Description

  The present invention relates to a train accident prevention apparatus for preventing a train accident in a train, and more specifically, not only rescues an intruder who has entered a track, but also a person caught between tracks Also, the present invention relates to an accident prevention device for a train that makes it possible for a person lying on the side of a track to be rescued.

  In recent years, personal accidents due to jumping into the railway track, dropping, etc. have frequently occurred, and the amount of work such as restoration due to this has increased. In this regard, an automatic train stop device (“ATS”) has conventionally existed as a device for keeping train operation safe, but this ATS automatically activates a brake in an emergency. It cannot effectively handle personal accidents that require urgency, such as jumping up or falling.

For this reason, in the past, various devices have been proposed as rescuers for those who jumped on the track. For example, in Japanese Patent Application Laid-Open No. 2001-10495 “Train injury prevention device”, an accident target person is received from the front. For this purpose, there is provided a front bag for supporting the accident subject from the bottom, which is connected to the lower surface of the front bag, and is located in front of the front end in the train traveling direction. As a result, a person who has entered the track is picked up and received, and it is possible to deal with personal injury.

  By the way, in the conventional accident prevention device described above, the main purpose is to scoop up all the people who have entered the track, but if you try to scoop up all the people who have entered the track, There is a possibility that dangerous cases may occur.

  That is, the above-described conventional accident prevention device is provided with a guide plate for scooping up the intruder, but this guide plate must be placed at least on the upper side of the sleeper to enable the train to travel. It must be in a passable position. To that end, for example, between those who are lying between the tracks in the direction of the train and with their heads lying on the running train, or in the same direction and in the direction of the train Assuming those who are lying on the side of the track with their heads facing, they must crawl up from below the head to ensure that they crawl up. If it is, the guide plate cannot be put under the head, and it is considered that the guide plate hits a part of the head and keeps pushing the intruder as it is. It becomes impossible to rescue intruders.

  Accordingly, an object of the present invention is to provide a train accident prevention apparatus that can reliably rescue all persons who have entered the track.
