Description

Technical Field

[0001] This invention relates to the field of power fittings technology, specifically to a vibration-resistant wire clamp fitting device. Background Technology

[0002] In the construction of new energy power generation projects such as biomass energy, geothermal energy, and hydrogen energy, as well as supporting power transmission projects, wire clamps are core components for clamping, fixing, and maintaining the spacing of conductors. They directly affect the electrical safety and operational stability of the power transmission system. Specifically, wire clamp devices are mainly used in power transmission lines to clamp, fix, and limit the conductors, ensuring that multi-split conductors maintain the specified spacing and relative position, preventing conductors from colliding or whipping with each other under conditions such as wind vibration, while ensuring a reliable connection between the conductors and the clamps, thus ensuring the safe and stable operation of the power transmission line.

[0003] Currently, manual installation of fittings requires a person to hold a nut in one hand and a tool with a bolt in the other to tighten them. This results in deviations in the quality of manual tightening of the clamps. Furthermore, the lack of a fixed alignment position for the bolts and nuts during manual installation can easily cause scratches, chipping, or seizing of the threads, reducing connection reliability. After long-term operation, the fittings are prone to loosening and failure due to vibration, leading to poor stability of the installation.

[0004] Meanwhile, when manually installing the wire clamp onto the conductor, the operator must first hold the moving and fixed rings of the wire clamp to align them, and then insert the bolt smoothly and manually tighten it with the nut. This requires the operator to repeatedly align and adjust the bolt to ensure that the bolt can smoothly pass through the moving and fixed rings of the wire clamp, which greatly prolongs the installation time of a single set of hardware, resulting in low installation efficiency of the wire clamp of the hardware device and poor convenience of manual installation of the hardware device.

[0005] Furthermore, it is difficult to ensure that the wire clamp and the conductor are strictly coaxial when installing hardware manually. The wire clamp is prone to skew or tilting, resulting in uneven contact between the conductor and the wire clamp and excessive gaps in some areas. This can lead to corona discharge, increase line loss, accelerate the aging of the conductor and hardware, increase the pressure of later operation and maintenance of the line, and affect the long-term safe and stable operation of the power transmission system.

[0006] Moreover, when adjusting the working range of the wire clamps in multi-wire clamp fittings, the common practice is to adjust them manually one by one. Operators need to adjust and lock each wire clamp individually, which is cumbersome and time-consuming. Since the adjustment process relies on human experience, it is difficult to keep the adjustment range and positional accuracy of each wire clamp consistent, making the adjustment of the wire clamps in the fittings quite complicated.

A plurality of positioning blocks are connected to one side of the secondary wedge block, and a ball is installed at one end of the positioning block. The positioning block drives the secondary wedge block to move in the accommodating cavity.

[0013] Preferably, two protruding blocks are installed in the accommodating cavity. The secondary wedge block has a large-angle surface one and a small-angle surface one.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This application can automatically align the bolts and nuts during the installation and tightening of hardware through the alignment auxiliary mechanism, eliminating the need for manual alignment and manual handling of the nut and bolt. This reduces the labor intensity and solves the problem that currently, when installing hardware, manual handling of the nut and bolt tool is required, which leads to deviations in the quality of manual tightening of the clamp. This is beneficial to improving the stability of hardware installation. 2. This application, through the cooperation of the clamping ring plate and the cover plate, can align the moving ring and the fixed ring of the wire clamp when the wire clamp is installed on the outside of the conductor. This allows personnel to directly insert the bolt through the moving ring and the fixed ring of the wire clamp, which automatically completes the coaxial alignment and pre-positioning of the bolt and nut before tightening the bolt, eliminating the need for manual alignment. This solves the problem that when manually installing the wire clamp on the conductor, it is necessary to manually hold the moving ring and the fixed ring of the wire clamp to align them before inserting the bolt smoothly and then manually tightening it with the nut. This is beneficial to improving the installation efficiency of the wire clamp of the hardware device and ensuring the convenience of manual installation of the hardware device. 3. This application, through its calibration mechanism, can automatically calibrate the fittings with the conductors during installation, avoiding the corona discharge problem caused by the wire clamps not being coaxial with the conductors during manual installation. It solves the problem that it is difficult to ensure strict coaxiality between the wire clamps and conductors during manual installation, which can easily lead to wire clamp skew or tilting, resulting in uneven contact between the conductors and wire clamps, excessive local gaps, and thus corona discharge, increased line loss, and accelerated aging of the conductors and fittings. This helps to ensure uniform contact between the wire clamps and conductors, and fundamentally avoids the skew and tilting problems caused by manual installation. 4. This application allows personnel to easily adjust the working range of the fitting device through the synchronization mechanism, achieving the effect of simultaneous adjustment of multiple line clamps. This solves the problem that currently, when adjusting the working range of the line clamps of the fitting device, it is necessary to manually adjust each line clamp separately, which is cumbersome, inefficient, and difficult to ensure consistency. It helps to simplify the adjustment operation, allowing personnel to quickly complete the overall adjustment without adjusting each line clamp individually. Attached Figure Description

