Description

Gate device

The present invention relates to a gate apparatus for restricting the passage of people, vehicles and the like at an entrance and exit, and more particularly to a gate apparatus installed at a station platform and restricting the passage of passengers entering and leaving a train.

In the past, railway companies have been promoting the installation of a fall prevention fence along the side edge of the station home in order to prevent passengers from falling from the station home into the track. Not only does this fall prevention fence prevent the fall of passengers from the station home to the inside of the track, but it is also necessary to secure a passage for passengers getting on and off the train stopped at the station home. Therefore, there is a fall prevention fence provided with a slide door that slides in the horizontal direction to open and close at a position facing the door (vehicle door) of the train that has stopped at the station home (see Patent Document 1). The fall prevention fence is normally configured to be closed when the slide door is closed and allowing passengers to get in and out of the train stopped at the station home. By opening the slide door, a passage for passengers is secured.

Also, in place of the slide door, a fall prevention fence is proposed in which a movable fence that slides up and down along the columns is bridged between two adjacent columns erected at the side end of the station platform. (See Patent Document 2). This fall prevention fence is provided with a movable fence at a position facing the door (vehicle door) of the train that has stopped at the station home. In the fall prevention fence, the movable fence is normally positioned at a height of several tens cm to about 1 m, to prevent passengers from falling into the track from the station home. In addition, when allowing passengers to get in and out of the train stopped at the station home, the movable fence is raised to a height of about several meters (2 to 3 m) to secure a passage for allowing the passenger to get in and out of the train.

Japanese Patent Laid-Open No. 2000-16280 JP 2004-322823 A

However, the number of vehicle doors provided in one vehicle (one vehicle) differs depending on the type of train. In addition, the length of the vehicle also varies depending on the type. That is, the distance between the vehicle doors is different depending on the type of train.

As described above, the fall prevention fence needs to secure a passage allowing the passenger to get on and off the train stopped at the station home. In other words, the fall prevention fence should be configured such that the position facing the vehicle door is opened and closed by the slide door or the movable fence for all the trains stopping at the installed station home.

In the configuration of Patent Document 1, when the slide door is opened, a door pocket for housing the slide door is necessary. The space for providing the door bag limits the width of the sliding door, the distance between the sliding doors, and the like. For this reason, in the case of the station home where there are many types of trains to be stopped, it is difficult to make the slide doors face the vehicle doors of various types of trains. In addition, when another type of train is newly stopped at the station home due to a schedule revision or the like, the vehicle door of the train may not face the slide door.

That is, there is a problem that the applicable range is restricted by the trains stopped at the station home, and the types of trains that can be stopped are restricted by the installed fall prevention fences (restriction of the diamond revision). The

Moreover, in the structure of patent document 2, since a movable fence is slid to an up-down direction, a door bag is not required like patent document 1. FIG. Therefore, the length of the movable fence can be set freely to some extent. For this reason, the problem like the patent document 1 mentioned above is suppressed. However, in order to slide this movable fence in the vertical direction, it is necessary to set up a pillar with a height of about 2 to 3 m at the station home. On the other hand, in the case of a subway station home, there is a problem that the height of the ceiling restricts the height of the columns that can be erected.

An object of the present invention is to provide a gate device which can suppress the limitation of the application range depending on the installation place and the environment.

In particular, the present invention provides a gate apparatus (so-called fall prevention fence) which is hardly affected by the type of train to be stopped and the ceiling height of the station home when applied to the station home. To aim.

The gate device of the present invention is configured as follows in order to solve the above-mentioned problems and to achieve the object.

The fixed support stands on each side of the entrance and exit. The movable support is slidably attached to the fixed support in the vertical direction with respect to each fixed support. Furthermore, the stop bar is bridged between the adjacent movable columns. And a movable support | pillar drive part slides up and down with respect to the fixed support | pillar to which the said movable support | pillar is attached for every movable support | pillar. The movable support slides relative to the fixed support to a position projecting above the upper end of the fixed support.

