Abstract
A connection system for a lid in a beacon housing. The lid is connected to the housing at a tab at a first end, after a lip of the lid is placed under a shelf at its second end. The tab has a cross-bore for receiving a connection pin through both the cross-bore and corresponding holes in the housing which form a continuous passage. The lid is placed under tension to reduce relative vibration between the lid and the housing. A set screw is placed within the tab to place a force on the connection pin. Further set screws are distributed about the lid and place the lid in tension relative to the housing. The lid can be removed by reducing the tension provided by the set screws, removing the connection pin, and adjusting the lid such that it is no longer under the shelf of the housing.
Claims18
An apparatus comprising:
- an elongate housing of a downhole tool defining a cavity, the cavity configured to receive a beacon and having an open mouth;
- a lid configured to selectively cover the open mouth, the lid extending from a first end to a second end and defining:
- a cross pin disposed through the first end of the lid configured to secure the lid over the open mouth;
- and
- a set screw having a conical end, positioned within the lid and operable to apply a force to the cross pin at the conical end.
An apparatus comprising:
- an elongate housing of a downhole tool defining a cavity configured to receive a beacon, wherein the cavity opens at an open mouth formed in the elongate housing;
- a lid configured to selectively cover the open mouth, the lid extending from a first end to a second end;
- a component configured to engage with the housing;
- a means for applying force to the component, wherein the means for applying force to the component is carried by the lid;
- and
- a plurality of set screws disposed about a periphery of the lid, wherein the plurality of set screws are movable between a first position and a second position, and wherein:
- in the second position, the plurality of set screws place the lid and the housing in tension by pushing the lid away from the housing.
An apparatus comprising:
- an elongate housing of a downhole tool defining a cavity, the cavity configured to receive a beacon and having an open mouth;
- a lid configured to selectively cover the open mouth, the lid extending from a first end to a second end and defining a longitudinal axis extending from the first end to the second end, the lid comprising:
- a tab, situated at the first end, wherein the tab is traversed by a first bore extending in a first direction, wherein the first direction is perpendicular to the longitudinal axis;
- a lip, situated at the second end, disposed within the cavity and contacting a peripheral edge of the open mouth;
- a component situated within the first bore and configured to secure the lid over the open mouth;
- and
- a set screw having a conical end, positioned within the tab and operable to apply a force to the component at the conical end.
