  • Patent number: 11104556
    Abstract: A wireline assembly enclosure. The wireline assembly enclosure has a first half and a second half which define an interior compartment. The first and second halves are attached via a hinge and move from an open configuration to a closed configuration. The enclosure also has a plurality of apertures. In various embodiments a stuffing box, lubrication tubing, and other materials pass through the apertures into the interior compartment. A sealing material is disposed partially about a perimeter of the first and second halves such that a seal is formed when the two halves are together in the closed configuration. The sealing material is also disposed about a perimeter of the plurality of apertures. An adjustable bar clamp inside the interior compartment of the enclosure clamps hardware in place. The enclosure is secured around a stuffing box and sheave in order to contain overspray from a wireline.
