Abstract
The invention relates to a flat wagon center sill. The flat wagon center sill is characterized by comprising two supporting plates, a continuous upper cover plate and a dovetail-shaped lower cover plate, wherein the upper cover plate and the lower cover plate are welded on the upper and lower end faces of the two supporting plates respectively to form a box body, and two ends of the box body form two traction beams of the flat wagon center sill; in the box body, a plurality of inner clapboards are welded between the upper cover plate and the lower cover plate; a butterfly connector and an upper center plate are sequentially welded at the installation position of a center plate of each traction beam; and a rear draft lug and a front draft lug are welded in the cavities of the traction beams respectively. The two supporting plates are made into a fish belly type structure, the upper cover plate and the lower cover plate are welded on the upper and lower end faces of the two supporting plates to form the box body, and the plurality of inner clapboards are welded in the box body to form a plurality of small box bodies, so the integral stress intensity coefficient of the flat wagon center sill is greatly improved. The flat wagon center sill can be widely applied in the field of railway wagon transportation.
Description
Technical field
The present invention relates to a kind of middle girder construction, particularly about a kind of flatcar central sill that is used for the railway truck transport field.
Background technology
Domestic existing shared flatcar is about 21000, adopts a kind of traditional middle girder construction, when processing fish belly with H shaped steel or I-beam section; The transition of bending part employing great circle arc useless; And the draw beam lower flange does not overlap with follower seat, therefore causes the draw beam distribution of stress unreasonable, and bulk strength is low.For addressing this problem, adopt rectangle stiffening plate 1 and the big Eight characters stiffening plates 2 in front and back (as shown in Figure 1) in the cartridge installation place at present, this structure makes the central sill complex structure, and still, this manufacturing process difficulty is big, the many and intersection of weld seam, and fatigue life, grade was low.
Summary of the invention
To the problems referred to above, it is higher, simple in structure to the purpose of this invention is to provide a kind of strength coefficient, and can improve the flatcar central sill of grade fatigue life.
For realizing above-mentioned purpose; The present invention takes following technical scheme: a kind of flatcar central sill; It is characterized in that: it comprises the upper cover plate of two stay bearing plates, a continuous type and the lower cover of a dove-tail form; Said upper cover plate and lower cover are welded on respectively on the upper and lower end face of said two stay bearing plates, form a casing, and said tank ends forms two draw beams of said flatcar central sill; In the said casing, be welded with some internal partitions between said upper cover plate and the said lower cover; The cartridge installation place of each said draw beam, all assembly welding one butterfly connects and a body center plate successively, and welds a rear draft lug and a front draft lug respectively at said draw beam inner chamber.
Said two stay bearing plates adopt the fish-bellied type structure, and adopt the great circle arc transition structure at the interlude of fish belly variable section bent angle.
The interlude outside assembly welding one half-height type reinforcement gusset of said fish belly, inboard assembly welding has the semi open model internal partition.
The lower flange of said two stay bearing plates extends to the bottom of rear draft lug in the said draw beam.
Said two stay bearing plates all adopt H type shaped steel, I-beam section or steel plate assembly welding to form.
The present invention is owing to take above technical scheme; It has the following advantages: 1, the present invention is owing to process the fish-bellied type structure with two stay bearing plates, and at the upper and lower end face of two stay bearing plates welding upper cover plate and lower cover, forms a casing; And in this casing, be welded with several internal partitions; Form several small box, therefore, improved the whole stressed strength coefficient of flatcar central sill of the present invention greatly.2, the present invention is owing to be employed in the draw beam cartridge installation place, two ends of flatcar central sill; Assembly welding butterfly connecting panel and body center plate have been cancelled the front and back Eight characters covering plate structure at traditional central sill cartridge place, therefore successively; Simplified the structure of flatcar central sill greatly; Reduce weld seam simultaneously, and improved stress distribution, improved grade fatigue life.3, therefore the present invention, has avoided the problem of stress concentration of flatcar central sill bending part because lower cover adopts the dove-tail form structure.4, the present invention is owing to the interlude at two back plate fish belly variable section bent angles adopts the great circle arc transition structure; And the outside assembly welding one half-height type reinforcement gusset of this interlude; The inboard assembly welding in interlude two ends has the semi open model internal partition, therefore, has further strengthened the force intensity that receives of flatcar central sill.5, the flatcar central sill manufacturing of the present invention's employing is simple, is easy to batch manufacturing, and can effectively guarantees build guality.The present invention can be widely used in the railway truck transport field.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is carried out detailed description.
Like Fig. 2～shown in Figure 4; The present invention includes the upper cover plate 4 of two stay bearing plates 3, a continuous type and the lower cover 5 of a dove-tail form; Upper cover plate 4 is welded on respectively on the upper and lower end face of two stay bearing plates 3 with lower cover 5; Form a casing, this tank ends forms two draw beams 6 of flatcar central sill of the present invention.In this casing, be welded with some internal partitions 7 between upper cover plate 4 and the lower cover 5, casing is divided into several small box, and then has strengthened beam stress strength coefficient in the flatcar of the present invention.In the cartridge installation place of each draw beam 6, all assembly welding one a butterfly connecting panel 8 (as shown in Figure 5) and a body center plate 9 have successively avoided in the prior art many to intersect the shortcoming of weld seams, and can improve the distribution of stress.Also weld a rear draft lug 10 and a front draft lug 11 (as shown in Figure 1) respectively at draw beam 6 inner chambers, further improve the bulk strength of flatcar central sill of the present invention, simplify its structure, improve grade fatigue life.
In the foregoing description; Two stay bearing plates 3 adopt the fish-bellied type structure; Interlude 12 at fish belly variable section bent angle adopts the great circle arc transition structure; And the outside assembly welding one half-height type reinforcement gusset 13 (as shown in Figure 4) of this interlude 12, the inboard assembly welding in interlude 12 two ends has semi open model internal partition 14, to strengthen the force intensity that receives of interlude 12.
Among above-mentioned each embodiment, the lower flange of two stay bearing plates 3 extends to the bottom (as shown in Figure 3) of rear draft lug 10 in the draw beam 6, has improved the stress at draw beam 6 places greatly.
Among above-mentioned each embodiment, two stay bearing plates 3 can all adopt H type shaped steel, I-beam section or steel plate assembly welding to form.
Above-mentioned each embodiment only is used to explain the present invention; The structure of each parts, size, the position is set and shape all can change to some extent; On the basis of technical scheme of the present invention; All improvement and equivalents of individual component being carried out according to the principle of the invention all should not got rid of outside protection scope of the present invention.
