Definitions

  • the invention relates to a piling device comprising a diesel ram with a cylinder, a piston displaceably guided in the cylinder, and a striking piece displaceably guided in the cylinder and a release device according to the preamble of patent claim 1.
  • Piling devices with diesel rams which are also referred to as diesel hammers or diesel bears, are used in particular for foundation work of the construction industry for driving piles of all kinds, such as concrete pillars, iron girders, sheet piling or the like into a ground.
  • the piston is pulled by means of a notching device inside the cylinder up and disengaged at a certain height, whereby it falls under the action of gravity down on the hammer.
  • a fuel pump is actuated by the piston, via which a supply of fuel, in particular of diesel oil takes place.
  • the air in the combustion chamber of the cylinder is compressed and thereby heated so that ignited in the combustion chamber fuel / air mixture, whereupon it burns explosively.
  • the piston is hurled upward again for a new working cycle; at the same time the pile is driven over the hammer in the ground.
  • the notching device for lifting the piston within the cylinder has a driver which engages in an undercut of the piston. After reaching the lifting height required for the start of the driver is moved out of the cylinder chamber via a Ausklinknocken, whereby the piston is released.
  • the notching device is regular, as well as the cylinder led to a leader.
  • traceable Gurkrom can it happen here that is moved by an inaccurate tracking of the leader and / or the notching device located on this release device in the direction of Einklinknockens, whereby the driver is unintentionally pivoted into the cylinder. This can cause damage to the piston as well as the release device.
  • a corresponding problem arises, for example, in embodiments in which the driver is arranged on an auxiliary structure directly to the diesel rams. In addition, an unwanted pivoting can also be caused by incorrect operation.
  • the invention aims to remedy this situation.
  • the invention is based on the object to provide a diesel ram of the aforementioned type, in which an unintentional pivoting of the driver of the notching device is avoided in the cylinder chamber. According to the invention, this object is solved by the features of the characterizing part of patent claim 1.
  • a diesel ram of the aforementioned type in which an unintentional pivoting of the driver of the notching device is avoided in the cylinder chamber.
  • collision area is to be understood here as the area which the operating lever covers over the possible displacement path of the release device. If the Einklinknocken or the operating lever moved out of the collision area, an impact of the operating lever on the Einklinknocken is no longer possible.
  • diesel rammer is to be understood below as any fuel-powered slate.
  • the latching cam and / or the operating lever is designed as a cylinder, preferably as a hydraulic cylinder.
  • a remote-controlled moving out of the Einklinknockens or the operating lever is made possible from the collision area.
  • the Einklinknocken and / or the operating lever can also be formed out of the collision area swiveling or rotatable.
  • the driver in the notching device is designed such that it is locked after swinging in and after swinging out by the operating lever in the respective pivot position. As a result, an unwanted pivoting of the driver is further counteracted.
  • the fuel supply device comprises a pump lever which protrudes into the cylinder so that it is actuated when passing the piston, whereby fuel is introduced to the end face of the hammer, with a Ausklinknocken is provided, which is positionable such that in collision of the operating lever with this Ausklinknocken the piston has not yet passed the pump lever so that no fuel enters the combustion chamber.
  • a "soft", controlled pre-ramming of a pile is made possible, whereby an unintentional drifting of the pile is avoided in soft substrates.
  • the piston can be lifted to the required height for the start and then released, whereby the pump lever is actuated by the piston and thereby fuel is injected into the combustion chamber.
  • the Ausklinknocken is axially slidably disposed on the cylinder and lockable in at least two positions, wherein the determination of the Ausklinknockens in a first position causes a disengagement of the piston in a position after passing the pump lever, the determination of the Ausklinknockens in a second Position a notching of the piston in a position before passing the pump lever causes.
  • the two notching positions "gentle pre-ram" and "start” are made possible by a single, displaceable Ausklinknocken.
  • two Ausklinknocken axially spaced from each other on the cylinder are arranged, wherein the upper, first Ausklinknocken is arranged such that when it collides with the operating lever of the release device, a disengagement of the piston is effected in a position after passing the pump lever and the second lower Ausklinknocken is arranged such that in collision with the operating lever of the notching device, a disengagement of the piston is effected in a position before passing the pump lever, wherein the lower Ausklinknocken is formed such that it can be moved out of the collision region of the operating lever of the notching device.
  • the two modes of "soft pramming" and “starting" without displacement of a Ausklinknockens possible.
  • the second Ausklinknocken is designed as a cylinder, preferably as a hydraulic cylinder.
  • the cylinder and the release device are slidably mounted on a leader, wherein at least one orthogonal to the pivoting direction of the driver retractable pawl is disposed on the release device, which is positionable under an outside of the cylinder arranged Mitauersteg and on which of the cylinder along of the Gurklers is movable.
  • two pawls are arranged, which are eccentrically connected in such a way with a circular disk, that by rotation of the circular disk, a retraction or extension of the pawls in opposite directions is possible.
  • This allows a simple and reliable positioning of the pawls on the drivers of the cylinder.
  • the opposite arrangement of the pawls counteracts tilting of the cylinder when pulling along the Gurklers.
  • the piling device chosen as an exemplary embodiment comprises a diesel ram with a cylinder 2 which is open on both sides and which can regularly have a length of 5 to 10 meters and a diameter of 0.2 to 1 meter.
  • a piston 3 is slidably disposed in the cylinder 2 a.
  • a coaxial to this impact piece 4 engages slidably in the open lower end of the cylinder 2 a.
  • an annular bearing unit 9 is fixed, in which a central shaft portion 41 of the hammer 4 guided tightly and slidably is having a reduced diameter compared to the inner diameter of the cylinder 2 outer diameter.
  • a striking plate 42 is formed below the cylinder 2 formed, the outwardly directed lower convex boundary surface 43 cooperates in operation with the upper end of a driven-in pile material.
  • a piston portion 44 is formed with a plurality of circumferential, axially spaced sealing rings 91 which run on the inner circumferential surface 21 of the cylinder 2.
  • a combustion space 22 is limited together with the underside of the piston 3 and the inner circumferential surface 21 of the cylinder 2.
  • the combustion chamber 22 of the cylinder 2 facing end face 45 of the hammer 4 is ground flat with a flat fuel trough 46.
  • damping ring 92 is arranged between the striking plate 42 of the hammer 4 and the bearing unit 9 of the cylinder 2.
  • Another damping ring 23 is arranged adjacent to the bearing unit 9 between the top of the bearing unit 9 and the underside of the piston portion 44 of the hammer 4.
  • a mass portion 32 is formed, which extends into the upper portion of the cylinder 2 inside.
  • an injection device 5 On the peripheral wall of the cylinder 2, an injection device 5 is arranged, which comprises a fuel pump 51, which via a line 53 to the injection nozzle 52 is connected. The inlet of the fuel pump 51 is fed via a fuel tank 54 with diesel oil.
  • the fuel pump 51 has a prestressed pump lever 55 projecting into the interior of the cylinder 2, via which it is driven when passing the falling piston 3.
  • the injection nozzle 52 is designed and aligned such that the discharged fuel is injected in a substantially continuous beam approximately centrally on the end face 45 of the striking piece 4.
  • the peripheral wall of the cylinder 2 is penetrated by obliquely upwardly extending working nozzle 23, sucked on the combustion air or combustion gases are discharged.
  • the mass portion 33 of the piston 3 has an engaging shoulder forming an undercut 34 for engagement of a driver 73 of a notching device 7.
  • two carrier webs 28 for engaging the pawls 76 of the release device 7 are furthermore arranged on the cylinder 2.
  • the release device 7 comprises a housing 70, on which a guide 72 is arranged for slidable mounting to a broker 8.
  • a driver 73 is pivotally mounted in the housing 70.
  • the driver 73 is connected to an operating lever 74, via which it is pivotable.
  • a pulley 75 is arranged at its the control lever 74 opposite, upper end of the housing 70.
  • the notching device 7 along the Switzerland Switzerland is movable.
  • the Einklinknocken 26 is positioned on the cylinder 2, that upon actuation of the operating lever 74 when abutting the Einklinknocken 26 of the driver 73 is pivoted below the undercut 33 of the piston 3 by an introduced into the cylinder 2 slot 27 in the interior of the cylinder 2.
  • the operating lever 74 is provided on its side facing the Einklinknocken 26 side end with a radius, which he better along the Einklinknockens 26 slides along.
  • a recess 71 is formed in the housing 70 of the notching device 7, through which a stop 711 is formed for the Einklinknocken 26.
  • a pivoting of the operating lever 74 is thus possible only until reaching the stop 711 by the Einklinknocken 26.
  • the release device 7 can be moved over the cable 81 along the leader 8, whereby the driver 73 engages in the undercut 33 of the piston 3 and the piston 3 is moved within the cylinder 2 upwards. If the operating lever 74 abuts on the upper Ausklinknocken 24, the driver 73 is pivoted out, whereby the piston 3 is released and due to gravity falls in the direction of the hammer 4.
  • the piston 3 passes through the pump lever 55 of the injector 5, which is sprayed via the injector 52 fuel to the fuel bowl 46 of the hammer 4, which explodes upon impact of the piston 3 on the hammer 4, whereby the piston 3 is catapulted back up.

