刮板输送机是煤矿井下工作面生产的重要运输工具, 随着工作面单产的提高,输送机逐步向大功率高强度发展。但生产实践证明, 刮板输送机事故为煤矿非伤亡事故之最。因此，认真研究分析其事故原因并针对煤矿企业的实际，从刮板输送机的产品设计方法、制造工艺过程、使用维护与设备管理角度出发，提出切实可行的技术改进措施，进而减少输送机事故，改善煤矿设备的使用性能，减少设备维护量，提高煤炭产量，提升企业核心竞争力有着十分重要的意义。 本文通过对甘肃省靖远煤业公司大水头煤矿近年来煤炭生产中使用过的输送机，主要是对靖远煤业公司机械制修厂新开发研制的SGZ730/320中双链刮板输送机现场使用情况的调查，收集刮板输送机发生故障的数据资料，利用故障树的方法，对刮板输送机运行影响最大、故障频率最高的故障点进行故障原因分析。针对刮板输送机设计参数诸多的不确定性，传统设计难以满足实际要求的现状，以刮板输送机电机功率最小和运输性能最佳为目标，建立优化数学模型，利用网格法对刮板输送机进行优化设计；采用虚拟样机技术，对刮板输送机的装配过程进行仿真，便于及时验证设计数据并修改，提高设计效率；在分析刮板输送机故障原因的基础上，从理论与实践角度分析了常见主要故障发生的原因；针对煤矿生产对刮板输送机运行可靠性、安全性要求不断提高的现状,提出了制造工艺技术改进措施；从加强使用维护的角度出发，提出了适用于刮板输送机日常现场使用维护和管理的流程图与检查维护方案，为提高现场的设备使用管理水平和降低故障率提供了依据。

Scraper conveyor is an important conveyance tool of coal production, along with exaltation that the work faces the list to produce, scraper conveyor gradually to high strength development of big power. But the fulfillment certificate that produce. Scraper conveyor’ trouble as the coal mine non- dead and injured trouble it is most. Therefore, the earnest research analytical its trouble reason aim at the coal mine business enterprise also actual, from pare off the product that the plank transports the machine design method, the manufacturing process planning, usage supports to equipments management to set out, putting forward slicing the solid viable technique improvement measure, then reducing to the fault of scraper conveyor, improvement the usage function of the coal mine equipments, reduce the equipments maintenance quantity, increase the coal yield, promote the business enterprise core competencies to have the very important meaning. This paper introduces the scraper conveyor of the Gansu province Jingyuan coal industry company Dashuitou coal who produces and uses in recent years, investigates mainly the usage circumstance of the scraper conveyor in the SGZ730/320 that the far coal industry company machine system of Jingyuan fixs the new development of factory to research to manufacture, the collections pares off the data that scraper conveyor occurrence breakdown, making use of fault tree analysis method , breaking down the tallest break down in frequency to carry on breaking down the reason analysis towards scraper conveyor to transport the luck to go to affect biggest. Aim at to scraper conveyor to transport the parameter many indeterminations of the machine design, the tradition design hard satisfy the present condition of actual request, with Scraper conveyor to transport the machine electrical engineering power minimum and conveyance the function is the best for target, build up excellent turn mathematics model, make use of the mesh method to scraper conveyor to transport the machine to carry on excellent turn the design. Adopt the virtual kind machine technique, verify to design the data to combine the modification towards really pare off the assemble process that the scraper conveyor to carry on imitate, easy toly in time, raise to design efficiency. In analyzing to pare off the foundation that the scraper conveyor breakdown reason, from the reason that the theories and the fulfillment angle analyzed the familiar main breakdown occurrence. Aim at the coal mine production to transport the present condition that the luck goes the credibility, the safety request to raise continuously towards scraper conveyor, put forward the manufacturing craft technique improvement measure. From strengthen the angle of use the maintenance to set out, put forward to be applicable to scraper conveyor to transport the machine uses the maintenance and management on the scene usually of flow chart and check support the project, for raise the equipments usage management level of the spot and lowered the breakdown rate to provide the basis.
