Description

Technical Field

[0001] This invention belongs to the field of cable supports, specifically relating to a cable support for electrical construction. Background Technology

[0002] Existing cable supports for electrical construction are mostly fixed structures with non-adjustable placement plate heights. Cable laying requires workers to go down into the trench, resulting in limited operating space and poor safety. Although some supports can be raised and lowered, they cannot raise the placement plate above the ground. Cables can only be laid and combed in the trench, which is prone to dragging, twisting, and damage to the outer sheath. Furthermore, it is difficult to arrange multiple cables, resulting in low installation efficiency and poor forming quality, making it difficult to meet the needs of efficient, safe, and standardized on-site construction.

[0003] Patent CN108695789B discloses a cable support and a cable support device inside an offshore wind turbine tower. The device includes: a guide rail for providing a sliding path; two vertical arms connected perpendicularly to the guide rail and sliding along the sliding path; and a cross brace fixedly connected at both ends to the two vertical arms. The provided cable support system includes: a tower; and multiple cable supports as described above. The guide rails of the multiple cable supports are sequentially fixed inside the tower. The cable support provided by this patent is adjustable in both horizontal and vertical directions, making the support suitable for various laying occasions, with low requirements for support design and installation, and can effectively cope with changes in cable path.

[0004] However, during the use of the above-mentioned device, it is difficult to simultaneously and quickly bind and fix the placed cable while adjusting the horizontal and vertical directions of a part of the bracket. This can easily cause the cable to vibrate during the installation angle adjustment, which in turn causes the cable to shake and twist during installation, affecting the installation efficiency and accuracy of the device. Summary of the Invention

[0005] The purpose of this invention is to provide a cable bracket for electrical construction, so as to solve the problem that it is difficult to adjust the vertical movement of the cable support plate and the bending of the cable during the cable installation process.

[0006] To achieve the above objectives, the present invention provides a cable support for electrical construction, comprising: a support column, a horizontal support arm mounted on the support column, a vertical support arm mounted on the horizontal support arm, an electrically operated telescopic rod provided on the support column, a fixed arc plate mounted on the vertical support arm, a limiting mechanism for cable positioning provided on the inner wall of the support column, an adjustment mechanism for cable adjustment provided on the upper inner wall of the fixed arc plate, a connecting plate fixedly connected to the telescopic end of the electrically operated telescopic rod passing through the horizontal support arm, a placement arc plate provided on the connecting plate, and a flexible rolling element installed on the inner wall of the placement arc plate. The wheel has a fixed groove block fixedly connected to the top of the arc plate. The inner wall of the fixed groove block is rotatably connected to the mounting clamp. The circumferential surface of the mounting clamp is equipped with a mounting flange assembly. The inner wall of the support column is fixedly connected to a fixed column. The top of the fixed column is fixedly connected to a top plate. The support column is equipped with a guide slide rod. This eliminates the need to bend over, go down into the trench, or work in narrow spaces, making cable installation safer, more labor-saving, and significantly improving efficiency. It allows multiple cables to be neatly arranged above the ground at once and then lowered synchronously, resulting in a more orderly arrangement. It eliminates the need for repeated adjustments in the trench, and the installation is completed in one go.

[0007] In one possible implementation, the inner wall of the connecting plate is rotatably connected to a roller, which contacts a guide rail. The top plate is located on the movement trajectory of the mounting clamp and is used to push the mounting clamp to rotate in the opposite direction. The surface of the connecting plate has a through hole, and the fixing column passes through the through hole in the connecting plate. The diameter of the through hole is larger than the diameter of the fixing column, so the fixing column does not contact the connecting plate. The roller is used to reduce the wear of the connecting plate during movement, so that the mounting clamp is located above the arc plate and limits and wraps the cable, restricting the radial sway and twisting of the cable. This keeps the cable straight throughout the installation process, fundamentally avoiding twisting, knotting, and tangling, greatly reducing manual handling procedures, preventing the cable from arching upwards and coming off the supporting arc plate during the descent, and preventing the cable from swinging and twisting left and right during movement and descent. This ensures that the cable centerline coincides with the bracket installation reference, eliminating the need for manual support, correction, and alignment, and meeting the construction accuracy requirements in one go.

