A special maintenance ladder for power supply

Abstract

The invention discloses a repair ladder special for electric repair for ensuring power supply and relates to the technical field of electric power repair equipment. The repair ladder comprises a ladder rack and a plurality of cross rods connected with the ladder rack. The two sides of the ladder rack further comprise two telescopic supporting mechanisms. Twenty-four-polygonal prisms and sleeves matched with the twenty-four-polygonal prisms are arranged between the upper ends of the telescopic supporting mechanisms and the side face of the middle or the lower portion of the ladder rack. The height and the angle of the ladder rack can be controlled through cooperation of the telescopic supporting mechanisms and the sleeves, and the operation requirements under different conditions are met. The lower ends of the telescopic supporting mechanisms comprise ground nails. The bottom of the ladder rack is provided with universal wheels. In addition, the upper side of the ladder rack is provided with a lighting device and an article lifting device which can lift needed articles on the ground to the position of a user, and a serviceman does not need to get to the ground to take the needed articles. The lighting device can be used for lighting at night, and the operation safety is improved. The repair ladder is reasonable in structure and convenient to use, and the labor intensity of the serviceman is relieved.

[0002] At present, with the continuous development of the power system, the safe power supply of the power system has been greatly challenged. In the power maintenance work, it is often necessary to use climbing ladders for climbing operations. As the tree grows, its branches are getting closer to the high-voltage line, sometimes even in contact with the high-voltage line. It is necessary to manually trim the branches of the tree to protect the high-voltage line; at the same time, the power equipment on the high-voltage line often needs to be repaired and maintained. Due to the existing The maintenance ladder has a single function and is cumbersome to use. When repairing equipment on the high-voltage line, the maintenance personnel first climb up the utility pole, then climb up the high-voltage line, and stand or lie on the high-voltage line to check and tighten the connecting nuts. However, the high-voltage line is unstable. The height cannot be controlled, often causing maintenance accidents
