The ultrasonic detection wheel is mainly composed of a sealing bearing structure, a shaft connecting structure, a wheel skin and coupling liquid. The detection wheel comprises a left shaft 1, a right shaft 2, bearing dust covers 3 (one left and right), hole clamps 4 (one left and right), bearings 5 (one left and right), wheel leather pressing plates 6 (one left and right), a left wheel disc 7, a right wheel disc 8, rotary spring seals 9 (one left and right), rotary spring seal base pressing plates 10 (one left and right), a two-shaft connecting frame 11, shaft clamps 12 (one left and right) and a wheel leather 13. A sealing mode of rotary spring sealing is adopted, a sealing mode of magnetic suction sealing in an existing detection wheel is improved, a rotary sealing mode of rotary spring sealing is adopted, the better sealing effect can be achieved, the manufacturing cost is lower, and the matching requirement is lowered.
