The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment utility model is described in further details.
Fig. 1, Fig. 2 and Fig. 3 have illustrated the residing three kinds of different conditions in the compartment of the utility model preferred embodiment one, compartment shown in Figure 1 is in just by the state of pushing tow, compartment shown in Figure 2 is in the state that rises in midair, and compartment shown in Figure 3 is in by the final condition of pushing tow.Lifting body mainly is made up of oil cylinder 3, upper beam 5 and underbeam 4, and the cylinder body 31 of oil cylinder 3 is hinged by the leading section of the girder 11 in connection hinge 311 and compartment 1, and the piston rod 32 of oil cylinder 3 is hinged by an end of connection hinge 43 and underbeam 4.The other end of underbeam 4 is hinged by being connected hinge 42 with the auxiliary girder on chassis 2.Put the beams in place 5 by connecting the middle part that hinge 45 and underbeam 4 are articulated in underbeam 4, the other end of upper beam 5 is hinged by connecting hinge 511 and girder 11.Compartment 1 is hinged by being connected hinge 12 with the chassis, and in this preferred embodiment, the upper beam 5 of lifting body and underbeam 4 have been formed a bending frame.
Fig. 4 and Fig. 5 have shown the different conditions of the utility model preferred embodiment two, in this preferred embodiment, oil cylinder 3 and compartment 1 do not have direct connection, lifting body mainly is made up of oil cylinder 3, upper beam 5 and underbeam 4, put the beams in place an end of 5 and girder 11 by being connected the middle part that hinge 511 is articulated in girder 11, put the beams in place 5 the other end and piston rod 32 by be connected cut with scissors 53 hinged.One end of underbeam 4 is by connecting the middle part that hinge 42 and auxiliary girder 2 are articulated in auxiliary girder 2, and its other end is hinged by connecting hinge 43 and cylinder body 31.Compartment 1 is hinged by being connected hinge 12 with the chassis.Upper beam 5 and underbeam 4 are scissors V shape combination.Oil cylinder 3 is connected (not shown) with hydraulic efficiency pressure system.
When piston rod 32 stretches out, the angle of upper beam 5 and underbeam 4 will increase, and upper beam 5 also makes pushing tow girder 11 compartment 1 around connecting hinge 12 upsets.When compartment 1 needs landing, piston rod 32 withdrawals, the angle of upper beam 5 and underbeam 4 reduces to fall after rise to the level of approximation position until compartment 1.
