3) The conical barrel (44) with the corresponding diameter is clamped inside the clamping barrel (43), then the limiting rod (36) moves upwards to enable the clamping cone (8) to leave the clamping rack (9), the side vertical plate (22) is moved, the two adjusting screw rods (18) are rotated to enable the center of the conical barrel (44) to be aligned with the center of the pile hole, after the alignment, the limiting rod (36) naturally falls down, and meanwhile the locking rod (37) is used for blocking the top of the limiting rod (36) to be locked.
4) The spliced reinforcement holes are vertically hoisted by utilizing a crane, the bottom of a reinforcement cage is placed in a conical barrel (44), then the position of a clamping wheel (39) is adjusted by rotating a middle crank (6), the reinforcement cage is controlled to be clamped under the measurement of scales on the ruler rods (5), and meanwhile, the extending amount of the four ruler rods (5) is ensured to be equal.
5) The steel reinforcement cage is slowly placed by using a crane, the top lifting ring (1) is pressed downwards to compress the ejection spring (2), the bottom of the conical cylinder (44) is butted with the top of the pile hole, and the locking rack (23) is inserted into the locking hole (31) to prevent the position of the conical cylinder (44) from moving upwards, so that the steel reinforcement cage smoothly enters the pile hole.
6) The middle part of the reinforcement cage is fixed by the conical barrel (44) and the clamping wheel (39), and meanwhile, the top of the reinforcement cage is pulled by a hoisting cable rope, so that the reinforcement cage is prevented from scratching the inner wall of the pile hole when falling.
