[0011] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, an indirect connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0012] like Figure 1-2 As shown, a large-scale hydropower station stator cleaning and maintenance assembled platform includes: a platform component 1, a scaffolding fastener 2, and a tensioning belt 3. The platform component 1 is a hollow box frame structure composed of a plurality of scaffolding pipes (diameter = 48mm, thickness = 3.5mm) and a steel plate (a patterned steel plate with a thickness of 5mm). A scaffolding fastener 2 is connected between two adjacent platform components 1. A plurality of platform components 1 and scaffolding fasteners 2 are connected to form a platform main structure. The platform main structure is an annular structure. The tensioning belt 3 is located at the top of the platform main structure. One end of the tensioning belt 3 is fixedly connected to the platform component 1, and the other end of the tensioning belt 3 is fixedly connected to the annular wall of the hydropower station stator.

[0013] Preferably, three platforms are arranged from top to bottom in the platform assembly 1, ladders are arranged between the three platforms, and a protective net, a skirting board and a foot pedal are arranged on the platform assembly 1.

[0014] When in use, several platform components 1 are hoisted into the machine pit for assembly in turn. When hoisting in, the stator is properly protected to prevent it from being hit. Then, the platform components 1 are connected with scaffolding fasteners 2 to form the platform main structure. After the assembly is completed, a protective net is hung on the platform components 1. Finally, the tensioning belt 3 is used to fix the platform main structure and the annular wall of the power station stator firmly.

[0015] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments and various changes can be made thereto within the knowledge scope of those skilled in the art.
