Description

Technical Field

[0001] The present invention relates to the technical field of cable installation, and more specifically, to a cable traction device for cable laying. Background Art

[0002] Cable laying refers to the process of laying and installing cables along the surveyed route to form a cable line. According to the usage scenarios, it can be divided into several laying methods such as overhead, underground, underwater, wall, and tunnel. Reasonably selecting the cable laying method is very important for ensuring the transmission quality, reliability, construction, and maintenance of the line.

[0003] In the existing cable laying, usually the cable is first connected to the traction rope, and then the traction equipment pulls the traction rope to tow the cable from the starting point to the ending point. To improve the utilization of resources and environmental pollution, after the traction rope is used, it is often necessary to recycle the traction rope.

[0004] Most of the existing traction rope recycling is carried out by a recycling device after the cable traction is completed. For example, the cable laying traction rope recycling and coiling device with the publication number CN214569708U applies a rotational force to the main shaft through an extended pressing rod, and then drives the winding disc to rotate and wind up the traction rope. Although the prior art can recycle the traction rope, it is relatively cumbersome. It takes time to recycle the traction rope after the cable laying is completed, seriously affecting the cable laying efficiency. Moreover, the existing recycling device directly pulls and winds up the traction rope, lacking a buffer device, which may cause damage to the traction rope when the traction rope is stuck. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a cable traction device for cable laying, which can improve the cable laying efficiency and reduce the wear of the traction rope.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A cable traction device for cable laying includes a traction box, a winding cavity for winding the traction rope is provided on the traction box, a winding rod is rotatably installed on the winding cavity, and a connecting rope for connecting the traction rope is provided on the winding rod.

[0008] It further includes a traction assembly, and the traction assembly includes a first traction roller rotatably installed on the traction box. A chute is provided on the traction box, and a mounting plate is vertically slidably installed in the chute. A first spring is fixedly installed between the top wall of the mounting plate and the chute. A first vertical rod is fixedly installed on the bottom wall of the mounting plate, and a second traction roller is rotatably installed on the first vertical rod. A motor for driving the first traction roller to rotate is provided on the traction box. A first transmission belt is installed on the winding rod, and a transmission assembly for driving the winding rod to rotate through the first transmission belt is provided on the traction box.

[0009] Further, the transmission assembly includes a second vertical rod fixedly installed on the bottom wall of the mounting plate. A first transmission roller is rotatably installed on the second vertical rod. A second transmission roller for cooperating with the first transmission roller is rotatably installed on the traction box, and the first transmission belt is rotationally engaged with the second transmission roller.

[0010] Further, a reciprocating lead screw is rotatably installed on the inner side wall of the winding cavity. An arranging block is threadedly installed on the reciprocating lead screw. An arranging opening for cooperating with the traction rope is provided on the arranging block. A limiting rod slidably engaged with the arranging block is fixedly installed on the inner side wall of the winding cavity. A second transmission belt is rotatably installed on both the reciprocating lead screw and the winding rod.

[0011] Further, a first cleaning roller and a second cleaning roller are respectively rotatably installed on the traction box, and cleaning hairs are uniformly fixedly installed on the surfaces of the first cleaning roller and the second cleaning roller. A linkage assembly for cooperating with the transmission assembly is provided on the first cleaning roller.

[0012] Further, the linkage assembly includes a first gear fixedly installed on the first cleaning roller. A second gear meshing with the first gear is fixedly installed on the second transmission roller. A third gear is fixedly installed on the second cleaning roller. A fourth gear meshing with the third gear is fixedly installed on the first cleaning roller.

[0013] Further, impact rods cooperating with the cleaning hairs are symmetrically and fixedly installed on the side wall of the traction box.

[0014] Further, a rotating rod is vertically rotatably installed in the arranging opening, and balls are uniformly rotatably installed on the top wall and the bottom wall of the arranging opening respectively.

[0015] Further, a maintenance opening is provided on the side wall of the traction box, and a maintenance door is hinged in the maintenance opening.

