  However, in the case where the crew door panel 91 is provided at a position that does not interfere with the passenger door panel 93, the problem is that it is impossible to deal with a vehicle in which the distance between the crew door 92 on which the crew gets on and off and the passenger door 94 on which the passenger gets on and off is short. There is. Moreover, for example, even if the partition panel 96 is configured to be pivotable as an emergency escape door as in Patent Document 1, when the passenger door panel 93 is opened as shown in FIG. Since the door panel 93 for advancing will advance, this partition panel 96 cannot be comprised as a crew door panel. Accordingly, the crew door panel 91 needs to be disposed away from the position of the partition panel 96, so that it cannot cope with a train in which the passenger door 94 and the crew door 92 are narrowly spaced. This problem also applies to the case where the guide box 95 is configured to be larger than the width of the passenger door panel 93 and the passenger door panel 93 is housed in the guide box 95. In this case, The door panel 91 needs to be disposed at a position deviated from the position of the guide box 95, and cannot be adapted to the train.

  Therefore, the present invention has been made in view of such a point, and an object of the present invention is to provide a platform door device that can cope with a train having a narrow interval between a passenger door and a crew door.

In order to achieve the above object, the present invention provides a home door device including a guide box configured to be installed on a platform and a door panel supported by the guide box so as to be capable of opening and closing. comprising a rotary support for rotatably supported with respect to the platform, and a home position detecting means capable of detecting the origin position of the rotating support moving direction is the direction along the platform edge of the door panel, the origin opening and closing operation of the door panel on the condition that the rotary support by the position detecting means is detected to be at the origin position are permitted.

  In the present invention, since the guide box itself is rotatable, the door panel can be rotated together with the guide box with respect to the platform. Therefore, even if a vehicle with a short distance between the passenger door and the crew door enters the platform, if the guide box is rotated, the guide box and the door panel will not get in the way, and the crew will be able to pass smoothly. Can do. In other words, in the platform door device according to the present invention, the guide box can be used as a crew door panel for opening the crew passage. For this reason, it is possible to avoid a situation in which the position of the crew door panel is restricted, and it can be installed on a platform where a vehicle with a short distance between the passenger door and the crew door enters.

And when the moving direction of the door panel deviates from the direction along the platform edge, it is possible to prevent the door panel from opening and closing while the door panel is not in the normal direction. Can be secured.

In the present invention , the rotation support is configured to be lockable at the origin position, and has a lock control means for releasing the lock of the rotation support based on a command output in response to an operation by a crew member. Is preferred.

  In this aspect, since the unlocking of the guide box is performed based on a command that is output according to the operation of the crew, it is possible to avoid the situation where the guide box is unlocked without depending on the crew's intention, Safety on the platform can be ensured.

  Furthermore, it has an open position detection means capable of detecting that the door panel is in the open position, and the lock control means is provided on the condition that the door position is detected by the open position detection means. Preferably, the rotation support is unlocked based on the command.

  In this aspect, it is possible to avoid the situation where the guide box is unlocked without depending on the crew member's intention, but when the door panel is not in the open position even when the lock is released according to the crew member's intention. The guide box is maintained in a locked state. That is, when the door panel is advanced from the guide box and is in the closed position where the passenger passage is closed, unlocking of the guide box is restricted. Thereby, even when the lock is released based on the intention of the crew member, it is possible to prevent the guide box from rotating in a state where safety is not ensured.

  Furthermore, it is preferable to have return control means for returning the rotary support to the origin position.

  In this aspect, when the guide box is not in the direction along the platform edge and the rotation support is not at the origin position, the rotation support body is returned to the origin position by the return control means. For example, the crew member returns the guide box to the origin position. For example, in the case where the rotation support is forgotten, it is possible to prevent the rotation support body from being maintained in a state shifted from the origin position. This can prevent the safety of the passengers on the platform from being compromised.

  As described above, according to the present invention, it is possible to deal with a train having a narrow interval between the passenger door and the crew door.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a front view of a platform door device 10 according to an embodiment of the present invention as viewed from the platform side toward the track side. The platform door device 10 is installed at a position where the head of the train stops, and is configured to be able to open and close the crew passage 28 for getting on and off the train cab.

