Description

  The present invention relates to a gate device that restricts the passage of people, vehicles, and the like at entrances and exits, and more particularly to a gate device that restricts the passage of passengers getting on and off a train at a station platform.

  Conventionally, in order to prevent passengers from falling from the station platform into the track, railway companies have been proceeding with installation of fall prevention fences along the side edges of the station platform. This fall prevention fence must not only prevent passengers from falling from the station platform into the track, but also ensure a passage for passengers to get on and off the train that is stopped at the station platform. For example, there is a fall prevention fence provided with a sliding door that slides horizontally to open and close at a position facing a door (vehicle door) of a train stopped at a station platform (see Patent Document 1). This fall prevention fence is normally configured to close when the sliding door is closed and to allow passengers to get on and off the train stopped at the station platform. Passengers' passages are secured by opening the sliding door.

  In addition, instead of the sliding door, a fall prevention fence is proposed in which a movable fence that slides in the vertical direction along this pillar is bridged between two adjacent pillars standing on the side edge of the station platform. (See Patent Document 2). This fall prevention fence is provided with a movable fence at a position facing a door (vehicle door) of a train stopped at the station platform. The fall prevention fence is usually located at a height of about several tens of centimeters to 1 m with the movable fence, and prevents passengers from falling on the track from the station platform. Moreover, when permitting passengers to get on and off the train stopped at the station platform, the movable fence is raised to a height of about several meters (2 to 3 m) to secure a passage for passengers to get on and off the train.

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

  As described above, the fall prevention fence must be able to secure a passage for passengers getting on and off the train stopped at the station platform. In other words, the fall-preventing fence must be opened and closed by a sliding door or a movable fence at the position facing the vehicle door for all trains that stop at the installed station platform.

  The fall prevention fence of patent document 1 requires the door pocket which accommodates this sliding door, when a sliding door is opened. The space in which the door pocket is provided limits the width of the sliding door, the interval between the sliding doors, and the like. For this reason, in the case of a station platform with many types of trains to be stopped, it has been difficult to make the slide doors face the vehicle doors of various trains for all types of trains. In addition, when another type of train is newly stopped at the station platform due to a diamond revision or the like, the vehicle door of the train may not be opposed to the slide door.

  In this way, the applicable range is limited by the trains that stop at the station platform, and the types of trains that can be stopped by the installed fall prevention fences are limited (diamond revisions are limited). There was a problem.

  Moreover, in the structure of patent document 2, since a movable fence is slid to an up-down direction, a door pocket is not required like the structure of patent document 1. FIG. Therefore, the length of the width 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 the movable fence in the vertical direction, a pillar having a height of about 2 to 3 m must be erected on the station platform. On the other hand, in the case of a subway station platform, there is a problem in that the height of a column that can be erected is limited by the height of the ceiling.

  The purpose of the present invention is when restrictions on the applicable range due to the place of installation and its environment are suppressed, and the stop bar is located below and restricts the passage of people, vehicles, etc. at the entrance and exit It is an object of the present invention to provide a gate device that can easily cancel the traffic restriction of people and vehicles at the entrance and exit when an abnormality occurs.

  The gate device of the present invention has the following configuration in order to solve the above problems and achieve the object.

  The fixed struts are erected on both sides of the entrance / exit. The movable column is attached to each fixed column so as to be slidable in the vertical direction with respect to the fixed column. Furthermore, the restraining member is slidably slidable in the vertical direction between adjacent movable columns.

  For this reason, when the movable strut and the restraining member are lowered to the lower limit, the restraining member is located at a height of about several tens of cm to 1 m, and when the movable strut and the restraining member are raised to the upper limit, Even if the member reaches a height of about 2 m, the heights of the fixed column and the movable column are held down. Therefore, the applicable range can suppress the influence of the installation location and the environment. In particular, when applied to a station platform, restrictions due to the type of train to be stopped and restrictions due to the environment such as the ceiling height of the station platform can be sufficiently suppressed.

  Further, both ends of the restraining member are connected to a driving member stretched around a driving pulley arranged in the vertical direction inside each movable column. The restraining member slides in the vertical direction as the driving member is driven in the vertical direction.