Detailed Implementation

[0019] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0020] Please see Figure 1 , Figure 2 An anti-vibration wire clamp fitting device includes a fitting frame 1 and several wire clamps 2 mounted on the fitting. A synchronizing mechanism 36 is installed in the fitting frame 1 and connected to the several wire clamps 2. Each wire clamp 2 includes a clamp base 3, a clamp stationary ring 4, and a clamp moving ring 5. During installation, the operator attaches the wire clamps 2 to several split conductors. Specifically, the operator operates the clamp moving ring 5 to separate it from the clamp stationary ring 4, allowing the wire clamps to be connected. The clamp is installed on the outside of the wire. Then, the moving ring 5 of the clamp is closed to form a closed loop with the fixed ring 4 of the clamp, thus completing the initial installation. Then, a person needs to use a bolt tightening tool to install the bolt into the moving ring 5 and the fixed ring 4 of the clamp, and then tighten the clamp 2 to cooperate with the wire. The fixed ring 4 of the clamp is installed in the clamp base 3. The moving ring 5 of the clamp is connected to the fixed ring 4 of the clamp. The clamp 2 is provided with an alignment auxiliary mechanism 6 and a correction mechanism 26. Please see Figure 3 , Figure 4 , Figure 5 The alignment auxiliary mechanism 6 includes an alignment ring 7. A groove is formed in the wire clamp fixing ring 4, and the alignment ring 7 is disposed within the groove. Several bayonets 8 are formed on the alignment ring 7. A protruding ring 9 is connected to one side of the alignment ring 7. Several sliding guide shafts 10 are provided in the wire clamp fixing ring 4. A guide plate 11 and a locking plate 13 are connected to one side of each sliding guide shaft 10. A threaded groove 12 is formed on one side of the guide plate 11, and the guide plate 11 is disposed outside the positioning ring. An arc-pressing plate 14 is connected to the locking plate 13, and the arc-pressing plate 14 is disposed outside the protruding ring 9. A connecting column 15 is connected to one side of the locking plate 13, and the connecting column 15 is connected to the sliding guide shaft 10 on one side of the guide plate 11. Before tightening the clamp 2, the operator can first install the nut in the clamp retaining ring 4. There is no need for the operator to manually tighten the nut and bolt. Specifically, the operator aligns the nut with the corner groove 20 and then pushes the nut into the clamp retaining ring 4. At this time, the nut will squeeze the alignment ring 7, causing the alignment ring 7 to squeeze the spring 16 to move in the ring groove. More specifically, because several guide plates 11 are distributed on the outside of the alignment ring 7, as the alignment ring 7 continues to move, the slot 8 on the alignment ring 7 will reach the guide plate 11. At this time, the guide plate 11 will move and spring into the slot 8 under the cooperation of the sliding guide shaft 10 and the spring 17, and pass through the alignment ring 7. It should be further explained that after several guide plates 11 pass through the aligning ring 7 through the bayonet 8, they will form a ring together. Because the inner side of the guide plate 11 has a threaded groove 12 that mates with the bolt, during the bolt installation process, this ring formed by several guide plates 11 will pre-mate with the bolt thread. Before the bolt is officially locked with the final nut, it can first perform axial positioning, radial guidance and circumferential anti-rotation of the bolt, so that the bolt maintains a stable posture and mates with the nut for installation. It is important to note that when the guide plate 11 passes through the alignment ring 7, the nut also moves into the locking plate 13. Specifically, the pressure plate 14 of the locking plate 13 is located outside the convex ring 9. When the nut moves the alignment ring 7 and the convex ring 9 on one side of the alignment ring 7, the convex ring 9 will separate from the pressure plate 14. At this time, the pressure plate 14 will be in close contact with the outside of the nut. Therefore, as the nut continues to be pushed in, the outside of the nut will also separate from the pressure plate 14. The locking plate 13 and the pressure plate 14 pop out under the cooperation of the sliding guide shaft 10 and the second spring 17, forming the locking plate 13 locking the outside of the nut and the pressure plate 14 limiting one side of the nut. It is important to note that when the guide plate 11 passes through the alignment ring 7, the bayonet 8 also loses its engagement with the guide plate 11. At this time, the alignment ring 7 will spring back under the restoring force of the spring 16. The springing force of the alignment ring 7 and the limiting force of the pressure plate 14 on the nut form a clamp, thereby achieving axial locking of the nut and radial locking of the nut by the locking plate 13, forming an all-round locking to ensure the nut is fixed, so that the bolt can be smoothly locked with the nut, and thus the moving ring 5 of the wire clamp and the fixed ring 4 of the wire clamp are locked. This eliminates the need for manual alignment and manual tightening of the nuts and bolts during the installation of the online clamp 2, thus reducing the intensity of manual labor. It also solves the problem that manual installation of hardware requires holding a nut in one hand and a tool with a bolt in the other to tighten the clamp, which leads to deviations in the quality of manual tightening of the clamp. This improves the stability of the hardware installation.

