  When a device for automating train operation or supporting operation such as ATO (automatic train operation device) or TASC (fixed position stop device) is introduced together with the platform door device, the accuracy of the stop position of the train is good. . Therefore, it is hard to produce position shift between the stop position of a train, and the installation position of a platform door apparatus.

  On the other hand, when the platform door device is operated without using ATO or TASC, the variation in the stop position of the train increases. However, in order to reduce the amount of capital investment, it is considered that introducing a platform door device without using ATO or TASC is one of the effective options. In this case, it is necessary to design and manufacture the platform door device in consideration of the displacement of the stop position of the train.

  Moreover, when using ATO or TASC, it can instruct | indicate opening and closing of the door part of a platform door apparatus from a driver's cab. However, when the platform door device is operated without using ATO or TASC, signal transmission / reception does not exist in the first place, so it is necessary to adopt other means. As another means, a method in which the conductor directly opens and closes the door portion of the platform door device can be considered.

  The present invention has been made in view of such circumstances, and a platform door that can smoothly open and close the door portion of the platform door device by the conductor even when the position of the stop position of the train is displaced. An object is to provide an apparatus.

In order to solve the above problems, the platform door device of the present invention employs the following means.
That is, the platform door device according to the present invention is provided substantially parallel to the traveling direction of the train at a position corresponding to the opening of the crew door of the train when the train stops on the platform. A rod-shaped lever that is movable in a direction substantially perpendicular to the direction, the position of the lever substantially perpendicular to the axial direction of the lever corresponds to the opening / closing operation of the door portion of the platform door device, and the shaft of the lever The length corresponds to the allowable range of the stop position of the train.

  According to the present invention, in the platform door device, the rod-shaped lever is provided at a position corresponding to the train crew door when the train stops, and is installed substantially parallel to the traveling direction of the train. The lever is movable in a direction substantially perpendicular to the axial direction, that is, in a vertical direction when the platform door device is installed, and the door portion of the platform door device is opened and closed by the movement of the lever. In addition, since the axial length of the lever corresponds to the allowable range of the stop position of the train, even if the train does not always stop at the same position and moves back and forth, the crew member must move the lever within the reach of the hand. Can be operated.

  In addition, because the crew opens and closes the door by operating the lever with force applied to the lever, malfunctions due to external disturbances are compared to when opening and closing the door by detecting and blocking the optical axis. Is unlikely to occur.

  In the above invention, the correspondence relationship between the position in the direction substantially perpendicular to the axial center direction of the lever and the opening / closing operation of the door portion of the platform door device is based on the position of the crew switch for the train It is desirable to match the correspondence with the opening / closing operation of the door.

  According to this invention, since the operation of the switch for the crew member when the crew member opens and closes the door part of the entrance / exit of the train and the operation of the lever when the door part of the platform door device is opened and closed coincide, And malfunction can be prevented.

  In the said invention, it is desirable that the opening width of the opening part which the said door part opens and closes is wider than the entrance / exit of the said train.

  According to this invention, the opening width of the opening that opens and closes the door is wider than the entrance of the train, so even if the train does not always stop at the same position, the range in which the train can stop before and after is widened. Can do. Even in this case, by increasing the axial length of the lever, the crew can operate the lever within the reach of the hand. Moreover, if the axial length of the lever is long, the range in which the train can stop before and after can be widened without narrowing the allowable range of the stop position of the train in consideration of the operation of the crew.

  According to this invention, since the axial length of the lever provided substantially parallel to the traveling direction of the train corresponds to the allowable range of the stop position of the train, the train does not always stop at the same position, In this case, that is, even when the position of the stop position of the train is shifted, the door of the platform door device can be smoothly opened and closed by the conductor.

It is a front view which shows the opening / closing lever of the platform door apparatus which concerns on the same embodiment. It is explanatory drawing which shows the use condition of the platform door apparatus which concerns on the embodiment. It is the longitudinal cross-sectional view cut | disconnected by the AA line of FIG.

Embodiments according to the present invention will be described below with reference to the drawings.
The platform door device 1 is a waist-high type and has a height of about 1.3 m to 1.4 m from the installation surface on the platform 6 to the top plate. The platform door device 1 includes door pocket portions 2 and 3 and a door portion 4. The door portion 4 enters and exits from the side surface of the door pocket portion 2. A series of platform door devices 1 are configured by installing the plurality of door pockets 2 and 3 and the door 4 along the edge of the platform 6 in accordance with the length of the train 10. In addition, as shown in FIG.1 and FIG.2, the fixed fence 5 may be provided in the edge part of the platform 6. FIG. The fixed fence 5 is installed in a place where the train 10 is not located even when the train 10 stops and is not related to getting on and off.

  The door 4 is plate-shaped and moves in the in-plane direction to open and close the opening of the platform door device 1. The length L1 of the opening is longer than the length L2 of the entrance / exit in the door 11 of the train 10, as shown in FIG. Therefore, as shown in FIG. 2, even when the train 10 does not always stop at the same position, the range in which the train 10 can stop before and after can be widened. The interval between two adjacent openings is determined in consideration of the interval between the entrances and exits of the train 10 that stops on the platform 6, the length L2 of the entrance and exit, the number of entrances and exits, and the like.

  The door pockets 2 and 3 are guides and slide rails for movably supporting the door 4, driving units such as a motor for driving the door 4, a transmission mechanism such as a rack and pinion or belt, and driving of the door 4. A control panel to be controlled is housed inside.

