Problems solved by technology

The disadvantage of this solution is: the deformation of the two independent positioning connecting plates is relatively large during the welding process. Before welding, multiple reinforcing ribs need to be spot welded to prevent deformation. Welding deformation, which increases the auxiliary man-hours of welding and reduces the working efficiency of welding
During the machining process of the two independent positioning connecting plates, there is machining stress, because the machining of the two positioning connecting plates is two processes, which may lead to inconsistent machining deformation, resulting in deviations in size, Affect the final installation effect

specific Embodiment 1

[0043] Such as figure 1 , figure 2 with image 3 As shown, the rear frame assembly of the wind turbine includes two parts, the rear frame welding 1 and the rear frame attachment 2. The rear frame welding 1 is a weldment, including the main frame connecting plate 101, the upper panel 102, Generator front support welding 103, cantilever crane installation support welding 104, generator rear support welding 105, engine room support mounting plate 106, right side plate 107, lower panel 108, left side plate 109, cabin cabinet installation Bracket 110, left side walking channel mounting bracket 111 and right side walking channel mounting bracket 112. The main frame connecting plate 101 is fixed on the main frame for connecting the main frame; the upper panel 102, the lower panel 108, the left side plate 109 and the right side plate 107 are welded with the main frame connecting plate 101; the front support of the generator is welded 103 is welded with the generator rear support 1...

specific Embodiment 2

[0051] Such as figure 1 , figure 2 , image 3 As shown, the rear rack attachment 2 includes the generator rotor outgoing cable 201, the generator rotor outgoing cable mounting frame 202, the generator stator outgoing cable 203, the generator stator outgoing cable mounting frame 204, and the generator auxiliary junction box outgoing cable mounting frame 205, gear box cooling system pipeline 206, mesh cable bridge 207.

[0052] Attachment 2 of the rear frame is equipped with generator rotor outgoing cable 201, rotor cable clamp assembly and generator rotor outgoing cable mounting frame 202. After the outgoing cable is drawn out from the generator, it can be directly fixed on the corresponding mounting frame. Simple and convenient for follow-up wind field maintenance.

[0053] The generator stator outlet cable 203, stator cable clamp assembly and stator outlet cable installation frame 204 are arranged on the rear frame accessory 2. After the outlet cable is drawn out from the...

specific Embodiment 3

[0058] Compared with the specific embodiment 1 of the rear frame assembly of the wind power generator of the present invention, the only difference is: the generator rotor outlet cable 201, the rotor outlet cable mounting frame 202, and the generator stator outlet cable 203 in the above embodiment 1 And the position setting of the stator outlet cable mounting frame 204 can be set on the other side according to the actual situation.

[0059] In summary, the present invention provides a rear frame assembly in a wind power generating set, including rear frame welding and rear frame accessories; the rear frame welding includes a main frame connecting plate, an upper panel, a lower panel, Left side panel, right side panel, welding of front support of generator, welding of rear support of generator, welding of installation support of cantilever crane, installation plate of engine room bracket, installation bracket of engine room cabinet, installation bracket of left aisle, right Sid...
