Description

  The present invention relates to a platform movable fence device provided at a track-side edge of a platform of a track vehicle such as a railway.

  2. Description of the Related Art Conventionally, on platforms for track vehicles, movable fence devices for platforms are often installed for the purpose of preventing accidents of passengers falling on tracks and contact accidents between passengers and trains.

  Such a movable fence device for a platform is provided along a track-side edge of the platform, and includes a door pocket installed on the platform and a door that moves forward and backward with respect to the door pocket (for example, Patent Document 1). reference).

  Specifically, as illustrated in FIG. 7A, the box-shaped door pocket 100 is installed in an upright state from the end of the fixed fence 300 along the end edge of the platform PF. The door 200 moves forward and backward with respect to the door pocket 100. The door 200 is a plate-like member having a predetermined thickness, is supported so as to protrude from an opening 110 provided on one end side of the door pocket 100, and can be accommodated inside the door pocket 100 by moving forward and backward.

Japanese Patent No. 4651404

  By the way, as a configuration for realizing the forward / backward movement of the door 200, a pair of pulleys 121 and 122 fixed to a frame (not shown) and a belt 130 are provided inside the door pocket 100.

  The two pulleys 121 and 122 are rotatably supported by the frame, and a motor is coupled to one pulley 122. Further, a part of the door 200 is coupled to the belt 130 via a belt grip. Thereby, the forward / backward movement of the door 200 via the belt 130 and the belt gripper is realized by forward and reverse rotation of the motor.

  That is, in the conventional configuration, the door 200 is dragged by the belt 130. Therefore, the distance between the two pulleys 121 and 122 increases according to the movement amount of the door 200, and the two pulleys 121 and 122 are connected to the door pocket 100. It will be arranged at both ends.

  As shown in FIG. 7A, a guide rail 140 that guides the slide block 210 fixed to the door 200 is laid on the bottom of the door pocket 100. The length of the guide rail 140 is also set according to the amount of movement of the door 200. As a result, the guide rail 140 is provided with a length equivalent to that of the door pocket 100.

Thus, the conventional door pocket 100 also serves as a drive unit, and the drive mechanism is provided in the entire interior. Therefore, for example, when it is attempted to install a conventional movable fence where the fixed fence 300 is provided, it is necessary to remove the fixed fence 300 by the length of the door pocket 100. For example, when the length of the door pocket 100 is about 5 m as shown in FIG. 7A, it is necessary to remove the fixed fence 300 about 5 m as shown in FIG. 7B.

  Furthermore, the door 200 has a relatively large weight in order to ensure its strength. Although some have a honeycomb structure inside, even if the honeycomb structure is adopted, the weight of the door pocket 100 that supports the door 200 is increased.

  Therefore, the door pocket 100 has, for example, four base portions 150 as shown in FIG. 7A, and the time required for the installation work of the door pocket 100 is increased. Therefore, after removing the fixed fence 300, it is necessary to provide a temporary fence or arrange security guards, and the installation work of the door pocket 100 with the removal of the fixed fence 300 is very expensive.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a platform movable fence device that can reduce the time required for the installation work and, in turn, the cost for the installation work. It is in.

  The movable rail device for a platform according to claim 1, which has been made to achieve the above-described object, is provided at a track-side end edge of the platform, and is arranged at an interval corresponding to a passenger door of the track vehicle. Open and close the entrance.

  The platform movable fence device of the present invention includes a door having a frame structure composed of a horizontal bar-like member and a vertical bar-like member. The horizontal bar-shaped member extends in the forward / backward direction of the door, and the vertical bar-shaped member is connected to at least one end of the horizontal bar-shaped member and extends in the vertical direction. In addition, the horizontal bar-shaped member and the vertical bar-shaped member may be rod-shaped members, and may be formed of, for example, a metal material. Further, “horizontal” and “vertical” here do not have to be horizontal and vertical in a strict sense.

Moreover, the platform movable fence apparatus is provided with the drive part fixed to a platform. This drive unit supports the door and allows the door to move forward and backward in the forward / backward direction.
Here, particularly in the present invention, the door has a guide rail disposed along the horizontal bar-shaped member. On the other hand, the drive unit includes a slide block that engages with a guide rail that moves forward and backward together with the door, and a door feed mechanism that uses a frame structure. The door exit mechanism closes the doorway by causing the door to project from one end opening in the forward / backward direction of the door. Moreover, the doorway is opened by making the door protrude from the other end opening.

