Description
Technical field
The present invention relates to a kind of telescopic connector for track traffic conductor rail system.
Background technology
Telescopic connector is also known as expansion pipe, is that the machinery for being used in conductor rail system set up in the middle of adjacent anchor section breaks
Mouthful, making the conductor rail of its both sides can freely expand with heat and contract with cold along longitudinal centre line and keep electric current unobstructed, and can be flowed train
The device of the uninterrupted power taking of device.Therefore the expansion joint setting of expansion pipe is very crucial.It is flexible that conventional contacts rail system is used
Formula connector has the forms such as single seam, double slit, wherein single slit formula（It can be seen that Chinese patent CN 201220221998.4）It is used for connecing
Rail-engaging system is expanded with heat and contract with cold not acutely or the longer operating mode of pantagraph current collector slide plate, and when expanding with heat and contract with cold violent, the spacing at expansion joint becomes
Change is larger, damages serious to vehicle pantagraph current collector；In view of the defect of single slit formula, double slit form is just released（It can be seen that China
Patent CN201120170995.8, CN201320307088.2）, the type telescopic connector mostly taken in two conductor rails section
Between add the form of a mid-rail, two of which conductor rail section is by elongated hole connection anchoring clamping plate, and mid-rail is then and anchor
Gu clamping plate is fastenedly connected, two conductor rail sections ensure that conductor rail has enough strokes by foregoing elongated hole.Therefore the type connector
Single seam is changed into double slit, its clearance of expansion rail changes smaller under the influence of temperature, therefore solves adaptability of acutely expanding with heat and contract with cold and ask
Topic, more conducively pantagraph current collector is passed through, but this connector but has the defect that mid-rail is easily offset, i.e. mid-rail and anchoring
Clamping plate is fastenedly connected as rigid body, but can with respect to two conductor rails section activities, when pantagraph current collector by or temperature change make centre
Rail, which is climbed, moves to one side, will make double slit disabler, therefore easily damages pantagraph current collector, and greater risk will be caused to the normal operation of vehicle.
The content of the invention
The application purpose is to provide a kind of telescopic connector for track traffic conductor rail system, can effectively carried
The compensation effect that height expands with heat and contract with cold to conductor rail, reduces influence of the expansion joint to pantagraph current collector, ensure that pantagraph current collector is smoothly slipped over
Telescopic connector, while eliminating the defect that convention connectors mid-rail is easily offset to side.
To achieve the above object, telescopic connector of the invention, at least including two conductor rail sections, mid-rail, spacing leads
Xiang Ti, electric conductor；The spacing guide way and two conductor rails section, mid-rail are connected respectively, make two conductor rails section and mid-rail it
Between at least form two expansion joints；Two conductor rails section and mid-rail electrical connection electric conductor realize electrical conduction；Two conductor rail Duan Yuzhong
Between rail working face in the same plane；Two conductor rails section and mid-rail are constrained by spacing guide way, it is only capable of along length side
To being subjected to displacement；Characterized in that, the cooperation that a transmission bar is acted in mid-rail is at least connected with two conductor rails section respectively
Device；When the displacement that length direction occurs for two conductor rails section causes expansion joint to change, adapting device in mid-rail by
To the active force of transmission bar, evenly distribute the expansion joint of mid-rail both sides.
On the basis of above-mentioned technical proposal, driving member is rack, and mating component is gear, and gear is assemblied in by axle
In mid-rail.
On the basis of above-mentioned technical proposal, driving member is connecting rod, and mating component is swing rod, and swing rod is assemblied in by axle
In mid-rail.
On the basis of above-mentioned technical proposal, driving member is connecting rod, and it is connected with conductor rail section with revolute pair, coordinates structure
Part is the sliding groove in mid-rail.
Driving member is spring, and it is connected with conductor rail section, and mating component is the installation foundation of spring.
The beneficial effects of the invention are as follows,
1st, telescopic connector uses double slit form in the application, then the relative spacing at one expansion joint is exhausted much smaller than connector
To spacing, adverse effect of the expansion joint to pantagraph current collector can be reduced, raising is acutely expanded with heat and contract with cold to conductor rail system operating mode and is flowed
The adaptability of device；
2nd, telescopic connector constrains the motion of mid-rail using transmission mechanism in the application, eliminates the telescopic connection of traditional double slit
The defect that the mid-rail of device is easily offset.
