Description

Technical Field

[0001] The present invention relates to the technical field of wind turbines, and more specifically, to a new type of rotor pole assembly device for wind turbines. Background Art

[0002] A wind turbine is a power device that converts wind energy into mechanical work, with the mechanical work driving the rotor to rotate and ultimately outputting alternating current. Generally, a wind turbine consists of components such as a wind wheel, a generator (including devices), a yaw regulator (tail fin), a tower, a speed limit safety mechanism, and an energy storage device.

[0003] The working principle of a wind turbine is relatively simple. The wind wheel rotates under the action of wind, converting the kinetic energy of the wind into the mechanical energy of the wind wheel shaft, and the generator rotates driven by the wind wheel shaft to generate electricity. Broadly speaking, wind energy is also solar energy, so it can also be said that a wind turbine is a thermal energy utilization generator with the sun as the heat source and the atmosphere as the working medium.

[0004] The poles of the existing wind turbine rotor have strong suction force. There are few pole lifting devices in the existing assembly devices, and manual handling is relied on, which is extremely prone to accidents of accidental adsorption. Moreover, in the existing devices, cylinders are used to push the poles, and the repulsive force between the poles is very large. Since the cylinder thrust is small, it is easy to occur that the poles cannot be tightly pressed. The existing assembly devices have no axial positioning device. During the pushing process of the poles, the rotor will axially move with the pushing of the poles, seriously affecting production. The existing assembly equipment has no device to drive the rotor to rotate, and manual rotation of the rotor is required, seriously affecting the pole assembly efficiency.

[0005] Therefore, researching and developing an automatic pole pushing and assembling device to improve the pole assembly efficiency has become the direction of further improvement. Summary of the Invention

[0006] To solve the above technical problems, the present invention provides a new type of rotor pole assembly device for wind turbines, which includes an installation main body, a hydraulic lifting mechanism, a rotor support mechanism, and a feeding mechanism. The hydraulic lifting mechanism is slidably installed on the installation main body. A rotor support mechanism is arranged in the extending direction of the output end of the hydraulic lifting mechanism. A feeding mechanism is arranged on one side of the rotor support mechanism.

The installation main body is fixedly connected to the feeding frame. The rack group is arranged in parallel on one side of the feeding frame. The first feeding linear module is slidably installed on the rack group through a slider. The pole conveying groove is slidably installed on one side of the first feeding linear module. The second feeding linear module penetrates through the lower part of the feeding frame. A pole conveying box is arranged on the second feeding linear module. The pole conveying box is in contact connection with the pole conveying groove.

[0007] Preferably, the rotor support mechanism includes a rotor support frame, a speed reducer, a coupling, a rotating shaft, and a drum bearing seat. One end of the rotor support frame is fixedly installed with a speed reducer. The output end of the speed reducer is adaptively connected to one end of the coupling.

[0008] Preferably, the hydraulic lifting mechanism includes a lifting linear module, a mounting table, a first screw jack, a magnet assembly mechanism, and a third linear module. Lifting linear modules are oppositely arranged on both sides of the installation main body. The mounting table is slidably connected to the side of the lifting linear module through a slider. One end of the mounting table is provided with a first screw jack, and the output end of the first screw jack is adaptively connected to the magnet assembly mechanism. The bottom of the magnet assembly mechanism is slidably connected to the third linear module through a slider, and the third linear module is fixedly installed on the upper end of the mounting table.

[0009] Preferably, the magnet assembly mechanism includes a lifting frame, a fourth linear module, a second screw jack, a hydraulic cylinder, a magnet propulsion die, and an assembly workbench. The output end of the first screw jack is fixedly connected to one end of the lifting frame. The fourth linear module is fixedly installed on the lifting frame.

At this time, the servo motor drives the rack group to move, driving the magnetic pole conveying groove to rise. After reaching the specified height, the first feeding linear module pushes the magnetic pole out to the assembly workbench to be adapted to the magnetic steel pushing die.

[0024] A hydraulic lifting mechanism is slidably installed on the installation main body 1.

The magnetic pole conveying box 7 can be in contact connection with the magnetic pole conveying groove 5, which facilitates the magnetic pole to be pushed out from the magnetic pole conveying box 7 by the second feeding linear module 6 and can smoothly contact the magnetic pole conveying groove 5.

[0026] The rotor support mechanism includes a rotor support frame 8, a reducer 9, a coupling 10, a rotating shaft 11, and a drum bearing seat 12.

The transition flange 25 is fixedly connected to the coupling 10, facilitating the rotation and axial positioning of the rotor 27, and solving the problems that the rotor 27 will axially move during the pushing of the magnetic pole and the need to rotate the rotor 27 manually.

[0027] The other end of the rotating shaft 11 is adaptively connected to a mounting seat 13. The mounting seat 13 is fixed to the rotor support frame 8. Drum bearing seats 12 are provided oppositely at both ends of the rotor support frame 8. The surface of the drum bearing seat 12 is in contact with the surface of the rotating shaft 11, reducing the friction of the rotating shaft 11.

[0028] The hydraulic lifting mechanism includes a lifting linear module 14, a mounting table 15, a first screw jack 16, a magnet assembly mechanism, and a third linear module 17. Lifting linear modules 14 are provided oppositely on both sides of the installation main body 1. The rack group 3 and the lifting linear module 14 are arranged side by side.

[0031] The working principle of the present invention is as follows: The magnetic poles are manually placed on the magnetic pole conveying box 7, and the second feeding linear module 6 will push the magnetic poles into the magnetic pole conveying groove 5. At this time, the servo motor 26 drives the rack group 3 to move, driving the magnetic pole conveying groove 5 to rise. After reaching the specified height, the first feeding linear module 4 pushes the magnetic poles onto the assembly workbench 23 to be adapted to the magnet propulsion die 22. Then, the hydraulic cylinder 21 is pushed out to push the magnetic poles to the rotor 27 to complete the assembly.

[0032] The overall structure of the present invention is simple. Through the pneumatic pushing of the first screw lift 16 and the second screw lift 20, the pressing between the magnetic poles is greatly promoted. The axial positioning of the rotor 27 is realized through the cooperation of the rotor support mechanism, and the assembly is smooth. The transmission and installation of the magnetic poles are all carried out through mechanical braking, with high working safety, labor saving, and greatly improved efficiency of the rotor 27 assembly.
