The invention discloses a marine diesel engine parking device which comprises a roller assembly, an upper sleeve, a connecting rod, an upper moving cylinder, a middle cylinder cover, a lower cylinder sleeve, a lower plunger and a support, the lower plunger is embedded into a counter bore of the lower cylinder sleeve, the middle cylinder cover seals the top of the lower cylinder sleeve, and the upper sleeve, the middle cylinder cover and the lower cylinder sleeve are fixedly connected into a whole. The upper end of the connecting rod is screwed into the center of the bottom of the upper moving column, and the lower end of the connecting rod penetrates through the middle cylinder cover and is screwed into the upper end of the lower plunger. The compressed air input channel comprises a vertical input hole and a horizontal output blind hole, and the compressed air control channel comprises a lower vertical hole, a lower horizontal output hole and a stop electromagnetic valve. According to the invention, the major accident that the marine diesel engine is out of control due to the fact that the rack is blocked and cannot push the rack pull rod is avoided, the reliability and safety of the marine diesel engine are improved, the marine diesel engine is stopped quickly and accurately, and the ship navigation safety is ensured.
本发明公开了一种船用柴油机停车装置,包括滚轮组件、上套筒、连接杆、上移动柱体、中缸盖、下缸套、下柱塞和支架,下柱塞嵌入下缸套沉孔中,中缸盖封闭住下缸套顶部,上套筒、中缸盖和下缸套固定连接成一体。连接杆上端拧入上移动柱底部中心,下端穿过中缸盖拧入下柱塞上端中,下缸套内还分别设有压缩空气输入通道及压缩空气控制通道。压缩空气输入通道包括垂直输入孔和水平输出盲孔,压缩空气控制通道包括下垂直孔、下水平输出孔和停车电磁阀。本发明避免发生因齿条出现卡滞无法推动齿条拉杆而导致船用柴油机失控的重大事故,提高了船用柴油机的可靠性和安全性,快速、精准地完成船用柴油机停车,确保船舶航行安全。
