Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical Novel protected range.
Fig. 1-Fig. 5 is please referred to, in a specific embodiment, the utility model provides a kind of lower support structure use In truck, it is particularly suitable for loading the truck of the bulk goods such as coal, ore, miberal powder, iron filings and steel slag.Bottom support Structure includes frame body and floor, and wherein frame body is main support section, is used to support floor, compartment and loading thereon Object, floor can prevent bulk goods from falling, which can be steel plate or iron plate.Specifically, the frame body includes along the railway The middle beam assembly of the length direction extension of open-top car is installed vertically on the transverse beam assembly of the middle beam assembly, and is installed on described It welds the joint of the end carriage component at middle beam assembly both ends, the middle beam assembly, the transverse beam assembly and the end carriage component Connect fixation;The floor is fixed in the frame body, and floor place opposite with the wheel of the truck is provided with evacuation knot Structure, avoiding structure are used to that wheel with bogie and thereon is avoided to collide.
Specifically, above-mentioned avoiding structure can be the die mould protrusion being arranged on floor, i.e., convex with floor integrated molding Rise, protrusion under floor it is rectangular at groove as avoiding structure.Theoretically, avoiding structure may be the aperture on floor Etc. structures.
Above-mentioned transverse beam assembly includes sleeper beam composition, first crossbeam composition and second cross beam composition, and the sleeper beam forms and institute Stating first crossbeam composition is two, and the two sleeper beam compositions are set to the outer of the two first crossbeam compositions correspondingly Side, the second cross beam group become multiple, and each second cross beam composition is distributed in the two first crossbeam compositions at intervals Between;Also, the frame body further includes stringer, and the stringer and the central sill member parallel are arranged, to improve holding for frame body Beijing South Maxpower Technology Co. Ltd's power.
In this way, the lower support structure welds the frame body to be formed using the multiple beam body of horizontal and vertical setting, and the bottom of at Design has avoiding structure on plate, so that it can reduce light weight, while can farthest avoid bogie wheel again With iron floor interference friction, to realize that light weight is small, load-carrying is big, the simple and safe technical effect of structure.
Specifically, beam assembly includes main beam and the draw beam for being welded in the main beam both ends among the above, wherein girder Body is used to play main supporting role, and draw beam is used to be connected by ipsilateral end carriage component with neighbouring support structure, institute It states transverse beam assembly and is welded in the main beam, the end carriage component is welded in draw beam ipsilateral therewith correspondingly.In this way, Middle beam assembly is welded by the draw beam at main beam and both ends, can guarantee stronger support strength, and avoids single length The excessive problem of amount of deflection caused by beam.
Above-mentioned main beam include to far from the floor direction be successively welded and fixed the first upper cover plate, the first web and First lower cover plate, draw beam include to far from the floor direction be successively welded and fixed the second upper cover plate, the second web and Second lower cover plate is welded with body center plate, rear draft lug and front draft lug on second lower cover plate.
According to the self weight demand of uniform strength design theory and reduction vehicle, the plate thickness of first web need to be less than the second abdomen The plate thickness of plate, specifically, the plate thickness of first web are less than at the maximum plate thickness of second web and are equal to described second At the minimum plate thickness of web, the thickness of second web from the maximum plate thickness to being gradually reduced at the minimum plate thickness, The plate thickness that the second web can be enabled to make its thickness be gradually decrease to the first web using the cut of the light grade mitigated.
Similar, according to the self weight demand of uniform strength design theory and reduction vehicle, the plate thickness of first lower cover plate is needed Less than the plate thickness of the second lower cover plate, specifically, the plate thickness of first lower cover plate less than at the maximum plate thickness of the second lower cover plate and At minimum plate thickness equal to second lower cover plate, the thickness of second lower cover plate is from the maximum plate thickness to the minimum It is gradually reduced at plate thickness, the second lower cover plate can be enabled so that its thickness is gradually decrease to the first lower cover using the cut of the light grade mitigated The plate thickness of plate.
In order to reduce the impact between adjacent structure, avoiding that impact failure occurs, the middle beam assembly further includes striker, The striker is welded in the end of the draw beam.Specifically, which includes being welded in rushing for second upper cover plate The lower joist and vertical plate for hitting plate, being welded in second lower cover plate, one end of the vertical plate be welded in the shock plate, its The other end is welded in the lower joist.
In addition to above-mentioned lower support structure, it is spacious that the utility model also provides a kind of railway including the lower support structure Vehicle, refer to the prior art for other Each parts of the truck, and this will not be repeated here.
