Description

Technical Field

[0001] The utility model relates to the technical field of anti-falling foot nails, in particular to a safe and economical iron tower anti-falling foot nail. Background Art

[0002] In the maintenance of power transmission lines, tower climbing is a high-frequency and high-risk operation. In recent years, in response to the safety issues of tower climbing, a "fall prevention foot spike" product has been developed. The product has a spiral rotating structure at the tail of the foot spike, which allows the safety rope to enter the rotating structure and provide a hanging point for the safety rope. When the operator accidentally falls, it can prevent the occurrence of falling accidents.

[0003] For example, a Chinese patent with the publication (announcement) number CN115475342A discloses a transmission tower and an anti-fall body, including a foot nail body, a spiral member and a bent member. Among them, one end of the spiral member is connected to the foot nail body, and the spiral member is provided with a spiral channel arranged along the axial direction of the spiral member, and a spiral gap arranged around the axis of the spiral member, and the spiral gap is correspondingly connected to the spiral channel. One end of the bent member is connected to the other end of the spiral member, and the bent member extends toward a side close to the spiral member. The bent member is spaced apart from the spiral member, and when the spiral member undergoes elastic deformation, the bent member can be in contact with the outer wall of the spiral member.
