Description

Technical Field

[0001] The utility model relates to the technical field of cable pulling, in particular to a power cable pulling device. Background Art

[0002] Power cables are cable products used to transmit and distribute high-power electrical energy in the trunk lines of power systems. They are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas.

[0003] At present, before carrying out on-site construction of cables on electric poles in the field, the traction workpiece needs to be pre-installed manually. However, the existing traction equipment has many parts, and once the angle and direction of the traction equipment are locked on the electric pole, it is difficult to adjust. Repeated disassembly and assembly of the traction equipment will increase the time consumption.

[0004] Regarding the pulling of power cables, how to improve the convenience of the cable pulling process between adjacent poles and facilitate the angle adjustment during the pulling process are technical difficulties that need to be solved. Utility Model Content

[0005] The utility model aims to solve one of the technical problems existing in the prior art or related technology.

[0006] To this end, the technical solution adopted in this utility model is:

[0007] The cam is an angularly adjustable mechanism, which is adapted to move the cam forward and backward, and is configured to move the cam forward and forward through the plurality of axes including a spaced-apart portions of the camshaft and the plurality of axes including a spaced-apart portions.

[0008] In a preferred example, the utility model can be further configured as follows: the stabilization chassis is made of stainless steel, and a counterweight is placed in the inner cavity of the stabilization chassis.

[0009] By adopting the above technical scheme, the combined stabilizing chassis and the slide rail are placed on the ground, and the stabilizing chassis inner cavity counterweight and four reinforcing nails are used to resist the pressure of the traction cable when it is reeled in. After the stabilizing chassis and the slide rail are fixed on the ground, as the slider moves laterally, the outer shell and the winding roller lifted by the support rod can be used at a fixed location to adjust the angle of the traction cable.

[0010] In a preferred example, the utility model can be further configured as follows: an arc-shaped end plate is fixedly installed on the bottom of the compression-resistant splint, and symmetrically distributed pads are fixedly installed on the inner walls of two adjacent compression-resistant splints, and combined bolts are connected inside the pads.

[0011] By adopting the above technical solution, the motor and the winding roller are positioned and clamped by the two combined pressure-resistant clamps, and the arc-shaped end plates at the bottom of the two pressure-resistant clamps are pressed against the outer wall of the stabilizing chassis, so that the traction cable can be stably wound.

[0012] In a preferred example, the utility model can be further configured as follows: the auxiliary rotation gear plate is composed of a gear plate and an annular gasket, and two transverse holes are opened inside the gear plate.

[0013] By adopting the above technical solution, one of the auxiliary gear plates is fixedly installed on the transmission shaft inside the motor by bolts, and the other auxiliary gear plate is fixed to the outer end of the winding roller. At this time, the annular gasket can provide protection for the chain.

[0014] In a preferred example, the utility model can be further configured as follows: buckles are respectively installed on the top and bottom of the support rod, and bearings are fixedly installed in the buckles at the two locations.

[0015] By adopting the above technical solution, the bearing at the bottom of the support rod is installed on the guide rod at the top of the slider. As the slider is subjected to force, it moves outward along the slide rail. At this time, the top of the support rod can provide lifting force to the outer shell in a fixed state. After the lifting angle of the winding roller is stable, the insertion rod can be reassembled in the slide rail and the slider.

[0016] In a preferred example, the utility model can be further configured as follows: a positioning bolt and a gasket are connected to the column head of the clamp penetrating into the inner cavity of the shell.

[0017] By adopting the above technical solution, the clamp is fixed to the bottom of the shell by using positioning bolts and gaskets. When the external force is too large and causes the support rod body to deform, the clamp and shell that can be quickly disassembled can quickly replace the deformed support rod.

[0018] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0019] 1. The utility model controls the operation of the motor, and its internal transmission shaft will drive one of the auxiliary rotating gear discs, and the chain connected to the outside of the auxiliary rotating gear disc can assist the rotation of the other auxiliary rotating gear disc. At this time, the traction cable locked with the cable can be wound toward the outside of the winding roller after adjusting the angle, thereby effectively ensuring that the device can be conveniently fixed and adjusted near the pole, while avoiding the time-consuming repeated assembly of the equipment.

