The invention discloses a ballastless track slab quality detection device, which comprises a rail plate body, a rail, a trolley and a driving mechanism. The rail is erected on the concrete-poured rail plate body, and the quality of the rail plate body is detected through the trolley arranged on the rail and a vehicle-mounted detection system on the trolley. The detection system comprises a springback hammer and a sound sensor, the springback hammer and the sound sensor are connected with a fixing block, the fixing block is connected with an adjusting mechanism, and the other end of the adjusting mechanism is arranged on the trolley body. The rail trolley is arranged and matched with the adjusting mechanism and the detection system and can run on the rail, bridge knocking detection can be carried out without dead corners, a detection result is obtained through analysis, and the detection rate is increased. Through feature extraction and data analysis of the sound wave signals, the accuracy of void and fracture judgment is improved, and the safety of rail transit operation is improved.
