Abstract

The invention provides a crane control method and system and a crane. According to the method, a crane telescopic oil cylinder stroke and a crane telescopic control signal are collected; according to the telescopic oil cylinder stroke and the crane telescopic control signal, an abnormal retraction condition of a crane telescopic oil cylinder is judged; according to the judgment result of the abnormal retraction condition of the crane telescopic oil cylinder, related data are processed; and if necessary, the data processing result is output and executed to avoid or lower damage caused by abnormal retraction of the telescopic oil cylinder, and therefore the operation safety of the crane is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical control, in particular to a crane control method, a system and a crane. Background technique [0002] Cranes include truck cranes, crawler cranes, port cranes, etc., used for hoisting, lifting, stacking and other work. [0003] When the crane is working, part of the weight of the load is borne by the telescopic cylinder of the jib. If the telescopic cylinder, the pipeline or components connected to the telescopic cylinder fail, the telescopic cylinder may retract under the action of the load gravity. Back is abnormal retraction. It can be seen that the telescopic cylinder has the risk of not retracting normally due to the failure of related components. [0004] The abnormal retraction of the telescopic cylinder is very harmful, which may cause damage to the crane and the load, and may also cause damage to the working environment of the crane, which should be avoided as much as possible.
