The invention discloses special equipment and a method for replacing parts of a wind generator. The special equipment comprises a working platform, a locking device, a hoisting mechanism and a lifting device, wherein the working platform comprises a first part and a second part which are detachably connected with each other; an opening encircling a tower barrel of the wind generator is formed in the working platform; the locking device can be telescopically mounted in the opening of the working platform and is used for supporting the tower barrel; the hoisting mechanism is mounted on the working platform, and comprises a truss, a beam supported by the truss, a sliding trolley mounted on the beam and a hoisting hook; the lifting device is connected between the working platform and a fixed acting point and is used for lifting the special equipment; the lower end of the truss is hinged with the working platform; the hoisting mechanism further comprises a roll-over hydraulic cylinder; and the roll-over hydraulic cylinder and the hoisting mechanism can be rolled over. The wind generator can be lifted by utilizing the special equipment, so that the dependence on large lifting devices is reduced. Therefore, the cost for replacing the parts of the wind generator is lowered.
Description
technical field [0001] The invention relates to the field of wind power generators, more specifically, to a special device for replacing parts of a wind power generator and a method for replacing parts of a wind power generator using the special device. Background technique [0002] The wind generator has an impeller that converts the kinetic energy of the wind into mechanical energy, and the converted mechanical energy can be further converted into electrical energy by the generator. Wind turbines can be applied to offshore wind farms and onshore wind farms. Large offshore wind turbines are usually installed in marine environments, such as figure 1 As shown, it mainly includes a foundation 1, a tower 2, a nacelle 3, a generator 4, blades 5, etc., wherein the lower parts of the foundation 1 and the tower 2 are below sea level. [0003] Large-scale offshore wind turbines need to rely on large hoisting ships and other equipment to replace large parts of wind turbines. Gener...