For this reason, when lowering the movable support to the lower limit, the stop bar is positioned at a height of several tens cm to 1 m, and when raised to the upper limit, the stop bar reaches a height of approximately 2 m. However, the height of the fixed support and the movable support can be reduced. Also, the stop bar may be bridged over the upper end of the movable support.

Therefore, the application range can be suppressed from being limited by the installation place and the environment. In particular, when applied to a station home, the effects of the type of train to be stopped and the ceiling height of the station home can be sufficiently suppressed.

In addition, a plurality of stop bars may be vertically arranged between the movable columns and bridged, and the stop bars other than the uppermost stop bar may be slidably attached in the vertical direction.

In this case, a stop bar drive for driving the lower stop bar in the vertical direction is provided, and for the stop bar located between the uppermost stop and the lower stop bar, the up-down direction of the lower stop bar It is preferable that the slide be interlocked with the slide.

Furthermore, the load applied to the drive of the lowermost stop bar by the stop bar driving unit is monitored, and when the load fluctuates beyond a predetermined range, the lowermost stop bar of the stop bar driving unit The driving may be stopped.

According to the present invention, it is possible to suppress the limitation of the applicable range depending on the installation place and the environment thereof. In particular, when applied to a station home, the effects of the type of train to be stopped and the ceiling height of the station home can be sufficiently suppressed.

Hereinafter, an embodiment of a gate device according to the present invention will be described. Here, a fall prevention fence will be described as an example to prevent a passenger waiting for a train at the station home from falling into the track from the station home.

FIG. 1 is a schematic view showing an installation example of a fall prevention fence at a station platform. FIG. 1A is a plan view of the station home as viewed from above, and FIG. 1B is a plan view of the side end of the station home as viewed from the opposite side. As shown in FIG. 1, the fall prevention fence is installed by alternately arranging the movable fence 1 and the fixed fence 2 along the side end of the station home. Each movable fence 1 corresponds to the gate device according to the present invention. The fall prevention fence stops at the installed station home, and the movable fence 1 is installed at a position where the vehicle doors of these trains face each other regardless of the type of train on which the passengers get on and off. As described above, the number of vehicle doors and the length of the vehicle vary depending on the type of train vehicle, and the distance between the vehicle doors varies accordingly. The width of the movable fence 1 is wider than the maximum width of the vehicle door in the type of train that stops at the station home.

In addition, the movable fence 1 only needs to face the whole of the vehicle door of the train for each type of train that stops at the station home, and there is no particular problem even if there is a portion facing the portion that is not the train door.

Moreover, the space | interval of the movable fence 1 which adjoins and the fixed fence 2 should just be the space (several tens cm or less) which a person can not pass through, and even if these contact, there is no problem in particular.

FIG. 2 is a schematic view showing a movable fence. FIG. 2 is a plan view seen from the side facing the vehicle door of the train. Further, FIG. 2A shows a closed state, and FIG. 2B shows an open state.

The movable fence 1 includes a fixed support 11, a movable support 12, and a stop bar 13. The fixed support 11 is installed at the side end of the station home. A space between two fixed columns 11 is a passage for passengers getting on and off the train. In other words, regardless of the type of train that stops at the station home, the two fixed columns 11 are installed so as to cover the positions where the vehicle doors of the trains face each other.

The movable support 12 is attached to the fixed support 11 so as to be vertically slidable with respect to the fixed support 11. When the movable support 12 is lowered to the lowermost position (closed state), the upper end thereof is positioned slightly higher than the upper end of the fixed support 11. Further, the stop bar 13 is bridged near the upper end of the movable support 12. When the movable support 12 is lowered to the lowermost position, the stop bar 13 is located at a height of about 1 m from the surface of the station home.

In addition, when the movable support 12 is raised to the uppermost position (open state), the upper end of the movable support 12 is located at a height of about 2 m from the surface of the station home. The movable support 12 is described as being configured to slide about 1 m in the vertical direction with respect to the fixed support 11.

