Description
- This invention claims the benefit of U.S. Provisional Patent Application No. 61/677,410 filed on Jul. 30, 2012 and U.S. Provisional Patent Application No. 61/730,023 filed on Nov. 26, 2012, which are both hereby incorporated by reference in their entirety.
- 1. Field of the Invention
- The embodiments of the invention relate to railway devices, and more particularly, to a by-gear railway transport. Although embodiments of the invention are suitable for a wide scope of applications, it is particularly suitable for railway transport of equipment in which the equipment can be mounted and dismounted on the railway line as well as enable both the equipment and the railway transport to get on the railroad tracks and get off the railroad tracks.
- 2. Discussion of the Related Art
- In general, equipment for constructing or maintaining a rail way or the rail line of a railroad is transported to a job site by either using the rail line itself or a road adjacent to the rail way. However, some rail ways go through areas where there is no road access, much less a road. Thus, use of the rail line itself in a rail way is the most assured way of getting construction/maintenance equipment to a desired site along a rail way. There are generally two types of transportation techniques for moving construction/maintenance equipment along a rail way, either the maintenance/construction equipment is loaded on a railcar or by-rail wheels are on the maintenance/construction equipment.
- The use of railcars blocks the rail line during the work if the railcars are left on the work site. Otherwise, the removal and arrival of the railcars for the maintenance/construction equipment has to be scheduled. Moving empty rail cars after drop-off or before pick-up of maintenance/construction equipment is time consuming and expensive.
- Retrofitting hy-rail wheels to maintenance/construction equipment can be expensive. Such retrofitting requires integrating the hy-rail wheels into the equipment so as permanently attach the hy-rail wheels. Typically, all of the hy-rail wheels are free wheels and the hy-railed equipment is pulled by a railway locomotive. Further, retrofitting drive hy-rail wheels may require major structural modifications to the equipment and reduce the functionality or versatility of the equipment. For example, the equipment has to stay on the railroad track at a worksite. In another example, the equipment is dependent on a railway engine to move up and down the railroad tracks during the work at the worksite.
- Accordingly, embodiments of the invention are directed to a hy-gear railway transport that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
- An object of embodiments of the invention is to provide a hy-gear railway transport having drive hy-gear that is separable from the equipment to be transported.
- Another object of embodiments of the invention is to provide a hy-gear drive railway transport in which the drive hy-gear can be attached without substantial structural modifications of the equipment to be transported.
- Another object of embodiments of the invention is to provide hy-gear drive railway transport in which the drive hy-gear can be moved off and on the railway line.

As shown inFIG. 16 , therailway wheels gear 100 are below theblade assembly 200 of the trackedexcavator 201 between the blade and thetracks 205 of the trackedexcavator 201. Therailway wheels gear 100 positioned to be lower than thetracks 205 of the trackedexcavator 201. Thus, the drive hy-gear 100 under theblade assembly 200 keeps the front of the trackedexcavator 201 off of the railroad tracks 500. - The
loop 215 on the drive hy-gear 100 at the front of the frame is used with theboom 207 of the trackedexcavator 201 to position the drive hy-gear 100 off of therailroad tracks 500 or to position the drive hy-gear 100 on the railroad tracks 500. To mount the drive hy-gear 100, theboom 207 of the trackedexcavator 201 is first used to lift up the front of the trackedexcavator 201 and then the trackedexcavator 201 tracks to position theblade assembly 200 over drive hy-gear 100. Then, theboom 207 is used to lower theblade assembly 200 onto the drive hy-gear 100. Thus, the drive hy-gear positioned under theblade 200 suspends the front of the trackedexcavator 201 over the railroad tracks 500. Then, the drive hoses and brake hoses of the drive hy-gear 100 are hooked up to the trackedexcavator 201. The drive hy-gear 100 together with one of the ride-on hy-gear and drop-down hy-gear in ride position enables the trackedexcavator 201 to traverse the railway tracks 500 with hydraulic power from theexcavator 201. - It will be apparent to those skilled in the art that various modifications and variations can be made in the drive hy-gear and ride hy-gear railway devices of embodiments of the invention without departing from the spirit or scope of the invention.
