Folding telescopic type maintenance lifting ladder

Abstract

The invention provides a folding telescopic maintenance lifting ladder. The folding telescopic maintenance lifting ladder comprises a bridge compartment, a small guide rail mounting frame, a large guide rail, a guide wheel device and anti-falling devices, wherein the bridge compartment is installed on the small guide rail mounting frame through the guide wheel device, the small guide rail mountingframe is installed in the large guide rail through the guide wheel device, the large guide rail is fixed to the to-be-maintained equipment, and the anti-falling devices are correspondingly installedon the two sides of a bottom plate of the bridge compartment and the two sides of the small guide rail mounting frame. The bridge comprises a folding door, a back plate, the bottom plate, a first sidewall, a second side wall, a telescopic rod switch and a folding door switch, wherein the back plate is hinged to the first side wall, the second side wall and the bottom plate, the bottom plate is hinged to the first side wall, the second side wall and the folding door, and the folding door is connected to the side wall through door plate pin shafts. According to the folding telescopic maintenance lifting ladder, the connecting positions of the bridge compartment are connected through hinges so that the bridge compartment can be folded when not used, the space is saved, the bridge compartmentis composed of middle connecting rods, disassembling, assembling and transporting are convenient, and the structure stability is good.

Description

technical field [0001] The invention relates to the technical field of maintenance elevators, in particular to a foldable telescopic maintenance elevator. Background technique [0002] With the development of science and technology, aerial work equipment has gradually appeared. When the aerial work equipment has a technical failure, it will be costly to disassemble and repair it. This requires a maintenance lift to transport the maintenance personnel to the maintenance position safely and reliably. . [0003] The traditional maintenance elevator will occupy most of the space during transportation because of the large volume of the car, which increases the cost and difficulty of transportation. At the same time, in the actual working situation, due to the change of the height difference during the lifting process, the traditional maintenance elevator cannot use a guide rail to realize the guidance of the car, resulting in the car not being able to descend to the vicinity of ...