[0021] Several springs 16 are installed on one side of the alignment ring 7. The springs 16 are installed in the ring groove. The alignment ring 7 slides in the ring groove through the springs 16. A spring 2 17 is provided at one end of the sliding guide shaft 10. The sliding guide shaft 10 slides in the clamping ring 4 through the spring 2 17.

[0022] Please see Figure 6The wire clamp seat 3 is externally connected to a retaining ring plate 18, which is located outside the wire clamp fixed ring 4 and the wire clamp moving ring 5. The retaining ring plate 18 has an arc groove 19 and a corner groove 20. The corner groove 20 can position the nut at an angle, allowing the operator to directly push the nut into the alignment ring 7 after positioning it at the correct angle, thus tightening the nut. The corner groove 20 is located on one side of the alignment ring 7. The arc groove 19 has a cavity containing a cover plate 21 and several springs 22. One end of the cover plate 21 is connected to one of the springs. The spring 22 is connected to the cover plate 21, and a guide frame 23 is connected to one side of the cover plate 21. When the bolt is about to be installed in place, the nut of the bolt will reach the arc groove 19 and the cover plate 21. At this time, the person moves the guide frame 23, which causes the guide frame 23 to move the cover plate 21 to compress the spring 22, ensuring the normal movement of the bolt. As the bolt continues to move, the nut will enter the moving ring 5 of the wire clamp. At this time, the cover plate 21 will rise under the action of the restoring force of the spring 22, which will limit the bolt. The nut that mates with the bolt is limited by the arc plate 14. In this way, even if the bolts and nuts become loose due to problems after long-term operation, the bolts will not fall off directly because they are limited by the cover plate 21 and the nuts by the arc-pressing plate 14. This effectively avoids the risk of the line clamp 2 becoming loose and the conductor becoming unstable due to the fasteners completely coming off. It ensures that the fitting device can still maintain the basic clamping function and structural integrity of the line clamp 2 even when the fasteners fail. This significantly improves the operational reliability and safety redundancy of the fitting device, reduces the probability of sudden line failures, reduces the frequency of high-altitude emergency repairs and maintenance, and ensures the continuous and stable operation of the transmission line.

