Definitions

  • the invention relates to a method of securing a tilting jib crane to secure an angular position of a tilting jib.
  • the invention lies in the field of tilting jib cranes equipped with a tilting winch incorporating a tilting motor driving a drum on which is wound a tilting cable coupled to the tilting boom to drive it in movement angular relative to the horizontal.
  • Two models of crane may be concerned by the invention, namely a luffing jib crane and an automated erection crane.
  • a luffing jib crane as for example described in the document EP 3 466 865 A1 , is a crane comprising a mast at the top of which is pivotally mounted a boom which can be raised and lowered, in other words the boom can pivot at the level of the mast to be raised, possibly to an almost vertical angular position, and be lowered until 'at a horizontal angular position.
  • This boom can be moved in raising and lowering by means of a tilting winch, also called lifting winch, integrating a motor driving a drum on which is wound a tilting cable coupled to the boom, also lifting cable.
  • a self-erecting crane also called a fold-out crane, collapsible crane or transportable crane, is a crane comprising a mast supporting a boom, such a self-erecting crane being configurable between a transport configuration in which the mast and the boom are folded onto themselves or side-by-side, and a working configuration in which the mast and boom are unfolded to perform distribution and load lifting operations.
  • This boom can be moved in raising and lowering, to be able to be folded and unfolded, by means of a tilting winch, also called a retaining winch, integrating a motor driving a drum on which is wound a tilting cable coupled to the boom, also called a retaining cable.
  • the invention concerns the locking of a tilting boom in a desired angular position, in order to maintain or retain it securely and reliably in this angular position, more or less inclined relative to the horizontal.
  • the invention aims to provide a solution for being able to securely and reliably maintain an angular position of a tilting boom, which requires a minimum of human intervention, and which offers simplification of locking/unlocking operations of the tilt winch.
  • the invention firstly proposes to use a locking plate whose locking holes are oblong and arcuate, that is to say are in the shape of an arc of a circle centered on the axis of rotation of the drum, which allows the lock to be engaged in a locking hole with circumferential play which facilitates locking and allows slight rotation of the drum; this circumferential play being dependent on the length of the locking holes and the section of the lock.
  • the invention proposes to automate at least partly the locking, with the first control of the tilt motor which aims to reach the desired angular position, by raising/lowering the tilting boom with a speed parameter limited to the first maximum speed value (which preferably corresponds to the maximum mechanically authorized value) and with a motor torque limited to the first torque limit value; such a first torque limit value being a high value allowing the tilting motor to take up the forces in all the angular positions of the tilting boom.
  • a speed parameter limited to the first maximum speed value which preferably corresponds to the maximum mechanically authorized value
  • a motor torque limited to the first torque limit value such a first torque limit value being a high value allowing the tilting motor to take up the forces in all the angular positions of the tilting boom.
  • the tilt motor's second command aims to slightly lower the tilt boom until the latch abuts against one end of the latch hole. lockdown. This lowering takes place with a speed parameter limited to the second maximum speed value (in other words at low speed), this second maximum speed value being adapted to the distance that can be covered (maximum the length of the locking hole) and the precision necessary for the proper execution of the maneuver.
  • the engine torque is limited to the second torque limit value.
  • the motor torque is still limited to the second torque limit value and the tilt motor continues to force at this second torque limit value, while the speed parameter is zero (in effect , due to the stop of the lock, the drum no longer rotates and the boom no longer lowers).
  • This zero speed phase will last for the predetermined duration (for example a few seconds) before the tilt motor is stopped, and thus the tilt winch is locked.
  • the speed parameter can correspond to the angular speed of movement of the tilting boom, or to another speed or another parameter which depends on this angular speed, such as for example a speed of rotation of the drum, engine speed, etc.
  • validation by an operator that the lock occupies the locking configuration is implemented in order to authorize the second command of the tilt motor.
  • the movement of the lock, between the locking configuration and the release configuration is carried out manually by an operator.
  • detection by a detection system that the lock occupies the locking configuration is implemented in order to authorize the second command of the tilt motor.
  • the movement of the lock, between the locking configuration and the release configuration takes place by means of an actuator.
  • the third command of the tilt motor is followed, before or after moving the lock towards the release configuration, by closing a motor brake associated with the tilt motor.
  • the engine brake is closed, at the end of the release phase, in order to retain the tilting boom thanks to this engine brake, before opening it to carry out an angular movement of the tilting boom, for example to fold it or to reach a new angular position.
  • moving the lock to the release configuration is followed by a fourth command of the tilt motor to move the tilt boom up or down, with a limitation of the speed parameter to the first maximum value of speed and a limitation of the engine torque to the first torque limit value.
