Description

The invention relates to a device for the expansion of a rail track tracks or track rails formed for rail vehicles and is also directed to a method for removing a track formed of track fields or track yokes track, especially a track laid in a ballast track.

In the rehabilitation or dismantling of old track bodies, not only the rails but also the most laid in the ballast sleepers are to be expanded, the expansion often takes place in whole track fields, ie over a comparatively long length extending track sections, previously from the old track were separated, so that the track field thus dissolved from the track network with its two rails and the still firmly mounted sleepers can be lifted out of the ballast bed and transported away.

In the known devices and methods for removing an old track lifting the track fields is usually done by lifting cranes that drive on a neighboring track to the track to be removed and store the excavated track gap on a usually arranged between two cranes transport car. However, this has the disadvantage that hereby an old track can only be removed and removed track lengths can be removed if, in addition to the old track to be rebuilt or rehabilitated, a second track is available on which the construction vehicles can roll. In addition, the known technique has the disadvantage that comparatively complicated maneuvering operations are required as soon as the transport wagon running between two cranes is loaded to its capacity limit and must be exchanged for another wagon.

The object of the invention is to provide an apparatus and a method for the development of a track formed from track sills for rail vehicles, which also single-track tracks can be developed in one operation in an advantageous manner and thus the removal of the developed track fields without complicated maneuvering is possible ,

To achieve this object, the device according to the invention consists essentially of a subdivided into at least two sections, can be arranged on the track to be constructed support structure which is supported by support posts on the track bed, with one of the first, rear section associated lifting device for a track field, one between the two Sections movable transport device and arranged at the second section loading station, wherein the support structure, at least in the region of the second section of a trackable on the track rail vehicle, in particular a transport car, is traversable, With such a device according to the invention, the inventive method can be carried out in an advantageous manner be characterized in that a consisting of at least two sections support structure is arranged above the track to be removed and supported by support posts that they from at least a rail vehicle on the track, in particular a transport wagon, in the front section is traversed, with a located in the rear section track dug by means of a support structure arranged lifting device excavated from the track bed and by means of a transportable along the support structure transport to one of the second, front section arranged loading station and loaded onto a rail vehicle arranged there.

According to the invention, therefore, the old track to be excavated is used even for the removal of the track fields or rail sections and rail sleepers and transports the track field located at the end of the old track to be removed after it has been lifted out of the ballast bed by means of the lifting device from the rear track Section of the support structure in the front, second section, in which the old track is at least in tact so far in tact that it is a transport carriage for the developed track field or its components can be moved. This rail car can be arranged under the support structure in the region of the second, front section and the transport device with the hanging, straight track surface can be moved along the support structure from the first, rear section in the second, front section on the transport carriage under it where the track field is then deposited at the loading station on the transport wagon. The arrangement can be made so that the support structure in the region of its second, front section has a length corresponding to the length of at least two transport cars, in which case advantageously according to the method can be worked so that the stored on a transport wagon track tore in his individual components (sleepers and rails) is disassembled and the dissolved rails are then stored by means of the lifting and transporting device on the second, arranged in the front section of the transport wagon, while the rail sleepers remain on the first transport wagon.

In a particularly advantageous embodiment of the device according to the invention, the support structure has a third, to the second section before this subsequent section with a ballast loading station and subsequent to the first section a ballast removal device is provided, the above a conveyor for the track fields extending conveyor with the ballast loading station is connected. This advantageous structural design makes it possible to expand not only the individual track lengths of an old track from the ballast bed and arrange for removal on transport cars, but immediately following the expansion of the track lengths and the track ballast of the ballast bed and expand if necessary, further material from the footwall and to be transported away. According to the method, this is the like from gravel, solidified track substructure or the like. existing track bed expanded the expansion of a track field below using the ballast removal device and the removed material is transported by means arranged on the support structure conveyor to the disposed before the second section ballast loading station in the third section and there passed a transportable on the track transport car. According to the invention, it is possible to adapt and use the device described also for the removal of slab tracks. Due to the arrangement of the conveyor above the transport device, the space requirement of the entire system is very low, in particular in a direction transverse to the track longitudinal direction, which makes it possible in an advantageous manner to use the system and the method for removing a laid in a tunnel track. Moreover, the invention can also be used when, in addition to the track to be removed, a neighboring track runs on which the driving operation must be maintained during the dismantling work.

In an advantageous embodiment of the invention, the support posts of the support structure are height adjustable, which unevenness in the areas of the track bed, in which support the support posts can be easily compensated. The support posts are expediently arranged in pairs and are based on the right and left side of the track. In this case, the arrangement is preferably made so that at least part of the support posts is provided with a Schlittenfuß, over which they are supported on the footwall, especially on the ballast.

