The invention discloses an overturning device and method for a marine diesel engine air cylinder cover. The overturning device is cooperated with a single lifting hook to operate; in an air cylinder cover downward-lifting process, the lifting point of the single lifting hook deviates from the center of gravity of the air cylinder cover to form lateral overturning torque; and then, by use of a characteristic that a rotation component can swing on the ground, the air cylinder cover realizes lateral turning and overturning in virtue of the rotation of the rotation component. The overturning device comprises the rotation component and skids, wherein the rotation component is provided with a bottom part of a curved surface shape and comprises three ribbed plates, a bottom plate, two vertical frames, two supporting idler wheels, an installation shaft, a supporting bottom plate and a supporting baffle plate, wherein the bottom outline of each ribbed plate is of a curve shape, and the three ribbed plates are vertical and are laterally arranged in parallel; the shape of the bottom plate and the bottom outline of each ribbed plate are the same, and the bottom plate and the ribbed plates arewelded and fixed; the two vertical frames are independently laminated to the outer sides of the ribbed plates on two sides, and the lower parts of the two vertical frames are fixed with the ribbed plates; the supporting idler wheels are erected on the upper parts of the two vertical frames through the installation shaft and can rotate; and the rotation component is placed and can swing between left and right on the ground. The overturning device is easy in operation and is high in working efficiency, operation safety is greatly improved, and accident risks are avoided.

    一种船用柴油机气缸盖的翻身装置和方法,采用翻身装置与单吊钩配合作业,在气缸盖下吊过程中,使单吊钩的吊点与气缸盖的重心错开,形成侧翻转矩,再利用转动组件在地面上能够摆动的特性,使气缸盖借助该转动组件的转动,实现侧转翻身;翻身装置包括转动组件和垫木,转动组件具有曲面形的底部,包括三肋板、底板、两立架、两支撑滚轮、安装轴、支撑底板和支撑挡板;三肋板的底部轮廓为曲线形,竖立且平行地横向设置,底板形状与肋板底部轮廓相同且与之焊固,两立架分别贴合于两侧肋板的外侧,下部与该肋板固定,支撑滚轮通过安装轴架设于两立架的上部且能够转动,转动组件放置且能够在地面上左右摆动。本发明操作容易,工作效率高,大幅提高了作业的安全性,避免了事故风险。
