[0002] A steel pipe grooving machine is a mechanical device used to groove or press grooves on steel pipes, and is widely used in fields such as fire protection pipes, water supply and drainage pipes, and HVAC pipes. By using rollers or cutters to roll or cut the steel pipes, the required grooves are formed. Steel pipe grooving machines of different models may have different working methods and performance characteristics to meet the processing requirements of steel pipes of different materials, specifications, and requirements.

[0003] The existing grooving machines drive the pipe to rotate and groove on its surface during processing. However, during the rotation of the pipe, due to the different lengths of the pipes, unilateral drive may cause the pipe to shift, thus affecting the grooving accuracy. Moreover, during the rotation of the pipe, since it needs to be kept stable, it may cause a shift when changing the grooving position, and it is inconvenient to reposition. Utility Model Content

[0004] The purpose of the present application is to provide a steel pipe grooving machine for construction engineering, which solves the problems mentioned in the background technique that due to the different lengths of the pipes, unilateral drive may cause the pipe to shift, thus affecting the grooving accuracy, and during the rotation of the pipe, since it needs to be kept stable, it may cause a shift when changing the grooving position, and it is inconvenient to reposition.

[0005] To achieve the above object, the present application provides the following technical solution: A steel pipe grooving machine for construction engineering, including a base, a movable plate, a support block and a support frame.

The electric push rod is started to drive the placement box to descend until the transmission belt contacts the surface of the pipeline. At this time, the No. 2 motor drives the main support wheel to rotate and makes the pipeline rotate.

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the following will further elaborate in conjunction with specific embodiments.

[0021] A steel pipe grooving machine for construction engineering, refer to Figures 1 to 3 , including a base 1, a movable plate 4, a support block 16 and a support frame 17. Two parallel guide rails 11 are fixedly connected to the top end of the base 1. The two ends of the bottom of the movable plate 4 protrude and are slidably connected inside the guide rails 11. Two auxiliary support wheels 5 are connected to the top end of the movable plate 4. A movable baffle 401 is fixedly connected to the top edge of the movable plate 4 on one side of the auxiliary support wheel 5. A fixed baffle 14 is fixedly connected to the left edge of the top end of the base 1. The fixed baffle 14 and the baffle of the movable plate 4 limit the left and right movement of the pipeline. A convex block 6 is fixedly connected to the right side wall of the movable plate 4. An electric push rod 7 is fixedly connected to the top end of the convex block 6. A connecting plate 8 is fixedly connected to the top end of the electric push rod 7. A limit box 9 is fixedly connected to the left end of the connecting plate 8. Two rollers 10 are rotatably connected to both sides of the bottom of the limit box 9, and a transmission belt 1001 is drivingly connected to the surface of the roller 10. The limit box 9 is lifted and lowered under the drive of the electric push rod 7 and contacts the pipeline. At this time, the transmission belt 1001 will fit the surface of the pipeline. During the rotation of the pipeline, the transmission belt 1001 will also rotate synchronously, which not only plays a role in upper limit but also does not affect the normal rotation of the pipeline, thus ensuring the stable placement of the pipeline and improving the grooving efficiency.

[0022] On the surface of the base 1 on the left side of the baffle, a fixing frame 12 is fixedly connected, and at the top of the fixing frame 12, two main support wheels 13 and a supporting second motor 131 are installed. An adjusting groove 15 parallel to the guide roller is provided on the side wall of the base 1. Inside the adjusting groove 15, a second threaded rod 151 is rotatably connected. A protrusion on the side wall of the support block 16 is located inside the adjusting groove 15 and is threadedly connected to the second threaded rod 151. At the top of the support block 16, a support frame 17 is fixedly connected. At the top of the support frame 17, a hydraulic cylinder 18 is fixedly connected. The bottom telescopic end of the hydraulic cylinder 18 is fixedly connected with a grooving assembly 19. When the third motor 152 is started to drive the second threaded rod 151 to rotate, the support block 16 moves horizontally, driving the support frame 17 and the grooving assembly 19 to move horizontally, enabling selection of different grooving positions for grooving without moving the position of the pipeline and repositioning, improving the convenience and practicality of the device.

