[0025] like Figure 1 and Figure 3As shown, in the present embodiment, the spacer rod disassembly and assembly tool comprises: a driving rod 10, a moving member 20, a first abutment member 30, a connecting member 40, a connecting rod group 50, a second abutment member 60 and a limiting structure 70. When the driving rod 10 rotates, the moving member 20 is driven to move on the driving rod 10, and there is a gap between the moving member 20 and the first end of the driving rod 10. The first abutment member 30 is arranged on the moving member 20. The connecting member 40 is arranged on the first end of the driving rod 10, and the driving rod 10 is rotatably connected with the connecting member 40. The connecting rod group 50 is connected between the moving member 20 and the first end of the driving rod 10, and the connecting rod group 50 comprises a first connecting rod 51 and a second connecting rod 52, the first end of the first connecting rod 51 is hingedly connected to the end of the moving member 20 towards the first end of the driving rod 10, the second end of the first connecting rod 51 is hingedly connected to the first end of the second connecting rod 52, and the second end of the second connecting rod 52 is hingedly connected to the connecting member 40. The first end of the second abutment member 60 is hingedly connected to the first connecting rod 51 so that the second abutment member 60 can be swingably arranged, and the second end of the second abutment member 60 is a free end. The second abutment member 60 has a recovery position and an outward swing position. The limiting structure 70 is arranged on the first connecting rod 51, and the second abutment member 60 can be limitedly matched with the limiting structure 70 when it is in the outward swing position. Among them, when the moving member 20 moves, it can drive the first abutment member 30 to move toward the second abutment member 60, so that the clamped member is clamped between the first abutment member 30 and the second abutment member 60.

[0026] The technical scheme of the present embodiment is applied, the moving member 20 is arranged on the driving rod 10, and the driving rod 10 can drive the moving member 20 to move when it rotates. The first abutment member 30 is arranged on the moving member 20, and the connecting member 40 is arranged on the first end of the driving rod 10, and the driving rod 10 is rotatably connected with the connecting member 40. The connecting member 40 is connected between the moving member 20 and the driving rod 10, specifically, the connecting rod group 50 includes a first connecting rod 51 and a second connecting rod 52, and the second abutment member 60 is hingedly connected with the first connecting rod 51 and has a recovery position and an outward swing position, and the limiting structure 70 is arranged on the first connecting rod 51, and the second abutment member 60 can cooperate with the limiting structure 70 when it is in the outward swing position. Through the above-mentioned setting, the driving rod 10 can drive the moving member 20 to move and then adjust the distance between the first abutment member 30 and the second abutment member 60. Specifically, the connecting rod group 50 and the connecting member 40 are passed through the spacer rod structure, and the driving rod 10 is operated to rotate so that the movable member 20 moves toward the connecting rod group 50. When the second abutment member 60 contacts the spacer rod structure, the second abutment member 60 can be moved from the recovery position to the outward swing position and limited by the limiting structure 70. At this time, the driving rod 10 is continued to be operated so that the movable member 20 continues to move and the first abutment member 30 and the second abutment member 60 are close to each other, thereby clamping the spacer rod structure. The above operation is relatively simple and can realize the driving of the spacer rod structure. Therefore, the technical solution of this embodiment effectively solves the problem that the operation process of the spacer rod disassembly and assembly tool in the related art is relatively cumbersome.

[0027] Specifically, this design enables the spacer bar disassembly and assembly tool to adapt to spacer bars of different sizes, improving its versatility and flexibility, and is suitable for the installation and removal of spacer bars in projects such as power lines and bridge construction. In practical applications, this design of disassembly and assembly tool greatly improves work efficiency and reduces operation delays caused by tool size mismatch, especially in high-altitude operations on power towers or bridges, which not only improves the disassembly and assembly speed, but also ensures the safety of operation.

