The hydraulic station is started, the two sets of oil cylinders are simultaneously opened, and the steel pipe is clamped by the clamp. And the pipe conveying trolley falls and retreats to the initial position to wait for conveying the steel pipe next time. The spraying trolley rapidly advances, the trolley stops walking when reaching the intermediate frequency heating position, and the clamp rotates to drive the steel pipe to rotate. And the intermediate frequency coil descends and stops when reaching a proper position, then the intermediate frequency equipment is started to heat, and the spraying trolley starts to walk. When the cart is advanced to the proper position, the applicator is started. Observing the distance between the tail of the steel pipe and the intermediate frequency coil, and starting the intermediate frequency coil walking motor at a proper position to ensure that the relative position of the coil and the steel pipe is unchanged, which is equivalent to that the intermediate frequency coil follows the steel pipe to move forward and simultaneously supplements heat for the tail area of the steel pipe. After the whole steel pipe and the clamp are sprayed, the spraying trolley is switched to a fast-forward state in a slow-speed walking mode, quickly reaches the lower pipe position and stops advancing. Then, manually pressing down the disc cutter to separate the clamp from the foam on the surface of the steel pipe. And after the cutting is finished, stopping rotating the steel pipe. The lower pipe conveying trolley retreats to the position right below the foam pipe and stops, and the V-shaped block of the pipe conveying trolley rises and stops after being close to the foam (the rising height is adjusted in advance according to the thickness of the foam layer and the like). The two sets of oil cylinders retract simultaneously, and the clamp loosens the steel pipe. The driving trolley and the driven trolley respectively (or simultaneously) leave the end part of the steel pipe, the front end face of the clamp retreats from the steel pipe, and the two trolleys stop retreating after the distance between the front end face of the clamp and the end face of the steel pipe is 200 mm. The lower pipe conveying trolley lifts the foam pipes to advance to the curing platform. And after the pipe conveying trolley completely leaves the spraying trolley, the spraying trolley rapidly retreats and stops when walking to the initial pipe feeding position.
