[0030] The following will refer to the appendix. Figures 1 to 5 The present invention will be described in detail with reference to the embodiments.

[0031] Overall, this utility model proposes a drill rod positioning device for a bearing pile expansion forming machine, including a base ring 1, a top ring 2 rotatably connected to the top of the base ring 1, a mounting frame 301 fixedly mounted on the top surface of the top ring 2 by a vertical rod 3, and a positioning component mounted on the mounting frame 301.

[0032] like Figure 1 and Figure 2As shown, the positioning assembly includes clamping rods 4, sliding blocks 401, screws 5, and clamping plates 6. The clamping rods 4 are symmetrically arranged inside the mounting frame 301. The sliding blocks 401 are fixedly arranged at the ends of the clamping rods 4 and slidably connected to the inner side wall of the mounting frame 301. The two clamping rods 4 are fixedly provided with arc-shaped clamping plates 6 on opposite sides. The top ring 2 is also screwed with bolts 202 for limiting the position. The positioning assembly is also provided with a driving assembly that drives the two clamping rods 4 to move closer or further apart.

[0033] In this embodiment, the clamping rod 4 and clamping plate 6 in the positioning assembly can accurately position the drill rod. During the expansion construction of the support pile, ensuring that the drill rod is in the accurate position ensures that the hole position is accurate and effectively avoids pile position deviation caused by drill rod offset, thus guaranteeing the construction quality of the support pile and improving the stability and safety of the building.

[0034] The clamping rods 4 in the positioning assembly can move closer or further away under the action of the drive assembly. This design allows the device to adapt to drill rods of different diameters. When facing the construction needs of pile supports of different specifications, there is no need to replace the entire positioning device. Simply adjusting the spacing of the clamping rods 4 through the drive assembly can achieve the positioning of drill rods of different diameters, greatly improving the versatility and flexibility of the device and reducing construction costs.

[0035] In addition, the frame structure consisting of the chassis ring 1, top ring 2, and upright rod 3 provides stable support for the entire positioning device. During construction, it can withstand the vibration and impact forces generated when the drill rod is working, ensuring the stability of the positioning device and reducing construction interruptions and adjustment time caused by device shaking.

[0036] like Figure 4 As shown, a bolt 202 for limiting the rotation of the top ring 2 is screwed onto the top ring 2. The bolt 202 can limit the rotation of the top ring 2 to prevent inaccurate positioning or safety accidents caused by accidental rotation of the top ring 2 during construction.

[0037] In practice, the base ring 1 is placed stably in a suitable position on the pile expansion machine, ensuring a secure connection between the base ring 1 and the expansion machine. Since the top ring 2 is rotatably connected to the top of the base ring 1, it can rotate freely on the base ring 1, allowing for flexible adjustments based on the drill rod's position. Based on the initial position of the drill rod, rotate the top ring 2 until the mounting frame 301 is roughly aligned with the drill rod. Observe or measure to ensure the position of the mounting frame 301 meets the requirements for subsequent drill rod positioning. After adjusting the position of the top ring 2, tighten the limiting bolts 202 screwed onto the top ring 2 to fix it in its current position, preventing rotation during subsequent operations.

[0038] The drive assembly on the positioning component is activated, and it begins to operate, generating a driving force that acts on the clamping rods 4 on both sides, causing the sliding block 401 to slide on the inner wall of the mounting frame 301. Depending on the diameter of the drill rod, the drive assembly is controlled to move the clamping rods 4 closer or further apart, adjusting the spacing to ensure the clamping plates 6 accurately clamp the drill rod. The drive assembly is continued to move the clamping rods 4 closer together until the arc-shaped clamping plates 6 are tightly fitted against the outer wall of the drill rod, forming a stable clamping force. At this point, the drill rod is accurately positioned at the center of the mounting frame 301, preventing any horizontal movement or deflection.

[0039] After confirming that the drill rod has been securely positioned, operate the drive assembly to move the clamping rods 4 on both sides away from each other, releasing the clamp on the drill rod. Finally, start the pile expansion machine, and the drill rod begins to rotate and begin the expansion operation.

[0040] It should be noted that the curved openings of the clamping plates 6 on both sides face each other. This design allows the clamping plates 6 to better fit against the outer surface of the drill rod. Since the drill rod is typically cylindrical, this structure with opposing curved openings increases the contact area between the clamping plates 6 and the drill rod, forming a tighter enclosure. This provides comprehensive constraint on the drill rod in the horizontal direction, effectively reducing swaying and offset during positioning, improving the accuracy of drill rod positioning, providing a more precise benchmark for the expansion and shaping of the bearing pile, and ensuring construction quality.

