Description

Technical Field

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

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

[0003] The existing cable laying is mostly done by first connecting the cable to the traction rope, and then pulling the traction rope through the traction equipment to pull the cable from the starting point to the end point. In order to improve the utilization of resources and reduce environmental pollution, the traction rope is often required to be recycled after use; Most of the existing traction ropes are recycled through a recycling device after the cable traction is completed, such as the announcement number CN214569708U, a traction rope recycling and winding device for cable laying, which applies a rotational force to the main shaft through an extended pressure rod, and then drives the winding drum to rotate and reel in the traction rope. Although the existing technology can recycle the traction rope, it is relatively cumbersome. It takes time to recycle the traction rope after the cable laying is completed, which seriously affects the cable laying efficiency. In addition, the existing recycling device directly pulls and reels the traction rope, lacks a buffer device, and when the traction rope is stuck, it will cause damage to the traction rope. Summary of the invention

[0004] In view of the problems existing in the prior art, an object 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.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] A cable traction device for cable laying, comprising a traction box, the traction box is provided with a reeling chamber for reeling in a traction rope, a reeling rod is rotatably mounted on the reeling chamber, and the reeling rod is provided with a connecting rope for connecting the traction rope; The traction assembly also includes a first traction roller rotatably mounted on a traction box, a slide groove is provided on the traction box, a mounting plate is vertically slidably mounted in the slide groove, a first spring is fixedly mounted between the top wall of the mounting plate and the slide groove, a first vertical rod is fixedly mounted on the bottom wall of the mounting plate, a second traction roller is rotatably mounted 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 via the first transmission belt is provided on the traction box.

[0007] Furthermore, the transmission assembly includes a second vertical rod fixedly mounted on the bottom wall of the mounting plate, a first transmission roller is rotatably mounted on the second vertical rod, a second transmission roller cooperating with the first transmission roller is rotatably mounted on the traction box, and the first transmission belt is rotatably matched with the second transmission roller.

[0008] Furthermore, a reciprocating screw is rotatably mounted on the inner side wall of the winding chamber, a cloth arrangement block is threadedly mounted on the reciprocating screw, a cloth arrangement opening cooperating with the traction rope is provided on the cloth arrangement block, a limiting rod slidably cooperating with the cloth arrangement block is fixedly mounted on the inner side wall of the winding chamber, and a second transmission belt is rotatably mounted on the reciprocating screw and the winding rod together.

[0009] Furthermore, a first cleaning roller and a second cleaning roller are rotatably mounted on the traction box respectively, and cleaning bristles are evenly and fixedly mounted on the surfaces of the first cleaning roller and the second cleaning roller, and a linkage assembly cooperating with a transmission assembly is provided on the first cleaning roller.

[0010] Furthermore, the linkage assembly includes a first gear fixedly mounted on the first cleaning roller, a second gear meshing with the first gear fixedly mounted on the second transmission roller, a third gear fixedly mounted on the second cleaning roller, and a fourth gear meshing with the third gear fixedly mounted on the first cleaning roller.

[0011] Furthermore, impact rods cooperating with the cleaning hairs are symmetrically fixedly mounted on the side walls of the traction box.

[0012] Furthermore, a rotating rod is vertically rotatably installed in the cloth arrangement opening, and balls are evenly rotatably installed on the top wall and the bottom wall of the cloth arrangement opening.

[0013] Furthermore, a maintenance opening is provided on the side wall of the traction box, and a maintenance door is hinged in the maintenance opening.

[0014] Furthermore, the surfaces of the first traction roller, the second traction roller, the first transmission roller, and the second transmission roller are all provided with anti-slip grooves.

[0015] 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.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (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. (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; (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.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 8 A cable traction device for cable laying, comprising a traction box 1, the traction box 1 is provided with a reeling chamber 2 for reeling in a traction rope, a reeling rod 3 is rotatably mounted on the reeling chamber 2, and the reeling rod 3 is provided with a connecting rope 4 for connecting the traction rope; It also includes a traction component, which includes a first traction roller 501 rotatably mounted on the traction box 1, a slide groove 502 is opened on the traction box 1, a mounting plate 508 is vertically slidably mounted in the slide groove 502, a first spring 503 is fixedly mounted between the top wall of the mounting plate 508 and the slide groove 502, a first vertical rod 504 is fixedly mounted 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 reeling rod 3, and a transmission component for driving the reeling rod 3 to rotate through the first transmission belt 507 is provided on the traction box 1.

[0021] The transmission assembly includes a second vertical rod 601 fixedly mounted 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 rotatably matched with the second transmission roller 603.

[0022] When in 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, and then the motor 506 drives the first traction roller 501 to rotate. At this time, the first spring 503 drives the second traction roller 505 to press the connecting rope 4 on 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, the traction rope will be driven to move into the winding chamber 2 through the connecting rope 4. During the movement of the traction rope, the cable can be driven to move from the starting point to the end point, thereby achieving the purpose of laying the cable. At the same time, during the rotation of the first traction roller 501, the winding rod 3 will be driven 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, thereby improving the cable laying efficiency.

