Safety ladder for power construction

Abstract

The invention discloses a safety ladder for power construction. The safety ladder comprises a safety ladder main body, wherein a lifting device is arranged at the top end of the safety ladder main body, the safety ladder main body is hinged to the lifting device through a first hinge, the lifting device comprises a base, a first bevel gear is arranged inside the base, a connecting column is connected to the right end of the first bevel gear, a rotating rod is arranged at the right end of the connecting column, one end, away from the connecting column, of the rotating rod penetrates through theright side wall of the base and is connected with a rotating handle, the first bevel gear is in meshed connection with a second bevel gear, the top end of the second bevel gear is fixedly connected with a nut, the nut is fixed in the middle of the top wall of the base through a second bearing, and a vertically-arranged screw rod is arranged inside the nut. The safety ladder has the advantages that the structure is simple, the operation is convenient and fast, an objective table can be lifted, so that constructors can conveniently take tools, the safety of the constructors is guaranteed, and the working efficiency is improved at the same time.

Description

technical field [0001] The invention relates to the technical field of electric power devices, in particular to a safety ladder for electric power construction. Background technique [0002] Ladders are mostly used in electric power construction, through which workers climb to the power transmission line that needs emergency repair or maintenance; existing ladders for electric power construction generally use two vertical bars and several horizontal bars, but the bottom of each vertical bar only touches the ground at one point , the stability is poor, and accidents are prone to occur, so that the life safety of the construction personnel cannot be guaranteed. In addition, when the construction personnel take the corresponding construction tools, relevant personnel need to pass them from below to the hands of the construction personnel. The above operations are time-consuming and laborious, which is not conducive to work efficiency. The increase has increased the burden on th...
