Description

{Safety equipment of train platform}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to safety equipment for a train, and more particularly, to a safety device installed in a train platform.

In general, the platform of the subway or railway is left open to the rail side for passengers to board the train. Therefore, there are frequent safety accidents such as falling passengers falling on the track, crashing cars that enter the train and passengers.

In order to prepare for such a safety accident, the safety line is marked with yellow on the ground of the platform to induce passengers to retreat behind the safety line.

However, the safety line can only raise the alarm to allow passengers to retreat behind the safety line and does not actively prevent safety accidents in which passengers fall on the track or collide with electric cars.

Therefore, in recent years, as a platform safety device for electric vehicles, a fixed wall and a movable door are installed between platform tracks, and a screen door that can be opened and closed by interlocking with the entrance of an electric vehicle when the vehicle is stopped prevents the accident more proactively. I can do it.

However, the conventional screen door is manufactured and installed cost increases because a plurality of doors are installed so as to correspond to the position of the door of the train, and the screen door does not operate when the stop position of the train and the position of the screen door does not match. There is a problem that the passengers are inconvenienced by delaying the getting on and off time of the electric vehicle.

In addition, a conventional screen door-type electric vehicle platform stabilizer is controlled by an electric vehicle and an ATO (Automatic Train Operating) system. The ATO system can be applied only to a platform of a new or recently constructed subway, so the subways installed in the past There is a problem that can not use the screen door on the track.

As a technology capable of solving the problems of the conventional screen door, Korean Patent No. 0601 012 "Safety Device for Electric Vehicle Platform" is disclosed.

A plurality of rope lifting means 100 are installed so as to be separated from each other by a predetermined distance and are connected to the wire rope 200. The rope deflection preventing means 300 also serves as a support, Can be installed in an appropriate number between the descending means (100). According to an embodiment, the rope sag prevention means 300 may be omitted.

That is, the rope lifting means 100 is installed on the safety line of the subway or railway where the passenger waits for the riding of the electric vehicle, and when the electric vehicle reaches the riding position, the passenger who is waiting on the platform by raising the wire rope 200. It is possible to ride on the electric vehicle, and when the ride is completed and the electric vehicle is to depart to serve to ensure the safety of the passengers by lowering the wire rope 200. Therefore, the rope lifting means 100 may also be referred to as a Rope Screen Door ("RSD").

 3, the rope lifting means 100 includes a main body 110 erected upright on a platform, a main body 110 vertically moved along the main body 110 and connected to the wire rope 200 At least two blocks 130 and 140 and a driving member 120 for moving the blocks 130 and 140. In the present embodiment, two blocks 130 and 140 are provided as a pair, and as shown in FIG. 5, a first block 130 located on the back of the main body 110, and a second block 130 located on the front of the main body 110 And a second block 140 as shown in FIG.

In the modified embodiment, it can be understood that three or more blocks may be installed in one body 110.

A first pulley 150 connected to the upper end of the main body 110 through a first block 130 and a second coupling 152 and a second pulley 150 fixed to one side of the first pulley 150, The second pulley 151 may be connected to the first pulley 150 through the second coupling 152 and the second pulley 151 may be smaller or larger than the diameter of the first pulley 150. That is, the first pulley 150 and the second pulley 151 may have different diameters.

When the first pulley 150 and the second pulley 151 that are smaller or larger than the diameter of the first pulley 150 rotate at the same time due to the operation of the driving member 120, The distance between the first block 130 and the second block 140 can be adjusted to be different from each other.

At this time, the diameters of the first pulley 150 and the second pulley 151 overlap with each other when the wire rope 200 rises according to the movement distance and position of the wire rope 200, .

The first pulley 150 and the second pulley 151 are formed to have the same number according to the number of the blocks 130 and 140 and are made to have different diameters. Can be adjusted. For example, two pulleys having different diameters may be provided when the number of blocks is two, or three pulleys having different diameters may be provided when the number of blocks is three.

For example, the first pulley 150 and the second pulley 151 may be smoothly rotated gears or pulleys. The second pulleys 152 may be connected to the first pulleys 150 and 150, A flexible belt or a rope or the like may be used so as to be wound or unwound on the outer diameter of the two pulleys 151. [

Here, the first pulley 150 and the second pulley 151 can smoothly ascend and descend the two or more blocks 130 and 140 by using one driving member 120.

Various means such as a motor capable of rotating the first pulley 150 or the second pulley 151 can be applied to the driving member 120. However, in this embodiment, maintenance and repair are easy, The cylinder can be used.

A heavy load 121 is mounted on the rod of the cylinder and a first connecting hole 122 may be connected between the rod of the cylinder and the first pulley 150 or the second pulley 151. More specifically, the rod may be formed on both sides of the cylinder so that the heavy material 121 may be mounted on one rod and the first connector 122 may be connected to the rod on the other side. The first connection port 122 may be a flexible belt that is connected to the first pulley 150 or the second pulley 151 and is rotatable.

In particular, the heavy object 121 can lower the rod of the cylinder by the self-weight during a power failure or an emergency, so that the blocks 130 and 140 and the wire rope 200 are elevated so that passengers can safely escape. At this time, the heavy object 121 may be configured to be assembled or disassembled as a plurality of heavy objects having a predetermined weight in order to control the weight of the worker.

Therefore, simultaneously with the operation of the driving member 120, the blocks 130 and 140 and the wire rope 200 are lowered by their own load, thereby preventing the passengers from entering and exiting. Conversely, by the reverse operation of the driving member 120, So that the passenger 200 can be elevated so that the passenger can go in and out.

