Compared with the traditional power transmission tower provided with the anti-falling protection device, the power transmission tower is simple in structure, convenient to install and low in manufacturing cost. In addition, the falling prevention foot nail 10 in the embodiment can be applied to a newly built tower body and also can be applied to an old tower body, so that the applicability is strong. In this embodiment, the tower body is a power transmission tower.
Wherein the falling prevention foot nail 10 can be applied to a tower body, a high-rise building or other positions needing climbing. The present application will be described with reference to the application of the falling preventive leg nail 10 to a power transmission tower.

When the falling prevention foot nail 10 in the above embodiment is used, the falling prevention foot nail 10 is fixedly installed on the tower body, the safety rope 400 is connected with the safety belt worn by an operator, and when the operator needs to climb the tower body, the operator sequentially passes through the clearance between the bending piece 300 and the spiral piece 200 and the spiral clearance 220 and moves into the spiral channel 210, so that hanging points can be formed between the safety rope 400 and the spiral piece 200, and the falling prevention foot nail 10 can hang the operator on the tower body through the safety rope 400 and the safety belt when the operator falls down, thereby improving the safety of the operation of the operator on the tower body. When an operator needs to release the fit between the safety rope 400 and the anti-falling foot nail 10, the safety rope 400 in the spiral channel 210 sequentially passes through the spiral gap 220 and the gap between the bending piece 300 and the spiral piece 200, so that the safety rope 400 can be separated from the anti-falling foot nail 10, and the operation is simple and convenient. For traditional anti-falling foot nail, the anti-falling foot nail 10 in this application receives great impact force and takes place to warp at the in-process that the operating personnel falls for screw 200 can drive the bending piece 300 and move towards the one side that is close to screw 200, until bending piece 300 and the lateral wall interference fit of screw 200, and then make screw clearance 220 of screw 200 be closed state and isolated with the external world, in order to prevent that safety rope 400 from deviating from in the screw clearance 220, reduced the risk of safety rope 400 and screw 200 tow hook, improved the security and the reliability of anti-falling foot nail 10.

In this embodiment, the falling-preventing leg nail 10 is in a rod shape, the leg nail body 100 is a leg nail section, the screw member 200 is a screw section, the bending member 300 is a bending section, and the leg nail section, the screw section and the bending section are integrally formed. In this way, the strength and reliability of the falling preventive cramp 10 are improved.
As shown in fig. 1 and 2, the screw member 200 is optionally a screw segment having a rotation angle of at least 270 ° about the central axis of the screw segment. Thus, the safety rope 400 can flexibly move in the spiral channel 210, so that the safety rope 400 is prevented from affecting climbing of operators, and the practicability of the falling-preventing foot nail 10 is improved.
