Method and device for adjusting and controlling lifting performance of lifting machine

Abstract

The invention discloses a method and device for adjusting and controlling the lifting performance of a lifting machine. The method comprises the steps of acquiring an actually measured basis wind load of the lifting machine; determining load adjustment coefficients of the lifting machine according to a preset first reference wind load, a preset second reference wind load and the actually measured basis wind load; determining an actually measured lifting performance curve corresponding to the actually measured basis wind load according to a first lifting performance curve corresponding to the first reference wind load and a second lifting performance curve corresponding to the second reference wind load as well as the determined load adjustment coefficients; controlling the lifting performance of the lifting machine according to the actually measured lifting performance curve. By adopting the method and the device, the lifting performance of the lifting machine can be adaptively adjusted according to the actually measured wind load to reach the best performance state.

Description

technical field [0001] The invention relates to the technical field of engineering machinery control, in particular to a method and device for adjusting and controlling the hoisting performance of a hoisting machine. Background technique [0002] In the field of hoisting machinery technology, the hoisting performance of hoisting machinery such as boom tower cranes is an important performance index in the work of hoisting machinery. The hoisting performance of cranes is affected by various external conditions such as wind load. Therefore, how to adjust and control the hoisting performance of the hoisting machinery to achieve an optimal state is very important to ensure safety and maximize the potential of the hoisting machinery. [0003] At present, lifting machinery such as luffing jib tower cranes generally realize the control of lifting performance through a predetermined lifting performance curve. Although the lifting performance curves of different luffing jib tower cran...
