Steel coil hoisting method and system

Abstract

The invention provides a steel coil hoisting method, and the method comprises the following steps of numbering and bagging, namely numbering the steel coils, selecting part of the steel coils to be bagged, and sending the serial numbers and the bagging information of the steel coils to a control system; displaying the serial number and the bagging information of the steel coils through the controlsystem; and sending a hoisting instruction to a travelling crane, wherein the travelling crane judges whether or not to hoist the steel coils to a specified position according to the bagging information of the steel coils in the control system. The steel coil hoisting method provided by the invention is reasonable in design and high in working efficiency, and can reduce the manual intervention times. The invention also provides a steel coil hoisting system.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a steel coil hoisting method and a hoisting system. Background technique [0002] Coil steel, also known as steel coil. The steel is hot-pressed and cold-pressed into rolls. In order to facilitate storage and transportation, it is convenient to carry out various processing (such as processing into steel plates, steel strips, etc.). The steel coil is characterized by its heavy weight and wide width, so it needs a crane for transportation. After the automatic control crane receives the lifting command, it automatically lifts the corresponding steel coil from the coiling position to the target position. During the hoisting process of the steel coil, the three sets of centering sensor devices on the clamp can judge the centering of the core of the clamp, in order to ensure Steel coils are hoisted safely. During hoisting, three sets of centering sensor signal feedback...

AI Technical Summary

Problems solved by technology

If one of the three sets of centering signals on the clamp fails to feed back normally before hoisting, it will cause the automatic crane to generate a safety alarm and be forced to interrupt the automatic operation, requiring manual intervention

In the cold-rolled intermediate product storage area, due to the influence of air humidity, the steel coils stored for an extended period of time need to be bagged to prevent the steel coils from rusting. When the automatic control crane lifts the bagged steel coils, it is limited by the centering signal of the clamps, resulting in coiling Failed to interrupt the automatic operation of the crane
