[0028] The present disclosure will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0029] Refer to Figures 1-3 , a rotating device 100 for flame cutting of steel pipes, used to drive the rotation of the steel pipe 116, including: a base 101, a fixed plate 102, a driving roller 103, a motor 104, a first adjusting plate 105, a second adjusting plate 106, a driven roller 107, a handwheel 111, a first adjusting component for adjusting the position of the first adjusting plate 105, a second adjusting component for adjusting the position of the second adjusting plate 106, and a transmission component for driving the second adjusting component.

[0030] The fixing plate 102 is fixedly connected to the base 101. There are two fixing plates 102, which are respectively located at both ends of the driving roller 103. The driving roller 103 is rotatably connected to the fixing plate 102. The motor 104 is fixedly connected to the fixing plate 102, and the output shaft of the motor 104 is fixed to the driving roller 103. Both ends of the driven roller 107 are respectively rotatably connected to the first adjusting plate 105 and the second adjusting plate 106. The handwheel 111 is fixedly connected to the first lead screw 108. The base 101 is provided with a first clearance groove 101c for the driving roller 103 and the driven roller 107 to rotate, and is arranged with a gap from the driving roller 103 and the driven roller 107.

[0031] The first adjusting assembly is used to adjust the position of the first adjusting plate 105, and includes: a first lead screw 108 and a first slider 109. The first lead screw 108 is rotatably connected to the base 101. The first slider 109 is horizontally slidably connected to the base 101, and its interior is threadedly connected to the first lead screw 108. Specifically, the base 101 is provided with a first sliding groove 101a extending along the length direction of the base 101, and the first slider 109 moves along the first sliding groove 101a. The first adjusting plate 105 is fixedly connected to the first slider 109.

[0032] The second adjusting assembly is used to adjust the position of the second adjusting plate 106, and includes: a second lead screw 110 and a second slider 112. The second lead screw 110 is rotatably connected to the base 101. The second slider 112 is horizontally slidably connected to the base 101, and its interior is threadedly connected to the second lead screw 110. Specifically, the base 101 is provided with a second sliding groove 101b extending along the length direction of the base 101, and the second slider 112 moves along the second sliding groove 101b. The second adjusting plate 106 is fixedly connected to the second slider 112. The first adjusting plate 105 is located at the upper end of the first slider 109, and the second adjusting plate 106 is located at the upper end of the second slider 112.

[0033] The transmission assembly is used for the transmission of the second lead screw 110 and includes: a first synchronous pulley 113, a second synchronous pulley 114, and a synchronous belt 115. The first synchronous pulley 113 is fixedly connected to the first lead screw 108. The second synchronous pulley 114 is fixedly connected to the second lead screw 110. Both ends of the synchronous belt 115 are sleeved on the first synchronous pulley 113 and the second synchronous pulley 114 respectively. Rotate the handwheel 111, the rotation of the handwheel 111 drives the rotation of the first lead screw 108, and the first slider 109 moves along the first chute 101a. Therefore, the rotation of the first lead screw 108 will drive the movement of the first slider 109, thereby adjusting the position of the first adjusting plate 105. At the same time, the rotation of the first lead screw 108 drives the rotation of the first synchronous pulley 113, and the rotation of the first synchronous pulley 113 drives the rotation of the second synchronous pulley 114 through the synchronous belt 115, thereby driving the rotation of the second lead screw 110. The second slider 112 moves along the second chute 101b. The second slider 112 is threadedly connected to the second lead screw 110. Therefore, the second lead screw 110 will drive the second slider 112 to move along the second chute 101b, thereby adjusting the position of the second adjusting plate 106. Therefore, the positions of the first adjusting plate 105 and the second adjusting plate 106 can be adjusted simultaneously, thereby adjusting the position of the driven roller 107, which is applicable to steel pipes 116 of different diameters.

[0034] Workflow: The motor 104 drives the driving roller 103 to rotate. The rotation of the driving roller 103 drives the relative rotation of the steel pipe 116. The rotation of the steel pipe 116 will cause the relative rotation of the driven roller 107 and the steel pipe 116 (that is, the driven roller 107 rotates in the same direction as the driving roller 103). Then, the flame cutting machine will cut the rotating steel pipe 116. Therefore, it is more convenient for the flame cutting machine to cut the pipe. At the same time, when it is necessary to cut steel pipes 116 of different diameters, rotate the handwheel 111. The rotation of the handwheel 111 drives the rotation of the first lead screw 108, and the first slider 109 moves along the first chute 101a. Therefore, the rotation of the first lead screw 108 will drive the movement of the first slider 109, thereby adjusting the position of the first adjusting plate 105.

[0035] At the same time, the rotation of the first lead screw 108 drives the rotation of the first synchronous pulley 113, and the rotation of the first synchronous pulley 113 drives the rotation of the second synchronous pulley 114 through the synchronous belt 115, thereby driving the rotation of the second lead screw 110. The second slider 112 moves along the second chute 101b. The second slider 112 is threadedly connected to the second lead screw 110. Therefore, the second lead screw 110 will drive the second slider 112 to move along the second chute 101b, thereby adjusting the position of the second adjusting plate 106. Therefore, the positions of the first adjusting plate 105 and the second adjusting plate 106 can be adjusted simultaneously, thereby adjusting the position of the driven roller 107, which is applicable to steel pipes 116 of different diameters.
