Description
Technical field
The present invention relates to track support means, especially four rail support devices.
Background technology
The Traction networks of Feeding System of Urban Rail Transit are made of contact net and reflux net, and contact net is anode, reflux
Net is cathode, is connect respectively with traction substation.Urban rail transit in China is all made of rail as return current rail at this stage.
Under this power supply mode, since rail can not possibly be completely insulated in railway roadbed, traction current electric current will be passed through inevitably
Rail generates stray electrical current to railway roadbed and other structures leakage.Stray electrical current is to rail, solid concrete roabed structure reinforcing bars, civil engineering
Metal equipment along structure reinforcing bars and subway will all generate corrosion, to influence subway rail, structure reinforcing bars and metal
The service life of equipment.Although considering that stray electrical is arranged in solid concrete roabed and structure reinforcing bars in previous electric power supply system for subway
Collecting net is flowed to reduce corrosion of the stray electrical current to metal structure, but stray current corrosion safeguard procedures can only reduce stray electrical current
To metal erosion degree, it can not be fully solved the corrosion impact of stray electrical current, with the increase in operation age, stray electrical current will
Increasing, consequence is very serious.It is based on and avoids this thinking of the adverse effect of stray electrical current, seeking one both at home and abroad
The reliable backflow model of kind.

Ensure the relative position of upper clipping claw and track.
6 nylon sliding rail bottoms are equipped with two dove-tail form splines, and corresponding all nylon sliding rail installation pits are equipped with dovetail
Slot, the two Matching installation are smooth after the wedge surface guarantee sliding rail installation that dovetail is formed not tilt.
7 middle part decks, installation supporting plate place boss at track, and shape is similar to the waist of track, while good guidance
Reduce track clamping stagnation.
It does fluted at 8 middle part deck shapes, increases the creepage distance between two rails after installation, ensure compact-sized
Meet electrical insulation properties simultaneously.Middle part fixture block uses inline fastener form, ensures the insulating part table under smaller installation space
Face creep distance and install convenient.
