Abstract
The utility model discloses a rail vibration-reducing connecting internal board having the supporting function, solves the vibration and noise caused by rail joints during the operation of wheelrail railways and ensures the operational safety. The rail vibration-reducing connecting internal board has an L-shaped section in the middle part, an internal board head in the upper part, and an internal board bottom in the lower part. The head, the waist and the bottom of the internal board are integral. The delta semi-transverse rail connection design for the rail surface resolves the vibration and noise produced by the wheels of a train when passing the rail joints, prolongs the service life of rails and relevant parts and components. After the processed rails are fixed via bolts in line with the original connection type, the upper surface of the rails will form delta transverse non-penetrating joints, and the lower surface of the rails will form the supporting structure similar to original rails to ensure the safe and stable operation of trains. The board has a greater thickness in the waist part than existing rails and thus has the ability to bear the gravity load of trains independently.
Description
Technical field the utility model relates to and is used to take turns a kind of structural member that rail railway gets on the right track and connects, and especially a kind of steel rail vibration damping with support function connects inner splint.
The track connected mode that background technology is taken turns on the rail railway at present and adopted is that the one by one head with holes rail of section for " worker " font connected, and uses two steel clamping plate that match with rail " worker " font waist both sides to realize with bolton then.The variation owing to temperature causes that rail expands with heat and contract with cold under the natural conditions in order to satisfy, and its length is changed, and when connecting track, need be at joint and reserves certain slit to guarantee that rail can freely stretch with temperature Change along its length.
When train driving during to place, this slit, wheel can produce " moment is unsettled " in theory, spring on the vehicle wheel frame and wheel weight form downward making a concerted effort, owing to the support that loses rail this moment " moment is unsettled ", make wheel leave the former horizontal plane and on the lower side of travelling, when wheel was crossed the slit to next section front end, wheel was subjected to support meeting moment of this front end to get back to the former horizontal plane that travels, and then will produce very big impact force between this front end and the wheel.Reserving gaps is big more, and train speed is high more, and this impact force is just big more.It can travel to wheel track and bring many adverse influences.As impact and understand the very big noise pollution of generation; Impacting the generation vibration can make significantly reduce the application life of each parts, roadbed, rail and the related components of train; Vibration and noise limit wheel-rail train and further improve its travel speed, excessive vibration even can influence the safety traffic of train.
In order to address the above problem, the technology of having used at present has welding to limit expand, contract seamless road rail and magnetic suspended railway.The guiding theory of welding rail is rail to be burn-on one by one realize seamless link completely, rail influenced by temperature and the breathing that produces is elastic deformation by rail self offsets with it, this mode vibration noise problem has solved, but the deficiency that exists is: very high to the welding requirement of strength in order to overcome elastic deformation is extended and the shortening rail is produced along its length tensile stress or compressive stress, the scene will be with special welding and checkout equipment, and the integration engineering cost can improve; Construction seasons is had requirement, and the duration is restricted, and particularly at extremely frigid zones, this restriction is particularly outstanding; Because the welding rail is to adopt stress deformation to limit expanding with heat and contract with cold of rail, this will propose higher construction and installation requirement to roadbed and related components, keeps in repair simultaneously and to change rail very difficult, and particularly the repairing of contingency is just more difficult.This also can make the operation cost of welding rail increase.
Theoretically, adopting magnetic levitation technology is for reducing vibration and noise best choice, and not enough is needs train etc. comprehensively high-tech is supporting, and cost is too high, maintenance difficult.
Some patent application documents have been introduced improvement rail connected mode, make rail connect the seam alteration of form, thereby reach the damping purpose.As patent application ZL01128853.1, " railway track plagiocephaly rendezvous method "; ZL01115229, " inclined impactless expansion joint connecting method for rail "; ZL02118230.2, " method of attachment of rail "; ZL01110729.4, " the vertically bonded structure of steel rail of uninterrupted contact ".More than disclosed patent application, by rail joint is processed, what have makes seam into R-joining; Have seam in two, stagger mutually, form the laterally non-seam that runs through; What have is divided into seam three dummy joints, one of rail one side, and two of opposite sides, two latasutures stagger, and form the laterally non-seam that runs through.These connected mode damping effects are tangible theoretically, mode is also simple and practical, but from the application point analysis, because rail joint is processed, certainly will influence the intensity at rail joint position, if with the fastening of ordinary steel clamping plate, the impact that probably is difficult to bear wheel, therefore these connected modes are required further improvement.
Utility model content the utility model is at the deficiency that exists in the prior art, detailed research the mechanical relationship between wheel and rail during train operation, safety and stability that train should keep have been considered fully when running at high speed, basically do not increasing cost, do not change under the prerequisite of existing installation and maintenance operation rules, design a kind of more rational johning knot member, " steel rail vibration damping with support function connects inner splint ", when solving the wheel track railway operation effectively because vibration and noise problem that the track seam causes, and safe operation problem.
The design of relevant this respect mainly is that launch in the slit of laterally running through that changes on the orbital plane, and what the utility model adopted is the design concept of isosceles triangle seam, continues to use existing track and connects external splint.Joint form was basic identical during it and patent application ZL01110729.4 designed, when using this connection inner splint, the rail junction, the inboard of rail head also will machine away a part, different is the also corresponding part that machines away in flange of rail inboard, in the usual way with rail and this inner splint with bolt after, with the direct plane contact of sleeper upper padding plate, form and the perpendicular stable support structure of train loading direction at the bottom of the inner splint.In the ZL01110729.4 patent application, there is not the braced structures of the flange of rail inboard in the utility model below the inner splint convex-shaped platform.When wheel when the boss, the point that the gravity that supports train is inner clamping plate arc lower edge with the flange of rail has a upper edge, inclined-plane contacts to be realized.Obviously it does not constitute stable support structure.In addition, when clamping plate and rail waist cooperated, lower edge and rail all can be gapped on the clamping plate.When this gap can cause convex platform to be subjected to load, clamping plate can produce downward displacement, thereby the upper surface that makes the convex platform upper surface be lower than rail loses the effect of damping.
A kind of rail damping with support function that the utility model provides connects inner splint, it is characterized in that: discontinuity surface is the L type in the inner splint, and top is inner splint head 1, and the middle part is inner splint waist 2 and connecting bolt hole 3, the bottom is at the bottom of the inner splint 4, and inner splint head, waist and the end are structure as a whole.
The utility model compared with the prior art, the beneficial effect of generation is:
1, the laterally design that connects of rail of rail level isosceles triangle half, the wheel that has solved train effectively produce vibration and noise problem during through the rail connection, also prolong accordingly the application life of train rail and related components simultaneously;
2, the rail after the processing is by after original connected mode bolt, and its upper surface forms the laterally non-seam that runs through of isosceles triangle, and its bottom forms and the similar braced structures of former rail, guarantees the train safe smooth-ride;
This member since waist thickness greater than the thickness of existing rail waist, thereby it has the ability of independent support train gravitational load.
