[0028] A device for beveling and grinding subsea pipelines, such as Figures 1-3 As shown, the system includes a circular grinding ring seat 18, with a circular slide rail 6 on one side of the grinding ring seat 18; two sets of slide blocks 7 are symmetrically mounted on the circular slide rail 6, and columns 19 are mounted on the two sets of slide blocks 7. Each set of columns 19 has an adjusting groove 20. A steering slider 8, which is adapted to the cross-sectional dimensions of the circular slide rail 6 and is slidably engaged, is mounted on the bottom of the slide block 7; a crossbar 10 parallel to the grinding ring seat 18 is installed between the two sets of columns 19, and a guide rail 21 is provided on the crossbar 10. Guide blocks 9, which are adapted to the cross-sectional dimensions of the adjusting groove 20 and are slidably engaged, are mounted at both ends of the crossbar 10; two sets of synchronously operating servo motors 11 are symmetrically mounted in the middle of the guide rail 21; the output shaft of each set of servo motors 11 is coaxially connected to a lead screw 12; each set of lead screws 12 is threadedly connected to a linear slider 13, which is adapted to the cross-sectional dimensions of the guide rail 21 and is slidably engaged; and a limit switch is mounted on each set of linear sliders 13. The limiting mounting base 14 is equipped with a grinding rod 15 for grinding the bevel of the subsea pipeline. Through the setting of a circular grinding ring seat 18 and an annular slide rail 6 on one side, and the two sets of slide seats 7 symmetrically installed on the annular slide rail 6 and the steering slider 8 at the bottom of the slide seats 7, the slide seats 7 can be rotated in a circle on the annular slide rail 6. The column 19 on the slide seat 7 and the adjusting slide groove 20 on the column 19 cooperate with the guide blocks 9 at both ends of the crossbar 10 to facilitate the adjustment of the position of the crossbar 10 between the columns 19. The guide slide 21, servo motor 11, lead screw 12 and linear slider 13 on the crossbar 10 can make the linear slider 13 slide in the guide slide 21 through the lead screw drive. The grinding rod 15 installed on the upper limit mounting base 14 of the linear slider 13 can grind the bevel of the subsea pipeline at a suitable position. The overall structure makes the device able to flexibly adjust the grinding position, improve the grinding accuracy and efficiency.

[0029] Furthermore, the grinding ring seat 18 has symmetrical mounting seats 1 at both ends on the side away from the annular slide rail 6. The mounting seats 1 are equipped with clamping mechanisms for fixing the subsea pipeline. The clamping mechanisms include two sets of symmetrically arranged fixing clamping rings 5, positioning blocks 16, threaded rods 4 on the upper and lower sides of the mounting seats 1, and several sets of guide rods 2. Each set of fixing clamping rings 5 ​​has symmetrically arranged sliding plates 3 at both ends. The sliding plates 3 are threadedly connected to the threaded rods 4, so that the position of the fixing clamping rings 5 ​​can be adjusted by rotating the threaded rods 4 to drive the sliding plates 3 to move, thereby achieving a firm clamping and fixing of the subsea pipeline and ensuring the stability of the pipeline during the grinding process.

[0030] Among them, the cross-sections of the annular slide rail 6, the steering slider 8, the guide slide 21, and the linear slider 13 are all convex, which makes the sliding fit between the steering slider 8 and the annular slide rail 6, and between the linear slider 13 and the guide slide 21 more stable, preventing the components from disengaging during the sliding process and improving the overall operational reliability of the device.

[0031] Specifically, each set of slide plates 3 is equipped with four sets of guide rods 2. The guide rods 2 are located between the positioning block 16 and the mounting base 1. The slide plate 3 and the guide rods 2 slide together. The guide rods 2 guide the slide plate 3, ensuring that the slide plate 3 maintains linear motion during movement, improving the accuracy and stability of the movement of the fixed clamping ring 5, and thus improving the precision of clamping the subsea pipeline.

[0032] In addition, the threaded rod 4 is threadedly connected to the positioning block 16, and the threaded rod 4 is rotatably connected to the mounting base 1 via a bearing. Furthermore, an adjusting turntable 17 is coaxially mounted on the end of the threaded rod 4 away from the mounting base 1, which allows the operator to easily drive the threaded rod 4 to rotate by rotating the adjusting turntable 17, thereby adjusting the position of the fixed clamping ring 5, making the operation more convenient and labor-saving.

[0033] The working principle of this utility model's subsea pipeline beveling and grinding device:

[0034] 1. Pipeline fixing: Place the submarine pipeline in the grinding ring seat 18, and rotate the adjusting turntable 17 at the end of the threaded rod 4 on the upper and lower sides of the mounting seat 1; when the threaded rod 4 rotates, the sliding plate 3 connected to it moves under the guidance of the guide rod 2, which drives the fixing clamping ring 5 to move closer, and firmly clamps the submarine pipeline between the positioning blocks 16 to ensure that the pipeline will not shake during the grinding process.

[0035] 2. Preliminary Position Adjustment: Based on the approximate position of the pipe bevel, move the slide block 7 along the annular slide rail 6. The steering slider 8 at the bottom of the slide block 7 cooperates with the annular slide rail 6 to achieve smooth sliding of the slide block 7 and adjust the circumferential position of the grinding ring seat 18. At the same time, the guide blocks 9 at both ends of the crossbar 10 slide in the adjusting groove 20 of the column 19 to adjust the position of the crossbar 10 between the columns 19, so that the grinding rod 15 initially approaches the grinding area.

[0036] 3. Precise grinding and positioning: Start the servo motor 11 in the guide slide 21 on the crossbar 10. The servo motor 11 drives the lead screw 12 to rotate. The linear slider 13, which is threaded to the lead screw 12, slides in the guide slide 21. The grinding rod 15 installed on the upper limit mounting seat 14 of the linear slider 13 moves accordingly and is precisely adjusted to the grinding position of the bevel of the subsea pipeline.

[0037] 4. Grinding operation: The grinding rod 15 is driven by a motor or electric motor (not marked in the figure) to grind the bevel of the subsea pipeline. During the grinding process, the position of the above components can be finely adjusted according to the actual situation to ensure the grinding quality.
