Description

  The present invention is installed on a platform in a station of a rail vehicle, and is configured to constitute a platform door device that protects passengers from danger by preventing passengers from falling on railroad tracks or contacting with trains. Regarding the fence. In particular, the present invention relates to a flexible movable fence for different types of vehicles that can be applied to vehicles having different numbers of doors and different door intervals.

  The movable fence installed on the platform in the station is closed while the train is waiting, and when the train arrives at the platform, the door is opened to allow passengers to pass. Generally, it is fixedly installed on the platform. And a sliding door type door that can be freely moved in and out of the door pocket. In this movable fence, it is possible to allow a difference in the door opening position of the entrance / exit of the train due to the type of the train to be stopped or an error in the stopping position, and the movable fence opening can be formed at a position corresponding to the door opening position of the train. It is like that.

  By the way, when a train to which a vehicle having a different door opening number is connected in one train stops on the platform, or a plurality of types of trains that are organized by connecting vehicles having different door opening numbers respectively stop There is. For example, there is a case where a train that is usually composed of four-door vehicles but is limited to only a limited number of cars that are limited in the time zone of congestion is a six-door vehicle. In addition, a train that is composed of three-door vehicles and a train that is composed of four-door vehicles stop due to mutual entry, etc., or a train that is composed of all four-door vehicles and some six-door vehicles There is a platform that stops with mixed trains. When multiple types of trains with different door opening positions stop, even if the above-mentioned movable fence is to be provided, it is fixed to be accommodated with the movable fence door that opens corresponding to the door opening position of the train to be stopped. A sufficient boarding / alighting width cannot be secured due to the relationship with the door pocket. Such a situation exists in many existing railways and makes it difficult to install movable fences.

  It has a movable fence with a large opening width to cover a wide stop position range of the vehicle and a door leaf drawn into this movable fence, and the width of the open section formed by the opening operation of the left and right door leaves is set as the opening width. Regardless of this, there has been proposed a waist-high platform movable fence that is limited to a necessary limit and that can change the center position of the open section according to the vehicle stop position (see, for example, Patent Documents 1 and 2). In addition, the door includes an opening at both ends and a left and right linear rail provided therein, and a left and right door having a support member to which a slide block supported by the left and right linear rail is fixed and moving forward and backward from each opening of the door pocket. A waist-high platform movable fence that can accommodate different types of vehicles in which the distance between adjacent entrances and exits is different by taking a large opening has been proposed (for example, see Patent Document 2). These movable fences can be applied even to different types of vehicles when the difference (stop error) in the door opening position of the train stopped on the platform is small.

Similarly, as a full-screen type movable fence, a plurality of movable home doors are arranged in two rows shifted in a direction perpendicular to the longitudinal direction of the platform, depending on the type of train that stops on the platform and the stop position. Proposing to select a platform door to be moved and to open the platform door opening section corresponding to the train door opening position by opening the platform door opposite to the train door position to be stopped and to support different types of vehicles. (For example, see Patent Document 3).

  In Patent Document 1 and Patent Document 2, when a train formed by the 3-door vehicle and a train formed by a 4-door vehicle or a train formed by mixing 4-door vehicle and 6-door vehicle is stopped, respectively. Since the position of the door opening of each train is greatly different, it is difficult to arrange the short door pockets constituting the platform movable fence, and it is difficult to secure an opening for allowing the minimum necessary stop error. Moreover, in patent document 3, since it is a full screen type | mold, construction is large-scale in order to install in the existing railway platform, and there are many problems also in terms of construction period and price besides a narrow platform.

  An object of the present invention is to provide a waist movable type flexible movable fence for different types of vehicles that can be applied to a platform where different types of vehicles having different door opening positions and numerical apertures stop.

  In order to solve the above-mentioned problems, the present invention comprises a fixed fence, a door-bag-type intermediate door movably supported by the fixed fence, and a sliding door-type door that is housed in the intermediate door. In the flexible movable fence for different types of vehicles, the fixed fence is configured to have a narrow width, the intermediate door is slidably supported by the fixed fence and has openings at both ends, and the sliding door type is a moving direction of the intermediate door The sliding doors are supported on the left and right sides of the doorways adjacent to each other, and are stored and arranged in the thickness direction of the intermediate door.