[0016] Further, anti-slip patterns are provided on the surfaces of the first traction roller, the second traction roller, the first transmission roller, and the second transmission roller.

[0017] Furthermore, rollers for driving the traction box to move are symmetrically rotatably mounted on the upper part of the traction box, and handrails are fixedly mounted on the side walls of the traction box.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This solution sets a first traction roller. During the rotation of the first traction roller, the cable is pulled by the connecting rope and the traction rope. During the movement of the traction rope, the second transmission roller is driven to rotate. Then, during the rotation of the second transmission roller, the first transmission belt drives the reeling rod to rotate and reel in the traction rope. That is, the traction rope can be reeled in while the cable is pulled. When the traction rope is stuck, the second transmission roller stops rotating, thereby causing the reeling rod to stop rotating, further preventing the traction rope and the cable from being pulled and damaged.

[0020] (2) This solution sets a cloth arrangement block, and drives the reciprocating screw to rotate through the second transmission belt during the rotation of the winding rod. Since the reciprocating screw cooperates with the thread of the cloth arrangement block and the cloth arrangement block cannot rotate under the action of the limit rod, the cloth arrangement block is driven to move back and forth along the limit rod during the rotation of the reciprocating screw. During the back and forth movement of the cloth arrangement block, the traction rope is evenly wound around the winding rod through the cloth arrangement opening, thereby effectively preventing the traction rope from being entangled on the winding rod and causing the traction rope to be knotted, making the traction rope unusable, and further extending the service life of the traction rope;

[0021] (3) This scheme arranges cleaning hairs to drive the second gear to rotate during the rotation of the second transmission roller, and then drives the first cleaning roller to rotate through the first gear during the rotation of the second gear. During the rotation of the first cleaning roller, the cleaning hairs on the first cleaning roller rotate in the direction opposite to the movement of the traction rope. At the same time, during the rotation of the first cleaning roller, the second cleaning roller is driven to rotate through the fourth gear and the third gear. During the rotation of the second cleaning roller, the cleaning hairs on the second cleaning roller rotate in the direction opposite to the movement of the traction rope. Then, during the rotation of the cleaning hairs, the gravel adhered to the traction rope can be driven to break contact with the traction rope, thereby effectively preventing the gravel from accelerating the wear of the traction rope, and further extending the service life of the traction rope.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 8 , a cable traction device for cable laying, including a traction box 1, a reel cavity 2 for winding a traction rope is provided on the traction box 1, a reel rod 3 is rotatably installed on the reel cavity 2, and a connecting rope 4 for connecting the traction rope is provided on the reel rod 3;

[0034] It further includes a traction assembly. The traction assembly includes a first traction roller 501 rotatably mounted on the traction box 1. A chute 502 is formed in the traction box 1. A mounting plate 508 is vertically slidably mounted in the chute 502. A first spring 503 is fixedly installed between the top wall of the mounting plate 508 and the chute 502. A first vertical rod 504 is fixedly installed on the bottom wall of the mounting plate 508. A second traction roller 505 is rotatably mounted on the first vertical rod 504. A motor 506 for driving the first traction roller 501 to rotate is provided on the traction box 1. A first transmission belt 507 is installed on the winding rod 3. A transmission assembly for driving the winding rod 3 to rotate through the first transmission belt 507 is provided on the traction box 1.

[0035] The transmission assembly includes a second vertical rod 601 fixedly installed on the bottom wall of the mounting plate 508. A first transmission roller 602 is rotatably mounted on the second vertical rod 601. A second transmission roller 603 cooperating with the first transmission roller 602 is rotatably mounted on the traction box 1. And the first transmission belt 507 is in rotational cooperation with the second transmission roller 603.

