Embodiment Construction

[0030] like figure 1 As shown, the trench wall cutter 1 may comprise an elongated and vertically arranged cutting frame 2, which may be designed as a lattice truss And / or may comprise two laterally arranged longitudinal guide profiles. At the lower end section, the cutting frame 2 can comprise at least two cutting wheels 3 which are arranged side by side and can be driven in rotation about a respective horizontal axis of rotation, wherein the axes of rotation of the cutting wheels 3 can be parallel to one another. extends, in particular perpendicular to the flat sides of the cutting frame 2 .

[0031] Here, the two cutting wheels 3 can be driven in opposite directions to each other. The cutting drive 4 can be arranged above the cutting wheel 3 at the lower end section of the cutting frame 2 and comprises, for example, one or more hydraulic motors which can drive the cutting wheel 3 via one or more gear stages.

[0032] like figure 1 As shown, the carrier device 5 can hold...

Abstract

The present invention relates in general to slurry wall cutters for cutting slurry walls in specialist foundation engineering. The invention relates in particular to the cutting wheel assembly for such a slurry wall cutter (1), comprising a rotationally drivable cutter hub (8) and a cutting wheel (3) which can be detachably fastened to the cutter hub for conjoint rotation. According to the invention, the cutting wheel and the cutter hub are clamped against one another at the end faces thereof and are interlockingly secured to one another in order to transmit the high operating forces non-frictionally or at least not only frictionally. According to the invention, the end faces of the cutting wheel and the cutter hub that can be placed against one another are provided with lateral teeth (16, 17) which mesh with one another for conjoint rotation. The meshing pair of lateral teeth allows the cutter hub and the cutting wheel to be interlockingly held relative to one another for conjoint rotation. At the same time, the end faces lying against one another can also transmit axial forces such that the cutting wheel is untiltably held in place.

Description

technical field [0001] The present invention generally relates to trench wall cutting machines for cutting trench walls in special civil engineering Herein, the invention relates in particular to a cutting wheel arrangement for such a trench wall cutting machine The cutter wheel arrangement includes a rotatably driven cutter hub and a cutter wheel removably secured to the cutter hub in a non-rotatable manner. Background technique [0002] Trench wall cutters are often used in special civil engineering to cut trenches in soil, rock or foundations which are filled with a suspension containing eg concrete to form the trench walls. A trench wall is generally a wall structure in a foundation eg made of concrete, reinforced concrete or the like. To manufacture such trench walls, substantially vertical, upwardly opening trenches are cut using a trench wall cutter, wherein the cutting tool is lowered into the ground from above and is supported by a, preferably movable Carrying ...