[0008] In one possible implementation, the number of flexible rolling rollers is set to multiple, and the multiple flexible rolling rollers are respectively arranged in an arc array on the inner wall of the arc plate. The cable is located inside the arc plate. At this time, the telescopic end of the electric telescopic rod will be reset and drive the connecting plate to move back and forth. During the back and forth movement, the connecting plate will synchronously drive the arc plate to move back and forth. The movement of the arc plate will drive the flexible rolling rollers to move.

[0009] In one possible implementation, the limiting mechanism includes a rubber block one, which is slidably mounted on the inner wall of the guide slide rod. A top rod is fixedly mounted on the inner wall of the rubber block one, and a rubber block two is fixedly connected to the lower inner wall of the top rod. An elastic telescopic sleeve is fixedly connected to the upper side of the horizontal support arm, and a support block is fixedly connected to the telescopic end of the elastic telescopic sleeve. A pressure-bearing arc block is fixedly connected to the circumferential surface of the mounting plate, so that the mounting arc plate is in a relatively suspended state and can move slightly downward through the elastic telescopic sleeve. At this time, a flexible buffer support can be formed to avoid the cable being rigidly squeezed, bumped, or crushed, and to provide a uniform, gentle, and controllable upward lifting force. The inner wall of the support column is fixedly connected to the elastic telescopic sleeve, so that the cable is not pressed hard on the structure, but is in an elastic lifting state, which can effectively eliminate vibration and impact during the installation process, protect the cable insulation layer from being crushed, deformed, or scratched, and improve the cable installation effect and quality of the device.

[0010] In one possible implementation, the limiting mechanism further includes a warning sleeve, which is fixedly connected to the circumferential surface of the fixed column. A sliding sleeve is slidably connected to the circumferential surface of the fixed column. An elastic telescopic rod is fixedly connected to the inner wall of the arc plate. A connecting plate two is fixedly connected to the telescopic end of the elastic telescopic rod. A contact block is fixedly connected to the inner wall of the connecting plate two through one end of a connecting rod. A movable rubber block is fixedly connected to the inner wall of the connecting plate two through the other end of the connecting rod. The circumferential surface of the fixed column contacts the inner wall of the elastic telescopic sleeve, allowing the warning sleeve to be fully exposed to the outside world. This allows workers to visually observe the state of the warning sleeve, enabling them to more intuitively and quickly understand whether the cable installation is bent, allowing the cable to be adjusted in a timely manner. This improves the installation efficiency of the device and makes the installation simple and clear.

[0011] In one possible implementation, the pressure-bearing arc block is located on the movement trajectory of the second rubber block, and the second rubber block is used to apply pressure to the pressure-bearing arc block to maintain stability. The support block is located on the movement trajectory of the first connecting plate, and the support block is used to provide buffer support for the first connecting plate. A return spring is provided between the sliding sleeve and the fixed column. The sliding sleeve consists of a ring, a connecting rod, and a sleeve. The sleeve is fitted around the circumference of the warning sleeve. The movement of the second connecting plate will cause the contact block to move, and the movement of the second connecting plate will also cause the moving rubber block to move. If the cable bends during the movement, the bent side of the cable will contact the contact block and squeeze the elastic telescopic rod through the contact block.

[0012] In one possible implementation, the adjustment mechanism includes a horizontal sliding groove rod slidably mounted on the upper inner wall of the fixed arc plate. A vertical sliding rod is slidably mounted on the inner wall of the horizontal sliding groove rod. A pressure arc plate is fixedly connected to the bottom of the vertical sliding rod. A pull rope is installed on the inner wall of the vertical sliding rod, and a reinforcing rib is fixedly connected to the inner wall of the vertical sliding rod. The vertical sliding rod will drive the reinforcing rib to move. During this movement, the pressure arc plate straightens a portion of the cable, improving the installation accuracy of the cable and ensuring the subsequent cable installation effect.

[0013] In one possible implementation, the adjustment mechanism further includes a first rust-proof sleeve, which is fixedly connected to the inner wall of the pressure arc block. A second rust-proof sleeve is slidably connected to the circumferential surface of the first rust-proof sleeve. The second rust-proof sleeve and the first rust-proof sleeve can isolate a portion of the locking flange to prevent rusting, thus avoiding jamming during subsequent cable disassembly and installation, and improving the efficiency and speed of cable installation by the device.

