Subway cable ducts will be installed in station platforms, passages and corridors, tunnels and underground passages, etc. During the installation process, the subway cable duct needs to be fixed with a support device.

[0003] After searching, a Chinese patent with authorization number CN 216086092 U discloses an adjustable bus duct support device, which can control the first anti-static PC board to rise or fall by twisting the rotation direction of the second threaded rod so that the top of the bus duct is against the bottom of the second anti-static PC board, reducing the back-and-forth shaking and increasing the stability of the bus duct. By using it in conjunction with the first threaded rod, the guide rod and the connecting plate, it can be adjusted according to the site height and customer needs. However, the device is supported by the first threaded rod and the guide rod in the vertical direction and is prone to shaking. Although the prior art can be reinforced by adding an anti-sway frame, it is inconvenient to add the anti-sway frame again. Therefore, a support device for a subway line duct is proposed to solve the above problem. Utility Model Content
