Embodiment Construction

[0046] Figures 1A-1B A monitoring system is shown as a schematic diagram, the entire monitoring system being designated 10 , which is used to monitor the functioning of an energy guide chain 12 (hereinafter abbreviated as: EFK12 ). The monitoring system 10 comprises as main components: a specially adapted (or equipped) energy guide chain 12 ; an analysis and processing unit 14 ; and a detector 16 arranged on the energy guide chain 12 . The detector 16 is signal-technically connected to the evaluation unit 14 . The monitoring system 10 serves in particular to prevent breakage of the guided pipeline in the event of a failure of the energy guide chain 12 .

[0047] When the energy guide chain 12 is partially or completely disconnected at a certain position (for example at Figure 1B As shown at 13 in ), the energy guide chain generally no longer fulfills its function. After a break, the energy guide chain 12 does not guarantee the protection of the pipeline, which is not shown...

Abstract

The invention relates to a drag chain (12) having additional protection against line breaks. The drag chain comprises links (20) or segments for guiding one or more lines, such as cables, hoses, or the like, wherein the links or segments can be pivoted in relation to each other in order to form a deflecting curve (28). The protective equipment comprises a detector, which is provided for monitoring the drag chain. The detector (16) is mechanically operatively connected to a low-elongation triggering string (30) and has a sensor (36) for sensing a kinematic parameter of the triggering string (30). A break (13) in the drag chain (12) can be detected in good time by means of the change of the kinematic parameter. Thus, guided cables, hoses, or the like can be protected against line breaks.

Description

technical field [0001] The invention relates to an energy guiding chain comprising a plurality of interconnected links or segments for guiding one or more lines between a base and a driver movable relative to the base. The chain links or segments are bendable relative to one another in order to form the deflection arc. Various possibilities are known which can be used to construct energy guide chains. The energy guide chain can for example consist of individual chain links. An energy guide chain in this sense can also be produced in one piece or completely in one piece, in sections, from a plurality of bendable chain segments. The invention can thus be applied not only to real link chains, but also to line guides which are produced completely in one piece in the longitudinal direction. [0002] Energy-guiding chains, in particular energy-guiding chains that are not completely protected from external influences, can be damaged, for example by stuck foreign bodies. Here, a p...
