Tower crane lifting hook anti-swing control system

Abstract

The invention discloses a tower crane lifting hook anti-swing control system which comprises a control device and a detection device, wherein the control device and the detection device are connectedthrough a CAN bus; the control device comprises a linkage table and a PLC, the linkage table is used for giving an anti-swing starting operation signal, and the PLC is used for receiving a control signal and sending an operation control command; the detection device comprises a variable-amplitude encoder installed on a variable-amplitude trolley and an angle sensor installed on a lifting hook, thevariable-amplitude encoder is used for detecting the displacement of the variable-amplitude trolley in real time, and the angle sensor is used for detecting the dangling angle of the lifting hook inreal time; and data detected by the variable-amplitude encoder and the angle sensor in real time are sent to the PLC through the CAN bus, the PLC calculates the corresponding variation through a corresponding relation model algorithm, then outputs a corresponding control signal to control the operating speed of a variable-amplitude motor, and therefore, swing of the lifting hook is reduced in realtime. According to the tower crane lifting hook anti-swing control system, swinging of the lifting hook in the operation process can be effectively eliminated, and the automation degree is high.

Description

technical field [0001] The invention relates to the technical field of tower cranes, in particular to a tower crane hook anti-swing control system. Background technique [0002] When the hook of the tower crane lifts an object and runs under the driving of the trolley, sometimes the hook will sway due to the wind or the inertia when it reaches the placement point, which will make the crane driver It is difficult to control, and there is a serious danger of the lifting object falling. Simply relying on the operating experience of the crane driver to eliminate the swing of the hook is not only labor-intensive, but also has poor control accuracy and low efficiency, which is far from meeting the needs of modern production and transportation. Contents of the invention [0003] The purpose of the present invention is to provide a tower crane hook anti-swing control system, which can eliminate the swing of the hook through automatic control, thereby improving the delivery accura...
