Description

  The present invention relates to a technology of a platform gate that opens and closes a vehicle entrance / exit. More particularly, the present invention relates to the structure of a double slide type platform gate.

A conventional double slide type platform gate is disclosed in, for example, Patent Document 1. This is driven by a linear motor (22) in which the main door (corresponding to the first door, 2) is installed in the door pocket (1), and the slave door (corresponding to the second door, 3) is driven by the ball screw mechanism (12). This is a system that interlocks with the main door (2).
Further, as disclosed in Patent Document 2, there is known a system in which the main door (20) and the subdoor (30) are opened and closed by respective screw type drive units (50) and (60).
Further, as disclosed in Patent Document 3, first, the slave door (1) is driven by the prime mover (4) and the link mechanism (6), and the master door (2) is a locking portion ( 60) is known that moves following the slave door (1) by abutting it, and opens and closes by this.

JP 2000-108890 A (FIG. 1) Japanese Patent No. 29951648 (FIG. 2) Japanese Unexamined Patent Publication No. 2000-177580 (FIG. 2)

However, the configuration of Patent Document 1 requires two drive mechanisms, a linear motor (22) and a ball screw mechanism (12), and the configuration becomes complicated, resulting in a wide space in the door pocket (1). I can't take it.
Moreover, the structure of the said patent document 2 requires two drive parts (50, 60), and a structure becomes complicated similarly to the case of the patent document 1. FIG. In addition, there is a problem that the space in the door pocket (1) cannot be widened.
Furthermore, although the configuration of Patent Document 3 requires only one motor (4), the link mechanism (6) occupies a large space in the door pocket (3) and the space in the door pocket (3). Can't take up a lot of space. Further, since the main door (2) is locked to the slave door (1) and interlocked via the locking portion (60), the main door (2) and the slave door (1) when the door is opened and closed. The linkage operation becomes stepwise, and the opening / closing operation is not smooth.

In addition, in a see-through type platform gate, it is easy to secure a large see-through area.

(Second invention)
In the platform gate of the first invention, the sliding mechanism for guiding the sliding direction of the first door and the winding transmission body are adjacent to each other while being located on the upper end side or the lower end side of the door bag body. It is preferable to be arranged in any one (second invention).

  According to the second aspect of the invention, a large space can be secured on the center side of the space in the door pocket and on the side opposite to the side where the slide mechanism / wrapping transmission body is installed. Further, a see-through platform gate can ensure a large see-through area. Therefore, the feeling of psychological pressure on the passengers on the platform can be reduced.

(Third invention)
In the platform gate of the first invention, one of the sliding mechanism for guiding the sliding direction of the first door and the winding transmission body is arranged on the upper end side of the door bag body, It is preferable that the other is disposed on the lower end side of the door pocket body (third invention).

  According to the third aspect of the invention, a large space can be secured on the center side of the space inside the door pocket. Moreover, in the see-through type platform gate, a large see-through area can be secured. Therefore, the feeling of psychological pressure on the passengers on the platform can be reduced.

Next, embodiments of the invention will be described.
FIG. 1 is a perspective view showing a platform gate according to an embodiment of the present invention in a state where a door closes an entrance. FIG. 2 is a perspective view showing a state in which the door opens the entrance.
3 is an exploded perspective view of the platform gate, and FIG. 4 is a schematic diagram showing the relationship between the speed of the first door and the speed of the second door.

The FIGS. 1 and 2 Double sliding platform gate according to an embodiment of the present invention is shown, the platform gate 1x includes a door pocket 10, plate-like first slidably supported by the door pocket 10 One door 11 and a flat second door 12 that is slidably supported by the first door 11 are provided. The platform gate 1x is configured such that the door is opened when the train arrives at the platform, and the door is closed at other times.

  The door bag 10 will be described. The door bag body 10 is an end portion in the short direction of the platform, and is erected at a position immediately next to the entrance / exit of the railway vehicle. This door bag body 10 is formed in a hollow shape, and the inside thereof is used as a door storage space 10a. As shown in FIG. 2, the first door 11 and the second door 12 are stacked on the door storage space 10a. It can be stored in. Thus, since the platform gate 1x of this embodiment is comprised by the double slide type (double sliding door type), compared with the structure which opens and closes a single door, the width | variety of the door storage space 10a can be made small, and a door pocket The body 10 is made compact.

An opening is formed on one end in the width direction of the door bag body 10 (the entrance / exit side of the railway vehicle), and the door storage space 10a communicates with the outside through the opening. Through this opening, the first door 11 and the second door 12 can be advanced to close the entrance, and the first door 11 and the second door 12 can be retracted into the door storage space 10a to open the entrance. It is composed.
A square pipe 30 is supported horizontally above the door storage space 10 a, and a linear linear guide rail 31 is fixed to the lower surface of the square pipe 30.

