The invention discloses a novel wind turbine generator set hydraulic lock pin centering device, which comprises a three-blade wind wheel, a main shaft, a gearbox, a high-speed shaft brake disc, a lock pin, a lock disc, an indicating finger and a cabin. A cabin hood is arranged on the cabin. The lock disc is fixedly arranged on the main shaft. The main shaft is connected with the cabin. The three-blade wind wheel, the main shaft, the gearbox and the high-speed shaft brake disc are sequentially connected. The indicating finger is arranged on the side surface of the front part of the cabin. A positioning hole is arranged in the lock disc and is matched with the lock pin. The wind wheel is driven to rotate through blades, manual barring is not needed, the pin and hole alignment situation is observed through the indicating finger, a hydraulic system button is pushed for locking after the pin and the hole are aligned, the structure is simple, the operating efficiency and the accuracy are high, and the labor cost is reduced.
Description
Technical field [0001] The invention relates to the technical field of wind power generating sets, and in particular to a new type of hydraulic lock pin centering device and centering method of a wind power generating set. Background technique [0002] The hydraulic lock pin is an important safety mechanism in the wind turbine. When the maintenance personnel need to enter the hub for maintenance, they must first lock the wind wheel lock. The steps to lock the wind wheel lock are: one person manually passes through the high speed shaft end The shaft brake disc is cranked. Another person observes the alignment of the lock pin and the pin hole at the lock end of the wind wheel, and the third person cooperates to operate the lock pin. When the lock pin is aligned with the pin hole, lock it. The disadvantage of this structure and operation is that since the maintenance staff of the wind turbine is usually composed of two people, an additional man is required to complete the above work...
