Description

Technical Field

[0001] This invention relates to the field of power tool technology, and more specifically, to a spacer bar assembly / disassembly tool. Background Technology

[0002] Spacer bars are used to prevent relative slippage between conductors or ground wires on overhead lines, ensuring the safe operation of overhead lines. Currently, overhead lines require the installation of spacer bars at close intervals to prevent slippage of conductors or ground wires.

[0003] During the installation and removal of spacers, specialized tools are required. Traditional tools are simple mechanical structures that use screwdrivers and other tools in conjunction with adjustable pliers to work on the spacers. These tools are complex in structure, have poor performance, and are cumbersome to operate, easily causing damage to the spacers. Summary of the Invention

[0004] The main objective of this invention is to provide a spacer disassembly and assembly tool to solve the problem that the operation process of spacer disassembly and assembly tools in related technologies is relatively cumbersome.

[0005] To achieve the above objectives, the present invention provides a spacer assembly / disassembly tool, comprising: a drive rod; a movable member, which moves on the drive rod when the drive rod rotates, and the movable member is spaced apart from a first end of the drive rod; a first abutment member disposed on the movable member; a connecting member disposed at the first end of the drive rod, and the drive rod and the connecting member are rotatably connected; and a linkage assembly, comprising a first connecting rod and a second connecting rod, the first end of the first connecting rod being hinged to the end of the movable member facing the first end of the drive rod, and the second end of the first connecting rod and the second connecting rod being hinged together. One end is hinged, and the second end of the second link is hinged to the connecting member; the first end of the second abutment is hinged to the first link so that the second abutment can be swingably set, the second end of the second abutment is a free end, and the second abutment has a retracted position and an outward swing position; a limiting structure is set on the first link, and the second abutment can be limited and matched with the limiting structure when it is in the outward swing position; wherein, when the moving member moves, it can drive the first abutment to move toward the second abutment so as to clamp the clamped part between the first abutment and the second abutment.

[0006] Furthermore, the limiting structure includes a limiting hole, which is provided on the corresponding first connecting rod. The diameter of the bottom of the limiting hole is smaller than the diameter of the opening of the limiting hole. The hinge point between the second abutment and the first connecting rod is located at the bottom of the limiting hole, so that the second abutment abuts against the wall of the limiting hole when it is in the retracted position and the outward swing position.

[0007] Furthermore, the spacer bar removal and installation tool also includes a rolling element, which is disposed at the second end of the second abutment.

[0008] Furthermore, the spacer bar disassembly and assembly tool also includes a reset member, which is disposed between the second abutment and the first connecting rod. The reset member applies a reset force to the second abutment to keep the second abutment in the retracted position.

[0009] Furthermore, when the second abutment moves from the retracted position to the outward swing position, the angle between the axis of the second abutment and the axis of the drive rod is between 10° and 45°.

[0010] Furthermore, the second abutment is a rod, and the cross-sectional area of ​​the rod gradually decreases from the first end to the second end of the second abutment.

[0011] Furthermore, the drive rod is a threaded rod, the connecting member is a connecting rod, the threaded rod and the connecting rod are movably connected, the threaded rod can rotate relative to the connecting rod, and a nut is provided on the moving member. The nut is sleeved on the threaded rod, and the rotation of the threaded rod causes the nut to move on the threaded rod.

[0012] Furthermore, the cross-sectional area of ​​the second link gradually decreases from the first end near the drive rod to the first end away from the drive rod.

[0013] Furthermore, the first abutting member includes a limiting part and an abutting part, with a preset included angle between the limiting part and the abutting part. The limiting part is limited and engaged with the drive rod, and the abutting part is able to abut and engage with the clamped part.

[0014] Furthermore, there are multiple linkage groups, which are spaced apart circumferentially along the drive rod. There are also multiple second abutment members, which are arranged one-to-one with each of the multiple linkage groups.

