Description

Technical Field

[0001] The present invention relates to the manufacture of a cable grid bridge, and in particular to a cable grid bridge system and a manufacturing method. Background Art

[0002] During the construction of the grid bridge, right-angle turns will be encountered; therefore, a turning structure of the grid bridge is required. Specifically, the turning structure of the grid bridge includes an arc-shaped outer rib, a bottom and an arc-shaped inner rib; the bottom includes multiple divergent latitudes and multiple arc-shaped radials, and the direction of the radials is consistent with the direction of the cables.

[0003] There are two solutions:

[0004] 1. Factory prefabrication: The production of grid bridge turning structures requires special equipment and molds. Since the number of turning structures is relatively small, the relative cost of production is higher.

[0005] 2. On-site construction: Cut off the sidewalls at the ends of two straight grid bridges, then butt-join the two perpendicular grid bridges together, overlapping them vertically to support the curved cables. The disadvantages of this method are: 1. On-site cutting is required, which places high demands on the installation workers. 2. Material is wasted in the overlapping areas. Summary of the Invention

[0046] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0047] It should be noted that like reference numerals denote like items in the following drawings, and therefore, once an item is defined in one drawing, it will not be further defined or explained in the subsequent drawings.

These terms are intended solely to facilitate the description of the present invention and to simplify the description, and are not intended to indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction.

[0049] like Figures 1 to 3 As shown, a cable grid bridge system 100, the core component of which is a turning bridge 101. The turning bridge 101 is composed of a plurality of bridge units 10, and these bridge units 10 are arranged and distributed in a divergent shape.

[0050] Specifically, the inner ends of the bridge units 10 are close to each other, forming an inner arc 13, while the outer ends are separated from each other, forming an outer arc 14. This unique technical approach enables the turning bridge 101 to adapt to the laying requirements of cables at turns while ensuring the overall stability and load-bearing capacity of the bridge.

[0051] Each bridge unit 10 is composed of two parallel U-shaped wefts 11 and multiple radial units 12. The U-shaped wefts 11 are composed of outer vertical beams a1, bottom beams a2, and inner vertical beams a3, forming a U-shaped frame structure. The radial units 12 are connected in parallel between the two U-shaped wefts 11, providing support and fixation. These radial units 12 include multiple bottom radial units b2, at least one outer radial unit b1, and at least one inner radial unit b3.

[0052] The bottom radial unit b2 is connected between the bottom beams a2 of the two U-shaped wefts 11, the outer radial unit b1 is connected between the outer vertical beams a1 of the two U-shaped wefts, and the inner radial unit b3 is connected between the inner vertical beams a3 of the two U-shaped wefts 11. This technical approach not only optimizes the structure of the bridge but also improves its load-bearing capacity.

[0053] To further enhance the structural strength and integrity of the turning bridge, the outer diameter wire units b1 of multiple bridge units 10 are interconnected to form a continuous bridge outer diameter wire s1. This continuous outer diameter wire design not only improves the bridge's load-bearing capacity but also enhances the overall appearance of the turning bridge. Furthermore, the inner vertical beams a3 of adjacent bridge units 10 are closely aligned, ensuring a tight connection between the bridge units. The inner diameter wire unit b3 of each bridge unit 10 also has two first end caps r1, which can be further processed or connected according to actual needs.

[0054] At the bottom of the bridge, multiple substantially parallel ribs c are welded between the bottom beams a2 of adjacent bridge units 10. These ribs c seamlessly transition with the corresponding bottom radial units b2 of the bridge units 10, maintaining a consistent curvature, thus forming the bridge bottom radial line s2. The design of the ribs c not only enhances the structural strength of the bridge bottom but also makes the entire bridge more stable when carrying cables, effectively distributing the weight of the cables and preventing deformation or damage caused by excessive local forces.

[0055] Through the above-mentioned structural setting, the cable grid bridge system 100 can not only meet the cable laying requirements at the bends, but also has a high load-bearing capacity and structural stability. At the same time, it simplifies the construction process, reduces the installation difficulty and cost, and is an efficient and practical cable laying solution.

[0056] Preferably, each reinforcing rib c has two second ends r2; each bottom radial unit b2 has two third ends r3, with adjacent second ends r2 and third ends r3 connected in a continuous manner. The arrangement of the second ends r2 of the reinforcing rib c and the third ends r3 of the bottom radial units b2 provides clear connection points for welding or other connection methods.

[0057] The turning bridge 101 includes two interfaces 102 on either side for docking with adjacent bridges. The distance between the two U-shaped wefts 11 of the bridge unit 10 where the two interfaces 102 are located is greater than the distance between the two U-shaped wefts 11 of other bridge units 10. The wider bridge unit 10 provides more space at the interface, allowing the turning bridge 101 to connect more securely with other bridges (such as straight bridges) when docking.

[0058] It should be noted that the bottom diameter unit b2 and the inner diameter unit b3 are straight; this ensures smooth cable routing on the bottom and inside of the cable tray, reducing friction and wear, while ensuring cable stability. The outer diameter unit b1 is curved, better accommodating the natural curvature of the cable at turns.

