[0002]

2. Description of the Related Art As is well known, the structure of a magnetic levitation vehicle (a magnetic levitation linear ultra-high-speed train) which is currently being trialled today and its running facilities are significantly different from those related to ordinary railway vehicles. The main differences are as follows. That is, as shown in FIGS. 10 and 11, the traveling speed is, for example, 100 km /
h, the traveling wheels 2, 2 which move up and down depending on whether or not it is not less than h are mounted on both sides of the superconducting coils 3, 2.
3 are mounted, and guide wheels 5 and 5 are mounted on both sides of the floor 1 of the vehicle 1 directly above and below the floor 4 so as to move in and out of the vehicle width direction.
Guide rails 6, 6 are provided on both sides of the lower part of the vehicle 1 along the traveling route at a predetermined distance from the vehicle side wall. The guide rails 6 have traveling coils 7 and floating coils 8, respectively. Is attached. When the vehicle 1 has a low speed immediately before stopping, the traveling wheels 2, 2 abut on the rail surface 9 to roll, and the guide wheels 5, 5, the upper ends of the guide rails 6, 6, It rolls in contact with the inner surface of the vehicle, whereby the displacement of the vehicle 1 in the vehicle width direction when the vehicle is stopped is corrected. Note that reference numeral 10 in the figure denotes a passage opening that leads from the vehicle 1 to another adjacent vehicle.

The superconducting coil 3 mounted on the magnetic levitation vehicle 1 is always in an excited state and emits high magnetism of tens of thousands of gauss.
A strong magnetism is given to the passengers waiting on the platform 11 when the vehicle stops. In view of this, the present applicant has proposed in the earlier patent application (Japanese Patent Application No. 3-122488) that the following means are adopted in order to reduce the magnetic strength for passengers. That is, as shown in FIG. 12, a protective wall 12 is installed at a predetermined distance from the side edge 11a of the platform 11 near the center thereof, and the side opposite to the side edge 11a of the protective wall 12 is a magnetic shielding space. A waiting place 12a and the protective wall corresponding to the getting on / off position X of the vehicle 1
A home door 13 is provided on the home door 12, and a passage device 14 is provided which can be extended and contracted from a peripheral portion of the home door 13 toward the getting on / off position X. Details of the passage device 14 include a plurality of wall members 15... 15 made of a magnetic shielding material for shielding both sides of passengers.
Between the vehicle 1 and the vehicle 1 until the vehicle 1 is stopped and the vehicle can be entered and exited, the wall materials 15... 15 are retracted to be in the retracted state, and the home door 13 is kept in the closed state to allow entry and exit. At this point, the wall members 15... 15 are extended to form a guide path 16 for magnetic shielding, and the home door 13 is opened. Therefore, passengers can maintain a state of being shielded from magnetism by moving along the guide path 16 from the waiting place 12a to the entrance door 1a of the vehicle 1. in this case,
The expansion and contraction operation of the passage device 14 is performed by a drive cylinder 17 which is fixed to a wall material 15 at the end of the protection wall which is fixedly disposed, and as shown in FIG. The piston rod 17a of the wall member 15 is located at the tip end side of the wall member 15 which is closest to the getting on / off position X when the wall member 15 is extended.
Only connected to. A contact plate 15a is fixed to the wall member 15 on the distal end side, and a stopper 15 is attached to the intermediate wall member 15.
b is fixed, and as the piston rod 17a of the drive cylinder 17 protrudes, the backing plate 15a of the wall member 15 on the distal end comes into contact with the stopper 15b of the intermediate wall member 15, and When the wall material 15 reaches the stroke end, the two wall materials 15, 15 start cooperating. Also, when a plurality of intermediate wall members 15 are provided, each time the preceding intermediate wall member reaches the stroke end as the piston rod 17a protrudes, the backing plate of the preceding wall member is moved to the next wall member. The linking operation is started by abutting on the stopper, and the start of such a linking operation is intermittently performed a plurality of times.

[0004]

However, in the above-described passage device 14, the following wall member 15 starts to cooperate when the preceding moving wall member 15 reaches the stroke end. At the start of this coordination, not only does the smooth operation occur due to the abutment of the abutment plate 15a and the stopper 15b, but also an impulsive sound is generated, which causes noise and discomfort to passengers. There is a problem of giving. In addition, due to this, each part of the passage device 14 is damaged and durability is reduced. Such a problem can occur not only when the passage device 14 is extended but also when it is retracted.

