The invention relates to a sealing device and an ultrasonic wheel detector. The sealing device comprises a sealing block and a plate shaft. The plate shaft is provided with a plate shaft through holewhich penetrates through the two ends of the plate shaft. The sealing block is provided with multiple sealing block wire passage holes. At least one end of the plate shaft through hole is provided with an inner conical surface. The diameter of the inner conical surface gradually increases from the middle of the plate shaft to the end of the plate shaft. At least one sealing block is arranged. Thesealing block is provided with an outer conical surface matched with the inner conical surface. The sealing block is in interference fit with the corresponding end of the plate shaft through hole. Wire cables are in interference fit with the sealing block wire passage holes. The sealing device and the ultrasonic wheel detector have the beneficial effects that the problems in sealing of coupling fluid of the ultrasonic wheel detector are solved, the wheel detector can be conveniently and quickly detached or installed, the sealing performance is improved, operation is convenient and quick to carry out, the time for filling glue to dry is shortened, and the assembly efficiency of the wheel detector is improved; and the service life of the wheel detector can be effectively prolonged, the problems of gas intake and interior pressure reduction of a wheel detector caused by fluid leakage happen less, and the detection quality of the wheel detector is improved.

    本发明涉及一种密封装置及超声波探轮,密封装置包括密封块和盘轴,盘轴具有贯穿其两端的盘轴通孔,密封块具有多个用于穿设线缆的密封块过线孔,盘轴通孔的至少一端具有内锥面,内锥面的直径由盘轴中部向端部逐渐增加,密封块设置至少一个,并具有与内锥面相适配的外锥面,密封块与盘轴通孔对应的端部过盈配合,且线缆与密封块过线孔过盈配合。本发明的有益效果是:针对超声波探轮的耦合液密封问题,能够方便快速的拆装探轮,改善密封性能,操作方便快捷,减少灌胶需要的干燥时间,提高探轮的组装效率,同时可有效提高探轮使用寿命,减少因探轮漏液而造成的探轮进气、内部压力降低等问题,提高探轮的检测质量。
