The driving wheels 4-4 are connected to the output end of the motor 4-3. The lifting frame 4-1 is provided with a screw thread. A circular hole 4-5 is provided on the surface, a mounting frame 4-6 is fixedly connected to the surface of the lifting frame 4-1, a spray gun 4-7 is arranged in the mounting frame 4-6, the spray gun 4-7 is connected to the gas tank 3, a pair of side frames 4-8 are arranged at both ends of the lifting frame 4-1, a pressure rod 4-9 is rotatably connected to the side frame 4-8 through a pin shaft, a pulley 4-10 is arranged at one end of the pressure rod 4-9, a groove 4-11 is provided on the outer surface of the pressure rod 4-9, and a first spring 4-12 is connected between the groove 4-11 and the side frame 4-8.

[0030] In this embodiment, in order to achieve the effect of driving the steel pipe to rotate for gas cutting, a rotary gas cutting assembly 4 is designed. A lifting frame 4-1 is vertically slidably connected in the fixed frame 2, and a screw screw 4-2 is internally rotatably connected and connected to the lifting frame 4-1 through a threaded connection, which is used to control the height adjustment of the lifting frame 4-1. Drive wheels 4-4 are provided at both ends of the lifting frame 4-1 and motors 4-3 are installed. The motor 4-3 can drive the drive wheel 4-4 to rotate. The drive wheel 4-4 is used to drive the steel pipe.

A pulley 4-10 is provided at one end of the pressure rod 4-9 for supporting on both sides of the contact point of the driving wheel 4-4, and a groove 4-11 is provided on the outer surface of the pressure rod 4-9, and a first spring 4-12 is connected inside. The upper end of the first spring 4-12 is connected to the side frame 4-8, and the pulley 4-10 is pressed tightly against the surface of the steel pipe through the elastic force of the first spring 4-12, thereby improving the stability of the steel pipe rotation.

[0031] Furthermore, the supporting assembly 5 includes a rectangular seat 5-1, which is fixed on the surface of the base 1. A pair of rectangular grooves 5-2 are provided on the surface of the rectangular seat 5-1. A pair of round rods 5-3 are provided in the rectangular grooves 5-2.

[0035] Furthermore, the surface of the driving wheel 4-4 is a raised anti-slip structure surface.

[0036] In this embodiment, the driving wheel 4 - 4 has a raised anti-skid structure surface, so that when the driving wheel 4 - 4 rotates, it can drive the steel pipe to rotate smoothly.

[0037] Furthermore, the pressure rod 4-9 can be rotated upward by 60° through the pin connection.

[0038] In this embodiment, by rotating upward at an angle of 60°, the driving wheel 4-4 and the pulley 4-10 can contact the surface of the steel pipe at the same time.

[0039] When it is needed, place the steel pipe on the mobile frame 5-4, adjust the processing position, turn the screw 4-2, control the lifting frame 4-1 to move the rod downward, the pulley 4-10 at the lower end of the pressure rod 4-9 first contacts the surface of the steel pipe, and then continues to descend, the pressure rod 4-9 rotates in coordination and maintains a certain pressure through the elastic force of the first spring 4-12, and the bottom mobile frame 5-4 cooperates to move to both sides, and stops when the driving wheel 4-4, the first rotating rod 5-6 and the second rotating rod 5-7 all contact the surface of the steel pipe, and then turn on the spray gun 4-7 for gas cutting, and start the motor 4-3 at the same time, drive the driving wheel 4-4 to rotate to drive the steel pipe to rotate slowly, and the steel pipe will not fall off after disconnection, and can be removed manually.