  The door pocket portion 2 is provided at a position corresponding to an intermediate portion of the train 10 when the train 10 stops on the platform 6. Inside the door pocket portion 2, two door portions 4 are accommodated in a direction perpendicular to the in-plane direction of the door portion 4. Thereby, the length of the door pocket part 2 can be shortened compared with the case where the two door parts 4 are not accommodated in the inside of the door pocket part 2 overlappingly.

  On the other hand, the door pocket portion 3 is provided at a position corresponding to the head portion or the tail portion of the train 10 when the train 10 stops on the platform 6. The door pocket portion 3 accommodates one door portion 4. Moreover, as shown in FIGS. 3 to 5, the door pocket 3 is provided with an opening / closing lever 7 on the stop side of the train 10, that is, on the track side. FIG. 4 shows a situation where the crew member is using the opening / closing lever 7.

  The opening / closing lever 7 is installed in the door pocket 3 at a position corresponding to the opening of the crew door 12 of the train 10 when the train 10 stops. The opening / closing lever 7 is a rod-shaped member and is installed substantially parallel to the traveling direction of the train 10. The axial length of the opening / closing lever 7 corresponds to the allowable range of the stop position of the train 10. The allowable range of the stop position of the train 10 is determined by the relationship between the length L1 of the opening of the platform door device 1 and the length L2 of the entrance / exit of the train 10.

  When the train 10 is stopped within the allowable range of the stop position, the range of the traveling direction of the train 10 of the opening / closing lever 7 is considered in consideration of the reach of the crew standing at the opening of the crew door 12. The axis length is determined. For example, when the platform door device 1 is operated without using ATO or TASC, the variation in the stop position of the train 10 increases. In this way, even when the train 10 does not always stop at the same position and moves back and forth, by increasing the axial length of the opening / closing lever 7, the crew can stay within the reach of the train 10 while staying on the train 10. The open / close lever 7 can be operated. Moreover, if the axial length of the opening / closing lever 7 is long, the range in which the train 10 can stop before and after can be set wide without narrowing the allowable range of the stop position of the train 10 in consideration of the operation of the crew.

  The opening / closing lever 7 is accommodated in a recess 8 formed in the door pocket 3. Thereby, it can prevent that the opening / closing lever 7 protrudes to the track side, and can install the opening / closing lever 7 in the door pocket part 3 so that a building limit may not be exceeded. In addition, a collar portion 9 may be installed above the opening / closing lever 7 in parallel to the opening / closing lever 7.

  For example, as shown in FIG. 5, the opening / closing lever 7 is rotatable about a fulcrum 15. Accordingly, the opening / closing lever 7 is movable in a direction substantially perpendicular to the axial center direction of the opening / closing lever 7, that is, in the vertical direction when the platform door device 1 is installed. In addition, as long as the opening / closing lever 7 can move in a direction substantially perpendicular to the axial direction of the opening / closing lever 7, the opening / closing lever 7 may be movable by another structure.

  The vertical position of the opening / closing lever 7 is associated with the opening / closing operation of the door portion 4 of the platform door device 1. For example, the door 4 is opened by raising the open / close lever 7 from the bottom to the top, and the door 4 is closed by lowering the open / close lever 7 from the top to the bottom.

  Further, the correspondence between the vertical position of the opening / closing lever 7 and the opening / closing operation of the door portion 4 of the platform door device 1 corresponds to the correspondence between the position of the crew switch (conductor switch) of the train 10 and the opening / closing operation of the door 11 of the train 10. Consistent with the relationship. For example, when the door 11 of the train 10 is opened, the button below the crew switch is pushed from above to below, and when closing, the button above is pushed down from top to bottom. This corresponds to the operation method of the opening / closing lever 7. The relationship between the vertical relationship and the opening / closing operation may be opposite to that in the above example.

  In this manner, by making the operation for opening and closing the door portion 4 of the platform door device 1 coincide with the operation for opening and closing the door 11 of the train 10, it is possible to prevent erroneous operations and malfunctions. Moreover, in this embodiment, when the crew member applies force with respect to the opening / closing lever 7 and operates the opening / closing lever 7, the door part 4 opens and closes. Therefore, compared with the case where opening / closing of the door part 4 is operated by detecting / blocking the optical axis, the present embodiment is less likely to cause malfunction due to disturbance. For example, when the optical axis is used, a malfunction may occur when an insect, a leaf, or the like enters the optical axis instead of a crew member's hand, but in this embodiment, the opening / closing lever 7 is reliably moved. Because it is detected, it is not easily affected by disturbance.

  As mentioned above, according to this embodiment, since the axial length of the opening / closing lever 7 provided substantially parallel to the traveling direction of the train 10 corresponds to the allowable range of the stop position of the train 10, the train 10 is always Even when the vehicle 10 moves back and forth without stopping at the same position, that is, when the position of the stop position of the train 10 is shifted, the door 4 of the platform door device 1 can be smoothly opened and closed by the conductor.

  In particular, in the present embodiment, when the platform door device 1 is operated without using ATO, TASC, etc., since signal transmission / reception does not exist in the first place, the opening / closing of the door portion 4 of the platform door device 1 from the driver's cab is performed. This is effective when the conductor directly opens and closes the door portion 4 of the platform door device 1. And since the platform door apparatus 1 can be operated without introducing ATO, TASC, etc., introduction of the platform door apparatus 1 with reduced capital investment can be realized.
