The invention discloses an auxiliary device and method for mounting through bolts of a marine diesel engine. The auxiliary device comprises two pieces of equilateral angle steel, a rubber gasket, a plurality of connecting bolts and a plurality of connecting nuts. Each equilateral angle steel comprises a vertical edge and a horizontal edge which are symmetrically arranged on the two sides of the corresponding penetrating bolt, the horizontal edges are placed on the upper plane of the air cylinder body, the rubber gaskets adhere to the vertical edges of the equilateral angle steel, and the two equilateral angle steel are clamped on the penetrating bolts at the hoops through the connecting bolts and the connecting nuts; during installation, the through bolt is hoisted by the large crane, the through bolt is placed on the upper plane of the air cylinder body through the auxiliary device and stays in the through bolt hole, then the large crane is replaced by the wall crane to be connected with the through bolt, the auxiliary device is detached, and the wall crane is utilized to continue to complete subsequent installation operation. According to the method, the problem of labor hour waste caused by overhigh load of large driving is solved, and the effects of optimizing the operation method, reasonably utilizing equipment resources, reducing labor hour waste and improving the through bolt mounting operation efficiency are achieved.

    一种用于船用柴油机贯穿螺栓安装的辅助装置及方法,辅助装置包括两根等边角钢、橡胶垫片、若干连接螺栓和连接螺母;等边角钢包括有竖直边和水平边,对称地设置于贯穿螺栓的两侧,水平边搁置于气缸体的上平面上,橡胶垫片粘附在等边角钢的竖直边上,两根等边角钢通过连接螺栓和连接螺母夹紧于抱箍处的贯穿螺栓上;先用大行车吊起贯穿螺栓,通过辅助装置将贯穿螺栓搁置于气缸体的上平面上且停留在贯穿螺栓孔中,然后用墙壁吊替换大行车与贯穿螺栓连接,卸除辅助装置,再利用墙壁吊继续完成后续的安装作业。本发明解决了大行车负荷过高导致工时浪费的问题,达到了优化作业方法、合理利用设备资源、减少工时浪费、提升贯穿螺栓安装作业效率的效果。
