Description

Technical Field

[0001] This invention relates to the field of spacer assembly and disassembly technology, and more specifically, to an assembly and disassembly device. Background Technology

[0002] Spacer bars are used in power lines. They span the conductors to maintain a uniform spacing between the individual conductors of a split conductor, ensuring phase-to-phase insulation between the conductors, preventing discharge between conductors, and improving the operational safety of the power line. The installation and removal of spacer bars are generally done manually. Force is applied to both ends of the spacer to the left and right to loosen it, and then it is removed from the conductor.

[0003] Power lines have high conductors, requiring workers to climb poles to install and remove spacer bars. This labor-intensive and time-consuming work disrupts the normal operation of the power lines. Current disassembly tools consist of an operating screw and a contact block, threaded together. The contact block abuts against the spacer bar, and during disassembly, friction can occur between the contact block and the spacer bar, potentially causing damage. Summary of the Invention

[0004] The main objective of this invention is to provide a disassembly and assembly device to solve the problem of easy wear and tear on spacers during disassembly and assembly in related technologies.

[0005] To achieve the above objectives, the present invention provides a disassembly and assembly device for disassembling and installing spacers. The disassembly and assembly device includes: an operating lever; a first connecting seat, wherein the operating lever drives the first connecting seat to be movably mounted on the operating lever along the axial direction of the operating lever; a clamping member, mounted on the first connecting seat; a second connecting seat, mounted at the end of the operating lever, wherein the operating lever and the second connecting seat are rotatable relative to each other; a plurality of connecting rods, wherein the plurality of connecting rods are spaced apart circumferentially between the first and second connecting seats, wherein the first end of the connecting rod is hinged to the second connecting seat, and the second end of each connecting rod is provided with an abutment block; each connecting rod has a retracted position and an outwardly protruding abutment position, wherein when the connecting rod is in the outwardly protruding abutment position, the abutment block protrudes outward from the first connecting seat; and a plurality of guide structures, each corresponding to one of the plurality of connecting rods, wherein each guide structure is disposed between the connecting rod and the first connecting seat; wherein, when the first connecting seat moves toward the second connecting seat, the first connecting seat drives the connecting rod to move from the retracted position to the outwardly protruding abutment position through the guide structures.

[0006] Furthermore, the guide structure includes a strip hole and a positioning post, the positioning post being movably disposed within the strip hole, one of the strip hole and the positioning post being disposed on the first connecting seat, and the other of the strip hole and the positioning post being disposed on the connecting rod.

[0007] Furthermore, in the direction from the first connecting seat to the second connecting seat, the cross-sectional area of ​​the abutment block gradually decreases.

[0008] Furthermore, the abutment block has a first plane on the side facing the first connecting seat, and a second plane on the side away from the operating lever.

[0009] Furthermore, the first connecting seat includes a connecting body and an extension, the extension being connected to the connecting body and extending toward the second connecting seat, and a connecting rod being connected between the extension and the second connecting seat.

[0010] Furthermore, the cross-section of the connecting body is cylindrical, and the cross-section of the extension is frustum-shaped. From the connecting body to the extension, the cross-sectional area of ​​the extension gradually increases.

[0011] Furthermore, the extension includes a first extension plate and a second extension plate, and the connecting rod includes a first rod body and a second rod body. The first extension plate is correspondingly arranged with the first rod body, and the second extension plate is correspondingly arranged with the second rod body.

[0012] Furthermore, the interior of the connecting body is a hollow structure, and a threaded hole is provided at the end of the connecting body. The operating rod is a threaded rod, which passes through the threaded hole and is rotatably connected to the second connecting seat.

[0013] Furthermore, the clamping member includes an outwardly protruding abutment portion and an adjusting member. The first connecting seat is provided with a plurality of limiting holes extending along its axial direction, and the adjusting member can be inserted and engaged with different limiting holes.

[0014] Furthermore, the disassembly and assembly device also includes an operating handle, which is detachably disposed at the end of the operating lever away from the second connecting seat.

