Description
Technical field
The utility model relates to railway equipment technical field more particularly to steel rail heightening technologies.
Background technique
Elastic bar fastener is one of rail fastening, and it is the weight of track structure that effect, which is that rail is fixed on sleeper,
Component part is wanted, possesses fixed location of rail, keep gauge and rail is prevented vertically and horizontally to be displaced relative to sleeper, fastener can
It is effective that rail is kept to be coupled with sleeper, and its bumper and absorbing shock function can be given full play under the action of power, simple structure, just
In installation and disassembly.
With the development and application of concrete crosstie, a variety of elastic bar fastener patterns are developed, such as I type fastener of spring, spring strip II
There are various high speeds again in type fastener, elastic fastener, I type tightening means for height-adjusting of spring etc., fast-developing with high-speed railway
Railway fastener, but there is still a need for use I type fastener of spring, spring strip II type fastener, elastic fastener, spring for existing line maintenance
I type tightening means for height-adjusting.
I type fastener of spring, spring strip II type fastener have the ability of adjustment gauge, but do not have the ability of height-regulating, are repairing
In the process, the adjustment of height is needed using operation is repaired by the way of smashing, especially in northern China cold district, when
Roadbed bed soil on rail track is frost heave soil, and when drainage condition is bad, the water in soil is redistributed in freezing process, ice
Block is unevenly assembled, and bedding is caused unevenly to swell, and is rebuild according to the mode smash is acted, the spring is necessarily caused to melt the more of season
Secondary track lowering operation repeatedly both influences driving in this way and also increases cost, while damaging to the stability of railway roadbed, influences driving
Stationarity.
When keeping rail top mark high different solid concrete roabed variation, original rail fastening is unable to normal use, needs replacing
Tightening means for height-adjusting adjusts the height of rail, guarantees the ride comfort of rail, traditional height-regulating mode is substantially to be turned up using spring, such as
" the I type tightening means for height-adjusting of spring assembling configuration " of standard TB 1911.1-87, Spring bar height-regulating fastener be only limitted to using height-regulating amount not
Greater than in 20mm height, since the height that freeze injury route or other environmental factors cause each fastener to need to adjust is different, need
The fastener size and disunity of replacement, therefore bring a lot of trouble to order, installation and replacement, while also increasing cost.
Utility model content
In order to solve the problems, such as that rail bedding because unevenly swelling caused by freeze injury or other reasons, provides one kind and do not need
The freeze injury tightening means for height-adjusting that the height-regulating buckle of replacement different size can adjust different height and be easily installed.
The utility model technical solution used for the above purpose is: a kind of steel rail heightening fastener is installed on steel
11 two sides of rail, including seat 1 and pressing plate 2 is turned up, two pressing plates 2 are connected by axis 12, and seat 1 is turned up and is located at two pressing plates, 2 outside, adjusts
The circular arc on 1 top of dais is coupled with axis 12, and 1 tail end circular arc of seat and the closely connected cooperation of apron block 7 is turned up, and pressing plate 2 is equipped with and is used for
The crowning of different height, crowning and 11 rail bottom contact of incline plane of rail are set；Seat 1 is turned up and is installed on 10 top of sleeper, is turned up
1 bottom of seat is equipped with hole, and 1 top of seat is turned up and successively installs spring 6 and plain washer 5, and seat 1, spring 6 and plain washer 5 is turned up and passes through spiral shell
It revolves railway spike 3 and nut 4 is fixed, 6 one end of spring is coupled with 1 tail end arc groove of seat is turned up, and rubber mat plate 8 is located at rail 11
Height adjusting cushion plate 9 is installed in lower part between 8 lower part of rubber mat plate and sleeper 10.
Barricade is no more than 3mm perpendicular to sleeper 10, tilt angle before the height-regulating seat 1.
The steel rail heightening fastener of the utility model by setting pressing plate and is turned up seat, realizes appointing for rail different height
Meaning is adjusted, and does not need the tightening means for height-adjusting that replacement meets size, quick and easy for installation, at low cost.

Specific embodiment
The steel rail heightening fastener structures of the utility model as shown in figs. 1-7, are installed on 11 two sides of rail, freeze injury tightening means for height-adjusting
It is fixed with spring, apron block, screw spike, plain washer, nut, rubber mat plate, height adjusting cushion plate assembling.Including seat 1 and pressure is turned up
Plate 2, two pressing plates 2 are connected by axis 12, and seat 1 is turned up and is located at two pressing plates, 2 outside, the circular arc that 1 top of seat is turned up is matched with axis 12
Installation is closed, 1 tail end circular arc of seat and the closely connected cooperation of apron block 7 is turned up, pressing plate 2 is equipped with the crowning for different height to be arranged, convex
The face of rising and 11 rail bottom contact of incline plane of rail；Seat 1 is turned up and is installed on 10 top of sleeper, 1 bottom of seat is turned up and is equipped with hole, is turned up on seat 1
Spring 6 and plain washer 5 are successively installed by portion, and seat 1, spring 6 and plain washer 5 is turned up and is fixed by screw spike 3 and nut 4, spring 6
One end is coupled with 1 tail end arc groove of seat is turned up, and rubber mat plate 8 is located at 11 lower part of rail, 8 lower part of rubber mat plate and sleeper
Height adjusting cushion plate 9 is installed between 10.
When needing to adjust 11 height of rail, first nut 4, plain washer 5, spring 6 are removed, pressing plate 2 is rotated to corresponding
Highly, rail 11 is raised, the height adjusting cushion plate 9 of respective thickness is padded between rail 11 and concrete sleeper, spring 6 is successively installed, is put down
Washer 5 finally tightens nut 4 to standard torque.Notice that the square hole observed and seat 1 is turned up in adjustment as far as possible should be in spiral channel when installation
The center of nail 1, is turned up 1 tail end circular arc of seat and nylon baffle seat 7 needs closely connected cooperation, and barricade should be perpendicular to coagulation before seat 1 is turned up
Soil pillow, may not exceed 3mm if any inclination.It, can if gradient is more than that 3mm illustrates that rail adjustment height is not inconsistent with pressing plate upturned position
The position that pressing plate is overturn by adjusting the height or continue of liner guarantees to be turned up the vertical of barricade before seat, observes pressing plate and rail
Whether rail bottom ramp contacts tight firm, and there can be no point contact phenomenons.
It, can be according to reality when such as causing the assembly of freeze injury tightening means for height-adjusting unreasonable because of sleeper 10, rail 11 and fastener manufacture deviation
Border situation is adjusted, but must assure that its safety.
