The specific embodiment
Shown in Fig. 3～5, dumping car 100 of the present utility model comprise vehicle frame 10, be arranged on the compartment 20 on the vehicle frame 10 and be connected vehicle frame 10 and compartment 20 between middle top lifting device 50.Usually, vehicle frame 10 comprises main car frame 11 that is arranged on the vehicle chassis and the subframe 15 that is arranged on this main car frame, and main car frame 11 and subframe 15 have the longeron 12 and 16 that pair of parallel is provided with respectively.Compartment 20 is pivotally connected on the subframe 15 by its base plate 21, and wherein, the below of cabin floor 21 also is provided with a pair of longeron 22, and these three pairs of longerons 12,16 and 22 align in vertical surface, makes that these three pairs of longerons 12,16 and 22 stack mutually when the compartment is set level.
Middle top lifting device 50 comprises two hydraulic actuating cylinders 51 that are arranged on the chassis side rail 12,16 and cabin floor longeron 22 outsides, one end of each hydraulic actuating cylinder 51 and undersetting 61 pivotal joints that are arranged on the vehicle frame 10, and the other end and upper bracket 62 pivotal joints that are arranged on the cabin floor 21.When hydraulic actuating cylinder 51 was in retracted mode, as shown in Figure 3, compartment 20 lay on the vehicle frame 10; And when hydraulic actuating cylinder 51 was in elongation state, as shown in Figure 4, compartment 20 was become heeling condition by lifting.
Because top lifting device 50 uses two the direct lifting of hydraulic actuating cylinder compartments in of the present utility model, and need not to be provided with the stroke enlarger, thereby hydraulic actuating cylinder 51 can be arranged on the outside of longeron.So just increase transverse pitch D2 between the lifting point (that is, the distance between two upper brackets 62), thereby improved the stability of compartment lifting.Preferably, can be with the arranged outside in upper bracket 62 as far as possible close compartments 20, to maximize this transverse pitch D2.In one embodiment, D2 can reach 1210mm.
In addition, the outside of chassis side rail 12,16 and compartment chassis member 22 is not provided with crossbeam usually.Thereby, for the setting of hydraulic actuating cylinder 51 provides sufficient space.When the compartment keeps flat, as shown in Figure 3, hydraulic actuating cylinder 51 in the horizontal direction can be overlapping with chassis side rail 12,16 and/or compartment chassis member 22, thereby make the center of gravity in compartment 20 to reduce, and improved the stability of dumping car 100 self.In the utility model, closed height B2 can be reduced to 370mm.Preferably, hydraulic actuating cylinder 51 is selected multistage hydraulic cylinder for use, the length when withdrawing to reduce it, thus reduce shared space.
Preferably, the structure of undersetting 61 is set, makes its longeron that is used for being lower than vehicle frame, with further reduction compartment center of gravity, satisfy the lifting requirement simultaneously with the connecting portion 611 of hydraulic actuating cylinder 51 pivotal joints.In order to improve the structural strength of undersetting 61, it can be fixed to simultaneously on a corresponding main car frame longeron 12 and the subframe longeron 16.At this moment, connecting portion 611 extends downward and is lower than main car frame longeron 12.Certainly, also can only undersetting 61 be fixed on main car frame longeron 12 or the subframe longeron 16.
Hydraulic actuating cylinder 51 when the compartment keeps flat is called as initial setting angle M with the angle of horizontal surface.Initial setting angle M is big more, and the hoisting force of hydraulic actuating cylinder 51 is also big more.Can choose different initial setting angles according to different vehicles, be preferably more than 45 °.In an embodiment of the present utility model, can under the system pressure of rated pressure 16MPa, obtain the hoisting force of 55 tons of goods of lifting.It should be noted that and select for use multistage hydraulic cylinder to help to increase this initial setting angle.
Preferably, also be provided with flow divider-combiner in the middle top lifting device 50, link to each other respectively, so that these two hydraulic actuating cylinders 51 can synchronous working with two hydraulic actuating cylinders 51.
In an embodiment of the present utility model, in the operator's compartment of dumping car 100, also be provided with the manual driven valve that is used for controlling this top lifting device 50.Like this, chaufeur can be in operator's compartment easily to the compartment carry out lifting, in stop, descend and/or slowly fall operation.
Though should be pointed out that by above-mentioned embodiment the utility model is described, yet the utility model also can have other numerous embodiments.Under the prerequisite that does not break away from the utility model spirit and scope; those of ordinary skill in the art obviously can make various corresponding changes and distortion to the utility model, but these changes and distortion all should belong in the scope that the utility model claims and equivalent thereof protect.
