[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0033] Example 1

[0034] Referring to Figures 1-11, this is the first embodiment of the present invention. This embodiment provides a wind turbine hoisting device that can reduce the possibility of the hoisting rope connected to the generator 102 detaching from the hook body 203b due to swaying. The device includes a main component 100, which comprises a fixed base 101, a motor 102 disposed on the side wall of the fixed base 101, a winding roller 103 disposed on the motor 102, a wire rope 104 disposed on the winding roller 103, a lifting plate 105 disposed at the end of the wire rope 104, a lifting groove 106 disposed on the inner side wall of the fixed base 101, a sliding seat 107 disposed on the side wall of the lifting plate 105, and a device disposed on the lower side of the lifting plate 105. Two supports 108; a connecting component 200, the connecting component 200 including a connecting assembly 201 disposed in the support 108, a buffer assembly 202 disposed in the connecting assembly 201, a hook assembly 203 disposed on the connecting assembly 201, and a lifting assembly 204 disposed on the hook assembly 203; a limiting component 300, the limiting component 300 including a limiting assembly 301 disposed in the hook assembly 203, a pressing assembly 302 disposed on the side wall of the limiting assembly 301, a limiting assembly 303 disposed in the hook assembly 203, a push-pull assembly 304 disposed on the side wall of the limiting assembly 303, and a fixing assembly 305 disposed on the side wall of the push-pull assembly 304.

[0035] Specifically, the motor 102 is fixedly installed on the side wall of the fixed base 101. The output end of the motor 102 is fixedly connected to the winding roller 103. The wire rope 104 is wound around the winding roller 103. The lifting plate 105 is fixedly connected to the end of the wire rope 104. There are two slides 107 and two lifting grooves 106, and the two slides 107 and two lifting grooves 106 are symmetrically arranged. The slides 107 and the lifting grooves 106 are slidably connected, and the two slides 107 are symmetrically arranged. The two supports 108 are symmetrically arranged. The motor 102 is a motor that can support forward and reverse rotation, so that when the motor 102 is started, the winding roller 103 can rotate forward or reverse to realize the winding and unwinding of the wire rope 104. This is the prior art and will not be described in detail here.

[0036] Furthermore, the connecting component 201 includes a first groove 201a disposed on the inner sidewall of the support 108, a first rotating seat 201b rotatably connected in the first groove 201a, a rotating seat 201c fixedly connected to the outer surface of the first rotating seat 201b, a second groove 201d opened on the inner sidewall of the rotating seat 201c, a second rotating seat 201e rotatably connected in the second groove 201d, an arc-shaped groove 201f and a sliding groove 201g opened in both the first groove 201a and the second groove 201d, and four first sliders 201h fixedly connected to the outer surfaces of both the first rotating seat 201b and the second rotating seat 201e; the buffer component 202 includes a first sliding groove 202a disposed on the upper wall of the sliding groove 201g, two sliding blocks 202b slidably connected in the first sliding groove 202a, and two composite damping springs 202c fixedly connected to the sidewalls of the two sliding blocks 202b respectively; wherein, the sliding blocks 202b are slidably connected to the sliding groove 201g.