[0015] Applying the technical solution of this invention, the disassembly and assembly device is used to disassemble and assemble spacer bars. Specifically, the operating rod can drive the first connecting seat to move, the clamping member is disposed on the first connecting seat, and the second connecting seat is disposed at the end of the operating rod. The operating rod and the second connecting seat can rotate relative to each other. Multiple connecting rods are spaced apart along the circumference of the operating rod between the first and second connecting seats. The first end of the connecting rod is hinged to the second connecting seat, and the second end of the connecting rod is provided with an abutment block. The connecting rod has a retracted position and an outward abutment position. Multiple guide structures are provided one-to-one with the multiple connecting rods. Through the above configuration, the operating rod can drive the first connecting seat to move, the clamping member is disposed on the first connecting seat, and under the action of the guide structure, the connecting rod can move from the retracted position to the outward abutment position. At this time, the abutment block protrudes from the first connecting seat and can abut against the spacer bar. Thus, under the action of the clamping member and the abutment block, the spacer bar can be clamped, thereby realizing the disassembly and installation of the spacer bar. Specifically, the abutment block is stably connected to the spacer bar, thereby avoiding wear on the spacer bar during disassembly and installation. Therefore, the technical solution of this application effectively solves the problem of wear and tear on spacers during disassembly and assembly in related technologies. Attached Figure Description

[0026] like Figure 1 and Figure 2As shown, in this embodiment, the disassembly and assembly device is used to disassemble and install the spacer bar. The disassembly and assembly device includes: an operating lever 10, a first connecting seat 20, a clamping member 30, a second connecting seat 40, multiple connecting rods 50, and multiple guide structures 60. The operating lever 10 can drive the first connecting seat 20 to be movably mounted on the operating lever 10 along the axial direction of the operating lever 10. The clamping member 30 is mounted on the first connecting seat 20. The second connecting seat 40 is mounted at the end of the operating lever 10, and the operating lever 10 and the second connecting seat 40 can rotate relative to each other. Multiple connecting rods 50 are spaced apart circumferentially between the first connecting seat 20 and the second connecting seat 40 along the operating lever 10. The first end of the connecting rod 50 is hinged 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 retracted position and an outwardly protruding abutment position. When the connecting rod 50 is in the outwardly protruding abutment position, the abutment block 51 protrudes outward from the first connecting seat 20. Multiple guide structures 60 are provided in a one-to-one correspondence with multiple connecting rods 50, and each guide structure 60 is disposed between the connecting rod 50 and the first connecting seat 20. When the first connecting seat 20 moves to the second connecting seat 40, the first connecting seat 20 drives the connecting rod 50 to move from the retracted position to the outward protruding abutment position through the guide structure 60.

[0027] Using the technical solution of this embodiment, the disassembly and assembly device is used to disassemble and assemble the spacer bar. Specifically, the operating rod 10 can drive the first connecting seat 20 to move, the clamping member 30 is disposed on the first connecting seat 20, the second connecting seat 40 is disposed 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 disposed at intervals between the first connecting seat 20 and the second connecting seat 40 along the circumference of the operating rod 10, the first end of the connecting rod 50 is hinged to the second connecting seat 40, the second end of the connecting rod 50 is provided with an abutment block 51, the connecting rod 50 has a retracted position and an outwardly protruding abutment position, and a plurality of guide structures 60 are disposed one-to-one with a plurality of connecting rods 50. With the above configuration, the operating lever 10 can drive the first connecting seat 20 to move. The clamping member 30 is disposed on the first connecting seat 20. Simultaneously, under the action of the guide structure 60, the connecting rod 50 can move from the retracted position to the outward protruding abutment position. At this time, the abutment block 51 protrudes from the first connecting seat 20 and can abut against the spacer. Thus, under the action of the clamping member 30 and the abutment block 51, the spacer can be clamped, thereby realizing the disassembly and installation of the spacer. Specifically, the abutment block 51 is stably connected to the spacer, thereby avoiding wear on the spacer during disassembly and installation. Therefore, the technical solution of this embodiment effectively solves the problem of easy wear on the spacer during disassembly and installation in related technologies.

[0028] It should be noted that this design allows operators to quickly position and disassemble the spacers through simple operations. Especially in the maintenance and repair of power lines, it can significantly improve work efficiency, reduce the time spent working at height, and increase work safety.

[0029] In practical applications, the disassembly and assembly device can greatly reduce the workload of power maintenance workers, especially when handling spacer bars on high-voltage lines, where its efficiency and safety are particularly outstanding. For example, in high-voltage line maintenance work 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 associated with working at heights. Using the disassembly and assembly device of this embodiment, operators can stand on the ground or a stable working platform and control the movement of the first connecting seat 20 and the connecting rod 50 through the operating lever 10, thereby achieving precise disassembly and assembly of 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-shaped hole 61 and a positioning post 62. The positioning post 62 is movably disposed within the strip-shaped hole 61. One of the strip-shaped hole 61 and the positioning post 62 is disposed on the first connecting seat 20, and the other of the strip-shaped hole 61 and the positioning post 62 is disposed on the connecting rod 50. Through the cooperation of the strip-shaped hole 61 and the positioning post 62, not only is the stability of the movement of the connecting rod 50 guaranteed, but the movement trajectory of the connecting rod 50 can also be precisely controlled, so that the abutment block 51 can be accurately aligned with the spacer bar. This is suitable for operations in various complex environments, such as power line maintenance in mountainous areas and forests.

