The coke can is placed on the rotating table device. When the carrier carries the coke can and is in the coke oven area to receive red coke, the control system commands the rotating table to drive the coke can to rotate. After receiving the red coke, the rotating table stops rotating at the specified position under the command of the control system, and then the carrier carries the coke can to the bottom of the dry coke quenching elevator. After arriving under the elevator, the elevator lifts the coke can according to the command.

[0003] At present, the rotating platform device of the coke tank carrier is mainly composed of a motor, a reducer, a rotating arm and a rotating platform. When working, the motor drives the reducer through a coupling, the output shaft of the reducer is connected to the rotating arm, and the rotating arm drives the rotating platform, so that the coke tank on the rotating platform can rotate. In the existing design, when unexpected situations such as power failure, motor failure, and failure of the inverter controlling the rotating motor occur, the coke tank will not stop at the specified position, causing a major accident when the elevator lifts the coke tank.
