Abstract
The utility model provides a dump truck, wherein, a platform floor is arranged on an auxiliary frame, the auxiliary frame comprises two longitudinal beams, a plurality of cross beams are connected with the two longitudinal beams, two auxiliary longitudinal beams are respectively arranged on the outer sides of the longitudinal beams, the auxiliary longitudinal beams are fixed on the longitudinal beams through a bracket, the platform floor is matched with the upper surface of the auxiliary frame, and the cross section of the platform floor can be in the shape of a straight line, a circular arc, a trapezoid, an arch or an axially symmetrical multi-section straight line. The compartment provided by the utility model has the advantages of wide transverse brace span, large contact area and good stability. To construct the compartment chassis of the dump truck without the use of longitudinal and cross beams has the effects of lowering the center of gravity, reducing wind resistance coefficient, improving stability, greatly improving the safety in driving the dump truck, reducing the consumption of steel, reducing dead weight, increasing useful load, greatly reducing welding workload, reducing cost and improving visual effect.
Description
Technical field
The utility model relates to a kind of autotruck, particularly the self-unloading autotruck.
Background technology
At present the dumping car that uses has underframe under the cabin floor, is contacted with two longerons of subframe by the longeron of underframe, and area of contact is little, and two longerons of subframe, one meter of less than apart, and lateral stability is very poor, and subframe is fixed on the vehicle frame.The self-unloading autotruck generally delivers materials such as coal, ore, earth, and load carrying ability is big.Fully loaded material tailheaviness height, bottom, compartment only by subframe two longerons support, the lateral stability in compartment is poor, usually because the road injustice is jolted or turned and suddenly slightly just turns on one's side, causes the grave accident of personal injury during fully loaded material.In order to improve the stability in compartment, some dumping trucks have been cancelled the compartment underframe, directly be placed on the compartment on the subframe, though reduced center of gravity, but the compartment still supports by two longerons of subframe, do not increase area of contact, the cross-tie width is also very narrow, and the situation of compartment lateral stability difference does not improve.
The utility model content
The utility model aims to provide a kind of dumping truck, and center of gravity is low, and the area of contact of compartment and subframe is big, and subframe is wide to the cross-tie span in compartment, the compartment good stability.
The technical solution of the utility model is: a kind of dumping truck, cabin floor place on the subframe, and subframe comprises two longerons, and some crossbeams connect two longerons, and respectively there is a secondary longeron in the longeron outside, and secondary longeron is fixed on the longeron by support.
Described crossbeam and longeron upper surface flush.Secondary longeron is a little more than longeron.Support is 2 to 5.
Steel plate is arranged on the subframe, and cabin floor places on the steel plate.
Described cabin floor and subframe upper surface are suitable, and the base plate cross-sectional plane can be for flat line shape, circular arc is linear, trapezoidal, arc or with the multistage linear of axis symmetry.
The cabin floor upper surface vertically has 1-5 root reinforced rib.The cabin floor lower surface laterally has plurality of strengthening ribs.
Cabin floor comprises 2 to 3 layers of steel plate, and the vertical boss of 3-5 bar is arranged on the orlop steel plate.
The cross-tie span in the utility model compartment is wide, area of contact is big, and good stability has been cancelled the longitudinal and transverse beam of compartment underframe, not only reduced center of gravity, improve stability, the safety of vehicle ' is improved greatly, also reduced steel consumption, alleviated deadweight, improve load, significantly reduced the welding job amount simultaneously, cost-cutting.The reinforced rib on the upper and lower surface of cabin floor makes the compartment that enough rigidity and intensity be arranged.
Description of drawings
Fig. 1 is the utility model side schematic view.
Fig. 2 is the utility model schematic cross-sectional view.
Fig. 3 is another structure schematic cross-sectional view of the utility model.
Among the figure: 1-compartment, 2-cabin floor, 3-waling, the secondary longeron of 4-, 5-vehicle frame, 6-subframe, 7-crossbeam, 8-longeron, 9-support, the horizontal reinforced rib of 10-, 11-boss.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As Fig. 1, shown in 2, the utility model body of tipper carriage 1 has been cancelled original vertical, crossbeam, cabin floor 2 places on the subframe 6, subframe 6 comprises two longerons 8, some crossbeams 7 connect two longerons 8, crossbeam 7 upper surfaces can with longeron 8 upper surface flush, can increase the area of contact of subframe 6 and cabin floor 2 like this, in two longeron 8 outsides a secondary longeron 4 is arranged respectively also, secondary longeron 4 is fixed on the longeron 8 by support 5, and support 5 comprises two blocks of side plates and a backing plate, support 5 one ends are fixed on the secondary longeron 4, the other end is captiveed joint with longeron 8 through backing plate top, and the bottom on vehicle frame 5, can be 2-5 according to the length support 5 of subframe 6 by bolted connection.The height of secondary longeron 4 can flush with longeron 8, also can put a steel plate again on the subframe 6 a little more than the height of longeron 8, and cabin floor 2 places on the steel plate, further increases area of contact, improves stability.In the contact site, the shape of cabin floor 2 and subframe 6 upper surface shapes are suitable, and specifically, from transversal surface, cabin floor 2 is consistent with subframe 6 upper surface shapes.Cabin floor 2 transverse shapes can be for flat line shape, circular arc is linear, trapezoidal, arc or with multistage straight line of axis symmetry etc., cabin floor 2 can be one deck, also can be made up of 2 to 3 layers of steel plate.
Further,, some reinforced ribs vertically are set, can be the 1-5 root according to box width at the cabin floor upper surface for strengthening the strength and stiffness in compartment; Cabin floor is by under 2 to 3 layers of situation that steel plate is formed, and the orlop steel plate of cabin floor 2 has the vertical boss 11 of 3-5 bar 8 of two longerons, and as shown in Figure 3, boss 11 repressed forming can further improve the strength and stiffness in compartment; The cabin floor lower surface also is provided with some horizontal reinforced ribs 10, and length is the position of compartment frame to secondary longeron, and quantity is set according to car length, can be 2-8.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
