Auxiliary device for safe operation of insulating ladder

Abstract

The invention discloses an auxiliary device for safe operation of an insulating ladder. The structure of the auxiliary device comprises an outer barrel and an inner barrel which are movably arranged in a sleeving mode; the two corresponding side faces of the outer barrel are each provided with a long-strip-shaped open hole, the bottom side of each open hole is provided with a plurality of clamping grooves for clamping one screw, each clamping groove comprises a straight groove body and an arc-shaped groove body, the two ends of each straight groove body are open, the upper end of each straight groove body is communicated with the corresponding open hole, and the lower end of each straight groove body is communicated with the corresponding arc-shaped groove body; the two corresponding side faces of the inner barrel are each provided with one screw, each screw is in threaded connection with a nut, the screws are connected with the clamping grooves formed in the outer barrel in a clamped mode, the side walls of the bottom of an inner cavity of the inner barrel are each provided with a bearing screw, one end of each bearing screw is perpendicularly connected with the corresponding side wall of the inner barrel, and the bearing screws are each in threaded connection with an adjusting nut. The device can be installed at the lower end of a ladder rod of the insulating ladder, the advantages of being convenient to assemble, disassemble and carry can be achieved on the premise that the insulating ladder is safely and reliably placed, and the balance and stability of the ladder can be guaranteed according to the characteristic of the ground where the ladder is placed.

Description

technical field [0001] The invention relates to an auxiliary device, in particular to an auxiliary device for safe operation of an insulating ladder. Background technique [0002] The electric power staff cannot do without the insulation ladder during the maintenance process. The insulation ladder is easy to carry and easy to use, but it will encounter a series of difficulties during use, such as how to avoid the insulation ladder from sinking in the soft crop field; How to prevent the insulation ladder from tilting and turning over on the uneven ground; how to place it safely in an environment where the length of the insulation ladder is not enough. We generally use the soil method of laying bricks to solve it. [0003] Under the environment of laying bricks under the above-mentioned insulation ladder, the insulation ladder will sink, overturn, and skew when working in such an environment. What is more dangerous is that it will cause the operator to fall on the ladder and ...
