Description

Continuous track renewal system in sections complete armed.

Object of the invention

The present invention, as expressed in the stated in this report, refers to a procedure designed to perform the replacement of constituent obsolete elements of the railway superstructure of a railway track: ballast, sleepers and rails, processing sequentially and continuously complete sections armed, that is, segments of flanged rails to their corresponding sleepers through the appropriate elements of subjection.

Background of the invention

The road, as a depreciable asset, requires a regeneration at the end of its useful life, since it is not profitable prolong investments in maintenance activities.

The classic methods of track renewal using heavy machinery involve considerable disruption to the train service: deviations in the meshes to locate the job cuts, temporary speed limitations, etc.

To mitigate such inconveniences, and make profitable the road rehabilitation operations, they are gone developing over time means to reduce the involvement in rail traffic, inserting jobs planned in the maintenance bands, and increase the productivity, optimizing the time taken to perform the extraction and laying activities, through a process systematic, sequential, modular and continuous.

In this sense, the so-called Fast renewal trains, such as patent objects CH686144, US5092247, EP0771909, AT316614, EP0019984, FR2419998 or the EP0168101, among others. Except for differences inherent to the object of protection advocated in each, converge on the philosophy of Work modularly in a linear and continuous sequence. How can see in figure 1, it is impossible to lift and remove a set of used rails and sleepers (6) simultaneously to the laying of another new one (10) of elements also coupled, arranged both horizontally, by bending sequential thereof on transverse axes to the track axis, because they hinder (16) each other. The mentioned patents solve such inconvenience by processing lanes and sleepers by separate: disarming, segregating, extracting and directing into space of collection for disposal the old, of a part, and provisioning, positioning and tending the new ones to later assemble them by the corresponding fasteners.

On the other hand are the RU2303095 patent and SU1379394, both converge in the processing of complete sets assembled To solve the problem described above, shown in figure 1, they manifest the collection on foot of work of the new sets down with the sleepers in position vertical and positioned on an articulated set of vehicles suitable for that purpose. In a first operation they extract the section old man raising his head by means of a gantry crane located in a Vehicles end. Then the vehicles in the sense of renovation, so that the section old track is gradually turned by means of some devices established for this purpose, placing their sleepers upright and gradually deposited in such a way along the vehicles. In a second operation, inverse to the previous one, deposit the new section on the bed. In both operations the rail-sleeper assemblies remain fixed with respect to the longitudinal axis of the track, its displacements being relating to vehicles.

Description of the invention

The solution to the object stated above is provided in accordance with the present invention by inserting a central process structure (1), see figure 2, in a set articulated mobile (2). The complete unit will have translation uninterrupted (3) along the longitudinal axis of track during renovation operations to provide continuity to such sequence of activities.

The main installation (1) will be in charge to extract obsolete elements: ballast and grid of rails and sleepers (6), of the track bed (11) and lead them to their destination transport locations, (14) and (15), as well as the transfer of the new armed sections (10) from the point of gathering (12) to its planned location in the infrastructure railway Longitudinal displacements, according to the axis of track, of the rail-naughty blocks will be, except exception in specific phases such as the beginning and / or end of the process, relative to the articulated mobile assembly, keeping the position fixed absolute of them with respect to the land.

In order to perform the maneuvers listed, the main module (1) will be equipped in its front tester, according to the direction of advancement of the appropriate devices for the deguarnecido and extraction of the ballast (4), the hoisting (5) of the original grid of sleepers and rails (6) and the loosening of their fasteners On the other hand, you will have the necessary mechanisms to facilitate uninterrupted, simultaneous and free of obstacles the transfer inside of both armed packages of Rails and sleepers. The set (6), after lifting, will be elevated, displaced (7) and dejected through the mechanisms mentioned, arranging its sleepers in an upright position (8) to leave a gap (9) where the new section (10) of lanes can run and sleepers towards their point of laying on the bed of the track (11). The dejection of the old section (6) can be done in two ways different: previously separating it into two parallel rows, each containing a lane and, alternatively, a crossbar of every two, mode represented in figure 2, or by moving laterally and depressing the complete grid, method no represented. The choice of one procedure or another is subject to design and constructive conformation of the module (1), as well as its bearing capacity The new section (10) will be transferred from your original position of collection (12) to the bed of track (11), keeping constant horizontal alignment of its sleepers, by successive changes in elevation caused by push-ups on it several axes transverse to the track axis and parallel to each other. The new set fasteners (10) will not have the nominal tightening so that it can adjust to the railway track during the transport and site maneuvers on track. Once the corresponding cross section of the old grid (6) beech crossed longitudinally, according to the track axis, the area of the hollow space (9) through which the new (10) descends, will be replaced to its original orientation and alignment (13) heading to the point withdrawal (14). In the same way the old ballast, after its extraction (4), will be conducted through the appropriate mechanisms to a point of screening or transportation to disposal (15). Dimensions of the transfer zone of both armed sections, the angles and bending radii, as well as the pitch of the blasting propeller (s) they will be such that the tensions to which the rails are subjected during your transfer do not exceed your elastic limit.

