CN-117365264-B - Anti-falling foot nail for pole tower of overhead transmission line

Abstract

The invention discloses an anti-falling foot nail for an overhead transmission line pole tower, which comprises a pedal body, wherein one side surface of the pedal body is fixedly connected with a fixing screw rod, a nut group is sleeved on the outer side thread of the fixing screw rod, an anti-slip strip is arranged on the surface of the pedal body, a safety hook is arranged on the other side surface of the pedal body, an oblique angle is formed between the safety hook and the horizontal direction of the pedal body, and a plurality of groups of pedal bodies are uniformly and alternately fixedly arranged on the left side and the right side of a line pole body through the fixing screw rod. The invention overcomes the defects that in the prior art, a high-altitude operator is easy to tread and slide or unstable in standing in the using process of the foot nails for the overhead transmission line towers, so that the overhead transmission line towers slide and scratch is caused, and also solves the problem that part of the foot nails are inclined due to long-time exposure of the transmission towers to the action of wind.

Description

Anti-falling foot nail for pole tower of overhead transmission line Technical Field The invention relates to the technical field of electric power field operation tools, in particular to an anti-falling foot nail for an overhead transmission line tower. Background In recent years, personal casualty safety accidents caused by falling from a high place in the power industry many times occur, and accident reasons are analyzed from the technical level, so that the worker loses safety belt protection in the process of climbing the iron tower, and the most effective solving measure at present is to install a falling-preventing guide rail of the power transmission iron tower. Although the anti-falling guide rail can make up the defect that no safety protection exists in the process of climbing the foot nails and climbing the ladder, the safety closed-loop protection of the high-altitude operation is realized, the anti-falling guide rail has the defects of overhigh equipment cost and complex operation in the actual application, so that the anti-falling guide rail still cannot be generally adopted in China at present. The falling-preventing foot nail has the characteristics of simple structure, convenience in installation, safety, reliability, strong universality and the like, and the installation does not influence the operation of a circuit. However, the situation that the high-altitude operators step on independent nails is easy to occur, such as stepping slip or unstable standing, and the situations of slipping, scratching and the like are caused, so that certain potential safety hazards exist. Disclosure of Invention The invention aims to solve the technical problem of providing an anti-falling foot nail for an overhead transmission line tower so as to improve the safety of overhead operation.
