Description

Technical Field

[0001] The present invention relates to the technical field of cable brackets, and particularly relates to a cable bracket for a tunnel cable trench. Background Art

[0002] There is a cable trench in the tunnel, and the cables in the cable trench are laid on cable brackets. The cable bracket includes a column for fixedly connecting with the side wall of the cable trench and a bracket arm for supporting the cable.

[0003] During the process of laying cables, it is necessary to drag the cables on the bracket arms and manually move the cables to the correct positions. Since the weight of the cables is generally large, manual dragging is rather laborious. At the same time, during the dragging process, a large sliding friction force will be generated between the cables and the bracket arms, which may cause wear of the cable outer sheath. Therefore, the present invention designs a cable bracket for a tunnel cable trench to solve the above problems. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a cable bracket for a tunnel cable trench, including a column. The inner surface of the column is fixedly connected with a bracket arm. The outer surface of the bracket arm is fixedly connected with a moving mechanism. The side of the moving mechanism away from the bracket arm is fixedly connected with a feeding mechanism. The upper surface of the moving mechanism is fixedly connected with an anti-slip mechanism. The bracket arm serves to place the cables. The moving mechanism can replace manual labor to move the cables to a suitable position on the surface of the bracket arm. The feeding mechanism can sequentially place multiple cables on the upper surface of the bracket arm according to requirements. The anti-slip mechanism facilitates the sliding of the cables on its surface, reduces the friction force during the cable dragging process, and avoids wear of the cable outer sheath. Since multiple bracket arms are fixed on the surface of the column and multiple bracket arms can simultaneously perform the cable dragging operation, only the placement operation of the cables on one bracket arm is shown in the present invention.

[0005] The moving mechanism includes a sleeve block. A chute is opened on the lower surface of the sleeve block. The outer surface of the sleeve block is fixedly connected with a slide rail. The upper surface of the slide rail is slidably connected with a slide table. The upper surface of the slide table is fixedly connected with a support frame. The inner wall of the support frame is fixedly connected with a motor. The output end of the motor is fixedly connected with a rotating shaft. The inner surface of the sleeve block is set to fit the outer surface of the bracket arm and can be sleeved on the outer surface of the bracket arm to provide support and fixation for the feeding mechanism and the anti-slip mechanism. The purpose of the chute is to facilitate the subsequent operation of the feeding mechanism. The slide table can slide along the outer surface of the slide rail and drive the movement of the anti-slip mechanism, thereby moving the cables to a suitable position.

[0006] Further, the inner surface of the sleeve block is fixedly connected with the outer surface of the support arm, and both outer surfaces of the two ends of the rotating shaft are rotatably connected with the inner wall of the support frame.

[0007] Furthermore, the anti-slip mechanism includes an anti-slip box. The inner wall of the anti-slip box is fixedly connected with a U-shaped frame. The inner surface of the U-shaped frame is slidably connected with a support shaft. A sponge wheel is sleeved on the outer surface of the support shaft. The outer surface of the sponge wheel is slidably connected with a collection component. The cable can be placed on the upper surface of the sponge wheel. Since the sponge wheel is made of a soft material, the abrasion of the cable during the cable dragging process is reduced. The U-shaped frame limits the up and down movement of the support shaft and can provide a position when replacing the sponge wheel subsequently.

[0008] Furthermore, the inner surface of the anti-slip box is fixedly connected with the outer surface of the rotating shaft. The inner surface of the sponge wheel is rotatably connected with the outer surface of the support shaft.

[0009] Furthermore, the collection component includes a scraping plate. The bottom of the scraping plate is fixedly connected with an arc-shaped collection plate. The inner wall of the arc-shaped collection plate is fixedly connected with a connecting shaft. The inner wall of the arc-shaped collection plate is fixedly connected with a cylindrical magnet. One side of the cylindrical magnet away from the arc-shaped collection plate is fixedly connected with a magnetic plate. The scraping plate can scrape off the cement block debris or soil debris existing on the outer surface of the sponge wheel. At the same time, the scraping plate is set to be inclined, which is convenient for the debris to fall into the inside of the arc-shaped collection plate. The inner wall of the arc-shaped collection plate is set to be arc-shaped, which is convenient for some soil blocks or mud block debris to fall to the bottom of the inner wall of the arc-shaped collection plate, facilitating centralized collection and treatment. The cylindrical magnet and the magnetic plate adsorb each other, and the arc-shaped collection plate can be attached to the inner wall of the protection box to collect the fallen dust. When the dust is collected to a certain extent, the arc-shaped collection plate can be opened.

