[0025] In this embodiment, the linear drive component 6 is configured as a hydraulic cylinder, the fixed end of the linear drive component 6 is hinged to the base frame 1, and the action end of the linear drive component 6 is hinged to the bottom surface of the support plate 3; by controlling the linear drive component 6 and extending or shortening its action end, the support plate 3 can be driven to rotate around the axis of the rotating shaft 2, thereby adjusting the inclination angle of the support plate 3.

[0026] The working process of the above technical solution is: place the insulation pipe to be injected with polyurethane on the supporting seat 5, and make one end of it rest on the limit plate 4; fix the top of the insulation pipe through the fixing component 2 9, and then adjust the angle of the support plate 3 through the linear drive component 1 6; after the angle of the support plate 3 is adjusted, insert one end of the injection tube 11 from the higher side of the insulation pipe to the lower side of the area to be injected; then fix the injection tube 11 on the fixing component 8, and then start the polyurethane injection operation.
