Description

The present disclosure relates to platform door devices.

In recent years, platform door devices that open and close doors have been installed on platforms provided in the station premises of track vehicles (railroad vehicles, etc.). The platform door device plays a role of improving the safety of passengers by preventing people and objects from falling onto the track and coming into contact with the track vehicle.

Conventional platform door devices include a full-height type that completely separates the platform from the track, a high-waist door opening / closing type, and an elevating type provided with a rope or a bar. These types are selected by the railway operator according to the platform space of the station, the strength of the platform, the door position of the vehicle to be stopped, the number of doors, and the like.

Patent Document 1 below discloses an invention in which a sliding door installed on a leg opens and closes an entrance / exit, and a sliding door driving device is built in the leg.

In any of the above-mentioned types of platform door devices, a housing (door pocket) surrounded by plate-shaped members is installed in a range excluding the opening provided corresponding to the vehicle door. The housing includes a support unit such as a door or a bar, a drive unit, a control unit, and the like. The conventional housing is a factor that hinders visibility when a crew member or a station staff member checks between the platform door device and the vehicle when an abnormality occurs.

Further, at a station where a vehicle such as a limited express passes, a large overturning load is applied to the home door device due to the passing wind when the vehicle passes. Further, at the ground station, an overturning load due to a wind speed of 50 m / sec is applied to the platform door device in a strong wind. Therefore, conventionally, a method of increasing the rigidity of the platform door device has been adopted, and the weight of the platform door device has increased and the load applied to the fixed portion of the platform has also increased. To address this, work may be required to increase the strength of the platform.

As a result, the time and cost required for installation work will increase, and the burden on railway operators will increase, resulting in low cost effectiveness. At stations with few passengers, the installation of platform door devices will not proceed and will not spread. There is.

The present disclosure has been made in view of such circumstances, and an object of the present disclosure is to provide a platform door device having a simple structure and capable of being installed quickly and easily.

Hereinafter, the platform door device 1 according to the embodiment of the present disclosure will be described with reference to the drawings.
The platform door device 1 is installed on the platform 60 at which the train stops, and prevents people and objects from falling onto the track (railroad track) through which the train passes from the platform 60, and that people and objects come into contact with the vehicle 50. Suppress or prevent. The platform door device 1 has a height of, for example, about 1100 mm.

As shown in FIGS. 1 to 4, the platform door device 1 includes a fixed fence 2, a slide door 3, a drive unit 4, an obstacle sensor 5, a control panel 6, and the like. 1 and 2 show a state in which the sliding door 3 closes the opening, and FIGS. 3 and 4 show a state in which the sliding door 3 closes the opening.

A plurality of fixed fences 2 are provided along the edge of the platform 60. The fixed fence 2 is installed at a position of, for example, about 400 mm from the edge of the platform 60. The fixed fence 2 is fixed on the platform 60. As shown in FIGS. 8 to 10, the fixed fence 2 is made of metal, for example, and is made of an outer frame member 7, a rod-shaped member 8 provided inside the outer frame member 7, or a plate-shaped member having an opening. Become. The outer frame member 7 is formed by combining, for example, a tubular member or the like. The rod-shaped member 8 provided inside the outer frame member 7 or the plate-shaped member having an opening is, for example, a metal rod, punching metal, or the like. The rod-shaped member 8 may be arranged in the vertical direction inside the outer frame member 9 as shown in FIG. 11, or may be arranged in the horizontal direction as shown in FIGS. 15 and 17.

Inside the outer frame member 7 of the fixed fence 2, a rod-shaped member 8 or a plate-shaped member having an opening is provided, and the wind pressure is higher than when a plate-shaped member having no opening, for example, a metal plate is installed. It is less affected and visibility is improved.

The two adjacent fixed fences 2 are installed at predetermined intervals so that an opening is formed at a position corresponding to the vehicle door 51 of the vehicle 50 that stops on the platform 60. The fixed fence 2 is installed along the edge of the platform 60 in addition to the position corresponding to the vehicle door 51. Passengers get on and off the vehicle 50 through the openings formed between the adjacent fixed fences 2. The length of the opening is preferably set based on the width of the vehicle door 51 and the stopping accuracy of the vehicle 50. For example, when the width of the vehicle door 51 is 1300 mm and the permissible stop position is 750 mm before and after the stop reference position (fixed position), the length of the opening is set to about 2800 mm.

In this way, the length of the opening has a margin with respect to the width of the vehicle door 51 in consideration of the stopping accuracy of the vehicle 50, so that even if the stopping position of the vehicle 50 deviates from the fixed position, the vehicle 50 It is possible to get on and off without adjusting the stop position.

The slide door 3 is supported by a drive unit 4 installed on the platform 60, and can slide and move along the fixed fence 2. As shown in FIGS. 11 and 12, the sliding door 3 is made of metal, for example, and has an outer frame member 9, a rod-shaped member 10 provided inside the outer frame member 9, or a plate-shaped member having an opening. The rod-shaped member 10 or the plate-shaped member having an opening is, for example, a metal rod, a punching metal, or the like. The rod-shaped member 10 may be arranged in the vertical direction inside the outer frame member 9 as shown in FIG. 11, or may be arranged in the horizontal direction as shown in FIGS. 15 and 16.

Inside the outer frame member 9 of the slide door 3, a rod-shaped member 10 or a plate-shaped member having an opening is provided, and the wind pressure is higher than when a plate-shaped member having no opening, for example, a metal plate is installed. It is less affected and visibility is improved.

