The invention relates to the technical field of mine trolley, and discloses a mine trolley anti-stall device which comprises a trolley bottom plate, a trolley hopper is arranged on the upper surface of the trolley bottom plate, two wheel axles are movably installed on the lower surface of the trolley bottom plate, and the two wheel axles comprise the front axle and the rear axle. The outer side of the rear axle is fixedly sleeved with a driving chain wheel, and two inverted hanging L-shaped rods are fixedly installed at the positions, corresponding to the driving chain wheel, of one side of the car hopper. According to the anti-stall device for the mine trolley, by arranging the driven wheel, the pressing blocks, the extending blocks, the pushing blocks, the outer driving wheel, the trapezoidal pushing blocks, the inverted triangular blocks and other structures, when the outer side of the outer driving wheel makes contact with the speed reduction wheel rotating clockwise, and the next pressing block makes contact with the extending blocks, the process can be repeated, and the snub braking effect is achieved; therefore, the effect of automatically reducing the speed when the vehicle speed is too high is achieved, and the problem that the vehicle body is unstable due to sudden large-amplitude speed reduction is avoided through snub braking.

    本发明涉及矿道小车技术领域,且公开了一种矿道小车防失速装置,包括小车底板,所述小车底板的上表面设置有车斗,所述小车底板的下表面活动安装有两个车轮轴,两个所述车轮轴包括前车轴和后车轴,所述后车轴的外侧固定套接有驱动链轮,所述车斗的一侧且于驱动链轮的对应位置固定安装有两个倒悬L型杆。该矿道小车防失速装置,通过设置从动轮、施压块、延伸块、推动块、外动轮、梯形推块和倒三角块等结构,当外动轮的外侧接触到顺时针转动的减速轮时,当下一个施压块接触到延伸块时,会重复上述流程,达到点刹的效果,从而达到了车速过快时可以自动减速的效果,且通过点刹避免了突然大幅度减速造成车身不稳的问题。
