Abstract
The invention belongs to the rail joint of rail track and associated railways splint.(being called for short E type clamping plate rail joint), be characterised in that: eliminating has seam rail joint disease and the huge and harmful temperature system stress of gapless track.The characteristics of this rail joint, railways splint are: simple and reasonable, make track structure safer, reliable, stable, elimination has the shock loading (alleviating the construction weight of vehicle in the time of can improving the carrying capacity of existing vehicle thus or make vehicle) of seam rail, train does not produce the sound during by this structure makes train travel steady, reduce the railroad traction loss, improve the application life that road speed prolongs rail and rolling stock.
Description
The invention belongs to the rail joint and the railways splint (being called for short E clevis slab rail joint) of rail track.
Carry according to (" track " 79 years railway publishing houses publish) book 85-86 page or leaf: weight is hindered rail joint disease and is accounted for 50% of sum, accounts for the 35-50% of maintenance work total amount; 43 kilograms of rails account for 70% when wheel moves to joint, enter rail and are higher than other end rail level, form step and knuckle, produce collision, and additional power increases by 28%.Impact force can reach tens tons.
For overcoming the above defective of rail joint, produced gapless track, but gapless track has limited freely stretching of rail, as temperature difference 1C, 50 kilograms of rail will bear 1645 kilograms of pressures, and temperature difference 40C will reach 132 tons, also must invest in fixed area, breathing zone, buffer area, lay special stress on uses strong intermediate fastening " track " 38-40 page or leaf.
Design philosophy of the present invention is: eliminating has seam rail joint disease and huge thermal stresses while of seamless rail, reaches the useful result of use of seamless rail.
The method that solves is at the problem that seam, the technical existence of seamless rail are arranged, and designs a kind of E clevis slab rail joint of uniqueness simple in structure, easy to process, embodies the design philosophy that the present invention proposes.This E clevis slab rail joint is connected with bolt, nut, packing ring by lapping rail joint, E clevis plate, employing interference fits, the FG end is welded on the 12.5M that joins with the solder technology of gapless track, and the termination of 25M non-bolt hole rail forms.The material that rail joint uses should be identical with the steel rail material of welding mutually or the different carbon equivalents of both materials are suitable, and quenching technical is according to the employed quenching technical of original steel rail ends.
Clamping plate employing 40C γ or the more comprehensive low-alloy structural steel of other comprehensive mechanical performance are with the γ B151-63B6 and the rolling manufacturing of B7 killed steel (also can adopt B6 and B7 killed steel) of alternate country standard dual head formula clamping plate defined.
Marked improvement of the present invention is: the lapping rail joint structure of this uniqueness, when wheel runs to this end of joint, the rail joint two ends remain in one plane, eliminated original seam rail joint, when moving, wheel forms step and knuckle, unsettled and collision phenomenon, rail can freely stretch when reaching the useful effective utilization of gapless track, there is not the harmful thermal stresses of gapless track, the main feature that is this E clevis slab rail joint is: eliminate the shock loading of train, increase the actual load amount of existing vehicle, reduce the railroad traction loss, improve road speed, prolong the application life of rail and rolling stock.
Description of drawings: E clevis slab rail joint design schematic diagram.
As scheming: (1) lapping rail joint, (2) bolt, (3) nut, (4) packing ring, (5) trapezoidal screw, (folding
Clamping plate are used) (6) E clevis plate.
Claims (3)
1, the E clevis slab rail joint invention that requires to grant patent belongs to the rail joint and the railways splint of rail track, it is characterized in that: eliminate the thermal stresses that seam rail joint disease and gapless track are arranged, rail joint and clamping plate adopt interference fits, and F, G end is welded on the steel rail ends that joins and forms.
2, come slab rail joint by the described E shape of claim 1, be characterised in that: rail joint adopts overlapping, can by 50 kilograms/meter of E clevis slab rail joint principle designs, 60 kilograms/meter, 45 kilograms/meter, 38 kilograms/meter ... the any type rail.
3, according to claim 1 or 2 described E clevis slab rail joints, it is characterized in that: the material that rail joint uses is made with the material rail system that steel rail material is identical or the different carbon equivalents of material are suitable of welding mutually, and the clamping plate material adopts 40C γ or other low B6 and rolling manufacturing of B7 killed steel that contains golden structural iron or γ B151-63 regulation.
