Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a movable tread device for filling the gap between a platform and a vehicle at a railway boarding/disembarking station.

In particular, the present invention is in the field of effectively utilizing Blatt-Bohms facing curved trajectories.

(Prior art) When the platform of a railway platform faces a straight track, there is no large gap between the platform and the vehicle, but when the platform faces a curved track, the platform dimensions are smaller than the vehicle. The gap between the vehicle and the platform is determined by the respective running trajectories of the edges and the center of the vehicle, so each entrance and exit of the vehicle has a different clearance from the platform. Large gaps occur at entrances and exits near the ends of vehicles. Conventionally, warning lights are installed in these large gaps.
Although warning announcements have been made, proactive efforts to eliminate or reduce gaps are generally not implemented.

Yozaki Gi + E) 1975 No. 58 (7) rl (CV
At the Kakogawa Test Line in ``Near Stem Characteristics and Actual Vehicle Tests'', we conducted a test using sliding movable treads to eliminate the gap between the vehicle and the vehicle. However, there are still unresolved problems, such as concerns about people getting their feet stuck due to the difference in level between the movable tread surface and the platform surface, and the lack of rigidity of the floor at the edge of the platform, which gives passengers a sense of anxiety.

[What the invention seeks to solve = 1, d) From the time of the above-mentioned test line to the present, progress has been made in unmanned boarding and alighting stations, one-man operation of rolling stock, and unmanned trains in order to save labor in railway operations. One of the ways to minimize trouble in these operations is to improve the security of passengers getting on and off the train. However, as mentioned above, there is a large gap between the platform facing the curved track and the vehicle, and in order to increase the safety level, it is necessary to eliminate this gap, or at least create a gap similar to that of the platform facing the straight track. I have come to feel a strong desire to fill it up.

Therefore, it is necessary to solve the problems of movable treads that have not yet been solved in the JIC technology, such as passengers' feet touching their feet and the lack of rigidity of the floor at the tip of the platform.

[Means to solve the problem]

The reason why there is a large gap on the platform facing the curved track is to prevent it from interfering with the running of the vehicle, and after the vehicle has stopped in a fixed position, it is okay to fill the gap with some kind of movable object. The movable object must be removed before the vehicle departs.This condition specifically applies to UJ vehicles that move sideways and approach a vehicle only while the vehicle is stationary at the end of a platform at a railway platform. The movable tread surface has a tread and is installed at an angle so that the movable tread moves upward at the same time as the movable tread moves laterally, and has a related dimension such that when the movable tread moves laterally, the top surface of the movable tread matches or is slightly higher than the top surface of the platform. This solves one problem by eliminating the problem of foot getting stuck due to the step on the platform surface.Furthermore, by arranging the movable treads at an angle, the floor becomes thicker as you move away from the tip of the platform, which naturally improves the rigidity. Furthermore, when using a box-shaped frame to support the movable treads, by providing a vertical rib inside, the rigidity against the load of passengers can be improved by 1j# even on the floor at the tip of the platform, thereby solving the problem. Furthermore, a slit is provided in the movable tread to avoid interference with the vertical ribs during horizontal movement.

[Effect]

With the above-described structure of the present invention, the movable footboard is always in a position where it does not interfere with the running of the vehicle, and the vehicle can arrive at the boarding and alighting area without any problems.

After the vehicle has stopped at a fixed position, the movable footboard moves laterally toward the entrance/exit having a large gap so as to approach the vehicle, thereby filling the gap between the platform and the vehicle. Since the movable treads are arranged at an angle, the movable treads also move upward during lateral movement, eliminating the difference in level between the movable tread surface and the platform surface, allowing passengers to board and alight safely.

Furthermore, by arranging the movable treads at an angle, the floor thickness increases as the distance from the tip of the platform increases, resulting in improved rigidity against passenger loads. In addition, the box-shaped frame that supports the movable footboard is provided with vertical ribs inside, so that sufficient rigidity can be obtained even at the floor at the tip of the platform. Furthermore, since the movable tread plate has a slit at that position so as not to interfere with the rib, the movable tread plate can make the necessary lateral movement.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

Fig. 3 is a plan view of a case where the Bratbohm is provided inside the curved track, and the platform 2 is provided along the trajectory of the central part of the vehicle l, and the bratbohm is provided at the two entrances near the center.
Although there is not a very large gap between the vehicle and the vehicle entrance, there are large gaps at the two entrances near the ends of the vehicle. Here, the movable footboards indicated by 4 and 5 are both moved laterally and are in a protruding position, and the gap G between them and the vehicle is small. - 4' and 5' in dot-dashed lines
All of the movable footboards shown in 2 have returned to their normal positions and are in a retracted state, and are in positions that do not interfere with the running of the vehicle.

Fig. 4 is a plan view of a case where the platform is provided outside the curved track, where the platform 2 is provided along the trajectory of the end of the vehicle l, and the center two of the four entrances are particularly large between the platform and the platform. There is a gap. As in the case of Fig. 3, the movable footboards 7 and 8 move laterally and are in a protruding state, and the gap between them and the vehicle is as small as G, -
The movable footboards shown at 7' and 8° with dashed dotted lines are both in the returned and retracted state and are in positions that do not interfere with the running of the vehicle.

