[0002] Thermal pipes are mainly used for hot steam transportation over long distances. In order to reduce the heat loss of steam in the thermal pipe during transportation, it is often necessary to wrap a layer of thermal insulation sheath around the outside of the pipe to improve the thermal insulation performance. At present, common thermal insulation sheaths are generally composed of thermal insulation cotton and an outer shell. Workers are required to wrap the thermal insulation cotton around the outside of the pipe first, and then wrap the outer shell around the outer layer of the thermal insulation cotton. The installation is more troublesome and time-consuming. Moreover, the thermal insulation sheath forms a whole after installation, and it is more troublesome to replace and repair local areas later. Therefore, the existing technology has the problem of more troublesome installation and replacement. Summary of the invention

[0029] Preferably, reinforcing ribs are further provided in the sheath shell.

[0030] A heat-absorbing thermal insulation cotton layer and an aerogel thermal insulation layer are arranged in the first sheath and the second sheath, so as to have good thermal insulation performance; by arranging a thermal insulation coating, a corrosion-resistant coating, an anti-aging coating and a wear-resistant coating on the outer wall of the sheath shell, the thermal insulation performance can be further improved, and good anti-corrosion and wear-resistant performance can be achieved, thereby extending the service life.

Then, the installation support frame is hoisted to the position of the pipeline to be installed by the crane. After adjusting the position, the first sleeve and the second sleeve are respectively located on the upper and lower sides of the pipeline. Then, the lifting gas rod of the fixed stabilization module starts to work, so that the arc-shaped clamp acts on the adjacent first sleeve surface or the surface of the pipeline; then the bottom hydraulic lifting cylinder starts to rise, and the second sleeve is installed below the pipeline. The second groove of the second sleeve is engaged with the second annular protrusion of the adjacent second sleeve; and the upper part of the bottom hydraulic lifting cylinder cooperates with the descending force of the stabilization fixing module to achieve the fixation of the installation support frame; thereafter, the top lifting cylinder starts to work, driving the first sleeve to descend until the first sleeve descends to the contact area of ​​the pipeline, and the two-way driving hydraulic cylinder begins to expand outward, driving the L-shaped lifting plate to separate from the first sleeve. The top lifting cylinder urgently applies downward pressure to the first sleeve, so that the elastic card block of the first sleeve is inserted into the card slot of the plug-in groove to complete the installation and fixation of the first sleeve and the second sleeve. Then, the fixed stabilization module rises, and the installation support frame is lifted off, and the first sleeve and the second sleeve are installed to continue the next installation work.
