Conveniently lifted anti-falling ladder with more stable center of gravity

Abstract

The invention discloses a conveniently lifted anti-falling ladder with a more stable center of gravity and relates to the technical field of ladders. The ladder comprises a main ladder, wherein a chute is formed in one side of the main ladder, a pushing device is slidably connected to the inner wall of the chute, a limiting frame is arranged outside the pushing device in a sleeving manner, the limiting frame is fixedly connected to the main ladder, and a supporting plate is rotatably connected to the end at the bottom on one side, close to the chute, of the main ladder. The conveniently liftedanti-falling ladder with the more stable center of gravity can be reinforced automatically when the ladder is likely to overturn backward as the inclination angle becomes small, so that the problem that the ladder is overturned backward as a result of swing is avoided effectively. A constructor moving to the top of the ladder does not consume a lot of physical power, so that the ladder can ascend, and the ladder ascending efficiency is high. In the process that the constructor climbs upward along the ladder, the ladder ascends automatically, so that the construction efficiency is improved. Meanwhile, the ladder is relatively low in demand on physical power and follow-up construction operation is not affected.

Description

technical field [0001] The invention relates to the technical field of ladders, in particular to a fall-proof ladder with a more stable center of gravity and convenient lifting. Background technique [0002] A ladder is a tool for daily life. The tool is made of two long and thick poles, and a cross bar suitable for climbing is crossed in the middle. It is used for climbing. Ladders are divided into lifting single ladders and lifting ladders. Chinese invention CN109184541A discloses a ladder for aerial work with anti-slip, anti-side fall and dangerous alarm. The ladder cross bar is made into a telescopic structure, which can make the ladder expand and expand laterally according to the demand, increase the lateral projection distance of the ladder, and increase the height of the ladder. The load-bearing area of ​​the center of gravity prevents the ladder from sliding sideways, but when the height of the ladder increases, the inclination angle of the ladder becomes smaller. Si...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the present invention provides an anti-fall ladder with a more stable center of gravity for easy lifting, which can be automatically reinforced when the inclination angle becomes smaller and easy to fall backwards, effectively preventing the ladder from falling backwards due to shaking. To solve the problem of overturning, after the construction personnel move to the top of the ladder, the ladder can be lifted without expending a lot of physical strength. The efficiency of raising the ladder is high, and the automatic rising of the ladder can be realized during the process of the construction personnel climbing up the ladder, which improves the construction efficiency. The efficiency is high, and at the same time, the physical strength requirements for the construction personnel are low, and it will not affect the subsequent construction operations
