[0002] In subway construction, signal machines are an important part of the signal interlocking system. Their installation height and limits must meet certain requirements. If the height does not meet the requirements, it will affect the train's reception of the signal transmitted by the signal machine, and if the limits do not meet the requirements, it will directly affect the train's operation. Since the normal installation of signal machines on poles in tunnels will result in limits not meeting the requirements, wall-mounted signal machines need to be directly driven into the inner wall of the tunnel with expansion bolts, and then installed inside. The entire installation process is difficult and complicated. Considering that two vertical external hanging channels will be installed every 1.5 meters in the subway section tunnel, an integrated installation device is designed for the signal machine using the external hanging channel to facilitate the installation of signal machines and boxes in the section tunnel.