  Further, a connecting shaft that rotates together with the driving pulley is attached between the driving pulleys located above the two movable columns. When the restraining member is manually lifted upward, the connecting shaft is rotated, and the driving pulley to which the connecting shaft is attached rotates in synchronization with the two movable columns. Thereby, the drive member provided in each of two movable support | pillars rotates synchronously.

  Therefore, when the restraining member is manually lifted upward, the restraining member can be lifted regardless of the position where the restraining member is held (any position such as the center of the restraining member or the left and right ends). It can be lifted substantially horizontally, and the traffic restrictions for people and vehicles at the entrance and exit can be easily released.

  Moreover, if the cylindrical shaft cover which lets a connection shaft pass is attached between two movable support | pillars, it can prevent that the person who is in the vicinity touches the rotating connection shaft. The connecting shaft rotates regardless of whether it is manual or automatic when the drive member is driven (when the stop member slides in the vertical direction).

  According to the present invention, the restriction on the applicable range due to the installation location and the environment is suppressed, and the restraining member is positioned below, and the passage of people, vehicles, etc. at the entrance / exit is restricted. When an abnormality occurs, the traffic restrictions for people and vehicles at the entrance and exit can be easily removed.

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

  FIG. 1 is a schematic diagram illustrating an installation example of a fall prevention fence in a station platform. FIG. 1A is a plan view of the station platform as viewed from above, and FIG. 1B is a plan view of the side end of the station platform as viewed from the opposite side. As shown in FIG. 1, this fall prevention fence has a plurality of movable fences 1 installed at appropriate intervals (2 m to 3 m intervals) along the side edges of the station platform. Each movable fence 1 corresponds to a gate device referred to in the present invention.

  As described above, the distance between vehicle doors varies depending on the type of train. Regardless of the type of train that stops at the installed station platform, this fall prevention fence is made wider than the width of the train door that stops at the station platform so that the movable fence 1 faces the vehicle door of these trains. ing. By opening the movable fence 1, a passage for passengers getting on and off the train is secured. In addition, by closing the movable fence 1, passengers at the station platform are prevented from falling into the track. In addition, in order to prevent passengers and the like at the station platform from falling between the adjacent movable fences 1 into the track, the fixed bar 2 is stretched between the adjacent movable fences 1. Although FIG. 1 shows an example in which two fixed bars 2 are arranged side by side between adjacent movable fences 1, the number of the fixed bars 2 may be one, or three or more. It may be.

  In addition, the movable fence 1 should just oppose the whole vehicle door of the train for every kind of train which stops at a station platform, and even if there is a part which opposes the part which is not a train door, there will be no problem in particular.

  FIG. 2 is a plan view seen from the station platform side facing the vehicle door of the train. FIG. 2 shows a state where the movable fence is closed (closed state).

  The movable fence 1 includes two fixed columns 11, two movable columns 12, and two stop bars 13 and 14. The fixed support 11 is erected on the side end of the station platform. A pedestal is attached to the station platform at the installation position of the fixed support 11. Between the two fixed columns 11 is a passage for passengers getting on and off the train. In other words, the two fixed columns 11 are installed so as to cover the positions where the vehicle doors of each train face each other regardless of the type of the train that stops at the station platform. The fixed column 11 has a height of about 130 to 150 cm. The fixed support 11 is a steel material that can withstand a lean load of about 100 kgf.

  Two movable struts 12 are attached to the fixed struts 11 so as to be slidable in the vertical direction with respect to the fixed struts 11. The movable column 12 is attached to the back surface (line side) of the fixed column 11. The movable strut 12 is a steel material having a height of about 130 cm. The restraining bars 13 and 14 are arranged between the two movable struts 12 so as to be lined up and down. The upper restraining bar 13 (hereinafter also referred to as the upper restraining bar 13) is a cylindrical (for example, cylindrical) pipe and is fixed near the upper end of the movable support column 12, as will be described later. doing. The upper stop bar 13 passes through a connecting shaft described later on the inside. On the other hand, the lower stop bar 14 (hereinafter also referred to as the lower stop bar 14) is attached to the movable column 12 so as to be slidable in the vertical direction. The lower side stop bar 14 corresponds to the stop member referred to in the present invention.

