摘要:
A method for installing railway tracks onto ballast beds avoiding the need for installing any type of auxiliary track. The method comprises successive stages to be carried out after having located the sleepers onto the ballast bed, consisting of fixing and laying of a pair of rails from a mini train, for the transport of the rails with the fastening and traction of same up to their complete unloading, the operation being guided by means of a discharge wagon; supporting the rails on rollers for the longitudinal movement thereof; cutting, squaring and fixing the adjacent ends to the consecutive rails; raising the rail with the help of a crane, and removing the rollers; partial fastening of the track and placement of the rollers for the next cycle, and removing the tractor from the mini train, and the final fastening of the rails.

A track position correction machine includes a multi-part machine frame and a satellite frame associated with the machine frame. A first drive displaces the satellite frame relative to the machine frame. A first packing unit and a track lifting unit are disposed on the satellite frame. A stabilization unit is associated with the machine frame. A second packing unit is disposed between the satellite frame and the stabilization unit. A second drive displaces the second packing unit relative to the machine frame.
摘要:
The invention relates to a gantry crane of a machine, for the exchange of sleepers on a track, which may be displaced in a machine longitudinal direction on crane tracks. Two crane buggies on the gantry crane, at a separation from each other in the machine transverse direction are embodied such as to be displaced relative to the crane chassis by means of a displacement drive for altering the gauge. The corresponding crane tracks may be adjusted in the track transverse direction by drives to change the gauge.

For the controlled lowering of a track, a longitudinal inclination of the track is determined at a rear tracing point of a measuring system and stored. For a length reaching back at least 10 meters, a current vertical profile is formed, and a rear compensation straight line is calculated which is superimposed upon the vertical profile and renders a target track position. The rear tracing point is guided by calculation along the rear compensation straight line, so that a compensation value for the position of the measuring chord ensues at a middle tracing point positioned between the rear tracing point and a front tracing point.

A device (1) for the application and/or for the removal of elements for the connection of a rail to a railway track sleeper, comprising at least one lever (2, 3) mounted on a frame (4) in a rotatable manner around an axis of rotation (5, 6), and equipped with at least one pressure organ (7, 8) adapted to engaging the connecting element, and at least one cylinder-piston group (9) adapted to driving the lever (2, 3) in order to assemble or disassemble the connecting element. The cylinder-piston group (9) comprises a cylinder body (10) and a sliding piston (11) housed within the cylinder body (10) and moveable with respect to the cylinder body (10) under the action of pressurised fluid. At least one first (12, 14) and second (13, 15) stop surfaces interact in such a manner as to form a stop device (16, 17) for stopping the lever (2, 3) in a defined position with respect to the frame (4), wherein the stop surfaces are formed, the one (12, 14) on the piston (11) and the other (13, 15) on the cylinder body (10) of said cylinder-piston group (9).
摘要:
In a method for efficiently removing a great number of damaged rail sections, after a first separating cut, the severed free rail ends are gripped by a rail pulling device connecting the rail ends to one another, and are pulled towards one another. The pulling force required for the pulling-together as well a current rail temperature are registered for calculation of that length of a replacement rail which is required for producing a desired rail tension. A second separating cut is carried out—with corresponding path measurement—spaced at a distance from the first separating cut as calculated on the basis of the selected length of the replacement rail.
摘要:
A device (1) serves for installing rail clips (4) and consists of two tool levers (5) positioned opposite one another and supported on a tool frame (6) by means of a squeezing cylinder (7) in the transverse direction of the machine or track and movable about a pivot bolt (17) of a lever bearing (11,12). Provided at the lower end (8) of each tool lever is a pressing member (9,10) provided for application to a rail clip (4). Each tool lever (5) comprises a first and a second lever bearing (11,12) spaced from one another in a transverse direction (15) extending perpendicularly to pivot axes (13,14). These lever bearings serve for pivoting, as desired, about the first or the second pivot axis (13,14).

A rail loading train for transporting as well as loading and unloading long rails, includes a number of loading cars coupled together and having a frame which has a longitudinal axis and is supported on undercarriages for movement in an operating direction. Mounted on the loading cars are a plurality of rail supports which are spaced from each other longitudinally in direction of the frame and respectively rotatably mounted on support columns. Each rail support includes a separate pivot drive for swinging the rail support about a vertical axis between a receiving position in which the rail support extends perpendicular to the longitudinal axis and an idle position in which the rail support extends in direction of the longitudinal axis, whereby the position of the rail support in each end position is automatically secured by a locking mechanism once the swinging motion is concluded.
摘要:
A mobile apparatus for loading and transporting an assembled track section and for laying the track section on a track bed comprises a track section hoisting device comprising an elongated carrier frame extending in the longitudinal direction of the track bed, pairs of lifting jacks spaced from each other in said direction, and drives for vertically adjusting the lifting jacks between a retracted position and an extended position in which the lifting jacks support the carrier frame on the track bed. An elongated transport car for supporting an assembled track section and the hoisting device is movable in this direction independently of the hoisting device. The elongated carrier frame and transport car each are comprised of two parts connected by a pivot between their opposite ends for pivoting the parts relative to each other about a vertical axis. Track-bound undercarriages and vertically adjustable off-track undercarriages are arranged adjacent each end and the pivot of the transport car, and one of the pairs of lifting jacks is arranged adjacent the pivot of the carrier frame.