It is clearly advantageous that the device is movable along the track to be removed, so that the support structure according to the method can proceed along the track to be removed after the removal of one or more track fields and can be supported again. As a result, a track field located at the end of the old track to be removed can be successively excavated after the other and stored for transport on the transport carriage arranged in the second section for loading.

It when at least a portion of the support posts is preferably provided with hydraulic traction drives, whereby the inventive device by its own power, namely by means of the traction drives can proceed if there is no track under the supporting structure in the rear, first section, which must be removed.

It is advantageous if at least part of the support posts arranged in the second and / or third section can be supported on the rails of the track and are articulated to the support structure by means of a pivoting device with which they move laterally out of their supporting position on the rails in addition to a support structure undermined rail vehicle lying open position can be brought. The support of any case some support posts directly on the rails ensures a very high support stability even without under the support columns arranged floor plates or the like .. As long as the support posts are pivoted outwardly into the open position to allow the passage of a transport car, the transport device in the first section and the conveyor appropriately shut down, so that an overload of the construction is not to be provided because of insufficient support.

The sections of the support structures are preferably hinged together and thus allow to be easily adapted to the track layout. The transport device is preferably provided with a plurality of, in particular four hoists, in particular chain hoists forming the hoisting device, which are connected at the track area to be excavated at a plurality of points in order to reliably hold them. The hoists can be operated individually or in groups in order to carry out the excavation process optimally. The transport device is expedient along at least one arranged on the support structure, the first and second section bridging track rail movable and can thus together with a raised track field in the manner of a trolley from the first to the second section back and after transfer of the track field on the transport car again return.

Preferably, the conveyor is an endless conveyor, such as a chain scraper conveyor, a belt conveyor or the like., Which of the Gravel removal device excavated excavated, so in particular handed over the old track ballast and with which he is transported to the ballast loading station in the third section.

A particularly advantageous embodiment is obtained if at least one transport wagon with the device can be coupled and moved together with this, wherein in particular the one or more arranged in the second section transport wagons can be coupled and moved with the device. It is then unnecessary to move the wagons separately with a locomotive on the track when the device is displaced in the track longitudinal direction, after in the first section no track tracks to be removed are present. Rather, the device takes in this return operation, the wagons, which it engages portal-like, even with, with the relative position between the device and the wagons does not change and the wagons must therefore not be relocated after the walking process to their correct position for storing to get more track fields.

For a uniform loading of a transport wagon or the like with the excavated gravel material. it has proved to be useful if at least one transport car is movable relative to the device along the track, so that it can be moved slowly, for example by means of a shunting locomotive under the ballast, so that the material transported by the conveyor evenly distributed in the transport car.

In order to use the device according to the invention for the development of an old track, which is located in close proximity to a siding continued during finishing work siding is preferably at least on one side a lateral panel provided on the device, which prevents degraded gravel or the like. fall laterally next to the work area of the device on the siding and there may possibly lead to damage of a passing train. Such a cladding may for example be a continuous sheet metal cladding or from a stable wire mesh, which is close enough to the passage of larger bulkhead parts or the like. to prevent. The entire device is preferably remotely controllable, for example by means of a radio remote control.

The device 10 shown in its entirety in Fig. 1 consists essentially of a three sections 11, 12, 13 extending support structure 14 of steel profiles, which is supported by means of paired support posts 15, 16, 17 on the track bed 18. The entire device is located above a to be built old track 19, which towers over them like a portal. The first, positioned at the track end and thus rear section 11 (left in Fig. 1) defines a track removal field from which the track end defining track field 20 are excavated from the track bed 18, as can be seen in Fig. 1 at 21. For this purpose, a lifting device 22 in the form of four connectable to the track panel 20 chain hoists is provided on the support structure, which by means of a transport device 23 along the positioned above the old track support structure 14 on rails 24 is movable. In this case, the arrangement is such that the rails 24 extend over the first section 11 and the second section 12 up to the front, defined by the support post pair 17 end.

The second section 12 of the device 10 forms a loading station for the excavated in the first section track fields 20. For this purpose it is traversable by movable on the old track 19 transport wagons 25, wherein the length of the second section 12 is dimensioned so that two wagons completely space Find. An excavated by means of the lifting device 22 from the track bed 18 track area is raised so far that its underside above the frontal walls 26 of the transport cars 25 and transported along the rails from the first section 11 in the second section 12 and there above the first transport wagon a positioned, whereupon the lifting device 22 lowers the track field and thereby deposits on the first transport carriage 25a. It is possible in this way to load both transport wagons positioned in the second section with complete track fields up to the maximum loading height or transport capacity; Preferably, however, the first laid completely on the first transport car 25 track fields are broken down into their individual parts (rails and sleepers) and then passed the rails by means of the lifting and transporting device 22, 23 the second transport wagon, while the sleepers remain on the first transport wagon.

