The utility model relates to an angle adjusting device for LNG unloading arm, which comprises an inner arm, an outer arm, a first runner, a wire rope, a hydraulic cylinder, a counterweight block, a pillar, a supporting workpiece and a hand hoist; the inner arm is vertically arranged on the pillar, the first runner is rotated at one end of the inner arm away from the pillar, the outer arm is connected at one end of the inner arm away from the pillar, and the outer arm is inclined to the inner arm to support the workpiece. One end is connected with the outer arm, the other end is connected with the inner arm; the wire rope is arranged around the first runner, and one end of the wire rope is connected with the hydraulic cylinder; the other end of the wire rope is connected with the counterweight block; the counterweight block is rotated on the inner arm; one end of the hand hoist is connected with the inner arm; the other end is connected with the counterweight block. By supporting the workpiece to support the outer arm and the inner arm, the angle between the outer arm and the inner arm is fixed, and the counterweight block is tracted and fixed by hand hoist, so that the angle between the inner arm and the outer arm and the angle between the inner arm of the counterweight block are fixed, so that the unloading arm can be more stable in the storage state, and the precision of the unloading arm can be guaranteed.

LNG卸料臂角度调整装置
本技术涉及液化天然气LNG卸料臂
,特别是涉及LNG卸料臂角度调整装置。
技术介绍
卸料臂是LNG(LiquefiedNaturalGas,液化天然气)接收站和接卸LNG船的重要设备之一。一般情况下LNG接收站配置3台卸料臂与1台气相返回臂,卸料臂处于码头平台前部,在使用及存放过程中受风浪影响较大,钢丝绳产生松弛,导致存放状态下卸料臂内臂和外臂之间夹角和配重块、内臂之间的夹角不一致。若不及时处理,会影响卸料臂操作精度,且影响液压缸密封性,导致液压缸的使用寿命降低;若长期如此更会造成卸料臂地基不均匀沉降,影响接收站的正常生产。
技术实现思路
基于此,有必要提供一种LNG卸料臂角度调整装置。一种LNG卸料臂角度调整装置,包括:内臂、外臂、第一转轮、钢丝绳、液压缸、配重块、立柱、支撑工件和手拉葫芦;所述内臂竖直设置于所述立柱上,所述第一转轮转动设置于所述内臂远离所述立柱的一端,所述外臂连接于所述内臂远离所述立柱的一端,所述外臂倾斜于所述内臂设置,所述支撑工件一端与所述外臂连接,另一端与所述内臂连接;所述钢丝绳绕所述第一转轮设置,且所述钢丝绳一端与所述液压缸连接,所述钢丝绳的另一端与所述配重块连接,所述配重块转动设置于所述内臂上,所述手拉葫芦一端与所述内臂连接,另一端与所述配重块连接。进一步地,所述内臂远离所述第一转动的位置设置有第二转轮,所述第二转轮转动设置于所述内臂上,所述配重块与所述第二转轮连接。进一步地,所述配重块的长度大于所述第二转轮的半径。进一步地,所述液压缸为油缸。进一步地,所述支撑工件一端设置有固定板,另一端设置有支撑板和夹 ...
