Rail stabilizer for rail tie replacement |
| 摘要 |
A stabilizer is disclosed for use in stabilizing and maintaining the spacing between a pair of railway rails during rail tie replacement. The stabilizer comprises a rod having a length and a pair of ends. A pair of rail clamps is carried by the rod, and each clamp is configured to engage one of the rails and secure the rail relative to the rod. An expanding member is carried by the rod and configured to selectively expand along the length of the rod between its ends to engage a structure proximal to the rails, wherein, upon engagement of the rails by the rail clamps and the expanding member with the structure, the rails are maintained in substantially fixed relationship to each other and to the structure, but are free to be moved vertically relative to the structure. |

1. A stabilizer for use in stabilizing and maintaining the spacing between a pair of railway rails during rail tie replacement, the stabilizer comprising:
a rod having a length and a pair of ends; a pair of rail clamps carried by the rod, each clamp configured to engage one of the rails and secure the rail relative to the rod; and an expanding member carried by the rod and configured to selectively expand along the length of the rod to engage a pair of spaced-apart support beams supporting the rails, wherein, upon engagement of the rails by the rail clamps and the expanding member with the pair of support beams, the rails are maintained in substantially fixed relationship to each other and maintained in alignment with the pair of support beams, but are free to be moved vertically relative to the pair of support beams. |
