Description
MODULAR SUPPORT STRUCTURE
OBJECT
The present invention relates, in general, to a provisional modular support structure of a railway line in service during the execution of works underneath the rails of the railway line itself.
STATE OF THE ART
It is known in the state of the art that removal of a level crossing in a railway line in service requires leaving the rails of the railway line without a support base.
Whilst the jacking works of a concrete box, for example, are performed, there is an infrastructure to support the rails of the railway line in service.
The support infrastructure in the form of a set of shoring or support rails parallel to the rails of the railway track disposed detachably along the outer side of the rails and fastened by brackets to the same rails, being braced by cross-beams, disposed between the sleepers of the rails of the railway line, which solidly joins both shafts of shoring rails, supporting at the same time the load of the circulating rail vehicles.
Sometimes it is necessary to position wooden chocks between the cross-supports and track sleepers, that serve to guarantee the correct level or cant of the rails of the railway line when the box is being jacked.
The shoring rails rest on the ends of the cross-beams and by means of a mechanical joining unit joining the ends of the cross-beams to the shoring rails.
Therefore, the assembly and dismantling works of the provisional support infrastructure of the rails of the railway line are laborious and requires the traffic to be cut for considerable times, requiring a reduction in speed of the rail vehicles that circulate in the works execution area, creating an important interference in normal rail traffic.
SUMMARY
The present invention seeks to resolve or reduce one or more of the drawbacks stated above via a detachable modular support structure for the rails of a railway line in service during the execution of works underneath the rails as claimed in the claims.
The modular support structure provides resistance, solidity and stability to the stretch of railway track wherein works are performed underneath the track;
guaranteeing the track width and the inclination of the rails with respect to the running surface and allows easy detachment without the need to move the rails.

The regulating device 18 is disposed, initially, between the sleepers 15 of the rails 12 in flat position; i.e. the second and third adjustable pressure cylinders 33, 34 are disposed parallel to the first adjustable pressure cylinder 31; then the distal ends, with respect to longitudinal axis of the railway line, of the second and third adjustable pressure cylinders 33, 34 are vertically raised until reaching the working position; to be hooked to the corresponding upper bores 371 of the inner strips 37 of the shoring beams 161, 162 by means of the mechanical fixing elements.
The first, second and third adjustable pressure cylinders 32, 33, 34 are configured as adjustable tighteners to tighten and support the shoring beams 16, 161, 162 and, consequently, the rails 12 are fixed and the running surface of the same rails 12 is maintained; by modifying the length of each adjustable pressure cylinder 32, 33, 34.
Therefore, the regulating device 18 is a triangulated device joined in the form of triangles, subjected to traction and compression forces so that it has height regulation
In working position of the modular support structure 11, the second and third adjustable pressure cylinders 33, 34 form, respectively, with the first adjustable pressure cylinder 32 an acute angle oriented perpendicular to the running surface, both acute angles not having to be fowled the same.
The lower strip 37 comprises at least one upper bore 371 and a lower bore 372 misaligned according to a vertical axis parallel to the vertical side of the lower strip 37.

The regulating device 18 is disposed, initially, between the sleepers 15 of the rails 12 in flat position; i.e. the second and third adjustable pressure cylinders 33, 34 are disposed parallel to the first adjustable pressure cylinder 31; then the distal ends, with respect to longitudinal axis of the railway line, of the second and third adjustable pressure cylinders 33, 34 are vertically raised until reaching the working position; to be hooked to the corresponding upper bores 371 of the inner strips 37 of the shoring beams 161, 162 by means of the mechanical fixing elements.

Therefore, the regulating device 18 is a triangulated device joined in the form of triangles, subjected to traction and compression forces so that it has height regulation
6 and locking mechanisms of the rails 12 with respect to the support base of the same rails 12.
As is shown in figure 3, the first, second and third adjustable pressure cylinders 32, 33, 34 are formed by tightening elements threaded to threaded sleeves so that the tightening elements are displaceable between a maximum and minimum length of the same threaded sleeve of the first, second and third adjustable pressure cylinders 32, 33, 34, respectively, and fixed by their ends to the shoring beams 161, 162 and anchoring projection 35 to regulate the height of the running surface of the rails 12.

The longitudinal displacement of each pressure cylinder 32, 33, 34 is transmitted to the shoring beams 161, 162 through the ends of the pressure cylinder 32, 33, 34, respectively, to maintain a constant tension which compensates for changes in length due to the deflection exerted by the rail vehicles which circulate along the stretch of rails 12 where works are being performed underneath the track.
In relation now with figure I, the shoring beams 16 are disposed respectively along the outer side of the rails 12 and are oriented perpendicular to the running surface towards the support base of the rails 12.
The cross-beams 14 support the sleepers 15 in working or service position and .. mechanically cooperate with the regulating device 18 to maintain the track width.
The modulating support structure Ii comprises a plurality of cross-beams 14 which are disposed between the sleepers 15 of the rails 12 of the railway line and underneath the same rails 12 in working position; in orientation perpendicular to the axis of the railway line and in the direction of the jacked box 13, so that they transmit the loads of the rolling stock towards the plurality of shoring beams 16 disposed parallel to the rails 12.

The longitudinal displacement of each pressure cylinder 32, 33, 34 is transmitted to the shoring beams 161, 162 through the ends of the pressure cylinder 32, 33, 34, respectively, to maintain a constant tension which compensates for changes in length due to the deflection exerted by the rail vehicles which circulate along the stretch of rails 12 where works are being performed underneath the track.
In relation now with figure I, the shoring beams 16 are disposed respectively along the outer side of the rails 12 and are oriented perpendicular to the running surface towards the support base of the rails 12.

In relation now with the figures 2A, 2B and 4, the cross-beam 14 has a resistant cross-section composed of a H-profile; comprising flanges mechanically joined to a web.
The cross-beam 14 has in the opposite ends of the web at least one oblong bore horizontally elongated towards a central vertical axis of the cross-beam 14, to facilitate
7 the mechanical joining and securing between the cross-beam 14 and the shoring beams 16, 161, 162.
The shoring beams 16 comprise a plurality of seat sockets 22 regularly distributed throughout the web to join the pair of shoring beams 16 longitudinally through the cross-beams 14.
The shoring beams 16 and the cross-beams 14 mechanically cooperate to fix the track width, maintaining the rails 12 and the sleepers 15 in the working position whilst works are being performed underneath the rails 12.
Each end of a cross-beam 14 is introduced and rests in a seat socket 22 of a shoring beam 16; being detachably mechanically fixed by means of the introduction of mechanical fixing elements 23 of mechanical joining within the corresponding oblong bores 41.
Obviously, if the shoring beams 16 comprise a high number of seat sockets 22, a high number of cross-beams 14 can be housed and, therefore, the support provided by the assembled support structure 11 shall be greater and, consequently, there will be greater immobilization provided to the rails 12 of the railway line.