[0036] During use, first connect the connecting rope 4 with the traction rope, and then connect the other end of the traction rope with the cable. After the connection is completed, start the motor 506. Then the motor 506 drives the first traction roller 501 to rotate. Since at this time the first spring 503 drives the second traction roller 505 to press the connecting rope 4 against the first traction roller 501 through the mounting plate 508 and the first vertical rod 504, then during the rotation of the first traction roller 501, it will drive the traction rope to move into the winding cavity 2 through the connecting rope 4. During the movement of the traction rope, it can drive the cable to move from the starting point to the ending point, achieving the purpose of laying the cable. At the same time, during the rotation of the first traction roller 501, it will drive the winding rod 3 to rotate through the transmission assembly and the first transmission belt 507. During the rotation of the winding rod 3, the traction rope can be wound around the winding rod 3, that is, the traction rope can be wound up while the cable is being laid, playing a role in improving the cable laying efficiency.

[0037] Since the towing ropes required for different cables may vary, by setting the first spring 503, the first spring 503 can drive the second towing roller 505 through the mounting plate 508 and the first vertical rod 504 to always press the towing rope against the first towing roller 501. Thus, the device can be applicable to towing ropes of different sizes, thereby improving the applicable range of the device. At the same time, the first spring 503, the mounting plate 508, and the first vertical rod 504 drive the second towing roller 505 to clamp the towing rope together with the first towing roller 501, and the first towing roller 501 in rolling motion drives the towing rope. When the cable or the towing rope gets stuck, the towing rope will have a sliding friction with the first towing roller 501, so that the towing rope or the cable will not be damaged due to forced pulling of the towing rope, playing a role in protecting the towing rope and the cable.

[0038] While the first spring 503 drives the second towing roller 505 to press the towing rope through the mounting plate 508 and the first vertical rod 504, the mounting plate 508 drives the towing rope to contact the second driving roller 603 through the second vertical rod 601 and the first driving roller 602, and clamps the towing rope together with the second driving roller 603. Then, during the movement of the towing rope, it drives the second driving roller 603 to rotate. During the rotation of the second driving roller 603, it drives the winding rod 3 to rotate through the first transmission belt 507 and winds up the towing rope. By driving the winding rod 3 through the second driving roller 603, when the towing rope gets stuck, the second driving roller 603 will stop rotating, so that the winding rod 3 stops rotating, further preventing the towing rope and the cable from being pulled and damaged.

[0039] As Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 As shown, a reciprocating lead screw 701 is rotatably installed on the inner side wall of the winding cavity 2. A distribution block 702 is threadedly installed on the reciprocating lead screw 701. A distribution port 703 matching the towing rope is formed on the distribution block 702. A limiting rod 704 slidably matched with the distribution block 702 is fixedly installed on the inner side wall of the winding cavity 2. The reciprocating lead screw 701 and the winding rod 3 are jointly rotatably installed with a second transmission belt 705.

[0040] By adopting the above technical solution, during the rotation of the winding rod 3, the reciprocating lead screw 701 is driven to rotate by the second transmission belt 705. Since the reciprocating lead screw 701 is in threaded fit with the arranging block 702 and the arranging block 702 cannot rotate under the action of the limiting rod 704, then during the rotation of the reciprocating lead screw 701, the arranging block 702 is driven to move back and forth along the limiting rod 704. During the back-and-forth movement of the arranging block 702, the traction rope is driven to be evenly wound around the winding rod 3 through the arranging port 703, thereby effectively preventing the traction rope from being wound around the winding rod 3 and causing the traction rope to knot, resulting in the inability to use the traction rope, and further extending the service life of the traction rope.

[0041] As Figure 2 , Figure 6 shown, a first cleaning roller 801 and a second cleaning roller 802 are respectively rotatably installed on the traction box 1, and cleaning hairs 803 are evenly and fixedly installed on the surfaces of the first cleaning roller 801 and the second cleaning roller 802. A linkage assembly for cooperating with the transmission assembly is provided on the first cleaning roller 801.

[0042] The linkage assembly includes a first gear 901 fixedly installed on the first cleaning roller 801, a second gear 902 fixedly installed on the second transmission roller 603 and meshing with the first gear 901, a third gear 903 fixedly installed on the second cleaning roller 802, and a fourth gear 904 fixedly installed on the first cleaning roller 801 and meshing with the third gear 903.

[0043] Impact rods 10 for cooperating with the cleaning hairs 803 are symmetrically and fixedly installed on the side wall of the traction box 1.

