Definitions

  • the invention relates to a diesel ram, comprising a cylinder, a piston displaceably guided in the cylinder and a striking piece displaceably guided in the cylinder according to the preamble of patent claim 1.
  • Diesel rams also referred to as diesel hammers or diesel bears, are used in particular for foundation work of the construction industry for driving in piles of all kinds, such as concrete pillars, iron girders, sheet pile wall elements or the like in a building ground.
  • the piston is pulled upwards by means of a notching device inside the cylinder and disengaged at a certain height, whereby it falls down on the striking piece under the action of gravity.
  • 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, with the expanding combustion gases flowing out of the working nozzles and subsequently sucking fresh air into the combustion chamber through the piston rising further upwards.
  • the pile is driven over the hammer in the ground.
  • Diesel rams of the aforementioned type as described for example in the EP 1 828 488 B1 has been described, have proven in practice because of their simple structure and the resulting reliability. In operation, however, such diesel rams are very noisy and can cause a noise level of 100 decibels (A) and more.
  • A decibels
  • US 3,897,851 It is proposed to provide the working nozzle with an exhaust air muffler.
  • a diesel ram of the aforementioned type is provided, the noise emission is reduced.
  • the at least one nozzle is provided with a muffler device, initiated by the expansion of the combustion gases noise emissions are significantly reduced.
  • the at least two working nozzles are arranged on two horizontally spaced conceptual horizontal planes, so that at least one working nozzle is arranged vertically offset relative to a second working nozzle, wherein the at least one arranged on the lower levels lower working nozzle is provided with a muffler device. If the piston is thrown upwards, it first releases the lower working neck, after which the exhaust gases escape through the silencer. Subsequently, the vertically offset second work socket is released, whereby fresh air can be sucked into the combustion chamber.
  • the at least one arranged on the upper level upper working neck on a muffler device Preferably, the at least one arranged on the upper level upper working neck on a muffler device.
  • a muffler device Preferably, an unhindered influx of fresh air is achieved in the combustion chamber. An entry of in an arranged muffler possibly adhering dirt particles in the combustion chamber is thus avoided.
  • the two planes between 80 mm and 120 mm, preferably between 95 mm and 115 mm spaced apart. It has been found that this achieves an optimum trajectory of the upwardly moving piston, in which the combustion gases escape from the lower working nozzle provided with a silencer device, before the upper working nozzles are released, whereby fresh air is drawn into the combustion chamber.
  • the muffler device is formed by a sheathed perforated tube.
  • a simple and effective absorber-muffler is formed, which is not susceptible to contamination by combustion gases.
  • the muffler device is mounted elastically supported by means of vibration elements on the cylinder.
  • the vibration elements are formed as elastomer or rubber components.
  • a striking hood for receiving the ramming material is arranged below the striking piece, wherein the hammering piece is at least partially surrounding a sound absorbing element arranged. As a result, a damping of the impact of the hammer on the striking hood resulting noise emissions is effected.
  • the sound absorption element is formed from at least one filled with an absorber material perforated sheet cassette.
  • the absorber material is preferably formed from mineral insulation wool, hard melanin foam or other suitable porous material.
  • the diesel ram selected as an exemplary embodiment comprises a cylinder 1 which is open on both sides and which can regularly have a length of 3 to 8 meters and a diameter of 0.2 to 1.5 meters.
  • a piston 2 is slidably disposed in the cylinder 1 a.
  • a coaxial to this impact piece 3 engages slidably in the open lower end of the cylinder 1 a.
  • an annular bearing unit 9 is fixed, in which a middle shaft portion 31 of the hammering piece 3 is guided tightly and displaceably, which has a relation to the inner diameter of the cylinder 1 reduced outer diameter.
  • the diesel ram is mounted vertically displaceable over arranged on the cylinder 1 guide jaws 13 along a leader 8.
