Description
Affiliated technical field
The present invention relates to the anti-slide of a kind of rolling stock (or parking) device 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 easily lost, 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, must send someone to get on the bus before each the driving and unclamp rim brake, labour intensity is big, inconvenience, and it is complete to feel unwell, electrified section to hair line particularly, personnel's brake application platform is approaching probably or invade the high-voltage fence dangerous area accidentally, or because situations 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 by 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, the vehicle operating resistance is reduced greatly, 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 be subjected to the adjacent line train by 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 brake rail lifting mechanism, it is to develop by the local flow improvement innovation on existing tail of the peak stopping device basis.Shift fork cam, fan-shaped cam, connecting rod, brace, spring outer baffle are contained in this mechanism, its constructional feature is: shift fork cam and support are hinged, the shift fork head is by bearing pin and rod hinge connection, connecting rod two is hinged by bearing pin and fan-shaped cam, the brace bottom is seated on the fan-shaped cam working face, brace top is connected with braking rail by bolt, and the other end of brace is hinged by bearing pin and spring outer baffle.
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, realize the anti-purpose of braking of slipping, 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, and its process is with above-mentioned very good opposite during to mode of operation by off working state, thereby 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, keep the braking energy height and the technical index of former tail of the peak stopping device, can be implemented to hair line and the shared a kind of anti-slide product of line of shunting, and it is simple in structure, dependable performance, with low cost, easy to maintenance.
