Definitions

  • the invention relates to a rubber wheel roller for compacting a soil, in particular for asphalt compaction. Moreover, the invention relates to a method for controlling a sprinkler system of a rubber wheel roller.
  • Generic Gummiradwalzen are typically used for soil compaction and especially in road construction for asphalt compaction. These are self-propelled construction machines, which usually have a machine frame, a drive motor and a drive motor driven chassis with a front chassis part and a rear chassis part. Typically, at least one chassis part comprises at least two juxtaposed wheels with treads.
  • the wheels are usually made of an elastic material, such as a rubber material. During the driving over of the ground, the elastic properties of the wheels result in a kneading or rolling effect which results in a particularly good pore closure on the surface of the layer to be compacted when generic rubber wheel rollers are used.
  • the operator of the rubber wheel must therefore estimate or observe when the asphalt material threatens to adhere to the wheels no longer. Once the wheels are sufficiently heated, then the sprinkler system can be switched off. If this happens too early, there is a risk of damaging the asphalt layer by detaching pieces stuck to the wheels. However, if the operator shuts down the sprinkler too late, too much release agent is consumed unnecessarily.
  • the solution should be as inexpensive as possible.
  • the solution succeeds in a Gummiradwalze mentioned above in that a temperature sensor is present, which is designed and arranged such that it determines the temperature of at least one wheel, in particular the running surface of the wheel.
  • a basic idea of the present invention is therefore to directly determine the temperature of the wheel and in particular the contact surface of the wheel to the ground, that is the tread.
  • the temperature is now determined directly at the point where the adhesion of the asphalt material threatens.
  • Particularly suitable for use with the invention are contactless, for example optical, temperature sensors. These can be arranged in the vicinity of the wheels, for example in the wheel arch of the rubber wheel roller, and from there they can be aligned with the running surface of the wheel.
  • the arrangement does not have to be in the immediate vicinity of the wheel, but it is only important that the temperature sensor is arranged so that the wheel to be measured is in its measuring field.
  • at least one measuring point of the temperature sensor must lie on the wheel, in particular on the running surface of the wheel.
  • the temperature of the tread of the wheel is a quantity more directly related to the adhesion of asphalt material than merely the temperature of the ground, since the latter does not provide information about the heating state of the rubber wheel itself.
  • the measured temperature of the wheel, in particular the running surface of the wheel can be displayed to the operator of the rubber wheel roller, which makes it much more accurate to estimate whether or not adhesion of asphalt material is still to be feared.
  • the operator can therefore adapt the switching on and / or off of the sprinkler system much more precisely to the actual need for sprinkling, as a result of which a total of separating agents is saved.
  • the sprinkler system is fully automatically controlled by a control unit which accesses the temperature value of at least the temperature sensor for controlling the sprinkler system, in particular for switching on and / or switching off the sprinkler.
  • the temperature sensor is an optical temperature sensor with a measuring field and at least one measuring point.
  • the temperature sensor may thus be designed as a thermal imaging or infrared camera.
  • the temperature sensor comprises an infrared sensor array, or the temperature sensor is designed as an infrared sensor array.
  • An infrared sensor array is a measuring device with which the temperature of several measuring points can be determined at the same time.
  • An infrared sensor array can be considered, for example, as an infrared camera with only a few pixels or pixels representing the measuring points.
  • an infrared sensor array can have 16 ⁇ 4 pixels or measuring points.
  • a temperature scanner can also be used. This essentially has only a single measuring point, but directs it alternately to at least two points of a rubber wheel and / or at least one point in each case on at least two rubber wheels.
  • Rubber wheel rollers usually have a plurality of juxtaposed wheels.
  • the wheels may have different temperatures.
  • the Gummiradwalze partially drive on an already cooled asphalt stripe and partly on a hot asphalt stripe, whereby the respective hot or cold asphalt coming into contact with the wheels have different temperatures.
  • the optical temperature sensor is designed and arranged such that the measuring field comprises at least one measuring point on at least two wheels, in particular on the running surface of the respective wheel.
  • the at least two wheels can be arranged next to one another, for example.
  • it may be, for example, two adjacent wheels, which are arranged transversely to the direction of the rubber wheel on the left or the right outer side of the chassis part.
  • the wheels arranged transversely to the working direction often have a different temperature to the wheels arranged further inwardly next to the outer wheels. This is because the wheels located further inside are already shielded from the environment by the outer wheels. It is therefore to be expected especially between these wheels with a temperature difference.
  • the optical temperature sensor is designed and arranged such that the measuring field comprises at least one measuring point on each wheel of the respective chassis part, in particular on the running surface of the respective wheel.
  • the temperature of each wheel of the chassis part is determined by the temperature sensor. This information can then be displayed to the operator or used directly to control the sprinkler, for example, as will be described in more detail below.
  • the temperature data for each individual wheel is known, it can be decided particularly efficiently whether the sprinkler system has to be activated or deactivated, depending on which wheel is traveling at what temperature on the hot asphalt material. In this embodiment also comes the advantage of using an infrared sensor array especially for carrying.