[0015] Applying the technical solution of this invention, the movable member is mounted on the drive rod, and the drive rod can drive the movable member to move when it rotates. A first abutment is mounted on the movable member, and a connecting member is mounted on the first end of the drive rod. The drive rod and the connecting member are rotatably connected. The connecting member connects the movable member and the drive rod. Specifically, the linkage group includes a first connecting rod and a second connecting rod. The second abutment is hinged to the first connecting rod and has a retracted position and an outward swing position. A limiting structure is mounted on the first connecting rod, and the second abutment can engage with the limiting structure when it is in the outward swing position. Through the above configuration, the drive rod can drive the movable member to move, thereby adjusting the distance between the first and second abutments. Specifically, the linkage group and the connecting member are passed through the spacer structure. Operating the drive rod to rotate causes the movable member to move towards the linkage group. When the second abutment contacts the spacer structure, it can move from the retracted position to the outward swing position and be limited by the limiting structure. Continuing to operate the drive rod causes the movable member to continue moving, bringing the first and second abutments closer together, thereby clamping the spacer structure. The above operation is relatively simple and can drive the spacer structure. Therefore, the technical solution of this application effectively solves the problem of the cumbersome operation process of spacer disassembly and assembly tools in related technologies.

[0025] like Figure 1 and Figure 3As shown, in this embodiment, the spacer assembly / disassembly tool includes: a drive rod 10, a movable member 20, a first abutment member 30, a connecting member 40, a linkage group 50, a second abutment member 60, and a limiting structure 70. When the drive rod 10 rotates, it drives the movable member 20 to move on the drive rod 10, and there is a gap between the movable member 20 and the first end of the drive rod 10. The first abutment member 30 is disposed on the movable member 20. The connecting member 40 is disposed on the first end of the drive rod 10, and the drive rod 10 and the connecting member 40 are rotatably connected. The linkage group 50 is connected between the movable member 20 and the first end of the drive rod 10. The linkage group 50 includes a first connecting rod 51 and a second connecting rod 52. The first end of the first connecting rod 51 is hinged to the end of the movable member 20 facing the first end of the drive rod 10, the second end of the first connecting rod 51 is hinged to the first end of the second connecting rod 52, and the second end of the second connecting rod 52 is hinged to the connecting member 40. The first end of the second abutment 60 is hinged to the first connecting rod 51 so that the second abutment 60 can be swayed. The second end of the second abutment 60 is a free end. The second abutment 60 has a retracted position and an outward swing position. A limiting structure 70 is provided on the first connecting rod 51, and the second abutment 60 can be limited and engaged with the limiting structure 70 when it is in the outward swing position. When the moving member 20 moves, it can drive the first abutment 30 to move toward the second abutment 60, so as to clamp the clamped part between the first abutment 30 and the second abutment 60.

[0026] Applying the technical solution of this embodiment, the movable member 20 is disposed on the drive rod 10, and the drive rod 10 can drive the movable member 20 to move when it rotates. A first abutment member 30 is disposed on the movable member 20, and a connecting member 40 is disposed at the first end of the drive rod 10. The drive rod 10 and the connecting member 40 are rotatably connected. The connecting member 40 connects the movable member 20 and the drive rod 10. Specifically, the linkage group 50 includes a first connecting rod 51 and a second connecting rod 52. The second abutment member 60 is hinged to the first connecting rod 51 and has a retracted position and an outward swing position. A limiting structure 70 is disposed on the first connecting rod 51, and the second abutment member 60 can be limited and engaged with the limiting structure 70 when it is in the outward swing position. Through the above arrangement, the drive rod 10 can drive the movable member 20 to move, thereby adjusting the distance between the first abutment member 30 and the second abutment member 60. Specifically, the connecting rod assembly 50 and the connecting member 40 are passed through the spacer bar structure. The driving rod 10 is rotated, causing the moving member 20 to move towards the connecting rod assembly 50. When the second abutting member 60 contacts the spacer bar structure, it can move from the retracted position to the outward swing position and be limited by the limiting structure 70. At this point, the driving rod 10 is continued to move the moving member 20, causing the first abutting member 30 and the second abutting member 60 to move closer together, thereby clamping the spacer bar structure. The above operation is relatively simple and can drive the spacer bar structure. Therefore, the technical solution of this embodiment effectively solves the problem of the cumbersome operation process of spacer bar assembly and disassembly tools in related technologies.

[0027] Specifically, this design allows the spacer assembly / disassembly tool to adapt to spacers of different sizes, improving its versatility and flexibility. It is suitable for the installation and disassembly of spacers in projects such as power line and bridge construction. In practical applications, this design significantly improves work efficiency and reduces operational delays caused by tool size mismatches. Especially in high-altitude operations on power towers or bridges, it not only increases assembly / disassembly speed but also ensures operational safety.

