摘要
通过对井下挡矸支架顶梁连架防倒筒的损坏分析,对现有结构进行优化设计、现场改造,以达到增强现有结构强度的目的。改造后的防倒筒结构经过井下实际应用的检验,达到预期效果。
Analyzed the damage of the top beam connecting frame and anti overturning tube of the underground gangue support,optimized the design and on-site renovation of the existing structure,in order to enhance the strength of the existing structure.The modified anti overturning tube structure has been tested in practical underground applications and achieved the expected effect.
