Definitions

  • the invention relates to a dredger with a floating body, on which a scaffold is arranged, which is provided with a lifting mechanism, which has two grippers with its own opening and closing mechanism, e.g. drives a motor-hydraulic gripper in an opposite movement.
  • Dredgers are known in which the gripper's own weight is eliminated by the arrangement of counterweights. The disadvantage, however, is that the counterweight has to be moved up and down mechanically. Furthermore, moving the counterweights does not bring any additional funding capacity. Dredgers are also known (DE 36 16 287 A1), in which two grippers are driven in the opposite direction to lifting and lowering movements. These grabs are operated by mechanically coupled hoists, but this is not functional if there are different excavator depths and thus there is no need to compensate for the dead load in some areas. This means that the drives must be designed as usual.
  • the object of the invention is to design a dredger of the type mentioned at the outset in such a way that a different excavator depth resulting from the different slope tendency and possibly slipping material is compensated for by turning off the grab weight.
  • At least one driven traction sheave is provided as the hoist, that the hoist rope is guided over the traction sheave and the grippers provided with rope pulleys and that the hoist rope ends each have one Balancing winches are held, which produce the rope compensation for different excavator depths.
  • An advantageous embodiment provides that the upper end point of a gripper can be detected via limit switches or light barriers.
  • the lower end point of the gripper can be detected by means of initiators, load cells, pressure cells, strain gauges, standstill motors and the like.
  • the lifting rope be guided over rope deflection rollers in order to increase the distance between the grippers.
  • An advantageous embodiment provides that the traction sheave is arranged on the floating body, while the compensating winches and the rope deflection rollers are attached to the scaffold.
  • Another embodiment provides that a movable chute or a bunker wagon can be brought under the grippers in the upper end position.
  • the invention has the advantage that the gripper's own weight is excluded by the two oppositely connected grippers, so that a higher delivery rate can be achieved. With the drive power used for one gripper, two grippers can now be driven. In addition, the energy saving increases by eliminating the dead load. Instead of the previous complex hoists, a simple drive via one or more traction sheaves is possible. The use of such traction sheaves results in significantly less rope wear. According to the invention can be simple means to achieve a depth compensation to adapt to different excavator depths.
  • the drive shown in the drawings is arranged on a dredger with a floating body, namely on a scaffold 1 at a corresponding height above the floating body.
  • a traction sheave 2 which is driven by a motor 3 with a gear 4, serves as the main drive.
  • a lifting rope 5 runs over this traction sheave 2, which is designed as a rope or pulley, on which two grippers 6, 7 are suspended from rope pulleys 8.
  • Each rope end is attached to a balancing winch 9 and 10 and can be wound up.
  • the two grippers 6, 7 are driven in opposite directions by the traction sheave 2.
  • Each balancing winch is provided with a drive motor 11 with gear 12.
  • FIG. 3 shows an embodiment with two traction sheaves 2.
  • Each hoisting rope 5 is guided to the compensating winches 9, 10 via the gripper suspension 8. If several traction sheaves 2 are used, the coefficient of friction and braking is increased, the traction sheaves can be dimensioned smaller and also the hoist rope diameter.
  • Fig. 4 shows the position of the grippers 6, 7 in which the gripper 6 has the upper end point 13, i.e. has not yet reached the emptying position.
  • the gripper 7, however, has the lower end point 14, i.e. not fully reached the bottom.
  • the leveling winch 10 now has the task of compensating for the respective change in the excavator depth, i.e. the compensating winch 10 raises the gripper 7 until the gripper 6 has reached the upper end point 13 with the aid of the traction sheave drive. Only then does the opened gripper 7 touch down on the floor 14 with the help of the winch 10 now working in opposite directions and begins to grip.
  • the gripper 7 has already reached the upper end point 13, while the open gripper 6 located in the water is still arranged above the seabed 14.
  • the balancing winch 9 gives way to the hoist rope until the gripper 6 sits on the ground and begins to grip.
  • the gripper 7 is buried in the lake bed 15.
  • the gripper 6 is located at its upper end point 13.
  • the drive of the traction sheave 2 can be equipped for pure gripper lifting operation, ie with a drive power that is precisely necessary for the low and normal power requirement.
  • the balancing winch 10 can be used to pull out the stuck gripper 7, which then operates at a low speed and correspondingly lower installed power. 5, the gripper 7 is pulled out with the aid of the compensating winch 10.
  • the drive of the traction sheave 2 can also be used to increase the breakaway force.
  • the gripper 7 is spilled and the gripper 6 is supported at the upper end point 13 by means of a holder 16.
  • the gripper 7 can thus be recovered via two compensating winches 9, 10.
  • the drive of the traction sheave 2 can also be used here to increase the breakaway force.
  • the gripper 7 can be dredged with the help of the other gripper 6 by the gripper 6 operating at a slow speed via the compensating winch 9.
  • FIG. 9 shows a possibility for controlling the excavator sequence, the gripper 7 being in the upper end position 13 and being switched off via a rocker 17 with a touch limit switch 18.
  • a light barrier can also be provided.
  • the other gripper 6 is controlled via a depth shutdown when the lower end point is reached, for example an initiator 19 being provided.
  • the shutdown can also be carried out by other known devices, such as load cells, pressure cells, strain gauges or a standstill motor. Shutdown devices such as those described in DE-OS 35 36 472 are also suitable are.
  • the upper and lower shutdown devices, each shown only in the drawings, are provided for both grippers 6, 7.
  • the gripper 6 has not yet reached the seabed 14, so that there is no message from the depth shutdown.
  • the balancing winch 9 therefore releases as much hoist rope 5 until the gripper 6 is seated and can carry out the digging process.
  • the gripper 6 already touches the sea floor 14 while the gripper 7 has not yet reached its upper end position 13.
  • the depth shutdown of the balancing winch 9 gives the command to catch up with the gripper 6 until the gripper 7 has reached its end position.
  • the gripper 6 can then initiate the excavation process.
  • the entire drive technology can be carried out with the well-known slip ring rotor system in combination with a programmable logic controller, with regulated or unregulated DC motors or with frequency-controlled squirrel-cage motors.
  • the latter two systems can also be equipped with computers, so that a fine-tuned control of all movements is guaranteed.
  • sounder systems for function and control can also be integrated into the electrical control system.
  • FIG. 11 For conveying the excavated gravel, it is expedient (FIG. 11) to arrange a movable chute 20 below the filled gripper 7, which brings the material to a material silo 21.
  • This silo 21 can be followed by a drainage device 22, which feeds the material to a material conveyor 23.
  • a movable bunker wagon 24 can be located below the filled gripper 7 be arranged (Fig. 12) or the material can be loaded directly onto slides 25 in ships 26 (Fig. 13).
  • FIG 14 shows an embodiment in which the two grippers 6, 7 are arranged at a greater distance from one another.
  • the traction sheave drive 2, 3, 4 is arranged on a trestle frame 27 and the hoisting rope 5 is guided over additional rope deflection rollers 28, which results in a correspondingly greater distance with excavator points 29 and 30 between the two grippers 6, 7.
  • the traction sheave drive 2, 3, 4 is arranged on the floating body 31, while the compensating winches 9, 10 are attached to the frame 1.
  • rope deflection rollers 28 are again provided, which are arranged on the frame 1.
