DE2028282B - Rotating device working alternately in opposite directions to facilitate driving in or pulling out jacking pipes, piles, oddgl - Google Patents

Description

vei sets over the bearing ring 7 in rotation, wherein after a rotation of about 50 ° JEach rocker 2 with the stops arranged on its inner flange on the corresponding counterstops of the bearing ring? and the flywheel energy is transmitted via the bearing ring 7 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 one end position the one outer edge 2 'of the rocker 2 lies parallel to a boundary wall 19, while after reaching the opposite end position the other outer edge 2 ' is also parallel to the boundary wall 19, as the dash-dotted line shows Way, it is possible, the propulsion pipe 1 with the rocker 2 closely adjacent to the boundary wall 19 to be arranged, since the two end positions of the rocker 2 in a parallel to the boundary wall 19 directed straight lines. In order to ensure the exact compliance with these end positions and to prevent that the flyweights 3 can strike the boundary wall 19, limit switches, not shown, are arranged on the rotating device.

Counter elements which can be brought into engagement. This object is achieved according to the invention. treatment elements releasably on the propulsion pipe releases that the two arms of the rocker to their the or the like. can be put on, thereby marked swingweights bearing ends, in the shows that the two arms of the swing arm, viewed from above, steadily tapering off into a point, (2) to their swing weights (3) supporting 35 that each swing weight with an outer surface Ends towards, seen in plan view, steadily in alignment with the outer edge of the associated arm a point that each swing weight runs on the swing arm, and that an adjustable (3) is provided with an outer surface in alignment with the control device for the feeding of the pressure with outer edge (2 ') of the associated arm of the device to the drive cylinders.
Rocker (2) runs and that an adjustable 30. As a result of the design according to the invention, reversing device for the supply is achieved so that the rotating device can work with very little pressure on the drive cylinders (8) at a distance from a boundary wall. since full utilization of the effective rotation 2. Rotating device according to claim 1, characterized by about 50 ° immediately next to the limit, that the swing weights (3) with 35 tongue wall is possible because the rocker with their their centers of gravity in the central axis of the swing weights in both end positions parallel Rocker arm (2). to the boundary wall. The reversing device 3. Rotating device according to claim 1 or 2, device of the drive cylinder is adjustable so that the characterized in that on the turning device does not have the parallel position of the direction causing a reversal, can be moved with a local rocker to the boundary wall Fixed stops interacting Endschal- can. ter are arranged. It is useful that the swing weights; with ih ren centers of gravity lie in the center axis of the rocker arm. This avoids harmful unilateral 45 stungen the swing arm avoided and thus signs of wear largely prevented on the rotating device and on the propulsion pipe. In order to be certain of damage to the The invention relates to an alternating tongue wall by avoiding the turning device working in opposite directions close to its standing turning device, it is advantageous to reverse the direction in the direction to facilitate the driving in or out of the turning device, with pulling out of the propulsion pipes, Poles or the like, end shells that interact with stationary stops are to be arranged on bearings attached to the propulsion pipe or the like. The reversal takes place when the wreath and one on it around the propulsion pipe or the like. The stationary stops can be arranged here to the pipe axis and provided at their ends with a swing weight, for example, each arranged on the boundary wall; When the end position of the rocker is reached, it comes into contact with several stops on the bearing ring or on one inside with the limit switches arranged on the rocker arm, the limit switches being actuated and with drive cylinders, their housings and 60 and cause the necessary reversal.
