Since the wind speed is high in high-altitude areas when wind turbines are installed, and the installation environment with a small wind speed is required during the installation of wind turbines. Specifically, the wind speed requirement is less than 10 m / s during the hoisting of components. Therefore, the installation environment in high-altitude areas brings uncertainty to the installation process of wind turbines, seriously affecting the installation efficiency and construction progress. Therefore, a self-lifting auxiliary installation equipment that climbs on the tower barrel is needed to connect the components to be hoisted with the self-lifting auxiliary installation equipment, so as to ensure the stable hoisting of the components to be hoisted.

One side of the friction block 9 is a friction surface, and a roller 8 is rotatably installed on the other side; A connecting rod 7 for connecting the components to be hoisted is installed on the upper ring seat 1 and / or the lower ring seat 4.

[0025] The present utility model pushes the friction block 9 through the push rod 2 so that the friction surface abuts against the tower barrel, and the stability is good. In addition, during the lifting operation, the friction block 9 on one side of the ring seat abuts against the tower barrel, and the friction block 9 on the other side of the ring seat flips so that the roller 8 abuts against the tower barrel, and then the installation device is lifted by the telescopic movement of the telescopic member 3. The whole process has good stability.

[0026] In this embodiment, refer to Figure 4 , 6 , the sliding seat 12 has a U-shaped groove structure. The mounting hole is a rectangular hole that mates with the sliding seat 12. The telescopic end of the push rod 2 is fixedly connected to the internal thread sleeve of the sliding seat 12 through a thread.

[0027] In this embodiment, refer to Figure 2 , the upper ring seat 1 and the lower ring seat 4 are each composed of at least two segments, and adjacent segments are connected by bolts. Specifically, adjacent segments can be bolted together through a flange structure, or the mortise and tenon structure 11 in Figure 4 can be used for connection. The bolt 5 passes through the mortise structure 11 to form the upper ring seat 1 and the lower ring seat 4. Through the above structure, it is convenient to install the upper ring seat 1 and the lower ring seat 4 around the tower barrel.

[0028] In this embodiment, four mounting holes are respectively provided on the upper ring seat 1 and the lower ring seat 4. That is to say, four push rods 2 and four friction blocks 9 are respectively installed on the upper ring seat 1 and the lower ring seat 4.

[0029] In this embodiment, the telescopic member 3 is a hydraulic cylinder or an electric cylinder or a pneumatic cylinder.

[0030] In this embodiment, the push rod 2 is a hydraulic cylinder or an electric cylinder or a pneumatic cylinder.

[0031] Refer to Figure 5 , the connecting rod 7 is a hydraulic cylinder or an electric cylinder or a pneumatic cylinder.

[0032] Refer to Figure 6 , the friction block 9 is rotatably connected to the sliding seat 12 through a rotating shaft 13. A driver 14 is installed on the sliding seat 12, and the driver 14 is in transmission connection with the rotating shaft 13 to drive the friction block 9 to flip through the driver 14. Through the drive of the driver 14, the friction block 9 flips. When the friction surface abuts against the tower barrel, the ring seat is fixed to the tower barrel. When the roller 8 abuts against the tower barrel, the ring seat supports and rolls on the tower barrel. In this embodiment, the driver 14 is a motor or a hydraulic motor. The friction block 9 is fixedly connected to the rotating shaft 13. One end of the rotating shaft 13 is provided with a spline hole, and the output shaft of the driver 14 is a spline shaft, and the spline shaft is inserted into the spline hole. A groove is provided on the other side of the friction block 9, and the roller 8 is rotatably installed in the groove through a central shaft.

[0033] The working principle or operation process of the present utility model is as follows:

[0034] When the wind power generation equipment is installed, after the installation of the first section of the tower barrel of the wind power generation, that is, the tower barrel base, first install the lower ring seat 4 on the tower barrel base. The lower ring seat 4 is composed of two semi - circles connected by a mortise - tenon structure 11 and bolts 5. Then, four telescopic members 3 can be installed. Install the upper ring seat 1 on the top of the telescopic member 3. The upper ring seat 1 is also composed of two semi - circles connected by a mortise - tenon structure 11 and bolts 5. Both ends of the telescopic member 3 can be bolt - connected to the upper ring seat 1 and the lower ring seat 4 through end plates. When the push rod 2 and the telescopic member 3 adopt hydraulic cylinders, the push rod 2 and the telescopic member 3 are respectively connected to the hydraulic power and control system through hydraulic hoses.

[0035] During use, first rotate and adjust the friction block 9 in the upper ring seat 1. When the friction surface is in full contact with the tower barrel base, the upper - ring hydraulic lifting base 1 is locked and fixed to the tower barrel base. Immediately afterwards, rotate and adjust the friction block 9 of the lower ring seat 4. When the roller 8 is in full contact with the tower barrel base, the lower ring seat 4 is in rolling contact with the tower barrel base.

[0036] After that, the telescopic member 3 contracts and shortens, causing the lower ring seat 4 to climb upward. During the upward climb of the lower ring seat 4, the roller 8 of the lower ring seat 4 always maintains rolling contact with the tower barrel base. On the one hand, it greatly reduces the frictional resistance during climbing. On the other hand, it ensures that the force on the tower barrel is in a straight line, thereby greatly reducing the bending moment and effectively improving the safety and stability of transportation. After climbing a certain height, the push rods 2 in the lower ring seat 4 are grouped in pairs of two opposite ones. The grouped push rods 2 retract in sequence, causing the friction block 9 to retreat a certain distance, and the roller 8 is separated from the tower barrel base. Rotate and adjust the friction block 9 of the lower ring seat 4 again, and rotate the combination of the friction surface and the roller 8 by 180 degrees so that the friction surface faces the tower barrel base. The push rod 2 advances a certain distance towards the tower barrel base, and the friction surface of the friction block 9 is in full contact with the tower barrel base, causing the lower ring seat 4 to be locked and fixed to the tower barrel base.

[0037] Then, conversely, the push rods 2 in the upper ring seat 1 are grouped in pairs of two opposite ones. The grouped push rods 2 retract a certain distance in sequence, and the friction surface of the friction block 9 is separated from the tower barrel base. Similarly, rotate and adjust the friction block 9 in the upper ring seat 1, and rotate the combination of the friction surface and the roller 8 by 180 degrees so that the roller 8 faces the tower barrel base. The push rod 2 advances a certain distance towards the tower barrel base, and the roller 8 is in full contact with the tower barrel base. At this time, the upper ring seat 1 is in a rolling relationship with the tower barrel base.

[0038] Finally, the telescopic member 3 extends, and the upper ring seat 1 climbs upward. Among them, the connecting rod 7 is always firmly fixedly connected to the tower barrel or the generator set to be hoisted.

[0039] Through the above technical solution, just like this, through the continuous cyclic cooperation among the upper ring seat 1, the lower ring seat 4, the telescopic member 3, the push rod 2, the friction block 9 and the roller 8, under the lifting of the crane, the self-lifting auxiliary installation equipment of the wind turbine of the present utility model and the components to be hoisted continuously climb upward stably. At the same time, the connecting rod 7 is always firmly fixedly connected to the tower barrel or the generator set to be hoisted. With the cooperation of the crane, it is not affected by the wind force, so that the hoisting process does not shake and the whole process has good stability.
