Description

Technical Field

[0001] The utility model relates to a cable bearing device, in particular to a metal wire grid bridge frame and a grid bridge frame system for bearing cables. The metal wire grid bridge frame can be assembled by end-to-end splicing into a continuously extended grid bridge frame system. Background Art

[0002] Grid trays are commonly used in construction and industrial settings to support and organize cables, wires, pipes, and other wiring systems. They are made of metal wires that form a grid-like structure.

[0003] For example, the US invention patent with the authorization announcement number US6239364B1 discloses a metal wire mesh bridge that can be easily connected together without using additional parts. This metal wire mesh bridge is composed of a plurality of longitudinal bars and a plurality of U-shaped cross bars that are spot welded. The cross bar at one end of the mesh bridge is slightly smaller, and the other end has two U-shaped cross bars that are closer. When splicing the ends, the slightly smaller cross bar is embedded between the two U-shaped cross bars that are closer.

[0004] For another example, the U.S. invention patent with authorization publication number US8250717B2 discloses another grid bridge frame, in which two U-shaped cross bars with a closer distance are arranged at the end of the slightly smaller side, and a U-shaped cross bar is arranged at the other end. At the same time, multiple bent arch structures are arranged on the two U-shaped cross bars. When splicing the ends, a U-shaped cross bar is embedded between two slightly smaller and closer U-shaped cross bars. The arch structure can limit the clamped U-shaped cross bar from escaping from the gap, thereby further increasing the reliability of the grid bridge frame after splicing.

[0005] The above-mentioned metal wire mesh bridge has the following problems: 1. The design of the arch structure will add a more troublesome arch bending process on the U-shaped cross bar, and the arch structure increases the process requirements for welding between the U-shaped cross bar and the longitudinal trunk; 2. In the processing process of arch bending of the U-shaped cross bar, cracks are easily generated in the arched part, which will reduce the structural strength and reliability of the grid bridge connection. This kind of grid bridge is connected end to end. If one of the connection sections becomes loose and collapses, it will produce a linkage effect, causing the connection structure of the entire grid bridge system to be destroyed. Utility Model Content

[0077] Embodiment 1:

[0078] like Figures 1 to 11 Shown is a wire mesh bridge 100 for carrying cables provided in this embodiment, and a mesh bridge system 200 formed by connecting the wire mesh bridge 100 for carrying cables provided in this embodiment front to back end to end.

[0079] like Figure 1 and Fig.10 As shown, a wire mesh bridge 100 for carrying cables is formed into a mesh shape by connecting a plurality of warps 101 and a plurality of U-shaped wefts 102 by spot welding. The head end of the wire mesh bridge 100 for carrying cables is a clamping end 10, and the warps 101 are bent inwardly at the clamping end 10 to form a narrowing portion 20. The clamping end 10 includes two first U-shaped wefts 11 and second U-shaped wefts 12 close to each other, and the welding points of the first U-shaped wefts 11 and the second U-shaped wefts 12 with the warps 101 are located on the outside of the narrowing portion 20, and the welding points of the other U-shaped wefts 102 with the warps 101 are located on the inside of the warps 101.

[0080] like Figure 2 , Figure 3 , Fig.11 As shown, the first U-shaped weft wire 11 and the second U-shaped weft wire 12 are metal square wires with square cross sections. The side of the first U-shaped weft wire 11 facing the second U-shaped weft wire 11 is the front limiting plane f1, and the side of the second U-shaped weft wire 12 facing the first U-shaped weft wire 11 is the rear limiting plane f2. The inner side planes f3 and f4 of the first U-shaped weft wire 11 and the second U-shaped weft wire 12 are spot welded to the outer side of the narrowing portion 20.

[0081] The front limiting plane f1, the rear limiting plane f2, and the plurality of narrowing portions 20 form a clamping groove 30, so the clamping groove 30 also has a U-shaped structure similar to the U-shaped weft 102. Figures 4 to 9 As shown, when the wire mesh bridge frames 100 for carrying cables are connected end to end, the clamping groove 30 located at the head end of the rear wire mesh bridge frame 100 for carrying cables is used to clamp the third U-shaped weft line 13 at the end of the front wire mesh bridge frame 100 for carrying cables. At this time, the front limiting plane f1 and the rear limiting plane f2 limit the third U-shaped weft line 12 front to back, thereby connecting and fixing the two adjacent wire mesh bridge frames 100 for carrying cables end to end.

