Problems solved by technology

[0003] The traditional maintenance elevator will occupy most of the space during transportation because the car is too large, which increases the transportation cost and difficulty
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 the basic boarding line, which increases the maintenance personnel's work. Therefore, it is necessary to design a maintenance elevator that is foldable and reduces the difficulty of maintenance personnel on the elevator.

Abstract

The invention discloses a large-stroke maintenance lifting ladder based on a folding type lift car, and relates to the technical field of maintenance lifting ladders. The large-stroke maintenance lifting ladder based on the folding type lift car comprises the folding type lift car, a small guide rail assembly and large guide rails, the folding type lift car is arranged on the small guide rail assembly in a sliding mode, the small guide rail assembly is arranged on the large guide rails in a sliding mode, the large guide rails are used for being arranged on equipment to be maintained, the two sides of the upper end of the small guide rail assembly and the two sides of the lower end of the small guide rail assembly are provided with stop blocks, a plurality of first clamping plates are arranged on the inner side of the small guide rail assembly, the two sides of the folding type lift car are provided with first anti-falling devices, the first anti-falling devices cooperate with the firstclamping plates, a plurality of second clamping plates are arranged on the inner sides of the large guide rails, second anti-falling devices are arranged on the two sides of the small guide rail assembly, and the second anti-falling devices cooperate with the second clamping plates. The provided large-stroke maintenance lifting ladder based on the folding type lift car can be folded into a relatively small size, so that transportation and carrying are facilitated, the large-stroke maintenance lifting ladder can ascend and descend to a position close to a foundation ladder climbing line so that operators can conveniently enter the large-stroke maintenance lifting ladder.

Description

technical field [0001] The invention relates to the technical field of maintenance elevators, in particular to a large-travel maintenance elevator based on a folding car. 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 ...
