The invention relates to a self-lifting subway tunnel escape platform which effectively solves the problems that a platform is submerged by water and oxygen in a tunnel is insufficient. According to the technical scheme, the tunnel supporting device comprises a plurality of sets of vertical supporting rods which are evenly distributed in the length direction of a tunnel body, and each set of supporting rods comprises a plurality of supporting rods; a flat plate is arranged on each group of supporting rods, and a plurality of sleeves are fixed on each flat plate; the plurality of sleeves are in one-to-one correspondence with the plurality of supporting rods; the sleeve can move up and down along the supporting rods, and a plurality of annular grooves are evenly distributed in each supporting rod in the length direction of the supporting rod; a water tank is fixed on the sleeve; a locking mechanism corresponding to the annular groove is arranged on the water tank; the locking mechanism comprises an elastic pin hinged to the upper end of the water tank; a positioning rod is arranged on the pin, a limiting rod is arranged on the water tank, and the limiting rod can block the positioning rod, so that the elastic pin is kept in a horizontal state and does not rotate; after the limiting rod is reset, the inclined face end of the elastic pin can swing upwards, and the height of the platform can be automatically increased.

    本发明涉及一种自升降地铁隧道逃生平台,有效解决平台被水淹没,以及隧道内氧气不足的问题;其解决的技术方案是包括沿隧道本体长度方向均布的多组竖直的支撑杆,每组支撑杆内均包含多个支撑杆;每组支撑杆上均设置有一个平板,每个平板上固定有多个套筒;多个套筒与多个支撑杆一一对应;套筒能沿支撑杆上下移动,每个支撑杆沿其长度方向均布有多个环形凹槽;套筒上固定有水箱;水箱上设置有环形凹槽对应的锁止机构;锁止机构包括铰接在水箱上端的弹性销钉;销钉上设置有定位杆,水箱上设置有限位杆,限位杆能阻挡定位杆,使弹性销钉保持水平状态不旋转;限位杆复位后,弹性销钉的斜面端能向上摆动,本发明能自动提升平台的高度。
