The invention relates to a car stopping device and an underground coal mine rail transportation system. The car stopping device comprises a mounting part, a rotating plate, a driving part and a stopping assembly, the rotating plate is provided with a passing end and a stopping end, and the rotating plate is rotatably arranged on the mounting part and has a passing position and a stopping position; the driving piece drives the rotating plate to move between a passing position and a blocking position; the blocking assembly comprises a fixing frame, an elastic piece and a protective net, the fixing frame is arranged at the blocking end of the rotating plate, the protective net is connected with the fixing frame through the elastic piece, and the protective net and the mine car are opposite in the extending direction of the rail at the blocking position. According to the car stopping device, when the tramcar is out of control, the driving piece drives the stopping assembly to move to the stopping position, elastic contact with the tramcar is formed through the protective net and the elastic piece, the impact force of the tramcar is weakened, the collision force of the tramcar is reduced, rigid collision of the tramcar is avoided, and car sliding accidents are effectively avoided; and the transportation safety of the mine car is improved.

    本发明涉及一种阻车装置及煤矿井下轨道运输系统。阻车装置包括安装件、旋转板、驱动件和阻挡组件,旋转板具有通行端和阻挡端,旋转板可转动地设在安装件上且具有通行位置和阻挡位置;驱动件带动旋转板在通行位置和阻挡位置之间移动;阻挡组件包括固定框、弹性件和防护网,固定框设在旋转板的阻挡端上,防护网通过弹性件与固定框相连,在阻挡位置,防护网与矿车在轨道的延伸方向上相对。本发明的阻车装置,当矿车失控时,驱动件带动阻挡组件移动至该阻挡位置,通过防护网和弹性件形成与矿车的弹性接触,削弱了矿车的冲击力,减轻了矿车的冲撞力,避免矿车发生刚性碰撞,并有效避免发生跑车事故,提升了矿车运输的安全性。
