The invention provides a lifting appliance for lifting a reinforcement cage and a hoisting machine. M rows and n columns of lifting chain groups are arranged at the bottom of a truss, then multi-point lifting of the reinforcement cage on the same plane can be realized, each lifting chain group comprises k bearing chains with the lengths sequentially increased, and then multi-point lifting of the reinforcement cage on the same vertical line can be realized. A plurality of bearing rods are horizontally inserted into the reinforcement cage in a layered mode, lifting hooks are directly connected with the bearing rods, and the bearing rods make contact with all framework pieces and steel bars of the layer where the bearing rods are located. According to the lifting appliance for lifting the reinforcement cage and the hoisting machine, the lifting tension borne by the reinforcement cage is uniformly distributed at a plurality of point positions of a three-dimensional space of the reinforcement cage, so that the lifting tension borne by each point position is effectively reduced, then the problem of fracture possibly caused by large tension borne by the framework pieces or the steel bars is avoided, deformation of the reinforcement cage is also prevented, and meanwhile, the reinforcement cage can be kept balanced during lifting through multi-point lifting.
本发明提供的用于吊装钢筋笼的吊具和起重机械,在桁架底部设置m行、n列起重链组,可实现对钢筋笼同一平面进行多点起吊,每组起重链组包括k条长度依次增加的承载链条,可对钢筋笼在同一竖直线上实现多点起吊。多根承重杆分层水平插入钢筋笼内,吊钩直接与承重杆连接,承重杆与所在层的所有骨架片以及钢筋接触。本发明提供的用于吊装钢筋笼的吊具和起重机械,将钢筋笼所承受的起吊拉力均匀分布在钢筋笼立体空间的多个点位,有效降低了各点位所承受的起吊拉力,避免发生骨架片或钢筋承受较大的拉力可能造成的断裂问题,也防止钢筋笼变形,同时多点起吊也使钢筋笼在起吊时可保持平衡。
