Abstract
The suspension high speed railway and the city suspension railway are overhead railway for suspending train, and the overhead railway is laid on the railway frame supported by the railway piles erected on the ground. Suspending train can lower the gravitational center of the train and this makes it possible to raise train speed to reach the speed level of magnetically suspension train. The present invention has simple structure, low cost and saving in earth.
Description
Technical field
Suspension type high speed railway of the present invention and city suspension type railway and train vehicle frame transfer device belong to traffic infrastructure and field of vehicles.
Technical background
Current international high speed railway has magnetic suspension high speed railway and wheel-track type high speed railway.Shanghai reaches 430 kilometers by the magnetic suspended railway speed per hour that Germany builds.But cost is also expensive especially, invests 300,000,000 yuan of Renminbi for every kilometer.
Summary of the invention
Traditional railway not too adapts to the needs of contemporary rapid economic development because speed is slower.21 century should be the century of high speed railway great development.But high speed railway will develop on a large scale, must reduce cost significantly, otherwise great development is difficult.The objective of the invention is to attempt to invent the cheap especially again high speed railway of a kind of brand new cost.
Title of the present invention is suspension type high speed railway and city suspension type railway and train vehicle frame transfer device.The suspension type high speed railway is identical with city suspension type railway structure.The former is a heavy railway, is applicable to long-distance passenger and freight transportation; The latter is a light railway, is applicable to urban public transport.Suspension type high speed railway and city suspension type railway are to comprise overhead track and reversal of the natural order of things train two parts composition.Because of the low latitude of rail bracket, so claim overhead track at nearly ten meters or more than ten meter above ground level.Again because the train that hangs on the track is inverted, and promptly vehicle frame is last, and the compartment occupy the below of vehicle frame, so claim the reversal of the natural order of things train.Specifically be that the compartment hangs on the transverse axis with the vehicle wheel frame at vehicle transverse axis two ends in orbit.If the compartment of conventional train is likened to " my god ", vehicle frame liken to " ", the reversal of the natural order of things train can be described as the change of conventional train being turned over " my god " cover " ".
Overhead track by buried underground ferro-concrete track stake, connect before and after the ferro-concrete longeron, frame of two track stakes at the reinforced concrete girder on two track stakes of front and back, be embedded in fastening device for rails on the reinforced concrete girder, connect about three road ferro-concrete crossbeams, the connecting reinforcement concrete girder lower end, upper end of two track stakes connect the ferro-concrete oblique volumn supporting of track stake and longeron junction and be laid on rail on the reinforced concrete girder etc. and form.4.5 meters above ground level of ferro-concrete longeron, it both played stabilization to track stake, was again the safe guard beam of railway.The first road crossbeam is embedded in underground, a little less than ground; The second road crossbeam should be above ground level more than four meters; The top of two track stakes about the 3rd road crossbeam connects.Track stake is an integral body from bottom to top, because of the structure difference, can be divided into three sections again: first section is embedded in undergroundly, and the cross section is rounded; Second section is girder with down to ground, and the cross section is " protruding " font of horizontal shop, the lower part reinforcement placing concrete girder of " protruding " word, and the first half extends upward, and should exceed about one meter of vehicle frame, is the 3rd section, and the cross section is rounded.
In order to reduce the pressure of wheel unit area to track, also, both needed wheel many for the ease of the assembling compartment, need the car transverse axis many again, therefore a car is not only respectively adorned two pairs of wheels in front and back, and the middle part will refill several to wheel.Reversal of the natural order of things car two-wheeled spacing must be greater than box width, otherwise wheel is just hung less than on the track.
The part of reversal of the natural order of things train is the reversal of the natural order of things car, the reversal of the natural order of things car be by the car transverse axis, be contained in the transverse axis two ends wheel, be welded on last item steel plate on a pair of transverse axis, be welded on spring on the last item steel plate, be welded on stage clip steel plate on the spring, be welded on many three angle steel on the stage clip steel plate and two oblong steel bushings making of oval steel, cover two ends, the three angle steel left and right sides on two steel bushings, the two ends, the backing steel left and right sides, compartment of trapping.On a plurality of backing steel, be that the skeleton of car wall is manufactured the compartment with the round steel on two limits of steel bushing.Steel bushing connects into a car load with vehicle frame and compartment and since vehicle frame last be a reversal of the natural order of things car.Many reversal of the natural order of things cars are formed the reversal of the natural order of things train.