  For example, as shown in FIG. 2A, the door 30 includes horizontal pipes 31 to 33 as horizontal bar-shaped members and vertical pipes 34 and 35 as vertical bar-shaped members. Here, the door 30 has two guide rails 37 and 38, and the drive unit 20 has slide blocks 24 and 25 that engage with the guide rails 37 and 38. Then, the door delivery mechanism 23 of the drive unit 20 causes the door 30 to protrude from one end opening 27 in the forward / backward direction of the door 30, thereby closing the entrance / exit. Further, the door 30 is projected from the other end opening 26 to open the entrance / exit (see the two-dot chain line in the figure).

That is, in the present invention, the door has a frame structure, and the door is moved forward and backward by the door feed mechanism using the frame structure. At this time, when the entrance is opened, the door protrudes from the end opening of the drive unit. That is, the length of the drive part in the advancing / retreating direction of the door is smaller than that of the conventional door pocket. Further, the door has a guide rail along a horizontal bar-shaped member constituting the frame structure, and the drive unit side has a slide block that engages with the guide rail. This eliminates the need for laying guide rails as in the prior art. Furthermore, the weight of the drive unit can be reduced by adopting the frame structure for the door. As a result, the time required for the installation work can be reduced, and the cost for the installation work can be reduced.

By the way, the weight of the drive part which supports a door can be reduced by reducing the weight of a door. Therefore, the door may have a pipe frame structure in which at least one of the horizontal bar member and the vertical bar member is a tubular member. If it does in this way, the weight of a door can be reduced and, as a result, the weight of a drive part can be reduced.

  By actually adopting such a configuration, the base for installing the drive unit is sufficient at two places. As a result, it is easy to create a horizontal state as compared with the case where the foundation has three or more places (4 places in the past), so that the time required for installation work can be greatly shortened.

In addition, as shown in Claim 1 , it is the structure further provided with a door pocket. That is, a door pocket is further provided which is provided on the other end opening side of the drive unit and accommodates a door protruding from the end opening . Since the door during opening of the multiplication Fukuchi is accommodated in the door pocket, it contributes to the improvement of safety.

As shown in 請 Motomeko 1, the door pocket is attached to the fixed fence being disposed from the beginning in the track-side edge portion of the platform. In the present invention, since there is no drive mechanism that interferes with the fixed fence in the door pocket, it is not necessary to remove the original fixed fence. If it does in this way, installation of a door pocket will become easy and the time which installation work requires can be reduced. In addition, it is not necessary to remove the fixed fence corresponding to the door pocket part, and it is sufficient to remove only the fixed fence corresponding to the drive part part, so the time required for installation work can be reduced and safety is improved. Also contributes.

However, since the door is accommodated in the door pocket, there may be an interference portion with the door on the fixed fence. Therefore, as shown in claim 2 , the door pocket may be attached to a fixed fence from which an interference portion with the door is removed. In this case, although it is necessary to remove the interference portion with the door, the time required for the installation work can be reduced as compared with the conventional case, and the safety can be improved.

Although already mentioned that the guide rail is disposed along a horizontal bar-like member, specifically, it is conceivable to attach the bottom of the horizontal rod-like member. If it does in this way, a guide rail can be attached comparatively easily.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic perspective view of a movable platform fence device as seen from the platform side. FIG. 2A is a schematic side view schematically showing the configuration of the platform movable fence device, FIG. 2B is a schematic side view schematically showing the configuration of the drive unit, and FIG. It is an AA line schematic sectional drawing of b).

As shown in FIGS. 1 and 2A, the platform movable fence apparatus includes a door pocket 10, a drive unit 20, and a door 30.
The door pocket 10 is a box-shaped body, and is installed in an upright state along the edge of the platform PF. Here, the door pocket 10 is fixed to the fixed fence 40 that has been installed from the beginning. One end of the door pocket 10 is an opening 11, and the drive unit 20 is installed on the opening 11 side.

