Description

The following invention relates to a work cart, a track construction machine and to a setting method for the position of a transfer conveyor of a work car.

In the area of track construction, highly integrated and highly automated track construction machines are used. The tasks to be performed, for example, in the rehabilitation of a railway line of such a machine range from the expansion of the bedding material and the thresholds, to cleaning of the bedding material, supply of new track construction material etc. Such track laying machines therefore have a continuous flow of material, both in the working direction as well opposite, since at the same time old track construction material from the construction site off and new or processed track construction material must be supplied to the workplace.

Here, so-called material handling silo saws are used. Typical material handling silo trucks have bottom conveyor belts that carry the track building material within the cart and transfer belts that transfer the track building material from cart to cart. In addition, there are bypass conveyors that transport track construction material over the storage boxes and also transfer them to the respective adjacent carriages.

On track, the gradient and the lateral position (inclination) of the track are always fluctuating. Due to these fluctuations, such as elevations, curves and crests or troughs (concave or Konvexlagen the rail track), it comes within the track construction machine to elevations or side shifts that affect in particular the material input through the transfer belts.

The transfer conveyors usually have a "basic setting" in relation to the adjacent work car, so that there is an optimal transfer situation with ideally flat straight travel. However, the transfer conveyor belts usually extend a good distance beyond the bogies, which means that when cornering or when driving over hills or troughs, no more accurate transfer is possible because the ends of the conveyor belts cut out. Under certain conditions, the transfer belts can even collide or track construction material be dropped next to the adjacent car.

A readjustment of the position of the transfer belts during operation of the track-laying machine would be possible in principle but is uneconomical and is therefore not practiced, since in principle every work car a worker would have to be assigned for readjustment.

EP 0 490 868 A1 discloses a bulk loader wagon which has a transfer conveyor belt pivotable about a vertical axis, having at its discharge end a centering device which rests on the respective adjacent work wagon to form the work train. The centering device has a transverse displacement drive, so that the discharge end of the conveyor belt can be moved automatically controlled depending on the radius of curvature and / or bank to allow with respect to the track, if possible, an approximately centrally located discharge point.

Based on this prior art, the present invention, the object of the invention to provide an improved work car, which always allows optimal transfer of track construction material to the adjacent work car on different route profiles and in particular both when driving a trough a collision of the discharge ends of the conveyor belts, as well in the case of dome runs a loss of material due to an excessively large discharge gap - in the case of the interaction of the transfer devices of two adjacent carriages particularly relevant - prevents.

This object is achieved by a work cart having the features of independent claim 1.

In addition, there is the task of creating a track construction machine, which also has a low material loss even with bunkering or conveyance of track construction material on the car network across and can be operated more economically than known track-laying machines.

This object is achieved by a track construction machine with the features of claim 9.

Finally, there is the task of creating a setting method for the position of a transfer conveyor of a work car, with the additional without Personnel expenses in each operating condition optimum transfer to the neighboring car can be achieved.

This object is achieved by a setting method with the features of claim 11.

Preferred developments are each described by the subclaims. The work cart according to the invention for a track construction machine has one or more transfer conveyor / s. The transfer conveyor / s are each coupled to an actuator, which are provided for adjusting the position of one or more degrees of freedom of the transfer conveyor / s. The work cart also has one or more measuring devices, each communicatively connected to a control device. The control device is in turn operatively coupled to one or more actuators to effect an operation. The measuring device (s) is / are designed to detect at least one track-related alignment parameter of the work cart in terms of time and space and to transmit it to the regulating or control device. It is inventively provided that the adjusting device is adapted to the position of the transfer conveyor / s with respect to at least one of the degrees of freedom longitudinal axial position, inclination of the transfer conveyor, length and height position of the transfer conveyor by the control or control device depending on the Ausrichtungsparameters during the Driving the work cart.

