Description

Technical Field

[0001] This utility model relates to the field of assembly and disassembly pliers, specifically an overhead line assembly and disassembly pliers. Background Technology

[0002] As a core component of the power transmission system, overhead lines require specialized clamping tools for installation, maintenance, and replacement. These tools must meet the core requirements of stable clamping, compatibility with multiple wire diameters, and safe insulation for high-altitude operations. With the expansion of power grid coverage and the increasing diversity of overhead line diameters, coupled with complex working environments such as wind interference and high-altitude swaying, existing clamping tools are gradually revealing their technical shortcomings.

[0003] Existing overhead line clamps mostly rely solely on the main clamping component to secure the line. During high-altitude operations, the line is susceptible to wind or operational swaying, making it difficult to maintain a stable position using only the main clamping force. On the one hand, the line is prone to radial displacement along the clamp jaws or even detachment, leading to work interruption. If the line detaches while energized, it may cause electric shock, falling line to the ground, or other safety accidents. On the other hand, line swaying can cause misalignment between the line and the insulating components inside the clamp jaws, allowing the metal clamp to directly contact the line, damaging the insulation barrier and significantly increasing the risk of electric shock for operators. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an overhead line assembly and disassembly clamp, which solves the problems described in the background section above.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an overhead line installation and removal clamp, including a mounting base and a clamping component located in the inner cavity of the mounting base. A fixing frame is provided on the front side of the mounting base, a clamping component is provided in the inner cavity of the fixing frame, a deformation component is provided in the inner cavity of the clamping component, a fixing plate is provided at the bottom of the fixing frame, and auxiliary components are symmetrically arranged on the inner side of the fixing plate.

[0006] As a preferred embodiment of this utility model, the auxiliary component includes a support rod rotatably mounted on the lower front side of the fixed plate, a spring between the two sets of support rods, an auxiliary frame on the inner side of one end of the support rod, and electromagnets symmetrically arranged at both ends of the auxiliary frame.

[0007] As a preferred embodiment of this utility model, the inner cavity of the mounting base is provided with a mounting cavity, and a support frame is fixedly installed on the rear side of the mounting base.

[0008] As a preferred embodiment of the present invention, the clamping assembly includes a hydraulic cylinder installed in the mounting cavity. The output end of the hydraulic cylinder is inserted into the inner cavity of the fixing frame and a connecting rod is symmetrically installed thereon. One end of the connecting rod is rotatably mounted to a mounting frame, and one end of the mounting frame is rotatably mounted to a fixing clamp. The upper and lower ends of the fixing clamp are rotatably mounted to connecting rods, and the other end of the connecting rods is rotatably mounted to the fixing frame.

[0009] As a preferred embodiment of this utility model, the inner cavity of the fixing clamp is equipped with deformation components at equal intervals, and the bottom of the fixing clamp is connected to the support rod through the fixing rod.

[0010] As a preferred embodiment of the present invention, the deformation component includes a placement cavity opened inside the fixing clamp, a buffer spring installed in the placement cavity, and a slide rod slidably installed at one end of the buffer spring.

[0011] As a preferred embodiment of this utility model, the cross-section of the slide rod is T-shaped, and an insulating flexible plate is fixedly installed at one end of the slide rod.

[0012] As a preferred embodiment of this utility model, the cross-section of the auxiliary frame is arc-shaped.

[0013] This utility model has the following beneficial effects: 1. Auxiliary components are symmetrically arranged on the inner side of the fixing plate. When the fixing clamp is closed, it will drive the support rod to rotate synchronously around the rotation connection point between the support rod and the fixing plate. At the same time, the spring between the two sets of support rods is in a naturally extended state. The elastic force pushes the support rod, causing the auxiliary frame on the inner side of the support rod end to move closer to the line. Since the cross-section of the auxiliary frame is arc-shaped, it can fit against the outer wall of the overhead line, forming auxiliary support from the side of the line. This not only prevents the line from accidentally falling off during installation and removal, but also prevents the line from misaligning with the insulating flexible plate inside the fixing clamp due to shaking. This ensures that the insulating flexible plate always covers the contact area between the line and the metal fixing clamp, blocking the current conduction path and indirectly protecting the operator's safety from electric shock.

[0014] 2. By incorporating a deformation component within the clamping assembly's inner cavity, when the clamping clamp closes to hold the line, the outer wall of the line first contacts the insulating flexible plate inside the clamp. As the clamp continues to close, the line exerts pressure on the insulating flexible plate. Under this pressure, the insulating flexible plate transmits the force to the slide rod fixedly connected to it. The slide rod then compresses the internal buffer spring, allowing the insulating flexible plate to fit tightly against the outer wall of overhead lines of different diameters. This prevents the clamping from loosening or damaging the line due to differences in line diameter. While adapting to the line, the insulating flexible plate also blocks current conduction between the line and the clamping clamp, preventing the risk of electric shock during operation and ensuring the safety of operators.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements 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 of this utility model.

[0019] The following is based on Figure 1 - Figure 6 This invention describes the overhead line assembly / disassembly pliers provided in an embodiment of the present invention.

