[0002] Pipeline is a device connected by pipes, pipe fittings and valves for conveying gas, liquid or fluid with solid particles. Milling cutting is a common processing method in the production and processing of pipelines. Pipeline milling cutting refers to the process of cutting or trimming the pipeline using milling tools. This processing method can be used to make pipeline joints, cut pipeline lengths, and even make holes in the pipeline. Through milling cutting, the sealing and stability of the pipeline connection can be ensured and specific engineering requirements can be met.

[0003] In the prior art, when a pipe is milled and cut, a milling pipe cutting machine is generally used for cutting. The pipe is placed inside the milling pipe cutting machine, clamped by a fixing mechanism, and then the milling cutter is driven by a rotating mechanism to rotate around the pipe to achieve cutting.

[0023] 1. When the present invention is used, the hydraulic rod is started to push the top of the protective telescopic sleeve to move upward, and the support frame, the reinforcing ribs, the annular plate and the laser rangefinder are pushed to move. The laser rangefinder detects the distance between the detection plate and the detection data is transmitted to the PLC controller.

[0025] 3.

The waste chips in the waste chip box can be cleaned out by pulling out the baffle with force, which will not affect the next use. The protective ring can prevent the waste chips from falling onto the rotating groove and the driven wheel, affecting their normal rotation.

[0026] 4. When the present invention is used, the second forward and reverse motor is started to drive the rotating shaft and the two gears to rotate, and at the same time drive the two gear rods to move upward, lift the mounting plate upward, so that the drive motor and the milling cutter body are moved to a high place, which is convenient for cutting different positions of the pipeline and improves its flexibility.

The two auxiliary components 4 include an adjusting rod 401. The top of the two adjusting rods 401 is fixedly installed with a reinforced telescopic rod 402, and one end of the two reinforced telescopic rods 402 is fixedly installed with an arc-shaped auxiliary plate 403. The bottom ends of the two adjusting rods 401 are respectively fixedly installed on the top of the base 1 near the corner.

[0047] like Figure 2-Figure 3 and Figure 8-Figure 9 As shown, the bottom of the bottom plate 501 is installed on the bottom surface inside the base 1 by screws, the bottom of the protective telescopic sleeve 502 is installed on the top of the bottom plate 501 by bolts, the other ends of the multiple push rods 512 are all movable and penetrate into the inside of the annular plate 505, one end of the multiple springs 514 is respectively fixedly connected to the other side outer surface of the multiple top blocks 513, the other ends of the multiple springs 514 are respectively fixedly connected to one side inside the multiple embedded grooves 509, the other ends of the multiple push rods 512 are all in contact with the outer surface of the conical block 511, a connecting plate 506 is fixedly installed on the outer surface of one of the reinforcing ribs 516, a laser rangefinder 507 is fixedly installed on the bottom of the connecting plate 506, and a detection plate 50 is fixedly installed on the bottom surface of the base 1 near the bottom plate 501. 3. The spring 514 is used to elastically support the push rod 512, so that the push rod 512 can be pulled back to its original position under the elastic force of the spring 514, thereby pulling the push block 513 back to its original position. The protective telescopic sleeve 502 can protect the hydraulic rod 508 to prevent the waste chips from splashing onto the outer surface of the hydraulic rod 508 and damaging the hydraulic rod 508 when the milling cutter body 310 is cutting. The laser rangefinder 507 detects the distance between the detection plate 503 and the detection data is transmitted to the PLC controller in the form of an electrical signal. The PLC controller identifies and compares the received distance data. When the distance data meets the set threshold, the PLC controller controls the hydraulic rod 508 to pause, thereby supporting the appropriate position of the upper end of the pipeline.

