Description
Technical field
The utility model belongs to railroad track engineering device technique field, and in particular to one kind is suitable for gauge changing railway freight and arranges
The 1435/1520mm gauge orbit transfer linkage section of vehicle.
Background technique
Currently, worldwide having carried out a plurality of railway international combined transport and regional transportation corridor, mainly there is Eurasia
Land bridge, pan-European rail channel, Trans-Asia railway channel and North America railway transportation channel.But due to numerous, above-mentioned channel edge
The state-owned railroads that line is passed through have a variety of different gauges, if Eurasia Land Bridge is from China Shanghai, Lianyun Harbour to Europe
Amsterdam of West Coast, 1.1 ten thousand km of railway line overall length are divided into northern line, middle line and southern line, and the China and Europe in northern line are each
State is all standard gauge (gauge 1435mm), and Mongolia, Russia, Byelorussia are broad gauge (gauge 1520mm).This gives
The development of international combined transport brings inconvenience.
Due to history, the railway in country variant and area uses different gauge specifications.In train by not
With gauge specification railway when, preferably use gauge-changeable bogie to improve conevying efficiency.The wheel of gauge-changeable bogie is in axle
It is adjusted in axial direction, to realize that the wheel of transformation bogie adapts to wheelspan different gauges.Currently, for using people in industry
The mode of power realizes that gauge is converted.Specifically, gauge-changeable bogie is jacked up by support device, unloads wheel, then passed through
Manually wheel is installed to another specification.This gauge conversion regime inefficiency is brought many to development international combined transport
Limitation.
Recently as being pushed further into for Highs-speed motor train unit bogie gauge changing technology, notification number is CN 107574728
The Chinese invention patent application of A discloses a kind of gauge conversion equipment, including supporting rail, unlock rail and guided way, supporting rail packet
It includes support preparation rail and supports and continue rail, unlock rail includes unlocking preparation rail reconciliation to lock continuous rail；Preparation rail is supported to form support
Section；Lasting rail and unlock preparation rail is supported to be formed and unlock section；It supports and continues rail, unlocks lasting rail and guided way formation guide section.
The patented technology is introduced technology derived from the external gauge changing device for high-speed EMUs, and the bullet train suitable for short marshalling becomes
Rail operation after bogie enters ground gauge conversion equipment, in supporting section, supports preparation rail that the wheel of bogie is carried mould
Formula is converted to axle box or other bearing modes, unloads wheel, incites somebody to action at train axle box position or in bogie on portion mechanism at this time
In the presence of the whole load for being transferred to compartment, train traffic safety will be seriously threatened for the goods train of heavy duty, weakening turns
To the service life of frame, obstacle is brought for international combined transport.In unlock section, lasting rail is supported persistently to keep axle box supporting way, wheel is held
Unloaded state is held in continuation of insurance；And unlock preparation rail and gradually start unlock piece, until reaching unlocked state, wheel is in free at this time
State can slide axially.In guide section, lasting rail is supported persistently to keep axle box supporting way, i.e. wheel persistently keeps unloading
State；It unlocks lasting rail and persistently keeps unlocked state, is i.e. wheel is in free state；Guided way is by wheel from a kind of gauge specification
Another gauge specification is converted to, the conversion of gauge is realized.Rail vehicle is becoming rail changeover portion change rail vehicle in sliding fortune
Row state, it is huge to side change rail orbital facilities abrasion, it is more serious to the abrasion of train bogie axle box and dependency structure, after
Phase operation maintenance maintenance is more difficult.Need at the same time to have more operation vehicle attach unified bogie gauge changing mechanism,
Manufacture installation cost is high, and vehicle axle weight further increases., trade frequent " Silk Road warp huge for the rotation volume of goods transport
For Ji band " channel, which does not have a wide range of significance of application.
Notification number is the Chinese invention patent application of 107571685 A of CN, discloses a kind of train wheel, exactly
It is to adapt to train wheel of the double track away from rail, is that railway train wheel tread is designed as step.It is straight to propose different gauge rail
For line symmetrically without difference in height docking is sewed with, it is poor that broad gage rail is higher by two tyre tread radius of circle of wheel.When train is in standard-gauge rail
When driving, great circle tyre tread is contacted with rail.When train broad gage rail when driving, roundlet tyre tread is contacted with rail, and great circle is stepped on
Face is oriented to train operation at wheel rim.Require high in wheel design manufacture at this time, applicability is poor, be related to gauge difference compared with
Big connection then requires designed wheel tread wider, will occur in normal walking tight for that can connect transition operation
Weight unbalance stress, oscillation crosswise and serpentine locomotion phenomenon are more prominent.
