Detailed implementation manners

[0035] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0036] As Figures 1-9 shown, an embodiment of the present invention provides a high-strength anti-corrosion aluminum alloy bridge, including: a U-shaped groove body, a cover plate 5, and a mounting bracket 3. The U-shaped groove body is composed of a bottom plate 1 and two side plates 2. The cover plate 5 is arranged at the opening of the U-shaped groove body. The side of the bottom plate 1 away from the cover plate 5 is densely distributed with honeycomb-shaped blind holes 4, and the side of the bottom plate 1 close to the cover plate 5 is provided with reinforcing ribs.

[0037] The working principle and beneficial effects of the above embodiment are as follows:

[0038] When installing the bridge, first install the mounting bracket 3, then install the U-shaped groove body on the mounting bracket 3, arrange the cables, and finally cover the cover plate 5. The honeycomb-shaped blind holes can improve the structural strength of the bottom plate 1. As the weight of the cables increases, the bottom plate 1 will not be bent and deformed after long-term use. At the same time, the reinforcing ribs can further improve the structural strength of the bottom plate 1. The blind holes are more conducive to the heat dissipation of the bottom plate 1. After the cables are energized and heated, the honeycomb-shaped blind holes 4 can dissipate heat, avoiding the aging of the cables caused by long-term use and heat generation.

[0039] In one embodiment, the cross-section of the bottom plate 1 is an isosceles triangle structure.

[0040] The working principle and beneficial effects of the above embodiment are as follows:

[0041] The cross-section of the bottom plate 1 is an isosceles triangle structure. When arranging cables, through the bottom plate 1 with an isosceles triangle structure, the cables can be made to approach both sides of the bottom plate 1. The cable distribution on the bottom plate 1 close to both sides can make the force on the bottom plate 1 tend to be close to the position of the side plate 2, further improving the load-bearing capacity of the bottom plate 1.

[0042] In one embodiment, multiple groups of the reinforcing ribs are provided, and the multiple reinforcing ribs are arranged at intervals on the surface of the bottom plate 1.

[0043] The working principle and beneficial effects of the above embodiment are as follows:

[0044] The reinforcing ribs can further improve the structural strength of the bottom plate 1, and the reinforcing ribs arranged at intervals can achieve the effect of cable separation, avoiding multi-strand cables.

[0045] In one embodiment, the reinforcing ribs include a first rib plate 6, a second rib plate 7, and an auxiliary rib plate 8. The first rib plate 6 and the second rib plate 7 are arranged at intervals at both ends of the surface of the bottom plate 1, and each of the first rib plates 6 and the second rib plates 7 is arranged in a staggered manner. The auxiliary rib plate 8 is arranged on the surface of the bottom plate 1, and the auxiliary rib plate 8 is respectively in the same straight line as the first rib plate 6 and the second rib plate 7.

[0046] The working principle and beneficial effects of the above embodiment are as follows:

[0047] The first rib plate 6 and the second rib plate 7 are arranged in a staggered manner, so that when forming a partition plate on the bottom plate 1, material can be saved, and the material consumption can be reduced while ensuring the structural strength;

[0048] The auxiliary rib plate 8 is in the same straight line as the first rib plate 6 and the second rib plate 7, so that the first rib plate 6, the auxiliary rib plate 8, the second rib plate 7, and the auxiliary rib plate 8 form a partition plate to limit the cables in the cable tray.

[0049] In one embodiment, the mounting bracket 3 includes a mounting rod assembly 9 and a clamping assembly. The mounting rod assembly 9 is used to hoist the cable tray on a building, and the clamping assembly is installed on the mounting rod assembly 9. The clamping assembly is used to clamp the cable tray on the mounting rod assembly 9.

[0050] The working principle and beneficial effects of the above embodiment are as follows:

[0051] When installing the mounting bracket 3, first install the mounting rod assembly 9 on the building, then install the clamping assembly on the mounting rod assembly 9, and set the cable tray on the clamping assembly. The clamping assembly can reduce the installation time and improve the installation efficiency.

[0052] In one embodiment, the mounting rod assembly 9 includes a U-shaped mounting bracket 3 and a connecting plate 10. The connecting plate 10 is arranged at both ends of the opening of the U-shaped mounting bracket 3, and the connecting plate 10 is used for threaded connection to a building. The clamping assembly is arranged inside the opening of the U-shaped mounting bracket 3.

[0053] The working principle and beneficial effects of the above embodiment are as follows:

[0054] The opening of the U-shaped structure of the mounting rod faces the mounting surface, and the clamping assembly is installed inside the opening of the U-shaped structure.

