The invention belongs to the technical field of hoisting equipment, and discloses a lifting hook and a crane, the lifting hook comprises a lifting hook body and a sealing assembly, the lifting hook body is provided with an opening, one side edge of the opening is a connecting part of the lifting hook body, and the other side edge is a hook head of the lifting hook body. The sealing assembly comprises a sealing piece, a torsion spring, a locking structure and an unlocking triggering structure. One end of the sealing piece is rotationally connected to the connecting part, and the other end can abut against the hook head. The torsion spring is connected with the sealing piece and the lifting hook body. The sealing piece is provided with a containing cavity, the containing cavity penetrates through one end of the sealing piece, and the locking structure is arranged in the containing cavity. The unlocking triggering structure comprises a limiting piece, and the limiting piece is arranged in the containing cavity in a position-adjustable mode. When the other end of the sealing piece abuts against the hook head, the locking structure is supported between the connecting part and the limiting piece which are oppositely arranged, so that the sealing piece is prevented from rotating relative to the connecting part, the opening is tightly sealed, the safety is good, and a heavy object hung on the lifting hook body is not prone to disengaging from the opening.

    本发明属于起重设备技术领域,公开了一种吊钩及起重机,包括吊钩本体和封口组件,吊钩本体上设置有开口,开口的一侧边缘为吊钩本体的连接部,另一侧边缘为吊钩本体的钩头。封口组件包括封口件、扭转弹簧、锁定结构和解锁触发结构。封口件的一端转动连接于连接部,另一端能够抵靠于钩头。扭转弹簧连接封口件和吊钩本体。封口件设置有容置腔,容置腔贯通封口件的一端,锁定结构设置于容置腔内。解锁触发结构包括限位件,限位件位置可调地设置于容置腔内。封口件的另一端抵靠于钩头时,锁定结构支撑于相对设置的连接部和限位件之间,从而阻碍封口件相对于连接部的转动,使得开口封闭严密,安全性好,挂设于吊钩本体上的重物不易从开口处脱出。
