the device also comprises a plurality of groups of on-line revolving body position detection sensors which are arranged on the frame or on the revolving body and evenly distributed on the circumference according to angles, and are used for detecting whether the revolving body deviates or not;

and a control device for controlling the controlled drive mechanism based on the detection data of the on-line rotary body position detection sensor.

Further, the controlled driving mechanism is an adjustable hydraulic cylinder or an electric mechanism.

In order to achieve the purpose, the circular cooler comprises a circular frame, wherein an inner ring carrier roller group and an outer ring carrier roller group are annularly arranged on the frame on the circular frame; the inner ring carrier roller group and the outer ring carrier roller group are rotatably provided with annular revolving bodies, and are provided with a plurality of groups of online adjustable carrier rollers uniformly distributed on the circumference according to a preset angle, wherein the online adjustable carrier rollers comprise; the carrier roller is arranged on a carrier roller bracket through a rotating shaft, and the carrier roller bracket is arranged on the rack through a slewing bearing; the controlled driving mechanism is arranged on the frame, and the driving end of the controlled driving mechanism is in driving connection with the carrier roller bracket;

the device also comprises a plurality of groups of online revolving body position detection sensors which are arranged on the frame or on the revolving body and are uniformly distributed on the circumference according to angles, and the online revolving body position detection sensors are used for detecting whether the revolving body deviates or not;

In order to achieve the above object, the present invention provides an online aligning method for a circular cooler, the method comprising:

detecting whether the detection data of each online rotator position detection sensor exceeds a preset threshold value in real time;

and if the detection data of one or more online revolving body position detection sensors exceed a preset threshold value, sending a deflection instruction to the online adjustable carrier roller at the corresponding position.

The utility model discloses set up slewer and adjusting device under the cold quick-witted bearing roller base of ring, its signal transmission to master control room PLC when online revolving body position detection sensor detects the solid of revolution and takes place the skew, give bearing roller adjusting device by PLC commander, adjusting device moves and makes the bearing roller take place certain deflection to change the direction of frictional force between bearing roller and the solid of revolution, make the solid of revolution progressively return original position.