[0055] In one embodiment, the clamping assembly includes a mounting plate installed inside the opening of the U-shaped mounting bracket 3. A first hinge rod 11 is arranged on the surface of the mounting plate. A first connecting rod 16 and a second connecting rod 15 are rotatably arranged on the outer wall of the first hinge rod 11 in the circumferential direction. The first hinge rod 11 is arranged at a position close to the middle between the first connecting rod 16 and the second connecting rod 15. One end of the first connecting rod 16 and the second connecting rod 15 are respectively provided with a third connecting rod 18 and a fourth connecting rod 17. The ends of the third connecting rod 18 and the fourth connecting rod 17 far from the first connecting rod 16 and the second connecting rod 15 are both hinged to a second hinge rod 12. The second hinge rod 12 is arranged on a pull rod 14. A bearing platform 13 is arranged at the end of the pull rod 14 far from the second hinge rod 12. Limiting components are arranged at the ends of the first connecting rod 16 and the second connecting rod 15 far from the third connecting rod 18 and the fourth connecting rod 17.

[0056] Both the first connecting rod 16 and the second connecting rod 15 are of an L-shaped structure. The limiting component includes a first vertical plate 19 and a second vertical plate 20. One end of the first vertical plate 19 is hinged at the corner of the L-shaped structure. One ends of the L-shaped structure far from the third connecting rod 18 and the fourth connecting rod 17 are respectively hinged to one end of the second vertical plate 20. A plurality of connecting rods 21 are further arranged between the first vertical plate 19 and the second vertical plate 20. Both ends of each connecting rod 21 are respectively hinged to the first vertical plate 19 and the second vertical plate 20. Each connecting rod 21 is arranged in parallel. Each connecting rod 21 is parallel to the end of the L-shaped structure close to the first vertical plate 19. The two second vertical plates 20 are used for clamping the bridge.

[0057] The working principle and beneficial effects of the above embodiment are as follows:

[0058] After the clamping component is installed, place one side of the bottom plate 1 of the cable bridge on the clamping component. At this time, the bottom plate 1 is placed on the bearing platform 13. Affected by gravity, the bearing platform 13 drives the pull rod 14 to move downward. One ends of the third connecting rod 18 and the fourth connecting rod 17 close to the pull rod 14 move downward. One ends of the first connecting rod 16 and the second connecting rod 15 close to the third connecting rod 18 and the fourth connecting rod 17 move downward. The first connecting rod 16 and the second connecting rod 15 swing around the first hinge rod 11. The ends of the first connecting rod 16 and the second connecting rod 15 away from the mounting plate approach each other, and at the same time drive the two first vertical plates 19 to approach each other. At the same time, the two second vertical plates 20 approach each other to clamp the side wall of the cable bridge. After the cable is laid in the cable bridge, the weight of the cable bridge increases, so that the bearing platform 13 receives a greater downward force, and the clamping of the side wall of the cable bridge by the second vertical plates 20 on both sides is tighter;

[0059] After the clamping component is installed, the second vertical plate 20 and the first vertical plate 19 move downward under the influence of gravity. At this time, the distance between the two second vertical plates 20 is the largest, making it more convenient to install the cable bridge and easier to set the cable bridge in the clamping component. At the same time, when disassembling and repairing, the clamping component can be opened as long as the cable bridge is lifted.

[0060] In one embodiment, it further includes an adapter. The adapter includes a fixing component and an adapter cable bridge 22. Both ends of the adapter cable bridge 22 are used to connect the U-shaped groove body. The fixing component is arranged at the connection between the adapter cable bridge 22 and the U-shaped groove body. The fixing component is arranged on the inner side of the deflection direction of the U-shaped groove body. The fixing component includes a first mounting plate 23 and a curved rod 24. Both ends of the first mounting plate 23 are provided with first mounting holes 25. The first mounting holes 25 are used for bolt threaded connection with the side wall of the U-shaped groove body. A first hinge plate 26 is arranged on the side of the first mounting plate 23 away from the U-shaped groove body. One end of the curved rod 24 is hinged to one side of the first hinge plate 26. One end of a first swing rod 27 is hinged to the other side of the first hinge plate 26. The other end of the first swing rod 27 is hinged at the corner of the L-shaped rod 28. One end of the L-shaped rod 28 is hinged to one end of the second hinge plate 29. The other end of the L-shaped rod 28 is respectively hinged to the middle section of the curved rod 24 and one end of a spring rod 30. The bending direction of the curved rod 24 faces the L-shaped rod 28. One end of a second swing rod 31 is hinged to the end of the curved rod 24 away from the first hinge plate 26. The other end of the second swing rod 31 is hinged to the end of the second hinge plate 29 away from the L-shaped rod 28. The end of the spring rod 30 away from the L-shaped rod 28 is connected to the end of the curved rod 24 away from the first hinge plate 26;