[0023] Specifically, as Figure 1 shown, on the right side of the center at the top of the base 1, a chute 2 is provided. Inside the chute 2, a first threaded rod 3 is rotatably connected. A threaded block 302 is threadedly connected to the surface of the first threaded rod 3. The top of the threaded block 302 is fixedly connected to the bottom of the movable plate 4. When the threaded block 302 moves, it will drive the upper movable plate 4 to move together, thus eliminating the need for manual adjustment, which is relatively convenient.

[0024] It should be noted that, as Figure 1 shown, on the outer side wall of the base 1 at the horizontal position of the first threaded rod 3, a first motor 301 is fixedly connected. The outer end of the transmission shaft of the first motor 301 is fixedly connected to one end of the first threaded rod 3. When the first motor 301 is started, it will drive the first threaded rod 3 to rotate, thereby driving the threaded block 302 and the movable plate 4 to move.

[0025] It should be noted that, as Figure 2 shown, on the outer side wall of the base 1 at the horizontal position of the second threaded rod 151, a third motor 152 is fixedly connected. The outer end of the transmission shaft of the third motor 152 is fixedly connected to one end of the second threaded rod 151. When the third motor 152 is started, it drives the second threaded rod 151 to rotate, causing the support block 16 to drive the upper grooving assembly 19 to move horizontally.

[0026] It should be noted that, as Figure 1 and Figure 2 shown, the tops of the main support wheels 13 and the auxiliary support wheels 5 are located on the same horizontal plane, and the diameters of the main support wheels 13 and the auxiliary support wheels 5 are the same, so that the pipeline can be kept in a horizontal state when supporting the pipeline.

[0027] It should be noted that, as Figure 1 and Figure 2As shown, the movable baffle 401 and the fixed baffle 14 are both perpendicular to the surface of the base 1, so that they can fit the two ends of the pipeline. In order not to affect the normal rotation of the pipeline, the surfaces of the movable baffle 401 and the fixed baffle 14 in contact with the pipeline are very smooth, and lubricating oil is applied to further reduce the friction. Scale lines 101 are provided at the surface edge of the base 1, which can not only measure the length of the pipeline, but also assist in adjusting the position of the grooving assembly 19.

[0028] During actual use, one end of the pipeline is placed on the main support wheel 13 and abuts against the fixed baffle 14. The position of the movable plate 4 is adjusted according to the length of the pipeline, so that the other end of the pipeline is placed on the auxiliary support wheel 5 and abuts against the movable baffle 401. The electric push rod 7 is started to drive the placement box to descend until the transmission belt 1001 contacts the surface of the pipeline. At this time, the second motor 131 drives the main support wheel 13 to rotate and makes the pipeline rotate. The fixed baffle 14 and the movable plate 4 limit the left and right movement of the pipeline, while the placement box restricts the pipeline from above, so that the pipeline can remain stable during grooving and adapt to pipelines of different lengths, improving the grooving efficiency and practicability of the device; The third motor 152 is started to drive the second threaded rod 151 to rotate. During the rotation, the support block 16 moves horizontally, and then drives the support frame 17 and the grooving assembly 19 to move horizontally, and different grooving positions are selected for grooving, so that it is not necessary to move the position of the pipeline and reposition, improving the convenience and practicability of the device. During grooving, the hydraulic cylinder 18 drives the grooving assembly 19 to descend and contact the surface of the pipeline for grooving.

[0029] In addition, the components designed in the present utility model are all common standard components or components known to those skilled in the art. Their structures and principles can all be known by those skilled in the art through technical manuals or by conventional experimental methods. Those skilled in the art can fully implement them without further elaboration. The content protected by the present utility model does not involve improvements to the internal structure and method.

[0030] The embodiments disclosed in the present utility model are preferred embodiments, but are not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present utility model based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present utility model, they are all within the protection scope of the present utility model.
