The invention discloses an overhead travelling crane longitudinal cart electromagnetic driving type travelling system, and belongs to the technical field of crane control. The overhead travelling crane longitudinal cart electromagnetic driving type travelling system comprises a travelling control system for a travelling cart. The travelling control system comprises a processor, a current path control unit and a current commutator assembly. The processor is connected with a power supply circuit through the current path control unit. The power supply circuit is provided with a plurality of current commutators. The output end of each current commutator is provided with an execution coil or a driving coil. Each current commutator is correspondingly provided with a current monitor. Each drivingcoil is provided with an inductor. The processor comprises a clock unit, a storage unit and a data collecting and analyzing unit. The current path control unit comprises a trial implementation unit and a converter module. The trial implementation unit is used for measuring the resistance before starting of the cart. The converter module is used for controlling power supply current. The crane longitudinal cart electromagnetic driving type travelling system is used for controlling the execution / driving coil on a cross beam or the travelling cart through following-up of current, and guarantees stable traveling of the cart.
Description
technical field [0001] The invention belongs to the technical field of hoisting machinery control, and in particular relates to an electromagnetically driven driving system for a longitudinal trolley of a hoisting vehicle. Background technique [0002] At present, bridge cranes play a very important role in the national economy as lifting equipment for material lifting. The traditional bridge crane control system uses relay control and rotor circuit series resistance to realize the speed regulation of the bridge crane. Frequent starting, braking, forward and reverse, speed change, etc., this kind of control will have an impact on its equipment and production efficiency and even involve personal safety, and when the motor is used to start the trolley, frequent vibrations will have The adaptation life of the device is affected. Contents of the invention [0003] The purpose of the present invention is to provide an electromagnetic drive driving system for the longitudinal ...
