With A Curved Guide Or Support Patents (Class 198/591)
  • Patent number: 9828183
    Abstract: A locking device for a material conveyor includes a snapping part pivotally connected to a first conveying section or a second conveying section of the material conveyor and capable of pivoting in the pivoting direction of the second conveying section, the snapping part being provided with two hooks; a first post and a second post that are arranged on the second conveying section or the first conveying section not pivotally connected to the snapping part and are used for being matched with the hooks in hooking to fix the relative position of the second conveying section and the first conveying section when the second conveying section is in a folded or unfolded state; and a first power mechanism used for driving the snapping part to pivot.

  • Patent number: 7040477
    Abstract: A transport system for transport of containers has a switch with an entry zone, an exit zone with at least two different transport paths for conveying a container, and a switch mechanism for selectively controlling the transport of the container to the transport paths. During their travel, the containers are supported by a support assembly, and aligned and advanced in a controlled manner in the entry zone by an alignment and propulsion mechanism. A propulsion and guide assembly in the exit zone is rendered operative in response to a transport of the container along the transport paths and includes at least two modules which respectively cooperate with the transport paths and are disposed in the exit zone below the plane of the support assembly. The modules are hereby so controlled that only the one of the modules is raised into a plane above the plane of the support assembly, when the container is transported along the associated transport path.

  • Patent number: 5161670
    Abstract: An auxiliary conveying apparatus for receiving and conveying mined material from a bridge conveyor that is pivotally attached to the discharge end of a mobile articulated conveyor. The apparatus includes an endless belt conveyor that is disposed at an angle between the first and second stationary conveyors that intersect at right angles to one another. First and second guide rails are provided to guide the bridge conveyor at a predetermined height along the first and second stationary conveyors. Third and fourth guide rails are provided to guide the discharge end of the bridge conveyor in a curvilinear path at a second predetermined height above the endless belt conveyor. Hinged transition guides are attached to the ends of the fourth guide rail to create a ramp between the first and fourth guide rails while a fixed guide rail section creates a ramp between the first and third guide rails.

  • Patent number: 4082181
    Abstract: A column disposed at the center of a circular track carries a first rocker, which is provided with first roller means. An outer support is movable on wheels along said truck and carries a second rocker, which is provided with second roller means. A bridge extends between said column and said outer support and has a length which exceeds the distance between said rockers and comprises an enclosure that extends virtually throughout the length of said bridge and defines therein a peripherally enclosed cavity. Said enclosure comprises a top wall formed with a slot which extends from a point near said column away from the latter and is adapted to be closed by a cover. An endless belt conveyor is arranged in said cavity and adapted to be charged through said slot with material to be loaded. Shifting means are operable to shift said bridge in its longitudinal direction.
