Problems solved by technology
[0006] The present invention is mainly aimed at the existing maintenance inclined ladder which is generally connected to the power distribution box through a turntable. Although it is convenient to use, the maintenance inclined ladder is not easy to disassemble as a whole. Generally, one power distribution box is equipped with one maintenance inclined ladder. In rural areas, especially in road sections without monitoring, maintenance inclined ladders may be stolen, which will cause large losses in the long run. Providing a convenient way for staff to disassemble can improve the convenience of use, so as to ensure Portable distribution box maintenance folding ladder that is not stolen

The convenient type distribution box overhauling folding ladder comprises a distribution box body and an inclined ladder storage box, an overhauling inclined ladder is arranged in the inclined ladder storage box, a mounting shell is rotatably connectedto the bottom of the distribution box body through a rotary disc, a connecting trough is formed in the mounting shell, a supporting block is arranged at the top end of the inclined ladder storage box, a clamping plate used for being clamped into the connecting trough is arranged on the supporting block, a base is arranged on the lower surface of the clamping plate, an upper meshing group is arranged on the lower surface of the base, a lower meshing group is arranged at the position, corresponding to the upper meshing group, of the lower bottom surface of the connecting trough, the upper meshing group is composed of a plurality of upper meshing blocks, and the lower meshing group is composed of a plurality of lower meshing blocks. The convenient type distribution box overhauling folding ladder is convenient to disassemble for working personnel, and can improve the using convenience, so that it is ensured that the convenient type distribution box overhauling folding ladder is not stolen.
Description
technical field [0001] The invention relates to the field of maintenance of distribution boxes, in particular to a portable folding ladder for maintenance of distribution boxes. Background technique [0002] In the existing circuit construction, the suspended distribution box has a wide range of applications due to its advantages of small footprint and low investment, especially in rural areas. [0003] However, the suspended power distribution box has disadvantages such as inconvenient maintenance and unclear line of sight for meter reading. Especially in rainy night repairs, repair personnel can only use foot buckles to climb poles, because the distance between the pole and the power distribution box is far away and shifts. Inconvenient, there is a big security risk. [0004] In order to reduce the difficulty of suspended work, someone has conducted research on this and designed a maintenance inclined ladder installed on the distribution box. When in use, the maintenance ...