[0023] The clamp seat 3 has a movable groove. A guide block 24 is connected to one side of the clamp fixed ring 4. The guide block 24 is connected to the movable groove. A locking screw 25 is threaded onto the clamp seat 3. The locking screw 25 passes through the guide block 24. In the initial state, the clamp moving ring 5 and the clamp fixed ring 4 are closed together by the restraint of the clamping ring plate 18. When the operator installs the clamp head 2 onto the conductor, the locking screw 25 needs to be turned out a certain length so that the guide block 24 of the clamp fixed ring 4 can move in the clamp seat 3. At this time, the operator manually pulls out the clamp head 2. The clamp moving ring 5 and the clamp fixed ring 4 will cross the restraint of the clamping ring plate 18. Then the clamp moving ring 5 and the clamp fixed ring 4 can be separated so that the clamp head 2 can be installed on the conductor. It should be noted that after installation, the moving ring 5 and the fixed ring 4 of the wire clamp need to be closed together to position the wire. Then, the personnel move the hardware frame 1 towards the wire clamp head 2 and the wire so that the clamping ring plate 18 on the wire clamp seat 3 can reposition the moving ring 5 and the fixed ring 4 of the wire clamp, and then retighten the locking screw 25 so that the locking screw 25 locks the guide block 24 of the fixed ring 4 of the wire clamp. At this time, the moving ring 5 and the fixed ring 4 of the wire clamp are automatically closed by the constraint of the clamping plate 18. There is no need for the operator to continuously hold the moving ring 5 and the fixed ring 4 of the wire clamp. Then, the operator can first install the nut into the fixed ring 4 of the wire clamp, and then use the tool that drives the bolt to directly pass the bolt through the moving ring 5 and the fixed ring 4 of the wire clamp and cooperate with the nut to tighten the wire clamp 2. The whole installation process is orderly and smooth. There is no need for the operator to perform multiple complex operations at the same time. It avoids the chaotic situation where the operator has to manually hold the wire clamp 2, insert the installation bolt, and hold the nut to cooperate with the bolt. It eliminates the inconvenience of multi-tasking. It achieves the effect of automatically completing the coaxial alignment and pre-positioning of the bolt and nut before the bolt is tightened, eliminating the need for continuous manual alignment. This solves the problem that when manually installing the wire clamp 2 on the conductor, it is necessary to manually hold the moving ring 5 and the fixed ring 4 of the wire clamp to align them before inserting the bolt smoothly and then manually tightening it with the nut. This helps to improve the installation efficiency of the wire clamp 2 of the hardware device and ensures the convenience of manual installation of the hardware device.

