Cable trays are divided into different types according to the use environment and function, such as trough type, ladder type, tray type, etc., which are suitable for various cables such as power, communication, and control. It not only improves the service life of cables, but also ensures the safety and neatness of the wiring system.

[0003] In the prior art, some cable trays are generally in the shape of a rectangular block composed of multiple alloy plates. The inner cavity space for accommodating cables is fixed, but the number of cables actually laid is small. Most of the space in the inner cavity may not be fully utilized. Excessive free space may also cause the cables to be loosely placed in the tray, increasing the risk of friction or confusion between the cables, which is not conducive to the neat arrangement and maintenance of the cables. In addition, adjacent cable trays are mostly connected to the same connector by bolts, which makes it inconvenient to disassemble and assemble the cable tray immediately. In scenarios where some large cable trays are installed at a large height, additional hoists need to be prepared when disassembling and releasing the cable tray, resulting in additional expenses.

[0017] 1. The main structure of the present invention includes a front guard plate, a rear guard plate, and a telescopic connection assembly. The front guard plate, the rear guard plate, and the telescopic connection assembly constitute a structure for accommodating and placing cables. The existence of the telescopic connection assembly makes the distance between the front guard plate and the rear guard plate adjustable, and finally makes the internal space of the accommodating and placing structure composed of the front guard plate, the rear guard plate, and the telescopic connection assembly adjustable, providing a flexible space adjustment function.

Only when the quick connection assembly is fully in place and the locking assembly continues to displace and the lock on the independent suspension assembly is released, can the cable tray be released or lifted. This design ensures that the cable tray is always in a stable state during the release process, reduces the risk of accidental falling, and improves the safety and accuracy of operation.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] Reference Figure 1-13A light high-strength cable bridge comprises a rear guard plate 2, a front guard plate 5, a docking plate 9, and a front sealing box 17. The sides of the rear guard plate 2 and the front guard plate 5 are provided with weight-reducing grooves 3 equidistantly arranged in the horizontal direction to reduce the weight of the entire bridge. Hot-dip galvanized steel is recommended as the material for the rear guard plate 2, the front guard plate 5, the docking plate 9, and the front sealing box 17. Hot-dip galvanized steel is used as the material for high-strength cable bridges. Hot-dip galvanized steel has excellent corrosion resistance and can effectively resist moisture and chemical corrosion in harsh environments, and is suitable for outdoor and industrial environments. Its high strength and durability can withstand large loads and ensure the stability and safety of the cable bridge. In addition, the cost of hot-dip galvanized steel is relatively moderate, and it has good economy and is suitable for most application scenarios. Compared with cold-dip galvanized steel, hot-dip galvanized steel has a thicker coating, provides longer-lasting protection, and reduces maintenance frequency and long-term operating costs.

[0037] A telescopic connection component for adjusting the accommodating space between the front guard plate 5 and the rear guard plate 2 is arranged between the front guard plate 5 and the rear guard plate 2, and the telescopic connection component includes a first connecting plate 7 and a second connecting plate 6. A horizontal plate 173 is symmetrically fixedly arranged at the bottom of the front sealing box 17, and docking columns 61 are fixedly arranged at both ends of one side of the first connecting plate 7 and the second connecting plate 6. Extension blocks 62 are symmetrically fixedly arranged on the second connecting plate 6 and the first connecting plate 7 away from the side of the docking columns 61. Docking blocks 51 are provided at the upper and lower edge positions of the front guard plate 5, and the docking column 61 on the side of the first connecting plate 7 is rotatably connected to the docking block 51, and the extension block 62 on the side of the first connecting plate 7 is rotatably connected to the docking column 61 on the second connecting plate 6, and the extension block 62 on the side of the second connecting plate 6 is rotatably connected to the upper and lower ends of the rear guard plate 2, and docking grooves 4 are arranged at the four corners of the rear guard plate 2 to avoid affecting the rotation of the first connecting plate 7 and the second connecting plate 6.

[0038] When the front guard plate 5, the rear guard plate 2, and the telescopic connecting assembly form a cable accommodation structure for installing multiple groups of cables, the multiple groups of cables will press down the first connecting plate 7 and the second connecting plate 6 at the bottom of the front guard plate 5 due to their weight, automatically driving the front guard plate 5 close to the rear guard plate 2 at an appropriate distance, so that the front guard plate 5, the rear guard plate 2, and the telescopic connecting assembly form a cable accommodation structure to form a housing cavity of appropriate size. At this time, the cable accommodation structure composed of the front guard plate 5, the rear guard plate 2, and the telescopic connecting assembly is flattened, and workers can continue to add cables to the flattened cable accommodation structure as needed.

