PROTECTION OF FIBRE-OPTIC CABLE IN MINING EQUIPMENT Russian patent published in 2016 - IPC E21C35/04 E21C35/24 

FIELD: machine building; mining.

SUBSTANCE: invention relates to development of a long face and more specifically to chain cable layer in equipment for development of long face, specifically to a device with chain links, a cable chain assembly and mining apparatus. Device with chain links for a cable chain assembly comprises a chain link having walls cooperating to define a compartment opening in direction of axis, fibre optic cable being configured to be supported in said compartment, communications configured to be supported in said compartment; and a flexible member supported in said compartment and configured to engage with fibre optic cable, flexible member positioning fibre optic cable toward one of said walls. Cable chain assembly for mining machine comprises chain links, each of which has upper wall, lower wall, first side wall and second side wall together defining a compartment, open in direction of said axis. Fibre-optic cable passing through compartment in each of chain links and passing substantially in wavy path. First flexible member supported in compartment of one of chain links configured to interact with fibre-optic cable and positioning a fibre-optic cable in upper wall of said one of chain links. Second flexible member supported in compartment of second chain link, configured to interact with fibre-optic cable and positioning a fibre-optic cable in lower wall of second chain link.

EFFECT: prevention of excessive tension and cable damage due to provision of sufficient specified cable sag.