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0031] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0032] A power cable pulling device provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0033] Embodiment 1:

[0034] Combination Figure 1-Figure 5 As shown, the utility model provides a power cable pulling device, including a traction cable 400, an angle adjustment mechanism 300 located outside the traction cable 400, a traction cable bearing mechanism 100 installed on the angle adjustment mechanism 300, and a transmission mechanism 200 installed on the traction cable bearing mechanism 100.

[0035] The traction cable bearing mechanism 100 includes a stabilizing chassis 110, a reinforcing nail 120, a slide rail 130, an insertion rod 140 and a slider 150. The transmission mechanism 200 includes a motor 210, a pressure-resistant splint 220, an auxiliary rotation gear plate 230 and a chain 240. The angle adjustment mechanism 300 includes a support rod 310, a clamp 320, a shell 330, a base 340, a compression spring 350, a positioning wheel 360 and a winding roller 370.

[0036] Specifically, the slider 150 is movably installed inside the slide rail 130, the stabilization chassis 110 is installed on one end of the slide rail 130, the four reinforcement nails 120 are movably installed in the pads around the stabilization chassis 110, the insertion rod 140 is movably installed inside the slide rail 130, the two auxiliary rotation gear plates 230 are located directly above the slide rail 130, the chain 240 is transmission-connected to the outside of the two auxiliary rotation gear plates 230, the motor 210 is installed on one of the auxiliary rotation gear plates 230, the two pressure-resistant clamps 220 are located outside the motor 210, the winding roller 370 is installed on the other auxiliary rotation gear plate 230, the positioning wheel 360 is movably installed at the other end of the winding roller 370, the compression spring 350 is fixedly connected to the groove outside the positioning wheel 360, the base 340 is fixedly installed on the outer end of the compression spring 350, the shell 330 is installed on the outside of the base 340, the chuck 320 is installed at the bottom of the shell 330, and the support rod 310 is movably installed on the chuck 320.

[0037] By fixing two bearings at the top and bottom of the support rod 310 respectively, installing the bearing at the top of the support rod 310 on the chuck 320, and installing the bearing at the bottom of the support rod 310 on the slider 150, as the operator controls the slider 150 to move horizontally along the inner slideway of the slide rail 130, the support rod 310 acting on the top of the slider 150 will lift the chuck 320 and the housing 330 upwards, and the base 340 and the compression spring 350 assembled on the inner side of the housing 330 can cooperate with the winding roller 370 to safely pull the traction cable 400. While winding, the winding roller 370 can be prevented from derailing due to excessive external force. When the motor 210 is running, its internal transmission shaft will drive one of the auxiliary rotating gear disks 230, and the chain 240 connected to the outside of the auxiliary rotating gear disk 230 can assist in rotating the other auxiliary rotating gear disk 230 until the winding roller 370 rotates. At this time, the traction cable 400 locked with the cable can be wound toward the outside of the winding roller 370 after adjusting the angle, thereby effectively ensuring that the device can be conveniently fixed and adjusted near the pole.

[0038] Embodiment 2:

[0039] Combination Figure 2-Figure 5 As shown, on the basis of the first embodiment, the stabilizing chassis 110 is made of stainless steel, and a counterweight is placed in the inner cavity of the stabilizing chassis 110, an arc-shaped end plate is fixedly installed at the bottom of the compression-resistant splint 220, and symmetrically distributed pads are fixedly installed on the inner walls of two adjacent compression-resistant splints 220, and combination bolts are connected inside the pads, and the auxiliary gear plate 230 is composed of a gear plate and an annular gasket, and two transverse holes are opened inside the gear plate.

