Multifunctional mounting device for pile foundation reinforcement cage

The utility model relates to the technical field of building construction, and discloses a pile foundation reinforcement cage multifunctional mounting device which comprises a supporting frame, a driving mechanism and a plurality of moving rods, the supporting frame is arranged on a steel casing, the moving rods are slidably connected to the supporting frame, the driving mechanism is arranged on the supporting frame, and the driving mechanism is arranged on the supporting frame. The multiple moving rods are all connected with the driving mechanism, and the driving mechanism is used for driving the multiple moving rods to move so that the multiple moving rods can support a reinforcement cage. The device has the advantages that the labor intensity of constructors for continuously pulling and inserting steel pipes for supporting the reinforcement cage is reduced, the workload of the constructors is reduced, and the lowering quality and speed of the reinforcement cage are remarkably improved. 本申请涉及建筑施工技术的领域，公开了一种
