煤炭开采中，1.3～1.8m的薄煤属于薄煤层，其作业空间小、工作条件恶劣、回采效率低，目前国内缺乏长运距、通用程度高的薄煤层输送设备。为了满足薄煤层工作面高产高效、自动化开采的需求，本文对薄煤层自动化工作面总体配套技术进行了研究，提供了配套设备选型方案，并设计开发了配套设备中的SGZ764/630型薄煤层刮板输送机。主要研究内容和工作如下： （1）根据使用矿区和工作面地质情况，进行了工作面设备选型和配套研究，重点研究输送设备选型，确定了输送机主要技术参数，降低了设备整体配套高度。为设备使用矿区及相似地质条件下的使用提供了顺槽掘岩量少、适应性好的设备选型方案。 （2）完成了薄煤层输送机整体结构方案的设计，确定了中部槽、链轮组件、机头架、自动伸缩机尾和电缆槽等零部件结构和尺寸，优化了设备结构和性能。研究了中部槽的水平和垂直弯曲角度，通过分析中部槽推进中的漂溜与啃底现象，进而合理设计推移点的高度；链轮设计中进行了齿形和轴承寿命的核算；自动伸缩机尾分析计算了其控制系统压力的设定范围；针对采煤机电缆无人看守，进行了电缆槽结构的设计改进。 （3）建立刮板和刮板E形螺栓实体模型、有限元模型，分析了刮板E形螺栓和立环在920kN和1270kN载荷条件下的应力与变形分布规律，分析结果认为其强度、刚度满足设计要求，并对其进行了优化设计。 （4）进行了薄煤层输送机成套设备地面联合调试，初步完成了对成套设备的配套尺寸和性能检测，输送机电缆槽结构满足采煤机无人跟机运行的要求；实现了刮板输送机、转载机的顺序启动、停止、顺序闭锁功能和变频软启动功能。

In coal mining，1.3 ~ 1.8 m thin coal seam mining has the character of little working space, bad working condition, and low recovery efficiency. Current domestic is lack of long distance, high degree of general-purpose thin coal seam conveying equipment. In order to meet requirements of relatively thin coal seam face’s high yieid and high efficiency and automation production ,this paper provided the equipment selection, designed and developed thin coal seam AFC SGZ764/630, suitable for thin seam working face. The main research and work is as follows: (1) According to the using area and working face condition, studying mining equipment selection and matching, focused on the research of conveying equipments model selection, confirming main technical parameters and lower mating height. Provides a equipment type-selecting scheme of gateway little rock digging and good adaptation for equipment’s useing mine and the use of similar mining geological conditions. (2) Completed structure design of thin seam AFC. Determined the structure and size of the line pan, the sprocket assembly, the head frame, the automatic telescopic tail end and the cable trough, optimized the device structure and performance. Studied the horizontal and vertical bending angle of the line pan. Goes on analysis of the floating and gnawing the floor in AFC, calculation to a line pan passing point height, a sprocket tooth shape and bearing life, automatic telescopic tailend control system pressure setting range and other technical key points. In view of the coal winning machine cable be unmanned, this paper gives the design of the cable trough structure improvement. (3) Through the establishment of scraper and scraper E bolts three-dimensional solid model, optimized design; made the deformation analysis respectively, taken the 920 kN and 920 kN load distribution. The analysis results meet the design requirements. (4) Taken ground joint debugging, completed preliminary the detection on gap size and performance of complete sets of equipment, cable trough structure satisfies the requirement of shearer self-service running. Implements the order of the scraper conveyor, reversed loader start, stop, order closure function and variable frequency soft start function.
