[0028] In a specific implementation manner, Figure 1-2As shown, the hanging rail includes a galvanized square tube 1, and a channel steel 6 extending along the length direction is fixed on the lower surface of the galvanized square tube 1, the opening of the channel steel 6 faces downward, and the two side edges of the opening are respectively connected to an inclined plate 7 extending in a gradually approaching direction, and the lower end of each inclined plate 7 is connected to an abutting horizontal plate 8 extending inwardly and approaching each other, and a constriction 9 is formed between the free ends of the two abutting horizontal plates 8, and the two wheel rims of the pulley 4 are respectively and one by one abutted to the two abutting horizontal plates 8, and the anti-fall brake 5 is connected to the pulley 4 through the constriction 9, and the channel steel 6, the two inclined plates 7 and the two abutting horizontal plates 8 surround the slideway 3.
[0029] The structural design of the hanging rail with a length can adapt to various complex high-altitude working environments (the hanging rail is easy to install and can be flexibly arranged according to actual needs to meet the anti-falling needs of different places). The high-altitude workers wear full-body safety belts, and the anti-fall brake 5 is hooked in the pulley 4. The hanging rail follows the high-altitude workers to move horizontally, ensuring that the anti-fall brake 5 is always directly above the workers, reducing the workers' sense of restraint; and the end flexible body and the internal flexible body are provided to prevent the rigid collision between different pulleys 4 from affecting the safety of different workers.
