Definitions

  • the invention relates to a ramming device for ramming pile material into a ground, with a carrier device, a mast which is attached to the carrier device, a basic slide which can be moved and driven linearly along a guide of the mast, and an impact unit which is connected to the base slide is connected and guided along the mast, wherein the impact unit is designed to generate impact pulses for driving in the pile, according to the preamble of claim 1.
  • the invention further relates to a method for ramming piling material into a ground, wherein a carrier device with a mast is provided, on which a base slide with a striking unit is moved along a guide of the mast, the striking unit generating impact pulses with which the piling material is driven is rammed into the ground, according to the preamble of claim 11.
  • Such ramming devices have long been known and are used, for example, for driving piles, steel girders or planks.
  • These ramming devices have an impact unit, also called a hammer, which is used either hanging on a rope, riding freely or guided on a mast.
  • the percussion unit is pulled up along the mast by means of a rope of a cable winch, the pile being introduced at a receptacle on the underside of the percussion unit.
  • the pile is hammered or pressed into the ground.
  • the pile is driven into the soil by a certain amount.
  • the depth of penetration can change with the individual pile-driving strokes.
  • the invention has for its object to provide a piling apparatus and a method for driving piles into the ground, with which in a simple structure, an efficient driving operation can be achieved.
  • the ramming device according to the invention is characterized in that the impact unit is connected to the base slide at a variable distance via a connecting rope which is held in a tensioned state by means of a tensioning device.
  • a basic idea of the invention is to provide a ramming device with a mast, along which a movable base slide is linearly guided.
  • the percussion unit is not attached directly to the base slide, but is connected to the base slide at a distance from it via a connecting cable.
  • the connecting rope allows a flexible, changing distance between the basic slide and the percussion unit during a ramming process. This flexible distance thus enables the impact unit to be moved efficiently and reliably with the pile-driven material in accordance with the travel path caused by an impact.
  • the flexible cable connection prevents impact pulses from being noticeably transmitted to the base carriage and thus the mast and the carrier device, so that the overall construction is protected. This increases the overall life of the pile driver.
  • the impact unit is guided directly on the mast, preferably along the same linear guide that is provided for the basic slide.
  • the storage of the impact unit directly on the mast also reduces the overall risk of the pile driver tipping over.
  • a tensioning device is provided, by means of which the connecting rope is kept in a tensioned state during the ramming process. This prevents slack rope from forming when the base slide approaches the percussion unit when following it during the ramming process, which rope could be damaged between the base slide and the percussion unit.
  • the tensioning direction can be designed in any way with corresponding flexible or elastic elements, for example with hydraulic tensioning pistons.
  • the tensioning device has at least one tensioning spring.
  • the at least one tension spring is preferably a tension spring. The use of a tension spring allows an overall cost-effective and compact structure.
  • the tensioning device has at least one rocker to which the connecting cable is attached and which is pivotable and spring-loaded is articulated to the basic slide.
  • the connecting rope can be moved transversely to the axial direction and thus laterally outwards when the striking unit and base slide approach. In this way, the connecting rope is protected from damage and a particularly good approach between the base slide and the striking unit guided along the mast is possible.
  • a further advantageous embodiment of the invention consists in that a control unit is provided which controls a tracking of the basic slide to the impact unit when it is driven in.
  • the control unit is designed in particular in such a way that the basic slide is tracked to the impact unit in such a way that a minimum distance between the basic slide and impact unit always remains during the entire ramming process and there is no direct contact. This avoids the transmission of unwanted vibrations to the base slide and the overall construction.
  • control unit can be designed in such a way that the base slide and the impact unit are not so far apart when being hammered that the connecting cable is completely stretched. This protects the connecting rope and also prevents the transmission of unwanted vibrations to the base slide. A stretched connecting rope is only given if, after the ramming process has been completed, the basic slide is moved upwards again along the mast and the impact unit attached via the connecting rope is pulled along.
  • At least one sensor is arranged on the clamping device for detecting a measured value, which represents a measure of the distance between the base slide and impact unit, and that the control unit adjusts depending on the at least one recorded measured value controls. If the specified upper and lower distance values between the basic slide and the impact unit are exceeded or not reached, the control unit can reliably track the distance.
  • the at least one sensor can be designed for direct or indirect measurement of the distance value.
  • An advantageous embodiment is after a A further development of the invention is that a sensor is designed to detect an angular position of the rocker. An angular position on a rotatable machine part can be carried out in a simple and reliable manner. Since the dimensions of the rocker and the connecting cable attached to it are known, reliable information on the axial distance between the base slide and the impact unit can be determined in the control unit on the basis of the angular position.
  • At least one sensor is designed to detect a distance and / or an approach.
  • Such distance or proximity sensors can work optically, in particular with a laser, inductively, capacitively or with a resistance measurement, for example. A reliable distance value can thus also be determined in a relatively simple manner.
  • the impact unit is designed as a hydraulic hammer unit or a diesel hammer unit.
  • the percussion unit has at least one displaceable percussion piston arranged in a housing.
  • the percussion piston is raised by hydraulic energy, while in the case of a diesel hammer unit, it is raised by a combustion or explosion process. With both hammer units, desired impact pulses can be achieved in a particularly robust manner.
  • the mast of the piling device can be designed in any way. It is particularly preferred that the mast is designed as a leader, in particular as a telescopic leader.
  • the leader is designed in two parts, a mast part which can be moved thereon is arranged on a rigid mast part.
  • the base slide and the striking unit can be mounted so as to be movable along a guide.
  • a telescopic leader is advantageous because of the adjustability of the mast for bringing in particularly long pile material.
  • the carrier device has an undercarriage on which an uppercarriage with the mast is rotatably mounted.
