The invention discloses an impeller locking device and wind power equipment, and relates to the technical field of wind power generation. The impeller locking device comprises a locking pin, a lockingdisc and a transition sleeve, wherein the transition sleeve is arranged on the locking disc; the locking pin is detachably connected with the transition sleeve in an inserted mode; the locking pin isprovided with a locking pin working plane; the transition sleeve is provided with a transition working plane matched with the locking pin working plane; and the transition sleeve can rotate relativeto the locking disc, so that when the locking pin is connected with the transition sleeve in an inserted mode, the locking pin working plane makes surface contact with the transition sleeve working plane. The wind power equipment comprises the impeller locking device. According to the impeller locking device and the wind power equipment provided by the invention, the technical problem that the crushing phenomenon is likely to occur since local extrusion stress at the contact position is likely to be too large when the locking pin locks the locking disc in the prior art is solved.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to an impeller locking device and wind power equipment. Background technique [0002] When the fan fails or requires maintenance personnel to enter the engine room or hub for inspection, the impeller of the fan will retract the propeller first, and then the brake system will start to work. When the impeller basically stops rotating, insert the locking pin into the locking hole of the locking disc. Lock the impeller to ensure the safety of maintenance personnel. [0003] In the prior art, when the impeller is stopped for maintenance, the locking pin is mostly in line contact with the locking disc, which may easily lead to excessive local extrusion stress at the contact point, and then prone to crushing. Contents of the invention [0004] The purpose of the present invention is to provide an impeller locking device and wind power equipment to solve the problem of exce...
