In this embodiment, the adjustment rod 7 is movably connected to both vertical side plates 6. In other embodiments, it can also be movably connected to one vertical side plate 6 and fixedly connected to the other vertical side plate 6. In this embodiment, the distance between the two vertical side plates 6 is adjustable and can be applicable to beams of different widths. The plurality of moving wheels 2 that can be placed on the beam can drive the safety belt suspension device to move along the length direction of the beam, facilitating quick movement between different construction locations along the length direction of the beam, and can reduce the time for reinstalling the safety belt after the construction location is changed. In this embodiment, the safety belt suspension device is installed on the lower flange of the H-shaped steel beam 11.
