Research On Tractor Of Coal Mine Horizontal Belt Extension Machine

After studying many underground roadway with loading machinery found that almost all the mechanical equipment can’t fundamentally solve the problem of the continuity of downhole load. By analyzing the problems, find solutions, we put forward an applied in coal mine can solve the problem of loading of the continuity of the reprint machine, we call it the coal mine (belt), horizontal extension stage loader. In view of the coal mine horizontal extension stage loader structure complexity, so this article only for extending reproduced machine power components-tractor for research.First of all, to the coal mine belt horizontal extension reproduced machine’s overall composition, working principle, main data parameters and its scope of application, etc. A brief elaboration, and supplemented by3d figure of the structure characteristics and working principle of each component and the key points of design, material selection, etc are explained briefly.Secondly, to extend reproduced machine tractor structure design in detail. The tractor in accordance with the function is divided into several parts:meet funnel, control box, belt brackets, traction, belt drive, walking, driving, braking system, frame and sanding mechanism, etc.; Detailed structural design for each component; Through PROE software to establish three-dimensional model of tractor parts, through the model of intuitive display tractor structure; According to have good design or selection of the size of each component and tractor working conditions in be used actually need reasonable space arrangement, and make the structure more compact tractor.Then, create extension reproduced machine tractor chassis3d model, and simplified to facilitate analysis of the model is necessary;3d model will be saved as IGES or x-t format file, and import the ANSYS software; According to the statics analysis of the tractor frame to develop cars and the size of the frame; According to different dimensions respectively build finite element model of the tractor frame and according to the analysis of the initial solution is the same with the tractor frame step, statics analysis for multi-group analysis results; By comparing the values in different size under the tractor frame deformation, maximum stress and the weight of three groups of data analysis results, to get the best scheme of tractor frame size.Finally, the extension stage loader for alternative materials discussed in this paper. We use light engineering materials to replace the original steel, according to the statics analysis has been made to the same size, maximum deformation, stress and weight three groups analysis data; Will be two kinds of materials, comparing the results of the analysis by comparison to select the best material, reasonably and scientifically on the basis of complete frame of lightweight design.
