Definitions

  • the invention relates to a self-propelled machine for cutting or milling, in particular a machine for the exploitation of deposits in open-pit mining, for example deposits of coal, ores, minerals, etc.
  • Also referred to as surface miners machines for exploiting deposits in open pit mining have a device for cutting rocks, which has a mechanically or hydraulically driven cutting roller.
  • the road milling machines or recycler have a milling device which has a milling drum.
  • the cutting or milling rollers are equipped with tool holders for receiving the cutting or milling tools.
  • vibrations and vibrations occur in the machines for cutting or milling.
  • the vibrations and vibrations that occur in particular during the mining of extremely hard granite or hard limestone are very strong. The machine operator is directly exposed to these very strong shocks and vibrations.
  • the well-known surface miners have a closed, sealed and soundproof cab with a rotating driver's seat.
  • the cab of the known surface miner is attached to the chassis on which the cutter is arranged. Even with road milling machines or recyclers, the driver's cab is attached to the chassis.
  • a surface miner with a cab attached to the chassis is for example from the EP 0 744 495 A2 or the DE 40 17 107 A1 known.
  • the driver's cab is arranged in the direction of travel on the front of the machine frame, while the driver's station at the out of the DE 40 17 107 A1 known surface miner located in the middle of the machine frame.
  • the DE 10 2005 044 211 A1 describes a self-propelled construction machine, in particular a recycler or a cold milling machine, which has a machine frame, which is supported by a chassis that allows a height adjustment of the machine frame.
  • a control station for a driver is arranged over the front wheels of the chassis.
  • the front and rear wheels of the chassis are fixed by means for height adjustment on the machine frame, so that the machine frame is height adjustable relative to the ground. If the height of the machine frame is adjusted, the height of the control station above the ground also changes.
  • the invention is based on the object to provide a self-propelled machine for cutting or milling with improved ride comfort.
  • the inventive self-propelled machine for cutting or milling is characterized in that the driver's station is not attached to the chassis of the machine.
  • the known machines for cutting or milling have a driver's station arranged on the machine frame, the inventors have recognized that the attachment of the driver's station to the chassis results in the vibrations or vibrations being transmitted to the driver's cab during operation of the machine.
  • the inventors have recognized that it is for the reduction of transmitted to the driver's vibrations or Vibration is advantageous if the driver's cab is arranged with the most direct connection to the ground or as direct connection to the ground.
  • the driver's station is attached to the device for height adjustment of the chassis. It is assumed that the height adjustment devices of the known self-propelled machines for cutting or milling have the crawler or wheel associated components, which are connected to the chassis such that the components are movable when lifting or lowering the chassis and have components that during the height adjustment are not movable.
  • the driver's station is fastened to a component of the height adjustment device that is movably connected to the chassis.
  • the driver's station is rigidly connected to the chassis and therefore participates in the movements of the chassis, but the driver's station is attached to a component of the device for height adjustment, which is movably connected to the chassis.
  • the driver's cab can also be attached to several movably connected to the chassis components.
  • a fixing of the driver's station to the movable component of the height adjustment does not mean that a component of the driver's station must be connected directly to the component of the height adjustment. Rather, a component of the driver's cab can also be connected to the movable component of the height adjustment via another component, for example a carrier or the like, for fastening the driver's station.
  • the basic principle of the machine according to the invention for cutting or milling is to decouple the driver's station from the vibrations or vibrations transmitted to the chassis by the device for cutting or milling or from the vibrations generated by the internal combustion engine for driving the machine.
  • This decoupling succeeds in an advantageous manner in that the device for height adjustment represents a system that is not rigid, but movable the Chain drives or wheels connecting to the chassis.
  • the movable suspension leads to a decoupling of driver's cab and chassis. This ensures that the driver's station, as well as the chassis of the machine quasi “stands firmly on the ground", while the assemblies of the machine with the cutting or milling device and the engine are supported by the chassis in the height adjustable relative to the ground.
  • the means for adjusting the movably connected to the chassis components of the height adjustment cause advantageously an attenuation of the system.
  • the means for adjusting the movable components of the height adjustment are hydraulically and / or pneumatically actuated means, which preferably have a piston / cylinder arrangement.
  • the hydraulically or pneumatically operable piston / cylinder arrangement acts as a shock or vibration damping element due to the elasticity of the tubing and / or the compressibility of the pressure medium to actuate the piston / cylinder assembly. It has been shown that with the attachment of the driver's station to the device for height adjustment, the vibrations and vibrations, which are completely indeterminate in terms of amplitude and frequency, can be damped effectively during operation of the cutting or milling device.
  • a further preferred embodiment of the invention provides that the driver's cab is rotatable about a vertical axis.
  • the driver's cab can preferably be rotated independently of the rotational movement of the crawler tracks or wheels during steering of the machine.
  • the operator's cab is preferably located above the track or wheel and substantially above a point where the track is oscillating suspended or the wheel is rotatably mounted. Then the operator stands or sits just above the crawler track or wheel, with which the track drive or wheel rests firmly on the ground. This arrangement has proven to be optimal in terms of reducing shock or vibration.
  • the rotatable around a vertical axis driver's station can also be arranged next to the axis of rotation.
  • the distance to the axis of rotation can be dimensioned so that the driver's cab can swivel to the outer boundary of the chassis. This has the advantage that the machine operator can better see the area where the milled area turns when the driver's cab is turned.
  • the driver's cab preferably has a rotatable driver's seat, so that the driver can change the viewing direction independently of a rotational movement of the driver's station by turning the driver's seat.