[0044] By adopting the above technical solution, during the rotation of the second transmission roller 603, the second gear 902 is driven to rotate. Then, during the rotation of the second gear 902, the first cleaning roller 801 is driven to rotate through the first gear 901. During the rotation of the first cleaning roller 801, the cleaning hairs 803 on the first cleaning roller 801 rotate in a direction opposite to the movement direction of the traction rope. At the same time, during the rotation of the first cleaning roller 801, the second cleaning roller 802 is driven to rotate through the fourth gear 904 and the third gear 903. During the rotation of the second cleaning roller 802, the cleaning hairs 803 on the second cleaning roller 802 rotate in a direction opposite to the movement direction of the traction rope. Then, during the rotation of the cleaning hairs 803, the gravel adhered to the traction rope can be driven to be separated from the traction rope, thereby effectively preventing the gravel from accelerating the wear of the traction rope, and further extending the service life of the traction rope.

[0045] During the rotation of the cleaning brush 803, it gradually comes into contact with the impact rod 10. Then, the impact rod 10 will strike the cleaning brush 803. Subsequently, under the action of inertia, the gravel on the cleaning brush 803 will separate from the cleaning brush 803, thereby effectively preventing the gravel on the cleaning brush 803 from adhering to the surface of the traction rope again, and improving the cleaning effect of the traction rope.

[0046] As Figure 7 shown, a rotating rod 11 is vertically and rotatably installed in the arrangement port 703, and rolling balls 12 are respectively and evenly rotatably installed on the top wall and the bottom wall of the arrangement port 703.

[0047] By adopting the above technical solution, during the process that the arrangement block 702 drives the traction rope to be evenly arranged on the winding rod 3 through the arrangement port 703, the arrangement block 702 will drive the traction rope to move back and forth through the arrangement port 703. During the process that the arrangement port 703 drives the traction rope to move, the traction rope will rub against the rotating rod 11 and drive the rotating rod 11 to rotate. Thus, the sliding friction between the traction rope and the side wall of the arrangement block 702 can be converted into the rolling friction between the traction rope and the rotating rod 11, further reducing the wear of the traction rope. At the same time, by arranging the rolling balls 12, when the traction rope contacts the top wall and the bottom wall of the arrangement port 703, the traction rope can drive the rolling balls 12 to roll. Thus, the friction between the traction rope and the top wall and the bottom wall of the arrangement port 703 can be converted into the rolling friction between the traction rope and the rolling balls 12, further reducing the wear of the traction rope, and playing a role in prolonging the service life of the traction rope.

[0048] As Figure 1 shown, a maintenance port is opened on the side wall of the traction box 1, and a maintenance door 13 is hinged in the maintenance port.

[0049] By adopting the above technical solution, when the traction device is used for a period of time, the user can regularly open the maintenance door 13 to inspect and repair the first gear 901, the second gear 902, the third gear 903, and the fourth gear 904, and add lubricating oil to the first gear 901, the second gear 902, the third gear 903, and the fourth gear 904 to ensure their normal transmission. In addition, the first transmission belt 507 and the second transmission belt 705 can also be maintained, playing a role in ensuring the normal operation of the traction device.

[0050] As Figure 2 shown, anti-slip patterns are provided on the surfaces of the first traction roller 501, the second traction roller 505, the first driving roller 602, and the second driving roller 603.

[0051] By adopting the above technical solution, anti-slip patterns are provided on the surfaces of the first traction roller 501 and the second traction roller 505, which can increase the frictional force between the first traction roller 501 and the second traction roller 505 and the traction rope, thereby ensuring that the first traction roller 501 and the second traction roller 505 can drive the traction rope to move normally. In addition, anti-slip patterns are provided on the surfaces of the first transmission roller 602 and the second transmission roller 603, which can increase the frictional force between the first transmission roller 602 and the second transmission roller 603 and the traction rope, so as to ensure that the second transmission roller 603 can rotate normally when the traction rope moves, and further ensure the normal operation of the traction device.

