Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rail transportation, in particular to an intelligent anti-fall safety device for rail transportation. Background Art
[0002] Rail transit refers to a type of transportation vehicle or transportation system in which operating vehicles need to travel on specific tracks. These systems are usually powered by electricity and operate in a wheel-rail manner. They are a general term for fast, large-capacity public transportation.
[0003] When waiting on some train or subway platforms, there is a great distance difference between the platform and the track, so passengers waiting for the train are often in danger of falling off the platform. With the advancement of technology, for subways, due to their short length, corresponding fences are designed for subway platforms to separate the track from the platform. However, for train platforms, the trains are long and most of the waiting platforms are located in the open air. It is costly and difficult to design a wrapping fence similar to the ground-falling type. In most cases, the only way to warn passengers to pay attention to safety is through the reminders of the track staff, but this method has great limitations and is not safe enough.
[0004] Therefore, in view of the above-mentioned problems, the present technical solution proposes an intelligent anti-fall safety device for rail transit. Utility Model Content
[0005] The purpose of the utility model is to provide an intelligent anti-fall safety device for rail transit to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an intelligent anti-fall safety device for rail transit, comprising a plurality of continuously distributed anti-fall components installed on the side wall of the platform facing the direction of the rail vehicle, the anti-fall components are installed in a lifting manner along the side wall of the platform, and play a blocking and protection role when raised, and are used for walking through when lowered. The anti-fall components include a fence box distributed along the outer wall of the platform and the top of the fence box is consistent with the height of the top of the platform. A fence is installed in a lifting manner inside the fence box to adjust the staying height of the fence to play a blocking and protection function. Mounting rods are installed at both ends of the top of the fence box extending toward the top of the platform, and the ends of the mounting rods are connected to mounting columns detachably installed on the platform. The installation and removal of the anti-fall components and the platform are controlled by the detachable connection between the mounting columns and the platform. At the same time, a rescue rope box is provided on the mounting column, and the rescue rope box is used to provide quick rescue measures for passengers who fall into the track, thereby further increasing the safety protection capability of the device.
[0007] Compared with the prior art, the beneficial effects of the utility model are: by adopting a detachable installation method, the anti-fall components are continuously distributed along the length of the platform, and the automatic lifting function of the fence is utilized to provide passengers with safe and intelligent protection capabilities. At the same time, the installation and use costs are low. When facing a long-distance platform, it can still be used for rapid response. In conjunction with the rescue rope set on the mounting column, the subsequent rescue capability of the device is further improved, and the overall safety protection strength is raised.
