[0013] In the following description, embodiments of the large-span cable tray support crossarm of this utility model will be described with reference to the accompanying drawings.

[0014] Figure 1-4This invention illustrates a crossarm supporting a large-span cable tray according to an embodiment of the present invention. It includes two square steel beams (1-2) supported between two I-beams (1) within a building. Two symmetrical square steel beams (2-3) are welded between the two square steel beams (1-2). A cable tray (4) is placed on top of the two square steel beams (1-2). Angle brackets (6) are welded to the surface of the cable tray (4), and their bottoms are welded to the square steel beams (1-2). The angle brackets (6) enhance the stability of the cable tray (4) and the square steel beams (1-2), ensuring the stability of the cable tray (4) above the crossarm composed of the square steel beams (1-2) and the square steel beams (2-3). Two symmetrical adjustable mounting pieces (5) are provided between the square steel beams (1-2) and the I-beams (1-2). Mounting component 5 includes a mounting plate 51 installed at the bottom of the I-beam support beam 1. The mounting plate 51 is fixedly installed to the I-beam support beam 1 by four bolts. An angle steel 52 is welded to the surface of the square steel 1 2. An expansion joint is provided between the angle steel 52 and the mounting plate 51. The expansion joint includes connectors 53 welded to the top of the angle steel 52 and the bottom of the mounting plate 51 respectively. A threaded post 54 is rotatably connected to the top of the bottom connector 53 via a pivot. A sleeve 55 is slidably connected to the surface of the threaded post 54. The top of the sleeve 55 is rotatably connected to the top connector 53 via a pivot. A threaded sleeve 56 is rotatably connected to the surface of the sleeve 55. The internal thread of the threaded sleeve 56 is connected to the surface of the threaded post 54.

[0015] Working principle: When using this utility model, according to the distance between the two I-shaped support beams 1, the threaded sleeve 56 is manually operated to make the threaded column 54 extend and retract within the cavity of the sleeve 55 to adjust the length. The length of the adjustable mounting parts 5 on both sides of the crossarm composed of square steel 1 2 and square steel 2 3 can be adapted to the distance between the two I-shaped support beams 1. The mounting plate 51 is then installed on the I-shaped support beam 1 with bolts. The cable tray passes through the crossarm composed of square steel 1 2 and square steel 2 3. The cable tray 4 is installed with the crossarm through the angle bracket 6. When it is necessary to adjust the height of square steel 2 3, the threaded sleeve 56 can be rotated to adjust the height of the crossarm, thereby adjusting the height of the cable tray 4.

[0016] In summary, this large-span cable tray support crossarm, through the adjustability of the telescopic components on the adjustable mounting piece 5, allows the mounting plates 51 at both ends of the adjustable mounting piece 5 to be adapted to the distance between the two I-beam support beams 1 and installed. This makes the height of the crossarm composed of square steel 1 2 and square steel 2 3 connected to the adjustable mounting piece 5 controllable and highly adaptable to different installation scenarios. This achieves the goal of using the support crossarm to install large-span cable trays, ensuring the stability of the cable tray support, and the telescopic installation structure of the support crossarm ensures its adaptability to different installation scenarios.
