Abstract

The utility model discloses an emergency entrance device for a railway vehicle door system, which mainly comprises a panel, a bracket, a baffle plate, a rotating shaft, a cable quadrant, a spring, a cylindrical pin, a cam, a square board and a positioning disc. In the utility model, the ratchet wheel principle is applied to the emergency entrance device; and the emergency entrance device is reliable to position. When the emergency entrance device is in an unlocked state, the baffle plate is clamped in a groove of the square board, and a bead positioned on the bracket is also clamped in the groove of the positioning disc at the same time, so that a steel wire rope is effectively prevented from driving the cable quadrant to invert and the entrance device is reliably positioned; and when the emergency entrance device is restored, the rotating shaft is reversely operated to prevent the baffle plate from restoring the friction force of the cam. In case of emergency, a rescue worker can provide a safe and reliable rescue channel by operating the device.