[0010] Furthermore, the upper surface of the scraping plate is slidably connected with the outer surface of the sponge wheel. The outer surface of the arc-shaped collection plate is slidably connected with the inner wall of the anti-slip box. Both ends of the connecting shaft are rotatably connected with the inner wall of the anti-slip box. One side of the magnetic plate away from the cylindrical magnet is fixedly connected with the inner wall of the protection box.

[0011] Further, the feeding mechanism includes a connecting plate, the bottom end of the connecting plate is fixedly connected with a pressure sensing component, one side of the pressure sensing component is fixedly connected with an arc-shaped box, the inner wall of the arc-shaped box is fixedly connected with a spring band, the inner wall of the arc-shaped box is slidably connected with a pressing plate, a scraping plate is fixedly connected to the outer surface of the pressing plate, both sides of the pressing plate are fixedly connected with wheel axles, and pressing wheels are rotatably connected to the outer surfaces of the wheel axles. The connecting plate serves to fix the sliding table and the pressure sensing component. The pressing wheels can contact the lower surface of the support bracket arm and roll, and the pressing plate is continuously pressed in real time along with the inclined surface of the lower surface of the support bracket arm, so that the pressing plate can always maintain sliding contact with the lower surface of the support bracket arm. The soil debris or dry cement blocks that may adhere to the lower surface of the support bracket arm are scraped off by the scraping plate, avoiding the influence of cement blocks or attached dust on the subsequent operation of the pressure sensing component. The upper surface of the scraping plate fits and slides with the lower surface of the support bracket arm. The spring band has the same functions as a spring, both having elasticity and a reset function.

[0012] Further, the pressure sensing component includes a roller, a bent rod is fixedly connected to the inner wall of the roller, a sleeve is slidably connected to the inner wall of the bent rod, vertical grooves are formed on the outer surface of the sleeve, an extrusion band is fixedly connected to the inner wall of the sleeve, a T-shaped frame is fixedly connected to the outer surface of the bent rod, a compression spring is fixedly connected to the bottom of the T-shaped frame, and a pressure sensor is fixedly connected to the bottom end of the compression spring. The roller can also roll along the lower surface of the support bracket arm and press the bent rod. As the inclination degree of the lower surface of the support bracket arm varies, the pressing force received by the bent rod also changes at any time. The extrusion band has the same functions as a spring, both having elasticity and a reset function. The roller is arranged directly below the anti-slip box.

[0013] Further, the top end of the connecting plate is fixedly connected to the outer surface of the sliding table, the top end of the spring band is fixedly connected to the bottom of the pressing plate, the outer surface of the sleeve is fixedly connected to the side of the connecting plate away from the sliding table, the top of the extrusion band is fixedly connected to the bottom of the bent rod, the outer surface of the T-shaped frame is slidably connected to the inner surface of the vertical groove, and the bottom of the pressure sensor is fixedly connected to the upper surface of the connecting plate.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. When the cable needs to be laid, the cable is placed on the upper surface of the sponge wheels, and the cable is transported by multiple sponge wheels. The sponge wheels are made of soft materials and will not damage the surface of the cable during the movement of the cable, reducing the wear caused by dragging. At the same time, the cooperation of the moving mechanism and the feeding mechanism can move the cable to a suitable position on the upper surface of the support bracket arm, that is, replacing manual placement of the cable, preventing the inaccurate position of the cable on the upper surface of the support bracket arm in the initial situation, and thus avoiding problems that affect the placement of the remaining cables.

