately aligned with the spacer rod, which is suitable for operations in various complex environments, such as power line maintenance in mountainous areas, forests, etc.

[0031] In the maintenance of power lines in complex terrains, such as forests and mountainous areas, due to environmental restrictions, it is often difficult for traditional tools to accurately align the spacer bars for disassembly and assembly. The disassembly and assembly device of this embodiment effectively solves this problem through the guide structure 60 of the bar hole 61 and the positioning column 62. The operator only needs to gently turn the operating rod 10, and the sliding of the positioning column 62 in the bar hole 61 will guide the connecting rod 50 to accurately align with the spacer bar. Even in an environment with poor visibility blocked by trees and rocks, the spacer bar can be disassembled and installed quickly and accurately, greatly improving the flexibility and stability of the operation.

[0032] like Figures 1 to 3 As shown, in this embodiment, the cross-sectional area of ​​the abutment block 51 gradually decreases in the direction from the first connection seat 20 to the second connection seat 40. The above makes it easier for the abutment block 51 to be inserted into the mounting hole of the spacer when it moves to the recovery position, reducing the difficulty of operation, especially when working in a narrow space, this design advantage is more obvious, such as maintenance in a dense power equipment room.

[0033] In the narrow space between power equipment, the disassembly and assembly of the spacer bars is often limited by space, and traditional tools are difficult to use, which can easily lead to operational errors. The disassembly and assembly device of this embodiment uses a gradual change design of the cross-sectional area of ​​the abutment block 51, so that the abutment block 51 can enter the installation hole more smoothly, effectively avoiding positioning difficulties and operational errors caused by narrow space. In equipment-intensive places such as substations and distribution rooms, this design can significantly improve the efficiency of disassembly and assembly of the spacer bars, providing a strong guarantee for the maintenance of power facilities.

[0034] like Figures 1 to 3 As shown, in this embodiment, the side of the abutting block 51 facing the first connecting seat 20 has a first plane 511, and the side of the abutting block 51 away from the operating rod 10 has a second plane 512. The design of the first plane 511 and the second plane 512 enables the abutting block 51 to provide a larger contact area when abutting the spacer bar, thereby increasing the stability during the disassembly and assembly process, reducing operational errors, and is suitable for scenes requiring high-precision operations, such as in the precision adjustment of power lines.

[0035] In the precision adjustment of power lines, such as when correcting minor deviations of the lines, the precision of the assembly and disassembly of the spacer bars is extremely high. The assembly and disassembly device of this embodiment provides a larger contact area through the design of the two side planes of the abutment block 51, so that during the assembly and disassembly process, the friction between the abutment block 51 and the spacer bars is increased, the stability of the operation is improved, and the inaccurate positioning and operational errors caused by tool sliding are reduced. In the maintenance of power lines that require high-precision adjustment, this design can significantly improve the accuracy and efficiency of the operation, and provide a guarantee for the safe and stable operation of the power lines.

[0036] like Figures 1 to 4 As shown, in this embodiment, the first connection seat 20 includes a connection body 21 and an extension portion 22, the extension portion 22 is connected to the connection body 21 and extends toward the second connection seat 40, and the connection rod 50 is connected between the extension portion 22 and the second connection seat 40. The design of the extension portion 22 increases the flexibility of the disassembly and assembly device, so that the operator can conveniently operate at different angles and positions, and is suitable for high-altitude operations at various angles, such as disassembly and assembly of spacer bars at different heights of a power tower.

[0037] During the aerial work on the power tower, the operator needs to disassemble and assemble the spacer rods at different angles and heights, which places high demands on the flexibility of the tool. The disassembly and assembly device of this embodiment not only increases the flexibility of the device by designing the extension part 22, but also can adapt to the operation requirements of various angles and positions. When the operator is working at different heights of the tower, he only needs to adjust the angle of the operating rod 10, and the extension part can guide the connecting rod to accurately align with the spacer rod, which greatly improves the efficiency and safety of the aerial work and provides a more convenient and reliable tool for the maintenance of power lines.

[0038] like Figures 1 to 4 As shown, in this embodiment, the cross section of the connecting body 21 is cylindrical, the cross section of the extending portion 22 is truncated cone, and the cross section area of ​​the extending portion 22 gradually increases from the connecting body 21 to the extending portion 22. The above design not only improves the structural stability of the disassembly and assembly device, but also makes the device more convenient to operate, reduces the physical exertion of the operator, and is suitable for long-term operations, such as comprehensive maintenance of power lines.

[0039] In the comprehensive overhaul of power lines, operators often need to disassemble and assemble the spacer bars for a long time, which poses a challenge to the comfort and efficiency of the tool. The disassembly and assembly device of this embodiment is designed with a cylindrical connecting body 21 and a truncated cone-shaped extension 22, which not only ensures the stability of the structure, but also makes it easier for operators to use and reduces physical exertion. In the high-intensity working environment of comprehensive overhaul, this design can effectively relieve the fatigue of operators, improve the ability of continuous operation, and provide strong support for the comprehensive maintenance of power lines.

[0040] like Figures 1 to 4 As shown, in this embodiment, the extension portion 22 includes a first extension plate 221 and a second extension plate 222, and the connecting rod 50 includes a first rod body 52 and a second rod body 53. The first extension plate 221 is arranged correspondingly to the first rod body 52, and the second extension plate 222 is arranged correspondingly to the second rod body 53. The above-mentioned segmented design makes the movement of the connecting rod 50 smoother, and also facilitates the maintenance and replacement of the device, and is suitable for environments that require frequent operations, such as in the daily maintenance of power facilities.

