Abstract

PURPOSE:To prevent a car from unreasonably passing a railroad crossing by a method wherein a plurality of gates are installed and even when a car unreasonably passes a first gate starting to close, the car is interrupted by a second gate. CONSTITUTION:A plurality of gates 2 for a barrier are installed, and a distance between the gates 2 is a distance long enough for a driver to allow recognition of installation of a plurality of the gates. By interrupting a railroad crossing in an overlapping manner, even when a car unreasonably passes a first gate 2 starting to close, the car is interrupted by a second and following gates 2. Further, a driver is forced to recognize that even when the driver unreasonably passes the first gate, it is interrupted by a next gate, and an effect to give up unreasonable entrance is produced. Further, the number of shafts 5 to transmit a power to a plurality of the gates and other devices, such as a cam, is the same as that of a conventional type and an installation cost is reduced to a low value.

Description

Detailed Description of the Invention

[001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railroad crossing blocking device for ensuring safety at railroad crossings.

[002]

2. Description of the Related Art Conventionally, a single railroad crossing blocking gate has been used as a railroad crossing blocking device. The railroad crossing blocking device is a device for ensuring the safety of traffic and train operations that cross a railroad track.

However, there are many railroad crossing accidents, especially when a railroad crossing blocking device is actuated and the gate for shutting down is approaching.

On the railway side, an alarm device is installed at the railroad crossing, a signboard is used to call attention, and if there is a stuck car inside the railroad crossing, it is detected by the device that stops the train. We are working hard to prevent accidents through the use of devices that display signals or the naked eyes of railway drivers.

However, a device for detecting a stuck car at a railroad crossing cannot detect it unless the car is stopped on the device for a certain period of time or more. It is difficult to ensure safety by operating the brakes with the naked eye detection, and due to the increase in traffic volume to increase the distribution volume, the railway or the speeding up of the car, the crossing accident between the car and the train is Both the number of accidents and the extent of damage are increasing.

[0096]

[Problem to be Solved] Among the drivers of vehicles, a person who enters into a railroad crossing even though one gate for railroad crossing, which is conventionally used as a railroad crossing barrier, is going down, However, it is a fact that when you see a gate going down, some people try to cross the railroad crossing before the train arrives and force you to do so.

At the present time when the transportation network is complicated, there are innumerable places where roads and railroads intersect, and it is best to use an elevated railroad or a tunnel at the railroad crossing to eliminate a railroad crossing accident. It is not possible to install them on all railroad crossings because installation of elevated structures or tunnels requires a lot of cost, and problems such as land will occur.

Therefore, the inventor of the present invention provides a railroad crossing blocking device comprising a plurality of railroad crossing blocking gates which can ensure safety of railroad crossings and can be installed at many railroad crossings at low cost.

[0109]

That is, the present inventor
Multiple gates for railroad crossing are installed at regular intervals,
It is more preferable that opening and closing of the plurality of gates is performed at a gate closer to the railroad crossing slightly earlier or at almost the same time. The device for notifying the opening and closing time or the power for opening and closing may be the same as the conventional one or the number of pieces,
If necessary, supplement and reinforce. Even by using a shaft, a crank, a cam or the like for mechanically transmitting the power to a plurality of gates, the plurality of gates can be opened and closed with the same or a smaller number of power sources as the conventional one, and the present invention can be installed. The cost can be kept low. Further, the material and mechanism of the gate of the present invention may be conventional, but the gate away from the railroad crossing is a material or mechanism that is unlikely to lead to mutual damage even if the gate contacts the car, for example, It is more desirable to use a highly elastic material or a circuit breaker with a safety mechanism that does not lower further when it comes into contact with an obstacle.

According to the present invention, the distance between the gates is 1 of the width of the railroad crossing.
It is more desirable that the distance is / 3 to 1, but it is necessary that the plurality of gates are installed by the driver of the vehicle so that it can be recognized.

What is important in the present invention is that even if the vehicle forcibly passes through the first gate that has begun to be blocked, the vehicle is blocked by the second or subsequent gates and cannot pass through the railroad crossing. It is to be.

[0112]

The effects of the present invention are as follows:
The effect of ensuring the safety of the railroad crossings by physically overlapping the railroad crossings is more effective, but rather
Even if you pass the gate, you will be made aware that the railroad crossing cannot be passed because the railroad crossing will be blocked by the second or later gate
It is possible to block the driver from driving some cars when the gate starts to block, which is an unreasonable attempt to enter the railroad crossing.

The railroad crossing barrier device having a plurality of barrier gates according to the present invention is more effective in improving the safety of railroad crossings where elevated railroads and tunnels cannot be installed in railways that operate at high speed, such as the Yamagata Shinkansen. is there.

Further, when any one of the plurality of gates is in contact with the car, or when the car is stopped between the plurality of gates, an excellent contact sensor can be provided by interlocking with each device and signal. Alternatively, it may be a detection sensor.
