Description

Technical Field

[0001] This utility model relates to the field of cable tray design technology, and in particular to an easy-to-disassemble ladder-type cable tray. Background Technology

[0002] Cable trays are tools used to house and protect cables. They can be attached to various buildings and pipe rack supports, with the cables running inside the trays. Currently, cable trays can be mainly divided into three categories: ladder-type cable trays, tray-type cable trays, and trough-type cable trays. Among them, ladder-type cable trays have advantages such as light weight, low cost, unique design, convenient installation, good heat dissipation, and good ventilation, and are commonly used for laying large-diameter, high-voltage power cables, as well as low-voltage power cables.

[0003] Traditional cable trays mainly consist of two side plates and a ladder beam connecting the side plates. The two ends of the ladder beam are fixed to the inner surfaces of the side plates by welding. The drawbacks of this design are that the welding process easily damages the protective layer (galvanized layer or fire-retardant coating) on ​​the surface of the side plates and ladder beam, weakening the cable tray's corrosion resistance or fire resistance. Furthermore, the welded cable trays are difficult to assemble and disassemble, and transportation is challenging. When localized damage occurs, the entire tray usually needs to be replaced, resulting in high maintenance costs. Utility Model Content

[0004] Based on this, the present invention provides an easy-to-disassemble ladder-type cable tray. Using the insertion holes, limiting plates, first bending parts, carrier plates, and screws, the ladder beams are connected to the side plates in a plug-in manner without welding, reducing damage to the protective layer. Moreover, quick disassembly and assembly can be achieved by turning the screws, allowing for disassembly and transportation, reducing transportation difficulty. Individual parts can be replaced, resulting in low maintenance costs.

[0005] An easily detachable ladder-type cable tray includes:

[0006] Two side panels; the two side panels are arranged in a mirror image symmetrically; the side panels have insertion holes; the bottom end of the side panel is bent inward and upward to form a first bend, and the top end face of the first bend is flush with the bottom end of the insertion hole; a horizontally extending carrier plate is provided on the outer side of the side panel; the carrier plate is flush with the bottom end of the insertion hole.

[0007] A ladder beam bridging the two side panels; the end of the ladder beam passes through an insertion hole from the inside of the side panel and rests on the carrier plate, with the bottom surface of the ladder beam abutting against the top of the first bend; the end of the ladder beam is also provided with a limiting plate abutting against the inside of the side panel; and

[0008] Screws are inserted between the side panel and the ladder beam; the screws lock the limiting plate to the inside of the side panel.

[0009] The aforementioned easily detachable ladder-type cable tray is assembled by inserting both ends of the ladder beam into the insertion holes of the side plate, so that the limiting plate of the ladder beam abuts against the inner side of the side plate. Then, the limiting plate is locked to the side plate with screws. At this point, both ends of the ladder beam are locked to the side plate, and the first bend of the side plate and the carrier plate both provide support for the ladder beam. Through this design, using insertion holes, limiting plates, the first bend, the carrier plate, and screws, the ladder beam is connected to the side plate in a plug-in manner, eliminating the need for welding, reducing damage to the protective layer. Furthermore, quick assembly and disassembly can be achieved by simply turning the screws, allowing for disassembly and transportation, reducing transportation difficulty. Individual parts can be replaced, resulting in low maintenance costs.

[0010] In one embodiment, the side plate has first connection holes at both ends for connecting expansion joints. When an expansion joint is installed between two adjacent cable trays, the expansion joint can be connected to the side plate through the first connection holes and bolts.

[0011] In one embodiment, the carrier plate has a second connecting hole for connecting the hanger rod. When the cable tray needs to be installed by hoisting, the carrier plate can be connected to the hanger rod without installing a crossarm, saving materials and improving installation efficiency.

[0012] In one embodiment, the bottom ends of both sides of the ladder beam are bent inward and upward to form a second bend. The second bend can form a reinforcing rib structure to enhance the structural stability of the ladder beam.

[0013] In one embodiment, a recessed groove is provided between the two second bends for the insertion of the crossarm. When the cable tray needs to be installed by hoisting, the crossarm can be inserted into the recessed groove from the end of the ladder beam, so that both ends of the crossarm extend to the outside of the side plate before being connected to the hanger. The installation is simple and the stability is strong.

[0014] In one embodiment, the ladder beam is provided with heat dissipation holes spaced sequentially along its length. These holes improve the heat dissipation efficiency of the cables laid on the ladder beam and guide any liquid adhering to the cables downwards.

[0015] In one embodiment, the easily detachable ladder-type cable tray further includes a cover plate connected between the two side plates. The cover plate can form a protective shield over the cables, preventing debris or liquid from falling directly onto the cables. Attached Figure Description

[0040] like Figures 1 to 11 As shown, it is an easily detachable ladder-type cable tray 100, which is an embodiment of the present invention.

[0041] like Figures 1 to 5 As shown, the easily detachable ladder-type cable tray 100 includes: two side plates 10, a ladder beam 20 bridging the two side plates 10, and screws 30 passing through the side plates 10 and the ladder beam 20. The side plates 10 and the ladder beam 20 are connected to form a storage groove structure for accommodating cables. The screws 30 are used to achieve a detachable connection between the side plates 10 and the ladder beam 20.

