Description

Technical Field

[0001] The utility model belongs to the field of cable laying, in particular to an assembled cable bridge. Background Art

[0002] Cable laying requires laying and installing cables along surveyed routes to form cable lines. This process requires consideration of multiple factors to ensure the safety, reliability and efficiency of cable lines. When installing cables inside buildings, industrial facilities and other places, cable trays are often used to support and fix cables to ensure the safety, neatness and reliability of cable routing: cable trays can fix cable lines in the air to avoid contact with the ground or other facilities, thereby ensuring the safety and stability of the cables. At the same time, the use of cable trays can make cable lines orderly and uniformly wired, making the entire system look neat and beautiful, and easy to maintain and manage.

[0003] There are many types of cable trays, one of which is the trough type cable tray, whose structure includes a bottom plate and side plates arranged on both sides of the bottom plate. The bottom plate and side plates of most trough type cable trays are an integrated structure with a fixed internal space, and it is impossible to increase or decrease units at any time to match different numbers of cables according to different cable laying occasions; at the same time, the integrated structure occupies more space during transportation, which greatly increases the transportation cost; and the trough type cable tray has a cavity structure inside, and the side plate supporting force is weak, so the trough type cable tray is easily squeezed and damaged during transportation and stacking. The damaged trough type cable tray needs to be replaced as a whole, which increases the cost of use.

[0004] To this end, the utility model proposes an assembled cable bridge. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes an assembled cable tray, which solves the problem that the existing trough-type cable tray is integrally formed and cannot increase or decrease units at any time to match the number of cables according to actual on-site needs.

[0006] To achieve the above-mentioned purpose, according to an embodiment of the first aspect of the utility model, an assembled cable tray is proposed, comprising: side panel one, side panel two and a plurality of bottom panels, wherein the side panel one, side panel two and bottom panels have the same length; the side panel one is fixedly installed with a T-shaped block along the length direction, the side panel two is provided with a T-shaped groove along the length direction, the bottom panel is fixedly installed with a T-shaped block on one side along the length direction, and is provided with a T-shaped groove on the other side, wherein the T-shaped groove and the T-shaped block are adapted to each other.

[0007] Preferably, a limiting mechanism 1 is fixedly installed at a lower portion of the side panel, a limiting mechanism 2 is fixedly installed at a lower portion of the side panel, and a limiting mechanism 1 and a limiting mechanism 2 are fixedly installed at a lower portion of the bottom plate, respectively, and the limiting mechanism 1 and the limiting mechanism 2 are plug-connected.

[0008] Preferably, the limiting mechanism 1 includes a mounting plate 1 and a latch; the limiting mechanism 2 includes a mounting plate 2, a rotating shaft and a fixed block; the mounting plate 1 is fixedly mounted on the side plate 1 and the lower part of the bottom plate, respectively, and the latch is fixedly mounted on the mounting plate 1; the mounting plate 2 is fixedly mounted on the side plate 2 and the lower part of the bottom plate, respectively, the rotating shaft and the fixed block are fixedly mounted on the mounting plate 2, a plug-in block is rotatably connected to the rotating shaft, and a lever is fixedly mounted on the plug-in block; a spring is installed between the plug-in block and the fixed block, and both ends of the spring are fixedly connected to the plug-in block and the fixed block, respectively.

[0009] Preferably, the rotating shaft and the shifting rod are respectively located on both sides of the plug-in block, and the connection position between the spring and the plug-in block and the connection position between the shifting rod and the plug-in block are on the same side.

[0010] Preferably, the side panel one and the side panel two are both "L"-shaped, including a vertical panel and a horizontal panel, the T-shaped groove and the T-shaped block are both arranged on the horizontal panels of the side panel one and the side panel two along the length direction, the load-bearing plate one is fixedly installed on the outer sides of the side panel one and the side panel two, the load-bearing plate two is fixedly installed on the lower part of the bottom plate, and the load-bearing plate one and the load-bearing plate two are installed in the same position along the length direction; after the side panel one, the side panel two and the bottom plate are plugged and connected, a buckle is fixedly installed at the connection between the load-bearing plate one and the load-bearing plate two.

[0011] Preferably, the side panel 1 and the side panel 2 are both fixedly mounted with a connecting plate at one end along the length direction, and a plugging plate is fixedly mounted at the other end, and the connecting plate and the plugging plate are adapted to each other.

