This is a prior art and will not be elaborated here.

[0037] Furthermore, the connecting component 201 includes a first groove 201a arranged on the inner wall of the support 108, the first groove 201a is rotatably connected to the first rotating seat 201b, the outer surface of the first rotating seat 201b is fixedly connected to the rotating seat 201c, the inner wall of the rotating seat 201c is opened with a second groove 201d, the second groove 201d is rotatably connected to the second rotating seat 201e, the first groove 201a and the second groove 201d are opened with arc grooves 201f and sliding grooves 201g, and the outer surfaces of the first rotating seat 201b and the second rotating seat 201e are fixedly connected with four first sliding blocks 201h; the buffer component 202 includes a first sliding groove 202a arranged on the upper wall of the sliding groove 201g, two sliding blocks 202b are slidably connected to the first sliding groove 202a, and the side walls of the two sliding blocks 202b are respectively fixedly connected with two composite damping springs 202c; wherein, the sliding block 202b is slidably connected to the sliding groove 201g.

[0038] Among them, Figure 5 As shown, the corresponding four first sliders 201h are symmetrically distributed in pairs, the two sliding blocks 202b are symmetrically arranged, the corresponding first slider 201h is located between the corresponding two sliding blocks 202b, two first grooves 201a are provided, and the two first grooves 201a are symmetrically arranged, the first rotating seat 201b is rotatably connected to the two first grooves 201a, two second grooves 201d are provided, and the two second grooves 201d are symmetrically arranged, the second rotating seat 201e is rotatably connected to the two second grooves 201d, and the corresponding arc groove 201f The first groove 201a is connected to the corresponding arc groove 201f, the corresponding arc groove 201d is connected to the second groove 201d, the corresponding first slider 201h is slidably connected to the corresponding arc groove 201f, the corresponding second groove 201d is connected to the corresponding sliding groove 201g, the corresponding first groove 201a is connected to the corresponding sliding groove 201g, the first sliding groove 202a is connected to the sliding groove 201g, and the corresponding first slider 201h is located in the corresponding sliding groove 201g, so that the corresponding first slider 201h can be slidably connected to the corresponding sliding groove 201g, as shown in FIG. Figure 3 As shown, the second rotating seat 201e is located between the corresponding arc groove 201f and the corresponding sliding groove 201g. Figure 4As shown, the first rotating seat 201b is located between the corresponding arc groove 201f and the corresponding sliding groove 201g, and 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 is deflected at an angle, it will squeeze the sliding block 202b, and the sliding block 202b is moved toward the composite damping spring 202c by the squeezing force, so that the composite damping spring 202c is subjected to the squeezing force of the sliding block 202b, and buffering and force elimination are achieved under the action of the composite damping spring 202c. When the first rotating seat 201b or the second rotating seat 201e is deflected, the first sliding block 201h will be driven 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 sliding block 201h will slide in the sliding groove 201g when it is deflected.

[0039] Preferably, the hook assembly 203 includes a connecting rod 203a disposed on the outer surface of the second rotating seat 201e, the lower side of the connecting rod 203a is fixedly connected to the hook body 203b, the inner side wall of the hook body 203b is fixedly connected to the guide block 203c, and the upper side of the guide block 203c is provided with a first inclined surface 203d; the lifting assembly 204 includes a lifting groove 204a disposed on the hook body 203b, the lifting groove 204a is slidably connected to the lifting seat 204b, and the lifting seat 204b is slidably connected to 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 the two first springs 204d are both fixedly connected to the side wall of the lifting seat 204b.

[0040] It should be noted that the connecting rod 203a is fixedly connected to the second rotating seat 201e, and two guide blocks 203c are provided, and the two guide blocks 203c are symmetrically arranged. The two guide blocks 203c play a guiding role, and the two first springs 204d are symmetrically arranged. When the lifting rope is hung on the hook, it slides into the U-shaped seat 204c under the action of the guide block 203c, and under the action of gravity, the lifting 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 set and is a prior art, which will not be elaborated here.

[0041] When in use, the generator to be repaired in the prior art is connected with the lifting rope, and then when the lifting rope is hung on the hook body 203b, the lifting rope will slide into the U-shaped seat 204c along the first inclined surface 203d on the guide block 203c under the action of the guide block 203c, and then under the action of the generator's own gravity, the lifting rope will drive the U-shaped seat 204c to move downward, and 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, play a role in supporting the generator, and reduce the amplitude of the generator shaking during the lifting process. When the generator shakes forward and backward or left and right, the first rotating seat 201b and the second rotating seat 201e will drive the first sliding block 201h to deflect under the action of the arc groove 201f and the sliding groove 201g. At this time, the corresponding first sliding block 201h will be squeezed to the sliding block 202b. The sliding block 202b is squeezed and displaced under the action of the first sliding groove 202a, but the deflection force is buffered and eliminated under the action of the composite damping spring 202c, thereby further reducing the amplitude of the generator shaking during the lifting process and reducing the possibility of the lifting rope being unhooked from the hook body 203b due to shaking.

