Embodiment Construction
[0024] Such as figure 2 - Figure 4 As shown, a kind of jacking and quick-removal device used for the centering test of the aircraft front landing gear of the present invention includes a cylinder 21, which is installed on the working platform 25 upside down through the buffer spring 20, and the piston rod of the cylinder 21 The protruding end passes through the buffer spring 20, and the working platform 25 is fixedly connected with the working level 26. The top of the cylinder 21 is used to butt against the front landing gear. The buffer spring 20 at the bottom of the cylinder 21 is arranged on the reference platform of a stroke scale 23, and the horizontal mark 22 of the stroke scale 23 is freely lapped on the top of the cylinder 21, and moves on the stroke scale as the cylinder 21 moves up and down. Slide on the vertical pole of chi 23, like this, the moving distance of horizontal pole 22 is equal to the moving distance of cylinder 21 relative to vertical pole. The rodl...
