Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1 and Figure 2, the present invention includes holistic fixed floor 1, some moving floors 2 be arranged on fixed floor 1, some horizontal position locking devices 3 for positioning and locking moving floor 2 and vertical position locking device 4.
As shown in Figure 3, Figure 4, the cross sectional shape of fixed floor 1 is convex, and center projections 11 dual-side of fixed floor 1 is respectively arranged with an intermediate incline 12.Fixed floor 1 shoulder of center projections 11 both sides is respectively arranged with evenly distributed some slotted holes 13.
As shown in Fig. 3, Fig. 5, moving floor 2 is hinged on the both sides of the edge of fixed floor 1 upper surface side by side, the inner side of each moving floor 2 arrange one match with the intermediate incline 12 of center projections 11 both sides coordinate inclined-plane 21, when moving floor 2 is horizontal, cooperation inclined-plane 21 inside moving floor 2 fits with the intermediate incline 12 of center projections 11, and the upper surface of moving floor 2 is concordant with the upper surface of center projections 11.The both ends of the surface of each moving floor 2 are respectively arranged with a tongue and groove 22, after such moving floor 2 drops down onto level attitude, adjacent two moving floors 2 being positioned at same row can realize overlap joint by tongue and groove 22, to make between two adjacent moving floors 2 the more tight of laminating.The end face of each moving floor 2 is also provided with two handles 23 for lifting moving floor 2.
As shown in Fig. 1, Fig. 6, each horizontal position locking device 3 comprises the lock 31 be welded on fixed floor 1, and the middle part of lock 31 is provided with an outwardly directed lock pin 32, and the end face of lock 31 is provided with the switch valve 33 be connected by spring device with lock pin 32.Corresponding with the installation site of horizontal position locking device 3, moving floor 2 is provided with and horizontal position locking device 3 engages indentation 24, and in breach 24, is provided with the lockpin hole 25 matched with the lock pin 32 of horizontal position locking device 3.When moving floor 2 is positioned at level attitude, controls lock pin 32 by switch valve 33 and insert in the lockpin hole 25 of moving floor 2, thus moving floor 2 is stably locked at horizontal position.
As shown in Fig. 2, Fig. 7, each vertical position locking device 4 comprises the mounting 41 be welded on carrier special vehicle sidewall 5, the top of mounting 41 connects a pressing plate 42 rotationally, be provided with the spring device 43 rotated for locking pressure plate 42 in the middle part of mounting 41, pressing plate 42 rotated and just moving floor 2 can be locked at vertical position to vertical position.
