Automatic machine for leveling and alignment of railway in plate, prior to the concrete

A machine for leveling and alignment of a section of ballastless railway track having two rails joined through fasteners to connecting elements, comprising:

• a structure comprising a main body and a secondary body coupled to the main body and movable laterally relative to the main body,
• the main body comprising a plurality of lift cylinders for lifting the structure, having an upper end connected to the main body and a bottom for contacting the ground;
• the secondary body comprising a plurality of wheels for movement of the structure along a track, two fastening elements to firmly grab each of the two rails, once situated in the section, for lifting and suspending the rails and connecting elements that make up the track,
• a plurality of relaying hydraulic cylinders coupled to the main body and the secondary body, for lateral movement of the secondary body relative to the main body,
• such that when the main body is raised by the plurality of lift cylinders, the rails and connecting elements are suspended, the secondary body is moved laterally by the plurality of relaying hydraulic cylinders, displacing the track, leveling and aligning the track;
• and when the main body is lowered by the plurality of lift cylinders, the rails and connecting elements are placed in a desired final position;
• a measuring system, comprising a plurality of tilt sensors for sensing a relative position of the track in real-time, and a total station for acquiring data relating to absolute position of the track, such that an actual position of the track is determined in real time;
• a control system comprising a processor having software for processing position of the track acquired by the tilt sensor and the total station, comparing the actual position of the track with a desired final track position, obtaining as a result the difference between the desired final track position and the actual track position, and determining the lateral movement of the secondary body on the main body needed to achieve the desired final track position, such that the processor controls the hydraulic lift cylinders and the relaying hydraulic cylinders such that the machine carries out the required movements.
