Tower crane, and anti-swing controlling method, device and system of lifting hook of the tower crane

Abstract

The invention discloses a tower crane, and an anti-swing controlling method, a device and a system for a lifting hook of the tower crane. The anti-swing controlling method for the lifting hook includes: acquiring present operation status parameters of the lifting hook in real time during the operation condition of the lifting hook; and when receiving a command of stopping the lifting hook operation, acquiring rotation control parameters and amplitude variation control parameters according to the acquired operation status parameters at present and a preset control role, and controlling a rotation mechanism and an amplitude variation mechanism of the tower cane to be operated reversely to the rotation control parameters and the amplitude variation control parameters, so as to reduce the horizontal shift between the lifting hook and a rotating arm support of the tower cane. Through the technical scheme, swing control of the lifting hook in the rotation direction and the amplitude variation direction can be achieved so that the tower cane can be operated stably, accidents caused by collision caused by swing of a lifted object are reduced, the working safety is improved and the working efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a tower crane and a hook anti-sway control method thereof, an anti-sway control device and an anti-sway control system. Background technique [0002] At present, in the field of hoisting machinery, such as tower cranes (tower cranes), during the deceleration and stop operation process, there is a phenomenon that the hook and the slewing arm frame deviate, that is, affected by the acceleration of the tower crane, the hook still continues when the stop command is issued. Slow down the operation, so that the hook and the slewing arm will meet sideways, causing the hook to swing and the hanging object to be difficult to place, which seriously affects the operation safety and work efficiency. [0003] There are not many anti-sway control technologies for tower cranes in the prior art, such as figure 1 Shown is a typical active frequency conversion anti-sway system. The ac...

Problems solved by technology

[0004] However, this active frequency conversion anti-sway method relies on the anti-sway reel and frequency converter to achieve anti-sway, and the anti-sway effect of this method is not obvious in the actual use process
