The invention discloses a lifting device used for installing a natural gas pipeline. The lifting device comprises a fixing mechanism, a winding mechanism, a supporting frame and a locking mechanism. The fixing mechanism and the supporting frame are connected in a sliding manner. The winding mechanism is arranged on the supporting frame, and the output end of the winding mechanism is connected withthe locking mechanism. A moving frame is connected to one end of the supporting frame in a rotating manner. According to the lifting device, the moving frame is utilized and can rotate at one end ofthe supporting frame, then the distance from the pipeline to a wall face can be adjusted, meanwhile, a steel wire rope is fixed through two first rotating wheels, and thus the situation that when a steel pipe is lifted, damage to the pipeline is caused due to separation of the steel wire rope is prevented. A lifting base, a locking plate and a rotating buckle are utilized for fixing pipelines withdifferent diameters, friction force between the pipeline and the locking mechanism can be increased by rubber friction pads bonded to the inner side of the lifting base and the inner side of the rotating buckle, and thus safety in the lifting process of the pipeline is improved.

    本发明公开了一种用于天然气管道安装的起吊装置,包括固定机构、卷扬机构、支撑架、锁紧机构,所述固定机构与所述支撑架滑动连接,所述卷扬机构设置在所述支撑架上且其输出端与所述锁紧机构连接,所述支撑架的一端转动连接有活动架。本发明利用活动架可以在支撑架的一端进行转动,继而可以调节管道距离墙面的距离,同时通过两个第一转轮来对钢丝绳进行固定,从而防止在起吊钢管时钢丝绳脱离造成管道的损坏;利用提升座、锁紧板和转动扣来对不同直径的管道进行固定,并通过粘接在提升座和转动扣内侧的橡胶摩擦垫来增大管道与锁紧机构的摩擦力,从而提高管道在吊装过程中的安全性。
