Technical Field
[0001] The utility model belongs to the technical field of power transmission line construction tools, in particular to an anti-displacement cable lead-in device for power transmission line construction. Background Art
[0002] When laying cables for power transmission lines, it is necessary to pass the pulling rope through the pipeline. At this time, a wire guide is needed. The wire guide is an excellent auxiliary tool for pulling the guide rope in the pipeline. The smooth and elastic surface allows the perforator to easily pass through narrow passages. The wire guide consists of three parts: copper core, glass fiber reinforcement layer, high-pressure low-density polyethylene protective layer (smooth, strong, and resistant to harsh environments).
[0003] When using a wire guide to pull the guide rope in the left and right directions, due to the lack of specific supporting structures on the front and rear sides of the wire guide, the wire guide itself may shake and displace in the front and rear directions when pulling and applying force to the guide rope. At this time, construction workers are required to apply force to fix the wire guide, which is inconvenient. Therefore, there is a need for an anti-displacement cable wire guide for power transmission line construction, which can provide oblique support for the front and rear sides of the wire guide, thereby avoiding displacement of the wire guide during use, thereby improving the stability of the wire guide itself during use. Utility Model Content
[0004] The purpose of the utility model is to provide an anti-displacement cable guide for power transmission line construction, which can obliquely support the front and rear sides of the guide, thereby avoiding the displacement of the guide during use, thereby improving the stability of the guide itself during use, so as to solve the technical problems raised by the above-mentioned background technology.
[0005] The utility model provides a technical solution to the above-mentioned technical problems as follows: an anti-displacement cable guide for power transmission line construction, comprising a bracket: two symmetrically arranged vertical rods are welded to the front and rear sides of the bracket, ear blocks are welded to the surfaces of the vertical rods, and a rotating rod is installed on the surfaces of the left and right ear blocks for common rotation, a gear is fixedly connected to the right end of the rotating rod, an L-shaped plate is welded to the surface of the vertical rod on the right side, cross blocks are welded to the top and bottom of the L-shaped plate, a threaded rod and a rack are arranged on the outside of the L-shaped plate, and a support plate is fixedly installed on the surface of the rotating rod.
[0006] Preferably, the threaded rod is threadedly connected to the transverse block located on the upper side, and the rack is slidably connected to the transverse block located on the lower side.
[0007] Preferably, the end of the threaded rod is rotationally connected to the rack.
[0008] Preferably, two symmetrically arranged sleeves are welded on the surface of the support plate, the inner wall of the sleeve is slidably connected with a support rod, the surface of the sleeve is threadedly connected with a bolt rod, and the end of the bolt rod passes through the inner cavity of the sleeve and abuts against the support rod.
[0009] Preferably, an X-shaped arm is welded between the left and right vertical rods.
[0010] Preferably, the surface of the bracket is wrapped with a woven cloth cover.
[0011] 1. The beneficial effect of the utility model is as follows: the utility model drives the rack to move downward by rotating the threaded rod, and then the rack drives the rotating rod to swing through the gear, so that the rotating rod drives the support plate to flip and resist against the ground, so that the support plate obliquely supports the bracket, and the front and rear sides of the wire guide can be obliquely supported, thereby avoiding the displacement of the wire guide during use, thereby improving the stability of the wire guide during use.
[0012] 2. The utility model can extend the bottom of the support plate through the coordinated use of the sleeve, the support rod and the bolt rod, thereby avoiding the situation where the support plate cannot contact the ground when the ground is sunken and uneven.
[0013] 3. The utility model reinforces the connection between the left and right vertical rods by setting an X-shaped arm, connects the two vertical rods as a whole, and improves the stability of the connection between the two vertical rods.
[0014] 4. The utility model wraps the surface of the bracket by setting a woven cloth cover, thereby avoiding the accumulation of sweat on the surface of the bracket due to long-term contact with the hands of construction workers, improving the cleanliness of the surface of the bracket, and the woven cloth cover is easy to disassemble and clean.

[0025] Embodiment 2:
[0026] Figure 1-4The utility model shows an anti-displacement cable guide for power transmission line construction of an embodiment of the utility model, which includes a bracket 1: two symmetrically arranged vertical rods 2 are welded on the front and rear sides of the bracket 1, and ear blocks 3 are welded on the surfaces of the vertical rods 2. A rotating rod 4 is installed on the surfaces of the left and right ear blocks 3 for common rotation. A gear 5 is fixedly connected to the right end of the rotating rod 4, and an L-shaped plate 6 is welded on the surface of the vertical rod 2 on the right side. The top and bottom of the L-shaped plate 6 are welded with cross blocks 7. The outside of the L-shaped plate 6 is provided with a threaded rod 8 and a rack 9. A support plate 10 is fixedly installed on the surface of the rotating rod 4, and two symmetrically arranged sleeves 11 are welded on the surface of the support plate 10. A support rod 12 is slidably connected to the inner wall of the sleeve 11. A bolt rod 13 is threadedly connected to the surface of the sleeve 11. The end of the bolt rod 13 penetrates into the inner cavity of the sleeve 11 and abuts against the support rod 12. Through the coordinated use of the sleeve 11, the support rod 12 and the bolt rod 13, the bottom of the support plate 10 can be extended to avoid the situation that the support plate 10 cannot contact the ground when the ground is concave and uneven.
[0027] Working principle: When the utility model is used, the user drives the rack 9 to move downward by rotating the threaded rod 8, and then the rack 9 drives the rotating rod 4 to swing through the gear 5, so that the rotating rod 4 drives the support plate 10 to flip and contact the ground, so that the support plate 10 obliquely supports the bracket 1. If the ground is concave and uneven, the support rod 12 can be extended to a suitable length under the sleeve 11, and then the support rod 12 is tightened by the bolt rod 13, so that the support plate 10 can be in contact with the ground and bear force. When the use is finished, refer to the above steps and retract the support plate 10 to a vertical state, which can reduce the space occupied by the support plate 10 and avoid the situation that the support plate 10 occupies more space during the transportation or storage of the bracket 1, thereby realizing oblique support for the front and rear sides of the wire guide, avoiding the displacement of the wire guide during use, and thereby improving the stability of the wire guide itself during use.
[0028] To sum up: the anti-displacement cable guide for power transmission line construction drives the rack 9 to move downward by rotating the threaded rod 8, and then the rack 9 drives the rotating rod 4 to swing through the gear 5, so that the rotating rod 4 drives the support plate 10 to flip and resist against the ground, so that the support plate 10 obliquely supports the bracket 1, thereby achieving oblique support for the front and back sides of the guide, avoiding the displacement of the guide during use, and thereby improving the stability of the guide during use.