[0028] like Figures 1 to 3 As shown, in this embodiment, the limiting structure 70 includes a limiting hole 71, which is disposed on the corresponding first connecting rod 51. The diameter of the bottom of the limiting hole 71 is smaller than the diameter of the opening of the limiting hole 71. The hinge point between the second abutment member 60 and the first connecting rod 51 is located at the bottom of the limiting hole 71, so that the second abutment member 60 abuts against the wall of the limiting hole 71 when it is in the retracted position and the outward swing position. The limiting hole 71 has a simple structure and is easy to manufacture.

[0029] Specifically, the aforementioned limiting structure 70 ensures the stability of the second abutment 60 during use, preventing unnecessary swaying due to external forces during operation, thus improving work efficiency. This is especially important in high-altitude operations, reducing safety risks for operators. Even under strong winds or complex operating conditions, the second abutment 60 remains stable, preventing tool loss of control due to unexpected swaying. This stability is crucial for ensuring operator safety, particularly in high-altitude operations on power lines or bridges.

[0030] like Figures 1 to 3 As shown, in this embodiment, the spacer bar removal and installation tool also includes a rolling element 81, which is disposed at the second end of the second abutment 60. The rolling element 81 makes the contact between the second abutment 60 and the clamped part smoother, reduces friction, and makes the operation more labor-saving. It is suitable for scenarios that require frequent removal and installation of spacers, such as power line maintenance and bridge repair, and can significantly improve work efficiency.

[0031] In practical applications, the use of the rolling element 81 greatly reduces the physical exertion of operators. Especially in the maintenance of power lines, operators need to frequently disassemble and assemble spacers. The smooth contact of the rolling element 81 makes this process more labor-saving and improves work efficiency.

[0032] like Figures 1 to 3 As shown, in this embodiment, the spacer bar disassembly and assembly tool further includes a reset member 82. The reset member 82 is disposed between the second abutment member 60 and the first connecting rod 51. The reset member 82 applies a reset force to the second abutment member 60 to keep the second abutment member 60 in the retracted position. The design of the reset member 82 enables the tool to automatically reset when not in use, reducing operation steps and improving ease of operation. It is suitable for scenarios that require rapid switching of working states, such as emergency repairs and rapid installation, and can effectively save operation time.

[0033] Specifically, this design is particularly effective in emergency repair scenarios. Operators can quickly reset the tools after completing a disassembly and assembly, preparing for the next operation, which greatly saves preparation time and improves repair efficiency.

[0034] like Figures 1 to 3 As shown, in this embodiment, when the second abutment member 60 moves from the retracted position to the outward swing position, the angle between the axis of the second abutment member 60 and the axis of the drive rod 10 is between 10° and 45°. This angle range ensures the flexibility and stability of the second abutment member 60 during operation, enabling operation in confined spaces and making it suitable for the disassembly and assembly of spacer bars in complex environments such as power towers, thus expanding the tool's applicability.

[0035] Specifically, in this embodiment, the included angle is 30°. Of course, the included angle can also be 15°, 20°, 25°, 35° or other angles.

[0036] In practical applications, the flexibility of this design allows operators to accurately install and remove spacers even in narrow or complex spaces, such as in dense cable areas of power towers where operating space is limited. This design makes the tool better suited to such environments, improving operational flexibility and safety.

[0037] The second abutment 60 is a rod 61, and its cross-sectional area gradually decreases from the first end to the second end. This gradual design allows the second abutment 60 to better adapt to the shape of the clamped part when in contact with it, improving the stability and reliability of the clamping. It is suitable for the disassembly and assembly of irregularly shaped spacers, such as special spacers in power towers, and can effectively improve the efficiency of disassembly and assembly.

[0038] In practice, the aforementioned design of the gradually widened rod 61 can better match spacers of different shapes, improving the clamping accuracy and stability. Especially in power towers, the shape and size of spacers may vary depending on design requirements. This design allows the tool to better adapt to various situations, improve assembly and disassembly efficiency, and reduce operational difficulty.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the drive rod 10 is a threaded rod, and the connector 40 is a connecting rod. The threaded rod and the connecting rod are movably connected, and the threaded rod can rotate relative to the connecting rod. A nut 21 is provided on the moving part 20, and the nut 21 is sleeved on the threaded rod. The rotation of the threaded rod causes the nut 21 to move on the threaded rod. The above-mentioned threaded connection method allows the rotation of the drive rod 10 to precisely control the movement distance of the moving part, improving the operating accuracy of the tool. It is suitable for scenarios that require precise control of disassembly and assembly force, and can effectively avoid equipment damage caused by improper operation.

