Abstract
Passenger train hitch striker of the present invention, main body frame with welding fabrication, reinforcing plate is provided with main body frame, main body frame has the groove being engaged with end carriage coupler door top, the riser of the groove left and right sides is fixed on the both sides of end carriage coupler door by rivet, there is being used for of vertically opening up to install the rectangular opening of centering block hanger for the left and right sides of main body frame, and the distance that the lower plane of main body frame offers facade to draw gear shoulder before osculum, main body frame is more than the range of coupler draft gear.The present invention have adjusted the specific dimensional parameters of hitch striker for the hitches of CA 3; the distance of facade to draw gear shoulder before main body frame is set to be more than the range of coupler draft gear; well car body can be protected not to be destroyed, while simple to operation with the mounting structure of car body when buffer compresses.Hitch striker of the present invention is reasonable in design, and easy for installation, cost is relatively low, for being referred to or being used for reference using the car of the hitches of CA 3.
Description
Technical field
The present invention relates to a kind of passenger train hitch striker, belong to track vehicle body structure design field.
Background technology
The hitch striker of passenger train, which is located at hook, to be held, and is typically mainly prevented in body end portion by riveting
Train is in impact, and buffer reaches range, and hook shoulder hits car body end carriage and destroys car body.
Existing hitch striker is cast structure, although intensity is high but quality is big, installs inconvenient, it is fixed by rivet
On the top steel plate of end carriage coupler door.
Such as Fig. 1, existing No. 15 hitches striker schematic diagram is shown.In figure, 1 is end beam of underframe thereof, and 3 be No. 15 hitch punchings
Hit seat.The distance of the hook shoulder of No. 15 hitches to striker is 75mm, more than buffer stroke 73mm, when buffer compresses, car
Hook will not be contacted with striker, so as to play a part of protecting car body.
With the continuous developing of my company overseas market, run in early stage increases year by year, and some projects need to use CA-3 hitches.
And the hook shoulder of CA-3 hitches is 350mm away from coupling line size, with respect to No. 15 hitches are larger, if continuing to use original 15
Number hitch striker, the distance of hook shoulder to striker is 62mm, and less than buffer stroke 73mm, buffer is also uncompressed
During range, hitch collision impact seat causes car body to there is the risk deformed, and buffer can also not play one's part to the full,
Other coupler centre line is smaller to plane space on end carriage, and original impact seat installation structure and spatial relation can not be met
The requirement of CA-3 hitches.
The content of the invention
The technical problems to be solved by the invention are to overcome the disadvantages mentioned above of prior art there is provided a kind of passenger train
Hook striker.
In order to solve the above technical problems, the passenger train hitch striker that the present invention is provided, it is characterised in that：With weldering
It is connected into the main body frame of type, main body frame and is provided with reinforcing plate, the main body frame has matches with end carriage coupler door top
The groove of conjunction, the riser of the groove left and right sides is fixed on the both sides of end carriage coupler door, the left and right of the main body frame by rivet
Both sides have the rectangular opening for being used to install centering block hanger vertically opened up, and the lower plane of main body frame offers osculum, the master
The distance of facade to draw gear shoulder is more than the range of coupler draft gear before body framework.
In order to solve the above problems, the present invention also has feature further below：
1st, the riser of the groove left and right sides is fixed on end carriage coupler door by three rivets arranged in inverted triangle respectively
Both sides.
2nd, the thickness of the main body frame is 109mm, is highly 190mm, and facade is at a distance of draw gear shoulder before main body frame
81.5mm。
3rd, the upper surface of the main body frame is higher by end beam of underframe thereof upper surface 30-34mm.
4th, main body frame is welded using low-alloy high-strength steel plate.
Hitch striker of the present invention uses low-alloy high-strength steel plate welding fabrication, changes original striker monoblock cast
Form, intensity can meet design requirement while mitigating weight.Using sheet material weldment, manufacturing cost is reduced, is improved
Production efficiency.From unlike traditional scheme, the mounting interface of this striker and end carriage is arranged at the coupler door both sides of end carriage, should
It is rational in infrastructure, the higher situation of especially suitable coupler door, under the situation, the narrow space above end carriage, highly too low steel plate
Reliable fixed striker can not be used for.And the present invention program solves the problem.The present invention have adjusted car for CA-3 hitches
The specific dimensional parameters of hook striker, make the distance of facade to draw gear shoulder before main body frame be more than the maximum row of coupler draft gear
Journey, can protect car body not to be destroyed, while simple to operation with the mounting structure of car body well when buffer compresses.
Hitch striker of the present invention is reasonable in design, and easy for installation, cost is relatively low, for the car using CA-3 hitches
With reference to or use for reference.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is existing No. 15 hitches striker schematic diagram.
Fig. 2 hitch striker schematic diagrames of the embodiment of the present invention.
Fig. 3 is inventive embodiments hitch striker top view.
Fig. 4 is inventive embodiments hitch striker sectional view.
1- end beam of underframe thereof, 2-CA-3 hitch strikers, 3-15 hitch strikers, 4- rectangular openings, 5- osculums, 6- strengthens
Plate.
Embodiment
As shown in Figure 2, Figure 3, Figure 4, hitch of embodiment of the present invention striker is CA-3 hitch striker schematic diagrames, and it has
Reinforcing plate 6 is provided with the main body frame being welded using low-alloy high-strength steel plate, main body frame.The main body frame
Thickness is 109mm, is highly 190mm, and facade is at a distance of draw gear shoulder 81.5mm before main body frame, more than the range of buffer
（73mm）.The upper surface of main body frame is higher by end beam of underframe thereof upper surface 32mm.Main body frame has and end carriage coupler door top phase
The groove of cooperation, the riser of the groove left and right sides is fixed on the coupler door of end beam of underframe thereof 1 by three rivets arranged in inverted triangle
Both sides.The left and right sides of main body frame has the rectangular opening 5 for being used to install centering block hanger vertically opened up, and the lower of main body frame is put down
Face offers osculum 4, for draining.
In addition to the implementation, the present invention can also have other embodiment.All use equivalent substitution or equivalent transformation shape
Into technical scheme, all fall within the protection domain of application claims.