The stop bar 13 is approximately 1 m high when the movable support 12 is located at the lowermost level, and prevents a drop of a passenger from the station home into the track. In addition, the stop bar 13 is approximately 2 m high when the movable support 12 is located at the uppermost stage, and does not prevent the passage of passengers for the trains parked at the station home.

The stop bar 13 may be positioned slightly above the upper side of the train door when the movable support 12 is located at the uppermost stage.

Further, inside the fixed support 11, a movable support drive unit 21 that slides the movable support 12 in the vertical direction is provided. The movable column drive unit 21 may be provided inside the movable column 12.

FIG. 3A is a view showing the configuration of the main part of the movable column drive unit. FIG. 3 (B) is a schematic view illustrating a mechanism for sliding the movable support in the vertical direction. The movable column drive unit 21 has a motor 22 as a drive source, a drive control unit 23 for controlling the drive of the motor 22, a belt 24 driven by the motor 22, and the movable column 12 positioned at the lowermost stage. And a sensor 25b for detecting that the movable support 12 is positioned at the top. An instruction (opening and closing instruction) for raising and lowering the movable support 12 is input to the drive control unit 23. The input related to the open / close instruction can be performed by a switch operation not shown. Further, the drive control unit 23 detects the rotational speed of the motor 22 by an encoder signal.

A belt 24 is stretched around the inside of the fixed support 11. The belt 24 is an endless belt formed in a ring shape. The movable support 12 is attached to a belt 24 provided inside the fixed support 11, as shown in FIG. 3 (B). The belt 24 is rotationally driven by the driving force of the motor 22. The motor 22 can rotate in forward and reverse directions. Here, when the motor 22 rotates in the forward direction, the movable support 12 ascends, and when the motor 22 rotates in the reverse direction, the movable support 12 descends. The drive control unit 23 stops the motor 22 when detecting that the movable support 12 has reached the lowermost stage or the uppermost stage by the

sensor

25a or 25b. Further, the drive control unit 23 performs constant power control to set the rotational speed of the motor 22 to a predetermined speed, and at this time, when the amount of reduction of the rotational speed of the motor 22 exceeds a predetermined size, the motor 22 Stop.

FIG. 4 is a flowchart showing the operation of this movable fence. When the train does not stop at the station home, the movable fence 1 positions the movable support 12 at the lowermost stage. The movable fence 1 enters the station home and is installed at a position facing the vehicle door of the train stopped at the stop position. When the train stops at the stop position, an input for raising the movable support 12 (an input for an open instruction) is performed on the drive control unit 23. Specifically, a conductor of a train or a station worker operates an open switch (not shown). In addition, it may be configured to automatically detect that the train has stopped at the station home.

When the start time is input (s1), the drive control unit 23 drives the motor 22 to start an operation of moving the movable support 12 upward with respect to the fixed support (lifting of the movable support 12) (s2) . The drive control unit 23 performs constant power control to set the rotational speed of the motor 22 to a predetermined speed. The drive control unit 23 detects that the movable support 12 has reached the uppermost stage (upper stop position) by the sensor 25b (s3), or the change (reduction amount) of the rotational speed of the motor 22 is a predetermined size Monitor whether it is over (overload) (s4). When detecting that the movable support 12 has reached the upper stop position, the drive control unit 23 stops the motor 22 (s5). Also, when an overload is detected, the motor 22 is stopped (s6). When the drive control unit 23 stops the motor 22 at s6, the drive control unit 23 notifies an abnormality (s7), and ends the present process. The station clerk recognizes the occurrence of the abnormality by the notification of the abnormality and responds to the abnormality.

Further, when the drive control unit 23 stops the motor 22 at s4, the vehicle door of the train stopped at the station home is opened. This allows the passenger to get on and off the train.

The conductor or the station staff performs an input for lowering the movable support 12 (an input for a closing instruction) when the getting on / off of the passenger with respect to the train stopped at the station home is finished and the vehicle door of the train is closed. At this point, the train has not left.