[0037] As shown in Figure 5, the four first sliders 201h are symmetrically distributed in pairs, and the two sliding blocks 202b are symmetrically arranged. The corresponding first slider 201h is located between the corresponding two sliding blocks 202b. There are two first grooves 201a, which are symmetrically arranged. The first rotating seat 201b is rotatably connected to the two first grooves 201a. There are two second grooves 201d, which are symmetrically arranged. The second rotating seat 201e is rotatably connected to the two second grooves 201d. The corresponding arc-shaped groove 201f communicates with the first groove 201a, the corresponding arc-shaped groove 201f communicates with the second groove 201d, the corresponding first slider 201h is slidably connected to the corresponding arc-shaped groove 201f, the corresponding second groove 201d communicates with the corresponding sliding groove 201g, the corresponding first groove 201a communicates with the corresponding sliding groove 201g, the first sliding groove 202a communicates with the sliding groove 201g, and the corresponding first slider 201h is located within the corresponding sliding groove 201g, so that the corresponding first slider 201h can... The corresponding sliding groove 201g is slidably connected, as shown in Figure 3. The second rotating seat 201e is located between the corresponding arc-shaped groove 201f and the corresponding sliding groove 201g, as shown in Figure 4. The first rotating seat 201b is located between the corresponding arc-shaped groove 201f and the corresponding sliding groove 201g. The other side of the corresponding composite damping spring 202c is fixedly connected to the inner wall of the sliding groove 201g. Through the composite damping spring 202c, when the first rotating seat 201b or the second rotating seat 201e undergoes angular deflection, it will press against the sliding block 202b. The material moves towards the composite damping spring 202c under the pressure of the compression, causing the composite damping spring 202c to be subjected to the compression force of the sliding block 202b. Under the action of the composite damping spring 202c, buffering and force dissipation are achieved. When the first rotating seat 201b or the second rotating seat 201e deflects, it will drive the first slider 201h to deflect. Since the corresponding sliding groove 201g is connected to the first groove 201a and the corresponding sliding groove 201g is connected to the second groove 201d, the corresponding first slider 201h will slide in the sliding groove 201g when it deflects.

[0038] Preferably, the hook assembly 203 includes a connecting rod 203a disposed on the outer surface of the second rotating seat 201e, a hook body 203b fixedly connected to the lower side of the connecting rod 203a, a guide block 203c fixedly connected to the inner wall of the hook body 203b, and a first inclined surface 203d provided on the upper side of the guide block 203c; the lifting assembly 204 includes a lifting channel 204a disposed on the hook body 203b, a lifting seat 204b slidably connected in the lifting channel 204a, and the lifting seat 204b... A U-shaped seat 204c is fixedly connected to the upper side of 04b, two first springs 204d are fixedly connected to the lower side of the hook body 203b, a second spring 204e is fixedly connected to the side wall of the lifting seat 204b, a pressing seat 204f is fixedly connected to the lower side of the second spring 204e, and an anti-slip pad 204g is fixedly connected to the lower side of the pressing seat 204f; wherein, the pressing seat 204f is slidably connected to the lifting seat 204b, and both first springs 204d are fixedly connected to the side wall of the lifting seat 204b.

[0039] It should be noted that the connecting rod 203a is fixedly connected to the second rotating seat 201e. There are two guide blocks 203c, which are symmetrically arranged and serve as guides. The two first springs 204d are symmetrically arranged. When the hoisting rope is hung on the hook, it slides into the U-shaped seat 204c under the action of the guide blocks 203c. Under the action of gravity, the hoisting rope will drive the U-shaped seat 204c to move downward, so that the lifting seat 204b drives the pressing seat 204f to move downward, so that the anti-slip pad 204g can contact the hoisted generator. The generator is an important component of the wind turbine and is existing technology, so it will not be described in detail here.

[0040] In existing technology, when the generator to be repaired is connected to the hoisting rope and the rope is hung on the hook body 203b, the rope slides down the first inclined surface 203d on the guide block 203c into the U-shaped seat 204c under the action of the guide block 203c. Then, under the action of the generator's own weight, the rope will drive the U-shaped seat 204c to move downward. At this time, the lifting seat 204b will drive the pressing seat 204f to move downward, so that the anti-slip pad 204g can contact the generator, which plays a role in supporting the generator and reducing the amplitude of the generator's swaying during hoisting. At the same time, when the generator... When the generator sways back and forth or left and right, the first rotating seat 201b and the second rotating seat 201e will cause the first slider 201h to deflect under the action of the arc groove 201f and the sliding groove 201g. At this time, the corresponding first slider 201h will press against the sliding block 202b. The sliding block 202b will be displaced under the action of the first sliding groove 202a due to the pressure. However, under the action of the composite damping spring 202c, the deflection force is buffered and dissipated, further reducing the amplitude of the generator's sway during hoisting and reducing the possibility of the hoisting rope detaching from the hook body 203b due to swaying.

[0041] In summary, by cooperating with the connecting component 201, the buffer component 202, the hook component 203, and the lifting component 204, the amplitude of the swaying of the hoisting rope during the hoisting process can be reduced, thereby reducing the possibility of the hoisting rope detaching from the hook body 203b due to the generator swaying.

