Problems solved by technology

Even though this type of embodiment is advantageous for a short overall axial length, its main disadvantage is that the drive unit must be configured to generate a high torque so that when a certain or considerable length of the flat belt has been wound and thus has reached a substantial effective diameter, it is still possible to rotate the winding drum against the tension of the load

Embodiment Construction

[0020] figure 1 A perspective view of a complete drive unit for a scenery lifter in a stage machine is shown with a winding drum 2 driven rotatably about an axis of rotation 4 . The winding drum 2 has six winding areas 6 arranged next to each other for individual pulling means (in this embodiment, pulling ropes 8 ), which are configured in the form of receiving spaces with a base diameter d, which are groove-shaped or shaped like a cylindrical ring and extend radially to the axis of rotation 4 and are in each case separated from each other by a narrow partition 10 arranged between them. The clear width B of each take-up area 6 corresponds to the diameter D of the traction rope (or the width of the traction belt) received therein or slightly larger, so that the traction means involved can be wound up to the coil-up area without difficulty 6 in. For this purpose, the end of each pulling means 8 on the side of the winding drum is fixed to said winding drum 2 at the base of its ...

Abstract

Drive unit for at least one traction device (8), in particular in a stage machine, having a winding drum (2) with at least one receiving area (6) on which (in each case) is accommodated A pulling device, which can be wound up or uncoiled, is characterized in that a cylindrical driving area (14) is arranged on the winding drum axially adjacent to said receiving area, and can be wound up or An unwound belt-like drive means (12) is accommodated on said cylindrical drive area, and said belt-like drive means may be wound on a drivable drive roller (18) in order to act on Drive torque on the winding drum, or unwinding from the driving drum to release the winding drum.

Description

technical field [0001] The invention relates to a drive unit for at least one traction means, such as a traction cable or belt, especially in stage machinery, which has a winding drum comprising at least one take-up area, which can be wound up or unwound Pulling means are received on (each of) the take-up areas. Background technique [0002] DE 10 2005 049 105 A1 discloses a drive unit for a lifting system of a stage machine, in which flat belts are used as traction means for lifting and lowering loads. Even though this type of embodiment is advantageous for a short overall axial length, its main disadvantage is that the drive unit must be configured to generate a high torque so that when a certain or considerable length of the flat belt has been wound and thus having reached a substantial effective diameter, it is still possible to rotate the winding drum against the tension of the load. Contents of the invention [0003] The technical problem of the present invention i...
