Fall-proof U-shaped foot pin for iron tower and use method thereof

Abstract

The invention discloses a fall-proof U-shaped foot pin for an iron tower and a use method thereof. The fall-proof U-shaped foot pin for the iron tower comprises a U-shape foot pin and a limiting plate, wherein the U-shape foot pin is arranged on a steel frame of the iron tower, end 1 of an open end of the U-shaped foot pin is fixedly connected with the steel frame, end 2 of the open end of the U-shaped foot pin is connected with the lower portion of the limiting plate, the two ends of the open end of the U-shaped foot pin are vertically arranged, the upper portion of the limiting plate passes through the end 1, and fixedly connected with the steel frame together with the end 1 in close mode, and a limiting groove clamped on the steel frame is formed in the back side of the lower portion of the limiting plate. By using the U-shaped foot pin and the limiting plate, the fall-proof U-shaped foot pin for the iron tower can be conveniently and quickly installed on the steel frame, saves a process of manufacturing holes in the steel frame, and is convenient to assemble and unassembled and maintain. Especially for remolding of a traditional reinforcing steel bar foot pin, an existing installation through hole is used, and then the limiting plate and the U-shaped foot pin can be conveniently and quickly installed on the steel frame of the iron tower, remolding is easy, shinning safety of the traditional iron tower and reliability of the foot pin are greatly improved, remolding cost is low, and the fall-proof U-shaped foot pin for the iron tower further has the advantages of being simple in structure and low in cost.

Description

technical field [0001] The invention relates to a U-shaped foot nail for preventing falling of an iron tower and a using method thereof, belonging to the technical field of iron tower climbing equipment. Background technique [0002] At present, the iron towers of the power transmission lines are all equipped with foot spikes for climbing, which are cylindrical steel bars in a shape. There are no protective measures on the side of the spikes, so that climbers often have accidents due to side slipping of the feet; when the staff climbs up and down the iron tower or shifts the operation on the tower, if the used safety belt hook is buckled Hanging on the spikes will also lose the protective effect due to side slipping and falling out; in addition, the surface of the existing spikes is relatively smooth, and climbers tend to slip when stepping hard, resulting in loose grip and falling towers, and Only one end of the foot nail is connected to the iron tower. After being subject...

AI Technical Summary

Problems solved by technology

When a person falls from the tower, the fixed seat belt and the human body form a single pendulum effect, and the hook and cone shape of the foot nails will cause hanging and poking damage to the human body

In addition, there are also some areas that use the combination of rail-type climbing and falling protectors, anti-fall guide rails and full-body seat belts. Although the safety has been effectively improved, it is difficult to popularize because of its high production cost and complicated installation arrangements.

Chinese patent application (CN201137458Y) discloses a U-shaped foot nail for preventing falling of an iron tower. The two ends of the open end of the foot nail are connected to the steel frame of the iron tower with threads. For matching, the footnail used on the existing traditional iron tower is a steel bar, which is connected to the steel frame through one end of the footnail thread. It needs to drill another hole to meet the installation of U-shaped footnails, and the transformation is complicated. Inconvenient installation and maintenance
