High-altitude operation ladder capable of preventing slip and sideway falling and giving alarm in dangerous case

Abstract

The invention provides a high-altitude operation ladder capable of preventing slip and sideway falling and giving an alarm in a dangerous case. The high-altitude operation ladder comprises two vertical ladder poles, the two vertical ladder poles are connected by a plurality of parallel cross ladder rods, and every cross ladder rod is a telescopic structure capable of changing the width of the ladder in order to increase the gravity center bearing area of the ladder, so the ladder can be transversely telescoped and widened as needed to increase the transverse projection distance of the ladder,increase the gravity center bearing area of the ladder and prevent the sideway falling of the ladder; a rotary wedge-shaped anti-slip pad for increasing the friction force between the ladder and the ground to prevent the ladder from sliding downwards is arranged at the lower end of every vertical ladder pole, so the friction coefficient with the ground is increased, and the ladder is effectively prevented from sliding downward; and a level gauge warning device capable of detecting the lateral and front-back tilt angle of the ladder and giving an alarm is arranged in the lower inner chamber ofone of the vertical ladder poles, and can give the alarm when the lateral tilt angle of the ladder is more than or equal to 15 DEG and the front-back tilt angle of the ladder is less than or equal to60 DEG in order to timely provide a safety warning for construction personnel in time.

Description

technical field [0001] The invention belongs to the technical field of ladders, and in particular relates to a ladder for aerial work with anti-slip, anti-side fall and danger alarm. Background technique [0002] At present, various ladders are often used in work and life in the construction industry, communication industry, advertising industry, and home needs of units. Due to working at a height of more than three meters, ladders often slip and fall sideways. It caused great harm to the construction workers, caused the injured to suffer great pain, and the family unit suffered economic losses that should have been avoided, and wasted public medical resources. Currently on the market, anti-slip measures for ladders are only adding plastics, rubber sheets, etc. on the crossbars and the roots of the vertical poles, but they still cannot effectively solve the problems of ladders slipping and falling sideways. For this reason, designing a kind of anti-slip and anti-side fall l...