The work car may be, for example, a material handling silo truck, a pure material trolley, a pure silo truck, a pallet truck, a built-in trolley, such as for track construction material such as substructure material and / or cover layers, for sleepers and / or tracks, a milling trolley, an integrated cable channel laying trolley , a track cleaning wagon, a fractionating wagon, a trolley and / or other known to those skilled work wagons for track processing machines. The above enumeration is hereby merely exemplary; The principle according to the invention of the automatically adjustable transfer conveyor can basically be applied to all working carriages of track processing machines known to the person skilled in the art transferred because basically all the wagons are involved in the material flow.

"Track-related" is intended herein to mean that a concrete reference of the orientation parameter to the course of a track traveled by the work car. This can be understood, for example, a track inclination, track gradient, but also the course of the track in the plane. Track-related does not mean that only relative deviations from the track are recorded, but in particular deviations with respect to the horizontal plane should be recorded.

The work carts are designed to perform various tasks (see above); In this case, for example, new track construction material is transported to a place of installation and / or old track construction material transported away from the construction site and transported to a cleaning car or transported to a repository silo car, that is, on the transfer conveyor any track construction material is transported, which is suitable for track construction material to gravel, Gravel or grit can act in any grain sizes.

By automatically adjusting the transfer conveyor of the work cart as a function of the track-related alignment parameter, the possibility is created for the first time regardless of the used route profile, that is, regardless of inclines, excessive curves and / or track floors, always ensure an ideal transfer situation on the transfer conveyors. For this purpose, no additional human effort is necessary, since the adjustment of the position of the transfer conveyor according to the invention not manually, but by operative coupling of the adjusting device with the control or control device. In addition, the procedure when assembling a track-laying machine consisting of several such work carriages is also considerably simplified since the otherwise customary manual adaptation of the transfer conveyor to ideal straight-ahead driving can likewise be dispensed with. As a result, the operating costs can be reduced, which contributes not only to the cost reduction just described personnel savings, but also a higher recycling rate of expanded track construction material, as lost by the always ideal transfer less track construction material.

The adjusting device may in particular be a setting cylinder, which may be driven hydraulically, electrically or pneumatically. The actuating cylinder is connected at one end to a frame of the work cart and connected at its other end for exerting a force with the transfer conveyor. Alternatively, a support point for the transfer device can be connected as a positive guide point with the actuating cylinder in order to achieve a decoupling of the transfer device from the car body. About the actuating cylinder, the degree of freedom and thus the relative movement to the car body of the transfer conveyor can be set targeted.

In a further embodiment, the transfer conveyor may, for example, be a transfer conveyor belt. The transfer conveyor belt can be arranged, for example, in a roof area and / or in a floor area of the work car. Alternatively or additionally, two or more transfer conveyors may be in pairs next to each other. Furthermore, it is possible that a continuous bypass conveyor belt is provided in the roof area and / or in the floor area. Here, the bypass conveyor at least at one end, that is, task or discharge end, a transfer conveyor associated therewith can be arranged. The bypass conveyors make it possible, in principle, to transport track construction material from a loading point to an unloading point without having to take the "detour" via the storage spaces of the working paths ("bunkering").

In yet another embodiment, the predetermined criteria for adjusting the position of the transfer conveyor may be stored in the control device. The predetermined criteria preferably include a desired position of a discharge point of the transfer conveyor.

Dynamic operating parameters of the transfer conveyor can also be included in the predetermined criteria, for example the instantaneous conveying speed and / or information about the density of the conveyed track construction material.

The control or control device can basically be designed as desired, so it may be a purely mechanical device, an electromechanical, a pneumatic, hydraulic, or else an electrical / electronic Device that has common sensors, actuators and scanners act.

Furthermore, the measuring device can have one or more tilt sensors, wherein the tilt sensor (s) can detect, for example, the track gradient and / or the track inclination. Alternatively or additionally, a position sensor may be provided which detects, for example, a traveled radius of the curve. In addition, at least one sensor may be provided on the work car, which detects one or more chassis parameters of the work car, wherein suspension parameters may be about an angular position of the bogies and / or about an axial offset of the work car. Inclination sensors are known to the person skilled in the art and are available on the market, for which purpose the term "electronic spirit level" is also customary. It is also possible to use so-called weighing sensors or load cells, which are suitable for determining a horizontal or vertical deviation and can determine spatial axis positions therefrom. A position sensor may be, for example, a satellite-supported device or a device which determines a relative position of the work vehicle with respect to track distances of external reference points. The aforementioned list is to be considered as an example only, not as a limitation.