[0041] like Figure 2 and Figure 3 As shown, the drive assembly includes a screw 5, a chain 701, and a sprocket 7. The screw 5 is symmetrically rotated within the mounting frame 301. The two ends of the screw 5 are provided with threads in opposite directions. The clamping rods 4 on both sides are threadedly connected to the two ends of the screw 5. The sprocket 7 is fixedly disposed on the outer circumference of the end of the screw 5 shown. The two sprockets 7 are connected by the chain 701.

[0042] A motor 8 is fixedly mounted on the outer wall of the mounting frame 301, and the output shaft of the motor 8 is fixedly connected to the screw 5 on one side.

[0043] In this embodiment, the screws 5 on both sides are connected by a chain 701 and a sprocket 7. When the motor 8 starts and drives one screw 5 to rotate, the other screw 5 will rotate synchronously in the opposite direction under the transmission action of the sprocket 7 and the chain 701. Since the two ends of the screws 5 on both sides have threads with opposite helical directions, and the clamping rods 4 on both sides are threaded to the two ends of the screws 5 respectively, the clamping rods 4 on both sides can move closer or further away from each other at the same speed. This synchronous drive method ensures that the drill rod is subjected to uniform force during the positioning process, and can quickly and accurately reach the predetermined position, which greatly improves the positioning efficiency and accuracy, reduces the positioning deviation caused by the asynchronous movement of the clamping rods 4 on both sides, and provides a reliable guarantee for the expansion and shaping construction of the support pile.

[0044] To further enhance the positioning effect and prevent shaking, in this embodiment, a clamping assembly is fixedly provided on the mounting frame 301. The clamping assembly includes vertical rods 9 symmetrically fixed on the top surface of the clamping rod 4, a slot 901 opened at the top of the vertical rod 9, and a movable plate 902 rotatably disposed at the end in the slot 901.

[0045] The two movable plates 902 are inclined downwards towards the side that is close to each other. A spring 904 is provided between the movable plate 902 and the vertical rod 9. One end of the spring 904 is fixedly connected to the vertical rod 9, and the other end is fixedly connected to the movable plate 902.

[0046] The two movable plates 902 extend downwards at an angle towards each other, giving the clamping assembly an adaptive capability. When the drill rod enters the positioning device, regardless of its diameter, the movable plates 902 automatically adjust their angle and position under the action of the spring 904, ensuring a tight fit with the drill rod surface. As the clamping rod 4 moves, the movable plates 902 gradually increase the pressure on the drill rod, achieving stable and reliable clamping. This ensures that the drill rod will not shake or shift during construction, improving construction accuracy and safety.

[0047] Furthermore, the symmetrically arranged vertical rods 9 and movable plates 902 ensure that the clamping force is evenly distributed around the drill rod. During clamping, the movable plates 902 on both sides simultaneously apply pressure to the drill rod, avoiding damage caused by uneven clamping force, such as drill rod skewing or excessive local stress. This uniform force application helps maintain the straightness and stability of the drill rod, extending its service life.

[0048] Based on the above configuration, multiple rubber extrusion posts 903 are uniformly fixed on opposite sides of the two movable plates 902. These extrusion posts 903 are evenly distributed on opposite sides of the movable plates 902. When in contact with the drill rod, the extrusion posts 903 can embed into the tiny unevenness of the drill rod surface, increasing the contact area and friction between the movable plates 902 and the drill rod.

[0049] In addition, such as Figure 5 As shown, a scale 102 is fixedly installed on the base ring 1, allowing the operator to directly read the rotation angle of the base ring 1. During the expansion and shaping construction of the support pile, different construction requirements may require the drill rod to be used for hole enlargement at a specific angle. Using the scale 102, the operator can accurately rotate the base ring 1 to the required angle without the need for additional measuring tools, greatly improving the accuracy and efficiency of angle positioning.

[0050] As a preferred structure in this embodiment, such as Figure 4 As shown, the top ring 2 is rotatably connected to the chassis ring 1 through a rotating assembly. The rotating assembly includes an inner groove 101 formed on the top surface of the chassis ring 1 and conforming to its contour, and a rotating block 201 that cooperates with the inner groove 101. The rotating block 201 is fixedly disposed on the bottom surface of the top ring 2.

[0051] In this embodiment, the engagement between the inner groove 101 and the rotating block 201 provides excellent guidance and support for the rotation of the top ring 2 relative to the chassis ring 1. The rotating block 201 can slide smoothly within the inner groove 101, reducing friction and resistance during rotation, allowing the top ring 2 to easily rotate around the central axis of the chassis ring 1. Operators can quickly and accurately adjust the angle of the top ring 2 according to construction needs, improving construction efficiency and operational convenience.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