[0028] like Figures 1 to 3 As shown, in this embodiment, the limiting structure 70 includes a limiting hole 71, which is arranged on the corresponding first connecting rod 51, and the aperture of the bottom of the limiting hole 71 is smaller than the aperture of the mouth of the limiting hole 71. The hinge point between the second abutting member 60 and the first connecting rod 51 is located at the bottom of the limiting hole 71, so that the second abutting member 60 abuts against the hole wall of the limiting hole 71 when it is located at the recovery position and the swing-out position. The limiting hole 71 has a simple structure and is easy to process.

[0029] Specifically, the above-mentioned limiting structure 70 ensures the stability of the second abutment member 60 during use, avoids unnecessary swinging due to external forces during operation, improves work efficiency, and can reduce the safety risks of operators, especially during high-altitude operations. Even in strong winds or complex operating conditions, the second abutment member 60 can remain stable, avoiding the tool from losing control due to unexpected swinging, especially during high-altitude operations on power lines or bridges, such stability is crucial to ensure the safety of operators.

[0030] like Figures 1 to 3 As shown, in this embodiment, the spacer bar disassembly and assembly tool further includes a rolling member 81, and the rolling member 81 is arranged at the second end of the second abutting member 60. The arrangement of the rolling member 81 makes the second abutting member 60 contact the clamped member more smoothly, reduces friction, and makes the operation more labor-saving. It is suitable for scenes where spacer bars need to be frequently disassembled and assembled, such as power line maintenance, bridge inspection, etc., 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, where operators need to frequently disassemble and assemble the spacer bars. 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 rod disassembly and assembly tool further includes a reset member 82, which is disposed between the second abutment member 60 and the first connecting rod 51, and 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, reduces the operation steps, improves the convenience of operation, and is suitable for scenes that require rapid switching of working states, such as emergency repairs, rapid installation, etc., which can effectively save operation time.

[0033] Specifically, the application effect of this design is particularly obvious in emergency repair scenarios. The operator can quickly reset the tool after completing a disassembly and assembly and prepare 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 is moved 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 driving rod 10 is between 10° and 45°. The above angle range ensures the flexibility and stability of the second abutment member 60 during operation, and can be operated in a small space, which is suitable for the disassembly and assembly of spacer bars in complex environments such as power towers, thereby improving the scope of application of the tool.

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

[0036] In practical applications, the flexibility of this design enables operators to accurately disassemble and assemble spacers even in narrow or complex spaces. For example, in densely packed cable areas of power towers, where operating space is limited, tools of this design can better adapt to such environments and improve operational flexibility and safety.

[0037] The second abutment member 60 is a rod body 61, and the cross-sectional area of ​​the rod body 61 gradually decreases in the direction from the first end of the second abutment member 60 to the second end of the second abutment member 60. The above-mentioned gradual change design enables the second abutment member 60 to better adapt to the shape of the clamped member when in contact with the clamped member, improves the stability and reliability of clamping, and is suitable for the disassembly and assembly of irregularly shaped spacers, such as special spacers in power towers, and can effectively improve the disassembly and assembly efficiency.

[0038] In actual operation, the above-mentioned rod body 61 with a gradually varying width design can better match spacer bars of different shapes, thereby improving the clamping accuracy and stability. Especially in power towers, the shape and size of the spacer bars may vary according to design requirements. Tools of this design can better adapt to various situations, improve disassembly and assembly efficiency, and reduce operation difficulty.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the driving rod 10 is a threaded rod, the connecting member 40 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 the moving member 20 is provided with a nut member 21, the nut member 21 is sleeved on the threaded rod, and the threaded rod rotates to move the nut member 21 on the threaded rod. The above-mentioned threaded connection method enables the rotation of the driving rod 10 to accurately control the moving distance of the moving member, improves the operating accuracy of the tool, is suitable for scenes that require precise control of the 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 power equipment, this design can ensure force control during the disassembly and assembly process, avoiding equipment damage or disassembly and assembly failure due to excessive or insufficient force. Especially when handling high-voltage power equipment, this precise control is crucial to ensuring the safety of equipment and operators.

