It includes a main body, a rotator at the top of the main body, helical blades on the outer wall of the main body, a quick-release assembly on the outer wall of the main body, and a quick-installation assembly. The quick-release assembly includes a locking block, the bottom end of which is fixedly connected to the top of the main body.

Description

Technical Field

[0001] This utility model relates to the field of spiral anchor technology, and in particular to a spiral anchor foundation for power transmission towers that can be quickly disassembled and assembled. Background Technology

[0002] In the field of power transmission tower foundation construction, the connection method between the helical anchor foundation structure and the rotator has a significant impact on construction efficiency and installation quality. To achieve rapid and reliable installation of the helical anchor, a specialized foundation structure is typically required. This structure usually includes the anchor bolt body, connection interfaces, and auxiliary functional modules such as torque transmission. Especially under complex geological conditions, with varying anchoring depths, the ease of assembly and disassembly of the foundation structure and rotator directly affects construction efficiency and installation accuracy. Therefore, developing a helical anchor foundation structure with rapid assembly and disassembly capabilities and simple operation has become an important direction for the technological improvement of power transmission tower construction equipment.

[0003] In existing technologies, the spiral anchor foundation structure used in transmission tower construction generally includes an anchor bolt body, a fixed connector, and a torque transmission component. Structurally, the structure includes an interface for connecting the rotator, using multiple bolts or welding for rigid connection; it is also equipped with an anti-loosening device to ensure reliable torque transmission. However, in practical use, the lack of quick-assembly / disassembly functionality means that multiple fasteners must be removed when replacing the rotator. Furthermore, the connection interface and transmission components are mostly fixed structures, making disassembly and assembly inconvenient and time-consuming. This prevents rapid adaptation to different construction conditions, severely impacting the efficiency and flexibility of tower foundation construction.

[0004] However, existing helical anchor foundation structures still have certain problems in practical applications. On the one hand, they need to be fixed to the rotator during drilling, and traditional structures cannot be fixed quickly, affecting the efficiency of helical anchor installation. On the other hand, the helical blades cannot be installed quickly. These problems reduce the operational efficiency of the helical anchor foundation structure, and there is an urgent need to optimize the structural design. To address these issues, a helical anchor foundation for transmission towers that can be quickly assembled and disassembled is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick-assembly and disassembly spiral anchor foundation for power transmission towers, aiming to improve the problem in the prior art where spiral anchors cannot be quickly fixed to the rotator, affecting the installation of spiral anchors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a spiral anchor foundation for transmission towers that can be quickly disassembled and assembled, comprising a main body, a rotator provided at the top of the main body, a spiral blade provided on the outer wall of the main body, a quick-release assembly provided on the outer wall of the main body, and a quick-installation assembly provided on the outer wall of the main body;

[0007] The quick-release assembly includes a locking block, the bottom end of which is fixedly connected to the top end of the main body. A fixing ring is fixedly connected to the outer wall of the main body, and a sliding ring is slidably connected to the outer wall of the main body. A limiting post is fixedly connected to the top end of the sliding ring. A spring is sleeved on the outer wall of the limiting post. One end of the spring is fixedly connected to the bottom end of the fixing ring, and the other end of the spring is fixedly connected to the top end of the sliding ring. The outer wall of the limiting post slides inside the rotator. A recess is fixedly connected inside the rotator, and the outer wall of the locking block slides on the inner wall of the rotator.

[0008] As a further description of the above technical solution:

[0009] The quick-installation assembly includes a slider, the outer wall of which is slidably connected to the inner wall of the main body.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the main body is fixedly connected to an outer wall ring, and the inner wall of the main body is fixedly connected to a column.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the column is fitted with a second spring, one end of which is fixedly connected to one end of the slider, and the other end of which is fixedly connected to the inside of the main body.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the main body is provided with an outer column, and the spiral plate is fixedly connected to the outer wall of the outer column.

[0016] As a further description of the above technical solution:

[0017] The bottom end of the outer wall ring is fixedly connected to a folding column, and the outer wall of the folding column slides inside the outer column.

[0018] As a further description of the above technical solution:

[0019] The bottom end of the first folding column is rotatably connected to a rotating column, and the outer wall of the rotating column is fixedly connected to a second folding column.

[0020] As a further description of the above technical solution:

[0021] The outer wall of the slider slides on the outer wall of the outer column, and the outer wall of the second folding column slides inside the outer column.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the main body and the locking block are first inserted into the rotator. The sliding ring is pulled down to pull out the limiting post and stretch the first spring, releasing the limiting of the fixing ring. The main body is rotated so that the locking block slot slides along the concave block. After reaching the designated position, the sliding ring is released, and the first spring rebounds to push the limiting post back to its original position. This achieves the rotational limiting of the main body and the vertical limiting of the concave block on the locking block, achieving the effect of quick assembly and disassembly of the main body and the rotator. It solves the problem that the spiral anchor cannot be quickly fixed to the rotator, which affects the installation of the spiral anchor and improves the convenience of spiral anchor installation.

[0024] 2. In this utility model, the outer column is first slid into the main body, and the first folding column is inserted at the same time. When the outer column slides, it compresses the slider and the second spring. After sliding past the slider, the second folding column is rotated to a horizontal position, and the outer column is pushed down so that its bottom end contacts the top end of the second folding column. The second spring rebounds and drives the slider to reset. The bottom end of the slider slides past the top end of the outer column to complete the fixation, which achieves the effect of quickly installing the spiral blade. This solves the problem that the spiral anchor cannot quickly install the spiral blade, which affects the drilling efficiency of the spiral anchor, and improves the practicality of the spiral anchor.

