Reduction Design And Analysis Of The Lifting And Loading Part Of Silt Coal Loader Machine

In the normal operation of the mine and production safety, cleaning the silt coal in water storage is very important. The current silt coal cleaning up machinery of water storehouse in coal mine mostly also have some problems. For example the design safety coefficient is high. Manufacturing process is not economical and environmental protection and so on. In order to reduce the size of the silt coal cleaning up machinery, increase its safety and generalization, make sure the design and manufacturing process accord with the concept of energy saving and contaminant reduction. The topic of "reduction design and research of the silt coal loader machine" was raised. On the basis of the previous work, carried on the reduction design and analysis of the lifting and loading of silt coal loader machine.Firstly, the overall structure and the work principle of the silt coal loader machine were introduced. And the meaning and goal of quantity-reducing for mine machinery design was expounded. Combining domestic and foreign research status, the necessities of the reduction research for the silt coal loader machine was pointed out. Through the materials and structure, the reduction screening was carried on for the parts of lifting and loading of silt coal loader machine. The foundations of the reduction design of the whole machine were laid.Secondly, using Pro/Engineer software, the 3D models of lifting and loading trough of silt coal loader machine was build. In ANSYS software, the static analysis for lifting and loading trough model was provided. And the static load node structure deformation,stress and strain cloud figure were got. The results proved that the structure of the lifting and loading trough meet the stiffness and strength requirements, and has certain space to optimize. In order to make the design of the lifting and loading trough optimization, respectively from the aspects of changing the model structure parameters and material properties to optimize. In order to achieve the goal of reduction design used ANSYS software to make the finite element analysis again.And then, the dynamic characteristic of the optimized model of the lifting and loading trough were analyzed and checked. Through the modal analysis, the first six order natural frequency and vibration mode of the lifting and loading trough were got. Through the harmonic response analysis, the changing curves at the different frequency response values were got. The results proved the lifting and loading trough dynamic performance is stable after the reduction design.Finally, green design evaluation of the reduction design of the lifting and loading part was carried on. The reduction design general method of silt coal loader machine was discussed. And a theoretical reference for similar mechanical design was provided.
