[0002] A pipeline is a system of pipes, pipe fittings, valves, and other components used to transport gases, liquids, or fluids containing solid particles. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] Most existing pipe cutting devices move vertically downwards to cut pipes. However, when the cutting device moves downwards, it applies downward pressure to the pipe, which causes localized stress concentration and may lead to pipe bending and deformation. In addition, the pipes used in municipal engineering are mostly large in diameter, and cutting them vertically downwards will cause cutting difficulties, thereby affecting cutting efficiency and progress. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a municipal engineering pipe cutting device, which aims to improve the problem of inconvenience in cutting large-diameter pipes and the deformation of pipes due to excessive pressure during cutting.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0010] Preferably, the inner side of the roller is provided with two clamping plates, one side of the two clamping plates is fixedly connected to a lead screw, the outer side of the lead screw is sleeved with a threaded cylinder, one end of the threaded cylinder is fixedly connected to a worm gear, one side of the worm gear is meshed with a worm, and the inside of the roller is provided with a plurality of first guide rods, one end of the first guide rods being fixedly connected to the clamping plates.

[0011] Preferably, a fixing ring is fixedly connected to one side of the roller, and two clamping motors are fixedly installed on the outer surface of the fixing ring by a fixing frame, and the output end of the clamping motor is connected to the worm gear.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 , Figure 2 and Figure 4An embodiment of this utility model provides a municipal engineering pipe cutting device, including a base 1, a support block 2 fixedly connected to the top surface of the base 1, a positioning frame 3 fixedly connected to the top surface of the support block 2, a vertical plate 6 fixedly connected to the top surface of the base 1, a bearing 19 fixedly installed on the inner side of the vertical plate 6, a roller 20 installed on the inner side of the bearing 19, a rotating component provided on one side of the roller 20, two hydraulic cylinders 11 fixedly installed on the top surface of the base 1, a support 12 fixedly connected to the top of the two hydraulic cylinders 11, a cutting device 15 provided on the top of the support 12, a cutting motor 16 fixedly installed on one side of the cutting device 15 through a fixing frame, and the rotating component including a driven gear 7 and a driving gear 8, the driven gear 7 fixedly installed on one side of the roller 20, and the driving gear 8 meshing with the driven gear 7.

[0028] Specifically, the movable rotating end of the bearing 19 is connected to the roller 20, so that the roller 20 can rotate inside the bearing 19. In actual use, one end of the pipe can be passed through the inside of the roller 20. After the raceway is positioned inside the roller 20, the drive gear 8 can be rotated. The drive gear 8 drives the driven gear 7 to rotate, and the driven gear 7 can drive the roller 20 to rotate. The roller 20 can then drive the pipe positioned inside to rotate. When the rotating pipe comes into contact with the cutting device 15, the cutting device 15 can cut its outer circumference, thus ensuring that the pipe is subjected to uniform force and preventing the pipe from bending and deforming due to excessive external pressure. The top surface of the support 12 has a certain slope to support the pipe after cutting.

[0029] Reference Figure 4 A rotating motor 18 is fixedly mounted on the top surface of the base 1 by a fixing bracket, and the output end of the rotating motor 18 is connected to the drive gear 8.

[0030] Specifically, rotating the motor 18 can drive the drive gear 8 to rotate, and the rotation of the drive gear 8 can drive the driven gear 7 to rotate.

[0031] Reference Figure 3 The two sides of the positioning frame 3 are fixedly connected to the mounting frame 4. An electric push rod 24 is installed at the center of the inner side of the mounting frame 4. One end of the two electric push rods 24 is fixedly connected to the positioning plate 5. Multiple rolling columns 10 are movably installed inside the two positioning plates 5. Two second guide rods 25 are fixedly installed inside the two mounting frames 4, and one end of the second guide rod 25 is fixedly connected to the positioning plate 5.

[0032] Specifically, the telescopic end of the electric actuator 24 is connected to the positioning plate 5. Thus, by activating the electric actuator 24, the positioning plate 5 can be moved inside the positioning frame 3. In use, the pipe can be passed through the inner sides of the two positioning frames 3 in sequence. The two positioning plates 5 can clamp the two sides of the pipe, ensuring the stability of the pipe during the cutting process. Since the rolling column 10 is movably installed inside the positioning plate 5, and when the pipe rotates between the two positioning plates 5, it can drive the rolling column 10 to rotate inside the positioning plate 5, thus ensuring the stable rotation of the pipe and reducing the friction between the pipe and the positioning plate 5. The second guide rod 25 is telescopic, so when the positioning plate 5 moves, the second guide rod 25 can extend and retract accordingly, thereby increasing the stability and directionality of the positioning plate 5 during movement.

