Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a cable tray with a compensation structure. Background Technology

[0002] Cable trays are core facilities in power and communication systems used to support, protect, and manage cables. They are frame structures made of metal or composite materials (such as steel, aluminum alloy, and fiberglass) to achieve orderly laying and protection of cables. They are widely used in data centers, industrial plants, commercial buildings, and other fields, providing safe and reliable solutions for power transmission, signal control, and data communication.

[0003] Currently, cable trays are mostly semi-enclosed trays with concave structures. The upward folding edges on both sides form a protective space, which can effectively wrap the cables to protect them from dust, moisture and mechanical impact. They are both aesthetically pleasing and functional. During installation, the cable tray is connected to the building facade through mounting plates. After the cables are laid on the cable tray, the tray is subjected to the pressure of the cables for a long time, which makes the cable tray prone to bending. This further affects the connectors and expansion joints on the cable tray, causing them to deform and fail. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cable tray with a compensation structure, which solves the problem that cable trays bend under long-term heavy cable pressure, leading to deformation and failure of various structures.

[0005] According to an embodiment of this utility model, a cable tray with a compensation structure includes a cable tray body, a mounting plate, ribs, and reinforcing rods. The cable tray body is concave, with a protruding block at one end of each cable tray body and an overlapping groove at the other end of each cable tray body. The mounting plate has several connecting holes, and the mounting plate and the cable tray body are detachably connected through the connecting holes. There are two ribs, which are symmetrically arranged at both ends of the bottom width direction of the cable tray body. One end of the reinforcing rod is connected to the mounting plate through a connecting plate, and the other end of the reinforcing rod has a support block. The top of the support block has a first slot for the ribs to be inserted.

[0006] Compared with the prior art, this utility model has the following beneficial effects: the cable tray body is connected to the building through the mounting plate, a part of the protruding block of the adjacent cable tray body is inserted into the overlapping groove of another cable tray body, so that there is a displacement distance between the two. The first slot at the top of the support block is engaged with the rib at the bottom of the cable tray body. When the reinforcing rod is installed on the mounting plate and the bottom of the cable tray body, the rib can restrict the movement of the support block, thereby greatly enhancing the overall load-bearing capacity of the cable tray body and effectively limiting the bending of the cable tray body during the process of carrying cables.

[0007] Furthermore, it also includes: support platforms, of which there are several, each of which is detachably mounted on one side of the mounting plate, with the top surface of the support platform abutting against the bottom of the cable tray body.

[0008] Furthermore, each support platform has a mounting block on the side facing the mounting plate, and the mounting plate has several second slots for the mounting blocks to be inserted. The top of the support platform has a third slot that matches the rib.

[0009] Furthermore, it also includes an auxiliary support plate, which is rotatably mounted at the bottom of one end of the cable tray body via a pivot.

[0010] Furthermore, the cable tray body has several ventilation holes.

[0011] Furthermore, drainage holes are provided inside the lap joint groove.

[0012] Furthermore, the connecting holes are symmetrically arranged at both ends of the mounting plate in the width direction, and the spacing between the two connecting holes in the width direction of the mounting plate is the same as the width of the cable tray body. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 3As shown in the figure, this utility model embodiment proposes a cable tray with a compensation structure, including a cable tray body 1, a mounting plate 4, ribs 6, and reinforcing rods 7. The cable tray body 1 is concave, with a protruding block 2 at one end and an overlapping groove 3 at the other end. The mounting plate 4 has several connecting holes 5, and the mounting plate 4 and the cable tray body 1 are detachably connected through the connecting holes 5. There are two ribs 6, which are symmetrically arranged at both ends of the bottom width direction of the cable tray body 1. One end of the reinforcing rod 7 is connected to the mounting plate 4 through a connecting plate 8, and the other end of the reinforcing rod 7 has a support block 9. The top of the support block 9 has a first slot for the ribs 6 to be inserted. When installing this cable tray, the mounting plate 4 is pre-installed on the building, and then the cable tray body 1 is connected to the mounting plate 4 through the connecting holes 5. Then, the first slot on the top of the support block 9 is engaged with the ribs 6, and the connecting plate 8 is connected and fixed to the mounting plate 4, so that the reinforcing rod 7 forms a triangular support between the cable tray body 1 and the mounting plate 4. When installing another cable tray body 1, the above steps are repeated, and a part of the protruding block 2 of the other cable tray body 1 is inserted into the overlapping groove 3 of the previous cable tray body 1, thereby providing support for the cable tray body 1 installed later.

