The invention relates to a lifting appliance for lifting a large cable reel, and belongs to the technical field of cable reel lifting appliances. The lifting device comprises a lifting frame and a lifting arm mechanism installed on the lifting frame, the lifting arm mechanism comprises two lifting arm combinations which are symmetrically arranged front and back, and each lifting arm combination comprises two lifting arm assemblies which are symmetrically arranged left and right; the lifting arm assembly comprises a lifting arm and a supporting leg connected to the bottom end of the lifting arm, the supporting leg is located on the side, facing the lifting arm combination center, of the lifting arm, a first inclined supporting piece and an extrusion piece are arranged on the supporting leg, and the first inclined supporting piece is elastically installed on the supporting leg in a sliding mode in the direction inclining towards the lifting arm combination center from bottom to top; the first inclined supporting piece is used for being elastically pressed on the circumferential side wall of the circular side plate in the cable reel so as to support the cable reel along with the mutual approaching of the two sets of suspension arm assemblies which are symmetrical left and right. The cable reel can be supported more firmly, shaking between the cable reel and the lifting appliance in the cable reel transferring process is avoided, and the safety coefficient is higher.
本发明涉及一种吊装大型电缆盘的吊具,属于电缆盘吊具技术领域。本发明包括吊架以及安装在吊架上的吊臂机构,吊臂机构包括前后对称布置的两组吊臂组合,吊臂组合包括左右对称布置的两组吊臂组件;吊臂组件包括吊臂和连接在吊臂底端的支脚,支脚位于吊臂的朝向吊臂组合中心的一侧,支脚上设有斜撑件一和挤压件,斜撑件一沿着自下向上朝向吊臂组合中心倾斜的方向弹性滑动安装在支脚上;斜撑件一用于随着两组左右对称的吊臂组件的相互靠近而弹性压紧在电缆盘中圆形侧板的周向侧壁上以承托电缆盘。本发明能够对电缆盘进行更加牢固的支撑,避免转运电缆盘的过程中电缆盘与吊具之间发生晃动,安全系数更高。