  When the movable fence 1 is in the closed state shown in FIG. 2, the upper stop bar 13 is about 130 cm high from the upper surface of the station platform, and the lower stop bar 14 is about 65 cm high from the upper surface of the station platform. . The restraining bars 13, 14 are, for example, PC tubes having an outer diameter of 48 mm and a thickness of 3.5 mm. When the movable fence 1 is in the closed state, the lower side stop bar 14 can be used by an infant (height of a 2-year-old child 80-90 cm) or a wheelchair user (wheelchair armrest height of about 60 cm) It is the height which prevents falling to a track | line through between the side stop bars 14. FIG. Further, the lower stop bar 14 has a height that makes it difficult for passengers and the like in the station platform to get on.

The stop bars 13 and 14 may be configured to be replaced with plates or the like as long as the passage of passengers and the like can be restricted.

  Further, between the adjacent movable fences 1, the two fixed bars 2 described above are lined up and down and hung on the fixed column 11. The lower fixed bar 2 has a height of about 65 cm from the upper surface of the station platform, and the upper fixed bar 2 has a height of about 130 cm from the upper surface of the station platform. The fixed bar 2 is, for example, a SUS tube having an outer diameter of 50 mm and a thickness of 2 mm. As described above, since the fixing bar 2 is attached to the fixing column 11, it is not necessary to separately prepare a column to which the fixing bar 2 is attached, and the appearance of the station platform is not impaired, and the installation cost of the fall prevention fence is suppressed. be able to.

  FIG. 3 is a block diagram showing the configuration of the main part of the movable fence. The movable fence 1 includes a control unit 50, a movable column drive control unit 51, a movable column drive motor 52, a stop bar drive control unit 53, a stop bar drive motor 54, a communication unit 55, and a notification unit 56. It is equipped with.

  The controller 50 controls the operation of each part of the movable fence 1. As described above, the movable fence 1 has the fixed struts 11 installed on both sides of the passenger passage, and the movable struts 12 are attached to the fixed struts 11 so as to be slidable in the vertical direction. The movable fence 1 is provided with a movable column driving motor 52 for each fixed column 11. The movable strut drive control unit 51 includes a movable strut drive motor 52 provided on the two fixed struts 11 so that the two movable struts 12 are displaced at substantially the same height in accordance with an instruction from the control unit 50. Control in conjunction.

  The fixed support 11 has an endless belt that is rotationally driven in the up-and-down direction stretched around the inside thereof. The movable column 12 is connected to an endless belt provided inside the fixed column 11. This endless belt is rotationally driven by the driving force of the movable column driving motor 52. The movable support 12 slides up and down with respect to the fixed support 11 as the endless belt rotates. The movable column drive motor 52 can rotate in the forward direction (the direction in which the movable column 12 rises) and in the reverse direction (the direction in which the movable column 12 descends).

  The movable column drive control unit 51 detects a sensor (not shown) that detects that the position of the movable column 12 with respect to the fixed column 11 is at the lower limit position and that the position of the movable column 12 with respect to the fixed column 11 is at the upper limit position. )have. Further, the encoder provided in the movable column driving motor 52 is configured to obtain the displacement amount of the movable column 12 according to the driving amount of the movable column driving motor 52.

  In addition, the movable fence 1 spans two stop bars 13 and 14 between movable struts 12 slidably attached to the two fixed struts 11 in the vertical direction. As described above, the upper stop bar 13 is fixed near the upper end portion of the movable column 12. Further, the lower stop bar 14 is attached to the movable column 12 so as to be slidable in the vertical direction. The movable fence 1 is provided with a stop bar drive motor 54 for each movable column 12. The stop bar drive control unit 53 is provided on the two movable struts 12 so that both ends of the lower stop bar 14 are displaced at substantially the same height with respect to the movable struts 12 in accordance with an instruction from the control unit 50. The stop bar drive motor 54 is controlled in conjunction.

  Although the details will be described later, the movable support column 12 has an endless belt that is driven to rotate in the up-and-down direction. The lower stop bar 14 is connected to the endless belt. This endless belt is rotationally driven by the driving force of the stop bar drive motor 54. The lower stop bar 14 slides in the vertical direction with respect to the movable column 12 as the endless belt rotates. The restraining bar drive motor 54 can rotate in the forward direction (the direction in which the lower restraining bar 14 rises) and in the reverse direction (the direction in which the lower restraining bar 14 descends).

