Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing of wind power tower frames, and particularly relates to a weld heat preservation device. Background Art

[0002] Wind power generation is to convert the kinetic energy of wind into electric energy. Wind energy is a clean, pollution-free and renewable energy source. Using wind energy for power generation has the characteristics of being pollution-free, renewable and technically mature, and the wind energy reserve is huge. Therefore, it has been increasingly valued by countries around the world.

[0003] With the development of wind turbines towards large-scale, the tower frame materials designed by each design party are also developing towards high strength. In order to ensure the welding quality of high-strength materials, a series of process measures must be taken to ensure the welding quality.

[0004] However, the existing welds have too fast a cooling rate, which may cause the gas protection effect to be damaged, and defects such as porosity are likely to occur. At the same time, too fast a welding speed will also accelerate the cooling rate of the weld metal, reduce the plasticity and toughness of the weld metal, and lead to poor forming.

[0005] In order to solve this technical problem, the utility model proposes a weld heat preservation device. Content of the Utility Model

[0006] The main purpose of the utility model is to provide a weld heat preservation device, which can effectively solve the problems mentioned in the background art.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] The weld heat preservation device includes a strong magnet. A fixing block is connected to the side end of the strong magnet. A connection groove is opened in the fixing block. A connection head is rotatably connected in the connection groove. An adjusting threaded rod is connected to the side end of the connection head. A moving threaded ring is threadedly connected to the outer end of the adjusting threaded rod. A pressing plate is connected to the side end of the moving threaded ring. A heat preservation cotton is connected to the side end of the pressing plate.

[0009] Preferably, the strong magnet is adsorbed on the outer shell steel plate of the wind power tower frame. The adjusting threaded rod is rotatably connected in the fixing block. A threaded groove is opened inside the moving threaded ring.

[0010] Preferably, the pressing plate is located at the side end of the steel plate weld. The heat preservation cotton is in contact with the steel plate surface and the steel plate weld.

[0011] Preferably, a first rotating handle is connected to the side end of the adjusting threaded rod. A groove is opened on the outer surface of the connection head.

[0012] Preferably, a fixed threaded ring is connected to the outer end of the fixed block. A threaded groove is provided inside the fixed threaded ring. The fixed threaded ring communicates with the connecting groove. A fixed threaded rod is connected to the fixed threaded ring in a threaded manner.

[0013] Preferably, the fixed threaded rod is rotatably connected inside the fixed block. The side end of the fixed threaded ring is an arc surface. A convex strip is connected to the arc surface side end. The convex strip can be connected to the groove on the surface of the connecting head.

[0014] Preferably, a second rotating handle is connected to the side end of the fixed threaded rod.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the utility model, by arranging a strong magnet, the device can be adsorbed and connected to the outer shell steel plate of the wind power tower. By arranging an adjusting threaded rod and a moving threaded ring, rotating the first rotating handle can drive the adjusting threaded rod to rotate, so as to act on the moving threaded ring, thereby driving the moving threaded ring to move, and then driving the pressing plate to move, so that the pressing plate pushes the heat preservation cotton, making the heat preservation cotton tightly fit on the steel plate and the steel plate weld, so as to insulate the steel plate weld, thereby reducing the cooling speed after welding of the weld and reducing welding defects, and effectively ensuring the welding quality.

[0017] In the utility model, by arranging a fixed threaded ring and a fixed threaded rod, after the heat preservation cotton is attached to the steel plate weld, rotating the second rotating handle will drive the fixed threaded rod to rotate. The rotation of the fixed threaded rod acts on the fixed threaded ring, enabling the fixed threaded rod to move within the fixed threaded ring, so that the side end of the fixed threaded rod can be connected to the connecting head, thereby being able to squeeze and fix the connecting head, and thus fix the adjusting threaded rod to prevent it from accidentally rotating and causing the heat preservation cotton to separate from the steel plate weld. The device has a simple structure, simple operation, good fixing effect and strong stability, and can effectively insulate the steel plate weld. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] As Figures 1-5 shown, the weld heat preservation device includes a strong magnet 1, and the strong magnet 1 is adsorbed on the outer shell steel plate of the wind power tower, so that the device can be fixed. A fixed block 2 is connected to the side end of the strong magnet 1. A connecting groove 3 is opened in the fixed block 2. A connecting head 4 is rotatably connected in the connecting groove 3. The side end of the connecting head 4 is connected with an adjusting screw rod 5. The connecting head 4 is rotatably connected in the connecting groove 3, which can prevent the adjusting screw rod 5 from falling off the fixed block 2, can facilitate the rotation of the adjusting screw rod 5, and can make the adjusting screw rod 5 rotate stably.

[0026] The adjusting screw rod 5 is rotatably connected in the fixed block 2. A first rotating handle 9 is connected to the side end of the adjusting screw rod 5. The first rotating handle 9 can facilitate the rotation of the adjusting screw rod 5. The outer end of the adjusting screw rod 5 is threadedly connected with a moving thread ring 6. A thread groove is opened inside the moving thread ring 6. A pressing plate 7 is connected to the side end of the moving thread ring 6. A heat preservation cotton 8 is connected to the side end of the pressing plate 7. The pressing plate 7 is located at the side end of the steel plate weld, and the heat preservation cotton 8 is attached to the steel plate surface and the steel plate weld.

[0027] A fixed thread ring 10 is connected to the outer end of the fixed block 2. A thread groove is opened inside the fixed thread ring 10. The fixed thread ring 10 is communicated with the connecting groove 3. A fixed screw rod 11 is threadedly connected in the fixed thread ring 10. A second rotating handle 12 is connected to the side end of the fixed screw rod 11. The second rotating handle 12 can facilitate the rotation of the fixed screw rod 11. The fixed screw rod 11 is rotatably connected in the fixed block 2. A groove is opened on the outer surface of the connecting head 4. The side end of the fixed thread ring 10 is set as an arc surface, and a convex strip is connected to the arc surface side end. This convex strip can be connected to the groove on the surface of the connecting head 4, so that the fixed screw rod 11 can be connected to the connecting head 4, thereby being able to squeeze and fix the connecting head 4, and thus fix the adjusting screw rod 5.

[0028] When using this device, it is adsorbed on the steel plate by the strong magnet 1, so that the pressing plate 7 is located at the side end of the steel plate weld. Then rotate the first rotating handle 9 to drive the adjusting screw rod 5 to rotate. The rotation of the adjusting screw rod 5 acts on the moving threaded ring 6, which will drive the moving threaded ring 6 to move, thereby driving the pressing plate 7 to move, so that the pressing plate 7 pushes the heat preservation cotton 8, making the heat preservation cotton 8 tightly fit at the steel plate weld, so as to insulate the steel plate weld. Then rotate the second rotating handle 12 to drive the fixed screw rod 11 to rotate. The rotation of the fixed screw rod 11 acts on the fixed threaded ring 10, which will make the fixed screw rod 11 move within the fixed threaded ring 10, so that the side end of the fixed screw rod 11 can be connected to the connector 4, thereby squeezing and fixing the connector 4, and thus the adjusting screw rod 5 can be fixed, so as to fix the position of the pressing plate 7.
