Automatic deviation rectifying device of coal reclaimer

The utility model provides an automatic deviation rectifying device of a coal reclaimer, which belongs to the technical field of reclaiming transportation and comprises a balance bar, a range finder, a variable frequency motor and a controller. The deviation rectifying structure provided by the utility model is stable in function, and can accurately identify and process infrared signals. The flexibility of the balance bar is guaranteed by making the balance bar make rolling contact with the material taking machine, the deflection degree of the swing end of the material taking machine and a box girder is obtained by measuring the distance of a balance point, a PLC automatically adjusts the frequency of a frequency converter according to an automatic deviation rectifying model, the frequency of the frequency converter on the other side is reduced, and the rotating speed of a motor is reduced; the frequency degree of the track frequency converter is adjusted to be in a balance position, the technical effect of u
