SUMMARY OF THE INVENTION The above conventional circuit breaker has a structure in which a pedestrian or a driver of a normal vehicle having a low vehicle height can easily see a breaking rod, and the breaker can be surely prevented from entering these railroad crossings. I could do it. However, if the driver of a large vehicle such as a truck is not well visible and it is difficult to hear the warning sound indicating the operation of the circuit breaker due to ambient noise, etc., it is determined that the circuit breaker is operating. There was a risk that a large car would push the shut-off rod and enter the railroad crossing without the driver's knowledge.

[0004] For this reason, when such bad conditions overlap, it is not possible to say that there is no danger of a trouble hindering the progress of the train or an accident colliding with the train. Also, if a truck is forcibly intruded, even if a collision accident does not occur at that time, the breaking rod will be broken and this recovery will be costly and troublesome, and the railroad crossing will not be closed and unsafe There was a problem of becoming a state.

The present invention has been made in view of the above-mentioned problems of the prior art. The driver of a large vehicle is informed that the circuit breaker is in operation, and the vehicle is crossed. It is an object of the present invention to provide a boom-type circuit breaker capable of surely stopping the intrusion of a sword.

[0006]

The gist of the present invention to achieve the above object is to set aside a traversing road, and to lay a brace-type breaking rod approximately horizontally in a direction crossing the traversing road. A stand which is installed on the side of the crossing and a pair of breaker bodies (33, 13) attached to the stand (12). A normal position breaking rod (36) which falls to a normal low position for effectively stopping the passage of a pedestrian or a normal vehicle is attached to one of the pair of circuit breaker bodies (33, 13). And a high position breaking rod (16) which falls to a high position where a driver of a large vehicle such as a truck is easy to see is attached to the other of the pair of breaking machine bodies (33, 13). Shasha It resides in the machine.

[0007]

According to the present invention, the crossing bar can be turned upside down and the crossing can be temporarily closed at the time of passing a train, etc. A normal position breaking rod (36) that falls to a normal low position that effectively stops traffic such as a vehicle, and a high position breaking rod (16) that falls to a high position that is easy for a driver of a large vehicle such as a truck to see.
Are provided, so that when operated, these blocking rods cross the traversal road side by side at their respective heights.

For this reason, the normal position interrupting rod (36)
As a result, the intrusion of passers-by and ordinary vehicles is reliably prevented as before, while the high-position blocking rod (16) informs the driver of the large-sized vehicle that the circuit-breaking machine is in operation, thereby invading the large-sized vehicle. Can also be reliably prevented.
