[0019] Compared with the prior art, the present application has the following advantages:

[0020] 1. When hoisting tower, generator set and blades with different sizes, the four main hoisting ropes are adjusted in the direction of the guide unit to make the main hoisting ropes exert pulling force on the components in the vertical direction, which can effectively avoid the deformation of the components during hoisting, especially for long and flexible blades, which can prevent the traditional hoisting method from easily causing the deformation of the two ends to the middle part, thereby ensuring the integrity and stability of the components during hoisting;

[0021] 2. In the device design for hoisting the components, two rotatable rolling rods are arranged in each mounting port, and the main hoisting rope passes through the position between the two rolling rods. When the position of the sliding plate is adjusted, the mounting port moves relative to the main hoisting rope, and the rolling rod will rotate under the friction force of the main hoisting rope. This design avoids the direct contact between the main hoisting rope and the inner surface of the mounting port, effectively prevents the mutual abrasion between the main hoisting rope and the sliding plate, and plays a good protective role on the main hoisting rope;

[0022] 3. Before adjusting the positions of the two sliding plates, the worker only needs to pull the connecting rod upwards to drive the horizontal plate and the two positioning rods to move upwards and separate from the positioning ports, so as to release the restriction on the sliding plates and make them slide freely. After the adjustment is completed, the positioning rods automatically face the positioning ports, the connecting rod is loosened, the horizontal plate is reset under the action of the connecting spring, the positioning rods are reinserted into the positioning ports, and the fixation of the sliding plates is quickly realized. This design not only guarantees the flexibility of the position adjustment of the sliding plates, but also ensures the stability of the sliding plates after adjustment, effectively avoids the accidental movement of the sliding plates due to external forces and other factors during use, improves the reliability and safety of the whole adjusting device, and provides a stable basis for subsequent hoisting operations and other operations;

[0023] 4. When adjusting the sliding plate, the worker pulls the connecting rod upwards to make the limiting block pass through the limiting port, then rotates the connecting rod, and makes the limiting block rest on the limiting ring, so as to fix the position of the connecting rod and the horizontal plate. It is not necessary to always pull the connecting rod, which greatly reduces the operation burden of the worker and improves the operation convenience. After the position of the sliding plate is adjusted, the connecting rod and the limiting block can be reset by reverse operation. The overall design is simple and easy to control, which effectively improves the efficiency and stability of the sliding plate adjustment;

[0024] 5. The auxiliary installation equipment for the wind turbine set provided by the present application has the anti-shaking function, which has obvious advantages in the tower hoisting operation. The guide unit is assembled at the lowermost end of the tower, the guide frame provides limiting for the hoisted tower, which effectively prevents the tower from shaking. At the same time, the rollers on the guide frame can reduce the friction with the tower, which is convenient for movement. In addition, the guide frame can also rotate freely, which further improves the flexibility and adaptability of the operation, and provides safe and efficient protection for the tower hoisting operation.

[0044] Referring to Figures 4-7 As shown, the first adjusting assembly comprises a rotating shaft 31, two first screw rods 32, two first fixed blocks 33, two guide rods 34 and four second fixed blocks 35, the rotating shaft 31 is rotatably installed on the fixed plate 21, a hand wheel is fixedly sleeved on the rotating shaft 31, the hand wheel is opposite to the through hole, the two first screw rods 32 are fixed at the two ends of the rotating shaft 31 respectively, the two first fixed blocks 33 are fixed on the two adjusting plates 22 respectively, the two first fixed blocks 33 are threadedly sleeved on the two first screw rods 32 respectively, the two guide rods 34 are fixed at the two ends of the fixed plate 21 respectively, and the four second fixed blocks 35 are fixed at the two ends of the two adjusting plates 22 respectively, wherein two of the second fixed blocks 35 are slidably sleeved on one of the guide rods 34, and the other two second fixed blocks 35 are slidably sleeved on the other guide rod 34;

[0045] Referring to Figures 4-7 As shown, the second adjusting assembly comprises two sliding plates 41, the adjusting plate 22 is provided with a through hole, the two sliding plates 41 are slidably arranged at the two ends of the through hole respectively, the ends of the two sliding plates 41 away from each other both extend to the outside of the through hole, the ends of the two sliding plates 41 away from each other are both provided with a mounting hole 43, two rotatable rolling rods 44 are arranged in each mounting hole 43, and the four main slings pass through the four mounting holes 43 respectively, the second adjusting assembly further comprises a second screw rod 45 and two third fixed blocks 46, the second screw rod 45 is rotatably installed on the bottom surface of the adjusting plate 22, the two third fixed blocks 46 are fixed on the two sliding plates 41 respectively, and the two third fixed blocks 46 are threadedly sleeved on the second screw rod 45, the bottom surface of the adjusting plate 22 is provided with a strip-shaped opening 42, and the strip-shaped opening 42 is in communication with the through hole, and the two third fixed blocks 46 are slidably arranged in the strip-shaped opening 42;

