Description

Technical Field

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

[0002] With the rapid development of the national economy, especially the rapid development of communications, electricity, household appliances and other fields, the wire and cable industry has been greatly stimulated. Therefore, the requirements for distribution network construction have become higher and higher, and the proportion of cables used in distribution network lines has also increased significantly;

[0003] At present, in the process of laying power cables, it is often necessary to pull and tug the cables. However, although there is a cable reel for rotating transportation during the pulling and tug of the cables, due to the heavy weight of the cables and the long moving distance, the cables will directly contact the ground. During the pulling and tug of the workers, the cables will rub against the ground, which not only makes the pulling and tug of the cables more laborious, seriously affecting the laying efficiency of the cables, but also causes wear of the cable skin, affecting the safe use of the cables. Utility Model Content

[0004] In order to overcome the shortcomings of the background technology, the utility model discloses a power cable laying device. During the laying and pulling process of the cable, the utility model can provide segmented sliding support for the cable to avoid contact between the cable and the ground, thereby effectively preventing friction damage to the cable skin during pulling and dragging of the cable.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

Specifically, the support mechanism 2 includes a support seat 19, a roller 21 and an arc plate 13, both sides of the lower surface of the support seat 19 are provided with rollers 21 that can rotate along the axial direction of the side rods 6, the upper surface of the support seat 19 is provided with an inner concave arc surface 15 adapted to the cable, and the two side edges of the inner concave arc surface 15 respectively correspond to the rollers 21 on both sides of the lower surface of the support seat 19, and when the cable is placed on the inner concave arc surface 15 on the upper part of the support seat 19, the rotation direction of the roller 21 is the same as the axial direction of the cable;

[0029] In order to prevent the cable from falling off the support seat 19 during the process of pulling and hauling the cable, a curved plate 13 corresponding to and matching the inner concave curved surface 15 is detachably installed on the upper part of the support seat 19. Specifically, two bosses 16 are provided on the upper surface of the support seat 19, which are respectively arranged on the outer side of the inner concave curved surface 15 and axially along the side rod 6. One end of the boss 16 is provided with a slot 17 arranged axially along the side rod 6. Both ends of the two sides of the curved plate 13 in the same direction are provided with an extension plate 14 extending outward. The plate surface of the extension plate 14 facing the other end of the side of the curved plate 13 is provided with a plug plate 12 matching the slot 17. When the cable is clamped to the support seat 19 After the upper concave arc surface 15 is placed on the upper part, the concave surface of the arc plate 13 is facing the cable, and the plug plates 12 on both sides of the arc plate 13 are inserted into the slots 17 on the end faces of the boss 16. The arc plate 13 is buckled on the upper part of the cable, which can effectively prevent the cable from falling off from the support seat 19 when the cable is pulled. In order to prevent the arc plate 13 from falling off during the pulling process, when the support seat 19 supports the cable, the notch of the slot 17 is facing the opposite direction of the cable pulling direction. In this way, during the pulling process of the cable, even if the cable rubs against the arc plate 13, the plug plates 12 on both sides of the arc plate 13 will not fall off the slots 17;

[0030] In order to facilitate the storage of several support seats 19 of the support frame 1, a slide groove 7 is provided on the opposite surface of the two side rods 6 along the axial direction of the side rods 6, and the end of the slide groove 7 away from the end plate 5 is an open structure, and side edges 18 matching the slide groove 7 are provided on both sides of the support seat 19.

[0031] In the second embodiment, during the process of segmented support of the cable by multiple support seats 19, as the cable is pulled, the support seat 19 moves with the cable. In order to prevent the support seat 19 from accidentally tilting forward or backward to affect the pulling and pulling of the cable, both sides of the lower surface of the support seat 19 are provided with mounting grooves 20 arranged axially along the side rod 6, and a plurality of rollers 21 arranged axially at intervals along the mounting groove 20 are detachably installed in the mounting groove 20, wherein the length of the mounting groove 20 is adapted to the length of the support seat 19, and the plurality of rollers 21 are evenly distributed in the mounting groove 20, thereby effectively ensuring the horizontal stability of the support seat 19 during movement;

[0032] With daily use, the roller 21 is prone to damage. In order to facilitate the staff to disassemble and replace the roller 21, vertical side slide grooves 23 are provided on the opposite surfaces of the two side walls in the installation groove 20. The lower end of the side slide groove 23 is an open structure, and a limit groove 22 is provided on the inner bottom surface of the upper end of the side slide groove 23.

Both ends of the rotating shaft 25 are embedded with elastic The ends of the rotating shaft 25 on both sides of the roller 21 are in contact with the corresponding side slide grooves 23, and the elastic beads 24 at the ends of the rotating shaft 25 are contracted to push the roller 21 to slide upward. When sliding to the limiting groove 22 at the upper end of the side slide groove 23, the elastic beads 24 at the ends of the rotating shaft 25 pop out to complete the installation of the roller 21. When disassembling, you only need to apply force to pull the roller 21 downward to use the elasticity of the elastic beads 24 to separate the two ends of the rotating shaft 25 from the limiting groove 22, thereby completing the disassembly of the roller 21.

[0033] In the third embodiment, when laying short-distance cables, it is only necessary to pull the cables for a short distance. In this case, there is no need for multiple support seats 19. In order to enable multiple support seats 19 installed on the support frame 1 to complete the sliding support of the cables without removing the support seats 19, the height of the side rod 6 is the same as the height of the support seat 19, and the upper edge of the end plate 5 is provided with an arc-shaped recess 4 corresponding to and matching the concave arc surface 15 on the upper surface of the support seat 19.
