In this embodiment, the mounting bracket 1 can be clamped and fixed to the tower of the wind turbine. The connection between the mounting bracket 1 and the tower can be a threaded connection, a snap connection or a magnetic connection, etc. to facilitate assembly and disassembly. In this way, after the installation frame 1 is raised to the required height, the installation frame 1 can be fixed on the tower, and the installation frame 1 can be removed after the maintenance work is completed. It can be understood that the plurality of extension pieces 21 are sleeved in sequence, and one end of the innermost extension piece 21 is connected to the mounting bracket 1, then the platform component 4 is installed on the outermost extension piece 21. When the plurality of extension pieces 21 slide relative to each other, , the outermost extension piece 21 gradually moves away from the innermost extension piece 21 to move the platform assembly 4 to the blade tip. Optionally, two adjacent extension pieces 21 can slide relative to each other through rollers, balls, or sliders, which are not limited here.

For example, the driving member 31 can be provided on the outermost extension member 21 and at an end of the extension member 21 away from the mounting bracket 1 . One end of the driving rope 33 is connected to the output end of the driving member 31 , and the other end of the driving rope 33 is connected to the output end of the driving member 31 . One end is wound around a plurality of extension members 21 in sequence. It can be understood that the driving rope 33 is connected in sequence from the outermost extending member 21 to the innermost extending member 21.

The driving member 31 may be a motor or a rotary cylinder or other mechanism for winding up the driving rope 33, which is not limited here.

The maintenance platform 100 provided by the present invention is installed on the tower of the wind turbine through the mounting frame 1 for lifting and lowering, so as to facilitate lifting the platform assembly 4 to the required maintenance height. The telescopic arm assembly 2 is provided on the mounting frame 1. The telescopic arm assembly 2 includes a plurality of extension pieces 21 that are sleeved in sequence. Two adjacent extension pieces 21 are slidingly connected, so that the plurality of extension pieces 21 slide relative to each other, so that the telescopic arm assembly 2 Overall elongation. The platform assembly 4 is arranged on the outermost extension member 21. When the telescopic arm assembly 2 is extended as a whole, the platform assembly 4 can move to the blade tip, making it convenient for maintenance personnel to stand on the platform assembly 4 to inspect the blades. The driving rope 33 is spirally wound around the plurality of extending members 21 in sequence. When the driving member 31 pulls the driving rope 33, the driving rope 33 spirally contracts, so that the plurality of extending members 21 slide relative to each other, thereby achieving the overall extension of the telescopic arm assembly 2. In this way, it is ensured that the platform assembly 4 can be moved to the blade tip, making it easy to inspect the blade tip.

According to an access platform 100 provided by the present invention, each extension member 21 has a proximal end adjacent to the mounting bracket 1 and a distal end far away from the mounting bracket 1. Among the two adjacent extending members 21, the driving rope 33 connects the proximal end of one extending member 21 and the distal end of the other extending member 21 in turn. The driving member 31 pulls the driving rope 33 to drive one extending member 21 to extend relative to the other. The members 21 slide so that the proximal end of one extension member 21 and the distal end of the other extension member 21 are close to each other.

In this embodiment, the extension member 21 is elongated and has sufficient length to extend to the blade tip. It can be understood that the end of the extension member 21 adjacent to the mounting frame 1 is the proximal end, and the end far away from the mounting frame 1 is the distal end. When the driving member 31 is not driven, the proximal ends of each extension member 21 are arranged adjacent to each other. . As shown in FIG. 3 , two adjacent extension members 21 are respectively a first extension member 211 and a second extension member 212 . The second extension member 212 is closer to the mounting bracket 1 than the first extension member 211 . The proximal end 2111 of the first extension member 211 and the distal end 2121 of the second extension member 212 are connected through the driving rope 33. When the driving rope 33 is pulled and rolled up, the first extension member 211 slides in the direction away from the mounting bracket 1. The proximal end 2111 of the first extension member 211 gradually approaches the distal end 2121 of the second extension member 212. That is to say, the distal end 2112 of the first extension member 211 gradually moves away from the distal end 2121 of the second extension member 212 to achieve a telescopic arm.
