[0002] Cable trays are divided into trough, tray, ladder, grid and other structures, and are composed of brackets, brackets and installation accessories. The cable trays in buildings can be erected independently or laid on various buildings (structures) and pipe gallery brackets. They should have the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance. All parts need to be galvanized and installed in the open-air cable trays outside the building.

[0003] The main causes of cable tray fires are overload, short circuit, excessive contact resistance and external heat sources. Under fault conditions such as short circuit, local overheating and external heat, the insulation material resistance decreases, loses insulation ability and even burns, causing fires.

[0004] In the related art, the cable tray is based on its own structure, and the cables are attached to a supported building or to an independent supporting cable, which can act as a frame on the cable. However, when some existing single-support cable trays are in use, the support arms are mainly connected to the installation frame by bolts, which makes it impossible to flexibly adjust the spacing between the support arms. During the adjustment process, the bolts need to be disassembled and reinstalled, which takes a long time. In addition, this connection method cannot quickly replace the support arm when the support arm is damaged.

[0005] Therefore, it is necessary to provide a cable tray with an early warning structure to solve the above technical problems. Utility Model Content

[0034] The smoke alarm 12 and the sound and light alarm 13 are common devices in the existing market, and the specific models can be installed independently according to the place of use and usage requirements.

[0035] Two sliding blocks 4 are slidably disposed on the inner sides of the two support arms 35 , respectively. The inner sides of the two support arms 35 are each provided with a sliding groove 5 used in conjunction with the sliding blocks 4 . The tops of the four sliding blocks 4 are each provided with a threaded rod 6 .

[0036] The sliding groove 5 is used in conjunction with the sliding block 4 to allow the sliding block 4 to slide left and right. The setting of the threaded rod 6 can fix the bridge box (first set a pressure plate on the surface of the threaded rod 6, and then use the threaded sleeve to press down and fix the bridge box through the pressure plate)

[0037] Two connecting frames 7 are arranged on the surface of the mounting frame 1 , bolts 8 are arranged on the inner sides of the mounting frame 1 and the two connecting frames 7 , and nuts 9 are arranged on the surfaces of the two bolts 8 .

[0039] A mounting hole 10 for use with two bolts 8 is provided on the inner side of the mounting frame 1 , and two expansion bolts 11 are provided on the inner sides of the two connecting frames 7 .

[0040] The bolts 8 are installed by setting the mounting holes 10 , and after holes are opened on the wall, the connecting frame 7 and the mounting frame 1 are installed by the expansion bolts 11 .

[0041] The working principle of a cable tray with an early warning structure provided by the utility model is as follows:

[0042] Step 1: When in use, first connect the mounting frame 1 and the connecting frame 7 by means of bolts 8 and nuts 9, then fix the mounting frame 1 on the wall by means of expansion bolts 11, then insert the connecting block 31 into the adjusting block 22, and connect the adjusting block 22 and the connecting block 31 by means of the insert rod 32, thereby completing the installation of the support arm 35;

[0043] Step 2: The threaded screw 21 is driven to rotate by rotating the knob 24. The rotation of the threaded screw 21 drives the two adjustment blocks 22 to move to opposite sides. The movement of the two adjustment blocks 22 drives the two support arms 35 to move to opposite sides, thereby adjusting the distance between the two support arms 35.

[0044] Compared with the related art, the cable tray with early warning structure provided by the utility model has the following beneficial effects:

[0045] The two adjusting blocks 22 are driven to move to opposite sides by the rotation of the threaded screw 21, and the movement of the two adjusting blocks 22 drives the two supporting arms 35 to move to opposite sides, thereby adjusting the distance between the two supporting arms 35.