A lower beam 11 is installed on the slide door 3 along the lower part of the slide door 3. The lower beam 11 is a rigid member, and a slide mechanism and a driving component are housed therein. Since the lower beam 11 is provided on the slide door 3 along the lower portion of the slide door 3, when the beam member installed on the slide door is installed at the middle portion in the height direction of the slide door or above the lower beam member 11. Compared with, visibility is improved.

As shown in FIGS. 11, 13 and 14, a linear guide rail 12 is installed on the side surface of the lower beam 11 as a slide mechanism. The linear guide rail 12 is provided from one end to the other end of the lower beam 11. The linear guide block 13 that engages with the linear guide rail 12 and slides along the linear guide rail 12 is installed, for example, on the upper part of the drive unit 4. The linear guide block 13 is installed on a support portion 14 fixed to the platform 60. The slide door 3 moves along the fixed fence 2 by a slide mechanism including a linear guide rail 12 and a linear guide block 13 at the lower part.

An outer frame member 9 is connected to the upper surface of the lower beam 11 of the slide door 3. As shown in FIGS. 11 and 13, if the lower beam 11 and the outer frame member 9 are detachably connected by a fastening screw 15 or the like, assembly is easy and the installation site (platform 60). Can be carried in separately and assembled on site. It also facilitates maintenance.

Further, unlike the case where the lower beam 11 is composed of a rod-shaped member, the lower beam 11 has a planar portion in the height direction, and the difference from the fixed fence 2 becomes clear. It becomes easy to confirm the position of the sliding door 3. The distance from the lower beam 11 to the upper surface of the platform 60 is, for example, 200 mm or less, more preferably 150 mm or less. This makes it difficult for a person to fall from the gap under the lower beam 11 toward the track side. By installing the drive unit 4 at the lower part, the position of the lower beam 11 can be lowered downward.

In the platform door device 1, instead of a plate material without an opening, rod-shaped members 8 and 10 or a plate-shaped member having an opening is installed, so that the platform door device 1 is less susceptible to the influence of wind pressure when passing a train. As a result, the reinforcement of the platform 60 that supports the platform door device 1 can be reduced. Further, since the configuration is simpler than that of the conventional platform door device, the weight is reduced and the drive unit 4 supporting the slide door 3 becomes compact. Further, when the rod-shaped members 8 and 10 are used inside the outer frame members 7 and 9 of the fixed fence 2 and the slide door 3, the visibility of the crew and the station staff is improved as compared with the case where the plate members are provided.

A cam follower 16 is installed on the upper part of the slide door 3. Further, a guide rail 17 for guiding the cam follower 16 is installed on the upper part of the fixed fence 2. As a result, the slide door 3 moves along the fixed fence 2 while being supported by the guide rail 17 at the upper part. Further, according to this configuration, a door pocket (housing) surrounded by a plate-shaped member as in a conventional platform door device becomes unnecessary, and visibility is improved over the entire length of the vehicle 50 on the platform 60.

As shown in FIGS. 6 and 7, the drive unit 4 is fixed on the platform 60 separately from the fixed fence 2, and supports and drives the slide door 3. The drive unit 4 is installed below the intermediate portion in the height direction of the fixed fence 2 and supports the lower portion of the slide door 3. As a result, the center of gravity of the drive unit 4 is at the lower part, so that the slide door 3 can be stably supported. Further, the visibility is improved as compared with the case where the drive unit 4 is installed at the intermediate portion in the height direction or above the intermediate portion.

As shown in FIGS. 13 and 14, the drive unit 4 is a combination of the motor 18 and the drive mechanism, and a commonly used configuration can be applied. For example, the slide door 3 is driven by a configuration having a motor 18, a pulley 19, a motor pulley 20, and a belt 21. In the illustrated drive unit 4, the belt 21 is installed from one end to the other end of the lower end of the slide door 3, and the belt 21 is engaged with the pulley 19 and the motor pulley 20. As the motor 18 rotates, the motor pulley 20 rotates, and the positions of the pulley 19 and the belt 21 engaged with the motor pulley 20 change, so that the slide door 3 moves. The drive mechanism applied to the drive unit 4 may also be a rack and pinion mechanism, a chain mechanism, or the like.

In the present embodiment, as shown in FIGS. 5 and 6, the obstacle sensor 5 is fixed on the platform 60 by a support portion 22 different from the fixing fence 2. Since the fixed fence 2 and the obstacle sensor 5 are separately fixed on the platform 60, the fixed fence 2 does not need strength to support the full load of the obstacle sensor 5.

The obstacle sensor 5 is installed between the vehicle 50 and the slide door 3 entering the platform 60, and detects the presence or absence of a person or an object between the vehicle 50 and the slide door 3. As a result, the safety of passengers can be improved.

The contact detection sensor detects the presence or absence of a person or an object approaching the sliding door 3. As a result, it is possible to detect that a passenger inside the platform 60 is approaching the slide door 3, and by issuing an alarm or stopping the opening / closing operation of the slide door 3, safety can be improved.

The sliding door 3 is driven by a motor 18 and opens and closes based on a control signal. The sliding door 3 is opened / closed based on the detection result, for example, by detecting the operation of the crew or the opening / closing operation of the vehicle door 51. As a result, the sliding door 3 is automatically opened and closed. The control panel 6 having a control unit for controlling the opening and closing of the slide door 3 is installed on, for example, a fixed fence 2. Alternatively, the control panel 6 may be installed on the platform 60 separately from the fixed fence 2.

In the case of a home door device having a conventional structure, a vehicle is used to bring in a door pocket containing a sliding door. On the other hand, according to the present embodiment, the fixed fence 2, the slide door 3, the drive unit 4, the obstacle sensor 5, the control panel 6, and the like have a configuration that can be divided into the platform 60.