  • the piston 3 beats so once on the hammer 4, whereby the pile to be recovered experiences only one stroke. By repeating this procedure, a "soft", controlled driving the pile is possible in particular in a soft ground.
  • the piston 3 After retracting the lower Ausklinknockens 25, the piston 3 can then be driven on the release device 7 further up until the operating lever 74 abuts the upper Ausklinknocken 24, the piston 3, the pump lever 55 has completely passed, which is why this due to its bias in the cylinder space 2 protrudes.
  • the pump lever 55 is actuated, as a result of which fuel injection takes place on the fuel trough 46 of the striking piece 4.
  • the Dieselramme 1 is started.

  • the circular disk 77 which may also be designed as a cylindrical element, is connected to a control lever 78, via which it is rotatable.
  • the adjusting lever 78 can be operated via a cord attached to this.
  • the circular disk 77 is held with a - not dargestellen - spring element in a position in which the pawls 76 are extended. The retraction of the pawls 76 takes place by pulling on the cord 79.
  • the piling device 1 described above operates as follows: In the initial state, the release device 7 is moved such that the housing 70 rests with its housing 70 on the latching cam 26 of the cylinder 2 of the diesel ram 1, whereby the operating lever 74 is moved upward, whereby the driver 73 is pivoted through the slot 27 in the cylinder 2. Subsequently, the release device 7 is moved over the rope 81 upwards, whereby the driver 73 engages in the undercut 33 of the piston and the piston 3 is pulled up. When the operating lever 74 stops at the upper release cam 24, the driver 73 is retracted, whereby the piston 3 is released.
  • the diesel hammer may optionally be "manual" for pre-positioning a pile in a soft soil or in an "automatic” mode with self-indicating work cycles by auto-ignition of injected fuel.