[0042] Example 2

[0043] Referring to Figures 6 and 7, this is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a wind turbine hoisting device, which includes a limiting component 301. The limiting component 301 includes a rotating groove 301a disposed on the inner sidewall of the hook body 203b. A connecting groove 301b is opened on the inner sidewall of the rotating groove 301a. A rotating column 301c is rotatably connected to the inner sidewall of the rotating groove 301a. A connecting plate 301d is fixedly connected to the outer surface of the rotating column 301c. A limiting plate 301e is fixedly connected to the outer surface of the rotating column 301c. A sliding plate 301f is fixedly connected to the outer surface of the rotating column 301c. A third spring 301g is fixedly connected to the sidewall of the sliding plate 301f. The sliding plate 301f is slidably connected to the connecting groove 301b, and the third spring 301g is fixedly connected to the inner sidewall of the connecting groove 301b.

[0044] Specifically, there are two limiting components 301, and the two limiting components 301 are symmetrically arranged. The connecting groove 301b is connected to the rotating groove 301a. The limiting plates 301e are slidably connected to the rotating groove 301a. The connecting plate 301d is slidably connected to the hook body 203b. When the U-shaped seat 204c moves downward, it will squeeze the connecting plate 301d, so that the connecting plate 301d will drive the limiting plate 301e and the sliding plate 301f to rotate around the rotating column 301c under the action of the rotating column 301c. When the U-shaped seat 204c is at the lowest point, the limiting plate 301e will contact the lifting rope, thereby limiting the lifting rope and preventing the lifting rope from getting off the hook.

[0045] Furthermore, the extrusion assembly 302 includes a third groove 302a disposed on the side wall of the limiting plate 301e, a fourth spring 302b fixedly connected to the inner side wall of the third groove 302a, an extrusion block 302c fixedly connected to the side wall of the fourth spring 302b, and an extrusion pad 302d fixedly connected to the side wall of the extrusion block 302c; wherein, the extrusion block 302c is slidably connected to the third groove 302a.

[0046] Specifically, the compression pad 302d is a soft pad that protects the suspension rope when it is restricted.

[0047] In use, in conjunction with Embodiment 1, when the U-shaped seat 204c moves downward, it will press against the connecting plate 301d. This causes the connecting plate 301d to drive the limiting plate 301e and the sliding plate 301f to deflect around the rotating column 301c under the action of the rotating column 301c. When the U-shaped seat 204c is at its lowest point, the limiting plate 301e will contact the lifting rope, thereby limiting the lifting rope and preventing it from coming off the hook. At the same time, the pressing pad 302d drives the pressing block 302c to further apply pressure to the lifting rope under the action of the fourth spring 302b, improving the limiting effect between the limiting plate 301e and the lifting rope and effectively preventing the lifting rope from coming off the hook.

[0048] In summary, by combining the limiting component 301 and the squeezing component 302, the hoisting rope connected to the generator 102 can be restricted, thereby preventing the hoisting rope from coming off the hook.

[0049] Example 3

[0050] Referring to Figures 6-12, this is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a wind turbine hoisting device, which includes a limiting component 303. The limiting component 303 includes a fourth groove 303a disposed in the hook body 203b. Two fifth springs 303b are fixedly connected to the inner side wall of the fourth groove 303a. The other side of the two fifth springs 303b is fixedly connected to a limiting seat 303c. A limiting groove 303d is opened on the side wall of the lifting seat 204b. A second inclined surface 303e is provided on the inner side wall of the limiting groove 303d. A third inclined surface 303f is provided on the side wall of the limiting seat 303c. The limiting seat 303c is slidably connected to the fourth groove 303a, and the limiting seat 303c is inserted into the limiting groove 303d.

[0051] Specifically, there are two limiting components 303, which are symmetrically arranged. There are also two fifth springs 303b, which are symmetrically arranged, as shown in Figure 10. The upper part and the middle part of the side wall of the lifting seat 204b are each provided with two symmetrically distributed limiting grooves 303d. The second inclined surface 303e and the third inclined surface 303f are adapted to each other. The limiting seat 303c and the limiting grooves 303d play a role in limiting and fixing the lifting seat 204b.

