Technical Field

[0001] This utility model relates to the field of elevator shaft technology, and more specifically to an adjustable, stackable, rotary elevator shaft operating platform. Background Technology

[0002] An elevator shaft operating platform is a temporary work platform specifically designed for construction, maintenance, and repair within elevator shafts. It plays a crucial role in high-rise buildings and elevator installation and maintenance. This platform not only provides workers with a safe and stable working environment but also significantly improves work efficiency and reduces the risks of working at heights.

[0003] Existing construction methods for elevator shaft operating platforms mainly fall into two categories: internal steel scaffolding support systems and standardized elevator shaft operating platforms. However, the internal steel scaffolding support system requires a large amount of scaffolding for erection, and the erection and dismantling process is relatively complex, consuming significant time and manpower. Furthermore, since the support system for each floor needs to be erected separately, the transition time between floors is also lengthy. If the size of the elevator shaft or the floor height changes, it may be necessary to redesign and remanufacture the operating platform, further increasing construction costs and time.

[0004] Therefore, how to provide an adjustable, stackable, reusable elevator shaft operating platform that can be moved between multiple floors and fixed in elevator shafts of various sizes is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
