A spring pull rod mechanism is adopted, the dustproof plug positioned on a pull rod is in extrusion fixing and seal with the seal ring positioned on an air outlet of a connector by means of the spring force, and the fixing dustproof device is extremely good in fixing and dustproof effects and suitable for dust prevention of the locomotive connecting pipe connector.
Description
Technical field
The present invention relates to the fixedly dust control technology field of locomotive end union connector.
Background technique
The working medium of locomotive brake gear is pressurized air.Compressed-air actuated quality directly affects the traffic safety of permutation car.Stop foreign matter to enter into air pipe line, most important to the safety and reliability of locomotive brake gear.
At locomotive two end part, train union is housed, air feed is used to rear portion car brakeing machine; Have the locomotive that heavily joins function and also install total wind union and average union additional, give respectively total reservoir and the master cylinder air feed of rear portion multi-locomotive, have the locomotive of dual pipe air supply function, total wind union can also be given the equipment air feed of Passenger Vehicle.Locomotive, when connecting vehicle or multi-locomotive, only have the union of one end using, and the union of the other end need to be fixed and union interface also needs to prevent dust.
The metal connector of the three kinds of unions in locomotive end (total wind, train, average), be called for short by " connector ", its form structure is complicated, as shown in Figure 2, wherein the connector of train union is measure-alike with the connector pattern of average union, connected fixedly dust arrester will take into full account fixing and dustproof, and the manufacturability of assembling.
Existing dust guard uses for many years as the fixedly dust arrester of locomotive end union.As shown in Figure 1, dust guard is to be formed by plate and card rod two-part assembly welding, and both are Q235A by material, and dust guard front portion is circular, and thickness is 16mm, with connector Spielpassung; Mid-rear portion is rectangular; Afterbody has oblique angle, matches with the welding inclined-plane of lifeguard.
Although dust guard is simple in structure, the problem exposing is a lot:
1. dust guard and connector are fixing not firm, easily come off; And both Spielpassung are large, and dust-proof effect is poor.
2. when dust guard and car body lifeguard weld, in technique, be difficult to guarantee soldering angle, after the overall package of being everlasting, need pull down welding again.
3. dust guard integral material is Q235A, surface paint, but connector is also metalwork, when both connect, collision can make surperficial peeling paint, makes dust guard corrosion at short notice.
Summary of the invention
The locomotive end union that technical problem solved by the invention is to provide a kind of fixation, difficult drop-off is dust arrester fixedly.
The technical solution used in the present invention is, locomotive end union is dust arrester fixedly, dust arrester integral body is fastened on the seal ring on the exhaust outlet of connector, described dust arrester comprises anti-dust seat, dustproof plug and Compress Spring, anti-dust seat and connector shell fasten, between anti-dust seat and dustproof plug, be provided with spring, dustproof plug end face is subject to the pushing tow of spring to fit in seal ring.
Dust arrester also comprises pull bar, is provided with through hole on anti-dust seat, and pull bar is connected in dustproof plug through through hole.
On pull bar, be provided with lift-pull handle.
Pull bar and dustproof plug are threaded.
Pull bar is provided with the shaft shoulder, and the shaft shoulder blocks the upper-end surface of anti-dust seat.
Dustproof plug is provided with seal face, and seal face and seal ring are suitable, and seal face is provided with boss, and boss is wedge shape.
Anti-dust seat is provided with He Xia engagement portion, engagement portion, and the subordinate side of rising to the bait of connector is inserted in upper engagement portion, and the lower hook portion below of connector is withstood in lower engagement portion.
Dustproof plug, anti-dust seat and pull bar are made by stainless steel material.
Anti-dust seat is provided with fastening end, and fastening end is connected in the connecting plate of cowcatcher by chek bolt.
The invention has the beneficial effects as follows, utilize dustproof plug to block the exhaust outlet of connector, the spring on pull bar promotes dustproof plug simultaneously, and dustproof plug end face is pressed on the O-ring seal of connector, and design had both met fixedly like this, played again the effect of sealing; Dust arrester of the present invention relies on chek bolt to be connected with lifeguard transition plate, even if the transition plate of welding has deviation, by adjusting bolt, can make dust arrester reach desirable position; The all parts of the present invention are stainless steel, can solve the problem of the easy corrosion of existing dust arrester peeling paint; Simultaneously dustproof plug front portion be wedge shape pattern, at connector with it fixedly time, connector front end need be put into wedge slot, exerts oneself a little one to push away, and can fix, easy to operate.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Locomotive of the present invention end union fixedly dust arrester integral body is fastened on the seal ring 9 on connector 5 exhaust outlets 53, critical piece comprises anti-dust seat 4, dustproof plug 3 and spring 2, anti-dust seat 4 fastens with connector 5 housings, between anti-dust seat 4 and dustproof plug 3, be provided with spring 2, seal face 31 on dustproof plug 3 is subject to the pushing tow of spring 2 to fit in seal ring 9, stops dust to enter air pipe line.
For suitable with existing connector 5, anti-dust seat 4 is provided with 41He Xia engagement portion, engagement portion 42, while being connected, and upper hook portion 51 belows that connector 5 is inserted in upper engagement portion 41, lower hook portion 52 belows of connector 5 are withstood in lower engagement portion 42.
For the ease of installing, on dustproof plug 3, be also provided with the boss 32 of wedge shape, and be provided with through hole on anti-dust seat 4, pull bar 1 is connected in dustproof plug 3 through through hole.When dust arrester is installed, whole dust arrester is roughly placed on to relevant position, as Fig. 4 be dust arrester in free state, now union connector 5 inserts in dustproof plug 3 wedge shapes, a little firmly one pushes away, and can fix, as shown in Figure 3.
When union connector 5 need be plucked while unloading from dust arrester, one pulls moving pull bar 1, drives dustproof plug 3 to exit, and another hand can be taken union connector 5.For mounting process is considered, pull bar 11 adopts and is threaded with dustproof plug 3, and for preventing threading off, fastening glue is smeared at screw thread place.
Dust arrester of the present invention extends outward a plate body, is fastening end 43, and fastening end 43 adopts the connecting plate of chek bolt and cowcatcher fastening, even if the transition plate of welding has deviation, by adjusting bolt, can make dust arrester reach desirable position.
Dust arrester need to adapt to the connector 5 of different size, because the train union of locomotive is measure-alike with connector 5 patterns of average union, so the dust arrester of minute two kinds of sizes on locomotive, be a kind ofly total wind dust arrester, be a train dust arrester, two kinds of dust arresters form by 4 parts.
Dustproof plug 3, anti-dust seat 4 and pull bar 1 are made by stainless steel material, do not need spray paint.
