RAIL VEHICLE FOR MOUNTING AND DISMOUNTING CONTACT SYSTEM WIRES AT PRESET TENSION AND METHODS OF WIRE MOUNTING BY MEANS OF THIS VEHICLE

摘要

FIELD: railway transport; mechanization of maintenance and repair works. SUBSTANCE: rail vehicle has self-propelled coupled platform carrying devices for reeling on/off of wires with drums and transit winches with drives. Device for lifting and fitting carrier cable and contact wires in mounting position is made in the form of ramp with two telescopic uprights and mechanism providing their coordinated vertical displacement. Two support-and-guide mechanisms to provided horizontal side travel of carriages are installed in upper portion of ramp. Contact wire support-and-guide rollers are mounted on one carriage, and support-and-guide roller of carrier cable and its vertical displacement drive are mounted on movable boom arranged on other carriage. Both mechanisms have independent drives. Such design of vehicle makes it possible to mount straight stagger and inclined overhead contact lines. EFFECT: possibility of mounting contact system wires without subsequent correction of fasteners and fixing members.
