Problems solved by technology

[0002] In electric power maintenance, it is often necessary to overhaul the electrical equipment and power supply lines located at a higher position. The commonly used climbing tool is the maintenance ladder. The traditional maintenance ladder mainly depends on the friction between the maintenance ladder itself and the ground and the relying objects. However, the anti-slip effect of this kind is extremely unsatisfactory. The maintenance ladder often slips and causes the operator to be injured. Therefore, in actual use, someone often needs to support the ladder on the ground to prevent slipping, but the anti-slip effect of this operation is still not good. Ideal, but also increases the labor intensity of the operator and reduces the maintenance efficiency

Abstract

The invention discloses an electric power overhaul ladder which comprises an overhaul ladder body. At least two fixed looped links are arranged at the front end of the overhaul ladder body and are in hinged connection with the overhaul ladder body. The fixed looped links are of closed ring shape. Each fixed looped link is formed by a fixed ring block and a movable ring block, wherein one end of the movable ring block is in hinged connection with the fixed ring block, and the other end of the movable ring block is in pin connection with the fixed ring block and the overhaul ladder body. The length of the movable ring block is one fourth to one third that of the fixed ring block. The electric power overhaul ladder is easy and convenient to operate. When the electric power overhaul ladder is lifted for overhauling, the front end of the overhaul ladder traditionally leans against a supporting object, and besides, the overhaul ladder can be conveniently, quickly and reliably hung and buckled with the supporting object through the fixed looped links. Consequently, the overhaul ladder is effectively prevented from slipping and falling, a traditional manual slip prevention operation is eliminated, construction safety is improved, and manpower is saved.

technical field [0001] The invention relates to an electric maintenance ladder, which belongs to the field of electric maintenance equipment. Background technique [0002] In electric power maintenance, it is often necessary to overhaul the electrical equipment and power supply lines located at a higher position. The commonly used climbing tool is the maintenance ladder. The traditional maintenance ladder mainly depends on the friction between the maintenance ladder itself and the ground and the relying objects. However, the anti-slip effect of this kind is extremely unsatisfactory. The maintenance ladder often slips and causes the operator to be injured. Therefore, in actual use, someone often needs to support the ladder on the ground to prevent slipping, but the anti-slip effect of this operation is still not good. It is ideal, but also increases the labor intensity of the operator and reduces the maintenance efficiency. Contents of the invention [0003] The object of ...