The present invention has been made in view of the above circumstances, and enables the expansion and contraction operation of a passage device composed of a plurality of wall materials to be performed smoothly without accompanying an impact sound or the like. It is an object of the present invention to prevent a decrease in durability of the device and to prevent generation of noise.

[0006]

According to the present invention, a platform for a magnetic levitation vehicle according to the present invention is configured as follows in order to achieve the above technical object.
That is, a protective wall installed at a predetermined distance closer to the center from the side edge of the platform, and a boarding opening formed in the protective wall corresponding to the position at which the magnetic levitation vehicle gets on and off,
A boarding / alighting device provided with a passage device which is arranged from the boarding / opening opening toward the direction of the boarding / alighting position and shields at least a side of the passenger to form a guide passage, and which is extendable / contractible with respect to the passage direction; The passage device includes a plurality of wall members made of a magnetic shielding material incorporated in a nested shape so as to be able to move back and forth between the plurality of wall members, and a tip side wall member which is present at the end of the plurality of wall members at the side of the getting on / off position when extended. And a synchronous drive means for moving the respective wall members in and out of synchronization with each other, and a synchronous drive means for moving the respective wall materials in and out of the protective wall. It has a lever spanning the side surface of the opening side wall material and the side surface of the tip side wall material located at the end of the opening / closing opening side, and one end of the lever has one of the two wall materials. It is rotatably connected to the side The end is movably connected to the other side in the vertical direction, and an intermediate portion of the lever is movably connected in the vertical direction to the side of the intermediate wall material located between the two wall materials. And a drive cylinder for rotating the lever about the rotatable connecting portion as a fulcrum.

[0007]

According to the above-mentioned means, when the magnetic levitation vehicle stops at a predetermined position on the platform, a plurality of wall members made of nested magnetic shielding members in the passage device are formed by the operation of the synchronous drive means. By protruding relative to each other between the wall materials, it extends as a whole toward the entrance / exit position side of the vehicle, and the buffer provided on the tip side wall material abuts around the entrance / exit door of the vehicle side wall. A guide passage is formed as a magnetically shielded space from the opening of the protective wall to the entrance door of the vehicle side wall. More specifically, the drive cylinder of the synchronous drive means rotates the lever about the rotatable connecting portion, so that all the wall materials of the front end side wall material, the intermediate wall material, and the opening side wall material are simultaneously at the boarding position. , The drive cylinder stops when the buffer portion of the tip side wall material comes into contact with the vehicle side wall, and the above-described guide passage is formed.

In this case, when each of the wall members is in the retracted state, the lever is inclined (for example, slightly inclined from a vertical line) so that the horizontal dimension between the connecting portions of the lever to each wall member is reduced. If the lever is rotated from such a state, the inclination angle between the lever and the vertical line becomes large, and accordingly, the distance between the connecting portions of the lever to each wall member is increased. Is increased in the horizontal direction, and each wall member moves synchronously. During this movement, the lever pivots about the connecting portion for either the tip side wall material or the opening side wall material as a fulcrum, and the connecting portion of the lever for the other moves upward or downward, and in the middle of the lever. The connection of the section to the intermediate wall material also moves upward or downward. This allows
This enables smooth synchronous movement of each wall material. In this way, after each wall material moves synchronously to form a guide passage, the entrance door of the vehicle is opened and passengers get on and off between the guide passage and the cabin in the vehicle, When this getting on and off is completed, the drive cylinder is operated again to rotate the lever in the opposite direction to the above, so that the horizontal dimension between the connecting portions of the lever to each wall material is shortened, and as a result, Then, the respective wall materials shrink and retreat toward the protection wall in synchronization with each other, and finally enter the retracted state.

Projecting plate members 31, 31 are fixed to the front portion of the door bag body 26 fixed to 30 and the front portion of the cubicle 29 on the other side. A cushioning member that abuts on the side wall around the entrance / exit door 1a of the vehicle 1 over the tip of the sill 30
32 is installed. The lower portion of the cushioning member 32 is curved in the same shape as the curved portion 1x of the vehicle 1 as shown in FIG. Also, as shown in FIG.
The left part of the upper guide rail 34 that suspends and supports 27
(The side of the protective wall)
When the door 27 is opened, the door 27 is inclined, so that the door 27 can be closed even in the narrow space of the tip side wall 21d.
Consideration is given so that a sufficient opening width can be ensured when the device is fully opened. In addition, in the glass portions 27a, 26a of the door body 27 and the door bag body 26 (see FIG. 1), an iron-based net is buried for magnetic shielding, and the protective wall is provided.
No home door or the like is installed in the 12 openings 12a (see FIG. 8).

