[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model below, obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments, all other embodiments obtained by the ordinary skilled in the art without creative labor based on the embodiments in the utility model belong to the protection scope of the utility model.

[0024] As Figures 4 to 5 shown, the embodiment provides a wind turbine bearing seat climbing device, which comprises arc climbing ladders 1, footboards 2 and support frames 3, the arc climbing ladders 1 are two and symmetrically installed on the left and right sides of the upper part of a bearing seat 4, the footboards 2 are installed between the two arc climbing ladders 1 through the support frames 3 and are located directly below a cabin skylight of the wind turbine.

[0025] As Figures 6 to 7 shown, the arc climbing ladder 1 comprises a climbing ladder body 101 and two climbing ladder supports 102, the climbing ladder body 101 is installed on the bearing seat 4 through the two climbing ladder supports 102, the climbing ladder support 102 is in a U-shaped structure, one end of the two parallel edges of the climbing ladder support 102 is connected with the climbing ladder body 101, and a plurality of U-shaped holes 103 for connecting with the bearing seat 4 are arranged on the middle edge.

[0026] As Figure 8 shown, the footboard 2 comprises a plurality of layers of footboards 201 arranged in sequence from bottom to top, the actual number of layers is arranged according to the distance between the footboard and the cabin cover, and two layers are taken as an example in the embodiment, the footboards 201 are connected through connecting plates 202 between every two adjacent footboards 201, and reinforcing rib plates 203 are arranged between every two adjacent footboards 201 and connecting plates 202 to prevent deformation.

[0027] The footboard 201 and the connecting plate 202 are all provided with hollow structures 204, which can reduce the weight of the footboard 2 and reduce the pressure on the supporting member, meanwhile, the hollow structure has the effect of preventing slipping and increases the safety of personnel climbing.

[0028] The edge of the footboard 201 is provided with an upturned edge structure 205, which can prevent personnel and tools from sliding off the footboard 2 and avoid the occurrence of safety accidents.

[0029] As ​ shown, the support frame 3 is composed of two U-shaped supports 301 and two cross bars 302 connected between the two U-shaped supports 301, one end of the two parallel edges of the U-shaped support 301 is connected with the arc climbing ladder 1 through a U-shaped hole 304 respectively, and the middle edge is welded with the bottom of the footboard 2.