[0016] 2. The U-shaped frame and the support shaft inside the anti-slip mechanism can take out the damaged sponge wheel from the inner wall of the U-shaped frame for replacement, avoiding the long-term contact between the outer surface of the sponge wheel and the cable. Cement debris and solid dust that may exist on the cable surface come into contact with the sponge wheel and cause friction, resulting in damage to the sponge wheel and further causing the problem that the sponge wheel cannot transport the cable.

[0017] 3. The scraping plate inside the collection component can scrape the solid dust on the surface of the sponge wheel onto the inner wall of the arc-shaped collection plate below for collection during the rotation of the sponge wheel. Through the collection of dust by the arc-shaped collection plate and the shielding of the cable below, it can prevent the fallen solid dust from directly adhering to the surface of the cable below, affecting the transportation operation of the cable below. The removal of the solid dust attached to the surface of the sponge wheel by the scraping plate can prevent the solid dust from adhering to the surface of the sponge wheel, resulting in the problem of frictional damage when the cable is transported in contact with the solid dust.

[0018] 4. During the movement of the roller and the bent rod inside the pressure-sensing component, the roller can be continuously pressed by the inclined lower surface of the support bracket arm, and then combined with the pressure sensor to sense the change in the magnitude of the pressure to control the placement of the cable. When the pressure becomes greater and greater, it indicates that it enters deeper into the inside of the support bracket arm. Multiple cables can be placed on the upper surface of the support bracket arm in sequence, avoiding the problem of troublesome manual placement and also avoiding the inaccurate placement position of the cable on the support bracket arm, resulting in the need to re-place the cable.

[0019] 5. The device first scrapes off the cement debris or other solid waste that may exist on the lower surface of the support bracket arm through the scraping plate, avoiding the problem that when the subsequent roller rolls along the lower surface of the support bracket arm, the presence of solid waste causes the roller to shake up and down during movement, making the pressure sensor inaccurate in measuring pressure and resulting in the mobile mechanism placing the cable on the upper surface of the support bracket arm in advance.

Detailed implementation manners

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limited to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0030] Embodiment 1, please refer to Figures 1 - 5 , the present invention provides a technical solution: a cable support for a tunnel cable trench, including a column 1, a support arm 2 is fixedly connected to the inner surface of the column 1, a moving mechanism 3 is fixedly connected to the outer surface of the support arm 2, a feeding mechanism 4 is fixedly connected to the side of the moving mechanism 3 away from the support arm 2, and an anti-slip mechanism 5 is fixedly connected to the upper surface of the moving mechanism 3; the support arm 2 serves to place the cable, the moving mechanism 3 can move the cable to a suitable position on the surface of the support arm 2 instead of manual labor, the feeding mechanism 4 can sequentially place multiple cables on the upper surface of the support arm 2 according to requirements, and the anti-slip mechanism 5 can facilitate the cable to slide on its surface, reduce the friction during the cable dragging process, and avoid abrasion of the cable outer skin. Since multiple support arms 2 are fixed on the surface of the column 1, and multiple support arms 2 can perform cable dragging operations simultaneously, the present invention only describes the cable placement operation on one support arm 2.

[0031] First, when laying cables, place the cables on the upper surface of the anti-slip mechanism 5, which can reduce the wear caused by dragging during the cable dragging process. After the cable dragging is completed, through the cooperation of the moving mechanism 3 and the feeding mechanism 4, move the cable to a suitable position above the support arm 2, and then place the cable down, which can replace manual operation to place the cable on the upper surface of the support arm 2 at a suitable position, preventing the inaccurate position of the cable on the upper surface of the support arm 2 from affecting the subsequent cable placement and the problem of increasing the laying trouble by manually adjusting the cable position.

[0032] The moving mechanism 3 includes a sleeve block 31. A chute 32 is opened on the lower surface of the sleeve block 31. A slide rail 33 is fixedly connected to the outer surface of the sleeve block 31. A slide table 34 is slidably connected to the upper surface of the slide rail 33. A support frame 35 is fixedly connected to the upper surface of the slide table 34. A motor 36 is fixedly connected to the inner wall of the support frame 35. The output end of the motor 36 is fixedly connected to a rotating shaft 37. The inner surface of the sleeve block 31 is set to fit the outer surface of the support arm 2 and can be sleeved on the outer surface of the support arm 2 to provide support and fixation for the feeding mechanism 4 and the anti-slip mechanism 5. The purpose of the chute 32 is to facilitate the subsequent operation of the feeding mechanism 4. The slide table 34 can slide along the outer surface of the slide rail 33 and drive the movement of the anti-slip mechanism 5, thereby moving the cable to a suitable position.

