Force measuring unit and system for measuring chain forces

The present disclosure relates to a force measuring unit (200) for measuring a force applied to an individual chain link of a chain strand used in underground mining applications. The force measuring unit (200) may comprise a housing (240) having a first end configured to be contacted by a first chain link leg and a second end configured to be contacted by a second chain link leg, and a distance measuring device accommodated within the housing (240) and configured to measure an actual distance between the first chain link leg and the second chain link leg. The distance measuring device may include a first unit part (210) configured to be contacted by the first chain link leg and a second unit part (220) configured to be contacted by the second chain link leg (264). 本发明涉及种测力单元(200)，其用于测量施加于地下采矿应用中所使用的链索的单个链节上的力。测力单元(200)可以包括：壳体(240)，所述壳体(240)具有被配置为与第链节腿接触的第端和被配置为与第二链节腿接触的第二端；和距离测量设备，所述距离测量设备容纳在壳体(240)内并且被配置为测量第链节腿与第二链节腿之间的实际距离。距离测量设备可以包括被配置为与第链节腿接触的第单元部分(210)和被配置为与第二链节腿(264)接触的第二单元部分(220)。