[0042] The following text, combined with Figures 1 to 11 Further explanation is provided regarding the aforementioned easily detachable ladder-type cable tray 100.

[0043] like Figure 1 and Figure 2 As shown, the two side panels 10 are arranged in a mirror-symmetrical configuration. Figure 6 and Figure 7 As shown, the side plate 10 has insertion holes 11 for connecting the ladder beam 20. The bottom end of the side plate 10 is bent inward and upward to form a first bend 12, and the top end face of the first bend 12 is flush with the bottom end of the insertion hole 11. Figure 4 As shown, a horizontally extending carrier plate 13 is provided on the outer side of the side plate 10, and the carrier plate 13 is flush with the bottom end of the insertion hole 11.

[0044] Considering that in practical applications, expansion joints need to be installed between two adjacent cable trays to prevent damage caused by thermal expansion and contraction, such as... Figure 6 and Figure 7 As shown, in this embodiment, the side plate 10 has first connecting holes 14 at both ends for connecting expansion joints. When expansion joints are installed between two adjacent cable trays, the expansion joints can be connected to the side plate 10 together through the first connecting holes 14 and bolts.

[0045] In this design, the side plate 10 can be obtained by cutting, punching, bending, electroplating, or other methods on a metal sheet. For example, the first bent portion 12 can be obtained simultaneously by punching and shearing the side plate 10 to form the insertion hole 11.

[0046] like Figure 3 and Figure 4 As shown, the end of the ladder beam 20 passes through the insertion hole 11 from the inside of the side plate 10 and is placed on the carrier plate 13, with the bottom surface of the ladder beam 20 abutting against the top of the first bend 12. Figure 8 As shown, the end of the ladder beam 20 is also provided with a limiting plate 21 that abuts against the inner side of the side plate 10.

[0047] like Figure 8 and Figure 9 As shown, the bottom ends of both sides of the ladder beam 20 bend inward and upward to form a second bend 22. The second bend 22 can form a reinforcing rib structure to enhance the structural stability of the ladder beam 20.

[0048] To improve heat dissipation efficiency, such as Figure 8 and Figure 9 As shown, in this embodiment, the ladder beam 20 is provided with heat dissipation holes 23 arranged at intervals along its length. The heat dissipation holes 23 help improve the heat dissipation efficiency of the cables laid on the ladder beam 20 and can guide the liquid adhering to the cables to drain downwards.

[0049] In this scheme, the ladder beam 20 can be obtained by cutting, punching, bending, electroplating and other methods on metal sheets.

[0050] like Figure 4 As shown, screw 30 secures the limiting plate 21 to the inner side of side plate 10. In this embodiment, screw 30 is used in conjunction with a nut. In other embodiments, threaded holes can be tapped into side plate 10 so that screw 30 can be screwed and fixed to side plate 10.

[0051] Brief description of working principle:

[0052] Combination Figures 3 to 5As shown, during assembly, both ends of the ladder beam 20 are inserted into the insertion holes 11 of the side plate 10, so that the limiting plate 21 of the ladder beam 20 abuts against the inner side of the side plate 10, and the periphery of the ends of the ladder beam 20 is restricted by the insertion holes 11. Next, the limiting plate 21 is locked to the side plate 10 with screws 30, achieving lateral positioning of the ladder beam 20. At this time, both ends of the ladder beam 20 are locked to the side plate 10, and the first bent portion 12 of the side plate 10 and the carrier plate 13 both provide support for the ladder beam 20.

[0053] Furthermore, considering that in practical applications, cable trays are mainly installed in three ways: hoisting, horizontal installation against a wall, and vertical installation in a shaft, with hoisting being the most common method, targeted improvements can be made to the hoisting installation method for cable trays.

[0054] For example, in application scenarios where load requirements are not high, such as Figure 7 , Figure 10 ,as well as Figure 11 As shown, in this embodiment, the carrier plate 13 may have a second connecting hole 131 for connecting the hanger rod 200. When the cable tray needs to be installed by hoisting, the carrier plate 13 and the ladder beam 20 together act as a crossbeam, eliminating the need to install a crossbeam. The carrier plate 13 can be connected to the hanger rod 200, saving materials and improving installation efficiency.

[0055] For example, in applications with high load requirements, a recessed groove 24 can be reserved between the two second bends 22 for the insertion of the crossarm. When the cable tray needs to be installed by hoisting, the crossarm can be inserted into the recessed groove 24 from the end of the ladder beam 20, so that both ends of the crossarm extend to the outside of the side plate 10 and then connect to the hanger 200. The installation is simple and the stability is strong.

[0056] In addition, such as Figure 1 and Figure 2 As shown, in this embodiment, the easily detachable ladder-type cable tray 100 may further include a cover plate 40 connected between the two side plates 10. The cover plate 40 can form a protective cover above the cables to prevent debris or liquid from falling directly onto the cables.

[0057] The aforementioned easy-to-assemble ladder-type cable tray 100 utilizes the insertion hole 11, the limiting plate 21, the first bending part 12, the carrier plate 13, and the screw 30 to connect the ladder beam 20 to the side plate 10 in a plug-in manner, eliminating the need for welding, reducing damage to the protective layer. Moreover, it can be quickly assembled and disassembled by turning the screw 30, allowing for disassembly and transportation, reducing transportation difficulty, and enabling replacement of individual parts, resulting in low maintenance costs.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
