[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the specific implementation methods of the present invention will be described in detail below with reference to the technical solution.
[0021] The present invention provides a cockpit clamping and fixing tool for repairing a damaged aircraft, which belongs to a component of the damaged aircraft repair tool. The bottom of the damaged aircraft repair tool is a ground platform, and the cockpit clamping and fixing tool is installed on the ground platform at the bottom of the damaged aircraft repair tool. Figure 1 The cockpit clamping and fixing tool is a three-axis movable gantry structure, including a gantry frame 1, an X-axis adjustment beam 3, a Y-axis adjustment beam 2, a hoisting mechanism 4 and a protective sling 5. After the assembly is installed, Figure 2 and Figure 3 As shown; the overall inner dimensions of the gantry frame 1 are (3800×3000×4600) mm, and it is made of Q235A / (160×160×12) mm square steel pipes. Each gantry column is connected to the crossbeam by bolts. The entire frame is a detachable structure for easy transportation. A Q235A sheet with a thickness of δ20 mm is installed at the bottom of the gantry column as a bottom plate for fixed connection with the ground platform. Four reinforcing rib plates made of Q235A plates with a thickness of δ12 mm are welded between each bottom plate and the gantry column, such as Figure 4As shown, multiple φ5mm process holes of different heights are processed on the top of the gantry column (drilling is performed according to the actual size of the bolts during installation). After the gantry frame 1 is built, inclined braces can be installed according to the stability. One end of the inclined braces is screwed to the gantry column, and the other end is fastened to the ground platform; there are two Y-axis adjustment beams 2, which are installed in parallel between the gantry columns. The two are made of rectangular steel pipes of Q235A / (200×150×8)mm, and the flange structures made of Q235A / δ12mm steel plates at both ends are fixedly connected to the gantry columns through process holes. By connecting with process holes of different heights, the height along the Z-axis direction can be adjusted according to the actual position requirements. According to the actual working requirements, multiple φ5mm installation holes are prefabricated in the horizontal direction on the Y-axis adjustment beam 2; there are two X-axis adjustment beams 3, which are installed in parallel between the two Y-axis adjustment beams 2 The X-axis adjustment beam 3 and the Y-axis adjustment beam 2 are connected to each other through mounting holes. The mounting position of the Y-axis adjustment beam 2 can be adjusted by connecting different mounting holes to form an adjustment mechanism in the XY-axis plane. The X-axis adjustment beam 3 and the Y-axis adjustment beam 2 together form an XYZ three-dimensional mobile structure. The X-axis adjustment beam 3 is prefabricated with a plurality of φ5mm process holes in the horizontal direction according to the actual working requirements for the installation of the hoisting mechanism 4. The hoisting mechanism 4 is provided with a plurality of them, and the materials are all Q235A steel. The top of the hoisting mechanism 4 is fixedly installed on the process hole of the X-axis adjustment beam 3. The installation position of the X-axis adjustment beam 3 can be adjusted by connecting process holes at different positions. The bottom of the hoisting mechanism 4 is a C-type clamp, which is used to clamp and fix the components that need to be replaced and positioned in the cockpit at the installation position, such as Figure 5 As shown; the protective sling 5 is made of synthetic fiber round sling, which is made of high-strength polyester filament, and has the characteristics of soft texture, light weight, large lifting force, large safety factor, non-conductivity, strong wear resistance, etc. It will not cause scratches on the surface of the aircraft. The two ends of the protective sling 5 are connected to the crossbeam of the gantry frame 1 to fix the nose.
[0022] During installation, when the gantry frame 1 is mounted, all beams and gantry columns of the gantry frame 1 are laser calibrated at any time with reference to the coordinate system after the aircraft is adjusted to be horizontal, to ensure their horizontality and verticality; connect the two ends of the protective sling 5 to the beams of the gantry frame 1, and adjust the length to fix the nose; after the position of the lifting mechanism 4 is determined, drill threaded holes at the corresponding positions of the X-axis, and then use bolts to connect, and the C-type clamps will clamp and fix the parts in the cockpit that need to be replaced and positioned at the installation position, such as Figure 6 shown.