[0014] In one possible implementation, the second rust-proof sleeve contacts the pressure arc block, and the second rust-proof sleeve is used to protect the parts to be installed and connected. The pressure arc plate is located directly above the fixed arc plate. When the pressure arc block rotates, it will synchronously drive the first rust-proof sleeve to rotate synchronously. The first rust-proof sleeve will drive the second rust-proof sleeve to rotate. When the two pressure arc blocks are aligned and fit together, the cable installation is nearing completion. The staff needs to tighten the flanges of all relevant parts to strengthen the fixation.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This electrical construction cable support system, through the coordinated movement of the support columns, horizontal supports, vertical supports, electric telescopic rods, fixed arc plates, connecting plates, rollers, placement arc plates, flexible rolling rollers, fixed groove blocks, mounting clamps, mounting flange assemblies, fixed columns, top plates, and guide slide rods, ensures that the placement arc plate is positioned above the ground on both sides of the cable trench. At this point, the cable can be placed on the flexible rolling rollers on the inner arc surface of the placement arc plate. The flexible rolling rollers prevent wear and damage to the cable sheath, allowing the cable to be laid, arranged, and organized at ground level without needing to go down into the trench. Workers can lay cables while standing on flat ground, without bending over, going down into the trench, or working in confined spaces. This makes cable installation safer, less labor-intensive, and significantly improves efficiency. Multiple cables can be neatly arranged above the ground at once and then simultaneously lowered, resulting in a more orderly arrangement without repeated adjustments within the trench, achieving a one-time installation.

[0017] 2. This electrical construction cable support, through the coordinated movement of the vertical support arm, electric telescopic rod, fixed arc plate, connecting plate one, rollers, placement arc plate, fixed groove block, installation clamp, installation flange assembly, fixed column, top plate, and guide slide rod, ensures that the installation clamp is positioned above the placement arc plate and limits and wraps the cable, restricting radial swaying and twisting of the cable. This keeps the cable straight throughout the installation process, preventing twisting, knotting, and tangling at the source. It significantly reduces manual handling procedures, prevents the cable from arching upwards and detaching from the supporting arc plate during positioning and descent, and avoids lateral swaying and twisting of the cable during movement and descent. It ensures that the cable centerline coincides with the support installation benchmark, eliminating the need for manual support, correction, and alignment, and meeting construction accuracy requirements in one placement.

[0018] 3. This electrical construction cable support, through the coordinated movement of rubber block one, top rod, rubber block two, elastic telescopic sleeve, support block, pressure arc block, warning sleeve, sliding sleeve, elastic telescopic rod, connecting plate two, contact block, and moving rubber block, allows the placement arc plate to be in a relatively suspended state. It can move slightly downwards via the elastic telescopic sleeve, forming a flexible buffer support to prevent the cable from being rigidly squeezed, bumped, or damaged. It provides uniform, gentle, and controllable upward support, ensuring the cable is not rigidly pressed against the structure but is in an elastically supported state. This effectively eliminates vibration and impact during installation, protecting the cable insulation layer from being crushed, deformed, or scratched, thus improving the cable installation effect and quality. The warning sleeve is fully exposed to the outside, allowing workers to visually observe its condition and quickly and intuitively understand whether the cable is bent, enabling timely adjustment and improving installation efficiency, making the installation simple and clear.

[0019] 4. This electrical construction cable support, through the coordinated movement of horizontal sliding rods, vertical sliding rods, arc-pressing plates, pull ropes, reinforcing ribs, rust-proof sleeve one, and rust-proof sleeve two, causes the vertical sliding rods to move the reinforcing ribs. During the movement of the arc-pressing plates, a portion of the cable is straightened, improving the accuracy of cable installation and ensuring the subsequent cable installation effect. Rust-proof sleeve two and rust-proof sleeve one can isolate a portion of the locking flange to prevent rusting, avoiding jamming during subsequent cable disassembly and installation, and improving the efficiency and speed of cable installation by this device.

