When the staff is operating the diagonal steel tower, they can also stand on the cable terminal platform to operate. The cable terminal platform is at a certain height from the ground. When the staff is operating on it, in order to prevent the risk of falling, they need to use a safety belt or secondary protection rope to ensure their own safety.

The safety anti-falling device for angle steel towers described in the utility model connects the safety rope with the connecting ring, and then places the foot in the inner cavity of the concave plate, and fixes the foot of the staff member through a mechanical connection. Then, when the foot leaves, the protection of the concave plate is released through the second spring, and when an accidental slip occurs, the first fixed plate is quickly stopped under the action of the third spring to prevent the staff member from falling.

[0004] In the above technical solution, multiple equally spaced fixing devices need to be installed on an angle steel tower, which has a high production cost. In addition, the fixing devices are fixedly connected to the triangular steel.