  In the flexible movable fence for different types of vehicles according to the present invention, the intermediate door supported by the fixed fence is configured to be movable back and forth in any direction of an adjacent entrance and exit, and the sliding door type housed in the intermediate door Along with the door, it opens and closes freely for the stroke corresponding to the entrance / exit of different types of vehicles.

  The present invention relates to the above-mentioned flexible movable fence for different types of vehicles, wherein the upper part of the fixed fence is a U-shape and a slide block is supported and fixed on the upper surface of the bottom side, and the upper part of the intermediate door is turned upside down to form an L-shaped slide rail The intermediate door is fixed to the lower surface of the top of the L-shaped part that is inverted up and down, the slide rail of the intermediate door is supported on the slide block of the fixed fence, and the slide rail of the intermediate door opens and closes the slide block of the fixed fence Moving.

  The present invention is the above-described flexible movable fence for different types of vehicles, wherein the sliding door doors corresponding to each of the adjacent entrances and exits are attached to the intermediate door on the same plane in the thickness direction up and down on the same plane, The support portion of one door is arranged above the support portion of the other door and is slid.

  In the flexible movable fence for different types of vehicles, the present invention provides a rack at the lowermost part of each of the left and right sliding door type doors that are stacked and accommodated in the thickness direction of the intermediate door, A drive system in which a motor with a pinion corresponding to each of the racks is installed in the lower part, a rack is provided in the lowermost part of the intermediate door, and a motor with a pinion corresponding to the rack is installed in the fixed fence.

  As for the arrangement of the flexible movable fence and the movable fence in one vehicle, conventional movable fences are arranged at three positions of the connecting part and the central part, and two flexible movable fences are arranged between the movable fences. In the case of a six-door vehicle, the intermediate door holds the closed position, and the left and right entrance doors are accommodated in the intermediate door to obtain the required opening size. In the case of a 4-door vehicle, the intermediate door moves in the opening direction by the required opening, and the left and right entrance doors are accommodated in the intermediate door. At this time, one door in the moving direction of the intermediate door maintains the closed position.

  In the present invention, a narrow fixed portion fence (fixed fence) is separately installed to make the door pocket, which was a conventional fixed portion, movable, and the movable door pocket acting as an intermediate door can be slid on the fixed fence. The intermediate door is provided with openings at both ends, and the doors for adjacent entrances are stacked in the thickness direction so that they can be stored and opened, so the type of train that stops on the platform is detected. When a train type detection signal from the train type detection device or a pre-programmed train type signal is received, the doors for the entrance and exit and the intermediate door are opened and closed according to the type of train. Since the middle door and the two doors for the entrance / exit supported by the narrow fixed fence are flexibly movable, a large opening can be formed. Therefore, even if the train stopping on the platform is a different type of vehicle with different door opening positions, the movable fence opens and closes at the optimum position in any case.

  The intermediate door has a structure having a slide rail so that a slide block fixedly installed on the upper part of a narrow fixed fence can be moved in the door opening and closing direction. The slide rail installed on the upper part of the intermediate door is opened and closed with a slide block so that it can be completely stored and moved in the intermediate door, and the drive means is racked at the lower part of each of the intermediate door and the two entrance doors. A motor with a pinion that meshes with a rack installed on the intermediate door is installed on a fixed fence, and a motor with a pinion that meshes with a rack installed on each of two entrance doors is installed at both ends of the intermediate door. It installs and opens and closes the said intermediate door and two adjacent entrance doors flexibly.

  According to the present invention, an intermediate door is supported so as to be movable by a fixed fence having sufficient strength, and an adjacent doorway door is disposed on the intermediate door and is driven by a motor with a rack and a pinion. The present invention is sufficiently applicable to a platform where different types of vehicles having different door opening positions stop. In addition, the support structure that supports the support arrangement of each adjacent doorway door supported by the intermediate door on the same surface in the thickness direction makes it possible to minimize the thickness and is also effective for narrow platforms It is. The platform door using the flexible movable fence according to the present invention is provided with a fixed fence part and can be installed on an existing route that is almost the same as the installation of a movable fence with a proven track record as it has been known in the past.
