本机构通过成对对称固定在桥体上的扇形块,在随桥体同步摆动时,受到固定在轴端的限位板限制而实现车桥摆动的限位,有效避免桥的随机摆动带来的所有隐患。
Through symmetrical pairs of segments fixed on the bridge body, the mechanism can limit the swing of the axle by the limit plate fixed at the axle end when synchronously swinging with the bridge body, so as to effectively avoid the random swing of the bridge All hidden dangers.
