Description
Technical field:
The present invention relates to a kind of railroad well car concave bottom frame loading end both ends beveled structures.
Background technique:
At present the beveled structure at railroad well car concave bottom frame loading end both ends mostly use greatly concave bottom frame bent angle upper cover plate with
It carries floor and forms 75 °~80 ° angle welding structures, due to design feature, the length of bent angle upper cover plate and carrying floor
And width dimensions are much larger than its thickness, the length and width of load-carrying 200t or more is close or larger than 2m, and thickness is
16mm~50mm, long-range is more, and because load-carrying is larger, and stress concentration is also easy to produce after dog-ear group is welded into cabinet, at dog-ear, is being designed
In, if increasing the thickness on bent angle upper cover plate and floor, it will cause the self weight of concave bottom frame and steeply rise, to improve light weight system
Number reduces speed of the vehicle by railroad bridge, influences vehicle technology parameter level, the cargo and railway that depressed center car is shipped
The cargo that universal vehicle is shipped is compared, and not only outer dimension is big, but also weight is also much bigger, therefore, at the dog-ear of loading end both ends
Stress is easily generated to concentrate.
Railroad well car is one of railway Heavy Duty Freight Car, and vehicle is more, and quantity accounts for railway Heavy Duty Freight Car sum
The features such as about 70%, it has structure simple, easy to use, safe and reliable to operation, concave bottom frame is railroad well car bearing goods
The big component of key, its weight usually accounts for 50% or more complete vehicle weight, and loading end both ends beveled structure is recessed Undercarriage structure
Key is concentrated to solve this stress, most in the design to have to using the thickness for increasing bent angle upper cover plate with carrying floor
Size is spent, thereupon, concave bottom frame weight steeply rises, and light weight coefficient passes through the performance parameters such as railroad bridge performance
It decreases.
The purpose of this product is to provide a kind of railroad well car concave bottom frame loading end both ends beveled structure, in design concave bottom
In frame, do not increase bent angle upper cover plate and carry the thickness of floor, uses this structure at section both ends, concave bottom frame and whole can be made
In the case that vehicle weight change is little, increase intensity, the rigidity of concave bottom frame loading end both ends beveled structure, solves stress concentration and ask
Topic improves vehicle technology parameter level to mitigate the self weight of concave bottom frame and vehicle.
Summary of the invention:
The object of the present invention is to provide a kind of railroad well car concave bottom frame loading end both ends beveled structures.
Above-mentioned purpose is realized by following technical scheme:
A kind of railroad well car concave bottom frame loading end both ends beveled structure, composition include: that dog-ear bottom plate, dog-ear are vertical
Plate, the dog-ear bottom plate form 78 ° of angles with the dog-ear vertical plate and are welded as a whole, the dog-ear bottom plate side tool
There are four socket, the socket is correspondingly connected with concave bottom frame web, below the dog-ear bottom plate with concave bottom frame dog-ear partition
Connection, the dog-ear bottom plate two sides are connect with concave bottom frame carrying floor respectively, the dog-ear vertical plate and concave bottom frame bent angle
Upper cover plate connection.
The railroad well car concave bottom frame loading end both ends beveled structure, the dog-ear bottom plate and dog-ear vertical plate shape
At integral solder is carried out after angle, after tempered processing, then carries out whole machinery and be process.
The railroad well car concave bottom frame loading end both ends beveled structure, the dog-ear base plate thickness are greater than concave bottom
Frame carries thickness 10mm~19mm of floor, and the dog-ear vertical plate thickness is greater than concave bottom frame bent angle upper cover plate thickness 20mm.
The utility model has the advantages that
1. present invention is generally directed to the concave bottom frame loading ends two of railroad well car concave bottom frame loading end both ends beveled structure
It is also easy to produce the shortcomings that stress is concentrated at the dog-ear of end, when designing concave bottom frame, enhancing concave bottom frame loading end is realized by beveled structure
Intensity, rigidity at the dog-ear of both ends solve the stress at the dog-ear of loading end both ends and concentrate, realizes and effectively mitigate the self weight of concave bottom frame,
The technical parameter for improving vehicle is horizontal.
Dog-ear bottom plate of the invention connects to form 78 ° of angles with the dog-ear vertical plate, angle two sides with small arc-shaped transition,
This structure can be avoided stress concentration.
After dog-ear bottom plate of the present invention and dog-ear vertical plate form angle, integral solder is carried out, after heat treatment, then carries out entirety
It is machined, dog-ear bottom plate is machined with the both ends docked of carrying floor, then by dog-ear vertical plate and bent angle
It is machined at upper cover plate docking, this structure can guarantee docking site flat appearance.
Dog-ear base plate thickness of the present invention is greater than the thickness of concave bottom frame carrying floor, and it is curved that dog-ear vertical plate thickness is greater than concave bottom frame
Angle upper cover plate thickness, this structure welding craftsmanship is strong, can guarantee welding quality, increases the stiffness and intensity of structure.
Height and length dimension of the invention is small, dog-ear bottom plate, dog-ear vertical plate thickness be respectively greater than bent angle upper cover plate and
The thickness of floor is carried, which has the characteristics that intensity, rigidity are big, and in the design, this product is loaded on railroad well car
Concave bottom frame loading end both ends can solve problem of stress concentration at the dog-ear of loading end both ends, reduce light weight.
