The invention relates to a ship liquid tank fixing system, which is characterized in that a liquid tank on a ship is arranged in a hydraulic tank box with a uniform size, the hydraulic tank box is a rectangular box body, and four corners of the rectangular box body are respectively and fixedly provided with a pressed part; a pair of fixing frames are arranged in a cabin, and a row of rectangular box bodies are placed between the pair of fixing frames; the hydraulic fixing mechanism comprises a base, a hydraulic cylinder and a claw arm; the base is fixed to the fixing frames, one end of the hydraulic cylinder is hinged to the base, the other end of the hydraulic cylinder is hinged to the rear end of the claw arm, the claw arm is bent, the bent portion is hinged to the fixing frames, a clawis arranged at the front end of the claw arm, and when the hydraulic cylinder contracts, the claw arm rotates and enables the claw to hook the pressed part. A hydraulic cylinder pressure compensationsystem is provided with a counterbalance valve and an energy accumulator, the counterbalance valve ensures that a hydraulic pump stops working after the liquid oxygen tank box is fixed, and the liquidoxygen tank box is still reliably fixed for a long time; the energy accumulator completes alternate work of active oil supplementing and passive energy accumulation and is used for reducing pressurefluctuation of a hydraulic system.
本发明涉及一种船舶液罐固定系统,船舶上的液罐置于统一大小的液压罐箱内,液压罐箱为矩形箱体,矩形箱体的四个角部位分别固定设有受压部件;船舱内设有一对固定架,一排矩形箱体置放在一对固定架之间;液压固定机构包括底座、液压缸、钩爪臂;底座固定在固定架上,液压缸一端与底座铰接,另一端与钩爪臂的后端铰接,钩爪臂呈弯折状,弯折部位与固定架铰接,钩爪臂的前端具有一钩爪,在液压缸收缩时,钩爪臂旋转并使钩爪钩住受压部件;液压缸压力补偿系统设有抗衡阀和蓄能器,抗衡阀保证液氧罐箱被固定好后液压泵停止工作,液氧罐箱仍被长时间的可靠固定;蓄能器完成主动补油与被动蓄能交替工作,用于减小液压系统压力波动。
