摘要:
A maintenance vehicle has side walls for creating a work space, delimited by the same, for working personnel situated on a track. The side walls are arranged on a vehicle frame and configured to be distanced from one another in a transverse direction of the vehicle. For treatment of a track section situated within the work space, an industrial robot is arranged on the vehicle, having at least three motion axes, media couplings for energy supply as well as a tool coupling for selective connection to a track treatment tool.

The invention relates to a pulling machine for unloading and laying railway tracks, which moves by means of caterpillar tracks running next to the sleepers arranged on the setting bed, with the rail on the provisional supports arranged on the sleepers. The machine comprises a cabin and two caterpillar tracks and includes, in its rear tractor part, a pulling slide that comprises a tube with fastening elements, said tube sliding horizontally, actuated by a hydraulic cylinder comprising a piston connected to the tube, via three dismountable metal supports provided with teflon elements for facilitating the sliding, said metal supports being connected to steel elements acted upon by articulated arms generating the vertical movement by means of the action of another hydraulic cylinder, always maintaining the pulling direction. The machine pulls the rails without needing an auxillary track, maintaining the position of the track-laying train.

A rail guide for loading railroad rails onto a rail train. The rail guide includes a guide beam disposed to depend vertically downward over each shelf in a rack on a rack car. The guide beam extends substantially the length of the rack car and is coupled to a corresponding guide beam of an adjacent car via a bridge that is configured to accommodate relative movement between the cars. A shoe is provided that is coupled to a leading end of a rail to be loaded. The shoe includes a follower that engages the guide beam to guide a rail being loaded along a path defined by the guide beam. The guide beam can provide vertical and lateral support to the leading end of the rail during loading.

A rail guiding tool used for aligning rails for railroad construction. The present invention provides railroad constructions workers with a tool that distances themselves from the suspended rails. The railroad construction workers use the present invention to align each rail together by means of a guide plate and an elongated handle. The guide plate is able to engage the head of rails, while the construction worker maneuvers the rail with the handle.

A method is being described for the installation of railway tracks onto ballast beds, which avoids the need for the installation of any type of auxiliary track. The method simplifies the method of operation of the current state of the technique in an appreciable manner, and contains the successive stages carried out after having located the sleepers onto the ballast bed, consisting in a summarised form of the 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; the support of the rails on longitudinal movement rollers; the cutting, squaring and fixing of the adjacent ends to the consecutive rails; the raising of the rail with the help of a crane, and the removal of the rollers; partial screwing of the track and placement of the rollers for the next cycle, and the removal of the tractor device from the mini train, and the final screwing.

A machine (1) for picking up and storing rail fastenings (2) of a track (3) includes two rail fastening pickup devices (9). Arranged between these and a rear on-track undercarriage (4)—with regard to a working direction (6)—is a crawler track (24). At each longitudinal side of the machine, two devices (29) for guiding rails (30) are provided which are adjustable by drives (28) relative to the machine frame (5) and arranged one following the other in the longitudinal direction of the machine.
摘要:
A continuously advancing dynamic track stabilization machine comprises a first cross level measuring element arranged at the machine frame front end and generating reference signals corresponding to the measured cross level at successive points as the machine continuously advances, a second cross level measuring element arranged adjacent a track stabilization assembly spaced from the front end and generating a signal corresponding to the measured cross level, and a control for actuating the drives for applying a vertical load to the track rails and for vibrating the track in a horizontal, transverse direction. The control is arranged to receive the reference signals from the first cross level element, to store the received reference signals until the second cross level element has reached the successive points, to compare the stored reference signals with the signals generated by the second cross level element to obtain a control signal, and to transmit the control signal for actuating the drives.
摘要:
An apparatus for reducing a gap between an end of a rail section and an adjacent end of a longitudinally succeeding rail section of a rail fastened to ties by fastening elements by tensioning or longitudinally extending the rail section comprises two longitudinally spaced beams extending transversely to the track rails, a pair of clamping members mounted on each transverse beam for pivoting about parallel vertical axes at respective sides of the rail sections of the rail and having cooperating clamping jaws for engaging the rail sections between the clamping members upon pivoting thereof, the pairs of clamping members being longitudinally spaced from each other, hydraulic drives interconnecting the clamping members at each side of the rail sections of the rail, and a rail centering mechanism affixed to each transverse beam in the range of each pair of clamping members, each rail centering mechanism comprising at least two independently operable hydraulic cylinders carrying rams adapted to be pressed against at least one of said track components of the rail upon operation of the hydraulic cylinders.
摘要:
A rail roller device constructed to include a cylindrically shaped roll surface, the ends of which are provided with radially extending end plates or flanges from which extend the roller shaft. Opposite ends of the roller shaft extend through steel ball bearings mounted within mounting brackets which are fixedly attached to the device frame. At least one retaining ring is located about the shaft between a ball bearing and an end plate. The generally rectangular shaped frame of the rail roller device is formed of four frame members each constructed from a length of angle iron. The frame is constructed so that a pair of frame members located parallel to the longitudinal axis of the roll surface can be set between rail ties.

A frame comprises cross-members. Two longitudinal beams are associated with the frame. At least one of the beams is detachably associated with the cross-members. An arm extends transversely to the beams between the same and is pivotally connected to the frame by an articulated joint. A drive mechanism is provided to impart a pivotal movement to the arm about the articulated joint. Upwardly facing, low-friction bearings are carried by the arm between the beams and spaced from the articulated joint. The frame is adapted to be pushed under a rail and to assume a condition in which the beams extend along the rail on opposite sides thereof and rest on two spaced apart ties supporting the rail and the bearings engage the rail from underneath between the ties.