[0033] Reference Figure 4 , Figure 5 and Figure 6 The inner side of the roller 20 is provided with two clamping plates 9. A lead screw 27 is fixedly connected to one side of the two clamping plates 9. A threaded cylinder 26 is sleeved on the outer side of the lead screw 27. A worm gear 28 is fixedly connected to one end of the threaded cylinder 26. A worm 29 is meshed with one side of the worm gear 28. The inside of the roller 20 is provided with multiple first guide rods 22, and one end of the first guide rod 22 is fixedly connected to the clamping plate 9.

[0034] Specifically, the threaded cylinder 26 and the lead screw 27 are connected by a thread. When the threaded cylinder 26 is rotated to limit the lead screw 27, the lead screw 27 can be driven to extend and retract inside the threaded cylinder 26. When the lead screw 27 extends and retracts, it can drive the clamping plate 9 to move inside the roller 20. In turn, the pipe can be clamped by the movement of the clamping plate 9.

[0035] Reference Figure 2 and Figure 6 A fixing ring 21 is fixedly connected to one side of the roller 20. Two clamping motors 23 are fixedly installed on the outer surface of the fixing ring 21 through a fixing frame, and the output end of the clamping motor 23 is connected to the worm gear 29.

[0036] Specifically, by activating the clamping motor 23, the worm 29 can be rotated, which in turn drives the worm wheel 28 to rotate, and the worm wheel 28 can then drive the threaded cylinder 26 to rotate.

[0037] Reference Figure 2 and Figure 7 The top surface of the support 12 has two electric slide rails 13. A slide rail motor 14 is fixedly installed on one side of the support 12 by a fixing frame. A telescopic seat 17 is provided on the top of the electric slide rail 13. A toothed plate 30 is provided inside the telescopic seat 17. One side of the toothed plate 30 is fixedly connected to the cutting device 15. A toothed column 31 is meshed with one side of the toothed plate 30. A telescopic motor 32 is installed on the top surface of the telescopic seat 17. The output end of the telescopic motor 32 is connected to the toothed column 31.

[0038] Specifically, the electric slide rail 13 used in this device is a common existing technology. It is a device that uses an electric motor as a power source to drive the slider to operate on the slide rail. It is widely used in various industries, so it will not be described in detail here. The slider in the electric slide rail 13 is connected to the telescopic seat 17. By controlling the electric slide rail 13, the telescopic seat 17 can be moved horizontally. The telescopic seat 17 can then move the cutting device 15, thereby adjusting the position of the cutting device 15. When the pipe is fixed and the cutting position is found to be incorrect, the cutting position can be adjusted by adjusting the position of the cutting device 15. This eliminates the need to remove the pipe from the fixed state to adjust its position, thus increasing the efficiency and convenience of the cutting process. By rotating the toothed column 31, the toothed column 31 can drive the toothed plate 30 to move. The toothed plate 30 drives the cutting device 15 to move, thereby ensuring that the cutting device 15 is in contact with the surface of the pipe to complete the cutting process.

[0039] Working Principle: When using this device, place it in the designated position and pass the pipe sequentially through the two positioning frames 3 and the inside of the roller 20. Start the electric push rod 24, which moves the positioning plate 5, bringing the rolling column 10 on the surface of the positioning plate 5 into contact with the surface of the pipe. Start the clamping motor 23, which drives the worm gear 29 to rotate. The worm gear 29 drives the worm wheel 28 to rotate, which in turn drives the threaded cylinder 26 to rotate. The threaded cylinder 26 then drives the lead screw 27 to extend and retract, which in turn moves the clamping plates 9, bringing them into contact with the surface of the pipe. This positions the pipe inside the roller 20. Activating the electric slide rail 13 moves the telescopic seat 17, which in turn moves the cutting device 15, thus... The position of the cutting device 15 is adjusted to adjust the cutting distance of the pipe. The telescopic motor 32 is started, which drives the toothed column 31 to rotate. The toothed column 31 drives the toothed plate 30 to move, and the toothed plate 30 drives the cutting device 15 to move, bringing the cutting device 15 into contact with the surface of the pipe. The cutting motor 16 is then turned on, and the cutting motor 16 can cut the pipe. The rotating motor 18 is started, which drives the drive gear 8 to rotate. The drive gear 8 drives the driven gear 7 to rotate, and the driven gear 7 drives the roller 20 to rotate. The roller 20 drives the pipe clamped inside it to rotate, thereby cutting the outer surface of the pipe around its circumference. When using this device, the convenience of pipe cutting is increased, and the cutting position can also be adjusted.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