[0040] It should be noted that a connecting bearing is provided between the connecting rod and the threaded rod.

[0041] Specifically, in the maintenance of electrical equipment, this design ensures control over the force applied during disassembly and assembly, preventing equipment damage or disassembly / assembly failure due to excessive or insufficient force. This precise control is especially crucial when handling high-voltage electrical equipment, ensuring the safety of both the equipment and the operators.

[0042] like Figures 1 to 3As shown, in this embodiment, the cross-sectional area of ​​the second link 52 gradually decreases from the first end near the drive rod 10 to the direction away from the first end of the drive rod 10. This design improves the strength and stability of the link assembly 50, enabling the tool to maintain normal operation under heavy loads, and is suitable for scenarios requiring the resistance to large external forces. In strong winds, this design allows the tool to better resist external forces, maintaining operational stability and safety. Especially in high-altitude operations on power lines, where strong winds are a common working environment, this design effectively reduces the risk of tool loss of control due to wind.

[0043] like Figure 1 and Figure 2 As shown, in this embodiment, the first abutting member 30 includes a limiting part 31 and an abutting part 32. A preset included angle exists between the limiting part 31 and the abutting part 32. The limiting part 31 engages with the driving rod 10, and the abutting part 32 engages with the clamped part. The design of the limiting part 31 and the abutting part 32 allows the first abutting member 30 to better adapt to clamped parts of different shapes, improving the tool's versatility. It is suitable for the disassembly and assembly of spacer bars in various projects such as power towers, effectively improving work efficiency.

[0044] In practice, the aforementioned first abutment 30 can better adapt to spacers of various shapes, improving the versatility and adaptability of the tool. Especially in the maintenance of power towers and bridge structures, spacers in different locations may have different shapes and sizes. This type of tool can better meet various disassembly and assembly needs and improve work efficiency.

[0045] Specifically, the movable part 20 is provided with multiple recesses, which are arranged along the axial direction of the drive rod 10. The limiting part includes a limiting block, which can be inserted into different recesses, thereby adjusting the distance between the first abutting part 30 and the second abutting part 60, and thus adapting to spacers of different sizes. This eliminates the need for long-term operation of the drive rod 10, thereby reducing operation time.

[0046] like Figure 1 and Figure 2 As shown, in this embodiment, there are multiple linkage groups 50, which are spaced apart circumferentially along the drive rod 10. There are also multiple second abutment members 60, each corresponding to one of the linkage groups 50. This multi-linkage group 50 design improves the tool's clamping force and operational stability, maintaining good working condition when simultaneously clamping spacer bars. It is suitable for the maintenance and repair of large-scale power lines, significantly improving work efficiency and reducing the labor intensity of operators.

[0047] Specifically, in the maintenance and repair of large-scale power lines, this multi-link assembly 50 design can handle multiple spacers simultaneously, significantly improving work efficiency. Especially in emergency situations where a rapid restoration of power supply is required, this design can quickly complete the disassembly and assembly of large-scale spacers, reducing the labor intensity of operators and improving the safety and reliability of the operation.

[0048] The spacer assembly / disassembly tool of this embodiment is designed so that the rotation of the drive rod 10 drives the moving part 20 to move on the drive rod 10, and then the connecting rod assembly 50 makes the first abutment part 30 and the second abutment part 60 move closer or further apart, achieving efficient assembly / disassembly of the spacer. Meanwhile, the swingable design of the second abutment part 60, and its cooperation with the limiting structure 70, makes the tool more stable and easier to operate during use. Furthermore, the rolling part 81 and the reset part 82 further improve the tool's practicality and operational comfort. The overall structure is compact, the operation is flexible, effectively improving work efficiency and reducing the labor intensity of operators, demonstrating significant application benefits.

[0049] In practical applications, this tool not only significantly improves the efficiency of disassembling and assembling spacers in power line and other engineering projects, but also reduces safety accidents caused by improper operation through its precise control and stable performance, providing a safer and more efficient solution for engineering operations. Simultaneously, its compact design and flexible operation allow operators to complete tasks more easily in complex working environments, reducing the physical burden of long-term work and improving comfort and safety. Especially in emergency repairs, large-scale maintenance, or operations in complex environments, the high efficiency and stability of this disassembly and assembly tool can significantly shorten operation time, improve work quality, effectively ensure the safe operation of power supply and infrastructure, reduce maintenance costs, and provide strong support for engineering operations.

[0050] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0051] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0052] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.
