The worker moves the disassembled heat preservation pipe needing to be renovated to the right below the carrying mechanism through the mechanical arm. The controller sends a signal to the heat preservation pipe fixing mechanism, and the heat preservation pipe fixing mechanism receives the signal and then drives the pair of three-jaw chucks to be inserted into the inner wall of the heat preservation pipe and tensioned, so that the heat preservation pipe is fixed. At the moment, the section of the heat preservation pipe shaft and the working end of the cutting mechanism are positioned on the same plane, and the surrounding mechanism and the peeling mechanism are symmetrical about the plane.

The working end of the stripping mechanism is attached to both sides of the working end of the cutting mechanism and is cut into the incision together in the process of cutting the heat insulation layer by the working end of the cutting mechanism. When the cutting mechanism descends to the tail end of the stroke, the controller sends a signal to the stripping mechanism, and the stripping mechanism receives the signal and strips the heat-insulating layer along the peripheral wall of the working steel pipe at the innermost layer of the heat-insulating pipe in an arc-shaped motion mode by separating the working ends of the stripping mechanism from each other. Then the controller sends a signal to the carrying mechanism, the carrying mechanism drives the mounting frame to drive the cutting mechanism, the encircling mechanism and the stripping mechanism to move to the other end of the heat preservation pipe along the axial direction of the heat preservation pipe after receiving the signal, finally the cutting mechanism cuts the whole heat preservation layer, and the stripping mechanism strips the heat preservation layer from the working steel pipe.
