Task of the present utility model has following technical scheme to realize, developed a kind of self-discharging semitrailer, it comprises: the compartment assembly, the traction pin, supporting leg, the hydraulic pressure lifting device, wheel set, the rear portion is fixed with the turnover hinge seat at the bottom of this railway carriage or compartment, compartment, this is hinged on the wheelspan beam carline rear end of wheel set by hinge, the front end of this beam carline is fixed with the lifting pedestal of hydraulic pressure lifting device, on this pedestal jack cylinder is housed, end is hinged on central authorities at the bottom of the railway carriage or compartment by the elevate a turnable ladder hinge elevate a turnable ladder longeron middle part is lifted on the top of this oil cylinder, on the elevate a turnable ladder longeron in this elevate a turnable ladder hinge the place ahead, also be fixed with axis pin base, this axle bed is hinged with the envelope pull bar, the other end of this pull bar is hinged on again on the traction beam carline, this beam carline and wheelspan beam carline conllinear, but partial installation, also be provided with traction pin and supporting leg on the traction beam carline of this split, when this compartment assembly is axle when being lifted into the inclination flip state by hydraulic pressure lifting device top with the turnover hinge, be hinged on the envelope pull bar between traction beam carline and the elevate a turnable ladder longeron, by this compartment envelope the wheelspan beam carline push-and-pull of wheel set is moved, to adjust the axletree distance of traction headstock and wheel set, guarantee the binding of this car integral body and tractor truck.
This self-discharging semitrailer, described compartment assembly, it is to be fixedly connected into the bar case frame envelope that three fixed compartment walls, a upper hinge are opened the railway carriage or compartment wall down respectively with the post that stands like a wall, end stull by the limit longeron of two pairs of rectangular cross sections, inner chamber five faces of this envelope are equipped with thin skin sheet material, central authorities are provided with and pass through long elevate a turnable ladder longeron at the bottom of the railway carriage or compartment of this envelope, thereby constitute the compartment assembly with loading strength.
This self-discharging semitrailer, described wheel set, it is arranged on the rear portion, compartment, below the wheelspan beam carline, be fixed with suspension holdfast, wheel of wherein per two seat supports supporting, by the difference of carrying capacity, this wheel set can be provided with one, two, three the wheel number of axle, and corresponding suspension holdfast number can be provided with 2 to 4.
Self-discharging semitrailer of the present utility model, its advantage is: owing to improved the structure of vehicle frame bottom girder, become the vehicle frame of two sections beam carlines of split type conllinear by the vehicle frame of long longeron framework, thereby reduced the consumption of longeron, saved steel.Owing to be provided with the envelope pull bar between the elevate a turnable ladder longeron of central authorities at the bottom of the railway carriage or compartment that is hinged on the traction longeron, again because the limit longeron of rectangular cross section has sufficient intensity and rigidity for key compartment assembly structure, thereby chassis frame, can be designed to the vehicle frame of two sections beam carlines of split formula conllinear, this vehicle frame utilizes conjuncted, the effect of adjusting the axletree distance of envelope pull bar, can form telescopic longeron vehicle frame, improve the compartment flexible overturning of this dumping car, safety.These split type two sections beam carlines can adopt the different model steel respectively according to its supporting power, have improved stock utilization, accomplish each most its material of steel, and the beam carline of general wheel set can have employing 20
#Channel-section steel, and the traction beam carline can adopt 16
#Channel-section steel.
Embodiment of the present utility model further describes as follows in conjunction with the accompanying drawings: as shown in the figure,
Fig. 1 is: the flat whole car shape scheme drawing that crouches of self-discharging semitrailer.
Fig. 2 is: the lateral plan during the inclination flip compartment of self-discharging semitrailer.
Fig. 3 is: the oblique upward view during the inclination flip compartment of self-discharging semitrailer.
The self-discharging semitrailer of 12 tons of load-carryings of making, the long 7.2m of its compartment assembly 1, high 1m, wide 2.4m.Traction pin 2 and supporting leg 3 are located on traction beam carline 10 frameworks.The rear portion is fixed with turnover hinge seat 6 at the bottom of the railway carriage or compartment of compartment assembly 1, and this 6 is hinged on wheelspan beam carline 8 rear ends of wheel set 5 by hinge 7, and the front end of this beam carline 8 is fixed with the lifting pedestal 14 of hydraulic pressure lifting device, on this pedestal 14 jack cylinder 4 is housed.End is lifted by elevate a turnable ladder hinge 22 in the top of this oil cylinder 4, is hinged on elevate a turnable ladder longeron 20 middle parts of central authorities at the bottom of the railway carriage or compartment.Elevate a turnable ladder hinge 22 the place aheads on this longeron 20 also are fixed with axis pin base 11, and this axle bed 11 is hinged with envelope pull bar 9, and the other end of this pull bar 9 is hinged on again on the traction beam carline 10.This beam carline 10 and wheelspan beam carline 8 conllinear, but partial installation.
