Description
Technical Field
[0001] This invention relates to the field of live-line work technology for power distribution networks, specifically to a clamp device for live-line construction work in power distribution projects. Background Technology
[0002] Currently, in power distribution network operations, live-line working techniques can effectively avoid economic losses caused by power outages, which is of great significance for improving the overall power supply reliability of the power distribution network. Current live-line working techniques are generally divided into live-line working techniques and bypass working techniques. Live-line working techniques refer to maintenance and testing operations on high-voltage lines without power interruption. The tools used typically include wire clamp structures with grounding functions to divert power to the ground, effectively ensuring the personal safety of the workers. Bypass working techniques refer to temporarily replacing the distribution line with a transfer line to provide power, enabling power outage maintenance of high-voltage lines without interrupting power supply to users. The tools used typically include wire clamp structures with cable transition functions to effectively transfer power supply to the line.
[0003] In power transmission, industrial power distribution, and communication line systems, wire clamps are key components that connect conductors to equipment (such as poles, switchgear, and transformers). If the conductor specifications are incompatible with the wire clamp, poor contact can easily occur, leading to increased contact resistance between the wire clamp and the conductor. This can cause localized overheating at the contact point, burning the wire clamp body and the conductor insulation layer, and causing phase-to-phase short circuits or grounding faults. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides a wire clamp device for live-line construction in power distribution engineering, including a fixing plate, a lead wire support plate fixedly connected to the outer wall of the fixing plate, and a conductor support plate fixedly connected to the outer wall of the fixing plate, and further comprising: The wire clamping mechanism has an outer wall that meshes with the inner wall of the wire support plate. The wire clamping mechanism is used to clamp the wire. The stabilizing mechanism is fixedly connected to the outer wall of the conductor support plate. The stabilizing mechanism is used to stabilize and clamp the conductor. The fixing mechanism is fixedly connected to the outer wall of the fixing plate at its outer wall. The fixing mechanism is used to assist in clamping the lead wire. A wire bolt is engaged with the inner wall of the wire support plate, a fixing ring is fixedly connected to the outer wall of the wire bolt, and an adapter ring is rotatably connected to the end of the wire bolt away from the fixing ring.
[0005] After the lead wire is fixed, the staff uses a special gun to fix the gun and the fixing ring together. Then, the entire wire clamp device is lifted to the position of the wire to be connected, and then the wire clamp device is hung on the wire. At this time, the staff can rotate the gun to turn the fixing ring, so that the fixing ring drives the wire bolt to rotate, and then the wire bolt drives the adapter ring to move towards the anti-slip component. Preferably, the wire clamping mechanism includes: A wire clamping assembly, the outer wall of which is fixedly connected to the outer wall of the adapter ring; The contact component is fixedly connected to the inner wall of the wire clamping component at its outer wall.
[0006] Preferably, the stabilizing mechanism includes: A sliding component, the outer wall of which is fixedly connected to the outer wall of the wire support plate; The limiting component is slidably connected to the inner wall of the sliding component.
[0007] Preferably, the fixing mechanism includes: The auxiliary component is fixedly connected to the outer wall of the fixed plate via a connector. The connector includes a lead bolt that engages with the inner wall of the lead support plate, a lead fixing terminal that is rotatably connected to the outer wall of the lead bolt, and a lead fixing groove that is provided on the outer wall of the fixing plate. In use, first place the lead wire to be connected to the power supply into the lead wire fixing groove, then tighten the lead wire bolt to move the lead wire fixing bolt towards the lead wire fixing groove. Then the lead wire fixing bolt drives the lead wire fixing terminal to move towards the lead wire fixing groove. When the outer wall of the lead wire fixing terminal contacts the lead wire to be connected to the power supply, continue to tighten the lead wire bolt so that the lead wire fixing terminal interacts with the lead wire fixing groove, thereby fixing the lead wire to be connected to the power supply. The anti-slip component is fixedly connected to the inner wall of the fixing plate at its outer wall.
