Description

TECHNICAL FIELD

[0001] The application relates to the technical field of wind power tower drums, in particular to a tower drum flange anti-deformation supporting structure. BACKGROUND

[0002] The flange is a very important component in the wind power tower drum, and the flange connection is to fix two adjacent ends of the tower drums on a flange plate respectively, and then connect the two flange plates by bolts to make them tightly combined. Since the flange connection has the advantages of stable connection, convenient use, strong sealing and the ability to withstand large pressure, it is widely used in industrial manufacturing and plays an irreplaceable role.

[0003] Since the tower drum has a large volume and weight, the flanges welded at the two ends of the tower drum may be deformed during storage and transportation, which affects the use, causes economic losses and has certain safety hazards. The existing two-character and three-character flange anti-deformation supporting tools can prevent the flange from deforming to a certain extent during transportation, but they are not very versatile, have high manufacturing costs and poor safety, and when supporting the flanges of tower drums of different sizes, customized supporting tools are needed, which increases the workload and manufacturing costs. Therefore, further improvement is needed. CONTENT OF THE UTILITY MODEL

[0004] In order to meet the strengthened use of tower drum flanges of different sizes, the application provides a tower drum flange anti-deformation supporting structure.

[0005] The application provides a tower drum flange anti-deformation supporting structure which adopts the following technical scheme:

[0006] A tower drum flange anti-deformation supporting structure comprises a supporting plate coaxially arranged on a tower drum and a plurality of supporting arms arranged around the axis of the supporting plate, and the axial direction of the supporting arms is parallel to the radial direction of the tower drum.

[0013] By adopting the above technical scheme, the support rod is designed as a threaded rod, which cooperates with the adjusting nut. By rotating the adjusting nut, the support rod in the support pipe can be accurately adjusted, ensuring that the length of the support arm can be flexibly adjusted according to actual needs, adapting to flanges of different diameters, and improving the universality and application range of the device.

[0014] Preferably, the end of the support pipe in which the support rod is arranged is fixedly connected with a movable plate, and the support pipe is arranged with a spring, one end of the spring is fixedly connected to the movable plate, and the spring is in a compressed state.

[0016] Preferably, a reinforcing arm is arranged between the two adjacent support pipes.

[0017] By adopting the above technical scheme, the reinforcing arm is arranged between the two adjacent support pipes, effectively enhancing the rigidity and stability of the entire support structure and improving the ability of the support structure to resist external impact.

[0018] Preferably, the side wall of the support pipe is fixedly connected with a first lug plate, one end of the reinforcing arm is fixedly connected with a second lug plate abutting against the first lug plate, the first lug plate and the second lug plate are both provided with a pin hole, and the first lug plate and the second lug plate are provided with a reinforcing bolt penetrating through the pin hole.

[0019] By adopting the above technical scheme, the first lug plate fixedly connected with the side wall of the support pipe and the second lug plate fixedly connected with one end of the reinforcing arm abut against each other and are fixed by the reinforcing bolt in the pin hole, so that the connection strength between the support arms is enhanced and the stability of the entire support structure is improved.