[0024] Please see Figure 7 , Figure 8 Both the fixed ring 4 and the moving ring 5 of the wire clamp have accommodating cavities. The correction mechanism 26 includes a secondary wedge 29, which is disposed in the accommodating cavity. Several positioning blocks 28 are connected to one side of the secondary wedge 29. A ball 27 is installed at one end of the positioning block 28 and rolls at one end of the positioning block 28 to ensure that the wire can move normally in the wire clamp 2. The positioning block 28 drives the secondary wedge 29 to move in the accommodating cavity. When the wire clamp 2 is installed to position the wire, the wire clamp 2 will pre-position the wire. At this time, the wire will squeeze the ball 27, causing the ball 27 to drive the positioning block 28 to move. When the positioning block 28 moves, it will also drive the secondary wedge 29. As block 29 moves within the accommodating cavity, during the driving movement of the secondary wedge block 29, the large-angle surface 30 on it and the large-angle surface 33 on the corresponding protruding block 32 fit together and form an inclined transmission engagement. Under the pushing action of the secondary wedge block 29, the large-angle surface 30 and the large-angle surface 33 achieve force transmission and motion direction conversion through inclined extrusion, driving the protruding block 32 to move smoothly outward radially, thereby achieving rapid transmission output in the initial stage and laying the foundation for the subsequent relay transmission of the small-angle surface. At the same time, the protruding block 32 will drive the V-shaped block 35 to move outward, which also ensures that the wire clamp 2 and the wire are coaxial in advance, providing a foundation for coaxiality during subsequent locking. It should be further explained that as the bolts and nuts are tightened and locked onto the wire clamp 2, the squeezing effect of the wire on the ball 27 continues to increase and gradually pushes the ball 27 to move inward, thereby driving the secondary wedge block 29 to continue its axial feeding motion. During this process, the small inclined surface 31 on the secondary wedge block 29 and the small inclined surface 34 on the extension block 32 fit together to form a relay-type inclined surface transmission. Under the action of the small inclined surface transmission pair, the extension block 32 and the V-shaped plate 35 continue to be driven to complete the subsequent displacement, ensuring that the wire clamp 2 and the wire always maintain a coaxial fit, avoiding problems such as skewing and warping. It is particularly important to note that the above-mentioned two-stage transmission can achieve a larger V-plate 35 correction stroke while ensuring a smaller movement distance of the second-stage wedge. This results in a shorter overall stroke and a more compact structure. Furthermore, the two-stage tilt angle relay transmission allows the larger tilt angle to handle the initial movement, enabling a smooth start and rapid positioning, allowing the V-plate 35 to quickly enter the predetermined position and avoiding slow initial correction. The smaller tilt angle handles the later movement, continuing to amplify the displacement during the tightening of bolts and nuts, achieving more thorough and precise coaxial correction, and ensuring that the final posture is completely upright. This solves the problems of difficult start-up and slow movement, while ensuring high final positioning accuracy and thorough correction.

[0025] Two protruding blocks 32 are installed in the accommodating cavity. The secondary wedge block 29 has a large tilt angle surface 30 and a small tilt angle surface 31. The protruding blocks 32 have a large tilt angle surface 33 and a small tilt angle surface 34. The large tilt angle surface 30 and the large tilt angle surface 33 are in contact, and the small tilt angle surface 31 and the small tilt angle surface 34 are in contact.

[0026] A guide groove is provided in the accommodating cavity, and the protruding block 32 is connected to the guide groove. The movement of the secondary wedge block 29 drives the protruding block 32 to move outward. One end of the protruding block 32 is connected to a V-shaped plate 35. The V-shaped plate 35 positions the wire. The V-shaped structure of the V-shaped plate 35 naturally has an automatic centering function. No matter whether the initial position of the wire is too high, too low, too left, or too right, it will be forcibly guided to the center position by the inclined surface of the V-shaped plate 35. The more fully and symmetrically the V-shaped plate 35 moves outward within a suitable range, the stronger the effect of pushing the wire towards the center. Ultimately, the wire will be stably constrained online. The geometric center of the clamp is precisely coaxial with the wire clamp 2, ensuring the accuracy of the hardware installation. This avoids the corona discharge problem that occurs when the wire clamp 2 is not coaxial with the conductor during manual installation. It solves the problem that it is difficult to ensure that the wire clamp 2 is precisely coaxial with the conductor during manual installation, which can easily lead to wire clamp skewing or tilting, resulting in uneven contact between the conductor and the wire clamp, excessive local gaps, and thus corona discharge, increased line loss, and accelerated aging of the conductor and hardware. This helps to ensure that the wire clamp and the conductor are evenly contacted, and avoids the skewing and tilting problems caused by manual installation from the root.

