Description

Technical Field

[0001] This utility model relates to the field of foundation treatment technology, and in particular to a spiral steel pile auxiliary pile forming device. Background Technology

[0002] Spiral steel piles are a common type of pile foundation used for foundation reinforcement, infrastructure construction, and engineering support. Made of steel pipes and steel materials, they are typically spiral-shaped, resembling a screw. Their structure allows them to quickly and effectively penetrate different types of soil layers, much like screwing into the ground. In desert and sandy land, a supporting device is used for the installation of spiral steel piles. This device primarily addresses the accurate determination of the pile location while maintaining the vertical stability of the pile. It ensures firm rooting and support in low-bearing desert and sandy land, preventing quality problems such as tilting and misalignment during the downward construction process. This guarantees sufficient bearing capacity and stability for the spiral steel piles, providing a solid foundation for subsequent photovoltaic support installation.

[0003] The existing structure of some spiral steel pile auxiliary pile forming devices mainly includes a pile body, a drive device, a rotating spiral cutter head, a guide device, and a stable support frame. Its working principle is that the drive device drives the spiral cutter head to rotate, inserting the spiral steel pile into the ground. The rotation of the spiral cutter head causes the pile body to cut in the soil. At the same time, the spiral propulsion force gradually pushes the pile body to the design depth. The auxiliary pile forming device ensures the efficiency and accuracy of pile foundation construction by providing stable support and precise control. It is suitable for various soil conditions, especially soft soil and medium-density soil layers.

[0004] However, in practical use, some pile-forming equipment often relies on manual measurement and experience-based judgment, which affects the positioning accuracy of the piles and can easily lead to pile tilting and deviation from the design position. Especially under complex geological conditions, the looseness and unevenness of the soil further increase the construction difficulty, making it impossible for the piles to maintain an ideal vertical state. This not only affects the bearing capacity of the pile foundation but also causes instability and safety hazards in subsequent structures. To address the above-mentioned problems, a spiral steel pile auxiliary pile-forming device is proposed. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 , Figure 2This utility model provides an embodiment of a spiral steel pile auxiliary pile-forming device, including a pile-forming auxiliary frame 1. The pile-forming auxiliary frame 1 has an overall frame structure and is made of high-strength carbon steel.

A pile-forming mechanism is fixedly connected to the top of the pile-forming auxiliary frame 1, and a first fixed protective shell 2 is fixedly connected to the rear side of the pile-forming auxiliary frame 1. The first fixed protective shell 2 is cuboid in shape and made of aluminum alloy. The aluminum alloy material ensures a certain strength, has a light weight, and also has good corrosion resistance, which can effectively protect the internal positioning mechanism from the influence of the external environment. The positioning mechanism is fixedly connected inside the first fixed protective shell 2.

[0036] A return assembly is fixedly connected to the top of the sliding connecting block 6. The return assembly includes two fixed connecting blocks 7, which are rectangular blocks made of carbon steel with high strength. The bottom of the fixed connecting blocks 7 is fixedly connected to the top of the two sliding connecting blocks 6. A connecting spring post 8 is fixedly connected to the outer side of the two fixed connecting blocks 7, i.e., the side away from the two fixed connecting blocks 7. The connecting spring post 8 is cylindrical with high elastic limit and fatigue strength. A return spring 9 is sleeved on the outside of the connecting spring post 8. When the sliding push block 5 pushes the sliding connecting block 6 to move... When the external force is applied, the return spring 9 undergoes elastic deformation, storing energy. When the external force disappears, the return spring 9 releases the energy, pushing the sliding connecting block 6 to reset. The left and right ends of the return spring 9 are fixedly connected to the side of the two fixed connecting blocks 7 that is close to each other, i.e., the side away from the two fixed connecting blocks 7. The outside of the return spring 9 is slidably connected to the top of the two sliding connecting blocks 6.

The connecting clamping plates 11 are externally fixedly connected to the outside of the protective sliding connecting plate 10. The connecting clamping plates 11 are externally fixedly connected to a protective sponge pad 12. The protective sponge pad 12 is rectangular and provides stable clamping for the vertical spiral steel pile 16, while also serving as a buffer and protection to prevent damage to the surface of the steel pile. The side of the two protective sponge pads 12 that is close to each other, i.e. the side that is far away from the two protective sponge pads 12, is slidably connected to the outside of the vertical spiral steel pile 16.

[0038] Reference Figure 3 , Figure 4 The positioning mechanism includes a screw drive motor 13, a key component for positioning and pressing the vertical helical steel pile 16. The internal motor windings are made of high-quality copper wire, which has good conductivity and can effectively improve the working efficiency of the motor. When the device is working, the screw drive motor 13 starts working after being powered on, and its drive end generates rotational power. The bottom of the screw drive motor 13 is fixedly connected to the top of the pile-forming auxiliary frame 1. The drive end of the screw drive motor 13 is fixedly connected to a connecting shaft 14. The connecting shaft 14 is cylindrical and made of alloy steel, which has high strength and good wear resistance. It can withstand the torque and centrifugal force generated when the screw drive motor 13 is driven, ensuring that it will not deform or be damaged during long-term use. The outside of the connecting shaft 14 is fixedly connected to a pressing and transferring disc 15. The pressing and transferring disc 15 is circular. Under the drive of the screw drive motor 13, the pressing and transferring disc 15 rotates and presses the vertical helical steel pile 16 downward, providing power for the driving of the steel pile. The bottom of the pressing and transferring disc 15 is slidably connected to the vertical helical steel pile 16.

