A device capable of automatically replacing wind turbine main shaft bearings

Abstract

The invention belongs to the technical field of wind power generator bearing replacement, and in particular relates to a device for automatically replacing a main shaft bearing of a wind power generator, which includes a climbing frame that can partially or completely surround a tower pole, a machine head disassembly mechanism, and a bearing disassembly mechanism. The head disassembly mechanism and the bearing disassembly mechanism are fixed on the climbing frame. After the climbing frame embraces the tower pole and climbs up to the working position, the head disassembly mechanism removes the machine head and the bearing disassembly mechanism Replace the old bearing with a new one, and the machine head disassembly mechanism will reset the machine head. The device of the present invention only needs to control the climbing frame to climb to the working position, then control the head dismounting mechanism to remove the machine head, then make the bearing dismounting mechanism remove the old bearing, replace it with a new bearing, and finally disassemble the machine head The mechanism installs and resets the machine head, and the whole process only needs manual remote control on the ground. The climbing and dismounting work is completely completed by the device of the present invention. The bearing disassembly and assembly is more accurate and efficient, and there is no need to consider personnel safety issues.

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