Locomotive is the important component part of railway.Suspension type high speed railway and city suspension type railway all can use traditional wheeled locomotive, for the speed that improves locomotive also can be used the screw propeller locomotive.Because be subjected to the restriction of gauge, the blade radius is shorter, is a no small defective, screw propeller can only play the shop and help effect.A locomotive can be adorned one little one big two driving engines, and puffer ranks forefront, and drives the screw propeller rotation, after big driving engine leans on, and the drive wheels rotation.Also can use the twin screw locomotive, front engine drives the rotation of trailed model screw propeller, and rear engine drives the rotation of pusher type screw propeller.The trailed model screw propeller is contained in the locomotive back, promotes locomotive and advance, be pusher type screw propeller.
The conventional train locomotive engine can the direct drive wheel revolutions above wheel.Reversal of the natural order of things train locomotive driving engine is positioned at the wheel below, and the girder of rail and shop rail is arranged under the wheel, influenced by it, and locomotive can not the direct drive wheel revolutions.One of method of driving is to adopt two-wheel one wheel indirectly.Two wheels that diameter is isometric side by side, with the round steel of more than ten about 30 centimeter length, 1/2 place at the two-wheeled radius is welded into one with the two-wheeled ring-type, is contained in an end of transverse axis.One is an off-side wheel, claims rail wheel, and another is a nearside wheel, claims driven wheel.The transverse axis other end will be adorned two-wheel one wheel equally.When engine drive driven wheel when rotation that is positioned at the below, driven wheel whenever revolves and turns around, the rail wheel circle that just orbits.For the ease of the rotation of engine drive driven wheel, the motor car should be done widelyer as far as possible.Two-wheel one wheel has been arranged, and the locomotive of reversal of the natural order of things train just is not difficult to have made.
The reversal of the natural order of things train in high-speed cruising, wheel and rail head collide vibrations bigger.The subway that Beijing is newly-built, rail head seldom, but complete obiteration not yet.In order fundamentally to address this problem, can adopt the combined type rail joint.The joint of rail one end has only left half leaf, lacks right half leaf; The joint of the other end has only right half leaf, lacks left half leaf., a left side half leaf of rail joint, just in time the right side half leaf with another rail joint is harmonious.In the joint, lower slightly several millimeters of rail level has downward gentle slope, and gentle slope is upwards also arranged, and the gentle slope end and rail level are flat.Wheel can not collided with rail head by the combined type rail joint.
All there are many station tracks in suspension type high speed railway station and city suspension type railway master station.Train enters another station track and adopts shiftable track from a station track.The centre portion of every track is a trapped orbit, and it is shiftable track that two ends respectively have a bit of, is supported by movable supporting frame, and support dress wheel is used driven by power, can travel on hard ground.Two shiftable track joint joint anchor fittings.Trapped orbit joint and shiftable track joint are respectively half-moon-shaped joint and semi-circular joint.
Suspension type high speed railway and city suspension type railway all can be constructed to two-layer up and down, and the upper strata is kept supplying the ranks car and travelled, and lower floor travels for down train.Only need with the ferro-concrete track stake build deeplyer, thicker, higher, increase on track stake top and to build the top bars concrete girder, at girder shop rail, increase again and build the ferro-concrete crossbeam one, can carry additionally upper strata reversal of the natural order of things train.If build way and double-layer suspension type high speed railway, two-way lower floor travels for the uplink and downlink goods train respectively, travels for the uplink and downlink passenger train respectively in two-way upper strata.
To the transition of suspension type high speed railway, the size in two kinds of railway passenger and freight compartments preferably equates for the ease of traditional railway.Because suspension type high speed railway gauge greater than box width, is necessary for the suspension type high speed railway and determines gauge.This is the part major issue, once determining permanency.City suspension type gauge and the compartment fixed whole nation not of uniform size is unified, could determine voluntarily.