  The first door 11 will be described. Two slide bearing units 32, 32 are fixed to one surface of the first door 11 via “L” -shaped brackets 33, respectively. And this slide bearing unit 32 * 32 is supported so that it may straddle the linear guide rail 31 installed in the said door body 10 side. Rolling elements such as rollers or steel balls are interposed between the slide bearing unit 32 and the linear guide rail 31, and the linear guide rail 31 and the slide bearing unit 32 constitute a so-called linear slide mechanism. As a result, the first door 11 is supported so as to be slidable in the horizontal direction with respect to the door pocket body 10.

  On the upper end side of the other side surface of the first door 11 (the surface facing the second door 12), an elongated recess 11a is formed in the horizontal direction (the direction along the advancing / retreating direction of the first door 11). Two pulleys (rotating bodies) 34 and 35 are supported in 11a. Specifically, a toothed drive pulley 34 is supported at the end of the recess 11a on the door retracting direction side, and a toothed driven pulley 35 is supported on the end of the door advancement side.

A drive unit 36 as drive means is fixed to the surface of the first door 11 opposite to the side on which the recess 11a is formed (the surface on which the slide bearing units 32 and 32 are fixed), and the drive pulley The drive output shaft of the drive unit 36 is coupled to 34. Although the specific configuration of the drive unit 36 will not be described in detail, the drive unit 36 includes an electric motor and a speed reduction mechanism that decelerates the output rotation of the motor shaft of the electric motor. The drive unit 36 is installed on the door bag body 10 side through a power supply cable (not shown). Connected to the control panel. The driven pulley 35 is supported so as to be freely rotatable.
A linear guide rail 37 is fixed to the surface of the first door 11 opposite to the surface on which the slide bearing units 32 and 32 are fixed.

  A thin guide groove 39 is cut out along the lower edge of the first door 11, while a guide roller 40 is supported on the lower portion of the inner wall of the door storage space 10 a of the door pocket body 10 so as to be freely rotatable. Is configured to roll in the guide groove 39. As a result, the first door 11 can be smoothly moved along the linear guide rail 31 and the lower portion of the first door 11 is prevented from swinging or fluttering.

  The second door 12 will be described. Two slide bearing units 38, 38 are fixed to one surface of the second door 12, and the slide bearing unit 38 straddles the linear guide rail 37 installed on the first door 11 side. Thus, it is supported so as to be linearly slidable. The linear guide rail 37 and the slide bearing unit 38 constitute a linear motion slide mechanism. As a result, the second door 12 is supported so as to be slidable in the horizontal direction with respect to the first door 11. .

  A thin guide groove 41 is cut out along the lower edge of the second door 12, and a guide roller 42 is supported at the lower end of the first door 11 so as to be freely rotatable. 41 can be rolled. This is the same purpose as the above-described configuration in which the guide groove 39 is provided in the first door 11 and the guide roller 40 is provided in the door pocket body 10, and as a result, the linear guide rail 37 of the second door 12 is formed. Smooth movement along is realized.

Next, a configuration for moving the first door 11 and the second door 12 to open and close the door will be described.
Two belt fixing members 43 and 44 are installed in the door storage space 10a inside the door pocket body 10. One belt fixing member 43 protrudes and is fixed to the upper position of the inner wall of the door storage space 10a, and one end of a flexible timing belt (winding transmission body) 45 is fixed to the tip thereof. The The other belt fixing member 44 fixes the base to the ceiling surface of the door storage space 10a as shown in FIG. 3 and is bent between the first door 11 and the second door 12 while being bent in a “U” shape. It is inserted into the gap from above and enters the recess 11a of the first door 11, and the other end of the timing belt 45 is fixed to the tip.
A midway portion of the timing belt 45 (a portion between the portions fixed by the two belt fixing members 43 and 44) is wound around the drive pulley 34 and the driven pulley 35.

  The winding structure of the timing belt 45 will be specifically described below. That is, the timing belt 45 enters the recessed portion 11a of the first door 11 while extending horizontally from the one end fixed to the belt fixing member 43 toward the door advancement direction. . The timing belt 45 is further extended horizontally in the recess 11a, and is then folded back while being wound around the driven pulley 35. The folded timing belt 45 is extended in the reverse direction (door retracting direction) in the concave portion 11 a, wound around the drive pulley 34, and then folded again, and then the end thereof is fixed to the belt fixing member 44. Is done.

  Here, on the surface of the second door 12 on the first door 11 side, a connecting fitting (connecting body) 46 is fixed in a protruding shape. The connection fitting 46 projects into the recess 11 a formed in the first door 11, and the tip of the connection bracket 46 is stretched between the driving pulley 34 and the driven pulley 35 of the timing belt 45. Fixed to.

