  • Sensing device for a rock bolt
    Patent number: 11131191
    Abstract: Rock bolts are typically used to provide support for rock formations and to hold the formation together. Rock bolts may fail due to a number of reasons. Failures in rock bolts may cause overload or loss of preload in the rock bolt. Aspects of the disclosure provide a sensing device for a rock bolt. The sensing device includes a spacer and at least one load sensor. Each said at least one load sensor includes a respective resilient compressible element that is adjacent a respective end of the spacer. The resilient compressible element compresses responsive to a respective load threshold. Each load sensor provides respective sensor output as a function of whether or not the respective resilient compressible element is compressed. The sensing device generates device output indicating a status of the rock bolt.
