Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power transmission tower technology, and specifically relates to a sleeve-type reinforcement device for power transmission towers. Background Technology
[0002] Transmission towers are the support points for overhead lines. A single-circuit transmission tower has one circuit installed on it, while a double-circuit transmission tower has two circuits installed on it. Transmission tower reinforcement devices are devices that can reinforce transmission towers. However, it is usually not easy to fix transmission towers, the sleeve is not easy to align, or the reinforcement device may loosen over time after it is fixed. In order to solve the problems mentioned in the background, we propose a sleeve-type reinforcement device for transmission towers. Utility Model Content
[0003] The purpose of this utility model is to provide a sleeve-type reinforcement device for power transmission towers, which has the advantage of facilitating the alignment of the reinforcement and wire winding mechanisms.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sleeve-type reinforcement device for a power transmission tower, comprising a right-angle reinforcement plate, an iron box welded to the top of the right rear end of the right-angle reinforcement plate, a steel wire rope disposed inside the iron box, a serrated strip embedded in the surface of the steel wire rope, a limiting block welded to the bottom of the front and the bottom of the right side of the right-angle reinforcement plate, a limiting hole disposed inside the limiting block, and a wire take-up mechanism disposed at the top of the left end of the front of the right-angle reinforcement plate.
[0005] The above technical solution involves welding an iron box to the top of the right rear end of the right-angle reinforcement plate. A steel wire rope is installed inside the iron box, with serrated edges embedded in its surface. Limiting blocks are welded to the bottom of the front and right sides of the right-angle reinforcement plate, with limiting holes inside each block. A winding mechanism is installed at the top of the left end of the front of the right-angle reinforcement plate. The two right-angle reinforcement plates provide symmetrical reinforcement to the transmission tower. The steel wire rope passes through the limiting hole of the other right-angle reinforcement plate, wraps around half a turn, and is then threaded into the winding mechanism to tighten. This automatically aligns the two right-angle reinforcement plates, eliminating the need for laborious balancing and resulting in high efficiency.
[0006] The present invention is further configured such that the take-up mechanism includes a take-up box, which is located at the top of the left end of the front of the right-angled reinforcing plate, and a ratchet is provided inside the take-up box.
[0007] The above technical solution involves setting up a take-up mechanism. The wire rope is threaded into the take-up box. When the wire rope moves backward, the ratchet engages with the serrated strip on the wire rope, preventing the wire rope from loosening.
[0008] The present invention is further configured such that a limiting head is attached to one end of the wire rope near the iron box.
[0009] The above technical solution allows one end of the wire rope to be fixed by setting a limit head.
[0010] The present invention is further configured such that the right-angle reinforcing plate is an L-shape with equal length and width.
[0011] By adopting the above technical solution, and by setting it to an L-shape with equal length and width, the two right-angled reinforcing plates can fit together better when the foundation of the transmission tower is small.
[0012] The present invention is further provided that an insulating gasket is adhered to the inner side of the right-angle reinforcing plate.
[0013] The above technical solution is adopted: by setting insulating gaskets, leakage current is prevented from being transmitted to the right-angle reinforcement plate.
[0014] The present invention is further provided that a winding rod is bolted to the surface of the back of the iron box near the right side.
[0015] The above technical solution involves setting up a winding bar to facilitate the storage of the wire rope when it is not installed.
[0016] The present invention is further configured such that a drag ring is bolted to the front section of the middle right side of the right-angled reinforcing plate.
[0017] The above technical solution, by setting a drag ring, makes it easy to pick up and install the right-angle reinforcement plate.
[0018] The present invention is further configured such that a corner bracket is bolted to the short back of the right-angle reinforcing plate near the insulating pad.
[0019] By adopting the above technical solution, corner brackets can be installed to increase the stability of the right-angle reinforcement plate.
[0020] In summary, this utility model has the following beneficial effects:
[0021] 1. This utility model can automatically align two right-angle reinforcing plates, eliminating the need for laborious balancing and reinforcement, thus achieving high efficiency and saving on installation manpower and costs. By setting a limiting head, one end of the steel wire rope can be fixed. By setting it into an L-shape with equal length and width, the two right-angle reinforcing plates can fit better when the foundation of the transmission tower is small. By setting an insulating gasket, leakage current is prevented from being transmitted to the right-angle reinforcing plates. By setting a wire winding rod, the steel wire rope can be easily stored when not installed.
[0022] 2. This utility model features a wire take-up mechanism. When the wire rope is threaded into the take-up box, the ratchet engages with the serrated strip on the wire rope as it moves backward, preventing the wire rope from loosening. This facilitates installation and saves the trouble of finding other tools to fix it. Attached Figure Description

[0036] Brief description of the usage process: When it is necessary to reinforce the transmission tower, place two right-angle reinforcement plates 1 obliquely and symmetrically on the transmission tower. Remove the steel wire rope 3 from the winding bar 11, pass the steel wire rope 3 through the limiting hole 6 of the other right-angle reinforcement plate 1, and wind it half a turn. Thread the steel wire rope 3 into the winding mechanism and tighten it. It can automatically align with the two right-angle reinforcement plates 1. The other right-angle reinforcement plate 1 will pass the steel wire rope 3 through the bottom of the first right-angle reinforcement plate 1.
