Abstract
A kind of track line switch area tongue fastener system, its main feature is that, slide plate is fixed on track plate, and cross section is T-shaped structure, and the bottom end of fastener body is provided with T shape cavity, and the T shape cavity of fastener body is nested on slide plate T shape profile；Tongue rail bottom passes through time anchor bolt and is connected with fastener body；Hydraulic press is installed inside fastener body, support block, withholds spring, spring is withheld and is fixed on support block by pin shaft, the one end for withholding spring is located above hydraulic press, and the other end is in tongue rail bottom upper surface.Track line switch area tongue fastener system of the invention, by the lifting for controlling hydraulic press piston rod, make to withhold spring around support block make it is suitable, rotate counterclockwise, according to lever principle, it can apply or remove buckle press on trouble area's tongue, it solves the problems, such as to be coupled between tongue and slide plate without fastener, reduces the strenuous vibration that train high speed crosses tongue when branching off, substantially increase train travel stationarity and degree of passenger comfort.
Description
Technical field
The present invention relates to railway traffic equipment, especially a kind of track line switch area tongue fastener system.
Background technique
Track switch is the line connection equipment that rolling stock was transferred to or crossed another station track from a station track, is the weight of railroad track
Component part and the system integration are wanted, is the critical infrastructures for influencing driving stationarity and safety.Currently, China railways and city
Applying in city's rail traffic at most is common single turnout, it is by three railway switch, coupling part, railway frog and guard rail unit groups
At.Tongue is then the important component in railway switch, can be divided into linear type and shaped form in the plane, can by pulling for tongue
Train is introduced into main track or side line direction running.
However, point tongue, after slicing, section has obtained very big weakening, moving part is supported on slide plate,
It is coupled with slide plate without fastener.When train high speed is passed through, there is very big transverse direction and longitudinal direction impact force to track switch, and thus cause
The strenuous vibration of tongue brings security risk to the operation of vehicle, deteriorates driving stationarity and degree of passenger comfort, make line facility
Quality decline, increases maintenance costs.In order to limit the transverse direction and vertical displacement of tongue when train crosses trouble, the vibration for reducing tongue is rung
It answers, the point of switch is on the one hand set as point-hiding structure, to reduce wheel to the impact vibration of the point of switch；On the other hand it utilizes
The locking device of railway switch limits the horizontal vertical displacement of tongue, but the two to reduce tongue vibratory response effect not
Obviously.
Summary of the invention
It is an object of the invention to provide a kind of vibratory responses that can reduce tongue when train high speed crosses trouble, and it is flat to improve driving
The track line switch area tongue fastener system of stability and degree of passenger comfort.
Track line switch area tongue fastener system of the invention, including slide plate, fastener body, which is characterized in that sliding
Bed board is fixed on track plate, and cross section is T-shaped structure, and the bottom end of fastener body is provided with T shape cavity, the T shape of fastener body
Cavity is nested on slide plate T shape profile, the two Matching installation；Tongue rail bottom passes through time anchor bolt and is connected with fastener body,
Fastener body can with moving left and right for tongue synchronizing moving；Hydraulic press is installed inside fastener body, support block, withholds bullet
Item is withheld spring and is fixed on support block by pin shaft, and can rotate around pin shaft, and the one end for withholding spring is located on hydraulic press
Side, the other end are in tongue rail bottom upper surface, and hydraulic press is connect with track switch semaphore, by track switch semaphore control hydraulic press
Working condition.
Track line switch area tongue fastener system working principle of the invention is, when train will cross trouble, when needing point
When rail and stock rail are closely connected, switch machine starts to draw tongue to the movement of stock rail direction, and at the same time, tongue drives fastener master
Body slides in the same direction on slide plate, and after tongue and stock rail are completely closely connected, trouble area's semaphore will control hydraulic press and start
Work is lifted its piston rod height, while drive is withheld spring and rotated clockwise around support block, until withholding the another of spring
One end and tongue rail bottom upper surface are in close contact, in this way, just be applied with a very big buckle press on tongue rail bottom surface；
When needing tongue to separate with stock rail, trouble area's semaphore will control hydraulic press start-up operation, reduce its piston rod height, together
When drive and withhold spring and rotated counterclockwise around support block, up to the other end and tongue rail bottom upper surface of withholding spring are complete
Separation after removing to tongue buckle press, turns in this way, which the buckle press for being applied to tongue rail bottom upper surface is just revoked
Rut machinery starts to draw tongue to the movement of stock rail opposite direction, and at the same time, tongue pushes fastener body in the same direction on slide plate
Sliding, until tongue is kept completely separate with stock rail.Trouble area's tongue is withheld in this way, can realize, to reduce train high speed
The vibratory response of tongue when crossing trouble.
Track line switch area tongue fastener system of the invention makes to withhold by controlling the lifting of hydraulic press piston rod
Spring around support block make it is suitable, rotate counterclockwise, according to lever principle, can apply or remove buckle press on trouble area's tongue,
It solves the problems, such as to be coupled between tongue and slide plate without fastener, reduces the strenuous vibration that train high speed crosses tongue when branching off, greatly
Train travel stationarity and degree of passenger comfort are improved greatly.

Specific embodiment
A kind of track line switch area tongue fastener system, including slide plate 8, fastener body 3, which is characterized in that slider bed
Plate 8 is fixed on track plate 9, and cross section is T-shaped structure, and the bottom end of fastener body 3 is provided with T shape cavity, the T of fastener body 3
Shape cavity is nested on slide plate T shape profile, the two Matching installation；7 rail bottom of tongue passes through time anchor bolt 12 and fastener body 3
It is connected, fastener body 3 can moving left and right and synchronizing moving with tongue 7；Hydraulic press 4, supporting station are installed inside fastener body 3
Seat 5 withholds spring 6, withholds spring 6 and is fixed on support block 5 by pin shaft, and can rotate around pin shaft, withholds the one of spring 6
End is located at 4 top of hydraulic press, and the other end is in 7 rail bottom upper surface of tongue, and hydraulic press 4 is connect with track switch semaphore, by track switch
The working condition of semaphore control hydraulic press.Track plate 9 is fixed on sleeper 1 with Bower Anchor fixing bolt 2.
