The specific embodiment
Below in conjunction with accompanying drawing, many present invention are described further:
Refer to Fig. 1, it is that airframe commercial transport loading system of the present invention comprises loading fixed equipment 1, loads water-tight equipment 2, loads lever system 3.
Wherein, what load fixed equipment is divided into two kinds, a kind of for slide rail loads fixed equipment, and a kind of is that ground sheet frame loads fixed equipment.
As shown in Figure 2, slide rail loads fixed equipment and comprises and load joint 4 and bolt 5, and bolt 5 holdings, in sliding-rail groove, and are spirally connected with loading joint 4, and loading joint is fixed on slide rail face.During loading, load is delivered on slide rail by loading joint 4, and it both can apply upwards load, also can apply down load, meets simultaneously and loads positioning requirements.
As shown in Figure 3, ground sheet frame loading fixed equipment comprises special joint 6 and holding bolt 7.Wherein, special joint 6 is class ears structures, and its two sides are placed on the architrave bar of floor, adopt 7 holdings of holding bolt on ground sheet frame web.During loading, load is delivered on ground sheet frame by special joint 6, and this equipment only can apply down load, meets and load positioning requirements during test.
