The platform also includes a limit ring 4, a sliding adjustment mechanism 5 and a bearing mechanism 6. The limit ring 4 is arranged on the upper part of the support rod 2, and the sliding adjustment mechanism 5 is connected to the outer walls of the support ring 1 and the limit ring 4, and moves along the circumferential direction of the support ring 1 and the limit ring 4. The bearing mechanism 6 is connected to the bottom of the sliding adjustment mechanism 5 to provide a working area.

[0018] like Figure 1 and Figure 4 As shown, in order to achieve comprehensive maintenance of the workers, the bearing mechanism 6 is moved along the circumferential direction of the limiting ring 4 and the supporting ring 1, the sliding adjustment mechanism 5 includes an adjusting rod 7, a limiting wheel 8, a supporting wheel 9 and a supporting plate 10. The adjusting rod 7 is arranged in an inverted J shape, and the limiting wheel 8 rotates on the end face of the upper bending part of the adjusting rod 7, the limiting wheel 8 rotates parallel to the ground and contacts the inner wall of the limiting ring 4, the supporting wheel 9 is rotatably connected to the side wall of the adjusting rod 7 perpendicular to the ground, the supporting wheel 9 is symmetrically arranged up and down, the supporting wheel 9 is clamped on the upper and lower side walls of the supporting ring 1, the supporting plate 10 is arranged on the lower end face of the adjusting rod 7, and the upper part of the adjusting rod 7 is bent to support the inner side wall of the limiting ring 4 through the limiting wheel 8. The symmetrical supporting wheels 9 are clamped on the upper and lower sides of the supporting ring 1 to provide supporting force for the circular movement of the adjusting rod 7 to prevent the adjusting rod 7 from being tilted due to force below, and the supporting plate 10 is used to support the bearing mechanism 6.

[0019] like Figure 1 , Figure 3-5 As shown, in order to provide a working area for workers and realize the up and down movement adjustment of the carrying plate 12, the carrying mechanism 6 includes a sleeve 11, a carrying plate 12 and a cylinder 13. The carrying plate 12 is slidably arranged on the outer wall of the adjusting rod 7 perpendicular to the ground. The sleeve 11 is fixedly connected to the center of the upper part of the carrying plate 12. The sleeve 11 slides synchronously with the carrying plate 12 along the direction perpendicular to the ground of the adjusting rod 7. The cylinder 13 is arranged on the upper part of the support plate 10. The telescopic end of the cylinder 13 is connected to the bottom wall of the carrying plate 12. The cylinder 13 is symmetrically arranged with the adjusting rod 7 as the center. The side wall of the carrying plate 12 is provided with a sliding hole 14. An elastic support component 15 is slidably connected in the sliding hole 14. The carrying plate 12 is connected to the sleeve 11 and slides on the outer wall of the adjusting rod 7. The carrying plate 12 is supported by the cylinder 13 on the upper part of the support plate 10 to realize the up and down movement adjustment of the carrying plate 12.

[0020] At the same time, in order to increase the stability of the bearing plate 12 and further improve the lateral supporting force of the bearing plate 12, the elastic supporting assembly 15 includes a U-shaped rod 16 and a stopper 17.

The operator climbs the ladder and steps on the bearing mechanism 6. When maintaining the inner wall of the tower, the operator can manually contact the limit ring 4 or the support ring 1 to push the adjustment rod 7 to move. The limit wheel 8 supports the inner wall of the limit ring 4. The symmetrical support wheels 9 are clamped on the upper and lower sides of the support ring 1, supporting the circular movement of the adjustment rod 7 while increasing the oblique support force of the adjustment rod 7 to avoid the adjustment rod 7 from tilting under force. The elastic support assembly 15 extending from the side wall of the bearing plate 12 is used to support the bearing plate 12 horizontally to avoid the bearing plate 12 from tilting under force, thereby increasing the stability of the bearing plate 12.

[0022] The bearing plate 12 can not only make circular motion along the circumferential direction of the support ring 1 and the limit ring 4, but also can be adjusted up and down by the cylinder 13 between the support plate 10 and the bearing plate 12, so as to realize all-round maintenance inspection and improve the maintenance efficiency of workers.
