Abstract
The utility model discloses a deviation rectification control device of a large-span gantry crane. The deviation rectification control device of the large-span gantry crane comprises a processor, a position encoder, a deviation rectification position travel switch and a beam calibrating and zero clearing device, wherein a first signal input end of the processor is connected with a signal output end of the position encoder and is used for collecting position information of the position encoder; a second signal input end of the processor is connected with a signal output end of the deviation rectification position travel switch and is used for collecting the position information of the deviation rectification position travel switch; the signal output end of the processor is connected with the signal input end of the beam calibrating and zero clearing device and is used for controlling the beam calibrating and zero clearing device to performing calibrating and zero clearing operations. By collecting the position information of the position encoder and the deviation rectification position travel switch and controlling the calibrating and zero clearing device to work through the processor, an accumulative error is accurately removed, and the running speed of a cart can be easily adjusted after the anti-jamming and high-accuracy requirements are met.
