[0007] 2. The power of the driving wheels of the trolley is inconsistent, causing the trolley to tilt
However, in actual operation, with the acceleration of the running speed of the trolley, the traditional mechanical method cannot avoid the deviation of the trolley running mechanism, and the correction of the horizontal wheel of the trolley may easily cause excessive lateral force and cause track damage, and the working state of the trolley running mechanism is unstable. It is also the main cause of rail rubbing and rail gnawing during on-site operations

The patent of the present invention discloses a deviation correction method for a double-girder crane trolley, which includes the following steps: detecting the running state of the double-girder crane trolley to obtain position information; according to the position information, obtaining the deviation of the double-girder crane trolley information; according to the offset information, the sliding mode variable control algorithm is used to correct the deviation of the double-girder crane trolley. The present invention obtains the position information of the pulley of the trolley by detecting the running state of the trolley of the double-girder crane; according to the position information, the deviation degree information of the trolley of the double-girder crane is calculated; according to the information of the deviation degree, the sliding mode variable The control algorithm corrects the deviation of the double-girder crane trolley. Through the above technical proposal, the present invention realizes the stable deviation correction of the double-girder crane trolley, effectively reduces the wear between the double-girder crane trolley and the running track, and further improves the service life of the double-girder crane trolley.
Description
technical field [0001] The patent of the invention relates to the application field of double-girder cranes, in particular to a deviation-correcting method for a double-girder crane trolley. Background technique [0002] Double-girder cranes generally refer to double-girder bridge cranes. Double-girder bridge cranes are important tools and equipment for mechanization and automation of the production process in modern industrial production and lifting transportation. Therefore, double-girder bridge cranes are widely used in indoor and outdoor industrial and mining enterprises, It is widely used in iron and steel chemical industry, railway transportation, port terminals and logistics turnover and other departments and places. [0003] Double-girder cranes are generally composed of three major parts: mechanical, electrical and metal structures. Among them, the mechanical part is divided into lifting mechanism, trolley running mechanism and cart running mechanism. The lifting m...
