[0002] At present, mobile operating platforms are commonly used and indispensable construction facilities at construction sites. When carrying out various masonry, decoration and painting operations with a height of less than 5m, the construction site will give priority to setting up mobile operating platforms for construction. There are two main types of mobile platforms commonly used on construction sites. One is a detachable operating platform commonly used for decoration, and the other is a simple scaffolding platform built with steel pipes. Both can be easily assembled and disassembled on site and can be reused.

[0003] However, there are two aspects of influence when the traditional mobile operating platform is used for masonry, plastering and painting in the building: First, due to safety requirements, the upper guardrail must be at least 1.2m. When the construction is completed in this area and the next area is moved to, the guardrail will conflict with the beams in the building because it is too high. At this time, the guardrail needs to be removed to reach the next construction area for construction. Therefore, when carrying out construction work in the building, the guardrail needs to be frequently disassembled and installed to enable the operating platform to move in the building. Second, the construction space at the bottom of the beam is very small when the operating platform meets the requirements of the bottom decoration construction, which will bring inconvenience to the construction of on-site workers.