Under track inclination herein is the inclination of the work car or the track distance relative to the horizontal plane in the transverse direction of the track referred to; Track inclination, however, is understood to mean the inclination of the work car or of the track section relative to the horizontal plane in the track longitudinal direction.

The control device may further comprise a data processing device in which a computer program is provided, which is provided for carrying out an algorithm for determining the position of the transfer conveyor.

A data processing device is understood herein to mean a device which has a certain number of inputs for connection to the measuring device (s), a certain number of outputs for controlling the adjusting devices or for relaying actuating signals or input variables of the measuring devices and has an arithmetic unit; For example, a PC or a programmable logic controller. It is known to the person skilled in the art to derive the predetermined criteria for processing the measured values via analytical derivations, controller simulation or the like. The use of a data processing device has the advantage that a manageable costs a relatively high sampling rate of the measuring device can be achieved, for example, several kilohertz, beyond an adjustment of the behavior of the control device is simple, since this only the program code must be adjusted.

In yet another embodiment, the work cart may have one or more other measuring devices that are intended to detect an actual position of the transfer conveyor. The further measuring device is communicatively connected to the control device in order to provide the detected actual position as feedback. As a result, a control of the position of the transfer conveyor is made possible, which is able to compensate for any deviations of the control section.

The degree of freedom of the transfer conveyor is the inclination of the transfer conveyor, the longitudinal axial position, the length and height positions and in particular about a transverse position. Longitudinal and transverse are to be understood here in each case with respect to the track longitudinal direction. The length of the transfer conveyor can be adjusted in particular with telescopic conveyor belts. For a change in the position of the transfer conveyor in the transverse direction can be provided, for example, that the transfer conveyor is moved as a whole, the same applies to the longitudinal direction. To adjust the inclination of the transfer conveyor device is suitably attached to the task point a joint.

The regulating or control device as well as alternatively or additionally the measuring device or measuring devices can be arranged in a housing. Preferably, in this case, a common housing is used, which can be sealed watertight and dustproof and is connected, for example, with a frame of the work car. However, it may also be provided more than a housing which is connected to more than one point of the work vehicle with the frame, for example in the area of the two bogies.

The track construction machine according to the invention comprises a carriage assembly of two or more work cars, between which track construction material is transferred, for which purpose a transfer conveyor is responsible. At least one of the work carriages of the carriage assembly is a carriage according to the invention, it being understood that other work carriages not according to the invention can be used next to it. In the predetermined criteria that are used to adjust the position of the transfer conveyor, it is a target position of a discharge point of the transfer conveyor, the discharge point is located on the adjacent work car. The desired position of the discharge point is set in particular so that it is always exactly centric to the adjacent work car. As a result, optimal bunkering or transfer of track construction material can always be achieved with any track profile, without the risk of eccentric burying or losing material.

Furthermore, the track construction machine may have two or more work carriages according to the invention. The control devices of two adjacent work carriages may be communicatively connected to exchange the track-related alignment parameter detected by the measuring device associated with the other work car. In this way, an optimal adaptation of the individual work carriages to one another can be achieved since, in determining the position of the transfer conveyor, not only the measured values of the "own measuring device" are taken into account, but also the measured values of the measuring device of the adjacent carriage. Suitably, the determination of the desired position of the transfer conveyor in the control or control device of the carriage, is transported from the performed. In the case of a wagon assembly, each wagon that carries away the wagon is at the same time a wagon material accepting wagon, so that in each wagon both the position of the "own" transfer conveyor and the measurements of the adjacent wagon are determined, and the "own" measuring devices are passed on to the adjacent wagon become.

