The invention discloses an emergency braking device for a monorail crane. The emergency braking device comprises two symmetrically-arranged braking arms, two braking wheel assemblies, a spring assembly and a lock shaft. The brake arm and the brake wheel assembly which are driven by energy storage of the spring assembly are arranged, the lock shaft is designed for limiting, one end of the lock shaft is provided with the fixed limiting plate, the other end of the lock shaft is provided with the trigger limiting plate, and in an emergency situation, an operator in a cab controls the trigger limiting plate to trigger, so that one end of the lock shaft is not restrained, and the lock shaft is locked. Under the action of the spring assembly, the brake wheel assemblies at the tops of the two brake arms are driven to be clamped with a rail, braking under the emergency situation is achieved, the structure serves as a standby brake structure when the monorail hoist fails in braking, and the use safety of the monorail hoist can be improved.
本发明公开了一种单轨吊紧急制动装置,包括:两个对称设置的制动臂、两个制动轮组件、弹簧组件以及锁轴。本发明,通过设置由弹簧组件蓄能进行驱动的制动臂与制动轮组件,并设计了锁轴进行限制,锁轴的一端具有固定限制板,另一端具有触发限制板,遇到紧急情况的时候,驾驶舱的操作人员控制触发限制板触发,使锁轴的一端不被约束,在弹簧组件的作用下,驱动两个制动臂的顶部的制动轮组件与轨道进行夹持,实现紧急情况下的刹车,该结构作为单轨吊车刹车失效时的备用刹车结构,能够提高单轨吊车的使用安全性。
