[0002] Pipe fittings in the oil field need to have high strength, pressure resistance, corrosion resistance, and high temperature resistance. In the oil industry, it is necessary to lay long pipelines to transport oil. Since oil needs to be laid in a relatively harsh environment, when the pipeline leaks or breaks and cannot be repaired by welding, a new pipe section needs to be replaced. During the replacement process, the pipe diameter needs to be marked to facilitate cutting.

[0003] During the replacement process, the pipe diameter needs to be marked for easy cutting. The existing marking tools use marking strips, which are bundled on the pipeline, and then the marking tools are used to draw lines according to the marking strips. When the marking strips are bundled, it is easy for the marking strips to be not perpendicular to the central axis of the pipeline, resulting in uneven pipeline cutting. Therefore, a petroleum pipeline cutting marking device is proposed. Utility Model Content

[0029] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0030] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is usually placed when in use.

[0031] like Figures 1 to 5A petroleum pipeline cutting marking device includes: a fixed block 1, a rotating groove 103 is provided on the outer side of the fixed block 1; an identification member 2 is arranged on the outer side of the fixed block 1 and is used to mark the cutting position; a clamping component 3 is arranged inside the fixed block 1 and is used to adjust the position of the fixed block 1; a limiting component 4 is arranged on the outer side of the clamping component 3 and is used to control the angle of the clamping component 3. Specifically, when it is necessary to mark the cutting part of the pipeline, the clamping component 3 is first controlled by the limiting component 4 to clamp the pipeline. In the process of clamping the pipeline by the clamping component 3, the length direction of the fixed block 1 is perpendicular to the axis line of the pipeline through the cooperation of the clamping component 3 and the fixed block 1, so as to ensure the accuracy of the position during the marking process, and then the part to be cut is marked by the identification member 2, so as to facilitate the marking operation of the staff.

[0032] like Figures 1 to 5 A fixing piece 102 is also provided on the outside of the fixing block 1. The fixing piece 102 is C-shaped. A guide groove 104 is provided inside the fixing piece 102, and the guide groove 104 runs through one side of the fixing piece 102. Specifically, the bottom of the fixing block 1 is in an arc shape, thereby reducing the contact area between the fixing block 1 and the pipeline, avoiding excessive contact area between the fixing block 1 and the pipeline, which causes inconvenience in adjustment.

[0033] like Figures 1 to 5 The clamping assembly 3 includes an arc clamp 301 and a first gear 303. The first gear 303 is arranged inside the rotating groove 103, and the first gear 303 is multiple. The arc clamp 301 is arranged on the outside of the first gear 303, and the arc clamp 301 is in an arc shape. A gear set 5 for power transmission is also provided between the first gears 303. Specifically, the arc clamp 301 is arranged at both ends of the fixed block 1. Since the arc clamp 301 and the fixed block 1 both have a certain width, the arc clamp 301 and the fixed block 1 are automatically adjusted in the process of fitting with the pipeline, ensuring that the length direction of the fixed block 1 is perpendicular to the axis of the pipeline. When in use, the pipeline to be cut is placed between the arc clamps 301, and then the arc clamps 301 are rotated in opposite directions to clamp the pipeline, so that the outer side of the pipeline is respectively in contact with the arc clamps 301 on both sides and the fixed block 1 on the top, thereby adjusting the angle between the length direction of the fixed block 1 and the axis while fixing the position of the fixed block 1, so as to avoid the skewed cutting mark causing the pipeline incision to be skewed.

[0034] like Figures 1 to 5A baffle 302 is provided on the outside of the arc clamp 301. There are multiple baffles 302, and the shape of the baffle 302 is the same as that of the arc clamp 301. Specifically, the baffle 302 is flush with the inner side of the arc clamp 301 to avoid the presence of steps between the baffle 302 and the inner side of the arc clamp 301, which causes the position of the fixed block 1 to be tilted. When in use, the baffle 302 increases the contact length of the arc clamp 301 with the pipeline, so that the angle of the fixed block 1 is adjusted by the cooperation of the arc clamp 301 and the baffle 302, ensuring the accuracy of the angle between the length direction of the fixed block 1 and the axis centerline of the pipeline during use.

[0035] like Figures 1 to 5 The gear set 5 includes a second gear 502, and there are multiple second gears 502. The multiple second gears 502 are meshed with each other, and the first gear 303 is meshed with the second gear 502. The second gears 502 are arranged in an even number. A fixing rod 501 is provided on the outer side of the second gear 502 on one side, and one end of the fixing rod 501 passes through, and the axis of the fixing rod 501 coincides with the center of the fixing member 102. Specifically, the multiple second gears 502 are connected to the first gears 303 on both sides, so that the arc clamp 301 can rotate synchronously, ensuring that during the process of clamping the pipeline, the pipeline is located in the middle of the fixing block 1 and the arc clamp 301, so that the position of the pipeline is accurate during clamping.

[0036] like Figures 1 to 5 The limiting assembly 4 includes a connecting rod 401, a limiting rod 402 and a fixing sleeve 405. One end of the connecting rod 401 is connected to the fixing rod 501. The limiting rod 402 is arranged at the other end of the connecting rod 401. The limiting rod 402 slides inside the guide groove 104. The fixing sleeve 405 is arranged on the outside of the limiting rod 402. A spring 404 is sleeved on the outside of the limiting rod 402, and the two ends of the spring 404 are respectively connected to the fixing sleeve 405 and the connecting rod 401. The limiting rod 402 is provided with a friction pad 403 relative to the end of the guide groove 104. Specifically, the length of the connecting rod 401 is equal to the radius of the fixing member 102. When the angle of the arc clamp 301 needs to be adjusted When the fixing sleeve 405 is in operation, the limiting rod 402 is first pulled by the fixing sleeve 405 to move relative to the fixing piece 102. During the movement of the limiting rod 402, the friction pad 403 is separated from the guide groove 104, thereby releasing the limiting of the fixing rod 501. After the adjustment of the arc clamp 301 is completed, the fixing sleeve 405 is loosened, so that the fixing sleeve 405 drives the limiting rod 402 and the friction pad 403 to move relative to the fixing piece 102 under the pull of the spring 404, so that the moving limiting rod 402 pushes the friction pad 403 to contact the guide groove 104, thereby limiting the fixing rod 501 again, ensuring the stability of the angle of the arc clamp 301 during the process of clamping the pipe.

[0037] like Figures 1 to 5The identification member 2 includes a connecting block 202, a storage roller 203 and a winding belt 201. The connecting block 202 is arranged on one side of the fixed block 1. A storage roller 203 is arranged inside the connecting block 202. The winding belt 201 is wound around the outside of the storage roller 203. Specifically, one end of the winding belt 201 is connected to the storage roller 203, and the other end of the storage roller 203 is provided with a connecting piece, which is connected to the outside of the connecting block 202, so that when marking the pipeline, the winding belt 201 can be wound around the pipeline, and at the same time, the winding belt 201 is fixed by the cooperation of the connecting piece and the connecting block 202 to ensure the stability of the position of the winding belt 201 during marking.
