The invention relates to the technical field of ship construction, in particular to a tool for prefabricating an outlet pipe of a low-temperature liquid cargo pump of an LNG (liquefied natural gas) ship pump tower, which structurally comprises a simulation pump for prefabricating the outlet pipe of the liquid cargo pump, a pump bracket used for mounting the simulation pump and matched with a plurality of bolts, and a pump base used for mounting the pump bracket, the outer side of the simulation pump is provided with a centering gasket used for adjusting the installation position of the simulation pump and a square gasket used for centering adjustment of the simulation pump. The invention further discloses the LNG ship pump tower low-temperature liquid cargo pump outlet pipe prefabricating method. The tool for prefabricating the outlet pipe of the low-temperature liquid cargo pump of the LNG ship pump tower has the advantages of being novel in design and easy to manufacture, in addition, the whole prefabricating process of the outlet pipe can be completed under a workshop transverse table in a prefabricating mode, on one hand, the construction difficulty during prefabricating of the tool can be effectively reduced, and on the other hand, the construction period is shortened; and on the other hand, workers do not need to get on the ship for a long time to enter the liquid cargo tank for construction and run back and forth during prefabrication operation.

    本发明涉及船舶建造技术领域,具体为一种LNG船泵塔低温液货泵出口管预制用工装,其结构分别包括液货泵出口管预制用的模拟泵、用于模拟泵安装且搭配有若干螺栓的泵支架和用于泵支架安装的泵底座,螺栓的周侧面搭配有螺母,模拟泵的外侧分别安装有用于模拟泵安装位置调节的调中垫片和用于模拟泵对中调节的方垫片;还包括一种LNG船泵塔低温液货泵出口管预制方法。本发明一种LNG船泵塔低温液货泵出口管预制用工装具有设计新颖,制作容易的优点,此外出口管的整个预制过程均能够在车间横台下预制完成,一方面能够有效降低本工装预制时的施工难度,另一方面在预制作业时工人无需长时间上船进入液货舱内施工,来回奔波。
