The invention discloses a marine diesel engine cylinder sleeve vertical lifting sling which comprises a clamp combination, a clamp combination opening and closing locking mechanism, a lifting beam and a pair of lifting arms. The clamp combination comprises a fixed clamp and a movable clamp, one end of the fixed clamp is hinged to one end of the movable clamp, and the other end of the movable clamp is hinged to the lifting beam; the other end of the fixed clamp is connected with the other end of the movable clamp in a locking mode through a clamp combination opening and closing locking mechanism. Before the cylinder sleeve is vertically lifted, the fixed hoop and the movable hoop are closed and locked to enclose the cylinder sleeve, and at the moment, the upper side of a whole cylindrical surface formed by splicing the inner arc surface of the fixed hoop and the inner arc surface of the movable hoop abuts against the joint of the transition convex arc surface and the outer cylindrical surface of the middle section of the cylinder sleeve; the lower ends of the lifting arms are symmetrically and vertically welded and fixed on two sides of the outer cylindrical surface of the fixing hoop; two ends of the lifting cross beam are respectively welded with the upper ends of the corresponding lifting arms. The device is compact in structure, convenient and fast to use and low in manufacturing cost. And during hoisting, the cylinder sleeve does not generate overturning moment, so that the hoisting safety is ensured.
本发明公开了一种船用柴油机气缸套垂直起吊吊具,包括卡箍组合、卡箍组合开合锁定机构、起吊横梁和一对吊臂,卡箍组合包括固定卡箍和活动卡箍,固定卡箍一端与活动卡箍一端铰接,固定卡箍另一端与活动卡箍另一端通过卡箍组合开合锁定机构锁定连接。气缸套垂直起吊前,先将固定卡箍与活动卡箍闭合锁定围合住气缸套,此时固定卡箍内圆弧面与活动卡箍内圆弧面拼合成的整圆柱面上侧抵靠在气缸套中段过渡凸圆弧面与外圆柱面的连接处,吊臂下端对称垂直焊接固定在固定卡箍外圆柱面两侧上,起吊横梁两端分别与对应的吊臂上端焊连。本发明结构紧凑、使用方便快捷,制造成本低廉。起吊时,气缸套不会产生倾覆力矩,确保吊运安全。
