The invention discloses a tension maintaining device, which comprises a first gear and a second gear which are arranged on a same gear shaft in a sleeving manner; the first gear is fixedly arranged on the gear shaft and is connected with a gear drive system of a steel wire rope guide wheel; two ends of the gear shaft are provided with rolling bearings; the second gear is arranged on the gear shaft by virtue of a one-way bearing in a sleeving manner; a bushing is arranged between the second gear and the one-way bearing; the second gear is connected with a gear drive system by virtue of which a motor drives a drum; the end faces on two sides of the second gear are fixedly provided with static friction disks; the static friction disks are correspondingly provided with kinetic friction disks in a pressing manner; the kinetic friction disks are fixedly connected with the outer ring of the one-way bearing in a sleeving manner in the circumferential direction. According the tension maintaining device disclosed by the invention, a pure mechanical structure is adopted for realizing the constant tension of a lifting steel wire rope, the structure is simple, the design is ingenious, the friction disks adopt wet paper base friction materials, high reliability is realized, long service life is guaranteed, and the tension can be adjusted by virtue of the pressing force of the friction disks.
