when the limit detection device (1) is not operated, the driving motor (15) controls a thrust rod of the linear driving mechanism (13) to retract, the thrust rod of the linear driving mechanism (13) retracts and pulls the mounting frame (10) to retract, and the guide sliding block (16) is matched with the guide sliding rail (12) to guide and position the motion process; the compression rod (4) pulls the switch door (5) to close towards the inner side, after the compression rod (4) retracts to the set position, the external pressure of the compression rod (4) is cancelled and restored to the free length, and the mounting rack (10) drives the detection radar (9) to continue to retract; the compression rod (4) pulls the switch door (5) to be continuously closed, and when the mounting frame (10) retracts to the designated position, the compression rod (4) pulls the switch door (5) to be completely closed, and the detection radar (9) retracts to be located in a box body (6) of a cab (17).
13. The method of operating a railway clearance inspection apparatus of claim 11 or 12, wherein: the extension or retraction displacement of the detection module (3) is controlled by an operator in a cab (17) through a stroke handle (11) arranged on the outer side of the box body (6), so that the detection radar (9) can be started or stopped at any position in the stroke of the linear driving mechanism (13).
