The invention provides a mechanical self-locking bolt mechanism for a locking device of ship roll-on and roll-off equipment, which comprises a bracket, a hydraulic oil cylinder, a stop block, a bendable connecting rod mechanism and a bolt, and is characterized in that the bracket comprises an L-shaped plate and two side plates, and the two side plates are arranged on the two sides of the L-shaped plate in a mirror symmetry manner and are fixedly connected with the L-shaped plate; the central axis of the hydraulic oil cylinder inclines downwards relative to the vertical plate, and an oil cylinder shaft of the hydraulic oil cylinder stretches out and draws back between the two side plates. The plug pin is arranged on the lower portion between the two side plates and is parallel to a transverse plate in the L-shaped plate, the upper end of the bendable connecting rod mechanism is rotatably connected with the two side plates through pin shafts, the lower end of the bendable connecting rod mechanism is rotatably connected with the end, close to the vertical plate, of the plug pin, and the free end of a hydraulic oil cylinder shaft is connected with the two ends of the bendable connecting rod. The stop block is located between the two side plates. By the adoption of the mechanical self-locking bolt mechanism, even if the oil cylinder accidentally loses efficacy, the bolt cannot be pushed back, the effect of the locking device is prevented from being reduced, and navigation safety is guaranteed.
本发明提供了一种用于船舶滚装设备锁紧装置的机械自锁型插销机构,包括支架、液压油缸、止挡块、可弯折连杆机构和插销,支架包括L型板和两个侧板,两个侧板镜像对称设于L型板的两侧,与L型板固定连接;液压油缸的中心轴线相对竖板向下倾斜设置,液压油缸的油缸轴在两个侧板之间伸缩;插销置于两个侧板之间下部,与L型板中的横板平行设置,可弯折连杆机构的上端通过销轴与两个侧板可转动连接,可弯折连杆的下端与插销靠近竖板的一端可转动连接,液压油缸轴的自由端与可弯折连杆的两端之间连接,止挡块位于两个侧板之间。采用本发明的机械自锁型插销机构,即使油缸意外失效,插销仍无法回推,避免引起锁紧装置效力下降,保障航行安全。
