Heat trace or control cable support with insulating jackets
View Patent ↗A structure is provided that applies support to wiring such as heat trace wiring to the joints and elbows of a marine arm allowing enough flexibility to avoid significant friction in the wiring while accommodating movement of the joints. A removable insulation blanket having internal retention members of wire positioning is wrapped around the joints of the marine arm and the wiring is looped outside the insulation blanket and over the joints to prevent unnecessary friction rubbing of the wiring due to joint movement.
1. An insulation blanket assembly intended for use with a terminal and loading dock piping assembly wherein the piping assembly consists of straight conduit and curved conduit interconnected by joint assemblies designed to allow relative movement between the straight conduit and curved conduit, thereby accommodating vertical movement of the loading dock with respect to terminal, the insulation blanket assembly being comprised of:
insulation blanket segments designed to accommodate and wrap each portion of straight conduit and curved conduit, wherein each insulation segment is removable from its respective conduit without destroying the integrity of the insulation segment;
each insulation blanket segment having an exterior surface and an interior surface, the interior surface including retention members designed to be removably engaged with and support wiring, whereby when the insulation blanket segment is engaged with its respective conduit, the wiring is supported proximate the surface of the respective conduit;
each insulation blanket segment further including distinct wiring entrance and exit openings extending through the insulation blanket segment from the interior surface to the exterior surface wherein wiring enters the insulation blanket segment from the exterior surface, is retained on the interior surface insulation segment proximate the surface of the respective conduit and exits the insulation blanket segment, returning to the exterior surface.
2. The insulation blanket assembly of claim 1 wherein each blanket segment includes a plurality of fastener members intended to securely fasten each blanket segment about its respective conduit.
3. The insulation blanket assembly of claim 1 wherein two insulation blanket sections are located on opposing sides of a joint assembly and the wiring exits the first insulation blanket section, loops over the joint assembly and enters the adjacent second insulation blanket assembly.
4. The insulation blanket assembly of claim 1 wherein the wiring is heat trace wiring designed to apply heat to the surface of the respective conduit.
5. The insulation blanket assembly of claim 1 wherein the wiring is control wiring for the terminal and loading piping assembly controls.
6. The insulation blanket assembly of claim 1 wherein the wiring is retained in position by the retention members of each insulation blanket section and when the insulation blanket section is removed from its respective conduit, the wiring is also removed and retained in position in the retention members.
