Embodiment Construction

[0032] In the figures and in the following description, the same reference symbols are used in each case for identical or mutually corresponding features.

[0033] figure 1 An overview of a hose lifter 10 is shown with a lifting hose 12 described below, wherein the end of the lifting hose 12 is coupled via a handling device 14 to a suction gripping device 16 . The lifting hose 12 is connected with its end opposite the suction gripping device 16 to the support body 18 , in particular the suspension point 20 of the lifting hose 12 is displaceable in a transverse direction 22 .

[0034] Objects to be gripped (not shown) can be sucked by means of the vacuum gripping device 16 . By suitable actuation of the operating device 14 , the lifting hose 12 can be shortened by applying a negative pressure to its hose interior (see below) and thus the grasped object can be lifted.

Abstract

The invention relates to a lifting hose and a vacuum lifting device with such a lifting hose. The lifting hose has a hose wall extending around a longitudinal axis and enclosing a hose interior, wherein the lifting hose is reversibly deformable along the longitudinal axis into an elongated configuration and into a constricted configuration in the hose interior. The case is capable of deforming into a collapsed configuration. The hose wall has a plurality of outer bend lines along which the hose wall can be bent to produce the collapsed configuration, wherein the outer bend lines run obliquely to one another in such a way that when deformed into the collapsed configuration , the hose wall undergoes a twist about the longitudinal axis in sections.

Description

technical field [0001] The invention relates to a lifting hose and an operating device. Background technique [0002] Hoisting hoses of this type are used, for example, in hose hoists. In this case, the lifting of the gripped object is assisted by shortening the lifting hose caused by the negative pressure. However, other applications such as pneumatic actuators are also conceivable for lifting hoses. In this case, the elongation of the lifting hose by the negative pressure can exert a force on the object, for example in order to lift or move a load. [0003] Hose lifters with lifting hoses of this type are described, for example, in WO 2005 / 110907 A1 or US Pat. No. 4,413,853. The lifting hose has a bellows-shaped configuration with circumferential annular folds formed alternately as inner and outer folds along the axial extension, or with a longitudinal axis with a spiral shape surrounding the lifting hose The shape of the spiral fold line. Usually, a metal bracket is ...
