A disclosed emergency braking type mine car comprises a bottom plate, a car hopper is fixedly installed on the bottom plate, a plurality of connecting bases are fixedly connected to the bottom of the bottom plate, rotating rods are rotationally arranged between the connecting bases, the two ends of each rotating rod are fixedly connected with walking wheels, braking cavities are fixedly connected to the inner walls of the connecting bases, and the rotating rods are rotationally arranged in the braking cavities; a brake ring is fixedly connected into the brake cavity, and a heat insulation layer is arranged between the brake ring and the outer wall of the brake cavity. Compared with the prior art, under the condition of chain disengaging or rope breaking, the rotating speed of the rotating rod is increased, the internal centrifugal force can be increased while the rotating speed is increased, the telescopic rod can move outwards under the action of the centrifugal force, abut against the surface of the brake ring and generate friction with the rubber layer, and the rotating speed of the rotating shaft is slowly reduced; the running speed of the mine car can be reduced before emergency braking, and the situation that the mine car overturns and is damaged due to the fact that the running speed of the mine car is too high during emergency braking is avoided.

    本发明公开了一种可紧急制动式矿车,包括底板,底板上固定安装有车斗,底板底部固定连接有多个连接座,连接座间转动设有转杆,转杆两端固定连接有行走轮,连接座内壁上固定连接有制动腔室,转杆转动设置在制动腔室内,制动腔室内固定连接有制动环,制动环与制动腔室外壁间设有隔热层;与现有技术相比,本发明在脱链或者断绳的情况下,转杆的转速提高,在转速提高的同时,内部的离心力也会增加,伸缩杆能够在离心力的作用下向外移动,与制动环表面相抵,与橡胶层之间产生摩擦,慢慢降低转轴的转速,能够在紧急制动前降低矿车的运行速度,避免紧急制动时矿车的运行速度过快导致翻车的情况出现,导致矿车损坏。