[0008] Preferably, the wire clamping assembly includes a support plate fixedly connected to the outer wall of the adapter ring, two rotating plates rotatably connected to the outer wall of the support plate, and a plurality of chain plates rotatably connected to the outer walls of the two rotating plates, with the plurality of chain plates rotatably connected to each other end to end.
[0009] The movement of the adapter ring will also drive the support plate to move synchronously. When it moves to a certain position, the rotating plate connected to the support plate and the chain plate connected to the rotating plate will restrict the wire to the outer wall of the anti-slip component. During the process of several chain plates contacting the wire and fixing the wire, the chain plates will be pressed against the outer wall of the wire by the action of the rotating plates on both sides. The telescopic rods set on the inner wall of the rotating plate will exert force on the rotating plates on both sides, thus making the chain plates press tightly against the outer wall of the wire. Due to the characteristics of the chain plates, the chain plates can change with the shape of the outer wall of the wire, which increases the contact area between the wire clamp device and the wire. This reduces the probability of problems such as local overheating caused by the wire not being tightly pressed against the wire clamp, and reduces the probability of wire clamp and wire failure. Preferably, the contact assembly includes several fixing blocks 1 fixedly connected to the inner walls of the two rotating plates, the several fixing blocks 1 are in pairs, a telescopic rod is rotatably connected to the inner wall of the fixing blocks 1, and several fixing blocks 2 are rotatably connected to the outer wall of the end of the telescopic rod away from the fixing blocks 1, the several fixing blocks 2 are in pairs. Several fixed blocks are fixedly connected to the support plate at their outer walls.
[0010] Preferably, the sliding assembly includes a ratchet ring fixedly connected to the outer wall of the wire support plate, a radial groove on the inner wall of the wire bolt, and a longitudinal groove on the inner wall of the wire bolt.
[0011] Preferably, the limiting component includes a slide rod slidably connected to the inner wall of the longitudinal slide groove, a slide tube fixedly connected to the outer wall of the slide rod, a spring fixedly connected to the inner wall of the slide tube, and a limiting rod fixedly connected to the outer wall of the spring.
[0012] When the wire clamp device secures the wire, the rotation of the wire bolt will cause the sliding rod to rotate, which in turn will cause the limiting rod to rotate synchronously. As the limiting rod rotates with the wire bolt, the outer wall of the limiting rod will move relative to the inner wall of the ratchet ring. After the device secures the wire, if the wire bolt loosens due to environmental or other factors, the limiting rod will be restricted by the ratchet ring, preventing the limiting rod from rotating due to the loosening of the wire bolt. This reduces the probability of the wire bolt loosening and enhances the wire clamp's restrictive effect on the wire. Preferably, the auxiliary component includes a connecting plate fixedly connected to the outer wall of the fixed plate, two fixed rods rotatably connected to the outer wall of the connecting plate, two rotating rods rotatably connected to the outer walls of the two fixed rods, and two semi-circular plates rotatably connected to the inner walls of the two rotating rods.
[0013] When the lead-fixing terminal interacts with the lead-fixing slot to fix the lead, the lead-fixing slot contacts the internal conductor of the lead. The semi-circular plate near the lead-fixing slot moves downwards with the lead due to the force exerted by the lead-fixing terminal on the lead. Driven by this semi-circular plate, the rotating rod rotatably connected to the lead-fixing slot also moves, causing the two fixed rods connected to it to rotate around the rotatable connection point with the connecting plate. At this time, the rotating rod away from the lead-fixing slot will rotate around the two fixed rods... Driven by the movement, the semicircular plate moves in the opposite direction to the semicircular plate near the lead wire fixing groove, thereby causing the semicircular plate away from the lead wire fixing groove to move. At this time, the semicircular plate away from the lead wire fixing groove comes into contact with the insulation layer of the lead wire. Since the diameter of the insulation layer of the lead wire is larger than that of its internal conductor, the insulation layer of the lead wire is lifted. This allows the clamp to exert a lifting force on the unclamped part of the lead wire, reducing the probability of damage to the lead wire due to friction between the lead wire and the clamp caused by environmental or other factors, thereby reducing the probability of safety accidents. Preferably, the anti-slip component includes a wire fixing groove formed on the inner wall of the fixing plate, and a plurality of wire grooves are formed on the inner wall of the wire fixing groove, and a plurality of limiting balls are fixedly connected to the inner wall of the plurality of wire grooves.
