At this time, the adjustable supporting structure 3 is in a working state, and the end platform at the upper part can gradually move upwards under the guiding action of the guide shaft 10 by controlling the extension rod of the oil cylinder 9 to extend out. When the working position is reached, the oil cylinder 9 stops extending out of the telescopic rod continuously. When the end station is erected, one end of the end station can leave the rail surface, and the No. 1 platform plate is inserted into the lower part of the platform erected on the straight top.
When the end platform does not work any more, the telescopic rod of the control oil cylinder 9 is retracted, and the end platform begins to gradually descend. After the platform is descended, the platform end span 2 is controlled to be folded and retracted, and meanwhile, the adjustable supporting structure 3 is retracted into a gap between the platform end span 2 and the platform midspan 1 to wait for the next work.