[0082] like Figure 1 and Fig.10 As shown, in this embodiment, each U-shaped weft 102 is a metal square wire with a square cross section, so that not only the first U-shaped weft 11 and the second U-shaped weft 12 are metal square wires with a square cross section, but also the third U-shaped weft 13 is a metal square wire with a square cross section. Thus, two metal square wires with a square cross section clamp a metal square wire with a square cross section, and the clamping and limiting structure formed thereby has a large clamping contact area, and the clamping is more secure and not easy to loosen.

[0083] In other embodiments, only the first U-shaped weft wire 11, the second U-shaped weft wire 12 and the third U-shaped weft wire 13 may be metal square wires with square cross sections, and the other U-shaped weft wires 102 may be metal round wires with round cross sections. This has the advantage of saving consumables of metal wires, but has the disadvantage of requiring the production of two types of metal wires with cross sections, which places additional requirements on production line equipment and production processes.

[0084] like Figure 2 and Figure 3 As shown, the warp 101 has a hook portion 21 at the clamping end 10, which is bent inward to form a narrowing portion 20. The hook portion 21 includes a first inclined portion 22 inclined from the outside to the inside, a parallel spot welding portion 23 and a second inclined portion 23 inclined from the inside to the outside, so that the warp 101 starts to bend inward from the first inclined portion 22 at the clamping end 10, the parallel spot welding portion 23 is roughly parallel to the body of the warp 101, and the second inclined portion 23 is bent outward. The hook portions 21 of multiple warp wires 101 make the head end of the wire mesh bridge 100 for carrying cables present an inwardly narrowed shape.

[0085] The inner planes f3 and f4 of the first U-shaped latitude line 11 and the second U-shaped latitude line 12 are spot welded to the outer side of the parallel spot welding portion 23. Since the parallel spot welding portion 23 and the main body of the warp line 101 are roughly parallel in this embodiment, the inner planes f3 and f4 of the first U-shaped latitude line 11 and the second U-shaped latitude line 12 are parallel to the main body of the warp line 101, and the front limiting plane f1 and the rear limiting plane f2 are perpendicular to the direction in which the main body of the warp line 101 is located, that is, they are perpendicular to the extension direction of the metal wire mesh bridge 100 used to carry cables, thereby achieving a more balanced and stable front and rear limiting effect, and the mesh bridge system 200 after being connected end to end is more solid and straight.

[0086] Further, the distance between the front limiting plane f1 and the rear limiting plane f2 is smaller than the size of the third U-shaped weft line 13, so as to form an interference fit between the first U-shaped weft line 11, the third U-shaped weft line 13, and the second U-shaped weft line 12. In the present embodiment, the distance between the front limiting plane f1 and the rear limiting plane f2 is smaller than the side length of the cross section of the third U-shaped weft line 13, so as to form an interference fit between the first U-shaped weft line 11, the third U-shaped weft line 13, and the second U-shaped weft line 12.

[0087] Embodiment 2:

[0088] like Figures 12 to 17 Shown is a wire mesh bridge 100' for carrying cables provided in this embodiment, and a mesh bridge system 200' formed by connecting the wire mesh bridge 100' for carrying cables provided in this embodiment front to back end to end.

[0089] Likewise, if Fig.12 and Fig.17As shown, a wire mesh bridge 100' for carrying cables is formed into a mesh shape by connecting a plurality of warps 101' and a plurality of U-shaped wefts 102' by a spot welding process. The head end of the wire mesh bridge 100' for carrying cables is a clamping end 10', and the warps 101' are bent inwardly at the clamping end 10' to form a narrowing portion 20'. The clamping end 10' includes two first U-shaped wefts 11' and second U-shaped wefts 12' close to each other, and the welding points of the first U-shaped wefts 11' and the second U-shaped wefts 12' with the warps 101' are located on the outside of the narrowing portion 20', and the welding points of the other U-shaped wefts 102' with the warps 101' are located on the inside of the warps 101'.

[0090] like Figures 13 to 16 As shown, in this embodiment, each U-shaped weft 102' is a metal round wire with a circular cross section, so the third U-shaped weft 13' is also a metal round wire with a circular cross section. Thus, two metal square wires with a square cross section clamp a metal round wire with a circular cross section. Compared with the first embodiment, although the clamping contact area of ​​the clamping and limiting structure is reduced, the clamping force of the two metal square wires is sufficient to ensure that the two adjacent metal wire mesh bridges 100' for carrying cables are reliably connected and fixed, and the consumables of the metal wire are saved. The mechanical strength of the metal round wire is slightly higher than that of the metal square wire, and the deformation ability is also better than that of the metal square wire. From a comprehensive evaluation, the first embodiment and the present embodiment each have their own advantages and disadvantages, and can be selected according to actual conditions.

