This utility model relates to the field of yarn feeder technology, and discloses a guide roller assembly and a yarn feeder for a high-speed, multi-path yarn feeder. The guide roller assembly includes a bearing B, a bearing A, a roller, a mandrel, an elastic washer, and fixing screws. Bearing B is a floating bearing. An O-ring is added to the mandrel at the location of the floating bearing B. By changing the depth of the groove of the O-ring and the matching of the O-ring wire diameter, suitable friction can be obtained, stabilizing the static state of the inner ring of the floating bearing B, avoiding wear between the inner ring of bearing B and the mandrel, and ensuring that the bearing is always in a normal working state. This guide roller assembly has a simple structure and stable improvement effect.

The invention discloses a bridge cable detection robot control method, a bridge cable detection robot comprises an outer regular octagonal prism frame and an inner octagonal reinforcing frame, the top and the bottom of the outer regular octagonal prism frame are respectively provided with a front moving wheel set and a rear moving wheel set, the front moving wheel set comprises four H-shaped swing arms hinged to the outer regular octagonal prism frame, and the rear moving wheel set comprises four H-shaped swing arms hinged to the outer regular octagonal prism frame. A swing arm telescopic rod is hinged between the middle of each H-shaped swing arm and the inner octagonal reinforcing frame. Mecanum wheels are arranged on the sides, away from the hinged ends, of the H-shaped swing arms. The sensor assembly comprises a nine-axis attitude sensor and a pressure sensor for acquiring the pressure of the telescopic rod of the swing arm. The control method comprises the control steps of S1 to S7. The bridge inhaul cable detection robot is provided with a specific posture control algorithm, the stability of the bridge inhaul cable detection robot is greatly enhanced, the bridge inhaul cable detection robot can stably crawl on the inhaul cable in a complex environment, and the safety of the detection process is effectively guaranteed.

The utility model relates to the technical field of traditional Chinese medicine cleaning, in particular to cleaning equipment for traditional Chinese medicine decoction piece production, which comprises a support, an arched protective cover is arranged above a support body, and a plurality of water spray pipes are arranged on the inner wall of the top end of the protective cover; a driving shaft and a driven shaft are symmetrically arranged on the two sides of the top of the support through bearing seats respectively, a first rolling ring and a second rolling ring are arranged at the front end and the rear end of a driving shaft body and the front end and the rear end of a driven shaft body respectively, U-shaped grooves are formed in the first rolling ring and the second rolling ring, and rotating wheels matched with the U-shaped grooves are arranged on the driving shaft and the driven shaft in a penetrating mode. A plurality of brush plates are arranged between the first rolling ring and the second rolling ring, bristles are arranged on the inner surfaces of brush plate bodies, and the bristles brush traditional Chinese medicinal materials through rotation; the cleaning equipment can avoid damage to skins of rhizome traditional Chinese medicinal materials caused by collision or extrusion, and meanwhile, continuous cleaning can be realized, so that the labor intensity of workers is reduced.
