摘 要 刮板输送机是一种具有挠性牵引机构的连续运输机械，主要供采煤工作面使用。在煤矿井下综采工作面中主要承担的任务是将采煤机采下的原煤连续不断地运往转载机，确保综采工作面的原煤连续运出。它要求机身高度小，便于装载；运输能力满足使用地点的生产需要；结构坚固，能抵抗压、砸和碰撞；变更运输距离时，加长和缩短方便；能够不拆卸用机械移置。 根据所给设计参数和工作环境的要求，通过对刮板输送机的发展情况、发展趋势、结构组成、工作原理、种类及作用进行分析，对SGD730/180型刮板输送机输送能力的计算、水平弯曲段几何参数的计算、运行阻力的计算、链条张力和牵引力的计算、电机功率的计算、溜槽推移阻力的计算、链条预张力和紧链力的计算及链条强度的计算等，完成刮板输送机结构改进，绘制了SGD730/180型刮板输送机总图、机头传动装置等结构设计。完成了The use of Scraper conveyor的翻译工作。 关键词 刮板输送机 结构设计 理论计算 Abstract Scraper conveyor is a kind of flexible traction for the transport machinery, Primarily for the use of coal face. Fully mechanized coal mine in the coal face of the main tasks is to undertake the mining of coal Shearer continuously reproduced to the machine, Ensure that the fully mechanized coal face of the coal for export. It requires a high degree of the fuselage of small, easy loading; The use of transport capacity to meet the needs of production sites; Solid structure, can resist pressure, smashing and collision; Change the distance, the lengthening and shortening the convenience; can not demolished by mechanical removal. According to the design parameters and environmental requirements, the scraper conveyor through the development of the situation, the trend of development, structure, working principle, types and roles of the SGD730/180-scraper conveyor transport capability of calculation , The level of the bending of the geometric parameters, the operation of the resistance, the chain tension and the traction, electrical power, the resistance to passage of the chute, the chain of pre-tension and tight links of the chain of calculation and the calculation of strength, to complete scratch Board conveyor structure improvement, drawn-scraper conveyor SGD730/180 the map, the nose gear, such as structural design. Completed The use of Scraper conveyor of the translation work.