[0012] Preferably, the connecting plate and the plug plate are both provided with a plurality of threaded holes, and the threaded holes on the connecting plate are provided at positions matching those of the threaded holes on the plug plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the cable tray is composed of a side plate 1, a side plate 2 and a plurality of bottom plates, and has standardized T-shaped blocks and T-shaped slots. This modular design allows the tray to be freely combined and expanded as needed; when the number of cables increases and a larger tray is needed to accommodate the cables, the user only needs to simply increase the number of bottom plates, and then insert the T-shaped blocks of the newly added bottom plates into the T-shaped slots of the existing bottom plates.

At the same time, during long-distance transportation, this design can significantly reduce the risk of damage caused by collision or extrusion during transportation. When some components are damaged, only the corresponding components need to be replaced, without replacing the entire tray, thereby reducing maintenance costs;

[0014] When the side panel 1, the side panel 2 and the bottom panel are plugged and slidably installed, the pin presses the plug-in block to rotate around the rotating shaft. At this time, the spring is compressed until the pin and the plug-in block are locked with each other and the spring is reset. The limiting mechanism 1 and the limiting mechanism 2 can ensure that the side panel 1, the side panel 2 and the bottom panel can be accurately aligned during assembly, which reduces the adjustment time during the assembly process and significantly improves the assembly efficiency. At the same time, the locking function of the limiting mechanism 1 and the limiting mechanism 2 after positioning enables a stable connection to be formed between the components after the side panel 1, the side panel 2 and the bottom panel are plugged in. When the cable tray is disassembled, the lever is moved to make the plug-in block rotate around the rotating shaft and compress the spring. At this time, the pin and the plug-in block are no longer locked, and the cable tray can be slid and disassembled, and the disassembly process is convenient and fast.

DETAILED DESCRIPTION

[0023] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 7 As shown, an assembled cable tray comprises: a side plate 1, a side plate 2 and a plurality of bottom plates 3, wherein the side plate 1, the side plate 2 and the bottom plate 3 are of the same length; the side plate 1 and the side plate 2 are both "L"-shaped, comprising a vertical plate and a horizontal plate, the side plate 1 is fixedly mounted with a T-shaped block 5 along the length direction, the side plate 2 is provided with a T-shaped slot 4 along the length direction, the bottom plate 3 is fixedly mounted with a T-shaped block 5 on one side along the length direction, and is provided with a T-shaped slot 4 on the other side, the T-shaped slot 4 and the T-shaped block 5 are both arranged on the horizontal plates of the side plate 1 and the side plate 2, wherein each T-shaped slot 4 and the T-shaped block 5 are mutually adapted;

[0025] The cable tray is composed of a side plate 1, a side plate 2 and a plurality of bottom plates 3, each of which has the same length and has standardized T-blocks 5 and T-slots 4 interfaces; this modular design allows the tray to be freely combined and expanded as needed, like building blocks; when the number of cables increases and a larger tray is needed to accommodate the cables, the user only needs to simply increase the number of bottom plates 3, and then insert the T-blocks 5 of the newly added bottom plates 3 into the T-slots 4 of the existing bottom plates 3. This expansion process is fast and convenient, and no complicated adjustment or modification is required; therefore, the user can avoid the waste caused by purchasing trays of multiple specifications at one time;

[0026] The design of the assembled cable tray allows its components to be transported separately, thus greatly optimizing the transportation space. Compared with the traditional integrated cable tray, the components of the assembled cable tray can be packaged separately, reducing the overall volume and making it easier to load and transport on vehicles, ships or airplanes. At the same time, during long-distance transportation, this design can significantly reduce the risk of damage caused by collision or extrusion during transportation.

[0027] When some parts are damaged due to various reasons, for assembled cable trays, only the corresponding parts need to be replaced, without replacing the entire tray, which reduces the maintenance cost;

[0028] like Figure 4-Figure 6 As shown, the lower part of the side panel 1 is fixedly installed with a limiting mechanism 1 6, the lower part of the side panel 2 is fixedly installed with a limiting mechanism 2 7, and the lower part of the bottom plate 3 is respectively fixedly installed with a limiting mechanism 1 6 and a limiting mechanism 2 7, and the limiting mechanism 1 6 and the limiting mechanism 2 7 are plug-connected;

[0029] The limiting mechanism 1 6 includes a mounting plate 1 61 and a latch 62; the limiting mechanism 2 7 includes a mounting plate 2 71, a rotating shaft 74 and a fixed block 72; the mounting plate 1 61 is fixedly mounted on the side plate 1 and the lower part of the bottom plate 3, respectively, and the latch 62 is fixedly mounted on the mounting plate 1 61; the mounting plate 2 71 is fixedly mounted on the side plate 2 2 and the lower part of the bottom plate 3, respectively, the rotating shaft 74 and the fixed block 72 are fixedly mounted on the mounting plate 2 71, a plug-in block 75 is rotatably connected to the rotating shaft 74, and a lever 76 is fixedly mounted on the plug-in block 75; a spring 73 is installed between the plug-in block 75 and the fixed block 72, and the two ends of the spring 73 are fixedly connected to the plug-in block 75 and the fixed block 72, respectively; the rotating shaft 74 and the lever 76 are respectively located on both sides of the plug-in block 75, and the connection position of the spring 73 and the plug-in block 75 is on the same side as the connection position of the lever 76 and the plug-in block 75;

