The invention relates to the technical field of diesel engines, and discloses a main bearing cap dismounting structure which comprises a diesel engine body, a main bearing cap body is arranged in the diesel engine body, and first lifting holes corresponding in position are formed in the front face and the back face of the right side of the main bearing cap body. Through cooperation of the main bearing cover body, a jacking hydraulic cylinder, a first extension rod and a first lifting bolt, the action of vertical movement of the main bearing cover body is achieved through movement of the jacking hydraulic cylinder, and the effect of disassembling and assembling the main bearing cover body is achieved; the problem that the main bearing cover body is limited by space and is inconvenient to disassemble and assemble is effectively solved, the main bearing cover body jacking mode is adopted, the main bearing cover body disassembling and assembling steps are simplified, the main bearing cover body disassembling and assembling workload of workers is relieved, and therefore maintenance work of a diesel engine body is facilitated.

    本发明涉及柴油机技术领域,且公开了一种主轴承盖拆装结构,包括柴油机本体,所述柴油机本体的内部设置有主轴承盖本体,所述主轴承盖本体右侧的正面和背面开设有位置相对应的一号起吊孔。本发明通过主轴承盖本体、顶升液压缸、一号接长杆和一号吊环螺钉之间的配合,利用顶升液压缸的运动,实现了主轴承盖本体的竖直方向运动的作用,达到了对主轴承盖本体拆装的效果,有效地解决了主轴承盖本体受到空间限制不便拆装的问题,采用主轴承盖本体的顶升的方式,简化了主轴承盖本体的拆装的步骤,减轻了工作人员对主轴承盖本体拆装的工作量,从而便于对柴油机本体的检修工作。