1. a) by means of the measuring device detecting at least one track-related alignment parameter of the work cart and providing the alignment parameter of the control device,
2. b) processing the track-related alignment parameter of the work cart by the control or regulating device, therefrom determining a manipulated value and providing the manipulated value of the adjusting device,
3. c) effecting a position change of the transfer conveyor by the adjusting device and thereby adjusting the position of the transfer conveyor with respect to at least one of the degrees of freedom longitudinal axial position, inclination of the transfer conveyor, length and height position while driving.

This embodiment of the method relates to a track construction machine, in which the adjacent work car is a non-inventive work car, that is, a work car without data acquisition device, adjusting device, etc.

Finally, according to a further embodiment of the method, it may be provided that the control or regulating devices of two adjacent work cars are communicatively connected. In this case, after or during step a), at least one track-related alignment parameter of the adjacent work car is detected by means of the measuring device of the adjacent work car and made available to the measuring and control device of the work car. In step b), the track-related alignment parameter of the adjacent work car is then processed. An adjacent work car is understood herein to mean, in particular, the work car to which the track construction material is to be abandoned. The other work car is the one who passes on the track construction material and has to be set transfer conveyor.

In Fig. 1a to Fig. 1c a section of a track construction machine 1 according to the prior art is shown, wherein only two work carriages are shown 2,2 ', namely two material handling silo trucks (MFS cars). The work cars 2 each have two bogies 21, with which the chassis is connected. Inside the work carriages 2, 2 'there is a storage box 22. Since a continuous material flow always takes place in the track-laying machines 1, the MFS carriages 2, 2' each have a transfer conveyor 3 at their left-hand end in FIG In the embodiment shown, a transfer conveyor belt 3 is arranged in the bottom area, wherein a horizontal conveyor belt section 32 is provided to convey the track construction material onto the inclined section of the transfer conveyor belt 3. The transfer conveyor belt 3 is in this case pivotable about a pivot point 31 to allow an adjustment of the discharge point.

The transfer conveyor belts 3 are arranged centrally with respect to a frame of the work cart 2 or the storage container 10, so that a transfer of the track construction material to the adjacent MFS carriage 2 can take place exactly in the middle, in order to enable homogeneous weight distribution and storage space utilization.

Does the track construction machine 1 now not a straight line, but a curved track, so the track building material can not be exactly centered on the adjacent work car 2 'are unloaded, this is in the Fig. 2a to Fig. 2c shown. Since the transfer conveyor belt 3 protrudes significantly beyond the bogie 21 out, results in Bogenfahrt a shearing from the longitudinal center plane (normal standing on the tracks level, which runs through the center of the work car 2,2 ') in Fig. 2c is symbolized by the distance d; the result is that the unloading of the conveyed material is eccentric, with disadvantages in terms of not optimal weight distribution; In addition, track construction material can be lost because not the entire conveyed the storage box 22 of the work car 2 'hits.

This is where the invention comes in: In order to enable a centric ejection of the track construction material on the adjacent work car 2 even when driving on curved track sections the transfer conveyor belt 3 is not centrally fixed, but can be moved transversely to the track longitudinal direction; this is in the plan view of Fig. 3a shown, wherein the transfer conveyor belt 3 of the right working car 2 has been moved in a downward direction in the figure (arrow). In this position, the track construction material is dropped even at Bogenfahrt on the optimally centric discharge point of straight ahead. For clarity, the front view of the Fig. 2c referring to the eccentric state of the transfer conveyor 3; the corrected centric state is in the front view of the Fig. 3b shown. The offset d was eliminated by the shift by the same amount.

