An electric device for locking the hub of a wind power generating set

Abstract

The invention discloses an electric device for locking the hub of a wind power generating set, which comprises a casing, one end of the casing is fixedly mounted on a mounting flange, the other end is mounted with an end cover, and the inside of the casing is fixedly mounted with a mounting plate, a base and Speed ​​regulating device; a motor and a reducer are fixedly installed on the side of the mounting plate, the output shaft of the motor penetrates the mounting plate and is connected to the driving wheel, the output shaft of the reducer penetrates the mounting plate and is connected to the driven wheel, and the driving wheel and the driven wheel are connected by a transmission The belt is connected, and the other end of the driven wheel is rotationally connected with a handle, and the handle runs through the end cover. The invention adopts the lead screw push rod to cooperate with the reducer device to realize the locking and riveting of the wheel hub, and controls the alternating current motor through the operation button to carry out forward and reverse control, and the motor drives the reducer to work through belt transmission. After the reduction and efficiency increase of the reducer, the lead screw push rod is controlled to perform telescopic movement to achieve the purpose of locking the hub and solve the defects of the original operating mechanism such as difficult operation and many mechanical failures.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to an electric device for locking the hub of a wind turbine. Background technique [0002] The wheel hub locking mechanism commonly used in the existing wind turbines is a worm-type mechanical structure, which locks the wheel hub by manually rotating the lead screw bolt by the maintenance personnel during work; usually two or more personnel are required to cooperate with each other to complete, which wastes manpower. At the same time, improper matching may damage the spindle locking disc. [0003] During long-term use, the rotating bolts of the original mechanism are affected by environmental factors such as external humidity and oxidation, and the rotating bolts will have problems such as "rusting" and laborious rotation, and the operation is time-consuming and laborious. After the stop button, the impeller lock is not locked and directly enters the hub, which leads ...
