[0030] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0031] As Figure 1 shown, a multi-layer composite heat preservation steel pipe, the:

[0032] includes a heat preservation pipe 10, and a power unit box 11 is provided on each of the left and right side wall surfaces of the heat preservation pipe 10. The side wall surfaces of the two power unit boxes 11 close to each other are both in a hollow state;

[0033] includes a limiting device that can limit the heat preservation pipe 10. The limiting device includes two groups of rubber pads 16. The two groups of rubber pads 16 are respectively provided on the sides of the two power unit boxes 11 close to each other. The number of each group of rubber pads 16 is four, and the rubber pads 16 are arc-shaped;

[0034] It includes a moving device that can move multiple rubber pads 16. The moving device includes two bolts 19 and two groups of L-shaped plates 15. The two bolts 19 and the two groups of L-shaped plates 15 are respectively located at the cavity positions of the two motor boxes 11. The number of each group of L-shaped plates 15 is four.

[0035] During specific use, the limiting device can limit the heat preservation pipe 10 through the two groups of rubber pads 16, and the moving device can move the multiple rubber pads 16, so as to enable the rubber pads 16 to cope with heat preservation pipes 10 of different specifications.

[0036] In summary, by setting the limiting device and the moving device, the limiting device can limit the heat preservation pipe 10, and the moving device can cope with heat preservation pipes 10 of different specifications. Compared with the prior art, it has the characteristics of convenient use and simple structure.

[0037] As Figure 2 、 Figure 3 、 Figure 4 and Figure 6 shown, two support rods 13 are fixedly installed on the bottom wall surfaces of the two motor boxes 11, and a chassis 14 is fixedly installed on the common bottom wall surfaces of the two support rods 13. A T-shaped hole 12 is opened on the side wall surfaces of the two motor boxes 11 close to each other.

[0038] Both of the two bolts 19 penetrate through the side wall surfaces of the two motor boxes 11 far from each other. Four limiting rods 22 are fixedly installed in an annular array on the side wall surfaces of the two motor boxes 11 close to each other in the cavity.

[0039] A first moving block 20 is arranged in each of the two motor boxes 11. Four second moving blocks 21 are fixedly installed on the side wall of the first moving block 20 at equal intervals. All four limiting rods 22 penetrate through the corresponding second moving blocks 21. The bolt 19 penetrates through the first moving block 20 and is in threaded connection with the penetration part of the first moving block 20.

[0040] During specific use, when the staff rotates the bolt 19, it can drive the first moving block 20 in threaded connection with it to move. The movement of the first moving block 20 can drive the second moving block 21 to move. The second moving block 21 cannot rotate due to the limitation of the limiting rod 22, so that the first moving block 20 cannot rotate. When the second moving block 21 moves back and forth, it can drive the multiple rubber pads 16 to move closer to or away from each other. The specific moving method will be discussed below. The support rods 13 and the chassis 14 can both limit the motor boxes 11.

[0041] In summary, by setting the heat preservation pipe 10, T-shaped hole 12, chassis 14, bolt 19, first moving block 20, second moving block 21 and limiting rod 22, the rotation of the bolt 19 can be used to control the movement of multiple second moving blocks 21. The movement of multiple second moving blocks 21 drives multiple rubber pads 16 to move away from or close to each other, so as to cope with heat preservation pipes 10 of different specifications. It is convenient to use and has a simple structure.

[0042] As Figure 3 , Figure 4 and Figure 5 shown, the four L-shaped plates 15 are all arranged in an annular array on the side wall of the bolt 19. T-shaped blocks 17 are fixedly installed on the side walls of the two groups of L-shaped plates 15 that are away from each other, and multiple T-shaped blocks 17 are all connected to the corresponding T-shaped holes 12.

[0043] The side walls of the multiple L-shaped plates 15 that are close to each other are all arc-shaped and are inclined from the inside to the outside from the side close to the heat preservation pipe 10 to the side away from the heat preservation pipe 10.

[0044] A spring 18 is fixedly installed on the side wall of each of the multiple L-shaped plates 15 that are away from each other, and the other ends of the multiple springs 18 are fixedly connected to the inner wall surface of the cavity of the support rod 13.

[0045] During specific use, when the second moving block 21 moves, the multiple L-shaped plates 15 can be pushed to move through the inclined surfaces and arc shapes of the multiple L-shaped plates 15. The springs 18 and T-shaped blocks 17 can both play a role in limiting the L-shaped plates 15. When the L-shaped plates 15 move, the rubber pads 16 can be driven to move. By pressing the side walls of the multiple rubber pads 16 that are away from each other against the inner side wall of the cavity of the heat preservation pipe 10, the heat preservation pipe 10 can be limited. When the second moving block 21 moves to a position away from the heat preservation pipe 10, the L-shaped plates 15 can be automatically reset by the acting force of the springs 18, and the T-shaped holes 12 are used to limit the T-shaped blocks 17.

[0046] In summary, by setting the L-shaped plates 15, rubber pads 16, T-shaped blocks 17 and springs 18, the heat preservation pipe 10 can be limited by attaching and pressing the side walls of the multiple rubber pads 16 that are away from each other against the inner side wall of the cavity of the heat preservation pipe 10. It is convenient to use and has a simple structure.

[0047] It can be understood that the present utility model is described through some embodiments. Those skilled in the art will know that without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present utility model.
