[0002] Steel pipe is a hollow steel material, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. Steel pipe can not only be used to transport fluids and powdered solids, exchange heat energy, and manufacture mechanical parts and containers, but it is also an economical steel material. During the production process, the steel pipe needs to be processed and smoothed on both ends of the steel pipe using a milling machine, and then the steel pipe is transported using a conveying device. The limit mechanism is used to limit the steel pipe on the conveying rack to prevent the steel pipe from shifting left and right during transportation, thereby increasing the stability of the steel pipe movement.

[0003] The inventors found that there are at least the following problems in the prior art that have not been solved: the existing limiting mechanism has a single function and cannot adjust the limiting mechanisms on both sides, which will result in a smaller scope of application of the equipment, thereby causing inconvenience to the subsequent movement and transportation of steel pipes of different specifications.

[0017] See also Figure 1-Figure 2The utility model provides a technical solution: a steel pipe conveying limit mechanism, comprising a base 1, two groups of limit frames 11 are arranged above the base 1, and the inner side of the limit frame 11 is rotatably connected to a guide roller 12; an adjustment mechanism: used to adjust the use angle of the guide roller 12, the adjustment mechanism includes a support rod 18 and a screw rod 2, two groups of first connecting blocks 13 are fixedly installed in the middle of the upper surface of the base 1, one end of the two groups of limit frames 11 is hinged to the two groups of first connecting blocks 13 respectively, and a second connecting block 14 is fixedly installed on the end of the limit frame 11 away from the first connecting block 13. Slide grooves 15 are horizontally symmetrically provided on both sides of the upper surface of the base 1, and a slider 16 is slidably connected to the inner side of the slide groove 15. A third connecting block 17 is fixedly installed on the upper surface of the slider 16. The two ends of the support rod 18 are hinged to the second connecting block 14 and the third connecting block 17 respectively. The screw rod 2 horizontally passes through the middle of the slider 16 and is threadedly connected to the slider 16. A servo motor 21 is fixedly connected to one side of the base 1, and the shaft end of the servo motor 21 is fixedly connected to one end of the screw rod 2. The threads on both sides of the screw rod 2 rotate in opposite directions, and the screw rod 2 is rotatably connected to the slide groove 15 through a bearing.

[0018] In this technical solution, the servo motor 21 is controlled by the corresponding controller to drive the screw 2 to rotate. The threads on both sides of the screw 2 rotate in opposite directions. During the rotation of the screw 2, the two groups of sliders 16 can be driven to move relative to or in reverse in the slide groove 15, thereby driving the two groups of third connecting blocks 17 to move relative to or in reverse. Through the combination of the support rod 18, the second connecting block 14 and the third connecting block 17, the two groups of limit frames 11 can be driven to rotate relative to or in reverse, and the angles of the guide rollers 12 inside the two groups of limit frames 11 can be further adjusted, so that steel pipes of different diameters can be limited and transmitted.

[0019] In this embodiment, a bracket 22 is fixedly installed on the side of the limit frame 11 close to the base 1, and a rubber scraper 23 is fixedly connected to the inner side of the bracket 22. The side of the rubber scraper 23 away from the bracket 22 is in contact with the outer side of the guide roller 12, and the rubber scraper 23 is in contact with the outer side of the guide roller 12.

[0020] In this technical solution, the rubber scraper 23 is in contact with the outer side of the guide roller 12 on the side away from the bracket 22. During the rotation of the guide roller 12, the impurities on the outer side of the guide roller 12 can be automatically cleaned, thereby preventing the dirt on the surface of the steel pipe from adhering to the outer side of the guide roller 12 during the process of the guide roller 12 conveying the steel pipe, thereby affecting the use effect.

[0021] In this embodiment, the guide rollers 12 are evenly distributed inside the limiting frame 11 , and the sizes of the limiting frame 11 and the guide rollers 12 match.

[0022] In this technical solution, by matching the sizes of the limit frame 11 and the guide roller 12, the guide roller 12 can provide position-limiting support for the steel pipe, thereby improving the stability of the steel pipe during transportation.

[0023] When a steel pipe conveying limit mechanism is used, the servo motor 21 is controlled by the corresponding controller to work, which can drive the screw rod 2 to rotate. The threads on both sides of the screw rod 2 rotate in opposite directions. During the rotation of the screw rod 2, the two groups of sliders 16 can be driven to move relative to or in opposite directions in the slide groove 15, thereby driving the two groups of third connecting blocks 17 to move relative to or in opposite directions. Through the combination of the support rod 18, the second connecting block 14 and the third connecting block 17, the two groups of limit frames 11 can be driven to rotate relative to or in opposite directions, and the angle of the guide rollers 12 inside the two groups of limit frames 11 can be further adjusted, so that steel pipes of different diameters can be limited and conveyed. The side of the rubber scraper 23 away from the bracket 22 is in contact with the outer side of the guide roller 12. During the rotation of the guide roller 12, the impurities on the outside of the guide roller 12 can be automatically cleaned to avoid the dirt on the surface of the steel pipe adhering to the outer side of the guide roller 12 during the process of the guide roller 12 conveying the steel pipe, thereby affecting the use effect.
