Abstract

The invention discloses a container-lorry alignment system of container crane and the method. Image pickup equipment set above the loading and unloading position of crane is used to shoot lorry image in real time and transfers the image to the image processing computer. The image processing computer combines pre-storing simulating lifting-tool profile into data image and transfers combined image to display controller by net in real time so as to control the display to display combined image set at the front of loading and unloading position of crane in visual field of lorry driver to help driver accomplish predetermining lorry. At least one suit of laser scanning equipment set on the front beam and back beam of crane is used to collect profile information of lorry or container on the lorry and transfer the information to computer system. The computer system carries out data filter to profile information and characteristic fitting. The information is contrasted with theoretical setting value and position error of lorry or container to the crane is analyzed and is transferred to the error display at the front of loading and unloading position of crane for displaying so as to help driver accomplish accurate position for lorry.

Description

technical field [0001] The invention relates to a container crane, in particular to a method and a system for aligning the truck with respect to the position of the spreader when the truck is loaded and unloaded under the container crane. Background technique [0002] The development of the container shipping industry has put forward higher and newer requirements for the technology of container cranes; improving the productivity of operations and reducing the labor intensity of operators is an eternal subject of the development of container crane technology. [0003] The loading and unloading of containers between container cranes and ground container trucks is a bottleneck that restricts the efficiency of container terminal loading and unloading. How to improve the alignment speed between crane spreaders and container trucks to improve loading and unloading efficiency is a key issue for port crane manufacturers and related technologies. What experts have been working on. ...
