Definitions

  • the present invention relates to a container for a bulk material, and more particularly to a container for bulk material that comprises at least one pivotable door and at least one retardation mechanism, wherein the retardation mechanism is operable to slow a pivotable motion of the door.
  • each bulk material loading system comprises a square or rectangular skip, wherein the bottom of the skip is formed from a plurality of doors. During operation of the bulk material loading system, the doors that form the bottom of the skip remain closed, allowing the skip to be filled with bulk material such as building aggregates or waste materials.
  • the skip is lifted by a crane, moving the skip, and the bulk material contained therein, to a position where the bulk material may be dispensed onto a waiting train or lorry.
  • This dispensing process is initiated when the doors that form the bottom of the skip are opened, under the control of the crane operator.
  • the skip doors are constructed and connected to the sides of the skip to ensure that both the weight of the skip itself, and the weight of its contents, prevent any accidental discharge of the bulk material.
  • one end of each door is connected to a side of the skip with a hinged connection, such that each door depends downwardly from a side of the skip.
  • the skip is coupled to the crane with chains connected to attachment points located at a second end of the doors themselves.
  • the weight of the skip and its contents are transferred to the crane through the doors.
  • the force exerted by the crane on the second end of the doors pulls these doors upwards, ensuring the doors remain closed whilst the skip depends from the crane. Therefore, any accidental discharge of the skip's contents is prevented.
  • unloading gantries are most usually formed from a framework of beams capable of supporting both the weight of the skip and its contents.
  • Each unloading gantry is located in an area where it is desirable for a skip to discharge its contents, and may be sized appropriately to contain a lorry or train carriage.
  • the crane lowers the skip such that projections extending from the sides of the skip are lowered on to the unloading gantry.
  • the weight of the skip is transferred from the crane to the unloading gantry itself, removing the force that ensures the doors remain in the closed position.
  • the chains coupling the doors of the skip to the crane continue to be lowered, and the doors of the skip begin to open under the weight of the bulk material, allowing the skip to dispense its contents into the area below the unloading gantry.
  • a container for a bulk material comprising a container body comprising at least one container side; and at least one aperture; said container body further comprising at least one door moveable between a first position in which said door substantially occludes said aperture, and a second position where said aperture is substantially open; further wherein said door is hingeably connected to said container side so as to be pivotable between said first position and said second position; said container further comprising at least one lifting member connected to said door; said container further comprising at least one retardation mechanism connected to said lifting member or door; wherein said retardation mechanism is operable to retard a pivotable movement of said door.
  • a container for bulk material that can deposit the bulk material it contains without the use of an unloading gantry.
  • the provision of a retardation mechanism allows the movement of the doors of the container to be slowed, allowing for either the controlled release of material from the bulk container or, alternatively, the controlled closing of the container doors when the container is lifted by a crane.
  • said retardation mechanism is operable to retard said pivotable movement of said door from said second position to said first position. In this way the movement of the door to occlude the aperture is slowed.
  • a period of time is provided during which, after lifting, the container may be moved away from the deposited material. As such, this time period may be used to move the container sufficiently such that the doors do not impinge on the deposited material as they close.
  • the present invention provides a container for bulk material that may be used to deposit material directly into a truck, lorry, train carriage, or directly onto the ground, without the use of an unloading gantry.
  • movement of the doors can optionally be stopped by the retardation mechanism, wherein the doors are held at any intermediary position between said first position and said second position for a period of time.
  • the intermediary position and the period of time is to be determined by a controller which may be human or automated.

This upwards force creates a concomitant increase in the tension in the first lifting member 180 and subsequently the first bifurcate section 182.
  • This tension or load on the first bifurcate section 182 places a load on the first door 120, resulting in its upward motion.

In this way the response time of the retardation mechanism 230 may be adjusted to ensure it is appropriate for the deposition of material to be undertaken.
  • a lower response time for the retardation mechanism 230 may be required when depositing bulk material directly onto the ground, as opposed to where material is being deposited into a train carriage and the container for bulk material 100 is resting on the support members 170

  • the attachment member 318 of the embodiment depicted in Figure 5 is raised, by for example a crane, and as such the uppermost surface of the hydraulic cylinder 304 is in a terminal raised position.
  • the attachment member 318 of the embodiment of Figure 6 is lowered, causing the uppermost surface of the hydraulic cylinder 304 to become lowered.
  • the uppermost surface of the hydraulic cylinder 304 in Figure 6 reaches a terminal lowered position since the lowermost surface of the hydraulic cylinder 304 abuts a lower surface of the housing 316 comprising the retardation mechanism 302, or an interior surface of the hydraulic cylinder 304 abuts an interior movement inhibition mechanism such as, for example, a piston coupled to the rod 306.
  • the retardation mechanism 302 of Figure 5 and Figure 6 is shown in more detail in Figure 7, which depicts a cross-section configuration of the retardation mechanism 302.
  • the hydraulic cylinder 304 is enabled to reciprocally move along the hydraulic rod 306.
  • the hydraulic rod 306 comprises a piston 320 positioned at the centre of the length of the hydraulic rod 306, which is arranged to define a maximum travel distance for the hydraulic cylinder 304 in either direction along the hydraulic rod 306. Upward and downward forces impinging upon the lifting members 310, 312 are arranged to cause corresponding movement of the hydraulic cylinder 304 in situations where a manual override is not engaged.
  • Manual control of movement of the hydraulic cylinder 304 in either direction along the hydraulic rod 306, which may occur remote of the container for bulk material 300, is performed in the embodiment shown by controlling the flow of hydraulic fluid between upper 322 and lower 324 compartments within the hydraulic cylinder 304 defined by the piston 320.
  • the container for bulk material 304 may be as shown in Figure 8, and filled with bulk material. This can be used for stockpiling containers for bulk material ahead of removal from a site, or for resting said container for bulk material on a floor.
  • the lifting members 312 coupling the uppermost surface of the hydraulic cylinder 304 to the doors 314 are slack and as such lifting of the container 300 would cause opening of the doors 314 and the spilling of container contents from the doors 314.
  • Controlled movement of the hydraulic cylinder 304 from a terminal lowered position to a terminal raised position causes the lifting members 312 coupling the uppermost surface of the hydraulic cylinder 304 to the doors 314 to become taut and as such keeps the doors 314 in the first closed position while the attachment member 318 is raised, by for example a crane.
  • the doors 314 are inhibited from opening and as such the contents of the container 300 are not spilled from the doors 314.
