Description
Technical field
The present invention relates to a kind of railway freight-car structure and device, more particularly to a kind of articulated car opened type draw beam to use and resist
Deformable supports device.
Background technology
With the progress of economic technology, railway freight-car gradually develops to customizations, and especially Container Transport is more and more in recent years
Generally, it is also increasing to Railway Container Transport car demand, Container Transport due to its it is intrinsic the characteristics of-concentrfated load work
Condition, thus it is higher to the Structural Design Requirement of container vehicle.Particularly special container flatcar, the carrying of end container
The relatives of Taiwan compatriots living on the Mainland are in cantilever design, and due to the height limitation of draw beam, the profile height of general end cross beam is smaller, simultaneously because end
The specific structure limitation of the uncovered structure of draw beam lower part, under big concentrfated load operating mode, the mutability of end crossbeam and draw beam
" ︵ " type that formed, causes intensity, the rigidity inadequate natural endowment of container flat car end crossbeam, reduces the service life of vehicle.
Chinese patent 200920278314.2 discloses a kind of railway container transportation platform wagon and is impacted with the anti-riveted type that cuts nail
Seat, the riveted type striker that cuts nail since this is anti-still uses the basic structure of prior art striker, and adds on this basis
Connecting plate, supporting block and supporting block reinforcing rib, in theory, the supporting block of which are stuck between draw beam lower cover, can be right
Draw beam and end carriage play booster action, Reducing distortion.But since supporting block depends on existing striker, connection mode is limited
In striker body, underaction；Secondly as the width of supporting block is certain, and draw the width between beam web and lower cover
Degree is due to manufacture factor, and each group of draw beam is all different, and the adaptability of supporting block is not strong on such a striker；Furthermore this prevents cutting
Nail riveted type striker uses integral cast process forming, and such as draw beam height change, the mould of supporting block part needs to adjust
It is whole, versatility deficiency, and it is likely to increase manufacture cost；Finally, due to supporting block depends on existing striker and supporting block
Width it is certain, if for a long time with whole striker is changed without after supporting block abrasion, supporting block may be ineffective.
Railway container flat car is due to the problem of limitation of carrying pattern and vehicle structure, end crossbeam and draw beam deform
The always common fault of container flat car development.Therefore, it is necessary to design a kind of new, simple in structure, cleverly, operation side
Just, can be widely used for railway container flat car opened type draw beam resistance to deformation support device, to strengthen end crossbeam and