[0030] When the side panels 1, 2 and 3 are connected, they slide against each other. During the sliding process, the latch 62 presses the plug block 75 to rotate around the rotating shaft 74. At this time, the spring 73 is compressed until the latch 62 and the plug block 75 are locked with each other, and the spring 73 is reset; the side panels 1, 2 and 3 are installed; through the limiting mechanism 1 6 and the limiting mechanism 2 7, the side panels 1, 2 and 3 can quickly and accurately find the corresponding positions; it can ensure that the side panels 1, 2 and 3 can be accurately aligned during assembly, which reduces the adjustment time during the assembly process, thereby significantly improving the assembly efficiency; at the same time, the locking function of the limiting mechanism 1 6 and the limiting mechanism 2 7 after positioning makes it possible to form a stable connection between the components after the side panels 1, 2 and 3 are connected. The cable tray is not easily displaced or deformed when subjected to external forces, thereby enhancing the structural stability of the cable tray;

[0031] When the cable tray is disassembled, the lever 76 is moved to rotate the plug block 75 around the shaft 74 and compress the spring 73. At this time, the latch 62 and the plug block 75 are no longer locked, and the cable tray can be slidably disassembled;

[0032] A load-bearing plate 10 is fixedly installed on the outer side of the side panel 1 and the side panel 2, and a load-bearing plate 2 11 is fixedly installed on the lower part of the bottom plate 3. The load-bearing plate 10 and the load-bearing plate 2 11 are installed at the same position along the length direction; after the side panel 1, the side panel 2 and the bottom plate 3 are plugged and connected, a buckle 12 is fixedly installed at the connection between the load-bearing plate 10 and the load-bearing plate 2 11, and the load-bearing plate 10 and the load-bearing plate 2 11 are fixedly connected by the buckle 12; in actual installation, the top of the load-bearing plate 10 is fixedly connected to the roof of the building;

[0033] The solid structure and effective bearing capacity of the load-bearing plate 10 and the load-bearing plate 2 11 enable the cable tray to bear the weight of the cables for a long time without being easily damaged. This design prolongs the service life of the cable tray and reduces the frequency of maintenance and replacement. At the same time, the setting of the load-bearing plate 10 and the load-bearing plate 2 11 effectively transfers the weight of the cable tray and the cables thereon to the building structure, effectively preventing the cable tray structure from being deformed or damaged due to overload.

[0034] like Figure 7 As shown, the side plate 1 and the side plate 2 are fixedly installed with a connecting plate 8 at one end along the length direction, and a plugging plate 9 is fixedly installed at the other end, and the connecting plate 8 and the plugging plate 9 are adapted; the connecting plate 8 and the plugging plate 9 are both provided with a plurality of threaded holes, and the threaded holes on the connecting plate 8 match the threaded holes on the plugging plate 9; multiple groups of cable trays are connected together by the connecting plate 8 and the connecting plate 8;

[0035] The staff only needs to insert the plug plate 9 into the connecting plate 8 and fix it through the threaded holes to complete the connection of the cable tray. The design of the connecting plate 8 and the plug plate 9, plus the matching threaded holes, make the connection between multiple groups of cable trays tighter and more stable; this connection method can withstand greater tension and shear force, and improves the connection strength of the entire cable tray system.

[0036] The working principle of the utility model is as follows: the T-shaped blocks 5 and T-shaped grooves 4 of the side panels 1, 2 and 3 are adapted to each other and connected by sliding, and the basic assembly of the cable tray can be quickly completed; when the side panels 1, 2 and 3 are plugged in, the limiting mechanism 1 6 and the limiting mechanism 2 7 work together, and during the sliding process, the latch 62 presses the plug-in block 75 to rotate around the rotating shaft 74, and the spring 73 is compressed until the latch 62 and the plug-in block 75 are locked with each other, and the spring 73 is reset; at this time, the side panels 1, 2 and 3 are installed; then the load-bearing plate 10 and the load-bearing plate 2 11 are connected into a whole through the buckle 12;

[0037] When connecting multiple groups of cable trays, it is only necessary to insert the plug plate 9 into the connecting plate 8 and fix it through the threaded holes to complete the tight connection between the multiple groups of cable trays.

[0038] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