  • the tilt boom can again be moved at high speed, that is to say with a clamping of the speed parameter to the first maximum speed value, and with an engine torque adapted to take up the efforts. If applicable, the motor brake is opened to operate the fourth tilt motor command.
  • validation by an operator that the lock occupies the release configuration is implemented in order to authorize the fourth command of the tilt motor.
  • detection by a detection system that the lock occupies the release configuration is implemented in order to authorize the fourth command of the tilt motor.
  • the first command of the tilt motor followed by the forward movement of the lock causes said lock to be substantially in the middle of the locking hole
  • the second control of the tilt motor causes the drum to rotate in a lowering direction in a lowering angular sector substantially equivalent to half of the locking angular sector.
  • the third control of the tilt motor causes the drum to rotate in a raising direction, opposite to the lowering direction, in an angular tilt sector substantially equivalent to half of the locking angular sector .
  • substantially equivalent means exactly equivalent or equivalent to within plus or minus 15% of the length of the locking hole.
  • the tilting jib crane is a luffing jib crane or self-erecting crane.
  • An advantageous use of the invention for an automated assembly crane is to lock and make reliable the retaining of the boom once unfolded, in other words in its working configuration.

    - drittes Ansteuern des Neigungsmotors (30), um den neigbaren Ausleger (12; 22) anzuheben, mit einer Begrenzung des Geschwindigkeitsparameters (PM) auf den zweiten maximalen Geschwindigkeitswert (V2) und einer Begrenzung des Motordrehmoments des Neigungsmotors (30) auf den zweiten Drehmomentgrenzwert (C2);
    - Bewegen des Riegels (42) aus der Verriegelungskonfiguration in die Freigabekonfiguration.
  5. Sicherungsverfahren nach Anspruch 4, wobei dem dritten Ansteuern des Neigungsmotors (30), vor oder nach dem Bewegen des Riegels (42) in die Freigabekonfiguration, ein Schließen einer dem Neigungsmotor (30) zugeordneten Motorbremse folgt.
  6. Sicherungsverfahren nach Anspruch 4 oder 5, wobei dem Bewegen des Riegels (42) in die Freigabekonfiguration ein viertes Ansteuern des Neigungsmotors (30) folgt, um den neigbaren Ausleger (12; 22) anzuheben oder abzusenken, mit einer Begrenzung des Geschwindigkeitsparameters (PM) auf den ersten maximalen Geschwindigkeitswert (V1) und einer Begrenzung des Motordrehmoments auf den ersten Drehmomentgrenzwert (C1).
  7. Sicherungsverfahren nach Anspruch 6, wobei eine Bestätigung durch einen Bediener, dass der Riegel (42) die Freigabekonfiguration einnimmt, zum Einsatz gebracht wird, um das vierte Ansteuern des Neigungsmotors (30) zu gestatten.
  8. Sicherungsverfahren nach Anspruch 6 oder 7, wobei ein Erfassen, durch ein Erfassungssystem, dass der Riegel (42) die Freigabekonfiguration einnimmt, zum Einsatz gebracht wird, um das vierte Ansteuern des Neigungsmotors (30) zu gestatten.
  9. Sicherungsverfahren nach einem der Ansprüche 1 bis 8, wobei in Anbetracht dessen, dass sich die Verriegelungslöcher (41) jeweils über einen gegebenen Verriegelungswinkelsektor erstrecken, das erste Ansteuern des Neigungsmotors (30) gefolgt von der Vorwärtsbewegung des Riegels (42) dazu führen, dass sich der Riegel (42) im Wesentlichen in der Mitte des Verriegelungslochs (41) befindet, und das zweite Ansteuern des Neigungsmotors (30) bewirkt, dass die Trommel (31) in einer Absenkrichtung gemäß einem Absenkwinkelsektor gedreht wird, der im Wesentlichen gleich der Hälfte des Verriegelungswinkelsektors ist.
  10. Sicherungsverfahren nach den Ansprüchen 4 und 9, wobei das dritte Ansteuern des Neigungsmotors (30) bewirkt, dass die Trommel (31) in einer der Absenkrichtung entgegengesetzten Heberichtung gemäß einem Neigungswinkelsektor gedreht wird, der im Wesentlichen gleich der Hälfte des Verriegelungswinkelsektors ist.
  11. Sicherungsverfahren nach einem der vorstehenden Ansprüche, wobei der Kran mit neigbarem Ausleger (1; 2) ein Kran mit anhebbarem Ausleger (2) oder ein selbstaufstellender Kran (1) ist.
