摘要
为满足具备无轨运输条件的煤矿钻探施工作业的快转快运的需要,采用无轨胶轮车集成钻机从地面直接行驶到钻场而无需二次转运,有效减少辅助运输人员并提升运输效率。通过对比整体式和铰接式底盘结构优缺点,根据实际井下巷道条件确定为窄体胶轮式底盘结构,并给出了整车设计关键性能参数。依据总体技术方案需求,对无轨胶轮车多项关键技术进行设计与分析,并对车架的行驶过程和施钻过程两种工况下的静承载能力和动态特性仿真分析,仿真结果表明:应力、位移均满足行走和施钻过程中车架承载能力的设计要求,且具有较好的稳定性。胶轮式底盘装调完成后,开展爬坡试验和全面性能测试,试验表明:整车满足15°大角度爬坡工况,各项数据符合标准规定要求,性能满足煤矿井下钻机的运输需求,能够适应煤矿井下复杂工况条件。
In order to meet the needs of fast and efficient transportation for coal mine drilling construction operations with trackless transportation conditions,a trackless rubber tyre vehicle integrated drilling rig was used to travel directly from the ground to the drilling site without the need for secondary transportation.By comparing the advantages and disadvantages of integral and articulated chassis structures,the narrow body rubber tyre chassis structure was determined based on actual underground tunnel conditions,and key performance parameters for the vehicle design were provided.By comparing the advantages and disadvantages of integral and articulated chassis structures,the narrow body rubber tyre chassis structure was determined based on actual underground tunnel conditions,and key performance parameters for the vehicle design were provided.Based on the overall technical requirements,multiple key technologies of the trackless rubber tyre vehicle were designed and analyzed,and the static load capacity and dynamic characteristics of the frame under two working conditions,namely the driving process and the drilling process,were simulated and analyzed.The simulation results show that the stress and displacement meet the design requirements of the frame load capacity during the walking and drilling processes,and it has good stability.After the installation and adjustment of the rubber wheel chassis,a climbing test and comprehensive performance test were carried out.The test shows that the whole vehicle meets the 15°large angle climbing condition,all data meet the standard requirements,and the performance meets the transportation needs of the coal mine drilling rig.It can adapt to the complex working conditions underground in coal mines.
