Abstract

The invention provides a large-scale air freighter guide rail installing device and an installing method. The device comprises a base, a cross beam and laser distance measuring sensors. When the large-scale air freighter guide rail installing device is in use, firstly, the base is installed to mounting reference holes of floor guide rails of a freight house of an aircraft, and after installation is completed, the laser distance measuring sensors at the two sides can measure the distance of floor guide rails at the two sides in real time and automatically record the distance. Four pieces of data can be measured simultaneously from one measuring position, and whether the installing requirement of the floor guide rails is met or not is judged. The large-scale air freighter guide rail installing device is compact and reasonable in structure, and the problems are solved that the installing precision of a large-scale air freighter guide rail cannot be guaranteed and detected.

Description

technical field [0001] The present application relates to the technical field of aircraft assembly and manufacturing, in particular to a large cargo aircraft floor guide rail installation device and installation method. 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 insta...
