In addition, because the distance between the two ends of the steel pipe is far, manual grinding is generally used. The efficiency of manual processing is relatively low and the labor cost is high. Therefore, a steel pipe section grinding device is proposed to solve the above problems. Utility Model Content

[0030] Example 1:

[0031] Please combine Figures 1 to 4 As shown, the utility model provides a steel pipe cross-section grinding device including a base 1, two movable grooves 2 are provided on the base 1, and movable plates 3 are slidably connected in the two movable grooves 2. The side walls of the two movable grooves 2 are fixedly connected with hydraulic cylinders 4, and the telescopic ends of the two hydraulic cylinders 4 are respectively fixedly connected to the side walls of the two movable plates 3. Each movable plate 3 is rotatably connected with a plurality of rotating rods 5, and one end of the plurality of rotating rods 5 is connected with a grinding wheel 6 through a replacement structure. The movable plate 3 is provided with a rotating structure, and the base 1 is connected with a steel pipe placing frame 7 through the movable structure. A clamping plate 9 is slidably connected in the steel pipe placing frame 7, and a hydraulic cylinder 2 8 is fixedly connected to the upper side wall of the clamping plate 9. The hydraulic cylinder 2 8 passes through the side wall of the steel pipe placing frame 7;

[0032] When in use, the steel pipe placement frame 7 can be moved back and forth through the mobile structure, and the steel pipes can be placed on the inner wall of the steel pipe placement frame 7 in turn. Then, the clamping plate 9 can be moved up and down by starting the hydraulic cylinder 2 8, so that the steel pipe can be clamped and fixed to facilitate grinding and replacement of the steel pipe. Then, by starting the hydraulic cylinder 1 4, the telescopic end of the hydraulic cylinder 1 4 can move forward or retracted to move the mobile plate 3 left and right, so that the grinding wheels 6 at both ends are pressed against the cross-sections of the two ends of the steel pipe, and the rotating structure is started. The rotating structure drives multiple rotating rods 5 to rotate at the same time, so that multiple grinding wheels 6 can grind both ends of the steel pipe at the same time, which is more efficient than manual grinding or single-end grinding.

[0033] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, which is described below for details.

[0034] Example 2:

[0035] The replacement structure includes a mounting plate 10, which is fixedly connected to one end of the rotating rod 5. A fixing groove 16 is formed on the mounting plate 10, and a connecting plate 11 is provided in the fixing groove 16. The connecting plate 11 is fixedly connected to the side wall of the grinding wheel 6. The connecting plate 11 and the mounting plate 10 are connected by a plurality of bolts 12.

[0036] When the grinding wheel 6 is damaged and needs to be replaced, external force is applied to the bolts 12 above in sequence. After all the bolts 12 are turned out, the grinding wheel 6 is moved upward, and the connecting plate 11 is removed from the fixing groove 16, and a new grinding wheel 6 can be replaced. Similarly, when the connecting plate 11 on the new grinding wheel 6 is stuck in the fixing groove 16, the bolts 12 are turned into the connecting plate 11 in sequence, and the mounting plate 10 and the connecting plate 11 can be fixed together.

[0037] The rotating structure includes a motor plate 14, which is fixedly connected to the side wall of the movable plate 3. The motor plate 14 is L-shaped. A motor 15 is fixedly connected to the side wall of the motor plate 14. The output end of the motor 15 is fixedly connected to one end of one of the rotating rods 5. The multiple rotating rods 5 are all fixedly connected to the rotating gears 13, and the multiple rotating gears 13 are meshed in sequence.

[0038] The output end of the motor 15 rotates, thereby causing the relatively fixed rotating rod 5 to rotate, and thereby causing the rotating gear 13 fixed on the rotating rod 5 to rotate. Since multiple rotating gears 13 are engaged in sequence, when one of the rotating gears 13 rotates, the remaining rotating gears 13 will also rotate, thereby causing the remaining multiple rotating rods 5 to rotate together, and then causing the multiple grinding wheels 6 to rotate at the same time, so that both ends of the steel pipe can be ground at the same time.

[0039] The movable structure includes a second movable groove 17, which is provided on the base 1. A movable block 18 is slidably connected to the base 1. The movable block 18 is fixedly connected to the bottom side wall of the steel pipe placement frame 7. A hydraulic cylinder 3 19 is fixedly connected to the side wall of the movable block 18. The hydraulic cylinder 3 19 is fixedly connected to the base 1.

[0040] The movable groove 2 17 can adopt a multi-section hydraulic cylinder. The telescopic end of the movable groove 2 17 can be extended or retracted, and can move the movable block 18 back and forth, and then can move the steel pipe placement frame 7 fixed on the movable block 18 back and forth. The steel pipe that has been polished can be taken down and the steel pipe to be processed can be placed on it, and then moved between the two movable plates 3 for polishing.

[0041] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
