The invention discloses a casing uncovering tool and method for a low-pressure compressor. The casing uncovering tool comprises a door-shaped supporting mechanism. The door-shaped supporting mechanism is installed above the low-pressure compressor, and the lifting executing mechanism is arranged on the door-shaped supporting mechanism. Wherein the hoisting executing mechanism comprises a hydraulic cylinder body and a telescopic rod, and the hydraulic cylinder body is installed on the door-shaped supporting mechanism; the upper end of the telescopic rod is connected with the hydraulic cylinder body, and the lower end of the telescopic rod vertically extends downwards and is connected with the lifting appliance mechanism; the lifting appliance mechanism is horizontally arranged, one end of the lower portion of the lifting appliance mechanism is used for being connected with one end of an upper half casing of the low-pressure compressor, and the other end of the lower portion of the lifting appliance mechanism is used for being connected with the other end of the upper half casing of the low-pressure compressor. The telescopic rod driven by the hydraulic cylinder body is adopted for rigid lifting uncovering, abnormal bounce caused by flexible lifting is avoided, and then mutual collision of the blades is avoided; and the hoisting process can be stopped at any time, so that the pin is prevented from falling off, and other harms and damages caused by falling off are avoided.

    本发明公开了一种用于低压压气机的机匣开盖工装及方法,包括门型支撑机构;门型支撑机构安装在低压压气机的上方,起吊执行机构设置在门型支撑架上;其中,起吊执行机构包括液压缸体及伸缩杆,液压缸体安装在门型支撑机构上;伸缩杆的上端与液压缸体相连,伸缩杆的下端竖直向下延伸,并与吊具机构相连;吊具机构水平设置,吊具机构的下方一端用于与低压压气机的上半部机匣一端相连,吊具机构的下方另一端用于与低压压气机的上半部机匣另一端相连;本发明采用液压缸体驱动的伸缩杆进行刚性起吊开盖,避免了柔性起吊造成的异常弹跳,进而避免叶片的相互碰撞;且起吊过程能够确保随时停止,避免销钉的脱出、脱落造成的其他危害和损伤。
