description The utility model provides an interval error measuring instrument for wheel type tracks, which comprises a roller 1 and a roller 2 both provided with wheel rims. The roller 1 is provided with a sliding shaft sleeve. Inside the sliding shaft sleeve, a compression spring is arranged close to the roller 1, and a sliding shaft is arranged close to the compression spring. One end of the sliding shaft is sleeved inside the sliding shaft sleeve. The other end of the sliding shaft is arranged on the roller 2. A wedge-shaped block is arranged on the sliding shaft. The sliding shaft sleeve is provided with an elongated aperture corresponding to the position of the wedge-shaped block. The wedge-shaped block extends out of the elongated aperture. A piston is arranged above the wedge-shaped block. The lower surface of the piston is provided with a wedge-shaped sliding groove matched with the wedge-shaped block. A piston return spring is arranged above the piston. A piston cylinder is sleeved outside the piston. The piston cylinder is fixedly arranged on the sliding shaft sleeve through a connecting piece. The piston cylinder is provided with a transparent graduated tube in communication with the interior of the piston cylinder. A pressing handle is arranged outside the sliding shaft sleeve. By means of the measuring instrument, the interval error of tracks can be quickly, accurately and continuously measured.