  As shown in FIG. 1, the platform door device 10 includes a pair of guide boxes 12 and 13 disposed at a predetermined interval along the track-side end of the platform P, and penetrates the guide boxes 12 and 13. And a pair of sliding door type door panels 16 and 17 arranged in the above state.

  Each of the guide boxes 12 and 13 is formed in a vertically long and vertically long shape, and has a cylindrical shape through which the door panels 16 and 17 can penetrate in a direction along the track (left and right direction in FIG. 1). The width of the guide boxes 12 and 13 in the direction along the track is shorter than the width of the door panels 16 and 17.

  A space between the guide boxes 12 and 13 is formed as a boarding / alighting passage 20 for passengers to get on and off the vehicle. The door panels 16 and 17 reciprocate in the direction along the track between an open position that opens the entrance / exit passage 20 and a close position that closes the entrance / exit passage 20. In the open position, the door tips 16a and 17a of the door panels 16 and 17 are positioned in the vicinity of the passage side end portions (one end portions) of the guide boxes 12 and 13, and the door bottoms 16b and 17b of the door panels 16 and 17 are the guide box 12 and It protrudes from 13 partition panel side edge parts (other end part). On the other hand, in the closed position, the door tips 16a and 17a of the door panels 16 and 17 protrude outward from the passage side end portions of the guide boxes 12 and 13, and the door bottoms 16b and 17b of the door panels 16 and 17 are guided by the guide boxes 12 and 13 respectively. Get inside.

  A guide box (first guide box) 12 disposed on the right side of FIG. 1 is fixed to the platform P. A partition panel 18 made of a rectangular panel is fixed to the right side of the guide box 12.

The partition panel 19 is formed in a size that can cover the door panel 17 in the closed position.

  As shown in FIG. 2, the partition panels 18 and 19 are fixed to the end portions on the home side in the guide boxes 12 and 13, respectively. The partition panels 18 and 19 are disposed at the end on the home side because the door panels 16 and 17 are inserted through the raceway side portions of the guide boxes 12 and 13. , 17 so as not to interfere with each other.

  The second guide box 13 is rotatably supported with respect to the platform P by a rotation support 24 (see FIG. 3). The second guide box 13 can take a basic posture along the edge of the platform P and a rotating posture that is substantially orthogonal to the edge of the platform P on the track side. When the second guide box 13 is in the basic position, the crew member passage 28 is closed by the second guide box 13, the partition panel 19, and the adjacent panel 26, and when the second guide box 13 is in the turning position, the crew member passage 28 is closed. Is released. And since the partition panel 19 is being fixed to the 2nd guide box 13, when the 2nd guide box 13 rotates, this partition panel 19 will rotate together, maintaining both positional relationship. That is, since the partition panel 19 is adjacent to the second guide box 13, when a train with a narrow space between the crew door 21a and the passenger door 21b of the vehicle 21 enters, the partition panel 19 comes close to the crew door 21a. It will be. Moreover, since the partition panel 19 is sized to cover the door panel 17 in the open position, the crew member who gets on and off the train cab by rotating the partition panel 19 together with the second guide box 13. You can avoid becoming an obstacle. The adjacent panel 26 is fixed to the platform P.

  In addition, the platform P is partitioned into a track side and a home side inside thereof by connecting a number of other types of home door devices with a partition panel (not shown) interposed therebetween. In another form of the platform door device, the left guide box and the right guide box are fixed. And the platform door apparatus comprised so that one guide box (right side guide box) can rotate similarly to the platform door apparatus 10 which concerns on this embodiment in the position corresponding to the tail end of a train. It will be.

  As shown schematically in FIG. 3, the rotary support 24 is configured to be fixed to the end of the platform P on the track side. This will be specifically described. A recess 30 is formed in the lower portion of the end portion on the track side of the platform P, and the end portion on the track side has a shape protruding toward the track side from the lower portion. A pit 31 is formed on the upper surface (floor surface) of the track-side end portion, and a through-hole 32 is formed in the track-side end portion so that the upper end portion opens at the bottom surface of the pit 31. The through hole 32 vertically penetrates the end portion on the track side, and the lower end thereof is opened in the recess 30.

