Definitions

  • the invention relates to a crane control.
  • a crane control in the context of this invention is to be understood to mean a control for load cranes which controls the movements of the crane, such as the movement of a crane carriage along a crane jib or the lifting of a load on the crane by means of a crane winch.
  • a crane control can also be designed to record and evaluate process-specific parameters.
  • Cranes for lifting heavy loads are well known and have been used for a very long time. Cranes are found in a variety of applications, e.g. As a free-standing scaffolding cranes on construction sites, as integrated in halls factory cranes for lifting, for example, container loads in port areas or the like. For the purposes of this invention cranes are all those constructions to understand that can raise heavy loads and move or move with motor drive.
  • Such cranes already have by default controls on which the various possible movements within the crane are coordinated to a desired To perform the operation.
  • motors are controlled by such controls for moving a crane bridge or a crane jib, motors for moving a crane truck on a crane boom or a crane bridge, motors for pivoting the crane boom and motors for rolling a lifting rope with load hook and load on it.
  • control pear In such known controls typically sits an electromechanical, more rarely an electronic control element, which in a high-altitude part of the crane, such as the crane boom, the crane bridge or the like is arranged.
  • a so-called control pear is provided in many cases, can be entered from the operator on the ground command signals for operating the crane in the controller.
  • This control pear like other controls, is typically connected to the central controller via a cable connection through which individual signals are fed to the central controller.
  • radio link which is typically unidirectional and directed only from the control pear to the central control unit. Over this radio link individual tracks are represented by their own frequency ranges.
  • Such radio links have the advantage that a cable can be omitted, but they do not change the basic architecture of the well-known controls.
  • the basic idea of the invention is to construct the crane control as a whole in a modular manner with at least two control modules.
  • the control modules are to be connected to one another via a full-value, bidirectional, wireless data connection in the sense of a bus connection.
  • a wireless connection allows for real data exchange and not just radio control over certain line channels.
  • the wireless data connection according to the invention can be configured by means of suitable software, without making a cumbersome wiring, as it must ultimately be given in the known radio devices (correct wiring of the radio transmitter or radio receiver with the respective modules).
  • a presently preferred example of such a full-fledged bidirectional wireless data connection is a Bluetooth connection (see claim 7).
  • other wireless data connections are possible, as long as they provide a full-value bus line.
  • the crane control can be constructed in a modular manner depending on the particular needs, for example, standard control modules can be used.
  • the crane control system can be easily added by adding another module and Use of appropriate software extensible, in particular it is possible, for example, to provide interfaces with which the controller can be connected to an intranet or to the Internet (see claim 8).
  • a central control computer arranged outside the crane (see claim 9), which may also be connected to the controls of several cranes via the wireless data connections provided according to the invention. In this way, for example, in a complex storage or assembly hall, the control of multiple cranes can be realized via a single central computer, without limiting the local operation and the possibility of a targeted intervention in the workflow of a particular crane.
  • the preferred use of the Bluetooth technology is particularly distinguished, since this can be realized very susceptible to interference by external interference. This is especially important to avoid that control signals sent to a crane inadvertently reach another crane causing unwanted and dangerous malfunctions.
  • one of the at least two control modules is an input / output module and a second module is a computer module with a microcomputer.
  • the input / output module may be an operator-handheld portable device similar to a "control pear" of known crane controls (claim 3).
  • a microcomputer can also be arranged (claim 4).
  • the crane control further comprise state sensors which are connected to at least one of the modules for the evaluation of the data (claim 5).
  • state sensors are connected to at least one of the modules for the evaluation of the data (claim 5).
  • the determined data of these sensors are displayed via channels of an operator that are separate from the actual crane control.
  • the inventive advantage of the advantageous development lies in the fact that the signals of such sensors (possibly with the interposition of a preamplifier) are introduced into the control where they centrally mitverarbeitet and either for the control of the workflow (for example, the signals of Endanschlagsensoren) are used or but can be displayed to an operator.
  • These signals of the sensors or the data calculated therefrom by the controller can be transmitted via the inventively provided, full-value, bidirectional, wireless data connection.