[0033] The inner surface of the sleeve block 31 is fixedly connected to the outer surface of the support arm. Both outer surfaces of the two ends of the rotating shaft 37 are rotatably connected to the inner wall of the support frame 35.

[0034] The anti-slip mechanism 5 includes an anti-slip box 51. A U-shaped frame 52 is fixedly connected to the inner wall of the anti-slip box 51. A support shaft 53 is slidably connected to the inner surface of the U-shaped frame 52. A sponge wheel 54 is sleeved on the outer surface of the support shaft 53. A collection component 55 is slidably connected to the outer surface of the sponge wheel 54. The cable can be placed on the upper surface of the sponge wheel 54. Since the sponge wheel 54 is made of a soft material, it reduces the wear on the cable during the cable dragging process. The U-shaped frame 52 limits the up and down movement of the support shaft 53 and can provide a placement position when replacing the sponge wheel 54 later.

[0035] The inner surface of the anti-slip box 51 is fixedly connected to the outer surface of the rotating shaft 37. The inner surface of the sponge wheel 54 is rotatably connected to the outer surface of the support shaft 53.

[0036] When the cable is placed on the upper surface of the sponge wheel 54, the cable will contact multiple sponge wheels 54 below during the dragging process and drive the rotation of the multiple sponge wheels 54. Since the sponge wheel 54 is made of a soft material, it will not damage the surface of the cable during the cable movement and can provide buffering and shock absorption during the cable transportation process.

[0037] Since the construction is inside the tunnel cable trench, a certain amount of cement debris and solid dust may adhere to the surface of the cable. Therefore, during the cable dragging process, the cement debris and water stains on the cable surface may adhere to the outer surface of the sponge wheel 54, thereby increasing the contact force between the cable and the sponge wheel 54, resulting in a larger moving resistance of the cable and possible damage to the outer surface of the cable. Therefore, it is necessary to scrape off the solid dust that may adhere to the surface of the sponge wheel 54.

[0038] When more and more solid dust adheres to the sponge wheel 54, the hardness of these solid dust is relatively high, and when they come into contact and friction with the sponge wheel 54, they may damage the sponge wheel 54, and the water stains may penetrate into the inside of the sponge wheel 54, causing it to soften and deform. Therefore, after the sponge wheel 54 is used to a certain extent, it needs to be replaced. When the outer surface of the sponge wheel 54 does not contact the cable, the support shaft 53 and the sponge wheel 54 can be slid upward from the inner wall of the U-shaped frame 52, and the support shaft 53 and the sponge wheel 54 can be taken out to facilitate replacing a new sponge wheel 54 on the outer surface of the support shaft 53.

[0039] The collection component 55 includes a scraping plate 551. The bottom of the scraping plate 551 is fixedly connected with an arc-shaped collection plate 552. The inner wall of the arc-shaped collection plate 552 is fixedly connected with a connecting shaft 553. The inner wall of the arc-shaped collection plate 552 is fixedly connected with a cylindrical magnet 554. One side of the cylindrical magnet 554 away from the arc-shaped collection plate 552 is fixedly connected with a magnetic plate 555. The scraping plate 551 can scrape off the cement block debris or soil debris existing on the outer surface of the sponge wheel 54. At the same time, the scraping plate 551 is set to be inclined, which is convenient for the debris to fall into the inside of the arc-shaped collection plate 552. The inner wall of the arc-shaped collection plate 552 is set to be arc-shaped, which is convenient for some soil blocks or mud block debris to fall to the bottom of the inner wall of the arc-shaped collection plate 552 for centralized collection and treatment. The cylindrical magnet 554 and the magnetic plate 555 adsorb each other, and the arc-shaped collection plate 552 can be attached to the inner wall of the protection box to collect the fallen dust. When the dust is collected to a certain extent, the arc-shaped collection plate 552 can be opened.

