Self-unloading loading body subframe
Technical field
The utility model relates to the component technology field of self-unloading loading body, refers to a kind of self-unloading loading body subframe especially.
Background technology
Existing self-unloading loading body subframe is welded by steel plate, and it comprises three crossbeams and two longerons, and three crossbeams are welded between two longerons, and the rear end of two longerons is respectively arranged with and two compartment upset support plate pivotally attached connecting bores.During use; The lower end of oil cylinder is installed between two oil cylinder connecting panels; The piston rod of oil cylinder upper end is fixed in below the cabin floor, and two longeron rear ends are hinged with two compartments upset support plates respectively, and the other end of two compartment upset support plates is fixed in below the base plate in compartment.Subframe just has been fixed in below the cabin floor like this, owing to the big heaviness of plate quality, has increased the overall weight in compartment, makes the compartment total consumption big.
The utility model content
The purpose of the utility model is to provide a kind of self-unloading loading body subframe, and it can guarantee to carry the overall weight that reduces the compartment under the situation of top Bottom Pressure, reduces the total consumption in compartment.
To achieve these goals; The technical solution of the utility model is: a kind of self-unloading loading body subframe; Comprise three crossbeams and two longerons; Three said crossbeams are welded between two said longerons, and the rear end of two said longerons is respectively arranged with and two compartment upset support plate pivotally attached connecting bores, and wherein three said crossbeams and two said longerons are processed by the aluminium-alloy pipe section bar.
The utility model self-unloading loading body subframe; The tube chamber that wherein is positioned at two said longeron rear ends is separately installed with a carbon steel embedding pipe; Be provided with a connection pipe with the cooresponding said carbon steel embedding tube cavity in said connecting bore position; Said connection pipe is all vertical with the axis of two said longerons, and the inner chamber of said connection pipe communicates with said connecting bore.
The utility model self-unloading loading body subframe, wherein the upper and lower surface of two said longerons is connected with first and second rubber tie plate respectively.
After adopting such scheme; Horizontal stroke, longeron that the utility model self-unloading loading body subframe is processed by the high strength aluminum alloy section bar are welded; Because high bearing capacity and characteristics in light weight that aluminium alloy extrusions has; Make this subframe under the prerequisite that can guarantee load capacity, reduced the overall weight of railway carriage, also just reduced the total consumption in compartment.
Description of drawings
Fig. 1 is the structural representation of the utility model self-unloading loading body subframe.
Below in conjunction with accompanying drawing, the utility model is done further explanation through embodiment;
The specific embodiment
As shown in Figure 1; The utility model self-unloading loading body subframe comprises crossbeam 1 and two longerons 2 that high strength aluminum alloy rectangle tubing is processed that three high strength aluminum alloy rectangle tubing are processed; Three crossbeams 1 are welded between two longerons 2; The rear end of two longerons 2 is processed with respectively and two compartment upset support plate pivotally attached connecting bores 21, and the tube chamber that is positioned at two longeron 2 rear ends is separately installed with a carbon steel embedding pipe 4, is processed with a connection pipe 5 with the cooresponding carbon steel embedding in connecting bore 21 positions pipe 4 inner chambers; Connection pipe 5 is all vertical with the axis of two longerons 2, and the inner chamber of connection pipe 5 communicates with connecting bore 21.The setting of this carbon steel embedding pipe 4 and connection pipe 5 is mainly used in the intensity that increases the self-unloading overturn point.The upper and lower surface of two longerons 2 is connected with first rubber tie plate 6 and second rubber tie plate 7 respectively.First rubber tie plate 6 and second rubber tie plate 7 are set are for vibration reduction and cushioning effect during vibration between subframe and the base plate.
Crossbeam 1, longeron 2 and oil cylinder connecting panel 3 that the utility model self-unloading loading body subframe is processed by the high strength aluminum alloy section bar are welded; Because high bearing capacity and characteristics in light weight that aluminium alloy extrusions has; Make this subframe under the prerequisite that can guarantee load capacity; Reduce the overall weight of railway carriage, promptly reduced the total consumption in compartment.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineering staff in this area make the technical scheme of the utility model all should fall in the protection domain that claims of the utility model confirm.
