A folding ladder outside the factory building

Abstract

The invention discloses a foldable crawling ladder outside a plant. The foldable crawling ladder comprises a folding ladder, guide rails, a storage box, a limiting plate and sliding blocks, wherein the guide rails are mounted in a building wall in a nested mode; the storage box is arranged on the ground below the guide rails; the folding ladder comprises two sets of folding rods, and the two sets of folding rods are arranged in parallel and connected through rotating shafts a; the sliding blocks are provided with sliding grooves corresponding to the guide rails, one end of each sliding block is clamped in the corresponding guide rail, a mounting seat is arranged at the other end of each sliding block, and the upper end of each outer linkage rod and the lower end of the corresponding inner linkage rod are mounted in the corresponding mounting seat through the corresponding rotating shaft a; and the limiting plate is buckled on a rotating shaft b and the rotating shaft a closest to the rotating shaft b. The folding ladder of the foldable crawling ladder outside the plant is folded and stored in the storage box in a non-working state, the storage box is covered with a box cover and then sealed, and the folding ladder cannot be eroded by wind, rain and sunlight; and since the storage box is arranged on the ground, the folding ladder can be conveniently overhauled and maintained, and personal safety of workers is guaranteed.

Description

technical field [0001] The invention relates to the technical field of climbing tools, in particular to a folding ladder outside a factory building. Background technique [0002] For the convenience of line maintenance and roof maintenance, many buildings, especially factories, are equipped with ladders on the outside. Since the ladder is installed outside the building, it is unavoidable for non-staff to climb at will, which has certain safety hazards; and due to wind, sun and rain, the ladder is easy to rust, which poses a great threat to the personal safety of the staff. Since the existing ladder is fixed inside the building wall, it is very troublesome to replace. [0003] Patent No. "201420276585.5" is the invention patent of "Folding Ladder for Roof Maintenance". The movable ladder is fixedly connected to the fixed ladder through a lock, which avoids climbing by non-staff. [0004] Patent No. "201420413283.8" is an invention patent of "a folding ladder for roof mainte...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problems that the existing ladders for roof maintenance are easily corroded and inconvenient to maintain, the present invention develops a foldable ladder outside the factory building. The ladder can be stretched and laid on the wall when in use, and folded and stored in a tool box when not in use. , less susceptible to erosion and easier to maintain
