HIGHWAY-RAILWAY DUAL-PURPOSE TRACK-LAYING MACHINE FOR URBAN RAIL TRANSIT ENGINEERING

摘要

A highway-railway dual-purpose track-laying machine for an urban rail transit engineering, comprising a framework structure, a traveling mechanism, and a hoisting system. The framework structure comprises a framework; the framework comprises a side framework structure and an upper connection framework structure; the side framework structure comprises a lower fixed structure and an upper movable structure; the upper movable structure can stretch out and draw back with respect to the lower fixed structure; the upper connection framework structure comprises a fixed structure and a movable structure; the movable structure can stretch out and draw back with respect to the fixed structure; the traveling mechanism is connected to the framework structure and used for achieving the movement of the framework structure; and the hoisting system is provided on the framework structure and used for hoisting. The combined structure of the track-laying machine is simple and feasible; the traveling and track gauge change structure of the highway-railway dual-purpose track-laying machine for the urban rail transit engineering and a structure for achieving whole machine span change are separately designed, and the traveling mechanism is designed to be a height and position adjustable structure, and thus, corresponding change requirements can be realized according to working condition requirements.
