The Structure Design Of Experiment Platform For Mining Rope Shovel

In modern large-scale open mining,mining rope shovel replaces a large amount of human labor,makes the mining efficiency is greatly improved,plays an irreplaceable role.But at present,the artificial operation of mining rope shovel has low mining efficiency,high energy consumption and poor security.With the rapid development of science and technology,autonomous become one of the important direction of the development of mining rope shovel.Mining rope shovel realizes autonomous not only can effectively reduce artificial operation error,but also can improve efficiency,reduce energy consumption.Mining rope shovel equipment is large and expensive,transforming it and carrying out autonomous study are time-consuming and lack of security.To solve the above problems,I designed a mining rope shovel autonomous technology demonstration platform,the platform including hoist mechanism,crowed mechanism,swing mechanism,swing platform,such as structure,can be coupled mining environment 3d scanning and reconstructing,autonomous detection,autonomous mining,and autonomous protection system unit.The research content is as follows:(1)In accordance with the requirements of autonomous mining experiment,combining the basic situations of the experiment place,I put forward the general design requirements of the experiment Platform,and in accordance with the general design requirements I formulated the overall design scheme,including the mechanical structure design scheme,autonomous system design scheme and autonomous technical project,and I determined the main technical parameters and working way of the platform.(2)According to the mechanical structure design scheme and main technical parameters of the platform,I completed the structure design of the platform,including 3d modeling,motor selection,the standard component selection,non-standard structure design,etc.I coupled up the autonomous system unit and mechanical structure model of the platform,and adopted the reasonable way to install the autonomous system unit on the platform,finally determined the overall 3d structure model of the platform.(3)I analyzed and checked the 3d structure model of the platform,including transmission calculation,stability calculation,motor check,intensity check,kinematics analysis and motion simulation,etc.Analysis results showed that the platform has good overall stability,good mechanical strength and no movement interference.(4)According to the overall structure 3d model,I drafted assembly drawing and parts drawing,drew up the processing technology of each parts and whole assembly scheme.After the parts processed,I assembled the processed parts and standard parts,and then installed the autonomous system unit on the platform,finally completed the make of the experiment Platform.And then I carried out the experiment about the mechanical properties experimental verification of the experiment Platform,the experiment proved that the platform has good agencies performance,smooth operation,security and stability,and it can satisfy the requirement of autonomous mining experiment.The experiment Platform of the study has a whole small size,light quality,good safety and stability,can achieve the multiple assignment function of existing mining rope shovel.And it couples autonomous system unit,can be used to carry out autonomous mining experiment.It lays the foundation for the mining rope shovel autonomous technology research and the realization of the autonomous mining rope shovel.
