[0001] This utility model relates to the field of pipe grooving technology, specifically a grooving machine top pipe device. Background Technology

[0002] Among existing steel pipe connection methods, grooved connections are becoming increasingly common. They offer several significant advantages: firstly, they are simple to operate, requiring no special skills; ordinary workers can operate them after simple training. A single pipe connection takes only a few minutes, minimizing the technical difficulty of on-site operations, saving time, thus stabilizing project quality and improving work efficiency.

[0003] In the production of welded pipes, the end of the pipe fitting needs to be held in place by the grooving machine to ensure successful grooving. This is especially problematic during grooving tests in the production process, where operators must use a section of steel pipe to hold the fitting in place while operating the grooving machine, posing a safety hazard and increasing the workload for workers. Therefore, we propose a pipe-jacking device for the grooving machine. Utility Model Content

[0004] To address the safety hazards of existing grooving machines that require operators to hold the pipe against the machine with a steel pipe while operating it, this invention provides a pipe-jacking device for a grooving machine. This device, with its conical head, effectively prevents the pipe from slipping off the machine during grooving, thus improving its practicality. This invention solves the problems mentioned in the background section.

[0005] The technical solution of this utility model is implemented as follows: a grooving machine top pipe device includes a base, a sliding base connected to the top of the base, and columns symmetrically connected to the top of the sliding base. The tops of the two columns and the cover plate are fastened together, and a sliding bearing seat is set between the two columns. An adjusting screw is vertically set on the top of the sliding bearing seat and rotatably connected thereto. The upper end of the adjusting screw passes through the cover plate and is threaded to it. A conical shaft is rotatably connected to one side of the sliding bearing seat, and a conical head is coaxially connected to the end of the conical shaft.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1 to 3 This utility model provides a technical solution: a grooving machine top pipe device, including a base 1, a sliding base 3 connected to the top of the base 1, pressure plates 2 symmetrically connected to the top of the base 1, and the sliding base 3 slidably connected between the two pressure plates 2, as shown. Figure 2 As shown, to fix the position of the sliding base 3 after sliding adjustment, the sliding base 3 is connected to the base 1 through the locking screw 11. Several first screw holes 18 are opened on the top of the base 1, and a through hole 22 is opened on the sliding base 3. The locking screw 11 passes through the through hole 22 and connects to the first screw hole 18. After the bottom of the locking screw 11 is turned out from the first screw hole 18, the sliding base 3 is pushed, so that the position of the sliding base 3 can be quickly adjusted. After the adjustment is completed, the sliding base 3 can be stably connected by rotating the locking screw 11. The structure is simple and easy to operate, and can meet the needs of pipe fittings of different lengths.

[0022] like Figure 1 As shown, symmetrical columns 4 are connected to the top of the sliding base 3, and the tops of the two columns 4 and the cover plate 8 are fastened together. A sliding bearing seat 6 is set between the two columns 4. An adjusting screw 9 is vertically connected to the top of the sliding bearing seat 6 and rotates thereto. A screw connector 7 is rotatably connected to the top of the sliding bearing seat 6, and the bottom of the adjusting screw 9 is connected to the screw connector 7. At the same time, the upper end of the adjusting screw 9 passes through the cover plate 8 and is threaded to it. A second screw hole 20 is provided on the cover plate 8, and the adjusting screw 9 and the second screw hole 20 are threaded together. When the adjusting screw 9 is rotated, the sliding bearing seat 6 can be moved up and down between the two columns 4. In order to facilitate the user to rotate the adjusting screw 9 quickly, a crossbar 13 is fixedly connected to the top of the adjusting screw 9. Rotating the crossbar 13 can easily adjust the adjusting screw 9 by sliding, thereby adjusting the center height of the sliding bearing seat 6 to meet the needs of different pipe fittings for groove pressing.

[0023] like Figure 1 , 3As shown, in order to achieve position limiting at the end of the pipe fitting, a conical shaft 12 is rotatably connected to one side of the sliding bearing seat 6. The conical shaft 12 is connected to the sliding bearing seat 6 through a rolling bearing 17, and a conical head 10 is coaxially connected to the end of the conical shaft 12. In actual use, a threaded connection hole is opened on the conical head 10, and the conical head 10 and the conical shaft 12 are connected together by threads, which facilitates the use, installation and replacement of the conical head 10. The size of the conical head 10 can be changed according to the specifications of the grooved pipe, so that one set of equipment can meet the needs of grooving multiple specifications of welded pipes.

[0024] like Figure 2 , 3 As shown, to ensure the stable placement of the sliding bearing seat 6, sliders 14 are symmetrically connected to both sides of the sliding bearing seat 6. Slide grooves 5 are provided on the adjacent sides of the two columns 4, allowing the sliders 14 to be slidably connected within the slide grooves 5. A through groove 19 is provided on one side of the slide groove 5, and a guide screw 16 is connected to the side wall of the slider 14, passing through the through groove 19. When the sliding bearing seat 6 is adjusted up and down, the guide screw 16 slides within the through groove 19, effectively providing guidance. The end of the guide screw 16 is threaded with a connecting pipe 21. One end of the connecting pipe 21 abuts against the outer wall of the column 4, and the other end of the connecting pipe 21 is coaxially connected with a handle 15. By rotating the handle 15, the connecting pipe 21 can slide on the guide screw 16, so that the end of the connecting pipe 21 abuts against the outer wall of the column 4. This effectively improves the stability of the sliding bearing seat 6 placed between the two columns 4, ensures the stable placement of the cone head 10, and thus provides stable positioning of the end of the pipe fitting.

[0025] In summary, when using this grooving machine pipe-jacking device, it will be used in conjunction with the grooving machine. Rotating the adjusting screw 9 will cause the cone head 10 to slide up and down, so that it is placed coaxially with the pipe to be processed. During grooving, the cone head 10 is used to hold the pipe to be processed to prevent it from sliding off the grooving machine. Since the height of the cone head 10 can be freely adjusted, and the size of the cone head 10 can be replaced according to the specifications of the grooving pipe, the operation is simple, the work efficiency is high, and the practicality of the device is greatly improved.
