Abstract
A retaining member 16 is provided for use with a frame 10 for packaging elongate members, such as sections of drill pipe. The retaining member 16 comprises a pressure plate 18 on which is mounted a pair of pivoting hooks 20 for engaging with protrusions 36 formed on the frame 10. The hooks 20 are connected to threaded rods 28 received in a sleeve 30. A ratcheted handle 34 allows selective rotation of the sleeve 30 to draw the rods 28 therein, and so to pivot the hooks 20 to urge the pressure plate 18 against members received within the frame 10. A quick release mechanism is provided to allow easy release of the hooks 20 and the retaining member 16.
Claims20
Apparatus for packaging elongate members, the apparatus comprising:
- a frame comprising a base and side members;
- at least one packing member engageable with the frame, the packing member having a deformable portion for engaging elongate members to be handled;
- and means for retaining the packing member in contact with the elongate members, the retaining means comprising a pressure plate for urging the elongate members into contact with the packing member, engaging means for engaging a portion of the frame, and an adjustable tension member connected to the engaging means, the engaging means being mounted on a pivot on the pressure plate such that an increase in the tension applied by the tension member causes the engaging means to pivot and be urged against said portion of the frame.
Apparatus for applying a compression force to a member held within a frame, the apparatus comprising a pressure plate, engaging means for in use engaging a portion of a frame, and an adjustable tension member connected to the engaging means, the engaging means being mounted on a pivot on the pressure plate such that an adjustment in the tension applied by the tension member causes the engaging means to pivot.
A method of applying a compression force to elongate members held within a frame, the method comprising the steps of:
- providing a pressure plate, engaging means mounted on a pivot on the plate, and an adjustable tension member connected to the engaging means;
- engaging the engaging means with a portion of a frame;
- and
- adjusting the tension member to exert increased tension on the engaging means.
Apparatus for applying a compression force to a member held within a frame, the apparatus comprising a pressure plate, at least two engaging means for, in use, engaging respective portions of a frame, and at least two adjustable tension members each connected to a respective engaging means for applying a holding force to the engaging means, the adjustable tension members being operatively associated such that the force exerted on each engaging means by each tension member is substantially equal, and the engaging means being mounted on respective pivots on the pressure plate such that a variation in the force applied by the tension member causes the engaging means to pivot and be urged against a portion of a frame.
Apparatus for applying a compression force to a member held within a frame, the apparatus comprising a pressure plate, at least two engaging means for, in use, engaging respective portions of a frame, and an adjustable member connected to at least one of the engaging means for applying a force to the engaging means, the engaging means being mounted on respective pivots on the pressure plate such that an adjustment in the force applied by the member causes the engaging means to pivot, and the engaging means being operatively associated with one another and with the member such that the force exerted on each engaging means by the member is substantially equal.
Apparatus for applying a compression force to a member held in a frame, the apparatus comprising a pressure plate, at least two engaging means mounted on the pressure plate and for, in use, engaging respective portions of a frame, and an adjustable member for variably applying a substantially equal force to each engaging means, to urge the engaging means against the respective portion of the frame and so urge the pressure plate against a member held in the frame.
Apparatus for applying a force to a member held in a frame, the apparatus comprising at least two spaced portions for urging against a member, each portion comprising an engagement means for engaging a portion of a frame;
- the apparatus further comprising variable force means for variably applying a substantially equal force to each engagement means;
- wherein the engagement means are urged against the portion of the frame to a degree proportionate to the force applied by the force means, each engagement means serving to urge a respective spaced portion against a member.