Next, the operation of the above embodiment will be described. When the vehicle 1 is not stopped, the piston rod 43x of the drive cylinder 43 retreats, and as shown in FIG.
The horizontal space between the first and second a, 42b becomes shorter, and the first and second intermediate wall members 21b, 21c and the tip side wall member 21d are stored inside the opening side wall member 21a. ,
The operation of the motor 62 brings the guide rail movable portion 6a into an upright state. After that, when the vehicle 1 enters the platform 11 and stops, the piston rod 43x of the drive cylinder 43

It contacts the vehicle side wall around 1a. When the wall members 21b, 21c, and 21d protrude, as the horizontal distance between the pair of levers 42a, 42b becomes longer, the slide body 45y at the lower end of one lever 42a and the other lever 42b The slide body 47y at the lower end is provided with the long hole 46 and the opening side wall material 21 of the front end side wall material 21d.
a and gradually move upward along the long hole 48, and at the same time, the two pin-shaped slide bodies 49 and 50 at the intermediate portion of the other lever 42b are also connected to the first intermediate wall material 21b and the second intermediate wall material 21c, respectively. It gradually moves upward along the long holes 51 and 52. By performing such an operation, the levers 42a, 4
With the movement of the link 2b, all of the wall members 21b, 21c, and 21d gradually protrude while being synchronized with each other without relatively stopping. At this point, the guide rail movable portion 6a has fallen due to the operation of the motor 62.

As a result, a guide passage, which is a magnetically shielded space, is formed at a position from the entrance / exit opening 24 of the protection wall 12 to the entrance / exit door 1a of the vehicle 1. Therefore, the passengers waiting at the waiting area behind the protective wall 12 enter the guideway, and when the door 1a of the vehicle 1 is opened, the vehicle 1
Passengers get off the cabin from inside the cabin and the passengers get on the cabin inside the vehicle 1. At the time of getting on and off, the automatic door device 25 provided on the tip side wall member 21d detects the presence of the passenger and automatically opens the door 27. Then, when all the passengers get on and off, the vehicle 1 departs,
Prior to this departure, the piston rod of the drive cylinder 43
As the 43x retracts, the wall members 21b, 21c, and 21d relatively contract and move synchronously with each other, and retract as a whole toward the protection wall 12 side. In this case, since the door body 27 of the automatic door device 25 mounted on the tip side wall member 21d is in a fully closed state, passengers remaining in the guidance passage can move the closed end side wall material 21d. With the protective wall 12
, And is not left behind in the magnet generating space outside the guide passage. When the wall members 21b, 21c, and 21d are completely retracted into the retracted state as shown in FIG. 9, all passengers in the guideway move to the magnetic shielding space behind the protective wall 12. Thereafter, when the vehicle 1 departs and the subsequent vehicle enters the platform 11 and stops again,
The same operation as described above is repeatedly performed.

In the above-described embodiment, the synchronous drive means 23 uses a pair of levers 42a, 42b cross-coupled. For example, the one corresponding to one lever 42a is eliminated. Thus, the piston rod 43x of the drive cylinder 43 may be connected to the one corresponding to the other lever 42b, and when a single lever is used in this way, the lever is not inclined but is horizontally inclined. You may make it arrange | position in a shape.

[0017]

As described above, according to the platform device for a magnetically levitated vehicle according to the present invention, when the vehicle is stopped, it is nested and formed so as to form a guide path for passengers to be able to move in and out of each other. Of the plurality of wall materials, one end of a lever is rotatably connected to one of the side walls of the tip side wall material and the opening side wall material at both ends, and the other side surface is provided with another lever. The end is vertically movably connected, and the middle portion of the lever is further vertically movably connected to the side wall of the intermediate wall member, and the lever is rotated by the operation of the drive cylinder about the rotatable connection portion as a fulcrum. As a result, the horizontal dimension between each wall member and each connecting portion of the lever changes with the rotation of the lever, whereby all the wall members continuously move back and forth in synchronization with each other. And the preceding wall material is struck as in the past. At the start of the linking operation, the occurrence of the contact shock and the impact sound at the start of the linking operation caused by the start of the linking operation at the time of reaching the It is possible to move in and out, so that problems such as damage to the passage device and discomfort to passengers can be solved.
