Description

Improved train railway

Technical field: the technical field under it is train, railway.

Background technology: because the existing train lengths such as restriction of power generally are not very long, the electric motor car group because of cost height, operating expenses height at a high speed etc. also shorter.Existing train majority is made up of locomotive and railway carriage, and power is on locomotive, and whole train drives operation by it, and locomotive is to the frictional force maximum of rail, and every joint railway carriage all will have the tensile property that can bear the hauling capacity of a locomotive etc.The rail joint place only depends on the both sides steel plates to connect, and the front and back rail is laterally to disconnect, wheel through out-of-date can the bump rail head, rail face width 70mm, wheel carrying face width 100mm, the abrasion of rail face is just changed during to setting or is scrapped rail.

Summary of the invention: the purpose of this utility model is improved the train railway, comprise the light train railway, freight train and the very long or suitable lengthening of fortune passenger plane car team Che Kejia, improve every time freight volume of train, reduce cost, increase benefit, improve the railway performance, train is more steady during through the rail joint place, improves rail application life, and relayable rail utilizes again.Existing train railway is carried out renovation and utilization.

The novel technical scheme of this reality is the design over long train, steady durable railway.Above technology can be used for existing train railway is comprised that light train railway such as subway etc. transform.

Over long train is the train that its length or joint number surpass existing locomotive train or passenger traffic EMUs.As the dynamic over long train of 1. every joints, 1.1. the self-driven over long train of every joint, the power of every joint mainly drives self, and have suitably more than needed, headstock is more than needed should be some more, it mainly is that situation that minority power gone bad suddenly etc. is arranged in tackling on the way that part more than needed is done to incline with fullying, and power can be used all kinds, as internal combustion engine, motor etc.All dynamic Control concentrate in the headstock OPS, power on the headstock install can be with existing locomotive similar, the power of railway carriage can be positioned on and turn on the stand, drives wheel shaft by machine driving such as reducers, the driving control of train and existing similar.Because every joint is all dynamic, do not resemble existing railway carriage and want to bear transmission locomotive gross tractive effort, railway carriage can be lightly, and promptly light-duty compartment can adopt light-duty hook, light-duty compartment beam, lightweight truck etc.1.2. major-minor power over long train, existing locomotive train can be transformed into the major-minor power over long train that can suitably extend, it is locomotive+auxiliary power railway carriage, its auxiliary propulsion-unit control device for use is positioned in the locomotive driving chamber, and it is synchronous with railroad traction control, by the unified operation of driver, the auxiliary power railway carriage, promptly turn to and set up auxiliary power assistance driving self on the stand at existing railway carriage, auxiliary power is to be not enough to drive self power of (deadweight+load-carrying), only plays assistive drive, and how many its size decisions can will have the train lengthening now, can drive 50% of self gross weight as auxiliary power, then train can be lengthened to 1 original ÷ (1-50%)=2 times.2. series connection over long train: be with several trains train of operation together that is together in series with (artificial and automatically) synchronous control system.Comprise that synchronously synchronization line is sailed and synchronous brake.Travel synchronously and guarantee synchronously by rank rear by telecommunication or (two between row) synchro by first driver.Synchronous brake is generally finished by prostatitis driver control or synchro.2.1. locomotive train+short synchronously train (visitor, goods) (group) over long train.Short train is made up of (middle low-power) synchronous locomotive and existing railway carriage.2.2. existing locomotive train series connection over long train.3. shipping EMUs over long train and existing passenger traffic EMUs are similar, but long, can not be at a high speed.

Steady durable railway, the railway that constitutes by steady joint and durable rail.

Steady joint.The wrong linking of rail hand-deliver of joint; Or there is auxiliary smooth excessiveness face the orbital plane both sides; Or preceding two kinds combination, do not clash into (or hit than jog) rail head in the time of just guaranteeing wheel through the joint.The staggered orbital plane that is connected in joint, promptly when gap at joint was maximum, forward and backward orbital plane (as each half width) also had been cross-linked or also is being connected with excessive face.Excessive (track) face of joint (orbital plane) outside widening is because of wheel carrying face width 100mm, track face width 70mm, so excessive track face width≤30mm in the outside, and two ends (or an end) has and downward-sloping draws the face of connecing so that smooth excessiveness, and it can be independent, is assembled in seam crossing then; Also can and play gusset piece with the welded together of one of rail.The excessive face of joint orbital plane inboard wheel flange, it than the height of the low flange of orbital plane and two ends downward-sloping so that wheel flanges than smooth excessiveness.No matter adopt any or wherein possible combining structure, all the joint with the steel plate holder, and joint snaps onto on the supporting plate, two ends of bearing plate snaps onto respectively on the cement pillow, and is more steady in the time of allowing wheel through the joint like this.

Durable rail, under the prerequisite that satisfies the bearing technology requirement, the rail iron rail level outside widen as best one can (≤30mm) rail, or it supports gradient K and suitably strengthen, rail bottom width B, the thick D of waist also suitably (laterally) strengthen.This design can be to renovating with the rail of crossing, promptly renovate durable rail, the rail surface wear is during to setting, (do railway outside the) repaired (time spent is done the railway medial surface again) on one side, and another side wide a little (≤30mm) and encase unworn root limit (doing the railway lateral surface), and rail sticks up a (half of wheel bearing surface cone angle) thickening towards outer skew back, allows after the renovation more solid and more wear-resisting.The joint of durable rail can adopt steady joint and constitute steady durable railway.

Compare with existing train railway, the utility model has the advantages that (1) over long train can improve the conevying efficiency of every time train freight volume and railway greatly, remote control series connection over long train is on the passenger traffic peak or goods several joints that for a long time train extended, tens joints up to a hundred also can once drive away, and it need not dote on big locomotive, large-sized power machine etc.The self-driven over long train of every joint, do not resemble the restriction that existing train will will be mated by railroad traction and railway carriage joint number, how long, how much, train can suitably will save all right, and do not influence speed of a motor vehicle train number, be convenient to train scheduling, or else headstock and railway carriage need to bear the performance of locomotive gross tractive effort, therefore structure, deadweight can be more lightly, capable of reducing energy consumption, it does not have present huge locomotive to give the huge frictional force F (equaling the hauling capacity of a locomotive) of rail, and F and the frictional force F of railway carriage to rail ₁Oppositely, n/one (n has the train joint number now) that its every joint all almost has only F for the friction of rail, and all in the same way, so can allow rail abrasion than present overflowing, prolong application life.The design also can transform existing train lorry and passenger vehicle (except that the electric motor car group).(2) steadily excessive rail joint can allow train driving not have (or reducing greatly) to impact, and is more steady, takes advantage of seat more comfortable, helps train speed raising.Alleviate or eliminate the bump of train wheel, reduced noise, reduce the damage of train part and rail rail head.(3) the rail face is widened the life-span that can improve the rail wheel, reduces and changes rail, and the manpower and materials of wheel reduce the transport capacity that the number of times of changing rail helps improving railway.(4) durable rail can not only improve performances such as rail application life, reduces the cost of system rail, reduces the expense of railway, and rail scrap can also be utilized again.The design also can transform existing train railway, improves its conevying efficiency and operating benefit greatly.Very huge social benefit of the present utility model and economic benefit will be!
