Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing of offshore wind power tower frames, and particularly relates to an anti-tipping bracket for a large-diameter single-section cylinder. Background Art

[0002] With the development of society, green clean energy will become the main energy supply for industries and households. Wind energy is a green clean energy that is renewable, pollution-free, has large energy, and broad prospects. Vigorously investing in the development of wind power will surely become the first choice of major power generation groups.

[0003] The main components of a wind power generation tower barrel are as follows. Generally, the manufacturing process of the tower barrel is as follows: 1. Roll the steel plate into a cylindrical shape, and then connect the two sides of the steel plate by welding to form a single-section cylinder; 2. Connect multiple single-section cylinders axially by welding to form a tower barrel.

[0004] In order to facilitate rolling of the plate, narrow steel plates are used for rolling. However, the single-section cylinder rolled from the narrow steel plate has a small height and a large diameter, resulting in a relatively high center of gravity and a small contact area with the ground when the single-section cylinder is placed horizontally. During the welding process, due to rotation and unstable center of gravity, it is prone to tipping, which may cause production accidents. Content of the Utility Model

[0005] In order to overcome the deficiencies of the above-mentioned prior art, the purpose of the utility model is to provide an anti-tipping bracket for a large-diameter single-section cylinder, which enhances the safety performance of the single-section cylinder during the longitudinal seam welding process, prevents tipping accidents during the rotation process, and improves the safety performance of production.

[0006] The first technical solution of the utility model is as follows:

The mounting seat is arranged on the bottom plate, the roller is rotatably arranged on the mounting seat, the motor is arranged on the mounting seat, and the motor is drivingly connected to the roller.

[0009] Furthermore, the motor is provided with a reduction box.

[0010] As a preferred solution, the anti-tipping component includes two limiting frames, and the two limiting frames are arranged on the bottom plate at intervals along the axial direction of the single-section cylinder.

[0011] Furthermore, the anti-tipping component further includes a connecting rod, and the connecting rod connects the two limiting frames.

[0012] Further, the anti-tilting assembly further includes an auxiliary wheel, which is rotatably arranged on the connecting rod and located on one side of the connecting rod close to the single-section cylinder.

[0013] Further, the height position of the auxiliary wheel is lower than the radius length of the single-section cylinder.

[0014] Further, the anti-tilting assembly further includes a driver. One end of the limiting frame is hinged to the bottom plate, and the driver is drivingly connected to the limiting frame.

[0015] Further, the driver is a hydraulic cylinder. The hydraulic cylinder is located outside the limiting frame. One end of the hydraulic cylinder is hinged to the bottom plate, and the other end is hinged to the limiting frame or the connecting rod.

[0016] Further, there are two hydraulic cylinders, and each hydraulic cylinder is drivingly connected to a corresponding limiting frame.

[0027] As Figures 1-4 shown, this embodiment provides a large-diameter single-section cylinder anti-tipping bracket, including a bottom plate 1, a pair of support assemblies 2, and a pair of anti-tipping assemblies 3. The two support assemblies 2 are spaced apart on the bottom plate 1 and are used to support the single-section cylinder; the two anti-tipping assemblies 3 are oppositely arranged on the bottom plate 1 and are located outside the two support assemblies 2 for axially limiting the single-section cylinder. The rolled steel plates (and the un-welded single-section cylinders) are placed on this bracket, and the safety performance during the longitudinal seam welding process is improved, preventing it from tipping over during the rotation process and enhancing the safety performance of production.

[0028] As Figure 4As shown, as a preferred solution, the support assembly 2 includes a mounting base 21, rollers 22 and a motor 23. The mounting base 21 is arranged on the bottom plate 1. The rollers 22 are rotatably arranged on the mounting base 21. The motor 23 is arranged on the mounting base 21. The motor 23 is drivingly connected to the rollers 22. By driving the rollers 22 to rotate with the motor 23, the single-section cylinder is driven to rotate along its axis to adjust the positions of the inner and outer surfaces of the cylinder, facilitating workers to carry out welding or other process treatments on the inner and outer surfaces of the single-section cylinder.

[0029] Furthermore, the motor 23 is equipped with a reduction gearbox to increase the torque of the motor 23, which is beneficial for driving the single-section cylinder to rotate.

[0030] As Figures 1-3 As shown, as a preferred solution, the anti-tipping assembly 3 includes two limiting frames 31. The two limiting frames 31 are arranged on the bottom plate 1 at intervals along the axis of the single-section cylinder to limit both sides of the axis of the single-section cylinder and prevent the single-section cylinder from tipping over from both sides of its axis.

[0031] Furthermore, the anti-tipping assembly 3 further includes a connecting rod 32. The connecting rod 32 connects the two limiting frames 31 to improve the stability of the anti-tipping assembly 3.

[0032] Furthermore, the anti-tipping assembly 3 further includes an auxiliary wheel 33. The auxiliary wheel 33 is rotatably arranged on the connecting rod 32 and is located on the side of the connecting rod 32 close to the single-section cylinder. When the single-section cylinder rotates, the auxiliary wheel 33 can assist the rotation of the single-section cylinder and at the same time avoid rubbing between the outer surface of the single-section cylinder and the connecting rod 32.

[0033] Furthermore, the height position of the auxiliary wheel 33 is lower than the radius length of the single-section cylinder. In this way, the single-section cylinder can be supported to ensure the roundness of the single-section cylinder during the welding construction process.

[0034] Furthermore, the anti-tipping assembly 3 further includes a driver 34. One end of the limiting frame 31 is hinged to the bottom plate 1. The driver 34 is drivingly connected to the limiting frame 31. In this way, according to the diameter length of different single-section cylinders, the angle of the limiting frame 31 and the position of the auxiliary wheel 33 are adjusted through the hydraulic cylinder, improving the versatility.

[0035] Furthermore, the driver 34 is a hydraulic cylinder. The hydraulic cylinder is located outside the limiting frame 31. One end of the hydraulic cylinder is hinged to the bottom plate 1, and the other end is hinged to the limiting frame 31 or the connecting rod 32. A triangular support structure is formed among the limiting frame 31, the hydraulic cylinder and the bottom plate 1, which can provide its stability.

[0036] Further, there are two hydraulic cylinders, and each hydraulic cylinder is drivingly connected to a corresponding limit frame 31; the two hydraulic cylinders are driven synchronously to improve the supporting force when the auxiliary wheel 33 holds and supports a single cylinder.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