  • the undercarriage can in particular have a crawler track.
  • the drives and a control station are preferably provided on the superstructure.
  • this is characterized in that the impact unit is connected to the base slide via a connecting rope at a distance that changes during a ramming process, the connecting rope being held in a tensioned state during a ramming process by means of a tensioning device.
  • the method can in particular be carried out with the previously described pile driving device.
  • the advantages described above can be achieved with the method.
  • a preferred embodiment of the method according to the invention consists in that a method of the basic slide is controlled as a function of the ramming process. This enables particularly efficient ramming of the material to be driven into the ground.
  • a distance between the basic slide and impact unit is detected and that when an upper limit value is exceeded, the basic slide is adjusted and the distance is thus reduced to a setpoint value.
  • the basic slide is reduced to a smaller target distance value by moving the basic slide accordingly.
  • the basic slide is automatically adjusted without interrupting the ramming process.
  • the control unit can interrupt the pile-driving process or output a warning signal due to a sudden stretching of the connecting rope.
  • a distance between the basic slide and the striking unit can be increased to a predetermined, larger setpoint distance if the value falls below a lower limit value, in order to avoid undesired direct contact between the basic slide and the striking unit.
  • FIG Fig. 1 A ramming device 10 according to the invention is exemplified in FIG Fig. 1 shown, wherein the piling device 10 has a carrier device 12 with an undercarriage 14, which is designed as a crawler track, and an uppercarriage 16 rotatably mounted thereon with an operating station 18.
  • a mast 23 in the form of a telescopic leader with a rigid leader element 20 is attached essentially vertically to the superstructure 16 via an adjustment mechanism 19, which is known in principle.
  • the adjustment mechanism 19 allows both pivoting movements of the mast 23 from the vertical as well as movement movements of the mast 23 in the longitudinal direction of the superstructure and in a vertical direction.
  • a movable leader element 21 is provided as a further component, which is movably and adjustably guided along the rigid leader element 20.
  • a linear guide 22 is formed, along which a base slide 30, also called a leader slide, is movably mounted.
  • the basic slide 30 is via a rope, not shown, which is guided via a roller attached to the movable broker element 21, also not shown, connected to the rigid broker element 20. If the movable leader element 21 is raised by means of a telescopic cylinder (not shown), the base slide 30 also moves upwards.
  • a block-like striking unit 40 is guided displaceably along the guide 22 of the leader element 21. Via a frame-like adapter device 42 on the upper region of the striking unit 40, this can be connected to the basic slide 30 via a connecting cable 36. Between the percussion unit 40 and the basic slide 30, only a connecting cable 36 is provided as a transmission element for vertical forces, which is advantageous when ramming in the pile 5 by means of the percussion unit 40.
  • a pile-shaped element with a rectangular cross-section is provided as the pile-up 5, which is received and held in a receptacle (not shown in detail) at the lower end of the striking unit 40.
  • Fig. 2 In the detailed view of Fig. 2 is the connection between the basic slide 30 and the impact unit 40 of the ramming device 10 of Fig. 1 Shown in more detail in the state in which the percussion unit 40 is moved upwards along the guide 22 of the leader element 21 with the base slide 30 via a lifting cable (not shown) by moving the adjustable leader element 21.
  • the striking unit 40 with the base slide 30 can be achieved by lowering the adjustable Gurklerlementes 21 are driven down. In this state there is still a distance A between the basic slide 30 and the percussion unit 40. This distance A is smaller than the length of the connecting rope 36 and the rocker 52.
  • the connecting rope 36 is held in a tensioned state via the tensioning device 50.
  • the tension springs 54 pull the pivotably mounted rocker 52 laterally upwards, so that the connecting cable 36 is tensioned, as if off Fig. 3 emerges.
  • an impact pulse can now be exerted on the pile 5 by an impact piston within the impact unit 40. It is important that the percussion unit 40 can follow the pile 5 when the pile 5 penetrates the ground, while the percussion unit 40 is still reliably connected to the base slide 30 without vibrations being transmitted.
  • FIGS Figures 4 and 5 show the displacement of the impact unit 40 with the pile 5 during a piling process corresponding to the penetration of the pile 5 into the ground.
  • a distance between the basic slide 30 and the striking unit 40 increases during this actual ramming process, the increasing distance being compensated for by changing the angular position of the rocker 52 of the clamping device 50.
  • the tension spring 54 which is arranged between the upper end of the rocker arm 52 and the base slide 30, ensures that the connecting rope 36 is sufficiently tensioned so that slack rope is avoided.
  • a sensor 60 is located on the base slide 30 for detecting an angular position of the rocker arm 52, a proximity sensor 62a and a distance sensor 62b, which are designed to determine a distance between the basic slide 30 and the striking unit 40.
  • the measured values recorded in each case are forwarded to a control unit which controls the tracking of the base slide 30 to the impact unit 40. This can be done by appropriate control pulses to the control of the telescopic cylinder, which moves the adjustable leader element.
  • the control unit as a whole is also designed to indirectly determine the distance between the base slide 30 and impact unit 40 on the basis of the angle measurement with respect to the rocker 52 and taking into account the geometric relationships. In this way, overstretching of the connecting rope 36 can be avoided. This protects the connecting rope 36 and prevents excessive vibrations from being transmitted to the base slide 30.
  • FIG Fig. 6 Such tracking of the basic slide 30 to the striking unit 40 is shown in FIG Fig. 6 made clear.
  • a distance can be reduced to a nominal distance A1 from the impact unit 40.
  • a further impact pulse can then be carried out by the impact unit 40.
  • the basic slide 30 with the attached striking unit 40 can then according to the state of Fig. 2 be pulled up again to pick up a new pile 5.
