The invention provides a ship unloader material receiving plate hoisting mechanism protection system. The ship unloader material receiving plate hoisting mechanism protection system comprises a material receiving plate, a winding drum and a traction rope, one end of the traction rope is connected with the material receiving plate, and the other end of the traction rope is wound on the winding drum. Baffles are further arranged on the two sides of the winding drum separately, and a stroke protection device is arranged between the two baffles and arranged at the position where the traction rope enters and exits the winding drum. The stroke protection device comprises a first swing arm, a second swing arm and a base, a limiting space facilitating passing of the traction rope is formed among the first swing arm, the second swing arm and the base, stroke switches are further arranged at the two ends of the first swing arm and the two ends of the second swing arm, and the first swing arm and the second swing arm are used for triggering the stroke switches. According to the scheme, the structure is simple, installation is easy and convenient, the material receiving plate is protected by a winding drum check ring, cam limiting, a steel wire rope stroke protection device, steel wire rope pulling force limiting and the like in the operation process, and the possibility that a steel wire rope is snapped when abnormal conditions exist, and consequently the material receiving plate falls is fundamentally eradicated.

    本发明提供了一种卸船机接料板卷扬机构保护系统,包括接料板、卷筒以及牵引绳,牵引绳一端与接料板连接,另一端缠绕在卷筒上;卷筒两侧还分别设有挡板,两个所述挡板之间还设有行程保护装置,行程保护装置设置在牵引绳进出卷筒部位;行程保护装置包括第一摆臂、第二摆臂和底座,第一摆臂、第二摆臂和底座之间形成便于牵引绳通过的限位空间,第一摆臂和第二摆臂两端还设有行程开关,所述第一摆臂和第二摆臂用于触发行程开关。本发明所述的方案结构简单,安装简便,接料板在运转时受到卷筒挡圈、凸轮限位、钢丝绳行程保护装置、钢丝绳拉力限制等多层次的保护,从根本上杜绝了存在异常情况时钢丝绳被拉断从而导致接料板发生坠落的可能性。
