Definitions

  • the invention relates to a crane according to the preamble of claim 1 and to a vehicle with such a crane.
  • Cranes of the generic type with a crane control which is configured in an operating mode to carry out coordinate control of the arm system are known in the prior art.
  • the individual actuators of the arm system are controlled by the crane control in such a way that the user controls the behavior of the crane tip of the arm system instead of the individual actuators himself.
  • coordinate controls There are known designs of coordinate controls in which the crane is essentially controlled by the user with only two operating elements (e.g. joysticks), one for pivoting the crane column and one for performing a horizontal movement and a vertical movement of the crane tip.
  • the arm system can have more degrees of freedom than are at least necessary for the positioning and orientation of the crane tip in space.
  • the crane pillar of a generic crane is via a structurally specified crane pillar Swivel area mounted pivotably and has a degree of freedom due to its pivotable mounting.
  • the main arm is pivotably mounted on the crane column over a structurally predetermined pivoting range of the main arm and has a degree of freedom due to its pivotable mounting.
  • the articulated arm is pivotably mounted on the main arm over a structurally predetermined articulated arm pivoting range and has a degree of freedom due to its pivotable mounting.
  • the at least one push arm is mounted in the articulated arm so as to be displaceable over a structurally predetermined push area and has a degree of freedom due to its displaceable mounting.
  • the arm system of a generic crane accordingly has four degrees of freedom. In the prior art, such arm systems are known, for example, as redundant or overdetermined manipulators.
  • a so-called backward transformation or kinematic reversal is usually carried out by a processor or a computer unit of the crane control after the specification of a desired path of the crane tip, i.e. after the user has issued a corresponding control command (for example, movement of the crane tip in Cartesian coordinates) , from which the control commands suitable for the desired path for controlling the actuators of the arm system result (for example movement of the arm system along the degrees of freedom of the joints).
  • the backward transformation for generating control commands for the arm system must take place with the inclusion of optimization criteria (such as so-called cost functions with weighting matrices) and possibly with approximations and is associated with a high computational effort.
  • optimization criteria such as so-called cost functions with weighting matrices
  • the object of the invention is to provide a crane with a crane control which is configured in an operating mode to carry out coordinate control of the arm system, as well as a vehicle with such a crane in which the operator can influence the movement of the arm system in order to avoid unforeseen movements and in which the complexity of the calculation of the reverse transformation is reduced.
  • the crane control has a user interface, the user interface having at least one function that can be selected by a user and by which at least one of the degrees of freedom can be or is restricted in the coordinate control operating mode.
  • the movements of the arm system can be more predictable for the user by restricting at least one of the degrees of freedom by the at least one function that can be selected by a user. For example, by selecting a corresponding function, a user can specifically restrict and / or switch off degrees of freedom of movement of the arm system which he does not want to have involved in the movement of the arm system in the coordinate control operating mode.
  • the movements of the arm system can be specifically adapted to the planned lifting process.
  • the user can thus be given an opportunity to interact with the crane, whereby the user can influence the operation of the crane.
  • the user can thereby be given the option of making a selection of the arms of the arm system that are involved in the coordinate control.
  • a user can also be given the option of preferring or prioritizing different combinations of arms of the arm system involved in the coordinate control.
  • the arm system additionally has a second articulated arm, which is pivotably mounted on the push arm over a structurally predetermined second articulated arm pivoting range and has a degree of freedom due to its pivotable mounting, and which preferably comprises at least one second push arm which is mounted displaceably in the second articulated arm over a structurally predetermined second push arm push area and has a degree of freedom due to its displaceable mounting.
  • the second articulated arm expands the space for possible positioning of the crane tip and is often referred to as the so-called “fly jib”.
  • the arm system additionally has at least one main arm push arm, which is slidably mounted in the main arm over a structurally predetermined pushing area and has a degree of freedom due to its slidable mounting.
  • the main arm can be designed to be telescopic through the at least one main arm push arm.
  • At least one additional device in the form of an implement and / or a Arm extension, preferably a static arm extension that can optionally be arranged at a predeterminable angle, is arranged.
  • the coordinate control it is basically not a problem to take into account the geometric data of additional devices or attachments in the calculation. To do this, the coordinate control only needs to be supplied with information about an additional device attached to the arm system (e.g. information on the scope of functions, dimensions, angle positions) so that this information can be included in the calculation.
  • information about an additional device attached to the arm system e.g. information on the scope of functions, dimensions, angle positions
  • information preferably information on the scope of functions and / or dimensions and / or angular positions, for the at least one additional device can be transferred to the crane control via the user interface, the information being selectable from a database stored in a memory of the crane control and / or can be entered via the user interface, preferably via a setting mask.