[0031] In power line maintenance in complex terrains, such as forests and mountainous areas, traditional tools often struggle to accurately align and install spacers due to environmental limitations. The installation / removal device in this embodiment effectively solves this problem through the guide structure 60 of the slotted hole 61 and the positioning post 62. The operator simply needs to gently rotate the operating rod 10; the sliding of the positioning post 62 within the slotted hole 61 guides the connecting rod 50 to accurately align with the spacer. Even in environments with poor visibility due to trees or rocks, the disassembly and installation of spacers can be completed 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 connecting seat 20 to the second connecting seat 40. This design makes it easier for the abutment block 51 to be inserted into the mounting hole of the spacer bar when it is moved to the retraction position, reducing the difficulty of operation. This design advantage is particularly evident when working in confined spaces, such as during maintenance in densely packed electrical equipment rooms.

[0033] In the confined spaces between electrical equipment, the installation and removal of spacers are often limited by space constraints, making it difficult to use traditional tools and prone to operational errors. The installation and removal device in this embodiment utilizes a gradually changing cross-sectional area design for the abutment block 51, allowing it to enter the mounting hole more smoothly and effectively avoiding positioning difficulties and operational errors caused by confined space. In densely populated locations such as substations and distribution rooms, this design significantly improves the efficiency of spacer installation and removal, providing strong support for the maintenance of power facilities.

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

[0035] In precision adjustment work on power lines, such as correcting minute deviations in the line, the installation and removal of spacers requires extremely high precision. The installation and removal device in this embodiment, through the design of the two flat surfaces of the abutment block 51, provides a larger contact area. This increases the friction between the abutment block 51 and the spacer during installation and removal, improving operational stability and reducing inaccurate positioning and operational errors caused by tool slippage. In power line maintenance requiring high-precision adjustments, this design significantly improves the accuracy and efficiency of the work, ensuring the safe and stable operation of the power lines.

[0036] like Figures 1 to 4 As shown, in this embodiment, the first connecting seat 20 includes a connecting body 21 and an extension 22. The extension 22 is connected to the connecting body 21 and extends towards the second connecting seat 40. The connecting rod 50 is connected between the extension 22 and the second connecting seat 40. The design of the extension 22 increases the flexibility of the disassembly and assembly device, allowing operators to easily operate from different angles and positions. It is suitable for high-altitude operations at various angles, such as disassembling and assembling spacers at different heights on power towers.

[0037] In high-altitude operations on power towers, operators need to install and remove spacers at different angles and heights, which places high demands on the flexibility of the tools. The installation and removal device in this embodiment, through the design of the extension section 22, not only increases the flexibility of the device but also adapts to the operational needs of various angles and positions. When operating at different heights on the tower, operators only need to adjust the angle of the operating rod 10, and the extension section can guide the connecting rod to accurately align with the spacer, greatly improving the efficiency and safety of high-altitude operations and providing a more convenient and reliable tool for power line maintenance.

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

[0039] During comprehensive maintenance of power lines, operators often need to perform long periods of disassembly and assembly of spacers, which poses challenges to the comfort and efficiency of the tools. The disassembly and assembly device in this embodiment, with its cylindrical connecting body 21 and frustum-shaped extension 22, not only ensures structural stability but also makes it easier for operators to use, reducing physical exertion. In the high-intensity working environment of comprehensive maintenance, this design effectively alleviates operator fatigue, improves the ability to work continuously, and provides strong support for the comprehensive maintenance of power lines.

[0040] like Figures 1 to 4 As shown, in this embodiment, the extension 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 correspondingly arranged with the first rod body 52, and the second extension plate 222 is correspondingly arranged with 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. It is suitable for environments that require frequent operation, such as in the daily maintenance of power facilities.

[0041] In the routine maintenance of power facilities, the disassembly and assembly of spacers is frequently required. This necessitates that the disassembly and assembly device not only operates smoothly but also facilitates maintenance and replacement. In this embodiment, the segmented design of the extension 22 in the disassembly and assembly device allows for smoother movement of the connecting rod 50, enabling operators to easily complete the disassembly and assembly of spacers and reducing jamming and delays during operation. Simultaneously, the segmented extension 22 design also facilitates 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 routine 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, and a threaded hole is provided at the end of the connecting body 21. The operating rod 10 is a threaded rod, which passes through the threaded hole and is 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 effortless, which is suitable for operations that require large torque, such as disassembling and assembling relatively tight spacers in power lines.

