The invention discloses a multi-brake small rail car which comprises a car body 2, a front rail wheel 12 and a rear rail wheel 11, a circle of limiting columns are arranged on the side end face of the rear rail wheel 11, and during braking, an insertion brake pull rod 16 is inserted into gaps between the limiting columns to achieve braking. The front rail wheel 12 is braked by a brake pad 21, the brake pad 21 is installed at the front end of a brake sticking pull rod 17, the brake sticking pull rod 17 and a brake inserting pull rod 16 are both hinged to a transmission shaft 13, the brake sticking pull rod 17 and the brake pad 21 are controlled to be close to or away from the rail wheels through rotation of the transmission shaft 13, and the time that the brake pad 21 acts on the front rail wheel 12 is earlier than the time that the brake inserting pull rod 16 is inserted into the rear rail wheel 11. According to the trolley, multiple braking means are arranged on the trolley body, so that safe use of the trolley is achieved, compared with a traditional trolley, the trolley is better in stability and reliability, the trolley can be used on rail lines with different curves and gradients by adopting the multiple braking means, and safety in the construction process is also guaranteed.
本发明公开了一种多重制动轨道小车,包括车体2、前轨道轮12和后轨道轮11,后轨道轮11的侧端面上有一圈限位柱,制动时插刹拉杆16插入限位柱之间的间隙中实现制动;前轨道轮12采用刹车片21制动,刹车片21安装在贴刹拉杆17前端,贴刹拉杆17和插刹拉杆16均铰装在传动轴13上,通过通过传动轴13转动控制贴刹拉杆17和刹车片21靠近或者远离轨道轮,刹车片21作用于前轨道轮12的时间先于插刹拉杆16插入后轨道轮11。本发明通过在车体上设置多重制动手段从而实现小平车的安全使用,相比传统小平车,稳定性和可靠性更好,采用多重制动手段,能够在不同曲线、坡度的轨道线路上使用,也保障了施工过程中的安全。
