The invention discloses a single-cylinder bolt mechanism and a crane, the single-cylinder bolt mechanism comprises a structure main body and a driving mechanism, a cylinder pin and a cylinder pin groove plate are arranged on the structure main body, a cylinder pin shifting fork on the cylinder pin is inserted into a guide groove of the cylinder pin groove plate, and when the driving mechanism drives the cylinder pin groove plate to move left and right, the cylinder pin shifting fork is inserted into the guide groove of the cylinder pin groove plate. The cylinder pin stretches out and is inserted into a cylinder pin hole in the tail of the arm barrel or retracts into the structure body, a pair of first working faces and a pair of second working faces are arranged on the circumferential face of the end of the cylinder pin, the cylinder pin rotates around the axis of the cylinder pin while stretching out, and the working face in contact fit with the cylinder pin hole is switched from the second working face to the first working face. A smaller fit clearance is formed between the first working surface and the cylinder pin hole; the crane comprises the single-cylinder bolt mechanism. According to the invention, the problem of jitter impact caused by the clearance between the cylinder pin hole and the cylinder pin during arm retraction starting can be improved.

    本发明公开了一种单缸插销机构及起重机,该单缸插销机构包括结构主体和驱动机构,结构主体上设有缸销和缸销槽板,缸销上的缸销拨叉插入缸销槽板的导向槽中,当驱动机构驱使缸销槽板左右移动时,缸销伸出并插入臂筒尾部的缸销孔或者缩回结构主体内,缸销端部周向面上具有一对第一工作面和一对第二工作面,缸销伸出的同时还绕自身轴线转动,将与缸销孔接触配合的工作面由第二工作面切换为第一工作面,第一工作面与缸销孔间具有更小的配合间隙;所述起重机包括所述的单缸插销机构。本发明能够改善因缸销孔与缸销间隙导致的缩臂启动抖动冲击问题。