  The stop bar drive control unit 53 detects that the position of the lower stop bar 14 with respect to the movable strut 12 is at the lower limit position and that the position of the lower stop bar 14 with respect to the movable strut 12 is at the upper limit position. It has a sensor (not shown). Further, the amount of displacement of the lower stop bar 14 according to the drive amount of the stop bar drive motor 54 can be obtained by the encoder provided in the stop bar drive motor 54.

  The communication unit 55 controls communication with a host device such as a train stopped at the station platform or a management device installed in the station office. Communication with the train is performed via a known transponder. The notification unit 56 performs warning notification by voice or the like to passengers and station attendants.

  Next, the opening / closing operation of the movable fence 1 will be briefly described. FIG. 4 is a diagram for explaining a change from the closed state of the movable fence to the open state.

  The movable fence 1 is normally closed, and when the train arrives at the station platform, the movable fence 1 shifts to the open state. And when boarding / alighting of the passenger with respect to a train is completed, it will transfer to a closed state.

  When the movable fence 1 receives an opening instruction in the communication unit 55, the movable column driving control unit 51 drives the movable column driving motor 52 and slides the movable column 12 upward. FIG. 4A shows the closed state of the movable fence 1. At this time, the movable strut drive control unit 51 performs constant power control to set the rotational speed of the movable strut drive motor 52 to a predetermined normal speed, and slides the movable strut 12 upward. For example, the movable support 12 is slid upward at 40 cm / s. At this time, the movable column drive motor 52 is rotated forward. When the movable column 12 reaches the upper limit position, the movable column drive control unit 51 stops the movable column driving motor 52 (see FIG. 4B).

  Thereafter, the stop bar drive controller 53 drives the stop bar drive motor 54 and slides the lower stop bar 14 upward. At this time, the stop bar drive control unit 53 performs constant power control to set the rotation speed of the stop bar drive motor 54 to a predetermined normal speed, and slides the lower stop bar 14 upward. For example, the lower stop bar 14 is slid upward at 40 cm / s. At this time, the stop bar drive motor 54 is rotated forward. When the lower stop bar 14 reaches the upper limit position, the stop bar drive control unit 53 stops the stop bar drive motor 54 (see FIG. 4C). This state is an open state. When in this open state, the lower stop bar 14 is located at a height of about 2 m from the upper surface of the station platform.

  Next, a state change of the movable fence 1 from the open state to the closed state will be described. FIG. 5 is a diagram illustrating a state change from the open state of the movable fence to the closed state. FIG. 5 (A) shows the open state of the movable fence 1 as in FIG. 4 (C).

  When the movable fence 1 receives a closing instruction in the communication unit 55, the movable column driving control unit 51 drives the movable column driving motor 52 and slides the movable column 12 downward. At this time, the movable strut drive control unit 51 performs constant power control to set the rotation speed of the movable strut drive motor 52 to a predetermined normal speed, and slides the movable strut 12 downward. For example, the movable support 12 is slid downward at 40 cm / s. At this time, the movable column drive motor 52 is rotated in the reverse direction. When the movable column 12 reaches the lower limit position, the movable column drive controller 51 stops the movable column drive motor 52 (see FIG. 5B).

  Thereafter, the stop bar drive control unit 53 drives the stop bar drive motor 54 and slides the lower stop bar 14 downward. At this time, the stop bar drive control unit 53 performs constant power control to set the rotation speed of the stop bar drive motor 54 to a predetermined normal speed, and slides the lower stop bar 14 downward. For example, the lower stop bar 14 is slid downward at 40 cm / s. At this time, the stop bar drive motor 54 is rotated in the reverse direction. When the lower stop bar 14 reaches the lower limit position, the stop bar drive control unit 53 stops the stop bar drive motor 54 (see FIG. 5C). This state is a closed state. FIG. 5C is the same closed state as FIG.

  Next, the sliding structure of the lower restraining bar 14 that is slidably attached to the movable column 12 in the vertical direction will be described. FIG. 6 is an enlarged view of the attachment position of the lower stop bar in the movable support column. As shown in FIG. 6, the end of the lower restraining bar 14 is attached to the drive case 21 (the drive case 21 holds the end of the lower restraining bar 14).

