Patent
Harsco | Date: 2015-04-21

A device and method for the replacement of railroad ties is disclosed. The tie extends laterally under two rails and is attached to the rails via tie plates. An example rail changing machine includes a tie changing boom moveable to one side of the two rails. The tie changing boom including a gripping assembly for clamping the railroad tie. The tie changing boom is moveable between a proximate position and a distal position from the one side of the two rails to grip the tie and remove the tie from under the rails. A kicker is located on the opposite side of the rails from the tie changing boom and contacts one end of the tie to move the tie toward the tie changing boom. A pair of tie plate clamps to hold the tie plates in place when the kicker moves the tie.

In an aspect, a track maintenance vehicle includes a body, a work head, and a controller. The work head performs track maintenance and is coupled to the body. The controller is configured to operate the vehicle in an autonomous mode. In another aspect, an anchor adjustor includes first and second jaws and an actuator. The jaws pivot about a single axis. The actuator causes the jaws to rotate about the axis. In another aspect, an anchor adjustor assembly includes a first pair of jaws, a second pair of jaws and an actuator. The first and second pairs of jaws open and close about a rail in a track. The actuator causes the closed first pair of jaws to translate towards the closed second pair of jaws along a longitudinal direction of the rail.

A rail vehicle includes a rail vehicle frame, a pocket, a first beam, a second beam, an endplate, an actuator and a workhead carrier. The pocket is coupled to a frame portion of the rail vehicle frame. The first beam is disposed in a cavity defined by the pocket. The second beam is disposed proximal to the first beam. The end plate couples the first beam and the second beam. The actuator extends the first and second beams such that the end plate is displaced transversely with respect to the rail vehicle frame. The work head carrier is operable to translate along the first and second beams and couple the second beam to the frame portion.

The present disclosure generally relates to a workhead assembly for use in rail applications and associated methods of use. The workhead assembly may comprise a frame and two pairs of workheads, wherein each pair of workheads is disposed on opposing sides of the frame and carries tamping tools. The workhead assembly may further include two vertically-oriented actuators being disposed on opposing sides of the frame. Two pairs of linkage arms are coupled between the vertically-oriented actuator and a pair of tamping arms. Each pair of linkage arms are disposed on opposing sides of the frame. Actuation of the linkage arms imparts movement to the tamping tools.

The present disclosure generally relates to a rail warning system using wireless portable transmitters/receivers. The rail warning system uses a chirp spread spectrum modulation scheme, and alerts personnel in work zones on or near train tracks as well as optionally, on track equipment and train operators, of approaching trains or on track equipment. Portable wayside devices may also be positioned on the rail web, optionally magnetically, to alert work personnel, allowing for secure placement but also portability to other locations on the same track or adjacent tracks.


Patent
Harsco | Date: 2015-11-25

A personnel warning system producing a signal when sensing the presence of a train for use by railroad workers including the steps of providing a train detection device having at least one magnet thereon, attaching such train detection device quickly and easily to the train track in the work area where maintenance is to be performed, providing each of the workers with a personal alert receiver for receiving such signals for warning to the workers of an oncoming train, quickly detaching such train detection device when desired and repeating the steps of attaching, and detaching such train detection device when moving the train detection device to subsequent work areas. Also disclosed is a train detection device having at least one magnet disposed on a side thereof.