[0040] The upper surface of the scraping plate 551 is slidably connected with the outer surface of the sponge wheel 54. The outer surface of the arc-shaped collection plate 552 is slidably connected with the inner wall of the anti-slip box 51. Both ends of the connecting shaft 553 are rotatably connected with the inner wall of the anti-slip box 51. The side of the magnetic plate 555 away from the cylindrical magnet 554 is fixedly connected with the inner wall of the protection box.

[0041] When a certain amount of solid dust adheres to the outer surface of the sponge wheel 54, the sponge wheel 54 will come into contact with the lower scraping plate 551 during rotation. The scraping plate 551 can scrape off the solid dust on the surface of the sponge wheel 54 during the rotation of the sponge wheel 54. The scraped solid dust all falls onto the inner wall of the lower arc-shaped collecting plate 552 for subsequent collection. Since multiple support brackets 2 are fixed on the surface of the column 1 and the multiple support brackets 2 can simultaneously perform the cable dragging operation, through the dust collection function of the arc-shaped collecting plate 552, it is possible to prevent the dropped solid dust from adhering to the surface of the lower cable and affecting the transportation of the lower cable.

[0042] In the initial state, the arc-shaped collecting plate 552 is in contact with the inner wall of the anti-slip box 51, forming a wrapping space with the anti-slip box 51. When there is enough dust on the surface of the arc-shaped collecting plate 552, the staff manually pulls the side of the arc-shaped collecting plate 552 close to the magnetic plate 555, and rotates the arc-shaped collecting plate 552 downward around the outer surface of the connecting shaft 553, so that the outer surface of the arc-shaped collecting plate 552 is separated from the inner wall of the anti-slip box 51. At this time, the cylindrical magnet 554 inside the arc-shaped collecting plate 552 is separated from the adsorption of the magnetic plate 555. Place a collecting bag below the arc-shaped collecting plate 552 until all the solid dust on the surface of the arc-shaped collecting plate 552 falls into the inner part of the collecting bag during the downward rotation of the arc-shaped collecting plate 552. Then rotate the arc-shaped collecting plate 552 upward around the outer surface of the connecting shaft 553 until the cylindrical magnet 554 is adsorbed to the magnetic plate 555 again to fix the arc-shaped collecting plate 552.

[0043] Embodiment 2, please refer to Figures 1 - 8 , the present invention provides a technical solution: on the basis of Embodiment 1, the feeding mechanism 4 includes a connecting plate 41. The bottom end of the connecting plate 41 is fixedly connected with a pressure-sensitive component 42. One side of the pressure-sensitive component 42 is fixedly connected with an arc-shaped box 43. The inner wall of the arc-shaped box 43 is fixedly connected with a spring belt 44. A pressing plate 45 is slidably connected to the inner wall of the arc-shaped box 43. A scraping plate 46 is fixedly connected to the outer surface of the pressing plate 45. Both sides of the pressing plate 45 are fixedly connected with wheel shafts 47. A pressing wheel 48 is rotatably connected to the outer surface of the wheel shafts 47. The connecting plate 41 functions to fix the sliding table 34 and the pressure-sensitive component 42. The pressing wheel 48 can contact the lower surface of the support bracket 2 and roll, and continuously presses the pressing plate 45 along the inclined surface of the lower surface of the support bracket 2, so that the pressing plate 45 can always maintain sliding contact with the lower surface of the support bracket 2. The scraping plate 46 scrapes off the possible attached soil debris or dry cement blocks on the lower surface of the support bracket 2 to prevent the subsequent operation of the pressure-sensitive component 42 from being affected by cement blocks or attached dust. The upper surface of the scraping plate 46 fits and slides with the lower surface of the support bracket 2. The spring belt 44 has the same function as a spring, both having elasticity and a reset function.

