The invention provides a swing device and a rail detector, the swing device is applied to the rail detector, the rail detector comprises an auxiliary girder, the swing device comprises a device body, a swing structure and a connecting structure, the swing structure is connected with the device body, and the connecting structure is connected with the swing structure and the auxiliary girder. The swing structure comprises a swing part and swing limiting parts arranged at the upper end and the lower end of the swing part respectively, and the swing limiting parts rotate relative to the central axis of the swing part so that the auxiliary girder can swing within the preset angle range. By arranging the swing piece and the swing limiting piece, and enabling the swing limiting piece to rotate relative to the central axis of the swing piece, a small-angle swing function of the auxiliary girder is provided, so that the auxiliary girder can swing around the central axis within a certain range, and it is guaranteed that the track detector always walks on the upper surface of a track; therefore, it is guaranteed that the track detector can keep the measuring posture in the rapid measuring state, and meanwhile the distance between the measuring wheels between the girders is kept unchanged.

    本发明提供一种摆动装置及轨检仪,该摆动装置应用于轨检仪,轨检仪包括辅助大梁,摆动装置包括装置主体、摆动结构及连接结构,摆动结构与装置主体相连接,连接结构分别连接摆动结构和辅助大梁,摆动结构包括摆动件以及分设于摆动件的上下两端的摆动限位件,摆动限位件相对于摆动件的中轴线旋转,以使辅助大梁进行预设角度范围的摆动。本发明通过设置摆动件和摆动限位件,并使得摆动限位件相对于摆动件的中轴线旋转,以提供辅助大梁的小角度摆动的功能,使得辅助大梁能够围绕中轴线进行一定范围的摆动,保证轨检仪的行走始终落在轨道的上表面,从而保证轨检仪在快速测量状态既能保持测量姿态,也同时保持大梁之间的测量轮间距不变。
