Description

Technical Field

[0001] The present invention relates to the technical field of power equipment installation, and in particular to a power distribution and power supply cable laying device and a use method thereof. Background Art

[0002] In power distribution and power supply projects, cables need to be laid for power transmission. The current mainstream cable laying method in our country is to build underground pipe corridors, install brackets on the side walls of the pipe corridors, and then lay the cables on the brackets. On the one hand, it can make rational use of space, and on the other hand, it can also place the cables in an orderly manner, which is convenient for later inspection and maintenance.

[0003] At present, when laying cables for such projects, the traditional method is to place the cables on the ground of the corridor by a wire-laying machine or a traction machine, and then workers place the cables on the brackets in order. This type of operation is extremely inefficient and consumes too much physical energy for the construction workers. On the other hand, it is easy to cause wear of the cables, affecting their service life. Therefore, a traction machine is also used on the market to move the carrier. During the movement of the carrier, the wire is laid while it is being laid. However, in actual operation, only one group of cables can be placed on one side at a time, and during the wire-laying process, the wire roller frame uses wire-laying traction to make the wire roller rotate passively. In this process, the cable is stretched, which can easily damage the internal structure of the cable and easily cause the cable to fall from the corridor bracket. For this purpose, a power distribution cable laying device and a method of using the same are provided to solve the above problems. Summary of the invention

[0049] Working principle: When the device is used, firstly, the plurality of outer hexagonal rotating tubes 136 are removed in sequence, and then the reel with the cable wound is sleeved on the outer surface of the outer hexagonal rotating tube 136 so that the two can rotate synchronously, and then the outer hexagonal rotating tube 136 is movably sleeved on the outer surface of the rotating shaft 131, and the outer hexagonal rotating tube 136 is movably plugged with the ratchet 139 through the slot 1311 and the insert 1310;

[0050] Then, the cable laying unit 2 is adjusted according to the height of the cable support on both sides inside the pipe gallery and the spacing on both sides, and the lifting adjustment screw rod 224 is rotated clockwise to make the sliding link 221 move up and down on the outer surface of the column 212 to adjust its height, and then the lifting positioning nut 225 is screwed upward to be close to the bottom of the sliding link 221 for support, so that the support arm 222 is above the corresponding cable support, and then the telescopic fixing bolt 226 is loosened, and then the support arm 222 is pulled outward, so that the multiple cable laying guide frames 23 move to the outermost side of the top of the cable support, and then the telescopic fixing bolt 226 is tightened, and then the multiple cable laying guide frames 23 are adjusted from back to front in sequence, and the L-shaped telescopic bracket 231 is moved outward from the inside of the telescopic arm 223 by rotating the driving screw rod 232, so that the multiple positioning guide rollers 234 are distributed in a stepped manner, and at this time, the multiple groups of cables at the bottom are sequentially passed through the multiple rotating guide seats 233 and the positioning guide rollers 234, so that the multiple groups of cables on the same side can be synchronously and evenly spaced and arranged horizontally on the cable support;

[0051] At this time, the traction hook 16 and the traction anti-slip connecting rod 15 are installed with the external traction machine, and the traction machine drives the entire mobile loading unit 1 to move. During the movement, the roller member 12 rolls on the ground. At this time, the roller member 12 drives the transmission shaft 143 to rotate through the first-level transmission gear chain 144, and the transmission shaft 143 drives a group of rotating shafts 131 to rotate through the driving bevel gear 146 and the transmission bevel gear 145. The rotating shaft 131 drives other rotating shafts 131 to rotate synchronously in turn through multiple multi-stage transmission gear chains 142, so that when the entire sliding carrier 11 moves forward, the rotating shaft 131 drives the cable roller to actively rotate to release the cable, thereby reducing the pulling of the cable and avoiding damage to the cable. At the same time, during the movement, the ratchet 139 and the pawl 138 are used to make the outer hexagonal rotating tube 136 self-rotate in the same direction on the outer surface of the rotating shaft 131, so that during the cable release process, when some cables are pulled, they can be adaptively rotated and released without affecting the rotation and release of other cable rollers.

A power distribution cable laying device according to claim 7, characterized in that: The wire laying guide frame (23) comprises an L-shaped telescopic bracket (231), a driving screw rod (232), a rotating guide seat (233) and a positioning guide roller (234); the L-shaped telescopic bracket (231) is movably inserted into the interior of the telescopic arm (223); the driving screw rod (232) is rotatably connected to the interior of the L-shaped telescopic bracket (231); the driving screw rod (232) is threadedly connected to the telescopic arm (223); the rotating guide seat (233) is rotatably connected to the top of the support arm (222); and the positioning guide roller (234) is rotatably connected to the interior of the top of the L-shaped telescopic bracket (231).

9. A method for using a power distribution cable laying device according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1, assembling the cable reel, removing the outer hexagonal rotating tube (136), then sleeve the cable reel on the outer surface of the outer hexagonal rotating tube (136), and then flexibly sleeve the outer hexagonal rotating tube (136) on the outer surface of the rotating shaft (131), so that the slot (1311) and the insert (1310) are flexibly plugged; S2, cable laying adjustment, rotating the lifting adjustment screw rod (224) clockwise to make the sliding link (221) rise to the top of the corresponding cable support, pulling the support arm (222) outward to move the cable laying guide frame (23) to the outermost side of the top of the cable support, rotating the driving screw rod (232) to move the L-shaped telescopic support (231) outward from the inside of the telescopic arm (223), so that the multiple positioning guide rollers (234) are distributed in a stepped manner; S3, traction laying, the external traction machine drives the entire mobile loading unit (1) to move through the traction hook (16) and the traction anti-slip connecting rod (15), the roller member (12) rolls on the ground, and the roller member (12) drives the rotating shaft (131) to rotate synchronously through the transmission member (14), so that the cable roller actively rotates to release the cable, and at the same time, the ratchet (139) and the pawl (138) are used to make the external hexagonal rotating tube (136) rotate in the same direction on the outer surface of the rotating shaft (131) to cope with additional external traction.
