Embodiment Construction

[0022] The piling device chosen as an example comprises a diesel piling hammer with a cylinder 2 open on both sides, which can often have a length of 5 to 10 meters and a diameter of 0.2 to 1 meter. A piston 3 is displaceably arranged in the cylinder 2 . A hammer 4 coaxial therewith engages displaceably in the open lower end of the cylinder 2 . Fastened to the lower end of the cylinder 2 is an annular bearing unit 9 , in which the central rod section 41 of the striker 4 is guided sealingly and displaceably. The inner diameter of the cylinder 2 is reduced by the outer diameter.

[0023] On the lower end of the rod section 41 is formed an impact plate 42 below the cylinder 2 , whose outwardly directed lower convex boundary surface 43 is in contact with the piling object to be driven during operation. The upper end works together.

[0024] Formed on the upper end of the rod section 41 of the hammer 4 is a piston section 44 with a plurality of circumferential, axially spaced-ap...

Abstract

The invention relates to a piling device comprising a diesel pile hammer and a loosening device; the diesel pile hammer comprises a cylinder, a piston movably guided in the cylinder and an impact piece movably guided in the cylinder; the impact piece is arranged below the piston in an operation state of the diesel pile hammer; the loosening device comprises a moving part; the moving part can be moved to one side recessed portion of the piston through a gap of the cylinder; the cylinder is provided with a lower locking boss, and the loosening device is provided with an operation lever; the locking boss (26) and / or the operation lever (74) are formed in the following mode: the locking boss and / or the operation lever can be moved out from a crush zone of the operation lever (74) or a crush zone of the locking boss (26) of the loosening device (7).

Description

technical field [0001] The invention relates to a piling device according to the preamble of claim 1, comprising a diesel piling hammer with a cylinder, a piston guided movably in the cylinder, and a release device and an impact member movably guided in said cylinder. Background technique [0002] with also denoted diesel hammer or diesel hammer The piling unit of the Diesel Pile Hammer is used especially in foundation work in the construction industry to drive all types of piles, such as concrete columns, iron bearing parts, sheet piles (Spundwandelementen) or similar piles into the foundation. [0003] To activate such a diesel pile hammer, the piston is pulled upwards inside the cylinder by means of a release device and released at a certain height, whereby the piston falls under the force of gravity onto the striker superior. During the descent, the piston actuates a fuel pump via which fuel, in particular diesel, is delivered. The air in the combustion chamber of...