[0048] The method of use and working principle of the present invention are as follows: when in use, the first forward and reverse motor 202, the second forward and reverse motor 305, the hydraulic cylinder 306, the drive motor 309, the milling cutter body 310, the laser rangefinder 507, the hydraulic rod 508 and the electric push rod 510 are all electrically connected to the external PLC controller, and the longer pipe to be cut is passed through the fixed base 201 and placed inside the base 1. At this time, the support assembly 5 is located inside the pipe, such as Figure 3As shown, multiple adjusting threaded rods 211 are then rotated in sequence so that one end of the adjusting threaded rods 211 rotates inside the clamping plate 212 and moves toward the inside of the fixed base 201. With the support of the limit shaft 213, the clamping plate 212 is pushed to move toward the pipe and contact the outer surface of the pipe. The lower end of the pipe is clamped by adjusting the cooperation between the threaded rods 211 and the clamping plate 212 so that it is fixed inside the fixed base 201. The hydraulic rod 508 and the laser rangefinder 507 are started by the external PLC controller. The top of the protective telescopic sleeve 502 is pushed upward by the hydraulic rod 508, and the structures such as the support frame 504, the reinforcing ribs 516 and the annular plate 505 are pushed upward inside the pipe, and the laser rangefinder 507 is driven to move at the same time. The laser rangefinder 507 is aligned with the detection plate 503. After the laser rangefinder 507 is started, a laser beam is emitted to the top of the detection plate 503 and the laser beam reflected back is received. The light beam is used to detect the distance between the laser rangefinder 507 and the detection plate 503. The maximum and minimum working thresholds of the distance are set in advance inside the PLC controller. As the reinforcing rib 516 moves, the laser rangefinder 507 is driven to move together. The laser rangefinder 507 detects the distance to the detection plate 503, and transmits the detection data to the PLC controller in the form of an electrical signal. The PLC controller identifies and compares the received distance data. When the distance data meets the set threshold, the PLC controller controls the hydraulic rod 508 to pause and starts the electric push rod 510. At this time, the annular plate 505 moves to the inner part of the upper part of the pipeline. Under the push of the output end of the electric push rod 510, the conical block 511 is pushed up from the support frame 504. The outer surface of the conical block 511 is set to be relatively smooth, and the end of the push rod 512 that contacts the conical block 511 is set to be arc-shaped, such as Fig. 9 As shown, when the conical block 511 moves upward, one end of the push rod 512 can slide on the outer surface of the conical block 511. The conical block 511 is narrow at the top and wide at the bottom. Fig. 9As shown, during the upward movement of the conical block 511, one end of the push rod 512 slides from the narrow part of the conical block 511 to the wider part below, thereby pushing the push rod 512 outward and pushing multiple push blocks 513 to move toward the inner wall of the pipe. At the same time, the spring 514 is pulled to become an expanded state. When the output end of the electric push rod 510 is fully pushed out, the electric push rod 510 will automatically pause. At this time, the conical block 511 pushes the push rod 512 to the maximum extent, so that multiple push blocks 513 fit tightly with the inner wall of the pipe. Under the action of the support component 5, the upper part of the pipe is supported to improve its stability and prevent the upper part of the pipe from shaking unsteadily after the milling cutting is completed by the adjustment component 3. No manual support is required by the staff, saving manpower and work. When the top block 513 fits the inner wall of the pipe, the multiple rubber nails 515 are in tight contact with the inner wall of the pipe, which improves the tightness of the top block 513 in contact with the inner wall of the pipe and improves the stability of the support. The outer surface of the hydraulic rod 508 is sleeved with a retractable protective telescopic sleeve 502, which can protect the hydraulic rod 508 and prevent waste chips from splashing onto the outer surface of the hydraulic rod 508 when the subsequent milling cutter body 310 is cutting, causing damage to the hydraulic rod 508. This solves the problem that when the milling pipe cutting machine is cutting the pipe, when the length of the inserted pipe is long, the upper end of the pipe is easy to shake and become unstable after cutting, requiring manual support from the staff, increasing the workload, consuming additional human resources, and increasing the degree of fatigue. The structure of the adjustment rod 401 is as follows Figure 2As shown, it includes an adjustment sleeve, an internal adjustment column, a fixing groove and a fastening bolt. The position of the adjustable column is adjusted by fastening the bolt. The connection between the reinforced telescopic rods 402 is relatively tight. External pulling force or thrust is required to realize the extension and retraction of the reinforced telescopic rods 402. The reinforced telescopic rods 402 are pulled outward with force to expand, thereby pushing the arc-shaped auxiliary plate 403 to move and contact with the outer surface of the pipe. Under the action of the two auxiliary components 4, the outer surface of the pipe is clamped, and the auxiliary support component 5 is used to improve the stability of the pipe and reduce shaking and instability. After the lower end of the pipe is fixed and the upper end is supported, the drive motor 309 is started, and the milling cutter body 310 is driven to rotate through the output end of the drive motor 309, and then the hydraulic cylinder 306 is started. , pushing the moving plate 308 to move, and at the same time driving the slider 311 to slide on the slide rail 312. With the cooperation of the slider 311 and the slide rail 312, the stability of the movement of the moving plate 308 can be improved. The movement of the moving plate 308 will drive the driving motor 309, the milling cutter body 310 and the waste box 313 to move toward the pipeline together, so that the milling cutter body 310 enters the inside of the pipeline from the outer surface of the pipeline. At this time, the arc surface of the waste box 313 is very close to the outer surface of the pipeline but does not contact. Then start the first forward and reverse motor 202, and the rotation of the output end of the first forward and reverse motor 202 drives the driving wheel 203 to rotate, and drives the driven wheel 205 meshing with it to rotate inside the rotating groove 204, and then drives the fixed ring 206 and the rotating plate 207 to rotate slowly. The scraper 310 is moved along the guide rail 312 to move along the guide rail 314, and the scraper 310 is moved along the guide rail 314 to move along the guide rail 314. The scraper 310 is moved along the guide rail 314 to move along the guide rail 314, and the scraper 310 is moved along the guide rail 314 to move along the guide rail 314. The second forward and reverse motor 305 is started, and the rotation of the output end of the second forward and reverse motor 305 drives the rotating shaft 315 to rotate, and drives the two gears 316 to rotate, and at the same time drives the two gear rods 303 meshing with it to move upward, and then the mounting plate 304 is lifted up, so that the drive motor 309 and the milling cutter body 310 are moved to a higher place, and the height of the milling cutter body 310 can be adjusted by the cooperation of the second forward and reverse motor 305, the rotating shaft 315, the gear 316 and the gear rod 303, so as to facilitate cutting at different positions of the pipeline and improve its flexibility.

[0049] Among them, the first forward and reverse motor 202, the second forward and reverse motor 305, the hydraulic cylinder 306, the drive motor 309, the milling cutter body 310, the laser rangefinder 507, the hydraulic rod 508 and the electric push rod 510 are all existing technologies, and their components and operating principles are all public technologies, so no excessive explanation will be given here.