[0039] A quick docking component for quickly docking telescopic connection components at the same horizontal height is arranged inside the docking plate 9. The quick docking component includes a docking frame 18, a common rod 20, and a composite spring 8. Docking blocks 51 are fixedly arranged at the edge positions of both sides of the front guard plate 5. The docking blocks 51 are movably inserted into the docking frame 18. The inner wall of the transverse displacement groove 13 is fixedly connected to one end of the composite spring 8, and the other end of the composite spring 8 is fixedly connected to the side of the transverse displacement block 19. Two docking blocks 51 are fixedly arranged at the edge position of one side of the front guard plate 5. The two docking blocks 51 and the docking frame 18 improve the connection stability between the front guard plate 5 and the docking plate 9.

[0040] When the quick-connect assembly is displaced to a certain position and the large cable tray can be released, the locking assembly needs to continue, and the displacement no longer locks the independent suspension assembly. At this time, the independent suspension assembly can release or lift the large cable tray. Only when the quick-connect assembly is fully in place and the locking assembly continues to displace and the lock on the independent suspension assembly is released, can the cable tray be released or lifted.

[0041] The outer sides of the two groups of transverse blocks 19 are both fixedly connected to the side of the common rod 20. An inverted L-rod 21 is fixedly set in the middle position of the side of the common rod 20. The end of the vertical section of the inverted L-rod 21 is set to a cylindrical shape. The setting of the inverted L-rod 21 makes it easy for the user to control the quick docking assembly from the bottom of the front guard plate 5 to release the front guard plate 5.

[0042] When the composite spring 8 is at its original length, the docking frame 18 is directly above the release slot 14, and the docking block 51 is inserted into the docking frame 18. At this time, the front guard plate 5, the rear guard plate 2, and the telescopic connection assembly in the adjacent corresponding positions constitute a cable storage structure that is stably docked with the docking plate 9.

[0043] The docking plate 9 is provided with an independent suspension component on one side of the quick docking component for the user to release the telescopic connection component from a high place or pull up the telescopic connection component from a low place. The docking plate 9 is provided with a receiving groove 12 at the upper and lower edge positions of the front side surface. The docking plate 9 is provided with an intermediate groove 15 in the middle position of the front side surface of the receiving groove 12. Transverse movement grooves 13 are provided at both ends of the front side surface of the receiving groove 12. The docking plate 9 is symmetrically provided with insertion holes 16 in the vertical direction. The receiving groove 12 provides a path for the transverse movement of the docking frame 18. The intermediate groove 15 is used to accommodate two rope winding wheels 26. The thickness of the intermediate groove 15 when viewed from above is much greater than the thickness of the receiving groove 12, so that most of the rope winding wheels 26 are wrapped in the intermediate groove 15, thereby reducing the possibility of the rope winding wheels 26 being accidentally hit by the outside world.

[0044] The independent suspension assembly includes a vertical ring 52, a suspension rope 10, a locking ring 11, and a rope wheel 26. The vertical ring 52 is fixedly arranged in the middle position of the side edge of the front guard plate 5. The docking plate 9 is symmetrically rotated and connected with a vertical column 23 inside the middle groove 15. The outer wall of the vertical column 23 is fixedly arranged with a rope wheel 26. One end of the suspension rope 10 is tied to the outer wall of the rope wheel 26. The suspension rope 10 passes through the hole of the vertical ring 52. The suspension rope 10 is fixedly arranged with locking rings 11 on both sides of the vertical ring 52. Figure 3 As shown, a front guard plate 5 is fixedly provided with vertical rings 52 at both ends. Therefore, when operating the quick release assembly, at least two workers or users are required to manipulate the quick docking assemblies at both ends of the front guard plate 5 to achieve the release or lifting of the front guard plate 5.

[0045] The outer wall of the vertical column 23 is provided with a locking assembly for locking the independent suspension assembly, and the locking assembly includes a limiting wheel 27, a limiting column 25, and a horizontal L-rod 24. The vertical column 23 is fixedly provided with a limiting wheel 27 on one side of the docking frame 18, and limiting holes 28 are equidistantly provided on the outer wall of the limiting wheel 27. One end of the horizontal L-rod 24 is fixedly connected to the side of the docking frame 18, and a limiting column 25 is fixedly provided at the other end of the horizontal L-rod 24. The limiting column 25 is movably inserted into the limiting hole 28. The horizontal L-rod 24 is arched when viewed from the front side. When the docking frame 18 is removed from the top of the release slot 14 to expose the docking block 51 at the top of the release slot 14, the limiting column 25 can be detached from the side of the limiting hole 28.

