Research On Support Vehicles Of Coal Mine Horizontal Belt Extension Machine

In the course of normal mining and safety of the raw coal production, coal transportation system of coal mine has been the important link of the whole mining system. The main problem of coal mine transportation system exists not continuous work, meanwhile, some problems still exist, such as the loader of the high safety factor, manufacturing materials and use of the machine is not enough saving and environmental protection, In order to make the structure of the transportation system more rational and more green, more in line with the concept of energy saving in the use of design and manufacturing process, the subject of coal mine horizontal extension of the loader design to make the coal mine. This article on the subject based on previous work for the coal mine horizontal extension of the loader support vehicles conducted by the ministry of the green optimized design.First, the overall structure and working principle of the coal mine horizontal extension loader, and expounded the meaning and significance of the green coal mine machinery optimization design, combined with the research status at home and abroad, pointed out that the green optimize the design of coal mine loader the need to study. Extension of the various parts and components of the loader support vehicle department on the material and structural aspects of the coal mine horizontal green optimize the design, laid the foundation for the whole green optimization.Secondly, the use of Pro/Engineer3D software to establish the three-dimensional model of a coal mine horizontal extension of the loader support vehicle body, three-dimensional model in ANSYS static analysis, support vehicle body in the role of the static load the structure of the node deformation, stress and strain diagram. The results verify the original supporting vehicle body structure stiffness and strength to meet the work requirements, structure and material optimization. In order to support vehicle body design optimization, respectively, from both structural parameters and material properties to change the three-dimensional model to optimize, and again the finite element analysis, in order to achieve the objectives of the Green optimization.Then, again using ANSYS software to analyze and check the dynamic characteristics of the optimized support the vehicle body. Through the first six order natural frequency and modes of supporting vehicle body and the response curve of the values and in the analysis of the different frequencies obtained by the harmonic response. The analysis results demonstrate the support vehicle body in the green optimized design its dynamic performance and stability.Finally, the coal mine horizontal extension of the loader support the green vehicle body optimization design evaluation to explore a coal mine horizontal extension of the loader support vehicle green optimal design method, an extension of the other parts of the loader after the coal mine underground horizontal and similar machinery, green-optimized design provides a theoretical reference.
