Portable ascending operation maintenance ladder

Abstract

The invention relates to a portable ascending operation maintenance ladder. The portable ascending operation maintenance ladder comprises an upper ladder and a lower ladder. The upper ladder and the lower ladder can stretch relatively. A standing platform structure and a fence structure are arranged on the upper ladder; the standing platform comprises a standing platform and a supporting structure. One side of the standing platform is rotatably connected to two sides of the upper ladder, a pair of slide rails are fixedly arranged on the bottom surface of the standing platform in a direction close to the upper ladder, the supporting structure is located below the standing platform, one side of the supporting structure is rotatably connected to two sides of the upper ladder while the other side of the supporting structure is fixedly connected to sliding rollers, the sliding rollers are located in the pair of slide rails and can move along the slide rails, so that the standing platform isfolded or unfolded; the fence structure comprises a frame fence and positioning angle iron, one side of the frame fence is rotatably connected to two sides of the upper ladder, and the positioning angle iron is located below the frame fence, so that the frame fence is limited to a vertical state of the upper ladder. The portable ascend operation maintenance ladder is convenient and rapid to use,and the maintenance work efficiency is improved while the personal safety of the staff is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of electric power maintenance tools, and in particular relates to a convenient maintenance ladder for climbing work. Background technique [0002] According to the "Safe Production Regulations for Electric Power Work", it is strictly forbidden to climb porcelain vases for minor repairs of knife switches and PRTV coating of insulators. As far as the current stage is concerned, outdoor electrical equipment is limited by the actual location and road conditions of the substation in actual work. In some cases, the straight-arm aerial work vehicle is difficult to use, and the construction of the maintenance platform is also restricted by the location of the equipment and the ground conditions, and it takes a lot of time for multiple people to build it, consuming manpower and material resources, which leads to the failure of the maintenance work to be carried out smoothly. [0003] Based on the above factors, it is...