[0041] In the daily maintenance of power facilities, the disassembly and assembly of the spacer rods needs to be performed frequently, which requires the disassembly and assembly device to be not only smooth in operation but also easy to maintain and replace. The disassembly and assembly device of this embodiment makes the movement of the connecting rod 50 smoother through the segmented design of the extension part 22, and the operator can easily complete the disassembly and assembly of the spacer rod, reducing the jamming and delays during the operation. At the same time, the segmented extension part 22 design also facilitates the regular inspection and replacement of the connecting rod 50, ensuring the long-term stability and reliability of the tool, and providing convenience and protection for the daily maintenance of power facilities.

[0042] like Figures 1 to 4 As shown, in this embodiment, the interior of the connecting body 21 is a hollow structure, a threaded hole is provided on the end of the connecting body 21, and the operating rod 10 is a threaded rod, which is inserted into the threaded hole and rotatably connected to the second connecting seat 40. The threaded connection design of the threaded rod and the threaded hole not only ensures the stability of the disassembly and assembly device, but also makes the driving of the operating rod 10 more labor-saving, and is suitable for operations requiring a large torque, such as disassembling and assembling a relatively tight spacer in a power line.

[0043] In power lines, when encountering a tight spacer bar, traditional tools often require a large torque to complete the disassembly and assembly, which places high demands on the operator's physical strength and skills. The disassembly and assembly device of this embodiment not only enhances the stability of the disassembly and assembly device through the design of threaded connection, but also makes the driving of the operating rod 10 more labor-saving. Even when facing a tight spacer bar, the operator can easily complete the disassembly and assembly operation. In the maintenance of high-voltage lines, this design is particularly important, as it can effectively reduce the operator's physical exertion and improve the safety and efficiency of the operation.

[0044] like Figures 1 to 4 As shown, in this embodiment, the clamping member 30 includes an outer convex abutment portion 31 and an adjusting member 32. The first connecting seat 20 is provided with a plurality of limiting holes 23 extending along the axial direction thereof, and the adjusting member 32 can be plugged and matched with different limiting holes 23. This adjustable clamping member 30 design enables the disassembly and assembly device to adapt to spacers of different sizes, improves the versatility of the disassembly and assembly device, and is suitable for the disassembly and assembly of spacers of various types in power lines.

[0045] In power lines, there are various types and sizes of spacers. Traditional tools often require a variety of clamps for different types of spacers, which causes inconvenience in carrying and using the tools. The disassembly and assembly device of this embodiment realizes the adaptation to spacers of different sizes through the design of adjustable clamps 30, greatly improving the versatility of the tool. When performing a comprehensive inspection of power lines, this design allows operators to complete the disassembly and assembly of various types of spacers by simply adjusting the adjustment member 32 and the limit hole 23 without carrying a variety of tools, which significantly improves the convenience and efficiency of the operation and reduces the interruption of the operation and time waste caused by tool replacement.

[0046] like Figure 1 , Figure 2 as well as Figure 4 As shown, in this embodiment, the disassembly and assembly device further includes an operating handle 70, which is detachably disposed at the end of the operating rod 10 away from the second connecting seat 40. The detachable operating handle 70 is not only easy to carry and store, but also can adjust the length and shape of the handle according to the working environment and personal habits, thereby improving the comfort and convenience of operation, and is suitable for various working environments, such as working in a narrow space of a power facility or in an open field.

[0047] In the maintenance and overhaul of electric power facilities, the working environment is diverse, and traditional tools are often difficult to adapt to various operating conditions. The disassembly and assembly device of this embodiment is designed with a detachable operating handle 70, which is not only convenient for carrying and storing tools, but also can adjust the length and shape of the operating handle 70 according to the specific working environment and personal habits, so that the operator can comfortably perform the disassembly and assembly of the spacer rods in a narrow space or in the open field. This design is particularly suitable for maintenance in equipment-intensive places such as substations and distribution rooms, as well as line maintenance in open fields such as mountainous areas and forests. It can effectively improve the work efficiency and work safety of operators, and provide an efficient and convenient solution for the comprehensive maintenance and overhaul of the power industry.

[0048] Specifically, the disassembly and assembly device of this embodiment drives the first connecting seat 20 to move through the operating rod 10, and uses the guide structure 60 to drive the connecting rod 50 to move from the recovery position to the convex abutment position, thereby realizing efficient disassembly and assembly of the spacer rod. This design not only improves the convenience and safety of disassembly and assembly, but also reduces the physical exertion of operators, effectively improves work efficiency, and is particularly suitable for high-altitude working environments, providing powerful tool support for the maintenance of power lines. In addition, the structural design of the disassembly and assembly device fully considers the flexibility and versatility of operation, and can adapt to spacer rods of various sizes and different working environments, greatly improving the construction efficiency and safety of the power industry, and is an indispensable and efficient tool in power maintenance and repair work. By using this device, power companies can save a lot of manpower and time costs, while ensuring the normal operation of power facilities, and providing society with a more stable and reliable power supply.

[0049] In practical applications, especially in the high-altitude maintenance and overhaul operations of power lines, such as the disassembly and assembly of spacer bars of high-voltage transmission towers, the disassembly and assembly device of this embodiment has demonstrated its unique advantages. It is not only convenient to operate, safe and reliable, but also can adapt to spacer bars of various sizes and is suitable for different working environments. The operator only needs to drive the first connecting seat 20 through the operating rod 10, and can use the guide structure 60 to accurately control the movement of the connecting rod 50, accurately align the abutment block 51 with the spacer bar, and achieve efficient disassembly and assembly. This design effectively reduces the time of high-altitude operations, reduces operational risks, and greatly improves the efficiency of power maintenance work. In the context of comprehensive construction in the power industry, the use of this efficient tool not only saves a lot of manpower and time costs for power companies, but also ensures the normal operation of power facilities, and provides the society with a more stable and reliable power supply. It is an indispensable tool in power maintenance and overhaul operations.