[0020] In one embodiment, the mounting plate 4 has six connecting holes 5 arranged in an array, and the cable tray body 1 also has countersunk holes corresponding to the connecting holes 5. The mounting plate 4 and the cable tray body 1 can be fixed to the building by passing a fastener through the countersunk hole and the connecting hole 5 in sequence, or the mounting plate 4 and the cable tray body 1 can be fixed in advance.

[0021] After the reinforcing rod 7 is installed in place, the connecting plate 8 at one end of the reinforcing rod 7 is fixed to the mounting plate 4, and the support block 9 at the other end of the reinforcing rod 7 supports the bottom of the cable tray body 1 away from the mounting plate 4. At this time, one end of the rib 6 is inserted into the first slot at the top of the support block 9. By setting the rib 6 at the bottom of the cable tray body 1, the rib 6 increases the strength of the cable tray body 1. Due to the presence of the reinforcing rod 7, the triangular support formed by the reinforcing rod 7 strengthens the strength of the end of the cable tray body 1 away from the mounting plate 4. The rib 6 being inserted into the first slot restricts the displacement of the support block 9 in the width direction of the cable tray body 1, further restricting the bending of the cable tray body 1, thereby improving the support strength of the cable tray body 1 and preventing the cable tray body 1 from being affected by bending.

[0022] like Figure 2 and Figure 4As shown, further comprising: a support platform 10, wherein there are several support platforms 10, each support platform 10 being detachably mounted on one side of the mounting plate 4, with the top surface of the support platform 10 abutting against the bottom of the cable tray body 1. In this embodiment, the cross-section of the support platform 10 is a right-angled triangle, with the two right-angled sides of the support platform 10 abutting against the side wall of the mounting plate 4 and the bottom of the cable tray body 1, respectively. By supporting the bottom of the cable tray body 1 with the support platforms 10, the load-bearing capacity of the cable tray body 1 for cables is improved.

[0023] like Figure 4 As shown, each support platform 10 has a mounting block 11 on the side facing the mounting plate 4. The mounting plate 4 has several second slots for inserting the mounting blocks 11, and the top of the support platform 10 has a third slot that matches the ribs 6. When connecting the support platform 10 to the mounting plate 4, the mounting blocks 11 are directly inserted into the second slots on the mounting plate 4, and then the cable tray body 1 is supported on the support platform 10. After the top of the support platform 10 abuts against the bottom of the cable tray body 1, the movement of the support platform 10 is limited by the ribs 6 because they are engaged in the third slots, preventing it from moving. In this way, the support platform 10 can be installed on the mounting plate 4 without screws or other fasteners, making installation and disassembly more convenient.

[0024] like Figure 2 and Figure 3 As shown, it further includes an auxiliary support plate 12, which is rotatably mounted at the bottom of one end of the cable tray body 1 via a pivot. Specifically, the auxiliary support plate 12 is located at the bottom of the end of the cable tray body 1 near the overlapping groove 3. When the two cable tray bodies 1 are overlapped, by rotating the auxiliary support plate 12, the free end of the auxiliary support plate 12 extends into the bottom of the other cable tray body 1 and is in close contact with its bottom, thereby forming a support.

[0025] like Figure 1 and Figure 3 As shown, the cable tray body 1 further includes several ventilation holes 13. These ventilation holes 13 dissipate heat generated by the cables during current transmission, promote airflow in the top area of ​​the cable tray body 1, and prevent heat accumulation. Specifically, the ventilation holes 13 on the two wings of the concave cable tray body 1 are circular, and these ventilation holes 13 correspond to the connection holes 5 on the mounting plate 4.

[0026] like Figure 3 As shown, a drainage hole 14 is further provided in the overlap groove 3. When this device is installed outdoors, since part of the protruding block 2 is in the overlap groove 3, rainwater is easy to accumulate in the overlap groove 3. The drainage hole 14 can drain this part of the water in time, avoiding long-term corrosion of the cable tray body 1 by rainwater.

[0027] Furthermore, the connecting holes 5 are symmetrically arranged at both ends of the mounting plate 4 in the width direction, and the distance between the two connecting holes 5 in the width direction of the mounting plate 4 is the same as the width of the cable tray body 1. Specifically, the distance between the two connecting holes 5 in the width direction of the mounting plate 4 is the same as the distance between the two wings of the concave cable tray body 1. In one embodiment, the concave cable tray body 1 is suspended, with the mounting plate 4 installed on the top of the building. The cable tray body 1 is suspended by pulling ropes through the ventilation holes 13 on the two wings, without the need for additional openings.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