[0059] In addition, the area between adjacent bridge units 10 is a triangular area v. The triangular structure itself has extremely high stability, can effectively disperse and conduct loads, and reduce deformation or damage caused by excessive local force. The reinforcement ribs c between the bottom beams a2 of each adjacent bridge unit 10 are arc-shaped, which can better adapt to the curved shape of the bridge and provide more uniform support. And the length of the multiple reinforcement ribs c gradually shortens from the outside to the inside. This design is to better adapt to the structural requirements of the straight bridge when it is bent into a curved bridge, ensuring that the force on each part is uniform and the structure is stable during the turning process. This design of reinforcement ribs with varying lengths can perfectly match the curved shape of the bridge, thereby forming a more reasonable mechanical distribution at the corners.

[0060] The triangular area (v) and arc-shaped reinforcement (c) allow the bridge to more flexibly adapt to varying turning radii. This design not only enhances the bridge's structural strength at turns, but also improves the overall flexibility and adaptability of the bridge system, enabling it to better meet the needs of various complex installation scenarios.

[0061] Preferably, there are two outer diameter wire units b1 and two inner diameter wire units b3. Providing two outer diameter wire units b1 can significantly enhance the structural strength of the outer side of the bridge. In the turning bridge 101, the outer side is subjected to greater tensile and bending stresses. The design of the double outer diameter wire units can better disperse and withstand these stresses, thereby improving the overall stability of the bridge. In addition, the two inner diameter wire units b3 can provide more stable support for the inner side of the bridge. The inner side will be subjected to greater pressure when turning. The design of the double inner diameter wire units can effectively disperse these pressures and avoid deformation or damage caused by excessive local force.

[0062] In addition, if Figure 4As shown, this technical solution also includes a straight bridge 103 connected to the turning bridge 101. This technical means enables the turning bridge 101 to be seamlessly connected to the straight bridge 103, thereby realizing continuous laying of cables in different directions and meeting complex cable layout requirements. Figure 6 and Figure 7 As shown, fastening mechanisms 20 are connected between the two sides of the turning bridge 101 and the two sides of the straight bridge 103. The fastening mechanisms 20 are installed between the two sides of the turning bridge 101 and the two sides of the straight bridge 103. This technical means can effectively prevent the bridge from loosening or displacement due to external forces during use.

[0063] like Figure 8 and Figure 9 As shown, each fastening mechanism 20 consists of a metal strip 21 and a plurality of locking mechanisms 22. The metal strip 21 is installed on the outside of the side of the bridge frame, and has a plurality of mounting holes 211 evenly spaced thereon. These mounting holes 211 provide precise mounting positions for the locking mechanisms 22.

[0064] Specifically, the locking mechanism 22 consists of a pressure block 221, a screw 222, and a nut 223. The pressure block 221 fits tightly against the inside of the bridge's side vertical beam. The screw 222 passes through the pressure block 221 and the mounting holes 211 on the metal bar 21 from the inside, and is finally tightened and secured by the nut 223. This structure not only ensures the stability of the connection but also facilitates installation and maintenance, making the entire bridge system more reliable and efficient in practical applications.

[0065] In addition, the technical solution provides an efficient and low-cost method for manufacturing a cable grid bridge system, which is particularly suitable for manufacturing a turning bridge 101 and docking and fixing it with a straight bridge 103. The following are the detailed manufacturing steps:

[0066] 1) Fabricating a turning bridge 101 includes the following steps: 1.1) Preparing a standard straight bridge 103, which includes multiple radial wires 12' and multiple U-shaped weft wires 11. Each U-shaped weft wire 11 consists of an outer vertical beam b1, a bottom beam b2, and an inner vertical beam b3. The radial wires 12' are further divided into outer radial wires 121, bottom radial wires 122, and inner radial wires 123.

[0067] 1.2) Cut from the inner diameter of the bridge 123 toward the outer diameter of the bridge 121, retaining only the outer diameter of the bridge 121. After cutting, the linear bridge 103 is formed with N spaced notches and N+1 independent bridge units 10. Each bridge unit 10 comprises two parallel U-shaped wefts 11 and multiple radial units 12, which are connected in parallel between the two U-shaped wefts 11.

[0068] In this step, to further optimize the cutting process, the following specific operations can be used: the inner diameter line 123 and the bottom diameter line 122 between the second and third U-shaped weft lines 11 are cut off, while the outer diameter line 121 of the bridge is retained, forming the first rectangular gap 01. The inner diameter line 123 and the bottom diameter line 122 between the fourth and fifth U-shaped weft lines 11 are cut off, while the outer diameter line 121 of the bridge is retained, forming the second gap 02.

[0069] 1.3) The cut bridge frame p is bent toward the inner diameter line 123 to form a curved bridge frame 101. Curved bridge frame 101 is composed of multiple bridge frame units 10 arranged in a diverging pattern. The inner ends of the bridge frame units 10 are close together, forming an inner arc, while the outer ends are separated, forming an outer arc. The inner vertical beams a3 of adjacent bridge frame units 10 are closely aligned, and the inner diameter line unit b3 of each bridge frame unit 10 has two first end caps r1.

[0070] 1.4) Multiple substantially parallel reinforcing ribs c are welded between the bottom beams a2 of adjacent bridge units 10. The reinforcing ribs c seamlessly transition with the corresponding bottom radial units b2 of the bridge units 10, maintaining a consistent curvature to form the bridge bottom radial line 122. This design not only enhances the bridge's structural strength but also ensures the stability of the curved bridge under load.

[0071] 2) Connect the turning bridge 101 to the linear bridge 103. The specific steps are as follows: 2.1) Connect the two sides of the turning bridge 101 to the two sides of the linear bridge 103 through the fastening mechanism 20. The specific technical means of the fastening mechanism 20 have been described above and will not be repeated here.
