Mobile multi-functional folding ladder

Abstract

The invention discloses a mobile multi-functional folding ladder. The mobile multi-functional folding ladder comprises two hinged top plates and ladder frames separately arranged at the bottoms of twotop plates, the ladder frames each comprise two parallel supporting legs arranged at the bottom of the corresponding top plate and a plurality of lateral supporting rods arranged between the corresponding two supporting legs, universal wheels are arranged at the bottoms of the supporting legs, movable sleeves are slidably arranged on the supporting legs, positioning sleeves are arranged at the bottoms of the movable sleeves, the universal wheels are located in the positioning sleeves, tension mechanisms are arranged between the movable sleeves or / and the positioning sleeves and the supportinglegs, a connecting mechanism is arranged between the movable sleeves on the two parallel supporting legs of the same ladder frame, an angle positioning mechanism is further arranged between the adjacent two ladder frames, and the angle of unfolding between the two ladder frames is locked by the angular positioning mechanism. The mobile multi-functional folding ladder solves the problem that a current folding ladder cannot meet the requirements of stable movement and continuous work of an operator sitting on the folding ladder, and solves the problems that the folding ladder is turned over dueto center-of-gravity shift during the movement and the folding ladder cannot be stopped and positioned in time during the movement.

Description

technical field [0001] The invention relates to the technical field of engineering ladders, in particular to a mobile multifunctional folding ladder. Background technique [0002] Folding ladder is also called herringbone ladder. It is composed of two rotatable connecting plates and a ladder frame. When used, it can increase the height to facilitate the decoration of the roof and walls with a higher height. At present, it has been widely used during the renovation period. However, we have found in the actual use process that although various construction sites attach great importance to safety issues, when operators use folding ladders, if they do not sit on the connecting plate Because the climbing height is not high, it is also convenient to get down. Basically, when you need to move the area, you will climb down first and then manually carry it to the desired position before climbing up. There is generally no problem with safety. However, if When workers are sitting on ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve some or some technical problems existing in the prior art, the present invention provides a mobile multifunctional folding ladder, which not only solves the problem that the current folding ladder cannot meet the needs of operators sitting on the folding ladder to move smoothly and continuously. Work problems, and avoid the center of gravity shifting and overturning during the moving process and the problem of being unable to stop and position in time during the moving process