[0014] After the wire clamp device secures the wire, the several wire slots in the wire fixing groove will fit against the wire. This will cause the several limiting balls on the inner wall of the wire slot to fit tightly against the wire. Since the wire is made of multiple thin wires twisted together, and the wire will bend under its own weight, the wire clamp will exert a pulling force on the clamp after installation. This will cause the clamp to generate a radial force along the direction of the wire. When the force exerted by the clamp on the wire is insufficient, the clamp may slide along the direction of the wire, causing the connection position to change. At this time, the wire will be stuck in the inner wall of the wire slot, and due to the restriction of the limiting balls, part of the radial force on the clamp can be offset, thereby reducing the possibility of the clamp sliding.
[0015] The present invention has the following beneficial effects: (1) To solve the problem of poor contact between the wire clamp and the wire caused by different wire specifications, resulting in increased contact resistance and local overheating at the contact point, this invention provides a wire clamping mechanism. After the lead wire is fixed, the worker uses a special gun to fix the gun and the fixing ring together. Then, the entire wire clamp device is lifted to the position of the wire to be connected, and the wire clamp device is hung on the wire. At this time, the worker can rotate the gun to turn the fixing ring, so that the fixing ring drives the wire bolt to rotate, and then the wire bolt drives the adapter ring to move towards the anti-slip component. The movement of the adapter ring will also drive the support plate to move synchronously. When it moves to a certain position, the rotating plate connected to the support plate... The chain plates connected to the rotating plate will restrict the wire to the outer wall of the anti-slip component. During the process of several chain plates contacting the wire and fixing the wire, the chain plates will be pressed against the outer wall of the wire by the action of the rotating plates on both sides. The telescopic rods set on the inner wall of the rotating plate will exert force on the rotating plates on both sides, thus making the chain plates press tightly against the outer wall of the wire. Due to the characteristics of the chain plates, the chain plates can change with the shape of the outer wall of the wire, which increases the contact area between the wire clamp device and the wire. This reduces the probability of problems such as local overheating caused by the wire not being tightly pressed against the wire clamp, and reduces the probability of wire clamp and wire failure. (2) In order to solve the problem that the wire clamp may loosen due to the weakening of the wire clamp's restrictive effect on the wire when it is fixed for a long time due to environmental factors, the present invention provides a stabilizing mechanism. When the wire clamp device completes the fixing of the wire, the rotation of the wire bolt will drive the sliding rod to rotate together, and then drive the limiting rod to rotate synchronously. When the limiting rod rotates with the wire bolt, the outer wall of the limiting rod will move relative to the inner wall of the ratchet ring. When the device completes the fixing of the wire, the wire bolt may loosen due to environmental or other factors. At this time, the limiting rod will be restricted by the ratchet ring, so that the limiting rod cannot be driven to rotate due to the loosening of the wire bolt. This can reduce the probability of the wire bolt loosening and enhance the wire clamp's restrictive effect on the wire. (3) To address the problem that wire clamps may rub against each other and damage the wires due to various factors during long-term use, this invention provides an auxiliary component. When the wire fixing terminal interacts with the wire fixing groove to fix the wire, the wire fixing groove contacts the internal conductor of the wire. The semicircular plate near the wire fixing groove will move downwards with the wire due to the force exerted by the wire fixing terminal on the wire. Driven by the semicircular plate near the wire fixing groove, the rotating rod rotatably connected to the wire fixing groove will also