  The drive unit 20 has the same outer shape as the door pocket 10, and is continuously installed on the opening 11 side of the door pocket 10. The drive unit 20 is fixed to the platform PF by movable fence bases 21 and 22 (see FIG. 2A) provided in the lower part thereof. A part of the movable fence foundations 21 and 22 is embedded in the platform PF, and supports the support columns 61 and 62 (see FIG. 2B) constituting the frame of the drive unit 20. Specifically, as will be described later, the driving unit base 28 is fixed to the movable fence bases 21 and 22, and the support columns 61 and 62 are supported by the driving unit base 28 (see FIG. 5).

  The drive unit 20 has a mechanism for moving the door 30 forward and backward. Specifically, as shown in FIG. 2A, a door feed mechanism 23 and slide blocks 24 and 25 are provided. Furthermore, both ends of the drive unit 20 are end openings 26 and 27.

  The door 30 is supported by the drive unit 20 and moves forward and backward in an opening direction that opens an entrance / exit corresponding to a train entrance / exit door and a closing direction that closes the entrance / exit. FIG. 1 and FIG. 2 (a) show a state where the doorway is closed by the door 30.

  In other words, the door 30 projects from the one end opening 27 by the door delivery mechanism 23 of the drive unit 20, thereby closing the entrance. On the other hand, when the door 30 protrudes from the other end opening 26 (see the two-dot chain line in FIG. 2A), the entrance is opened.

  The door 30 has a pipe frame structure, and includes three horizontal pipes 31, 32, 33 extending in the forward / backward direction, and two vertical pipes 34, connected to both ends of the horizontal pipes 31-33 and extending in the vertical direction. 35. That is, the frame structure of the door 30 has a “day” shape that is long in the forward and backward direction. The gap between the frames is covered with a cover member 36 (see FIG. 1).

  Next, the drive mechanism of the drive part 20 is demonstrated using FIG.2 (b). The drive unit 20 includes two support columns 61 and 62 that are erected with an interval in the forward / backward direction of the door 30. As described above, the support columns 61 and 62 are supported by the movable fence foundations 21 and 22 of the drive unit 20 via the drive unit frame 28.

  The support columns 61 and 62 are connected by three connecting portions 63, 64, and 65 that extend in the forward / backward direction of the door 30. The connecting parts 63 to 65 are screwed to the columns 61 and 62 with bolts or the like (not shown).

The connecting portion 64 in the second stage from the top is disposed around the middle of the door 30 and the middle of the lower horizontal pipes 32 and 33 and supports the door feeding mechanism 23. That is, the door delivery mechanism 23 is disposed between the horizontal pipes 32 and 33 using the frame structure of the door 30. The door delivery mechanism 23 includes a motor 51, a toothed pulley 52 attached to the motor 51, and two guide rollers 53 and 54 disposed on both sides of the motor 51 so as to correspond to the toothed pulley 52.

  On the other hand, the horizontal pipe 32 in the middle stage of the door 30 has an opening extending in the forward and backward direction at a lower portion thereof, and has a toothed belt 55 arranged along the opening. Both end portions of the toothed belt 55 are fixed to end portions of the horizontal pipe 32 by stoppers (not shown). A portion of the toothed belt 55 is pulled out from the opening at a portion where the belt is engaged with the guide rollers 53 and 54 and meshed with the toothed pulley 52.

  Further, the first and third connecting portions 63 and 65 from the top are provided so as to be positioned below the upper and lower horizontal pipes 31 and 33 of the door 30. A plurality of slide blocks 24 and 25 arranged in the forward / backward direction of the door 30 are attached to the connecting portions 63 and 65. In FIG. 2A, the slide blocks 24 and 25 are schematically shown in a triangular shape.

Since the upper and lower horizontal pipes 31 and 33 have the same configuration, the upper horizontal pipe 31 will be described.
As shown in FIG. 2C, the horizontal pipe 31 has an opening extending in the advancing and retreating direction at a lower portion thereof, and a guide rail 37 having a “U” cross section is attached to the opening. On the other hand, the slide block 24 is attached by an attachment member 56 screwed to the side surface of the connecting portion 63, and is located inside the guide rail 37 of the horizontal pipe 31.