[0042] like Figures 1 to 3As shown, in this embodiment, the cross-sectional area of ​​the second connecting rod 52 gradually increases from the first end close to the driving rod 10 to the first end away from the driving rod 10. This design improves the strength and stability of the connecting rod assembly 50, and can maintain the normal operation of the tool under a large load, and is suitable for scenes that need to withstand large external forces. In strong wind weather, tools of this design can better resist the influence of external forces and maintain the stability and safety of operation, especially in high-altitude operations on power lines. Strong winds are a common working environment, and tools of this design can effectively reduce the risk of tool loss of control due to wind.

[0043] like Figure 1 and Figure 2 As shown, in this embodiment, the first abutment member 30 includes a limiting portion 31 and an abutment portion 32, and there is a preset angle between the limiting portion 31 and the abutment portion 32. The limiting portion 31 is limitedly matched with the driving rod 10, and the abutment portion 32 can abut and match with the clamped member. The design of the limiting portion 31 and the abutment portion 32 enables the first abutment member 30 to better adapt to clamped members of different shapes, improves the versatility of the tool, is suitable for the disassembly and assembly of spacer bars in different projects such as power towers, and can effectively improve work efficiency.

[0044] In actual operation, the above-mentioned first abutment member 30 can better adapt to spacer bars of various shapes, thereby improving the versatility and adaptability of the tool. Especially in the maintenance of power towers and bridge structures, the spacer bars at different positions may have different shapes and sizes. Tools of this design can better meet various disassembly and assembly requirements and improve work efficiency.

[0045] Specifically, a plurality of recesses are provided on the movable part 20, and the plurality of recesses are provided along the axial direction of the driving rod 10. The limiting part includes a limiting block, and the limiting block can be inserted into different recesses, so as to adjust the distance between the first abutment part 30 and the second abutment part 60, so as to adapt to spacer rods of different sizes, that is, there is no need to operate the driving rod 10 for a long time, so as to reduce the operation time.

[0046] like Figure 1 and Figure 2 As shown, in this embodiment, there are multiple connecting rod groups 50, and the multiple connecting rod groups 50 are arranged at intervals along the circumference of the driving rod 10. There are multiple second abutment members 60, and the multiple second abutment members 60 are arranged one-to-one corresponding to the multiple connecting rod groups 50. The design of this multiple connecting rod group 50 improves the clamping force and operation stability of the tool, can maintain a good working state when clamping the spacer rods at the same time, is suitable for maintenance and repair of large-scale power lines, can significantly improve work efficiency, and reduce the labor intensity of operators.

[0047] Specifically, in the maintenance and inspection of large-scale power lines, the design of the multi-link group 50 can handle multiple spacer bars at the same time, significantly improving the operating efficiency. Especially in emergency situations where power supply needs to be quickly restored, the tool of this design can quickly complete the disassembly and assembly of large-scale spacer bars, reducing the labor intensity of operators and improving the safety and reliability of operations.

[0048] The design of the spacer rod disassembly and assembly tool of this embodiment drives the moving member 20 to move on the driving rod 10 through the rotation of the driving rod 10, and then makes the first abutment member 30 and the second abutment member 60 approach or move away from each other through the connecting rod group 50, thereby realizing efficient disassembly and assembly of the spacer rod. At the same time, the swingable design of the second abutment member 60 and the cooperation with the limiting structure 70 make the tool more stable during use and more convenient to operate. In addition, the setting of the rolling member 81 and the reset member 82 further improves the practicality and operating comfort of the tool, the overall structure is compact, the operation is flexible, the work efficiency is effectively improved, the labor intensity of the operator is reduced, and it has significant application benefits.

[0049] In practical applications, this tool can not only significantly improve the efficiency of disassembly and assembly of spacers in power line projects, but also reduce safety accidents caused by improper operation through its precise control and stable performance, providing a safer and more efficient solution for engineering operations. At the same time, its compact design and flexible operation mode also enable operators to complete tasks more easily when facing complex working environments, reduce the physical burden of operators due to long-term operations, and improve the comfort and safety of operations. Especially in emergency repairs, large-scale overhauls or operations in complex environments, the high efficiency and stability of this disassembly and assembly tool can significantly shorten the operation time, improve the quality of operations, 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 the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

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

[0052] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
