This utility model provides a safety rope fixing device, belonging to the technical field of high-altitude operation safety protection equipment. This device, through the combination of a hollow slide rail and a spherical slider, and the design of a maintenance channel on the slide rail assembly, solves the problems of high friction during movement of the movable safety rope anchoring part in existing technologies, resulting in inflexible safety rope movement, inability to meet the needs of frequent anchor point movements, inconvenient maintenance, and increased risk of safety accidents. The device includes a slide rail assembly and a sliding module. The sliding module is slidably mounted on the slide rail assembly, and the safety rope is fixed to the sliding module. The slide rail assembly is composed of a hollow tube with a continuous groove along its length. The sliding module includes a spherical slider and a connecting part. The spherical slider is disposed inside the slide rail assembly, and its diameter is smaller than the inner diameter of the slide rail assembly but larger than the width of the groove. The connecting part connects the spherical slider and the safety rope. The slide rail assembly also has a maintenance channel, through which the spherical slider can be removed.