  That is, in this embodiment, the door 30 has guide rails 37 and 38 extending along the upper and lower horizontal pipes 31 and 33, and the drive unit 20 is provided on the guide rails 37 and 38 that move forward and backward together with the door 30. The slide blocks 24 and 25 are engaged.

  With such a configuration, when the motor 51 rotates forward and backward, the toothed pulley 52 rotates forward and backward, and the meshing position with the toothed belt 55 is changed, whereby the door 30 is moved forward and backward. Although the toothed pulley 52 is directly connected to the motor 51 here, the toothed pulley 52 may be attached with a reduction gear interposed. Further, instead of the motor 51, a hydraulic or pneumatic actuator may be employed. In addition, a gear may be directly connected to the motor 51, and in this case, the toothed belt 55 may be configured by a rack (gear).

  In addition, although it has already been described that the door pocket 10 is fixed to the fixed fence 40 that has been installed from the beginning, specifically, as shown in FIG. It is possible to attach the door pocket 10 so that the both sides of a side may be covered. In FIG. 3A, the door pocket 10 is attached to the fixed fence 40 by two attachment portions 12. Moreover, as shown in FIG.3 (b), it is possible to attach the door pocket 10 so that the track | orbit side of the fixed fence 40 may be open | released and only a home side may be covered. In FIG. 3 (b), the door pocket 10 is attached to the fixed fence 40 by one attachment portion 12. At this time, when there is a handrail portion 41 inclined toward the home side at the upper end of the fixed fence 40 and interferes with the forward / backward movement of the door 30, the handrail portion 41 is removed.

As described above in detail, in the present embodiment, the door 30 has a frame structure, and the door 30 is moved forward and backward by the door feed mechanism 23 using the frame structure. Specifically, using the frame structure of the door 30, the door delivery mechanism 23 is disposed so as to be positioned between the horizontal pipes 32 and 33 (see FIG. 2B). At this time, the door 30 projects from the end opening 26 of the drive unit 20 when the entrance is opened. That is, the length of the drive unit 20 in the door advance / retreat direction is smaller than that of the conventional door pocket. Further, the door 30 has guide rails 37 and 38 along the horizontal pipes 31 and 33 constituting the frame structure, and the drive unit 20 side has slide blocks 24 and 25 engaged with the guide rails 37 and 38. (See FIG. 2 (a)). This eliminates the need for laying guide rails as in the prior art. As a result, the time required for the installation work can be reduced, and the cost for the installation work can be reduced.

  The guide rails 37 and 38 are attached to the lower portions of the upper and lower horizontal pipes 31 and 33 (see FIG. 2C). Thereby, the guide rails 37 and 38 can be attached comparatively easily.

  In the present embodiment, the door 30 has a pipe frame structure including horizontal pipes 31 to 33 and vertical pipes 34 and 35. Thereby, the weight of the door 30 can be reduced and the weight of a drive part can be reduced. As a result, the time required for the installation work can be reduced, and the cost for the installation work can be reduced.

  Specifically, the movable fence foundations 21 and 22 for supporting the drive unit 20 are sufficient at two places, which is horizontal compared to the case where the foundations are three or more places (four places in the past). Since it becomes easy to create a state, the time required for installation work can be greatly reduced.

  Furthermore, in this embodiment, the door pocket 10 is provided and the door 30 which protrudes from the edge part opening 26 of the drive part 20 is accommodated at the time of opening of a passenger door. Thereby, since the door 30 is accommodated in the door pocket 10 when the entrance / exit is opened, it contributes to the improvement of safety.

  Moreover, the door pocket 10 is attached to the fixed fence 40 currently installed in the track | orbit side edge part of the platform PF from the beginning (refer Fig.3 (a) and (b)). Thereby, installation of the door pocket 10 becomes easy and the time required for installation work can be reduced. Moreover, it is not necessary to remove the fixed fence corresponding to the door pocket 10 portion, and it is sufficient to remove only the fixed fence corresponding to the drive portion 20 portion. In addition, when the handrail part 41 which inclines to the home side exists in the upper front-end | tip of the fixed fence 40, and interferes with the advancing / retreating movement of the door 30, the handrail part 41 needs to be removed.

