Abstract

The invention provides a built-in crane anti-sway control system. The system comprises a crane, the crane is formed by a main lifting motor, an auxiliary lifting motor, a cargo motor and a trolley motor, the main lifting motor is provided with a main lifting frequency converter, the auxiliary lifting motor is provided with an auxiliary lifting frequency converter, the cargo motor is provided with a cargo frequency converter, and the trolley motor is provided with a trolley frequency converter; the main lifting frequency converter, the auxiliary lifting frequency converter, the cargo frequency converter and the trolley frequency converter communicate with and are connected to a built-in sway controller through a CAN bus; the main lifting frequency converter, the auxiliary lifting frequency converter, the cargo frequency converter and the trolley frequency converter are respectively connected to an electric appliance controller through wires, and the electric appliance controller is connected to an operating platform; and the operating platform transmits a signal to the built-in sway controller. The anti-sway control system calculates the running speeds of the cargo and the trolley of the sway eliminated crane through the built-in anti-swing controller according to an operating instruction and the real-time running condition of the crane in order to accurately eliminate the load sway phenomenon of the crane.

Description

technical field [0001] The invention relates to the technical field of crane control, in particular to a built-in crane anti-sway control system. Background technique [0002] Industrial cranes are hoisting equipment that are horizontally placed over workshops, warehouses and stockyards for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is a kind of hoisting machinery with the widest range and the largest number. [0003] When a crane is used to move materials, the movements of the crane's cart, trolley and hoisting mechanism are usually independently controlled by their respective operating commands. When the transported material reaches the target position, d...
