Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and in particular to a device and method for quickly positioning and installing a wind power tower. Background Art

[0002] The wind turbine tower is the tower pole of wind power generation. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the set. The production process of the tube section of the wind turbine tower is generally as follows: the CNC cutting machine cuts the material, the thick plate needs to be beveled, the plate rolling machine rolls the plate into shape, spot welds, positions, and confirms the welding of the inner and outer longitudinal seams. After the roundness is checked, if there is a problem, a second rounding is performed. After the single-section cylinder is welded, the hydraulic group is used to assemble the roller frame for spot welding, the inner and outer circumferential seams are welded, and the straightness and other tolerances are checked. After the flange is welded, non-destructive testing and flatness inspection of the weld are carried out. After sandblasting and painting, the internal parts are installed and the finished product is inspected, and then it is transported to the installation site.

[0003] Wind turbine towers are generally installed by hoisting. During the hoisting process, the cylinder sections are first lifted to a certain height and then moved to the top of the tower. Workers then position and align the tower sections and adjust them as they move downward to prevent them from being misplaced. However, due to the heavy weight of the cylinder sections, position calibration is more laborious. At the same time, the inertia of the cylinder sections is large, which can easily injure workers.

[0004] In order to prevent workers from being injured, some tower tubes are calibrated by manually operating machinery during installation. During operation, multiple installation devices are used to apply force to the outer wall of the tube segment from multiple angles. The thrust generated moves the tube segment for positioning and alignment. However, in actual use, the thrust generated by multiple installation devices needs to be controlled during calibration to prevent the tube segment from being misplaced. The tube segment itself is large in size, and it is difficult for operators to observe the force strength of the installation device from multiple different angles. As a result, the positioning of the tube segment takes a lot of time, affecting the installation efficiency and delaying the construction period. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-5A device for quickly positioning and installing a wind turbine tower includes a climbing frame 1. The climbing frame 1 can be a pipeline robot or other pipeline moving device, and can also be moved up and down with the help of a climbing ladder on the inner wall of the cylinder section. A positioning platform 2 is provided on the climbing frame 1, and a driving structure 3 is provided on the positioning platform 2. Two positioning plates 4 are provided on the driving structure 3. The driving structure 3 includes a driving plate 31. Two connecting rods 32 are rotatably provided on the driving plate 31. The two connecting rods 32 are rotatably connected to the two positioning plates 4 respectively. A rotating seat 5 cooperating with the driving plate 31 is provided on the positioning platform 2, and a driving device 6 dynamically connected to the positioning plate 4 is provided on the positioning platform 2.

[0031] In the present invention, the positioning plate 4 is pushed to move by the driving device 6, which drives the connecting rod 32 to move, so that the angle between the connecting rod 32 and the driving plate 31 changes. The driving plate 31 rotates to drive the other connecting rod 32 to move, and then drives the other positioning plate 4 to move, so that the two positioning plates 4 move synchronously and abut against the inner wall of the cylinder section to support the cylinder section, thereby changing the position of the cylinder section to achieve centering positioning. There is no need to adjust the movement amplitude of each positioning plate 4, so that the cylinder section can be quickly positioned and calibrated. The driving device 6 is preferably an electric telescopic rod.

[0032] Furthermore, in this embodiment, a guide plate 41 is fixedly provided on the positioning plate 4, and the guide plates 41 are all inclined. A support plate 42 is fixedly provided between the guide plate 41 and the positioning plate 4. The two guide plates 41 form a cone-like structure, which is convenient for inserting into the cylinder section to position the cylinder section.

[0033] Furthermore, in this embodiment, a guide rail 21 is fixedly provided on the positioning platform 2, and a guide block 22 is fixedly provided on the positioning plate 4 and is slidably connected to the guide rail 21. The guide rail 21 and the guide block 22 cooperate to limit the moving trajectory of the positioning plate 4 so that it moves in a straight line.

[0034] It should be noted that, in this embodiment, a lifting structure 7 is provided on the climbing frame 1, and the output shaft of the lifting structure 7 is connected to the positioning platform 2. By setting the lifting mechanism 7 to control the position of the positioning platform 2, it is convenient to insert the positioning platform 2 into the cylinder section.

[0035] In this embodiment, the lifting structure 7 includes a sleeve 71, on which a lifting column 72 is movably connected. The lifting column 72 is fixedly connected to the positioning platform 2. The position of the positioning platform 2 can be changed by moving the lifting column 72 up and down in the sleeve 71, and at the same time, it plays the role of controlling the moving trajectory of the positioning platform 2.

[0036] In addition, in this embodiment, a screw rod 73 is rotatably provided in the sleeve 71, and the screw rod 73 is threadedly connected to the lifting column 72. A positioning column 74 is fixedly provided on the outer wall of the lifting column 72, and a corresponding positioning groove is provided on the inner wall of the sleeve. The lifting column 72 is driven up and down by the rotation of the screw rod 73, and the positioning column 74 is provided to prevent the lifting column 72 from rotating with the screw rod 73.

[0037] In this embodiment, a motor 75 is fixedly provided on the climbing frame 1, and a bevel gear 76 is fixedly provided on the output shaft of the motor 75 and the screw rod 73. The two bevel gears 76 are meshed and connected, and the screw rod 73 is driven to rotate by the motor 75 to control the position of the lifting column 72 and the positioning platform 2.

[0038] In detail, in this embodiment, a wear-resistant plate 43 is provided on the guide plate 41, and the wear-resistant plate 43 is connected to the guide plate 41 through a connecting structure 44. The wear-resistant plate 43 is provided to protect the guide plate 41 and prevent the guide plate 41 from being worn after long-term use, resulting in errors in centering and positioning.

[0039] To be more specific, in this embodiment, the connecting structure 44 includes a connecting frame 441 fixedly provided on the guide plate 41, a T-shaped slot is provided on the connecting frame 441, a T-shaped column 442 plugged into the T-shaped slot is fixedly provided on the wear-resistant plate 43, and a positioning glass bead cooperating with the T-shaped column 442 is provided in the T-shaped slot. When the wear-resistant plate 43 receives a downward force, the T-shaped slot supports the T-shaped column 442 and the wear-resistant plate 43, and the ball part of the positioning glass bead is inserted into the T-shaped slot to fix the wear-resistant plate 43. When the wear-resistant plate 43 is forced to move upward, the positioning glass bead is subjected to force. When the force is too large, the ball retracts, thereby allowing the wear-resistant plate 43 to be taken out.

[0040] The present invention also provides a method for quickly positioning and installing a wind turbine tower, comprising the above-mentioned installation device and the following steps:

[0041] S1. Climb upward using the climbing frame 1 to raise the positioning platform 2 to the connection point of the two tower sections;
