Embodiment Construction

[0023] In the following description, numerous details are set forth in order to provide an understanding of the present disclosure. However, it will be understood by those skilled in the art that the described embodiments may be practiced without these specific details. Furthermore, many variations or modifications may be employed keeping in mind the specific described embodiments.

[0024] Embodiments are described with reference to certain embodiments of compact hinge mechanisms for use in aggregate management equipment. Specifically, equipment for the transportation, delivery and storage of oilfield proppants is discussed that utilizes such articulation mechanisms to support joints at large base frame units that in turn support large storage silos as well as auger The auger unit to support the extension of the auger arm for proppant delivery. However, other uses of this compact hinge mechanism are possible. For example, cantilevered support frames, ramps, frac agitator a...

Abstract

An articulation mechanism for large scale mobile aggregate system equipment. The mechanism includes a screw device that is pivotally secured to an elongated portion of the equipment to drive its movement to and from a collapsed position. The screw device is driven by a screw jack and moved within a housing while the housing itself is pivotally secured to another portion of the equipment. Rollers within the housing may be used to stabilize the lateral movement of the screw device during the opening, closing or self-locking of the elongated portion by the mechanism.

Description

[0001] Cross References to Related Applications [0002] This patent document claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application Serial No. 62 / 019,294, filed June 30, 2014, entitled "CompactActuated Self-Locking Mechanism for Lifting and Lowering Heavy Articulated Structures," and The entire content of the above-mentioned provisional application is incorporated herein by reference. Background technique [0003] Exploring, drilling and completing oil and gas and other wells is often complex, time-consuming, and ultimately very costly effort. As a result, well configurations have become more complex over the years, where appropriate, to help increase access to subterranean hydrocarbon reserves. For example, oil and gas wells are frequently found at depths greater than 30,000 feet, as opposed to wells of limited depth. Additionally, today's oil and gas wells often include inclined or horizontal sections designed to target specific subsurface reserves. In f...
