The threaded rod 313 is close to the one end of locating hole 11 and is rotated and install locating plate 312, and the bottom of locating plate 312 and the surface contact of positioning disk 1 are equipped with mounting groove 3121 on the locating plate 312, rotate along the horizontal direction in the mounting groove 3121 and install registration roller 5. A hand wheel 314 is coaxially arranged at one end of the threaded rod 313 far away from the positioning hole 11.
In the embodiment of the present application, the hand wheel 314 rotates one turn to drive the positioning plate 312 to move 1cm toward the positioning hole 11, so that in an actual operation process, an operator can control the number of turns of the hand wheel 314, so that the three positioning assemblies 31 can move the same distance toward the positioning hole 11, and the purpose that the three positioning assemblies 31 push the reinforcement cage 4 to the center of the pile hole together is achieved.
Referring to fig. 2, in the actual construction process, if the elevation control of the reinforcement cage 4 is inaccurate, the floating and sinking amplitudes are too large, and the construction progress is affected by measures such as cutting and lengthening in the follow-up process. Therefore, an elevation setting mechanism 6 for controlling the elevation of the reinforcement cage 4 is provided on the positioning plate 1 at a position avoiding the positioning unit 31.
Specifically, the elevation setting mechanism 6 includes a height setting lever 61 and a pair of fixing members 62. The height fixing rod 61 is arranged along the radial direction of the positioning hole 11, the height fixing rod 61 is fixed on the positioning disk 1 by a pair of fixing components 62 after penetrating through the lifting rib 7 on the steel reinforcement cage 4, and the pair of fixing components 62 are arranged at two ends of the height fixing rod 61 in a one-to-one correspondence manner.
Referring to fig. 2, in particular, the fixing assembly 62 includes a pair of fixing posts 621 and a fixing pin 622, and the fixing posts 621 are welded on the surface of the positioning plate 1. In the embodiment of the present application, the pair of fixing posts 621 are two L-shaped posts with opposite openings, and an interval for placing the height-fixing rod 61 is formed between the pair of positioning posts by welding. The fixing pin 622 is located above the height fixing rod 61, and the fixing pin 622 passes through the pair of fixing posts 621 in sequence and then is overlapped on the height fixing rod 61, so that the movement of the height fixing rod 61 in the vertical direction is limited.
In the embodiment of the application, the fixed height rod 61 and the fixed assembly 62 are used in a matched manner, so that the top elevation and the bottom elevation of the reinforcement cage 4 in the concrete pouring and forming process are limited, the elevation of the reinforcement cage 4 is controlled, and the pile forming quality is improved.
The implementation principle of the positioning device for improving the positioning precision of the pile foundation reinforcement cage is as follows: in the process of hoisting the reinforcement cage 4, an operator can push the reinforcement cage 4 to adjust the position by adjusting the position of the positioning component 31 by using the principle that three points determine a circle, and the positioning component 31 jointly pushes the reinforcement cage 4 until the reinforcement cage 4 reaches the central position of the pile hole. In the process, the lifting appliance on the crane continuously moves along with the position change of the reinforcement cage 4, so that the reinforcement cage 4 is always kept in a vertical state. And then slowly lowering the reinforcement cage 4 until the reinforcement cage 4 is placed at the center of the pile hole. The reinforcement cage 4 which finishes the hoisting process by using the method is not easy to have deviation on the placement position, and the pile forming quality is effectively improved.