[0061] A second mounting plate 32 is arranged on the side of the second hinge plate 29 away from the curved rod 24. Both ends of the second mounting plate 32 are provided with second mounting holes 33. The second mounting holes 33 are used for bolt threaded connection with the side wall of the adapter cable bridge 22.

[0062] The working principle and beneficial effects of the above embodiments are as follows:

[0063] When it is necessary to change the routing direction of the cable tray, the adapter can be used to fix two cable trays portably. During use, the fixing component is installed on the side of the U-shaped trough body that needs to turn, close to the inner side of the turning direction. The first mounting piece 23 is installed on the side wall of the U-shaped trough body through bolts, and then the second mounting piece 32 is installed on the side wall of the adapter cable tray 22 through bolts. Similarly, for the other end of the adapter cable tray 22, another U-shaped trough body is fixed through the first mounting piece 23 and the second mounting piece 32. When it is necessary to adjust the angle between the adapter cable tray 22 and the U-shaped trough body, pulling one end of the adapter cable tray 22 can achieve the purpose of adjusting the angle. The adjustment is convenient and fast. Compared with the existing cable tray corners, it is not limited to a single fixed angle of ordinary corners, is flexible and changeable, improves the flexibility and portability during indoor and outdoor wiring, and is suitable for use in a variety of environments;

[0064] The settings of the first swing rod 27, the curved rod 24, and the L-shaped rod 28 ensure that when the angle between the second mounting piece 32 and the first mounting piece 23 changes, the adjacent ends of the second mounting piece 32 and the first mounting piece 23 always remain close to each other, preventing the distance between the adapter cable tray 22 and the U-shaped trough body from increasing when adjusting the angle;

[0065] The setting of the spring rod 30 provides a buffering effect when the cable tray is subjected to external forces, and always pulls the end of the L-shaped rod 28 close to the curved rod 24 towards the spring rod 30. The other end of the L-shaped rod 28 drives the second mounting piece 32 towards the first mounting piece 23, preventing the cable trays from being squeezed and bent when the traditional adapter corner connects two cable trays and encounters strong external forces.

[0066] In one embodiment, it further includes an adapter plate assembly. The adapter plate assembly includes a spring side plate 34 and a sector plate 35. The spring side plate 34 is slidably arranged on the side wall of the adapter cable tray 22. One end of the spring side plate 34 away from the adapter cable tray 22 is provided with a first strip-shaped block 36. The side wall of the U-shaped trough body is provided with a first card slot 37. The first strip-shaped block 36 is used to be clamped in the first card slot 37;

[0067] The top surface and bottom surface of the adapter cable tray 22, the surface of the cover plate 5, and the bottom surface of the U-shaped trough body are all provided with second strip-shaped blocks 38. Both sides of the sector plate 35 are provided with second card slots. The second strip-shaped blocks 38 are used to be clamped in the second card slots.

[0068] The working principle and beneficial effects of the above embodiments are as follows:

[0069] After the installation of the fixing component is completed, the first strip-shaped block 36 of the spring side plate 34 is clamped into the first clamping groove 37. When the adapter bridge 22 is pulled to adjust the included angle, the spring side plate 34 slides out from the side wall of the adapter bridge 22 to close the adapter bridge 22 and the side of the U-shaped groove body away from the fixing component. Subsequently, the sector plate 35 is cut, and after being cut to a suitable size, grooves are formed on both sides of the sector plate 35 to form second clamping grooves. Then, the second clamping grooves of the sector plate 35 are respectively clamped onto each second strip-shaped block 38, thereby closing the upper and lower surfaces between the U-shaped groove body and the adapter bridge 22;

[0070] Through the detachable adapter plate assembly, it is convenient to close the space between the adapter bridge 22 and the U-shaped groove body. At the same time, when the cables at the corner need to be adjusted in position, the cables can be adjusted by conveniently detaching the sector plate 35 or the spring side plate 34, which is convenient and efficient.

