The invention discloses a mine car capable of being safely braked. The trolley comprises a trolley plate and wheels, a connecting base is fixed at the end part of the vehicle plate in the advancing direction; a moving rod is arranged below the vehicle plate; a rectangular frame is mounted at one end of the moving rod; the rectangular frame is sleeved on the connecting base of the vehicle plate; the end, away from the rectangular frame, of the movable rod is horizontally and rotationally connected with the ends, close to each other, of the two connecting rods. An included angle between the moving rod and the connecting rod is an acute angle; the middle parts of the two moving rods are connected through a first elastic part; sliding rods are horizontally and rotationally connected to the ends, away from each other, of the two connecting rods, fixing blocks are fixed to the positions, corresponding to the two sliding rods, of the bottom side of the trolley plate, the ends, facing the wheels, of the sliding rods penetrate through the fixing blocks and are slidably connected with the fixing blocks, and a plurality of limiting grooves matched with the sliding rods are formed in the innerside of the trolley plate. When a worker mistakenly takes off and hangs the plug pin or the plug pin is accidentally separated in the moving process of two adjacent vehicles, wheels are limited to rotate, vehicle sliding accidents are avoided, and potential safety hazards are reduced.

    本发明公开了一种安全制动的矿车,包括车板和车轮,车板前进方向的端部固定有连接座,车板的下方设有移动杆,移动杆的一端安装有矩形框,矩形框套在车板的连接座上,移动杆远离矩形框的一端分别与两个连接杆相靠近的一端水平转动连接,移动杆和连接杆的夹角为锐角,且两个移动杆的中部通过第一弹性件连接,两个连接杆相远离的一端均水平转动连接有滑动杆,车板底侧对应两个滑动杆的位置均固定有固定块,滑动杆朝向车轮的一端贯穿固定块并与固定块滑动连接,车板内侧开设有若干个与滑动杆适配的限位槽;工作人员错误摘挂插销或者相邻两车移动过程中插销意外脱离时,车轮被限制旋转,避免跑车事故的发生,降低安全隐患。
