Description

The The invention relates to a method for laying U-shaped channel elements next to the track of a railway line according to the preamble of the claim 1.

Next The tracks of railway lines is often a laying of cables necessary. These serve to electrify the track. Because of this Cable lines will be switches, level crossings, signal systems or other facilities of any kind electrically operated.

To the Laying the cables serve U-shaped channel elements, in which the cables should run. To be laid U-shaped channel elements usually installed as standardized sizes. They are in the Materials concrete or plastic available. Usually they have one length of 0.5 to 1.0 m. The installation of these U-shaped channel elements takes place doing so in a fixed distance to the side of the track. The U-shaped channel elements will be buried in the soil so that their upper edge preferably flush concludes with the soil or something sticking out of the ground.

To the Laying the U-shaped Channel elements will be first dug a ditch. Serve known excavation equipment such as excavators or the like, which accomplish the excavation. After the excavation will be first before inserting the U-shaped channel elements a split-sand mixture or einkornbeton installed. this happens usually with a strength from 5 to 10 cm. Subsequently Then in a further operation, the U-shaped channel elements moved to the installation site and installed on the previously installed pad. Finally, it will the soil in another operation again laterally on the U-shaped channel installed and leveled and compacted.

It Thus, a plurality of individual steps are required, around the U-shaped Laying channel elements. This means that the laying of the U-shaped channel elements intermittently and accordingly accordingly is slow.

From that On the basis of the invention is therefore the object of a method for laying U-shaped Channel elements next to the track of a railway line for subsequent laying of cables with a much higher performance compared to create the previous installation methods.

The technical solution is characterized by the features in the characterizing part of claim 1.

Thereby is a method for laying U-shaped channel elements next to the track of a railway line for the subsequent laying of cables created whose performance is much higher than the previous one Modes of incorporation. The basic idea of the process according to the invention lies in one Duct laying machine consisting of one or more work cars, which are moving forward continuously and all the work required to lay the U-shaped channel elements or semi-automatically. Through this continuous operation, the work becomes in comparison to the known cyclic working techniques considerably elevated. The basic idea lies in a rail-bound, independent machine, the special work car for owns special work sections. So first the excavation is carried out, then becomes the split or the like. Built and finally the U-shaped channel elements used in the ditch. This means a maximum of automatic execution all work steps. The machine is designed in this way that all common standardized U-shaped Channel elements can be installed. But it is also basically conceivable that special forms of U-shaped Channel elements with larger individual lengths installed can be.

The basic idea of the development according to claim 2 lies in the use of a corresponding trench lifting device in a track-bound or track-guided, continuous method for excavating a trench of a railway line parallel to a track. The excavator performs the excavation of the U-shaped trench so accurately and continuously that no separate backfilling is required. When using a milling device preferably corresponds to the width of the trench exactly the channel to be excavated. This excavation of the trench is carried out continuously during the course of the machine activity. The advantage is a continuous operation with associated high power rates in a single operation. The excavation takes place by means of a corresponding excavating both in layers of earth and optionally in rock layers, depending on the needs and requirements of local conditions. Thus, a continuous execution of all steps in a single pass and even at long distances to the track outside the track area is guaranteed. The technical realization thus provides that it is a continuous excavation of the trench. This means that the work car travels continuously on the track and that a corresponding excavation device is arranged on this work car, which synchronously digs out the trench during the forward movement of the work carriage and the excavated material immediately before or after the work car other work car or a work car on a parallel track supplies. Thus, a rail-mounted excavator in the form of a stand-alone, heavy machine on the work car created that ensures a continuous excavation in particular by means of a router in great depths of several meters and with long distances to the track axis of several meters. The excavated material is loaded directly after the excavation in a continuous operation for disposal. The excavated material can be transported by means of a conveyor belt to conventional upstream or downstream or located on a neighboring track railway cars.

A preferred training proposes according to claim 3 that the Excavated material is milled by the excavating device. It is thus a track-guided or track-bound trencher. The milling has the advantage that it a continuous workflow in the Sense of continuous forward motion of the work car is.

