Technical Field

[0006]

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

[0002] A cable tray is a device used to inductively protect cables. Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, cross arms and installation accessories. Cable trays have the advantages of light structure, high strength, low cost, simple construction, flexible wiring, accurate installation, beautiful appearance, etc., and bring convenience for future technical improvement, cable expansion, maintenance and repair; they are widely used in departments such as electronics, machinery, light industry, textile, metallurgy, electric power, etc. and are commonly used cable laying devices for power supply cables and control cables in high-rise large buildings.

[0003] However, when the traditional cable tray is maintained at a certain place, since its cover body is often an integral structure, it is necessary to open it as a whole, and all the cables inside the tray are exposed for maintenance, which makes the maintenance not only troublesome, but the overly exposed cables are also prone to safety problems; in addition, the traditional cable tray often lacks a structure for restraining and fixing the cables, and the complex and stacked cables also cause great difficulties for maintenance.

[0022] Embodiment

[0023] As Figures 1-3 shown

[0024] A cable tray convenient for maintenance includes a tray shell 1 in the shape of "冖". Four support arms 7 are arranged in a matrix array at the upper end of the tray shell 1 for fixedly connecting with the external wall top. Specifically, the support arm 7 has a "匚" - shaped structure, which facilitates the fixation of both ends thereof to the wall top and the tray shell 1 respectively by screws, realizing ceiling installation. Preferably, the support arm 7 can also have an "I" - shaped structure. With this solution, the orientation does not need to be considered during use, which is more convenient and fast.

[0025] A number of groups of cable fixing components 6 are arranged side - by - side front - to - back inside the tray shell 1 for axially segment - fixing a long cable inside the tray shell 1.

[0026] Specifically, the cable fixing component 6 includes a cross - bar 63. Three rubber sleeve rings 62 made of rubber are sleeved on the cross - bar 63. Further, in order to prevent the rubber sleeve rings 62 from sliding randomly on the cross - bar 63, the rubber sleeve rings 62 are sleeved on the cross - bar 63 in a tight - fitting state and can be toggled by an external force. A connecting rod 61 is provided at the lower end of each rubber sleeve ring 62. A mounting hole is opened at the lower end of the connecting rod 61, and a tie - strap 64 is穿设在 the mounting hole for bundling and fixing the cable on the rubber sleeve ring 62.

[0027] With this solution, the rubber material has a large friction coefficient and good anti - slip effect. The tight - fitting rubber sleeve rings 62 not only achieve the fixing effect but also can be toggled by an external force to adjust the spacing. Therefore, complex functions are achieved through a simple structure, which is both convenient to use and reduces production costs. In addition, setting multiple rubber sleeve rings 62 and tie - straps 64 can also fix and adjust multiple bundles of cables respectively, achieving a better inductive fixing effect.

[0028] Preferably, the number of cable ties 64 can also be selected according to actual needs, and each cable tie 64 is connected to the cross bar 63 through a connecting rod 61 and a rubber ring 62.

[0029] The lower end of the bridge housing 1 is slidably connected to a sliding cover 2, on which a plurality of inspection windows 22 are arranged side by side in front and back, and each inspection window 22 is provided with an inspection sliding cover 5.

[0030] Through this solution, after a number of inspection windows 22 are set on the sliding cover 2, it is not necessary to remove the entire sliding cover 2 to inspect the cables in the bridge shell 1 during maintenance. It is only necessary to open the inspection sliding cover 5 at the corresponding position to carry out maintenance through the inspection window 22, which makes maintenance more convenient and reduces large-scale disassembly during maintenance, thereby improving maintenance efficiency and reducing the risk of accidents caused by excessive exposure of cables.

[0031] Specifically, the sliding cover 2 is plate-shaped, and its left and right ends are folded back to form a sliding groove 21. The lower ends of the left and right sides of the bridge shell 1 are provided with connecting parts 11 matching the sliding groove 21. Through this scheme, the sliding cover 2 can be slidably connected to the bridge shell 1, which is convenient for disassembly and installation; at the same time, the front and rear ends of the bridge shell 1 and the sliding cover 2 are connected by bolts on both sides to prevent them from sliding independently, thereby improving the stability of use.

[0032] Furthermore, a U-shaped slot 4 is provided on the inspection window 22, and the inspection slide cover 5 is inserted into the slot 4 from one side by interference fit, and the slide cover 5 is also provided with a handle 51 for facilitating its removal.

[0033] Through this solution, the inspection sliding cover 5 can be fixed and covered on the inspection window 22, playing a good isolation role.

[0034] The working mode of this device:

[0035] When it is necessary to organize the cables, the cables are passed through the bridge shell 1 and through several cable ties 64 located on the same straight line in the bridge shell 1. After the cables are inserted, the cable ties 64 are tightened. Thus, several cables are bundled into a cable bundle and fixed on the crossbar 63. The position of the cable bundle can be adjusted by toggling the rubber ring 62 to facilitate subsequent cable organization. When other cables need to be organized, the same operation can be performed.

[0036] When a certain part of the cable needs to be inspected, it is only necessary to drag open the inspection slide 5 at the corresponding position to open the inspection window 22 to inspect the cable in the bridge housing 1. After the inspection is completed, push the inspection slide 5 in to close it.

[0037] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
