[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1, reference Figures 1 to 5 The active traction equipment for the production of thermal insulation pipes includes a platform 1, which is rotatably connected to multiple groups of first rollers 2 through bearings. The first rollers 2 can rotate at the platform 1. One end and the other end of the platform 1 are rotatably connected to double-headed screws 3 through bearings. Two groups of double-headed screws 3 are fixedly connected with groove wheels 4. The two groups of groove wheels 4 are rotatably connected through belts 5. The two groups of double-headed screws 3 can be rotated synchronously by the transmission of the two groups of groove wheels 4 and the belts 5. Two groups of vertical plates are threadedly connected to the two groups of double-headed screws 3. 6. Two groups of double-headed screws 3 can drive two groups of vertical plates 6 to adjust the spacing. The two groups of vertical plates 6 are rotatably connected to multiple groups of second rollers 7 through bearings. By adjusting the spacing between the two groups of vertical plates 6, the space between the two rows of second rollers 7 and the multiple groups of first rollers 2 can be changed, so that insulation pipes of different calibers can be placed between the two rows of second rollers 7 and the multiple groups of first rollers 2, so that the insulation pipes of different calibers can be pulled and moved straightly horizontally between the two rows of second rollers 7 and the multiple groups of first rollers 2.

[0024] In this embodiment, hydraulic cylinders 8 are installed at the four corners of the bottom end of the platform 1, and bases 9 are installed at the bottom ends of multiple groups of hydraulic cylinders 8. The hydraulic cylinders 8 can drive the platform 1 to move up and down. Multiple groups of wheel bodies 10 are installed at the bottom end of the platform 1. When the platform 1 moves down, the hydraulic cylinders 8 can make the wheel bodies 10 contact with the external ground, and the whole can move. Multiple groups of motors 11 are installed on the platform 1. The model of the motor 11 is selected according to actual work requirements. The output ends of the multiple groups of motors 11 are connected to the corresponding first roller bodies 2. The outer walls of the multiple groups of first roller bodies 2 and the second roller bodies 7 are fixedly connected with rubber sleeves 12. The rubber sleeves 12 are used to increase the traction stability of the second roller body 7 and the first roller body 2 on the insulation pipe. Handles 13 are fixedly connected to the two groups of double-headed screws 3. A rubber pad 14 is fixedly connected to the bottom end of the base 9. The base 9 is processed with a hollow area so that the wheel body 10 can pass through the base 9 and contact the external ground.

[0025] The working principle of this embodiment is as follows: when in use, first, according to the actual aperture of the thermal insulation pipe, the handle 13 is coordinated with the transmission of the two sets of groove wheels 4 and the belt 5, and the two sets of double-headed screws 3 are rotated synchronously. The two sets of double-headed screws 3 can adjust the spacing between the two sets of vertical plates 6, so that the space between the two rows of second rollers 7 and the multiple sets of first rollers 2 can be changed, and can be changed to a space suitable for the aperture of the thermal insulation pipe. After the change, the multiple sets of motors 11 are connected to an external power supply and a driving device, and the thermal insulation pipe is placed at one end of the multiple sets of first rollers 2 and second rollers 7. Some of the first rollers 2 are active, and the remaining first rollers 2 and second rollers 7 are driven. The thermal insulation pipe can be pulled straight horizontally until the thermal insulation pipe is moved out at the other end, and the pulling operation of the thermal insulation pipe can be completed. When it is necessary to move the whole, the multiple sets of hydraulic cylinders 8 are connected to the external driving device, and the multiple sets of hydraulic cylinders 8 can move the platform 1 downward, so that the wheel body 10 can contact the external ground, and the whole can be moved using the wheel body 10.
