The hoisting tool for the low-speed diesel engine cylinder cover nut comprises a horizontally-arranged flat circular ring, a plurality of symmetrically-arranged lifting lugs and a plurality of hollow cylinders corresponding to cylinder cover studs in position distribution are welded to the upper plane of the flat circular ring, and the hollow cylinders are used for containing the cylinder cover nut. The cylinder cover nut is fixed in an inner cavity of the hollow cylinder through a bolt and a nut, the lifting lug is connected with a lifting disc above through a steel wire rope, and the lifting disc is used for being connected with a lifting bolt of lifting equipment. The lifting equipment integrally lifts all cylinder cover nuts with single cylinders to the cylinder cover at a time through the lifting ring screws so as to carry out assembling operation. All cylinder cover nuts of a single cylinder are integrally hoisted at a time, the working efficiency is improved, repeated operation is reduced, potential safety hazards and potential quality hazards of operation are reduced, and the cylinder cover nut hoisting device has the advantages of being stable in hoisting, high in safety, good in stability, convenient to operate, low in cost and wide in application range.

    一种用于低速柴油机缸盖螺母的吊装工具和安装方法,包括一水平置放的平圆环,该平圆环的上平面焊接有多个对称布置的吊耳和若干与缸盖螺柱的位置分布相对应的空心圆柱,空心圆柱用于置放缸盖螺母,该缸盖螺母通过螺栓和螺母固定于该空心圆柱的内腔中,吊耳通过钢丝绳与上方的起吊盘连接,该起吊盘用于连接起重装备的吊环螺钉;起重装备通过该吊环螺钉将置放有单个气缸的所有缸盖螺母一次性整体起吊运至缸盖上,以进行装配作业。本发明实现了对单个气缸的所有缸盖螺母进行一次性整体起吊,提高了工作效率,减少了重复作业,降低了作业安全隐患和质量隐患,具有起吊平稳、安全性强、稳定性好、操作方便、成本低廉、适用范围广的优点。
