Description

Technical Field

[0001] The utility model relates to the technical field of tower production and transportation, in particular to a connecting support member used for tower lifting. Background Art

[0002] Wind turbine towers are the masts of wind turbines, primarily providing support and absorbing vibrations from the turbine. The production process for wind turbine towers includes cutting with a CNC cutting machine, rolling and forming the plates using a plate rolling machine, welding, roundness inspection, sandblasting, and painting. The tower's height must match the length of the blades to ensure greater and more stable wind energy at a higher altitude, thereby improving power generation efficiency and absorbing vibrations from the wind turbine. Wind turbine towers are enormous, often exceeding 10 meters in diameter, and their weight is correspondingly substantial.

[0003] During tower production, lifting operations are required. The traditional method involves hooks or other fasteners attached to the ends of the tower and hoisting it. However, when arranging and lifting towers in large quantities, the existing fixing method requires multiple bolts, which is complex and can only lift the ends of the tower, causing the tower to wobble. When placing the tower, connectors must be frequently disassembled, and there is no place to place the tower to be installed. Placing it directly on the ground would cause the tower to roll.

[0004] In order to solve the above problems, we propose a connecting support for tower lifting. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , the utility model provides a technical solution:

[0023] Embodiment 1: includes a connector housing 1 , a lifting device 2 and a locking device 3 .

[0024] A sleeve is provided on the end face of the connector shell 1, and an inner cavity is provided in the connector shell 1. The locking device 3 is rotatably connected to the inner cavity wall of the connector shell 1, one end of the pulling device 2 is rotatably connected to the side wall of the connector shell 1, and the other end of the pulling device 2 is rotatably connected to the pulling device 2.

[0025] The locking device 3 includes a synchronization device 31 and a locking block 32. One end of the locking block 32 is rotatably connected to the inner cavity wall of the connector housing 1. A movable opening 13 is provided on the side wall of the sleeve of the connector housing 1. The movable opening 13 is connected to the inner cavity of the connector housing 1. The synchronization device 31 is rotatably connected to the inner cavity of the connector housing 1. The end face of the synchronization device 31 is slidably connected to the locking block 32.

[0026] When a worker needs to lift the tower, they first hook the hook onto the lifting device 2 and place the entire connecting support in the desired position. The crane and the worker then work together to secure the connecting support onto the tower. In this utility model, a tower requires at least two connecting supports. As the crane lifts, the lifting device 2 pulls on the synchronizing device 31, causing it to rotate, which in turn drives the locking block 32 to swing, effectively clamping the tower.

[0027] Furthermore, a control post 311 is provided on one end face of the synchronization mechanism 31, and a sliding hole 321 is provided on the side face of the locking block 32. The control post 311 is slidably connected to the sliding hole 321. The control post 311 moves with the synchronization mechanism 31, and the control post 311 also slides in the sliding hole 321, thereby driving the locking block 32 to rotate, achieving opening and closing. The number of locking blocks 32 is the same as the number of control posts 311.

[0028] Furthermore, the sleeve sidewall of the connector housing 1 is provided with a wear-resistant strip. The wear-resistant strip covers the outside of the movable opening 13. The clamping end of the locking block 32 abuts against the inner side of the wear-resistant strip, and when the locking block 32 is clamped, the wear-resistant strip is clamped between the locking block 32 and the tower. In this case, the wear-resistant strip not only increases friction but also prevents damage caused by the rigid connection between the locking block 32 and the tower. When selecting the material for the wear-resistant strip, it is necessary to select a material that is wear-resistant, has high surface friction, and is soft.

[0029] Furthermore, the top surface of the connector housing 1 is provided with a positioning block 11, and the bottom surface of the connector housing 1 is provided with a positioning groove 12. When multiple towers are placed simultaneously, multiple connecting supports can be stacked. Align the positioning block 11 of one connecting support with the positioning groove 12 of another connecting support before placement. Once placed, the towers do not directly touch each other and are neatly arranged, making it easy to lift when needed.

[0030] Furthermore, the lifting device 2 includes a lifting ring 21, a steel rope 22, and a rotating ring 23. The lifting ring 21 is connected to the center of the steel rope 22. One end of the steel rope 22 passes through the side wall of the connector housing 1 and enters the inner cavity to connect to the synchronization device 31. The other end of the steel rope 22 is connected to the rotating ring 23. When multiple towers are stacked, the other end of the steel rope 22 is connected to the rotating ring 23, which does not affect the stacking of multiple connecting supports.

[0031] See also Figure 5 This is the second embodiment of the present utility model.

[0032] Embodiment 2: The technical solution of embodiment 1 is different in that there are two synchronizing devices 31, and the two synchronizing devices 31 are connected by the control column 311. The engagement of the two synchronizing devices 31 makes the entire structure more stable and can withstand greater force.

[0033] Working principle:

[0034] When workers need to lift the tower, they first hook the hook onto the lifting ring 21 and place the entire connecting support in the desired position. The crane and the worker then work together to secure the connecting support onto the tower. As the crane lifts, the lifting ring 21 rises, driving one end of the steel rope 22 to pull on the synchronizing device 31, causing it to rotate. The control column 311 slides within the sliding hole 321, which in turn causes the locking block 32 to swing, effectively clamping the tower.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0036] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
