Abstract

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.

First claim

The invention claimed is:

1. A system to store and support proppant containers, the system comprising:
a plurality of proppant containers, each of the proppant containers of the plurality of proppant containers comprising:
walls forming a periphery of the proppant container;
an upper side; and
a bottom side forming a compartment to store proppant therein, the bottom side having an outlet formed therein to facilitate removal of the proppant from the proppant container;

a cradle for receiving and supporting the plurality of proppant containers, the cradle having a plurality of cradle sections defining a desired location on the cradle associated with respective proppant containers of the plurality of proppant containers, each proppant container being positioned on a top surface of the cradle; and
a plurality of box guide assemblies positioned on the top surface of the cradle and within an outer periphery of the cradle at respective edges of the plurality of cradle sections to at least partially define the desired location of each cradle section, the box guide assemblies each having a tapered portion extending from the outer periphery and toward to the desired location to direct each proppant container of the plurality of proppant containers into the respective cradle section.

2. The system of claim 1 , comprising box guide assemblies positioned at corners of the cradle sections, the respective tapered portions of the box guide assemblies arranged in at least two different axial directions to align the proppant container within the cradle section.

3. The system of claim 1 , wherein each box guide assembly of the plurality of box guide assemblies comprises a corner assembly, the respective corner assemblies comprising a pair of walls segments positioned substantially perpendicularly to one another, wherein the respective tapered portions of each box guide assembly are arranged proximate to the respective wall segments, and the wall segments are arranged along the outer periphery of the frame.

4. The system of claim 3 , wherein the wall segments of the respective corner assemblies are utilized by adjacent corner assemblies.

5. The system of claim 1 , wherein the plurality of containers are arranged in a side-by-side configuration along the cradle, the cradle sections arranged in a spaced relationship such that each container of the plurality of proppant containers readily is removeable from the cradle without disturbing adjacent proppant containers such that the proppant stored in the respective containers on the cradle dispenses while one or more other containers of the plurality of containers are removed from the cradle.

6. The system of claim 1 , wherein the box guide assemblies comprise a first tapered portion and a second tapered portion, the first tapered portion positioned substantially perpendicular to the second tapered portion, such that the proppant containers readily are directed in at least two different axial directions.
