Description

Train is over long distances, heavy grade, the method for protecting on road surface

Technical field

The present invention relates to a kind of trains over long distances, and how heavy grade, descending and upward slope road surface when driving, guarantee train, At high speed, at full capacity, the technology of safety and stability traveling, it exists to train, long range, heavy grade, on road surface, improves train speed Degree increases transport capacity, guarantees that transportation safety has extremely important effect.

Background technique

Due to having more than the huge drop of 5000m or more between the western and eastern, China, with the continuous development of railway construction, The length on railway gradient road surface is increasingly longer, and in central and west regions, the gradient exists, the heavy grade road surface of (6 ‰ -30 ‰) account for 85% with On, there have been a problems very serious in this way, because train can generate automatic add on heavy grade descending road surface when driving Speed, such as: train will automatically speed up 0,69 kilometers in every 1 second on 20 ‰ descending road surface, it is therefore necessary to by reducing speed, Freight volume is reduced, to guarantee the safety of train, if while in the brake system failure train meeting of heavy grade upward slope road surface There is inverted running, will be caused a significant threat to subsequent train, in order to guarantee train in heavy grade descending road surface and great Po Degree can be safely operated on upward slope road surface, there is an urgent need to invent new brake technology and building security support facility, for fire The safe operation of vehicle provides guarantee, thoroughly solves the weight that train generates in long range, heavy grade descending road surface and upward slope road surface Big security risk.

I has invented train over long distances by long-term research, and heavy grade, the safety protection technique on road surface, it is to pass through Increase the stopway that band 15 ‰ goes up a slope in railway line, train is laid down on heavy grade road surface by it because self weight and difference in height produce Raw potential energy guarantees the safety of train, while by building helistop near stopway, guarantee to repair rapidly therefore Hinder train.

Summary of the invention

It is very more on Southwestern China Railways In Northwest China heavy grade road surface, wherein 6 ‰ or more heavy grade road surface accounts for sum 85% or more, the gradient is 10 ‰ -30 ‰, and length is many in tens kilometers up to a hundred kilometers have, since train is long in heavy grade When apart from descending road surface, uplink is sailed, it is necessary to guarantee transportation safety by slowing down and reducing trailing weight, therefore exist at train Train speed is improved on heavy grade road surface and increases the bottleneck of transport capacity, and there are also trains in operation if there is big over long distances It has to carry out continuous cyclic brake when gradient road surface, since continuous brake block can heat up to reduce after multiple friction Coefficient of friction causes Train brake power to reduce when brake force reaches a low value, will be unable to control the speed of train to fire The safe operation harm of vehicle is very big, and in order to solve this problem I have invented a kind of multifunctional train compartments, it can pass through Regenerative Braking Technology makes train have powerful brake force on heavy grade descending road surface, while the electricity of recycling power grid can also be sent Enter upward slope power grid be upward slope road surface on traction motor power such train go up a slope when just have powerful tractive force, therefore energy Enough make train on heavy grade ascents and descents road surface can, at full capacity, run at high speed, foregoing invention makes train in heavy grade There is powerful brake force on descending road surface, has powerful tractive force on heavy grade upward slope road surface, moreover it is possible to which train is produced on descending road surface Raw potential energy is converted into electric energy, but how to guarantee that there is also defects on transportation safety, thus in order to improve the relevant technologies I Safety protection technique of the train on heavy grade, long range road surface has been invented again.

Invention be first on the descending road surface of heavy grade, from highest point to one recycling grid line of minimum point design, The compartment of axle driven generator is largely used in manufacture, is consolidating for traction motor power supply saving battery for each column train configuration two Determine compartment, there is heating in each the inside made of heat-resisting material of installation one before each wheel on the compartment with generator The seal box of resistance, suitable for reading to connect with high steam pressing tube, lower mouth alignment wheel and track, in the gradient (5 ‰ -30 ‰), length 20 is public In more than, heavy grade descending road surface on, all build a recycling grid line from highest point to minimum point, connection recycling grid line One 2 kilometers or so of isolation power grid is all built in place, wherein grid line, and grid line is isolated, and is recycled grid line, is all used insulation material Material is kept apart, but the local pantograph connected between them is wanted to pass through, and repairs one below isolation grid line Rail road surface with 2 ‰ descendings.

New Regenerative Braking Technology can be carried out after the completion of above-mentioned preparation, specific method is；

(1) increase on descending track and build stopway

(2) also increase on upward slope track and build stopway

(3) helistop is built in the place close to stopway

(4) substation is being built close to the place of recycling power grid

I am train in long range, heavy grade descending road surface and long range, the method for operation on heavy grade upward slope road surface below It is specifically described.

1. building stopway on descending track

In order to enable train not only to have powerful brake force on the heavy grade descending road surface of (10 ‰ -30 ‰) but also want More safety and stability uses new Regenerative Braking Technology in invention, is exactly the highest in heavy grade descending surface railway track Above point to the minimum point of railroad track, a recycling power grid is individually built, recycling power grid is using original grid line, only Recycling power grid and grid line are disconnected in highs and lows with insulating materials, but pantograph is wanted in grid line and to return It is smoothly current to receive the place connected between grid line, recycling power grid so just becomes an abortive haul without any electric energy, fire Vehicle is to draw train running by the fixed compartment of battery powered 2 section, then by the electrical power generators on brake equipped cars big The potential energy that gradient descending road surface train generates is converted to electric energy by regenerative braking, then to build close to the place of recycling power grid The traction motor that the grid line that upward slope is sent into after the electricity regulation of recycling power grid is upward slope is powered by it by one substation, The electricity of traction motor consumption is equal when the electricity and train issued according to (law of conservation of energy) train descending goes up a slope, in this way The energy consumption of train flat pavement running can complete the traction work on heavy grade upward slope road surface, while can also be other use electric energy Electric unit power supply.

