Embodiment 1

[0032] As shown in Figure 1 , 2 , the application provides a ladder type bridge, which comprises a bridge base plate 100, a cross arm 200 and a first connecting plate 300. The bridge base plate 100 comprises two vertical plates 110, and a plurality of cross arms 200 are arranged between the two vertical plates 110. One end of the vertical plate 110 extends in a direction perpendicular to the vertical plate 110 to form a first extension 111. The side of the first extension 111 away from the vertical plate 110 extends in a direction perpendicular to the first extension 111 to form the first connecting plate 300.

[0033] In this embodiment, the bridge base plate 100 is a basic component of the ladder type bridge. The vertical plate 110 in the bridge base plate 100 mainly plays a role of enclosing. The cross arm 200 is a component that spans between the two vertical plates 110. A plurality of cross arms 200 are arranged at equal intervals and in parallel between the vertical plates. The cross arm 200 is used to support the cable and prevent the cable from winding or falling. The first extension 111 is a part extending from the vertical plate 110, which provides a basic structure for the formation of the first connecting plate 300. The first connecting plate 300 at the end of the ladder type bridge is connected to the vertical plate 110 through the first extension 111, and the first connecting plate 300 and the first extension 111 are in L shape. In this embodiment, the two first extensions 111 extend in directions away from each other, so that the distance between the two first connecting plates 300 is greater than the distance between the two vertical plates 110, so as to facilitate the insertion of the vertical plate 110 of another ladder type bridge between the two first connecting plates 300, thereby facilitating the connection of the two ladder type bridges. In another embodiment, the two first extensions 111 extend in directions close to each other, so that the distance between the two first connecting plates 300 is less than the distance between the two vertical plates 110, so as to facilitate the insertion of the two first connecting plates 300 between the two vertical plates 110 of another ladder type bridge.

[0034] The width of the first extension 111 is substantially equal to the thickness of the vertical plate 110, which facilitates the alignment and connection of the two ladder type bridges.

[0035] In summary, the first connecting plate 300 provides a standardized interface for the connection of the ladder type bridge, facilitates the splicing and assembly of multiple bridges, greatly improves the efficiency of the installation of the ladder type bridge, and reduces the construction difficulty and cost.

[0036] As shown in Figure 1 , the bridge base plate 100 further comprises a bearing plate 120, which is connected perpendicularly to the vertical plate 110.

[0037] In the embodiment, the bearing plate 120 in the bridge base plate 100 is used to bear the cross arm 200, the vertical connection of the vertical plate 110 and the bearing plate 120, and the fixing of the cross arm 200 on the bearing plate 120 through the welding process, which guarantees the basic shape and stability of the ladder type bridge. In the embodiment, two bearing plates 120 are provided, and the two bearing plates 120 are in a strip shape, and the two bearing plates 120 are vertically connected with the two vertical plates 110, and in another specific embodiment, the bearing plate 120 is a rectangular plate, and the two vertical plates 110 are connected with the two sides of the bearing plate 120.

[0038] As shown in Figure 2 , the first connecting plate 300 is provided with a plurality of first fixing holes 310, and the end of the vertical plate 110 away from the first connecting plate 300 is provided with a plurality of second fixing holes 112. The first fixing hole 310 is matched with the second fixing hole 112, and when two ladder type bridges are connected together, the screw can be fixedly connected through the first fixing hole 310 and the second fixing hole 112.

[0039] In the embodiment, two first fixing holes 310 are provided in the middle of the first connecting plate 300, and the first fixing hole 310 penetrates the first connecting plate 300. The second fixing hole 112 is located at the end of the vertical plate 110 opposite to the first connecting plate 300, and the shape and number of the second fixing hole 112 are matched with the first fixing hole 310. The second fixing hole 112 is matched with the first fixing hole 310, and when two ladder type bridges are connected, the screw is used to pass through the first fixing hole 310 and the second fixing hole 112 to realize the fastening connection between the ladder type bridges.

[0040] As described above, through the matching design of the first fixing hole 310 and the second fixing hole 112, the connection mode of the ladder type bridge is greatly simplified. In the large-scale ladder type bridge laying engineering, the construction personnel can quickly connect multiple bridges into a complete wiring channel. Compared with the traditional connection mode through welding, the complex welding steps are not needed, and the installation time and labor cost are saved.

[0041] As shown in Figure 2 , the side of the vertical plate 110 away from the bearing plate 120 is bent inward to form a curled edge 113.

[0042] In the embodiment, the curled edge 113 is a structure formed by bending the edge of the vertical plate 110 inward, which can enhance the edge strength of the vertical plate 110 and prevent the edge of the vertical plate 110 from being deformed or damaged when subjected to external force impact or extrusion. At the same time, the curled edge 113 can also play a certain protection role to avoid the operator being cut by the edge of the vertical plate 110 during installation or use.

[0043] AsFigure 1 As shown in the figure, the distance between two adjacent cross arms 200 is greater than or equal to 200 mm and less than or equal to 300 mm.

[0044] In the embodiment, the parallel and spaced several cross arms 200, the distance between adjacent cross arms 200 refers to the length direction of the ladder type bridge, the interval distance between the midpoints of two adjacent cross arms 200, the distance between two adjacent cross arms 200 is greater than or equal to 200 mm and less than or equal to 300 mm, which is determined by comprehensively considering the carrying capacity of the bridge, the heat dissipation requirement of the cable and the rationality of wiring and other factors. Specific embodiment 2

[0046] As shown in the figure, Figure 3 , 4 Different from the above specific embodiment 1, the second extension 121 is formed by extending the end of the bearing plate 120 close to the first connecting plate 300 in the direction perpendicular to the bearing plate 120, and the second connecting plate 400 is formed by extending the side away from the bearing plate 120 of the second extension 121 in the direction perpendicular to the second extension 121.