[0027] Please see Figure 9 , Figure 10 The wire clamp seat 3 is connected to a positioning pin 37 on one side. The synchronization mechanism 36 includes several synchronization frames 38. The synchronization frames 38 are provided with adjustment slots 39. The positioning pin 37 is installed through the four adjustment slots 39. The synchronization frame 38 is connected to a guide post 40. The hardware frame 1 is connected to several guide frames 41. The guide post 40 is installed in the guide frame 41. When it is necessary to adjust the working range of the wire clamp 2, the operator loosens the fastener of the wire clamp 2. Then, the operator only needs to adjust the two symmetrical wire clamps 2 at the same time, so that the wire clamp seat 3 drives its positioning pin 37 to move. At this time, the positioning pin 37 will move in the four adjustment slots 39 on its outside, so that the synchronization frame 38 moves synchronously, thereby completing the synchronous adjustment of all wire clamps 2. It is particularly important to note that when the synchronizing frame 38 moves, it moves in the direction guided by the guide column 40 and the guide frame 41. Therefore, when the wire clamps 2 are adjusting their working range, the synchronizing frame 38 can move in an orderly manner, thereby achieving synchronous adjustment of all wire clamps 2. This solves the problem that when adjusting the working range of the wire clamps 2 of the fitting device, it is necessary to manually adjust each wire clamp 2 separately, which is cumbersome, inefficient, and difficult to ensure consistency. It helps to simplify the adjustment operation, allowing personnel to quickly complete the overall adjustment without adjusting each wire clamp individually.

