Abstract

A hose (12) is provided with a lifting collar (10), one end of the hose including a hose end connector (26) having a central portion (34), a hose nipple (32) at the free end of the connector and a hose union portion (36) for connection with the hose body (28) at the other end of the connector. The lifting collar (10) comprises a collar member (16) for location over the central portion (34) and dimensioned to allow the collar member to rotate thereon, and a shackle (18) pivotally mounted to the collar member. <IMAGE>

Description

HOSE LIFTING COLLAR This invention relates to a hose lifting collar such as is used for lifting the ends of bulk loading hoses used for conveying fuel, oil, water and drilling fluid from supply vessels to offshore oil production platforms, exploration rigs and dock installations.
Lifting attachments are provided at the ends of bulk loading hoses to receive the hook of a crane so that the end of the hose may be lifted to and from appropriate connections. Simple lifting attachments may be formed from a length of steel which has been bent into an appropriate form, though UK Patent GB 2 148 243 B discloses an improved form of hose lifting member comprising a one-piece, die-stamped fabrication having a flat body portion defining an aperture to receive the nipple end of a marine hose, a first eye formed in the same plane as the body portion and a further eye on the other end of the body in a plane substantially perpendicular to the body portion. In use, the hook of a crane may be located in the most appropriate eye to enable the hose to be manoeuvred to the desired position.
However, the location of such a lifting member on the end of a hose requires the provision of a separate clamp, and the application of a lifting force to the member other than in the vertical direction will result in considerable bending stresses being applied to the member and the nipple end of the hose.
It is among the objects of the present invention to obviate or mitigate these disadvantages.
According to one aspect of the present invention there is provided a hose lifting collar comprising: a collar member for location on an end portion of a hose and dimensioned to allow the collar member to rotate on the hose; and a shackle pivotally mounted to the collar member.
According to another aspect of the present invention there is provided a hose provided with a lifting collar, one end of the hose including a hose end connector having a central portion, a hose nipple at the free end of the connector and a hose union portion for connection with the hose body at the other end of the connector, the lifting collar comprising a collar member for location over said central portion and dimensioned to allow the collar member to rotate thereon, and a shackle pivotally mounted to the collar member.
In use, the ability of the lifting collar to rotate on the hose and the shackle to pivot relative to the collar member allows a wide variety of angles of lift to be accommodated while creating minimal bending stresses on the collar.
Preferably, the shackle is pivotable relative to the collar member at least about an axis perpendicular to the longitudinal axis of the collar member and hose.
Preferably also, the hose union portion of the hose end connector is of lesser diameter than the central portion, to allow the collar member to be passed over the union portion onto the central portion. Most preferably, the hose nipple is of greater diameter than the central portion and the hose body is secured over the union portion by a ferrule of greater diameter than the central portion, and both the hose nipple and ferrule are of greater diameter than the internal diameter of the collar member such that, in an assembled hose, the collar is retained on the central portion between the hose nipple and the ferrule. This arrangement allows secure mounting of the collar on the hose without the requirement to provide separate clamps and the like.
These and other aspects of the present invention will now be described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is a half sectional view of a hose lifting collar, in accordance with a preferred embodiment of the present invention, located on the end of a bulk loading hose; and Figures 2 and 3 are side and end views of the hose lifting collar of Figure 1, shown somewhat enlarged.
The drawings show a hose lifting collar 10 in accordance with a preferred embodiment of the present invention mounted on the end of an assembled bulk loading hose 12, shown located in a female connector 14. The collar 10 comprises a cylindrical collar member 16 and a shackle 18 pivotally mounted to the collar member. The shackle 18 is provided with a safety pin 20 which extends through an aperture 22 in a web 24 which extends from the collar member 16, the pin 20 and aperture 22 being arranged to permit the shackle 18 to rotate through 1800 about an axis perpendicular to the axis of the collar member 16 and hose 12.
The hose 12 comprises a hose end connector 26 held on the end of the hose body 28 by a ferrule 30. The connector 26 has a hose nipple 32 at the free end, a cylindrical central portion 34, on which the collar member 16 is mounted, and a hose union portion 36 which extends into the end of the hose body 28. The internal diameter of the collar member 16 is slightly greater than the diameter of the central portion 34 such that the collar 10 is rotatable on the end of the hose. Also, the hose union portion 36 is of lesser diameter than the central portion 34 such that the collar member 16 may be slipped onto the hose end connector 26 before assembly of the hose. On the assembled hose 12, the collar member 16 is retained on the central portion 34 by the larger diameter hose nipple 32 and ferrule 30.
The collar member 16 is formed of steel, in this example BS 4360 40A with passivated finish, which has been drop hammer forged and machine finished.
In use, the collar is free to rotate relative to the hose avoiding the application of twisting forces to the hose when it is lifted by the collar and further the pivotal mounting of the shackle relative to the collar member accommodates situations where a lifting crane is not directly above the end of the hose and avoids the application of large bending stresses to the collar member and central portion of the connector, which could otherwise result in wear and damage to both.
It will be clear to those of skill in the art that the above described hose lifting collar is merely exemplary of the present invention and that various modifications and improvements may be made thereto without departing from the scope of the invention.

Claims (8)

1. A hose lifting collar comprising: a collar member for location on an end portion of a hose and dimensioned to allow the collar member to rotate on the hose; and a shackle pivotally mounted to the collar member.
2. The hose lifting collar of claim 1 wherein the shackle is pivotable relative to the collar member at least about an axis perpendicular to the longitudinal axis of the collar member and hose.
