Description

Technical Field

[0001] This utility model belongs to the field of cylindrical support technology, specifically relating to an adjustable roundness support device for cylindrical bodies. Background Technology

[0002] A wind turbine tower is the support structure for wind power generation. It primarily supports the wind turbine generator set and absorbs vibrations. The general manufacturing process for wind turbine towers is as follows: CNC cutting machine cuts the material; thick plates require beveling; plate rolling machine rolls the plate into shape; spot welding is performed; positioning is confirmed; and then the inner and outer longitudinal seams are welded. Roundness is checked, and if any issues are found, a second rounding is performed. After each section of the tower is welded, a hydraulic assembly roller frame is used for spot welding. The inner and outer circumferential seams are then welded, and straightness and other tolerances are checked. After welding the flanges, non-destructive testing and flatness checks are performed on the welds. After sandblasting and painting, the internal components are installed, and the finished product is inspected before being transported to the installation site.

[0003] In the manufacturing industries of chemical towers, wind turbine towers, and other similar products, the cylinder body is the largest component. Due to its own weight and insufficient rigidity, the roundness of the cylinder body may deviate to a certain extent. It is necessary to use internal support fixtures to ensure roundness. Different projects use cylinder bodies made of steel plates of different thicknesses and with different diameters, resulting in a wide variety of cylinder body specifications and a large number of cylinder body supports required, which leads to huge manufacturing tooling costs. In the existing technology, a cross-shaped integral structure support method is often used, but this support method has limited versatility, consumes a lot of tooling materials, and is not convenient to operate. Therefore, there is an urgent need for a practical and easy-to-assemble adjustable roundness support device for cylinder bodies. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] like Figures 1 to 7 As shown, this utility model discloses an adjustable roundness support device for a cylinder. Multiple adjustable roundness support devices are disposed within the cylinder 100. The specific number of adjustable roundness support devices used needs to be set according to the actual working conditions such as the size and thickness of the cylinder 100 during actual use. The adjustable roundness support device for the cylinder includes a first support section 1, a second support section 2 disposed at one end of the first support section 1, and a second support section 2 disposed at the other end of the first support section 1. The first support section 1 includes a first pipe fitting 12, a plug 11 connected to one end of the first pipe fitting 12, and a socket 13 connected to the other end of the first pipe fitting 12. Both the plug 11 and the socket 13 are made of round steel. The plug 11 has multiple threaded holes, and the socket 13 has a through hole matching the threaded holes. The bottom of the socket 13 has a slot matching the plug 11, and a fastener 14 is disposed in the through hole. When multiple first support sections 1 need to be connected to each other according to the working conditions, they can be connected by inserting the plug 11 into the slot, and then the fastener 14 can be fixed by passing through the threaded hole and the through hole in sequence. The second support section 2 includes an adjusting nut 22, a second pipe fitting 21 and a third pipe fitting 23 respectively set at both ends of the adjusting nut 22. The second pipe fitting 21 and the adjusting nut 22, and the third pipe fitting 23 and the adjusting nut 22 are threaded connections. More specifically, fine-pitch triangular thread connection is used. A round hole is opened through the middle of the adjusting nut 22. The overall length of the second support section 2 can be increased or decreased by inserting a wrench into the round hole and turning the adjusting nut 22. The free end of the second pipe fitting 21 is provided with a plug 11. The structure of the plug 11 is the same as above and will not be described again here. The third support section 3 includes a fourth pipe fitting 31 and a socket 13 set at one end of the fourth pipe fitting 31. The structure of the socket 13 is the same as above and will not be described again here.

[0027] In one specific embodiment, in the adjustable roundness support device for the cylinder of this utility model, the plug 11 is connected to the first pipe 12 and the second pipe 21 by welding, and the connector 13 is connected to the first pipe 12 and the fourth pipe 31 by welding. Of course, other integrated connections can also be used, which are not limited here.

[0028] In one specific embodiment, in the adjustable roundness support device for the cylinder of this utility model, a gasket is welded between the fastener 14 and the connector 13. After the fastener 14 is fully screwed into the threaded hole, the connector 13, the gasket, and the fastener 14 can be fixed for a second time by spot welding, so that the connection between each support section is more stable and tighter.

[0029] In one specific embodiment, in the adjustable roundness support device for the cylinder of this utility model, the fastener 14 is a fastening bolt. Of course, the fastener 14 can also be other fasteners such as screws and rivets, as long as the fastening effect is met. The thread of the fastening bolt does not exceed the bottom of the connector 13, effectively preventing the fastener thread from being damaged by impact.

[0030] In one specific embodiment, in the adjustable roundness support device for the cylinder of this utility model, the top of the receiving joint 13 is provided with two correspondingly distributed arc-shaped plates, and there is a window between the two arc-shaped plates, which can facilitate the use of a ratchet wrench to tighten the fastener 14.

[0031] In one specific embodiment, the adjustable roundness support device for the cylinder of this utility model has 2 to 4 threaded holes and 2 round holes. More specifically, the number of threaded holes and 2 round holes are both corresponding in position and size.

[0032] The working principle of the adjustable roundness support device for cylinder of this utility model is as follows: When the inner diameter of the cylinder 100 is small, the two ends of the first support section 1 can be fixed with the second support section 2 and the third support section 3 respectively by fasteners 14. Then, the whole device is placed inside the cylinder 100, and the length of the second support section 2 can be adjusted by rotating the adjusting nut 22 so that the device can achieve the support effect for the cylinder 100.

[0033] When the inner diameter of the cylinder 100 is large, the number of the first support section 1 can be increased according to the actual working conditions so that the device can achieve the supporting effect on the cylinder 100.

[0034] In summary, compared with the prior art, the adjustable roundness support device for cylinders of this utility model has the following advantages and beneficial effects:

[0035] This device has a simple structure and is easy to assemble and disassemble. It adopts a modular structure, which can be assembled into any length. It is highly applicable, uses readily available materials, and has low manufacturing costs. The cylinder 100 support can adjust the roundness of the cylinder 100, which is convenient for construction operations. Each support section is initially fixed with fasteners 14, and then the connector 13, gasket, and fasteners 14 are spot-welded for secondary fixation, making the connection between each support section more stable and secure. This device has good practicality and safety.
