The mining rail trolley with the stall protection function comprises a trolley box and rail wheels, a mounting frame is welded to the lower surface of the trolley box, a fixedly-mounted shaft is fixedly mounted in the mounting frame, the rail wheels are rotatably mounted at the two ends of the fixedly-mounted shaft, damping speed limiting boxes are fixedly mounted at the two ends of the fixedly-mounted shaft, and the damping speed limiting boxes are fixedly mounted at the two ends of the fixedly-mounted shaft. The damping speed-limiting box is located on the inner side of the rail wheel, and the rail wheel is in power connection with the damping speed-limiting box. The transportation function of the foundation is achieved through a carriage of the foundation and rail wheels, a damping speed limiting box is fixedly installed on a fixed installation shaft so that the device can conduct passive speed limiting, the passive speed limiting device drives a movable carrying disc through an internal centrifugal swing frame, the movable carrying disc moves close to a fixed carrying disc relatively, and the movable carrying disc is driven to move close to the fixed carrying disc. And then the movable friction ring makes contact with the fixed friction ring, friction braking is conducted, and therefore speed limiting and braking of the device are achieved.

    本发明公开了一种带有失速保护的矿用轨道小车,包括车箱与轨道轮,所述车箱的下表面焊接有安装架,所述安装架内固定安装有定装轴,所述轨道轮转动安装于定装轴的两端,所述定装轴的两端固定安装有阻尼限速盒,所述阻尼限速盒位于轨道轮的内侧,所述轨道轮与阻尼限速盒动力连接;通过基础的车箱与轨道轮实现基础的运输功能,而在定装轴上固定安装有阻尼限速盒使得装置能够进行被动限速,被动限速装置,通过内部离心摆架对移动载盘进行驱动,移动载盘以此与定载盘进行相对靠近移动,继而使得移动摩擦环与定摩擦环接触,进行摩擦制动,从而实现装置的限速与制动。
