Wherein, the inclination angle value and the suspension interval value respectively correspond to independent error range values, and when the inclination angle value is in the corresponding error range, whether the inclination angle value of the suspension magnet 4 meets the preset inclination angle requirement or not; when the suspension interval value is within a corresponding error range (for example, 0.1 mm), the suspension interval value meets the preset interval requirement; if there are detection amounts not within the corresponding error range, the levitation magnet 4 is not substantially maintained in the preset smooth state, and the levitation magnet 4 is adjusted again according to the preset rule, so that the adjustment reliability can be improved.
When the control method is applied to the adjusting device, the control process can be realized through the controller 51, and the working principle comprises the following steps: the temperature detection device 57 detects the temperature value of the track beam 2 at the set position in real time, and transmits the temperature value to the controller 51 through the wireless sensor network, the controller 51 stores a database of deformation caused by bridge temperature gradient, and the vertical deformation and the horizontal inclination value of the detection point on the track beam 2 are automatically searched according to the database. The controller 51 controls the oil delivery amount or oil extraction amount of the hydraulic tank 31, the telescopic column 32 can be lifted, oil leakage cannot occur in the lifting process due to the existence of sealing rubber, the suspension gap value and the inclination angle value of the suspension magnet 4 and the track beam 2 can be changed, and the suspension magnet 4 can return to a smooth state when the track beam 2 is not deformed.
When the hydraulic tank 31 is adjusted for the first time, the angle detection device 55 detects the horizontal inclination angle value of the levitation magnet 4 at the moment, the interval detection device 56 detects the levitation gap value at the moment, the levitation gap value is transmitted to the controller 51 through the wireless sensor network, the controller 51 carries out error estimation on the horizontal inclination angle and the vertical deformation of the detection point of the track beam 2 according to the detected inclination angle value and levitation gap value, if the error meets the requirement, the adjustment process is finished, if the error does not meet the requirement, the controller 51 can control the hydraulic tank 31 to work again, the above process is repeated until the measurement result error calculated by the controller 51 meets the requirement, and the adjustment process is finished.
