The invention discloses a dismounting type hoisting tool and hoisting method for a marine gearbox housing, and belongs to the field of maintenance of marine gearbox parts. According to the invention, the technical problems of complex operation and low working efficiency of hoisting the gear box housing during maintenance of the gear box due to the structural design of a ship body are solved. Pin holes are formed in the upper portion, the left side, the right side and the lower portion of the lifting hook, a lifting lug is arranged on the upper portion of an external gearbox housing, the lifting hook is detachably connected with the gearbox housing through a first pin shaft, pin holes are formed in the lower portion of the ring hook, and the lifting hook is detachably connected with the ring hook through a second pin shaft. The steel wire rope penetrates through the tackle, the other end of the steel wire rope is detachably connected with the ring hook, a pin hole is formed in the lower portion of the tackle, the tackle is detachably connected with the lifting hook through a third pin shaft, the tackle is in sliding connection with an external sliding way, and the tackle transversely slides through the external sliding way. Working steps are reduced, and working efficiency is improved. The device is used for installation and maintenance of marine equipment.

    一种船用齿轮箱罩壳拆装式起吊工具及起吊方法,属于船用齿轮箱零部件检修领域。本发明解决了由于船体结构设计,对齿轮箱进行维修时存在起吊齿轮箱罩壳的操作复杂,工作效率低的技术问题。吊钩的上部、左右两侧和下部均设置有销孔,外置的齿轮箱罩壳上部设置吊耳,吊钩与齿轮箱罩壳通过第一销轴可拆卸连接,环钩的下部设置有销孔,吊钩与环钩通过第二销轴可拆卸连接,钢丝绳的一端与倒链固定连接,钢丝绳穿过滑车且钢丝绳的另一端与环钩可拆卸连接,滑车的下部设置有销孔,滑车与吊钩通过第三销轴可拆卸连接,滑车与外置的滑道滑动连接,滑车通过外置的滑道实现横向滑动。减少工作步骤,提高工作效率。本发明用于船用设备安装维修。
