[0003] A search revealed a Chinese patent with publication number CN221722956U, which discloses a rotating assembly bracket for a wind turbine generator. The bracket uses two limiting rods to limit the push plate and improve its stability. However, the angle of the side plate after rotation is fixed by a motor, which can easily overload the motor and cause it to be damaged, thus affecting the normal use of the bracket. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an auxiliary tilting bracket for wind turbine assembly to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an auxiliary tilting bracket for assembling a wind turbine generator, including a base, with slides slidably connected to both sides of the base, and the slides being moved up and down by an adjusting component. A rotating shaft is rotatably connected to one side of the slide, and a U-shaped frame is keyed between the two rotating shafts. A turntable is provided on the top of the U-shaped frame, and a positioning component for fixing the generator housing is provided on the top of the turntable. A power component for driving the rotating shaft to rotate is provided on one side of the slide, and a third gear is keyed to the outer circumference of the rotating shaft. A slider is slidably connected between the inner walls of the two sides of the slide, and an elastic rubber block is adhered to one side of the slider, and the elastic rubber block is in contact with the third gear. A pushing component is provided on the top of the slide to push the slider towards the third gear and maintain its position.

[0006] As a further embodiment of this utility model, the pushing assembly includes an electric push rod fixed to the top outer wall of the slide, the movable end of the electric push rod is fixed to a bracket by bolts, and the slider is located inside the bracket. One end of each side inner wall of the bracket is an inclined surface, and the inclined surface is at a distance from the top inner wall of the bracket.

[0007] As a further embodiment of this utility model, the power assembly includes a servo motor fixed to one side of the slide, the output shaft of the servo motor passing through the slide and connected to a first gear by a key, and one end of the rotating shaft being connected to a second gear by a key, and the first gear meshing with the second gear.

[0008] As a further embodiment of this utility model, the adjustment component includes a hydraulic cylinder fixed to the inner wall of the bottom of the base, and the movable end of the hydraulic cylinder is fixed to the slide.

[0009] As a further embodiment of this utility model, mounting grooves are provided on the top of the opposite sides of the two sliders, and auxiliary rollers are rolled in the mounting grooves. The distance between the inclined surface and the inner wall of the top of the bracket is not less than the diameter of the auxiliary rollers.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-4 This utility model provides an auxiliary tilting bracket for assembling a wind turbine generator, including a base 1. Slides 2 are slidably connected to both sides of the base 1, and the slides 2 are moved up and down by an adjusting component. A rotating shaft 8 is rotatably connected to one side of the slides 2. A U-shaped frame 4 is keyed between the two rotating shafts 8. A turntable 5 is provided on the top of the U-shaped frame 4. A positioning component for fixing the generator housing is provided on the top of the turntable 5. A power component for driving the rotating shaft 8 to rotate is provided on one side of the slides 2. A third gear 18 is keyed to the outer circumference of the rotating shaft 8. A slider 12 is slidably connected between the inner walls of the two sides of the slides 2. An elastic rubber block 17 is adhered to one side of the slider 12 and is in contact with the third gear 18. A pushing component is provided on the top of the slides 2 to push the slider 12 toward the third gear 18 and maintain its position.

[0024] In use, the generator housing is first placed on the turntable 5 and fixed using the positioning component. The height of the slide 2 and the generator housing is adjusted by the adjustment component. The U-shaped frame 4 is rotated by the power component to adjust the longitudinal angle of the generator housing. The lateral angle of the generator housing can be adjusted by the turntable 5. After the U-shaped frame 4 is rotated by the power component, the slider 12 is pushed towards the third gear 18 by the pushing component. This causes the elastic rubber block 17 to squeeze the third gear 18, so that the elastic rubber block 17 deforms and is completely inserted into the tooth groove of the third gear 18, thereby completing the auxiliary fixation of the rotating shaft 8 and the auxiliary fixation of the rotation angle of the U-shaped frame 4, improving the fixation effect of the bracket.

[0025] In this utility model, the pushing component includes an electric push rod 14 fixed to the top outer wall of the slide 2. The movable end of the electric push rod 14 is fixed to the insert 11 by bolts, and the slider 12 is located inside the insert 11. One end of the inner walls on both sides of the insert 11 is a slope 13, and the slope 13 is at a distance from the top inner wall of the insert 11.

[0026] When the electric push rod 14 is activated, it extends and moves the insert 11 downward, causing the inclined plane 13 to press the slider 12 toward the third gear 18 until the other end of the slider 12 is above the inclined plane 13, thus providing auxiliary limit for the slider 12. At this time, the electric push rod 14 is not under force, so the slider 12 continues to maintain this position, improving the stability of the bracket fixation.

