Abstract
Mining apparatus comprises two rigid elongate members joined together in an articulated manner and a signalling device arranged to provide information dependent upon the relationship of one of the members with respect to the other of the members. The invention is particularly applicable to measure the relationship between adjacent pans and an articulated mine conveyor, for example to assist in the alignment of the conveyor. The signalling device may have two base members which, in use are respectively bolted to two adjacent pans of an articulated conveyor. Relative movement between the members is translated by components into movement detectable by rectilinear potentiometers.
Claims12
Mining apparatus having two rigid elongate members and a joint joining the members together in an articulated manner, said members comprising adjacent pans of an articulated mine conveyor, and a signalling device for assisting in the measurement of the alignment of the conveyor, the signalling device producing a signal the magnitude of which varies with the angular displacement between the adjacent pans.
