Definitions

  • the invention relates to a device for applying one-component or multi-component adhesive to a granular mixture, in particular for applying one-component or multi-component adhesive to the ballast of a rail line.
  • the two fluid components are fed from storage tanks via two separate feed lines using gear pumps in precisely controllable flow rates via a mixer unit, thereby producing a fluid sprayable adhesive mixture.
  • a spray unit with at least one spray nozzle or with a spray bar with several discharge nozzles is used to specifically discharge the adhesive mixture onto the ballast bed.
  • one-component adhesives can also be used and conveyed with such a device, with exactly the same structural features of the device.
  • the invention also relates to a method for using this device and its use for applying adhesives, both two-component and one-component, to the ballast of a rail line.
  • ballasted superstructure In long-distance traffic, the ballasted superstructure is the dominant base layer. In urban local traffic, on bridges or in tunnels, however, a solid road surface is used. Adhesive systems offer an efficient solution for both types of construction and for connecting different road surfaces. In the ballasted superstructure as a route, the loosely laid track grid made of rails and sleepers lies in this unbound, compacted ballast bed without any lateral fastening.
  • the ballast bed can absorb considerable compressive forces, but can only be moved within limits under tensile loads.
  • Adhesive systems ensure positional stability quickly and permanently in difficult areas such as rail joints or switches.
  • special measures are necessary to secure the position of the ballast bed. Bonding the ballast shoulders with one-component adhesives or, even better, with two-component resin-hardener mixtures has proven to be an effective method for this.
  • the use of a fast-curing adhesive system saves a great deal of time and money.
  • a particularly difficult area for rail tracks is the integration of different types of construction. Transitions between a ballasted superstructure and a solid track are problematic due to the different settlement behavior.
  • the gradual bonding of the ballast has proven to be an effective measure for equalizing different elasticities.
  • Adhesive systems also offer particular advantages here, namely short waiting times until the load is able to bear the load and the adhesive system's very good environmental compatibility.
  • inner-city local transport it is mainly solid tracks and grass tracks that determine the appearance of rail tracks.
  • the two-component mixtures offer efficient detailed solutions for stabilizing, sealing and designing the track systems.
  • Two-component mixtures can be adapted to the respective situation by varying the mixing ratio of resin and hardener during the curing time and achieve better bonding quality than single-component adhesives, which involve a certain compromise.
  • single-component adhesives are easier to handle because no mixer is required and only a single pump and pipe are needed for delivery.
  • Devices for the controlled pumping, dosing, mixing and dispensing of such adhesives, whether single- or two-component adhesives, using gear pumps, among other things, are also known in principle.
  • Bonding ballast in track construction has various positive effects. Among other things, it enables the tracks to be stabilized and joints to be reduced at transitions from the ballasted track to the fixed track, for example at tunnel entrances and exits.
  • the ballast is usually bonded over the entire surface, including under the rails and sleepers. In order to reduce joints at the transitions between the ballasted track and the fixed track, the penetration depth of the bonding is gradually increased towards the fixed track. Bonding the ballast can not only improve driving comfort, but also the longevity of the tracks, as it prevents the stones from shifting.
  • Bonding the ballast bed in the edge area of a rail line is often of crucial importance if a trench is to be dug near the rail line, or if material is to be excavated next to the rail line as a result of a construction project, such as the laying of another parallel rail line or a building, a retaining wall, etc. or for other construction measures.
  • a construction project such as the laying of another parallel rail line or a building, a retaining wall, etc. or for other construction measures.
  • a channel several meters wide and, for example, 0.5 to 2 meters deep is dug out of the ground, on the bottom of which vehicles such as trucks, dumpers, excavators and other machines can then travel. new railway line.
  • This shoulder proves to be advantageous when laying and maintaining control and signal cables along the tracks, as a trench can be easily dug outside the bonded area and the laid control and signal cables can be easily exposed thanks to the defined, stable shoulder of the ballast bed and the trench can be filled in again after the cables have been replaced without affecting the basic shape of the ballast bed.
  • the ballast bed shoulder stabilized by bonding can still be used with the usual loads despite the trench being dug directly next to the rail line. With a professionally bonded ballast line, it can be cut off to the side and, for example, excavation can be carried out directly next to the ballast bed. Thanks to the bonding, the necessary stability of the ballast line for normal train travel is maintained, which offers enormous advantages.