move, thereby driving the two fixed rods connected to it to rotate around the connecting plate. When the rotating connection rotates, the rotating rod away from the lead wire fixing groove will move in the opposite direction to the semicircular plate near the lead wire fixing groove under the action of the two fixed rods. This will cause the semicircular plate away from the lead wire fixing groove to move. At this time, the semicircular plate away from the lead wire fixing groove will contact the insulation layer of the lead wire. The diameter of the insulation layer of the lead wire is larger than that of the conductor part inside it, which will cause the insulation layer of the lead wire to be raised. This will allow the clamp to have a lifting force on the unclamped part of the lead wire, reducing the probability of damage to the lead wire due to friction between the lead wire and the clamp caused by environmental or other factors, thereby reducing the probability of safety accidents. (4) In order to solve the problem that the wire may bend due to its own weight and that the clamp may slide along the wire due to the influence of the lead wire, the present invention provides an anti-slip component. After the clamp device finishes fixing the wire, the several wire grooves opened at the wire fixing groove will fit together with the wire, and the several limiting balls on the inner wall of the wire groove will fit tightly with the wire. Since the wire is made of multiple thin wires twisted together, and the wire will bend due to its own weight, and after the clamp is installed, the fixed lead wire will have a pulling force on the clamp, which will generate a radial force along the direction of the wire. When the force of the clamp on the wire is insufficient, the clamp may slide along the direction of the wire, which will cause the connection position to change. At this time, the wire will be stuck on the inner wall of the wire groove, and due to the limitation of the limiting balls, part of the radial force on the clamp can be offset, thereby reducing the possibility of the clamp sliding.

Detailed Implementation
[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1, please refer to Figure 1 - Figure 10 This invention relates to a wire clamp device for live-line operation in power distribution engineering, comprising a fixing plate 13, a lead wire support plate 14 fixedly connected to the outer wall of the fixing plate 13, and a conductor support plate 15 fixedly connected to the outer wall of the fixing plate 13, and further comprising: The wire clamping mechanism 1 is engaged with the inner wall of the wire support plate 15 at its outer wall, and is used to clamp the wire. Stabilizing mechanism 2 is fixedly connected to the outer wall of the conductor support plate 15 at its outer wall. Stabilizing mechanism 2 is used to stabilize and clamp the conductor. The fixing mechanism 3 is fixedly connected to the outer wall of the fixing plate 13 at its outer wall. The fixing mechanism 3 is used to assist in clamping the lead wire. A wire bolt 111 is engaged with the inner wall of the wire support plate 15, a fixing ring 112 is fixedly connected to the outer wall of the wire bolt 111, and an adapter ring 113 is rotatably connected to the end of the wire bolt 111 away from the fixing ring 112.
[0021] After the lead wire is fixed, the staff uses a special gun to fix the gun and the fixing ring 112 together. Then, the entire wire clamp device is lifted to the position of the wire to be connected, and then the wire clamp device is hung on the wire. At this time, the staff can rotate the gun to turn the fixing ring 112, so that the fixing ring 112 drives the wire bolt 111 to rotate, and then the wire bolt 111 drives the adapter ring 113 to move towards the anti-slip component 32. The wire clamping mechanism 1 includes: The outer wall of the wire clamping assembly 11 is fixedly connected to the outer wall of the adapter ring 113; The outer wall of the contact component 12 is fixedly connected to the inner wall of the wire clamping component 11.
[0022] Stabilizing agency 2 includes: Sliding component 21, the outer wall of sliding component 21 is fixedly connected to the outer wall of wire support plate 15; The outer wall of the limiting component 22 is slidably connected to the inner wall of the sliding component 21.
