Control method for multi-layer stacking type large heavy object storing and taking lifting system

Abstract

The invention provides a control method for a multi-layer stacking type large heavy object storing and taking lifting system. According to the control method, a space coordinate system is constructed,a lifting device of a crane and the specific positions of cargoes can be determined in real time, and therefore storing and taking of the cargoes are accurately realized; and meanwhile, correspondingstorage areas are divided according to the type and size of the cargoes, serial numbers are distributed to the cargoes placed in a layered manner, and therefore the layer number of the cargoes and the positions of the cargoes on all layers are determined, and taking and placing are facilitated. By means of the control method, a plurality of cargoes can be effectively stored, and meanwhile, the problem that the multi-layer stacking type cargoes are inconvenient to store and take is solved. The control method combines an electromagnetic type lifting manner and a grabbing type lifting manner together, can be applied to the storing and taking processes of various cargoes, increases the applicable range of the crane, and also improves the safety in the lifting process.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a control method for a multi-layer stacking type large-scale heavy object access and lifting system. Background technique [0002] With the further deepening of the industrialization process, the popularization of industrialization and the acceleration of industrial chain upgrading, the needs of engineering users are gradually shifting to high-quality, energy-saving and fast, high safety factor, convenient maintenance, and perfect service. Cranes are widely used in factories, Warehouses, ports, buildings, construction sites, railways and other places. Cranes have a large working range, poor working environment, and many risk factors. Once an accident occurs, the machine is often destroyed and the scene is shocking. [0003] At the same time, in the engineering application process, multi-layer stacked heavy objects are more common. Because the volume is generally relatively large, a large ...

AI Technical Summary

Problems solved by technology

Due to the large volume, a large amount of manpower is required for handling, the storage efficiency is low, time-consuming and labor-intensive, and to deal with the problems of this type of cargo, it is necessary to design a special crane system

At the same time, for some places, there are various types of goods stored, and the shapes and sizes are different, such as cylindrical steel coils stored vertically, steel plates placed flat, and bundled steel bars or steel pipes placed flat. In order to make full use of the space, Some goods also need to be placed in layers. For these layered goods, sometimes it is necessary to take out the goods at the lower level when accessing them, such as multi-layer bundled steel bars stacked together. The thickness of the upper and lower steel bars is different. When the lower layer needs to be removed first, the whole control process becomes more difficult
