毕业设计（论文）-刮板输送机机身自动调直装置.doc

摘要 本论文介绍了综采面刮板输送机机身自动调直装置的设计过程，主要介绍了刮板输送机在国内外的发展状况发展趋势以及早期的调直装置和当下比较先进的调直方法，与目前进行的刮板机机身自动调方法的研究紧密相连。 本文在设计刮板输送机机身自动调直装置的过程中，运用理论分析，电路设计和计算机仿真等研究手段，完成了调直装置硬件与软件的设计。该系统分为测距模块、测温模块、支架控制模块、CAN总线通讯模块、调直控制器模块、电磁阀驱动模块以及人机交互模块块，并分别对其进行方案分析，构建了调直装置的构架和设计方案。在硬件电路中详细阐述了运用单片机技术实现的调至装置中的测距原理、测温原理以及通讯方案等，分析了以ATmega16 单片机为主控单元的系统硬件和软件设计,并对该系统进行了误差分析。 本文还对整体的外壳进行了详细的设计，根据材料力学的相关知识对外壳板进行了强度和刚度的分析，从而确定了外壳箱体的厚度。通过对外壳盖的受力分析确定了连接方式和固定螺钉的参数。实现了从理论到实际化的过渡。 关键词：刮板输送机； 超声波测距； ATmega16； CAN总线；  Abstract This paper introduces the design process of the fully automatic straightening device of mechanized coal face scraper conveyor, mainly introduced the scraper conveyor development at home and abroad and the development trend and the early straightening device and the current advanced straightening method, closely connected with the research of the automatic straightening method of scraper machine. Automatic straightening device comprises a bracket shifter, network converter, main connector, scraper machine straightening controller and scraper transporter fuselage. Network connection converter by trunk connector and the scraper body straightening controller, and communicate through the trunk connector, in each section of scraper conveyor middle groove are connected with the end of the bracket shifter, each bracket shifter and another end is connected with the network converter. Scraper machine straightening controller determines the control scheme and sends control signal by comparing the test data with the theory of poem analysis; control system through the network converter transmits control signals to the target frame controller, change the path of electromagnetic valve, scraper machine straightness adjusting. The device can realize mechanized mining face basically keep straight propulsion, ensure the scraper body straight to ensure coal mining machine running smoothly, and to realize the effective management of fully mechanized coal face roof, ventilation. This paper, in the design proces
