Description

Technical Field

[0001] The utility model relates to the field of dismantling tools, in particular to a dismantling tool for a variable pitch oil cylinder. Background Art

[0002] The wind turbine pitch system is a blade adjustment device for wind turbines. When the wind is strong, the blade angle of attack is reduced through the adjustment device; when the wind is weak, the blade angle of attack is increased through the adjustment device. In this way, the pitch angle is adjusted at any time according to the change of wind speed to control the absorbed mechanical energy, on the one hand to ensure the maximum energy (corresponding to the rated power) and at the same time reduce the impact of wind on the wind turbine. The oil cylinder is an indispensable device in the wind turbine pitch system. During the operation of the wind turbine pitch system, the cylinder head is subjected to uneven radial force of the piston rod, and the cylinder head seal is subjected to long-term unilateral force, which is easy to cause excessive wear and oil leakage in the cylinder, and then the cylinder needs to be disassembled.

[0003] The disassembly portion is usually provided with a bolt with a hexagonal groove in the end. If the existing hexagonal wrench is rotated, it cannot be rotated continuously due to the obstruction of the cylinder body, and then it needs to be reciprocated and rotated, which reduces the disassembly efficiency.

[0004] In order to solve the above problems, a pitch cylinder removal tool is proposed in the present application. Utility Model Content
