The invention discloses a brake device for a rail line flatcar, which comprises a flatcar frame (3) and a flatcar wheel pair (4), lever force transmission structures (1) are respectively mounted on the front side and the rear side of the flatcar frame (3), fulcrums of the lever force transmission structures (1) are fixed on the flatcar frame (3), brake friction plates (2-2) are mounted at the lower ends of levers, and the brake friction plates (2-2) are fixed on the flatcar wheel pair (4). When the upper end of the lever rotates outwards, the brake friction plate (2-2) moves towards the small flatcar wheel pair (4), and when the upper end of the lever rotates inwards, the brake friction plate (2-2) is far away from the small flatcar wheel pair (4). By reversely pulling the detachable push rod, the friction force of contact between the brake friction plate and the wheel pair is provided and increased, and manpower actively intervenes in braking; the detachable push rod is pushed in the forward direction to limit contact between the brake friction plate and the wheels and provide thrust, running of the trolley is achieved, and the problem of braking of the trolley in a traditional line is effectively solved.
本发明公开了一种轨道线路小平车使用的刹车装置,包括小平车架(3)及小平车轮对(4),小平车架(3)的前后两侧分别安装有杠杆传力结构(1),杠杆传力结构(1)的支点固定在小平车架(3)上,杠杆下端安装刹车摩擦片(2‑2),杠杆上端向外转动时刹车摩擦片(2‑2)向小平车轮对(4)运动,杠杆上端向内转动时刹车摩擦片(2‑2)远离小平车轮对(4)。通过反向拉可拆卸推杆,提供并增大刹车摩擦片和轮对接触的摩擦力,实现人力主动介入刹车;通过正向推可拆卸推杆限制刹车摩擦片和轮的接触并提供推力,实现小平车的行驶,有效解决了传统线路小平车制动的问题。