[0046] A rocking wheel 22 is fixedly provided on the top of the vertical column 23, and a crank handle 1 is fixedly provided at the top edge position of the rocking wheel 22. The number of limit holes 28 is set to a maximum, so when the limit column 25 moves laterally under the reset of the composite spring 8, it can be inserted into any limit hole 28 of the limit wheel 27 at any time. At this time, the rope wheel 26 stops rotating or releases the suspension rope 10, and an L-shaped connecting column 91 is fixedly provided at the edge position of the rear side surface of the docking plate 9.

[0047] The L-shaped column 91 includes a horizontal section and a vertical section. A vertical groove 910 is fixedly provided at the edge of the vertical section of the L-shaped column 91. The front cross-sectional shape of the vertical groove 910 is a U-shape. Workers can insert expansion bolts into the vertical groove 910 and drill holes in the installation wall and knock the expansion bolts into the holes. Multiple front guard plates 5 can be fixed on the wall. Since the front cross-sectional shape of the vertical groove 910 is a U-shape, the vertical height of the entire cable rack structure can be adjusted within a certain degree.

[0048] The front sealing box 17 has an avoidance gap 171 starting from the position of the vertical ring 52. The front sealing box 17 is used to protect the corresponding locking components and independent suspension components. The suspension rope 10 in the inner cavity of the front sealing box 17 passes through the avoidance gap 171. The horizontal section of the L-shaped connecting column 91 leaves enough space for the movement of the components on the front side of the front guard plate 5, namely the first connecting plate 7 and the second connecting plate 6, to avoid obstruction of the movement of the first connecting plate 7 and the second connecting plate 6, resulting in the front guard plate 5 and the rear guard plate 2 being unable to approach or move away from each other, and ultimately resulting in the front guard plate 5, the rear guard plate 2, and the telescopic connection assembly The structure for accommodating and placing the cable cannot change the accommodating space. The inverted L-rod 21 integrates the locking and releasing functions. The worker only needs to operate the inverted L-rod 21 to complete the locking and releasing actions, which simplifies the operation process. When handling large cable trays, the locking and releasing tasks can be completed more efficiently, reducing the complexity of manual operation.

[0049] An arc-shaped surface 174 is provided at the vertical edge position of the front side of the front sealing box 17, and a mounting hole 172 is provided at the bottom of the horizontal plate 173. After the bolt is inserted into the mounting hole 172, it is screwed into the bottom of the docking plate 9. The docking plate 9 has release grooves 14 at both ends of the accommodating groove 12. The top-view cross-sectional shape of the release groove 14 is similar to the top-view cross-sectional shape of the docking block 51, and the top-view cross-sectional size of the release groove 14 is larger than the top-view cross-sectional size of the docking block 51.

[0050] The specific implementation steps and principles of the present invention are as follows:

[0051] Take the initial state in which multiple sets of telescopic connection components are spliced ​​onto the docking plate 9 as an example. The vertical grooves 910 of the L-shaped columns 91 at the four corners of the docking plate 9 are screwed into the expansion bolts and fixed to the installation wall. At this time, the docking block 51 on the adjacent front guard plate 5 is inserted into the docking frame 18, and the limiting column 25 at the same horizontal height of the docking block 51 is inserted into any limiting hole 28 of the limiting wheel 27. At this time, the rope wheel 26 cannot rotate to release the suspension rope 10, and the cable accommodation structure composed of the released front guard plate 5, the rear guard plate 2, and the telescopic connection assembly cannot be released or suspended.

[0052] When it is necessary to release the front guard plate 5, the rear guard plate 2, and the telescopic connection assembly at the corresponding positions to form a structure for accommodating and placing the cables, two workers use ladders to climb to the two sides of the accommodating and discharging structure, and manually move the inverted L-rod 21 horizontally to compress the composite spring 8 to the limit position. During this process, the inverted L-rod 21 drives the two docking frames 18 to disengage from the inside of the docking block 51 through the common rod 20. At this time, the docking block 51 is above the release groove 14, and then the limit column 25 disengages from any limit hole 28 of the limit wheel 27. At this time, the rope wheel 26 can rotate to release the suspension rope 10, and gradually release the front guard plate 5, the rear guard plate 2, and the telescopic connection assembly at the end of the suspension rope 10 to form a structure for accommodating and placing the cables to the ground.

[0053] When the front guard plate 5, the rear guard plate 2, and the telescopic connecting assembly form a structure for accommodating and placing cables, and multiple groups of cables are installed, the weight of the multiple groups of cables will press down the first connecting plate 7 and the second connecting plate 6 at the bottom of the front guard plate 5, automatically driving the front guard plate 5 to approach the rear guard plate 2 to an appropriate distance, so that the front guard plate 5, the rear guard plate 2, and the telescopic connecting assembly form a structure for accommodating and placing cables to form a accommodating cavity of appropriate size.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
