Technical Field

[0001] The utility model relates to the technical field of wind power tower manufacturing, in particular to a double-sided grinding device for a bevel thinning surface. Background Art

[0002] Wind power generation converts the kinetic energy of wind into electrical energy and is an important component of renewable resources.

[0003] A wind turbine tower is composed of multiple cylinder sections. Generally, each single cylinder section is a steel plate. According to the production process, after entering the factory, the steel plate generally needs to go through processes such as cutting and beveling to be manufactured into a single cylinder section. When the single cylinder section is assembled, thick plates and thin plates will be connected, so the thick plates need to be thinned.

[0004] During production, the thinned surface will be treated by grinding to remove the oxide scale. However, the existing operation is to grind one side first, then flip the steel plate through the combination of a crane and a clip, and then grind the other side. This method not only reduces production efficiency, but the clip will also cause certain damage to the steel plate. It has low work efficiency, poor flexibility and low practicality.

[0005] In order to solve this technical problem, the utility model proposes a double-sided grinding device for the thinned surface of a groove. Utility Model Content

[0006] The main purpose of the utility model is to provide a double-sided grinding device for the thinned surface of a bevel, which can effectively solve the problems mentioned in the background technology.

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

[0008] A double-sided grinding device for the thinned surface of a bevel comprises a movable trolley, a connecting rod being connected to the side end of the movable trolley, a first threaded rod and a second threaded rod being rotatably connected inside the connecting rod, the mechanisms arranged at the side ends of the first threaded rod and the second threaded rod are the same. Taking the first threaded rod as an example: a connecting ring is rotatably connected to the outer end of the first threaded rod, a support rod is connected to the outer end of the connecting ring, a grinder is connected to the side end of the support rod, a grinding disc is provided at the driving end of the grinder, a threaded ring is connected to the outer end of the connecting ring, and the inner thread of the threaded ring is connected to the fixed threaded rod.

[0009] Preferably, a handle is provided at the side end of the moving trolley, and the directions of the first threaded rod and the second threaded rod are perpendicular to the moving direction of the moving trolley.

[0010] Preferably, the outer end of the connecting rod is connected to a threaded tube, a threaded groove is opened in the threaded tube, the first threaded rod and the second threaded rod are threadedly connected in the threaded tube, and the side ends of the first threaded rod and the second threaded rod are connected to rotating parts.

[0011] Preferably, the outer end of the connecting rod is connected to a restraining ring, the connecting ring is rotatably connected inside the restraining ring, and a groove is provided between the restraining rings.

[0012] Preferably, a threaded groove is provided in the threaded ring, the threaded ring is communicated with the connecting ring, and the fixed threaded rod is rotatably connected in the connecting ring.

[0013] Preferably, the side end of the fixed threaded rod is connected with a round handle, the side end of the fixed threaded rod is set as an arc surface, the arc surface side end is connected with a convex strip, and the convex strip can be connected with the groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the utility model, a first threaded rod and a second threaded rod are provided, and grinders and grinding discs are provided at the side ends of both. The position of the grinder at the side end can be adjusted by rotating the first threaded rod and the second threaded rod, and the inclination angle of the grinder can be adjusted by providing a connecting ring, so that the two grinding discs can grind both sides of the steel plate respectively. By providing a movable trolley, workers can use the handle to control the movable trolley to grind back and forth, so as to completely remove impurities such as oxide scale on the thinned surface. The device has a simple structure, easy operation and high flexibility. It can be used for steel plates of different thicknesses and can grind both sides of the thinned surface of the groove at the same time. There is no need to flip the steel plate through a crane and a snap fit. While improving production efficiency, it also reduces quality problems of the steel plate, and its practicality is high.

[0016] In the utility model, a threaded ring and a fixed threaded rod are provided. After the position and angle of the grinder are determined, the fixed threaded rod is rotated by the circular handle. The fixed threaded rod rotates and acts on the threaded ring, which will enable the fixed threaded rod to move inside the threaded ring and the connecting ring. In this way, the convex strips on the side ends of the fixed threaded rods can be connected with the grooves, thereby fixing the connecting ring and preventing the angle of the grinder from changing when the equipment is running. The device has good stability and can effectively improve the safety of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-6 As shown, a double-sided grinding device for bevel thinning surface includes a mobile trolley 1, a handle 11 is provided at the side end of the mobile trolley 1, and the handle 11 can facilitate the staff to drive the mobile trolley 1 to move, and a connecting rod 2 is connected to the side end of the mobile trolley 1. A first threaded rod 3 and a second threaded rod 4 are rotatably connected in the connecting rod 2. The connecting rod 2 is used to support and connect the first threaded rod 3 and the second threaded rod 4. The directions of the first threaded rod 3 and the second threaded rod 4 are perpendicular to the moving direction of the mobile trolley 1. The first threaded rod 3, the second threaded rod 4 and the mechanisms at the side ends of the two are all arranged symmetrically.

[0026] The outer end of the connecting rod 2 is connected to a threaded tube 12, and a threaded groove is opened in the threaded tube 12. The first threaded rod 3 and the second threaded rod 4 are threadedly connected in the threaded tube 12. The threaded tube 12 can support the first threaded rod 3 and the second threaded rod 4. The side ends of the first threaded rod 3 and the second threaded rod 4 are connected to a rotating part 13. The rotating part 13 can easily drive the first threaded rod 3 and the second threaded rod 4 to rotate. The rotation of the two will respectively act on the threaded tube 12 at their outer ends, and will be able to drive the grinding equipment at the side ends to move respectively.

[0027] The mechanisms set at the side ends of the first threaded rod 3 and the second threaded rod 4 are the same. Take the first threaded rod 3 as an example: the outer end of the first threaded rod 3 is rotatably connected to the connecting ring 5, the outer end of the connecting rod 2 is connected to the constraint ring 14, the connecting ring 5 is rotatably connected in the constraint ring 14, the constraint ring 14 is used to support and constrain the connecting ring 5, so that it cannot move and can only rotate, thereby ensuring the stability of the connecting ring 5, the outer end of the connecting ring 5 is connected to the support rod 6, the side end of the support rod 6 is connected to the grinder 7, the support rod 6 is used to support and fix the grinder 7, and the driving end of the grinder 7 is provided with a grinding plate 8.

[0028] The outer end of the connecting ring 5 is connected to a threaded ring 9, and a threaded groove is provided in the threaded ring 9. The threaded ring 9 is communicated with the connecting ring 5. The internal thread of the threaded ring 9 is connected to the fixed threaded rod 10, and the fixed threaded rod 10 is rotatably connected in the connecting ring 5.
