Description
Technical field
The utility model relates to rolling stock technology field, in particular to a kind of swivel hook buffering apparatus.
Background technology
In rolling stock technology field, in order to ensure to carry out overturning unloading operation in not decoupling device state, railway truck comprises the swivel hook buffering apparatus of the turning end being installed on vehicle, in this coupler buffering device, as depicted in figs. 1 and 2, vitals comprises the couple yoke 2 ' of turning set 3 ' and supporting rotation.The swivel hook buffering apparatus of turning end is generally by hitch 1 ', couple yoke 2 ', turning set 3 ', draft key 4 ', energy disperser 5 ' and form from parts such as plates 6 '.Hitch 1 ' is connected with turning set 3 ' by draft key 4 ', and turning set 3 ' is arranged in couple yoke 2 ' front end inner chamber, from plate 6 ' and energy disperser 5 ' be installed on couple yoke 2 ' postmedian and before being limited in from plate 7 ' seat and after between plate 8 ' seat.Swivel hook buffering apparatus Main Function is the longitudinal impulse connecting rolling stock, transmit train longitudinal force (tractive force and compressive force) and relax between vehicle on the one hand; Be realize hitch 1 ' rotating relative to couple yoke 2 ' by the part fits such as turning set 3 ' and couple yoke 2 ' on the other hand, thus realize vehicle carries out vehicle overturning unloading operation in not decoupling device state.
When needing to carry out the overturning unloading operation of vehicle in not decoupling device state, coupler buffering device can realize hitch 1 ' relatively couple yoke 2 ' rotating function be because turning set 3 ' and the matching part of couple yoke 2 ' they are that circumference coordinates, turning set 3 ' can rotate and realize in couple yoke 2 ' inner chamber for this reason.Hitch 1 ' drives draft key 4 ', and draft key 4 ' drives turning set 3 ', thus realizes hitch 1 ' and draft key 4 ' and turning set 3 ' and rotate relative to couple yoke 2 ' together.
Usually at the operational process of vehicle, generally traction working condition and compression condition can be there is between vehicle, under traction working condition, tractive force pass order is: hitch 1 '-draft key 4 '-turning set 3 '-couple yoke 2 '-energy disperser 5 '-front is from plate 7 '-front from plate 7 ' seat-car body.Now, hitch 1 ' drives the lead motion in the same way of draft key 4 ' and turning set 3 ' and couple yoke 2 ', from plate 6 ' because by the front stop from plate 7 ' seat, it can not move to lead thereupon, therefore producing relative displacement from plate 6 ' and couple yoke 2 ', the contact site of the two being caused mutually to swipe because of contacting with couple yoke 2 ' from the bottom of plate 6 '.
Under compression condition, the pass order of compressive force is: hitch 1 '-front from plate 7 '-energy disperser 5 '-after from plate 8 ' seat.Now, hitch 1 ' moves to compression direction, promotes also to move to compression direction from plate 6 ' and energy disperser 5 ' pressure head, and thus energy disperser 5 ' bottom can not move from the restriction of plate 8 ' seat after being subject to.Therefore also producing relative displacement from plate 6 ' and couple yoke 2 ', making the contact site of the two to be caused mutually to swipe because of contacting with couple yoke 2 ' from the bottom of plate 6 '.
Therefore no matter be at traction working condition, or under compression condition, all can produce because of relative displacement to swipe with couple yoke 2 ' contact site from plate 6 ' bottom in coupler buffering device wears away.
At present, existing couple yoke 2 ' structure as shown in Figure 3 and Figure 4, in order to make the compact conformation of coupler buffering device, coordinates closely, being provided with spherical in this couple yoke 2 ' inner chamber and groove 21 ' is installed, when this installation groove 21 ' is for installing turning set 3 ', providing rotation space to turning set 3 '.When installing turning set 3 ', first turning set 3 ' being kept flat, erecting at installation groove 21 ' place after stretching into couple yoke 2 ' and installing, turning set 3 ' can be entered in couple yoke 2 ' head cavity.As shown in Figure 5, the spherical configuration of turning set 3 ' loads couple yoke 2 ' inner chamber arrange for coordinating with the installation groove 21 ' on couple yoke 2 '.The periphery of turning set 3 ' is arranged for coordinating to relatively rotate with the periphery of couple yoke 2 ' front end inner chamber after turning set 3 ' loads couple yoke 2 ' inner chamber.
As shown in Figure 6 and Figure 7, the process of installing turning set 3 ' in couple yoke 2 ' is: to be coordinated with the installation groove 21 ' on couple yoke 2 ' by the spherical configuration of turning set 3 ' and load couple yoke 2 ' inner chamber, the periphery of turning set 3 ' coordinates with the periphery of couple yoke 2 ' front end inner chamber after turning set 3 ' loads couple yoke 2 ' inner chamber, can relatively rotate.If it is to be understood that couple yoke 2 ' lower frame plate does not offer groove, turning set 3 ' can not load in couple yoke 2 '.
As shown in Figure 8, the setting of installing groove 21 ' because couple yoke 2 ' is upper, after making to be built up in couple yoke 2 ' from plate 6 ', from plate 6 ' bottom with the real contact area of couple yoke 2 ' lower frame plate only for dodging out the area installing groove 21 ', as shown in shade in Fig. 6 22 ' part.The groove position of couple yoke 2 ' lower frame plate then with from plate 6 ' bottom does not contact, just very little with the real contact area of couple yoke 2 ' lower frame plate from plate 6 ' bottom like this.When in coupler buffering device from plate 6 ' bottom with couple yoke 2 ' contact site produce scraping because of relative displacement time, will be very violent with the wearing and tearing of couple yoke 2 ' lower frame plate contact site from plate 6 ' bottom, cause couple yoke 2 ' lower frame plate thinning, reduce couple yoke 2 ' intensity.Simultaneously again because the abrasion loss from plate 6 ' is large, will cause moving down from plate 6 ' position, affect hitch 1 ' afterbody and coordinating from plate 6 ', and then affect the in-use performance of coupler buffering device.
