Technical Field

[0001] This utility model relates to the technical field of cutting equipment, specifically to an automatic rotary reinforced concrete pipe cutting device. Background Technology

[0002] Reinforced concrete is a composite material composed of steel bars and concrete, which is widely used in the field of construction engineering. The physical and mechanical properties of steel bars and concrete are different. Concrete has high compressive strength but low tensile strength, while steel bars have high tensile and compressive strength. In structural members, concrete mainly bears compressive force, while steel bars mainly bear tensile force. The two work together through bonding force to jointly bear the external force. In use, it is often necessary to cut according to the actual situation. Therefore, an automatic rotary reinforced concrete pipe cutting device is needed.

[0003] Existing cutting equipment uses a support mechanism to support the reinforced concrete pipe, a rotating mechanism to rotate the pipe, and a limit mechanism to cut it. However, the above-mentioned common concrete pipe cutting equipment still has shortcomings:

[0004] When cutting reinforced concrete pipes, especially when the pipe is thick, the high-speed rotating blade is prone to deformation, resulting in uneven cut surfaces and blade breakage. Utility Model Content

[0007] Preferably, the rotating assembly includes four rotating seats, with a rotating roller rotatably connected between two symmetrical rotating seats. A drive motor is fixedly installed on one side of the rotating seat where it is connected to the cutting base. The output end of the drive motor is fixedly connected to one end of one of the rotating rollers, which facilitates the self-rotation of the reinforced concrete and makes cutting easier.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-5 This utility model provides an automatic rotating reinforced concrete pipe cutting device, including a cutting base 1. A rotating component for rotating the reinforced concrete pipe is fixedly installed on one side of the top of the cutting base 1. Multiple base grooves 4 are opened below the rotating component. The multiple base grooves 4 are all opened on the cutting base 1. Auxiliary support rollers 5 are provided inside the multiple base grooves 4. A moving groove 14 is opened on the other side of the top of the cutting base 1. A cutting mechanism is slidably connected inside the moving groove 14. A monitoring mechanism for monitoring the cutting tool is fixedly installed inside the cutting mechanism. A screw groove 7 is opened on the surface of the cutting base 1. Limit components are provided at both ends of the surface of the screw groove 7.

[0023] See Figure 1 and Figure 2 Furthermore, the rotating assembly includes four rotating seats, with rotating rollers 2 rotatably connected between two symmetrical rotating seats. A drive motor 3 is fixedly installed on one side of the rotating seat where it is connected to the cutting base 1. The output end of the drive motor 3 is fixedly connected to one end of one of the rotating rollers 2. The cutting mechanism includes a movable base plate 15, the surface of which is slidably connected to the interior of a movable groove 14. A cutter 6 is fixedly installed on the top of the movable base plate 15. A telescopic hydraulic device 13 is fixedly installed on one side of the movable groove 14 where it is connected to the cutting base 1. The output end of the telescopic hydraulic device 13 is fixedly connected to one side of the movable base plate 15. The limiting assembly includes a threaded block 10, which is threadedly connected to a bidirectional lead screw 9. A limiting shaft 11 is provided on the top of the threaded block 10. A limiting roller 12 is rotatably connected to the surface of the limiting shaft 11. A limiting motor 8 is fixedly installed in the middle of one end of the cutting base 1. The output end of the limiting motor 8 is fixedly connected to one end of the bidirectional lead screw 9.

[0024] In use, the drive motor 3 is started by the control switch. The drive motor 3 rotates, driving one of the rotating rollers 2 to rotate. The reinforced concrete pipe rotates on two rotating rollers 2. The other rotating roller 2 acts as a limit assist for rotation. At this time, the reinforced concrete pipe rotates, and the auxiliary support roller 5 inside the base groove 4 rotates with the rotating roller 2, which can play an auxiliary support role. Before the reinforced concrete pipe rotates, the limit motor 8 is started to drive the bidirectional lead screw 9 to rotate. The threads on the two threaded blocks 10 correspond to the threads on the bidirectional lead screw 9. The threaded blocks 10 slide inside the screw groove 7. Therefore, the two threaded blocks 10 move the two limit rollers 12 towards the reinforced concrete pipe. When the reinforced concrete pipe rotates and is cut, it plays a limit role. When the reinforced concrete pipe rotates, the two limit rollers 12 can rotate with it and be cut by the cutter 6. When performing multi-point cutting, we can start the telescopic hydraulic device 13. The telescopic hydraulic device 13 can drive the moving base plate 15 to move, so that the cutter 6 can change the cutting point. With the help of the moving groove 14 and the moving base plate 15, the stability of the cutter 6 can be ensured during use.

[0025] See Figure 3 , Figure 4 and Figure 5Furthermore, the monitoring mechanism includes a perforated support rod 16, with a stabilizing groove 17 on the inner wall of the perforated support rod 16. A trigger rod 20 is slidably connected inside the perforated support rod 16, with a rolling steel ball 21 at one end of the trigger rod 20. A pressure sensor 19 is fixedly installed at the bottom of the inner wall of the perforated support rod 16. A stabilizing slider is fixedly connected to the surface of the trigger rod 20, and the surface of the stabilizing slider is slidably connected to the inside of the stabilizing groove 17. A return spring 18 is fixedly connected between the trigger rod 20 and the perforated support rod 16. The perforated support rod 16 is mounted on the cutter 6. A microcontroller controller 22 and an alarm light 23 are fixedly installed on the top of the cutter 6. The pressure sensor 19 and the alarm light 23 are both electrically connected to the microcontroller controller 22.

[0026] In use, the cutter 6 has a cutting blade and a blade guard. The perforated support rod 16 is installed on the blade guard, and the rolling steel ball 21 is in contact with one side of the blade. When the blade rotates to cut, the rolling steel ball 21 rotates and engages with the trigger rod 20. When the blade is deformed, the blade is not on the same plane when rotating. When the deformation is large, the blade will move the trigger rod 20 towards the pressure sensor 19 when rotating, thereby compressing the return spring 18. The trigger rod 20 contacts the pressure sensor 19. At this time, the pressure sensor 19 sends a signal to the microcontroller 22. The microcontroller 22 makes the alarm light 23 flash and cuts off the power to stop cutting.

[0027] In this embodiment, the reinforced concrete pipe is placed on two rotating rollers 2. A drive motor 3 rotates one of the rollers 2, and then a limit motor 8 is activated to restrict the position of the reinforced concrete pipe on both limit rollers 12. The cutter 6 then cuts the pipe. When the cutter encounters a thick-walled reinforced concrete pipe, the high-speed rotation of the cutter itself can easily cause overall deformation. In this case, the cutter may not rotate on a single plane, leading to an uneven cut surface and potential cutter breakage. Adding a monitoring mechanism allows for inspection without stopping the machine and removing the cutter, enabling real-time monitoring of the cutter's condition. Alarm light 23 flashes to indicate and ensure the quality of the cut. It should be noted that this utility model is an automatic rotating reinforced concrete pipe cutting device. All components are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components, which refer to power components, electrical components, and the matching monitoring computer and power supply, are connected by wires. The specific connection method should refer to the working principle above and complete the electrical connection between each electrical component in sequence. The detailed connection method is a well-known technology in this field.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
