The invention belongs to the technical field of hoisting devices, and particularly relates to a safe hoisting device for steel structure engineering construction. Comprising a supporting hanging plate, symmetrical first connecting seats are hinged to the supporting hanging plate, first telescopic rods are fixedly connected to the first connecting seats, second connecting seats are fixedly connected to the telescopic ends of the first telescopic rods, fixed rods are hinged to the second connecting seats, hanging hooks are hinged to the fixed rods, symmetrical connecting ropes are fixedly connected to a sliding frame, and the sliding frame is fixedly connected with a sliding rod. The symmetrical connecting ropes are jointly and fixedly connected with a square plate, the square plate is slidably connected with four L-shaped connecting plates, and the L-shaped connecting plates located on the same side of the I-shaped steel are jointly and fixedly connected with a supporting plate. The lifting hooks are matched with the lifting lugs, meanwhile, the supporting plates are used for providing part of upward supporting force for the I-shaped steel, the pulling force borne by the welding positions between the lifting lugs and the I-shaped steel is reduced, and the safety of the I-shaped steel in the lifting process is further improved.
本发明属于起吊装置技术领域,具体提及了一种用于钢结构工程施工用的安全型起吊装置。包括有支撑吊板,所述支撑吊板铰接有对称的第一连接座,所述第一连接座固接有第一伸缩杆,所述第一伸缩杆的伸缩端固接有第二连接座,所述第二连接座铰接有固定杆,所述固定杆铰接有吊钩,所述滑动架固接有对称的连接绳,对称的所述连接绳共同固接有方形板,所述方形板滑动连接有四个L连接板,位于工字钢同一侧的所述L连接板共同固接有支撑板。本发明通过吊钩与吊耳配合,同时利用支撑板为工字钢提供部分向上的支撑力,降低了吊耳与工字钢之间焊接处的所受到的拉力,进一步提高了工字钢在吊运过程中的安全性。
