Detailed description of the invention
The present invention is described in detail below in conjunction with the accompanying drawings and preferred embodiment.
As shown in Figure 1 to Figure 3, a kind of air-drop is anti-turns over load bed device, comprise load bed 13, load bed base plate 14, four anti-translation frames 1 and two pulling-out mechanisms 2, the two ends on two the long limits being arranged on load bed 13 that four anti-translation frames 1 are the most vertical, two anti-translation frames 1 on each long limit of load bed 13 are respectively connected by a pulling-out mechanism 2, described pulling-out mechanism 2 includes cable wire 3, the two ends of cable wire 3 are fixed with pulls pin 4, piece cable wire 3 two ends pull pin 4 respectively on limit long with load bed 13 hole 12 of pulling pin of the anti-translation frame 1 at two ends coordinate, when cable wire 3 is strained, pull pin and 4 depart from anti-translation frame 1, anti-translation frame 1 rotates under self gravitation effect outside the long limit of load bed 13, level is transferred to by vertical state.
Pulling-out mechanism 2 simple in construction, saves space；Pull away by the way of tension cable wire 3 and pull pin 4, simple to operate；If pulling pin in cabin, 4 depart from anti-translation frame 1, and anti-translation frame 1 can automatically rotate and become level, the most easily discovers fault, processes in time.
nullAs shown in Figures 4 to 6，Described anti-translation frame 1 includes base plate 5、Auricle 6、Strut 7、Fagging 8 and locking mechanism，Base plate 5 is fixed on load bed 13 end face，Being fixed on base plate 5 of two auricle 6 symmetries，The bottom of strut 7 is arranged between two auricles 6 and hinged with two auricles 6，The top of strut 7 is fixed with fagging 8，The center of gravity of fagging 8 is positioned at the strut 7 side away from load bed，4 holes 12 of pulling pin coordinated of pulling pin with pulling-out mechanism 2 it are equipped with on the relevant position of strut 7 and two auricles 6，The line of hole 12 and hinge hole of pulling pin is vertical with base plate 5，Described locking mechanism is arranged on base plate 5 and is positioned at the both sides of strut 7，Locking mechanism includes fixed block 11，Dead bolt 9 and spring 10，Fixed block 11 is fixed on the auricle 6 side away from strut 7，Dead bolt 9 is cylinder，The middle part of dead bolt 9 is provided with the shaft shoulder，Fixed block 11、Auricle 6 is equipped with dead bolt hole on the relative position of strut 7，The two ends of dead bolt 9 dead bolt hole with auricle 6 and fixed block 11 respectively coordinates，Spring 10 it is cased with on dead bolt 9，One end of spring 10 contacts with fixed block 11，The other end of spring 10 and the end contact of dead bolt 9 shaft shoulder，The other end of dead bolt 9 shaft shoulder contacts with auricle 6.
In the present embodiment, one end end face that described dead bolt 9 coordinates with auricle 6 is inclined-plane, inclined-plane base plate dorsad.
As shown in Figure 4, pulling pin of pulling-out mechanism 24 coordinates with the hole 12 of pulling pin on anti-translation frame 1, owing to the line in pull pin hole 12 and hinge hole is perpendicular to base plate 5, so now strut 7 is in vertical state, owing to the center of gravity of fagging 8 is positioned at the strut 7 side away from load bed, so it is 4 compacted by eccentric force now to pull pin.
As shown in Figure 5 and Figure 6, pulling pin of pulling-out mechanism 24 leaves anti-translation frame 1, and the most anti-translation frame 1 is in level.From the beginning of 4 fully out anti-translation frames 1 of pulling pin, strut 7 rotates under the effect of self gravitation and fagging 8 gravity outside the hinged axial long limit of load bed 13, with the inclined-plane end contact of dead bolt 9 one end when strut 7 turns to certain angle, under gravity, strut 7 is pressed downward against dead bolt 9, downward pressure horizontal component on inclined-plane overcomes the horizontal thrust of spring 10 to be pushed away to the direction away from strut 7 by dead bolt 9, finally, strut 7 is pushed the dead bolt 9 of both sides open and is positioned at level, now, dead bolt 3 moves to strut 7 again under the thrust of spring 10, in coming back to original position and inserting the dead bolt hole of strut 7 correspondence position, strut is fixed.
