Anti-falling foot nail capable of preventing rope interference

Abstract

The invention relates to an anti-falling foot nail capable of preventing rope interference. The anti-falling foot nail capable of preventing rope interference is composed of a common foot nail and ananti-falling foot nail body and characterized in that the anti-falling foot nail body comprises an installing fixing rod (1), one end of the installing fixing rod (1) is detachably installed on a power transmission iron tower through a fastening part, the other end of the installing fixing rod (1) is connected with a pedal rod (3) into a whole through a spiral rod (2), and the middle section of the spiral rod (2) is in a spiral shape and is provided with a clearance used for allowing a rope to pass in the vertical direction. According to the anti-falling foot nail capable of preventing rope interference, the structural design of an existing anti-falling foot nail is improved, therefore, the problem that in the tower climbing operation process, the rope rubs with the anti-falling foot nailor is separated from the anti-falling foot nail is solved, and meanwhile the problem that the moment of the force bearing point of the anti-falling foot nail is too large is solved.

Description

technical field [0001] The invention relates to an anti-falling spike for preventing rope interference. Background technique [0002] In the power operation and maintenance industry, maintenance personnel often have to carry out tower maintenance operations. In order to protect the safety of tower maintenance operators, transmission towers are often equipped with various types of safety protection measures, and anti-fall nails are one of the measures. kind. Existing anti-fall spikes are generally composed of a fixed structure, a pedal structure and a spiral bending structure, see figure 1 . When in use, the anti-fall spikes are installed on the main material of the transmission tower, and are arranged in cooperation with ordinary spikes on the left and right of the main material of the tower, so that it is convenient for the operator to grasp and step on the tower when climbing the tower. See figure 2 . During use, the safety rope is connected to the safety belt of the ...

Problems solved by technology

[0003] However, in the actual application process on site, because the helical structure of the anti-fall nails is far away from the main material of the iron tower, the feet, legs and body of the tower climber are located between the safety rope and the main material of the iron tower. During the process, the operator's legs and body will constantly touch the safety rope, causing the rope to swing

The swing of the rope not only intensifies the friction between the rope and the anti-fall nails, but also easily causes the rope to accidentally fall off from the helical structure of the anti-fall nails due to the swing, resulting in serious consequences of failure of the anti-fall safety protection

In addition, when a fall occurs, since the stress point of the anti-fall spikes is in the helical structure, the force-bearing condition of the anti-fall spikes is a cantilever structure, and the torque is large, which is likely to cause deformation and damage to the spikes
