Definitions

  • the invention relates to a construction machine with a mast, a carriage, which is mounted longitudinally displaceable along the mast, a winch and a rope, which is stretched between the carriage and the winch. Furthermore, the invention relates to a method for operating a construction machine, in which a carriage for introducing a body is moved into the ground along a mast, wherein a stretched between the carriage and a winch rope is unwound from the winch.
  • a construction machine of the type mentioned above may be, for example, a pile driver or a drill.
  • Such piling or drilling equipment are used in particular in special civil engineering, for example for driving a sheet pile wall, a pile or a pipe into the ground or for introducing a hole in the ground.
  • the construction machine usually comprises a carrier device to which the mast is pivotally articulated.
  • the carriage is used, for example, to receive the ramming body to be introduced into the ground or a drill drive for driving a drill pipe with a drilling tool. That's how it is EP 22 15 605 A1 A construction machine according to the preamble of claim 1.
  • the stretched between the carriage and the winch rope can be in particular a hoist rope to hold the carriage or lift.
  • the resulting vibrations are transmitted via the rope on optionally existing Seil arrangements- or Seilumlenkrollen and the winch. This can cause considerable wear on the rope, on bearings, on the pulleys or possibly a brake of the winch.
  • the invention has for its object to provide a construction machine and a method for operating a construction machine, which allow the most economical operation and in particular to ensure the lowest possible wear of components of the construction machine.
  • the object is achieved by a construction machine having the features of claim 1 and a method having the features of claim 11.
  • the invention provides that on the rope between the carriage and the winch a rope damping roller is applied, which is pressed by a spring-damping device against the rope.
  • a rope damping roller rests against the rope tensioned between the carriage and the winch and is pressed against the rope by means of a spring-damping device.
  • the invention is based on the recognition that vibrations of the carriage are transmitted longitudinally along the rope, which act on other components of the construction machine, such as bearings, pulleys and winch. These transmitted via the rope vibrations cause wear on the aforementioned components.
  • a first basic idea of the invention is thus to dampen the vibrations transmitted via the cable in its longitudinal direction, so that the vibration transmission to the other components of the construction machine is reduced.
  • Another principle of the invention is to accomplish the vibration damping by means of a spring-loaded damping system.
  • a pulley is pressed by a spring force against the rope and deflects it.
  • the rope length between carriage and winch is increased.
  • the spring-damping device comprises a damping element.
  • Particularly effective rope attenuation can be used in a construction machine, which is designed as a piling device for driving a ramming body into the ground.
  • the carriage is designed to receive the ramming body and a striking device is provided which is arranged for driving the ramming body into the ground on the carriage.
  • the impact device may in particular comprise a percussion hammer, for example a diesel or hydraulic or free-fall hammer. By operation of the hammer, the carriage is pressed down, so that the pile body, such as a sheet pile element, can be driven into the ground.
  • the spring-damping device comprises a spring element and a, in particular separate, damping element.
  • the spring element may for example be a compression spring.
  • the damping element for example a hydraulic, gas or fluid damper or a mechanical damper, serves to prevent or reduce the swinging of the spring.
  • the damping element can be arranged in the interior of the spring. Spring and damping behavior can thus be adjusted specifically and independently of each other and adapted to the forces occurring. It is also possible to provide an integrated spring-damping device, for example in the form of a gas spring.
  • the rope damping roller can be arranged at any point between the carriage and the winch.
  • the rope damping roller it is preferable to arrange the rope damping roller as close as possible to the carriage.
  • the rope damping roller is arranged in the region of a deflection of the rope in an upper region of the mast. Under an upper portion of the mast is to be understood in particular the area of a mast top and / or approximately the height of an upper end point of the travel of the carriage along the mast.
  • the rope which can also be referred to as a hoisting rope, extends upwards from the carriage and is guided via a deflection device to a rear side of the mast, from where it leads to the cable winch.
