Description
Technical field
The utility model is related to a kind of fastener systems of achievable gapless track temperature stress automatic relief.
Background technology
Gapless track greatly reduces the quantity of rail joint, increases the ride comfort and driving stationarity of track structure,
Significantly reduce the percussion to rail when rolling stock is run.Operating practice proves, the maintenance in gapless track location
Expense reduces 35%~75% than common line；Therefore, gapless track is because its driving is steady, maintenance cost is low, equipment makes
It the advantages that with long lifespan and high passenger's comfort, is answered extensively in the fast development of China express railway and heavy haul railway
With.When rail temperature amplitude of variation is larger, huge temperature stress is will produce inside rail, if do not carried out destressing in due course,
Under the influence of the extraneous factors such as periodical train load, it will cause gapless track occur expansion rail track, brittle fractures of rail phenomena such as, sternly
Ghost image rings travel safety.Therefore, it is very necessary to carry out destressing to gapless track.
Currently, gapless track destressing is divided into automatic relief formula and periodically diffuses two kinds of formula.What automatic relief formula used
Method is that expansion joint is arranged at long rail string both ends, allows long rail string freely to stretch, to reduce rail internal temperature stress；It is fixed
The method that phase diffuses formula use is to unclamp intermediate fastening, anti-creep equipment in the range of designing fastening-down temperature of rail, take and hit rail method
Or train rolls equal measures and rail stroke, release internal rail stress is made then to relock circuit.
The above method has good effect for release rail internal temperature stress, but exists and lack real-time, puts
The process of dissipating is cumbersome, influences the limitations such as circuit normal operation, and when long rail string is flexible can drive rubber tie plate under rail to skid off, and cause
Guideway irregularity.Therefore, existing method has been unable to meet the requirement of high-speed railway.
Invention content
The purpose of this utility model is just to provide the simple in structure, safety and stability of one kind, it can be achieved that gapless track temperature stress
The fastener system of automatic relief ensures the stability of gapless track for realizing the automation that gapless track temperature stress is diffused
With the travel safety of bullet train.
A kind of fastener system of achievable gapless track temperature stress automatic relief of the utility model, including pedestal, rubber
Rubber cushion plate, integral type fastener, groups of springs, threaded spindle cap nut, which is characterized in that pedestal by the reserved bolt hole of bolt, sleeper with
Sleeper is fixedly connected, and base bottom is sequentially placed iron chair, height adjusting cushion plate, rubber mat plate, the upper ends band rolling of rubber mat plate
Pearl bottom plate, band ball side plate are respectively provided at base interior both sides, iron chair, height adjusting cushion plate, rubber mat plate, band ball bottom plate and band
Ball side plate is fitted tightly over base bottom surface and side respectively；Integral type fastener is pushed into base interior, bottom end and band along longitudinal direction
Ball bottom plate is in close contact, and side is in close contact with ball side plate；The both ends of pedestal longitudinal direction are respectively arranged with longitudinal folder
Plate, two longitudinal clamping plates are equipped with by being fastened on pedestal across the threaded spindle cap nut of pedestal preformed hole on the convex block of longitudinal clamping plate
Groups of springs, the groups of springs other side are in close contact with integral type fastener rear and front end；Rail passes through fastening elastic rod, rubber tie plate under rail
On integral type fastener.
A kind of fastener system of achievable gapless track temperature stress automatic relief of the utility model, operation principle
It is that due to the variation of temperature, the raising of rail temperature to generate temperature, pressure in long rail string, and the reduction of rail temperature to produce in long rail string
Raw temperature pulling force.The upper and lower surface of integral type fastener and side are in close contact with ball, constraint integral type fastener vertical and
Lateral displacement, longitudinal resistance mostlys come from the groups of springs on forward and backward longitudinal clamping plate, and the buckle press of fastening elastic rod is larger.
When rail internal temperature stress is larger so that rail drives rubber tie plate under rail and integral type fastener to slide in the longitudinal direction, this
When forward and backward longitudinal clamping plate on groups of springs deform, the longitudinal resistance provided line with the increase of groups of springs deflection
Property increase, rail can be limited to a certain extent and integral type fastener length travel is excessive.When rail temperature inverse change is to locking rail
Wen Shi, groups of springs elastic restoring force and rail expand with heat and contract with cold characteristic collective effect under, rail, rubber tie plate under rail and one
Formula fastener, which synchronizes, returns to initial position.The automation of gapless track long rail string internal temperature stress release, and not shadow are realized with this
Ring normal operation and the maintenance operation of circuit.
A kind of fastener system of achievable gapless track temperature stress automatic relief of the utility model and existing Sutureless
The road temperature stress technology of diffusing compares, and positive effect is can be tightly buckled in rail on the fastener system and allow
Long rail string generates certain length travel under the action of huge temperature stress, and rail temperature is restored to rail, rail when fastening-down temperature of rail
Rubber mat plate, integrated fastener can reset simultaneously again, realize the automation of gapless track destressing, greatly reduce maintenance
Workload effectively makes up some shortcomings existing for existing method, avoid gapless track expansion rail track caused by temperature stress,
The problems such as brittle fractures of rail.