[0091] In other embodiments, only the third U-shaped weft wire 13 ′ may be a metal round wire with a circular cross section, and the other U-shaped weft wires 102 ′ may be metal square wires with a square cross section.

[0092] Therefore, in the present embodiment, the distance between the front limiting plane f1' and the rear limiting plane f2' is smaller than the diameter of the third U-shaped weft wire 13', so as to form an interference fit between the first U-shaped weft wire 11', the third U-shaped weft wire 13' and the second U-shaped weft wire 12'. Since the third U-shaped weft wire 13' is a metal round wire, compared with the first embodiment, the present embodiment will be smoother during the connection and assembly operation, and the assembly efficiency is improved.

[0093] The other structures of the wire mesh bridge 100 ′ and the mesh bridge system 200 ′ for carrying cables provided in this embodiment are the same as those in the first embodiment, and will not be repeated here.

[0094] Embodiment three:

[0095] The wire mesh bridge for carrying cables provided in the first and second embodiments has only a clamping end at the head end and a first U-shaped weft at the tail end. The mesh bridge system is formed by connecting a number of wire mesh bridges for carrying cables with the same structure end to end.

[0096] Different from Example 1 and Example 2, both ends of the metal wire mesh bridge for carrying cables provided in this embodiment are clamping ends, and the specific structure of the clamping ends is the same as that of Example 1 and Example 2. This metal wire mesh bridge for carrying cables needs to be interconnected and fixed with other metal wire mesh bridges for carrying cables that have a third U-shaped weft at at least one end. For example, a clamping and limiting structure is formed with the third U-shaped weft at the end of the metal wire mesh bridge for carrying cables provided in Example 1 or Example 2, so as to be connected end to end; for another example, a clamping and limiting structure is formed with the third U-shaped weft at any end of an ordinary metal wire mesh bridge for carrying cables that does not have clamping ends at both ends, so as to be connected end to end.

[0097] Therefore, in this embodiment, a metal wire mesh bridge with clamping ends at both ends for carrying cables, a metal wire mesh bridge with a clamping end only at the first end for carrying cables, and an ordinary metal wire mesh bridge with non-clamping ends at both ends for carrying cables can be freely combined to form a mesh bridge system by connecting them end to end.

[0098] The grid bridge system formed in this way at least follows the following rules: two adjacent wire grid bridges for carrying cables are connected end to end through a clamping and limiting structure. The clamping and limiting structure includes a clamping end and a non-clamping end, the non-clamping end includes a third U-shaped weft, the structure of the clamping end is the same as that of the first and second embodiments, the first U-shaped weft and the second U-shaped weft of the clamping end are metal square wires with square cross-sections, clamping a third U-shaped weft of the non-clamping end, and the front limiting plane and the rear limiting plane are used to limit the third U-shaped weft front and back.

[0099] Therefore, this embodiment provides an implementation method with higher degree of freedom, higher adaptability, and can be flexibly changed according to the specific environment of the actual installation application scenario. However, compared with the first and second embodiments, the standardization and homogeneity of the wire mesh bridge used to carry the cables are reduced, and the support of multiple production lines is required.

[0100] The other structures of the wire mesh bridge and the mesh bridge system for carrying cables provided in this embodiment are the same as those in the first or second embodiment, and will not be repeated here.

[0101] It can be seen that the metal wire mesh bridge for carrying cables provided by the utility model clamps the third U-shaped weft by making the first U-shaped weft and the second U-shaped weft at the clamping end into metal square wires with square cross-sections, and restricts the third U-shaped weft front and back with the front limiting plane of the first U-shaped weft and the rear limiting plane of the second U-shaped weft, so as to connect and fix two adjacent metal wire mesh bridges for carrying cables end to end. This clamping and limiting structure does not need to be processed on two U-shaped wefts to form an arched structure as in the prior art, thereby overcoming the technical problem in the prior art that the arching and bending process produces local cracks that reduce the structural strength of the U-shaped weft, and ensures the structural strength and reliability of the end-to-end self-connection of the metal wire mesh bridge with a simple structure and simple processing technology.

[0102] The wire mesh bridge for carrying cables is connected end to end, and the mesh bridge is not only smooth inside and outside, but also has little friction effect on the cables it carries. The connection is firm and reliable, and it is not easy to cause looseness and collapse due to linkage effect. Furthermore, since there is no need to process the arched bending structure, the wire mesh bridge for carrying cables provided by the utility model can greatly save consumables, and the cost reduction in large-scale production is particularly significant.

[0103] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0104] The above is an introduction to the wire mesh bridge and mesh bridge system for carrying cables provided by the utility model. This article uses specific examples to illustrate the principle and implementation of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