[0031] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0032] like Figures 1-9As shown, one embodiment of the present invention is: a cable bracket for electrical construction, comprising: a bracket column 1, a horizontal support arm 2 mounted on the bracket column 1, a vertical support arm 3 mounted on the horizontal support arm 2, an electric telescopic rod 4 provided on the bracket column 1, a fixed arc plate 5 mounted on the vertical support arm 3, a limiting mechanism 6 for cable limiting provided on the inner wall of the bracket column 1, an adjusting mechanism 7 for cable adjustment provided on the upper inner wall of the fixed arc plate 5, and the telescopic end of the electric telescopic rod 4 passing through the horizontal support arm 2 for fixed connection. A connecting plate 8 is connected, and a placement arc plate 10 is provided on the connecting plate 8. A flexible rolling wheel 11 is installed on the inner wall of the placement arc plate 10. A fixing groove block 12 is fixedly connected to the top of the placement arc plate 10. A mounting clamp 13 is rotatably connected to the inner wall of the fixing groove block 12. A mounting flange assembly 14 is installed on the circumferential surface of the mounting clamp 13. A fixing column 15 is fixedly connected to the inner wall of the support column 1. A top plate 16 is fixedly connected to the top of the fixing column 15. A guide slide rod 17 is installed on the support column 1.

[0033] There are four support columns 1. A bottom support is set between every two support columns 1. A horizontal support arm 2 is set between every two support columns 1, and the horizontal support arm 2 is located above the bottom support. Two vertical support arms 3 are set between every two horizontal support arms 2. Two symmetrical electric telescopic rods 4 are set on the top of the bottom support of the support column 1. A fixed arc plate 5 is set on the top of each vertical support arm 3. The support columns 1 are installed on the cement wall on both sides of the cable laying trench. The specific number of this support is set according to the cable laying length during the actual installation process.

[0034] Before cable installation, the cable needs to be installed in a suitable area of ​​the cable trench. Workers first need to install the support columns 1 on both sides of the cable trench. After installation, the relevant parts are installed in sequence. Once the preparation is complete, the entire device can be positioned in the cable trench. Simultaneously, a command signal needs to be sent to the electric telescopic rod 4 via an external control terminal to activate it. The electric telescopic rod 4 operates based on data pre-adjusted according to the cable trench depth. The telescopic end of the electric telescopic rod 4 will drive the connecting plate 8 to move and rise. The rise of the connecting plate 8 will drive the placement arc plate 10 to rise synchronously. While the placement arc plate 10 rises, the connecting plate 8 will drive the roller 9 to rise. During the rise of the placement arc plate 10, the placement arc plate 10 will drive the flexible rolling roller 11 to move. Simultaneously, the roller 9 will contact the guide slide rod 17 and... The friction generated by the contact causes the roller 9 to rotate, while the roller 9 is always kept within the guide slide bar 17, which can ensure the stability and guidance of the movement of the connecting plate 8, and directly ensure the stability of the movement of the placement arc plate 10. After the placement arc plate 10 moves a certain distance, the placement arc plate 10 will be located above the ground on both sides of the cable trench. At this time, the cable can be installed on the flexible rolling roller 11 on the inner arc surface of the placement arc plate 10. The flexible rolling roller 11 can prevent the cable sheath from being worn and damaged, and the cable can be laid, placed and sorted at ground level without going down into the trench. Workers can lay the cable while standing on flat ground, without bending over, going down into the trench, or working in narrow spaces. This makes the cable installation safer, more labor-saving, and significantly more efficient. Multiple cables can be arranged neatly above the ground at one time and then laid down simultaneously, with a more regular arrangement. There is no need to repeatedly adjust in the trench, and the installation is completed in one go.

[0035] A roller 9 is rotatably connected to the inner wall of the connecting plate 8. The roller 9 contacts the guide slide rod 17. The top plate 16 is located on the movement trajectory of the mounting clamp 13, and the top plate 16 is used to push the mounting clamp 13 to rotate by reverse compression. A through hole is opened on the surface of the connecting plate 8. The fixing column 15 passes through the through hole on the connecting plate 8, and the diameter of the through hole is larger than the diameter of the fixing column 15. Therefore, the fixing column 15 does not contact the connecting plate 8. The number of flexible rolling rollers 11 is set to multiple, and the multiple flexible rolling rollers 11 are respectively arranged in an arc array on the inner wall where the arc plate 10 is placed.

