The invention discloses a large-marine diesel engine cylinder cooling water jacket dismounting assembly and dismounting method. The dismounting assembly comprises a hard rubber pipe and a limiting block, and the dismounting method comprises the steps of cylinder cover pre-hoisting, replacement of a cooling water pipe with the hard rubber pipe, limiting block placement, cylinder cover lowering, cylinder cover moving and hoisting and water jacket hoisting. The assembly and method have the characteristics of being uniform in stress, and convenient, quick and safe in operation. Due to the fact that when an air cylinder cover is pressed downwards, fixing bolts of the air cylinder cover can play a guiding role, the air cylinder cover can be kept horizontal when pressed downwards, it is guaranteed that the hard rubber pipe is evenly stressed, and construction safety is guaranteed. Meanwhile, due to the fact that more tools and operation steps do not need to be added, operation is convenient. For a large-marine diesel engine, due to the fact that the dead weight of the air cylinder cover is large, compared with hammering, hoist pulling-down and other methods, the method for dismounting a cooling water jacket is faster and more efficient.

    本发明公开了一种大型船用柴油机气缸冷却水套拆除组件及拆除方法,拆除组件包括硬质橡胶管和限位块,拆除方法包括缸盖预吊装、冷却水管更换硬质橡胶管、放置限位块、下放气缸盖、移吊缸盖、和吊装水套,本发明具有受力均匀,操作方便、快捷、安全的特点。因为气缸盖往下压时,气缸盖的固定螺栓能起到导向作用,因此气缸盖下压时能保持水平,保证硬质橡胶管受力均匀,确保了施工安全。同时,因为本发明无需增加较多的工具工装和操作步骤,所以操作起来也比较方便。对于大型船用柴油机,因其气缸盖自重较大,所以使用本发明对冷却水套拆除较之锤击和葫芦下拉等方法也更为快捷高效。
