The main components of this conventional grinder include a scraper and a clamping mechanism. In traditional operations, the steel pipe is first pushed through the scraper by hand, and then the position of the steel pipe is fixed by the clamping mechanism. Finally, the operator manually drags the clamping mechanism to move the steel pipe along the direction of the scraper to achieve a thorough grinding of the steel pipe surface to meet the required wall thickness and smoothness standards. The steel pipe grinding in the prior art still requires the operator to cooperate in the grinding process, and automatic traction cannot be achieved.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Traction device for steel pipe grinding equipment, such as Figure 1 As shown, it includes a long strip-shaped base frame 1, a grinding component, a plurality of supporting components, and two groups of electromagnetic adsorption components. The two groups of electromagnetic adsorption components are respectively fixedly connected to the two ends of the base frame 1, the plurality of supporting components are arranged in the base frame 1, and the grinding component is arranged in the middle position of the top surface of the base frame 1. The two groups of electromagnetic adsorption components are alternately turned on and off.

[0022] like Figure 3 As shown, the support assembly includes a support plate 6 fixedly connected in the base frame 1 and having a V-shaped cross-section, two support wheels 7 rotatably connected to one side of the support plate 6, two rotating shafts rotatably connected to the side of the support plate 6 away from the support wheel 7, and a driving wheel 8 coaxially and fixedly connected to the two rotating shafts, the support wheel 7 is arranged tangent to the supporting surface of the support plate 6, and the two driving wheels 8 are arranged to rotate, a servo motor is fixedly connected in the base frame 1, a driving sprocket is fixedly connected to the output shaft of the servo motor, a driven sprocket is fixedly connected to the rotating shaft, and the driving sprocket and the driven sprocket are connected by a chain transmission.

[0023] like Figure 3 As shown, the grinding assembly includes a mounting frame 9 fixedly connected to the base frame 1, a connecting plate 10 fixedly connected to the mounting frame 9 and located above the base frame 1, a cover 12 fixedly connected to the connecting plate 10 via a connecting frame 11, a driving roller 14 and two transmission rollers 15 located in the cover 12, a frosting belt 16 sleeved on the outside of the driving roller 14 and the transmission roller 15, a driving motor fixedly connected to the base frame 1, a driving wheel fixedly connected to the output shaft of the driving motor, a driving shaft 13 rotatably connected to the connecting plate 10 and passing through the cover 12, a driven wheel fixedly connected to the driving shaft 13, and a transmission belt that drives and connects the driving wheel and the driven wheel, the cover 12 is provided with an opening toward the supporting assembly, the frosting belt 16 exposed from the opening forms a grinding surface, the driving roller 14 is coaxially fixedly connected to the driving shaft 13, and the transmission roller 15 is rotatably connected in the cover 12.

[0024] like Figure 2As shown, a fixing plate 2 is fixedly connected inside the base frame 1, a bearing seat 3 made of plastic is fixedly connected to the fixing plate 2, the electromagnetic adsorption component includes an electromagnet 5, a connecting tube 4, and a brush, the electromagnet 5 is columnar and fixedly connected to the inner ring of the bearing seat 3, the connecting tube 4 is fixedly connected to one end of the two groups of electromagnets 5 facing each other, and the end of the electromagnet 5 away from the connecting tube 4 is electrically connected through a brush.

[0025] When the utility model needs to perform steel pipe grinding work, the operator only needs to manually lift the steel pipe and place it on the support plate 6. The support plate 6 has a V-shaped structure, which can provide relatively stable support for the steel pipe so that it will not fall during the grinding process. The two support wheels 7 on one side can also support the steel pipe and always maintain a supporting state when the steel pipe rotates. If the steel pipe needs to rotate, the servo motor needs to be started, and the servo motor drives the active sprocket to rotate, and then drives the driven sprocket to rotate together through the chain. This completes the rotation of the two rotating shafts and the driving wheel 8, the driving wheel 8 is tangent to the outer peripheral wall of the steel pipe, and when the two driving wheels 8 rotate, the steel pipe will also be driven to rotate by friction, and the grinding component is located in the middle position of the base frame 1. As long as the length of the steel pipe is greater than half of the spacing between adjacent electromagnetic adsorption components, the grinding component can grind the surface of the steel pipe through the grinding belt 16 at the opening of the cover shell 12. At the same time, the rotation direction of the grinding belt 16 is set opposite to the rotation direction of the driving roller 14 to avoid the situation where the steel pipe is further subjected to friction in the same direction and then falls off the supporting component. When the grinding assembly is grinding, the driving motor drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate through the transmission belt. Once the driven wheel rotates, it will drive the driving shaft 13 and the driving roller 14 fixedly connected thereto to rotate, and then the grinding belt 16 can also start to rotate, thereby completing the grinding of the steel pipe surface. Afterwards, by energizing the electromagnet 5 on one side, the electromagnet 5 generates a large magnetic force, which adsorbs the steel pipe, so that the steel pipe can be displaced in its length direction. In this process, other surfaces of the steel pipe can also be polished by the grinding assembly. Grind until one end of the steel pipe contacts the inner top surface of the connecting tube 4. When the steel pipe contacts the connecting tube 4, since the bearing seat 3 is made of plastic, the magnetic force of the electromagnet 5 will not burden the normal operation of the bearing seat 3. In this way, the steel pipe can still rotate smoothly. Then, the electromagnet 5 on this side is powered off through the on-off circuit connected by the brush, and the electromagnet 5 on the other side is powered on, which then adsorbs the steel pipe, causing the steel pipe to move back and forth, thereby completing the grinding of the steel pipe surface. In this process, there is no need for the operator to manually cooperate, which greatly improves the work efficiency.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
