Description

Auxiliary indoor high-altitude operation construction trolley

Technical Field

The invention relates to the field of indoor lifting equipment, in particular to a construction trolley for assisting indoor high-altitude operation.

Background

The work kind of job site is various, and the field operation dust is big, causes very big injury to the human body easily, and more serious is when there are debris such as little stone in the ground, and the chassis can incline, and this leads to the working face also to incline, increases the construction risk. Each kind of work all needs to use many different tools, leads to the instrument type more and more, and diversified instrument leads to the job site more and more chaotic, and the instrument is difficult and easy to manage. Secondly, the climbing machine with autonomous movement on the market is high in quality and not easy to move, and most of the robots for indoor auxiliary construction only assist one operation, and the whole construction process is not considered. Therefore, the decoration high-altitude operation tool which is light, flexible, high in safety and rich in functions and is really applied to indoor decoration is not provided in China for a while. Because the problems are not solved, the existing indoor decorating workers in China generally adopt a self-made ladder made of local materials temporarily or a common herringbone ladder, work for a long time on the ladder, the burden on the body of the worker is large, the working efficiency is low, small accidents occur frequently, and certain risks exist although the indoor height is low.

Accordingly, further improvements and improvements are needed in the art.
