Description
Affiliated technical field
The present invention relates to the anti-slide of a kind of rolling stock (or parking) device and use brake rail lifting mechanism.
Technical background
At present; Extractd the car team to be separated of locomotive to resting on receiving track, perhaps finished the Che Zufang slide that does not hang up the one's own job machine at departure track, still none is unified and the behave of standard; Anti-accordingly slide measure can only be taked according to self-condition in each station; Sum up and get up to have following five kinds: skate is anti-to slip, and sabot is prevented slipping, braking by hand brake, little reservoir pressurize braking and the anti-slide of combination.
Iron (wood) footwear are anti-to slip, and needs to be equipped with full-time anti-slide personnel, and labour intensity is big, and inconvenience is prone to lose, in case lose or skate misplace or leakage are removed, certainly will cause train to slide down, squeeze trouble even overturns, and consequence is hardly imaginable.
Rim brake is anti-to slip, and must send someone to get on the bus before each the driving and unclamp rim brake, and labour intensity is big; Inconvenience, it is complete to feel unwell, particularly electrified section to hair line; Personnel's brake application platform is approaching probably or invade the high-voltage fence dangerous area accidentally, or because situation such as thunderstorm weather cause the electric shock operating personnel easily; Jeopardize personal safety, thereby have serious potential safety hazard.
Little reservoir pressurize braking is prevented slipping; And make an inspection tour brake cylinder piston overhang through the watch keeper and judge whether braking is effective; Once note abnormalities, the watch house of pulling up a horse is back got brake fastener and is remedied, if reasons such as the abominable or operating personnel's fatigue of natural environment cause and can not in time pinpoint the problems; So just might cause the car team runaway, exist potential safety hazard.In addition, hand brake fastener labour intensity is big, inconvenience.
Be not enough to guarantee under the security situation that the part station adopts that combination is anti-slips using separately above method prevent slipping, brake promptly that footwear (or rim brake)+little reservoir pressurize is braked, but root problem is still unresolved, potential safety hazard still exists.
Rolling stock changes antifriction-bearing box with bearing into by the plain bearing in past, and the vehicle operating resistance is reduced greatly, and standing vehicle just can start under less external force effect; The startability that this has improved locomotive has on the one hand reduced the energy consumption of locomotive, simultaneously; Also have higher requirement for the anti-slide of standing vehicle; Special have certain slope when circuit, add wind-force, geological process or receive the adjacent line train through the time vibration influence, cause standing vehicle generation runaway easily.
Summary of the invention
The objective of the invention is to prevent slide (or parking) device for railway vehicle ground provides a kind of brake rail lifting mechanism, satisfies railway to the static needs of preventing that slide and vehicle pass through fast of hair line vehicle.
The present invention solves its technical matters, and the technical scheme that is adopted is: the anti-slide of a kind of rolling stock (or parking) device is used brake rail lifting mechanism, and it is on existing tail of the peak stopping device basis, to develop through the local flow improvement innovation.Shift fork cam, fan-shaped cam, connecting rod, brace, spring outer baffle are contained in this mechanism; Its constructional feature is: the shift fork cam is made up of cam and shift fork; Shift fork is along the cam radial arrangement, and the front end of shift fork is provided with elongated hole, and hinged through the pin-and-hole at bearing pin and connecting rod middle part.Connecting rod two ends and fan-shaped cam are hinged, and the fan-shaped cam is hinged through another pin-and-hole and support.The fan-shaped cam working face is made up of two sections curves, diametal curves such as a Duan Wei, and another section is the reducing curve.The driving surface of fan-shaped cam is close to the brace bottom, when sliding on the diametal curves such as brace, and the braking rail translation; When brace was slided on the reducing curve, braking rail rose or falls.The front end of brace is provided with supporting plate, and supporting plate is provided with two holes, is used for connecting braking rail.The rear end of brace is provided with two convex shoulders, and convex shoulder is provided with concentric circle holes, and is hinged through this concentric circle holes and spring outer baffle.Brace top is provided with projection, and projection is provided with tapped bore, is used for connecting the braking rail trimming bolt.
This mechanism at first does the curve translation by shift fork cam driven connecting rod during from off working state to mode of operation, and drives the fan-shaped cam rotation by connecting rod; The jack-up brace of fan-shaped cam elder generation; Then, the shift fork cam is rotated further brace is pushed into retarder location, has realized the purpose of spreading after the braking rail elder generation jack-up.After braking rail is strutted by jack-up; Distance between two braking rail is greater than the vehicle distance between backs of wheel flanges, and to standing vehicle brake activation power, the purpose of slide braking is prevented in realization; Concerning slipping the driving; At this moment, wheel is to the extruding braking rail, and braking rail is granted the friction force consumption slide car kinetic energy of wheel face and realized braking.
This mechanism is during from mode of operation to off working state, its process and above-mentioned very good opposite during to mode of operation by off working state, thus realized the purpose that braking rail bounces back and afterwards descends earlier.After braking rail fell after rise and puts in place, less than 25 millimeters, the ultimate range between two braking rail satisfied the requirement that walking of one's own job machine and vehicle pass through fast less than 1353 millimeters to the braking rail vertex apart from stock rail end face distance at this moment.
Compared with prior art, the invention has the beneficial effects as follows: can satisfy to the static anti-needs that slip of hair line vehicle, avoid the various potential safety hazards that exist in the hair line vehicle anti-skid; Reduce labor intensity, improve operating efficiency, simultaneously; The braking energy height and the technical index that keep former tail of the peak stopping device can be implemented to hair line and shunt the shared a kind of anti-slide product of line, and simple in structure; Dependable performance, with low cost, easy to maintenance.
