Abstract

The invention discloses a hoisting load anti-swing control device, method, system and engineering machinery. The hoisting load is hoisted by a cantilever crane through a lifting rope. The hoisting load anti-swing control device comprises a receiving device and a control device, wherein the receiving device is used for receiving the horizontal position of the top end of the cantilever crane and / or receiving the tilt angel of the hoisting load and the rate of the tilt angle; the control device is used for carrying out one of the followings: when the horizontal position of the top end changes, controlling an anti-swing device to compensate the horizontal displacement of part of the lifting rope so as to enable the horizontal position not to change before the horizontal position of the top end of the cantilever crane changes; when the tilt angle and rate of the tilt angle of the hoisting load are greater than the preset values, adopting fuzzy PID control algorithms to enable the anti-swing device to control the horizontal displacement of part of the lifting rope so as to restrain the tilt angle and the rate of the tilt angle. Through the adoption of the technical scheme, various interferences can be counteracted, greater swing can be restrained, and higher positioning precision can be reached.

Description

technical field [0001] The present invention relates to engineering machinery, in particular to a hoisting anti-sway control device, a hoisting anti-sway control method, a hoisting anti-sway system, and an engineering machine including the system. Background technique [0002] During the hoisting process of the hoisting machinery, due to reasons such as boom rotation, pitching and wind load, the hoisting weight will sway obviously. When the swing range is large, on the one hand, it is not conducive to the rapid and stable completion of the hoisting task, which affects work efficiency; safety hazard. [0003] The existing anti-sway devices are mainly passive anti-sway, or the active control ability is low, and the anti-sway ability to interference is also low. Contents of the invention [0004] The object of the present invention is to provide a hoisting anti-sway control device, a hoisting anti-sway control method, a hoisting anti-sway system, and construction machinery ...
