Locking adjusting device, continuous casting machine and locking adjusting method

The embodiment of the invention provides a locking adjusting device, a continuous casting machine and a locking adjusting method, and relates to the field of steel production. The locking adjusting device comprises a stopping piece, a supporting piece and a driving piece. Wherein the stopping piece is used for braking a rotating shaft of the continuous casting machine, the supporting piece is connected to the stopping piece, and the driving piece is connected to the supporting piece and drives the stopping piece to move through the supporting piece. According to the locking adjusting device, a power source can be provided through the driving piece, and the stopping piece is driven to move through the supporting piece, so that the stopping piece brakes the rotating shaft of the continuous casting machine, locking adjusting operation is achieved, the braking safety of the rotating shaft of the continuous casting machine is improved, and potential safety hazards are reduced. The continuous casting machine compri
