The invention relates to a ship shafting temporary locking device which comprises a threaded sheath, a lock shaft sliding block, a sliding rail and a support, the sliding rail is installed on the support, the lock shaft sliding block is installed on the sliding rail in a sliding mode, and the lock shaft sliding block can linearly move along the sliding rail; a limiting hole corresponding to the threaded sheath is formed in the shaft locking sliding block, the threaded sheath is used for being installed on a bolt of a shaft system flange, and the threaded sheath is provided with an inner screw hole in threaded fit with the bolt. And after the lock shaft sliding block moves along the sliding rail, the threaded sheath is sleeved with the limiting hole. The temporary locking device for the ship shafting is installed on a bolt of a ship shafting flange in a matched mode through the threaded sheath, the shaft locking sliding block is arranged outside the threaded sheath in a sleeving mode through the limiting hole after moving along the sliding rail, on one hand, temporary locking of the ship shafting is achieved, and on the other hand, external threads of the bolt can be protected.
本发明涉及一种船舶轴系临时锁紧装置,包括螺纹护套、锁轴滑块、滑轨、支撑,滑轨安装在支撑上,锁轴滑块滑动安装在滑轨上,锁轴滑块可沿滑轨直线移动;锁轴滑块上对应螺纹护套设有限位孔,螺纹护套用以安装在轴系法兰的螺栓上,螺纹护套设有与螺栓螺纹配合的内螺孔;锁轴滑块沿滑轨移动后限位孔套住螺纹护套的外部。本发明的船舶轴系临时锁紧装置通过螺纹护套配合安装在船舶轴系法兰的螺栓上,锁轴滑块沿滑轨移动后通过限位孔套设在螺纹护套的外部,一方面实现对船舶轴系的临时锁紧,另外一方面还可以起到对螺栓外部螺纹的保护。
