Description
Technical field
The present invention relates to a kind of connecting device of railway vehicle, especially a kind of motor train unit and existing rolling stock of being applicable to connects the transition hitch of hanging.
Background technology
At present; Adopt tight lock coupler on the motor train unit comprehensively; And the general common automatic car coupler (for example meeting the common automatic car coupler that TB/T2950-2006 rolling stock hitch connects the regulation of profile) that uses on the existing rolling stock; Above-mentioned two kinds of hitches are extensively utilization on the line all, but because structure is different fully, each other can not direct connection.For two kinds of dissimilar hitches are linked to each other, the existing rolling stock of realization is connected with motor train unit or speed-raising passenger vehicle, needs a kind of transition apparatus, is connected two kinds of dissimilar hitches.The constructional feature of transition hitch is that an end is connected with common automatic car coupler, and the other end is connected with tight lock coupler.Because textural difference is bigger, so manufacture difficulty is quite big.And the general structure of existing transition hitch is the first half of common automatic car coupler, complex structure, and weight is big, need the original tight lock coupler of motor train unit be pulled down during use, changes the transition hitch, and operation is inconvenience very.
Summary of the invention
The object of the present invention is to provide a kind of compact conformation, be convenient to operate and transition hitch that intensity is high.
In order to achieve the above object; Technical scheme of the present invention is: a kind of transition hitch; Comprise connecting device and hook tongue assembly; Said connecting device comprises common automatic car coupler connecting portion and tight lock coupler connecting portion, and said common automatic car coupler connecting portion and tight lock coupler connecting portion link together through inblock cast; Said common automatic car coupler connecting portion comprises S shape arc body and is connected baffle plate that the tight lock coupler connecting portion comprises convex cone and cavity; Be connected with plurality of strengthening ribs between the side of the back side of said common automatic car coupler connecting portion and tight lock coupler connecting portion; Said hook tongue assembly comprises hook tongue and pull bar, and pull bar is captiveed joint with the hook tongue, and hook tongue assembly is installed in the coupler knuckle chamber of tight lock coupler connecting portion, the corresponding cambered surface bearing fit of the arc surface of hook tongue and coupler knuckle chamber; Said hook tongue both sides have the arc gap, and place, coupler knuckle chamber both sides on the tight lock coupler connecting portion all has the annular arrangement locking plate, the annular arrangement locking plate stretch on the hook tongue in the corresponding lonely shape gap and with the arcwall bearing fit of arc gap; Have limiting stopper in the inner chamber of tight lock coupler connecting portion, can offset with limiting stopper during the pull bar swing.
Said connecting device is an inblock cast thin-walled cavity structure.
Said common automatic car coupler connecting portion is the thin-walled cavity structure, and in the cavity of its S shape arc body, is provided with the reinforcement dividing plate.
Said reinforced rib is a triangle.
Said reinforced rib is the triangle that belly has mesopore.
The both sides of the tight lock coupler connecting portion of said connecting device are provided with handle, convenient carrying.
Said annular arrangement locking plate is welded on the semi circular surface at the place, coupler knuckle chamber both sides on the tight lock coupler connecting portion.
Said pull bar is captiveed joint with the hook tongue through taper pin.
S shape arc body one end of said common automatic car coupler connecting portion is welded with the U-shaped anti-drop device.
The cross sectional shape of said reinforcement dividing plate is identical with the cross sectional shape of the cavity of S shape arc body, and the sectional area of perhaps said reinforcement dividing plate is less than the sectional area of the cavity of S shape arc body.
Said reinforced rib is connected between the side of the back side and tight lock coupler connecting portion of S shape arc body of common automatic car coupler connecting portion.
After adopting said structure,, and between the side of the back side of common automatic car coupler connecting portion and tight lock coupler connecting portion, be connected with plurality of strengthening ribs because common automatic car coupler connecting portion and tight lock coupler connecting portion link together through inblock cast; Therefore have that compact conformation, intensity are high, good reliability characteristics; Be installed in the coupler knuckle chamber of tight lock coupler connecting portion owing to hook tongue assembly again; The corresponding cambered surface bearing fit of the arc surface of hook tongue and coupler knuckle chamber; Therefore can make easily that through operation hook tongue assembly common rolling stock is connected with motor train unit; Need not to unload original tightlock coupler, operation is very easy.Particularly, when motor train unit et out of order or need loopback, just can realize motor train unit by existing locomotive traction, and can satisfy the requirement of fair speed loopback.
In addition, because said connecting device is an inblock cast thin-walled cavity structure, so alleviated weight greatly; Be convenient to carrying; Owing in the cavity of the S of common automatic car coupler connecting portion shape arc body, be provided with the reinforcement dividing plate, strengthened the pressurized and the tensile strength of said connecting device again, guaranteed that fully intensity of the present invention is high, the advantage of good reliability.
