【摘要】：滚筒式采煤机作为综合采煤机械化的主要设备,具有高产量、高效率、适应性强等优点,被广泛应用于不同地质条件下的煤炭开采。螺旋滚筒作为采煤机上最主要的部件,其设计的好坏直接影响整机的工作性能。由于螺旋滚筒的设计自由度较大,设计参数众多,应用参数化方法进行设计是提高采煤机滚筒设计质量和设计效率的有效途径。本文通过对滚筒截齿排列原则与方式、截割顺序图及切屑图的形成过程与方法、截齿受力以及滚筒载荷模型的分析,深入研究了各因素之间的相互关系。在此基础上,利用MATLAB GUIDE功能设计可视化界面,编制相应的软件程序,开发出了采煤机螺旋滚筒设计的可视化系统。该系统通过在MATLAB GUIDE可视化界面中输入滚筒的设计要求和煤岩的参数,就可完成采煤机螺旋滚筒的可视化设计,并形象、直观地显示各种设计参数下的截齿排列图、相应的截割顺序图、切屑图、滚筒的载荷曲线,且能对其设计结果进行优化。本文介绍了所建立的采煤机螺旋滚筒的设计理论和方法,研究了各种工况下对采煤机滚筒截割性能的影响,所作的研究及其成果对采煤机螺旋滚筒的设计有一定的指导作用,对提高采煤机滚筒的设计质量和设计水平、改善滚筒采煤机的截割性能具有重要的意义。
[Abstract]:As the main equipment of comprehensive mining mechanization, drum shearer has the advantages of high yield, high efficiency and strong adaptability. It is widely used in coal mining under different geological conditions. As the main component of shearer, the design of spiral drum directly affects the performance of the whole machine. Because of the large degree of freedom and numerous design parameters, the application of parameterized design method is an effective way to improve the design quality and design efficiency of shearer drum. Based on the analysis of the principle and mode of gear cutting arrangement, the forming process and method of cutting sequence diagram and chip chart, the force of cutter cutting and the load model of roller, the relationship between various factors is deeply studied in this paper. On this basis, the visual interface is designed by using MATLAB GUIDE function, the corresponding software program is compiled, and the visual system for the design of shearer spiral drum is developed. By inputting the design requirements of the drum and the parameters of the coal and rock in the MATLAB GUIDE visual interface, the system can accomplish the visual design of the spiral drum of the shearer, and visualize the arrangement diagram of the cutter under various design parameters. The corresponding cutting sequence diagram, chip diagram and the load curve of the drum can be optimized. This paper introduces the design theory and method of the screw drum of shearer, and studies the influence of various working conditions on the cutting performance of shearer drum. The research and its results have a certain guiding effect on the design of shearer spiral drum. It is of great significance to improve the design quality and design level of the shearer drum and improve the cutting performance of the shearer.
