The invention discloses a wheel diameter measuring instrument for locomotives and vehicles, which comprises an upright frame, the two sides of the frame are provided with measuring instrument positioning surfaces perpendicular to the horizontal line, and the lower part of the front side of the frame is provided with an angle Measuring instrument, the left and right sides of the upper part of the frame are symmetrically provided with positioning pins with the angle measuring instrument as the center, the positioning pins protrude from the measuring instrument positioning surface of the frame, and the upper end of the angle measuring instrument is connected to the machine. The front part of the frame is connected with a swing rod, and the swing rod is installed with a linear grating ruler through a slider that slides up and down along the swing rod and a linear grating ruler mounting seat, and the top of the linear grating ruler mounting seat protrudes from the frame. A measuring head arm is provided on the rear side of the measuring head arm, and a downward measuring head is provided at the tail end of the measuring head arm. The invention can solve the problem that the structure of the existing locomotive wheel is complex, and the space for measuring the diameter of the wheel without dropping the wheel is small and the problem of great difficulty in measurement is solved.
Description
technical field [0001] The invention relates to the technical field of manufacturing measuring instruments for locomotives, in particular to a measuring instrument for wheel diameters of locomotive wheels in the state of not being unloaded. Background technique [0002] With the increasing speed of railway operation year by year, in order to ensure the safety of railway transportation, the relevant railway departments have made stricter regulations on the wheel diameter difference of the same wheel set and the same bogie of different types of rolling stock. Perform non-drop wheel spin repairs, that is, perform rotary repairs without removing the wheelset. The increase in running speed makes the structure of the bogie more complex, and the space for measuring the wheel diameter without dropping the wheel is smaller, making the measurement more and more difficult. Therefore, it has become an important issue to improve the safety of railway transportation to use a smaller meas...
