The drive system [108] comprises lead [140?] and follow [140?] cogwheels, each driven by a programmable logic controller [108q] and variable frequency drive-controlled electric motor [108a]. The torque applied to each of the lead [140] and follow [140] cogwheels varies as a function of loading experienced by the cogwheels [140] and as a function of the location of the cogwheels [140] relative to a gap [159] or other discontinuity in a cog rail [150] provided on a conveyor [110]. A process for moving a tripper [100] along a conveyor [110] is also disclosed. Other mobile conveying device such as mobile hoppers, maintenance vehicles, stacking machines, conveying devices, or cranes may employ the drive systems [108] shown and described.

  • Patent number: 8851271
    Abstract: Conveyor belts are made from modular links having offset forward and rearward projecting eye parts to intercalate eye parts from one belt link between eye parts with oval lateral apertures. Connecting rods inserted through aligned apertures hingedly connect adjacent links. Clips restrict lateral turning of the belt links. Clips have general U-shapes with two legs, a bridge portion end, and opposite free ends. Projecting members at the free ends have lengths parallel to the legs and smaller than the lengths of the apertures in the belt links in which the clip is to be installed, and have heights equivalent to or smaller than the heights of the aperture in the belt link in which the clip is to be installed. The lateral distance between the two legs of the U, is larger than the lateral extent of an eye part in the belt link in which the clip is installed.

  • Patent number: 8844711
    Abstract: A chain wheel arrangement for chain drives of mining machines, with a chain wheel shaft, with a chain wheel, with bearing shells receiving bearings for the chain wheel shaft, with a chain wheel-side sliding ring seal and with a bearing-side sliding ring seal. In order to improve the service life of the chain wheel arrangement, at least one of the bearings, preferably that of the movable bearing system, is arranged in a bearing bush which is arranged between the bearing shell and outer bearing ring and received in the bearing shell in an axially displaceable manner. The additional bearing bush allows the necessary gap between the rotating parts and the non-co-rotating, bearing shell-side parts to remain substantially constant and to this extent to become independent of the bearing play of the respective bearings.

  • Patent number: 8727109
    Abstract: An apparatus for conveying one or more objects along a conveying path in a conveying direction includes an endless conveyor chain formed of modular links arranged in rows in a direction transverse to the conveying direction. The links include spaced outer side links forming a part of a conveying surface for the objects to be conveyed and intermediate links interconnected with side links by connector rods, the chain having at least a forward run for conveying one or more objects in the conveying direction. A driver is provided for driving the conveyor chain, and includes a first sprocket adapted for engaging at least one side link along at least one side of the chain, the first sprocket mounted for rotation about an axis generally orthogonal to the conveying direction and the transverse direction. The sprocket may comprise a split sprocket, and may be adapted for pivoting movement.
