The purpose of safety index.
Embodiment two
The present embodiment also adds wind path attachment device compared with embodiment one, which is used to connect wind
It manages and is installed in fixing device, and wind path attachment device is located at below circuit connecting mechanism (its cross section view is as shown in Figure 2).
The cross section view of railway freight-car circuit automatic picking off and hanging device as shown in fig. 13 that, including the fixed dress being connect with hitch
Put 17 with for connecting the wind path attachment device of air hose.Wherein, wind path attachment device is installed in fixing device 17, fixing device
17 are bolted on hitch, and are moved with hitch.
Fixing device 17 is equipped with the first through hole 3 communicated with air hose, and the structure of fixing device is as shown in Figure 3.
Wind path attachment device includes slidable valve rod 5 and the installation for being used to seal first through hole 3 in first through hole 3
In the valve rod spring 7 in first through hole 3, valve rod 5 is acted on by external force to 7 direction slide-open wind path of valve rod spring, and external force disappears
When by 7 active force of valve rod spring automatically reset close wind path.
Wherein, the internal structure of first through hole 3 is matched with the structure of valve rod 5, for improving the leakproofness of wind path.It is preferred that
, first through hole 3 is notch cuttype through hole, and cross section view is as shown in figure 4, ecto-entad includes level-one reducing hole 23, two successively
Grade reducing hole 24 and three-level reducing hole 25, the internal diameter in two level reducing hole 24 are less than the internal diameter in three-level reducing hole 25 and become more than level-one
The internal diameter in diameter hole 23.
Preferably, valve rod 5 is I-shaped, as shown in figure 5, close including the first sealing 20, second for being located at both ends respectively
Envelope portion 22 and the connecting portion 19 of intermediate undergauge, the first sealing 20 and the outer end face in level-one reducing hole 23 are fitted close, and second is close
Envelope portion 22 and the end face of 25 intersection of two level reducing hole 24 and three-level reducing hole are fitted close.Wherein, the first sealing 20 is cone
Body, minimum outer diameter are less than the internal diameter in level-one reducing hole 23, and maximum outside diameter is less than/is equal to the internal diameter in level-one reducing hole 23, excellent
Choosing, the maximum outside diameter of the first sealing 20 is close to the internal diameter in level-one reducing hole 23.When hitch plucks solution, in valve rod spring 7
Active force under, 20 part of the first sealing is protruded from outside level-one reducing hole 23, and close with the outer end face in level-one reducing hole 23
Coordinate to seal wind path；Second sealing 22 is located at the three-level reducing hole 25 of first through hole 3, and maximum outside diameter is more than two level reducing
The internal diameter in hole 24 and the internal diameter for being less than three-level reducing hole 25, when hitch plucks solution by 7 active force of valve rod spring and two level reducing hole
24 and the end face of 25 intersection of three-level reducing hole be fitted close to further improve the leakproofness of wind path.
Preferably, the outer end face in level-one reducing hole 23 is additionally provided with the first sealing ring 27, correspondingly, level-one reducing hole 23 connects
It is equipped at first sealing ring 27 and is sealed with 27 matched structure of the first sealing ring, preferred first sealing ring 27 for flange form
Circle, is on the one hand used for and the first sealing 20 coordinates for sealing itself wind path, when on the other hand can also even be hung in two section compartments,
The railway freight-car circuit automatic picking off and hanging device hung with the company for the treatment of combines closely and prevents from leaking out；Preferably, two level reducing hole 24 and three-level
The end face of the intersection in reducing hole 25 is additionally provided with the second sealing ring 28, for being further improved with the tight fit of the second sealing 22
Leakproofness.
Since the outer diameter of the first sealing 20 is less than the internal diameter in two level reducing hole 24, the outer diameter of the second sealing 22 is less than three