[0040] One of the auxiliary rotating gear discs 230 is fixedly installed on the transmission shaft in the motor 210 by bolts, and the other auxiliary rotating gear disc 230 is fixed on the outer end of the winding roller 370, and the ring washer is used to protect the chain 240. When the two auxiliary rotating gear discs 230 rotate, the chain 240 protected by the ring washer can maintain stability in the speed change state. The combined stabilization chassis 110 and the slide rail 130 are placed on the ground, and the stabilization chassis 110 inner cavity counterweight block and four reinforcing nails 120 are used to resist the compression of the traction cable 400, and the two combined anti-compression clamps 220 are used to resist the motor 210 and the winding roller 370. 0 is positioned and clamped, and the arc-shaped end plates at the bottom of the two anti-compression clamps 220 press against the outer wall of the stabilizing chassis 110. When the stabilizing chassis 110 and the slide rail 130 are fixed on the ground, as the slider 150 moves laterally, the shell 330 and the winding roller 370 lifted by the support rod 310 can be adjusted at a fixed location for the winding of the traction cable 400 to avoid the skewing of the device caused by the change of force between the traction cable 400 and the pole. At the same time, as the traction cable 400 is wound and tightened, the winding roller 370, which is provided with double anti-compression support by the two anti-compression clamps 220 and the support rod 310, can avoid shaking during rotation.

[0041] Embodiment three:

[0042] Combination Figure 2-Figure 5 As shown, based on the first embodiment, buckles are installed on the top and bottom of the support rod 310, and bearings are fixedly installed in the two buckles. The chuck 320 passes through the inner cavity of the shell 330 and is connected to the column head with positioning bolts and gaskets.

[0043] By installing the bearing at the bottom of the support rod 310 on the guide rod at the top of the slider 150, as the slider 150 is subjected to force and moves outward along the slide rail 130, the top of the support rod 310 can provide a lifting force to the housing 330 in a fixed state until the lifting angle of the winding roller 370 is stable. The insertion rod 140 can then be reassembled in the slide rail 130 and the slider 150, and the clamp 320 can be fixed to the bottom of the housing 330 with the positioning bolts and gaskets. When the external force is too large and causes the rod body of the support rod 310 to deform, the clamp 320 and the housing 330 that can be quickly disassembled can quickly replace the deformed support rod 310, while also facilitating the operator to quickly inspect and repair the device. As the distance between the device and the pole increases, the device can be easily operated by the operator.

[0044] The working principle and use process of the utility model are as follows: the two auxiliary rotation gear plates 230 are fixedly installed on the outer end of the transmission shaft of the motor 210 and the end column of the outer end of the winding roller 370 by bolts in advance, and the two pressure-resistant clamping plates 220 are clamped on the outside of the motor 210 and the winding roller 370 by combined bolts. At this time, the arc-shaped end plates at the bottom of the two pressure-resistant clamping plates 220 will fit the outer wall of the stabilization chassis 110, and the two auxiliary rotation gear plates 230 are connected by the chain 240. At the same time, two bearings are installed on the top and bottom of the support rod 310, and the bottom and top of the support rod 310 are respectively installed on the slider 150 and the clamp 320 with the bearings. As the operator pushes the slider 150, the support rod 310 movably installed on the slider 150 will be forced to push the shell 330 until the shell 330 and the winding roller 370 are away from the ground and lifted upward;

[0045] When in use, after the traction cable 400 wound on the winding roller 370 is locked with the cable to be pulled, the traction state of the traction cable 400 and the pole is controlled by adjusting the lifting angle of the winding roller 370. When the motor 210 is running, its internal transmission shaft will drive one of the auxiliary rotating gear plates 230 to rotate. At this time, the auxiliary rotating gear plate 230 at this location will cooperate with the chain 240 to drive the other auxiliary rotating gear plate 230 to rotate, and the winding roller 370 can continuously wind up the traction cable 400. As the winding roller 370 rotates clockwise, the positioning wheel 360 will expand outward under the elastic tightening action of the compression spring 350. When the motor 210 stops running, the positioning wheel 360 pushed inward by the compression spring 350 will quickly reset until the winding roller 370 is locked. At this time, the device can improve the rapid wire pulling operation of the cable.

[0046] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
