Description

Technical Field

[0001] This utility model relates to the field of steel pipe column hoisting technology, and in particular to a hoisting tool for tower-mounted steel pipe structures. Background Technology

[0002] Steel trestle bridges and steel pipe supports are common construction techniques in road and bridge engineering. They offer advantages such as good load-bearing performance, convenient connection, and reusability. However, they are also among the parts most prone to safety accidents during construction. After processing, steel pipe columns often require hoisting for subsequent construction. However, the steel pipe columns themselves typically lack designated hoisting positions. Past construction methods often involved temporarily welding several hoisting points onto the steel pipe columns, but this approach has the following problems:

[0003] (1) The surface of the steel pipe is originally coated, but welding the hanging points will damage the original coating and affect the protective effect of the coating.

[0004] (2) Welding operations often affect the mechanical properties of steel pipe columns, thus affecting their load-bearing capacity.

[0005] Sometimes, the steel pipe columns are hoisted by directly securing them with knotted nylon cloth, but this method also has the following problems:

[0006] (1) The curved surface of the steel pipe is difficult to position, and the nylon cloth is difficult to fix on the steel pipe column;

[0007] (2) As the hoisting height increases, the nylon cloth is prone to rotation and sliding during the hoisting process due to the increased influence of wind. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the present invention provides a hoisting tool for steel pipe structures for towers, so as to solve the technical problems mentioned in the background.

[0009] This utility model provides a hoisting tool for a steel pipe structure for tower fastening, including:

[0010] The base plate includes a hoisting section and two installation sections integrally connected to opposite ends of the hoisting section, each of the installation sections having an installation hole for detachable connection with a flange of a steel pipe column;

[0011] A hoisting plate is vertically mounted on the hoisting section and the two installation sections, with the opposite ends of the hoisting plate extending toward the opposite ends of the two installation sections, respectively.

[0012] The lifting hole is horizontally opened at the middle of the lifting plate and extends through the opposite side of the lifting plate.

[0013] Furthermore, the lifting plate is provided with annular reinforcing rings at the middle of opposite sides, and the lifting hole penetrates the lifting plate and the annular reinforcing rings.

[0014] Furthermore, the opposite sides of the hoisting plate are provided with multiple reinforcing plates, and the height of each reinforcing plate gradually decreases from the side closest to the hoisting plate to the outer end.

[0015] Furthermore, the side of the hoisting plate that faces away from the hoisting section and the two installation sections is arc-shaped.

[0016] Furthermore, the height of the hoisting plate gradually decreases from the middle to both ends.

[0017] Furthermore, the hoisting section and the two installation sections are integrated to form an "I" shape.

[0018] Furthermore, each of the mounting sections is provided with two mounting holes, which are located on both sides of the lifting plate.

[0019] Furthermore, the mounting holes are bolt holes, so that the base plate can be installed together with the flange of the steel pipe column by bolts.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The new utility model of a steel pipe structure hoisting tool for towers is simple in structure and easy to use. It provides fixed hoisting points that will not damage the surface of the column, effectively improving the safety and construction speed of hoisting operations.

[0022] This utility model relates to a hoisting tool for steel pipe structures. During hoisting, fasteners are first used to connect the two mounting sections of the base plate to the flanges of the steel pipe column through the mounting holes. This connection is not only firm and reliable but also effectively avoids damage to the surface of the steel pipe column. Then, the hoisting slings (nylon or steel chains) can be passed through the hoisting holes in the middle of the hoisting plate, or the slings (nylon or steel chains) can be directly used to lift the base plate by wrapping them around the hoisting sections and the hoisting plate. After hoisting into place, the hoisting tool and fasteners can be removed for easy reuse. Attached Figure Description

[0030] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0031] In the description of this utility model, it should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and to facilitate understanding and reading. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives of this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0032] like Figure 1-2 As shown, an embodiment of this utility model provides a hoisting tool for a steel pipe structure, including a base plate 10 and a hoisting plate 20. The base plate 10 includes a hoisting section 11 and two installation sections 12 integrally connected to opposite ends of the hoisting section 11. Each installation section 12 is provided with an installation hole 13 for detachable connection with a flange 60 of a steel pipe column. The hoisting plate 20 is vertically disposed on the hoisting section 11 and the two installation sections 12, and the opposite ends of the hoisting plate 20 extend toward opposite ends of the two installation sections 12. At the same time, a hoisting hole 21 is horizontally opened in the middle of the hoisting plate 20, and the hoisting hole 21 penetrates the opposite side of the hoisting plate 20.

