Description

Technical Field

[0001] The utility model relates to the technical field of electric power facilities, in particular to an anti-falling angle steel tower. Background Art

[0002] my country's power transmission and transformation lines are mainly angle steel towers. In order to ensure the maintenance quality and safe operation of UHV and EHV power transmission and transformation lines, tower maintenance will be used more and more frequently in our maintenance operations, so the maintenance tasks of angle steel towers account for a considerable proportion;

[0003] It has been found in actual use that the existing angle steel towers have the following deficiencies:

[0004] When inspecting and repairing angle steel towers, workers must wear safety ropes or safety belts to ensure their safety. Usually, the safety ropes are connected at the four ends of the angle steel tower. When moving to the other side of the tower, the safety belts must be replaced when passing through the tower material nodes. This increases the number of operating steps for workers, reduces the efficiency of climbing the tower, and the cumbersome steps may increase the probability of workers falling.

[0005] In addition, due to the large diameter of the main material of the angle steel tower, the effective operating radius provided by the working surface during maintenance is limited, and the safety belt needs to be frequently replaced to the connection point near the working position to ensure the safety of the operation. This results in a small single operating area, affecting the maintenance efficiency;

[0006] Therefore, the present application provides a fall-proof angle steel tower to meet the demand. Utility Model Content
