Description

Technical Field

[0001] The utility model relates to the technical field of overhead power transmission, in particular to a corner tower with a climbing-assisting ladder. Background Art

[0002] Corner towers, a common type of tower in power transmission lines, are also called corner poles or corner towers. They play a vital role in power systems. They are mainly used for installation at the intersection or corners of two lines in power transmission and transformation lines to change the direction of the line. Existing corner towers generally do not have climbing ladders. Maintenance personnel need to rely on the outer hollow steel structure of the corner tower to climb to the top of the tower to repair the transmission line. Since the outer steel structure of the corner tower is mostly inclined, the safety rope of the maintenance personnel is unstable, which increases the risk of maintenance personnel climbing. In addition, if the maintenance personnel fall during the climbing process, there is no obstruction on the way of falling. The maintenance personnel will fall directly from a high altitude to the ground. The large drop makes the chance of survival of the maintenance personnel extremely small. Utility Model Content