[0023] Fixed mechanism 3 includes: Auxiliary component 31 is fixedly connected to the outer wall of fixed plate 13 via a connector. The connector includes a lead bolt 311 that engages with the inner wall of the lead support plate 14, a lead fixing terminal 312 that is rotatably connected to the outer wall of the lead bolt 311, and a lead fixing groove 313 that is provided on the outer wall of the fixing plate 13. In use, first place the lead wire to be connected to the power supply into the lead wire fixing groove 313, then tighten the lead wire bolt 311 so that the lead wire bolt 311 moves toward the lead wire fixing groove 313. Then the lead wire bolt 311 drives the lead wire fixing terminal 312 to move toward the lead wire fixing groove 313. When the outer wall of the lead wire fixing terminal 312 contacts the lead wire to be connected to the power supply, continue to tighten the lead wire bolt 311 so that the lead wire fixing terminal 312 interacts with the lead wire fixing groove 313, thereby fixing the lead wire to be connected to the power supply. Example 2, please refer to Figure 2 - Figure 13 The present invention is a clamp device for live-line construction in power distribution engineering. Based on Example 1, the anti-slip component 32 is fixedly connected to the inner wall of the fixing plate 13 at its outer wall.
[0024] The wire clamping assembly 11 includes a support plate 114 fixedly connected to the outer wall of the adapter ring 113. Two rotating plates 115 are rotatably connected to the outer wall of the support plate 114. Several chain plates 116 are rotatably connected to the outer walls of the two rotating plates 115. The chain plates 116 are rotatably connected to each other end to end.
[0025] The movement of the adapter ring 113 will also drive the support plate 114 to move synchronously. When it moves to a certain position, the rotating plate 115 connected to the support plate 114 and the chain plate 116 connected to the rotating plate 115 will restrict the wire to the outer wall of the anti-slip component 32. During the process of several chain plates 116 contacting the wire to fix the wire, the several chain plates 116 will be in contact with the outer wall of the wire under the action of the rotating plates 115 on both sides. The several telescopic rods 122 set on the inner wall of the rotating plate 115 will exert force on the rotating plates 115 on both sides, thereby making the chain plates 116 tightly in contact with the outer wall of the wire. Due to the characteristics of the chain plates 116, the several chain plates 116 can change with the shape of the outer wall of the wire, thereby increasing the contact area between the wire clamp device and the wire, thereby reducing the probability of problems such as local overheating caused by the wire not being tightly attached to the wire clamp, and reducing the probability of wire clamp and wire failure. The contact assembly 12 includes several fixing blocks 121 fixedly connected to the inner walls of the two rotating plates 115. The fixing blocks 121 are in pairs. A telescopic rod 122 is rotatably connected to the inner wall of the fixing blocks 121. Several fixing blocks 123 are rotatably connected to the outer wall of the end of the telescopic rod 122 away from the fixing blocks 121. The fixing blocks 123 are in pairs. Several fixed blocks 123 are fixedly connected to the support plate 114 at their outer walls.
[0026] The sliding assembly 21 includes a ratchet ring 211 fixedly connected to the outer wall of the wire support plate 15, a radial groove 212 on the inner wall of the wire bolt 111, and a longitudinal groove 213 on the inner wall of the wire bolt 111.
[0027] The limiting component 22 includes a slide rod 221 slidably connected to the inner wall of the longitudinal slide groove 213, a slide tube 222 fixedly connected to the outer wall of the slide rod 221, a spring 223 fixedly connected to the inner wall of the slide tube 222, and a limiting rod 224 fixedly connected to the outer wall of the spring 223.