Figure 5 is a plan view of a case where a movable footplate is not provided for each entrance/exit, but one movable footplate is provided for each of the four entrances/exits of one vehicle. 9 is a movable footplate when it moves laterally, and 9' is in its normal position. This shows the state of the movable treadle that has been returned and retracted.

4.4', 5.5', 7.7' in Figures 3 and 4
, 8.8° are shown in FIGS. 1 and 2, respectively.

FIG. 1 is a diagram showing a state in which the movable treadle is moved laterally and extended. Figure 2 shows a state in which the movable footplate has returned to its normal position and is retracted so as not to interfere with the running of the vehicle.The movable footplate 4° can only be positioned below the platform surface 2S, but it is in the state shown in Figure 1. In this case, the movable tread surface 4S is the platform surface 2S.
This is consistent with the above, and prevents tripping caused by steps. (Rising stroke F) is (lateral movement stronic L) 0 Normally, the floor of a vehicle is higher than the platform, and the movable tread is horizontally closer to the vehicle than the platform. Therefore, the heights should be set to match or be higher, taking into account errors. Further, by arranging the movable step board 4 at an angle, the floor thickness increases as the distance from the platform tip increases, thereby improving the rigidity against the passenger's rR weight. Furthermore, since the box-shaped frame 6 that supports the movable footboard is provided with vertical ribs 10 inside, sufficient rigidity can be obtained even at the thin end of the floor. In addition, the movable tread 4 is provided with a slit at the position of the rib so as not to interfere with the vertical rib 10 (see Figures 6 and 7). The movable footboard 4 is supported by a box-shaped frame 6 via a support shaft 12 and linear bearings (such as ball circulating type) 13 and 14. The movable footboard 40 is attached to the member 15. There is an actuator 17 whose one end is connected to the bracket 16 and the other end is connected to the box-shaped frame 6, by which the movable footplate 4 is moved laterally.The movable footplate for the entrance near the center of the vehicle in Fig. 3 is large. Although a stroke is not required, it is advantageous to use the same basic structure as the others, that is, the same inclination angle, and a small stroke.The retracted state at that time is shown as 59 in Fig. 2. Therefore, the lowering of the movable tread surface during storage is also small and the position shown by F' is taken.

FIG. 6 is a perspective view of the entire movable tread device with the movable tread extending out, and is installed on the platform 2 by a flange 6a of a box-shaped frame 6. The movable footboard 4 is shown in a state in which it has been laterally moved outward by a stroke L, and the slit 11 is visible on the top surface. 2S and 48 have the same height.

FIG. 7 is a cross-sectional view showing the arrangement of vertical ribs and other parts within the box-shaped frame 6. There are many vertical ribs 1O supporting the thin outside of the floor.

A support shaft 12 is installed in a small space partitioned by vertical ribs lO.
, actuator 17, etc. are arranged.

FIG. 8 shows another embodiment of the present invention in which the inclination t1 angle of the movable footboard is increased. If the angle is increased, sufficient rigidity can be provided to the tip of the floor, so the box-shaped frame and the vertical ribs inside it are not used. The movable footboard 22 is supported by linear bearings 13 and 14 via the support shaft 12.
．． 14 is directly attached to the back side of the platform 2.

A reaction force receiver for the actuator 17 is also provided on the back surface of the bracket home 2. Increasing the inclination angle is advantageous in terms of the rigidity of the floor, but there is a problem in that it requires a large stroke of the actuator relative to the required lateral movement stroke. In this respect, it is suitable for use when the required lateral movement stroke is not large.

Next, an embodiment will be described in which other inventions related to other elements that improve the safety level of passenger boarding and alighting are combined.

Patent No. 63-255338 [Gateway Door Device for Railroad Vehicles] has a security effect that prevents people from being trapped between the vehicle door and the platform. When there is a large gap between the door and the place where passengers get on and off, a great effect can be obtained by using it in combination with the present invention. An example thereof is shown in a part of FIG. 1B is a partition wall fixedly provided at the boarding and alighting area, and 19 is a boarding and alighting area, and the door 20, which is a structural feature of the invention, is in the bent open state and approaches the vehicle side. Therefore, passengers boarding and alighting are not pushed to the side from the entrance and exit, and do not fall onto the tracks where there are no treads, and even when the door is closed, the bending motion is corrected on the final stroke of the door, and the passengers who are there are not able to get on or off the boarding area. A dotted line 21 indicates the zero-door trajectory that acts to push the vehicle back to the side and prevents it from being trapped between the boarding and alighting place 19 and the vehicle m3.

〔Effect of the invention〕

As described above, the present invention reduces the gap between the vehicle and the platform by using movable treads only when the vehicle is stopped at a fixed position, thereby reducing the gap between the vehicle and the platform on a platform along a curved track. In some cases, the security level for passengers boarding and alighting can be improved, and stations can be unmanned,
To obtain a practical device that can be well adapted to one-man or unmanned vehicles, and also solves problems unresolved with conventional technology, such as passengers' feet being pinched and lack of rigidity of the floor at the end of the platform. be able to.
