随着综采工作面生产能力的快速提高,国内外刮板输送机都在向大运量、大运距、大功率、长寿命、高强度的方向发展。端卸式机头架已经难以满足刮板机发展的要求。经过不断地创新、改进,国内外重型刮板输送机的机头架均采用交叉侧卸机构,侧卸式机头架与端卸式机头架相比较,具有卸载能力及回煤效果好、使用寿命长、工作效率高等多方面优势。主要对侧卸式机头架的几点设计参数进行分析。
With the rapid increase of production capacity of fully mechanized coal mining face, scraper conveyor at home and abroad are developing toward large capacity, large distance, high power, long life and high strength. End-dump headframe has been difficult to meet the requirements of the development of scraper. After continuous innovation and improvement, both domestic and foreign heavy-duty scraper conveyor head rack are cross-side dumping mechanism, the side-dump head rack and end-dump headframe compared with the unloading capacity and good effect of back to the coal, Long service life, high efficiency and many other advantages. Mainly on the side of the aircraft headframe design parameters are analyzed.
