The invention discloses a lifting device and a lifting method for a main bearing cover of a marine diesel engine. The lifting device comprises a pulley fixing device, a main bearing cover fixing device and a sling, wherein the pulley fixing device is fixedly connected to the lower portion of a transverse web in a crankcase of the marine diesel engine, the main bearing cover fixing device is fixed to the upper plane of a main bearing cover, a lifting hook at the lower end of the sling is connected with the main bearing cover fixing device, and the upper end of the sling penetrates through the pulley fixing device and is connected with hoisting equipment outside the crankcase; and after the hydraulic stud is loosened, the lifting device lifts and lifts the main bearing cover and moves the main bearing cover out of the crank case. When a main bearing part in the crankcase of the marine diesel engine is overhauled, the main bearing cover can be conveniently, safely and reliably lifted and moved out of the crankcase, and the effects that operation is easy, the working efficiency is improved, parts are protected, the quality of a main engine is improved, and safety risks are reduced are achieved.

    一种船用柴油机主轴承盖的起吊装置及起吊方法,包括滑轮固定装置、主轴承盖固定装置和吊索;其中,滑轮固定装置固定连接于船用柴油机曲柄箱内的横腹板的下部,主轴承盖固定装置固定于主轴承盖的上平面上,吊索下端的吊钩与该主轴承盖固定装置连接,上端穿过滑轮固定装置且与曲柄箱外的起重设备连接;在液压螺柱松开后,起吊装置对主轴承盖进行提升起吊且将该主轴承盖移至曲柄箱之外。本发明在船用柴油机曲柄箱内主轴承部件检修作业时,能够便捷、安全、可靠地将主轴承盖起吊移动至曲柄箱外,达到了易于操作、提升作业效率、保护零部件、提升主机质量、降低安全风险的效果。
