Specific Implementation Example 1

[0031] like Figure 1 , 2 As shown, this application provides a reinforced ladder-type cable tray. The reinforced ladder-type cable tray includes a cable tray base plate 100, crossbeams 200, and reinforcing ribs 700. The cable tray base plate includes an upright plate 110 and a support plate 120. There are two upright plates 110, and several crossbeams 200 are disposed between the two upright plates 110. The support plate 120 is vertically connected to the upright plates 110 and is used to support the crossbeams 200. Several reinforcing ribs 700 are provided at the connection between the support plate 120 and the upright plate 110. The reinforcing ribs 700 are connected to the upright plate 110 and the support plate 120.

[0032] In this embodiment, the cable tray base plate 100 is the basic component constituting the reinforced ladder-type cable tray. The upright plates 110 in the cable tray base plate 100 mainly serve as enclosures, while the crossarms 200 are components that span between two upright plates 110. Several crossarms 200 are evenly spaced and parallel between the upright plates. The crossarms 200 are used to support cables and prevent them from tangling or slipping. The support plate 120 in the cable tray base plate 100 is used to support the crossarms 200. The crossarms 200 are fixed to the support plate 120 by vertical connection between the upright plates 110 and the support plate 120, and by welding or screw fixing, ensuring the basic shape and stability of the reinforced ladder-type cable tray. In this embodiment, there are two support plates 120, and the two support plates 120 are elongated. The two support plates 120 are vertically connected to the two upright plates 110 respectively. In another specific embodiment, the support plate 120 is a rectangular plate, and the upright plates 110 on both sides are connected to the two sides of the support plate 120. The reinforcing rib 700 is roughly rectangular in shape. It is located at the connection between the vertical plate 110 and the bearing plate 120, and at the midpoint of the line connecting two adjacent crossbeams 200. Several reinforcing ribs 700 are evenly spaced. The reinforcing rib 700, the vertical plate 110 and the bearing plate 120 are integrally formed. The setting of the reinforcing rib 700 ensures the connection strength and structural stability between the vertical plate 110 and the bearing plate.

[0033] In summary, by providing reinforcing ribs 700 at the connection between the upright plate 110 and the bearing plate 120, the connection strength and structural stability between the upright plate 110 and the bearing plate 120 are enhanced, making the connection between the upright plate and the bearing plate of the reinforced ladder cable tray in this application less prone to deformation, and able to meet the increasingly complex electrical installation requirements.

[0034] like Figure 1 As shown, a number of spaced-apart ribs 800 are provided on the upright plate 110.

[0035] In this embodiment, both upright plates 110 are provided with a plurality of protruding ribs 800. These protruding ribs 800 are evenly spaced and arranged in a straight line. Each protruding rib 800 is a raised structure on the upright plate 110, and its shape is not limited. In this embodiment, the protruding rib 800 protrudes from the upright plate 110 towards the support plate 120. In another specific embodiment, the protruding rib 800 protrudes from the upright plate 110 away from the support plate 120. The protruding rib 800 structure on the upright plate 110 can enhance the stability of the upright plate 100 and effectively prevent the upright plate 110 from deforming under external forces.

[0036] like Figure 2 As shown, one end of the upright plate 110 extends in a direction perpendicular to the upright plate 110 to form a first extension 111, and the side of the first extension 111 away from the upright plate 110 extends in a direction perpendicular to the first extension 111 to form a first connecting plate 300.

[0037] In this embodiment, the first extension 111 extends from the upright plate 110, providing a basic structure for the formation of the first connecting plate 300. The first connecting plate 300 at the end of the reinforced ladder cable tray is connected to the upright plate 110 via the first extension 111, and the first connecting plate 300 and the first extension 111 are L-shaped. In this embodiment, the two first extensions 111 extend in a direction away from each other, such that the distance between the two first connecting plates 300 is greater than the distance between the two upright plates 110, so that the upright plate 110 of another reinforced ladder cable tray can be inserted between the two first connecting plates 300, thereby facilitating the connection of the two reinforced ladder cable trays. In another specific embodiment, the two first extensions 111 extend in a direction close to each other, such that the distance between the two first connecting plates 300 is less than the distance between the two upright plates 110, so that the two first connecting plates 300 can be inserted between the two upright plates 110 of another reinforced ladder cable tray.