[0023] Since different cables may require different traction ropes, by setting a first spring 503, the first spring 503 can drive the second traction roller 505 through the mounting plate 508 and the first vertical rod 504 to always press the traction rope on the first traction roller 501, so that the device can be suitable for traction ropes of different sizes, thereby improving the applicability of the device. At the same time, the first spring 503, the mounting plate 508, and the first vertical rod 504 drive the second traction roller 505 and the first traction roller 501 to clamp the traction rope together, and transmit the traction rope through the rolling first traction roller 501. When the cable or traction rope is stuck, the traction rope will slide and rub against the first traction roller 501, so that the traction rope will not be damaged by forcibly pulling the traction rope, thereby protecting the traction rope and the cable.

[0024] While the first spring 503 drives the second traction roller 505 to press the traction rope through the mounting plate 508 and the first vertical rod 504, the mounting plate 508 drives the traction rope to contact the second transmission roller 603 through the second vertical rod 601 and the first transmission roller 602, and clamps the traction rope together with the second transmission roller 603, and then drives the second transmission roller 603 to rotate during the movement of the traction rope. During the rotation of the second transmission roller 603, the winding rod 3 is driven to rotate through the first transmission belt 507, and the traction rope is wound up. The winding rod 3 is driven to rotate through the second transmission roller 603. When the traction rope is stuck, the second transmission roller 603 will stop rotating, thereby causing the winding rod 3 to stop rotating, further preventing the traction rope and the cable from being pulled and damaged.

[0025] like Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, a reciprocating screw 701 is rotatably mounted on the inner wall of the winding chamber 2, a distribution block 702 is threadedly mounted on the reciprocating screw 701, a distribution opening 703 cooperating with the traction rope is provided on the distribution block 702, a limiting rod 704 slidably cooperating with the distribution block 702 is fixedly mounted on the inner wall of the winding chamber 2, and a second transmission belt 705 is rotatably mounted on the reciprocating screw 701 and the winding rod 3.

[0026] By adopting the above technical solution, the reciprocating screw 701 is driven to rotate through the second transmission belt 705 during the rotation of the winding rod 3. Since the reciprocating screw 701 is threadedly matched with the arrangement block 702, and the arrangement block 702 cannot rotate under the action of the limiting rod 704, the reciprocating screw 701 drives the arrangement block 702 to move back and forth along the limiting rod 704 during the rotation of the reciprocating screw 701. During the back and forth movement of the arrangement block 702, the traction rope is evenly wound around the winding rod 3 through the arrangement opening 703, thereby effectively preventing the traction rope from being entangled on the winding rod 3 and causing the traction rope to be knotted, making the traction rope unusable, and further extending the service life of the traction rope.

[0027] like Figure 2 , Figure 6 As shown, the traction box 1 is rotatably mounted with a first cleaning roller 801 and a second cleaning roller 802, and cleaning bristles 803 are evenly fixedly mounted on the surfaces of the first cleaning roller 801 and the second cleaning roller 802. The first cleaning roller 801 is provided with a linkage assembly that cooperates with a transmission assembly.

[0028] The linkage assembly includes a first gear 901 fixedly mounted on the first cleaning roller 801, a second gear 902 meshing with the first gear 901 fixedly mounted on the second transmission roller 603, a third gear 903 fixedly mounted on the second cleaning roller 802, and a fourth gear 904 meshing with the third gear 903 fixedly mounted on the first cleaning roller 801.

[0029] The impact rods 10 cooperating with the cleaning hairs 803 are symmetrically fixedly mounted on the side walls of the traction box 1 .

[0030] By adopting the above technical scheme, the second gear 902 is driven to rotate during the rotation of the second transmission roller 603, and then the first cleaning roller 801 is driven to rotate through the first gear 901 during the rotation of the second gear 902. During the rotation of the first cleaning roller 801, the cleaning hairs 803 on the first cleaning roller 801 rotate in the direction opposite 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 direction opposite to the movement of the traction rope. Then, during the rotation of the cleaning hairs 803, 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.

[0031] During the rotation of the cleaning bristles 803, they gradually come into contact with the impact rod 10, and then the impact rod 10 will impact the cleaning bristles 803. Then, under the action of inertia, the gravel on the cleaning bristles 803 will break away from the contact with the cleaning bristles 803, thereby effectively preventing the gravel on the cleaning bristles 803 from adhering to the surface of the traction rope again, thereby improving the cleaning effect of the traction rope.

[0032] like Figure 7 As shown, a rotating rod 11 is vertically rotatably installed in the distribution opening 703, and balls 12 are evenly rotatably installed on the top wall and the bottom wall of the distribution opening 703.

