Butt-joint stabilizing device for lowering reinforcement cage

The utility model discloses a steel reinforcement cage lowering butt joint stabilizing device which comprises a stabilizing base, an orifice sleeve (4) and a pulling assembly. The middle of the stable base is hollowed out to form an annular structure, the stable base is placed on the ground, and the hollowed-out middle of the stable base is aligned with an orifice of a pile hole. The orifice sleeve (4) is of a cylindrical structure and is connected to the hollow bottom of the middle part of the stable base, so that the orifice sleeve (4) can be coaxially inserted into a pile hole; the multiple sets of pulling assemblies are arranged on the stable base at intervals and arranged above the orifice sleeve (4) in the circumferential direction, and the upper portion of a reinforcement cage (10) is detachably connected with the stable base through the multiple sets of pulling assemblies, so that the lower portion of the reinforcement cage (10) penetrates through the stable base and the orifice sleeve (4) and is coax