[0043] In power lines, traditional tools often require significant torque to disassemble or assemble tightly secured spacers, placing high demands on the operator's physical strength and skill. The disassembly / assembly device in this embodiment, with its threaded connection design, not only enhances the stability of the device but also makes driving the operating lever 10 much easier. Even with tightly secured spacers, operators can easily complete the disassembly / assembly work. This design is particularly important in the maintenance of high-voltage lines, as it effectively reduces the physical exertion of operators and improves the safety and efficiency of the operation.

[0044] like Figures 1 to 4 As shown, in this embodiment, the clamping member 30 includes a protruding abutment portion 31 and an adjusting member 32. The first connecting seat 20 is provided with a plurality of limiting holes 23 extending along its axial direction, and the adjusting member 32 can be inserted and engaged with different limiting holes 23. This adjustable clamping member 30 design allows the disassembly and assembly device to adapt to spacer bars of different sizes, improving the versatility of the disassembly and assembly device and making it suitable for disassembling and assembling various types of spacer bars in power lines.

[0045] In power lines, spacer bars come in a variety of models and sizes. Traditional tools often require multiple clamping devices for different types of spacer bars, which is inconvenient for carrying and using these tools. The disassembly and assembly device in this embodiment, through the design of adjustable clamping devices 30, adapts to spacer bars of different sizes, greatly improving the tool's versatility. During comprehensive maintenance of power lines, this design eliminates the need for operators to carry multiple tools; they only need to adjust the fit between the adjusting device 32 and the limiting hole 23 to complete the disassembly and assembly of various types of spacer bars. This significantly improves the convenience and efficiency of the operation, reducing work interruptions and time wasted due to tool changes.

[0046] like Figure 1 , Figure 2 as well as Figure 4 As shown, in this embodiment, the disassembly and assembly device also includes an operating handle 70, which is detachably disposed at the end of the operating lever 10 away from the second connecting seat 40. The detachable operating handle 70 design not only facilitates carrying and storage, but also allows for adjustment of the handle's length and shape according to the working environment and personal habits, improving the comfort and convenience of operation. It is suitable for various working environments, such as working in narrow power facility spaces or in open fields.

[0047] In the maintenance and repair of power facilities, the working environment is diverse, and traditional tools are often difficult to adapt to various operating conditions. The disassembly and assembly device in this embodiment features a detachable operating handle 70, which not only facilitates tool carrying and storage but also allows the length and shape of the operating handle 70 to be adjusted according to the specific working environment and personal habits. This enables operators to comfortably perform spacer disassembly and assembly operations in confined spaces or open fields. This design is particularly suitable for maintenance in equipment-dense locations such as substations and distribution rooms, as well as line maintenance in open fields such as mountains and forests. It effectively improves operator efficiency and operational safety, providing an efficient and convenient solution for comprehensive maintenance and repair in the power industry.

[0048] Specifically, in this embodiment, the disassembly and assembly device drives the first connecting seat 20 to move via the operating lever 10, and uses the guide structure 60 to drive the connecting rod 50 from the retracted position to the outwardly protruding abutment position, thus achieving efficient disassembly and assembly of the spacer bar. This design not only improves the convenience and safety of disassembly and assembly, but also reduces the physical exertion of operators, effectively improving work efficiency. It is especially suitable for high-altitude working environments, providing powerful tool support for power line maintenance. Furthermore, the structural design of the disassembly and assembly device fully considers operational flexibility and versatility, adapting to spacer bars of various sizes and different working environments, greatly improving the construction efficiency and safety of the power industry. It is an indispensable and efficient tool in power maintenance and repair work. By using this device, power companies can save significant manpower and time costs while ensuring the normal operation of power facilities, providing society with a more stable and reliable power supply.

[0049] In practical applications, especially in high-altitude maintenance and repair work on power lines, such as the disassembly and assembly of spacers on high-voltage transmission towers, the disassembly and assembly device of this embodiment demonstrates its unique advantages. It is not only convenient and safe to operate, but also adaptable to spacers of various sizes and suitable for different working environments. Operators only need to drive the first connecting seat 20 via the operating lever 10 to precisely control the movement of the connecting rod 50 using the guide structure 60, accurately aligning the abutment block 51 with the spacer, achieving efficient disassembly and assembly. This design effectively reduces the time spent on high-altitude operations, lowers 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 power companies significant manpower and time costs, but also ensures the normal operation of power facilities, providing society with a more stable and reliable power supply. It is an indispensable tool in power maintenance and repair work.
