Description

  The present invention relates to a train platform safety device, and more particularly, a wire rope and a guide as well as a block connected with a wire rope can be lifted to block passengers from entering and exiting according to the boarding position of the train. A train platform safety device (sometimes referred to as “RSD” hereinafter) that allows members to be installed so that their centers are aligned with each other in plan view to prevent twisting and distortion in advance. It is for providing.

  In general, the subway or railway platform is in a state where the track side is opened so that passengers can board the train, so there are frequent crash accidents where passengers fall into the track and collisions with entering trains. Has occurred. Therefore, as a means for preventing this, a safety line is displayed in yellow on the ground of the platform so that the passenger can stand behind the safety line.

  However, the safety line only plays a role of guiding behind the safety line for personal safety, and substantially prevents safety accidents where passengers fall on the track or collide with the train. It does not have a shut-off function.

  For this reason, recently, a fixed wall and a movable gate are installed between the platform and the track, and a screen door is provided so that the movable gate can be opened and closed in conjunction with the entrance and exit of the train when the train stops. By trying to prevent passenger crash and safety accidents.

  Dozens of such conventional screen doors are installed to correspond to the entrance / exit position of the train, so the production and initial installation costs are high, and the screen door operates according to the stop position of the train. Therefore, when the stop position of the train does not coincide with the position of the screen door, the screen door does not operate, resulting in a delay in getting on and off the train, resulting in inconvenience for passengers.

  In particular, when the power is shut down in an emergency situation such as a fire accident in the subway, the screen door will not operate, which may cause a large disaster by blocking the exit from which passengers can escape. There is.

  In addition, the screen door is controlled by a train and an ATO (Automatic Train Operating) system. Such an ATO system can be applied only to a subway platform that is currently newly constructed or recently constructed. However, since the screen door cannot be used in a subway that has been constructed in the past and does not currently apply the ATO system, the use efficiency and range of use of the screen door must be extremely limited. Yes.

  Therefore, conventionally, as a method for solving the above-mentioned problems, a safety device for a train platform filed by the present inventor is disclosed in Korean Patent No. 0601112 (July 19, 2006).

  However, as shown in FIG. 2, the wire rope 200 and the rail 20 are installed so that their center positions are different from each other in plan view, and the load is concentrated on one side, and not only the torsion phenomenon but also an eccentric load is generated, resulting in durability. And there is a problem that the service life is shortened.

  That is, in order to maintain the strong tension of the wire lobe 200 reaching several tens of meters according to the length of the train platform, a load is applied to the block 130 and the rail 20 that relatively connect and support both ends of the wire rope 200. Since it is obvious to concentrate, there is an urgent need for a method that can maintain the tension of the wire rope 200 and move smoothly in the vertical direction.

  On the other hand, conventionally, since the rail 20 and the guide shaft 10 are easily deformed due to an offset load, the tension of the wire rope 200 cannot be kept constant, and as a result, an essential function for blocking passengers from entering and exiting is performed. There was a problem that it was not possible.

  Furthermore, because of the characteristics of the linear reciprocating member that moves along the rail 20, a separate supply pipe and a greasing device for supplying the lubricating liquid (grease) are required. There was a problem that contamination occurred.

  In particular, there is a problem that maintenance is difficult due to complicated structure and frequent failures.

A plurality of wire ropes 200 installed in a horizontal direction so as to be connected to each other and the wire rope lifting means 100 are spaced apart from each other at a fixed interval, and prevent the wire rope 200 from slackening and in the vertical direction. In a train platform safety device comprising a number of wire rope slack prevention means 300 for guiding smooth movement,

  The wire rope lifting / lowering means 100 moves in a vertical direction along the guide member 120, a body 110 installed in a vertical direction on the ground, a guide member 120 installed in a vertical direction on one side of the body 110, and the like. In a plan view, the wire rope 200 is connected to the center of the guide member 120 so that the wire rope 200 is aligned with the center of the guide member 120, and is installed rotatably on the upper side of the body 110. And a pulley member 140 for moving the block 130 in the vertical direction according to the rotation direction, and a driving member 150 installed on one side of the body 110 for rotating the pulley member 140.

  In the present invention, the wire rope lifting / lowering means 100 is installed on a safety line of a subway or a railroad where passengers wait for boarding of a train, and when the train reaches a boarding position, the wire rope lifting / lowering means 100 lifts the wire rope 200, When the passenger waiting on the platform can get on the train, and when the ride is completed and the train is about to leave, the wire rope 200 is lowered to ensure the safety of the passenger.

  Here, the pulley member 140 can smoothly raise and lower the block 130 while rotating by the operation of the driving member 150.

  That is, when a passenger enters and exits, as shown in FIG. 3, the block 130 is kept in an upward state, and when a passenger is blocked, the block 130 is lowered downward as shown in FIG. 5. However, the wire rope 200 blocks passengers from entering and exiting.

  At this time, the diameter of the pulley member 140 can be selectively determined so that the movement distance of the wire rope 200 can be adjusted by the operation of the driving member 150.
