A displacement propulsion mechanism suitable for use in a railway wheel type structure as claimed in claim 1, wherein: firstly, moving a bogie to a working position, ensuring that a roller is positioned near the initial position of a friction displacement positioning assembly, and conveniently aligning the central position of the roller; then, starting a program switch of the equipment to work, aligning the roller through two groups of photoelectric sensors arranged on a friction roller seat, and driving a lifting assembly and a friction displacement positioning assembly to move in a rail direction through a translation pushing assembly when the judgment position deviates to one side until the judgment position of the sensors is aligned; after the alignment work is finished, the lifting assembly starts to work, and after the friction displacement positioning assembly is jacked up, the locking cylinder is controlled by a circuit to enable the locking pin to be inserted into the locking circular hole in the right-angle hanging plate to finish locking; at the moment, the friction wheel on the friction wheel seat is in contact with the front side and the rear side of the roller on the track, and the roller moves along the axial direction along with the friction displacement positioning assembly, so that the roller moves along with the friction transmission; after the roller moves to a target station, a camera at the manipulator end of the robot is controlled by the robot to photograph a measured position, a corresponding computer system reads and analyzes an image obtained by photographing to obtain the difference between an actual photographed image and a standard best effect image, namely distance control, the adjustment of the focal distance between the camera and a measured object is realized by driving the roller to move along the axial direction, and the determination of the best photographing working position is finally realized by circulating photographing feedback;
after the roller moves to the optimal shooting working position, corresponding shooting measurement is carried out, the friction displacement positioning assembly is continuously controlled to move along the axial direction, the roller is moved to the next measurement working position through friction transmission, and the steps are repeated to realize the photogrammetry work of the measurement working position.
3. A displacement propulsion mechanism suitable for use in a railway wheel type structure as claimed in claim 2, wherein: after all the working positions are measured, the locking cylinder is controlled by a circuit to enable the locking pin to be pulled out of the locking round hole in the right-angle hanging plate to complete unlocking, and the lifting assembly is used for reducing friction and displacing the positioning assembly to the original lowest position; at this time, the whole working process of the displacement propulsion mechanism is completed, so that the next assembly or measurement work can be started.
4. A displacement propulsion mechanism suitable for use in a railway wheel type structure as claimed in claim 1, 2 or 3, wherein: the running stroke range is 0m-4 m.
