A wind wheel locking device

Abstract

The invention provides a wind wheel locking device. The wind wheel locking device comprises a first lock body, a second lock body, a hinge pin and a driving structure, wherein the first lock body is suitable for being mounted on a wind wheel, synchronously rotates with the wind wheel and is provided with a locking hole; the second lock body is suitable for being fixedly arranged on a bracket and is provided with a lock hole, and the lock hole is provided with a first opening facing the wind wheel; the hinge pin is mounted in the lock hole, can axially move along the lock hole under the action of external force, and is provided with a first position and a second position; the first position is inserted into the locking hole through the first opening so as to lock the wind wheel, and the second position is pulled out of the locking hole and withdrawn into the lock hole through the first opening so as to unlock the wind wheel; and the driving structure is used for driving the hinge pin to switch between the first position and the second position. The wind wheel locking device further comprises an oil delivery structure used for supplying lubricating oil to a clearance between the hinge pin and the inner wall of the lock hole. When lubricating oil needs to be supplied to the wind wheel locking device, oil can be supplied through only an oil supply structure without pulling out the hinge pin, so that operation is convenient.

Description

technical field [0001] The invention relates to the technical field of a wind wheel fixing device for wind power generation equipment, in particular to a wind wheel locking device. Background technique [0002] With the increasingly serious problem of environmental pollution, people hope to have more clean energy, and wind energy is a clean and renewable energy with huge reserves. In order to make full use of this resource, people began to use wind power generators to wind power generation. Wind turbines need to be overhauled after running for a certain period of time. When overhauling some specific locations, in order to ensure the personal safety of maintenance personnel, it is necessary to lock the wind rotors. Therefore, each wind turbine is equipped with a wind rotor locking device. [0003] Wind wheel locking devices in the prior art are generally divided into two types: hydraulic type and manual mechanical type. Among them, the hydraulic wind wheel locking device mu...

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the technical defect that the manual mechanical locking device in the prior art cannot design the oil filling hole from the outside. A wind wheel locking device that can add lubricating oil to the inner wall of the lockhole with various thicknesses of the lockhole without pulling out the pin shaft, so it is easy to operate
