Description
Technical field
The utility model relates to railway traffic equipment, especially a kind of magnetic sand filled-type compensates steel sleeper.
Background technique
Currently, the development of China railways must be premised on high stationarity, high-comfort, high security, therefore, it is necessary to protect
Demonstrate,prove the high stability of sub-rail foundation.Influence of the sub-rail foundation sedimentation to sub-rail foundation stability is very significant, and route is in the operation phase
Between there is the problems such as local subsidence, differential settlement and will seriously affect travel safety and passenger's comfort.When train height
When speed passes through, vehicle-rail interaction forces aggravation causes route to generate irregularity, accelerates the deterioration of track circuit state, contracting
In the maintenance period of short track circuit, increase the maintenance cost of track circuit, driving peace is very likely threatened when serious
Entirely.
Often multiple positions generate jointly again for the formation of rail track sub-rail foundation sedimentation, and many factors are coefficient
As a result, the position settled is predominantly located at bedding position, ground position and railway roadbed position, and influence factor mainly have it is following several
Kind: 1. sedimentation caused by structural factor；2. sedimentation caused by extraneous effect of natural environment；3. sedimentation caused by human activity；④
Regional subsidence caused by level of ground water；5. differential settlement caused by changeover portion difference.Cause rail track settle five kinds
In factor, and with uneven caused by sedimentation caused by sedimentation caused by structural factor, extraneous natural cause and changeover portion difference
It is especially prominent to settle these three.And the position that Settlement diseases generate is mostly based on ground and bedding bottom.For ground and bedding
The regulation method of deep settlement mainly has local change to fill out method for strengthening, compaction pile method for strengthening, Geotechnical Composite Materials in Strengthening method and note
Starch method for strengthening etc..
For the mutation for reducing route rigidity between different line constructions, need non-fragment orbit and Ballast track, roadbed with
Changeover portion is arranged in the junction of bridges and culverts, roadbed and tunnel and embankment and cutting, to realize transition segment limit interior lines road rigidity gradually
Become transition.The common processing method of changeover portion has: one, in the softer side of changeover portion, increasing bedding rigidity, reduce Embankment Subsidence.
Specific processing method has following several: 1. rubble class quality material fills method；2. reinforcement local method；3. preferable using mechanical property
Lightweight material, such as: EPS, artificial cellular concrete etc.；4. transition plates method；5. being located at the changeover portion of soft clay area, can also examine
Worry is filled using light material, such as two-ash soil other fillers.Two, in the softer side of changeover portion, increase track vertical rigidity.Tool
Body processing method has following several: 1. enhancing track vertical rigidity by adjusting the spacing between length of sleeper and sleeper；②
Orbit rigidity is improved by increasing section of track rigidity；3. improving orbit rigidity by thickening thickness of ballast bed.Three, changeover portion compared with
Hard side reduces track vertical rigidity.Specific processing method has: the 1. rubber softer by the rail underlay in track circuit
Pad；2. in sleeper underlay high elastic rubber pad；3. increasing on bridge, railway ballast thickness in tunnel；4. overlaying railway ballast pad etc. to adjust rail
Road vertical rigidity.
Above-mentioned measure method is for reducing the stiffness variation rate between the sedimentation of route and different line constructions with good
Effect, but not can solve settlement of subgrade cause two sides rail track irregularity problem and by between different structure because of poor rigidity
Caused rail level bends problem, and lacks automaticity and real-time, and remedial technology technique is cumbersome, expends a large amount of maintenances
Financial resources and manpower, therefore there is certain limitation.
Summary of the invention
The purpose of this utility model is just to provide that a kind of structure is simple, can the magnetic sand filled-type of stepless automatic adjustment compensate steel
Pillow.
The magnetic sand filled-type of the utility model compensates steel sleeper, including steel sleeper, load-bearing elevator, bolt, rail pass through fastener
It is connect with load-bearing elevator, which is characterized in that load-bearing elevator lower end is equipped with four support columns being symmetrically spaced, support column difference
It being inserted in firm banking in symmetrical four to match groove, groove vicinity is magnetic sand chamber, magnetic sand is filled in magnetic sand chamber,
Magnetic sand chamber bottom opening, opening setting circular magnet block and holds magnetic sheet, and firm banking holds magnetic sheet and is bolted on steel sleeper
Bottom.
The magnetic sand filled-type compensation steel sleeper working principle of the utility model is that, when train wheel passes through, wheel is to rail
The active force of generation via under load-bearing elevator, load-bearing elevator support column, magnetic sand, magnet block, hold magnetic sheet and steel sleeper bottom
It reaches on railway roadbed, the magnetic sand in the support column and firm banking under load-bearing elevator is in close contact at this time, and steel sleeper is together with rail
Movement.If railway roadbed settles, rail will generate downwards elastic bending deflection, when train wheel leaves, the elasticity of rail
Recoverable force generates a very big upward elastic force, i.e. rail drives load-bearing elevator to move upwardly together, at this point, load-bearing
It is disengaged between magnetic sand in the support column and firm banking of elevator lower part, i.e. the bearing column bottom of load-bearing elevator lower part
There is gap, the magnetic sand inside magnetic sand chamber is under Gravitative Loads immediately and magnet block is to can be along support column under its magneticaction
Surface landing forms new mechanics so that the magnetic sand in firm banking is stuffed entirely with full until being filled up completely bearing column bottom
Equilibrium system, i.e. support column under load-bearing elevator are stationary, and the amount of shifting up of load-bearing elevator just compensates for railway roadbed
Settling amount.When train wheel again passes by, the magnetic sand in the support column and firm banking under load-bearing elevator is in close contact,
The active force transmitted downwards will not change the relative position in support column and firm banking under load-bearing elevator between magnetic sand, wheel
To rail generate active force still via under load-bearing elevator, load-bearing elevator support column, magnetic sand, magnet block, hold magnetic sheet
It is reached on railway roadbed with steel sleeper bottom.If railway roadbed does not generate sedimentation, the whole height of device is constant, if railway roadbed sinks at this time
Drop, then repeat above-mentioned adjustment process again.When find load-bearing elevator be higher by initial position it is a certain amount of after, can be by manually turning
Fixing bolt, magnetic sheet and magnet block are held in taking-up, so that the magnetic sand inside magnetic sand chamber is slowly poured out in Gravitative Loads, load-bearing liter immediately
The support column of drop block lower part is gradually restored to initial position；Then, it installs magnet block and holds magnetic sheet, and then tighten fixed spiral shell
Bolt；Finally, magnetic sand is uniformly injected into magnetic sand chamber from the reserved note sand hole of firm banking upper end, until filling full, reset work
It completes.
The magnetic sand filled-type of the utility model compensates steel sleeper, utilizes the Gravitative Loads and magnet block pair of magnetic sand chamber inner magnet sand
Its magneticaction automatically adjusts rail height, compensated foundation sedimentation, it is tied by the trigger action of steel rail spring restoring force
Structure is simple, is able to achieve stepless automatic adjustment.
