The invention discloses a stable lifting device for anti-falling anti-corrosion pipeline construction, and relates to the technical field of lifting devices. Comprising a crane, a hanging bracket is arranged on the crane, a connecting piece is connected in the hanging bracket in a limited, sealed and sliding mode, a hanging rope of the crane penetrates through the hanging bracket and is fixedly connected with the connecting piece, and the connecting piece is fixedly connected with pull ropes which are symmetrically distributed and penetrate through the hanging bracket. The end, away from the connecting piece, of the pull rope is fixedly connected with a pull rod in limiting sliding connection with the hanging bracket, the hanging bracket is in limiting sliding connection with symmetrically-distributed sliding frames, and L-shaped frames are in limiting sliding connection in the sliding frames. The L-shaped frame penetrates into the anti-corrosion pipeline to fix the anti-corrosion pipeline, the step of tilting the pipeline is omitted, meanwhile, point contact of the L-shaped frame relative to the contact face of the inner wall of the pipeline is changed into face contact, the stress area of the pipeline is increased, and the probability that an anti-corrosion coating on the anti-corrosion pipeline is damaged is reduced.
本发明公开了涉及提升装置技术领域的一种防坠式防腐管道施工用稳定提升装置。包括有吊车,所述吊车上设置有吊架,所述吊架内限位且密封滑动连接有连接件,所述吊车的吊绳穿过所述吊架并与所述连接件固接,所述连接件固接有对称分布的且均穿过所述吊架的拉绳,所述拉绳远离所述连接件的一端固接有与所述吊架限位滑动连接的拉杆,所述吊架限位滑动连接有对称分布的滑动框,所述滑动框内限位滑动连接有L形架。本发明通过L形架深入防腐管道内将其固定,免除了将管道翘起的步骤,同时L形架相对于吊钩对管道内壁接触面由点接触改变为面接触,增大了管道的受力面积,降低了防腐管道上防腐涂层受到损伤的概率。
