Description

Technical Field

[0001] The utility model relates to the field of reinforcement of evacuation platforms in subway operation tunnels, and particularly designs a detachable evacuation platform reinforcement device for subway operation tunnels. Technical Background

[0002] The evacuation platform refers to a special passage set in the subway interval tunnel for evacuating passengers. The height of the evacuation platform is generally the same as that of the station platform. In case of an accident, the car door can be immediately opened to prevent passengers from evacuating from the evacuation platform to the nearest station. During the operation of the subway, if an accident occurs in the tunnel, after the train stops steadily, passengers can get off the carriage and reach the evacuation platform, quickly leave the accident site, and safely reach the station or the safety exit, thus ensuring the safety of passengers; if an accident occurs on the platform, passengers can get off the evacuation platform through the evacuation door of the train cab and leave quickly.

[0003] With the rapid development of urban rail transit, the continuous opening and operation of operation lines, and the gradual increase in the task of treating structural diseases in operation tunnels. During the maintenance construction of tunnels, the loosening and displacement of the evacuation platform are one of the common diseases in subway operation tunnels. The harm caused by the displacement of the above-mentioned evacuation platform is relatively serious. The loosening and sliding of the evacuation platform may cause harm to the construction and maintenance personnel in the operation tunnel. In severe cases, it may scratch the train or cause the train to brake, causing accidental injuries to the people on the train and having a great social impact.

[0004] The traditional evacuation platform reinforcement process is to replace the pin between the evacuation platform and the evacuation platform support. When the evacuation platform fixing device is damaged, the evacuation platform is replaced to solve the displacement of the evacuation platform. The traditional process of replacing the pin cannot completely solve the risk of evacuation platform displacement. As the train runs, the pin of the evacuation platform may fall off again. At the same time, when replacing the evacuation platform, because the tunnel has been opened and operated, the skylight time is short, and the evacuation platform is large in volume, it is time-consuming to carry, has a high safety risk, and the cost of replacing the evacuation platform is relatively high.
