For achieving the above object, the technical solution adopted in the utility model is: a kind of tram elasticity separated rail fastening, comprise iron chair, rail is placed on iron chair, the left and right sides of rail all is equipped with anchor bolt, spring, T-shaped bolt and L shaped Insulation rail distance keeper on iron chair, and iron chair is fixed on sleeper through anchor bolt;
Place successively from top to bottom height adjusting cushion plate under rubber mat plate and rail between described rail and iron chair, place successively from top to bottom heightening base plate under iron base plate and insulating pad between described iron chair and sleeper;
The described iron chair left and right sides is equipped with boss, T-shaped bolt pierces into boss spring is fixed on iron chair, the forelimb of spring is withheld on rail through the horizontal edge of L shaped Insulation rail distance keeper, and afterbody is resisted against on boss, and the vertical edge of L shaped Insulation rail distance keeper is folded between rail and boss;
Offer slotted hole on described iron chair, its hole major diameter is greater than the screw rod external diameter of anchor bolt, and the hole minor axis is more than or equal to the screw rod external diameter of anchor bolt, and the screw rod of anchor bolt passes from this slotted hole, iron chair is fixed on sleeper.
Related content in technique scheme is explained as follows:
1, in such scheme, under described L shaped Insulation rail distance keeper, insulating pad, rubber mat plate, heightening base plate under iron base plate and rail, height adjusting cushion plate is insulation fabric part.
2, in such scheme, be provided with spring washer between the head of described anchor bolt and iron chair.
3, in such scheme, the sleeve pipe of described anchor bolt through being embedded in advance in sleeper is connected with sleeper, and sleeve pipe is insulation fabric part.
The utility model operating principle is: gauge adjustment has dual mode: one, offer slotted hole on iron chair, the screw rod of anchor bolt passes from this slotted hole, after unscrewing anchor bolt, and removable iron chair, the rail that the drive iron chair carries moves horizontally, and carries out gauge adjustment; Two, change two L shaped Insulation rail distance keepers of rail both sides, the vertical edge of the L shaped Insulation rail distance keeper of one side thickens, and the vertical edge of the L shaped Insulation rail distance keeper of opposite side, with regard to corresponding attenuation, also can carry out gauge adjustment.
Rail Height Adjustment:, by height adjusting cushion plate and/or heightening base plate under iron base plate under the rail of changing different size (different-thickness or height), can carry out the rail Height Adjustment.
Insulation effect: under Insulation rail distance keeper, insulating pad, rubber mat plate, heightening base plate under iron base plate, rail, height adjusting cushion plate and sleeve pipe etc. all adopt the low insulation materials of conductance to make, and are insulation fabric part, have greatly improved the insulation effect of whole fastener system.
In addition, after unscrewing anchor bolt, but iron chair and on all component integrated movings, therefore when assembling, can assemble iron chair and on component, then carry out all-in-one-piece Installation and Debugging, easy for installation, alignment error is little.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, because the utility model employing anchor bolt, spring, T-shaped bolt etc. carry out fastening, fastening effective to the tram rail.
2, owing to offering slotted hole on the utility model iron chair, unscrew removable iron chair after anchor bolt, or change the L shaped Insulation rail distance keeper of different size, all can carry out gauge adjustment, the adjustment mode is flexible.
3,, owing to the utlity model has height adjusting cushion plate under heightening base plate under iron base plate and rail, can carry out the rail Height Adjustment, adjust flexible.
4, owing to offering slotted hole on the utility model iron chair, unscrew all component of removable iron chair after anchor bolt and upper carrying thereof, therefore make to add and can go to again job site to install after factory-assembled is good man-hour, can control alignment error, improve installation accuracy.