[0028] When the wire clamp device finishes fixing the wire, the rotation of the wire bolt 111 will cause the slide bar 221 to rotate together, which in turn will cause the limiting bar 224 to rotate synchronously. When the limiting bar 224 rotates with the wire bolt 111, the outer wall of the limiting bar 224 will move relative to the inner wall of the ratchet ring 211. After the device finishes fixing the wire, the wire bolt 111 may loosen due to environmental or other factors. At this time, the limiting bar 224 will be restricted by the ratchet ring 211, so that the limiting bar 224 cannot be rotated due to the loosening of the wire bolt 111. This can reduce the probability of the wire bolt 111 loosening and enhance the limiting effect of the wire clamp on the wire. The auxiliary component 31 includes a connecting plate 314 fixedly connected to the outer wall of the fixed plate 13. Two fixed rods 315 are rotatably connected to the outer wall of the connecting plate 314. Two rotating rods 316 are rotatably connected to the outer walls of the two fixed rods 315. Two semi-circular plates 317 are rotatably connected to the inner walls of the two rotating rods 316.
[0029] When the lead wire fixing terminal 312 and the lead wire fixing groove 313 interact to fix the lead wire, the lead wire fixing groove 313 contacts the internal conductor portion of the lead wire. The semi-circular plate 317 near the lead wire fixing groove 313 will move downwards with the lead wire due to the force exerted by the lead wire fixing terminal 312 on the lead wire. Driven by the semi-circular plate 317 near the lead wire fixing groove 313, the rotating rod 316, which is rotatably connected to the lead wire fixing groove 313, will also move. This, in turn, will cause the two fixed rods 315 connected to it to rotate around the rotatable connection point with the connecting plate 314. At this time, the rotating rods 316 away from the lead wire fixing groove 313... Driven by the two fixed rods 315, the moving rod 316 moves in the opposite direction to the semicircular plate 317 near the lead wire fixing groove 313, thereby moving the semicircular plate 317 away from the lead wire fixing groove 313. At this time, the semicircular plate 317 away from the lead wire fixing groove 313 comes into contact with the insulation layer of the lead wire. The diameter of the insulation layer of the lead wire is larger than that of the conductor part inside it, which causes the insulation layer of the lead wire to be raised. This allows the wire clamp to have a lifting force on the unclamped part of the lead wire, reducing the probability of damage to the lead wire due to friction between the lead wire and the wire clamp caused by environmental or other factors, thereby reducing the probability of safety accidents. The anti-slip component 32 includes a wire fixing groove 321 formed on the inner wall of the fixing plate 13. A plurality of wire grooves 322 are formed on the inner wall of the wire fixing groove 321, and a plurality of limiting balls 323 are fixedly connected to the inner wall of the plurality of wire grooves 322.
[0030] After the wire clamp device has fixed the wire, the several wire grooves 322 opened at the wire fixing groove 321 will fit together with the wire, and the several limiting balls 323 on the inner wall of the wire groove 322 will fit tightly with the wire. Since the wire is made of multiple thin wires twisted together, and the wire will bend under its own weight, after the wire clamp is installed, the fixed lead wire will exert a tension on the wire clamp, which will generate a radial force along the direction of the wire. When the force of the wire clamp on the wire is insufficient, the wire clamp may slide along the direction of the wire, which will cause the connection position to change. At this time, the wire will be stuck in the inner wall of the wire groove 322, and due to the restriction of the limiting balls 323, part of the radial force on the wire clamp can be offset, thereby reducing the possibility of the wire clamp sliding.