  The rotating support 24 includes a fixed portion 35 fixed to the platform P and a movable portion 36 configured to be rotatable with respect to the fixed portion 35. The fixing portion 35 includes an upper fixing portion 35a disposed in the pit 31 above the track-side end portion of the platform P and a lower fixing portion 35b disposed below the track-side end portion. The upper fixing portion 35 a receives the load of the second guide box 13. A driving unit 38 for driving the movable portion 36 is provided in the lower fixed portion 35b.

  The movable portion 36 includes a top plate 36a disposed in the pit 31 so as to match the floor surface of the platform P, a shaft portion 36b fixed to the lower surface of the top plate 36a and inserted through the through hole 32, and the shaft. The motor 36c (refer FIG. 5) for rotating the part 36b is provided. A bearing 41 is interposed between the top plate 36a and the upper fixing portion 35a, and the second guide box 13 is fixed to the upper surface of the top plate 36a. The motor 36c is disposed in the drive unit 38 of the lower fixed portion 35b, and the shaft portion 36b and the top plate 36a are rotated by driving the motor 36c. The drive unit 38 is provided with a lock means 43 (see FIG. 5) for preventing the shaft portion 36b from rotating.

  As shown in FIG. 4, the home door device 10 includes an origin position proximity sensor 46, a rotational position proximity sensor 47, and a position detection dog 49. The origin position proximity sensor 46 constitutes origin position detection means for detecting that the rotation support 24 is at the origin position, and the rotation position proximity sensor 47 is at a position where the rotation support 24 is rotated from the origin position. The rotational position detecting means for detecting this is configured. These proximity sensors 46 and 47 are fixed to the lower fixing portion 35b. The position detection dog 49 is fixed to the shaft portion 36b and rotates integrally with the shaft portion 36b. The proximity sensors 46 and 47 output a detection signal when the position detection dog 49 comes within a predetermined area. The shaft portion 36b is used as a wiring route for the proximity sensors 46 and 47 and the like.

  Here, the origin position of the rotating support 24 means a position where the second guide box 13 is in a basic posture state indicated by a solid line in FIG. That is, when the rotary support 24 is at the origin position, the door panel 17 is in a direction along the edge of the platform P. The positional relationship between the origin position proximity sensor 46 and the position detection dog 49 is defined so that a detection signal is output from the origin position proximity sensor 46 when the door panel 17 is in an attitude along the edge of the platform P. ing.

  On the other hand, the rotational position proximity sensor 47 detects that the door panel 17 is in a direction intersecting with the track side edge of the platform P, for example. When the door panel 17 rotates, the pole 51 (see FIG. 2) erected on the platform P functions as a stopper. The positional relationship between the rotational position proximity sensor 47 and the position detection dog 49 is defined so that a detection signal is output from the rotational position proximity sensor 47 when the door panel 17 is at the stop position.

  As shown in FIG. 5, the controller 55 of the home door apparatus 10 includes a door panel control unit (APG control unit) 56 and a rotation support body control unit (FDP control unit 57). The APG control unit 56 is a control unit for performing opening / closing control of at least the door panels 16, 17. The control unit 56 includes a signal from the open position proximity sensor 59, a signal from the closed position proximity sensor 60, and A release command (FDP lock release command) for unlocking the rotary support 24 and an APG door open / close command for opening and closing the door panels 16 and 17 are input. The FDP lock release command is a command output from the train based on the operation of the crew in the train, and is used when the crew gets off the train and opens the crew passage 28. For example, a command device is provided in a cab or the like, and an FDP lock release command is output when a crew member operates the command device. The APG door opening / closing command is a command that is output from a central control panel (not shown) in response to train entry.

  The open position proximity sensor 59 constitutes an open position detecting means for detecting that the door panels 16 and 17 are in the open position, and outputs a detection signal when the door panels 16 and 17 are in the open position. The closed position proximity sensor 60 constitutes closed position detecting means for detecting that the door panels 16 and 17 are in the closed position, and outputs a detection signal when the door panels 16 and 17 are in the closed position. The APG control unit 56 outputs a control signal for opening and closing the door panels 16 and 17, a control signal for locking the door panels 16 and 17, and an FDP lock release signal.

  The APG control unit 56 includes, for example, a CPU, a ROM, a RAM, and the like, and performs a control operation by reading and executing a control program stored in the ROM. The functions of the APG control unit 56 include an opening / closing control means 56a and an opening restriction control means 56b.

