Description
Technical field
The invention belongs to technical field of rail traffic, be specifically related to the ω elastic bar fastener system that a kind of anti-rail topples.
Background technology
ω elastic bar fastener, because of the adjustable characteristic of its buckle press, is applicable to the section of different demand and facilitates the adjustment of operating line, having become the broad form of domestic and international rail fastener at present; In the installation of ω elastic bar fastener and when safeguarding, all require " three point contact ", namely fastener is when reaching set moment of torsion and being in place, and two elastic arms of ω spring contact with rail foot or track gauge block upper surface just with middle ring simultaneously; Though above-mentioned requirements reduces the difficulty of installation and maintenance to a certain extent; but do not take into full account the overload protection problem of rail; namely when suffered by rail, lateral force is excessive; the windup-degree of rail just has the danger of toppling greatly to a certain extent; for traffic safety has buried huge hidden danger, the personal safety and safety of property of passenger in serious threat.
Summary of the invention
For solving the problems of the technologies described above, the object of the invention is to propose the ω spring that topples of a kind of anti-rail and elastic bar fastener system.
The present invention adopts following technical scheme for completing above-mentioned purpose:
The ω elastic bar fastener system that anti-rail topples, described elastic bar fastener system includes ω spring, fastening bolt and spring seat; Described spring seat is for being positioned at two of rail both sides; 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; Described high-elastic elastic arm described in two is connected to the arc opening end of middle ring respectively by bending section; It is characterized in that: not at grade, and the bottom surface of described middle ring is higher than the bottom surface of described high-elastic elastic arm for the bottom surface of described middle ring and the bottom surface of 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 of high-elastic elastic arm and the upper surface of track gauge block or rail foot is 10 ~ 15mm; Described ω spring is connected as one by fastening bolt and described spring seat, when fastening bolt reach set moment of torsion be in place time, the buckle press of ω spring to rail reaches setting value, and the distance between the bottom surface of described middle ring and the bottom surface of high-elastic elastic arm remains on 1 ~ 5mm; When suffered by rail, lateral force is excessive, rail can be torqued into certain angle, and now the middle ring of ω spring contacts with the foot of rail or track gauge block upper surface, and the rigidity of ω spring can be large suddenly, formed " secondary rigidity ", stop rail to reverse further.
Described fastening bolt is T-shaped bolt, described spring seat has and kisses the draw-in groove of joining with the head of T-shaped bolt; The described middle ring of spring seat, ω spring is passed in the upper end of described fastening bolt, and by fastening nuts.
Described spring seat has 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 and described spring seat.
The ω elastic bar fastener system that a kind of anti-rail that the present invention proposes topples, adopt technique scheme, when the moment of torsion of fastening bolt reach predetermined value be 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 and rail foot or track gauge block upper surface still have certain distance; The advantage of this invention is; when suffered by rail, lateral force is excessive; rail can be torqued into certain angle; now the middle ring of ω spring contacts with rail foot or track gauge block upper surface; the rigidity of ω spring can increase suddenly, stop rail further to reverse, thus the major accident avoiding rail to topple occurs; for train safe provides overload protection, for the personal safety and safety of property of passenger escorts.
