A kind of railway transportation open-top car
Technical field
The present invention relates to a kind of railway transport vehicle, is a kind of open-top car of railway delivery ore specifically, belongs to the railway transportation equipment field.
Background technology
The truck vehicle that carries cargo of railway mainly contains two kinds in boxed truck and open-top car, and other has some special vehiclees (as tank car, flat truck etc.).Traditional railway open top car car body is made up of headwall, side wall, underframe etc., lateral column is distributed in the outside of side wall, the floor is dull and stereotyped, the truck of this kind structure is heavy very big at axle, there is following shortcoming in wheel when big: the one, and vehicle body volume can not be accomplished maximum, can not make full use of gauge, improve the load-carrying of vehicle to greatest extent; The 2nd, the car load center of gravity is higher, has reduced the stationarity of vehicle operating.But along with the increasing of present logistics, the fierceness of competition aggravation, truck is in order to improve transport power, all to heavy duty, fast-developing, therefore necessary this improved.
Summary of the invention
The present invention mainly is the deficiency at above-mentioned traditional open-top car, and a kind of better truck of load-carrying of vehicle is provided.
The technical solution adopted in the present invention is: a kind of railway transportation open-top car, and its car body comprises headwall, side wall and underframe, and the open-top car lateral column is the die mould lateral column, and takes embedding structure, and the floor adopts the die mould projection to get out of the way the open-top car body construction of wheel.Concrete scheme is: the die mould lateral column is distributed in the inboard of side wall, and directly is connected with the sleeper beam upper cover plate with crossbeam, has both increased the volume of car body, has increased the intensity of side wall again; The section and the side wall of die mould lateral column have a certain degree, and are convenient to the tipper unloading; Die mould lateral column root adopts the circular arc brace panel, has both protected the weld seam of lateral column and sleeper beam and crossbeam upper cover plate, has increased the intensity of lateral column root again, has reduced the corrosion of lateral column root; Pressure-type structure is also adopted on the floor, in the wheel position projection, has reduced the height and the whole height of gravitational center of vehicle floor face, has improved vehicle smoothness; Because the side wall outside is more smooth, the resistance when also having reduced vehicle operating has improved vehicle smoothness.
In sum as can be seen, a kind of novel railway open-top car provided by the invention, more traditional macro-axis is heavy and big wheel truck floor is low, center of gravity is low, and load-carrying is big, from heavy and light, convenient manufacturing, maintenance, be suitable for and apply, can significantly improve the railway capacity, satisfy the requirement of railway truck heavy duty and speed-raising development.
Description of drawings
Fig. 1 is a schematic appearance of the present invention.
Fig. 2 is floor panel structure figure.
Fig. 3 is the lateral column constructional drawing.
Among the figure: 1, side wall; 2, underframe; 3, headwall; 4, floor; 5, projection; 6, wheel; 7, lateral column; 8, framed side wallboard; 9, circular arc brace panel; 10, crossbeam and sleeper beam upper cover plate.
The specific embodiment
Accompanying drawing has provided a specific embodiment of the present invention, and the invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, the present invention is a kind of heavy haul railway open-top car, and its car body comprises headwall 3, side wall 1 and underframe 2, and open-top car lateral column 7 is the die mould lateral column, and takes embedding structure, and floor 4 adopts the die mould projection to get out of the way the open-top car body construction of wheel.This open top car outward appearance is succinct, simple in structure, and whole side wall is very smooth, has reduced operating resistance, has improved vehicle smoothness.
As shown in Figure 2, pressure-type structures are adopted on open- top car floor 4, and 4 positions that are close with wheel 6 are provided with two projections 5 avoiding wheel 6 on the floor, and projection 5 is avoided wheel when the loaded vehicle operating mode, therefore can reduce the height of vehicle floor face, improve vehicle smoothness.
As shown in Figure 3, lateral column 7 is distributed in car body framed side wallboard 8 inboards, and lateral column 7 is in the same place with sleeper beam upper cover plate 10 direct connections with crossbeam, has both increased the volume of car body, has increased the intensity of side wall again; The section of lateral column 7 and framed side wallboard 8 have a certain degree, and are convenient to the tipper unloading; Lateral column 7 roots are provided with circular arc brace panel 9, have both protected the weld seam of lateral column 7 with sleeper beam and crossbeam upper cover plate 10, have increased the intensity of lateral column 7 roots again, have reduced the corrosion of lateral column 7 roots.
Hence one can see that, a kind of novel open-top car provided by the invention have load-carrying big, from heavy and light, Make things convenient for the tippler unloading, make and overhaul the advantages such as easy.
