New tool for dismantling wind power pitch cylinder

Abstract

The invention discloses a novel tool for dismantling a wind power pitch oil cylinder, comprising a fixing mechanism and a driving mechanism. The fixing mechanism is used to be fixedly connected to the cylinder head of the wind power pitch oil cylinder, and the fixing mechanism is provided with a same part as the cylinder head. The power receiving end of the shaft; the power receiving end can receive the driving of the driving mechanism to rotate so as to realize the disassembly and installation of the cylinder head. The novel tool for dismantling the wind turbine pitch oil cylinder provided by the present invention has a split structure for the drive mechanism and the power receiving end. During the disassembly and installation of the cylinder head, there is no need to disassemble the oil pipe and other structures, so as to improve the replacement of the sealing ring and the guide ring. At the same time, auxiliary tools such as ratchet wrenches, electric wrenches, hydraulic wrenches, etc. can be used to reduce the physical consumption of operators and improve the efficiency of cylinder head disassembly and installation.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a novel tool for dismantling a wind power variable pitch oil cylinder. Background technique [0002] The wind power pitch system is a wind turbine blade adjustment device. When the wind is strong, the angle of attack of the blade is reduced by the adjustment device; when the wind is small, the angle of attack of the blade is increased through the adjustment device. Adjust the pitch angle and control the absorbed mechanical energy, on the one hand to ensure the maximum energy (corresponding to the rated power), and at the same time to reduce the impact of the wind on the wind turbine. The oil cylinder is an indispensable equipment in the wind power pitch system. During the operation of the wind power pitch system, due to the uneven radial force of the cylinder head on the piston rod, the seal of the cylinder head is subjected to unilateral force for a long time, whic...

AI Technical Summary

Problems solved by technology

[0005] First, when disassembling or installing the cylinder head in the fan hub, since there are many oil pipes arranged around the pitch cylinder, the oil pipes block the rotation of the drive rod, so the oil pipes around the oil cylinder need to be disassembled, and the sealing ring and guide ring After the replacement, the oil pipes need to be reconnected and installed, which increases the workload of the operator and affects the efficiency of the replacement

[0006] Second, when using this removal tool to disassemble the cylinder head, tools such as ratchet wrench, electric wrench, and hydraulic wrench cannot be used to assist, which consumes a lot of physical strength of the operator, making the disassembly or installation of the cylinder head inefficient. The space is narrow, the operating space is small, and the replacement time of the prior art cylinder head is more than 5 hours