[0028] When using this invention: First, during the installation of the hardware, personnel install several wire clamps 2 onto several split conductors. Specifically, personnel operate the moving ring 5 of the wire clamp to separate it from the fixed ring 4 of the wire clamp. Then, the wire clamp can be installed on the outside of the conductor. Subsequently, the moving ring 5 of the wire clamp is closed to form a closure with the fixed ring 4 of the wire clamp, thus completing the initial installation. Then, personnel need to use a bolt tightening tool to install bolts into the moving ring 5 and the fixed ring 4 of the wire clamp, thereby tightening the wire clamp 2 to cooperate with the conductor. Secondly, in the initial state, the moving ring 5 and the fixed ring 4 of the wire clamp are closed together by the restraint plate 18. When the operator installs the wire clamp 2 onto the conductor, the locking screw 25 needs to be turned a certain length so that the guide block 24 of the fixed ring 4 can move in the wire clamp seat 3. At this time, the operator manually pulls out the wire clamp 2, and the moving ring 5 and the fixed ring 4 will cross the restraint of the restraint plate 18. Then, the moving ring 5 and the fixed ring 4 can be separated so that the wire clamp 2 can be installed on the conductor. After installation, the moving ring 5 and the fixed ring 4 need to be closed together to position the conductor. Then, the operator moves the hardware frame 1 towards the wire clamp 2 and the conductor so that the restraint plate 18 on the wire clamp seat 3 re-aligns the moving ring 5 and the fixed ring 4. The clamping ring 4 is limited, and the locking screw 25 is retightened, so that the locking screw 25 locks the guide block 24 of the clamping ring 4. At this time, the clamping ring 5 and the clamping ring 4 are automatically closed by the constraint of the clamping ring plate 18. There is no need for the operator to continuously hold the clamping ring 5 and the clamping ring 4. Then, the operator can first install the nut into the clamping ring 4, and then use the tool that drives the bolt to directly pass the bolt through the clamping ring 5 and the clamping ring 4 and the nut to tighten the clamp head 2. The whole installation process is orderly and smooth. There is no need for the operator to perform multiple complex operations at the same time. It avoids the chaotic situation where the operator has to manually hold the clamp head 2, insert the installation bolt, and hold the nut to cooperate with the bolt. It eliminates the inconvenience of multi-tasking. Then, before tightening the clamp 2, the operator can first install the nut in the clamp retaining ring 4, without manually tightening the nut and bolt. Specifically, the operator aligns the nut with the corner groove 20 and then pushes the nut into the clamp retaining ring 4. At this time, the nut will squeeze the alignment ring 7, causing the alignment ring 7 to squeeze the spring 16 and move in the ring groove. More specifically, because several guide plates 11 are distributed on the outside of the alignment ring 7, as the alignment ring 7 continues to move, the retaining groove 8 on the alignment ring 7 will reach the guide plate 11. At this time, the guide plate 11 slides the guide shaft 10. With the cooperation of spring 17, it will move and spring into the bayonet 8 and pass through the alignment ring 7. It should be added that after several guide plates 11 pass through the alignment ring 7 from the bayonet 8, they will form a ring together. Because the inner side of the guide plate 11 has a threaded groove 12 that mates with the bolt, during the bolt installation process, this ring formed by several guide plates 11 will pre-mate with the bolt thread. Before the bolt is officially locked with the nut, it can first perform axial positioning, radial guidance and circumferential anti-rotation of the bolt, so that the bolt maintains a stable posture and mates with the nut for installation. Furthermore, when the guide plate 11 penetrates the alignment ring 7, the nut also moves into the locking plate 13. Specifically, the pressure plate 14 of the locking plate 13 is located outside the convex ring 9. When the nut moves the alignment ring 7 and the convex ring 9 on one side of the alignment ring 7, the convex ring 9 will separate from the pressure plate 14. At this time, the pressure plate 14 will be in close contact with the outside of the nut. Therefore, as the nut continues to be pushed in, the outside of the nut will also separate from the pressure plate 14. The locking plate 13 and the pressure plate 14 will pop out under the cooperation of the sliding guide shaft 10 and the second spring 17, forming the locking plate 13 locking the outside of the nut. The pressure plate 14 limits one side of the nut. It is important to note that when the guide plate 11 passes through the alignment ring 7, the clamp 8 also loses its engagement with the guide plate 11. At this time, the alignment ring 7 will spring back under the restoring force of the spring 16. The springing force of the alignment ring 7 and the limiting force of the pressure plate 14 on the nut form a clamp, thereby achieving axial locking of the nut and radial locking of the nut by the locking plate 13, forming an all-round locking to ensure the nut is fixed, so that the bolt can be smoothly locked with the nut, and thus the moving ring 5 of the wire clamp and the fixed ring 4 of the wire clamp are locked. In addition, when the wire clamp 2 is installed to position the wire, the wire clamp 2 will first pre-position the wire. At this time, the wire will squeeze the ball 27, causing the ball 27 to drive the positioning block 28 to move. When the positioning block 28 moves, it will also drive the secondary wedge block 29 to move in the accommodating cavity. During the driving movement, the large angle surface 30 on the secondary wedge block 29 and the large angle surface 33 on the corresponding protruding block 32 fit together and form a slope transmission cooperation. Under the pushing action of the secondary wedge block 29, the large angle surface 30 and the large angle surface 33 achieve force transmission and motion direction conversion through slope compression, driving the protruding block 32 to move smoothly outward radially, thereby realizing the rapid transmission output in the initial stage and laying the foundation for the subsequent relay transmission of the small angle surface. Simultaneously, the extension block 32 will drive the V-shaped block 35 to move outward, which also ensures that the wire clamp 2 and the wire are coaxial, providing a foundation for coaxiality during subsequent locking. It should be added that as the bolts and nuts continuously tighten the wire clamp 2, the squeezing effect of the wire on the ball 27 continues to increase and gradually pushes the ball 27 to move inward, thereby driving the secondary wedge block 29 to continue to feed along the axial direction. During this process, the small inclined surface 31 on the secondary wedge block 29 and the small inclined surface 34 on the extension block 32 fit together to form a relay-type inclined surface transmission. Under the action of the small inclined transmission pair, the extension block 32 and the V-shaped plate 35 continue to drive to complete the subsequent displacement, ensuring that the wire clamp 2 and the wire always maintain a coaxial fit, avoiding problems such as skewing and warping. Finally, when it is necessary to adjust the working range of the wire clamp 2, the operator loosens the fasteners of the wire clamp 2. Then, the operator only needs to adjust the two symmetrical wire clamps 2 at the same time, so that the wire clamp seat 3 moves its positioning pin 37. At this time, the positioning pin 37 will move in the four adjustment slots 39 on its outside, so that the adjustment frame 38 moves synchronously, thereby completing the synchronous adjustment of all wire clamps 2. When the adjustment frame 38 moves, it will move in the direction of the guide frame 41 under the action of the guide column 40. Therefore, when the working range of the wire clamps 2 is adjusted, the adjustment frame 38 can move in an orderly manner, thereby realizing the synchronous adjustment of all wire clamps 2.