  • the crane control has an electronic storage medium in order to record operating data of the crane or the like.
  • a storage medium e.g. a "log book" of the crane are led to monitor operating conditions or detect malfunctions.
  • a solution as described in claim 11 allows a particularly robust and low-wear supply of a control module with the required energy.
  • crane controls consuming cable strands on the one hand for Supply are laid on the other for data exchange, now suffices a pure sliding contact for the voltage or power supply.
  • the solution of a sliding contact is much less susceptible than towed cables, which are subject to the risk of cable breaks, for example, due to frequent position or position changes.
  • the invention means a considerable flexibility in the construction of a crane control and is also connected to conventional crane controls with classic wiring with significant savings in material and assembly time.
  • a 20 tonne crane with 30 meter span by replacing a classic, cabled control by a crane control according to the invention about 200 to 300 kg of copper lines and the associated rail systems for attaching the lines and about 2 days assembly work can be saved.
  • the subject of the invention is also a crane equipped with a control as described above.
  • Fig. 1 is a schematic plan view of a crane girder 1 with a crane truck 2 running thereon.
  • the crane truck 2 runs with sliding contacts, not shown here, via a guide rail 4 laterally mounted in the region of a rail 3 of the crane girder 1.
  • a control 10 according to the invention (see Fig. 2) is integrated in the crane.
  • the controller 10 has three modules, a first control module 11 with a microcomputer on the crane truck 2, a second control module 12 laterally on the crane girder 1 and a third control module 13, which serves as an input / output module and realized as a so-called "tax pear".
  • the control module 13 is thus a hand-held device, which can be used by an operator, for example, below the crane girder 1 on a hall floor operator for controlling the crane.
  • the individual control modules 11, 12 and 13 are connected to each other via a Bluetooth data connection, which is indicated by corresponding radio symbols 14.
  • control module 13 the control bulb
  • a separate microcomputer is integrated, which performs the main processor power of the controller.
  • the serving as input elements switch or button are queried and forwarded corresponding control instructions for the other control modules 11 and 12.
  • the calculation for the coordination of the individual crane drives takes place here, which are ultimately controlled by the control modules 11 and 12.
  • a display 15 for example in the form of an LCD display, arranged, via which an operator individual operating conditions or -kenntone can be displayed.
  • values determined by sensors connected to the control such as, for example, the weight of a load suspended on the crane, can be displayed, which data was transmitted in the control module 13 via the Bluetooth connection 14.
  • FIG. 2 the controller 10 according to the invention is shown once again schematically.
  • the control modules shown in FIG. 1 with 11 and 12 are summarized.
  • sensors such as crossing limit switch 17, Spindelendschalter 18 and laser sensors 19 are connected.
  • strain gauges arranged in the region of the load hook can be connected with their signals to the data acquisition.
  • the signals of the sensors 17, 18, 19 and other sensors can be supplied to the control or the control modules 11 and 12, either directly or via preamplified amplifiers.
  • the control modules 11 to 12 accomplish the control of the motors.
  • a parameterization or standardization is carried out to keep the system open, also with regard to the cooperation with other elements with other basic software.
  • Bluetooth service routines are connected to provide the data to be exchanged rendered in a Bluetooth-enabled manner.
  • the designated “13 control bulb” contains according to this scheme, for example, touch sensors 20, button 21 and a code sensor 22. These are used for data acquisition and are correspondingly connected in software in this control module 13.
  • this control module 13 contains a data storage. The actual data processing takes place in the control module 13, ie the main microprocessor is arranged in this control module 13. Not shown in this illustration is also included in this control module display.
  • a separate level of Bluetooth service routines is included, which provides for the preparation of the data to be exchanged for the Bluetooth standard.
  • Fig. 2 are shown as part of the controller 10 even external controls, which are generally designated 16.
  • the Bluetooth connection can be used to connect additional computers to the controller.
  • a connection to a network is shown, via which workstation 23, a PLC / server 24 as well as an input to the Internet 25 can be connected.
  • control 10 basically represents an open system which can be equipped with further hardware modules as well as expanded via software solutions.
