Abstract

The invention relates to a right-angle hanging ladder for multi-purpose safety tools, which comprises a first aluminum alloy climbing ladder section and a second aluminum alloy climbing ladder section; the ends of the first aluminum alloy climbing ladder section and the second aluminum alloy climbing ladder section pass through an adjustable rotating shaft The device is connected; the adjustable shaft device is provided with a lock; the outer end of the first aluminum alloy ladder section is provided with a fixed hook; the outer end of the second aluminum alloy ladder section is provided with a steering hook.

Description

technical field [0001] The invention belongs to the technical field of electric power tools, and relates to a right-angle hanging ladder, in particular to a self-made "3+1" right-angle hanging ladder of multi-purpose safety tools. Background technique [0002] Ladders are highly used safety tools in transmission line maintenance operations. In the current transmission line maintenance work, the ladder tools used mainly include the following two types: [0003] 1. The hanging ladder used to enter the wire from the cross arm in the maintenance operation of the transmission line. When working, the hook at one end is hooked on the wire, and the other end is tied to the cross arm, so that the operator can enter the wire along the ladder without going through the insulator. This tool will cause scars to the wire, and the center of gravity of the operator will lean forward, which will result in long working hours and great physical exertion. [0004] 2. Ladders used in urban pow...
