Abstract

The present invention discloses a cable tray assembly for a drilling rig or other vertical structure. In one embodiment, an extendable cable tray assembly is provided for retractable attachment to a section of a mast of a drilling rig. The cable tray assembly includes an upper tray connected to the mast in a stationary relationship. A center tray has a pivot end pivotally connected to the mast, and an articulating end rotatable between a stowed position and a deployed position below, and offset to, the upper tray. A lower tray has an upper end and a lower end. The upper end is pivotally connected to the articulating end of the center tray. The lower tray is movable between a stowed position and a deployed position below, and offset to, the center tray. An actuator is provided such that extension and retraction of the actuator results in deployment and retraction of the cable tray assembly.

Description

technical field [0001] Embodiments of the present invention relate to a novel retractable cable tray system for the transportation of cables used in connection with large vertical structures where transportation of the structure requires disassembly and separate transportation. In particular, the present invention is applicable to the rapid and safe consolidation of a large number of cables associated with a drilling rig derrick so that these cables can be retracted for transport with a single derrick section of the drilling rig without requiring multiple disconnections of the cables or for Wrap the cable for transport. Background technique [0002] In some industries, it is a common requirement to transport very long and very heavy structures across national and state highways. As a particular example of this need, in the exploration of oil, gas and geothermal energy, drilling operations are used to form boreholes or wells in the formation. Drilling rigs used in subsurfac...