When the closing start time is input (s11), the drive control unit 23 drives the motor 22 to start an operation to slide the movable support 12 downward with respect to the fixed support (descent of the movable support 12) (s12) ). The drive control unit 23 performs constant power control to set the rotational speed of the motor 22 to a predetermined speed. The drive control unit 23 detects that the sensor 25a has detected that the movable support 12 has reached the lowermost stage (lower stop position) (s13), or a change (decrease amount) in rotational speed of the motor 22 is predetermined. To monitor whether the size becomes large (overload) (s14). When detecting that the movable support 12 has reached the lower stop position, the drive control unit 23 stops the motor 22 (s15). Also, when an overload is detected, the motor 22 is stopped (s16). When the motor control unit 23 stops the motor 22 at s16, the drive control unit 23 sends an abnormality notification (s17), and ends the present process. The station clerk recognizes the occurrence of the abnormality by the notification of the abnormality and responds to the abnormality.

In addition, when the drive control unit 23 stops the motor 22 at s14, the present process ends. After this, a train that has stopped at the station home will depart.

As described above, since the movable fence 1 is configured to slide the movable column 12 in the vertical direction with respect to the fixed column 11, installation is simple and the type of train to be stopped and the ceiling height of the station home It can be applied with almost no influence by

Further, in the above example, one stop bar 13 is hung around the movable support 12, but as shown in FIG. 5, two stop bars 13 and 14 may be run around. FIG. 5A shows the closed state, FIG. 5B shows the intermediate state when transitioning from the closed state to the open state, and FIG. 5C shows the closed state. .

As shown in FIG. 5, two stop bars 13 and 14 (hereinafter sometimes referred to as upper stop bar 13 and lower stop bar 14) are arranged vertically in the vertical direction and spanned over the movable support 12 , It is possible to prevent the passengers from falling into the track from the station home more reliably. The upper restraint bar 13 has a height of about 1 m from the lower end of the movable support 12, and the lower restraint bar 14 slides in the height range of about 50 cm to 1 m from the lower end of the movable support 12.

In addition, this movable fence 1 is also provided with the movable support drive unit 21 described above. Here, the description of the movable column drive unit 21 is omitted.

Moreover, the movable fence 1 of this example is provided with the stop bar drive part 31 which slides the lower side stop bar 14 to an up-down direction. FIG. 6A is a view showing the configuration of the main part of the stop bar driving unit. FIG. 6 (B) is a schematic view illustrating a mechanism for sliding the stop bar in the vertical direction. The stop bar drive unit 31 has substantially the same configuration as the movable support drive unit 21 described above, and a motor 32 as a drive source, a drive control unit 33 for controlling the drive of the motor 32, and a belt driven by the motor 32. 34, a sensor 35a that detects that the lower stop bar 14 is at the lowermost level, and a sensor 35b that detects that the lower stop bar 14 is at the uppermost level. The drive control unit 33 receives an instruction (opening / closing instruction) for raising and lowering the lower stop bar 14. The input related to the open / close instruction is input from the movable support driving unit 21 described above. Further, the drive control unit 33 detects the rotational speed of the motor 32 by an encoder signal.

A belt 34 is stretched around the inside of the movable support 12. Like the belt 24, the belt 34 is also an endless belt formed in a ring shape. The lower stop bar 14 is attached to a belt 34 provided inside the movable support 12, as shown in FIG. 6 (B). The belt 34 is rotationally driven by the driving force of the motor 32. The motor 32 can rotate in forward and reverse directions. Here, when the motor 32 rotates in the forward direction, the lower stop bar 14 ascends, and when the motor 32 rotates in the reverse direction, the lower stop bar 14 lowers. The drive control unit 33 causes the lower stop bar 14 to move to the lowermost stage (about 50 cm in height) or the uppermost stage (a height at which the upper stop bar 13 abuts (or approaches)) by the

sensor

35a or 35b. When it is detected, the motor 32 is stopped. In addition, the drive control unit 33 performs constant power control to set the rotational speed of the motor 32 to a predetermined speed, and at this time, when the reduction amount of the rotational speed of the motor 32 exceeds a predetermined size, the motor 32 is Stop.