[0031] One specific application of this embodiment is as follows: In use, the lead wire to be connected to power is first placed in the lead wire fixing groove 313, and then the lead wire bolt 311 is tightened so that the lead wire bolt 311 moves toward the lead wire fixing groove 313. Then the lead wire bolt 311 drives the lead wire fixing terminal 312 to move toward the lead wire fixing groove 313. When the outer wall of the lead wire fixing terminal 312 contacts the lead wire to be connected to power, the lead wire bolt 311 is tightened again so that the lead wire fixing terminal 312 interacts with the lead wire fixing groove 313, thereby fixing the lead wire to be connected to power. When the lead wire fixing terminal 312 and the lead wire fixing groove 313 interact to fix the lead wire, the lead wire fixing groove 313 contacts the internal conductor portion of the lead wire. The semi-circular plate 317 near the lead wire fixing groove 313 will move downwards due to the force exerted by the lead wire fixing terminal 312 on the lead wire. Driven by the semi-circular plate 317 near the lead wire fixing groove 313, the rotating rod 316, which is rotatably connected to the lead wire fixing groove 313, will also move. This, in turn, will cause the two fixed rods 315 connected to it to rotate around the rotatable connection point with the connecting plate 314. At this time, the rods away from the lead wire fixing groove 313... Driven by the two fixed rods 315, the rotating rod 316 moves in the opposite direction to the semicircular plate 317 near the lead wire fixing groove 313, thereby moving the semicircular plate 317 away from the lead wire fixing groove 313. At this time, the semicircular plate 317 away from the lead wire fixing groove 313 comes into contact with the insulation layer of the lead wire. The diameter of the insulation layer of the lead wire is larger than that of the conductor part inside it, which causes the insulation layer of the lead wire to be raised. This allows the wire clamp to have a lifting force on the unclamped part of the lead wire, reducing the probability of damage to the lead wire due to friction between the lead wire and the wire clamp caused by environmental or other factors, thereby reducing the probability of safety accidents. After the lead wire is fixed, the worker uses a special gun to fix the gun and the fixing ring 112 together. Then, the entire wire clamp device is lifted to the position of the connected wire, and then the wire clamp device is hung on the wire. At this time, the worker can rotate the gun to turn the fixing ring 112, causing the fixing ring 112 to drive the wire bolt 111 to rotate. In turn, the wire bolt 111 drives the adapter ring 113 to move towards the anti-slip component 32. The movement of the adapter ring 113 also causes the support plate 114 to move synchronously. When it moves to a certain position, the rotating plate 115 connected to the support plate 114, and the chain plate 116 connected to the rotating plate 115, will restrict the wire to the outer wall of the anti-slip component 32. During the process of several chain plates 116 contacting the wire and fixing the wire, the chain plates 116 will be pressed against the outer wall of the wire by the action of the rotating plates 115 on both sides. The several telescopic rods 122 set on the inner wall of the rotating plates 115 will exert force on the rotating plates 115 on both sides, thereby making the chain plates 116 press tightly against the outer wall of the wire. Due to the characteristics of the chain plates 116, the chain plates 116 can change with the shape of the outer wall of the wire, thereby increasing the contact area between the wire clamp device and the wire. This can reduce the probability of problems such as local overheating caused by the wire not being tightly pressed against the wire clamp, and reduce the probability of the wire clamp and the wire failing. When the wire clamp device finishes fixing the wire, the rotation of the wire bolt 111 will cause the slide bar 221 to rotate together, which in turn will cause the limiting bar 224 to rotate synchronously. When the limiting bar 224 rotates with the wire bolt 111, the outer wall of the limiting bar 224 will move relative to the inner wall of the ratchet ring 211. After the device finishes fixing the wire, the wire bolt 111 may loosen due to environmental or other factors. At this time, the limiting bar 224 will be restricted by the ratchet ring 211, so that the limiting bar 224 cannot be rotated due to the loosening of the wire bolt 111. This can reduce the probability of the wire bolt 111 loosening and enhance the limiting effect of the wire clamp on the wire. After the wire clamp device has fixed the wire, the several wire grooves 322 opened at the wire fixing groove 321 will fit together with the wire, and the several limiting balls 323 on the inner wall of the wire groove 322 will fit tightly with the wire. Since the wire is made of multiple thin wires twisted together, and the wire will bend under its own weight, after the wire clamp is installed, the fixed lead wire will exert a tension on the wire clamp, which will generate a radial force along the direction of the wire. When the force of the wire clamp on the wire is insufficient, the wire clamp may slide along the direction of the wire, which will cause the connection position to change. At this time, the wire will be stuck in the inner wall of the wire groove 322, and due to the restriction of the limiting balls 323, part of the radial force on the wire clamp can be offset, thereby reducing the possibility of the wire clamp sliding.
