である。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railway vehicle (hereinafter referred to as a "vehicle") running on a railway track, even if power is stopped immediately after detecting or notifying an initial sign of occurrence of an earthquake. Using the power obtained by converting the kinetic energy possessed by the electromagnetic coil, a magnetic flux is generated from an electromagnetic coil attached to the vehicle and located just above the line so that leakage of the magnetic flux is reduced, and the electromagnetic coil and the line The present invention relates to a device for generating a suction force during the operation to prevent derailment.

を用いて車両を停車させた。2. Description of the Related Art There are longitudinal waves and transverse waves in an earthquake, and there is a difference in the propagation time. Therefore, an earthquake detector installed appropriately beside the track detects the wave propagating first and detects the wave. The information was transmitted to the vehicle by an electric signal, and the vehicle was stopped using a brake for stopping the vehicle normally.

安定した走行が実現できる。As an example, a weight of 40 tons and a speed of 80
Assuming km / h, the work load Wt of the vehicle is 9.86
x10E6 joules. This value is a very large value. The velocity vector 31 of the kinetic energy is directed in the traveling direction, and smooth and stable traveling can be realized only by receiving a small resistance such as rolling friction from the railway as long as the vehicle is traveling on the railway.
【０００７】従って、走行中に地震の発生を検知した

とが安全確保に有効な手段である。Therefore, if an occurrence of an earthquake is detected during traveling, stopping the vehicle immediately while maintaining the smooth state is an effective means for ensuring safety.

を用いて線路の状態を説明する。FIG. 5 shows the state of the line. 40 is a track, 4
1 is a sleeper, and 42 is gravel laid under the track. FIG.
The state of the line will be described with reference to FIG.

両は線路から大幅に逸脱する恐れがある。[0009] The resistance force while the wheel is traveling on the track 40 is a small rolling friction in the traveling direction. However, once derailed, the sleepers 41 under the tracks are laid perpendicular to the traveling direction of the tracks, and the wheels receive large resistance together with the irregularly laid gravel 42. In spite of the fact that the vehicle has a large kinetic energy, the wheels are subject to great resistance from irregular directions, so that the direction of travel is undefined and the vehicle may deviate significantly from the track.

字型に逸脱した脱線車両の例を示した。FIG. 6 shows how the train derails. As a typical example, if the first vehicle 50 is derailed, the first vehicle 50 will be greatly affected by sleepers and gravel, so that the kinetic energy of the vehicle will be greatly consumed, while it has not been derailed yet Since the rear vehicle still has a large amount of kinetic energy in the traveling direction, it may collide with the front vehicle, increase the departure of the derailed vehicle, and be very likely to derail. In this manner, examples of the derailed vehicles in which the vehicles 50, 51, and 52 deviate in the shape of a square are shown.

る。FIGS. 4 and 5 show states when the vehicle is traveling on a straight line.
As described in 6 above, even while traveling on a curve, the traveling direction is always forced to be tangential to the arc due to the relationship between the track and the wheels, but from a microscopic perspective, the track always exists in the traveling direction. Therefore, the characteristic shown by a straight line can be similarly applied to a curve.

45. In a railway vehicle derailment prevention device using electromagnetic force, a technology for receiving power from a power supply line, operating an electromagnet device, and generating an attractive force between the vehicle and a track to prevent derailment has been disclosed. . However, since it is assumed that the power is supplied from the power supply line and the operation is performed, it is impossible to operate due to the stop of the power supply line during an earthquake, or even if the power is supplied, due to the earthquake vibration. If the power collector cannot receive power from the feeder line, a serious malfunction period will occur between 10 seconds and 20 seconds required for stopping, even if the generation period is short, so everything that can be used for earthquake resistance Although it is required to operate reliably even in a state where it cannot be used, the principle of using a normal power supply cannot be expected to be effective for earthquake resistance.

However, there was a possibility that derailment could occur due to the above, but there was a problem that there was no special method to prevent derailment other than stopping the vehicle with a normal brake in all conditions.
