[0018] Please see Figure 1-3This utility model provides a technical solution: a modular assembly maintenance platform for cooling towers, including a duct 1, with a cantilever beam 4 installed on the inner wall of the duct 1. A duct door 2 is opened on one side of the duct 1. One end of a maintenance corridor bracket 51 corresponds to the position of the duct door 2. This structure facilitates personnel access to the duct door 2. A corridor railing 55 is fixedly connected to the top of the maintenance corridor bracket 51, and a maintenance platform body 56 is installed at one end of the corridor railing 55.

A corridor grid plate 53 is fixedly connected to the top of the maintenance corridor bracket 51, and one end of the corridor grid plate 53 is connected to the platform grid plate 56. 4. Fixed Connection: Both the corridor grid plate 53 and the platform grid plate 54 in this structure are FRP grid plates. The grid plates are installed below the fan foundation 3. Because the grid plates are openwork, they do not block the wind and reduce the interference of the maintenance component 5 on the cooling tower. The fan foundation 3 and the maintenance component 5 are fixedly connected to the cantilever beam 4. The maintenance component 5 of this device is made of 304 stainless steel and FRP material, which does not corrode in a humid and hot environment for a long time and has high safety. The maintenance component 5 is composed of multiple modules, which facilitates on-site installation, reduces costs, and reduces safety risks. It is also suitable for various fan foundation 3 models, with strong applicability. The cantilever beam 4 is arranged in a circular shape with equal spacing around the bottom of the platform grid plate 54. There are multiple maintenance platforms 5, and this structure ensures the overall stability of the maintenance assembly 5. The maintenance assembly 5 includes a maintenance platform bracket 52 fixed to the cantilever beam 4. The top of the maintenance platform bracket 52 is fixedly connected to the maintenance platform body 56 and the platform grid plate 54. Multiple platform grid plates 54 are provided, and the platform grid plates 54 are combined with the outer wall of the fan foundation 3 to form a polygonal structure. This structure can wrap the outer wall of the fan foundation 3, which facilitates all-round maintenance of the fan foundation 3. One end of the maintenance platform bracket 52 is connected to the maintenance corridor bracket 51, and one end of the maintenance corridor bracket 51 is connected to the air duct 1. During the civil construction of the cooling tower, embedded parts are reserved in appropriate locations for this device, including the maintenance corridor bracket. The frame 51 is welded and fixed to the embedded parts of the cooling tower frame beam. The same 8 maintenance platform brackets 52 are welded and fixed to the pre-embedded parts of the cantilever beams 4 around the fan foundation 3. The corridor grid plate 53 and the platform grid plate 54 are respectively installed on the maintenance corridor bracket 51 and the maintenance platform bracket 52. The corridor railing 55 and the maintenance platform body 56 are welded and fixed to the maintenance corridor bracket 51 and the maintenance platform bracket 52 respectively. A railing connector 57 is provided at the splice of the corridor railing 55 and the maintenance platform body 56.