  • a particularly effective rope attenuation can be achieved in that the rope damping roller between two stationary pulleys is arranged. Especially This can be an effective deflection of the rope through the rope damper role between the two stationary pulleys are effected.
  • the stationary pulleys are deflection rollers of the deflection device, by which the cable is deflected from a front side of the mast, on which the carriage is arranged, to the rear side of the mast.
  • the fixed pulleys are preferably laterally next to each other in an upright position of the mast, that is arranged approximately at the same height.
  • the rope damper roller preferably acts on an approximately horizontal cable section when the mast is in an upright position.
  • the rope damper roller is mounted on a rocker.
  • the rocker which may also be referred to as a rotatable Auslenkarm is preferably pressed by the spring-damping device in the direction of the rope, so that the rope damping roller under the action of a compressive force on the rope and deflects the rope.
  • the rocker is zug- and / or pressurized by the spring-damping device.
  • the rocker and / or the spring-damping device are articulated to a head element of the mast.
  • the head element may, in particular, be a cantilevered arm on which the rocker and / or spring-damping device are mounted.
  • a preassemblable head element together with rocker and / or spring-damping device and optionally Seilumlenkrollen be mounted as a modular unit replaceable on the mast body.
  • An effective rope damping in a comparatively inexpensive construction can be achieved in that the rocker and a fixed pulley, around which the cable is guided, are rotatably mounted about an identical axis of rotation.
  • the bearing pin for the fixed pulley can therefore be used as a kind of bearing pin for the rotatable rocker.
  • the arranged in the immediate vicinity of the fixed pulley rope damping roller causes effective Seilausschung.
  • the winch is designed to permanently bias the rope to prevent a slack rope.
  • a permanent bias of the rope is to be understood in particular the exercise of a tensile force on the rope during operation of the construction machine. This prevents the rope, for example during the piling process or during the drilling process, is too loose and so for example jumps out of its leadership by the pulleys.
  • the cable pretension is in a range between about 200 to 1000 kg, preferably about 500 kg.
  • the invention relates in particular to a method for driving a ramming body into the ground.
  • the body to be introduced into the soil is a piling body which is arranged on the carriage.
  • the carriage is subjected to a stroke.
  • the method can be carried out in particular with a construction machine, as described above.
  • Fig. 1 shows a side view of a construction machine according to the invention 10.
  • the construction machine 10 comprises a carrier vehicle or carrier device 12 with an undercarriage 14 and about a vertical axis of rotation rotatably mounted uppercarriage 16.
  • the undercarriage 14 may have a chassis, such as a crawler track.
  • a mast 20 or broker is pivotally mounted on a pivoting device 24.
  • the pivoting device 24 By means of the pivoting device 24, the mast or brokers relative to the carrier device 12 are horizontally and / or vertically adjusted. Furthermore, it can be provided that the pivoting device 24 allows a folding of the mast 20 in an approximately horizontal transport position.
  • the pivoting device comprises at least one lifting cylinder 26.
  • the mast 20 or broker comprises a base element 54 and a longitudinally displaceably guided sliding element 56.
  • the displacement element 56 By a displacement of the displacement element 56 relative to the base element 54, the effective height of the mast 20 or Gurklers can be changed.
  • the mast 20 On the mast 20 or broker a frame-like carriage 22 is mounted longitudinally displaceable.
  • the mast 20 comprises a guide rail 21 extending along its longitudinal direction for the carriage 22.
  • the carriage 22 is arranged on a front side 18 of the mast 20.
  • the carriage 22 is suspended on a rope 30, which may also be referred to as a hoisting rope.
  • the cable 30 initially extends upwards to a head region 17 of the mast 20 and is guided there by means of a deflection device 34 onto a rear side 19 of the mast 20. From there it runs to a winch 28, which is arranged, for example, as shown, on the carrier device 12. Alternatively, it is also possible that the winch 28 is located on the back of the mast. Between the deflecting device 34 on the mast head and the winch 28, the cable 30 may be guided over one or more pulleys 29.