Here, the speed relationship between the first door 11 and the second door 12 will be described with reference to the schematic diagram of FIG. 4.
FIG. 4 shows a state in which the drive unit 36 fixed to the first door 11 is driven to retract the first door 11 and the second door 12 into the door bag body 10, and the driving at this time is shown. Let the outer peripheral speed of the pulley 34 be VW. In this case, the speed V1 of the first door 11 is equal to the outer peripheral speed of the drive pulley 34 (V1 = VW). On the other hand, the speed of the stretched portion between the driving pulley 34 and the driven pulley 35 of the timing belt 45 is such that the speed V1 of the first door 11 is added to the outer peripheral speed VW of the driving pulley 34, so that V1 + VW = 2. XVW = 2 * V1. Accordingly, the speed V2 of the second door 12 connected to the extending portion via the connecting metal fitting 46 is also V2 = 2 × V1. That is, the retracting speed V2 of the second door 12 is twice the retracting speed V1 of the first door 11.
FIG. 4 shows a state in which the door is retracted (opened), but when the door is advanced (closed), the drive unit 36 may be rotated backward to rotate the drive pulley 34 in the opposite direction. Therefore, detailed description is omitted. In this case as well, the advance speed of the second door 12 is twice the advance speed of the first door 11.

  Since the platform gate 1x of the present embodiment is configured as described above, a simple configuration using a single drive unit 36 as a door drive mechanism is realized while being a double slide type. Therefore, manufacturing cost and manufacturing man-hour can be reduced. Further, since the two doors 11 and 12 are configured to move at the same time as the second door 12 at twice the speed of the first door 11, the smoothness of the operation when opening and closing the door is excellent.

Moreover, since the structure which provides this drive unit 36 in the 1st door 11 is implement | achieved, the drive unit 36 is made into what is called self-propelled which moves with the 1st door 11, and when closing a door, a drive unit with the 1st door 11 36 moves in the door storage space 10a of the door pocket body 10, and when the closing operation is completed, the drive unit 36 is positioned at the advancing side end of the door pocket body 10 as shown in FIG.
Accordingly, a transparent glass window is fitted in the door body 10, the first door 11, and the second door 12, and a so-called see-through platform gate 1 x that allows the outside of the platform to be visually recognized through these three members 10 to 12 is formed. In the case where the door is closed as shown in FIG. 1, an area on the door retracting direction side of the door bag body 10 (an area indicated by a symbol A in FIG. 1) is disposed inside the door storage space 10 a with the timing belt 45, Except for the square pipe 30 and the linear guide rail 31, the area can be almost empty. In other words, in this area A, a good see-through with little obstruction is realized.

Further, in the door advancement side region (region indicated by symbol B in FIG. 1) of the door bag body 10, in addition to the timing belt 45, the square pipe 30, the linear guide rail 31, the slide bearing is provided in the door storage space 10 a. Units 32 and 32 are located.
Here, as shown in FIGS. 1 and 4, the linear guide rail 31 and the slide bearing unit 32 (the two members 31 and 32 constitute a slide mechanism) and the timing belt 45 are connected to the slide mechanisms 31 and 32, respectively. The timing belts 45 are disposed on the upper end side of the door pocket body 10 while being adjacent to each other.
Accordingly, since the slide mechanism 31 and 32 and the timing belt 45 are arranged together on the upper side, the above-described region B has a good see-through with almost nothing blocking the view from the center side to the lower side. Is realized.

As described above, good see-through has been achieved in both areas A and B. Therefore, it can be said that good see-through has been achieved even when the door pocket body 10 is viewed as a whole.
Here, in such a platform gate 1x, the door is normally closed, and it is generally opened only when the vehicle arrives and the passenger changes between the platform and the vehicle. That is, most passengers waiting for arrival of vehicles on the platform see the platform gate 1x with the door closed. In this regard, the platform gate 1x of the present embodiment, as described above, provides a good see-through in the portion of the door bag body 10 in a state where the door is closed, and thus gives a psychological pressure to passengers on the platform. Is made less.

  The slide mechanism (that is, the linear guide rail 31 and the slide bearing units 32 and 32) and the timing belt 45 may be disposed adjacent to each other on the lower end side of the door pocket body 10. In this case, from the center side to the upper side of the region B, a good see-through with almost nothing blocking the view is realized, and the platform gate 1x that does not give a feeling of psychological pressure to passengers on the platform can be obtained.

Further, the slide mechanisms 31 and 32 and the timing belt 45 may be arranged such that one is disposed on the upper end side of the door bag body 10 and the other is disposed on the lower end side of the door bag body 10 while being separated from each other. . In this case, in the wide space on the center side of the region B, a good see-through with almost nothing blocking the view is realized, and the platform gate 1x that does not give a feeling of psychological pressure to passengers on the platform can be obtained .

Having described the implementation mode of the present invention on the following, the technical scope of the present invention is not limited to the configuration of the above embodiments, without departing from the scope of the present invention, various modifications can be made It is.

For example, in the above you facilities embodiment has been adopted a timing belt 45 as the belt-driven body, without being limited thereto, for example, a wire, it is also possible to use rope, a belt-driven member such as a chain . However, the use of the timing belt 45 has an advantage that a reliable opening / closing operation can be performed because no slippage occurs at all unlike a simple wire or rope transmission.
