Measuring device for perpendicularity and planeness of vertical type rail and measuring method thereof

The invention discloses a measuring device for perpendicularity and planeness of a vertical type rail and a measuring method thereof, and belongs to the technical field of measurement of the perpendicularity and planeness. The measuring device for the perpendicularity and planeness of the vertical type rail comprises a measuring unit and a positioning unit. The measuring unit comprises a total station or a theodolite or a gradienter. The positioning unit comprises a measuring rod, a connecting piece and a magnetic base. The measuring rod is fixed to the upper surface of the magnetic base through the connecting piece. The planeness of the bottom face of the magnetic base is smaller than 0.005 mm. The measuring method includes the steps of assembling, absorbing, zero returning, measuring unit position selection, eyepiece observation, adjusting, measuring point replacement and rail debugging. According to the device and the method, the measuring unit and the positioning unit are arranged in a separated mode, the positioning unit achieves accurate positioning through the measuring rod and attraction by the magnetic, and the purpose of accurate measuring of the perpendicularity and planeness in any space without being affected by external factors can be achieved.