  • the rail line can also be reinforced across its entire width using ballast bonding using the same device.
  • the application of the adhesives to create such a stable bond requires that the penetration depth of the adhesive into the ballast bed reaches a precisely specified depth everywhere and that the amount of adhesive is applied at a precisely constant rate with a defined spray width per linear meter, whereby multi-component adhesives must always be applied in the correct mixing ratio of the composite adhesive. Furthermore, such a Bonding can be carried out quickly and reliably over larger sections, not just over a few meters. All of the necessary boundary conditions must be adhered to with extreme precision.
  • the application of adhesives can be carried out very professionally, as shown in the document WO 2018/010860 A1, published on 18 January 2018 is comprehensively presented.
  • the device shown there allows the adhesives to be applied in a dosage that sprays a very specific amount of adhesive onto the ballast bed per linear meter, thus ensuring a certain pre-calculated penetration depth.
  • the process carried out using this device is now even certified by the Swiss Federal Railways SBB, which means that its use guarantees that the rail bed will subsequently offer a certain desired load-bearing capacity and can therefore be used as usual by trains weighing several hundred tonnes.
  • the application is inevitably interrupted in order to refill a watering can or to move the supplies, i.e. the containers and machinery for pumping the adhesive to the lance, forward in stages, as these containers and equipment are either carried on a railway wagon or transported by road and set up alongside the track section. If for any reason a malfunction occurs, for example a pump does not work correctly or breaks down, a single component that is toxic in itself can be sprayed in large quantities, which can have fatal consequences for the groundwater.
  • the components of multi-component adhesives may only be applied when thoroughly mixed in the prescribed mixing ratio. Then the mixture hardens reliably and no individual component can enter the soil in isolation.
  • Bonding must always be carried out quickly and determines the penetration depth, because the adhesive runs down through the gravel and as it bonds and hardens quickly, the penetration depth is limited.
  • the work on applying the adhesive has so far usually had to be carried out outside of traffic times and often at night, and dry weather is also a prerequisite for Applying the adhesive. It is clear that there are many boundary conditions and this results in the requirement that a uniform application with precisely defined specifications should be carried out reliably by machine and very quickly on site.
  • bonding is to take place somewhere on a section of rail, for example in a station, or in places that are difficult to access such as bridges, underpasses or overpasses, or generally in places where the side of the rail cannot be accessed by vehicles, it is particularly challenging to be able to apply the adhesive evenly and quickly, if possible in no time at all, i.e. without any interruptions.
  • a particular challenge for the rapid and controlled application of adhesive - with a perfect mixture of components in the case of a multi-component adhesive - and with a consistent penetration depth over long distances in an instant is the fact that large quantities are required for the necessary machinery and storage containers. For example, powerful pumps are required. In addition, an independent energy supply is required, both for the pumps and, depending on the situation, for tempering the adhesive to be applied or its components, which must be available in large quantities. And then all of these devices should be able to be moved along a route. It is a good idea to transport these devices along a rail line in a truck, but this cannot be driven along the track so evenly that the right amount of adhesive per linear meter could be reliably applied with a spray boom attached to it. Or a railway carriage could carry the adhesives and the equipment for tempering, mixing and pumping them separately, but the uniform application of the adhesives could be carried directly from a railway carriage is difficult to realize because it has no drive and has a large dead mass.
  • the object of the present invention is to create a device and a method which can be used even more quickly and flexibly, so that ballast bonding along a rail line can be carried out, depending on the situation, without blocking the rail line in question, i.e. that the time periods between the passing of trains can be used and regular train traffic can continue without disruption.
  • This complete device can be transported by road or brought to the location on the track.
  • the vehicle with the entire device for providing and pumping the adhesive or the adhesive components for the adhesive mixture travels essentially parallel to the track, independently of the train traffic or in such a way that regular train traffic is not hindered.
  • a trolley or a light rail car is placed on the rails within a very short time, approximately within seconds.
  • This trolley or this rail car carries a boom with at least one spray nozzle.
  • the trolley or this light rail car can travel on the rail with an electrical drive at a selectable uniform speed, whereby the boom mounted or molded onto the trolley or the rail car with a at least one spray nozzle moves along the rail at exactly the same uniform speed.
