Description
Technical field
The utility model relates to the coupler and draft gear in a kind of transport vehicle draw gear, the especially draw gear.
Background technology
Because the difference of various countries' locomotive designing requirement,, cause the coupler and draft gear can not be general as the hitch structure in the coupler and draft gear, different apart from the height of rail level.Export to the Turkmenistan locomotive as the applicant, coupler centre line height to the top of rail 1050mm, the hitch model is the CA-3 type.And after this car finishes manufacturing at home, all must carry out test run, domestic hitch commonly used is interior electric car hook, coupler centre line height to the top of rail 880mm.The CA-3 hitch with in the fifth wheel profile of domestic electric car hook different, so the CA-3 hitch can not with the interior electric car extension that is hooked together.
The utility model content
The technical problems to be solved in the utility model provides a kind of exchange structure of coupler and draft gear, can satisfy the connection of the coupler and draft gear with different hitch requirements and hang.
The purpose of this utility model realizes by implementing following technical proposals:
A kind of coupler and draft gear exchanges structure, the hitch front end is connected with fixing striker by equalizer and suspension rod, coupler butt is connected with hook tail frame front end with draft key, it is characterized in that: also comprise the holder of tail frame, the holder of described tail frame comprises the hollow top board of the evagination that supporting plate and supporting plate middle part are connected; Supporting plate and vehicle frame draw beam are connected, top board apical grafting hook tail frame bottom.
Described hitch is the CA-3 hitch.
Described hitch is interior electric car hook; Be provided with the transition impact seat between described fixedly striker and the hitch front end; Described transition impact seat comprises that is fallen a L shaped Connection Block, and its upper end is a connecting panel, and its lower end and gooseneck bracket are connected, and between connecting panel and the gooseneck bracket gusset are set; Connecting panel and fixedly striker be connected, gooseneck bracket is by equalizer and the suspension rod hitch that is connected; The supporting plate of described tail frame holder is connected hook tail frame bottom and vehicle frame draw beam.
Between hook tail frame top and draw beam, be provided with anti-jump depression bar.
Adopt the coupler and draft gear of above structure to exchange structure, make full use of can be shared in the existing coupler and draft gear parts, by install the transition impact seat that is connected with it additional in coupler head, install the tail frame holder that is connected with it additional in hook tail frame bottom, satisfy the installation requirement of different hitch height, by increasing anti-jump depression bar, realized anti-jump preferably function.This exchange structure dismounting is quick, but the parts repeated use.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.But this should be interpreted as that the scope of above-mentioned theme of the present utility model only limits to following embodiment.
When locomotive test run or when transportation at home, the mounting structure of coupler draft gear is shown in Fig. 1,3,4,5,6,7.Interior electric car hook 3 afterbodys are connected with the hook tail frame 11 of shock absorber with draft key 7, pack into together in the vehicle frame draw beam, in hook tail frame bottom tail frame holder 9 is set, the holder of tail frame comprises the hollow top board 18 of the evagination that supporting plate 17 and supporting plate middle part are connected, the supporting plate of tail frame holder has 8 tapped bore, bolt with 8 M24 connects together supporting plate and draw beam, and top board does not contact with hook tail frame down at this moment.Shock absorber can forward and backwardly be moved in draw beam but can not drop out.Hitch front end and fixedly install transition impact seat 1 between the striker 2 additional, transition impact seat comprise that is fallen a L shaped Connection Block, and its upper end is a connecting panel 14, and its lower end and gooseneck bracket 16 are connected, and gusset 15 is set between connecting panel and the gooseneck bracket; The coupler head level is hung on the gooseneck bracket of transition impact seat with equalizer 4, suspension rod 6, again connecting panel and the fixing bolted of striker by 6 M24; Can make coupler centre line meet the requirement for height of 880mm apart from the height of rail level by adjusting pad.After installing coupling lever 5, anti-jump depression bar 10 additional, coupler and draft gear just can drop into normal test run or transport.
When locomotive is finished test run or transportation, when giving the user, the CA-3 hitch should change the outfit, its process is as follows: remove coupling lever, anti-jump depression bar, draft key, equalizer, suspension rod etc., interior electric car hook is extracted out from the end, pull down the tie bolt of holder of tail frame and draw beam again, with tail frame holder 9 turn-overs, after with external force the tail frame holder in the draw beam up being held up a height, top board apical grafting hook tail frame 11 bottoms of tail frame holder connect together again with the supporting plate and the draw beam of the bolt of pulling down with the holder of tail frame.The height that this moment, shock absorber rose promptly is the height of tail frame jacking plate, also is the difference of CA-3 hitch and interior electric car hook setting height(from bottom).Insert CA-3 hitch 12 from the end, coupler butt connects with hook tail frame 11 front ends with draft key 7.Load onto and separate shackles 13 and adjusting pad, the hitch height is transferred to dimensional characteristic, hitch exchanges and finishes, and its structure as shown in Figure 2.
Adopt the coupler and draft gear of above structure to exchange structure, make full use of can be shared in the existing coupler and draft gear parts, by install the transition impact seat that is connected with it additional in coupler head, install the tail frame holder that is connected with it additional in hook tail frame bottom, satisfy the installation requirement of different hitch height, by increasing anti-jump depression bar, realized anti-jump preferably function.This exchange structure dismounting is quick, but the parts repeated use.Owing to realized the hitch exchange, locomotive can not have fire and is recycled to the delivery station at home, the shipping of locomotive need not being disintegrated, thus reduced cost of transportation significantly.
