The invention provides a connecting structure for a dump truck box and a chassis of an underground mine car, and relates to the technical field of mine underground operation. The carriage is positioned above the chassis; the number of the connecting assemblies is two, and the two connecting assemblies are installed on the chassis and the carriage. The number of the limiting assemblies is two, and the two limiting assemblies are installed in the two connecting assemblies. The number of the lubricating assemblies is two, and the two lubricating assemblies are installed on the two limiting assemblies. The stabilizing assembly is mounted on the chassis and the carriage; the number of the positioning assemblies is two, and the two positioning assemblies are installed on the front side and the rear side of the stabilizing assembly. When a worker presses the lubricating oil extrusion rod inwards, lubricating oil in the limiting pin shaft flows out through one or more lubricating holes, and precise lubrication is achieved; the problems that a worker needs to lubricate through an external lubricating instrument during lubricating, deflection is prone to occurring in the lubricating process, and the worker cannot conveniently and accurately lubricate the connecting position are solved.

    本发明提供地下运矿车自卸车箱与底盘连接结构,涉及矿山井下作业技术领域,包括底盘;所述车箱位于底盘的上方;所述连接组件共设有两组,且两组连接组件安装在底盘和车箱上;所述限位组件共设有两组,且两组限位组件安装在两组连接组件的内部;所述润滑组件共设有两组,且两组润滑组件安装在两组限位组件上;所述稳定组件安装在底盘和车箱上;所述定位组件共设有两组,且两组定位组件安装在稳定组件的前后两侧;本发明当工作人员向内按压润滑油挤压杆时,限位销轴内部的润滑油通过一个或多个润滑孔洞流出,实现精确润滑;解决润滑时工人需要通过外部润滑器械进行润滑,润滑过程中容易发生歪斜,不方便工人对连接处进行精确润滑的问题。