[0052] As Figure 8 shown, rollers 14 for driving the movement of the traction box 1 are symmetrically and rotatably installed on the upper part of the traction box 1, and a handrail 15 is fixedly installed on the side wall of the traction box 1.

[0053] By adopting the above technical solution, during use, the user can push the traction box 1 through the handrail 15. Then, the traction box 1 rolls on the ground through the rollers 14 and moves towards the destination, which facilitates the movement of the traction box 1.

[0054] Usage method: When in use, first connect the connecting rope 4 to the towing rope, and then connect the other end of the towing rope to the cable. After the connection is completed, start the motor 506. Then the motor 506 drives the first towing roller 501 to rotate. Since at this time the first spring 503 drives the second towing roller 505 to press the connecting rope 4 against the first towing roller 501 through the mounting plate 508 and the first vertical rod 504. Then during the rotation of the first towing roller 501, it will drive the towing rope to move into the winding cavity 2 through the connecting rope 4. During the movement of the towing rope, it can drive the cable to move from the starting point to the end point, achieving the purpose of laying the cable. At the same time, during the rotation of the first towing roller 501, it will drive the winding rod 3 to rotate through the transmission component and the first transmission belt 507. During the rotation of the winding rod 3, the towing rope can be wound around the winding rod 3, that is, the towing rope can be wound up while the cable is being laid. Since the towing ropes required for different cables may vary, by setting the first spring 503, the first spring 503 can drive the second towing roller 505 to always press the towing rope against the first towing roller 501 through the mounting plate 508 and the first vertical rod 504, thereby enabling the device to be applicable to towing ropes of different sizes, thus improving the applicable range of the device. At the same time, the first spring 503, the mounting plate 508, the first vertical rod 504 drive the second towing roller 505 and the first towing roller 501 to jointly clamp the towing rope, and the first towing roller 501 that rolls drives the towing rope. When the cable or the towing rope is stuck, the towing rope will have a sliding friction with the first towing roller 501, so that the towing rope or the cable will not be damaged due to forced pulling of the towing rope. While the first spring 503 drives the second towing roller 505 to press the towing rope through the mounting plate 508 and the first vertical rod 504, the mounting plate 508 drives the first transmission roller 602 through the second vertical rod 601 to bring the towing rope into contact with the second transmission roller 603, and jointly clamp the towing rope with the second transmission roller 603. Then during the movement of the towing rope, it drives the second transmission roller 603 to rotate. During the rotation of the second transmission roller 603, it drives the winding rod 3 to rotate through the first transmission belt 507 and winds up the towing rope. By driving the winding rod 3 to rotate through the second transmission roller 603, when the towing rope is stuck, the second transmission roller 603 will stop rotating, so that the winding rod 3 stops rotating, that is, stops winding up the towing rope. During the rotation of the winding rod 3, it drives the reciprocating lead screw 701 to rotate through the second transmission belt 705. Since the reciprocating lead screw 701 is in threaded cooperation with the arranging block 702, and under the action of the limiting rod 704, the arranging block 702 cannot rotate. Then during the rotation of the reciprocating lead screw 701, it drives the arranging block 702 to move back and forth along the limiting rod 704. During the back-and-forth movement of the arranging block 702, it drives the towing rope to be evenly wound around the winding rod 3 through the arranging port 703;During the rotation of the second transmission roller 603, the second gear 902 is driven to rotate, and during the rotation of the second gear 902, the first cleaning roller 801 is driven to rotate through the first gear 901. During the rotation of the first cleaning roller 801, the cleaning hairs 803 on the first cleaning roller 801 rotate in the opposite direction to the movement of the traction rope. At the same time, during the rotation of the first cleaning roller 801, the second cleaning roller 802 is driven to rotate through the fourth gear 904 and the third gear 903. During the rotation of the second cleaning roller 802, the cleaning hairs 803 on the second cleaning roller 802 rotate in the opposite direction to the movement of the traction rope. Then, during the rotation of the cleaning hairs 803, the gravels adhered to the traction rope can be driven to break contact with the traction rope. ;

[0055] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
