[Abstract]:Tonghua Iron and Steel Group Co., Ltd. (referred to as "Tong Steel Group"), founded in June 1958. Jilin Province is the largest iron and steel joint enterprise, the State Council revitalization of northeast old industrial base key support of iron and steel enterprises. By the end of 2009, with total assets of 31.283 billion yuan, 20553 employees, with an annual production capacity of 5.6 million tons of steel in 2010, China's top 500 enterprises ranked 262nd, China's top 500 manufacturing industry ranked 132nd. With the continuous expansion of the production scale of the company, the application of lifting equipment is more and more extensive, the large tonnage crane equipment is increasing more and more, and the company pays more and more attention to the safety of the equipment. At present, the company is using a total of 816 lifting machinery equipment, including: 368 bridge cranes, 27 gantry cranes, 421 electric hoist. Based on the actual situation of crane operation, this paper puts forward a scheme to improve the structure of wire rope winding system of crane drum, in order to solve the common problem of wire rope winding in high rise and large tonnage operation at present. Based on the basic theories of differential geometry, mechanical system dynamics, theoretical mechanics, material mechanics and elastic mechanics, the winding behavior of wire rope in LEBUS grooved drum is studied in this paper in terms of geometry, dynamics and statics. And based on the crane structure parameters to solve. The main research works are as follows: (1) the geometric model of wire rope winding in the drum is established, and the mechanism and geometric model of the ultimate deflection angle and the reversing process in the winding process are studied. (2) based on the analysis of the winding mechanism of the wire rope in the drum of crane, the mechanical behavior of the wire rope in the winding process of the drum is studied. (3) computer program is compiled to solve the above model. On the basis of parameter analysis, some suggestions for improving the structure of wire rope winding system are put forward, and the research in this paper is to explore the mechanical behavior of crane drum wire rope winding system. The purpose of this paper is to provide the theoretical basis for the further design of the system structure improvement.
