Description

Technical Field

[0001] This utility model relates to the technical field of power pole climbing devices, and in particular to a type of anti-falling foot nail for power towers. Background Technology

[0002] Transmission line towers are tower-shaped structures used for power transmission. Their structural characteristics include a space truss structure for all tower types, with members primarily composed of single equilateral angle steel or composite angle steel. The materials generally used are Q235 and Q345 steel. The members are connected using coarse bolts, relying on shear force for connection. The entire tower consists of angle steel, connecting steel plates, and bolts. Some components, such as the tower feet, are welded from several steel plates into a single assembly. Therefore, hot-dip galvanizing for corrosion protection, transportation, and construction are extremely convenient. For towers with a height of less than 60m, foot spikes are installed on one of the main members of the tower to facilitate climbing for construction workers. These foot spikes are generally installed at regular intervals on the tower members at a certain height above the ground, forming a climbing path.

[0003] To address this, patent No. 201921692078.9 discloses a closed-end anti-fall-from-height foot spike, comprising a pole climbing spike. One end of the pole climbing spike has a pressure pin opening. A reinforcing nut is installed between the flat washer and the anti-theft nut. A clamping nut is installed on one side of the flat washer, and a clamping nut is installed between the clamping nut and the flat washer. Anti-slip protrusions are provided on the outer side of the pole climbing spike, and a spike closing ring is installed at the lower end of the pole climbing spike. The long axis is at a 45° angle to the spike axis, providing good anti-slip properties. The reinforcing block enhances the pressure resistance of the spike closing ring, thus strengthening the overall reliability of the device, preventing the safety belt from slipping off the hook, and eliminating safety hazards during displacement on power towers. The reinforcing nut increases the stress point of the spike without twisting. The reinforcing nut has a flared hole, which enhances the overall strength of the pole climbing spike, allowing it to be used as a sturdy component.

[0004] The existing technical solutions described above have the following drawbacks: Although the pressure-bearing capacity is increased by connecting the studs to the climbing tower feet via argon arc welding, and the addition of reinforcing blocks can enhance the pressure resistance of the closed-loop foot feet, traditional foot feet are usually welded when disassembling and assembling them. Maintenance personnel need to carry welding tools and perform welding operations in confined spaces at high altitudes. This operation is not only dangerous but also carries the risk of tools falling, greatly affecting the efficiency of maintenance work. At the same time, since transmission lines are exposed to the outdoors for a long time, they are susceptible to loosening and displacement due to environmental factors such as wind and vibration. Once the foot feet become loose, it will not only pose a safety hazard to subsequent climbing operations but may also lead to a decrease in the stability of the tower structure, threatening the safe operation of the entire transmission line. Summary of the Invention

[0045] Working principle: When the worker installs the foot nail body 11;

[0046] First, by inserting one end of the main bolt 22 into the interior of the mounting cylinder 13 and rotating the foot nail body 11 clockwise, the main bolt 22 and the mounting cylinder 13 can be threaded together. After the main bolt 22 is fully threaded together with the mounting cylinder 13, the connector 21 can be inserted into the upper part of the mounting cylinder 13 and the connector 21 can press one end of the two sets of auxiliary plates 27, so that the two sets of auxiliary plates 27 can be flipped horizontally and locked into the interior of the slot 25.
