The invention discloses a power cable overhaul ladder which comprises a base, a ladder frame and supporting columns. One end of the ladder frame is hinged to the base; the two ends of the supporting columns are installed on the base and the ladder frame correspondingly; the ladder frame comprises a plurality of short frames which are sequentially connected in series; ladder frame inserting blocks are arranged at one end of each short frame, ladder frame inserting grooves are formed in the other end of the ladder frame, and the ladder frame inserting blocks of the short frame at one end are hinged to the base; the short frames are provided with sliding grooves and first penetrating pin holes, the extending direction of the sliding grooves is parallel with that of the short frames, the first pin holes communicate with the sliding grooves, and the axes of the first pin holes are perpendicular to the extending direction of the sliding grooves; and a sliding block is hinged to one end of each supporting column, arranged in the corresponding sliding groove and provided with second pin holes of which the diameter is the same as that of the first pin holes. The ladder frame is formed by connecting the multiple short frames in series, the length of the ladder frame can be increased by inserting and connecting the multiple short frames, the sliding grooves and the two kinds of pin holes enable the supporting columns to be fixed to a plurality of positions of the sliding grooves, and the structural stability of the overhaul ladder is adjusted conveniently.
Description
technical field [0001] The invention relates to the technical field of power tools, in particular to a power cable maintenance ladder. Background technique [0002] In power maintenance operations, it is often necessary to overhaul aerial cables located at higher positions. Especially when carrying out maintenance and laying operations to outdoor overhead cables, due to the lack of necessary supports, construction workers need to lean the maintenance ladder frame for climbing on the power cables during construction, and then carry out construction operations. Under this mode of operation, on the one hand, the maintenance ladder is not fixed stably, and it is easy to slip and fall, causing construction personnel to be injured. On the other hand, under the gravitational action of the maintenance ladder and the construction personnel, it is very easy to cause the cables to be strained or broken. [0003] In the related art, there is an electric maintenance vehicle, which is e...
