[0049] The working principle and use process of the present invention are as follows: when constructing the lower end of the inner side of the wind turbine tower, the end of the support beam 2 can be connected to the inner wall of the wind turbine tower through a sling, and the support plate 3 can be laid between two adjacent support beams 2, and an entrance and exit 6 can be left for construction personnel to enter and exit. The support plate 3 and the fixed column 401 can be used to support the construction personnel and tools. When the upper end of the inner side of the wind turbine tower is used, due to the reduction of the inner diameter of the wind turbine tower, the oblique support 405 can be removed from between the fixed column 401 and the guardrail frame 403, and the guardrail frame 403 can be folded toward the fixed column 401. At this time, the second pin can be inserted into the inner side of the first ear plate 406 and the second ear plate 407 to lock the folded state, thereby reducing the outer diameter of the construction platform, and then through The sling can suspend and connect the support beam 2 to the inner wall of the wind turbine tower. When entering and exiting the platform, the construction workers can push and pull the adjustment handle on the slider 7021 to drive it to slide, so that the block at one end of the slider 7021 can be withdrawn from the inner side of the slot 7023. At this time, the first guardrail bar 702, the second guardrail bar 704 and the telescopic rod 703 can be rotated around the fixed frame 701 to release the protection of the guardrail door 7 so that the construction workers can enter and exit the platform. At the same time, the first guardrail bar 702 can be moved up and down along the fixed frame 701 to adjust the protection area. After adjustment, the block is pushed by the spring 7022 to enter the inner side of another slot 7023, and the first guardrail bar 702 and the fixed frame 701 can be quickly locked to form protection for the entrance and exit 6.
