Definitions

  • the invention relates to a construction machine with a mast and a lifting element, which can be moved up and down along the mast with a hoist rope, which can be actuated by means of two cable winches, according to the preamble of claim 1.

  • a winch with a hoist rope and a lifting element can be provided thereon.
  • the hoisting rope is connected at one end to the winch and can be wound up and unwound therefrom.
  • On the lifting element up and down to moving tool or load is arranged.
  • the ends of the hoisting rope are each connected to a winch.
  • the two winch drives of the winches are operated synchronously. For moving the tool or the load up and down, moreover, approximately the same torques are to be provided on both cable winches by the winch drives.
  • An advantage of such a method of moving a tool or a load up and down is that not all the weight of the tool or the load has to be moved by a single winch. Rather, the weight of the two attached to the construction machine or its mast winches can be moved together.
  • Construction machines with two winches for moving a tool or a load up and down allow safe working, especially with heavy tools or loads.
  • Such construction machines may, for example, be a diaphragm wall grab which has a mast, a carrier unit and a mobile undercarriage.

  • a controller is provided, with which the first winch, which is designed as a freefall winch, for lowering the simultaneously operable by the two hoist hoist rope in a free fall mode is switched, while the second winch is operated non-positively.
  • a winch can be understood as a free-fall winch, which can freely release or unroll a hoist rope.
  • the freewheeling release or unwinding can be determined by the gravitational force of a Tool or a load can be generated, which can be connected to the hoisting rope via a lifting element.
  • a free-fall mode can be understood as a mode in which a hoisting rope is not substantially braked during a free-running lowering operation or operated non-positively in any other way.
  • a basic idea of the invention is that for lowering the hoist rope the two winches are asynchronous, that is, with different unwinding speeds, operable to allow the lowering of the hoisting rope with a lifting element, tool and / or a load with free fall speed.
  • the second winch can be designed as a force-operated winch, which allows a controlled lowering. This is a combined operation of a freefall winch and a hoist winch.
  • it has been recognized that such asynchronous operation of two winches enables a hoist rope to be reliably operated when lowered at a high free-fall speed. It is also possible to combine two freefall winches.
  • the free-fall speed can be understood to mean a speed which corresponds almost to the speed of the free-falling mass of the lifting element, the tool and / or the load during lowering.

  • a rope bottle can represent any rope deflection.
  • the rope bottle can consist of two opposite flanges, between which a profiled roller is arranged on a bearing, over which a hoisting rope can be deflected.
  • the two flanges can be arranged hinged.
  • the hoisting rope is formed from at least two ropes coupled or connected to one another.
  • the two cables coupled or connected together may be connected with cable connectors or coupled with cable couplers.
  • the two winches are connected via the at least two ropes coupled or connected to one another.

  • the cable connector on the opposite side of the free-fall, that is on the side of the non-positive hoist winch can be arranged.
  • a further advantageous embodiment variant of the construction machine according to the invention is given by the fact that the free fall winds has a free-fall, with which the free-fall can be opened for free-running lowering of the hoisting rope and the free-running hoist rope is braked by closing the free-fall brake again.
  • the freefall brake When the freefall brake is closed, that is to say, the freefall winch can be operated in a non-positive mode.

  • the cable sections of the hoist rope are preferably evenly distributed to the first and second winch drum. There may be an equal number of windings on each winch drum when the winch drums are provided with the same diameter.
  • asynchronous unwinding of the hoisting rope in a free fall can also be provided to handle the hoist of both wind drums in a non-positive operation of both winches with different unwinding speeds, which also different Hubseiltren can be handled when lowering.
  • the winches can be operated with correspondingly different speeds so that when reaching the starting position, the hoist rope evenly distributed on both wind drums is present.
  • an asynchronous operation of the two winches or the two winch drums in the sense of the invention is to be understood as meaning that the two winches or winch drums open or close the hoisting rope at different speeds.
  • Different speeds may consist of two of the following speeds: free-fall speed, holding speed (zero speed), a first arbitrary speed between the free-fall speed and the holding speed, and a second arbitrary speed between the free-falling speed and the holding speed other than the first arbitrary speed
  • the free fall speed is determined by the gravity of the lifting element or an attached tool or a load.
  • the speed may in particular be a speed which corresponds approximately to the free-fall speed, but is slightly lower to prevent the presence of a slack rope when lowering the hoist rope.

  • sensors can also serve to determine when lowering the lifting element, for example, in a hole in the ground, the lowering position, for example, below the terrain surface.
  • Such sensors may preferably be provided on the winches and determine the lengths of the unwound hoisting rope from both winches and in particular evaluate them in real time.
