大型桥式双料耙刮板取料机关键问题设计研究

Research on Key Issues in Design of Large Bridge Scraper Reclaimer

分析了超大型料耙系统的料耙阻力计算,采用新型主铰点结构和连接板的设计解决了超大型料耙的疲劳设计难点,同时也研究了料耙的换向防冲击和解体发运。研究了不同料堆位置时行走机构工作速度的计算原理,确定了正常工作速度的计算公式,提供了应用实例,分析结果表明料堆位置对行走速度的影响可以忽略不计。研究的方法和思路能够合理地指导设计,为大型桥式刮板取料机的精细化设计提供了重要的理论参考,也为其他刮板取料机的设计提供重要的参考借鉴。

Analyze the force calculation of the ultra-large harrow, apply the new joint structure and connection design in order to solve the design difficulties for the fatigue of the harrow, and also analyze the striking resistant during the reversing, also analyze the disintegration and transportation for the harrow. Provide the research on the travel speed calculation principle of the long travel during the different stockpile position, and determine the calculation formula, provide the project application, the result shows the stockpile position is negligible for the long travel speed. The whole study will provide a reference for the similar design and optimization of the bridge scraper reclaimer and other reclaimer.
