摘要:
The invention relates to a side wall segment for a cable guide device (2) comprising links (3) pivotally connected to each other, each link having two opposite side parts (4) connected pivotally in a pivot plane to the immediately adjacent side parts and having stops (10) for limiting the pivot angle, wherein a plurality of side parts connected to each other form the side wall segment (1). The invention proposes that the side parts of the side wall segments be connected to each other integrally by a connecting web (5) extending in the longitudinal direction thereof and flexible in the pivot plane and have a web (6, 7) extending substantially perpendicular to said connecting web in the pivot plane and having a T-shaped longitudinal section and comprising a foot web (8) and a transverse web (9), wherein the foot web is connected to the connecting web and the transverse web is located at the end of the foot web opposite the connecting web, the faces of the transverse webs facing in the longitudinal direction of the web forming the stops for limiting the pivot angle.
摘要:
The invention relates to an active line guide (1), such as an energy guide chain for example, with wear identification. An apparatus (10) for identifying wear (detection of deterioration) in a critical region of at least one section (14) of the line guide is realized as a radio circuit and is distinguished by a transponder (20, 20A, 20B; 1220; 1320…) and at least one detector element (26; 1226, 1227; 1626) which interacts with the transponder and is arranged such that the detector element (26; 1226, 1227; 1626) changes the behaviour of the transponder when there is a predetermined extent of wear in the critical region (11). As a result, a wear-related change, for example by erosion, crack formation and/or fatigue fracture, can be identified in a wire-free manner, that is to say in a contact-free manner. A corresponding system and method and also an identification module (100; 190; 200) for fitting or retrofitting an active line guide (1) with a function for wear detection are proposed. A radio circuit (1610; 1710; 1810) for particularly reliable wear identification is also disclosed.
