[0027] As Figures 1 to 5As shown, specifically, the moving plate 3 is provided with a circular plate portion 14, the bracket 2 is provided in a square shape, and the center of the circular plate portion 14 is concentric with the midpoint of the bracket 2. When the reinforcement cage is operated from below, the base 1 is placed at the hole pile, so that the circular plate portion 14 is located at the top end of the hole pile opening. The bracket 2 is fixedly provided with a guide seat 6, the guide seat 6 is provided with a guide groove 7, and the moving seat 8 is slidably connected in the guide groove 7. The moving seat 8 is provided with a limiting groove 9, and the moving plate 3 is slidably connected in the limiting groove 9. The moving plate 3 is fixedly provided with a motor 10 for driving the moving plate 3 to move. The output shaft of the motor 10 is fixedly connected with a threaded rod 11, and the threaded rod 11 is used for threaded connection of the moving plate 3. The motor 10 is started to drive the threaded rod 11 to rotate, so that the moving plate 3 moves downward in the limiting groove 9. The movement of the moving plate 3 causes the connecting plate 5 at the bottom end to open and move. The arc plate 4 is fixedly connected with an electromagnet seat 12 for facilitating connection and disconnection of the arc plate 4 and the connecting plate 5. The electromagnet seat 12 is provided with a containing groove, and the containing groove is provided with a matched magnetic attraction seat 13. The connecting plate 5 is rotatably connected between the magnetic attraction seat 13 and the moving plate 3. Therefore, the opening and movement of the connecting plate 5 can drive the arc plate 4 to move close to the edge of the bracket 2 through the magnetic attraction seat 13 and the electromagnet seat 12. At this time, the electromagnet seat 12 is in an energized state, so that the magnetic attraction seat 13 is attracted in the containing groove in the electromagnet seat 12. The limiting assembly includes a bent plate 15 provided at the top end of the bracket 2 for limiting the arc plate 4. Two guide rods 16 are fixedly connected between the bent plate 15 and the arc plate 4, and the guide rods 16 are slidably connected with the bracket 2. The bent plate 15 is threadedly connected with a screw rod 17 for limiting the movement distance of the bent plate 15. At this time, the movement of the arc plate 4 causes the guide rods 16 to slide on the bracket 2, and the guide rods 16 can keep the stability of the arc plate 4 during movement. During the movement of the arc plate 4, the moving system is started to move the bracket 2 in the base 1, so that the bracket 2 can drive the arc plate 4 to move. At this time, through the cooperation of the opening and movement of the arc plate 4 driven by the connecting plate 5 and the overall movement of the arc plate 4 driven by the bracket 2, the four arc plates 4 are all attached to the inner wall of the hole pile. When the four arc plates 4 are all attached to the inner wall of the hole pile, the circle formed by the arc plates 4 has the same center as the hole pile.
[0028] As Figures 1 to 5As shown, in particular, the electromagnet base 12 is provided with a laser pointer 20 for measuring the radius of the circle formed by the arc plates 4, and the support 2 is provided with a scale 21 for measuring the radius in cooperation with the laser pointer 20. After the circle formed by the arc plates 4 is determined to have the same center as the hole pile, the motor 10 is reversely driven to move the moving plate 3 upward, so that the connecting plate 5 drives the arc plates 4 to move reversely. At this time, the radius of the circle formed by the arc plates 4 is determined according to the laser line emitted by the laser pointer 20 on the electromagnet base 12, and the laser line emitted by the laser pointer 20 is incident on the scale 21, so that the size of the radius can be known. The position of the arc plates 4 is adjusted according to the radius of the reinforcement cage, so that the arc plates 4 are located at the position where the radius of the circle formed is the same as the radius of the reinforcement cage. Then, the motor 10 is stopped, the screw rod 17 is rotated to move on the bending plate 15, and the end of the screw rod 17 is attached to the support 2. After the attachment, the guide rod 16 and the arc plates 4 are limited from moving to the edge of the support 2 by limiting the bending plate 15 from moving to the edge of the support 2. The electromagnet base 12 is de-energized, and then the motor 10 is started again to drive the connecting plate 5 to separate the magnetic seat 13 from the electromagnet base 12. At this time, the arc plates 4 remain stationary. The moving seat 8 is fixedly connected with a connecting frame 18, and the support 2 is fixedly installed with a hydraulic cylinder 19 for pushing the moving seat 8 to slide in the guide groove 7. The hydraulic cylinder 19 is fixedly connected with the connecting frame 18. The hydraulic cylinder 19 is started and pushes the moving seat 8 to move in the guide groove 7 through the connecting frame 18. The movement of the moving seat 8 drives the moving plate 3 and the connecting plate 5 and other components to move, so that they move to one side of the support 2, so that they are located at a position not affecting the reinforcement cage below. After the components are moved to one side, the reinforcement cage can be gradually lowered into the hole pile by the crane. During the lowering process, when the position of the reinforcement cage deviates, the bottom end position gradually approaches the arc plates 4. At this time, the bottom end position of the reinforcement cage is gradually adjusted under the limiting action of the arc plates 4, and the accuracy of the lowering position of the reinforcement cage is maintained under the limiting action of the circle formed. The arc plates 4 cannot move to the edge of the support 2 under the limiting action of the screw rod 17, and the circle formed by the arc plates 4 is concentric with the center of the hole pile, so that the arc plates 4 limit the position of the reinforcement cage after lowering to be concentric with the hole pile. After the lowering is completed, the moving seat 8 is reset by reversely driving the hydraulic cylinder 19, and then the motor 10 is driven to move through the connecting plate 5 and the moving plate 3, so that the magnetic seat 13 enters the electromagnet base 12 during the position adjustment, so as to perform the subsequent reinforcement cage lowering operation again.