[0044] The pressure-sensitive component 42 includes a roller 421. A bent rod 422 is fixedly connected to the inner wall of the roller 421. A sleeve 423 is slidably connected to the inner wall of the bent rod 422. Vertical grooves 424 are formed on the outer surface of the sleeve 423. An extrusion belt 425 is fixedly connected to the inner wall of the sleeve 423. A T-shaped bracket 426 is fixedly connected to the outer surface of the bent rod 422. An extrusion spring 427 is fixedly connected to the bottom of the T-shaped bracket 426. The bottom end of the extrusion spring 427 is fixedly connected to a pressure sensor 428. The roller 421 can also roll along the lower surface of the support arm 2 of the bracket and extrude the bent rod 422. As the inclination degree of the lower surface of the support arm 2 varies, the extrusion force received by the bent rod 422 changes at any time. The extrusion belt 425 and the spring have the same functions, both having elasticity and a reset function. The roller 421 is arranged directly below the anti-slip box 51.

[0045] The top end of the connecting plate 41 is fixedly connected to the outer surface of the sliding table 34. The top end of the spring belt 44 is fixedly connected to the bottom of the extrusion plate 45. The outer surface of the sleeve 423 is fixedly connected to one side of the connecting plate 41 away from the sliding table 34. The top of the extrusion belt 425 is fixedly connected to the bottom of the bent rod 422. The outer surface of the T-shaped bracket 426 is slidably connected to the inner surface of the vertical groove 424. The bottom of the pressure sensor 428 is fixedly connected to the upper surface of the connecting plate 41.

[0046] After the cable dragging is completed, at this time, the cable still exists on the upper surfaces of multiple sponge wheels 54. It is necessary to move the dragged cable to a suitable position on the upper surface of the support arm 2 of the bracket through the moving mechanism 3. At this time, the sliding table 34 moves along the outer surface of the slide rail 33 towards the side close to the sleeve block 31, and drives the movement of the support frame 35, the motor 36, the rotating shaft 37, and the anti-slip mechanism 5 during the movement, that is, it can drive the movement of the cable. At the same time, during the movement of the sliding table 34, it can also drive the pressure-sensitive component 42, the arc-shaped box 43, the extrusion wheel 48, and the scraping plate 46 through the connecting plate 41. The extrusion wheel 48 will first come into rolling contact with the lower surface of the support arm 2 of the bracket, and then the upper surface of the scraping plate 46 will come into sliding contact with the lower surface of the support arm 2. As the extrusion wheel 48 continues to rotate while fitting the lower surface of the support arm 2, the lower surface of the support arm 2 is continuously inclined. Therefore, the support arm 2 will continuously extrude the extrusion wheel 48, causing the extrusion wheel 48 and the scraping plate 46 to slide downward along the inner wall of the arc-shaped box 43 and extrude the spring belt 44 at the bottom. Therefore, the scraping plate 46 can be adjusted and changed as the position of the extrusion wheel 48 changes, ensuring that the upper surface of the scraping plate 46 always has a sliding contact with the lower surface of the support arm 2, and can scrape off the possible cement fragments or solid dust on the lower surface of the support arm 2, avoiding the attachment of solid dust on the lower surface of the support arm 2 and affecting the operation of the subsequent pressure-sensitive component 42. The pressure-sensitive component 42 can sequentially place the cable inside the anti-slip box 51 on the upper surface of the support arm 2 according to the inclination degree of the lower surface of the support arm 2 during the movement.

[0047] During the movement of the pressure-sensitive component 42, the roller 421 also rotates along the lower surface of the support arm 2. The support arm 2 will squeeze the roller 421 and the bent rod 422, causing the roller 421 and the bent rod 422 to slide downward along the inner wall of the sleeve 423 and squeeze the internal extrusion belt 425. During the downward movement of the bent rod 422, it will drive the movement of the T-shaped frame 426, causing the T-shaped frame 426 to squeeze the compression spring 427 and the lower pressure sensor 428. As the inclination degree below the support arm 2 increases, the pressure sensed by the pressure sensor 428 will also increase. When the pressure reaches a certain value, the motor 36 above the pressure sensor 428 drives the rotation of the rotating shaft 37 and drives the anti-slip box 51 to rotate downward, so that the cable inside the anti-slip box 51 can slide out along the inner wall of the anti-slip box 51 and fall onto the upper surface of the lower support arm 2, that is, place the first cable at the deepest part of the upper surface of the support arm 2. After the cable is placed, the motor 36 drives the rotating shaft 37 to rotate in the reverse direction, causing the anti-slip box 51 to rotate back to the initial position again, facilitating the subsequent placement of the cable. Therefore, when different magnitudes of pressure are measured by the pressure sensor 428, the second, third, etc. cables can be arranged and placed on the upper surface of the support arm 2 in sequence, realizing the sequential placement of multiple cables and replacing manual placement, saving manpower.