Above the transport device, an endless conveyor 27 with circulating conveyor belt is arranged between the rails, which is essentially arranged from an on the rear (in Fig. 1 left) end 28 of the first section 11 Aufgabeschütte 29 to a disposed in the third section 13 ballast loading station 30th extends. The feed chute 29 is associated with a ballast excavating device in the form of a Schrämbaggers 31, with the aid of which immediately following a track field and the track ballast and / or the track substructure ausgekoffert and handed over the Aufgabeschütte the conveyor 27. The thus-constructed material is transmitted from the conveyor 27 through the first section 11 and the second section 12 transported to the ballast loading station 30 in the third section 13, where it falls into below, by means of a shunting locomotive (not shown) movable transport cars 32 falls. By advancing and zurückrangieren the transport cars 32 while their uniform filling is guaranteed.

Once all located in the first section 11 track fields are removed from their track bed 18 and transferred by means of the lifting and transporting device 22, 23 in the second section and stored there on the transport cars 25 a, b, the entire device 10 by the length of one of the first section defined track removal field in the direction of the existing old track, so moved to the right in Fig. 1, and then expand the next or end, end track fields in a corresponding manner. To move the device, the support pillar pairs 16 are provided with their own (not shown) hydraulic drive, which consists essentially of extendable hydraulic cylinders, which are articulated on the one hand to the support posts 16 and on the other hand can be supported against the thresholds of the still laid old track. It can be seen in particular from Fig. 2, that the support posts are supported for the purpose of easier mobility with a chassis 33 on the rails 34 of the old track, the front, so the second section 12 limiting support post pair 16a with a height of the buffer 34 of the transport cars 25 arranged cross bar 35 is provided, which applies during the movement or return operation of the device against the rear buffers of the first transport car 25 and thus entrains both located in the second section 12 transport cars 25, so these are moved to the same extent as the device.

Turning now to Figs. 3 and 4, it can be seen that the front support posts 17 are provided with trolleys 36, with which they can be supported on the rails of the old track. However, the front, arranged between the second section 12 and the third section 13 support posts 17 are designed without driving catch for the other two transport cars 32 in the region of the third section; it is preferred here, the transport cars for the removal of the ballast or the like. reposition using the shunting jack, not shown, when the device is moved. The avoidance of a transport stop for the two transport wagons 32 is not least due to the fact that the front support posts 17 are articulated by means of a pivoting device 37 to the support structure 14, with which they from their support on the rails support position (Fig. 3) in a passage position 4, which, for example, after being coupled to the front transport wagons 32, allows the loaded transport wagons 32 to be pulled out together with the latter under the supporting structure and to reposition unloaded transport wagons in the second section in order to receive the next track fields , In the open position shown in Fig. 4, the support posts 17 are therefore not temporarily based on the rails, but with laterally projecting support shoes 39 on the tops of sleepers, whereby the total weight of the support structure including about still located on the conveyor 27 Abraummaterials safely removed becomes.

Unlike the support posts 16, 17 arranged in the area of the second and third sections, the rear support posts on the end section 28 of the first section can not be supported on the rails of the old track that has already been removed there. These support posts 15 are therefore provided with carriage feet 38 or, for example, a crawler track, with which they can be supported directly on the track ballast. The carriage feet or the crawler undercarriage are hingedly connected at the bottom to the support posts 15 and can thus adapt to unevenness in the track ballast. To adjust the height of the support structure or to obtain their uniform height as possible over the entire length, all support posts are designed to be height adjustable and this provided with hydraulic cylinders, with which they can be extended and retracted.

The invention is not limited to the illustrated and described embodiment, but there are various changes and additions to the device and in the process flow possible, without departing from the scope of the invention. The inventive Device can be used in particular not only for the expansion of a track, but also for laying a new track, wherein the described procedures are then performed in substantially the reverse order. With the invention is achieved in a particularly advantageous manner that both consisting of rails and sleepers track superstructure in the form of track fields or track lengths as well as substantially simultaneously track ballast and substructure can be removed and the removed substances can be loaded separately on transport wagons (regular freight cars), without the use of a neighboring track alone using the old track to be removed.
