The invention provides a frequency-adjustable dynamic vibration absorber of a ship inclined ladder. Comprising an L-shaped connecting part, the L-shaped connecting part comprises two connecting shells which are vertically arranged, independent cavities are formed in the two connecting shells respectively, and an independent vibration control mechanism is arranged in each cavity. The vibration control mechanism comprises a connecting rod, a mass block, a spring and a plurality of damping holes. The connecting rods are connected with the two ends of the connecting shell, the mass block slides along the connecting rods, and the springs are arranged on the two sides of the mass block respectively. When the mass block reciprocates in the axis direction of the connecting rod, damping liquid filled in the cavities of the connecting shell flows between the two cavities through the damping holes. The vibration absorption device is arranged on the back face of the ship inclined ladder to absorb transverse and vertical vibration of the inclined ladder, the influence of abnormal vibration of the inclined ladder or a handrail on personnel use and structural safety is prevented, meanwhile, the occupied space is small, and normal use of the inclined ladder and the external space is not affected. The device is simple in structure, high in practicability, stable in structure and capable of meeting the requirement for stable use of the ship under the severe working condition that the ship shakes on the sea.

    本申请提供一种船舶斜梯的频率可调动力吸振器。包括L型连接部,L型连接部包括垂直设置的两个连接壳体,两个连接壳体内分别配置独立的空腔,每个空腔内设置独立的制振机构。制振机构包括连接杆、质量块、弹簧以及多个阻尼孔。连接杆与连接壳体的两端连接,质量块沿连接杆滑动,弹簧分别设于质量块的两侧。在质量块沿连接杆的轴线方向往复运动时,填充于连接壳体的空腔内的阻尼液经阻尼孔流动于两个空腔之间。本申请设于船舶斜梯的背面,以吸收斜梯的横向及垂向振动,防止斜梯或扶手的异常振动对人员使用及结构安全的影响的同时,占用空间小,不影响斜梯及外部空间的正常使用。本申请结构简单、实用性强,且结构稳定,能够满足船舶在海上摇晃的恶劣工况下稳定使用。
