Definitions

  • the invention relates to a construction machine for working floor surfaces, with a milling drum, on the surface of which a plurality of chisel holders are arranged, a chisel, in particular a round chisel, being exchangeably received in a chisel holder of the chisel holder.
  • Such a construction machine designed as a road milling machine is known from DE 39 03 482 A1.
  • Road surfaces can be milled off with the road milling machines.
  • the chisels wear continuously while the machine is in use. When the chisels have reached a certain state of wear, they must be replaced. For this it is necessary that a worker goes into the area of the milling drum and there the chisels from the chisel holders casts. When driving out the chisel, the worker uses a special driving mandrel and a hammer. Injuries can result. Handling in the narrowed milling drum area is extremely laborious and requires great care to minimize the risk of danger. After a chisel has been removed from its chisel holder, new unsworn chisels must be inserted into the
  • Chisel holders can be used. Replacing the chisels is a very tedious and time-consuming job.
  • This object is achieved in that a tool changing device is assigned to the milling drum, and in that the tool changing device disassembles and / or assembles the chisel or chisels from the chisel holder.
  • an interchangeable tool which automatically disassembles the worn chisel and / or mounts an unshielded chisel in the chisel holder receptacle of the chisel holder.
  • the tool changing device is preferably a mechanical tool device. Which is arranged inside or outside the milling drum. In the technical design of the tool changing device, different concepts can be implemented depending on the application. a) The tool changer will be positioned to the chisel. b) The chisel will be positioned to the tool changer. c) The tool changer and the chisel are positioned to each other.
  • the tool changing device has at least one tool changer that can be assigned to the individual bit holders or groups of bit holders by means of an actuating unit. It is also conceivable that a single tool changer is assigned to all chisels or chisel holders. This then disassembles or assembles the chisel at the same time. In an alternative embodiment of the invention it can also be provided that each tool holder is assigned a tool changer of the tool changing device and that the tool changer is firmly connected to the tool holder. The tool changers can be connected to one another via a common control. Using this control, a machine operator can, for example, selectively change individual chisels, groups of chisels or all chisels at the same time.
  • a conceivable variant of the invention can be characterized in that the tool changing device introduces at least one dynamic impulse into the milling drum, part of the milling drum, the chisel holder or a group of chisel holders against the dismantling direction of the chisel. Accordingly generates an impulse from the tool changing device which, due to the inertia of the chisel, introduces an expulsion force into the chisel.
  • the pulse can be built up, for example, by an oscillation generated in the milling drum. It is also conceivable that one or more vibration devices are provided. Another possibility is that a pulse shaper is used on the milling drum.
  • the milling drum is assigned a stop which is provided with a stop surface pointing into the working movement device, and that a pulse shaper applies a force acting against the working movement direction to the stop surface.
  • the pulse shaper can be a mallet that acts on this stop surface with its weight.
  • the design of the tool changing device can be such that the chisel is positioned in relation to the tool changer (see b) and c) above).
  • the chisel can be positioned, for example, with an adjustment device that positions the milling drum relative to the tool changer.
  • this can be done in such a way that the milling drum is coupled to a drive motor of the construction machine via a drive train, the adjusting device having an auxiliary drive that can be coupled to the drive train that raises the milling drum by a predetermined or selectable state Angle of rotation rotated, the torque of the auxiliary drive being higher than the moment of inertia of the milling drum and of the part of the drive train which is moved with the milling drum when the drive motor is switched off or decoupled.
  • the predetermined position pattern of the chisel can be used and stored in a control system.
  • the tool design can be such that the actuating unit positions the at least one tool changer relative to the milling drum. The tool changer and the milling drum are then brought into position with respect to one another.
  • tool changers are fixedly arranged on the machine side.
  • the chisels are then assigned to them as a result of a rotation of the milling drum.
  • the tool changer can be designed in such a way that it engages the chisel positively and / or non-positively and disassembles it from the chisel holder or assembles it into it.
  • the tool change can be further automated if it is provided that the tool changing device conveys the dismantled chisels directly or via a conveying device into a container or that a separating device is assigned to the tool changing device, and that the separating device feeds chisels from a storage unit to the tool changing device.
  • Optimal utilization of the tool life can be achieved if it is provided that the milling drum is assigned a detection device that continuously, at intervals or by default, checks the wear condition of the chisel or a part of the chisel or an individual chisel, and that the detection device initiates or signals a tool change when a predetermined wear condition is reached.
  • the wear detection can, for example, be designed such that at least one signal recording unit of the detection device is at least one Work process directly or indirectly involved machine component is assigned that the signal recording unit detects an operating state of the machine component, and that the signal recording unit determines the wear state via a signal processing arrangement.
