20080216702 | Model railroad track scrubbing car - The invention is a model railroad track scrubbing car with rollers set at a scrub angle of about 30° to scrubs the tops and sides of the track rails. The rollers freely rotate about fixed axels under the chassis of the weighted car. Each roller is preferably a conventional paint roller with an inner sleeve and an outer tubular roll made of an absorbent, compressible, resilient foam material. The active working surfaces of each roller compress against, frictionally engage and deform around the tops and sides of the rails. The scrub angle and rollers provide across-the-rail scrubbing action and possibly along-the-rail scrubbing action. The circumferential working areas of the rollers are wider than the width of their associated track rails. The scrub angle and height of the roller axels above the track rails are adjustable to set the amount of roller compression and scrubbing action against the track rails. | 09-11-2008 |
20100258026 | DEVICE ATTACHED TO GUIDED VEHICLE TO REMOVE OBSTACLES ON GUIDEWAY - The object is to provide an obstacle-removing device for a removing obstacles on guideway, which is simple in configuration, low in manufacturing cost, and can remove the obstacles steadily and effectively, and of which the brushes for sweeping the running surface can be retracted easily when the device is in the rear side of traveling direction of the vehicle. The device comprises; a vertical frame positioned to the leading end in traveling direction of the vehicle, and a lifting/lowering device attached to the said vertical frame to lift and lower a brush holder attached to a vertically movable member which can be lifted and lowered by the lifting/lowering device, the brush holder having brushes for removing obstacles on the guideway; wherein the brush holder is pivotally attached to the vertically movable member such that the brush holder is tilting forward when the brushes held by the brush holder contact the running surface to perform obstacle-removing operation. | 10-14-2010 |
20120222580 | RAILROAD TRACK CLEANING ASSEMBLIES AND APPARATUS - Railroad track cleaning assemblies and apparatus are described. An example railroad track cleaning assembly includes a movable carriage movably coupled to a frame to which a plurality of wheels are operably coupled to enable the frame to move on railroad tracks. Additionally, the railroad track assembly includes a shaft rotatably coupled to the movably carriage to receive one or more brushes that are to be rotated and engage one of the railroad tracks and a spring assembly coupled to the movable carriage and to the frame to bias, via the movable carriage, the one or more brushes into engagement with the one of the railroad tracks. | 09-06-2012 |
20130081552 | Device and Method for Cleaning Model Train Track - A model train track rail cleaning device includes a base, a cleaning pad mounted to the bottom of the base and a grip body coupled with the top of the base. The cleaning pad has a set of grooves positioned parallel to one another and spaced to receive track rails when the pad is in a first orientation. The cleaning pad also has a second set of grooves positioned parallel to one another and perpendicular to the first set. The second set of grooves is spaced to receive track rails when the pad is in a second orientation. Preferably, the first set of grooves is spaced to receive the rails on model track of a first size and the second set of grooves is spaced to receive the rails on model track of a second size. The cleaning device is pushed and pulled across the rails to clean them. | 04-04-2013 |
20150053109 | PNEUMATIC TRACTION ENHANCER FOR RAILCAR MOVER - A railcar mover is provided that is configured for use on a railroad track and has a frame, a plurality of traction wheels, and a traction enhancing system. Included in the traction enhancing system is an air nozzle associated with at least one of the traction wheels, mounted directly or indirectly relative to the frame so that an outlet of the air nozzle is directed at a corresponding rail of the railroad track for emitting high pressure air for removing at least one of unwanted debris and moisture. In addition, a scraper blade is associated with the nozzle and mounted relative to the nozzle so that the scraper blade contacts debris on the track before the high pressure air, in a direction of travel of the mover. | 02-26-2015 |
20150345089 | MOUNTING DEVICE FOR A DEBRIS DEFLECTOR - Methods and systems for a mounting device for mounting debris deflector to transportation vehicles such as light rail which helps to position the deflector at the front or rear end of vehicles are disclosed. The mounting device is located between the deflector and transportation vehicle and includes a longitudinal member having a proximal end and a distal end, a first base plate rigidly connected to the proximal end of the longitudinal member, and a second base plate rigidly connected to the distal end of the longitudinal member. Further, the first base plate may be connected to understructure of the transportation vehicle, and the second base plate may be connected to the debris deflector. | 12-03-2015 |
20160060835 | SNOW REMOVAL BRUSH, VEHICLE, COMBINATION VEHICLE, AND TRACK TRANSPORTATION SYSTEM - A snow removal brush includes a brush rotary shaft that is disposed on each of opposite lateral surfaces of a vehicle body traveling along a track and in a vehicle width direction of the vehicle body and is supported by the vehicle body to be rotatable about an axis extending in a direction intersecting a track surface of the track, and a brush part that protrudes from an outer circumferential surface of the brush rotary shaft to a radial outer side. The brush part is formed to come into contact with trolley wires provided for the track and supplying electricity to the vehicle body. | 03-03-2016 |
20160069033 | SNOW REMOVAL DEVICE, VEHICLE, AND TRACK TRANSPORTATION SYSTEM - A snow removal device includes: a brush rotary shaft that is mounted on a vehicle body traveling along a track and in front of a running wheel of the vehicle body and that is rotated in a direction opposite to the rotation direction of the running wheel; a travel brush part that protrudes radially outward from an outer circumferential surface of the brush rotary shaft and comes into contact with a runway of the track with which the running wheel is in contact; and a brush pressing part that presses the travel brush part toward the runway. The travel brush part is provided in a spiral region formed on the outer circumferential surface of the brush rotary shaft in a spiral manner extending toward an axis direction in which the axis extends as going toward a circumferential direction of the brush rotary shaft. | 03-10-2016 |
