MACHINE FOR RAIL CONTACT BUTT WELDING Russian patent published in 2014 - IPC B23K11/04 B23K101/26

Abstract RU 2503525 C2

FIELD: process engineering.

SUBSTANCE: invention relates to rail welding machine and can be used for welding separate rails, long rail sections and repair of tracks in the field. Two jar clamps are composed of two isolated double-arm levers fitted on common axle. Machine includes hydraulic cylinders for clamping and transfer of parts being welded. Two welding transformers are built in double-arm levers of one of said two jaw clamps. Current feed elements comprises rods and displacement and shrinkage, electric contact clamps and flexible jumpers. Said electric contact clamps are furnished with controlled drives. Top part of every said electric contact clamp has holes for guide rods to pass there through while its side surface has locking spring.

EFFECT: stable electric circuit and welding, high quality of welded joints.
