Abstract
The invention discloses a tubular spline which comprises an inner sleeve and an outer sleeve, wherein both the inner sleeve and the outer sleeve adopt a hollow cylinder structure; a plurality of outer key bars which are uniformly arranged and extrude outwardly are arranged at the outer ring of the inner sleeve, and a plurality of inner key bars which are uniformly arranged and extrude inwardly are arranged at the inner ring of the outer sleeve; the inner sleeve is mounted at the inner part of the outer sleeve, the adjacent outer key bars and inner key bars are alternately arranged. By the arrangement, the tubular spline and a mud scraping mechanism with the tubular spline effectively solve the problem that a scraping arm and a scraping plate at the pool bottom of the mud scraping mechanism generate vertical displacement, enhance the mud scraping effect, and prolong the service life of equipment. Meanwhile, according to the tubular spline, the bearing weight of a truss is reduced, so that the power demand is reduced, and the energy conservation effect is significant. The tubular spline has the advantages of being simple in structure, low in processing and mounting precision requirement and less in equipment cost and meets various requirements of driving the mud scraping mechanism at the center of a sedimentation basin during sewage treatment.