  • a striking plate 32 located below the cylinder 1, the outwardly directed lower convex boundary surface 33 cooperating in operation with the upper end of a driven-in pile material to be driven in.
  • a piston portion 34 is formed with a plurality of circumferential, axially spaced sealing rings which run on the inner circumferential surface 11 of the cylinder 1.
  • a combustion chamber 12 is limited together with the underside of the piston 2 and the inner circumferential surface 11 of the cylinder 1.
  • the combustion chamber 12 of the cylinder 1 facing end face of the hammer 3 is ground flat with a shallow fuel well.
  • a damping ring 91 is arranged between the impact plate 32 of the hammer 3 and the bearing unit 9 of the cylinder 1.
  • a further damping ring 92 is arranged adjacent to the bearing unit 9 between the upper side of the bearing unit 9 and the underside of the piston portion 34 of the hammer 3.
  • hammer 3 runs in the interior of the cylinder 1 with a circumferential, axially spaced-apart sealing rings 93 provided, lower working end 23 of the piston 2.
  • the lower free, ground flat end face 21 of the piston 2 is offset by a radially outwardly encircling step.
  • a mass portion 2 is formed, which extends in the upper portion of the cylinder 1 inside.
  • an injection device 4 is arranged, which comprises a fuel pump 41 which is connected via a line 43 to the injection nozzle 42.
  • the inlet of the fuel pump 41 is supplied with diesel oil via a fuel tank 45.
  • the fuel pump 41 has a prestressed pump lever 44 projecting into the interior of the cylinder 1, by means of which it is driven when the falling piston 2 passes.
  • the injection nozzle 42 is designed and aligned such that the discharged fuel is injected in a substantially continuous jet approximately centrally on the end face of the hammer 3.
  • a lubricant pump 7 is arranged on the cylinder 1, which is connected to distributed in the circumferential direction of the cylinder 1 lubricant nozzles. Through the lubricant nozzles lubricant between the piston 2 and the inner circumferential surface 11 of the cylinder 1 is given.
  • the peripheral wall of the cylinder 1 is penetrated by two obliquely upwardly extending working nozzle 16, 17, sucked on the combustion air or combustion gases are discharged.
  • the muffler device 5 is essentially formed by a perforated tube 51 provided with a lug pipe section 52, which is arranged centrally in a cylindrical casing 53.
  • the sheath 53 is provided on both sides with a respective receiving flange 54, which receives the perforated tube 51 and which is provided radially circumferentially with holes 55.
  • the muffler device 5 is attached to the cylinder 1 by means of two holding arms 56 arranged at a distance from each other, wherein 5 vibration elements 57 are arranged between the holding arms 56 and the casing 53 of the muffler device, whereby a substantial decoupling of the muffler device 5 from the cylinder 1 is effected.
  • the approach pipe section 52 of the muffler device 5 opens into the lower working socket 16 of the cylinder 1.
  • the lower working socket 16 is arranged offset by 105 millimeters from the upper working socket 17 vertically.
  • the mass portion 22 of the piston 2 a - not illustrated - a driving shoulder forming undercut for engagement of a driver of a - not shown - release device.
  • a striking hood 6 for receiving a pile 81 is arranged below the hammer 3 of the diesel rams.
  • the striking hood 6 is essentially formed by a receptacle 61 encompassing the pile 81, which has a striking plate 62 on its side facing the hammer 3.
  • the receptacle 61 is surrounded by a hood part 63, which projects beyond the receptacle 61 in the direction of the striking piece 3.
  • a frame is formed above the receptacle 61, to which the striking piece surrounding sound absorbing elements 64 are arranged, which rest on the receptacle 61.
  • the sound absorbing elements 64 are designed such that a collision of the hammer 3 with the sound absorbing elements 64 is avoided, however, as the impact plate 32 of the hammer 3 is completely surrounded, creating a significant attenuation of the beating of the hammer 3 on the striking plate 62 of the striking hood 6 generated noise emissions is effected.
