矸石仓仓口装车支架部可靠性分析与研究

Reliability analysis and research on loading bracket at the entrance of gangue warehouse

为研究矸石仓仓口装车支架的结构强度,首先,借助solidworks软件构建某矸石仓装车支架主要零部件的三维结构模型;然后,根据实际装车情况,在矸石装车过程中,分析矸石仓仓口的支架强度和变形情况,以验证仓口装车支架部的可靠性;最后,把创建的三维模型导入Ansys workbench中进行静力学分析,并在规定正确约束的情况下,得到主要零部件的应力、应变分析图。结果表明:当支撑滑轮为6时,支撑滑轮最大承受载荷为83.921MPa,定量仓承受载荷为21.104 MPa,最大变形量为1.5886 mm,满足矸石装车支架承载矸石的要求。

In order to study the structural strength of the loading bracket at the entrance of a gangue warehouse,the three-dimensional structural model of the main parts of the loading bracket of a gangue warehouse was constructed by using solidworks software.Then,according to the actual loading situation,in the process of gangue loading,the strength and deformation of the bracket at the entrance of the gangue warehouse were analyzed to verify the reliability of the bracket.Finally,the created 3D model was imported into Ansys workbench for static analysis.The stress and strain analysis diagrams of the main parts were obtained under the correct constraints.The results show that when there are six support pulleys,the maximum load of the support pulley is 83.921 MPa;the load of the quantitative warehouse is 21.104 MPa,and the maximum deformation is 1.5886 mm,which meets the requirements of the loading bracket of gangue.
