摘要
针对传统斗轮堆取料机门座架强度和刚度差、耗材、存在安全隐患等问题,对门座架进行详细受力分析,在此基础上提出了新的门座架结构形式,以环形梁代替联结座圈,新的门座架受力好、节省材料、节省加工工序及加工量、安全可靠性高,可为斗轮堆取料机门座架的设计提供指导和参考。
Aiming at problems of portal frames of bucket-wheel stacker/reclaimer such as poor strength and stiffness, greater material consumptim and existence of safety hazards, detailed force analysis for portal frame is performed, and based on this, a new structure for portal frame is put forward, with jointing race replaced by the annular girder. The new portal frame is of good force-bearing condition and high safety reliability, and saves materials and machining work, so it can provide guidance and reference for design of portal frames of bucket-wheel stacker/reclaimer.
