Telescopic evacuation platform stair for subway tunnel interval
The invention discloses a telescopic evacuation platform stair for a subway tunnel interval. The telescopic evacuation platform stair comprises a platform main beam and a telescopic stair body, wherein the platform main beam is fixed below an evacuation platform on the subway tunnel interval side, and sliding grooves serving as sliding rails of the stair body are formed in inner sides of the platform main beam respectively; the telescopic stair body comprises a main stair body and an auxiliary stair body, the main stair body and the auxiliary stair body adopt a mutually reverse buckling structure and can be mutually connected in a relative sliding manner, and one end of each of two side edges of the main stair body is connected with sliding blocks in the corresponding sliding groove through a rotary shaft. The telescopic evacuation platform stair for the subway tunnel interval does not intrude a limit of interval equipment under a normal work condition, does not influence mounting of an interval pipeline and has the advantages of convenience in use, safety, reliability, high evacuation efficiency and the like under a using condition.
