The utility model discloses a rail limb that the buckle compressed tightly the stock rail reduces U type rail and props the atress, guarantees simultaneously that the rail props behind the inefficacy, and the stock rail still has the buckle to compress tightly and unlikely to cause the stock rail to turn up and arouse the gauge of a track to exceed standard, influence driving safety nature.
Description
Technical Field
The utility model relates to a railroad switch technical field especially relates to a railroad switch stock rail anti-overturning structure.
Background
The rail brace backing plate is a key part of the climbing type switch point switch, is positioned below the switch point and the stock rail assembly, supports the switch point in the whole length range of the switch point and supports the stock rail so that the stock rail does not turn outwards when a train passes through and is subjected to dynamic load transverse force, and therefore driving safety is guaranteed. Therefore, the rail brace base plate has the effects of providing an action surface for the conversion of the switch blade when the straight strand and the side strand of the turnout are converted, resisting the eversion of the stock rail generated by the transverse dynamic load of the locomotive and ensuring the stability of the stock rail.
The prior anti-overturning integral base plate and a turnout switch (ZL201520991480.2) patent applying the same are characterized in that a supporting plate and a base plate are cast into a whole, the problems that split type rail supports are independently arranged on the base plate and a stock rail, parts are more, gaps easily occur, and the anti-overturning performance is poor are solved, and the integral performance of the turnout is effectively improved. However, because of the inevitable defects of slag inclusion, air holes and the like in the casting process, in the using process, the rail brace of the individual base plate causes cracks due to the inherent defects in casting, and the vibration generated when a train passes at high speed causes the cracks to expand to cause the rail brace to break and fail, thereby causing the problems of eversion of stock rails, expansion of gauge and the like.
SUMMERY OF THE UTILITY MODEL
The utility model provides a railway turnout switch stock rail anti-overturning structure has solved the not enough of prior art, has improved the security and the reliability of goat.
The utility model adopts the technical proposal that: a railway turnout switch stock rail anti-overturning structure comprises an integral base plate, wherein the integral base plate comprises a bottom plate and a U-shaped rail support positioned on one side above the bottom plate, a stock rail is arranged in a rail groove of the bottom plate, and a rail web of the stock rail is fixedly connected with the U-shaped rail support through a horizontal bolt pair; the bottom plate is provided with a mounting boss which is positioned in the center of the U-shaped rail support; the installation boss is fixed with a buckle plate, and the inner side of the buckle plate is buckled and pressed on the rail limbs of the stock rail.
The center of the mounting boss is sequentially provided with a through hole I and an arc mounting groove from top to bottom; the lower end face of the buckle plate is provided with a positioning boss, the buckle plate is provided with a through hole II on the outer side of the positioning boss, and the lower end face on the inner side of the positioning boss is a buckling inclined face; the buckle plate is clamped in the arc-shaped mounting groove through a T-shaped head of the T-shaped bolt, a screw rod of the T-shaped bolt penetrates through the through hole I, the through hole II and the sleeve nut from bottom to top and is fixed on the mounting boss, the positioning boss is embedded between the rail limb and the mounting boss, and the buckling inclined plane is tightly pressed on the rail limb.
Compared with the prior art, the utility model discloses beneficial effect who has:
1. the utility model adopts the buckle plate to compress the rail limbs of the stock rail, reduces the stress of the U-shaped rail brace, and simultaneously ensures that the stock rail still has the buckle plate to compress without causing the eversion of the stock rail to cause the gauge exceeding the standard and influencing the driving safety after the rail brace is out of service;
2. the pinch plate is simple and compact in structure and easy to manufacture, and meanwhile, after the pinch plate is installed, the pinch plate is prevented from rotating to enable the compression surface to be separated from the rail limb surface through the positioning boss on the lower end surface of the pinch plate, so that the safety and the reliability of the switch are improved.
