The specific embodiment
The content of the following stated is the detailed description of in conjunction with the accompanying drawings the present invention being done, and should not be understood that it is limitation of the invention.
Please consulting Fig. 1 earlier, is side of the present invention whole structure scheme drawing, and as can be seen from the figure the present invention is made up of track and maglev vehicle two parts, wherein:
Train head 1 is cleanliness, between car door 2, driver door 7, boot compartment car door 3, vehicle window 4 and the covering 5, and is smooth smooth seal contact between each joint connection seam of train, to reduce the resistance and the compartment oxygen seepage of operation apoplexy.Whole train moves in sealed vacuum pipeline 6, and the degree of vacuum of this pipeline 6 is 10 -2About.Pipeline both sides You lookout window 33 , Gai look at window 33 and can be used as Emergency Exit and free air diffuser.Ground is greening lawn 9, and duct bottom is about 6 meters apart from ground surface lawn.
H-girder 10 is made by prestressed reinforced concrete, and its middle part is provided with breather port 11, to reduce the pressure of wind.The termination 12 of H-girder 10 is overlapped on the inverted T shape door beam 13.Be provided with temperature joint between H-girder 10 terminations 12 and the inverted T-shaped door beam 13, and connect with bolt.Inverted T shape door beam 13 and the column 14 under it are that the casting of cement concrete one forms portal frame 15.
Please in conjunction with Fig. 2 and Fig. 3, steel pipe 6 is fixed by bolts to H-girder 10 belows, and for strengthening the impregnability of pipeline 6, the inner tubal wall compartment of terrain of pipeline 6 is provided with metal compression ring 30, is such as but not limited to 1.2 meters and establishes a compression ring 30.This compression ring 30 is compounded with and hangs pillow 34, hangs the pillow 34 belows inversion spill hanger rail 8 that has two ferrimagnetism steel plates to make, and this hanger rail 8 is provided with bolster 16 with hanging between the pillow 34, by bolt 17 hanger rail 8 and bolster 16 is fixed on to hang to rest the head on 34 to be linked to be integral body.Groove 32 on this hanger rail 8 is tracks of air gap position-limited wheel described later and drive wheel.Steel pipe 6 is made up of several road joint assemblies, and each road joint assembly is such as but not limited to 12 meters long, connects with bolt each other, is provided with the sealing expansion joint on each point of connection.Be evacuated by vacuum pump 41 in the pipeline.About sealing expansion joint and vacuum pump is known in those skilled in the art, and the present invention seldom describes this, does not also recommend accompanying drawing.
Please, be the generalized section of maglev vehicle of the present invention in conjunction with consulting Fig. 4.Maglev vehicle of the present invention is that alloy or glass-felt plastic are made into integration, and is made up of top piggyback pod 19 and main cabin, bottom two parts, and the bottom also can be a cargo hold, also can be divided into main cabin 20 and cargo hold 21.Magnetic suspension piggyback pod 19 is overall vehicle actuating unit of the present invention, and its structure is a left-right symmetric.The termination, bulkhead 27 top of magnetic suspension piggyback pod 19 encircles two hanger rails 8 respectively, and hanger rail is embedded in the piggyback pod.The middle part of magnetic suspension piggyback pod 19 is equipped with one group of actuating unit, and this actuating unit of this actuating unit is linked to each other by wheel shaft 26 with drive motor 22 by drive wheel 18, is fixed on the power bulkhead 27.The termination, top of power bulkhead 27 is safe piston shoes 28; made by elastic metallic, its effect is when between attraction permanent magnet 23 described later and the spill hanger rail 8 during operational failure, because safe piston shoes 28 are arranged; vehicle still can rely on piston shoes 28 to slide on hanger rail 8 tops, and the protection train does not derail.Drive wheel 18 operates in the grooved tracks 32 of hanger rail 8.Piggyback pod also accommodates vehicle power and inverse control system, because vehicle power and inverse control system are present electric locomotive institute general-duty device, and is not discussion emphasis of the present invention, so does not mark in the accompanying drawing.Drive wheel 18 actuating units such as grade in the above-mentioned piggyback pod are installed in the middle part in magnetic suspension compartment.
See also Fig. 5, for the present invention suspend the vehicle piggyback pod the air gap position-limited wheel and attract permanent magnet and the marriage relation of track.Air gap position-limited wheel 24 is positioned at the two ends of piggyback pod 19, this air gap position-limited wheel 24 and above-mentioned drive wheel 18 in-lines.Air gap position-limited wheel 24 is for preventing that aftermentioned from contacting between attracting permanent magnet 23 and hanger rail 8 contacting, and also has the function of air gap position-limited wheel 24 concurrently with regard to function drive wheel 18.Air gap position-limited wheel 24 also is to be fixed on the bulkhead 27 of piggyback pod 19 by wheel shaft 31, and also is operation in the grooved tracks 32 of hanger rail 8.
See also Fig. 6, shown the attraction permanent magnet of maglev vehicle of the present invention and hydraulic actuating cylinder connection state and with the marriage relation of hanger rail.Hydraulic actuating cylinder 25 is arranged between drive wheel 18 and the air gap position-limited wheel 24.Attracting permanent magnet 23 is two, attract permanent magnet 23 to can be solid permanent magnetism, superconductive permanent-magnet or electromagnetism, be separately fixed at substrate 29 left and right sides that the magnetic conduction steel plate is made, with respect to 8 two sides of hanger rail, the installation that attracts permanent magnet 23 be wherein one relative with hanger rail 8 be the N utmost point, what another was relative with hanger rail 8 is the S utmost point.The bottom of substrate 29 is fixed on the lifting hydraulic cylinder 25, and the effect of hydraulic actuating cylinder 25 is according to the big minor adjustment attraction permanent magnet 23 of load-carrying of train and the working gas gap between the hanger rail 8, to increase or to reduce permanent-magnet attractive power.Work institute crack generally remains on 5-60mm.
The principle of work that rail permanent magnet of the present invention attracts to suspend with guideway-driving skills art system is, when empty wagons moves, reduce to attract the height of permanent magnet by hydraulic efficiency pressure system, with increase its with the spill hanger rail between air gap, the minimizing attractive force promptly reduces the pressure of air gap position-limited wheel.This moment the air gap position-limited wheel pressure F 1Equal to attract the gravitation F between permanent magnet and the spill hanger rail to deduct empty wagons deadweight F 2After pressure, this pressure F keeps train to be in the safe pressure of suspended state, its expression formula is F=F 1+ F 2When loaded vehicle moves, raise to attract the height of permanent magnet by hydraulic efficiency pressure system, with reduce its with the spill hanger rail between air gap increase attractive force.Its gravitation increase value F 3Relevant with the weight of the contained object of train, its expression formula is F=F 1+ F 2+ F 3When train is turned, centnifugal force staggers train and spill hanger rail, attracts to have produced between the gravity of the gravitation of permanent magnet and train the angle less than 180 ° this moment, according to parallelogram law, its resultant direction is opposite with the centnifugal force direction, and this power constraint train can not derail.When unsafe condition occurring, the piston shoes of piggyback pod play safety effect.
The present invention compared with prior art has the following advantages:
1) cost is low, is equivalent to 1/5 of German TR series;
2) energy-conservation, be equivalent to 20% of German TR series;
3) transport power is big, is equivalent to 10 times of German TR series, but gets final product again shipping of passenger traffic;
4) train is from heavy and light, and 0.7 ton/meter is that German TR series train is from 1/3 of weight.