This movable fence 1 basically executes the process shown in FIG. 4 in the same manner as the movable fence 1 described above, but between the above-described s5 and s11, the lower restraint bar lifting process shown in FIG. While being performed, it differs in the point which performs lower side stop bar descent processing shown in FIG. 8 after s15 mentioned above. The train which has stopped at the station home opens the vehicle door when the lower stop bar lifting process shown in FIG. 7 is completed. In addition, after the lower stop bar lowering process shown in FIG. 8 is completed, the train departs from the station home.

The lower stop bar lifting process will be described with reference to FIG. When the drive control unit 33 receives an instruction to raise the lower stop bar 14 (s21), the drive control section 33 operates the motor 32 to slide the lower stop bar 14 upward with respect to the movable support 12 (lower stop Start the rising of the bar 14 (s22). The upward instruction of the lower restraint bar 14 is input from the drive control unit 23 of the movable column drive unit 21. When the motor 22 is stopped at s5 (the state shown in FIG. 5B), the drive control unit 23 inputs an instruction to raise the lower stop bar 14 to the drive control unit 33.

The drive control unit 33 performs constant power control to set the rotational speed of the motor 32 to a predetermined speed. The drive control unit 33 detects that the lower stop bar 14 has reached the uppermost stage (upper stop position) by the sensor 35b (s23), or the change (decrease amount) of the rotational speed of the motor 32 is predetermined. Monitor whether the size becomes large (overload) (s24). When the drive control unit 33 detects that the lower stop bar 14 has reached the upper stop position, the drive control unit 33 stops the motor 32 (s25), and ends the present process. Also, when an overload is detected, the motor 32 is stopped (s26). When the motor control unit 23 stops the motor 32 at s26, the drive control unit 23 sends an abnormality notification (s27), and ends the present process. The station clerk recognizes the occurrence of the abnormality by the notification of the abnormality and responds to the abnormality.

As described above, since the movable fence 1 is configured to slide the lower restraint bar 14 upward with respect to the movable support 12, the height for raising the movable support 12 corresponds to the movable fence 1 of the above-described embodiment. It may be about the same height.

Next, the lower stop bar lowering process will be described with reference to FIG. The drive control section 33 operates the motor 32 to slide the lower stop bar 14 downward with respect to the movable support 12 when the lowering instruction of the lower stop bar 14 is input (s 31) (lower stop The lowering of the bar 14 is started (s32). The lowering instruction of the lower restraint bar 14 is input from the drive control unit 23 of the movable column drive unit 21. When the motor control unit 23 stops the motor 22 in s15, the drive control unit 23 inputs an instruction to lower the lower stop bar 14 to the drive control unit 33.

The drive control unit 33 performs constant power control to set the rotational speed of the motor 32 to a predetermined speed. The drive control unit 33 detects with the sensor 35a that the lower stop bar 14 has reached the lowermost position (lower stop position) (s33), or the change (decrease amount) in the rotational speed of the motor 32 is previously determined. It is monitored whether it becomes a defined size (overload) (s34). When the drive control unit 33 detects that the lower stop bar 14 has reached the lower stop position, the drive control unit 33 stops the motor 32 (s35) and ends the present process. Also, when an overload is detected, the motor 32 is stopped (s36). When the motor control unit 23 stops the motor 32 at s36, the drive control unit 23 sends an abnormality notification (s37), and ends the present process. The station clerk recognizes the occurrence of the abnormality by the notification of the abnormality and responds to the abnormality.

As described above, since the movable fence 1 is configured to slide the lower restraint bar 14 in the vertical direction with respect to the movable support 12, when the vehicle is closed, the passenger falls from the station home into the track. It can be prevented reliably.