[0036] After the cable is laid above the ground, the cable is located within the arc plate 10. At this time, the telescopic end of the electric telescopic rod 4 will reset and drive the connecting plate 8 to move back and forth. During the back and forth movement of the connecting plate 8, the connecting plate 8 will simultaneously drive the arc plate 10 to move back and forth. The movement of the arc plate 10 will drive the flexible rolling roller 11 to move. At this time, with the cooperation of the flexible rolling roller 11 and the arc plate 10, the cable can be moved downwards synchronously. During the movement of the arc plate 10, the arc plate 10 will drive the fixed groove block 12 to move. The movement of the fixed groove block 12 will drive the mounting clamp 13 to move. The mounting clamp 13 will drive the mounting flange assembly 14 to move. After the arc plate 10 moves downwards a certain distance, the top plate 16 will contact the arc surface of the mounting clamp 13. The contact and reverse pressure push the mounting clamp 13 to rotate. At this time, the mounting clamp 13 will rotate around the connection with the fixed groove block 12. The rotation of the mounting clamp 13 will drive the mounting flange assembly 14 to rotate synchronously. After the mounting clamp 13 has rotated to a certain angle, it can be positioned above the placement arc plate 10 and limit and wrap the cable, restricting the radial sway and twisting of the cable, so that the cable always remains straight throughout the installation process, preventing twisting, knotting and tangling from the root, greatly reducing manual handling procedures, preventing the cable from arching upward and falling off the supporting arc plate during the positioning and descent, avoiding left and right swinging and twisting of the cable during movement and descent, and making the cable center line coincide with the bracket installation reference. No manual support, correction and alignment are required, and the construction accuracy requirements are met in one positioning.

[0037] Overall working principle: The cable can be placed on the flexible rolling roller 11 on the inner arc surface of the arc plate 10. The flexible rolling roller 11 can prevent the cable sheath from being worn and damaged. It allows the cable to be laid, placed, and arranged at ground level, without the need for trenching. Workers can lay the cable while standing on flat ground, without bending over, going into trenches, or working in narrow spaces. This makes cable installation safer, less labor-intensive, and significantly improves efficiency. Multiple cables can be arranged neatly above the ground at once and then laid down simultaneously, resulting in a more orderly arrangement without repeated adjustments in the trench. The installation is completed in one step. The installation clamp 13 can be positioned above the placement arc plate 10 and limit and wrap the cable, restricting the radial sway and twisting of the cable. This ensures that the cable remains straight throughout the installation process, preventing twisting, knotting, and tangling from the source. It significantly reduces manual handling procedures, prevents the cable from arching upwards and coming off the supporting arc plate during the positioning and descent process, and avoids the cable from swaying and twisting from side to side during movement and descent. It ensures that the cable centerline coincides with the bracket installation reference, eliminating the need for manual support, correction, and alignment. The installation meets the construction accuracy requirements in one step.

[0038] like Figures 1-9As shown, in another embodiment of the present invention based on the above embodiments, the limiting mechanism 6 includes a rubber block 601, which is slidably installed on the inner wall of the guide slide bar 17. A top rod 602 is fixedly installed on the inner wall of the rubber block 601. A rubber block 603 is fixedly connected to the lower inner wall of the top rod 602. An elastic telescopic sleeve 604 is fixedly connected to the upper side of the cross arm 2. A support block 605 is fixedly connected to the telescopic end of the elastic telescopic sleeve 604. A pressure-bearing arc block 606 is fixedly connected to the circumferential surface of the mounting plate 13.