City suspension type railway is not only applicable to the suburbs, city, and can the entering part urban district, also can enter the boder district, center.The suspension type railway that enters the urban district should be built top, viale both sides, for example top of slow lane in.Track stake can play hard shoulder.The station should be built in the expropriation of land of both sides, street.But station platform should be built the top, footway in.Should build overline bridge by the station to platform.City suspension type railway should be higher than People's Bank of China's overpass.
If the suspension type high speed railway traditional railway will occur to the transition of suspension type high speed railway can be successful.If the suspension type high speed railway can not be formed the unified railway network with traditional railway, be very disadvantageous.The method that solves this difficult problem is to adopt train vehicle frame transfer device.This train vehicle frame transfer device comprises reversal of the natural order of things train conversion vehicle frame, conventional train conversion vehicle frame, reversal of the natural order of things train and compositions such as dual-purpose compartment of conventional train and liftable track.Reversal of the natural order of things train conversion is all to entangle to transverse axis from three angle steel with the two ends that two steel bushings of being made up of four limits that the rectangular steel of certain thickness and width is done will hang upside down vehicle carriage with vehicle frame, and the electronic colligator lockhole formation of similar spring lock lockhole is respectively welded at four angles bottom steel bushing again.(electronic colligator lock can be locked two buttons).The conventional train conversion is to remove traditional vehicle from its compartment with vehicle frame, replaces dark about about 40 centimetres recessing, and recessing is suitable for reading wide, and bottom area is slightly larger than dual-purpose compartment bottom area.At bottom land, rice in 30-40 is adorned a wide height and respectively is the steel bar about 10 centimetres, shock mount between the steel bar.Lorry is then removed steel bar and spring from.Constitute at the moving colligator lock of the high about 30 centimeters pick wall distribution of recessing two walls in addition.Reversal of the natural order of things train and the dual-purpose compartment of conventional train are that reversal of the natural order of things car compartment is made and the disjunct independent compartment of vehicle frame, the electronic colligator lock that equates similar spring lock dead bolt earlier at the corresponding number of the electronic colligator lockhole of car body top perimeter mounted and vehicle frame, high nearly approximately 30 centimeters of two walls are made the colligator lockhole that equates with the phase-locked cooresponding quantity of the electronic colligator of recessing in the compartment again, promptly constitute dual-purpose compartment.
When concrete enforcement vehicle frame was changed, the conversion of reversal of the natural order of things train should be combined as a whole earlier with vehicle frame and dual-purpose compartment.If on conventional train is changed with vehicle frame, change, the conventional train conversion be sailed on the liftable track with vehicle frame, will hang upside down the top that train sails for the liftable track again.To handle the liftable track earlier and move forward and backward again rising slowly, make dual-purpose compartment enter the recessing notch and also stop lifting in good time, open the electronic colligator lock of reversal of the natural order of things vehicle carriage this moment earlier, dead bolt is retracted in the lock, promptly conversion separates with vehicle frame and falls in traditional recessing with the reversal of the natural order of things train in dual-purpose compartment, electronic colligator lock on the traditional vehicle cell wall is relative with dual-purpose compartment lockhole at this moment, and electronic colligator lock is locked, and the vehicle frame conversion is promptly accused and finished.When dual-purpose compartment again when reversal of the natural order of things train conversion is changed with vehicle frame, the conventional train conversion will be driven on the liftable track earlier with the dual-purpose compartment on vehicle frame and the vehicle frame, to hang upside down the train conversion again and sail for liftable track top with vehicle frame, handle the liftable track and it is moved forward and backward and blow slowly rising this moment, hit into colligator lockhole until the colligator dead bolt, this moment, electronic colligator lock was only locked a button, locked second button again, then reposition is fallen in the liftable track, the vehicle frame conversion is promptly accused and is finished.
What is a high speed railway? does the suspension type railway is had ready conditions become high speed railway?
