摘要
为了满足开滦矿区林西矿11#煤层综采工作面的开采需要,创新设计了折叠式抬底装置,以实现支架在移架时的自动抬底要求。该抬底机构结构简单,可靠性高,不占用行人空间,解决了薄煤层支架移架难的问题,应用前景广阔。
In order to meet the needs of 11 seam fully-mechanized face of Linxi coal mine of Kailuan,the folding bottom lifting device is designed to realize the automatic lifting bracket in the moving frame at the end of the time requirements. The structure of the bottom lifting device is reasonable and reliable, and it does not affect the pedestrian space. It solves the problem of thin coal seam support moving frame difficult, and has broad application prospects.
