Description

technical field [0001] The invention belongs to the technical field of engineering construction, and in particular relates to a safety anti-drop device for steel structure engineering construction and a use method thereof. Background technique [0002] Engineering construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. In the process of high-altitude operations such as high-rise building construction, lifting platforms need to be used for operations, but the structure of the anti-falling device of the existing lifting platforms is not suitable for use. If it is too stable, the expected anti-falling ef...

Problems solved by technology

[0004] The anti-falling safety device disclosed in the above-mentioned patent achieves the purpose of anti-falling by squeezing the guide rail by the brake wheel assembly to slow down the falling speed, but the device still has many shortcomings. It cannot brake in time, and there are safety risks. The anti-falling effect is not good. prone to accidents
