The invention relates to an intelligent vertical shaft braking and buffering system based on a magnetorheological effect and application thereof. The intelligent vertical shaft braking and buffering system comprises a retarder, a buffer, a rotation speed sensor, a pressure sensor, a photoelectric switch and a controller. The retarder is in transmission connection between a hoisting motor and a hoister roller. The buffer is installed on a vertical shaft inner box girder and connected with a tank supporting device. The rotation speed sensor is installed on the hoister roller. The pressure sensoris installed at the bottom of a tank cage. The photoelectric switch is intalled on the side wall of a vertical shaft. The retarder, the buffer, the rotation speed sensor, the pressure sensor and thephotoelectric switch are connected with the controller. The intelligent vertical shaft braking and buffering system is high in intelligence degree; the damping force of the retarder and the buffer canbe adjusted in time accord
