Description
2~ ~22~1 ., , 63-1 t316 GUIDE DEVICE AND REPLACFABLE CONNECTIOIN
;~END FOR OFFSI 3ORE HOSE ENDS
., SBACKGROUND C)F THE INVENTION
,i Thls invention relates to connectors for high pressure flexible hoses for use on an offshore rig, and more particularly, to metal-to-metal seal flange 7 and clamp hub connectors.
High pressure hoses used in offshore oil rig operations often require 'Jl~ metal-to-metal sealing and strong connectors that can quickly and easily be made up. Hoses that typically weigh as much as 6,000 Ibs. are connected to offshore rigs. Because of the large weight of such hoses, connectors are ~5 often damaged when the hoses are being moved into alignment for connection. Present connectors often lack a guide device to aid in aligning hoses for connection. When damage to a connector of such a hose occurs, repair of ~he connector usual!y involves c~tting the damaged connector ~rom the hose, machining a bevel on the hose end, and welding a new or repaired connector to the prepared hose end. In such repair operations and in general handlin~, loose parts are easily lost and dropped parts represent a safety hazard.
Examples of prior art devices for connecting pipe elements are .~5; 20 disclosed in U.S. Patents 4,927,192 and 4,867,483, which are incorporated by reference herein. Neither of these devices provides guide means to aid in aligning hoses for connection.
SUMMARY OF THE iNVENTlON
The present invention discloses a connector for cQnnecting high 2 5 pressure hoses to offshore rigs that solves the problems mentioned above.
The connector includes a guide shoe that is fixed to the end of a flexible high ~ pressure hose. The member to which the hose is to be connec~ed has a 3~5~ cylindrical adapter assembly. The guide shoe has a portion that is conical in ~,5~ shape and has a large diameter tha~ is substantially greater than the diameter ~: 3 0 of the adapter assembly. The conical portion has a small diameter that is slightly greater than the adapter assembly. The guide shoe has an aclditional :, ,,, ~! 3 5 ,, .
., ~ 2102281 ^, cylindrical section that extends from the small diameter conical portion. The cylindrical section is fixed to the end of the hose.
The cylindrical section of the guide shoe is fixed to the end of the hose using set screws to fix the guide shoe to a securing nut such as a single DYNETOR nut (U.S. Patents 4,867,483 and 4,927,192). The securing nut is welded to the end of the hose.
The end of the hose to which the guide shoe is fixed is lowered into position with the member to which it is to be connected. As the guide shoe and hose are moved toward the member for connection, the large diameter 0 end of the conical portion receives the cylindrical adapter assembly. As the guide shoe is moved closer taward the member for connection, the adapter assembly is engaged by the increasingly smaller diameter of the conical portion until the hose is properly aligned with the member for connection.
.~ Then the guide shoe is rotated to screw the securing nut onto a threaded portion of the adapter assembly to complete the connection.

2 o FIG.2 is a side elevation, partly in section, of the hose connection of FIG.1 shown after completion of the connec~ion.
DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG.1 discloses a connection of a hose end to a cylindrical member -prior to completion. A hub 2 is welded to a flexible hose (not shown) at the 2 5 end of the hose to be connected. Hub 2 has a groove 3 for receiving a loadelement segments 4. First securing nut 5 is secured to hub 2 through load element segments 4. First securing nut 5 has a grooved portion 6 for receiving load element segments 4. First securing nut 5 has internal threads 7 for threaded engagement with external threads 8 of adapter assembly 9.
3 o A guide shoe 10 is attached to and around first securing nut 5 by set screws 11. Guide shoe 10 has an internal shoulder 12 for engaging an end of the first securing nul: 5. When set screws 11 are in place/ guide shoe 10 and first securing nut 5 are rotationally fixed.
