The invention provides an underwater self-unhooking hoisting device, underwater hoisting equipment and a hoisting system, and belongs to the technical field of underwater hoisting, the underwater self-unhooking hoisting device is characterized in that a clamping section and a self-weight section form a lever structure, and the clamping section is clamped with a lifting hook body to limit a lifting frame of an object in a containing cavity; when the lifting hook body and the safety clamp are immersed in first liquid, due to the fact that the density of the floating device is smaller than that of the first liquid, the floating device floats on the liquid level of the first liquid, the self-weight section can rotate and be lifted upwards under lifting of the floating device, and meanwhile the clamping section rotates downwards; the locking state of the safety clamp to the containing cavity is relieved, the object hanging bracket can retreat from the containing cavity to be separated from the hanging hook, the safety clamp can automatically open the containing cavity under the liquid level of the first liquid by utilizing buoyancy of the first liquid to the floating device, unhooking of the hanging hook is completed, the hanging hook can be smoothly recycled underwater, and the underwater hanging difficulty is reduced.
本申请提供了一种水下自脱钩吊装装置、水下吊装设备和吊装系统,所属水下吊装技术领域,包括:卡定段与自重段构成杠杆结构,卡定段通过与吊钩本体卡接将物体的吊架限制在容纳腔内;自重段与漂浮装置通过连接绳连接,当吊钩本体和保险卡浸入第一液体内时,由于漂浮装置的密度小于第一液体的密度,漂浮装置漂浮在第一液体的液面上,自重段在漂浮装置的提拉下会向上转动抬起,同时卡定段向下转动,解除保险卡对容纳腔的锁闭状态,使物体吊架能够从容纳腔中退出与吊钩分离,利用第一液体对漂浮装置的浮力,使保险卡能够在第一液体的液面下自动开启容纳腔,完成吊钩脱钩,使吊钩在水下能够顺利回收,降低水下吊装难度。