[0020] Please see Figure 1 - Figure 6This utility model provides a technical solution: an overhead line installation and removal clamp, including a mounting base 1 and a clamping component 4 located in the inner cavity of the mounting base 1. A fixing frame 3 is provided on the front side of the mounting base 1, the clamping component 4 is provided in the inner cavity of the fixing frame 3, and a deformation component 5 is provided in the inner cavity of the clamping component 4. A fixing plate 7 is provided at the bottom of the fixing frame 3, and auxiliary components 8 are symmetrically arranged on the inner side of the fixing plate 7. The auxiliary components 8 include a support rod 801 rotatably installed below the front side of the fixing plate 7, a spring 802 is provided between the two sets of support rods 801, an auxiliary frame 803 is provided on the inner side of one end of the support rod 801, and electromagnets 804 are symmetrically arranged at both ends of the auxiliary frame 803. The cross-section of the auxiliary frame 803 is arc-shaped. In this embodiment, when the clamping clamp 405 rotates to clamp the line, the bottom of the clamping clamp 405 is connected to the support rod 801 via a fixing rod. When the clamping clamp 405 closes, it drives the support rod 801 to rotate synchronously around its rotational connection point with the fixing plate 7. Simultaneously, the spring 802 between the two sets of support rods 801 is in a naturally extended state, pushing the support rod 801 with elastic force, causing the auxiliary frame 803 on the inner side of the end of the support rod 801 to move closer to the line. Since the auxiliary frame 803 has an arc-shaped cross-section, it can fit against the outer wall of the overhead line, forming auxiliary support from the side of the line. This not only prevents the wire from accidentally falling off during installation and removal, but also prevents the wire from becoming misaligned with the insulating flexible plate 6 inside the fixing clamp 405 due to shaking. It ensures that the insulating flexible plate always covers the contact area between the wire and the metal fixing clamp 405, blocking the current conduction path and indirectly protecting the operator's safety from electric shock. If it is necessary to further improve the fixing stability, the electromagnets 804 at both ends of the auxiliary frame 803 can be energized. After the electromagnets 804 are energized, they generate magnetic force and attract the metal conductor part of the overhead line, forming an additional fixing force, further restricting the displacement of the wire, and ensuring accurate and stable installation and removal operations.

[0021] Specifically, the inner cavity of the mounting base 1 is provided with a mounting cavity 101, and a support frame 2 is fixedly installed on the rear side of the mounting base 1. In this embodiment, the entire assembly / disassembly clamp is fixed to the overhead line operation platform or related operating bracket by the support frame 2 on the rear side of the mounting base 1, ensuring the overall stability of the equipment and providing a solid foundation for subsequent assembly / disassembly operations.

[0022] Specifically, the clamping assembly 4 includes a hydraulic cylinder 401 installed in the mounting cavity 101. The output end of the hydraulic cylinder 401 is inserted into the inner cavity of the fixing frame 3 and a connecting rod 402 is symmetrically installed. One end of the connecting rod 402 is rotatably mounted with a mounting frame 403. One end of the mounting frame 403 is rotatably mounted with a fixing clamp 405. The upper and lower ends of the fixing clamp 405 are rotatably mounted with connecting rods 404. The other end of the connecting rods 404 is rotatably mounted on the fixing frame 3. Deformation assemblies 5 are installed at equal intervals in the inner cavity of the fixing clamp 405. The bottom of the fixing clamp 405 is connected to the support rod 801 through a fixing rod. The deformation assembly 5 includes a placement cavity 501 opened inside the fixing clamp 405. A buffer spring 502 is installed in the placement cavity 501. One end of the buffer spring 502 is slidably mounted with a slide rod 503. The cross-section of the slide rod 503 is a "T" shaped structure. One end of the slide rod 503 is fixedly mounted with an insulating soft plate 6. In this embodiment, when it is necessary to clamp an overhead line, when the operator controls the hydraulic cylinder 401 to drive the fixing clamp 405 to close, the fixing rod at the bottom of the fixing clamp 405 will synchronously drive the support rod 801 to rotate, so that the auxiliary frame 803 automatically moves closer to the line, thereby closing the fixing clamp 405 and clamping the overhead line. When the fixing clamp 405 closes to clamp the line, the outer wall of the line first contacts the insulating flexible plate 6 on the inner side of the fixing clamp 405. As the fixing clamp 405 continues to close, the line exerts pressure on the insulating flexible plate 6. After the insulating flexible plate 6 is under pressure, it transmits the pressure to the slide rod 503 fixedly connected to it. The slide rod 503 will squeeze the internal buffer spring 502 to slide, so that the insulating flexible plate 6 can closely fit the outer wall of the overhead line of different diameters, avoiding the clamping loosening or damage to the line due to the difference in line diameter. While adapting to the line, the insulating flexible plate 6 can block the current conduction between the line and the fixing clamp 405, preventing the risk of electric shock during operation and ensuring the safety of the operator.

[0023] The working principle and usage process of this utility model are as follows: The mounting bracket 2 on the rear side of the mounting base 1 secures the clamping pliers to the work platform or support, ensuring overall stability. The mounting cavity 101 of the mounting base 1 provides installation space for the clamping assembly 4. Activating the hydraulic cylinder 401 within the mounting cavity 101 drives the symmetrical connecting rod 402, causing the mounting frame 403 to move. The fixing clamp 405 is rotatably connected to the fixing frame 3 via a connecting rod 404, opening and closing with the mounting frame 403 around the connecting rod 404. When the hydraulic cylinder 401 extends, the fixing clamp 405 closes to clamp the cable; when it retracts, it opens to release the cable. The line presses against the inner insulating flexible plate 6, and the pressure is transmitted to the slide rod 503. The slide rod 503 compresses the buffer spring 502 in the placement cavity 501 and slides, so that the insulating flexible plate 6 adapts to lines of different diameters. This prevents the clamp from loosening and damaging the line, and also blocks current conduction to prevent electric shock. When the fixing clamp 405 is closed, the fixing rod drives the support rod 801 to rotate around the fixing plate 7. The spring 802 between the two sets of support rods 801 pushes the arc-shaped auxiliary frame 803 to fit against the side of the line, preventing the line from shifting and falling off. When it is necessary to strengthen the stability, the electromagnet 804 of the auxiliary frame 803 is energized to attract the metal conductor of the line, further limiting the displacement and ensuring accurate and safe installation and removal.
