[0109] When the high-speed train stops to allow passengers to get on or off, the driving motor 034 drives the second chain 033 to lift the lifting assembly 01, and at the same time, the lifting assembly 01 is lifted, and since the first chain 013 is fixedly connected with the connecting column 037, the connecting column 037 pulls down the left side of the first chain 013, so that the right side of the first chain 013 pulls up the lower end of the scissor lifting mechanism 2, the scissor lifting mechanism 2 is contracted, and each sliding rope block moves upward to realize the synchronous lifting of the corresponding rope 02, and the shielding door formed by the rope 02 no longer separates the platform personnel from the high-speed train.

[0110] In the remaining time, the driving motor 034 drives the second chain 033 to drive the lifting assembly 01 to descend, and when the lifting assembly 01 descends, the first chain 013 is pulled up on the left side of the connecting column 037 due to the fixed connection of the first chain 013 and the connecting column 037, so that the right side of the first chain 013 pulls down the lower end of the scissor lifting mechanism 2, the scissor lifting mechanism 2 is unfolded, each sliding rope block moves downward to realize the synchronous descent of the corresponding rope 02, and the rope 02 moves downward to form a shielding door to separate the platform personnel from the high-speed train and ensure the safety of the personnel.
