Definitions

  • the invention relates to a floor cutting device according to the preamble of claim 1.
  • Such floor cutting devices have long been known as floor saws, cutters or floor cutters and are used to cut open asphalt or concrete floors.
  • the figure shows such a known floor cutting device, which will be explained later in detail.
  • the operator can usually estimate the rotational speed of the cutting shaft only on the basis of the noise development of the cutting motor driving the cutting shaft. This is usually difficult if the operator wears prescribed hearing protection or if there are other noise generators in the immediate vicinity of the work site.
  • the operator With a machine feed, the operator also lacks the valuable feedback on the feed force that he has with manual cutting machines Feed can feel directly by the force applied to the handle.
  • the invention is therefore based on the object of specifying a floor cutting device with which an optimum feed rate can always be ensured.
  • a ground cutting device has a power detection device and a control device coupled to the power detection device.
  • the power detecting means is for detecting an actual value for the power of the cutting tool or the power of the cutting motor proportional to the power of the cutting tool.
  • the power detection device can also determine a parameter that is dependent on one of the aforementioned services or otherwise corresponds to it and therefore also has significance.
  • the actual value is supplied to the control device, the actual value with a predetermined, z. B. already compared in the factory during assembly stored target value. Depending on a deviation from the actual and desired value, the control device influences the feed rate.
  • the feed speed is no longer manually - whether by pushing the floor cutter by the operator or by manually adjusting the feed speed - but automatically adjusted by the control device.
  • the power of the cutting shaft or the power of the cutting tool (cutting disc) or the main drive motor (cutting motor) is the control variable.
  • the power detection device has a rotational speed detection device for detecting an actual value for the rotational speed of the cutting tool or the rotational speed of the cutting motor that is proportional to the rotational speed of the cutting tool.
  • the speed detection device can also determine a parameter which is dependent on one of the aforementioned rotational speeds or corresponds to one of the rotational speeds and thus also has significance.
  • the actual value of the speed is used in this embodiment instead of the actual value for the power and used as a control variable for the control device.
  • the speed is a criterion corresponding to the physical power.
  • the speed of the cutting shaft normally decreases or increases.
  • the corresponding speed change is determined by the speed detection device and evaluated in the control device.
  • the control device can then reduce or increase the feed rate until the cutting shaft again reaches the predetermined target speed.
  • the cutting motor has a speed control and / or limiting device for holding a predetermined speed whose control activity can be evaluated by the power detection device for determining the actual value for the power of the cutting motor.
  • the cutting motor is an internal combustion engine whose ignition timing, ie the time interval of the ignitions, as a criterion for the engine speed and thus the rotational speed of the cutting shaft and the cutting tool is used.
  • the speed detection device determines the actual value for the speed due to the ignition cycle, which is passed on to the control device.
  • the cutting motor is an electric motor. It may be advantageous if the current power consumption is evaluated as a criterion for the speed of the cutting motor.
  • control unit setpoint can be set at the factory. In another embodiment of the invention, however, it is possible for the operator to vary the set point due to variable operating parameters, namely, the material of the cuttings to be processed, the performance of the cutting tool, the depth of cut, or the rated speed of the cutting motor.
  • the control device controls an additionally provided for the cutting motor, belonging to the feed device feed motor, which moves the chassis relative to the ground.
  • control device can be switched on or off, so that the operator still has the option to manually push the floor cutting device or to set the feed rate by hand to a value desired by him.
  • the automatic adjustment of the feed speed reduces the risk of incorrect operation, especially by unknowing operators. Furthermore, previously required manual control units can be dispensed with.
  • the automatic control ensures an economically and ecologically favorable operation of the floor cutting device.
  • the single figure shows a serving as a floor cutter joint cutter.
  • the cutting motor 2 is a gasoline engine, the fuel from a Tank 3 refers.
  • the cutting motor 2 drives via a cutting shaft, not shown, serving as a cutting tool cutting disc 4, which saws in a known manner the soil to be processed. In the cutting disc 4, it may be z. B. act a diamond blade.
  • a rear axle with two rear wheels 6 is arranged, of which only one is visible in the figure. Accordingly, at the front end of the chassis 1, a front axle 7 is also arranged with two wheels 8.
  • the feed motor for the rear wheels 6 serving electric motor can, for. B. be powered by the driven by the cutting motor 2 alternator with energy.
  • the operator can move the joint cutter with the aid of a handle 9 over the ground.
  • the operator may change the feed rate as desired, taking into account, in particular, the effective feed force (indicative of the resistance encountered by the cutter disk 4 during cutting) and the audible engine speed.
  • a speed detection device and a Control device provided, which make it possible that the feed rate is set and changed automatically.
  • the controller evaluates the speed of the cutting shaft or a dependent of this speed, for example, proportional parameters. Therefore, the speed of the cutting disc 4 or the engine speed are also suitable as further parameters.
  • the engine speed can be at an internal combustion engine z. B. be determined by determining the ignition timing.
  • the generation of the spark already provides an electrical signal that can be evaluated by the speed detection device in a simple manner and is a reliable criterion for the engine speed.
  • the joint cutter has an electric motor as a cutting motor, z. B.
  • the evaluation of the current consumption can be used as a criterion for determining the engine speed.
  • a target value is stored at the factory, which should be adhered to during operation of the floor cutting device. To get the best possible result, the engine should always run at full load. A speed control of the motor is possible, but not mandatory.
  • the control device controls the feed motor belonging to the feed and reduces the feed rate generated by the rear wheels 6. As a result, the cutting forces acting on the cutting disc 4 are reduced, so that the rotational speed of the cutting disc 4 can recover and moves again in the range of the target rotational speed.
  • the control device increases the feed rate, which results in an increase of the cutting forces and thus a braking of the cutting disc 4.
  • control device it is possible to keep the joint cutter always at the optimum operating point, on the one hand to avoid overloading the cutting disc 4 and the cutting motor 2 and on the other hand to allow effective speedy work.
  • the feed can be switched on or off in a known manner in order to avoid an unwanted start of the ground cutting device.
  • control device is switched off to allow the operator to either slide the joint cutter by hand or - as in the prior art - to enter a constant value for the feed rate, which is then observed regardless of the actual loads acting.
  • the embodiment described above uses the speed as an easily determinable and evaluable criterion for the power to be detected.
  • other parameters may be used that are a criterion for the performance of the cutting motor 2 or the cutting disc 4.
