Cradle for proppant container having tapered box guides
Embodiments of the present disclosure include an apparatus to support a proppant container including a frame to receive and support the proppant container, the frame having a top surface that receives and positions the proppant container above a conveyor to carry proppant disposed thereon away from the proppant container. The apparatus also includes a box guide assembly positioned on the top surface including a corner assembly having two wall segments, and a guide member extending upwardly and positioned adjacent the corner assembly, the guide member including tapered portion of the guide member, the taper having a first width at a top portion of the guide member smaller than a second width at a bottom portion of the guide member. The tapered portion contacts and directs the proppant container to a desired location.
1. An apparatus to support a proppant container, the apparatus comprising:
a frame to receive and support one or more proppant containers, the frame having a top surface to receive and position the one or more proppant containers in an elevated position; and
a box guide assembly positioned on the top surface, the box guide assembly comprising:
a corner assembly having two wall segments positioned substantially perpendicular to one another and connected to each other along a common vertical edge portion of each respective one of the two wall segments, the corner assembly also extending upwardly from the top surface and positioned on a peripheral edge of the frame to at least partially define a desired location for positioning the one or more proppant containers; and
a guide member extending upwardly and positioned substantially perpendicular to the top surface, the guide member positioned adjacent the common vertical edge portion of the corner assembly, the guide member including a tapered portion extending distally from the top surface such that a first width of the tapered portion at a top portion of the guide member is less than a second width of the tapered portion at a bottom portion of the guide member, the tapered portion contacting and directing the one or more proppant containers to the desired location when the proppant container is being positioned thereon.
2. The apparatus of claim 1 , comprising an inclined edge of the tapered portion, wherein the inclined edge extends between a proximal side of the guide member and a distal side of the guide member, the inclined edge being downwardly sloped and extending from a periphery of the frame toward the desired location.
3. The apparatus of claim 2 , wherein the inclined edge extends from the top portion of the guide member to a first end of the bottom portion of the guide member, the inclined edge extending laterally away from the proximal side, and the guide member being bound by a periphery of the frame.
4. The apparatus of claim 1 , wherein the box guide assembly comprises at least two box guide assemblies positioned at corners of the desired location, the guide members of the box guide assemblies arranged such that alignment of the container relative to the desired location is adjusted in at least two axial directions via the box guide assemblies.
5. The apparatus of claim 1 , wherein the guide member is integrally formed with at least one wall segment of the corner assembly, the guide member being positioned closer to the desired location than the at least one wall segment.
6. The apparatus of claim 1 , wherein the box guide assembly comprises a second tapered portion arranged substantially perpendicularly to the tapered portion, the tapered portion positioned along one wall segment of the corner assembly and the second tapered portion positioned along the other wall segment of the corner assembly.
7. The apparatus of claim 1 , where a first width of the guide member is less than a wall width of the wall segments of the corner assembly.
8. The apparatus of claim 1 , wherein a first thickness of the guide member is less than a wall width of the wall segments of the corner assembly and less than a support member thickness of the frame.
