Figure 1 As shown, the cutting device 100 comprises: a walking support device 1, a cutting device, a driving and rotating device 3 and a control device 4. The walking support device 1 is used to support and move the pipe; the cutting device comprises: a cutting gun 21, the cutting gun 21 is arranged downstream of the moving direction of the walking support device 1, and the cutting device is used to cut the pipe into a pipe ring; the driving and rotating device 3 is arranged upstream of the moving direction of the walking support device 1, and the driving and rotating device 3 is arranged to drive the pipe to rotate; and the control device 4 is coupled with the cutting device and the driving and rotating device 3, and is used to control the start and / or stop of the cutting device and the driving and rotating device 3.

[0029] Figure 2 FIG. 4 is a schematic diagram of a control device 4 for cutting a mining column shoe ring according to an embodiment of the present invention. Figure 2 As shown, the control device 4 includes: three switches, two contactors and a time delay relay. The switch can control the start and / or stop of the driving rotating device 3 and the cutting device; the contactor can not only connect and disconnect the circuit, but also has a low voltage release protection function, which is suitable for frequent operation and remote control, and is one of the important components in the automatic control system; the time delay relay can freely adjust the delay time according to needs. In addition, the present invention does not impose any restrictions on the number of switches, contactors, and time delay relays.

[0030] The walking support device 1 is located at the first cutting position, the control device 4 controls the driving rotation device 3 to drive the pipe placed on the walking support device 1 to rotate, and controls the cutting device to cut the pipe. After the pipe is cut, the control device 4 controls the driving rotation device 3 to stop rotating and controls the cutting device to stop cutting, and the walking support device 1 moves to the second cutting position and enters the next cutting cycle. This cycle completes the automatic cutting of the pipe.

[0031] Figure 3 FIG. 3 is a schematic diagram of a driving rotating device 3 of a mining column shoe ring cutting device according to an embodiment of the present invention. Figure 3As shown, the driving rotation device 3 includes: a driving motor 31 and a first reducer 32, a second reducer 33 and a third reducer 34. The power of the driving motor 31 is transmitted to the pipe on the third reducer 34, so that it generates a driving force and rotates at a certain speed. The first and second reducers 32 and 33 are adjustable reducers. Alternatively, the number of the reducers can also be 4, and the present invention does not impose any restrictions on the number of reducers.

[0032] In some embodiments, the cutting device 100 further includes: an adjustment device 5, which is connected to the driving rotation device 3 and is used to adjust the axis of the pipe to be consistent with the moving direction of the walking support device 1. A set of two rolling bearings that can rotate horizontally 360 degrees can be installed on the top of the walking support device 1 to stabilize the rotating pipe and adjust the pipe to prevent deviation, thereby ensuring the cutting accuracy.

[0033] Figure 4 FIG. 1 is a schematic top view of a portion 101 of a mining column shoe ring cutting device according to an embodiment of the present invention. Figure 1-2 As shown, the cutting device further includes: a guide rail 6 and / or a material trough 7, the travel support device 1 is arranged on the guide rail 6, and the arrangement direction of the guide rail 6 is consistent with the moving direction of the travel support device 1. The material trough 7 is arranged in the moving direction of the travel support device 1 and is located downstream of the cutting gun 21, and is used to hold the part of the pipe cut by the cutting gun 21. The guide rail 6 can be made of 360# I-beam.

[0034] The walking support device 1 and the planetary gear reducer together constitute components of the workstation. Four wheels are installed at the bottom of the walking support device 1 and can reciprocate on the guide rail 6 to enable the pipe to be accurately positioned and rotated smoothly.

[0035] In some embodiments, Figure 1 As shown, the cutting device includes: an air compressor 23 and a cutting machine 22. The cutting machine 22 is the main equipment for cutting pipe fittings into pipe rings. The cutting machine 22 can be a plasma cutting machine. Plasma is a gas heated to an extremely high temperature and highly ionized. It transfers arc power to the pipe fittings. The high heat causes the pipe fittings to melt and be blown away, forming a working state of plasma arc cutting. The use of a plasma cutting machine can realize automatic cutting and precise control of cutting length, and is easy to operate.

[0036] The cutting device 100 further includes: a cutting gun sliding bracket 8, on which the cutting gun 21 is arranged, and on which the cutting gun 21 is fixed and / or moved.

[0037] The air compressor 23 is connected to the cutting gun 21 and the cutting machine 22 respectively. After the compressed air of the air compressor 23 enters the cutting gun, it is distributed into two paths by the air chamber, that is, plasma gas and auxiliary gas are formed. The plasma gas melts the metal, while the auxiliary gas cools the various parts of the cutting gun 21 and blows off the melted metal.

[0038] In some embodiments, the control device 4 uses a one-button control button and a dual control mode. Turn on the air compressor 23 to pressurize, and when the pressure reaches 8Mpa, start the power supply, place the pipe on the walking support device 1, and the walking support device 1 is located at the first cutting position. According to the thickness of the pipe, set the corresponding cutting current. Place the copper nozzle of the cutting gun 21 2mm away from the pipe, press the 1-button start button, start the plasma cutting machine for cutting, delay 90ms until the pipe is cut through, and continuously start the driving rotation device 3 to drive the pipe to rotate. After the pipe rotates one circle, that is, it is cut through one circle, it automatically falls onto the material trough 7, and moves the cutting gun 21 to the second cutting position along the cutting gun sliding bracket 8 to enter the next cycle. This cycle completes the pipe cutting.

[0039] According to the embodiment of the present invention, the control device controls the driving rotating device 3 to drive the pipe placed on the walking support device 1 to rotate, and controls the cutting gun 21 of the cutting device to automatically cut the pipe. After a certain period of time, the driving rotating device 3 stops rotating and moves the cutting gun 21 to the next cutting position, and the cutting is completed in this cycle. The problems of high labor intensity, low processing efficiency and / or poor quality of manual gas cutting are solved, the damage to the workers' bodies caused by the fume generated by cutting is avoided, and the effect of reducing safety hazards is achieved.
