The invention relates to the technical field of ship manufacturing, and discloses an automatic detection device for preventing a propeller rotating shaft from being fractured on a ship, which comprises a box body, screw rods are movably connected to the top and the bottom in the box body, and movable blocks are movably connected to the left ends and the right ends of the screw rods; fixed blocks are movably connected to the left end and the right end of the screw and located on the inner sides of the movable blocks, and first connecting rods are movably connected to the inner sides of the movable blocks and the fixed blocks. According to the automatic detection device for preventing the propeller rotating shaft from being broken on the ship, the rotating shaft drives a push plate to move, the push plate drives a fourth gear through a push rod and a second connecting rod, the fourth gear drives a third gear to rotate through gear teeth, the third gear drives a rotating rod, the rotating rod drives a knocking hammer to rotate, and the knocking hammer drives a rocker to rotate; the rocker drives the second gear to rotate, the second gear drives the turntable to rotate, and vibration or offset generated after the rotating shaft is broken is monitored, so that the automatic detection function is realized, the equipment reliability is improved, and the production cost is reduced.

    本发明涉及船舶制造技术领域,且公开了一种用于船舶上防止螺旋桨转轴断裂的自动检测装置,包括箱体,所述箱体内部顶部和底部均活动连接有螺杆,螺杆左端和右端均活动连接有活动块,螺杆左端和右端且位于活动块内侧活动连接有固定块,活动块和固定块内侧均活动连接有第一连杆。该用于船舶上防止螺旋桨转轴断裂的自动检测装置,通过转轴带动推板移动,推板通过推杆和第二连杆带动第四齿轮,第四齿轮通过轮齿带动第三齿轮旋转,第三齿轮带动转杆,转杆带动敲击锤旋转,敲击锤带动摇杆转动,摇杆带动第二齿轮旋转,第二齿轮带动转盘旋转,通过监测转轴断裂后产生的振动或偏移,实现自动检测功能,提高设备可靠性,降低生产成本。