[0027] Among them, the top of the two sliders 12 on opposite sides is provided with mounting grooves 16, and auxiliary rollers 15 are rolled in the mounting grooves 16. The distance between the inclined surface 13 and the inner wall of the top of the bracket 11 is not less than the diameter of the auxiliary rollers 15.

[0028] The auxiliary roller 15 reduces the friction between the slider 12 and the inclined plane 13, allowing the insert 11 to better push the slider 12 to move. Furthermore, the diameter of the auxiliary roller 15 is smaller than the distance between the inclined plane 13 and the top inner wall of the insert 11, ensuring that the auxiliary roller 15 is completely within the distance between the inclined plane 13 and the top inner wall of the insert 11.

[0029] Furthermore, the power assembly includes a servo motor 10 fixed to one side of the slide 2. The output shaft of the servo motor 10 passes through the slide 2 and is keyed to a first gear 7. One end of the rotating shaft 8 is keyed to a second gear 9, and the first gear 7 and the second gear 9 mesh.

[0030] Start the servo motor 10, which drives the first gear 7 to rotate, thereby driving the second gear 9 to rotate, which in turn drives the rotating shaft 8 to rotate, thus changing the angle of the U-shaped frame 4.

[0031] In this configuration, the number of teeth on the first gear 7 is much smaller than the number of teeth on the second gear 9, resulting in a larger tooth ratio. This causes the first gear 7 to drive the second gear 9 to rotate as a speed reduction transmission, increasing the torque that the second gear 9 uses to drive the rotating shaft 8. This makes the rotation of the U-shaped frame 4 easier and improves the protection effect of the bracket on the servo motor 10.

[0032] Furthermore, the adjustment component includes a hydraulic cylinder 6 fixed to the inner wall of the bottom of the base 1, and the movable end of the hydraulic cylinder 6 is fixed to the slide 2. When the hydraulic cylinder 6 is activated, the extension of the hydraulic cylinder 6 will drive the slide 2 to move upward, and the retraction of the hydraulic cylinder 6 will drive the slide 2 to move downward, thereby achieving the purpose of adjusting the height of the U-shaped frame 4.

[0033] Among them, multiple guide rods 3 are fixed between the bottom and the top inner wall of the base 1 by bolts, and the guide rods 3 pass through the slide 2 and slide in connection with the slide 2 to guide the movement of the slide 2 and make the movement of the slide 2 more stable.

[0034] Furthermore, a support roller 20 is rotatably connected to the bottom inner wall of the base 1, and two arc-shaped plates 19 are welded to the bottom of the U-shaped frame 4. The arc-shaped plates 19 are in contact with the support roller 20, and the arc center of the arc-shaped plate 19 is coaxial with the rotation point of the U-shaped frame 4. The support roller 20 provides auxiliary support for the arc-shaped plate 19, reduces the support of the rotating shaft 8 on the U-shaped frame 4, and improves the service life of the rotating shaft 8.

[0035] In addition, the positioning component adopts the same positioning component as that in the Chinese patent with announcement number CN221722956U, including screw, handle, push plate, lifting plate and limit rod. Its structure and principle are the same as the positioning component in the patent document with announcement number CN221722956U, and will not be elaborated on here.

[0036] It should be noted that the transfer platform 5, hydraulic cylinder 6, servo motor 10 and electric push rod 14 of this utility model are all electrical devices or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods, and will not be described in detail here.

[0037] The working principle of this utility model is as follows: In use, the generator housing is first placed on the turntable 5 and fixed using a positioning assembly. The hydraulic cylinder 6 is activated, extending to move the slide 2 upwards, adjusting the height of the U-shaped frame 4 relative to the generator housing. The servo motor 10 is then activated, driving the first gear 7 to rotate, which in turn drives the second gear 9 to rotate, and consequently the rotating shaft 8, thus changing the angle between the U-shaped frame 4 and the generator housing. After the U-shaped frame 4 rotates, the electric push rod 14 is activated, extending to move the insert bracket 11. The slider moves downward, causing the inclined plane 13 to press the slider 12 towards the third gear 18. This causes the elastic rubber block 17 to press the third gear 18, deforming the elastic rubber block 17 and completely engaging it in the tooth groove of the third gear 18, until the other end of the slider 12 is above the inclined plane 13. At this point, the side above the inclined plane 13 will provide auxiliary limiting for the slider 12. The electric push rod 14 is not under force, thus keeping the slider 12 in this position. This completes the auxiliary fixation of the rotating shaft 8, and further assists in fixing the rotation angle of the U-shaped frame 4, improving the fixing effect of the bracket.

[0038] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship.
