Definitions

  • the invention relates to articulated arms for the transfer (loading or unloading of a ship for example) of fluid products, of the general type comprising a base, an internal tube and an external tube articulated together, and a counterweight system, the internal tube pivoting on the base, and the external tube carrying an elbow assembly and emergency disconnection device ,. part of this assembly remaining integral with the ship in emergency disconnection.
  • a problem encountered in this area is that of the difficulty of connecting the marine loading arms to the ship when they are unbalanced in normal operation. Another problem is that of the marine loading arms which, when they are over-balanced on the articulated assembly or under-balanced (the arm being in empty or full emergency disconnection) may tend to approach the ship with risk of shock. Another problem is that of the curve described by the end of the part of the elbow-emergency disconnection device assembly remaining integral with the external tube, when the internal tube rises, in particular in the case where the angle between the outer tube and the inner tube remains constant or varies very slowly.
  • Oil loading arms are known with two counterweights comprising a deformable parallelogram, one of the short sides of this parallelogram being in the extension of the external arm and the other small side being articulated on the base with a beam, the internal arm constituting the other large side parallel to the beam.
  • An arrow comprises a movable part and a fixed part.
  • This fixed part carries a movable balancing mass longitudinally and a mechanical transmission is established so as to link a movement, but in opposite directions, the mobile part of the boom and the balancing mass with respect to the fixed part. of this arrow.
  • the beam is associated with an attitude control system comprising a pair of pendulums and a pair of valves and sensor means attached to the beam to determine the attitude of the outer arm and acting on actuators of the inner arm and of beam swivel control.
  • an attitude control system comprising a pair of pendulums and a pair of valves and sensor means attached to the beam to determine the attitude of the outer arm and acting on actuators of the inner arm and of beam swivel control.
  • an oil loading arm comprising a balancing system designed so as to neutralize the vertical movement of the arm regardless of the position of the arm.
  • This system comprises a single counterweight guided so as to effect a vertical movement on a rod.
  • the counterweight is suspended by two cables.
  • the invention relates to a loading arm with two counterweights but without parallelogram and adopts an essentially hydraulic solution to make one of the counterweights mobile.
  • said overpressure is used to control the opening of a sequence valve, which opening triggers the hydraulic actuation of said mobile counterweight.
  • the invention also relates to a hydromechanical arrangement implementing the above method and, according to one embodiment of this arrangement, the hydraulically movable counterweight is a slider.
  • the hydraulically movable counterweight is mounted in a rocker.
  • the invention is applied to an articulated arm for transferring fluid products, in particular petroleum products, between a quay installation (Q) and a ship (N) for example .
  • the articulated arm comprises a base (1) and, pivotally mounted on this base, using two elbows (2) and (3) and two bearings (4) and (5), an internal tube (6) at one end of which is articulated an external tube (7).
  • a first pivoting takes place around a vertical axis Z-Z of the base and a second pivoting occurs around a horizontal axis X-X.
  • the outer tube (7) carries at its end an assembly (13) with elbows (14) and emergency disconnection device (15) for the connection with the ship. It should be noted that part of this assembly remains on the vessel during an emergency disconnection.
  • At least one counterweight (16) hydraulically movable is provided on the beam (8) for the rear extension of the internal tube (6) of the articulated arm.
  • the hydraulically movable counterweight (16) is produced in the form of a cursor capable of moving on slides (17) fixed by spacers (18) both on the elbow (3) of the internal tube (6 ) and on the beam (8).
  • the counterweight-cursor carries rollers (19) facilitating its movement on the slides (17). It is divided into two masses (16A) and (16B) connected by a plate (20) on which is articulated in (21) the rod (22) of a control cylinder (23) fixed on the internal tube (6) .
  • Another cylinder (28), whatever its location, allows the control of the external tube (7). Embodiments of the location of this external tube control device will be described later.
  • Pressing the cylinder (32) of the emergency disconnection device locks the cylinder of the external tube (7) in position. Locking is done using normal controls.
  • the external tube (7) is blocked by the pressurization of the jack (32) of the emergency disconnection device.