[0071] In one embodiment, a plurality of guiding devices are arranged at intervals at one end of the adapter bridge 22 close to the U-shaped groove body. Each guiding device corresponds to each reinforcing rib. The guiding device includes a bracket 39, a guiding wheel 40, a runner 41, and a guiding plate 42. The bracket 39 is of a U-shaped structure. One end of the guiding wheel 40 is rotatably arranged on the inner wall of the opening of the U-shaped structure of the bracket 39. The other end of the guiding wheel 40 is connected to one end of the runner 41. The side wall of the runner 41 is used to abut against the cable. The end of the runner 41 away from the guiding wheel 40 is connected to the guiding plate 42. A first guiding groove 43 is arranged on the outer circumferential wall of the guiding wheel 40. One end of a U-shaped rod 44 is slidably arranged in the first guiding groove 43. The middle section of the U-shaped rod 44 is slidably arranged at one end of the bracket 39 away from the guiding wheel 40. The U-shaped rod 44 passes through the side wall of the bracket 39 and is rotatably connected to one end of a U-shaped lever 45. One end of the U-shaped lever 45 close to the U-shaped rod 44 is slidably arranged on the inner wall of a guiding barrel 46. The outer circumferential wall of the guiding barrel 46 is rotatably connected to the side wall of one end of the bracket 39 away from the guiding wheel 40. An antenna 47 is arranged at the end of the guiding barrel 46 away from the U-shaped lever 45. The antenna 47 is slidably arranged in a second guiding groove 48. The second guiding groove 48 is arranged on the surface of the guiding plate 42. The first guiding groove 43 is used to drive the longitudinal movement of the U-shaped rod 44 when the guiding wheel 40 rotates. The second guiding groove 48 is used to drive the rotation of the guiding barrel 46 when the guiding plate 42 rotates. The guiding barrel 46 is used to drive the turning of the U-shaped lever 45;

[0072] The opening of the U-shaped lever 45 faces the runner 41, and a cable lifting rod 49 is arranged at the end of the U-shaped lever 45 away from the guiding barrel 46.

[0073] The working principle and beneficial effects of the above embodiment are as follows:

[0074] When making electrical connections to cables, it is often necessary to drag the cables to move within the cable tray to adjust the cable routing length. Since there are multiple corners in the cable tray, directly pulling hard may cause the cables to rub against the corners of the cable tray, resulting in damage to the insulating material on the cable surface. In severe cases, it may even lead to cable breakage and the cable tray shaking due to the huge tensile force. Therefore, it is very necessary to set up a guiding device in the cable tray;

[0075] When the cable is dragged, the movement of the cable drives the rotation of the runner 41, so that when the cable moves at the corner, the friction force is reduced through the runner 41 to protect the cable. Multiple cables are respectively arranged between the reinforcing ribs. The multiple guiding devices provided can prevent the cables from knotting at the corners after being separated, thus increasing the force required for cable dragging. When the runner 41 rotates, it drives the guiding wheel 40 and the guiding plate 42 to rotate. When the guiding wheel 40 rotates, the first guiding groove 43 on its surface drives the longitudinal movement of the U-shaped rod 44. The other end of the U-shaped rod 44 drives the longitudinal lifting or lowering of the U-shaped lever 45. When lifting, the cable lifting rod 49 at the other end of the U-shaped lever 45 lifts the cable. The cable lifting rod 49 is arranged at the bottom of the U-shaped groove body. When the cable is slightly lifted, dragging the cable can reduce the friction force between the cable and the bottom surface of the cable tray, thus further protecting the cable. The first guiding groove 43 can intermittently lift and lower the cable;

[0076] When the guiding plate 42 rotates, the antenna 47 slides in the second guiding groove 48, so that the second guiding groove 48 drives the rotation of the antenna 47, and then drives the rotation of the guiding barrel 46 through the antenna 47. A sliding groove can be arranged in the guiding barrel 46, and a slider is arranged on the outer wall of the U-shaped lever 45. The slider slides in the sliding groove to drive the rotation of the U-shaped lever 45. After the U-shaped lever 45 drives the cable to rise and then fall through the cable lifting rod 49, at this time, one end of the U-shaped lever 45 is at the surface position of the runner 41. The second guiding groove 48 drives the U-shaped lever 45 to rotate around the guiding barrel 46, so as to squeeze the cable on one side of the runner 41 towards the runner 41. A cable clamping groove is arranged on the surface of the guiding wheel 40, which can squeeze the subsequent cable entering the runner 41 into the clamping groove, thus preventing the subsequent cable from detaching from the runner 41 when passing through the runner 41.
