DE2028282C - Rotating device that works alternately in opposite directions to facilitate driving in or pulling out jacking pipes, piles, oddgl - Google Patents

Description

C / T

over the bearing rim? set in rotation, where after a rotation of about 50 °, the rocker arm 2 with the stops arranged on its inner flange on corresponding counterstops of the bearing ring 7 and the centrifugal energy on the Bearing ring 7 transfers to the propulsion pipe 1.

At the two ends of the rocker the swing weights 3 are arranged, both with their an outer surface flush with the outer edge 2 ′ of the rocker 2. Like the picture shows, in the one “end position, the one outer edge 2 'of the rocker arm 2 lies parallel to a boundary wall 19, while d after reaching the opposite end position the other outer edge 2 ' also lies parallel to the boundary wall 19, as the dash-dotted representation shows. To this Way, it is possible to use the earpiece I with the To arrange rocker 2 closely adjacent to the boundary wall 19, since the two end positions of the Rocker 2 lie in a straight line parallel to the boundary wall! To ensure exact compliance to ensure these end positions and to prevent the flyweights 3 from hitting the boundary wall 19, limit switches, not shown, are arranged on the rotating device
