Abstract
A combined-type fastener for track vibration reduction comprises a flexible track lower cushion (2), an inner iron plate (3), a flexible plate lower cushion (4), a rubber and plastic baffle plate (5),an outer iron plate (6), a raising plate (7), a bolt (8), an iron gasket (9) and a nylon gasket (10). The flexible track lower cushion in identical length and width with the bottom of a steel track is placed below the steel track (1); the flexible track lower cushion is positioned in the clamping groove in the inner iron plate; the flexible plate lower cushion with identical surface area of the inner iron plate is arranged below the inner iron plate; the right-angled rubber and plastic baffle plate is arranged around the inner iron plate and the flexible plate lower cushion; the outer iron plate is pressed on the horizontal plane of the right-angled rubber and plastic baffle plate; the raising plate is arranged below the outer iron plate; threaded holes are formed at the opposite angles of the outer iron plate; the iron gasket is pressed on the threaded holes and simultaneously pressed on the outer iron plate and the inner iron plate; and the outer iron plate is fixed on a sleeper (11) through the bolt after the nylon gasket is additionally arranged. The utility model has the advantages of good vibration reduction effect, strong suitability, and convenient maintenance and replacement.
Description
Technical field
The utility model belongs to track accessory technical field, especially a kind of track vibration-reducing combined type fastener.
Background technology
Fastener is the important component part of track structure, and it is combined as section of track structure with rail and sleeper, bears train load, and opposing is in length and breadth to active force.It is again the supplier of track elasticity and adjustment capability simultaneously, plays certain vibration and noise reducing effect.
In the present track circuit, general vibration damping highway section accounts for about 70% of whole highway section, needs to use a large amount of Damping fastenings.But the structure design of existing such fastener has limited its damping property greatly, mainly show following some:
1. fastener dismounting difficulty is keeped in repair, is changed inconvenience, as " clone's egg " type Damping fastening;
2. fastener is connected by bolt with sleeper, and Bolt Tightening Force is big, and screwing force all is passed to the plate underlay, causes plate underlay precompression excessive, and the elasticity of plate underlay is shunk greatly;
3. fastener system is heightened ability, and is poor for applicability.
Summary of the invention
In order to address the above problem, the utility model has designed a kind of track vibration-reducing combined type fastener, this combined type fastener good damping result, and compliance is strong, and maintenance, replacing are conveniently.
For achieving the above object, the utility model adopts following technical scheme:
Described a kind of track vibration-reducing combined type fastener is by the resilient rail underlay, interior iron chair, the elastic plate underlay, the rubber and plastic dividing plate, outer iron chair, height adjusting cushion plate, bolt, iron washer and nylon washer constitute, wherein the resilient rail underlay places rail below and isometric wide with rail foot surface, the resilient rail underlay is arranged in the draw-in groove of interior iron chair, below interior iron chair, be provided with the elastic plate underlay identical with interior iron chair surface area, around interior iron chair and elastic plate underlay, be provided with right angle rubber and plastic dividing plate, iron chair outside on the horizontal plane of right angle rubber and plastic dividing plate, being pressed with, outer iron chair below configuration height adjusting cushion plate, outer iron chair diagonal angle configuration screwed hole, iron washer is pressed on the screwed hole can push down outer iron chair and interior iron chair simultaneously, by bolt outer iron chair is fixed on the sleeper after adding nylon washer then.
Described a kind of track vibration-reducing combined type fastener, its outer iron chair horizontal plane are lower than interior iron chair horizontal plane, and the height in right angle rubber and plastic dividing plate is clipped between iron chair and the outer iron chair is to be lower than interior iron chair, to be higher than outer iron chair.
Because adopt aforesaid technical scheme, the utility model produces following good effect:
1, greatly reduces the precompressed of elastic plate underlay, even can be reduced to zero precompressed, can give full play to the elasticity of plate underlay, improve the effectiveness in vibration suppression of combined type fastener.
2, can be according to the height of circuit needs configuration height adjusting cushion plate.
3, each parts of combined type fastener are separate type, its maintenance, change convenient, quick.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
Fig. 2 is that interior iron chair and outer iron chair cooperate top perspective view.
Among the above-mentioned figure: the 1-rail; 2-resilient rail underlay; Iron chair in the 3-; 4-elastic plate underlay; 5-rubber and plastic dividing plate; The outer iron chair of 6-; The 7-height adjusting cushion plate; The 8-bolt; The 9-iron washer; The 10-nylon washer; The 11-sleeper.
The specific embodiment
In conjunction with Fig. 1, a kind of track vibration-reducing combined type fastener of the present utility model is by resilient rail underlay 2, interior iron chair 3, elastic plate underlay 4, rubber and plastic dividing plate 5, outer iron chair 6, height adjusting cushion plate 7, bolt 8, iron washer 9 and nylon washer 10 constitute, wherein resilient rail underlay 2 places rail 1 below and isometric wide with rail foot surface, resilient rail underlay 2 is arranged in the draw-in groove of interior iron chair 3, below interior iron chair 3, be provided with the elastic plate underlay 4 identical with interior iron chair surface area, around interior iron chair 3 and elastic plate underlay 4, be provided with right angle rubber and plastic dividing plate 5, iron chair 6 outside on the horizontal plane of right angle rubber and plastic dividing plate 5, being pressed with, outer iron chair 6 belows configuration height adjusting cushion plate 7, outer iron chair 6 diagonal angles configuration screwed hole, iron washer 9 is pressed on the screwed hole can push down outer iron chair 6 and interior iron chair 3 simultaneously, adds that then nylon washer 10 backs are fixed on outer iron chair 6 on the sleeper 11 by bolt 8.It should be noted that outer iron chair 6 horizontal planes are lower than between 0～2mm of interior iron chair 3 horizontal planes, the height in right angle rubber and plastic dividing plate 5 is clipped between iron chair 3 and the outer iron chair 6 is iron chair 3 in being lower than, is higher than outer iron chair 6.
During use, earlier height adjusting cushion plate 7 is arranged on the sleeper 11, the quantity of height adjusting cushion plate 7 can be selected for use according to the actual installation situation of circuit, right angle rubber and plastic dividing plate 5 is set on height adjusting cushion plate 7 then, in the centre of right angle rubber and plastic dividing plate 5 elastic plate underlay 4 and interior iron chair 3 are set respectively, on the interior iron chair 3 resilient rail underlay 2 is set, right angle rubber and plastic dividing plate is provided with outer iron chair 6 on the 5 horizontal plane outers, outer iron chair 6 is tightened, is fixed on the sleeper 11 after being inserted in iron washer 9 and nylon washer 10 on the bolt 8 successively.At last, interior iron chair 3 and resilient rail underlay 2 are by track gauge block and spring and rail 1 fixing getting final product.
After the combined type fastener was installed, elastic plate underlay 4 suffered precompressions approached zero, can give full play to the elasticity of elastic plate underlay 4, played the favorable damping effect.Height adjusting cushion plate 7 can be selected for use according to actual track, convenient construction.This combined type fastener adopts detachable structure, and it is convenient to safeguard, change.
