Description

Technical Field

[0001] This utility model relates to the field of steel pipe tower technology, and in particular to the bottom support structure of steel pipe towers. Background Technology

[0002] Steel pipe towers, as a common type of tall structure, are widely used in power transmission, communication base stations, monitoring, and lighting. The fundamental prerequisite for their structural safety and long-term stable operation is ensuring that the tower maintains a precise vertical position after installation. Achieving this verticality largely depends on the installation accuracy of its base support structure, particularly requiring the bearing surface of the support structure to be absolutely horizontal.

[0003] In existing installation techniques, it is usually necessary to pour a concrete foundation on the construction site and then precisely level the foundation surface. This process not only requires a high level of technical skill from the construction workers and consumes a lot of time, but the curing period of the concrete also seriously affects the progress of the overall project.

[0004] However, due to the complex and variable geological conditions at construction sites and the difficulty in completely avoiding construction errors, the foundation bearing surface often exhibits slight tilting. When this tilting occurs, the traditional remedy is usually to fill the space between the base flange of the steel pipe tower and the foundation with steel gaskets for adjustment. This method heavily relies on the experience of the operators, the adjustment process is cumbersome, requiring repeated hoisting, measurement, and gasket replacement, which is not only inefficient but also difficult to achieve high-precision fine-tuning. It can easily cause uneven stress distribution at the flange connection surface, posing a potential threat to structural safety. Therefore, how to provide a support structure that can quickly, conveniently, and with high precision level the bottom of the steel pipe tower has become an urgent technical problem to be solved in this field. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bottom support structure for steel pipe towers, which aims to improve the problems of difficulty in efficiently and accurately leveling the bottom support structure of steel pipe towers during installation due to uneven foundation, as well as the cumbersome adjustment process, reliance on manual experience, and low adjustment accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bottom support structure for a steel pipe tower, comprising: a first base, a load-bearing component, a second base, and a leveling component.

[0007] The second base is mounted on the load-bearing component; the leveling component is disposed between the first base and the second base.

[0008] The leveling component has an inclined block with a slot inside, and a first sphere and a second sphere connected to a first base and a second base respectively; the first sphere and the second sphere are slidably accommodated in the slot of the inclined block.

[0009] Preferably, the load-bearing component includes a first connecting block, the first connecting block having a groove for accommodating the spiral steel pipe; the load-bearing component also includes a threaded column and a limiting block, the threaded column being threadedly connected to the first connecting block, and its end abutting against the limiting block located in the groove.

[0010] Preferably, the load-bearing component further includes a second flange and a second connecting block; the second flange is disposed between the first connecting block and the second connecting block, and the second connecting block is fixedly connected to the second base.

[0011] Preferably, the leveling component further includes a fixing block fixed on the second base, the second sphere being connected to the fixing block via a second connecting post; and the first sphere being connected to the first base via a first connecting post.

[0012] Furthermore, the first connecting post extends upward through the first base, with its top protruding above the upper surface of the first base.

[0013] Preferably, the inclined block is a wedge-shaped block.

[0014] Preferably, the side of the limiting block facing the spiral steel pipe has an arc-shaped concave surface that matches the outer wall of the spiral steel pipe.

[0015] Preferably, the upper end face of the first base is provided with a first flange for mounting the steel pipe tower body.

[0016] In one specific implementation, the first connecting block and the second connecting block are connected by bolts passing through the second flange.

[0017] This utility model has the following beneficial effects: In this invention, a load-bearing component and a leveling component are provided, which realizes the two-stage leveling function of "coarse adjustment" and "fine adjustment" at the bottom of the steel pipe tower. It can quickly correct large installation errors caused by uneven foundation, and can also perform high-precision fine adjustment, effectively balancing leveling efficiency and final installation accuracy.

[0018] In this invention, a simple lateral driving force is transformed into a precise vertical adjustment, making high-precision leveling operations very simple, reducing reliance on complex construction tools and advanced operator skills, and making it easy to promote and use on site.

[0021] 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.

[0022] Please refer to Figures 1 to 5 This utility model provides a bottom support structure for a steel pipe tower, which aims to solve the problems of tower tilting, difficulty in leveling and adjustment, and low accuracy caused by uneven foundation during the installation of steel pipe towers.