[0042] In summary, through the cooperation of the connecting assembly 201, the buffer assembly 202, the hook assembly 203 and the lifting assembly 204, the swing amplitude of the lifting rope during the lifting process can be reduced, thereby reducing the possibility of the lifting rope being detached from the hook body 203b due to the shaking of the generator.

[0043] Example 2

[0044] Reference Figure 6~Figure 7 , which is the second embodiment of the present invention. Different from 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 arranged on the inner wall of the hook body 203b, and a connecting groove 301b is opened on the inner wall of the rotating groove 301a. A rotating column 301c is rotatably connected to the inner wall of the rotating groove 301a. A connecting plate 301d 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, and a third spring 301g is fixedly connected to the side wall of the sliding plate 301f; wherein the sliding plate 301f is slidably connected to the connecting groove 301b, and the third spring 301g is fixedly connected to the inner wall of the connecting groove 301b.

[0045] Specifically, two limiting components 301 are provided, 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, and 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 slide 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 being unhooked.

[0046] Furthermore, the extrusion assembly 302 includes a third groove 302a arranged on the side wall of the limiting plate 301e, the inner wall of the third groove 302a is fixedly connected to the fourth spring 302b, the side wall of the fourth spring 302b is fixedly connected to the extrusion block 302c, and the side wall of the extrusion block 302c is fixedly connected to the extrusion pad 302d; wherein the extrusion block 302c is slidably connected to the third groove 302a.

[0047] Specifically, the compression pad 302d is a soft pad, so that the suspension rope can be protected when the suspension rope is restricted.

[0048] When in use, in conjunction with Example 1, the U-shaped seat 204c will squeeze the connecting plate 301d when moving downward, so that the connecting plate 301d will 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 the lowest point, the limiting plate 301e will contact the lifting rope, thereby limiting the lifting rope and preventing the lifting rope from being unhooked. At the same time, the squeezing pad 302d drives the squeezing block 302c to further apply squeezing force to the lifting rope under the action of the fourth spring 302b, thereby improving the effect of the limiting plate 301e and the lifting rope being restricted, and effectively preventing the lifting rope from being unhooked.

[0049] In summary, through the cooperation of the limiting component 301 and the squeezing component 302, the suspension rope connected to the generator 102 can be restricted to prevent the suspension rope from being unhooked.

[0054] Specifically, the guide groove 304d is arranged in an oblique groove shape, so that when the limiting seat 303c moves in the direction 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, and play a role in pushing the sliding seat 304f to move backward; and when the limiting seat 303c moves in the direction of the lifting seat 204b under the action of the fifth spring 303b, the second slider 304b will play a role in pushing the sliding seat 304f to move forward under the action of the second slide groove 304a, the guide groove 304d and the guide block 304c.

[0055] When using, Figure 6 As shown, the fixing column 305b is in the initial position. At this time, the fixing column 305b does not contact the connecting plate 301d. In conjunction with Example 2, when the U-shaped seat 204c drives the lifting seat 204b to move downward, 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, and break away from the two limiting grooves 303d located in the middle of the side wall of the lifting seat 204b. At the same time, when the two limiting seats 303c move away from each other, the corresponding second slider 304b moves with the corresponding limiting seat 303c. At this time, the second slider 304b is moved away from the second limiting seat 303c. 304a, the guide groove 304d and the guide block 304c will slide backwards, and when the second slider 304b slides backwards, the sliding seat 304f will drive the support rod 305a and the fixed column 305b to slide backwards along with the second slider 304b, and play a role in pushing the sliding seat 304f and the support rod 305a to move backwards, so as to prevent the fixed column 305b from hindering 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 the U-shaped seat 204c moves downward and contacts the connecting plate 301d, the U-shaped seat 204c continues to descend and exerts a downward force on the connecting plate 301d, so that the connecting plate 301d drives the limiting plate 301e to deflect at an angle. When the U-shaped seat 204c is at the lowest point, the corresponding two limiting seats 303c correspond to the limiting grooves 303d on the upper side of the 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 are plugged and connected with the limiting grooves 303d to adjust the lifting seat 204. b is used to limit the position, further preventing the lifting rope from being unhooked. At the same time, the corresponding second slider 304b will move with the limiting seat 303c, and the second slider 304b will drive the sliding seat 304f to move forward under the action of the second sliding groove 304a, the guide groove 304d and the guide block 304c, thereby pushing the sliding seat 304f to move forward, so that the support rod 305a drives the fixed column 305b to move forward and insert into the corresponding fixed groove 305d along with the sliding seat 304f, so as to limit the connecting plate 301d and further prevent the lifting rope from being unhooked.

[0056] In summary, through the cooperation of the limiting assembly 303, the push-pull assembly 304 and the fixing assembly 305, the lifting seat 204b and the connecting plate 301d can be limited, thereby achieving the effect of further preventing the lifting rope from being unhooked.
