Embodiment Construction

[0020] The diesel pile driver of the chosen embodiment comprises a cylinder 1 open on both sides, which may typically have a length of 3 to 8 meters and a diameter of 0.2 to 1.5 meters. A piston 2 is movably arranged in the cylinder 1 . A striker 3 coaxial therewith is movably engaged in the open lower end of the cylinder 1 . At the lower end of the cylinder 1 is fixed an annular bearing unit 9 in which a central rod section (Schaftabschnitt) 31 (which has an inner diameter relative to the cylinder 1 ) of the striker 3 is guided tightly and displaceably. reduced outer diameter). The diesel pile driver is mounted vertically displaceable along an intermediate piece 8 via guide carriages 13 arranged on the cylinder block 1 .

[0021] At the lower end of the rod section 31 is molded an impact plate (Schlagplatte) 32 located below the cylinder 1 , whose downwardly protruding lower limiting surface 33 cooperates with the upper end of the pile driving object to be pressed in during...

Abstract

A diesel hammer pile driver has a cylinder, a piston displaceably guided in the cylinder and a striker displaceably guided in the cylinder. The striker is disposed underneath the piston in the operating position of the diesel hammer pile driver. A combustion chamber is delimited axially by a face surface of the striker that lies in the interior of the cylinder and by a face surface of the piston, and opens into a fuel feed device. Using the fuel feed device a predetermined amount of fuel can be introduced into the combustion chamber during each working cycle. At least two working connectors are disposed to pass through the circumference wall of the cylinder at the level of the fuel feed device, wherein at least one working connector is provided with a muffler device.

Description

technical field [0001] The invention relates to a diesel pile driver according to the preamble of claim 1 with a cylinder, a piston displaceably guided in the cylinder and a striker (Schlagstück) displaceably guided in the cylinder ( Dieselramme). Background technique [0002] Diesel pile drivers (also known as Diesel hammers (Dieselhammer) or diesel hammers (Dieselbör)) are used especially in foundation work in the construction industry for ramming (Einrammen) all types of piles (e.g. cement columns, Iron frames, sheet pile wall elements (Spundwandelement, etc.). [0003] To start such a diesel pile driver, the piston is pulled upwards by means of a release device in the cylinder and released at a certain height, whereby the piston falls under the force of gravity onto the striker . During the descent, the fuel pump is actuated by means of the piston, and the delivery of fuel, in particular diesel, takes place via the fuel pump. The air located in the combustion chamber...
