Abstract

A snake-type pusher relates to the technical field of high-altitude fall protection devices for iron towers. The invention solves the problem that the slider cannot normally walk on the slideway when the power transmission and distribution personnel climb the iron tower in the existing high-altitude anti-fall protection device for the iron tower, and when the power transmission and distribution personnel falls from a high altitude, there is no gap between the slideway and the slider. Locking in time will cause the high-altitude fall protection device of the iron tower to fail to lock and hang the human body in time, resulting in a large relative displacement, causing the human body to fall, and causing potential safety hazards for the staff. The snake head part, the snake body part and the snake tail part of the present invention are sequentially connected by rotation from left to right, one end of the support device is positioned and installed on the upper end of the snake head part, the other end of the support device supports the slider, and one end of the traction device is connected to the snake tail part. The upper end is fixedly connected, the other end of the traction device cooperates with the slideway, and the traction device is connected with the waist of the staff. The invention is used in the high-altitude fall protection device for iron towers.
