The rope lifting means 100 may be installed at a selected portion of the exit from the inlet of the platform into which the electric vehicle enters. 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.

An auxiliary roller 123 is installed on the upper side of the main body 110 so that the first connection port 122 connected to the driving member 120 is smoothly circulated and connected to the first pulley 150 or the second pulley 151 .

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.

The rope support has a plurality of rotating pulleys 132, 133, 142, and 143 mounted to the blocks 130 and 140 to rotationally support the wire rope 200, and each wire rope 200 has a plurality of rotating pulleys. 132, 133, 142, and 143 may be circulated and installed so as to be alternately wound in a horizontal direction. 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.

On the other hand, the first and second rotating pulleys 132 and 142 and the second rotating pulleys 133 and 143 are vertically arranged in parallel to each other, as in the rope ascending / descending unit 100 shown on the right side of FIG. It can be disposed inside or outside.

The blocks 130 and 140 shown on the left side of FIG. 3 include tension adjusting parts 135 and 145 for adjusting the tension of the wire rope 200 while interconnecting the wires wound around the first rotating pulleys 132 and 142 ).

The tension of the rope wire 200 connected to each of the blocks 130 and 140 by one of the tension adjusting parts 135 and 145 can be easily adjusted. For example, the tension adjusting portions 135 and 145 may be tension springs, and may be implemented in various other forms.

As such, the wire rope 200 connected by the rope support is rotatably supported by the plurality of rotation pulleys 132, 133, 142, and 143 so that the degree of freedom is circulated through the rotation pulleys 132, 133, 142, and 143. Is given.

Therefore, when two blocks 130 and 140 are elevated while overlapping each other as shown in FIG. 9, when a human body A such as a passenger's hand or arm is caught between the wire ropes 200, As the rotary pulleys 132, 133, 142, 143 rotate, the rope 200 is stretched.

Therefore, in the case of the conventional wired connection structure in which the wires W of the rope wire 200 are connected to each other as shown in FIG. 11, only one wire can be stretched when the person A is stuck, The number of wires can be increased while rotating, so that the pain is relatively small and the risk of injury is reduced.

In addition, as shown in FIG. 10, in the case where the blocks 130 and 140 are unfolded and block the entry of passengers, even if a person bumps, the tensions T1 and T2 applied to the respective wires of the wire rope 200. Since they are identical to each other, as shown in FIG. 11, there is no difference in connection structure and displacement of a conventional wire rope in which each wire W is individually connected. Thus, this embodiment can achieve its original purpose of safely blocking the passenger from the platform.

Figure 12a shows the configuration of the electric vehicle platform safety device according to an embodiment of the present invention.

As for the electric vehicle platform safety device, the rope lifting means 100 shown in FIG. 2 is arrange | positioned at the left and right, respectively, and the wire rope 200 is connected between them. The rope lifting means on the left is indicated by reference numeral 101, and the rope lifting means on the right is indicated by reference numeral 102. The wire rope 200 may be divided into a plurality of segments 201 to 206. Each segment 201 to 206 may be divided by rotating pulleys 132, 133, 142, and 143. Each segment 201 to 206 may be provided with stoppers 231 and 232. In FIG. 12A, the stoppers 231 and 232 may be disposed and installed in the main body 110, and may be spaced apart from the case portion of the main body 110 by a predetermined interval. The stoppers 231 and 232 may be tightly coupled with the wire rope 200.

12B and 12C illustrate an example of a method of coupling the stopper 231 to the wire rope 200. The stopper 231 may be configured of a front side 231a and a rear side 231b. After installing the wire rope 200 between the pair of rope lifting means 100, the front side 231a and the rear side 231b of the stopper 231 as shown in Figure 12b with the wire rope 200 in between. Can be combined. The front piece 231a and the rear piece 231b may be bonded and bonded together, and the front piece 231a and the rear piece 231b may include an elastic material. Alternatively, the front side 231a and the rear side 231b are provided with holes, and the front side 231a and the rear side 231b may be coupled by tightening bolts and nuts through the holes, in which the front side 231a and the rear side 231b may be made of a hard material. In the embodiment where the stoppers 231 and 232 have a disk shape, the diameters of the stoppers 231 and 232 are defined by the holes of the body 110 formed to pass the wire rope 200. It may be larger than the diameter. The stopper 232 may be described similarly to the stopper 231.

Referring back to FIG. 12A, when the point BP of the segment 201 is broken, the wire rope 200 (including the tension adjusting unit 145) contracts based on the center point O of the wire rope 200. can do. Thus, segments 201-206 can move to the right and / or left, respectively. In this case, the stoppers 231 and 232 are not only tightly coupled to the wire rope 200 but also larger than the holes of the main body 110 formed to pass the wire rope 200. 232 is caught in the main body 110. Therefore, the moving distance of each segment 201 to 206 may be limited. If the stoppers 231 and 232 are not present, both cut ends of the segment 201 may swing back and forth while moving in the left and right directions, respectively, which may cause injuries to those around them. . The presence of stoppers 231 and 232 reduces this risk.

FIG. 13 illustrates a case in which the stoppers 231 and 232 are disposed outside the main body 110 in the modified embodiment of FIG. 12A.

14A to 14D show various examples of side cross-sectional views of the gap preventing means 220 shown in FIG.

In the gap preventing means 221 shown in Fig. 14A, the diameter of the uppermost hole H1 is φ1, and the diameters of the other holes H2 to H6 are φ2 (but φ2> φ1). At this time, the diameter of the hole (H1) is less than or equal to the diameter of the wire rope 200 passing through the hole (H1), so that the gap prevention means 221 and the wire rope 200 is firmly coupled together It is designed to move. On the other hand, the diameter of the holes (H2 ~ H6) is larger than the diameter of the wire rope 200, so that the wire rope 200 can freely move left and right in the holes (H2 ~ H6). In FIG. 14A, the diameter of the uppermost hole H1 is the smallest. However, in the modified embodiment, the diameter of any of the plurality of holes H1 to H6 may be smaller than the diameter of the remaining holes.

In the gap preventing means 222 shown in Fig. 14B, the diameter? 1 of all the holes H1 to H6 is equal to or smaller than the diameter of the wire rope 200 passing through each hole.
