Self-propelled machine and method for laying a catenary and/or a contact wire of an overhead line

摘要

A self-propelled machine for continuously laying an overhead line extending above a track and attached to pylons spaced alongside the track, which comprises machine frame movable along the track in an operating direction, a power-driven, vertically and laterally adjustable work platform mounted on the machine frame for an operator assigned to attaching the overhead line to the pylons, a storage drum mounted on the machine frame, a length of the catenary and/or the contact wire of the overhead line being reeled on the storage drum and the drum being rotatable at a pay-out speed for unreeling the catenary and/or the contact wire, and a drive control for adjusting the moving speed of the machine frame in response to the pay-out speed of the catenary and/or the contact wire. A lifting device is mounted on the machine frame and includes a power-driven, vertically adjustable and laterally pivotal boom, and a support and guide pulley carried by the boom and arranged to support and guide the unreeled catenary and/or contact wire from the storage drum to the operator on the work platform at a constant height determined by the vertical adjustment of the boom and a lateral position determined by the pivoting of the boom, and a device is mounted on the machine frame between the storage drum and the pulley for continuously guiding and tensioning the catenary and/or contact wire, the guiding and tensioning device including a power-driven guide roller guiding the tensioned catenary and/or contact wire to the support and guide pulley, and a drive control for the guide roller.
