SWING BRIDGE Russian patent published in 2003 - IPC

FIELD: bridge construction. SUBSTANCE: swing bridge includes framework on which lower plane supporting wheels are anchored on axles and support. Ferromagnetic barrel is made fast to lower plane of framework with bottom facing downwards. It has central hole inside which L-shaped ferromagnetic trusses with holes accommodating location lockpins are uniformly placed over circumference which are made fast to support. Electromagnetic coils which windings are connected to output stabilization facility are wound on lower ends of trusses. Inputs of stabilization facility that is coupled to power supply system are connected to pickups indicating clearance between bottom of ferromagnetic barrel and lower surfaces of L- shaped trusses. Location lockpins and ferromagnetic arc are fixed in lower plane of ferromagnetic barrel. Stator of arc electric motor is mounted on upper parts of L- shaped ferromagnetic trusses. EFFECT: raised operational reliability of swing bridge. 3 dwg
