Description

Technical Field

[0001] This utility model relates to the field of steel pipe tower technology, specifically to a steel pipe tower for anti-climbing power transmission lines. Background Technology

[0002] Steel pipe tower: A lattice-type tower structure composed mainly of steel pipes, with other components made of steel pipes or structural steel. It serves as a support structure for overhead transmission lines to support conductors and lightning protection wires. It ensures that the conductors meet distance requirements from the ground and ground features, and can withstand the loads of the conductors, lightning protection wires, and the tower itself, as well as external loads.

[0003] To prevent people from climbing steel pipe towers and getting close to power lines, which could lead to electric shock, the ladders on the towers are set up with a minimum height of two meters above the ground, and warning signs prohibiting climbing are posted. However, in reality, some people still climb the steel pipe towers, which can easily lead to danger and needs to be improved. Utility Model Content

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a steel pipe tower for anti-climbing transmission lines, including a steel pipe tower body, a crossarm provided above the steel pipe tower body, a ladder extending to the top of the steel pipe tower body, and an anti-climbing device provided near the bottom of the ladder on the steel pipe tower body.

[0008] The anti-climbing device includes a fan-shaped anti-climbing plate fixed to the steel pipe tower body, and the fan-shaped anti-climbing plate is provided with a fan-shaped plate that can be rotated to cover the notch on the fan-shaped anti-climbing plate.

[0009] As an improvement, a fixing frame that is fixedly connected to the fan-shaped anti-climb plate is fixedly provided on the steel pipe tower body.

[0010] As an improvement, the fan-shaped anti-climb plate and the two ends of the fan-shaped plate are respectively provided with a first through hole and a second through hole that cooperate with each other. A pin is provided in the first through hole and a bolt is provided in the second through hole.

[0011] As an improvement, the top of the fan-shaped anti-climb plate is provided with a screw cylinder that mates with the second through hole, and the bolt is located inside the screw cylinder.

[0012] As an improvement, the edge of the fan-shaped plate is provided with a fastener that engages with the edge of the fan-shaped anti-climb plate.

[0013] (III) Beneficial Effects

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] 1. The anti-climbing device is located at the bottom of the ladder and includes a fan-shaped anti-climbing plate and a fan-shaped plate working together to block people who want to climb the steel pipe tower body and prevent them from approaching the ladder.

[0016] 2. The sector plate and the sector anti-climb plate are rotatably connected. When construction workers need to climb the steel pipe tower body, they only need to remove the bolts and then rotate the sector plate to reach the ladder through the notch on the sector anti-climb plate.