[0046] When hoisting the tower section, the generator set and the blades with different sizes, the tension direction of the four main hoisting ropes is adjusted by the guide unit, so that the main hoisting ropes can exert tension on the component in the vertical direction, which can effectively avoid the deformation of the component during hoisting, especially for the long and flexible blades, the traditional hoisting method is easy to cause the deformation of the two ends to the middle, and the limiting effect of the guide unit can well prevent such problems, and guarantee the integrity and stability of the component during hoisting. Specifically, the workers thread the four main hoisting ropes through the four mounting holes 43, and provide guidance for the four main hoisting ropes by adjusting the positions of the four sliding plates 41. When adjusting the distance between the two adjusting plates 22, the workers rotate the hand wheel on the shaft 31, so that the shaft 31 rotates, and the two first screws 32 on the shaft 31 rotate. Under the limiting action of the two guide rods 34 and the four second fixed blocks 35, the two first screws 32 rotate to drive the two first fixed blocks 33 to move synchronously, so that the two adjusting plates 22 move closer to each other or move away from each other. For the adjusting plate 22, the workers can also drive the two third fixed blocks 46 to move closer to each other or move away from each other by rotating the second screw 45, so that the two sliding plates 41 on the adjusting plate 22 move closer to each other or move away from each other. Based on the above process, the workers can adjust the positions of the four sliding plates 41 by rotating the first screw 32 and the second screw 45, so as to adjust the positions of the four mounting holes 43. The workers adjust the positions of the four mounting holes 43 until the four main hoisting ropes can exert tension on the component in the vertical direction.

[0047] It is worth noting that two rotatable rolling rods 44 are arranged in each mounting hole 43, and the main hoisting rope passes through the position between the two rolling rods 44. When adjusting the position of the sliding plate 41, the mounting hole 43 and the main hoisting rope will move relatively, and in this process, the rolling rod 44 will rotate under the action of the friction force between the main hoisting rope and the rolling rod 44. The design of the rolling rod 44 can avoid the direct contact between the main hoisting rope and the inner surface of the mounting hole 43, and avoid the mutual abrasion between the main hoisting rope and the sliding plate 41, which protects the main hoisting rope.

[0048] Referring to Figure 9As shown, the positioning assembly comprises two sockets 51, four positioning ports 52, a cross plate 53, two positioning rods 54, a mounting frame 55 and a limiting structure, the two sockets 51 are both arranged on the adjusting plate 22, the two sockets 51 are both in communication with the through hole, the four positioning ports 52 are in two groups respectively and are both arranged on the two sliding plates 41, the two positioning rods 54 are both fixed at two ends of the cross plate 53 and are both inserted into the two sockets 51, the mounting frame 55 is fixed on the adjusting plate 22, the cross plate 53 and the mounting frame 55 are connected through a connecting spring 57, the limiting structure is arranged on the mounting frame 55, the limiting structure comprises a connecting rod 56, a limiting ring 58, a limiting port 510 and a limiting block 511, the connecting rod 56 is rotatably arranged at the middle position of the top surface of the cross plate 53, the connecting rod 56 penetrates through the mounting frame 55 and is slidably connected with the mounting frame 55, the limiting ring 58 is arranged above the mounting frame 55 and is connected with the mounting frame 55 through two vertical rods 59, the limiting port 510 is arranged on the limiting ring 58, and the limiting block 511 is fixed on the outer surface of the connecting rod 56, the limiting ring 58, the limiting port 510 and the connecting rod 56 are coaxially arranged;

[0049] Each adjusting plate 22 is provided with a positioning assembly, the positioning assembly can ensure the position stability of the two sliding plates 41, before adjusting the positions of the two sliding plates 41, the worker first pulls the connecting rod 56 upwards, so that the connecting rod 56 drives the cross plate 53 to move upwards, when the cross plate 53 moves upwards, the two positioning rods 54 on the cross plate 53 move upwards, until the two positioning rods 54 are completely separated from the corresponding positioning ports 52, the two sliding plates 41 can be freely slid without the limiting action of the two positioning rods 54, when the positions of the two sliding plates 41 are adjusted, the two positioning rods 54 are opposite to the positioning ports 52 on the two sliding plates 41 again, at this time, the worker releases the connecting rod 56, so that the cross plate 53 is reset under the action of the connecting spring 57, when the cross plate 53 is reset, the two positioning rods 54 are inserted into the corresponding positioning ports 52 again, so that the two sliding plates 41 are fixed, and the stability of the sliding plates 41 is ensured;

