Description
1~19(1~4 ,~
This invention relates to a device suitable for use in raising railway rails.
According to the invention there is provided a device for use in raising railway rails from their foundation, which device comprises:
a trolley constructed to run on the rails of a railway track;
a support structure carried by the trolley positioned to be between the rails of the track;
rail-gripping means carried by the trolley for engaging at least one of the rails; and operating means capable of lowering the support structure onto the foundation of the railway track and, while the rail-gripping means is out of engagement with the rail or rails, raising the trolley so that the latter can be turned about a vertical axis and, while the rail~
gripping means is in engagement with at least one of the rails, raising the trolley so that the trolley is supported by the support structure and the at least one rail is raised from the foundation with the trolley.
Preferably, the device has a pair of said rail -gripping means, each arranged onjjthe trolley for engagement with a respective one of the rails.
The support structure is confined, when lowered, to the area between the rails, and may stand on one or more ;ailway sleepers, on ballast between sleepers or on a continuous slab extending along the railway track in order to support the trolley when the latter is in its raised position.
An example according to the invention is described below with reference to the accompanying drawings, in which:-Figure 1 shows a rear view of a device suitable for use in raising railway rails, standing on two rails of a railway track which lie on railway sleepers, and B qF

1 a further front wheel and a further rear wheel 2A which run on the other rail 3A of the railway track. The rails are laid across concrete railway sleepers 4 on which lie pads (not shown) of electrically insulating material, upon which the rails lie. Grippers 10 and 1OA actuated by hydraulically operated piston-and-cylin-der devices can grip the webs of the rails 3 and 3A and the grippers 10 are carried on a structure 34 which is pivotally connected to the lower ends of arms 22 and 23, the upper ends of which are pivotally connected to the chassis 24 of the trolley. The four pivot axes are all parallel to one another and they intersect an imag-inary plane, which is perpendicular to all of them, at four points 25 to 28 which lie at the corners of a parallelogram, as shown in Figure 2, in which the parts 34 and 22 to 24 are also diagrammatically illustrated.
By swinging the structure 34 upwardly and to the right, the grippers 10 are raised without their orientation being changed. In this way one can cater for rails of different height. The structure 34 can be swung upward-ly to the right, and subsequently in the reverse direc-tion, by a piston-and-cylinder device (not shown) of which the piston rod is pivotally connected to the structure 34, whereas the cylinder is pivotally connec-ted to the chassis 24. There is a correspondin~ arrange-.ent on th~ other side of the trolley.
In addition to all the features described in _ U ~- Spct~lc~ o- 20~,7~
, including parts for driving rail clips parallel to the rails into and/or out of rail-fastening positions on the railway track, the illustrated device has a support structure 40 which, when the trolley is runninO along the railway track, is in a raised position, as shown in Figure 1. The support structure 40 comprises a circular plate 41 and a vertic-al column 42 projecting upwardly from its centre. By ahydraulically operzted piston-and-cylinder device, not shown, the support structure can be lowered so that the 1~90~4

The rails are laid across concrete railway sleepers 4 on which lie pads (not shown) of electrically insulating material, upon which the rails lie.

The four pivot axes are all parallel to one another and they intersect an imag-inary plane, which is perpendicular to all of them, at four points 25 to 28 which lie at the corners of a parallelogram, as shown in Figure 2, in which the parts 34 and 22 to 24 are also diagrammatically illustrated.

The support structure 40 comprises a circular plate 41 and a vertic-al column 42 projecting upwardly from its centre.

1 ?late 41 stands centrally on one of the sleepers and t then, with the grippers 10 and 10A gripping the rails, the same piston-and-cylinder device can be operated to lift the trolley, and with it the rails, so that the .
5 rzils no longer lie on the sleepers, as shown in Figure 2, the trolley and part of the weight of the rails being supported by the support structure 40. Whilst the rai's are raised, the above-mentioned pads can be removed from under them and, if desired, replaced by new ones.
When the trolley has been raised as described above whilst the grippers 10 and 1OA are not gripping the rails, and the structures 34 are in their raised positions, the trolley can be turned through 90 about the vertical axis of the column 42, such is the connec- ¦
tion between the column 42 and the trolley, so that the trolley can run off the railway track on to a short cross-line, for example whilst a train passes on the railway track. The trolley can also be turned through 180 so that it can then travel in the opposite direc-20 tion without the operator using reverse gear, if the trolley has a reverse gear.
