Description

Technical Field

[0001] This utility model belongs to the field of cable laying structure technology, specifically relating to a cable tray. Background Technology

[0002] In modern buildings and industrial facilities, cables serve as crucial carriers of power transmission and information delivery, making the standardization and safety of their installation paramount. Cable trays, as structural components used to support and lay cables, are widely used in electrical installations of various buildings, cable routing in industrial plants, and data centers. Early, commonly used open-style cable trays, while offering advantages such as lower cost and relatively simple installation, lacked a closed protective structure, leaving cables directly exposed to the external environment and susceptible to dust, moisture, and mechanical impacts. Furthermore, the open structure failed to effectively prevent small animals like rodents from gnawing on the cables, further increasing the risk of damage. To address these issues with open-style cable trays, enclosed cable trays were developed. Enclosed cable trays, through their closed top and side walls, provide a degree of protection for the cables, reducing the damage caused by external factors to a certain extent.

[0003] However, existing enclosed cable trays present numerous inconveniences in terms of inspection and maintenance. When it is necessary to inspect, repair, or replace the cables inside the tray, it is usually necessary to remove the entire tray cover, which not only consumes a lot of time and manpower, but also easily causes secondary damage to the tray and cables during disassembly and installation. Especially in some confined spaces or high installation positions, the operation of removing the cover is even more difficult, increasing the difficulty and risk of maintenance. To address this, this application proposes a new type of cable tray. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This embodiment provides a cable tray, the structural diagram of which is shown below. Figures 1-5 As shown, it includes a cable tray 1, a bottom cover plate 3, and a quick-release component 4.

[0028] In this embodiment, the cable tray 1 serves as the main frame of the cable bridge. The top and side walls of the cable tray 1 form a semi-enclosed space to accommodate cables. Support rods 5 are horizontally arranged at the bottom of the cable tray 1, distributed along the width of the cable tray 1, and several rods 5 are arranged side-by-side, evenly distributed. This structural design provides support for the cables placed within the cable tray 1.

[0029] Furthermore, in this embodiment, multiple pairs of hangers 2 are provided at the top of the cable tray 1, and a connecting block 8 is connected to the bottom end of each pair of hangers 2. The connecting block 8 is fixedly connected to both sides of the top of the cable tray 1. A mounting plate 7 is fixedly connected to the top of the hanger 2. The mounting plate 7 has mounting holes, through which expansion bolts can be used to fix the entire cable tray to the building or other supporting structure, realizing the installation and positioning of the cable tray. In order to further enhance the connection stability between the hanger 2 and the connecting block 8, the bottom end of the hanger 2 passes through the connecting block 8, and a pair of nuts 9 are threaded on the bottom end of the hanger 2. The pair of nuts 9 are located above and below the connecting block 8, respectively. By tightening the nuts 9, the hanger 2 can be firmly fixed to the connecting block 8 to prevent the hanger 2 from loosening.

[0030] In a further embodiment, a bottom cover plate 3 is provided through the bottom wall of the cable tray 1. The length of the bottom cover plate 3 is less than the length of the cable tray 1, and multiple bottom cover plates 3 are provided, which together cover the bottom of the cable tray 1. This segmented design allows only the part of the bottom cover plate 3 that needs to be opened for inspection or maintenance of the cables in the cable tray 1, without having to remove the entire bottom cover plate 3, thus improving maintenance efficiency.

[0031] In this embodiment, one side of each bottom cover plate 3 is hinged to the cable tray 1, allowing the bottom cover plate 3 to rotate around the hinge point. A quick-release piece 4 is provided between the other side of the bottom cover plate 3 and the cable tray 1, enabling quick connection and rotational opening of the bottom cover plate 3 and the cable tray 1. Several through holes 6 are provided on the bottom cover plate 3, arranged in a row. These through holes 6 serve a ventilation and heat dissipation function, helping to reduce the heat generated by the cables running inside the cable tray 1 and extending the service life of the cables.

[0032] In this embodiment, the quick-release component 4 includes a support plate 10 fixed to the side of the bottom cover plate 3 away from the hinge. The support plate 10 is bent upward in an L-shape, and a shell 11 is horizontally fixed to the top of the support plate 10. A plug 12 is movably disposed inside the shell 11. The plug 12 is inserted into the side wall of the wire groove 1 to achieve the connection and fixation between the bottom cover plate 3 and the wire groove 1. A push-pull rod 13 is connected to the end of the plug 12 away from the wire groove 1. The push-pull rod 13 extends outside the shell 11 and is connected to a handle 14. By operating the handle 14, the push-pull rod 13 can be easily pushed or pulled, thereby driving the plug 12 to move inside the shell 11. In order to ensure that the plug 12 can be stably inserted into the side wall of the wire groove 1, a spring 15 is sleeved on the push-pull rod 13. The spring 15 is located inside the shell 11, and the elastic force of the spring 15 pushes the plug 12 into the side wall of the wire groove 1. When it is necessary to open the bottom cover plate 3, simply pull the handle 14. The push-pull rod 13 drives the insertion post 12 to move outward against the elastic force of the spring 15, so that the insertion post 12 is separated from the side wall of the wire trough 1. At this time, the bottom cover plate 3 can be rotated around the hinge point to open. When it is necessary to close the bottom cover plate 3, rotate the bottom cover plate 3 to fit against the bottom of the wire trough 1, release the handle 14, and the elastic force of the spring 15 pushes the insertion post 12 to move towards the side wall of the wire trough 1, so that the insertion post 12 is inserted into the side wall of the wire trough 1, thereby realizing the connection and fixation between the bottom cover plate 3 and the wire trough 1.

[0033] Working principle:

[0034] During installation, the hanger 2 is first fixed to the building or other supporting structure through the mounting holes on the mounting plate 7. Then, the cable tray 1 is connected to the hanger 2 through the connecting block 8 and tightened with the nut 9 to ensure the cable tray 1 is securely installed. When laying cables, the cables are placed on the support rods 5. Due to the even distribution of the support rods 5, the cables can be neatly arranged in the cable tray 1. The through holes 6 on the bottom cover plate 3 ensure air circulation, which is beneficial for cable ventilation and heat dissipation.

[0035] When it is necessary to inspect or maintain the cables in the cable tray 1, operate the handle 14 of the quick-release part 4 and pull the push-pull rod 13. This causes the insertion post 12 to move outward against the elastic force of the spring 15, disengaging from the side wall of the cable tray 1. At this time, the bottom cover plate 3 can be rotated open around the hinge point, allowing maintenance personnel to operate on the cables in the cable tray 1. After maintenance is completed, rotate the bottom cover plate 3 until it is flush with the bottom of the cable tray 1, release the handle 14, and the elastic force of the spring 15 pushes the insertion post 12 into the side wall of the cable tray 1, thus fixing the bottom cover plate 3 to the cable tray 1 and protecting the cables inside the cable tray 1.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