[0039] After the cable moves through the cooperation of the placement arc plate 10 and the flexible rolling wheel 11, the cable is located at the designated installation area height. After the connecting plate 8 moves down a certain distance along the fixed column 15, because the diameter of the connecting plate 8 is larger than the diameter of the sliding sleeve 608, the connecting plate 8 can pass over the sliding sleeve 608. However, the diameter of the connecting plate 8 is smaller than the diameter of the support block 605, so the connecting plate 8 will contact the support block 605 and apply pressure to the elastic telescopic sleeve 604 through the support block 605. At this time, the elastic telescopic sleeve 604 will be compressed. When the elastic telescopic sleeve 604 is compressed by half, the electric telescopic rod 4 will drive the connecting plate 8 to stop moving. At the same time, during the rotation of the mounting clamp 13, the rotation of the mounting clamp 13 will drive the pressure arc block 606 to rotate. After the pressure arc block 606 rotates with the mounting clamp 13, the two pressure arc blocks 606 can contact each other. After the above operations are completed, the operator can place the top rod 602 and the rubber block 1... Insert 601 into the inner wall of the guide slide rod 17 and drive the top rod 602 to slide on the inner wall of the guide slide rod 17. The sliding of the top rod 602 will drive the rubber block 1 601 to move. The movement of the top rod 602 will drive the rubber block 2 603 to move. When the rubber block 2 603 moves down a certain distance, the rubber block 2 603 will be in contact with the pressure arc block 606. At this time, the worker can fix and limit the installation by aligning the mounting hole of the guide slide rod 17 with the mounting hole of the rubber block 1 601. This makes the placement arc plate 10 in a relatively suspended state. It can move slightly downward through the elastic telescopic sleeve 604. At this time, it can form a flexible buffer support to avoid the cable being rigidly squeezed, bumped, or crushed. It provides a uniform, gentle, and controllable upward lifting force so that the cable is not hard pressed on the structure, but in an elastic lifting state. It can effectively eliminate vibration and impact during the installation process, protect the cable insulation layer from being crushed, deformed, or scratched, and improve the cable installation effect and quality of the device.

[0040] The limiting mechanism 6 also includes a warning sleeve 607, which is fixedly connected to the circumferential surface of the fixed column 15. A sliding sleeve 608 is slidably connected to the circumferential surface of the fixed column 15. An elastic telescopic rod 609 is fixedly connected to the inner wall of the arc plate 10. A connecting plate 610 is fixedly connected to the telescopic end of the elastic telescopic rod 609. A contact block 611 is fixedly connected to the inner wall of the connecting plate 610 via one end of a connecting rod, and a movable rubber block 612 is fixedly connected to the inner wall of the connecting plate 610 via the other end of the connecting rod. The circumferential surface of the fixed column 15 contacts the inner wall of the elastic telescopic sleeve 604. The pressure arc block 606 is located on the movement trajectory of the second rubber block 603, and the second rubber block 603 is used to apply pressure to the pressure arc block 606 to maintain stability. The support block 605 is located on the movement trajectory of the first connecting plate 8, and the support block 605 is used to provide buffer support for the first connecting plate 8. A return spring is provided between the sliding sleeve 608 and the fixed column 15. The sliding sleeve 608 is composed of a ring, a connecting rod and a sleeve. The sleeve is fitted on the circumferential surface of the warning sleeve 607.

[0041] When the cable is inside the arc plate 10, the downward movement of the arc plate 10 will cause the elastic telescopic rod 609 to move synchronously. The movement of the elastic telescopic rod 609 will cause the connecting plate 610 to move, which in turn will cause the contact block 611 to move. The movement of the connecting plate 610 will also cause the moving rubber block 612 to move. If the cable bends during the movement, the bent side of the cable will contact the contact block 611 and press the elastic telescopic rod 609 through the contact block 611. At this time, the contact block 611 will move a certain distance according to the degree of bending. The movement of the contact block 611 will cause the connecting plate 610 to move, which in turn will cause the moving rubber block 612 to move laterally. During the process, the movable rubber block 612 will also move downwards through the placement arc plate 10. If the lateral movement of the movable rubber block 612 is too large, the sliding sleeve 608 will be located on the moving trajectory of the movable rubber block 612. After the movable rubber block 612 moves a certain distance, it will contact the sliding sleeve 608 and squeeze and push the sliding sleeve 608 to move downwards, while the warning sleeve 607 will not move. After the sliding sleeve 608 moves downwards a certain distance, it will separate from the warning sleeve 607, so that the warning sleeve 607 can be completely exposed to the outside world, allowing the staff to observe the warning sleeve 607 with the naked eye. This allows the staff to more intuitively and quickly understand whether the cable installation is bent, so that the cable can be adjusted in time, improving the installation efficiency of the device and making the installation simple and clear.

