立井用铰接式防爆无轨运输车关键技术研究

为解决立井煤矿人员、物料及设备无轨化运输难题，针对立井罐笼空间受限和井下多样化运输需求，以及井下通风差、巷道坡度大等特殊工况，提出采用平台化研发模式，首先开发一种铰接式清洁动力传动平台，并基于平台拓展研发系列无轨胶轮车的技术方案。阐述了整车总体设计、主参数确定、平台开发、驾驶单元多模式设计、工作装置拓展设计及清洁排放和安全保障等关键技术。应用以上关键技术的无轨胶轮车在晋能集团王村煤矿和山西三元煤业完成了使用验证，试验表明整车技术性能完全满足生产现场需求，且产品功能覆盖全，通用性强。上述关键技术、设计思路及方法的研究，可解决无轨车辆直接进出立井罐笼、运输需求多样及井下清洁与安全保障等难题，加快无轨化运输在立井煤矿的推广应用。

Research on the key technology of articulated transport vehicle for shaft cage based on clean power and transmission platform

In order to solve the problem of trackless transportation of personnel, materials and equipment in vertical shaft coal mines, in view of the restricted space of vertical shaft cages and the diversified transportation needs of underground, as well as the special working conditions such as poor ventilation and high slope underground, a platform-based R&D model is proposed to first develop a clean power and transmission platform based on which the development of a series of trackless rubber wheeled vehicle. The key technologies such as the overall design of the vehicle , determination of the main parameters, development of the platform, multi-mode design of the driving unit, expansion design of the work unit and cleaner emissions, safety assurance of the vehicle are described.The articulated trackless rubber wheeled vehicles for vertical shafts applying the above key technologies and design solutions have been verified in Wangcun coal mine of Jinneng Group and Shanxi Sanyuan coal industry.The test results show that: the technical performance of vehicle fully meets the needs of the production site, and the products covers the full range of functions and highly versatile. The research on the above key technology, design ideas and methods can solve the problems of the trackless vehicles enter and exit the vertical shaft cage directly, diverse transportation needs and tailpipe pollution, poor safety protection, which can accelerate the application of trackless transportation in vertical shaft coal mines.
