【摘要】：我国是世界上煤炭资源最丰富的国家之一,不仅储量大分布广,而且种类齐全,煤质优良,为我国工业现代化提供了极为有利的条件。随着机械制造业的迅速发展,以及人们对加工精度和生产效率的高要求,采煤机械化生产对生产加工所需设备和一些辅助运输设备的设计也提出了更高的要求。矿用刮板输送机作为综采设备的输送工具扮演着重要的作用,它是用无端循环运动的刮板链条作为牵引构件,电机驱动机头或机尾链轮提供驱动力,刮板链条在多节铠装的敞开式料槽内连续输送煤炭的输送机械。因此,刮板链条传动系统是刮板输送机最为关键的部分,其运动特性直接影响着刮板输送机整机的输送能力和工作效率。本文以链传动系统运动学及动力学行为研究为基础,进行了刮板输送机工况分析与载荷计算;应用SolidWorks软件建立矿用刮板链条的实体模型;模型导入ADAMS动力学软件,并且给材料赋予属性,确定约束及边界条件,分析矿用刮板输送机链传动系统的固有特性,研究链传动横向振动、纵向振动而引起矿用刮板输送机链条的突跳,以及非正常工况下产生的卡链及断链现象;进行整机的有限元模型的分析,可为用于生产实践中的机械传动装置的动态分析与设计提供参考,从而提高埋刮板输送机整机的性能和效率。本文对刮板输送机链传动系统所做的静、动态特性的研究和分析,可以为其它链式送料机的设计和研发提供了借鉴。
[Abstract]:China is one of the countries with the most abundant coal resources in the world. It not only has a wide distribution of reserves, but also has a wide range of types and excellent coal quality, which provides an extremely favorable condition for the industrial modernization of our country. With the rapid development of mechanical manufacturing industry and the high requirement of machining precision and production efficiency, the design of equipment and some auxiliary transportation equipment for coal mining mechanization is also required. The scraper conveyer plays an important role as the conveyer of fully mechanized mining equipment. It uses the scraper chain with endless circulation as the traction component, and the motor drives the head or tail sprocket to provide the driving force. Scraper chain conveys coal continuously in a multi-section sheathed open tank. Therefore, the scraper chain transmission system is the most important part of the scraper conveyor, and its motion characteristics directly affect the conveying capacity and working efficiency of the scraper conveyor. Based on the research of kinematics and dynamic behavior of chain drive system, this paper analyzes the working conditions and calculates the load of scraper conveyer, establishes the solid model of mine scraper chain by using SolidWorks software, and introduces the model into ADAMS dynamic software. It also assigns attributes to the material, determines the constraint and boundary conditions, analyzes the inherent characteristics of the chain transmission system of mine scraper conveyor, studies the transverse and longitudinal vibration of the chain drive and causes the sudden jump of the chain of mine scraper conveyor. The finite element model analysis of the whole machine can provide a reference for the dynamic analysis and design of mechanical transmission device used in production practice. So as to improve the performance and efficiency of the burying scraper conveyor. The research and analysis of the static and dynamic characteristics of the chain drive system of scraper conveyer can be used for reference for the design and development of other chain feeder.
