Description

Electric Vehicle Platform Safety Device

The present invention relates to an electric vehicle platform safety device, and more particularly, by lowering the block connected to the wire rope can block the entrance of the passenger according to the riding position of the electric vehicle, as well as the center of the wire rope and the guide member in a flat state It is to provide an electric vehicle platform safety device (Rope Screen Door, "RSD") that can be installed in a straight line with each other to prevent twisting and deformation in advance.

In general, the platform of the subway or railroad is open to allow passengers to ride on electric cars, so passengers frequently fall into the tracks and accidents that collide with the entering electric cars frequently occur. As a means of doing this, yellow lines on the platform of the platform are marked with safety lines to allow passengers to retreat behind the line.

However, the above-mentioned safety line only raises an alarm to retreat behind the safety line for personal safety, and does not substantially prevent a safety function to prevent passengers from falling on the track or colliding with an electric vehicle.

Therefore, recently, a fixed wall and a movable door are installed between the platform and the track to install a screen door that allows the movable door to be opened and closed in conjunction with the entrance door of the electric vehicle when the electric vehicle stops, thereby preventing passengers from falling and safety accidents. I'm trying to.

Such conventional screen doors require a lot of manufacturing and initial installation costs because dozens are installed to correspond to the door position of the electric vehicle, and the screen door is operated according to the stop position of the electric vehicle, so the stop position of the electric vehicle is the screen door. If it does not match the position of the screen door is not operated, and eventually the time to get on and off the train is delayed has a problem that causes inconvenience to the passengers.

In particular, when the power is cut off in an emergency situation such as a fire accident in the subway, the screen door is not operated, which causes a problem that causes a large disaster due to the blockade of the exit where the passenger can escape.

In addition, the screen door is controlled by an electric vehicle and an ATO (Automatic Train Operating) system, which can be applied only to a platform of a newly built or recently constructed subway, and has been built in the past and is currently used in the ATO system. In the subway that does not apply to the screen door can not be used, the use efficiency and utilization range of the screen door is finally limited to have a problem.

Since this concentration is self-explanatory, after all, there is an urgent need for a method of maintaining the tension of the wire rope 200 and moving smoothly in the vertical direction.

On the other hand, the conventional rail 20 and the guide shaft 10 is easily deformed due to the unbalanced load can not maintain a constant tension of the wire rope 200 can not perform the essential function to eventually block the passengers access Got

In addition, in the related art, a separate supply pipe and a feeding device for supplying a lubricating liquid (grease) are required due to the characteristics of the linear reciprocating member moving along the rail 20. Thus, there is a problem of severe contamination due to overfeeding and leakage.
