Abstract

Abstract:

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 1.588 6 mm, which meets the requirements of the loading bracket of gangue.

Key words: gangue warehouse, loading bracket at the entrance of warehouse, strength analysis, Ansys workbench, static analysis
