The invention provides a propeller dismounting method, a mounting method and a dismounting tool. The propeller dismounting method comprises the following steps that a locking nut of a propeller to bedismounted is rotated until the locking nut is separated from the propeller; the propeller is loosened to enable a propeller hub of the propeller and the tail shaft to be in a clearance fit state; a hoisting point is preset between a set of adjacent blades on the propeller, and the propeller is rotated so that the hoisting point can be located over the propeller; the propeller is supported througha moving trolley, and the moving trolley is moved to enable the propeller to leave the ship body; a paddle adjacent to the hoisting point is bound to the hoisting point; and the propeller is hoistedthrough the hoisting point, and the propeller is lowered to a designated position. According to the propeller dismounting method, the propeller is moved through the moving trolley, so that the propeller can be dismounted stably, conveniently and quickly, welding of lifting lugs is avoided, and the propeller is prevented from being suspended during dismounting.

    本发明提供一种螺旋桨拆卸方法、安装方法及拆装工装,所述螺旋桨拆卸方法包括以下步骤:旋转待拆卸螺旋桨的锁紧螺母直至所述锁紧螺母脱离所述螺旋桨;松动所述螺旋桨使所述螺旋桨的桨毂和所述尾轴处于间隙配合状态;预设一起吊点在所述螺旋桨上一组相邻的桨叶之间,旋转所述螺旋桨,以使所述起吊点位于所述螺旋桨的正上方;通过移动小车支撑起所述螺旋桨,移动所述移动小车以使所述螺旋桨离开船体;将与所述起吊点相邻的桨叶绑扎到所述起吊点;经所述起吊点吊起所述螺旋桨,将所述螺旋桨下放到指定位置。本发明的螺旋桨拆卸方法通过移动小车来移动螺旋桨,使得螺旋桨能够平稳拆卸,方便快捷,免除焊接吊耳,并且避免了螺旋桨拆除时悬空。