[0048] First, use the scraper 46 to scrape off the possible cement debris or other solid garbage on the lower surface of the support arm 2, to avoid the problem that when the subsequent roller 421 rolls along the lower surface of the support arm 2, the presence of solid garbage causes the roller 421 to shake during movement, resulting in inaccurate pressure measurement by the pressure sensor 428 and causing the moving mechanism 3 to drop the cable in advance.

[0049] After the first cable is placed, the sliding table 34 resets along the outer surface of the slide rail 33, which can drive the reset of the cable feeding mechanism 4 and the anti-slip mechanism 5, facilitating the re-placement of the next cable.

[0050] The specific working process of the present invention is as follows:

[0051] First, when laying a cable, place the cable on the upper surface of the sponge wheel 54. The cable is transported by multiple sponge wheels 54. The sponge wheel 54 is made of a soft material and will not damage the surface of the cable during the movement of the cable, reducing the wear caused by dragging. At the same time, the cooperation of the moving mechanism 3 and the cable feeding mechanism 4 can move the cable to a suitable position on the upper surface of the support arm 2, that is, replace manual placement of the cable, prevent the inaccurate position of the cable on the upper surface of the support arm 2 in the initial situation, and further avoid problems that affect the placement of the remaining cables.

[0052] Through the U-shaped frame 52 and the support shaft 53 inside the anti-slip mechanism 5, the damaged sponge wheel 54 can be taken out from the inner wall of the U-shaped frame 52 for replacement, avoiding the long-term contact between the outer surface of the sponge wheel 54 and the cable. Cement debris and solid dust that may exist on the cable surface come into contact with the sponge wheel 54 and cause friction, resulting in damage to the sponge wheel 54, and further causing the problem that the sponge wheel 54 cannot transport the cable.

[0053] During the rotation of the sponge wheel 54, the scraping plate 551 inside the collection component 55 can scrape the solid dust existing on the surface of the sponge wheel 54 onto the inner wall of the arc-shaped collection plate 552 below for collection. Through the collection of dust by the arc-shaped collection plate 552 and the shielding of the cable below, it is possible to avoid the directly attachment of the fallen solid dust to the surface of the cable below, affecting the transportation operation of the cable below. The removal of the solid dust attached to the surface of the sponge wheel 54 by the scraping plate 551 can avoid the problem that the surface of the sponge wheel 54 is attached with solid dust, resulting in frictional damage when the cable is transported and comes into contact with the solid dust.

[0054] During the movement of the roller 421 and the bent rod 422 inside the pressure-sensitive component 42, the inclined lower surface of the support bracket 2 can continuously press on the roller 421. Then, in cooperation with the pressure sensor 428 to sense the change in the magnitude of the pressure, the placement of the cable can be controlled. When the pressure becomes greater and greater, it indicates that it enters deeper into the inside of the support bracket 2. Multiple cables can be sequentially placed on the upper surface of the support bracket 2, avoiding the troublesome problem of manual placement. At the same time, it also avoids the inaccurate position of the cable placed on the support bracket 2, resulting in the need to re-place the cable.

[0055] Finally, the scraping plate 46 first scrapes off the cement debris or other solid garbage that may exist on the lower surface of the support bracket 2, avoiding the problem that when the subsequent roller 421 rolls along the lower surface of the support bracket 2, the presence of solid garbage causes the roller 421 to jitter up and down during movement, making the pressure sensor 428 measure the pressure inaccurately, resulting in the mobile mechanism 3 prematurely placing the cable on the upper surface of the support bracket 2.