  • An infrared sensor array can be arranged on the rubber wheel roller, for example in the wheel arch of the chassis part or on a provided for this chassis part thermal apron or its holder, that the temperature of each wheel of the chassis part is measured by the temperature sensor. At least one pixel of the measuring field therefore lies on each one of the wheels. In this way, with only a single temperature sensor, the temperature of all wheels of the chassis part can be determined.
  • the solution according to the invention is therefore particularly cost-effective, since it is not necessary, for example, to use a separate temperature sensor for each individual wheel to be measured.
  • the invention can also be used to advantage in rubber wheeled rollers, in which both the front chassis part and the rear chassis part has wheels.
  • a total of two optical temperature sensors are present, wherein an optical temperature sensor determines the temperature of at least one wheel of the front chassis part and the other optical temperature sensor determines the temperature of at least one wheel of the rear chassis part.
  • the two temperature sensors each determine the temperature of all arranged in the respective chassis part wheels.
  • This information can be used by the operator of the rubber wheel roller, who is shown the corresponding measurement results, in order to realize a particularly efficient control of the sprinkler system.
  • Both temperature sensors are particularly preferably designed in each case as an infrared sensor array or temperature scanner.
  • a display device is provided, via which the operator can see the temperatures of the wheels which are determined by the temperature sensor. The operator can therefore decide on the basis of the wheel temperature, whether a sprinkling with release agent by the sprinkler is necessary to prevent adhesion of asphalt on the wheels.
  • the control unit is designed to independently control the sprinkler system based on the measured values of the temperature sensor, in particular at least to activate and / or deactivate. This can be done in addition or alternatively to the presence of a display device. It is thus provided that the control unit directly controls the sprinkler system automatically on the basis of the temperatures of the wheels measured by the temperature sensor or the temperature sensors, without the operator having to additionally act for this purpose.
  • the control unit activates the sprinkler when the temperature of the at least one wheel is below a predetermined threshold.
  • the control unit may deactivate the sprinkler if the temperature of the wheel is above or below the predetermined threshold.
  • different threshold values can be preset here. Typical threshold values are for example in the range from 60 ° C to 110 ° C, in particular at 80 ° C. The concrete appropriate threshold depends on the softening point of the bitumen grade used in the bituminous mixture.
  • the rubber wheel roller or the above-mentioned control unit is selectively switchable to a "rolling mode” and / or “sprinkling mode", in particular to prevent that during normal driving outside the rolling operation, ie when the ground and the Wheels are cold, the sprinkler system is automatically activated by the control unit.
  • the control unit is designed to irrigate the wheels arranged on the outside of a working direction separately from or between them Steering wheel wheels.
  • the sprinkler is at the same time designed such that it can sprinkle the transversely to the direction of the outside wheels arranged independently of the other wheels of a chassis part. As already indicated, it sometimes happens that the wheels of a chassis part lying transversely to the working direction are colder than those lying between these wheels.
  • the control unit stops the irrigation of the inside wheels, while the transverse to the direction of the outside wheels of the chassis part are further sprinkled until they have reached the necessary temperature.
  • the control unit be so designed to control the irrigation of each individual wheel independently of the remaining wheels.
  • the sprinkler system is designed such that the irrigation of each individual wheel can be activated or deactivated independently of the other wheels.
  • the sprinkler on a spray bar which has its own spray nozzle for each wheel, each spray nozzle has its own valve, which is individually controlled by the control unit. In this way, the control unit can respond to any asymmetry in the temperatures of the wheels individually.
  • the control unit activates the sprinkling at those wheels whose temperature is below a predetermined threshold, while the control unit deactivates the sprinkling of those wheels whose temperature is above a predetermined threshold.
  • the above-mentioned thresholds can be used. Due to the control of the irrigation of each individual wheel independently of the other wheels, the sprinkling with separating agent is actually carried out only at those wheels and in the temperature range in which adhesion of the asphalt material to the wheels is possible. The release agent is thus used very efficiently and greatly reduces the consumption of the release agent.
  • the temperature sensor is designed and arranged such that in addition to the temperature of the at least one wheel, the temperature of the soil is also determined. In other words, at least one measuring point of the measuring field of the temperature sensor is located on the ground, so that its temperature can be measured by the temperature sensor.
  • an infrared sensor array which has sufficient pixels or measuring points to cover all the wheels of a chassis part as well as the ground and to determine the respective temperatures. It is particularly preferred if, in addition to the temperature of each wheel, the temperature of that floor section over which this wheel travels is also determined. For each wheel of the rubber wheel so two temperatures are measured, which correspond once to the running surface of the wheel and once the surface coming into contact with this tread surface.
  • the temperature of the soil can then be taken into account by the control unit in the control of the sprinkler system.
  • the control unit is designed to activate the sprinkler through the sprinkler system when the temperature of the floor is above a threshold value, and to deactivate the sprinkler system when the temperature difference between floor and wheel falls below a predetermined threshold value.
