Description

Technical Field

[0001] This utility model belongs to the field of pipe pile technology, and in particular relates to a positioning device for triangular piles. Background Technology

[0002] Triangular piles are a type of foundation engineering material with a special triangular cross-section. Due to their unique shape, the triangular cross-section allows for more even stress distribution within the soil, enhancing structural stability. Their shape also facilitates precise positioning and insertion into the ground, making them suitable for various geological conditions. However, because the positioning devices in related technologies are designed for circular or square pipe piles, they are not well-suited for triangular cross-sections, leading to issues with positioning accuracy. Furthermore, the lack of specialized equipment necessitates additional operations or procedures for construction workers to adjust the pile position, further increasing the complexity of the work. Summary of the Invention

[0003] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A positioning device for triangular stakes includes a circular frame, three clamping and positioning mechanisms, three adjusting mechanisms, multiple fixing structures, and multiple supporting structures.

[0006] The circular frame has a hollow triangular structure in the middle that can cooperate with the triangular stake. The three clamping and positioning mechanisms are evenly distributed in the hollow triangular structure. Each inner wall of the hollow triangular structure is provided with a clamping and positioning mechanism. Each clamping and positioning mechanism is connected to the circular frame through an adjustment mechanism. The clamping and positioning mechanism is used to clamp and position the outer wall of the triangular stake.

[0007] Multiple fixed structures are evenly arranged circumferentially on the circular frame;

[0008] Multiple supporting structures are evenly arranged circumferentially on the outer edge end face of the circular frame.

[0009] Furthermore, the circular frame includes a fixed plate, a thickened base, and three mounting plates. Both the fixed plate and the thickened base are circular structures. The fixed plate is sleeved on the outer end face of the thickened base, and the three mounting plates are evenly distributed on the inner side of the thickened base. The triangular hollow structure is located between the three mounting plates. The mounting plate is provided with a first slot for installing the adjustment mechanism, and the thickened base is provided with a second slot for placing the adjustment part of the adjustment mechanism.

[0010] Furthermore, the adjustment mechanism includes a threaded sleeve, a telescopic screw, and an adjustment part. The telescopic screw is disposed in the first slot, and its inner end is connected to the clamping and positioning mechanism. The outer end of the telescopic screw is threadedly engaged with the threaded sleeve. One side of the threaded sleeve is disposed in the second slot, and the other side of the threaded sleeve is rotatably engaged with the thickened base. The adjustment part is disposed at the end of the threaded sleeve.

[0011] Furthermore, the clamping and positioning mechanism includes a fixed base, a positioning plate, and multiple positioning rollers. The fixed base is disposed on the outer side of the positioning plate and is connected to the telescopic screw. Multiple positioning rollers are arranged on the inner side of the positioning plate.

[0012] Furthermore, the adjustment mechanism also includes two guide rods, which are symmetrically arranged on both sides of the telescopic screw. One end of each guide rod is connected to the fixed base, and the other end of each guide rod is slidably engaged with the thickened base. Each guide rod is provided with a corresponding positioning spring.

[0013] Furthermore, the fixing structure includes fixing bolts and a strip hole, the strip hole being disposed on the fixing plate, and the fixing bolt being disposed within the strip hole.

[0014] Furthermore, the support structure includes a support plate and locking bolts, the inner end of the support plate is fixedly connected to the outer wall of the fixing plate, and the locking bolts are disposed on the support plate.

[0015] Compared with the prior art, the positioning device for triangular stakes described in this utility model has the following advantages:

[0016] 1. The clamping and positioning mechanism uses multiple positioning rollers evenly distributed on the surface of the pipe pile to accurately clamp and support the triangular pile, achieving stable positioning and reducing deviations caused by pile swaying. The positioning rollers feature a smooth design, which effectively reduces frictional wear on the pipe pile surface during clamping, extending the service life of the pile.

[0017] 2. The adjustment mechanism consists of a threaded sleeve, a telescopic screw, and an adjustment section. It can be flexibly adjusted according to pipe piles of different sizes, making it highly adaptable. Through the threaded engagement mechanism, the adjustment mechanism can achieve precise control over the position of the clamping and positioning mechanism, thereby ensuring accurate positioning of the pipe pile.

[0031] Four fixing structures 300 are evenly arranged around the circumference of the circular frame; each fixing structure 300 includes fixing bolts and slotted holes, the slotted holes are located on the fixing plate 101, and the fixing bolts are located inside the slotted holes.

[0032] Eight support structures 200 are evenly arranged circumferentially on the outer edge of the circular frame. Each support structure 200 includes a support plate and locking bolts. The inner end of the support plate is fixed to the outer wall of the fixing plate 101, and the locking bolts are located on the support plate.

[0033] The circular frame includes a fixing plate 101, a thickened base 102, and three mounting plates 103. Both the fixing plate 101 and the thickened base 102 are circular structures. The fixing plate 101 is fitted onto the outer end face of the thickened base 102, and the three mounting plates are evenly distributed on the inner side of the thickened base 102. A triangular hollow structure is located between the three mounting plates 103. Each mounting plate 103 has a first slot for mounting the adjustment mechanism 400, and the thickened base 102 has a second slot 411 for placing the adjustment part 420 of the adjustment mechanism 400.

[0036] How this example works

[0037] Step 1: Check the integrity of the positioning device, confirming that the circular frame, clamping and positioning mechanism 500, adjusting mechanism 400, fixing structure 300, and supporting structure 200 are all undamaged. The fixing plate 101, thickened base 102, and mounting plate 103 are integrated into a single structure.

[0038] Step 2: Place the triangular pile into the hollow triangular structure in the middle of the device, ensuring it is roughly centered. Ensure the pile fits snugly against the hollow triangular structure to prepare for subsequent clamping.

[0039] Step 3: Adjust the position of each clamping and positioning mechanism 500 so that it is aligned with each surface of the pipe pile.

[0040] Step 4: Perform fine adjustments by rotating the threaded sleeve. Using the adjustment mechanism 400, adjust the clamping force via the telescopic screw 410 until the positioning roller 530 gently contacts the surface of the pipe pile. Ensure the clamping and positioning mechanism 500 firmly fixes the pipe pile in the correct position. Confirm the smoothness of the guide rod 430 during sliding and maintain proper pressure balance using the positioning spring.

[0041] Step 5: Using the fixing bolts in the fixing structure 300, fasten the entire device to the designated position through the slotted holes to ensure stability. Secure the support plate with the locking bolts on the support structure 200 to enhance the stability and durability of the entire device.

[0042] Step Six: Check if the verticality and position of the pipe piles meet the design requirements, ensuring all parameters are accurate. After completing all checks, confirm the device is functioning normally and prepare for the next construction operation.