[0033] By adopting the above technical scheme, in the process that the arrangement block 702 drives the traction rope to be evenly arranged on the winding rod 3 through the arrangement opening 703, the arrangement block 702 will drive the traction rope to move back and forth through the arrangement opening 703. In the process that the arrangement opening 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, so that the sliding friction between the traction rope and the side wall of the arrangement block 702 can be converted into rolling friction between the traction rope and the rotating rod 11, thereby further reducing the wear of the traction rope. At the same time, by setting the ball 12, when the traction rope contacts the top wall and the bottom wall of the arrangement opening 703, the traction rope can drive the ball 12 to roll, thereby converting the friction between the traction rope and the top wall and the bottom wall of the arrangement opening 703 into rolling friction between the traction rope and the ball 12, thereby further reducing the wear of the traction rope and extending the service life of the traction rope.

[0034] like Figure 1 As shown, a maintenance opening is provided on the side wall of the traction box 1, and a maintenance door 13 is hinged in the maintenance opening.

[0035] By adopting the above technical solution, after the traction device has been 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, and can also maintain the first transmission belt 507 and the second transmission belt 705, thereby ensuring the normal operation of the traction device.

[0036] like Figure 2 As shown, the surfaces of the first traction roller 501, the second traction roller 505, the first transmission roller 602, and the second transmission roller 603 are all provided with anti-slip patterns.

[0037] By adopting the above technical solution, by providing anti-skid grooves on the surfaces of the first traction roller 501 and the second traction roller 505, the friction between the first traction roller 501 and the second traction roller 505 and the traction rope can be increased, thereby ensuring that the first traction roller 501 and the second traction roller 505 can normally drive the traction rope to move normally, and by providing anti-skid grooves on the surfaces of the first drive roller 602 and the second drive roller 603, the friction between the first drive roller 602 and the second drive roller 603 and the traction rope can be increased, thereby ensuring that the second drive roller 603 can be driven to rotate normally during the movement of the traction rope, thereby ensuring the normal operation of the traction device.

[0038] like Figure 8 As shown, a roller 14 for driving the traction box 1 to move is symmetrically rotatably mounted on the upper portion of the traction box 1 , and a handrail 15 is fixedly mounted on the side wall of the traction box 1 .

[0039] By adopting the above technical solution, when in use, the user can push the traction box 1 to move through the handrail 15, and then the traction box 1 rolls on the ground through the rollers 14 and moves to the destination, which makes it easier to move the traction box 1.

[0040] Instructions for use: When in use, first connect the connecting rope 4 to the traction rope, and then connect the other end of the traction rope to the cable. After the connection is completed, start the motor 506, and then the motor 506 drives the first traction roller 501 to rotate. At this time, the first spring 503 drives the second traction roller 505 through the mounting plate 508 and the first vertical rod 504 to press the connecting rope 4 onto the first traction roller 501. Then, during the rotation of the first traction roller 501, the traction rope will be driven to move into the reeling chamber 2 through the connecting rope 4. During the movement of the traction rope, the cable can be driven to move from the starting point to the end point, thereby achieving the purpose of laying the cable. At the same time, during the rotation of the first traction roller 501, the transmission component and the first transmission belt 507 will be connected. The winding rod 3 is driven to rotate, and the traction rope can be wound around the winding rod 3 during the rotation of the winding rod 3, that is, the traction rope can be wound on the winding rod 3 while the cable is being laid; because the traction ropes required for different cables may be different, by setting the first spring 503, the first spring 503 can drive the second traction roller 505 to always press the traction rope on the first traction roller 501 through the mounting plate 508 and the first vertical rod 504, so that the device can be applicable to traction ropes of different sizes, thereby improving the application 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 traction roller 505 to clamp the traction rope together with the first traction roller 501, and the first traction roller 503 is rolled to move the traction rope to the second traction roller 505. 01 transmits the traction rope. When the cable or traction rope is stuck, the traction rope will slide and rub against the first traction roller 501, so that the traction rope or the cable will not be damaged by forcibly pulling the traction rope; while the first spring 503 drives the second traction roller 505 to press the traction 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 drive the traction rope to contact the second transmission roller 603, and clamps the traction rope together with the second transmission roller 603, and then drives the second transmission roller 603 to rotate during the movement of the traction rope, and drives the winding rod 3 to rotate through the first transmission belt 507 during the rotation of the second transmission roller 603. , and the traction rope is wound up, and the winding rod 3 is driven to rotate by the second transmission roller 603. When the traction rope is stuck, the second transmission roller 603 will stop rotating, so that the winding rod 3 stops rotating, that is, the traction rope is stopped; during the rotation of the winding rod 3, the reciprocating screw rod 701 is driven to rotate by the second transmission belt 705. Since the reciprocating screw rod 701 is threadedly matched with the arrangement block 702, and the arrangement block 702 cannot rotate under the action of the limiting rod 704, then the arrangement block 702 is driven to move back and forth along the limiting rod 704 during the rotation of the reciprocating screw rod 701. During the back and forth movement of the arrangement block 702, the traction rope is evenly wound around the winding rod 3 through the arrangement opening 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. ;

[0041] 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.
