Abstract
The utility model relates to an flexible fixing system for heel end of rail road frog, which comprises fillers, high strength friction grip bolts, wing rails, long point rails, short point rails and grog heel switch rail, rail bodies of the wing rails, the long point rails, the short point rails and the grog heel switch rail are provided with holes, fillers are respectively arranged between the wing rails and the long point rails, the long point rails and the short point rails, the short point rails and the grog heel switch rail, and flexible pins and high strength friction grip bolts are used to connect accurately. The flexible fixing system for heel end of rail road frog has the advantages that by flexible pins and preparing weld fillers, the frog heel fixing system not only effectively homogenizes longitudinal temperature force from intervals, guarantees position of each element at heel end of the frog to be fixed, and limits excessive extension of long point rails and short point rails, but also ensures stability of geometric pattern of the railroad switch, and guarantees high smoothness of railroad switches.
Description
Technical field
The utility model relates to a kind of railroad frog heel end elastic fixation system, fastening devices, belongs to railroad frog heel end fastening devices and makes the field.
Background technology
1, for resisting the disturbance of interval TEMPERATURE FORCE to the track switch physical dimension, guarantee the geometry morpheme of track switch, solid and reliable track switch heel end of frog fixed system is essential.The heel end of frog of existing track switch fixedly be by high-strength bolt and interval iron will long heart rail, short heart rail, fork be connected with wing rail with tongue, sees accompanying drawing 6.Its weak point: this kind structure is because there is the deviation on making in each component, and the high-strength bolt discontinuity causes that the diseases such as local distortion of the creeping of heart rail, track switch appear in the existing line railway frog because of the effect of thermal stresses.
2,, therefore adopt long wing rail mostly, to transmit the longitudinal force of gapless track because high-speed switch is used for trans-section seamless railway.The effect of heel end of frog structure is the TEMPERATURE FORCE that the opposing circuit passes over, and it is passed to stock rail by lead curve.China popularizes trans-section seamless railway in an all-round way from acclerating road switch, and the rail wing heel end adopts 3～4 block gap iron to be connected with heart rail, and bolt adopts high-strength bolt.According to use experience for many years, wing rail heel end structure is insecure, will cause the heart rail amount of creeping excessive, makes track switch and electric affair equipment produce jam easily, influences the normal use of track switch.At present, the methods that wing rail, heart rail and interval iron are gluedd joint that adopt are strengthened the heel end of frog structure more.Its weak point is: this kind structure is because there is the deviation on making in each component, and the high-strength bolt discontinuity causes that the diseases such as local distortion of the creeping of heart rail, track switch appear in the existing line railway frog because of the effect of thermal stresses.
Germany adopts switch base plate in the heel end of frog bottom, adopts the interval iron of growing up between heart rail and heart rail, wing rail and heart rail, connects with switch base plate by bolt, also is used cross bolts simultaneously and connects; Japan adopts potassium steel block cast frame type wing rail, the fixing fixing mode of group's rail that adopts of heel end of frog, and heel end stability is all relatively good, but the manufacturing process relative complex.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of fixed system of heel end of frog, can bear of the influence of the TEMPERATURE FORCE of track section, keep the geometry morpheme of railway frog to track structure.
Design scheme: in order to realize above-mentioned purpose of design.The utility model is on structure design, adopt the preparation interval iron, high-strength bolt, resilient key will long heart rail, short heart rail, fork carries out precision with tongue with wing rail and is connected, it is major technique feature of the present utility model, and the key that realizes the utility model major technique feature is: 1, resilient key vertically will have a breach, to guarantee when " interference " cooperates assembling, resilient key has certain " compression " amount, can close installation, and satisfy following condition: the one, the resilient key material adopts manganese steel or silico-manganese steel, make it have higher anti-shear ability, shear strength is not less than 698Mpa; The 2nd, resilient key outside diameter d 1 is a bit larger tham the installation aperture on the rail, when mounted, resilient key is squeezed in the installing hole of rail by special tool, guarantees the compactness of installing.The purpose of doing like this is: during TEMPERATURE FORCE that length heart rail is subjected to transmitting between switch area, pass through high-strength bolt, TEMPERATURE FORCE at first is delivered on the resilient key in the length heart rail hole, secondly be delivered to equably on the welding clamping plate by resilient key, be delivered on the resilient key in the wing rail hole by the welding clamping plate again, be delivered on the wing rail equably by the resilient key in the wing rail hole at last.2, preparation interval iron, welding clamping plate in order to obtain the concentricity of clamping plate and rail installing hole, are guaranteed resilient key closely cooperating when mounted when drilling, require the rail of every block welding clamping plate and homonymy to hole simultaneously, the aperture deviation is 0～+ 0.25mm; Welding clamping plate in both sides are by behind resilient key, high-strength bolt and the corresponding rail installation in position, prepare weld interval iron by preparation welding gusset, the technology of joining weldering.The precision-fit of weld interval iron and high-strength bolt is to guarantee the stressed even of each high-strength bolt.Its technical scheme: frog foot end elastic fixation system, it comprises that interval iron, high-strength bolt, wing rail, long heart rail, short heart rail and fork are with tongue, wing rail, long heart rail, short heart rail and fork have the hole with the rail body of tongue, between wing rail and long heart rail, between long heart rail and short heart rail, weak point heart rail is equipped with interval iron respectively between tongue and adopts resilient key respectively and the high-strength bolt precision is connected with pitching to follow.
The utility model is compared with background technology, because track switch longitudinal temperature power is the main cause of track switch geometric form phase perturbation, and the utility model heel end of frog fixed system is by resilient key and preparation weld interval iron, not only effectively homogenising from the longitudinal temperature power in interval, guarantee that each component locations of heel end of frog fixes, limit the excessive flexible of length heart rail, and guaranteed the stable of how much morphemes of track switch, guaranteed the high ride of track switch.
