Description
Technical field
The present invention relates to railcar manufacturing technology field, more specifically to a kind of coupler carrier component and railcar.
Background technology
At present, can hitch height carry out even hanging with conclusive influence on railcar with other vehicles, and hitch height exists
Each stages such as the design of railcar, production, operation, maintenance are all the vehicle parameters paid close attention to and safeguarded.It is understood that
Hitch highly refers to height of the hitch away from track rail level.
Due to the secondary suspension height change caused by vehicle longtime running between wheel wear, bogie and car body and its
Particular/special requirement (such as install additional transition car coupler with other coupling of vehicles) factor during his car operation, it is easier to hitch occur highly low
In the situation of design requirement, cause even hang between vehicle.
The problem of can not even being hung for the highly too low caused vehicle of hitch, main solution has two kinds：The first
Scheme is from the hitch model for carrying height adjusting function；Second scheme is to install joist additional below hitch, and by adding
Weld pad plate compensates the reduction amount of hitch height caused by a variety of causes.Wherein, second scheme is mainly used on locomotive, the party
The major defect of case is can only to adjust height by being welded with pad, needs during implementation first to prepare different thickness according to hitch reduction amount
The pad of degree, cause the process for adjusting hitch height relative complex and the cycle is longer, influence the normal operation cycle of vehicle.
In addition, in second scheme, the regulation of hitch height is irreversible, i.e. hitch height can only be raised, it is impossible to drop
Low and recovery, flexibility are poor.
In addition, the first scheme is mainly used in city rail vehicle and EMUs vehicle, the height carried by hitch is adjusted
Function eliminates the problem of hitch is highly too low.But the selection of the model of hitch (is treated the hitch of coupling vehicle by each side factor
The Traction Parameters etc. of model, vehicle) influence, be easier to occur that the hitch with height adjusting function can not be selected, then the first
Scheme can only solve the highly too low problem of hitch of Some vehicles, and versatility is poor.
In summary, hitch height how is adjusted, to simplify the regulation of hitch height, it is highly desired to shorten regulation hitch
Time, it is current those skilled in the art's urgent problem to be solved.
The content of the invention
It is an object of the invention to provide a kind of coupler carrier component, for adjusting hitch height, to simplify hitch height
Regulation, shorten the regulation hitch highly desired time.It is a further object of the present invention to provide one kind to have above-mentioned coupler carrier group

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
As Figure 1-5, coupler carrier component provided in an embodiment of the present invention includes：Connector 2 and joist 3；Wherein, hold in the palm
Beam 3 is used to support hitch, and joist 3 is removably installed in connector 2, and joist 3 in the installation position on connector 2 along connector
2 short transverse is adjustable.
It is understood that joist 3 is adjustable in short transverse of the installation position on connector 2 along connector 2, then show to hold in the palm
When beam 3 is installed on different installation positions, the height of joist 3 is different, that is, realizes the height adjustable of joist 3.Above-mentioned vehicle joist
When component is applied, connector 2 and the car body of railcar is set to be fixedly linked, now, the short transverse of connector 2 is the height of car body
Direction is spent, thinks vertical direction.
Above-mentioned coupler carrier component, by the way that joist 3 is removably mounted on connector 2, and joist 3 is in connector 2
On short transverse of the installation position along connector 2 it is adjustable, then the height adjustable of joist 3 is realized, because joist 3 is used to support car
Hook, then the height adjustable of hitch is realized, in particular it is required that during regulation hitch height, it is only necessary to release joist 3 and connector 2
Connect and adjust the installation position of joist 3.When hitch is highly less than vehicle technology requirement, can be lifted by adjusting installation position
Hitch height is risen, hitch is highly returned to the numerical value of vehicle technology requirement, ensures that the company of vehicle hangs；When vehicle has special even extension
Duty requirements can adjust hitch height temporarily to meet that it is high that new company hangs, it is necessary to during coupling of vehicles from different hitch height
Degree；Hitch height can also be recovered after special operation is completed；
In coupler carrier component provided in an embodiment of the present invention, need to select difference according to hitch reduction amount compared with prior art
The pad of thickness and welding gasket is compared, is effectively simplified the regulation of hitch height, shorten regulation hitch it is highly desired when
Between.
Meanwhile in coupler carrier component provided in an embodiment of the present invention, joist 3 is removably mounted on connector 2, and
Joist 3 is adjustable in short transverse of the installation position on connector 2 along connector 2, then the height adjustable height of joist 3 can also be turned down,
Accordingly, the height adjustable height of hitch can also be turned down, and improve flexibility.
Meanwhile coupler carrier component provided in an embodiment of the present invention, structure is relatively simple, regulation operation is more convenient, dismounting
It is more convenient, it is applied widely, the AAR type hitches of rolling stock are cannot be only used for, can be used for the interim of tight lock couplers