[0039] A cleaning mechanism is fixedly connected to the rear side of the pile-forming auxiliary frame 1.

Drive components are fixedly connected to the left and right sides of the interior of the second fixed protective shell 17 by bolts. The drive components include a DC motor 18, which is fixedly connected to the interior of the second fixed protective shell 17. A rotating connecting column 19 is fixedly connected to the drive end of the DC motor 18. The exterior of the DC motor 18 is tightly fixed to the interior of the second fixed protective shell 17 by bolts. The drive end of the DC motor 18 is fixedly connected to the rotating connecting column 19 via a high-precision coupling. The exterior of the rotating connecting column 19 is rotatably connected to the interior of the second fixed protective shell 17.

[0040] Both the left and right sides of the interior of the second fixed protective housing 17 are rotatably connected to connecting rod assemblies. Each connecting rod assembly includes a rotating connecting plate 20, which is rectangular in shape. The outside of the rotating connecting plate 20 is rotatably connected to one side of the interior of the second fixed protective housing 17 via a shaft and bearing rotatable connection structure, allowing it to rotate around the connecting shaft 14. The outside of the rotating connecting plate 20 is also rotatably connected to one side of the interior of the second fixed protective housing 17. A rotating transmission plate 21, also rectangular in shape and made of aluminum alloy, is rotatably connected to the outside of the rotating connecting plate 20, providing good strength and flexible rotation. The rotating transmission plate 21, driven by the rotating connecting plate 20, can rotate and swing to a certain extent. The external part of the rotating transmission plate 21 is rotatably connected to the inside of the U-shaped fixing block 22. The internal part of the second fixed protective shell 17 is rotatably connected to a rotating storage plate 23. The rotating storage plate 23 is rectangular, made of aluminum alloy, and anodized, possessing good strength and rotational flexibility. The top of the rotating storage plate 23 is fixedly connected to the U-shaped fixing block 22. The piling mechanism includes a cylinder 3, which is cylindrical and contains components such as a piston and piston rod. It drives the piling mechanism through the input and output of compressed air. The piston rod performs linear reciprocating motion. During operation, by controlling the intake and exhaust of compressed air, the drive end of cylinder 3 generates linear thrust. Cylinder 3 is externally fixedly connected to the rear side of the pile-forming auxiliary frame 1. A connecting telescopic column 4 is fixedly connected to the drive end of cylinder 3. The connecting telescopic column 4 is a slender cylindrical shape, made of alloy steel, possessing high strength and good wear resistance, capable of withstanding the tensile and compressive forces generated during cylinder 3's operation, ensuring no deformation or damage during long-term use. A sliding push block 5 is fixedly connected to the outside of the connecting telescopic column 4. The sliding push block 5 is a rectangular block, realizing... The bottom of the sliding push block 5 is precisely slidably connected to the guide rail inside the first fixed protective shell 2 via a slider installed at the bottom. The left and right sides of the outside of the sliding push block 5 are slidably connected to the side of the two sliding connecting blocks 6 that is close to each other, i.e., the side away from the outside of the two sliding connecting blocks 6. The bottom of the sliding push block 5 is slidably connected to the inside of the first fixed protective shell 2. There are two sliding connecting blocks 6 slidably connected inside the pile forming auxiliary frame 1. The sliding connecting blocks 6 are rectangular blocks made of aluminum alloy, which has good strength and is relatively lightweight. The top of the sliding connecting blocks 6 is connected by welding.

[0041] Working principle: First, when cylinder 3 is activated, the piston inside cylinder 3 generates linear thrust through the input and output of compressed air, pushing the connecting telescopic column 4 forward. This forward movement of the connecting telescopic column 4 causes the sliding push block 5 to move forward as well. The design of the sliding push block 5 allows it to achieve precise forward movement and positioning with the assistance of the sliding connecting block 6. When compressed, the sliding connecting blocks 6 on both sides of the sliding push block 5 can smoothly slide along the grooves inside the first fixed protective shell 2. This process ensures that the connecting clamping plate 11 can effectively clamp the vertical spiral steel pile, thereby achieving precise positioning during pile formation, ensuring the pile remains vertical, and preventing tilting.

[0042] The DC motor 18 starts, driving the rotating connecting column 19 to rotate. This rotation of the column causes the connected rotating connecting plate 20 to rotate accordingly, transmitting the power generated to the rotating transmission plate 21. The movement of the transmission plate 21 then causes the rotating storage plate 23 to rotate, effectively dumping the soil generated during pile formation into the second fixed protective shell 17. This improves soil handling efficiency and significantly reduces the workload of subsequent workers, making pile formation more efficient and convenient. It achieves precise control of the pile position and effective soil removal, improving the overall efficiency and quality of pile formation and demonstrating good practicality and innovation.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
