Device capable of automatically replacing main shaft bearing of wind driven generator

Abstract

The invention belongs to the technical field of bearing replacement for wind driven generators, and particularly relates to a device capable of automatically replacing a main shaft bearing of a wind driven generator. The device comprises a climbing frame capable of partially or completely encircling a tower pole, a machine head mounting and dismounting mechanism and a bearing mounting and dismounting mechanism, wherein the machine head mounting and dismounting mechanism and the bearing mounting and dismounting mechanism are both fixed on the climbing frame, after the climbing frame encircles the tower pole to climb upwards to the working position, the machine head mounting and dismounting mechanism dismounts a machine head, the bearing mounting and dismounting mechanism dismounts an old bearing and replaces the old bearing with a new bearing, and the machine head mounting and dismounting mechanism mounts and resets the machine head. According to the device, only the climbing frame needs to be controlled to climb to the working position, then the machine head mounting and dismounting mechanism is controlled to dismount the machine head, then the bearing mounting and dismounting mechanism dismounts the old bearing and replaces the old bearing with the new bearing, finally, the machine head mounting and dismounting mechanism mounts and resets the machine head, and the whole process only needs to be manually and remotely controlled on the ground; and climbing, dismounting and mounting work is completely completed by the device, bearing dismounting and mounting are more accurate, the efficiency is higher, and the personnel safety problem does not need to be considered.

Description

technical field [0001] The invention belongs to the technical field of bearing replacement of wind power generators, and in particular relates to a device capable of automatically replacing the main shaft bearings of wind power generators. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. Wind turbines are generally composed of components such as wind rotors, generators (including devices), steering devices (tail fins), towers, speed-limiting safety mechanisms, and energy storage devices. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of the wind, which converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft, and the generator rotates to generate electricity under the drive of the wind rotor shaft. Since the wind power generator is mainly driven by the...

Problems solved by technology

[0003] In order to solve the above problems, the present invention discloses a device that can automatically replace the main shaft bearing of the wind power generator. The device only needs to control the climbing frame to climb to and fix it at the working position, and then control the head disassembly mechanism to remove the head , and then control the bearing dismounting mechanism to remove the old bearing and replace it with a new one. Finally, the nose dismounting mechanism installs the machine head back to its original position. The whole process only needs manual remote control on the ground. Climbing and The assembly and disassembly work is completely completed by the device of the present invention, the assembly and disassembly of bearings is more accurate and efficient, and there is no need to consider personnel safety issues