[0052] Furthermore, the push-pull assembly 304 includes a second slide groove 304a disposed on the side wall of the limiting seat 303c, a second slider 304b slidably connected within the second slide groove 304a, a guide block 304c fixedly connected to the lower side of the second slider 304b, a guide groove 304d formed on the lower wall of the fourth groove 303a, a first through groove 304e formed on the inner side wall of the fourth groove 303a, a sliding seat 304f slidably connected to the inner side wall of the first through groove 304e, and a third slide groove 304g formed on the side wall of the sliding seat 304f; wherein, the guide... Block 304c is slidably connected to guide groove 304d, and second slider 304b is slidably connected to third slide groove 304g; the fixing component 305 includes a support rod 305a disposed on the rear side of sliding seat 304f, a fixing column 305b fixedly connected to the side wall of support rod 305a, a second through groove 305c opened on the rear side of hook body 203b, and a fixing groove 305d opened on the side wall of connecting plate 301d; wherein, fixing column 305b is slidably connected to second through groove 305c, and fixing column 305b is inserted into fixing groove 305d.

[0053] Specifically, the guide groove 304d is slanted, so that when the limiting seat 303c moves away from the lifting seat 204b, the second slider 304b will slide backward under the action of the second slide groove 304a, the guide groove 304d and the guide block 304c, thus pushing the sliding seat 304f to move backward. When the limiting seat 303c moves towards the lifting seat 204b under the action of the fifth spring 303b, the second slider 304b will push the sliding seat 304f forward under the action of the second slide groove 304a, the guide groove 304d and the guide block 304c.

[0054] In use, as shown in Figure 6, the fixed post 305b is in its initial position, at which time the fixed post 305b is not in contact with the connecting plate 301d. In accordance with Embodiment 2, when the U-shaped seat 204c drives the lifting seat 204b downwards, the corresponding two limiting seats 303c will move away from each other under the action of the second inclined surface 303e and the third inclined surface 303f, disengaging from the two limiting grooves 303d located in the middle of the side wall of the lifting seat 204b. Simultaneously, as the two limiting seats 303c move away from each other, the corresponding second slider 304b moves along with the corresponding limiting seat 303c. The second slider 304b will slide backward under the action of the second slide groove 304a, guide groove 304d, and guide block 304c. When the second slider 304b slides backward, the sliding seat 304f will drive the support rod 305a and the fixed column 305b to slide backward along with the second slider 304b, which plays a role in pushing the sliding seat 304f and the support rod 305a to move backward, preventing the fixed column 305b from obstructing the deflection of the connecting plate 301d, so that the connecting plate 301d can drive the limiting plate 301e and the sliding plate 301f to deflect smoothly. When U When the U-shaped seat 204c moves downward and contacts the connecting plate 301d, the continued descent of the U-shaped seat 204c will exert a downward force on the connecting plate 301d, causing the connecting plate 301d to drive the limiting plate 301e to deflect at an angle. When the U-shaped seat 204c is at its lowest point, the two corresponding limiting seats 303c correspond to the limiting grooves 303d on the upper side wall of the lifting seat 204b. At this time, the two limiting seats 303c will move closer to each other under the action of the fifth spring 303b, so that the limiting seats 303c and the limiting grooves 303d are inserted and connected to the lifting seat 204b. 04b is used for limiting to further prevent the lifting rope from coming off the hook. At the same time, the corresponding second slider 304b will move with the limiting seat 303c. Under the action of the second sliding groove 304a, guide groove 304d and guide block 304c, the second slider 304b will drive the sliding seat 304f to move forward, which will push the sliding seat 304f to move forward, so that the support rod 305a moves forward with the sliding seat 304f and drives the fixed column 305b to insert into the corresponding fixed groove 305d, thereby limiting the connecting plate 301d and further preventing the lifting rope from coming off the hook.

[0055] In summary, the combination of the limiting component 303, the push-pull component 304, and the fixing component 305 can limit the lifting seat 204b and the connecting plate 301d, thereby further preventing the lifting rope from coming off the hook.
