Description
Technical field
The utility model is related to a kind of lorry body structures, belong to railway freight-car technical field.
Background technology
Currently, domestic railway open wagon body is to constitute the rectangular of a surrounding and bottom lock by headwall, side wall and chassis
Body structure, the bulk goods such as coal, ore are packed by top, after vehicle transport to destination, are unloaded cargo by tippler
Go out, since end wall of car body, side wall and chassis form right-angle structure, causes unloading rear portion bulk goods remaining in the car, increase
Ineffective traffic is added.Additionally, due to structure design reason itself, for car body from great, load is few, increases transportation cost.
Invention content
The purpose of this utility model, which is to provide one kind, can reduce cargo remaining quantity, reduce car body dead weight, improve load-carrying
Lorry body structure.
The technical solution of the utility model is as follows：
The utility model includes chassis, both ends headwall, both sides side wall, it is characterized in that：Chassis is rectangle beam frame structure, bottom
Steel floor is covered on frame, headwall is made of the supporting beam of top end transverse member, end plate and end plate, and end plate is made of upper and lower two parts, top
It is divided into rectangular lower and is divided into isosceles trapezoid, side wall is made of top side rail, bottom side rail, side plate, and side plate is folded plate, the bending part of side plate
Position and bending angle match with the two sides of end plate edge；Both ends headwall, both sides side wall are connect with chassis surrounds a lorry vehicle
Body.
The chassis is made of central sill, end carriage, sleeper beam, crossbeam, longitudinal beam；
The supporting beam of the end plate includes left diagonal brace, right diagonal brace, cross band, left reinforcing beam, right reinforcing beam, and left diagonal brace and the right side are oblique
Support it is symmetrical be fixed on end plate at " V " shape, cross band is connected horizontally between left diagonal brace and right diagonal brace and is fixed with end plate,
Left reinforcing beam and right reinforcing beam be horizontally fixed on end plate lower part, left diagonal brace and right diagonal brace both sides；
It is symmetrical equipped with longitudinal pillow column, first-class of the side plate between two pillow columns at the side both ends of the side plate
Every be equipped with longitudinal lateral column；
The cross section of the pillow column is isosceles trapezoid；
The cross section of the lateral column is triangle.
The utility model has the advantages that：From heavy and light, load-carrying is big, reduces cargo remaining quantity；It is simple in structure, easy to operation and dimension
It repaiies.

Specific implementation mode
With reference to attached drawing, the utility model includes chassis 19, both ends headwall 20, both sides side wall 21, and chassis is rectangular shaped beam
Structure, Undercarriage structure include central sill 1, end carriage 2, sleeper beam 3, crossbeam 4, longitudinal beam 5.Installation step：First central sill 1 is positioned, then will
End carriage 2, crossbeam 4, in longitudinal beam 5 welding equipment to central sill 1, is covered with steel floor 6 at sleeper beam 3 on chassis.Headwall is by top end transverse member 8, end plate 7
It is constituted with the supporting beam of end plate, end plate is made of upper and lower two parts, and top is divided into rectangular lower and is divided into isosceles trapezoid, the branch of end plate
It includes left diagonal brace 9, right diagonal brace 10, cross band 11, left reinforcing beam 13, right reinforcing beam 12 to support beam, and left diagonal brace and right diagonal brace are symmetrical
Be fixed on end plate at " V " shape, cross band is connected horizontally between left diagonal brace and right diagonal brace and is fixed with end plate, left reinforcing beam and
Right reinforcing beam be horizontally fixed on end plate lower part, left diagonal brace and right diagonal brace both sides；Installation step：First end plate 7 is positioned, then will be upper
End carriage 8, left diagonal brace 9, right diagonal brace 10, cross band 11, right reinforcing beam 12, in left reinforcing beam 13 welding equipment to end plate 7.Side wall is by top side rail
15, bottom side rail 16, side plate 14 are constituted, and side plate is folded plate, and the bending part and bending angle of side plate are with the two sides of end plate along phase
It coincide；It is symmetrical equipped with longitudinal pillow column 17 at the side both ends of side plate, it is equally spaced on the side plate between two pillow columns
Equipped with longitudinal lateral column 18, the cross section of pillow column is isosceles trapezoid, and the cross section of lateral column is triangle；Installation step：First by side plate
14 positioning, then will be in top side rail 15, bottom side rail 16, pillow column 17, lateral column 18 welding equipment to side plate 14.Both ends headwall, both sides side wall with
Chassis connection surrounds a truck body.
End wall of car body, side wall lower part are designed as the structure with certain angle of inclination by the utility model, are combined with chassis
Surrounding is in funnel shaped afterwards, and when vehicle is in tippler dumping cargo, bottom cargo is taken advantage of a situation outflow, and reduction cargo remaining quantity carries
High conevying efficiency.
The utility model optimizes headwall, side wall, Undercarriage structure distribution and part section configuration, soft using finite element analysis
Part carries out Strength co-mputation to car body, under the premise of ensureing car body strength, to reach reduction wall thickness, to effectively reduce car body certainly
Weight.Concrete measure：
The utility model chassis uses unit-welded center sill structure, and according to uniform strength design theory, different bearer position is taken
Different wall thickness reduces dead weight；Optimize sleeper beam, crossbeam, sleeper beam, steel floor and middle beam connecting node, reduces wall thickness.
Headwall improves headwall intensity using the support construction of " V " type arrangement, and it is thick to reduce the parts such as wallboard, cross band, diagonal brace
Degree.
The lateral column section of side wall uses triangle, is variable cross-section form from top surface to bottom surface, while being filled in side wall and chassis
In matching, lateral column is corresponded to and is inserted into body transom, the bonding strength of side wall and chassis root is greatly improved, reduces part wall thickness.