  • information on an additional device that is already stored in the crane control can be selected via a menu or information can be entered by the user via a setting mask.
  • a security query can be provided to ensure that the crane is set up. It can thus be provided that the user has to confirm the set-up status of the crane via the user interface by selecting a corresponding function of the user interface.
  • the crane control is designed to carry out a coordinate control of the crane tip or a predetermined or predeterminable point of the arm system or a predetermined or predeterminable point supported by the arm system.
  • coordinate control of the crane tip is usually carried out.
  • any other point of the arm system or a point supported by the arm system can be used for which coordinate control is carried out. So a winch could be arranged on the arm system and a Coordinate control could be performed in relation to the attachment point of the cable winch on the arm system or in relation to the load hook on the cable end of the cable winch.
  • the coordinate control no longer relates to the crane tip itself, but rather directly regulates the position of the load at the end of the cable.
  • the change from a coordinate control of the crane tip to a coordinate control of a predefined or predefinable point of the arm system or a predefined or predefinable point supported by the arm system can be detected by the crane control and suggested to the operator, who can or must confirm this change. It can also be provided that this change can be activated by the operator by selecting a corresponding function of the user interface.
  • a suitable restriction is the restriction of degrees of freedom of the arm system.
  • At least one degree of freedom of the arm system can be or is limited by the at least one function that can be selected by the user in order to eliminate or reduce an overdetermination of the arm system.
  • the degree of freedom of the rotatable crane pillar to maintain the pivotability of the crane pillar is excluded from the set of restrictable or restricted degrees of freedom. This is particularly useful when executing coordinate controls in which the crane is controlled by the user with two operating elements (eg joysticks), one of the two operating elements for pivoting the crane column and the other operating element is used to perform a horizontal movement and a vertical movement of the crane tip.
  • two operating elements eg joysticks
  • Maintaining the pivotability of the crane column can be desirable, for example, if this degree of freedom of movement of the arm system is not redundant.
  • a degree of freedom of the arm system can or is limited by the at least one function that can be selected by the user, or that all degrees of freedom of the arm system can or are limited up to two degrees of freedom.
  • the restriction of one degree of freedom is sufficient to remove or reduce an overdetermination of the arm system, since exactly two degrees of freedom remain after the restriction of one degree of freedom to move the arm system horizontally and vertically. If the arm system includes additional arms (e.g.
  • the restriction of all degrees of freedom of the arm system up to two degrees of freedom is sufficient to remove or reduce an overdetermination of the arm system, since after such a restriction of the degrees of freedom exactly two degrees of freedom remain to make a horizontal movement and a vertical movement of the arm system.
  • the coordinate-controlled movements of the arm system are carried out with only two arms or crane sections or degrees of freedom, which means that these movements are clearly determined and easier for the user to understand.
  • restricting a degree or degrees of freedom of an undesirable arm can prevent unpredictable movements of the arm system.
  • the crane control in the coordinate control operating mode is configured to use an arm selection in the form of a subset of the arms of the arm system to perform the coordinate control of the arm system, the crane control having at least one operating profile in which at least two arm selections are stored in a predefined or specifiable sequence from a higher priority to a lower priority or are continuously determined, and the crane control is designed to use and control the arm selections stored in at least one operating profile according to their prioritization to carry out the coordinate control of the arm system, wherein the at least one operating profile can be selected through the at least one function that can be selected by the user.
  • An ongoing determination can take place during operation as a function of the current position of the arm system or the suitability of an arm selection for the flub movement carried out or to be carried out.
  • each of the at least two arm selections consists of two arms of the arm system.
  • One of the operating profiles can, for example, be a so-called standard prioritization that is always used when no other operating profile is specifically or specifically selected.

If the movement of the arm system desired by the user with the arm selection with the highest priority, i.e. prioritization 1 (main arm and articulated arm), is possible, this arm selection is always used to carry out the coordinate control of the arm system. If one of the arms of the arm selection reaches the end position or is otherwise blocked, the arm selection with the next lower priority is used. Should the arm selection with the prioritization 1 become available again in the course of the movement of the arm system (i.e. that the movement desired by the user would be possible again with this arm selection), the currently used arm selection is still used in order to constantly switch between the To avoid coordinate control used arm selections.

  • the crane is moved in a coordinate-controlled manner using the arm selections of the operating profile according to Table 4, and as the arm system moves, the main arm leaves its target angle and is at an angle of 50 °. Subsequently, the arm selection changes due to an end position or a restart of the movement.
  • the two arm selections that include the main arm i.e. the arm selection with prioritization 2 and the arm selection with prioritization 3 are then evaluated by the crane control to determine whether the target angle of the main arm can be approached again with the current user specification.