Train can be made to have powerful brake force on heavy grade descending road surface using invention above, but if regeneration is made Train will be out of hand when dynamic failure, hidden due to not having evacuation facility that can generate great safety to entire transportation route Suffer from, in order to solve this problem I am according to the different situations of every route, and on descending road surface according to the speed of train, the gradient is long Degree, difference multiple stopways are set as the case may be respectively on different routes, stopway entrance and descending track Main line connection, outlet are also connected with the main line of descending track, and stopway and main line are built side by side, and stopway is from entering Mouth will have 15 ‰ upward slope track to top, lay down train after the potential energy that descending track generates with it, train is made to be parked in parking Be below arc at the top of stopway be descending track with a slope on road, just pass through when train will reply operation top curve from Stopway outlet enters main line, since train is the fixation compartment traction train fortune with two whose power supplieds in big descending track Row, therefore being drawn with it can be extremely difficult when train passes through upward slope arc, therefore to prepare a traction locomotive and help train Entering descending by arc track makes train export injection main line from stopway.

Pass through tele-control system if when train regenerative braking breaks down in this way to remove, or by manually removing Road makes the train main line that de-orbits enter stopway, then the upward slope of stopway 15 ‰ is recycled to lay down train in downhill path The potential energy that face generates makes train be parked in stopway, then transports maintenance personal and maintenance package using helicopter and carries out to stopway It repairs, train is pushed through using traction locomotive after the completion of train maintenance and enters descending track at the top of the arc of stopway by stopping Lane outlet injection main line continue to run, this ensures that descending track whenever the train of full line can Enough continual safety operates normally.

2. increasing on upward slope track and building stopway

It, be close to recycling in order to enable train to have powerful tractive force on the heavy grade upward slope road surface of (10 ‰ -30 ‰) A substation is built in the place of power grid, and the grid line that upward slope is sent into after the electricity of recycling power grid is regulated and controled by it is the traction gone up a slope Motor, according to (law of conservation of energy) train, in descending, electricity and the train traction motor when going up a slope are consumed Electricity it is equal, the energy consumption of such train flat pavement running can complete the traction work on heavy grade upward slope road surface, invention above Train can be made to have powerful tractive force on heavy grade upward slope road surface, but if when heavy grade goes up a slope train traction motor When failure runs out of steam, train just will appear counter motion, and great security risk can be generated to entire supply line, in order to Solve this problem I on upward slope road surface according to the speed of train, the gradient of track, length is different, in different routes respectively Distance respectively different multiple groups stopway is set, one group of stopway be two one of them build up 15 ‰ gradient, another is built At identical with the main line gradient, they all build the side of main line in, if train trailer system failure train loses control When producing existing counter motion, just by remotely control remove or manually remove make failure train de-orbit main line entrance 15 ‰ upward slope track is parked in failure train on stopway using the potential energy that upward slope track lays down train, while close below The train of accident train running will not have acclive stop by automatically controlling to remove or manually remove to enter in advance from entrance yet Lane avoids accident train, is thus avoided that car to car impact accident occur.It is just led using locomotive after the completion of the maintenance of failure train Draw, reenters main line from outlet along gradient road surface and put into operation.

And below close to there is the train of counter motion failure train running, dispatcher first will be removed by automatically controlling Either so that train is detached from main line by manually removing, enters the parking that stopway waits failure train to enter 15 ‰ from entrance It reenters main line from stopway outlet behind road and continues to run, this makes it possible to the continual peaces of train for guaranteeing full line Full orderly function, if using above-mentioned technology arrange rationally its safety and conevying efficiency can than the train of flat pavement running also than Height can thoroughly solve the problems, such as that train can not travel at full capacity at high speed in heavy grade descending and upward slope road surface.

3. building helistop in the place close to stopway

It repairs, is just allowed for maintenance if building stopway in railway line and accident train being parked on stopway Personnel, maintenance of equipment, maintenance and repair parts transport to rapidly stopway, but to be all that mountain area is repaired the roads extremely difficult on all heavy grade road surfaces, Therefore it reaches the scene of the accident in order to transport maintenance personal and maintenance of equipment as early as possible and to build helistop near stopway, this Sample had just not only saved road construction fund but also had improved maintenance speed, while can also pick people on duty on stopway on time using it The road Gong Ban personnel are on and off duty.

4. building substation close to the place of recycling power grid

Train is one since the effect of speed and weight can generate very big potential energy when heavy grade descending road surface is run A resource that can generate a large amount of electric energy, but these valuable resources are relevant due to not inventing in the world for a long time Recovery technology is all by slatterning in vain, and the present invention seeks to fundamentally solve this problem, it is first in great Po It spends on the rail road surface of descending and builds an independent recycling power grid, a substation is built near recycling power grid, then train Recycling power grid is sent by the electricity that regenerative braking issues on descending road surface, the electricity on upward slope road surface is sent into after regulating and controlling using substation Net is the traction motor power supply gone up a slope, and is disappeared according to law of conservation of energy descending regenerative braking electricity and upward slope traction motor The electricity of consumption be it is identical, we are not only to recycle the electricity of power grid to have found electricity consumption outlet in this way, but also can be by upward slope Power grid power supply can reduce the costs of a large amount of construction power transmission lines, realizing optimum organization keeps railway transportation more scientific and reasonable, Transportation cost can be greatly lowered, while the electricity for recycling power grid can also power for other electricity units.