The technical realization of the trencher looks according to the development in claim 4, that as milling device an endlessly circulating band or an endlessly circulating chain or Like. Is used, which is equipped with cutting elements. The advantage of such a milling device is that a continuous excavation up to great depths of several meters as well as with big ones lateral distances to the track of several meters is possible. Here is the milling device preferably interchangeable. By different width milling equipment can Thus, different widths ditches are easily excavated.

there corresponds according to the development in claim 5, the width of the milling device preferably the width of the trench to be excavated. This means, that in a single operation with a single forward drive the milling device the trench dug according to the required dimensions can be.

A preferred training proposes according to claim 6 that the Excavation device on a transverse to the direction of movement of the work car telescopic boom is arranged. This cantilever boom, at the end of which the excavating device, in particular the milling device has the advantage that long distances between the track and the trench to be excavated, and Although distances of several meters. The milling device can be pivoted be around it obstacles, for example in the form of masts to be able to. The stable leadership the excavating device is due to the compact design of the work car with the appropriate structure for reached the excavation. The weight of the unit described above serves to the tilting moment of the overhanging excavating device counteract. The weight can also be optionally variable chosen By, for example, the work car with additional weights equipped becomes. Thus, a continuous execution of all steps in a passage even at large time distance to the track guaranteed.

The Training according to claim 7 has the advantage that on technically simple way very large depths of several meters can be dug. Furthermore is a possibility created for avoiding obstacles. Thus, the Telescopic arms the milling device in their required position in terms of height and direction as well as in terms of Keep the inclination by a corresponding pivoting movement.

The Interchangeability of the excavating device on the work cart according to the development in claim 8 has the advantage that according to the variable Construction site requirement profiles corresponding excavation facilities can be used. The interchangeability but also has the advantage that others Tools as excavation equipment attached as an optional additional solution can be for example, drills or compactors or other tools of any kind.

The Training according to claim 9 has the advantage that the Positioning of the excavating device, in particular the milling device automatically in terms of height and side position as well as in terms of inclination automatically regulated without the grave dimensions must be measured by hand. Thus, the automatic tilt regulation of the milling direction for example about Laser control in dependence take place from the depth and width of the digging trench. Consequently the complete device can be semi-automatic or fully automatic in particular by means of a laser control.

The Respectively the excavated material to the work car can claim according to the development 10 by means of a conveyor belt respectively. Thus, the track-bound or track-guided excavating device in particular in the form of a trencher with a conveyor belt technology combined in that a direct discharge of the excavated material on a connected conveyor belt in the continuous Operation takes place.

Preferably, according to the embodiment in claim 11, the conveyor belt to a verti pivotable kale axis. In this way, the excavated material can be loaded both on railway wagon head or even on a neighboring track vehicle or a road truck.

The Training according to claim 12 sees a bunker car for the split material in front. The trams give it the funding from the bunker car on conveyor belts. It can at Need multiple bunker cars to be coupled in series to enough split material to be able to transport.

A preferred training proposes Claim 13 to the effect that after the excavation of the trench through the lateral soil of the trench lateral support boards supported becomes. These support boards are preferably made of sheet metal or steel. For this purpose is the support device preferably arranged on a telescopically projecting arm, which the support boards can position exactly in the excavated channel. An essential Aspect is that this lateral support boards synchronous with the forward drive the work car carried become. This means that immediately after digging the trench, the support boards come into effect and protect the trench from collapsing laterally. These supporting boards thus define a so-called ongoing shoring. The lateral ones supporting boards can thereby by a U-shaped Be defined profile. The floor (or the ceiling) thus forms the rigid structural connection between the two lateral support boards. This floor or the ceiling does not need it over the whole length to this support device extend. It is enough that the Soil just over one partial length is trained. Where there is no ground, then, for example the split be introduced. Are then the two side support boards still by a horizontal, web-like scraper with each other connected, the introduced split can be smoothed and compressed if necessary.

The Training according to claim 14 hits the previously mentioned Variant ago, that the The split of the trench is smoothed by a scraper and possibly compressed. This means that first the bottom of the split or Like. Is abandoned, the entrained scraper pulls off the split and, if necessary, pre-compressed. This therefore represents a possibility to be without big Effort the excavated trench to supply the soil split. It is only necessary that of a corresponding reservoir of the Working car of the stockpiled there, for example by means of a conveyor belt is fed to the trench.

