Rear rack assembly of wind generating set

Abstract

The invention discloses a rear rack assembly in a wind generating set. The rear rack assembly comprises a rear rack welding part and a rear rack accessory. The rear rack seaming comprises a main rackconnecting plate, an upper panel, a lower panel, a left side plate, a right side plate, a generator front support seaming, a generator rear support seaming, a cantilever crane mounting support seaming, a cabin bracket mounting plate, a cabin cabinet mounting bracket, a left side walking channel mounting bracket, a right side walking channel mounting bracket and the like; and the rear rack accessory comprises a generator rotor outgoing cable, a rotor outgoing cable mounting rack, a generator stator outgoing cable, a stator outgoing cable mounting rack, a generator auxiliary junction box outgoing cable mounting rack, a gear box cooling system pipeline and a grid type cable bridge. The rear rack assembly not only is used for supporting key components such as a generator, a cabin control cabinet I, a cabin control cabinet II, a cabin bracket and a walking channel cover plate, but also is used for fixing components such as an outgoing cable and a cable mounting frame, and has the characteristics of simple structure and convenience in mounting.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a rear frame assembly of a wind power generating set. Background technique [0002] The rear frame assembly is one of the most important supporting components inside the wind turbine nacelle, and its structural strength requirements are very high. It is not only used to support key components such as generators, nacelle cabinets, and nacelle brackets, but also used to fix the generator stator. Outlet cables, generator rotor outlet cables, generator auxiliary junction box cables, gearbox water cooling system pipelines, etc. [0003] At present, the structure of the rear frame used in the nacelle of the megawatt-class wind turbine, such as the rear frame disclosed in the invention patent application with the application publication number CN106224183A, includes a main frame, a structural beam, a middle joist and Bracket, the main frame is a rectangular fr...

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
