DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] The present invention will be described in detail below with reference to the accompanying drawings.
[0019] Example 1:
[0020] The following is combined with Figure 1-4This embodiment describes an insulation pipe cutting device, comprising: an annular gas hood 1, the annular gas hood 1 being connected to an air inlet pipe 2, the air inlet pipe 2 being connected to a combustible gas tank and an oxygen tank via an air pipe and a regulating valve, the inner ring of the annular gas hood 1 being rotatably connected to a sealing swivel 3, the sealing swivel 3 being connected to a nozzle 4, the nozzle 4 being connected to the interior of the annular gas hood 1, the outer surface of the sealing swivel 3 being connected to a gear ring 5, the gear ring 5 being meshed with a gear 6, the gear 6 being connected to an input shaft 7, the input shaft 7 being rotatably connected to a frame 8, a conveying mechanism 9 being capable of conveying the insulation pipe into the sealing swivel 3, the axes of the insulation pipe and the sealing swivel 3 coinciding;
[0021] The insulation pipe is coaxially conveyed into the sealing swivel 3 through the conveying mechanism 9, and the gas from the combustible gas tank and the oxygen tank enters the annular gas cover 1 through the air pipe and the regulating valve, is mixed and sprayed out by the nozzle 4 and ignited, and the input shaft 7 is turned on to drive the gear 6 to rotate, the gear 6 drives the gear ring 5 to rotate, the gear ring 5 drives the sealing swivel 3 to rotate, the sealing swivel 3 drives the nozzle 4 to rotate, and the nozzle 4 drives the flame to rotate to cut the coaxial insulation pipe to complete the circular cutting. When cutting vertically, the conveying mechanism 9 can be controlled to convey the insulation pipe.
[0022] The conveying mechanism 9 includes an articulated frame 91. The two articulated frames 91 are mirror-imaged relative to the vertical center plane of the sealing swivel 3. The lower parts of the two articulated frames 91 are staggered and rotatably connected to the rotating shaft 92. The rotating shaft 92 is rotatably connected to the frame 8. The axis end of the roller 93 is rotatably connected inside the articulated frame 91. The axis end of the roller 93 is connected to the power. The outer end side surfaces of the two articulated frames 91 are respectively connected to slide rails 94. The slide rails 94 are slidably connected to cylindrical slides 95. The cylindrical slides 95 are connected to the telescopic ends of the hydraulic cylinders 96. The two hydraulic cylinders 96 are mirror-imaged relative to the vertical center plane of the sealing swivel 3. The fixed ends of the two hydraulic cylinders 96 are both connected to the frame 8.
[0023] Place the insulation pipe between the two sets of rollers 93, turn on the power of the rollers 93 to transport the insulation pipe. At this time, the axis of the insulation pipe is located on the vertical center plane of the sealing swivel 3. By controlling the simultaneous extension and retraction of the two hydraulic cylinders 96, the extension end of the hydraulic cylinder 96 drives the cylindrical slide 95 to slide in the slide rail 94. The two slide rails 94 drive the two articulated frames 91 to open and close synchronously. The two articulated frames 91 drive the axis of the insulation pipe to rise and fall vertically along the vertical center plane of the sealing swivel 3 through the rollers 93 until the axis of the insulation pipe coincides with the axis of the sealing swivel 3, and the ring cutting begins.
[0024] The lower end of one side shaft 92 is connected to a bevel gear 1 97, which is meshed with a bevel gear 2 98, which is connected to the shaft 92;
[0025] When the articulated frame 91 opens and closes, the articulated frame 91 drives the bevel gear 1 97 to roll on the surface of the bevel gear 2 98 through the roller 93. The connection between the bevel gear 1 97 and the bevel gear 2 98 will not be disconnected. The rotating shaft 92 drives the bevel gear 1 97 to rotate through the bevel gear 2 98, and the bevel gear 1 97 drives the roller 93 to rotate to complete the transmission. Only one side of the roller 93 is connected to the power, which meets the conveying requirements and leaves sufficient movement space for the bevel gear 1 97 without interference.