As previously also executed, is the scraper according to the development in claim 15 preferably on the support boards of the ongoing Verbaus for support formed of the lateral soil. This represents a technical simple measure on the one hand for supporting of the lateral soil and on the other hand for stripping the abandoned Splits

A further development proposes according to claim 16, the storage of the U-shaped channel elements on the work car. In this case, the stored U-shaped channel elements can be supplied to the trench by means of a corresponding feed device. As a feeder, for example, serve a conveyor belt, which extends laterally next to the work car obliquely in the direction trench. As a result, the U-shaped channel elements are supplied to a certain extent obliquely from behind the trench. The corresponding installation device of the U-shaped channel elements can additionally serve as a running shoring for the lateral support of the soil. However, it is also conceivable in principle that the mounting device with the side boards described above are immediately after the excavation combined with each other, so that there is already the installation of the U-shaped channel elements after previously been abandoned in the area of these side boards of the split floor. As a result, an upper carriage may be less necessary in the optimal case. However, the functions and principles of the two units described above remain the same. They are only united in a facility in the ditch area. In principle, a special transport vehicle can be provided for the U-shaped channel elements. Here the factory-palletized or specially nachpalettierten from the factory U-shaped channel elements can be transported by means of a gantry crane to a depositing trolley. This Ablegewagen is thus equipped with the above-described feeder. The gantry crane moves here on its rail wheels on flank rails of train carriages coupled in series. The gantry crane is equipped with a pallet fork or other lifting device, which are capable of transporting the palletized, U-shaped channel elements. The Ablegewagen takes from the pallets a fractional unit of U-shaped channel elements and places them on a cross conveyor belt. The cross conveyor transports the U-shaped channel elements to a transfer conveyor. Since the U-shaped channel elements store on standard pallets, after emptying this palette, a quick clearing must be possible. For this purpose, an additional cross conveyor the pallet can be driven immediately after emptying from the storage area for the new, filled pallet. This ensures that a continuous work progress is guaranteed. To ensure a continuous supply of U-shaped channel elements, several trolleys for the U-shaped channel elements be strung without a trolley. A gantry crane moves from one wagon to another to transport the pallets. He can transport both the old pallets and the new pallets to the intended workstation.

The Training according to claim 17 beats before that the Machine all measurement-relevant activities via a corresponding position control, In particular, laser control can run independently. This concerns the Distance to the track, the altitude the U-shaped Channel elements and the lateral position of the channel, as well as the displacement of the Channels during the Working process, namely warping during the forward movement.

Finally, the training suggests according to claim 18 ago that after the installation of the U-shaped channel elements the lateral soil is recompressed and / or smoothed. This can be done by means of a flank compressor, which the Laterally located adjacent to the channel earth material and even.

One embodiment a device for the method according to the invention for laying U-shaped Channel elements next to the track of a railway line for subsequent laying of cables is described below with reference to the drawings. In these shows:

1 a single view of the device for digging a trench;

2 a section along the line AA in 1 ;

3 a side view first with the in 1 and 2 described excavating device, then a feed unit of split in the trench and finally a unit for supplying U-shaped channel elements;

4a a section along the line BB in 3 ;

4b a section along the line CC in 3 ;

5 a side view of the carriage for storing the U-shaped channel elements;

6a a section along the line DD in 5 ;

6b a section along the line EE in 5 ;

7 a view of the supply of the U-shaped channel elements to the trench.

First, in the 1 and 2 the device for digging a trench shown in a single view.

On a track 1 a railway line is a work car 2 with a superstructure 3 traversable. Task of this work car 2 with an appropriate tool, it is by far the side of the track 1 a ditch 4 dig.

For this purpose, one is at the superstructure 3 of the work cart 2 laterally projecting, telescopic boom 5 intended. At the outer end of this jib 5 there is an excavation facility 6 , This excavating device 6 is as a milling device 7 in the form of an endless circulating band 8th with milling elements on it 9 educated.

Furthermore, a conveyor belt 10 intended. This opens with its front end above a - not shown - another work car 2 on the same track 1 or on a neighboring track. This conveyor belt 10 is pivotable about a vertical axis.

The operation of the trenching apparatus is as follows:
First, the telescopic boom brings 5 the milling device 7 the excavating device 6 in the correct lateral distance with respect to the track 1 , But it is exactly the place where the ditch 4 to be dug.