[0038] The width of the first extension 111 is approximately equal to the thickness of the upright plate 110, which facilitates the alignment and connection of the two reinforced ladder-type cable trays.

[0039] In summary, the first connecting plate 300 provides a standardized interface for connecting reinforced ladder cable trays, facilitating the splicing and assembly of multiple cable trays, greatly improving the efficiency of reinforced ladder cable tray installation, and reducing construction difficulty and cost.

[0040] like Figure 2 As shown, the first connecting plate 300 is provided with a plurality of first fixing through holes 310, and the end of the upright plate 110 away from the first connecting plate 300 is provided with a plurality of second fixing through holes 112. The first fixing through holes 310 and the second fixing through holes 112 are matched. When two reinforced ladder cable trays are connected together, screws can be used to fix the two reinforced ladder cable trays together through the first fixing through holes 310 and the second fixing through holes 112.

[0041] In this embodiment, two spaced-apart first fixing through holes 310 are provided in the middle of the first connecting plate 300. The first fixing through holes 310 penetrate through the first connecting plate 300. The second fixing through hole 112 is located on the upright plate 110 at the end opposite to the first connecting plate 300. The shape and number of the second fixing through holes 112 match the first fixing through holes 310. The function of the second fixing through holes 112 is to cooperate with the first fixing through holes 310. When two reinforced ladder cable trays are connected, screws are used to pass through the first fixing through holes 310 and the second fixing through holes 112 to achieve a tight connection between the reinforced ladder cable trays.

[0042] In summary, the matching design of the first fixing through hole 310 and the second fixing through hole 112 greatly simplifies the connection method of reinforced ladder cable trays. In large-scale reinforced ladder cable tray installation projects, construction workers can quickly connect multiple cable trays into a complete wiring channel. Compared with the traditional welding connection method, it eliminates the need for complex welding steps, saving installation time and labor costs.

[0043] like Figure 2 As shown, the side of the upright plate 110 away from the support plate 120 is bent inward to form a curled edge 113.

[0044] In this embodiment, the curled edge 113 is a structure formed by bending the edge of the upright plate 110 inward. It can enhance the edge strength of the upright plate 110 and prevent the edge of the upright plate 110 from deforming or being damaged when subjected to external impact or compression. At the same time, the curled edge 113 can also play a certain protective role, preventing operators from being scratched by the edge of the upright plate 110 during installation or use.

[0045] like Figure 1 As shown, the distance between two adjacent crossarms 200 is greater than or equal to 200 mm and less than or equal to 300 mm.

[0046] In this embodiment, several crossarms 200 are arranged in parallel intervals. The distance between adjacent crossarms 200 refers to the interval between the midpoints of two adjacent crossarms 200 along the length direction of the reinforced ladder cable tray. The setting of the distance between two adjacent crossarms 200 being greater than or equal to 200 mm and less than or equal to 300 mm is determined after comprehensively considering factors such as the load-bearing capacity of the cable tray, the heat dissipation requirements of the cables, and the rationality of the wiring. Specific Implementation Example 2

[0048] like Figure 3 , 4 As shown, unlike the specific embodiment 1 above, the end of the support plate 120 near the first connecting plate 300 extends in a direction perpendicular to the support plate 120 to form a second extension 121, and the side of the second extension 121 away from the support plate 120 extends in a direction perpendicular to the second extension 121 to form a second connecting plate 400.

[0049] In this embodiment, two support plates 120 are provided, and the two support plates 120 are elongated. The two support plates 120 are perpendicularly connected to the two upright plates 110 respectively. In another specific embodiment, the support plate 120 is a rectangular plate, and the upright plates 110 on both sides are connected to the two sides of the support plate 120. The second extension 121 is the part extending from the support plate 120. The second extension 121 is located on both sides of the support plate 120 near the upright plates 110. The second extension 121 is similar to the first extension 111. The second extension 121 provides the basis for the formation of the second connecting plate 400. In this embodiment, the second extension 121 extends away from the curled edge 113. In another specific embodiment, the second extension 121 may 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 parts of the cable tray from different directions. This structure extending from the support plate 120 further enriches the connection method of the reinforced ladder cable tray and the stability of the connection part structure.

[0050] The thickness of the second extension 121 is approximately equal to the thickness of the bearing plate 120, which facilitates the alignment and connection of the two reinforced ladder-type cable trays.

