Abstract
An armoured flexible conveyor comprising pans connected together so that separation of the pans is prevented except when snaking-over to a new alignment adjacent a newly-cut mine face and except when the conveyor extends over humps and swillies in the mine floor, and a rigid plate secured along one side of each pan, said plate extending upwardly from said pan, adjacent pairs of pan ends being connected to each other, firstly by upper and lower joints between adjacent ends of said rigid plates, one of said joints being a universal joint and the other being a loose joint affording limited separation of said plates and pans at that joint, and secondly, by a loose joint at the other side of said pans also affording limited separation of said pans at said other side.
Claims3
An armoured flexible conveyor comprising pans connected together so that separation of the pans is permitted only when snaking-over to a new alignment adjacent a newly-cut mine face and when the conveyor extends over humps and swillies in a mine floor, wherein a rigid plate is secured along one side of each pan, said plate extending upwardly from said pan, adjacent pairs of pan ends being connected to each other, firstly by upper and lower joints between adjacent ends of said rigid plates, one of said joints being a ball joint and the other being a loose joint affording limited separation of said plates and pans at that joint, and secondly, by a loose joint at the other side of said pans also affording limited separation of said pans at said other side, wherein the ball joints are all upper joints, and longitudinal guide rods are secured to said plates and are connected by said ball joints.
