Abstract
The utility model relates to the technical field of internal combustion locomotives, in particular to a novel internal-combustion locomotive underframe which comprises a combined beam and a bearing type oil tank. The combined beam is composed of two main beams, and the bearing type oil tank is welded between the two main beams. The middle of each main beam is provided with combined structure of a box type fish belly sill and H-shaped steel, the H-shaped steel is arranged below box type fish belly sills, and upper cover plates of the H-shaped steel are lower cover plates of the box type fish belly sills. Rib plates in the bearing type oil tank are connected with the H-shaped steel, and holes are formed in the middle portions of the H-shaped steel and filled with thin steel plates. The end portion of the bearing type oil tank is provided with an anti-collision structure. The novel internal-combustion locomotive underframe can effectively meet the requirement for heights of middle fish bellies of box type fish belly sills, rigidity of a locomotive frame is improved, and strong bending resistance and fatigue resistance are achieved.
Description
Technical field
The utility model relates to the diesel locomotive technical field, the thorough frame of especially a kind of novel internal combustion locomotive.
Background technology
Generally all there is the weak problem of vehicle frame middle part vertical stiffness in the diesel locomotive of under-carriage carrying, causes the too low easy initiation equipment resonance of the natural frequency of vibration.
There is at present the under-carriage main beam structure of two kinds of forms, box fish belly sill+Non-carrying type Oiltank structure, box fish belly sill+bearing-type Oiltank structure, latter's rigidity outline is better than the former.But be subject to the impact of locomotive gauge and access for welding, the fish belly sill middle part of two kinds of structures highly all is difficult for too high, particularly in some girder spacing, design in wider vehicle, fish belly height design space, box fish belly sill middle part wretched insufficiency, cause vehicle frame rigidity to be difficult to meet and want.
The utility model content
In order to overcome the deficiency of existing technology, the utility model provides a kind of novel internal combustion locomotive under-carriage.
The utility model solves the technical scheme that its technical matters adopts: a kind of novel internal combustion locomotive under-carriage, adopt the structure of composite beam and bearing-type fuel tank, composite beam is comprised of two girders, the bearing-type fuel tank is welded between two girders, the middle part of described two girders is equipped with box fish belly sill and H shaped steel combination structure, H shaped steel is installed on the below of box fish belly sill, the lower cover that the upper cover plate of H shaped steel is the box fish belly sill.
According to another embodiment of the present utility model, further comprise that the gusset of described bearing-type fuel tank internal is connected with H shaped steel.
According to another embodiment of the present utility model, further comprise described H shaped steel middle part perforate and be provided with sheet steel and fill.
According to another embodiment of the present utility model, further comprise that described bearing-type fuel tank end is provided with collision protection structure.
The beneficial effects of the utility model are that the utility model can effectively meet the demand of box fish belly sill middle part fish belly height, improves vehicle frame rigidity, and has very strong anti-bending strength and fatigue resistance.

The specific embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of novel internal combustion locomotive under-carriage, adopt the structure of composite beam 1 and bearing-type fuel tank 2, composite beam 1 is comprised of two girders, bearing-type fuel tank 2 is welded between two girders, the middle part 11 of described two girders is equipped with box fish belly sill 3 and H shaped steel 4 unitized constructions, H shaped steel 4 is installed on the below of box fish belly sill 3, the lower cover that the upper cover plate 5 of H shaped steel 4 is box fish belly sill 3, box fish belly sill 3 is not separately being set cover plate, to reduce consumptive material and expendable weight.The utility model total has very strong anti-bending strength and strength at repeated alternation.
As shown in Figure 5, described H shaped steel 4 middle part perforates also are provided with the sheet steel filling, but expendable weight.
As shown in Figure 6, the gusset 21 of described bearing-type fuel tank 2 inside is connected with H shaped steel 4, can improve the stability of composite beam 1.
As shown in Figure 7, described bearing-type fuel tank 2 ends are provided with collision protection structure 6, can prevent that locomotive derailing rear fuel tank bump rail from breaking.
The utility model can effectively meet the demand of box fish belly sill middle part fish belly height, improves vehicle frame rigidity, and has very strong anti-bending strength and fatigue resistance.
In sum, it is only preferred embodiment of the present utility model, not be used for limiting the scope that the utility model is implemented, all equalizations of doing according to the described shape of the utility model claim scope, structure, feature change and modify, and all should be included in claim scope of the present utility model.
