Abstract

The invention discloses a sliding contact type signal acquisition device for rail detection, relating to the field of rail safety detection. The device comprises a bracket, a friction belt and a sensor, wherein the friction belt is arranged on the bracket, a flexible stable bed plate is arranged on the friction belt, and the sensor is arranged on the flexible stable bed plate. The friction belt is a polymer wear-resisting belt which is wear-resisting, heat-resistant, corrosion-resistant, and small in sliding friction coefficient. The friction belt is arranged an elastic compression plate, and a rotary pressure regulating shaft fixes the elastic compression plate on the bracket; and the sensor is arranged on the flexible stable bed plate sequentially through a magnetic compression piece and a magnetic installing seat. The magnetic compression piece and the magnetic installing seat are respectively made of a permanent magnet material or an electromagnet. According to the device disclosed by the invention, through the organic combination of components such as the rotary pressure regulating shaft, the elastic compression plate, the permanent magnet compression piece and the like, an effect that the friction belt is always closely attached to a measured rail surface in the whole moving process is achieved, thereby realizing the high-quality acquisition of vibration signals of steel rails.

Description

technical field [0001] The invention relates to the technical field of track safety detection, in particular to a sliding contact signal acquisition device for track detection. Background technique [0002] To pick up rail vibration signals in a moving state, the current main method is to place sensors (contact sensors or non-contact sensors) on rolling mobile devices, such as on the wheel axle, and use the vibration signal on the wheel axle to approximately replace The vibration signal of the rail. The vibration signal obtained by placing the sensor on the rolling mobile device tends to contain uncontrollable interference signals from the vibration of the rolling device itself, making the measurement data inaccurate. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is: how to provide a sliding contact signal acquisition device for rail detection, so as to eliminate or reduce inter...
