Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, in particular to a fixed cable tray. Background Technique

[0002] Cables are important basic profiles in modern society, playing roles such as power and signal transmission. During their use, it is necessary to ensure the stability of their overall state. Therefore, corresponding installation structures are required. According to different usage scenarios, the installation structures also vary. A relatively common one is the bridge structure used inside buildings. Most existing bridges are composed of cable troughs and covers. The cable trough is the structure for placing cables.

[0003] When installing cables, it is necessary to drag the cables in the cable tray. During the dragging process, the surface layer of the cable will rub against the surface of the cable tray. Since the cable itself is relatively heavy, excessive friction will damage the surface layer of the cable, increasing the risk of electric leakage during the use of the cable. In view of the above problems, a fixed cable tray is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the shortcoming of damaging the surface layer of the cable in the prior art, and a fixed cable tray is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A fixed cable tray includes a cable tray. One end of the cable tray is fixedly connected with a first fixing plate, and a first bolt hole is opened on the first fixing plate. One side of the cable tray is fixedly connected with a second fixing plate. A cable trough is opened on the inner bottom surface of the cable tray. A roller trough is opened at the bottom of the cable trough. A bearing is fixedly connected inside the roller trough. A roller is slidably connected to the outside of the bearing. One end of the cable tray far from the first fixing plate is fixedly connected with a first slot, and a second bolt hole is opened on the first slot. A second slot is opened at one end of the cable tray far from the second fixing plate.

[0007] The above technical scheme further includes:

[0008] Heat dissipation fins are opened on the side surface of the cable tray. There are three groups of heat dissipation fins opened on the cable tray, which are evenly distributed on both sides of the cable tray.

[0009] The second bolt hole is threadedly connected with a bolt. The bolt can fixedly connect the first bolt hole and the first slot through threaded connection. The first bolt hole and the first slot have the same size and can be inserted.

[0010] The second fixing plate and the second slot have the same size and can be inserted.

[0011] The bottom of the cable trough is provided with heat dissipation holes, and three groups of heat dissipation holes are evenly arranged at the bottom of the cable trough.

[0012] The roller is provided with strip-shaped protrusions for increasing friction and preventing the cable from sliding and rubbing on the roller.

[0013] The roller can rotate around a bearing fixedly connected inside the roller groove.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, through the mutual cooperation of the first fixing plate and the first slot, the second fixing plate and the second slot, the bridge is fixed, and then the first bolt hole and the second bolt hole are connected by screw threads of the bolt, which facilitates the installation of the bridge by workers and reduces the construction time.

[0016] 2. In the utility model, when dragging the cable, since the roller can change the original sliding friction into rolling friction, the damage to the cable surface is greatly reduced, and the probability of subsequent leakage accidents is reduced. At the same time, a large amount of heat will be generated during the later use of the cable, and the heat dissipation holes and heat dissipation fins can timely dissipate the heat, preventing heat accumulation and reducing the probability of fire accidents.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] As Figures 1-4 shown, a fixed cable tray proposed by the present utility model includes a cable tray 1. One end of the cable tray 1 is fixedly connected to a first fixing plate 2. A first bolt hole 3 is opened on the first fixing plate 2. One side of the cable tray 1 is fixedly connected to a second fixing plate 4. A cable groove 8 is opened on the inner bottom surface of the cable tray 1. A roller groove 15 is opened at the bottom of the cable groove 8. A bearing 11 is fixedly connected inside the roller groove 15. A roller 10 is slidably connected to the outside of the bearing 11. One end of the cable tray 1 away from the first fixing plate 2 is fixedly connected to a first slot 7. A second bolt hole 6 is opened on the first slot 7. A second slot 9 is opened at one end of the cable tray 1 away from the second fixing plate 4.

[0025] A bolt 5 is threadedly connected to the second bolt hole 6. The bolt 5 can fixedly connect the first bolt hole 3 and the first slot 7 through threaded connection. The first bolt hole 3 and the first slot 7 have the same size and can be inserted.

[0026] The second fixing plate 4 and the second slot 9 have the same size and can be inserted.

[0027] In this embodiment, when installing the cable tray, the installer places two groups of cable trays 1 on the same horizontal plane, and aligns the first fixing plate 2 and the first slot 7 on the side, and the second fixing plate 4 and the second slot 9. Since the first fixing plate 2 and the first slot 7 have the same size, and the second fixing plate 4 and the second slot 9 have the same size, insert the first fixing plate 2 into the first slot 7, and at the same time, the second fixing plate 4 will also be inserted into the second slot 9. Then, insert a bolt 5 with the same size as the first bolt hole 3 and the second bolt hole 6 through the first bolt hole 3 and the second bolt hole 6 and thread them together. Repeat this process to install multiple sections of cable trays.

[0028] Embodiment 2

[0029] As Figures 1-4 shown, based on Embodiment 1, heat dissipation fins 14 are opened on the side of the cable tray 1. There are three groups of heat dissipation fins 14 opened on the cable tray 1, which are evenly distributed on both sides of the cable tray 1.

[0030] Heat dissipation holes 13 are opened at the bottom of the cable groove 8. There are three groups of heat dissipation holes 13 evenly arranged at the bottom of the cable groove 8.

[0031] The roller 10 is provided with strip-shaped protrusions 12 that increase friction and prevent the cable from sliding and rubbing on the roller 10.

[0032] The roller 10 can rotate around the bearing 11 fixedly connected inside the roller groove 15.

[0033] In this embodiment, when laying the cable after the bridge 1 is spliced, a roller groove 15 is provided at the bottom of the cable groove 8, and a roller 10 is provided inside the roller groove 15. When the cable is placed inside the cable groove 8, the surface of the cable contacts the stripe protrusions 12 on the surface of the roller 10. When dragging the cable, since the roller 10 can rotate around the bearing 11 fixedly connected inside the roller groove 15, the original sliding friction is changed into rolling friction, greatly reducing the damage to the cable surface and reducing the probability of later leakage accidents. At the same time, a large amount of heat will be generated during the later use of the cable. The heat dissipation holes 13 and heat dissipation fins 14 provided on the surface of the bridge 1 can timely dissipate the heat, preventing heat accumulation and reducing the probability of fire accidents.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
