Definitions

  • the invention relates to a construction machine according to claim 1 and to a method for operating a construction machine according to claim 10.
  • tilting moments can occur on the construction machines.
  • Such tilting moments can be caused statically, for example by spreading loads, but also dynamically, for example by centrifugal forces.
  • the object of the invention is to provide a construction machine, which has a particularly high operating range, a particularly large variety of applications and a particularly high performance with a particularly high operating reliability, in particular with regard to the stability, a particularly high working radius.
  • a construction machine is provided with a carrier unit, an actuating unit, which is adjustable relative to the carrier unit, at least one sensor for detecting status data of the construction machine, and a computer unit, by which at least based on the detected state data an adjustment range of the actuating unit can be determined, in which the actuating unit is adjustable at a predetermined tilting safety of the construction machine.
  • the invention is based on the recognition that when adjusting a heavy actuator unit relative to the carrier unit, which carries the actuator unit, center of gravity shifts can occur, which are associated with corresponding variable tilting moments.
  • a computer unit determines an adjustment range in which the actuating unit can be moved safely relative to its carrier unit.
  • the safe setting range can be distinguished, for example, by the fact that a predetermined tilting safety factor is maintained in its interior.
  • corresponding characteristic fields or tables can be stored in the evaluation unit, for example.
  • the determination of the adjustment range is carried out depending on condition data of the construction machine, that is, the computer unit can take into account in the sense of an overall consideration that the tendency to tilt is determined not only by the projection of the actuator, but is also influenced by other factors, such as the load on the Actuator or the dynamic state of the construction machine. Therefore, the state data may, for example, be data relating to the diameter of a drill pipe held by the actuation unit, which again influences the tilting moment via the associated mass of the drill pipe.
  • the construction machine may in particular be an earth boring device.
  • the operating unit may be, for example, the drill drive for a Erdbohrtechnikmaschine, and the carrier unit of the undercarriage of the drill.
  • the position of the actuating unit within the adjustment range can be determined by the computer unit, and a signal can be emitted when a limit of the adjustment range is reached.
  • the actual position of the actuating unit is related to the calculated adjustment range by the computer unit, so that it can be directly assessed whether tilt-safe operation is present or whether there is a danger of tipping.
  • the signal which is emitted when the limit of the adjustment range is reached may be, for example, an operator signal, that is, for example, an acoustic or optical signal that can be perceived by an operator of the construction machine.
  • the operator is thus able to detect the approach to a dangerous tilt area, so that the operator can take appropriate countermeasures.
  • a control signal for the actuating unit can be emitted as a signal.
  • the computer unit can automatically hold the actuator in the safe adjustment range, so that a particularly reliable operation is given.
  • the carrier unit has a chassis.
  • the carrier unit may be an undercarriage of the construction machine.
  • the actuating unit has at least one civil engineering tool, in particular a drilling tool.
  • the actuating unit can be designed, for example, as a rotary drilling drive and / or vibrating drilling drive.
  • the actuating unit is advantageous for the actuating unit to be pivotable relative to the carrier unit about a vertical axis and / or radially adjustable relative to the vertical axis.
  • Under the vertical axis can be understood in particular an at least approximately vertical axis.
  • the actuating unit embodied as a drill drive is arranged on a mast which is radially adjustable relative to an uppercarriage, which in turn is pivotable relative to the carrier unit formed as an undercarriage.
  • the transducer according to the invention can detect the state data by physical measurement. It may also be advantageous for at least one sensor to be provided which records status data entered manually by the operator become. For example, it can be provided that the operator receives a selection menu of possible drill pipe diameters, for example 880 mm or 1300 mm, or the drill pipe diameter is automatically detected. According to the input, the computer unit then determines different adjustment ranges, wherein the adjustment range for larger drill pipe diameter and thus heavier drill pipe will be regularly smaller than for a smaller diameter. If a pickup is provided for detecting manually entered status data, it is advantageous that the computer unit has a memory device for storing the manually entered data. This will provide documentation to help you determine if the data entered was correct in the event of possible failure.
  • a further preferred embodiment of the invention consists in that an operator-actuatable handling assistance switching device is provided, which is in signal communication with the computer unit, wherein the computer unit is adapted to modify the adjustment range as a function of a switching state of the handling assistance switching device.
  • This embodiment takes into account that different operating modes frequently occur on the construction machine, which require different overturning safety considerations. For example, in a drilling operation of a drill often additional forces on the drilling tool, which can increase the tendency to tilt, or it is working with angled mast, which can also increase the tendency to tilt. Therefore, a limited adjustment range can be determined in the drilling operation by the computer unit.
  • the handling assistance switching device can be realized, for example, via a switch or via a touchscreen, at which the operator specifies whether a working operation, in particular drilling operation, or whether a handling operation is provided.
  • the handling assistance switching device expediently has a memory device which is set up to store the choice of the operator on the handling assistance switching device.
  • the extension of the adjustment range in handling mode requires that other operating parameters of the construction machine and the associated overturning moments be limited.
  • the extended adjustment range in handling mode can only be justified if the winch forces of a main winch, an auxiliary winch or a feed winch are below an allowable limit.