  • This procedure is preferably hierarchical, specifically such that only with previously activated sprinkler, i. "warm soil", which would trigger an activation of the sprinkler system on the basis of the temperature, due to the determined temperature of the soil above a threshold value, the determined temperature difference is used for deactivation.
  • the threshold for the temperature of the soil or of the asphalt layer, above which the sprinkler system is activated by the control unit is for example between 40 ° C and 80 ° C, for example 55 ° C.
  • the automatic activation and deactivation of the sprinkler system prevents the sprinkling from being switched on too late and the asphalt material from adhering to the wheels is. In addition, it prevents the unnecessary use of the irrigation emulsion, although there is no danger of buildup.
  • a device for, in particular optical, detection of the outer surface of at least one rubber wheel for example a digital camera
  • image processing software it can be used to determine whether or not adhesions actually occur.
  • This information can also be displayed to the operator of the rubber wheel roller and / or be used to control the control unit of the sprinkler, for example when the driver sets manually at least one threshold value.
  • control unit is adapted to the previously activated irrigation by the sprinkler to turn off automatically when the determined temperature of the soil is below a threshold value. So if the asphalt material has already cooled so far that no sticking to the wheels of the rubber wheel roller is more to be feared, the previously activated sprinkler system is automatically deactivated and thus unnecessary consumption of release agent is prevented.
  • This switching off also preferably relates to the sprinkling of each individual wheel individually based on the temperature of that floor section over which the corresponding wheel travels.
  • control unit is designed to stop the irrigation by the activated sprinkler system when the temperature difference between the ground and the wheel falls below a predetermined threshold. In this way, separating agent is saved when an adhesion of the asphalt material to the wheel due to cooling of the material by the contact of the wheel is no longer to be feared.
  • the above-described control of the sprinkler system for each individual wheel of the rubber wheel roller is done individually and independently of the other wheels or by the sprinkling of the other wheels of the rubber wheel roller.
  • the irrigation of a wheel thus depends only on the temperature of the wheel and the temperature of the soil, in particular that floor portion over which this wheel travels, and the temperature difference between the wheel and the floor or this floor section.
  • the decision as to whether a wheel is sprayed with separating agent is made by the control unit on the basis of the measured values of the temperature sensor, which measures the temperature of the affected wheel. For this, the operator of the rubber wheel roller does not have to give any more control commands.
  • the irrigation is therefore automatically controlled by the control unit according to objectively determined needs of the individual wheel.
  • the temperature sensor must be arranged in such a way that at least the wheels to be measured and optionally the ground are in its measuring field.
  • the temperature sensor may be arranged in the wheel arch of the rubber wheel roller.
  • the temperature sensor should be arranged so that it is spared as possible from the harsh working conditions within the wheel house. It is therefore preferred that the temperature sensor is arranged in the upper half, preferably in the upper third, more preferably in the upper quarter, most preferably in the upper fifth and at best at the upper vertex of a wheel well.
  • the temperature sensor reset in a shaft or a sensor view shaft, which opens into the wheel arch and from which the temperature sensor has a free field of view the wheels to be measured and possibly the ground. Due to the offset of the temperature sensor in a shaft, this is additionally protected against negative environmental influences.
  • a blow-off device can be provided which prevents the temperature sensor, in particular the infrared temperature sensor, from becoming dirty.
  • the solution of the problem initially set also succeeds with a method for controlling a sprinkler of a Gummiradwalze, in particular a Gummiradwalze described above, comprising the steps of: determining the temperature of at least one wheel, in particular the tread of the wheel, by a temperature sensor and controlling the sprinkling of at least a wheel through the sprinkler on the basis of the measured values of the temperature sensor by a control unit.
  • All of the features, advantages and effects outlined above for the rubber wheel roller likewise apply in a figurative sense to the method according to the invention.
  • the corresponding threshold values also correspond to the above-mentioned values. It is therefore only referred to avoid repetition of the above statements.
  • the method comprises at least one of the following steps: determining the temperature of at least two wheels, in particular the running surface of the respective wheel, by means of a temperature sensor; Determining the temperature of all wheels of the respective chassis part, in particular the running surface of the respective wheel, by a temperature sensor; Determining the temperature of all the wheels of the front and rear chassis parts, in particular the running surface of the respective wheel, by a respective temperature sensor for the front chassis part and the rear chassis part; Controlling the sprinkling of wheels arranged on the outside of a working direction separately from the wheel or wheels located between these wheels; Controlling the irrigation of each individual wheel independently of the remaining wheels; Determining the temperature of the soil; Activating the irrigation by the sprinkler when the temperature of the soil is above a threshold and / or the temperature difference between soil and wheel exceeds a predetermined threshold; and deactivating the sprinkler irrigation when the temperature of the soil is below a threshold; and / or deactivating the irrigation by the sprinkler, when the temperature difference between ground and wheel falls below a
