Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine generators, in particular to a wind turbine generator metal nacelle cover assembly device. Background Art

[0002] A wind turbine is an electric device that converts wind energy into mechanical work, which drives the rotor to rotate and finally outputs alternating current. A wind turbine generally consists of components such as a wind rotor, a generator, a nacelle, a tower, a speed limit safety mechanism, and an energy storage device. The wind turbine nacelle serves as the protective shell of the wind turbine, and its reliability determines the stability and service life of the wind turbine. The wind turbine nacelle covers all the components in the nacelle and isolates them from the outside. As an important component of a wind turbine, the nacelle is a protective structure of the wind turbine, which enables the wind turbine to work normally in harsh meteorological environments. The nacelle is divided into a base and a top cover. When the nacelle is assembled in the factory, the base needs to be placed on the ground first, and then the top cover is hoisted by a crane to align it with the base. At the same time, workers need to keep the base as balanced as possible so that it can be smoothly docked with the top cover.

[0003] However, the current nacelle cover has a docking hole for installing the tower under the base, so the bottom of the base is not flat, making it difficult to maintain balance. At the same time, when assembling equipment inside the nacelle cover, the nacelle cover may shake due to uneven distribution of gravity, making subsequent assembly work difficult.

[0020] See also Figure 1-3 The utility model provides a technical solution: a wind turbine metal nacelle cover assembly device, comprising a positioning seat 1 and an assembly seat 2, wherein the positioning seat 1 is provided with a scale mark 11 on the outer wall near the edge, the assembly seat 2 is provided with a rectangular groove 21 penetrating the outer wall, a plurality of rollers 22 are installed side by side in the rectangular groove 21, a slide rail 3 is provided on the positioning seat 1, a screw rod 31 is installed in the slide rail 3, a turntable 32 is installed at one end of the screw rod 31 penetrating the inner wall of the slide rail 3, a movable block 33 is symmetrically installed on the screw rod 31, and the A positioning rod 4 is installed on the top of the movable block 33, and the positioning rod 4 is provided with a threaded hole 41. A socket 42 is provided below the threaded hole 41. A threaded rod 43 is meshedly installed in the threaded hole 41, and a plug-in block 5 is installed at the socket 42. A first vertical plate 51 is provided in the plug-in block 5, and a second vertical plate 52 is installed on one side of the first vertical plate 51. A horizontal plate 53 is installed between the first vertical plate 51 and the second vertical plate 52. A plug column 6 is installed on the outer wall of the second vertical plate 52, and a bending block 7 is installed at the bottom of the second vertical plate 52.

[0021] The positioning seat 1 and the assembly seat 2 are installed in a staggered manner, and the length of the positioning seat 1 is greater than that of the assembly seat 2 .

[0022] The roller 22 is rotatably installed in the rectangular groove 21 , and the top of the roller 22 protrudes from the rectangular groove 21 .

[0023] The screw rod 31 is rotatably mounted in the slide rail 3 , and threads with opposite directions are arranged on the screw rod 31 .

[0024] The movable block 33 is slidably connected to the slide rail 3 , and a thread meshing with the screw rod 31 is formed on the inner wall of the movable block 33 at the point where the screw rod 31 passes through.

[0025] The transverse plate 53 is located at the bottom of the first vertical plate 51 and the second vertical plate 52 , and the length of the second vertical plate 52 is greater than that of the first vertical plate 51 .

[0026] The plug post 6 and the bending block 7 are located on the same side. The diameter of the plug post 6 is smaller than the insertion hole 42 , and the length of the plug post 6 is the same as that of the insertion hole 42 .

[0027] There is a distance between the bending block 7 and the plug column 6 in the vertical direction. The distance between the bending block 7 and the second vertical plate 52 is greater than the width of the positioning rod 4 . Meanwhile, the width of the first vertical plate 51 and the second vertical plate 52 is smaller than the positioning rod 4 . Figure 1 Only one location where the positioning rod 4 is installed with the plug-in block 5 is shown, and the installation methods of the other three locations are the same.

[0028] Working principle: first, use the lifting equipment to hoist the base of the cabin cover onto the roller 22 of the assembly seat 2, and then rotate the plug-in block 5 counterclockwise by ninety degrees to make the opening of the bending block 7 face the lower side. At this time, insert the plug post 6 into the socket 42, and then rotate the plug-in block 5 clockwise by ninety degrees based on the plug post 6. At this time, the bending block 7 reverses the positioning rod 4. At this point, the plug-in block 5 is installed on the positioning rod 4 and can be directly removed when not in use. It will not hinder the worker's operation. Compared with directly installing a rod-shaped object on one side of the positioning rod 4 to cooperate in achieving a limiting effect, this plug-in block 5 can be directly removed when not in use, and the installation method is simple.

[0029] Since the width of the first vertical plate 51 and the second vertical plate 52 is smaller than the positioning rod 4, when the plug-in block 5 is installed on the positioning rod 4, the positioning rod 4 and the plug-in block 5 will form a right angle. By rotating the turntable 32 to drive the screw rod 31 to rotate, the movable block 33 moves toward each other along the slide rail 3 until the edge of the cabin cover moves into the angle between the positioning rod 4 and the plug-in block 5. The cabin cover is limited at the four positioning rods 4 to maintain balance. If there is a gap between the cabin cover and the positioning rod 4, the threaded rod 43 can be rotated to press against the cabin cover.

[0030] When adjusting the position of the cabin cover at the beginning, the cabin cover can be pushed appropriately, and the roller 22 at the bottom effectively reduces the friction, effectively saving the physical strength of the staff. The scale lines 11 on both sides are used as references to allow the staff to judge the movement of the movable blocks 33 on the two positioning seats 1 to avoid the uneven movement of the movable blocks 33 and the cabin cover being tilted compared to the assembly seat 2, which causes the positioning rod 4 and the plug-in block 5 to fail to limit the cabin cover.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
