Among the figure: the 1-track foundation; The 2-sleeper; The 3-track; The 4-check rail; 5-protects barricade; 6-energy-absorbing block; The 7-proliferation part; 8-energy-absorbing parts; The crashproof cuff of 9-; 10-station column.
The specific embodiment
Below in conjunction with accompanying drawing to principle of the present invention, structure and and concrete enforcement be described further:
This protector is made up of four lines of defense altogether, the first line of defence: check rail; Defence line, second road: protection barricade; Three lines of defence: energy-absorbing block; Four lines of defense: protection cuff.
The first line of defence: in the middle of the track 3 of house post 10 1 sides that pull in, traditional check rail 4 is set, arrive a station train (40km/h is following) for low speed, if after the unexpected derailing of train, its single wheel is blocked by check rail 4, the opposite side wheel is positioned on the sleeper 2, and car body slightly tilts to cylinder, and train is in guiding downslide departures house post 10 scopes of check rail 4, unlikely bumping, and can not cause damage to train substantially.
Defence line, second road: 3 arrange protection barricade 5 between station column 10 and track, and protection barricade 5 is high 40～60cm, and the inboard is the concrete structure of arc, and the inboard of this concrete structure and track foundation 1 are connected as a single entity.Pass through (40～80km/h) for medium speed's train, when check rail 4 can't stop the derailing train, protection barricade 5 can make derailing train one sidecar wheel be positioned on the sleeper 2, the opposite side wheel is positioned on the protection barricade 5, car body is to rolling tiltedly away from station column 10, train will be in guiding downslide departures house post 10 scopes of protection barricade 5, and this moment, train only can very limited damage occur at positions such as wheel and supports, at utmost alleviate the destruction that train may be subjected to.
The three lines of defence: being installed on the protection cuff 9, being positioned at the energy-absorbing block 6 of the same side with track 3, highly is 1.5～2.5m, and the center is 1.5～2m apart from track 3 elevation of waters, is made up of proliferation part 7 and energy-absorbing parts 8.Proliferation part 7 disperses the bump strength of station column 10 for the train that will derail, and is made by steel plate or steel flap, and the thickness of steel plate is generally about 20mm.The kinetic energy dissipation that impact after energy-absorbing parts 8 are used for disperseing reaches is combined by the thin-walled square steel pipe of filling out reticulated foams aluminium in many rows, and the wall thickness of thin-wall steel tube is generally about 2mm, internal diameter 10cm, length 20cm, foamed aluminium density 300～500kg/m
3, for (80～160km/h), protection barricade 5 can retrain the outside translation of derailing train, but train rolling may take place and bumps against with station column 10 by train at a high speed.At this moment; energy-absorbing block 6 can stop the outside tumbling motion of train; and its kinetic energy that dissipates; thereby can effectively protect station column 10; and because the distortion of energy-absorbing block 6 power consumption; gross distortion takes place in the train of can avoiding derailing in knockout process, thereby effectively protects the inner passenger's of train safety.
Four lines of defense: station column 10 arranged outside protection cuff 9, the protection cuff is welded into by 20～40mm steel plate, be set in station column 10 outsides, distance from top track 3 horizontal planes 2～3m, the protection cuff can effectively increase station column 10 impact resistant capability, for by speed greater than the main track of 160km/h by train, in case under the situation that takes place derailment accident and preceding three lines of defence all to lose efficacy, train will inevitably take place to collide firmly with station column 10.Protect cuff and can bring into play triple protective actions this moment: local impact's power of 1. disperseing bullet train; 2. improve flexural strength and the bending rigidity of column; 3. retrain the column concrete, improve concrete intensity and ductility.Thereby can effectively avoid the station column to meet with bump and lost efficacy, guarantee station structure and internal staff's safety.