  • the trolley or this lightweight rail carriage can be quickly placed on a rail and put into operation within a few seconds and just as quickly removed from the rail to clear the way for a train.
  • the rail trolley or rail carriage is preferably controlled by remote control.
  • the travel speeds and the GPS coordinates can also be recorded or transmitted and saved live in a cloud.
  • this trolley or light rail car can be supplied by a railway car travelling on a parallel track or the same track instead of a truck travelling alongside the track, which is then gradually pulled or pushed along by a light locomotive or handcar using the spraying device.
  • the trolley or light rail car is then the only thing that ensures the adhesive is applied evenly; a defined amount of adhesive is applied precisely depending on the speed of movement of the nozzles, thus ensuring a precisely defined depth of penetration.
  • a separate light rail car or trolley moves forward evenly on the rail as a spray car, or the spray nozzles can be moved back and forth evenly on this rail car or spray car, so that a predefined depth of penetration is ultimately maintained.
  • FIG. 1 A bonded ballast bed layer is shown, namely a ballast line cut just outside along a rail line, which was previously bonded by spraying on a two-component synthetic resin so that it forms a quasi-monolithic block.
  • the ballast line to be mined can be cut off with an excavator bucket, as shown here, and the bonded ballast shoulder remains stable, so that vertical walls can be exposed without the drivable ballast line losing any significant load-bearing capacity and stability.
  • cables or pipes have to be laid along such a rail line
  • major challenges arise for maintaining the stability of the rail line if it is to continue to be used by trains, i.e. during the installation work for the cables and pipes.
  • the rail line would have to be closed to rail traffic, which would mean major restrictions and expensive downtime for the rail operators.
  • the Figure 2 shows another ballast track stabilized by bonding and then cut off along a track in front of a tunnel portal.
  • a trench often has to be dug over considerable distances, and here the particular problem is how to stabilize a ballast track over longer distances so reliably and safely that it can be certified for use by trains with normal loads.
  • it is removed by hand, no one can guarantee the homogeneity of the bond.
  • bonding by hand is much too slow, requires a lot of personnel, is inaccurate and accordingly expensive.
  • ballast tracks to be bonded in a completely different dimension, much faster and more efficiently, and completely homogeneously, with a precisely consistent, selectable width of the bond and with a precisely definable penetration depth of the adhesive over the entire bond. Only such a mechanical application of the adhesive can be carried out with such precision that the bonding and stabilization can be certified, so that a railway operator can be sure that trains can travel on this bonded route without any problems and are also allowed to do so from an insurance perspective.

  • mixing is preferably carried out by static mixers using gear pumps and the quantity is metered using mass flow meters. This entire equipment as it is installed on such a vehicle is used in WO 2018/010860 A1 described and shown in detail.
  • Single-component adhesives can also be used immediately with the same equipment without any modifications.
  • the measuring wheel 24 or, depending on the model, the wheel 2, 3, 4 acting as a measuring wheel can be seen trailing behind the trolley 1, which provides reliable data on the speed of the trolley 1 to the electronic control unit on the supply vehicle 34 or on the portable electronic device.
  • ballast bed shoulder 32 bonded in this way offers sufficient load-bearing capacity for trains of up to several hundred tons, depending on requirements.
  • the material 38 can be excavated and transported away along the rail route. This area can therefore be exposed safely, while the adjacent rail 16 can still be used.
  • the bonding of the ballast bed shoulder should ultimately make it possible to cut off and remove the hatched area 38 of the route, while maintaining the necessary stability of the route for the trains to pass.
  • trolley 1 together with its boom 22 can be placed on a single rail 16 within a few seconds and can then be put into operation and vice versa, when a train is announced, this trolley 1 can just as quickly be taken off the rail 16 and removed so that a train can pass the work site unhindered.
  • This railway carriage can then be loaded by a locomotive, a trolley or a track excavator in more or less at a constant distance from the rail trolley 1, pushed behind it or pulled ahead of it. It is also understood that these devices can also be transported by a self-propelled two-way vehicle, i.e. by a vehicle that can be driven on both the road and the rail. This vehicle then supplies the trolley device 1 with the already mixed adhesive or the adhesive components to be mixed via cables 36, 37 and hoses 35 in the same way as a road or off-road vehicle 34 traveling alongside the rail line.
