[0018] This disclosure provides an auxiliary positioning device for pile foundation construction, comprising a first annular plate, a first cylinder, a second cylinder, a ball screw, a screw nut, a first support plate, an optical shaft, a second support plate, and rollers. The first cylinder is connected to the first annular plate and supports the rotatable ball screw and slidable optical shaft. The second cylinder is connected to the second annular plate and sleeved outside the first cylinder, supporting the rotatable ball screw. The second cylinder, first cylinder, and first annular plate are aligned along a centerline so that the precast pile can be simultaneously positioned at the center of the second cylinder, first cylinder, and first annular plate. The ball screw is rotatably mounted on the first and second cylinders along the radial direction of the first annular plate and is evenly distributed around the center of the first annular plate, allowing rotational movement relative to both cylinders. Screw nuts are installed on each ball screw and located between the first and second cylinders, converting rotational motion into linear motion. The first support plate is installed on each screw nut and drives the optical shaft to move. The optical axis slides radially through the first cylinder along the first annular plate and is connected to each of the first support plates, serving as a guide and support.

[0019] During operation, multiple ball screws rotate synchronously under external force. Guided by multiple optical axes, these screws, supported by brackets, move multiple first support plates radially along the first annular plate. Then, supported by the multiple optical axes, multiple second support plates move radially along the first annular plate. This ultimately moves multiple rollers radially along the first annular plate, allowing them to move closer together or separate. This enables them to abut against the annular sides of precast piles of different diameters, facilitating the positioning of precast piles of varying diameters and expanding their applicability.

The second cylinder 3, the first cylinder 2, and the first annular plate 1 are arranged along the same center line. The ball screw 4 is rotatably mounted on the first cylinder 2 and the second cylinder 3 along the radial direction of the first annular plate 1, and is evenly distributed around the center of the first annular plate 1. The screw nut 5 is installed on each ball screw 4, and is located between the first cylinder 2 and the second cylinder 3. The first support plate 6 is installed on each screw nut 5. The shaft 7 is slidably inserted through the first cylinder 2 along the radial direction of the first annular plate 1, and is connected to each first support plate 6.

Rollers 9 are installed on each second support plate 8 and are used to abut against the annular side of the precast pile. Multiple ball screws 4 can be rotated in a controlled manner to bring the multiple rollers 9 closer together or separate them.

[0037] This disclosure provides an auxiliary positioning device for pile foundation construction, comprising a first annular plate 1, a first cylinder 2, a second cylinder 3, a ball screw 4, a screw nut 5, a first support plate 6, a shaft 7, a second support plate 8, and rollers 9. The first cylinder 2 is connected to the first annular plate 1 and supports the rotatable ball screw 4 and the slidable shaft 7. The second cylinder 3 is connected to the second annular plate 10 and sleeved on the outside of the first cylinder 2, supporting the rotatable ball screw 4. The second cylinder 3, the first cylinder 2, and the first annular plate 1 are arranged along the same centerline so that the precast pile can be simultaneously positioned at the center of the second cylinder 3, the first cylinder 2, and the first annular plate 1. The ball screw 4 is rotatably mounted on the first cylinder 2 and the second cylinder 3 along the radial direction of the first annular plate 1, and is evenly distributed around the center of the first annular plate 1, allowing rotational movement relative to both the first cylinder 2 and the second cylinder 3. Nuts 5 are installed on each ball screw 4, located between the first cylinder 2 and the second cylinder 3, and are used to convert rotational motion into linear motion. First support plates 6 are installed on each nut 5, and are used to move the optical shaft 7. The optical shaft 7 slides through the first cylinder 2 along the radial direction of the first annular plate 1, and is connected to each first support plate 6, serving as a guide and support. Second support plates 8 are connected to each optical shaft 7, located inside the first cylinder 2, and are used to support and install rollers 9. Rollers 9 are installed on each second support plate 8, and are used to abut against the annular side of the precast pile to jointly limit the precast pile's movement. Multiple ball screws 4 can be rotated in a controlled manner to bring the multiple rollers 9 closer together or separate them.

[0038] During use, multiple ball screws 4 rotate synchronously under the drive of external force. Then, guided by multiple optical shafts 7, the screw supports 21 drive multiple first support plates 6 to move radially along the first annular plate 1. Subsequently, supported by the multiple optical shafts 7, multiple second support plates 8 move radially along the first annular plate 1. Finally, this drives multiple rollers 9 to move radially along the first annular plate 1, allowing the rollers 9 to approach or separate. This enables them to abut against the annular sides of precast piles of different diameters, facilitating the positioning of precast piles of varying diameters and improving their applicability.

[0039] Optionally, combined Figure 1 and Figure 2 As shown, it also includes a second annular plate 10 and a first bevel gear 11. The second annular plate 10 is sleeved on the outside of the second cylinder 3 and rotatably mounted on the first annular plate 1. The second annular plate 10 includes bevel teeth located on its edge. The first bevel gear 11 is respectively mounted on each ball screw 4, and is located on the outside of the second cylinder 3, and meshes with the bevel teeth.

[0040] In this embodiment, a second annular plate 10 and a first bevel gear 11 are also included. The second annular plate 10 is sleeved on the outside of the second cylinder 3 and rotatably mounted on the first annular plate 1, enabling it to rotate relative to the first cylinder. The first bevel gears 11 are respectively mounted on each ball screw 4 and are located outside the second cylinder 3, respectively driving the multiple ball screws 4 to rotate. The multiple bevel gears mesh with the bevel teeth on the edge of the second annular plate 10, jointly transmitting driving force and changing the direction of the force. During use, when the second annular plate 10 rotates under the drive of an external force, the meshing of the teeth drives the multiple first bevel gears 11 to rotate simultaneously. This, in turn, drives the multiple ball screws 4 to rotate synchronously, ultimately causing the multiple rollers 9 to move closer together or separate.

[0041] Optionally, combined Figure 1 and Figure 3 As shown, it also includes a rotating shaft 12 and a second bevel gear 13. The rotating shaft 12 is rotatably mounted on the second cylinder 3 along the radial direction of the first annular plate 1.

The rotating shaft 12 is rotatably mounted on the second cylinder 3 along the radial direction of the first annular plate 1, and can rotate relative to the second cylinder 3. The second bevel gear 13 is mounted on the rotating shaft 12 and located outside the second cylinder 3, and rotates under the drive of the rotating shaft 12. The second bevel gear 13 meshes with bevel teeth to transmit driving force and change the direction of force. During use, under the drive of external force, the rotating shaft 12 rotates, which in turn drives the second bevel gear 13 to rotate. Through the meshing of the teeth, the second annular plate 10 rotates, ultimately causing the multiple rollers 9 to move closer together or separate.
