[0041] When the moving assembly 6 is in the dominant side, the moving assembly 6 will move downwards, the locking assembly 7 will be separated from the buffer assembly 11, under the action of gravity of the locking assembly 7, the steel cable II 10 will be pulled tight, the rope tension detector II 82 will detect the tension of the steel cable II 10 and transmit it to the central control module 4, and then the central control module 4 controls the power assembly 5 to start and release the steel cable II 10 at a proper rotating speed, so that the locking assembly 7 is in contact with the buffer assembly 11 again, thereby making the locking assembly 7 always adhere to the buffer assembly 11.
