Liftable mobile ladder stand and working method thereof

Abstract

The invention relates to the field of machining, in particular to a liftable mobile ladder stand and a working method thereof. The liftable mobile ladder stand comprises a lower ladder part and an arc-shaped upper ladder part; one side of the top of the upper ladder part is provided with a sliding wheel, and the sliding wheel is suitable for abutting against the outer wall of a to-be-welded barrelbody; and the upper ladder part and the lower ladder part are connected through a height adjusting assembly. The liftable mobile ladder stand can get close to the outer wall of the to-be-welded barrel body conveniently through the arc-shaped upper ladder part and make effective contact with the outer wall of the to-be-welded barrel body through the sliding wheel, the sliding wheel can rotate along with rotation of the barrel body, and accordingly, the welding stability is ensured. In addition, the installation height of the upper ladder part of the liftable mobile ladder stand can be adjustedthrough the height adjusting assembly, so that the welding requirements of barrel bodies different in diameter can be met.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a liftable mobile ladder and a working method thereof. Background technique [0002] When welding the outer wall of a circular cylinder, workers need to operate the welding machine on the upper part of the outer surface of the cylinder. The cylinder is rotated and welded on the turning platform following the turning platform. The workers go up and down the cylinder, and the operation of the welding machine adopts a conventional straight ladder. shortcoming: [0003] 1. The straight ladder needs to be moved every time, which consumes manpower and is inconvenient to move; [0004] 2. The straight ladder leans against the outer wall of the cylinder and requires workers to support it, and the stability is relatively poor; [0005] 3. There is no operating platform, which is not convenient for workers to operate the welding machine; [0006] 4. When welding the oute...
