Embodiment Construction

[0018] See attached Figure 1-4 , a large-scale freighter floor guide rail installation device, comprising a base 3, a beam 4, a laser ranging sensor 6, the base 3 is an inverted T-shaped structure, the beam 4 is a straight beam structure, and the bottom plate of the base 3 is provided with a A row of pin holes 7 and an oblong hole 8 are provided at the other end. A crossbeam positioning hole 9 and a crossbeam passing hole 11 are provided on the column perpendicular to the bottom plate on the base 3. A sensor installation positioning hole for accurately calibrated dimensions is provided on the crossbeam 4. The crossbeam 4 is installed on the base column, and is perpendicular to the longitudinal centerline of the bottom plate, and four laser ranging sensors 6 are symmetrically installed in the positioning holes on the left and right sides of the beam 4

[0019] The crossbeam 4 is equipped with a crossbeam stopper 10 and a sensor fixing part 12. When the crossbeam 4 is installed...

Abstract

The invention provides a large-scale freighter floor guide rail installation device and an installation method. The device includes a base, a beam and a laser distance measuring sensor. When in use, first install the base on the installation reference hole of the floor guide rail of the aircraft cargo warehouse. After the installation is completed, the laser ranging sensors on both sides can measure the distance from the floor guide rails on both sides in real time and record it automatically. One measuring position can measure 4 data at the same time to judge whether it meets the installation requirements of the floor guide rail. The invention has a compact and reasonable structure, and solves the difficult problem that the installation accuracy of the floor guide rail of a large freighter cannot be guaranteed and detected.

Description

technical field [0001] The application relates to the technical field of aircraft assembly and manufacturing, in particular to a method for installing floor guide rails of large cargo aircraft. Background technique [0002] There are 4 floor guide rails on the floor of the cabin of a large cargo aircraft, including 2 main floor guide rails and 2 auxiliary floor guide rails (such as figure 1 As shown), every two floor guide rails are set to realize the guiding function. The installation of the floor guide rails is a very important process. The installation accuracy of the floor guide rails is used to ensure that the movement of the goods between the floor guide rails will not be stuck, and the parallelism of the floor guide rails must be within the scope of the design requirements. Existing measurement methods such as laser trackers Or the laser interferometer is limited by the narrow space and lack of a suitable size and stable plane, and the installation accuracy of the fl...