The railway of speed per hour above 300 kilometers can be called high speed railway in general.High speed railway will possess two essential conditions at least: the one, and high-speed locomotive be arranged and be suitable for the passenger and freight car compartment of high-speed cruising; The 2nd, to guarantee the safety of high-speed cruising.The former accomplishes easily, can not make for the moment, can buy to other country; Guarantee that safety then is difficult to accomplish.Therefore, as long as can guarantee the safety of high-speed cruising, just possessed the condition of high speed railway basically.The below that the reversal of the natural order of things train occupies track, center of gravity are negatives, and it has overcome the biggest obstacle of traditional railway speed-raising, train is absolutely not to derail, topples from the track top, because wheel is stuck on the track, train can not fall down between two tracks again, should be ultra-safe again.If can be that one two vertical three horizontal diagonal braces are built strongly fortifiedly with suspension type railway framework, the train of the speed per hour of passing through more than 300 kilometers, the suspension type railway just can be described as high speed railway.
Suspension type high speed railway and other high speed railway which advantage of having compared?
1, suspension type high speed railway cost is cheap especially, and the required raw MAT'L of this railway is steel, cement, sand, stone etc., and these thing prices are low, and the Railway Investment of being built is very few certainly; Suspension type railway land occupation is very few, can save a large amount of fees paid for taking rural lands; The suspension type railway is easy to construction, and the duration is short, can save a large number of engineering funds.In a word, the suspension type high speed railway is cheap, and every kilometer cost may only be one of tens molecules of every kilometer cost of magnetic suspended railway, the highlyest also can not surpass 1/10th.
2, suspension type railway land occupation is few, can save the territory.Magnetic suspension and wheel-track type railway all need full-overpass totally-enclosed, take a large amount of soils, and the suspension type railway mainly is that station and track stake take a small amount of soil, compares with magnetic suspension wheel track formula, can save a large amount of territories, and longitudinal and cross beam also only blocks some sunlight.Arable land in the railway framework still can be cultivated.The territory is the most valuable resource, and the territory is basis of Wanyuan.Do not have the territory, where have hydrocarbon resources; Do not have the territory, where have water resource.At all times, most wars are in order to fight for the territory.As seen it is how important saving the territory.Saving social benefit and the economic benefit that the territory produced can not weigh with money.
3, the suspension type railway is easily built, and construction is fast.One two vertical three horizontal diagonal brace should be able to batch production production and mechanical execution, and buried track stake neither what difficult matter.Compare with magnetic suspension wheel track formula, the duration is wanted much shorter.
4, suspension type disaster relief campaign of railway evil ability is strong.Magnetic suspension and wheel-track type railway all have stronger anti-disaster ability.The suspension type railway is stood high above the masses, and big flood dashes and do not collapse, and mud-rock flow also is difficult to crush bury, especially big blizzard, and the reversal of the natural order of things train also can normally move.The anti-disaster ability is stronger.
5, the suspension type railway objectively can play full-overpass fully enclosed effect, and is but totally-enclosed better than full-overpass.It does not have totally-enclosedly to give near resident the particularly production that brings of peasant and inconvenience in life.
6, the suspension type railway does not need roadbed, and what influence frozen soil does not have to the suspension type railway.The suspension type railway has solved the difficult problem that railway is repaiied in the tundra actually.This is unexpected results.
7, if the suspension type high speed railway is can be successful, and it can do passenger traffic, can do shipping again, and magnetic suspension has only passenger traffic, does not have shipping.The goods train load carrying ability is big, " suspend " to get up not to be easy thing.Even done shipping,, there is not realistic meaning if freight charges are very high yet.
8, suspension type railway cost is low, and service expenditure is also low naturally.Magnetic suspension and wheel-track type want outer state artificial, and maintenance and parts are all wanted outer compatriots, and it is high that expense is wanted naturally.
9, the required foreign exchange of suspension type railway is very few.The Shanghai magnetic suspension is invested 10,000,000,000 yuans, and whether major part will be used exchange payment in this huge sum of money.Compare with magnetic suspended railway, the suspension type railway is saved foreign exchange does not have query.
Certainly, the suspension type railway also has the defective that its birth just brings.For example, it can not show a candle to the magnetic suspended railway noise little and vibrations low.
