摘　　要：重型矿车作为露天矿山重要的物料运输装备,其工作环境恶劣,长时间的运输作业会加速轮胎老化、磨损。目前,重型矿车轮胎的更换以及检查工作主要是采用传统的液压顶升装置来实现,需依靠大量的人力和辅助设备,导致维修效率低、安全性能差。为解决以上问题,研发了一款融合人工举升和液压举升优势的多功能举升装置。该设备可通过千斤顶、剪叉伸缩装置和机械支撑块3部分的协同配合,实现对重型矿车前后方位不同姿态的同步顶升,满足大多数型号重型矿车顶升作业的要求。基于有限元分析方法对设备关键零部件进行强度分析和理论验证,结果表明:该设备满足设计使用要求,最大举升载荷为2548 kN,最大举升行程为0.85 m,具有高承载性能和良好的适应性,能够实现对多种型号重型矿车的快速辅助维修,提高了维修工人更换和检查巨型轮胎的工作效率。As an important material transportation equipment in open-pit mines,heavy mining trucks work in harsh environments,and its prolonged transportation operations will accelerate the tire aging and wear.At present,the replacement and inspection of tires for heavy mining trucks mainly rely on the traditional hydraulic jacking device,which require a large number of manpower and auxiliary equipment,resulting in low maintenance efficiency and poor safety performance.To solve the above problems,a multi-functional jacking device integrating the advantages of artificial lifting and hydraulic lifting was developed in this paper,which could realize the synchronous lifting of heavy mining trucks in different postures in front and rear directions through the coordination of jacks,scissor expansion devices and mechanical support blocks to meet the requirements of lifting operations of heavy mining trucks in most types.Then,based on the finite element analysis method,the strength analysis and the theoretical verification of the key parts of the equipment were carried out.The results showed that the equipment met the design requirements,with a maximum lifting load of 2548 kN and a maximum lifting stroke of 0.85 m.It had high load-bearing performance and good adaptability,and could realize the rapid auxiliary maintenance for many types of heavy mining trucks,which greatly improved the efficiency of the maintenance workers for replacing and inspecting giant tires.