  • the normal commands allow the locking position to be set.
  • the flow regulator (R2) installed on the chamber (B) of the jack (24) of the internal tube (6) allows a fixed flow; therefore the pressure in this chamber is higher at the set pressure of the sequence valve (VS) which opens.
  • the pressurized oil coming from the chamber ( B ) controls the pilot valve (VP) which changes state (line P l) the oil flow passing through the regulator (R2) is directed towards the line (Pl).
  • This line also connected to the output of the sequence valve (VS) then feeds through a direction selector (SI) the chamber (B) of the jack (23) for controlling the mobile counterweight (16).
  • SI direction selector
  • the oil escapes from the chamber (B) to the tank through the solenoid valve (EVl).
  • the mobile counterweight (16) rises, the imbalance decreases as well as the pressure in the chamber (B) of the jack (24) of the internal tube (6).
  • the value of this pressure is lower than the setting of the sequence valve (VS) it closes, but the ascent of the internal tube continues slowly.
  • the piloted valve (VP) remains in the piloted position, the pressure coming from the chamber (B) of the jack is in communication with the piloting chamber (line Pl) through a flow limiter (L3); this line always feeds the ascent of the counterweight to an equilibrium position.
  • the change of state of the piloted valve (VP) is carried out automatically when the operator resumes control of the arm.
  • the pressure is applied to the chamber (A) of the jack (24) of the internal tube (raising of the arm) line (A) of the selector-valve (SV1) the oil under pressure controls the opening of a piloted valve (C P ) which drains the line (Pl) towards the reservoir (R) of the hydraulic power unit.
  • the valve pilot orifice (VP) is no longer under pressure; it returns to the normal operating position using its return spring.
  • the chamber (A) of the jack (24) of the internal tube is in communication with the reservoir of the hydraulic unit through the piloted valve ( VP ).
  • Calibrated valves (CT) installed between the chambers (A) and (B) of the cylinder (24) of the internal tube allow the intercommunication of these two chambers when the pressure reaches a value greater than that of the setting of these valves, in the event of a malfunction of the devices described above.
  • the curve (El) shows the movement of the end (O) of the outer tube (7) after disconnection, the position of said outer tube being blocked relative to the inner tube (6).
  • the curve (E2) shows the movement of the same end (O) of the external tube (7) after disconnection, the inclination of the external tube remaining constant relative to the vertical axis ZZ of the base, hence the clearance of the tube external to the ship.
  • the actuator (28) for controlling the external arm acts on a movable pulley (33) connected by a cable (34) to a pulley (35) fixed relative to the base.
  • the cylinder body (28) is mounted oscillating on the wheel (9). The detail of this mounting of the jack is shown in FIG. 8.
  • the body of the jack (28) is always mounted oscillating on the wheel (9) and the rod of this jack is connected by a yoke to the pivot (9A) of the wheel on which the pulley is fixed. (33).
  • the cylinder body (28) is mounted oscillating on the beam (8) while its rod is connected by a yoke to the pivot (9A).
  • two jacks (28) for controlling the external tube (7) are arranged on each of the strands of a cable (36) connecting a pulley (37) fixed to the external tube (7) and a pulley (38) attached to the base.
  • the body of the actuator (28) for controlling the external tube (7) is mounted oscillating on the base (1) while the end of its rod is articulated at (39) to a pulley (40) crazy climb on the base.
  • the pulley (40) is connected by a cable (41) to a pulley (42) fixed to the external tube.
  • the movable counterweight (16) is found to be rocked on the beam (8) of the rear extension of the internal tube (6) but it is always controlled, and in the same way, by the jack (23).
  • the counterweight (16) is mounted on a branch (43A) of a bent lever pivoting on the beam (8) around an axis (44), the other branch (43B) of the lever being also articulated to the rod of the control cylinder (23).
  • the counterweight (16) is shown in this figure in two different tilting positions corresponding substantially to the positions (Pl) and (P2) of the other embodiment.
  • the actuator (23) for controlling the movable counterweight-slider (16) can be fixed on the rear beam (8) instead of being fixed on the internal tube.