[0050] In addition, when the staff pulls the connecting rod 56 upwards, the limiting block 511 on the connecting rod 56 moves, in the process, the limiting block 511 passes through the limiting opening 510, when the limiting block 511 moves above the limiting ring 58, the staff rotates the connecting rod 56, so that the connecting rod 56 rotates with the limiting ring 58, until the limiting block 511 and the limiting opening 510 are staggered with each other, in this case, the limiting block 511 cannot pass through the limiting opening 510 again, but will be placed on the limiting ring 58, when the position of the limiting block 511 is fixed, the position of the connecting rod 56 and the horizontal plate 53 is fixed, this design does not require the staff to always pull the connecting rod 56 when adjusting the position of the two sliding plates 41, after adjusting the position of the two sliding plates 41, the staff reverses the above process to reset the connecting rod 56 and the limiting block 511;

[0051] Referring to Figure 2 、 Figure 12 and Figure 13 , the second traction device 61 is installed on the beam arm of the crane 101, the traction cable 62 is arranged on the second traction device 61, the traction end of the traction cable 62 is provided with an anti-shaking unit, the anti-shaking unit is composed of two guide assemblies; the guide assembly includes a guide frame 63, a plurality of rollers 64, a vertical plate 65, a first air cylinder 66, a side plate 68 and a second air cylinder, the plurality of rollers 64 are respectively installed at the upper and lower ends of the guide frame 63, each guide frame 63 is provided with an arc-shaped part, when the two guide frames 63 are spliced together, the two arc-shaped parts jointly form a circular area, each roller 64 is located in the circular area, the vertical plate 65 is fixed on the guide frame 63, the vertical plate 65 is provided with a hole, the first air cylinder 66 is installed in the hole, the first air cylinder 66 is fixed with a first pressing block 67 at the extension end, the side plate 68 is fixed on the guide frame 63, the side plate 68 is provided with the second air cylinder 69 at the end away from the guide frame 63, the second air cylinder 69 is fixed with a second pressing block 610 at the extension end, the first pressing block 67 and the second pressing block 610 are made of rubber material;

[0052] The auxiliary installation equipment for the wind turbine generator set has the anti-shaking function. When the tower drum is hoisted, the staff first fixes the lowermost tower drum, and then assembles the guide unit on the lowermost tower drum. When the remaining tower drums are hoisted, the staff can provide the limit for the hoisted tower drum by using the guide unit, so as to prevent the tower drum from shaking in the hoisting process. Specifically, the staff clamps the two guide frames 63 on the lowermost tower drum, and splices the two guide frames 63. The fixing mode between the two guide frames 63 is the prior art, which will not be described in detail here. When the two guide frames 63 are assembled in place, each pulley is in contact with the outer surface of the lowermost tower drum. Further, the staff connects the four main hoisting ropes with the tower drum to be hoisted, and moves the sleeve to be hoisted to one side of the guide frame 63, so that the sleeve is located between the two side plates 68. At this time, the staff starts the two second cylinders 69, so that the two second cylinders 69 drive the two second pressing blocks 610 to move synchronously until the two second pressing blocks 610 jointly clamp the tower drum to be hoisted. In this case, the two second pressing blocks 610 can connect the two guide frames 63 with the tower drum to be hoisted. In the process of hoisting the tower drum, the two guide frames 63 move together. When the two guide frames 63 move to the top end of the uppermost tower drum, the staff controls the two second cylinders 69 to retract until the two second pressing blocks 610 are separated from the tower drum in the hoisting process. At this time, the tower drum in the hoisting process can move freely, and the staff can complete the installation of the tower drum. Based on the above process, when the tower drum is hoisted, the tower drum can be limited by the two guide frames 63 before it moves to the installation position, so as to avoid the phenomenon that the tower drum shakes in the hoisting process. In addition, the plurality of rollers 64 on the two guide frames 63 can reduce the friction between the two guide frames 63 and the tower drum, so as to facilitate the movement of the two guide frames 63 along the installed tower drum. Furthermore, the two guide frames 63 can not only move up and down, but also rotate freely.

[0053] Before the two guide frames 63 are separated from the tower drum to be installed, the staff starts the two first cylinders 66, so that the two first cylinders 66 drive the two first pressing blocks 67 to move synchronously until the two first pressing blocks 67 jointly press the outer surface of the tower drum. At this time, the two first pressing blocks 67 jointly fix the two guide frames 63, so as to avoid the two guide frames 63 from falling down under the action of gravity. When the two guide frames 63 are lowered, the staff controls the two first cylinders 66 to retract, so that the two first pressing blocks 67 are separated from the tower drum, and the second traction equipment 61 slowly releases the traction rope 62, so that the two guide frames 63 slowly descend.