Then the milling device 7 pivoted by a corresponding drive down, with an inclination angle, as in 1 is recognizable. Through the endless circulating band 8th is by means of the milling elements 9 milled the soil, leaving the ditch 4 arises. It is essential that during this milling process of the work car 2 continuously moving forward. This means that during this forward drive of the work car 2 the soil continuously by means of the milling device 7 is milled and thus according to the forward drive of the work car 2 the ditch 4 is created. By a height adjustment of the boom 5 at his superstructure 3 of the work cart 2 and / or by the inclination of the milling device 7 can the depth of the trench 4 be predetermined. The control is preferably carried out automatically by means of a laser positioning.

That of the milling device 7 milled excavated material 11 gets the conveyor belt 10 given up. This conveyor belt 10 is pivoted about its vertical axis such that the front end of this conveyor belt 10 the excavated material 11 in egg nen corresponding reservoir throws off. It can be the work car 2 to a behind or in front of the work car 2 to a work car 2 on a neighboring track or around a truck.

After getting into the soil 12 the ditch 4 has been introduced, there is a risk that the lateral soil 12 in the ditch 4 breaks. For this reason, following the excavation 6 a support device 13 for the side walls of the trench 4 intended. For this purpose, a U-profile with lateral support boards is used 4 , This is on a telescopic cantilever 15 arranged such that the U-profile in such a way in the trench 4 sticks out that the lateral support boards 14 at the side of the ditch 4 abutment and the soil 12 support. It is essential that this through the support boards 14 formed Verbau synchronously mitfährt. This means that immediately behind the excavator 6 the support boards 14 be tracked. Another special feature of the support boards 14 defining U-profile is that this only in the front area has a bottom (which the support boards 14 rigidly spaced), while the bottom is omitted in the rear area.

Because this bottomless area of the U-profile is split 16 fed. This is in a storage container 17 stored. This defines together with a transport device 18 in the form of a conveyor belt, a split-feeding device 19 ,

The functionality is as follows:
The in the storage container 17 stocked Split 16 is via the obliquely forward transport device 18 in the form of the conveyor belt the ditch 4 fed, in the area of the U-profile, which the side support boards 14 Are defined. Specifically, the split 16 supplied to that region of the U-profile, which has no bottom. This means that the split 16 directly to the underground of the excavated trench 4 is supplied.

However, located at the rear end of the two support boards 14 a transverse scraper 20 , This sweeps the passing below split 16 smooth and compact it if necessary.

Finally, a channel element insertion device 21 intended. This has the purpose of U-shaped channel elements 22 via a feeder 23 the ditch 4 , which in the meantime in the ground area with split 16 is provided to supply.

The channel element insertion device 21 initially has U-shaped channel elements 22 on which on the work cart 2 palletized (in 5 far left). By means of a gantry crane 24 become the palletized U-shaped channel elements 22 to a storage unit 25 transported. The gantry crane 24 travels here on rail wheels on flank rails of train carriages coupled in series. The gantry crane 24 is equipped with a pallet fork or other lifting device, which is used to transport the palletized U-shaped channel elements 22 serves.

The storage unit 25 takes from the pallets a fractional unit of U-shaped channel elements 22 and put them on a cross conveyor 26 from. The cross conveyor 26 transports the U-shaped channel elements 22 to a transfer conveyor, which the feeder 23 Are defined.

From there, the supply of the removed U-shaped channel elements takes place 22 to a mounting device 27 , This is essentially designed as a U-profile and serves equally for lateral support of the soil 12 in the ditch 4 , In this way, the U-shaped channel elements rank 22 after being installed in series one behind the other.

In 6b Yet another function of the trolley for the U-shaped channel elements is shown. Since the U-shaped channel elements store on standard pallets, a fast clearing must be possible after emptying the respective pallet. For this purpose, an additional cross conveyor belt 28 provided, which drives the empty pallet immediately after emptying from the storage area for the newly filled pallet. This ensures that a continuous work progress is guaranteed. It can thus more cars for the U-shaped channel elements 22 be strung so as to provide a continuous supply of the U-shaped channel elements 22 to ensure. The gantry crane 24 moves to transport the pallets over the rails from car to car. Thus, the gantry crane 24 transport both the old pallets as well as the new pallets to the designated place to settle.
