Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building decoration equipment, in particular to a building decoration platform. BACKGROUND

[0002] The small lifting platform for building decoration is used to provide a stable and reliable working plane in the air for construction personnel, replacing the traditional operation mode which relies on scaffolding and ladders and has high risk. It can not only safely bear the operating personnel, but also synchronously transport necessary materials such as paint, tools and tiles, greatly reducing the labor intensity and time consumption of frequent loading and unloading. The structure of such equipment generally consists of a base, a lifting mechanism, a working platform and a control system. The base provides stable support, the lifting mechanism realizes stable lifting of the platform, the working platform is equipped with safety guardrails to ensure operation safety, and the control system facilitates the accurate control of the platform by the operating personnel. When in use, the platform is placed on a flat and solid ground, and the lifting mechanism slowly lifts the working platform to the appropriate height through the control system to avoid overloading and violent shaking. After the work is completed, it is slowly lowered to the ground to ensure the safety of personnel getting off the platform and closing the equipment. As disclosed in the authorized announcement No. CN216690284U, a simple lifting platform for building decoration includes a base, side plates, sliding blocks, a platform, connecting plates, two supports, two handrails, multiple moving devices, multiple supporting devices, a driving device and a transmission device. The upper end of the base is installed with side plates, the side ends of the side plates are provided with sliding rail grooves, the sliding blocks slide in the sliding rail grooves, and the platform is installed at the side end of the sliding block through the connecting plate. The tools used for building decoration are placed on the platform. The equipment is conveniently moved through the multiple moving devices at the lower end of the base. After the equipment is moved to the position, it is stabilized through the multiple supporting devices. The worker stands on the upper end of the platform to perform decoration work. It can be seen that the above-mentioned equipment is still mainly used to assist the workers to perform indoor or outdoor lifting work. Specifically, for wall painting and wall polishing work, the workers still need to manually adjust the position according to the actual work steps. The wall treatment of a large space needs to repeatedly lift and move the platform, and a large amount of working hours is invested, which leads to the difficulty in compressing the project cycle. Even if the lifting platform is used, the worker still needs to work for a long time with his head up and arms raised, and is always exposed to the environment of dust (when polishing) and chemical volatiles (in paint), so the long-term health risk still exists. SUMMARY

After the operation mode is selected, the distance between the spray pipe assembly or the dual-disc synchronous grinder and the wall surface is further controlled by the lead screw linear feed module.