  Specifically, when the drive unit 20 is installed in a range of less than 2 m as shown in FIG. 4A, a range of less than 2 m corresponding to the drive unit 20 as shown in FIG. 4B. Then, the fixed fence 40 is removed, and only the handrail portion 41 of the fixed fence 40 corresponding to the door pocket 10 is removed. As a result, it is possible to perform installation work at night time, and there is no need to provide a temporary fence or arrange security guards.

  Moreover, when removing the fixed fence 40 and installing the drive part 20, specifically, the movable fence base parts 21 and 22 shown to Fig.5 (a) are planted in the platform PF first. At this time, the movable fence foundations 21 and 22 are reliably planted on the platform PF by the anchors 21a and 22a. Next, the drive unit base 28 is attached to the movable fence bases 21 and 22, and then the main body portion is fixed to the drive unit base 28.

  At this time, since the fixed fence foundation 42 remains in the removed portion of the fixed fence 40 (indicated by symbol B), the movable fence foundations 21 and 22 are implanted so as to avoid the fixed fence foundation 42. There is a need.

  In this respect, in the present embodiment, the weight of the drive unit 20 is reduced, and the degree of freedom of arrangement of the movable fence foundations 21 and 22 is increased. Therefore, for example, as shown by symbol C in FIG. 5B, if the fixed fence foundation 42 is in a position where it interferes with one movable fence foundation 22, the one movable fence foundation 22 is shifted outward. The movable fence foundations 21 and 22 can be arranged avoiding the fixed fence foundation 42.

  In this embodiment, the door 30 corresponds to a “door”, the drive unit 20 corresponds to a “drive unit”, and the door pocket 10 corresponds to a “door bag”. Further, the horizontal pipes 31 to 33 constituting the frame structure of the door 30 correspond to “horizontal bar members”, the vertical pipes 34 and 35 correspond to “vertical bar members”, and the guide rails 37 and 38 are “guide rails”. It corresponds to. Furthermore, the slide blocks 24 and 25 of the drive unit 20 correspond to “slide blocks”, one end opening 27 corresponds to “one end opening”, and the other end opening 26 corresponds to “the other end”. The door delivery mechanism 23 corresponds to a “door delivery mechanism”. The fixed fence 40 corresponds to a “fixed fence”, and the handrail portion 41 of the fixed fence 40 corresponds to a “interference portion with the door”.

The present invention is not limited to the above-described embodiments, and can be implemented in various forms without departing from the technical scope thereof.
For example, it can also be implemented as a movable fence device for a platform as shown in FIG. This platform movable fence device also includes a door pocket 70, a drive unit 80, and a door 90, similar to the platform movable fence device of the above embodiment.

  Here, only the upper part of the door 90 has a pipe frame structure. Specifically, the lower portion of the door 90 is a plate portion 91 having a predetermined thickness, the vertical pipe 92 extending vertically upward from the end portion of the plate portion 91, and the plate portion from the upper end portion of the vertical pipe 92. A horizontal pipe 93 extending in parallel with 91 is provided.

  On the other hand, the door pocket 70 is attached to the fixed fence 40 so as to cover the fixed fence 40 from the platform side and the track side, and has a pipe storage portion 71 capable of storing a horizontal pipe 93 above the handrail portion 41. ing.

  With this configuration, as shown in FIG. 6B, the horizontal pipe 93 protruding from the driving unit 80 toward the door pocket 70 is stored in the pipe storage unit 71. In other words, the trombone movable fence It becomes a device. At this time, the door 90 is accommodated in the door pocket 70 so that the handrail portion 41 is positioned between the plate portion 91 and the horizontal pipe 93. The drive unit 80 is provided with a notch 81 for preventing pinching.

  Even if it does in this way, the same effect as the above-mentioned embodiment is produced. In this case, it is only necessary to remove the portion corresponding to the drive unit 80 of the fixed fence 40 installed from the beginning. That is, it is advantageous in that it is not necessary to remove the handrail portion 41 corresponding to the door pocket 70.

  In this case, the door 90 corresponds to a “door”, the drive unit 80 corresponds to a “drive unit”, and the door pocket 70 corresponds to a “door bag”. Further, the horizontal pipe 93 constituting the frame structure of the door 90 corresponds to a “horizontal bar member”, and the vertical pipe 92 corresponds to a “vertical bar member”. Furthermore, the fixed fence 40 corresponds to a “fixed fence”.
