Abstract
A kind of back-shaped ring beam middle chassis of railway flatcar.Existing flatcar underframe is generally made up of great underframe and little underframe, and load-carrying is little, and transport capacity is low, it is impossible to meet the demand of railway freight.The back-shaped ring beam structure of underframe in a kind of flatcar, its composition includes: girder forms, girder composition (1) is formed A(2 by little sleeper beam), center bearing composition (5), upper cover plate composition (6), lower cover composition (7), web composition (8) and little sleeper beam composition B(4) it is welded in V-shape, girder both ends connect little sleeper beam composition A and little sleeper beam composition B respectively, girder central part connects and is made up of center bearing, center bearing composition consists of the upper edge being connected to center bearing middle part upper cover plate (6 1) and upper cover plate, center bearing composition consists of the lower edge being connected to center bearing middle part lower cover (7 1) and lower cover, connection is also welded in the bottom of center bearing center bearing lower cover (5 1).This utility model is applied to back-shaped ring beam middle chassis of railway flatcar.
Description
Technical field:
This utility model relates to the back-shaped ring beam structure of underframe in a kind of flatcar.
Background technology:
For many years, articulated car occupies a tiny space in the Railway Freight Transportation of China, but existing articulated car
Underframe be generally made up of great underframe and little underframe, load-carrying is little, and transport capacity is low, it is impossible to meet the demand of railway freight.
Summary of the invention:
The purpose of this utility model is to provide the back-shaped ring beam structure of underframe in a kind of flatcar.
Above-mentioned purpose is realized by following technical scheme:
The back-shaped ring beam structure of underframe in a kind of flatcar, its composition includes: girder forms, and described girder is by little sleeper beam group
A, center bearing composition, upper cover plate composition, lower cover composition, web composition and little sleeper beam composition B is become to be in the shape of the letter V and be welded, institute
The girder both ends stated connect little sleeper beam composition A and little sleeper beam composition B respectively, and described girder central part connects center bearing group
Becoming, described center bearing composition consists of the upper edge being connected to center bearing, described center bearing middle part upper cover plate and upper cover plate
Forming and consist of the lower edge being connected to center bearing middle part lower cover and lower cover, connection is also welded in the bottom of described center bearing to be had
Center bearing lower cover, described girder composition forms back-shaped ring beam by every side upper cover plate, web and lower cover plate-welded.
The back-shaped ring beam structure of underframe in described flatcar, the little sleeper beam composition A at described girder two ends and little sleeper beam group
Become to be connected under B body center plate composition, respectively connected side bearing composition in the both sides of described body center plate composition.
The back-shaped ring beam structure of underframe in described flatcar, described girder composition also includes upper cover plate outside plate, upper cover plate
Middle plate, upper cover plate mend plate, middle part upper cover plate, lower cover composition, middle part lower cover, web composition, dividing plate, supporting plate.
Beneficial effect:
Back-shaped ring beam the most of the present utility model, in the flatcar between car body great underframe and little underframe on underframe, flatcar
The body center plate of middle underframe is connected with the center bearing of little underframe, and in flatcar, the center bearing of underframe is connected with the body center plate of great underframe, rises
Connect and carrying effect, use back-shaped ring beam, optimize body construction, alleviate middle underframe quality, and then improve vehicle load ability.
Back-shaped ring beam of the present utility model, uses cartridge to be connected with great underframe and little underframe, thus ensure that car load
Stability.
Back-shaped ring beam of the present utility model, is that this car is widely used in order to meet being actually needed of Enterprise Transportation
The technology such as Q345A low-alloy structural steel, curb girder carrying structure.
Back-shaped ring beam of the present utility model, has deadweight compared with the spy such as light, load-carrying big, simple to operate, and working service is convenient
Point.
Back-shaped ring beam of the present utility model, solves enterprise's vehicle and uses cost height, operation maintenance complexity, operation efficiency
Low grade is perplexed.
