The invention relates to a level and gauge calibration device for a track inspection vehicle. The level and gauge calibration device is used for calibrating the track inspection vehicle before the track inspection vehicle detects a track. The device comprises a calibration ruler; the calibration ruler comprises a connecting piece; two clamping plates are symmetrically arranged at the two ends of the connecting piece, and a horizontal calibration bubble and a folding positioning assembly are arranged on the connecting piece. The folding positioning assembly comprises a hinged support, a vertical rod and a horizontal rod; the hinged support is fixed on the connecting piece; the horizontal rod is hinged to the hinged support and can rotate around the hinged support on the horizontal plane. A first storage groove matched with the vertical rod is formed in the horizontal rod; the vertical rod is hinged to the inner side wall of the first containing groove and can rotate around the horizontal rod on the vertical face. During calibration, the connecting piece is lapped on the track through the clamping plate, the horizontal rod is parallel to the track, the vertical rod is perpendicular to the horizontal rod and makes contact with the side wall of a track inspection beam of the track inspection vehicle, and at the moment, the calibration ruler is located under the track inspection beam. Compared with the prior art, the device has the advantages of being simple and convenient to operate, high in efficiency, convenient to carry, time-saving and labor-saving and the like.