  • Such a vehicle 48 running on rails, here with rail wheels 49 that can be lowered hydraulically when required, is in Figure 9 shown as an example and it can travel behind the trolley 1 or alternatively travel ahead of the trolley 1.
  • a vehicle 48 can be replaced by a railway carriage on which the entire device for tempering, pumping and mixing the components of the adhesive is built.
  • This railway carriage then also carries the components for the energy supply, for example an internal combustion engine with generator and batteries for operating the electric pumps and for heating the adhesive to the ideal temperature.
  • railway power can also be taken from the overhead line and made available for operating the device.
  • Such a railway carriage can then travel on a track parallel to the track on which the trolley is placed, which it supplies with conditioned adhesive via pump hoses 35 and is connected to the trolley via cables 36, 37 for control and power supply. It is gradually pushed or pulled along the trolley by a draisine or a light locomotive and therefore does not have to move exactly uniformly with the trolley 1. If conditions permit, this railway carriage can also run on the same track on which trolley 1 is mounted. The rail-compatible road vehicle in Figure 9 is then simply replaced by such a railway carriage.
  • the mixer Preferably a static mixer, in which the spray material is mixed, is attached directly to the rail trolley 1.
  • the Figure 10 shows such a trolley 1 in the form of a light rail carriage on a rail, with a boom 50 for support on the other rail in an elevation.
  • This trolley 1 or this rail carriage has no wheels rolling along the rail from below and can therefore be lifted vertically upwards from the rail at any time.
  • a further advantage of this trolley or this rail carriage is that it can also roll over switches, in that the wheels 51, 52 rolling along the side of the rail head can be briefly lifted upwards, for example pneumatically or electrically, and after passing the switch are lowered back to their original state to roll along both sides of the rail head.
  • the boom 22 is equipped with a device 53 for extending or shortening the boom 22, as well as with a device 54 for adjusting the height of the spray boom 28. These devices 53, 54 can be adjusted by electric motor, pneumatically or hydraulically.
  • a support wheel 55 can be seen, with which the boom 50 is supported in a rolling manner on this opposite rail.
  • the Figure 11 shows this rail car after Figure 10 on a rail, with a boom 50 for support on the opposite rail with, in the example shown, two support wheels 55 for the outer end of the boom 50.
  • Figure 12 shows the rail carriage with its two arms 22 and 50 in an enlarged view.
  • the two wheels 51, 52 which roll on the two sides of the rail head 8 and thus stabilize the rail carriage about its vertical axis so that it cannot twist.
  • the arm 50 with its support on the opposite rail 57, ensures stabilization about the axis along the rail.
  • the spray bar 28 can also be installed on the rail carriage so that it can move.
  • it can be mounted on an arm that extends across the entire width of the rail carriage, whereby the spray bar 28 can be mounted on this arm so that it can be moved by a motor, for example by means of an electric drive.
  • the spray bar 28 can move back and forth evenly across the entire width of the ballast bed of a rail line and ensure that the adhesive penetrates evenly into the ballast bed.
  • This boom can also be designed to pivot about a vertical axis, so that it no longer extends across the rail line, for example, but lengthways, along the rail.
  • the spray bar 28 can then move back and forth along the boom at a uniform rate and thus bond a longitudinal section of the lateral ballast bed, i.e. a ballast bed shoulder, with a constant penetration depth of the adhesive.
  • the Figure 13 shows the part of the rail car with the drive, that is to say its trolley 1, shown separately, in an enlarged and perspective view.
  • the drive wheels 56 are housed inside, with which the trolley 1 rests on the rail, so that its entire weight ensures good adhesion. Between the two drive wheels 56, which can also act as measuring wheels, you can see the electric motor 11 for their drive.
  • FIG 14 This trolley shows the Figures 11 and 12 shown in an elevation. You can see the electric motor 11 and to the left of it the front drive wheel 56, as well as the two guide wheels 51, 52, which roll on both sides of the rail head 8. In Figure 15 is all this is shown enlarged, and in Figure 16 shown in a perspective view. Here you can see the drive belts or roller chains 14, via which the electric motor 11 drives the drive wheels 56.
  • the drive wheels are equipped with a rubber tread 57 to ensure good adhesion.