[0042] The adjustment mechanism 7 includes a horizontal sliding groove rod 701, which is slidably installed on the upper inner wall of the fixed arc plate 5. A vertical sliding rod 702 is slidably installed on the inner wall of the horizontal sliding groove rod 701. An arc-pressing plate 703 is fixedly connected to the bottom of the vertical sliding rod 702. A pull rope 704 is installed on the inner wall of the vertical sliding rod 702. A reinforcing rib 705 is fixedly connected to the inner wall of the vertical sliding rod 702.

[0043] During the use of this device, after the placement arc plate 10 moves the cable downwards a certain distance, the placement arc plate 10 will be on the same horizontal plane as the fixed arc plate 5. At this time, the cable will contact the fixed arc plate 5 and stay on the inner arc surface of the fixed arc plate 5. At this time, the operator can insert the horizontal sliding rod 701 into the inner wall of the fixed arc plate 5. The vertical sliding rod 702 will move downwards by gravity and drive the pressure arc plate 703 to move synchronously. At this time, the pressure arc plate 703 will contact the surface of the cable. Then, the operator can pull the pull rope 704 manually or with external equipment. The pull rope 704 will drive the vertical sliding rod 702 to move. The vertical sliding rod 702 will drive the horizontal sliding rod 701 to slide on the inner wall of the fixed arc plate 5. At the same time, the vertical sliding rod 702 will drive the pressure arc plate 703 to move laterally. At the same time, the vertical sliding rod 702 will drive the reinforcing rib 705 to move. At this time, during the movement of the pressure arc plate 703, part of the cable is straightened, improving the installation accuracy of the cable and ensuring the subsequent cable installation effect.

[0044] The adjustment mechanism 7 also includes a first rust-proof sleeve 706, which is fixedly connected to the inner wall of the pressure arc block 606. A second rust-proof sleeve 707 is slidably connected to the circumferential surface of the first rust-proof sleeve 706. The second rust-proof sleeve 707 is in contact with the pressure arc block 606 and is used to protect the parts that are installed and connected. The pressure arc plate 703 is located directly above the fixed arc plate 5.

[0045] When the device is in use, the pressure-bearing arc block 606 rotates synchronously, which in turn drives the anti-rust sleeve 706 to rotate synchronously. The anti-rust sleeve 706 drives the anti-rust sleeve 707 to rotate. When the two pressure-bearing arc blocks 606 are engaged and fit together, the cable installation is nearing completion. The staff needs to tighten the flanges of all relevant parts to strengthen their fixation. During the installation of the locking flange, the anti-rust sleeve 707 can slide according to the length of the locking flange. After the locking flange is installed and fixed, the anti-rust sleeve 707 and the anti-rust sleeve 706 can isolate part of the locking flange to prevent rusting, which can avoid jamming during subsequent cable disassembly and installation, and improve the efficiency and speed of cable installation.

[0046] Overall working principle: The arc plate 10 is in a relatively suspended state and can move slightly downward through the elastic telescopic sleeve 604, forming a flexible buffer support to prevent the cable from being rigidly squeezed, bumped, or damaged. It provides a uniform, gentle, and controllable upward lifting force, so that the cable is not pressed hard against the structure, but is in an elastically supported state. This effectively eliminates vibration and impact during installation, protects the cable insulation layer from being crushed, deformed, or scratched, and improves the cable installation effect and quality of the device. The sliding sleeve 608 can isolate the warning sleeve 607 from contact, allowing the warning sleeve 607 to be completely exposed to the outside world, enabling workers to observe it with the naked eye. When the warning sleeve 607 is in its correct state, workers can more intuitively and quickly understand whether the cable installation is bent, allowing the cable to be adjusted in a timely manner. This improves the installation efficiency of the device and makes the installation simple and clear. The vertical sliding rod 702 will drive the reinforcing rib 705 to move. At this time, the arc-pressing plate 703 will straighten part of the cable during the movement, improving the installation accuracy of the cable and ensuring the subsequent cable installation effect. The second anti-rust sleeve 707 and the first anti-rust sleeve 706 can isolate part of the locking flange to prevent rusting, avoid jamming during subsequent cable disassembly and installation, and improve the installation efficiency and speed of the device for cables.