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 Figures 1-3 This utility model provides an embodiment of a quick-disassembly spiral anchor foundation for power transmission towers, comprising a main body 2, which serves as the core structure of the spiral anchor. The main body 2 is made of high-strength steel and has excellent bending and compressive strength, which is existing technology and will not be described in detail here. A rotator 1 is provided at the top of the main body 2, which serves as a power transmission device. The rotator 1 is forged from alloy steel and nitrided on the surface, resulting in high hardness and wear resistance. It has a drive groove inside that matches the locking block 3, which is common knowledge and will not be described in detail here.

A quick-installation assembly is provided on the outer wall of the main body 2 for quick installation of the spiral blades 9.

[0036] The quick-release assembly includes a locking block 3, which serves as a key connecting component. The locking block 3 is precision-machined from tempered steel, forming a precise fit with the rotator 1 to ensure effective torque transmission. The bottom end of the locking block 3 is fixedly connected to the top end of the main body 2. A fixing ring 6 is fixedly connected to the outer wall of the main body 2, and a sliding ring 5 is slidably connected to the outer wall of the main body 2. The sliding ring 5 serves as an operating ring, with a knurled surface for anti-slip purposes, facilitating operation by construction personnel. This is common knowledge and will not be elaborated further here. A limiting post 7 is fixedly connected to the top end of the sliding ring 5. A spring 8 is fitted onto the outer wall of the limiting post 7. One end of the spring 8 is fixedly connected to the bottom end of the fixing ring 6, and the other end is fixedly connected to the top end of the sliding ring 5. The outer wall of the limiting post 7 slides inside the rotator 1. A recess 4 is fixedly connected inside the rotator 1, serving as a limiting component. The recess 4 is made of high-carbon chromium bearing steel and engages with the slot inside the locking block 3, thereby locking the main body 2. The outer wall of the locking block 3 slides on the inner wall of the rotator 1.

[0037] Reference Figures 4-7The quick-installation assembly includes a slider 14, which is used to lock the outer column 17. The slider 14 is made of alloy steel with quenching treatment, resulting in extremely high surface hardness and excellent wear resistance and impact resistance. The outer wall of the slider 14 is slidably connected to the inner wall of the main body 2. An outer wall ring 10 is fixedly connected to the outer wall of the main body 2. The outer wall ring 10 cooperates with the slider 14 to guide the movement. The inner hole is provided with a hardened guide groove to ensure the accurate installation position of the outer column 17, achieving the effect of precise installation of the spiral plate 9. A column 15 is fixedly connected inside the main body 2. The column 15 serves as a spring guide shaft. The column 15 is made of steel with precision grinding and hard chrome plating, making it wear-resistant and corrosion-resistant. This is existing technology and will not be described in detail here. A second spring 16 is sleeved on the outer wall of the column 15. One end of the spring 14 is fixedly connected to one end of the slider 14, and the other end of the spring 16 is fixedly connected to the inside of the main body 2. The outer wall of the main body 2 is provided with an outer column 17, which serves as the mounting base for the spiral plate 9. The outer column 17 is made of seamless steel pipe and the outer surface is treated with hot spray zinc, which has excellent corrosion resistance. The spiral plate 9 is fixedly connected to the outer wall of the outer column 17. The bottom end of the outer wall ring 10 is fixedly connected to a folding column 11. The outer wall of the folding column 11 slides inside the outer column 17. The bottom end of the folding column 11 is rotatably connected to a rotating column 13. The outer wall of the rotating column 13 is fixedly connected to a folding column 12. The folding column 11 cooperates with the folding column 12 to perform folding motion. The outer wall of the slider 14 slides on the outer wall of the outer column 17, and the outer wall of the folding column 12 slides inside the outer column 17.

[0038] Working principle: When using this spiral anchor, it needs to be connected to the rotator 1. First, insert the main body 2 and the locking block 3 into the rotator 1. At this time, the limiting post 7 is also inserted into the rotator 1. Then, pull down the sliding ring 5. Pulling the sliding ring 5 at the same time will pull the limiting post 7 out of the rotator 1 and stretch the spring 8, thus canceling the rotation limitation of the limiting post 7 on the main body 2 and the fixing ring 6. Then, rotate the main body 2 to make the locking groove inside the locking block 3 slide outside the concave block 4. After rotating to the designated position, release the sliding ring 5. Under the rebound action of the spring 8, the limiting post 7 will be pulled out of the rotator 1. Position post 7 is reset. At this time, position post 7 reaches the rotation limit of the main body 2, and concave block 4 reaches the vertical limit of the locking block 3. When the spiral anchor needs to be removed, first pull down the sliding ring 5. While pulling the sliding ring 5, the position post 7 is pulled out of the inside of the rotator 1 and the spring 8 is stretched. The rotation limit of position post 7 on the main body 2 and the fixing ring 6 is canceled. Then rotate the rotator 1, which drives the concave block 4 to rotate into the slot opened in the locking block 3. Then pull the rotator 1 upward to separate the rotator 1 and the main body 2, thus achieving the effect of quick disassembly and assembly of the main body 2 and the rotator 1.

[0039] When the spiral plate 9 needs to be installed, first slide the outer column 17 along the outer wall of the main body 2, and at the same time insert the folding column 11 into the outer column 17. During the sliding process, the outer column 17 compresses the slider 14 inward, and the slider 14 compresses the spring 16 at the same time. After the outer column 17 slides past the outer wall of the slider 14, rotate the folding column 12 to a horizontal state and slide the outer column 17 downward so that its bottom end contacts the top end of the folding column 12. At this time, the spring 16 rebounds and pushes the slider 14 to reset. The bottom end of the slider 14 slides past the top end of the outer column 17, achieving the effect of quickly installing the spiral plate 9.