  12. Kran mit neigbarem Ausleger (1; 2), der einen neigbaren Ausleger (12; 22) umfasst, der mittels einer Neigungswinde (3), die einen Neigungsmotor (30) einschließt, der eine Trommel (31) antreibt, auf der ein Neigungsseil (35) aufgewickelt ist, das mit dem neigbaren Ausleger (12; 22) gekoppelt ist, angehoben und abgesenkt werden kann, wobei der Kran mit neigbarem Ausleger (1; 2) dadurch gekennzeichnet ist, dass die Trommel (31) drehfest mit einer Verriegelungsplatte (40) verbunden ist, die mit umfangsmäßig verteilten Verriegelungslöchern (41) versehen ist, und er weiter einen Riegel (42) umfasst, der bewegt werden kann zwischen:
    - einer Freigabekonfiguration, bei der er aus der Verriegelungsplatte (40) ausgerückt ist, um die Drehung der Trommel (31) zu gestatten und somit ein Anheben/Absenken des neigbaren Auslegers (12; 22) zu ermöglichen; und
    - einer Verriegelungskonfiguration, bei der er in das Innere eines Verriegelungslochs (41) eingerückt ist, um die Drehung der Trommel (31) zu blockieren und somit die Winkelposition des neigbaren Auslegers (12; 22) zu sichern;
    und wobei die Verriegelungslöcher (41) alle von bogenförmiger, länglicher Form sind, damit der Riegel (42) in der Verriegelungskonfiguration mit einem Umfangsspiel in das Innere eines Verriegelungslochs (41) eingerückt ist;
    und dadurch, dass er ein Messsystem (7), um einen Geschwindigkeitsparameter (PM) zu messen, der für eine Winkelgeschwindigkeit der Bewegung des neigbaren Auslegers (12; 22) beim Anheben oder Absenken repräsentativ ist, und ein Ansteuerungs-Steuersystem (5) umfasst, das mit dem Neigungsmotor (30) und dem Messsystem (7) verbunden ist, wobei das Ansteuerungs-Steuersystem (5) so konfiguriert ist, dass es:
    - eine erste Ansteuerung des Neigungsmotors (30), um den neigbaren Ausleger (12; 22) anzuheben oder abzusenken, mit einer Begrenzung des Geschwindigkeitsparameters (PM) auf einen ersten maximalen Geschwindigkeitswert (V1) und einer Begrenzung eines Motordrehmoments des Neigungsmotors (30) auf einen ersten Drehmomentgrenzwert (C1) ausführt, bis eine gegebene Winkelposition des neigbaren Auslegers (12; 22) erreicht ist, bei der der Riegel (42) auf eines der Verriegelungslöcher (41) der Verriegelungsplatte (40) ausgerichtet ist, wobei der Riegel (42) die Freigabekonfiguration einnimmt;
    - nach einer Vorwärtsbewegung des Riegels (42), um eine Verriegelungskonfiguration einzunehmen, bei der er in das Innere des Verriegelungslochs (41), auf das er ausgerichtet ist, eingerückt ist, Ausführen einer zweiten Ansteuerung des Neigungsmotors (30), um den neigbaren Ausleger (12; 22) abzusenken, mit einer Begrenzung des Geschwindigkeitsparameters (PM) auf einen zweiten maximalen Geschwindigkeitswert (V2), der kleiner ist als der erste maximale Geschwindigkeitswert (V1), und einer Begrenzung des Motordrehmoments des Neigungsmotors (30) auf einen zweiten Drehmomentgrenzwert (C2), der kleiner ist als der erste Drehmomentgrenzwert (C1), bis der Geschwindigkeitsparameter (PM) während einer vorbestimmten Dauer Null ist, um den Neigungsmotor (30) zu stoppen.
  13. Kran mit neigbarem Ausleger (1; 2) nach Anspruch 12, der ein Erfassungssystem (8) umfasst, das erfasst, ob der Riegel (42) die Verriegelungskonfiguration oder die Freigabekonfiguration einnimmt, wobei das Ansteuerungs-/Steuersystem (5) mit dem Erfassungssystem (8) verbunden ist, um eine Information über die vom Riegel (42) eingenommene Konfiguration zu empfangen.
  14. Kran mit neigbarem Ausleger (1; 2) nach einem der Ansprüche 12 und 13, wobei der Kran mit neigbarem Ausleger (1; 2) ein Kran mit anhebbarem Ausleger (2) oder ein selbstaufstellender Kran (1) ist.