That is, when the passenger enters and exits, the blocks 130 and 140 remain in the upper state as shown in FIG. 6, but when the passenger is shut off, the blocks 130 and 140 descend in the downward direction as shown in FIG. So that the wire rope 200 is prevented from entering and exiting the passenger.

On the other hand, rails 111 and 112 for guiding the movement paths of the blocks 130 and 140 in the vertical direction may be installed on one side of the main body 110, respectively. The first rollers 131 and 141 may be formed inside the blocks 130 and 140 so as to move along the rails 111 and 112 while being rotated. For example, the first rollers 131 and 141 may use a linear motion member such as an LM block and an LM guide that can slide along the rails 111 and 112. [

As shown in FIG. 5, the rails 111 and 112 and the first rollers 131 and 141 may be installed so that the wire rope 200 and the center of the first rollers 131 and 141 are aligned with each other when viewed in plan view. When the center positions of the rails 111 and 112 and the first rollers 131 and 141 and the center positions of the wire ropes 200 are different from each other in the course of raising and lowering the wire rope 200 in a state in which a constant tension is maintained, The blocks 130 and 140 and the wire ropes 200 can not smoothly rise and fall due to concentrated bias loads and torsional phenomena, and frequent failures are caused, thereby providing a cause of safety accidents.

As shown in FIG. 2, the wire rope 200 may be continuously connected from the inlet of the platform to the main body 110 on the other side of the main body 110 installed at the selected portion of the outlet. The ends of the wire rope 200 are connected to the blocks 130 and 140 moved up and down along the main body 100. The first blocks 130 and the second blocks 140 have two rows The wire ropes 200 having the wires arranged above are respectively mounted.

For example, the surface of the wire rope 200 may be coated with a rubber or synthetic resin material for insulation. In addition, the detailed configuration of the wire rope 200 will be described later.

As shown in FIG. 6, the wire rope 200 needs a gap preventing means 220 to connect the wires arranged in two or more rows to each other in the vertical direction to prevent shaking during lifting and lowering of passengers efficiently. It may be installed further depending on.

For example, the gap preventing means 220 is made of cloth or synthetic resin material, etc. to connect a plurality of wire ropes as a whole, to prevent gaps or shaking, and when the body of the passenger touches the flexibility It can secure safety accidents.

7, the ratchet wheel 153 is coupled to one side of the first pulley 150 or the second pulley 151, and the ratchet wheel 153 is coupled to one side of the main body 110 around the hinge shaft 161 The stopper 160 can be further mounted so as to be rotatable in the left-right direction.

The ratchet wheel 153 can be engaged with the ratchet wheel 153 at one side and the first connecting port 122 connected to the first ratchet 150 or the second ratchet 151, The support roller 162 can be mounted.

Therefore, the support roller 162 normally rotates while abutting against the first connection port 122, so that the retaining member 160 is kept apart from the ratchet wheel 153 by a predetermined distance. When the first connection hole 122 is cut off, the latch 160 is rotated about the hinge shaft 161 by the weight of the support roller 162 and is engaged with the ratchet wheel 153, The first and second pulleys 150 and 151 can be stopped to prevent a safety accident that occurs when the blocks 130 and 140 and the wire rope 200 are suddenly lowered.

8, a plurality of locking grooves 170 are formed in the interior of the main body 110 in the vertical direction and a plurality of locking grooves 170 are formed in the main body 110 such that the locking grooves 170 are rotatable about the rotation axis 172 formed on one side of the blocks 130, A locking protrusion 171 connected to the second connector 152 may be mounted on the upper portion of the main body 110. [

When the second connecting hole 152 is cut, the engaging protrusion 171 is rotated in one direction around the rotating shaft 172 and is inserted in the engaging groove 170 so that the blocks 130 and 140 and the wire rope 200 are suddenly It is possible to prevent a safety accident occurring while descending.

Meanwhile, as shown in FIG. 3, the above-described wire rope 200 forms a plurality of rows and includes blocks 130 and 140 provided in one main body 110 and blocks provided in the other main body 110. 130, 140 may be fastened by a rope support.

That is, one wire rope 200 may be connected to each of two blocks 130 and 140 to have a closed curve.

The plurality of rotating pulleys 132, 133, 142 and 143 may include first and second rotating pulleys 132 and 142 and second rotating pulleys 133 and 143.

At least two first pulleys 132 and 142 may be mounted to rotate and support a row of wires arranged out of the plurality of rows of wire ropes 200. In the present embodiment, each wire rope 200 connected to the blocks 130 and 140 is illustrated to form six rows, but is not limited thereto and may be variously modified.

For example, in the wire rope 200 consisting of six rows as in the present embodiment, the rows arranged on the outside mean 1 row and 6 rows, and the rows arranged on the inside mean 2 rows to 5 rows. In addition, when referring to the region of the wire rope 200 of any one row arranged in each row, it will be referred to as wire for convenience.

At least two of the second rotary pulleys 133 and 143 may be mounted to rotatably support a row of wires arranged in the inner side of the plurality of rows of wire ropes 200.

The first rotating pulleys 132 and 142 are disposed inside the block and the second rotating pulleys 133 and 143 are disposed on the inner side of the blocks 130 and 140 as shown in the left- As shown in Fig. Two first rotating pulleys 132 and 142 and four second rotating pulleys 133 and 143 are mounted on one block 130 and 140 of the present embodiment. Here, the inside of the blocks 130 and 140 means a portion adjacent to the rails 111 and 112, and the outside of the blocks 130 and 140 refers to a portion adjacent to the facing blocks 130 and 140.
