Hook motion control mechanism and tower crane

Abstract

The invention provides a hook motion control mechanism for a tower crane. The tower crane comprises a boom, a hook suspended on the boom and used for hosting a heavy object, a slewing mechanism, a hoisting mechanism and an amplitude changing mechanism, wherein the slewing mechanism, the hoisting mechanism and the amplitude changing mechanism are respectively used for driving the boom to rotate, drive the hook to lift and drive the hook to change the amplitude; the hook motion control mechanism comprises an information acquisition device, a processor and a controller, wherein the information acquisition device is used for acquiring the motion state information of the hook of the tower crane in real time when an information acquisition instruction of an operator is received; the processor is used for generating a preset motion locus of the hook according to the motion state information; and the controller is used for controlling the hook to move along the preset motion locus when a starting instruction of the operator is received. Through the system, the control accuracy of the hook can be effectively improved, the operating efficiency is improved, and the labor intensity of the operator is reduced.

Description

technical field [0001] The invention relates to the field of hoisting machinery, in particular to a hook motion control system and a tower crane. Background technique [0002] In the existing tower crane operation, the positioning of the hook depends entirely on the experience of the driver. During the operation, the angle of rotation is too large or too small, the lifting is too high or too low, and the amplitude is too large or too small. Effectively move the hook to the target position. Especially in the working condition that the hook frequently runs repeatedly with the same trajectory between two fixed positions, it cannot move to the target position quickly and effectively, which affects the work efficiency, and at the same time, the labor intensity of the operator is high. [0003] Therefore, a new hook control technology is needed, which can effectively improve the control accuracy of the hook, improve work efficiency, and reduce the labor intensity of operators. ...