  • the handling assistance switching device may have a display which indicates to the operator the limits of these operating parameters when the handling mode is selected on the handling assistance switching device. For example, the permissible winch forces can be displayed on a display.
  • a limiting unit which is set up to limit at least one operating parameter of the construction machine as a function of the switching state of the handling assistance switching device.
  • the critical operating parameters can be automatically limited when the handling mode is selected on the handling assistance switching device.
  • the at least one operating parameter which is limited and / or displayed to the operator, may in particular be wind tensile forces. Accordingly, it may be provided that the limiter unit reduces the torque of a feed winch and shuts off an auxiliary winch when handling mode is selected.
  • the handling assistance switching device comprises a protective device which prevents the effect of an actuation of the handling assistance switching device when at least one operating parameter of the construction machine is outside a predetermined range.
  • the effect of the operation of the handling assistance switching device can be prevented if at least one operating parameter is atypical for the handling operation, and thus an extension of the adjustment range is not justified.
  • the at least one operating parameter of the construction machine may in particular to act at a superstructure speed and / or a mast tilt.
  • Construction machines often have a superstructure, which is arranged rotatably about a vertical axis on the carrier unit, and on which a mast is arranged, which carries the actuating unit. If the superstructure together with the actuating unit is rotated about the vertical axis relative to the carrier unit, then centrifugal forces can occur which increase the tendency to tilt dynamically. Therefore, a manual or automatic limitation of the superstructure speed may be advantageous.
  • the mast inclination of the mast relative to the superstructure can influence the tendency to tilt, so that a limitation of the mast tilt with regard to the tipping safety can be advantageous.
  • the at least one operating parameter whose limits are displayed, which is limited by means of the limiting unit and / or which is taken into account by the protective device, may also be a rotation angle of the superstructure relative to the undercarriage, since a mobile undercarriage is often not in all spatial directions equal tip over.
  • the condition data on the basis of which the adjustment range is determined by the computer unit, may in particular be a weight force on the actuating unit.
  • the tube length can be taken into account on the actuator, because the longer the drill pipe hanging on the actuator, the greater is often the tendency to tilt.
  • At least one sensor is provided for detecting a position of a mast support jib. Because the position of the mast support arm, which connects the mast with the superstructure, is often a measure of the radial position of the mast and thus the position of the actuating unit relative to the superstructure, and thus determines the overturning moment.
  • At least one sensor for detecting a rotational angle of the upper carriage is provided. Because the carrier unit is often not equal tilt stability in all directions. Thus, the upper carriage rotation angle of the upper carriage relative to the carrier unit, in particular about a vertical axis, also gives indications of overturning safety.
  • At least one sensor is provided for detecting a tensile and / or compressive force in a feed system for a carriage.
  • a carriage feed system may, in particular, be understood as a system which shifts the actuating unit in the vertical direction relative to the mast. The tensile and / or compressive force acting there can likewise influence the tilting moment.
  • At least one sensor is provided for detecting a tensile force in a main cable.
  • a corresponding main rope may carry a drill pipe extending on the actuator unit.
  • At least one sensor is provided for detecting a tensile force in an auxiliary rope.
  • an auxiliary rope which can be used for example in the assembly of a drill pipe, can also cause tilting moments.
  • a further embodiment is that at least one sensor is provided for detecting at least one inlet angle of the auxiliary rope, because the inlet angle can also influence the tilting moment caused by the auxiliary rope.
  • the entry angle is determined in two spatial levels.
  • a further preferred embodiment of the invention consists in that at least one sensor is provided for detecting at least one angle of inclination of the carrier unit.
  • the inclination angle is determined in two spatial levels. The angle of inclination of the undercarriage can also influence the tilting moments.
  • At least one receptacle is provided for detecting at least one inclination angle of the mast.
  • the tilt angle of the mast can be understood in particular the inclination angle of the mast relative to the superstructure. This angle can also influence the tilting moments.
  • the inclination angle is determined in two spatial levels.
  • At least one sensor is provided for detecting a cable end position of the auxiliary cable. This can be taken into account that the load attached to the auxiliary rope may under certain circumstances be subject to oscillating movements, which also contribute to the overturning moment.
  • the sensor for detecting a cable end position of the auxiliary cable can be designed in particular as a sensor for detecting the Abspulwinkels a drum for the auxiliary rope.
  • At least one sensor is provided for detecting a wind speed. This takes into account that wind loads can also have a tilting moment increasing effect.
  • At least one sensor is provided for detecting a rotational speed of the upper carriage.
  • At least one sensor is provided for detecting a cable end position of a feed cable. Because the position of the feed rope points to the position of the actuator and thus in turn to the relevant for the tilt safety center of gravity.
  • At least one sensor is provided for detecting a cable end position of the main cable. By detecting the end position of the main rope center of gravity coordinates can be determined, which determine the tipping moment.
  • a further preferred embodiment of the invention is that a display device is provided, with which the adjustment can be displayed together with the current position of the actuator unit, and that the display device is adapted to represent the adjustment and the current position in a common position sketch.
