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 that the locomotive end joins tube connector.
Background technique
The working medium of locomotive brake gear is a 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 Security and the reliability of locomotive brake gear.
Train is housed at the locomotive two end part joins pipe, air feed uses for rear portion car brakeing machine; Have the locomotive that heavily joins function and also install total wind additional and join pipe and the average pipe that joins, give total reservoir and the master cylinder air feed of rear portion multi-locomotive respectively, the locomotive with two-tube air feed function, total wind joins pipe can also be to the equipment air feed of passenger vehicle vehicle.Locomotive have only the couplet pipe of an end using, and the couplet pipe of the other end need be fixed and the union-screw coupling mouth also need prevent dust when connecting vehicle or multi-locomotive.
The three kinds of metal connectors that join pipe in locomotive end (total wind, train, average); Be called for short by " connector "; Its form structure is complicated, and is as shown in Figure 2, and it is measure-alike with the connector pattern that on average joins pipe that wherein train joins the connector of managing; 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 that the locomotive end joins pipe.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 the dust guard front portion is circular, and thickness is 16mm, with the connector Spielpassung; Mid-rear portion is a rectangular; Afterbody has the oblique angle, matches with the welding inclined-plane of lifeguard.
Though dust guard is simple in structure, the problem that exposes is a lot:
1. dust guard and connector are fixing not firm, are prone to come off; And both Spielpassung are big, dustproof weak effect.
2. when dust guard and car body lifeguard weld, be difficult to guarantee soldering angle on the technology, after the overall package of being everlasting, need pull down welding again.
3. the dust guard integral material is Q235A, surface paint, but connector is a metalwork also, collision can make surperficial peeling paint when both connected, and made dust guard corrosion at short notice.
Summary of the invention
The locomotive end that the technical problem that the present invention solved provides a kind of fixation, difficult drop-off joins fixedly dust arrester of pipe.
The technological scheme that the present invention adopts is; The locomotive end joins fixedly dust arrester of pipe; Dust arrester integral body is fastened on the seal ring on the exhaust outlet of connector, and said dust arrester comprises dustproof seat, dustproof stifled and pressure spring, and dustproof seat fastens with connector shell; Be provided with spring between dustproof seat and dustproof the blocking up, dustproof stifled end face receives the pushing tow of spring to fit in seal ring.
Dust arrester also comprises pull bar, and dustproof seat is provided with through hole, and pull bar passes through hole and is connected in dustproof stifled.
Pull bar is provided with and lifts handle.
Pull bar and dustproof stifled being threaded.
Pull bar is provided with the shaft shoulder, and the shaft shoulder blocks the upper-end surface of dustproof seat.
Dustproof blocking up 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.
Dustproof seat is provided with engagement portion and following engagement portion, and the subordinate side of rising to the bait of connector is inserted in last engagement portion, and the following hook portion below of connector is withstood in following engagement portion.
Dustproof stifled, dustproof seat and pull bar are processed by stainless steel material.
Dustproof seat is provided with the fastening end, and the fastening end is connected in the connecting plate of cowcatcher through chek bolt.
The invention has the beneficial effects as follows, utilize the dustproof stifled exhaust outlet that blocks connector, the spring on the pull bar promotes dustproof stifledly simultaneously, and dustproof stifled end face is pressed on the O-ring seal of connector, and design had both been satisfied fixedly like this, played the effect of sealing again; Dust arrester of the present invention relies on chek bolt to be connected with the lifeguard transition plate, even the transition plate of welding has deviation, through regulating bolt, can make dust arrester reach desirable position; All parts of the present invention are stainless steel, can solve the problem of the existing easy corrosion of dust arrester peeling paint; Dustproof stifled simultaneously front portion be the wedge shape pattern, at connector with it fixedly the time, need the connector front end be put into wedge slot, exerts oneself a little one to push away, and can fix, and be easy to operate.

Be labeled as among the figure: the 1-pull bar, the 2-spring, 3-is dustproof stifled, the dustproof seat of 4-, 5 connectors, 6-joins pipe; The 7-dust guard, 9-seal ring, 31-seal face, 32-boss, the last engagement portion of 41-; Engagement portion under the 42-, 43-fastening end, the last hook portion of 51-, hook portion under the 52-, 53-exhaust outlet.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Locomotive of the present invention end couplet pipe fixedly dust arrester integral body is fastened on the seal ring 9 on connector 5 exhaust outlets 53; Critical piece comprises dustproof seat 4, dustproof stifled 3 and spring 2; Dustproof seat 4 fastens with connector 5 housings; Preventing dust is provided with spring 2 between seat 4 and dustproof stifled 3, and the dustproof seal face 31 that blocks up on 3 receives the pushing tow of spring 2 to fit in seal ring 9, stops dust to get into air pipe line.
For suitable with existing connector 5, dustproof seat 4 is provided with engagement portion 41 and following engagement portion 42, when being connected, and last hook portion 51 belows of last engagement portion 41 insertion connectors 5, following hook portion 52 belows of connector 5 are withstood in following engagement portion 42.
For the ease of installing, also be provided with the boss 32 of wedge shape on dustproof stifled 3, and dustproof seat 4 is provided with through hole, pull bar 1 passes through hole and is connected in dustproof stifled 3.When dust arrester is installed, whole dust arrester roughly is placed on the relevant position, is in free state for dust arrester, join tube connector 5 this moment and insert in dustproof stifled 3 wedge shapes, a little firmly one push away, can fix like Fig. 4, as shown in Figure 3.
Need to pluck when unloading from dust arrester when joining tube connector 5, one pulls moving pull bar 1, drives dustproof stifled 3 and withdraws from, and other hand can be taken and join tube connector 5.For mounting process is considered, pull bar 11 and dustproof stifled 3 adopts and is threaded, and for preventing to thread off, fastening glue is smeared at the 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 the transition plate of welding has deviation, through regulating bolt, can make dust arrester reach desirable position.
Dust arrester need adapt to the connector 5 of different size; Because it is measure-alike with average connector 5 patterns that join pipe that the train of locomotive joins pipe, so divide the dust arrester of two kinds of sizes on the locomotive, a kind ofly be total wind dust arrester; A kind of train dust arrester that cries, two kinds of dust arresters are formed by 4 parts.
Dustproof stifled 3, dustproof seat 4 and pull bar 1 are processed by stainless steel material, do not need spray paint.