[0033] In this embodiment of the utility model, during hoisting, fasteners are first used to connect the two mounting sections 12 of the base plate 10 to the flange of the steel pipe column through the mounting holes 13. This not only ensures a firm and reliable connection but also effectively avoids damage to the surface of the steel pipe column. Then, the hoisting slings (nylon or steel chains) can be passed through the hoisting holes 21 in the middle of the hoisting plate 20, or the slings (nylon or steel chains) can be directly wrapped around the hoisting section 11 of the base plate 10 and the hoisting plate 20 for hoisting. After hoisting to the correct position, the hoisting tools and fasteners are removed for easy reuse.

[0034] Based on the above solutions, such as Figure 1-2 As shown in this embodiment of the present invention, the middle of the opposite side of the lifting plate 20 is provided with annular reinforcing rings 30 respectively. The lifting hole 21 penetrates the lifting plate 20 and the annular reinforcing rings 30. The annular reinforcing rings 30 not only enhance the structural strength and fatigue resistance of the lifting plate 20, but also improve the safety and reliability of the lifting process.

[0035] Specifically, due to the repeated passage of slings (nylon or steel chains) through the lifting hole 21 during long-term use, material fatigue may occur. By setting an annular reinforcing ring 30 around the lifting hole 21, the risk of such fatigue damage is effectively reduced, and the local strength around the lifting hole 21 is significantly enhanced, improving the load-bearing capacity of the entire lifting plate 20 and preventing deformation or tearing when subjected to large tensile forces. At the same time, during the lifting process, especially during lifting and lowering, the lifting tools may be affected by vibration. The annular reinforcing ring 30 can enhance the structure's vibration resistance and reduce stress concentration caused by vibration.

[0036] The annular reinforcing ring 30 can be integrally formed with the lifting plate 20 through casting or welding processes to reduce additional processing steps and simplify the production process.

[0037] Based on the above solutions, such as Figure 1-2 As shown in this embodiment of the present invention, the opposite sides of the lifting plate 20 are provided with a plurality of reinforcing plates 40. The height of each reinforcing plate 40 gradually decreases from the side closest to the lifting plate 20 to the outside. The height of the reinforcing plate 40 gradually decreases from the inside to the outside, forming a trapezoidal support structure. This significantly enhances the overall structural strength of the lifting plate 20 and allows the stress to be distributed more evenly across the entire lifting plate 20, reducing the risk of local stress concentration and extending the service life. In addition, the reinforcing plates 40 are thinner on the outside, reducing unnecessary material usage and lowering the self-weight while ensuring the strength of key parts. The multiple reinforcing plates 40 provide multiple support points, enhancing the bending resistance of the lifting plate 20. Especially when bearing large loads, this prevents the lifting plate 20 from bending or deforming, ensuring that the lifting plate 20 remains stable during the lifting process and avoiding loosening or shaking caused by vibration or impact.

[0038] Specifically, the reinforcing plate 40 can be provided on both sides of the lifting hole 21 to further reduce the concentrated stress around the lifting hole 21 and improve the structural strength around the lifting hole 21.

[0039] Among them, the reinforcing plate 40 can be integrally formed with the lifting plate 20 through casting or welding processes, reducing additional processing steps and simplifying the production process.

[0040] Specifically, such as Figure 1-2 As shown in this embodiment of the utility model, the side of the hoisting plate 20 that is away from the hoisting section 11 and the two installation sections 12 is arc-shaped. The arc-shaped design reduces sharp edges, lowers the risk of collision or scratching with other objects during hoisting, and improves operational safety.

[0041] In another embodiment of this utility model, the height of the lifting plate 20 gradually decreases from the middle to both ends. The design of the middle of the lifting plate 20 being higher concentrates the main force in the middle, while the gradually decreasing height effectively transfers the stress to both ends, achieving a uniform distribution of stress. At the same time, it helps to ensure that the center of gravity of the lifting is located in the center of the lifting tool.

[0042] Specifically, such as Figure 1-2 As shown in this embodiment of the utility model, the hoisting section 11 and the two installation sections 12 are integrally formed into an "I" shape, which not only enhances the strength and stability of the overall structure, but also improves the safety and efficiency of the hoisting process.

[0043] Based on the above solutions, such as Figure 1-2 As shown in this embodiment of the utility model, each of the installation sections 12 is provided with two installation holes 13. The two installation holes 13 are respectively located on both sides of the lifting plate 20, so that the connection part can bear the load more evenly and reduce the risk of excessive force at a single point. Specifically, the installation hole 13 is a bolt 50 hole, so as to install the base plate 10 and the flange 60 of the steel pipe column together with the bolt 50, which facilitates installation and disassembly.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