Further, in the above embodiment, although two stop bars 13 and 14 are stretched over the movable support 12, as shown in FIG. 9, three stop bars 13 to 15 (hereinafter referred to as the upper stop bars 13, The lower stop bar 14 and the intermediate stop bar 15 may be referred to as being suspended over the movable support 12. FIG. 9A shows the closed state, FIG. 9B shows the intermediate state when transitioning from the closed state to the open state, and FIG. 9C shows the closed state. .

In the movable fence 1, the intermediate restraint bar 15 and the lower restraint bar 14 are slidably attached to the movable support 12 in the vertical direction. Although the stop bar drive 31 may be separately provided for the middle stop bar 15 and the lower stop bar 14, the structure becomes complicated, so here, only the lower stop bar 14 stops bars. A drive unit 31 is provided, and the lower stop bar 14 pushes up the intermediate stop bar 15.

Specifically, as shown in FIG. 10, the upper restraint bar 13 and the intermediate restraint bar 15 are connected by an elastic member 41 such as a spring. The lower stop bar 14 is configured to be slid in the vertical direction by the stop bar driving unit 31 as in the example described above. As shown in FIG. 10A, the intermediate restraint bar 15 is positioned approximately halfway between the upper restraint bar 13 and the lower restraint bar 14 by the biasing force of the elastic member 41 in the normal state (closed state), as shown in FIG. In other words, the elastic member 41 has an elastic force that causes the intermediate restraint bar 15 to be positioned approximately halfway between the upper restraint bar 13 and the lower restraint bar 14 in the normal state (closed state).

As the lower bar driving portion 31 slides (lifts) the lower lower bar 14 upward, the lower lower bar 14 abuts against the intermediate lower bar 15 (see FIG. 10B). Furthermore, since the restraint bar driving unit 31 slides the lower restraint bar 14 upward, the intermediate restraint bar 15 slides upward with the lower restraint bar 14 against the elastic force of the elastic member 41. Then, as shown in FIG. 10 (C), the upper restraint bar 13, the intermediate restraint bar 15, and the lower restraint bar 14 are in a close state (opened state).

In addition, since the opening and closing process of the movable fence 1 is simultaneous with the movable fence 1 provided with the two stop bars 13 and 14 described above, the description is omitted here.

Further, as shown in FIG. 11, a sheet 42 provided with a bellows-like fold may be attached between the upper restraint bar 13 and the lower restraint bar 14. FIG. 11A shows the closed state of the movable fence, and FIG. 11B shows the opened state of the movable fence. FIG. 11C is a cross-sectional view showing the folded sheet 42 positioned between the upper restraint bar 13 and the lower restraint bar 14.

Further, as shown in FIG. 12, the sheet 42 stretched between the upper restraint bar 13 and the lower restraint bar 14 is wound by rotating the upper restraint bar 13 forwardly, and the upper restraint bar 13 is reversely rotated. It may be configured to let out and let out. FIG. 12A shows the closed state of the movable fence, and FIG. 12B shows the opened state of the movable fence. FIG. 12C is a cross-sectional view showing the sheet 42 taken up by the upper restraint bar 13. In this way, the lower stop bar 14 can be slid upward by rotating the upper stop bar 13 forward and winding the sheet 42. In addition, the lower restraint bar 14 can be slid downward by its own weight by feeding the seat 42 by rotating the upper restraint bar 13 in the reverse direction.

In addition, since the opening and closing process of the movable fence 1 is simultaneous with the movable fence 1 provided with the two stop bars 13 and 14 described above, the description is omitted here. However, in terms of hardware, the motor 32 does not drive the belt 34, but differs in that the upper stop bar 13 rotates forward and backward.

In the above example, although the present invention is applied to the movable fence 1 installed in the station home as an example, the present invention can also be used as a gate device provided in an entrance and the like where vehicles enter and leave at construction sites.
