Description
Technical field
The utility model relates to railway rail clip, specially a kind of mating small-resistant fastener device of railway steel bridge composite sleeper
System.
Background technique
It is that rail is fixed on sleeper as connection rail and the railway rail clip of intermediate connection assembly of sleeper its effect,
It keeps gauge and prevents rail vertically and horizontally moving relative to sleeper.On the track of sleeper, the elasticity of concrete sleeper is poor.
Railway steel bridge composite sleeper effectively keeps the requirement of the reliable connection between rail and sleeper to intensity, durability, elasticity
It is very high, just from the point of view of current existing fastener service condition, maintain to need in the maintenance state of railway steel bridge composite sleeper upper fastener
It frequently to maintain and adjust very, it should say that existing fastener is not suitable with the application of railway steel bridge composite sleeper.
Summary of the invention
The utility model against the above technical problems, provides a kind of mating small-resistant fastener dress of railway steel bridge composite sleeper
Set system, it is therefore intended that in holding gauge and rail is prevented to provide enough bullets on the basis of vertically and horizontally moving relative to sleeper
Property, have enough intensity, durability, it is flexible, effectively keep reliable connection between rail and sleeper, part is few, installation
Simply, easy to disassemble.
The specific technical solution of the utility model is as follows:
The mating small-resistant fastener apparatus system of railway steel bridge composite sleeper, by T-type dormant bolt, nut, spring washer,
Buckle/connector buckle, rubber pad placed under-neath rail, iron chair, plate lower gasket, screw spike composition, it is characterised in that: iron chair is arranged in plate
On lower gasket, rubber pad placed under-neath rail is arranged in iron chair trade mark, and buckle/connector buckle is pressed in rail outer rim and is arranged on iron chair, bullet
The setting of spring washer is arranged on buckle/connector buckle, and T-type dormant bolt, nut run through spring washer, buckle/connector buckle chain
Clasp device is whole, passes through screw spike fixed iron chair, plate lower gasket.
Iron chair compared to the mating fastener device of existing railroad sleeper is arranged on plate lower gasket/height adjusting cushion plate paper,
Baffle lower cushion block, apron block are arranged on iron chair, the upper surface of baffle lower cushion block apron block setting gauge apron, on gauge apron
Resistance spring is set, and plain washer is arranged on resistance spring, is fixed on iron chair by T-type dormant bolt and nut device
On, pass through the structure of the fixed iron chair plate lower gasket/height adjusting cushion plate of screw spike.The utility model is keeping gauge and is preventing steel
Rail is durability, flexible, effective relative to providing enough elasticity on the basis of vertically and horizontally the moving of sleeper, have enough intensity
Ground keeps the reliable connection between rail and sleeper.Part is few, and installation is simple, easy to disassemble.
Detailed description of the invention
Fig. 1 is the utility model section structural schematic diagram.
Fig. 2 is the utility model overlooking structure diagram.
Wherein, 1 --- T-type dormant bolt, 2 --- nut, 3 --- spring washer, 4 --- buckle/connector buckle,
5 --- --- iron chair, 7 --- plate lower gasket, 8 --- screw spikes of rubber pad placed under-neath rail, 6.
Specific embodiment
The mating small-resistant fastener apparatus system of railway steel bridge composite sleeper, by T-type dormant bolt, nut, spring washer,
Buckle/connector buckle, rubber pad placed under-neath rail, iron chair, plate lower gasket, screw spike composition, it is characterised in that: iron chair is arranged in plate
On lower gasket, rubber pad placed under-neath rail is arranged in iron chair trade mark, and buckle/connector buckle is pressed in rail outer rim and is arranged on iron chair, bullet
The setting of spring washer is arranged on buckle/connector buckle, and T-type dormant bolt, nut run through spring washer, buckle/connector buckle chain
Clasp device is whole, passes through screw spike fixed iron chair, plate lower gasket.This system device is keeping gauge and is preventing rail
It is durability, flexible, effectively relative to providing enough elasticity on the basis of vertically and horizontally the moving of sleeper, have enough intensity
Keep the reliable connection between rail and sleeper.Part is few, and installation is simple, easy to disassemble.