  The restraining bar drive control unit 53 slides the lower restraining bar 14 holding the end portion in the vertical direction by sliding the drive case 21 in the vertical direction with respect to the movable column 12. The movable strut 12 has a guide groove 22 for guiding the slide of the drive case 21 in the vertical direction. The movable column 12 has an opening surface communicating with the guide groove 22 formed on a side surface facing the other movable column 12.

  FIG. 7 is a schematic view showing a mounting structure (internal structure) of the restraining bar and the connecting shaft in the movable support column. FIG. 7 shows a state where the movable column 12 is in the upper limit position. As described above, each of the two movable struts 12 has an endless belt 31 that is rotationally driven in the up-and-down direction, stretched around the inside thereof. Each movable column 12 has two drive pulleys 32 and 33 arranged in the vertical direction attached inside. The endless belt 31 is stretched around two drive pulleys 32 and 33 arranged in the vertical direction.

  The lower drive pulley 32 is rotationally driven by the drive force of the stop bar drive motor 54. As described above, the restraining bar drive motor 54 is provided for each movable column 12 that spans the restraining bars 13 and 14. The upper drive pulley 33 is connected by a connecting shaft 34 that passes through the inside of the upper stop bar 13. The connecting shaft 34 rotates together with the upper drive pulley 33. When the stop bar drive motor 54 rotates and drives the lower drive pulley 32, the endless belt 31 rotates, and accordingly, the upper drive pulley 33 rotates. Further, the connecting shaft 34 rotates with the rotation of the upper drive pulley 33. Since the connecting shaft 34 passes through the inside of the upper stop bar 13 as described above, it cannot be touched from the outside. The upper stop bar 13 corresponds to the shaft cover referred to in the present invention.

  The drive case 21 inserted into the guide groove 22 is coupled to the endless belt 31 by a connecting member (not shown). Therefore, the drive case 21 slides in the vertical direction as the endless belt 31 rotates. Further, the drive case 21 holds the end of the lower stop bar 14. Therefore, as the drive case 21 slides, the lower stop bar 14 slides in the vertical direction.

  The direction in which the drive case 21 and the lower stop bar 14 slide is determined by the rotation direction of the lower drive pulley 32 by the stop bar drive motor 54.

  Next, a case where the lower stop bar 14 is manually lifted upward will be described. The lower stop bar 14 is lifted manually only when, for example, the lower stop bar 14 is positioned below and the passage of passengers is restricted (the movable strut 12 is positioned at the lower end). (Including the case where the vehicle is located at the upper end), and when it is necessary to cancel the passenger traffic restriction due to the occurrence of some abnormality (change in surrounding conditions, etc.).

  When a person in the vicinity lifts (or pushes up) the lower stop bar 14 at an appropriate position, the drive case 21 holding the end of the lower stop bar 14 is lifted upward. Since the drive case 21 is connected to the endless belt 31, the endless belt 31 rotates and the drive pulleys 32 and 33 rotate.

  Since the upper drive pulleys 33 in the two movable struts 12 are connected by the connecting shaft 34, the drive pulleys 32 and 33 in the two movable struts 12 rotate substantially synchronously.

  Therefore, when the lower stop bar 14 is manually lifted upward, wherever the lower stop bar 14 is located (where the center of the lower stop bar 14, the left and right ends, etc. Even if lifted), the lower restraining bar 14 is lifted substantially horizontally with almost no inclination. In other words, it is possible to prevent such a situation that the lower stop bar 14 is inclined and caught. For this reason, when an abnormality occurs, it is possible to easily release the passenger restriction at the entrance and exit, and to secure a passage for passengers. As a result, passenger safety can be improved.

  Further, the connecting shaft 34 rotates the driving pulleys 32 and 33 in the two movable struts 12 substantially synchronously even when the lower stopping bar 14 is slid in the vertical direction by the stopping bar driving motor 54. Further, since the drive pulleys 33 in the two movable struts 12 are connected by the connecting shaft 34, the restraining bar drive control unit 53 and the restraining bar drive motor 54 are provided on one movable strut 12, and the other It is good also as a structure which is not provided in the movable support | pillar 12.

  The endless belt 41 in the above example may be replaced with another member such as a chain. In the above example, the case where the present invention is applied to the movable fence 1 installed in the station platform has been described as an example. However, the present invention can also be used as a gate device provided at an entrance / exit where a vehicle enters and exits at a construction site or the like.