[0047] In the embodiment, two bearing plates 120 are provided, and the two bearing plates 120 are in strip shape, and the two bearing plates 120 are respectively connected with the two vertical plates 110 perpendicularly, and in another specific embodiment, the bearing plate 120 is a rectangular plate, and the two vertical plates 110 are connected with the two sides of the bearing plate 120. The second extension 121 is the part extended from the bearing plate 120, and the second extension 121 is located on the two sides of the bearing plate 120 close to the vertical plate 110, and the second extension 121 is similar to the first extension 111, and the second extension 121 provides a basis for the formation of the second connecting plate 400. In the embodiment, the second extension 121 extends away from the curled edge 113, and in another specific embodiment, the second extension 121 can also extend towards the curled edge 113. The second connecting plate 400 cooperates with the first connecting plate 300 to reinforce and expand the connection part of the bridge from different directions, and the structure extended from the bearing plate 120 further enriches the connection mode of the ladder type bridge and the stability of the connection part structure.

[0048] The thickness of the second extension 121 is substantially equal to the thickness of the bearing plate 120, which is convenient for the alignment connection of the two ladder type bridges.

[0049] As described above, when splicing with the adjacent ladder type bridge, the second connecting plate 400 provides an additional support surface, making the splicing operation more convenient.

[0050] As shown in the figure, Figure 4 The first connecting plate 300 and the second connecting plate 400 are arc-shapedly connected.

[0051] In this embodiment, the arc-shaped connection between the first connecting plate 300 and the second connecting plate 400 means that the two are naturally transitioned at the connection site without obvious protrusions or depressions. This arc-shaped connection makes the ladder-type bridge more neat and beautiful in appearance, and at the same time, since the first connecting plate 300 and the second connecting plate 400 are connected together, the structural stability of each of the first connecting plate 300 and the second connecting plate 400 is guaranteed. Specific embodiment 3

[0053] As shown in Figure 5 , 6 , unlike the above specific embodiment 2, the ladder-type bridge further includes a third connecting plate 500, which connects the two second connecting plates 400.

[0054] In this embodiment, the third connecting plate 500 is a component that connects the two second connecting plates 400, which further connects the two second connecting plates 400 into one whole. Through the connection of the third connecting plate 500, the structure of the second connecting plate 400 is more stable and can withstand greater lateral tension and pressure, preventing the second connecting plate 400 from being laterally deformed or twisted when subjected to external forces. At the same time, since the surface of the third connecting plate 500 is in the same plane as the surface of the second connecting plate 400, the third connecting plate 500 and the second connecting plate 400 together provide additional support surface for the ladder-type bridge, facilitating the connection of the two ladder-type bridges.

[0055] As shown in Figure 6 , the first connecting plate 300, the second connecting plate 400, and the third connecting plate 500 are integrally formed.

[0056] In this embodiment, integrally formed means that the first connecting plate 300, the second connecting plate 400, and the third connecting plate 500 are formed into an indivisible whole structure through a specific manufacturing process, such as stamping, casting, etc. This manufacturing method avoids the problems of connection gaps and welding defects that may exist in traditional connection methods, ensuring the connection strength between the first connecting plate 300, the second connecting plate 400, and the third connecting plate 500 and the integrity of the overall structure.

[0057] In summary, the integrally formed first connecting plate 300, the second connecting plate 400, and the third connecting plate 500 significantly improve the quality and reliability of the connection site of the ladder-type bridge, so that the first connecting plate 300, the second connecting plate 400, and the third connecting plate 500 can better withstand various complex stresses, whether it is tensile, bending, or torsional stress, which can be evenly distributed on the entire integrally formed structure. Specific embodiment 4

[0059] As shown in Figure 7 , 8As shown, different from the specific embodiment 1, the carrier plate 120 is in one piece, the carrier plate 120 extends along the direction perpendicular to the carrier plate 120 to form a third extension 122, and the third extension 122 extends along the direction perpendicular to the third extension 122 from the side of the carrier plate 120 to form a fourth connecting plate 600.

[0060] In the embodiment, the carrier plate 120 is a rectangular plate, the two vertical plates 110 are connected to the two sides of the carrier plate 120, the third extension 122 is the part of the carrier plate 120 extending along the direction perpendicular to the carrier plate 120 from the middle of the end of the carrier plate 120 close to the first connecting plate 300, and the extending direction of the third extension 122 has two kinds, in the embodiment, the third extension 122 extends away from the curled edge 113, and in another specific embodiment, the third extension 122 can extend towards the curled edge 113. The third extension 122 provides a basis for the formation of the fourth connecting plate 600, and the fourth connecting plate 600 is formed by the third extension 122, and the two sides of the fourth connecting plate 600 have gaps with the two first connecting plates 300. The fourth connecting plate 600 provides an additional support surface for the ladder type bridge to facilitate the splicing operation of the two ladder type bridges, and the thickness of the third extension 122 is substantially equal to the thickness of the carrier plate 120 to facilitate the alignment of the two ladder type bridges to be spliced. Figure 8

[0061] In another specific embodiment, the two sides of the fourth connecting plate 600 are connected with the two first connecting plates 300 respectively, so that the first connecting plate 300 and the fourth connecting plate 600 form an integral structure to strengthen the structural stability of the first connecting plate 300 and the fourth connecting plate 600.

[0062] In summary, the fourth connecting plate 600 cooperates with the first connecting plate 300 to reinforce and expand the connection part of the bridge from different directions, and the structure extending from the carrier plate 120 further enriches the connection mode of the ladder type bridge and the stability of the structure of the connection part.

[0063] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent flow transformation using the content of the specification and drawings of the present application, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.​
