Background technology
ω elastic bar fastener is because of the adjustable characteristic of its buckle press, it is adaptable to the section of different demands and facilitate the adjustment of operating line, has the most become the broad form of domestic and international rail fastener；In the installation of ω elastic bar fastener and when safeguarding, be required to " three point contact ", i.e. fastener reach set moment of torsion install put in place time, two elastic arms of ω spring and middle ring the most simultaneously with rail foot or track gauge block upper surface；Though above-mentioned requirements reduces to a certain extent and installs the difficulty safeguarded; but do not take into full account the overload protection problem of rail; i.e. when suffered by rail, cross force is excessive; the windup-degree of rail the most just has the danger toppled greatly; having buried huge hidden danger for traffic safety, the personal safety and safety of property of passenger in serious threat.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is to propose ω spring and the elastic bar fastener system that a kind of anti-rail topples.
This utility model adopts the following technical scheme that for completing above-mentioned purpose
The ω elastic bar fastener system that a kind of anti-rail topples, described elastic bar fastener system includes ω spring, fastening bolt and spring seat；Described spring seat is be positioned at rail both sides two；Described ω spring has middle ring, and described middle ring is arc；Both sides bottom described middle ring are respectively arranged with high-elastic elastic arm；Two described described high-elastic elastic arms are connected to the arc opening end of middle ring respectively by bending section；It is characterized in that: the most at grade, and the bottom surface of described middle ring is higher than the bottom surface of described high-elastic elastic arm in the bottom surface of the bottom surface of described middle ring and described high-elastic elastic arm；Distance d between described middle ring bottom surface and high-elastic elastic arm bottom surface is 10～15mm；Described ω spring is positioned on described spring seat；Two high-elastic elastic arms of described ω spring are directly withheld on the foot of rail, or withhold on the foot of rail by track gauge block, and the distance between the bottom surface of described middle ring and the bottom surface i.e. upper surface of track gauge block of high-elastic elastic arm or rail foot is 10～15mm；Described ω spring is connected as one with described spring seat by fastening bolt, when fastening bolt reach set moment of torsion install put in place time, ω spring reaches setting value to the buckle press of rail, and the distance between bottom surface and the bottom surface of high-elastic elastic arm of described middle ring is maintained at 1～5mm；When suffered by rail, cross force is excessive, rail can be torqued into certain angle, the now middle ring of ω spring and the foot of rail or track gauge block upper surface, and the rigidity of ω spring can be big suddenly, is formed " secondary rigidity ", stops rail to reverse further.
Described fastening bolt is T-bolt, described spring seat has the head with T-bolt and kisses the draw-in groove joined；The upper end of described fastening bolt passes spring seat, the described middle ring of ω spring, and is fastened by nut.
On described spring seat, there is the bolt hole coordinated with fastening bolt；The lower end of described fastening bolt connects as one through the described middle ring of ω spring with described spring seat.
The ω elastic bar fastener system that a kind of anti-rail that the utility model proposes topples, use technique scheme, when the moment of torsion of fastening bolt reach predetermined value install put in place time, two high-elastic elastic arms of ω spring are withheld tightly at rail foot or track gauge block upper surface, but wherein ring still has a certain distance with rail foot or track gauge block upper surface；The advantage of this utility model is; when suffered by rail, cross force is excessive; rail can be torqued into certain angle; the now middle ring of ω spring and rail foot or track gauge block upper surface; the rigidity of ω spring can increase suddenly, stops rail further to reverse, thus the major accident avoiding rail to topple occurs; thering is provided overload protection for train safe, the personal safety and safety of property for passenger escorts.
