Lifting appliance anti-collision protection method, controller, system and quay crane

Abstract

The invention relates to the field of engineering machinery, in particular to a lifting appliance anti-collision protection method, a controller, a system and a quay crane. The anti-collision protection method for the lifting appliance comprises the following steps: acquiring running state information of the lifting appliance; obtaining a predicted running track of the lifting appliance; acquiring position information of an obstacle; generating prompt information according to the predicted running track of the lifting appliance and the position information of the obstacle; when the prompt information prompts that the lifting appliance collides with the obstacle, a control instruction is generated according to the predicted moving track and the position information of the obstacle, and the control instruction is used for prompting or controlling the lifting appliance to avoid the obstacle. By predicting the running movement track of the lifting appliance and adjusting the movement parameters of the lifting appliance in time, the anti-collision protection effect on the lifting appliance is achieved, when the risk that the lifting appliance collides with an obstacle does not exist, the problem that the safety distance between the lifting appliance and the obstacle is kept too large is also solved, and therefore the working efficiency of the lifting appliance is guaranteed.

Description

technical field [0001] The present application relates to the field of engineering machinery, in particular to a method, controller, system and quay crane for anti-collision protection of a spreader. Background technique [0002] Shore-side container cranes (referred to as quayside cranes or suspension bridges) are professional equipment specially used for loading and unloading container ships at container terminals, and are generally installed on the shore of port terminals. In the quay crane operation site, due to the tight time and heavy tasks, it is easy to make mistakes in the operation during the movement and work of the spreader, resulting in the collision between the spreader and the container or the hull and other obstacles or when the container is carried by the spreader. Collisions with surrounding objects. Not only will it cause property damage, but also affect personal safety, so the anti-collision protection of the spreader is particularly important. [0003]...
