Abstract
The invention discloses a kind of cast type primary couplers, including hitch mounting base, coupler body, snubber elastomeric part and anticreep chain；The hitch mounting base is fixed on vehicle frame end carriage, and the end of the coupler body passes through the vehicle frame end carriage and is connected to the hitch mounting base by the snubber elastomeric part；The two sides of the coupler body are respectively equipped with anticreep chain, and the vehicle frame end carriage is fixed in the end of the anticreep chain；The coupler body is integral type cast structure.The beneficial effects of the present invention are: 1, coupler body use integrated casting structure, eliminates the presence of welding stress, can effectively promote the service life of coupler body；2, the installation of snubber elastomeric part can substantially be reduced with impact force suffered by vehicle frame end carriage；3, after being provided with mousing-hook chain, vehicle hangs together unhook risk and substantially reduces, and effectively improves vehicle and hangs together safety coefficient.
Description
Technical field
The present invention relates to engineering truck primary couplers, and in particular to a kind of new-type primary coupler of cast type.
Background technique
Many freight railway vehicles are now for save the cost, and there is no dress standard hitches, and primary coupler is exactly for convenience
It hangs together and installs with this kind of vehicle.Traditional primary coupler is welded, and has the presence of welding stress, and due to not delaying
Flushing device can cause greater impact to vehicle frame end carriage.
Summary of the invention
In view of the deficiencies of the prior art, the present invention is intended to provide a kind of cast type primary coupler, can effectively overcome tradition small
The welding stress of hitch, and have the function of buffering and anticreep, effectively extend the service life of product, protect vehicle frame end carriage,
And enhance the safety used.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of cast type primary coupler, including hitch mounting base, coupler body, snubber elastomeric part and anticreep chain；The hitch peace
Dress seat is fixed on vehicle frame end carriage, and the end of the coupler body passes through the vehicle frame end carriage and is connected to institute by the snubber elastomeric part
State hitch mounting base；The two sides of the coupler body are respectively equipped with anticreep chain, and the vehicle frame is fixed in the end of the anticreep chain
End carriage；The coupler body is integral type cast structure.
It should be noted that the coupler body uses integrated casting structure, can exist to avoid existing welded structure and weld
The problem of scooping out power helps to improve the service life of coupler body.In addition, being buffered by increasing between hitch mounting base and coupler body
Elastic component then can reduce impact of the coupler body to vehicle frame end carriage when coupler body and other vehicles are hung together.And the setting of anticreep chain,
Can be effectively prevented vehicle hang together between the case where breaking off relations.
Further, the snubber elastomeric part uses buffer spring, and the inside of the hitch mounting base is installed equipped with spring
Set, the buffer spring is socketed in the spring installation set, and one end is fixedly connected on the end of the coupler body.When coupler body needs
When being hung together with the hook of other vehicles, biggish impact force may be generated to meeting frame end beam, pass through snubber elastomeric part (buffering
Spring) this impact force can be effectively buffered, to play protection vehicle frame end beam action.
Further, the anticreep chain is connected to vehicle frame end carriage by buffer unit.The setting of buffer unit equally may be used
To prevent anti-fall off chain item from generating excessive impact force to vehicle frame end carriage when the hook with other vehicles is interlocked.
Further, the buffer unit uses buffering compression spring.
The beneficial effects of the present invention are:
1, coupler body uses integrated casting structure, eliminates the presence of welding stress, can effectively promote the use of coupler body
Service life；
2, the installation of snubber elastomeric part can substantially be reduced with impact force suffered by vehicle frame end carriage；
3, after being provided with mousing-hook chain, vehicle hangs together unhook risk and substantially reduces, and effectively improves vehicle and hangs together safe system
Number.
Detailed description of the invention
Fig. 1 is the overlooking structure diagram of the embodiment of the present invention；
Fig. 2 is the side cross-sectional, view of the embodiment of the present invention.
Specific embodiment
Below with reference to attached drawing, the invention will be further described, it should be noted that following embodiment is with this technology
Premised on scheme, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to this
Embodiment.
As shown in Figs. 1-2, a kind of cast type primary coupler, including hitch mounting base 1, coupler body 3, snubber elastomeric part 2 and anticreep
Chain 4；The hitch mounting base 1 is fixed on vehicle frame end carriage 5, and the end of the coupler body 3 passes through the vehicle frame end carriage 5 and passes through institute
It states snubber elastomeric part 2 and is connected to the hitch mounting base 1；The two sides of the coupler body 3 are respectively equipped with anticreep chain 4, the anticreep
The vehicle frame end carriage 5 is fixed in the end of chain 4；The coupler body 3 is integral type cast structure.
In use, first with coupler body and the hook on the vehicle hung together is needed to be hung together, then anticreep chain is also joined
It locks on the hook on the vehicle for needing to hang together, that is, completes to hang together.
In above-mentioned cast type primary coupler, the coupler body uses integrated casting structure, can be to avoid existing welded type knot
There is welding stress in structure, help to improve the service life of coupler body.In addition, by between hitch mounting base and coupler body
Increase snubber elastomeric part, then can reduce impact of the coupler body to vehicle frame end carriage when coupler body and other vehicles are hung together.And anti-fall off chain
The setting of item, can be effectively prevented vehicle hang together between the case where breaking off relations.
Further, the snubber elastomeric part 2 uses buffer spring, and the inside of the hitch mounting base 1 is pacified equipped with spring
Encapsulation 6, the buffer spring are socketed in the spring installation set 6, and one end is fixedly connected on the end of the coupler body 3.When
When coupler body needs to hang together with the hook of other vehicles, biggish impact force may be generated to meeting frame end beam, pass through snubber elastomeric
Part (buffer spring) can effectively buffer this impact force, to play protection vehicle frame end beam action.
Further, the anticreep chain 4 is connected to vehicle frame end carriage 5 by buffer unit 7.The setting of buffer unit is same
It can prevent anticreep chain 4 from generating excessive impact force to vehicle frame end carriage when the hook with other vehicles is interlocked.
Further, the buffer unit 7 uses buffering compression spring.
For those skilled in the art, it can be provided various corresponding according to above technical solution and design
Change and modification, and all these change and modification, should be construed as being included within the scope of protection of the claims of the present invention.