  The opening / closing control means 56a is for performing opening / closing control of the door panels 16, 17. That is, the opening / closing control means 56a outputs a control signal for opening / closing the door panels 16 and 17 when an APG door opening / closing command transmitted from a central control panel or the like (not shown) is input. If this control signal is a signal for opening the door panels 16 and 17, the electric lock 62 unlocks the door panels 16 and 17, and the drive motor 64 drives the door panels 16 and 17 to open.

  The opening restriction control means 56b restricts a control signal for opening the door panels 16 and 17 from being outputted from the opening / closing control means 56a when a later-described origin position signal outputted from the FDP control unit 57 is inputted. . Thereby, the unlocking of the electric lock 62 is restricted, and the door panels 16 and 17 can be maintained so that they cannot be opened.

  On the other hand, the FDP control unit 57 is a control unit for performing at least lock control of the rotation support 24. The control unit 57 includes a signal from the origin position proximity sensor 46 and a signal from the rotation position proximity sensor 47. A signal and a signal from the lock unit 43 are input. Then, the FDP control unit 57 outputs an origin position signal, a rotation drive signal, and a lock signal. The origin position signal is input to the APG control unit 56 as described above.

  The functions of the FDP control unit 57 include a lock control means 57a and a return control means 57b. The lock control means 57a is for performing control for releasing the lock of the rotary support 24. The lock means 43 of the drive unit 38 keeps the movable part 36 in the normal lock state. When the FDP unlock signal output from the APG control unit 56 is input, the lock control unit 57 a unlocks the movable portion 36 by the lock unit 43. At this time, the APG control unit 56 that has received the FDP lock release command output from the train command device outputs an FDP lock release signal on condition that the door panels 16 and 17 are in the open position. The lock control means 57a releases the lock on the condition that the door panels 16 and 17 are detected to be in the open position.

  The return control means 57b drives the motor 36c of the drive unit 38 to return the rotation support 24 to the origin position when the rotation support 24 is maintained at the rotation position for a predetermined time or more.

  Next, operation | movement of the platform door apparatus 10 which concerns on this embodiment is demonstrated, referring the flowchart of FIG.6 and FIG.7.

  First, in a normal time when the train is not connected, the second guide box 13 is in a basic posture, and in this state, the door panel 17 is in the closed position, and the boarding passage 20 and the crew passage 28 are closed. Since the rotation support 24 is locked, the second guide box 13 cannot be rotated. Thereby, the passenger on the platform P cannot go to the track side, and the safety of the passenger is ensured.

  When the train enters, the APG door opening command transmitted from the central control panel or the like is input to the APG control unit 56 (step ST1), and it is confirmed that the rotary support 24 is at the origin position (step ST2). Then, the drive motor 64 is driven. As a result, the door panels 16 and 17 move from the closed position toward the open position to open the entrance / exit passage 20 (steps ST3 and ST4). When the door panels 16 and 17 are opened, the presence / absence of an FDP lock release command is confirmed (step ST5). This FDP lock release command is a command that is output when the crew member performs a predetermined operation on the commanding device in advance when the crew member of the train opens the crew member door 21a and attempts to get down onto the platform P.

  When it is confirmed that the FDP lock release command has been issued, an FDP lock release signal is output from the APG control unit 56, and the FDP control unit 57 releases the lock of the movable portion 36 by the lock means 43 (step ST6). Thereby, the second guide box 13 can be rotated, and the crew member passage 28 can be opened when the crew member rotates the second guide box 13 by pushing the second guide box 13 or the door panel 17 from the track side (step ST7). At this time, the door panel 17 is in the open position.

  During this time, the position of the rotation support 24 is detected by the origin position proximity sensor 46 and the rotation position proximity sensor 47, and it continues to determine whether or not the rotation support 24 has returned to the origin position (step ST8). When the second guide box 13 is returned to the basic posture, the movable portion 36 of the rotary support 24 is locked again (step ST9). At this time, if the second guide box 13 is not returned from the pivoting position to the basic position within a predetermined time, that is, if the crew member forgets to close the second guide box 13, the motor 36c is driven to bring the rotation support 24 to the origin position. Return.

