Description

Technical Field

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

[0002] Cable trays are classified into various structures such as trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building (structure) supports and pipe rack supports. They should be characterized by simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors are also permitted.

[0003] Existing cable trays generally adopt an integral structure. During transportation, because their U-shaped hollow cross-section remains unchanged, the volume of their external structure is much larger than the volume of their solid material. This results in a large amount of wasted space in the transport vehicle, thus reducing the effective load capacity and leading to low space utilization. Typically, the cargo compartment volume is saturated far before reaching the vehicle's rated load capacity. This not only reduces the efficiency of single-trip transport and the logistics loading rate but also directly increases transportation costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foldable cable tray.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A foldable cable tray includes a tray body, which includes a tray base plate. Side plates are hinged to both sides of the tray base plate. Multiple fixed horizontal plates are detachably mounted on the bottom of the tray body. Fixed vertical plates are mounted on both sides of each fixed horizontal plate, located outside the side plates. A fixed end plate is mounted on the top of the outer wall of each fixed vertical plate. A first fixing hole for threaded insertion of a fixing bolt is provided on the fixed end plate. An assembly plate is detachably mounted on the fixed end plate. One end of the assembly plate has a limiting plate for engaging with the inner wall of the side plate when it is unfolded.

[0007] As a further embodiment of this utility model, the assembly plate is provided with a second fixing hole that communicates with the first fixing hole.

[0008] As a further embodiment of this utility model, the top end face of the fixed horizontal plate is provided with a docking plate, and the bottom end face of the cable tray base plate is provided with a plurality of docking grooves for the docking plate to be inserted.

[0009] As a further embodiment of this utility model, the inner wall of the fixed vertical plate is provided with a connecting plate, and the outer wall of the cable tray side plate is provided with a connecting groove corresponding to the docking groove and for the connecting plate to be inserted.

[0010] As a further embodiment of this utility model, the limiting plate is provided with a guide plate on the side near the cable tray side plate, and the inner wall of the cable tray side plate is provided with a guide groove corresponding to the connecting groove and for the guide plate to be inserted.

[0011] As a further embodiment of this utility model, the cable tray side plate is provided with first fastening holes on both sides for threaded insertion of fixing bolts, and the cable tray bottom plate is provided with second fastening holes that are connected to the first fastening holes when the cable tray side plate is folded.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model achieves two states for the cable tray side plates: foldable during transportation and unfoldable during use, through the hinged connection between the cable tray base plate and the two cable tray side plates. Compared with the traditional integral U-shaped cable tray, multiple folded cable trays can be stacked vertically, reducing the space occupied during transportation and maximizing the utilization of the transport vehicle's volume. At the same time, it improves transportation efficiency. The improvement in transportation efficiency directly reduces the number of trips required to complete the same freight volume, thereby reducing logistics costs. Attached Figure Description

[0023] Example

[0024] refer to Figures 1-6 A foldable cable tray includes a tray body 1, which includes a tray base plate 11. Side tray plates 12 are hinged to both sides of the tray base plate 11. Multiple fixed horizontal plates 13 are detachably mounted on the bottom of the tray body 1. Fixed vertical plates 14 located outside the side tray plates 12 are fixedly connected to both sides of each fixed horizontal plate 13. A fixed end plate 141 is fixedly connected to the top of the outer wall of each fixed vertical plate 14. A first fixing hole 142 for threaded insertion of a fixing bolt 15 is provided on the fixed end plate 141. An assembly plate 16 is detachably mounted on the fixed end plate 141. A limiting plate 161 is fixedly connected to one end of the assembly plate 16 for fitting against the inner wall of the side tray plate 12 when it is unfolded. The limiting plate 161 serves to limit the movement and prevent the side tray plate 12 from tilting inwards.

[0025] The assembly plate 16 has a second fixing hole 162 that communicates with the first fixing hole 142.

[0026] The fixed horizontal plate 13 is provided with a docking plate 131 on its top end face, and the bottom end face of the cable tray base plate 11 is provided with a plurality of docking slots 111 for the docking plate 131 to be inserted. Through the setting of the docking plate 131 and the docking slots 111, the fixed horizontal plate 13 is accurately positioned and initially connected under the cable tray base plate 11.

[0027] The inner wall of the fixed vertical plate 14 is provided with a connecting plate 143, and the outer wall of the cable tray side plate 12 is provided with a connecting groove 121 corresponding to the docking groove 111 and for the connecting plate 143 to be inserted. Through the setting of the connecting plate 143 and the connecting groove 121, the fixed vertical plate 14 is accurately positioned and initially connected on the outside of the cable tray side plate 12.

[0028] The limiting plate 161 is provided with a guide plate 163 on the side near the cable tray side plate 12. The inner side wall of the cable tray side plate 12 is provided with a guide groove 122 corresponding to the connecting groove 121 and for the guide plate 163 to be inserted. The connection strength between the limiting plate 161 and the cable tray side plate 12 is enhanced by the setting of the guide plate 163 and the guide groove 122.

[0029] The cable tray side plate 12 has first fastening holes 123 on both sides for threaded insertion of fixing bolts 15, and the cable tray bottom plate 11 has second fastening holes 112 that are connected to the first fastening holes 123 when the cable tray side plate 12 is folded.

[0030] refer to Figure 2 During transport preparation, since the two cable tray side plates 12 are hinged to the cable tray base plate 11, the two cable tray side plates 12 are first rotated inward and folded to the top of the cable tray base plate 11. Then, by threading the fixing bolts 15 into the first fastening hole 123 on the cable tray side plate 12 and the second fastening hole 112 on the cable tray base plate 11, the folded cable tray side plates 12 and the cable tray base plate 11 are firmly fixed, thereby ensuring that the cable tray can maintain a stable folded state during bumpy transport, preventing it from springing open on its own, and facilitating handling and stacking. Finally, by stacking multiple folded cable trays together, the space utilization rate of the transport vehicle is effectively improved.

[0031] refer to Figure 1In use, first insert the mating plate 131 on the fixed horizontal plate 13 into the mating groove 111 on the cable tray base plate 11.

Next, rotate and unfold the folded cable tray side plate 12 so that it is perpendicular to the cable tray base plate 11. During the rotation, the connecting plate 143 on the fixed vertical plate 14 is inserted into the connecting groove 121 on the cable tray side plate 12. At this time, the fixed vertical plate 14 is located on the outside of the cable tray side plate 12 and fits against the outer wall of the cable tray side plate 12 to prevent the cable tray side plate 12 from tilting outward. Then, assemble... The guide plate 163 on plate 16 is inserted into the guide groove 122 of the cable tray side plate 12. By threading the fixing bolt 15 into the second fixing hole 162 on the assembly plate 16 and the first fixing hole 142 on the fixing end plate 141, the assembly plate 16 and the fixing end plate 141 are firmly fixed. At this time, the limiting plate 161 is located inside the cable tray side plate 12 and fits against the inner wall of the cable tray side plate 12 to prevent the cable tray side plate 12 from tilting inward. The fixing vertical plate 14 and the limiting plate 161 firmly clamp the cable tray side plate 12 between them to ensure that the cable tray side plate 12 is stably fixed in a position perpendicular to the cable tray base plate 11.
