Description
Technical field
The present invention relates to railway traffic equipment, especially a kind of track line switch area is from oiling slide plate.
Background technique
Track switch is the line connection equipment that rolling stock was transferred to or crossed another station track from a station track, is the weight of railroad track
Component part is wanted, is the critical infrastructures for influencing driving stationarity and safety.Important part of the slide plate as track switch, it
Under tongue and basic rail assembly, within the scope of entire length of switch rail support tongue, withhold stock rail.When train passes through point
When rail, stock rail enter track switch, if tongue transition shift is insufficient, the traffic safety of train will be directly affected.Tongue and slide plate
Between frictional force as conversion power an important component, if slide plate skin-friction force is excessive, it will cause to convert
Resistance increases, and aggravates the abrasion of goat, and even will cause tongue pulls phenomena such as not closely connected when serious, influences traffic safety.
Try to reduce the conversion resistance force between trouble area's tongue and slide plate, improves the operational reliability of track switch, be always that domestic and international railway is ground
The target studied carefully.
For the conversion resistance force for reducing trouble area's tongue, increase the operating reliability of track switch, extends goat service life, China
There are mainly two types of currently used methods.One is trouble area's slide plates to apply oil lubrication, i.e., by it is artificial periodically in trouble area's tongue and
Coating lubricating oil between slide plate, to reduce sliding friction between the two, to achieve the purpose that reduce tongue conversion resistance force.So
And with the continuous raising increased with speed of railways train operation density, the curing cycle of track structure is shorter and shorter, workload
It is increasing, need to consume a large amount of manpower and material resources etc..At the same time, for the time of upper track operation also with running speed and
The raising of rate of traffic flow and constantly reduce, cause the conflicting of maintenance and operation.Another method is using novel
Slide plate structure mainly has roller slide plate and two kinds of self-lubricating turnout baseplate, but the two still comes with some shortcomings, mainly
Show themselves in that the slide plate needs near installation roller apparatus are widened, roller diameter is by slide plate height limitation, and structure is complicated, valence
Lattice are expensive, only use in some new routes at present；Self-lubricating turnout baseplate mostly uses oil containing powder metallurgical material, oil-containing
Ceramic material, graphite dispersion alloy, plasma sprayed ceramic etc. have certain effect, but effect is not obvious, and vulnerable to weather
Condition, material itself service life etc. factor influence, and applicability is limited.As it can be seen that above-mentioned novel sliding bed board still cannot
Replace traditional trouble area oiling slide plate structure completely.
Summary of the invention
That it is an object of the invention to provide a kind of maintenance work intensity is low, oiling is high-efficient, the track circuit of good reliability
Switch area is from oiling slide plate.
Track line switch area of the invention is from oiling slide plate, including slide plate, which is characterized in that sets inside slide plate
There are oiling chamber, shoe cream room, fuel tank and oil transportation duct, fuel tank is located at topmost, and the upper end is equipped with pouring orifice, and lower part is provided with fuel-displaced
Mouthful；Piston obstructs the inside that slide plate is arranged in, and the inner end of piston stalk is connect with pushing piston, upper end connect with connection piston, is outer
End is stretched out can contact except slide plate with tongue, push piston with piston is connected to and be respectively at the interior of oiling chamber and shoe cream room
Portion；The oil outlet of fuel tank connects with the upper end of shoe cream room, is connected between shoe cream room and oiling chamber by upper oil transportation duct, and oiling chamber is logical
Oil transportation duct is crossed down to communicate with the oil outlet on slide plate on tongue sliding working face；It is connected to lateral surface the going out fuel tank of piston
Hydraulic fluid port blocking, connection internal piston are equipped with piston duct, and shoe cream room is connected to through being connected to the piston duct of piston with fuel tank；Piston stalk
Spring is also equipped between slide plate；To guarantee that inner and outer air pressure maintains an equal level, ventilation hole is offered above shoe cream room.
Track line switch area of the invention is mounted on the track plate on sleeper from oiling slide plate, slide plate one end button
It is pressed on stock rail, while support tongue, its working principle is that, when trouble area's tongue is separated with stock rail, tongue will live just
Plug stalk is fully advanced inside slide plate, and slide plate is in running order.At this point, spring is fully compressed, fuel tank oil outlet and work
The alignment perforation of consent road, upper oil transportation duct are pushed piston closure, and fuel tank internal lubricating oil is flowed out by fuel tank oil outlet, through piston
Duct flow to storage in shoe cream room；Wait branch off area's tongue again converting motion and with stock rail closure it is closely connected when, tongue will be with work
Plug stalk is separated, and at the same time, spring starts to reset relaxation and piston stalk is pushed to move outward, and the outer shifting of piston stalk also can band
It is dynamic to push piston and be connected to shifting outside piston synchronous, so that slide plate is in reset state, at this point, being connected to piston just by fuel tank
Oil outlet blocks completely, and the closure to upper oil transportation duct can then be released by pushing piston, and ventilation hole ensure that inside and outside air pressure balance, storage
Lubricating oil in oil pocket will flow to the intracavitary storage of oiling through upper oil transportation duct；When slide plate is again at working condition, push away
Pressure piston will squeeze the intracavitary lubricating oil of oiling, and the lubricating oil for promoting oiling intracavitary flows to lower oil transportation duct, finally by slider bed
The oil outlet of plate working face flows out.Recycle repeatedly, can complete trouble area's tongue slide plate from oiling operations.
Track line switch area of the invention can effectively solve traditional slide plate oiling cost of labor from oiling slide plate
The low problem of height, oiling heavy workload, operating efficiency has the advantages that oiling is high-efficient, good reliability, substantially improves maintenance
Operating condition reduces maintenance work amount, saves maintenance labour cost, increases the operating reliability of track switch, extends goat and uses
Service life, reduce railway points system failure rate, to ensure train turn safely line operation be of great significance.
