新型掘进机用第一运输机设计

掘进机第一运输机负责运输物料,其运输效率直接决定了掘进机的工作效率。针对目前掘进机工作过程中经常遇到的卡链、飘链等现象,提出了一种将螺旋输送机应用于掘进机的设计方案,探讨了螺旋输送机主要参数的设计方法,并对螺旋输送机的关键部件进行了有限元分析,校验了关键部件的强度和6阶固有频率,得到了可靠的分析结果,为螺旋输送机在掘进机上的应用提供了依据。

Design of First Conveyor for New Type Roadheader

The first conveyor of the roadheader is responsible for transporting the cargo,its transportation efficiency directly determines the working efficiency of the roadheader.For the phenomenon of the stuck chain,the floating chain and so on,which is often encountered during the work of the roadheader,put forward a designe scheme about the screw conveyor apple to the roadheader,the design method of the main design parameters of the screw conveyor was discussed,and the key components of the screw conveyor were analyzed by finite element,the strength and the sixth-order natural frequency of the key components were verified,and a reliable analysis result was obtained,which provides a basis for the application of the screw conveyor on the roadheader.
