Abstract
The invention relates to a multipart chain fixing device for securing at least one conveyor chain on a trough element of especially an underground scraper chain conveyor. The fixing device comprises a bridge part (), which has a bridge bar () that at least partially overlaps the conveyor chain in a positive-locking manner and ends in two lateral side end portions (). It also comprises two side parts (), which are fastenable to the trough element pan and to which the side end portionsare releasably securable by positive-locking means. For providing a chain fixing device, inclusive of the associated trough element and the individual components, which offer increased safety in underground usage, combined with simple assembly, the side parts () are releasably fastenable in a positive-locking manner in cavities in the conveyor floor of the trough element.