[0023] like Figure 1 As shown, the bottom support structure of the steel pipe tower is used to install the steel pipe tower body 1, including a first base 2 and a load-bearing component 7 connected to a spiral steel pipe 5 buried underground. The upper end face of the first base 2 is provided with a first flange 4 for installing the steel pipe tower body 1.

[0024] The bottom support structure of the steel pipe tower also includes a second base 3, which is fixedly installed on the upper part of the load-bearing component 7; see reference. Figure 2 and Figure 3A leveling component 6 is provided between the first base 2 and the second base 3. The leveling component 6 includes a fixing block 601, a first sphere 602, a first connecting post 603, a second connecting post 604, a second sphere 605, a slot 606, and a wedge block 607. The fixing block 601 is fixedly connected to the upper surface of the second base 3. The second sphere 605 is connected to the fixing block 601 through the second connecting post 604. The first sphere 602 is connected to the first base 2 through the first connecting post 603. The wedge block 607 is a wedge-shaped block with a slot 606 inside. The first sphere 602 and the second sphere 605 are slidably accommodated in the slot 606 of the wedge block 607. The first connecting post 603 passes upward through the first base 2, and its top protrudes from the upper surface of the first base 2.

[0025] Reference Figure 4 and Figure 5 The load-bearing component 7 includes a threaded post 701, a first connecting block 702, a limiting block 703, a second flange 704, and a second connecting block 705. The first connecting block 702 has a groove for accommodating the spiral steel pipe 5. The threaded post 701 is threadedly connected to the first connecting block 702, and its end abuts against the limiting block 703. The limiting block 703 is located in the groove, and the side of the limiting block 703 facing the spiral steel pipe 5 is an arc-shaped concave surface adapted to the outer wall of the spiral steel pipe 5. The second flange 704 is disposed between the first connecting block 702 and the second connecting block 705. The first connecting block 702 and the second connecting block 705 are connected by bolts passing through the second flange 704. The second connecting block 705 is fixedly connected to the bottom of the second base 3.

[0026] As a preferred solution, by hammering the top of the first connecting column 603, the first ball 602 causes the inclined block 607 to slide laterally. Since the inclined block 607 is a wedge-shaped block, its lateral displacement will force the first ball 602 and the second ball 605 to produce relative vertical displacement within the slot 606, thereby causing the first base 2 to undergo precise tilt adjustment relative to the second base 3. During installation, if a large tilt occurs, the angle between the first connecting block 702 and the second connecting block 705 can be coarsely adjusted by adding or removing shims between the connecting surfaces of the second flange 704, so as to quickly correct large installation errors. By rotating the threaded column 701, its threaded transmission causes the limiting block 703 to move towards the outer wall of the spiral steel pipe 5 and finally press it tightly. By utilizing the large area contact between its arc-shaped concave surface and the outer wall of the spiral steel pipe 5, a sufficiently large frictional force is generated to achieve a firm lock on the spiral steel pipe 5.

[0027] Working Principle: During installation and use of the bottom support structure of the new steel pipe tower, the spiral steel pipe 5 is first drilled into the ground to form a foundation. Then, the load-bearing component 7 is installed on the spiral steel pipe 5, that is, the groove of the first connecting block 702 is aligned with the spiral steel pipe 5 and inserted. Then, the threaded column 701 is rotated, and the limiting block 703 is moved inward through threaded transmission until it is tightly pressed against the outer wall of the spiral steel pipe 5 to achieve locking. If the load-bearing component 7 tilts significantly due to uneven ground, initial leveling can be achieved by adjusting the connection between the second flange 704 and the first connecting block 702 and the second connecting block 705. Then, the second base 3, which is fixed with the leveling component 6, is installed on the load-bearing component 7. When further adjustments are needed... When the first base 2 is leveled with high precision, a lateral striking force is applied to the top of the first connecting column 603. This force drives the first ball 602 and the second ball 605 to undergo lateral displacement within the slot 606 of the inclined block 607. Since the inclined block 607 is a wedge-shaped structure, its inclined inner wall converts the lateral displacement into a small vertical relative displacement between the first ball 602 and the second ball 605. This causes the first base 2 connected to the first ball 602 to tilt precisely relative to the fixed second base 3. This is done by continuous fine-tuning until the first base 2 reaches a completely horizontal state. Finally, the steel pipe tower body 1 is installed on the precisely leveled first base 2 through the first flange 4, completing the entire installation process.

[0028] 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. 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.
