The last part is clamped so that the insulation layer can be fixed on the surface of the pipe 1 for insulation, which effectively prevents the insulation layer from having gaps resulting in poor insulation effect and increases the use effect of the insulation layer. A mounting block 14 is bolted to one side of the clamping plate 10, and a fixing mechanism 15 is provided on one side of the mounting block 14. With the cooperation of the mounting block 14 and the fixing mechanism 15, the position of the clamping plate 10 can be fixed, thereby preventing the clamping plate 10 from being offset during operation, increasing the stability of the clamping plate 10 during operation and increasing the use effect of the insulation layer.

[0024] The limiting mechanism 4 includes a first rotating disk 41, one side of the first rotating disk 41 passes through one side of the flange shell 2 and is rotatably connected to the penetration point, a worm 42 is fixed to one side of the first rotating disk 41, and a worm wheel 43 is meshed with one side of the worm 42. The inner cavity of the worm wheel 43 is fixedly connected to the surface of the transmission shaft 5. Under the cooperation of the first rotating disk 41 and the worm 42, the worm wheel 43 can drive the spur gear 6 to rotate through the transmission shaft 5, and the spur gear 6 drives the limiting plate 3 to move toward the direction of the pipeline 1 on one side of the flange shell 2 through the rack plate 7, so as to limit the beginning of the installation of the thermal insulation layer, facilitate the installation of the thermal insulation layer by the staff, reduce the labor of the staff, and thus speed up the installation of the thermal insulation layer by the staff.

[0026] Working principle: when the staff needs to install the insulation layer on the surface of the pipeline 1, the staff first places the beginning of the insulation layer on one side of the limit plate 3, and then drives the worm 42 to drive the worm wheel 43 to rotate through the first turntable 41, and the worm wheel 43 drives the spur gear 6 to drive the rack plate 7 to move in the inner cavity of the guide block 8 through the transmission shaft 5, and the rack plate 7 drives the limit plate 3 to move in the direction of the pipeline 1, thereby clamping the beginning of the insulation layer, and then after the insulation layer is rotated one circle, the staff manually pushes the clamping plate 10 to move the slider 13 on the surface of the guide rod 12, and at the same time, the clamping plate 10 drives the moving rod 153 to move in the direction of the corresponding hole 154 through the mounting block 14. When the moving rod 153 and the corresponding hole 154 correspond to each other, under the action of the rebound of the tension spring 152, the moving rod 153 can enter the inside of the corresponding hole 154, thereby fixing the clamping plate 10 and clamping the insulation layer. When the installation is completed, the staff can install the insulation layer on the next section of the steam pipeline.
