DIRECT LEAD-IN DEVICE FOR RIGID OVERHEAD CATENARY SYSTEM

摘要

PURPOSE: A connecting apparatus in the section of a catenary overhead line and a rigid electric railway line is provided to reduce the fatigue cause of the catenary overhead line and the electric railway line by alleviating stress generated from the movement of a pantograph. CONSTITUTION: An electric railway line fixing unit(10) fixes an electric railway line(20). A bracket(30) supports the electric railway line fixing unit. The electric railway line crosses a rigid electric railway line(40) installed on the ceiling of a tunnel by installing the bracket on the entrance of a tunnel. A stress alleviating unit(50) alleviates stress applied to the electric railway line fixing unit based on a pantograph which is moved in the contact states with respect to the electric railway line. The electric railway line fixing unit is composed of a fixing unit and a combining unit.
