Description

Wind turbine generator system becomes supplementary device of changing of oar spare part

Technical Field

The invention relates to the technical field of wind turbine generators, in particular to a variable-pitch part auxiliary replacing device of a wind turbine generator.

Background

The wind power generation set is a device for converting the kinetic energy of wind into electric energy, and converts the kinetic energy of wind into mechanical kinetic energy and then into electric kinetic energy, namely wind power generation, the principle of wind power generation is that wind power drives windmill blades to rotate, and the rotating speed is increased through a speed increaser to promote the generator to generate electricity, according to the current windmill technology, the breeze speed of about three meters per second can be used for generating electricity, the wind power generation is forming a stream of hot tide in the world, because the wind power generation does not need to use fuel and can not generate radiation or air pollution, a device required by the wind power generation is called as a wind power generation set, the wind power generation set can be mainly divided into three parts of a wind wheel, a generator and a tower, and a large wind power station basically has no tail rudder, and generally only a small wind power station comprises a household type and can have the tail rudder, the parts in the wind turbine generator need to be disassembled when being replaced, and partial parts are moved after being disassembled, but a worker easily has the situation of not being easy to move when moving partial parts, generally, people think that the power of wind power generation is completely determined by the power of the wind power generator, and always want to choose a larger wind power generator, which is incorrect, the existing wind power generator only charges a storage battery, but stores electric energy by the storage battery, the size of the electric power finally used by people is more closely related to the size of the storage battery, the size of the power mainly depends on the size of air volume, not only the size of the head power, but also the parts need to be moved when being assembled and disassembled, the partial parts are easy to fall off when being moved, so that the parts are damaged, the partial parts have large volumes, the swinging of the parts is more laborious, and the worker is easy to smash when being moved, the part collision is easily caused when the part is lifted, so that the part in the lifting equipment is bent or broken, the working efficiency of the equipment is reduced, the replacement speed of the part is influenced, the part is easily moved due to error touch after being detached, and the part is lost when being subsequently installed.

In summary, the parts need to be moved during the assembling and disassembling process, and some parts are easy to fall off during the moving process, so that the parts are damaged, the speed of replacing the parts is affected, and the parts are easy to move due to error touch after being disassembled, so that the parts are easy to be lost during the subsequent installation.

referring to fig. 1-8, the present invention provides a technical solution based on embodiment 1: a use method of a variable-pitch part auxiliary replacement device of a wind turbine generator set comprises the following steps: the equipment is installed by using the base 3, the side supporting plate 2 contacts the supporting arm 1 on the base 3, so that the equipment is installed close to the equipment of the part to be replaced, the lifting hook 5 is close to the equipment along with the descending of the lifter 7 on the rotating column 6, and the part is hooked by the lifting hook 5;

step two: after the component is hooked, the lifter 7 lifts the component, the transmission frame 452 rotates along with the driving motor to drive the moving column 454 to rotate, the rotation of the moving column 454 drives the displacement shell 451 to move on the horizontal supporting plate 46, so that the hooking position of the component is adjusted, and the linkage rod in the linkage frame 95 rotates along with the displacement shell 451;

step three: when the rotary column 6 is installed, the rotary column 6 contacts the linkage frame 95, so that the arc-shaped clamp plate 93 moves to the locking block 94 under the pressure of the rotary column 6, and the auxiliary supporting frame 91 and the clamping plate 92 are connected inside the displacement shell 451 to support the linkage frame 95, so that the clamping cavity formed by the arc-shaped clamp plate 93 and the installation opening of the displacement shell 451 are kept to be oppositely arranged;

step four: the guide rod 444 is arranged between the displacement shell 451 and the lifter 7, so that the displacement shell 451 contacts the assembly plate 441 when sliding, and the abutting plate 442 cooperates with the abutting plate 83 to tightly push the support arm 1, so that the contact post 82 contacts the assembly plate 441 with the buffer post 84, and the contact post 82 is transmitted to the contact post 82 by shaking along with the movement of the displacement shell 451, so that the contact post 82 rotates on the abutting plate 83 through the rotating base 81;

step five: when the lifting part of the lifter 7 stops, the lifter 42 drives the bearing shell 434 to move on the screw 41 to the contact part, the bearing shell 434 rotates on the lifter 42 through the clamping column 431 and slides and extends inside the bearing shell 434 by using the extension plate 433, the lower clamping plate 75 is gradually separated from the upper clamping plate 74, and the bulge of the bearing shell 434 contacts and slides on the elastic plate 432;

step six: when the extension plate 433 gradually moves away from the bearing shell 434, the bearing plate 73 and the mounting plate 71 are guided along with the extension plate 433, and the contact between the reinforcing plate 72 and the bearing shell 434 is utilized to push the reinforcing plate 72 to slide on the bearing shell 434, so that the cooperation between the upper clamping plate 74 and the lower clamping plate 75 limits the range of the extension plate 433 extending out of the bearing shell 434.