  When the passenger boarding / exiting is finished and an APG door close command for closing the door panels 16 and 17 is input (step ST10), the drive motor 64 is driven to close the door panels 16 and 17 (step ST11), and the closed position It is confirmed by the proximity sensor 60 whether or not the door panels 16 and 17 are in the closed position (step ST12). When this is confirmed, the train starts.

  If the FDP lock release command is not issued, the determination in step ST5 is NO, so that the movable portion 36 is locked by the lock means 43 and the second guide box 13 cannot be rotated.

  As described above, in the platform door device 10 of the present embodiment, the second guide box 13 itself is rotatable, and therefore the second guide box 13 is rotated together with the door panel 17 with respect to the platform P. Can do. For this reason, even if the vehicle 21 with a short interval between the crew door 21a and the passenger door 21b enters the platform P, the guide box 13 and the door panel 17 do not get in the way if the second guide box 13 is rotated. The crew can pass smoothly. In other words, in the present home door apparatus 10, the guide box 13 can also be used as a crew door panel for opening the crew passage 28. For this reason, it is possible to avoid a situation in which the position of the crew door panel is restricted, and it can be installed on a platform into which a vehicle with a short distance between the crew door 21a and the passenger door 21b enters.

  In the present embodiment, the door panels 16 and 17 are allowed to open on the condition that the rotation support 24 is detected to be at the origin position, so that the moving direction of the door panels 16 and 17 is a direction along the platform edge. It is possible to prevent the door panels 16 and 17 from opening when they are off. Thereby, it is possible to prevent the door panels 16 and 17 from opening while the door panels 16 and 17 are not in the normal direction, and to ensure the safety of the home door device 10.

  Moreover, in this embodiment, since the lock release of the 2nd guide box 13 is performed based on the command output according to a crew member's operation, the lock | rock of the 2nd guide box 13 is released regardless of a crew member's intention. The situation can be avoided and safety on the platform P can be ensured.

  Further, in the present embodiment, the lock of the rotation support 24 is released based on the command on the condition that the door panels 16 and 17 are detected to be in the open position. However, if the door panels 16 and 17 are not in the open position even if the lock is released by the crew, the second guide box 13 can be avoided. The guide box 13 is maintained in a locked state. That is, when the door panel 17 is advanced from the second guide box 13 and is in the closed position where the entrance / exit passage 20 is closed, unlocking of the second guide box 13 is restricted. Thereby, even if it is a case where a lock | rock is cancelled | released based on a crew member's intention, it can prevent beforehand that the 2nd guide box 13 rotates in the state where safety is not ensured.

  Further, in the present embodiment, when the second guide box 13 is not in the direction along the platform edge and the rotation support 24 is not at the origin position, the motor 36c is driven and the rotation support 24 is brought to the origin position by the return control means 57b. Since it returns, for example, when a crew member forgets to return the 2nd guide box 13, it can prevent that the rotation support body 24 is maintained in the state which shifted | deviated from the origin position. As a result, it is possible to prevent the safety of passengers on the platform P from being damaged.

  The present invention is not limited to this embodiment, and various changes and improvements can be made without departing from the spirit of the present invention. For example, in this embodiment, the width of the guide boxes 12 and 13 is shorter than the width of the door panels 16 and 17, and the door bottoms 16b and 17b of the door panels 16 and 17 project from the guide boxes 12 and 13 in the open position. However, instead of this, the door panels 16 and 17 may be configured to be completely accommodated in the guide box at the open position. In this case, the guide boxes 12 and 13 are sized so as to extend, for example, to a range where the partition panels 18 and 19 are arranged. Even in this case, the second guide box 13 rotates to ensure the passage of the crew.

  Further, in the present embodiment, the door panels 16 and 17 are of a double pull type, but instead of this, a single pull type may be used.

  In the present embodiment, the second guide box 13 is manually opened and the motor 36c is driven to return to the origin. However, the present invention is not limited to this. For example, the motor 36c may be omitted, and the second guide box 13 may be rotated only manually, or may be driven by the motor 36c when the crew passage 28 is opened or closed.

  In the present embodiment, the controller 55 is divided into the APG control unit 56 and the FDP control unit 57. However, the controller 55 may be integrated.
