| 20110072998 | RAIL PLATE INSERTER - A workhead assembly for use with a rail maintenance machine having a workhead assembly for use with a rail maintenance machine having a rail lifter and configured for movement relative to a railroad track having a pair of rails, the workhead assembly constructed and arranged for positioning a tie plate predisposed on a rail tie, including a workhead body connected to the machine; a centering apparatus on the body constructed and arranged for centering the workhead over the tie; a squaring apparatus on the body constructed and arranged for squaring the tie plate on the rail tie; and a pusher assembly on the body for positioning the tie plate under a selected one of the rails being lifted by the rail lifter, and including at least one plate engaging finger constructed and arranged for engaging the tie plate. | 03-31-2011 |
| 20110100248 | TIE PLATE SINGULARIZATION DEVICE - A device for sorting railroad tie plates comprises hopper, singulator and chute assemblies mounted to a main frame capable of rolling movement along a railroad track. The device receives a plurality of tie plates from an upstream supply, e.g., a railroad gondola, and deposits the tie plates on the hopper assembly positioned above the singulator. Upon discharge from the hopper the tie plates are directed onto a central hub for guidance into a rotating track within the housing. The track width is selected so that the field and gage ends transverse the track upon the tie plates falling flat onto the track. Structure projects into the track to tip over the tie plates to a flat position during track rotation. Rotation of the track moves the tie plates towards a baffled opening for discharge from the opening. A chute assembly receives the tie plates and maintains the tie plate orientation for delivery to downstream devices, such as a conveyor belt. Upon rolling movement of the main frame tie plates are sequentially deposited along the course of the railroad track to enhance railroad track maintenance. | 05-05-2011 |
| 20110113981 | Sensor and Apparatus for Positioning Railroad Tie Plates Along a Railroad Track and Method - A method for positioning a replacement railroad tie plate along a railroad, comprising the steps of positioning a carrier vehicle on a railroad track, positioning a feed conveyor on the railroad track for movement with the carrier vehicle, moving a sensor assembly in a longitudinal direction of the feed conveyor and relative to a release point a first distance based upon a second distance between two adjacent ties, moving the carrier vehicle and the feed conveyor along the railroad track, detecting an in-service tie plate with the sensor assembly and, actuating a gate assembly upon the detection of the in-service tie plate. | 05-19-2011 |
| 20110146527 | System and method for railroad track tie plate orientation - A machine for automatically orienting railroad tie plates includes a sensing region having at least one optical sensor adapted to sense a physical feature of a tie plate. An electronic controller is connected to the optical sensor and is disposed to receive a sensor signal indicative of the physical feature of the tie plate when the tie plate is in the sensing region. The electronic controller further determines an orientation of the tie plate based on the sensor signal, compares it to one or more predetermined or possible orientations, and provides a command to at least one actuator adapted to perform at least one tie plate orientation operation to change the orientation of the tie plate based on the comparison of the orientation of the plate with the predetermined orientation. | 06-23-2011 |
| 20110239893 | RAILROAD TIE PLATE HANDLING MACHINE - A tie plate handling device for use in connection with removing and replacing railroad tie plates from a track during a rail change-out process. The tie plate handling device provides operator lift assistance and certain embodiments provide for a fully automated lift and movement of railroad tie plates. The tie plate handling device comprises a lifting arm, an engaging unit for securely coupling with a tie plate and a control unit for operating the same. Methods for using the tie plate handling device in conjunction with the rail change-out process are also described. | 10-06-2011 |
| 20120204752 | RAILROAD TIE PLATE APPARATUS AND METHOD - A cleated belt conveyor is positioned atop a frame connected to a hi-rail truck. The cleated belt conveyor is operably connected to a railroad engagement wheel positioned under the frame to coordinate movement of the cleated belt conveyor relative to the railroad engagement wheel. A sliding member can be positioned at the top, or infeed end, of the cleated belt conveyor for receiving railroad tie plates from an infeed conveyor. One or more sets of rollers can be positioned at the bottom of the cleated belt conveyor for distributing the tie plates near a rail in a desired orientation. | 08-16-2012 |
| 20120204753 | RAIL PLATE INSERTER - A preferred embodiment is directed to a finger for use in a rail plate inserter machine workhead and for positioning a rail plate predisposed on a rail tie under a rail, having a planar body having an upper arm with a hook-shaped end and including an opening for accommodating a spring, the end being configured for being contacted by a bar operatively associated with a finger lift assembly; a lower arm having a depending tip; and a middle portion joining the upper and lower arms to define an obtuse angle. | 08-16-2012 |
| 20140251175 | RAILROAD TIE PLATE DISPENSER - A railroad tie plate dispenser includes a feed chute having a top portion for receiving a stack of railroad tie plates and a push tab at a bottom portion of the feed chute for stripping railroad tie plates from the feed chute through an opening in the feed chute to dispense railroad tie plates from a front side of the feed chute. | 09-11-2014 |
| 20160130767 | METHOD FOR GUIDING A DEVICE FOR INSERTING ELEMENTS INTO THE GROUND FOR THE BUILDING OF A STRUCTURE; INSERTION DEVICE AND ASSOCIATED VEHICLE - A method includes: taking a topographical survey of a plurality of geographical points near a structure to be built, the position of each point being determined in an absolute frame of reference XYZ; installing a plurality of reflectors, each reflector being placed at a geographical point of the topographical survey; measuring distances between reflectors and optical devices, using at least three optical devices fixed on a moving arm of an insertion device that bears an element to be inserted; computing, by trilateration, the absolute position of the arm of the insertion device from the measured distances and from the known position of each optical reflector; and moving the arm of the insertion device based on the computed absolute position, so as to bring the element to be inserted into a predetermined implantation position. | 05-12-2016 |
