Research On Real-time Life Assessment Methods For Main Components Of Bridge Crane Hoisting Mechanism

Bridge crane in various trades and industries as today’s major auxiliary equipment, it is used in the machinery industry, steel industry, shipbuilding industry and the aviation industry. This can be seen bridge crane occupies an irreplaceable position in the lifting device. Because of its heavy task, labor intensive, work frequently, the failure will often occur. Lifting mechanism is the main working body of bridge crane, it is an integral part of each bridge crane, it bears the important task of lifting cargo, it is due to the importance of their function. If the lifting mechanism fails, it will have extremely serious accidents and casualties.The issue of bridge crane hoisting mechanism for real-time study of the main components of life assessment. In failure cases of understanding the main components of the lifting mechanism, by analyzing the importance of lifting mechanism from each major component, thus prefers the hoisting rope and brake as research subjects, that rope:In bridge crane on the basis of the real-time running data, combination of wire rope winding on different, proposed to the bridge crane hoisting rope life assessment method in real time. By segmenting the bridge crane wire rope, when hoisting in real time, to establish the subsection hoisting wire rope up and down and under the big and small car the mechanical model of the payload, analysis of the segments on the point of the whole real-time stress, the wire rope safety monitoring and management and life assessment. This method can be different points in the life of real-time monitoring, thus completing point to the segment then to overall of the rope supervision, time to find the damaged location, and combined with VB software development, make the method more practical. Brakes also take real-time status detection, quick evaluate real life of the brake and fast and timely replacement of damaged parts. The problem is usually solved bridge crane hoisting mechanism component life assessment is based on the study of the state of the data of the state. While also addressing the business due to the timing of periodic inspection bridge crane and can not be rapid alert, the increase in the accident rate.