[0051] In summary, when splicing with adjacent reinforced ladder cable trays, the second connecting plate 400 provides an additional support surface, making the splicing operation more convenient.

[0052] like Figure 4 As shown, the first connecting plate 300 and the second connecting plate 400 are connected in an arc shape.

[0053] In this embodiment, the arc-shaped connection between the first connecting plate 300 and the second connecting plate 400 means that the transition between the two at the connection point is natural, without obvious protrusions or depressions. This arc-shaped connection method makes the reinforced ladder cable tray more neat and aesthetically pleasing in appearance. At the same time, since the first connecting plate 300 and the second connecting plate 400 are connected together, the structural stability of the first connecting plate 300 and the second connecting plate 400 is guaranteed. Specific Implementation Example 3

[0055] like Figure 5 , 6 As shown, unlike the above-described specific embodiment 2, the reinforced ladder cable tray also includes a third connecting plate 500, which connects the second connecting plates 400 on both sides.

[0056] In this embodiment, the third connecting plate 500 is a component that connects the two second connecting plates 400 on both sides. It further connects the two second connecting plates 400 into a whole. Through the connection of the third connecting plate 500, the structure of the second connecting plates 400 becomes more stable, capable of withstanding greater lateral tensile and compressive forces, and preventing the second connecting plates 400 from undergoing lateral deformation or torsion when subjected to external forces. At the same time, since the surface of the third connecting plate 500 is on 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 an additional support surface for the reinforced ladder cable tray, facilitating the connection of the two reinforced ladder cable trays.

[0057] like Figure 6 As shown, the first connecting plate 300, the second connecting plate 400 and the third connecting plate 500 are integrally formed.

[0058] In this embodiment, integral molding means that the first connecting plate 300, the second connecting plate 400, and the third connecting plate 500 are formed into an inseparable integral structure through specific manufacturing processes, such as stamping and casting. This manufacturing method avoids problems such as connection gaps and welding defects that may exist in traditional connection methods, and ensures 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.

[0059] In summary, the integrally formed first connecting plate 300, second connecting plate 400 and third connecting plate 500 significantly improve the quality and reliability of the connection parts of the reinforced ladder cable tray, enabling the first connecting plate 300, second connecting plate 400 and third connecting plate 500 to better withstand various complex stresses. Whether it is tensile, bending or torsional stress, it can be evenly distributed on the entire integrally formed structure. Specific Implementation Example 4

[0061] like Figure 7 ,8 As shown, unlike the above specific embodiment 1, the support plate 120 is integral, and the support plate 120 extends in a direction perpendicular to the support plate 120 to form a third extension 122. The side of the third extension 122 away from the support plate 120 extends in a direction perpendicular to the third extension 122 to form a fourth connecting plate 600.

[0062] In this embodiment, the support plate 120 is a rectangular plate, and two upright plates 110 are perpendicularly connected to both sides of the support plate 120. The third extension 122 is the portion of the support plate 120 extending from the middle of the end near the first connecting plate 300 along a direction perpendicular to the support plate 120. The third extension 122 has two directions of extension. In this embodiment, the third extension 122 extends away from the curled edge 113. In another specific embodiment, the third extension 122 can extend towards the curled edge 113. The third extension 122 provides the basis for the formation of the fourth connecting plate 600, referring to... Figure 8 As shown, the fourth connecting plate 600 extends from the third extension 122, and there are gaps between the two sides of the fourth connecting plate 600 and the two first connecting plates 300. The fourth connecting plate 600 provides an additional support surface for the ladder-type cable trays to facilitate splicing operations between the two ladder-type cable trays, and the thickness of the third extension 122 is approximately equal to the thickness of the bearing plate 120 to facilitate the alignment of the two ladder-type cable trays to be spliced.

[0063] In another specific embodiment, the two sides of the fourth connecting plate 600 are respectively connected to the two first connecting plates 300, so that the first connecting plate 300 and the fourth connecting plate 600 form an integral structure, so as to enhance the structural stability of the first connecting plate 300 and the fourth connecting plate 600.

[0064] In summary, the fourth connecting plate 600 and the first connecting plate 300 work together to reinforce and expand the connection parts of the cable tray from different directions. This structure extending from the bearing plate 120 further enriches the connection methods of the ladder cable tray and the stability of the connection parts.

[0065] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
