The quay crane pull rod motion constraint structure comprises an auxiliary tensioning pull rod composed of a first connecting rod, a second connecting rod and a third connecting rod which are sequentially connected through pin shafts, and a first clamping shaft is arranged at the end, facing the second connecting rod, of the first connecting rod; a second clamping shaft is arranged at one end of the third connecting rod towards the second connecting rod; a first clamping groove and a second clamping groove are formed in one end, facing the first connecting rod, of the second connecting rod; a third clamping groove is formed in the end, facing the third connecting rod, of the second connecting rod. Notches of the first clamping groove and the second clamping groove face the first clamping shaft, and through rotation between the first connecting rod and the second connecting rod, the first clamping groove and the second clamping groove make contact with the first clamping shaft to form backstops; the opening of the third clamping groove faces the second clamping shaft, and through rotation between the third connecting rod and the second connecting rod, the third clamping groove makes contact with the second clamping shaft to form a stopping block. According to the invention, the problem of possible deadlock caused by the movement of the front crossbeam in the unexpected reverse direction in the tilting process is avoided.

    本发明公开了一种岸桥拉杆运动约束结构,包括依次通过销轴连接的第一连杆、第二连杆与第三连杆组成的辅助张紧拉杆,第一连杆朝第二连杆的一端上设有第一卡轴;第三连杆朝第二连杆的一端上设有第二卡轴;第二连杆朝第一连杆的一端上设有第一卡槽、第二卡槽;第二连杆朝第三连杆的一端上设有第三卡槽;第一卡槽、第二卡槽的槽口均朝第一卡轴设置,通过第一连杆与第二连杆之间的转动,第一卡槽、第二卡槽分别与第一卡轴接触形成止挡;第三卡槽的槽口朝第二卡轴设置,通过第三连杆与第二连杆之间的转动,第三卡槽与第二卡轴接触形成止挡。本发明避免前大梁仰起过程中向非期望的反向方向运动,导致可能出现锁死的问题。
