After rotating a certain angle, the electric wrench clamp is controlled to loosen, and then the second inner rotating ring is controlled to rotate in the opposite direction to reset, and then clamp again, and tighten again, and repeat this process to automatically tighten all the sleeves. During the tightening process, the second inner rotating ring repeatedly expands and contracts to ensure the stability of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0065] like Figure 1 to Figure 15 As shown, this embodiment proposes a centering and positioning structure for preventing the deflection of the pile foundation reinforcement cage, including a supporting vertical frame 1,

[0066] Also includes a centering mechanism, the centering mechanism includes,

[0067] The installation frame 2 is in the shape of a square. The installation frame 2 is installed between the supporting vertical frames 1. There are several installation frames 2, and several installation frames 2 are connected up and down. The size of the several installation frames 2 gradually decreases from top to bottom.

[0068] The alignment guide rollers 3 are four alignment guide rollers 3 installed on the four inner walls of each installation frame 2. Every four alignment guide rollers 3 are also arranged in a square. The square formed by the four alignment guide rollers 3 in the lowest installation frame 2 is the circumscribed square of the alignment guide rollers 3.

[0069] The inner spaces of the several layers of the upright guide rollers 3 from top to bottom form an inverted pyramid shape.

[0070] In this embodiment, during the pile foundation construction process, it is necessary to lower the steel cage at the pile foundation position. Before lowering, the centering and positioning structure used to prevent the pile foundation steel cage from deviating is assembled to the periphery of the pile foundation. During the lowering process, the crane lifts the steel cage, and then starts to descend at the position of the pile foundation. During the descent, the steel cage will continue to shake slightly until the bottom of the steel cage contacts the positive guide rollers 3 inside the installation frame 2, and then the lower part of the steel cage is stabilized. As the steel cage continues to descend, the steel cage enters the four positive guide rollers. During this process, the crane also adjusts its position so that the steel cage is always in a vertical state. Then, as the steel cage continues to descend, the bottom of the steel cage enters between the smaller positioning guide rollers 3, that is, the steel cage is gradually adjusted to the center position, and the crane is also adjusted accordingly until the steel cage extends out from between the lowest positioning guide rollers 3. At this time, the steel cage is in a vertical positioning state, that is, the centering and positioning of the steel cage are completed, eliminating the need for repeated manual adjustments during the lowering of the steel cage, thereby improving the efficiency of lowering the steel cage.

[0071] It also includes an adjustment and positioning mechanism, two of which are provided, and the two adjustment and positioning mechanisms are installed between the supporting vertical frames 1 in the up and down directions. The adjustment and positioning mechanism includes a first annular slide rail 4, a first inner rotating ring 5 and a correction rod 6. The first annular slide rail 4 is installed between the supporting vertical frames 1, and the first inner rotating ring 5 is rotatably set in the first annular slide rail 4. There are a plurality of correction rods 6, and the plurality of correction rods 6 are equidistantly installed on the inner ring surface of the first inner rotating ring 5 in an annular array.

[0072] The upper and lower centers of the two adjusting and positioning mechanisms are directly opposite to each other, and there is an angle difference between the adjusting and positioning rod 6 in the upper adjusting and positioning mechanism and the adjusting and positioning rod 6 in the lower adjusting and positioning mechanism.

[0073] During the process of the steel cage continuing to descend after completing the alignment between the alignment guide rollers 3, since the bottom end of the steel bars on the steel cage has a connecting sleeve, it is necessary to align the sleeve at the bottom end of each steel bar with the top end of the steel bar below, and manual angle adjustment is required to insert the sleeve directly into the top end of the steel bar below.

[0074] In this embodiment, after the steel cage is aligned between the alignment guide rollers 3 and continues to descend, the bottom end of the steel bar is inserted between the upper and lower alignment rods 6. Since there is an angle difference between the upper and lower alignment rods 6, each steel bar is located between the two upper and lower alignment rods 6. At this time, the upper first inner rotating ring 5 and the lower first inner rotating ring 5 are controlled to rotate in opposite directions, thereby driving the upper alignment rod 6 and the lower alignment rod 6 to rotate in opposite directions. Then, the upper and lower two alignment rods 6 will clamp the steel bars therebetween from both sides, thereby realizing the positioning of the steel bars, that is, each steel bar is positioned between the two alignment rods 6. Subsequently, the two first inner rotating rings 5 ​​are controlled to rotate in the same direction to fine-tune the angle so that the sleeve at the bottom end of the steel cage is aligned with the top of the steel bar below.

[0075] A plurality of vibration modules 7 are disposed on the outer ring surface of each of the first annular slide rails 4 .

[0076] Due to slight deviations in some steel bars, the bottom sleeve of some steel bars cannot be smoothly inserted. At this time, the vibration module 7 drives the first inner rotating ring 5 and the steel cage to vibrate slightly, so that the sleeve can be vibrated a small distance and smoothly inserted.

[0077] It also includes a tightening mechanism, the tightening mechanism includes,

[0078] The second annular slide rail 8 is installed between the supporting vertical frames 1, and the second annular slide rail 8 is located below the two adjustment and positioning mechanisms.

[0082] An electric wrench clamp 12 is connected to the telescopic end of each elastic telescopic rod 11 .

[0083] After the sleeve at the bottom end of the steel cage is successfully inserted into the top of the steel bar below, the sleeve moves into the opened electric wrench clamp 12, and then all the electric wrench clamps 12 are controlled to clamp the corresponding sleeves, and the second inner rotating ring 9 is controlled to rotate in the direction of tightening the sleeve, and then the second inner rotating ring 9 drives the electric wrench clamp 12 to rotate through the torsion spring rotating shaft seat 10 and the elastic telescopic rod 11, and then the electric wrench clamp 12 rotates and tightens the clamped sleeve. After rotating a certain angle, the electric wrench clamp 12 is controlled to loosen, and then the second inner rotating ring 9 is controlled to rotate in the opposite direction to reset, and then clamp again, and tighten again, and repeat this process to automatically tighten all the sleeves. During the tightening process, the second inner rotating ring 9 repeatedly expands and contracts to ensure the stability of the structure.
