Description

  The present invention relates to a train rollover prevention device for a bridge caused by a strong wind, which prevents a derailment rollover accident of a vehicle traveling on the bridge during a strong wind.

  In recent years, there have been many disasters caused by abnormal weather. In particular, strong wind disasters such as tornadoes are seen, and it is an urgent need to prevent derailment overturning accidents of vehicles traveling on bridges and suspension bridges.

Conventionally, a technique for preventing a fall accident of a traveling vehicle during an earthquake is disclosed in Patent Document 1 below. This is configured such that side walls for preventing vehicle overturning are arranged on both lower surfaces of the vehicle.
JP-A-2005-76392

  However, the above-described vehicle overturning prevention side wall is exclusively a measure against an earthquake, and is arranged on both lower sides of the vehicle. In particular, it is not designed as a measure against strong winds at bridges.

  In view of the above situation, the present invention provides an apparatus for preventing train rollover in a bridge caused by strong winds by arranging a rail extending in a traveling direction on an oblique or vertical member of a bridge corresponding to the eaves of a railway vehicle. For the purpose.

In order to achieve the above object, the present invention provides
[1] In a train rollover prevention device for bridges caused by strong winds, a train rollover prevention rail that extends in the direction of travel is placed above the diagonal or vertical material of the bridge corresponding to the eaves of railcars. It is characterized by preventing.

  [2] In the train rollover prevention device for a bridge by a strong wind as described in [1] above, the rails are arranged on both sides of a train travel path.

  [3] In the train rollover prevention device for a bridge caused by a strong wind as described in [1] above, when an upline and a downline are provided, the rails for the upline and the downline are arranged on the diagonal material or the vertical material at the center of the bridge. It is characterized by doing.

  According to the present invention, it is possible to prevent the train from being overturned in the bridge due to strong winds by arranging the rail extending in the traveling direction on the diagonal or vertical member of the bridge corresponding to the eaves of the railway vehicle.

  The train rollover prevention device by a strong wind according to the present invention arranges a rail extending in the traveling direction above the diagonal or vertical material of a bridge corresponding to the eaves of a rail vehicle, thereby preventing the train from being flipped during a strong wind.

  Hereinafter, embodiments of the present invention will be described in detail.

  FIG. 1 is a schematic diagram of a bridge provided with a train rollover prevention device according to the present invention, FIG. 2 is an explanatory diagram of the train rollover prevention device according to the present invention and train travel, and FIG. FIG. 2 (b) is a diagram showing the running state of the vehicle during strong winds in the bridge, and FIG. 3 is a schematic diagram of the truss bridge.

  In these drawings, 1 is a bridge, 2 is a diagonal or vertical member of the bridge 1, 3 is a rail for preventing train rollover arranged in the traveling direction on the diagonal or vertical member 2, 4 is a track of the train, 5 is a train body, 6 is a train body 5, and 7 is a train wheel.

  A derailment capsizing accident may occur when a vehicle traveling on a bridge in a strong wind receives a large lateral aerodynamic force.

  As shown in FIG. 2A, the vehicle when the strong wind is not blowing on the bridge can travel without any problem. However, when the wind is strong in the bridge, the vehicle is blown toward the leeward side under the wind pressure, but the eaves 6 of the vehicle body 5 are placed on the rail 3 for preventing the train rollover disposed on the diagonal member or the vertical member 2 of the bridge 1. The contact will prevent the train from being overturned.

  In particular, the vehicle body 5 can come into contact with the train rollover prevention rail 3 at an angle that is not greatly inclined, so that the impact on the train rollover prevention rail 3 does not have to be large. In some cases, the vehicle body 5 can be automatically returned to the normal posture.

  FIG. 4 is a view (No. 1) showing a bridge provided with a train rollover prevention device by a strong wind according to the present invention.

  In FIG. 4, 11 is a bridge, 12 is an oblique or vertical member on the right side of the bridge 11, 13 is a rail roll-up prevention rail arranged in the traveling direction on the right diagonal or vertical member 12, and 14 is a track of a train ( Rail), 15 is a train body, 16 is a train body, 17 is a train wheel, 18 is a diagonal or vertical member on the left side of the bridge 11, and 19 is a diagonal or vertical member 18 on the left side. This is a rail for preventing train rollover arranged in the direction.

  In this way, by arranging the train rollover prevention rails 13 and 19 on both sides in the traveling direction of the train, the train rollover prevention rail 13 can be used when the train body 15 is beaten regardless of the direction of the strong wind. By touching 19, it is possible to prevent the train from overturning.

  In particular, according to the present invention, when a railway vehicle that has received a crosswind derails on a bridge, the vehicle body is prevented from being overturned so that a large displacement of the vehicle body does not occur.

  FIG. 5 is a diagram (No. 2) showing a bridge provided with a train rollover prevention device by strong wind according to the present invention. In this example, the diagonal material of the bridge 23 installed between the up line 21 and the down line 22 or The vertical member 24 is shared, and the train rollover prevention rail 25 for the up line 21 and the train rollover prevention rail 26 for the down line 22 are arranged on both sides of the diagonal member of the bridge 27 or the vertical member 28. Is. By comprising in this way, arrangement | positioning of the rails for train rollover prevention can be made easy.

  FIG. 6 is a diagram showing an example in which the train rollover prevention device using strong wind according to the present invention is applied to a truss structure bridge.

  In this figure, rail rollover prevention rails 33 are arranged on the left and right diagonal members or vertical members 32 of a truss-structured bridge 31 in the traveling direction of the train.

  As described above, the rails for preventing train rollover on the upper part of the diagonal materials or vertical members of the bridge corresponding to the eaves of the train body can be used to derail overturning trains that pass through bridges that are prone to strong winds. Can be prevented.

  The assumed application location is generally applicable to bridges, but in long bridges such as suspension bridges where large wind loads cannot be taken, the section is particularly susceptible to large wind pressures. The present invention is particularly effective because it does not receive a large wind load unlike a fence or a windbreak wall.

FIG. 7A is a parallel string truss bridge, FIG. 7B is a curved truss bridge, and FIG. 7C is a Warren truss bridge. 7 (d) shows the Hautrus bridge, FIG. 7 (e) shows the Pratt truss bridge, FIG. 7 (f) shows the upper truss bridge, and FIG. 7 (g) shows the lower truss bridge.

  In these bridges, 41 is a diagonal member and 42 is a vertical member. In these bridges, the train rollover prevention rails 43 are arranged in the horizontal direction of the diagonal members 41 or the vertical members 42, that is, in the traveling direction of the vehicle.

  In addition, this invention is not limited to the said Example, Based on the meaning of this invention, a various deformation | transformation is possible and these are not excluded from the scope of the present invention.