Preferred Embodiment of the Invention

According to the idea defined as the object of the patent, the preferred embodiment thereof consists in the provision of an articulated convoy of modular design, whose Abbreviated schematic representation is reproduced in Figure 3. In it draws a simplified conformation of the structure process center (1) interspersed in the articulated convoy (2); East It is provided with continuous and uninterrupted translation (3) during the sequence of scheduled activities thanks to the element tractor (17).

The main module (1) is erected by a self-supporting structure (18) supported by appropriate pillars (19) in convenient translation mechanisms, well rolling exclusively railway (20) or alternative rolling (21) between the railway and other not linked to the rail: movable on the bed of the track (11), like a caterpillar or similar. The aforementioned central installation (1), given its multifunctional configuration to provide a development sequential and concatenated operations, will perform on the one hand the removal of the old ballast (4) using the devices suitable, which can be of any kind of construction known (e.g., chain or worm). This old ballast will be taken to its point of treatment or withdrawal through relevant transfer mechanisms (15), such as tapes continuous conveyors, buckets or endless type pipes. Figure 3 shows the routing of this ballast towards Receiver modules for waste disposal (22), but also can be distributed to a screening module, not shown, for reuse

Once the extraction process of the old ballast, the central module (1) will activate the corresponding mechanisms for lifting (5) the old grid (6) and loosen it in the necessary proportion of its fasteners, raising it gradually by means of a chain or continuous band, inclined and attached to the self-supporting structure (18) by means of the supports suitable, up to the ideal level to proceed with its displacement transverse and abatement (8) which, as described above, it can be done in two different ways: by previously separating it into two parallel rows, each containing a lane and, alternatively, one naughty of every two, or shifting laterally and knocking down the complete grid. In both cases the relative translation of the folded set of rails and sleepers with respect to the main module (1) it can be implemented using as bearing element, either to the rails themselves sliding to along some low friction guides, or some solidarity claws to a continuous conveyor belt / s that suspend the set at the right points. In each case, both the guides and the / s Conveyor belt / s must be fastened longitudinally to the self-supporting structure (18).

Once the set (6) is knocked down, it will remain made a hole where the new section can run assembly of rails and sleepers (10) towards laying on the bed of the track (11). Previously the new grid, whose fasteners will not have the nominal tightening so that it can be adjusted to the railway track during its transport and the maneuvers of location on track, as referred to above, must move from the transport and storage modules (12) to the setpoint via devices similar to those described to raise the old assembly (6). The same design constructive will have the mechanisms arranged to descend the new block (10) from the established level until its deposit in the track platform (11). In all traffic from your position original of collection (12) until its deposit in the bed of track (11), the new section (10) will be transferred keeping constant the horizontal alignment of its sleepers, through successive changes of dimension produced by bending it on several axes transversal to the track axis and parallel to each other.

As described above, once the corresponding cross section of the old section (6) has crossed longitudinally, according to the track axis, the area of the hollow space (9) through which the new (10) descends, will be replaced to its original orientation and alignment (13) heading to the module from transport to withdrawal (14). The covers arranged in the modules (12) and (14) for loading rails and sleepers will be equipped with motorized endless chain or band type mechanisms, to provide the longitudinal displacement of the materials provisioned Ultimately, they join the convoy articulated (2) modules for transport and ballast collection new (23), in order to give the necessary contribution of this aggregate to the support and wrapping of the new rail grid and sleepers (10).

The proportions and scale of the figures Attached are not real. The dimensions of the main module of process (1), particularly in the transfer zone of both armed sections, the angles and radii of flexion thereof, as well as the passage of the blasting propeller / s will be such that the tensions to which the rails are subjected during their transfer Do not exceed your elastic limit.
