Definitions
- the invention relates to a method for optimizing a cutting process in road milling machines and to such a road milling machine according to the preamble of claims 1 and 10 respectively.
- the flow rate is set according to the highest demand on the route to be milled.
- the spray nozzles are directed into the milling space parallel to the axis of the milling drum.
- the disadvantages here are that the cooling liquid cannot be metered as required, and that the water tank requires a large amount of space for the water tank, in order to prevent a work interruption from occurring as a result of a necessary water refilling process.
- the invention is therefore based on the object of reducing the space requirement on a road milling machine for water storage and reducing the water consumption to the amount of water actually required.
- the invention advantageously provides that at least one characteristic value representative of the current work output of the milling drum is recorded, and that the quantity of cooling liquid supplied is dependent on the at least one representative characteristic value for the current work output of the milling drum is controlled.
- the invention makes it possible to adapt the quantity of cooling liquid currently supplied to the current work output of the milling drum, so that the total quantity of cooling liquid to be stored can be reduced to a considerable extent, while at the same time adapting to the service life of the milling drum can take place such that the tanks are filled for the coolant only if other maintenance work on the road milling machine, e.g. a tool change, is required. In this way, not only is excessive water consumption prevented, but unnecessary downtimes of the road milling machine are also eliminated.
- a reduction in the required tank size can be achieved by supplying the cooling liquid in accordance with the requirement, as a result of which the overall machine weight can also be reduced. It is therefore sufficient to carry an amount of water with you that is sufficient for one work shift.
- the advantages of the invention can be seen in the reduction of water consumption and tool wear, as well as in the reduction of work interruptions for refueling the water supply or for a tool change.
- a characteristic value representative of the work performance can be formed from the current milling depth and the current feed rate.
- the current measurement or setting values are recorded, whereby the milling depth is generally set and maintained as a constant value and the feed rate can deviate from a preset value.
- the at least one characteristic value representative of the work performed can be formed from the current hydraulic pressure of the travel drive at a constant flow rate or from the current hydraulic pressure and the current flow rate of the hydraulic oil of the travel drive.
- the characteristic value representative of the work performance can consist of the measured torque at constant speed of the milling drum drive.
- a characteristic value representative of the work performance consists of the current hydraulic pressure in the lifting columns of the chassis of the milling machine. If the milling drum has a low milling capacity, a higher pressure is produced in the lifting columns than if the milling capacity is higher, which relieves the load on the chassis due to the forces that occur.
- the at least one characteristic value representative of the work performed can also be determined from the characteristic data available in an electronic motor controller of the drive motor.
- the temperature of a milling tool of the milling drum or several milling tools is recorded as a representative characteristic value for the current work output, is compared with a predetermined target temperature value and the quantity of coolant supplied as a function of the difference between the target temperature value and the measured temperature value is regulated.
- the cooling capacity of the cooling liquid can be regulated as a function of the current working capacity of the milling drum.
- control or regulation of the quantity of coolant is corrected by constant characteristic data that are specific to a machining task, and that the quantity of coolant supplied is read out from a multi-dimensional characteristic diagram as a function of the at least one characteristic value and the specific characteristic data becomes.
- These specific characteristics can consist of the current milling width, a tool constant depending on the type and number of milling tools used, a material constant dependent on the road surfaces being worked and / or the set milling drum speed or a combination of several of the aforementioned characteristics.
- the invention further relates to a milling machine for processing road surfaces with the aforementioned control or regulation of the amount of coolant.
- the cooling device for the milling tools arranged on the milling drum preferably consists of a nozzle arrangement running parallel to the roller axis, which is arranged on the roller box surrounding the milling drum and which is directed towards the milling drum.
- the nozzles arranged in a row next to one another can be designed so that they can be switched off individually and can be controlled individually.
- the spray cones of adjacent spray nozzles at least partially overlap.
- cooling device in which the coolant is directed from the inside of the milling drum onto the milling cutter via spray nozzles arranged on the milling drum.
- the current flow rate for the coolant can be changed by applying a corresponding pressure to the coolant.
- FIG. 1 shows a side milling machine in side view
- FIG. 2 shows a milling drum with a cooling device in the roller box
- FIG. 3 shows a machine control according to the invention, in which a volume flow of the cooling liquid is controlled as a function of the characteristic values representative of the work performance and the characteristic data specific to a machining task ,
- Road milling machines are used for the continuous expansion of road surfaces. These machines are available in different working widths or can be equipped with milling drums of different widths.
- the road milling machines can work with a milling depth of a few millimeters up to a complete ceiling thickness of up to 30 centimeters and more.
- the milling drum can have a different number depending on the application and / or a different type of carbide-tipped picks.
- fine milling the road surface is milled only slightly in order to obtain a level, non-slip road that is no longer processed.
- up to 400 chisels and more are used per running meter of working width.
- milling drums 4 which have only 80 chisels per running meter of working width and less.
- the milling tool 12 used for example round shank chisels, is also matched to the respective application by its shape and the type of hard metal used.
- the round shank chisels are to be understood as wearing parts and the variety of different carbide types and chisel shapes serve to improve the service life.
- the milling tools 12 are cooled with water.
- FIG. 1 shows a known road milling machine 1 with a machine frame 2 in which a milling drum 4 is rotatably mounted.
- the machine frame 2 is supported by a chassis with a plurality of trolleys 8, which are connected to the machine frame 2 via lifting columns 10.
- the milled material of the road surfaces reaches a first conveyor device 20 with a conveyor belt, which is arranged in a shaft of the machine frame 2 and transfers the milled material to a second conveyor device 22 with a further conveyor belt.
- the current feed rate can be measured with the aid of a sensor device 17.
- the machine frame also carries a tank 14 for a coolant.
- the coolant preferably water
- the coolant preferably water
- in the tank 14 can be fed to a cooling device 10 via a pump 15 in order to spray the water during operation via a spray ramp running parallel to the roller axis of the milling drum 4 onto the milling tools arranged on the milling drum 4.
- the water is conveyed out of the tank 14 by means of a pressure pump, with which the pump pressure can be variably adjusted to set the instantaneous quantity of coolant.
- the spray ramp on the roller box 5 surrounding the milling drum 4 consists of several spray nozzles arranged next to one another, it being possible for some of the spray nozzles to be shut down in accordance with the milling width of the milling drum 4 used. For this purpose, it is provided that the spray nozzles can be activated in order to be able to be switched on or off.
- the machine controller 16 of the milling machine 1 controls or regulates the volume flow of the cooling liquid according to the exemplary embodiment in FIG. 3 as a function of at least one representative characteristic value for the current work performance of the milling drum 4.
