Description

The novel counter-rail apparatus of elasticity anti-attrition anticreep
Technical field
The utility model relates to a kind of new facility of protecting railway operation safety, strengthened rail structure, is used for the security protection of specific location circuits such as railway curve, tunnel, high embankment and bridge.
Background technology
Extensively use concrete sleeper (containing wide pillow, solid concrete roabed etc.) now on the China railways in a large number, on the circuit in locations such as curve, bridge, tunnel, protect for traffic safety, need to install counter-rail apparatus, the counter-rail apparatus that past uses on wooden sleeper, be on sleeper, guard rail to be followed closely solid inboard at rail with railway spike with guard rail, and the spacing between check rail and the basic rail head inboard is bigger, is difficult to again arrange.This check rail structure is inapplicable to be used on the circuit of concrete sleeper.Also having a kind of is the disclosed old-fashioned counter-rail apparatus of Chinese patent (ZL 97 2 02747.5), and its shortcoming is: the utility function that does not have transverse elasticity and anti-attrition anticreep; Old-fashioned guard rail must adopt special fastener fastening with bolt and sub rail foundation (containing sleeper, solid concrete roabed etc.).Therefore, at the corresponding site of sub rail foundation, must bore many bolts hole; Installing/dismounting is aspect not very all; Old-fashioned counter-rail apparatus is to adopt rail profile moment of inertia I YMay be as bearing wheel to the lateral force of its effect, like this, the supporting capacity of old-fashioned guard rail opposing lateral deformation is very weak, and it is also relatively poor that track structure is strengthened its lateral stability.
Summary of the invention
The purpose of this utility model is to overcome the technical disadvantages that above-mentioned old-fashioned guard rail exists, a kind of novel counter-rail apparatus of elasticity anti-attrition anticreep that connecting relation does not take place with sub rail foundation (containing sleeper, solid concrete roabed etc.) that is applicable to that railroad track is general is provided, on the circuit of the sub rail foundation that makes preparations for sowing (contain concrete sleeper, broad tie, solid concrete roabed with wooden sleeper etc.) and different rail types (contain 75,60,50 and 43kg/m rail), all can install and use, it has multinomial utility function: the abrasion and the rolling contact fatigue that can significantly reduce curve silent partners backbone head side; Can prevent effectively that again the train wheel derailment accident from taking place; Can also strengthen curve track structural-load-carrying capacity (particularly anti-transversal deformability), reduce the orbital maintenance workload; Existing maximum speed limit in the time of can improving train by curve again; And novel check rail (contains generations such as sleeper and solid concrete roabed and directly be connected fastening relation, and installation and maintenance is not easy with sub rail foundation.
The technical solution of the utility model is to realize like this, a kind of novel counter-rail apparatus of elasticity anti-attrition anticreep that is used for concrete sleeper, steel sleeper, broad tie, solid concrete roabed and wooden sleeper circuit, form by guard rail and guard rail bracket etc., its special character is that described guard rail is standard light rail or double end guard rail, and the guard rail waist is provided with the fastening screw keyhole again; Described guard rail bracket is an arm shape, is provided with the bolt hole of installing tache metal plate at an end of support, by bolt, nut, packing ring and buckle metal plate, guard rail bracket is fastened on the flange of rail of stock rail; Middle existing card stock rail flange of rail groove, the bracket bottom other end is provided with for installing and fixing bearing, establishes bolt hole and wear the bolt pin-and-hole on bearing, guard rail is fixed on the bearing of support by bolt; Be provided with the buffer insulation pad between flange of rail groove and the stock rail bottom; In the middle of the hole of guard rail and support, be provided with for the transverse elasticity buffering roll adjustment cushion block of adjusting the guard rail flangeway width; Guard rail is installed the two ends (top and terminal) in location, and being provided with the less guard rail breeze way length in wheel-rail impact angle is 5 meters.Direct fastening relation does not take place with sub rail foundation (containing sleeper etc.) in described guard rail.Described guard rail and the stock rail spacing between the side (being the guard rail flangeway width) K in front are 50~65mm.The horizontal composite rigidity D of described transverse elasticity cushion pad and buffering spacer is 20KN/cm.Described double end guard rail two rail heads, and the upper and lower limit of rail head is all commutative uses as the guard rail working edge.Described guard rail is to adopt rail profile IX square, and the rigidity as the anti-transverse bending of guard rail beam is out of shape can significantly strengthen the integrally-built lateral stability of track, reduces maintenance load.
The utility model advantage compared with prior art is:
1, can prevent effectively that train wheel (or jumping) the rail off-line accident of climbing from taking place;
2, can significantly reduce the inboard face abrasion of curve silent partners rail head; Meanwhile, the side direction abrasion loss of novel guard rail working edge generation is really very little;
3, can effectively alleviate the curve silent partners backbone wheel track rolling contact fatigue (as chapping, peel off, fall piece etc.) of side fillet place generation in front;
4, can renovate curve silent partners master the thigh irregular wear and the hurt of side in front;
5, the integrally-built stability of curve track (particularly lateral stability) can be strengthened, the orbital maintenance workload can be reduced;
6, more smooth and easy in the time of making train pass through curve track; Also can improve the existing maximum speed limit of train by curve;
7, can improve the degree of safety of curve jointless track structure, prevent that curve gapless track expansion rail track accident from taking place;
8, can enlarge the gapless track new technology, the scope of applying on curve track breaks through the practical limit value of its existing set smallest curve radius;
9, guard rail has transverse elasticity distortion function, and the width of flangeway metric of guard rail is easy to adjust.
10, direct fastening relation does not take place with sleeper in guard rail, can install and use on ordinary concrete sleeper, steel sleeper, sleeper, broad tie and ballastless track, and cost is lower, and installation and maintenance are easy;
