Definitions

  • the present invention relates to a device for controlling the position of a steering gear, in particular of a ship.
  • control devices which comprise two double-acting actuating cylinders, connected to the ends of a rod or wick cross member of the apparatus and connected to means for supplying fluid under pressure, the operation of which is controlled by means for controlling the position of the device at a set position.
  • the means for supplying fluid to the actuating cylinders comprise one or more fluid pumps and it is necessary to increase the fluid switching in the supply circuits of the cylinders for reasons of rapid reconfiguration of the together for example after a breakdown.
  • this increases the complexity of the circuits and the risk of leaks.
  • this type of steering gear is increasingly involved in stabilizing and damping the movements, for example of the ship which is subjected to wave movements, for example from the sea.
  • documents FR-A-2 058 953 and US-A-3 741 073 are known, devices for controlling the position of any device such as an aircraft control surface, comprising actuating jacks connected to means for supplying pressurized fluid, the operation of which is controlled by means of slaving to a set position.
  • the object of the invention is therefore to solve these problems by proposing a device for controlling the position of a steering gear which is simple, reliable and which makes it possible to ensure optimal stabilization of the position of this gear.
  • the subject of the invention is a device for controlling the position of a steering device of a ship according to claim 1.
  • a device according to the invention for controlling the position of a steering gear for example of a ship, comprises two actuating cylinders 1 and 2 double effect whose piston rods are connected to the ends of a bar or wick cross member of the apparatus, designated by the general reference 3 in these figures.
  • This steering device has a conventional structure with a bar or wick crosspiece to orient the rudder (not shown) in a desired position.
  • the actuating cylinders 1 and 2 are connected to means for supplying pressurized fluid designated under the general reference 4 in FIG. 1, the operation of which is controlled by means 5 for controlling the position of the apparatus at a setpoint position.
  • These control means have a structure of known type and include, for example, a conventional PID type regulator.
  • the means 4 for supplying the cylinders with pressurized fluid comprise a supply group associated with each actuating cylinder 1 and 2, these groups being designated by the references 6 and 7, respectively.
  • These groups have known structures and include, for example, hydraulic pumps whose operation is controlled by the output of the servo means 5.
  • control device also comprises means 8 for balancing the pressures of the fluid supplying the actuating cylinders at the outlet of these groups in order to balance the control of the actuating cylinders and stabilize the device in position. .
  • these balancing means 8 advantageously comprise two jacks with double balancing effect, designated by the general references 9 and 10, mounted in opposition and whose piston rods are integral in translation.
  • Each of these balancing cylinders 9 and 10 is connected in parallel to one of the operating cylinders 1 and 2 respectively, so as to be supplied with pressurized fluid at the same time as these.
  • the device according to the invention also comprises a linear sensor 11 for positioning the rods of the balancing jacks, the output of which is connected to means 12 for regulating the operation of at least one of the supply groups.
  • cylinder and in the particular case, group 6, to balance the control of the actuating cylinders and stabilize the position of the steering gear by acting on the outlet pressure of this group.
  • cylinders 1 and 2 are supplied by groups 6 and 7 depending on the value position setpoint entered in the regulator and the actual position of the drill bit. Note that these positions are entered and measured respectively by any means known per se.
  • the supply of the cylinders 1 and 2 being done by means of separate and separate pumps, it is necessary to provide means for balancing the pressures and output flows of these groups to obtain good stabilization in position of the device. to govern.
  • This is achieved by means of the balancing means comprising the balancing jacks 9 and 10 connected in parallel on the jacks 1 and 2.
  • the balancing means comprising the balancing jacks 9 and 10 connected in parallel on the jacks 1 and 2.
  • the displacement of these pistons causes a displacement of the rods thereof and the displacement of these rods is measured by the position sensor 11.
  • the output thereof is used to regulate the operation of one of the supply groups through regulator 12.
  • the device according to the invention makes it possible to compensate for any imbalance in addition to the pressures of supply fluid to the actuating cylinders of the bar or wick cross member to obtain optimal stabilization of the steering gear.
  • the drive member 14 is movably mounted on a guide rod 16.
