The invention relates to the technical field of ship and ocean engineering, and discloses an LNG liquid cargo pump cabin inner limiting device which comprises fixing tables arranged on the two sides of a circular surrounding wall at the bottom of a pump tower. The limiting device is suitable for limiting and fixing the cargo hold liquid cargo pump. The structure design is novel, under the effect of the angle aluminum, the liquid cargo pump is effectively prevented from jumping in the X direction and the Y direction, the liquid cargo pump can freely move in the Z direction, and it is effectively guaranteed that a cargo barge system shrinks and sinks due to LNG filling. According to the design, the original structural form of the pump tower is fully utilized, the influence of vibration of the cargo pump on the pump tower structure is reduced as much as possible, and fatigue damage of the pump tower structure caused by vibration transmission is avoided; a worker can conveniently change the position of the angle aluminum in the X direction or the Y direction, so that after the fixing table is fixed, the angle aluminum is still suitable for liquid cargo pumps in different directions, and the applicability is high.

    本发明涉及船舶与海洋工程技术领域,且公开了一种LNG液货泵舱内限位装置,包括设置于泵塔底部圆形围壁两侧的固定台;本发明适用货舱液货泵的限位固定。其结构设计新颖,并且在角铝的作用下,不仅有效的防止液货泵在X方向和Y方向的跳动,还可使其在Z向自由活动,有效的保证了货驳系统因LNG加注产生收缩下沉运动。该发明设计充分利用泵塔原结构形式,尽可能的降低因货泵振动带给泵塔结构的影响,避免泵塔结构因振动传递而产生疲劳损伤,此外可以在传动机构、第一调节机构、夹持机构以及第二调节机构的作用下,便于工作人员改变角铝X方向或Y方向的位置,进而在固定台固定后,使得角铝依然适用于不同方位的液货泵,适用性强。
