On the contrary, when the railroad cars are to be started, the wire ropes 200 are lowered to secure the safety of the passengers.

Here, the rotary pulley 150 can smoothly move up and down the block 130 while being rotated by the driving member 120. In other words, when the passenger enters and exits, the block 130 maintains the upper part as shown in FIG. 2. If the passenger is blocked, the block 130 descends downward as shown in FIG. 5, The rope 200 blocks entry and exit of the passenger. At this time, it is natural that the diameter of the rotary pulley 150 can be adjusted so that the moving distance of the wire rope 200 can be controlled by the operation of the driving member 120. Further, in the embodiment of the present invention, it is of course possible to apply a gear or a pulley which can smoothly rotate the rotary pulley 150.

For this purpose, a tension spring may be used in this embodiment.

A roller 111 may be provided at one side of the inside of the column 110 in a vertical direction and a roller 131 may be formed inside the block 130 so as to move along the rail 111 while rotating. 4, it is preferable that the rail 111 and the roller 131 are disposed so that the wire rope 200 and the center of the roller 111 are aligned with each other when viewed in plan view. That is, it is preferable that the rails 111 and the rollers 131 are disposed on an extension of the wire rope 200. This is because when the center position of the rail 111 and the roller 131 and the center position of the wire rope 200 are different from each other in the course of raising and lowering the wire rope 200 maintaining a constant tension, And the torsion phenomenon are concentrated, the block 130 and the wire rope 200 can not smoothly ascend and descend, and frequent failures occur, thereby providing a cause of a safety accident. In particular, the roller 131 can use a linear motion member such as an LM block and an LM guide that can slide along the rail 111. [

Meanwhile, various means such as a motor capable of rotating the rotary pulley 150 may be applied to the driving member 120. However, in the present invention, a cylinder is used to facilitate maintenance and to promptly and smoothly ascend and descend A heavy load 121 is mounted on the rod of the cylinder, and a connecting hole 122 is connected between the rod of the cylinder and the rotary pulley 150.