In order to achieve a quick and cost-effective adaptation of the discharge positions of all transfer conveyors 2 in a track construction machine 1, which can be accomplished with a low staff effort, the invention proposes to use a measuring device on each of the work carriages 2. The measuring devices detect at any time parameters on the spatial track-related orientation of the respective work car 2. This can for example be done to detect curves or track curves by measuring the deflection of the bogies 21; Tilt sensors can be used to detect inclines or inclines. The measured values of these measuring devices are made available to a control or regulating device which automatically determines the optimum deflection of the transfer conveyor belt on the basis of predetermined criteria. This will cause the loss Track construction material significantly reduced. If, for example, the track conveyor material to be reprocessed is transported by the transfer conveyor belts 3, the loss must be compensated by new track construction material; the present invention maximizes the degree of refurbishment, ultimately reducing the cost of track rehabilitation.

However, a concrete handover situation is characterized not only by the orientation parameters of one work cart 2 but also by the relative orientation to the adjacent work cart 2 '(the cart to which the track building material is applied). In determining the optimal (desired) deflection of the transfer conveyor belt 3 is therefore intended to include the alignment parameters of the adjacent work car 2 'with; for example, the right working car 2 in the figure can still be on a curved piece, but the left working car 2 'in the figure is already on a straight piece of track; In this case, the target deflection of the transfer conveyor belt 3 would be different than when both work carriages 2 are in a curve; The same applies to "S-curves" or the like. Advantageously, it can then be provided that the adjacent work car 2 'provides the measured values recorded by its measuring devices to the work car 2 ("working car"), whereby both the measured data of the adjacent work car 2 'as well as the measurement data of the work cart 2 ("receiving work car") are processed by the control or regulating device of the issuing work cart 2.

Alternatively, in the case of a track construction machine 1, a central regulating or control device may also be provided, to which the measuring data of all measuring devices of all the working carriages 2 of the carriage group are fed and processed by the same.

To adjust the transverse displacement of the transfer belt 3, an adjusting device 4 is provided according to the invention, which in the Fig. 4a and 4b is shown. In the adjusting device 4 is an actuating cylinder, which is connected to the exercise of a force with the transfer conveyor belt 3 and which is supported on the frame of the work car 2. The Fig. 4a, b show both the deflected (eccentric) state and the state after correction. The cuts refer to the Fig. 2b or. Fig. 3a ,

However, the invention not only covers the automated (lateral) correction of the position of the transfer conveyor belts 3 when cornering, but is also optionally applicable to uphill, downhill, uphill and trough trips, ergo for height correction.

The in the Fig. 5a to Fig. 5c shown carriage assembly of two work cars 2,2 'has in addition to the arranged in the bottom area transfer conveyor belt 3 in the roof area a continuous bypass conveyor belt 52, the both ends with an associated transfer conveyor belt 51 and 51' is equipped. In ideally flat straight ahead driving there is a defined transfer gap d between the adjacent transfer belts 51 and 51 '(see Fig. 5c ).

If the carriage assembly now carries a track group, there is a risk that the two zuender pointing transfer belts 51,51 'collide; see also Fig. 6a to Fig. 6c , where in Fig. 6c It can be clearly seen that a collision is imminent, since the transfer gap is no longer present and the transfer conveyor belts 51, 51 'touch one another.

In order to prevent this, an adjusting device 4 is provided according to the invention, which acts on the transfer conveyors 51, 51 'in the vertical direction, so that the optimum transfer gap d is maintained even when the dipper runs. See the Fig. 7a and Fig. 7b , A correction of the height direction is also provided in the event of a well passage, in which the transfer gap d tends to be too large, which in turn is associated with a loss of conveyed; ie, according to the invention, any height deviation from the ideal transfer gap is corrected automatically according to the sampling rate of the control device.

A possible embodiment of the adjusting device for adjusting the height position of the transfer conveyors 51,51 'is in the Fig. 8a to Fig. 8d shown. Here correspond to the Fig. 8a and Fig. 8b the Fig. 6a and Fig. 7a , Is the fact, however, being made to the details C and D. Fig. 8c shows the state of imminent collision of the transfer conveyor belts 51,51 '(no transfer gap) while Fig. 8d shows the state with controlled transfer gap d; the direction of travel of the actuating cylinder 4 is indicated by an arrow.
