Gantry crane full-size track linear control measurement method
The invention provides a gantry crane full-size track linear control measurement method, which comprises the following steps of lofting a track center line of a gantry crane on an expanded foundation, collecting elevation, leveling and pressing the track of the gantry crane according to the elevation, mounting a track prism of the gantry crane, and enabling a prism assembly to be positioned in the center of the track by a limiting sheet, a linear orientation method is adopted to set a station and define an assumed coordinate system of a portal crane track, a track prism is installed at a to-be-measured position of the portal crane track, and three-dimensional coordinates of the track prism in the assumed coordinate system are observed; and calculating and analyzing the span of the portal crane, the height difference between two vertical rails on the same cross section, and the bending and straightness of the portal crane in a vertical plane along the length direction through the three-dimensional coordinates. The method is simple and visual in data observation, and is favorable for guiding track linear control of the portal crane. By adopting the method, the full-size track linear control measurement problem of the gantry crane track can be effectively solved.
