DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a fixing device for securing elongate articles, such as conduits, to support structures, in particular cableways/cable risers.
When mounting elongate articles such as conduits on underlying support structures such as cableways and cable risers, in structures at sea and on land, the conduits are secured and held in place by means of conduit clamps. In their simplest form, such clamps consist of a u-shaped body attached by the side edge at the bottom of the U-opening to the support structure by means of screws and nuts or by means of hooks which are brought into engagement with holes, slots or edges in the support structure.
Conduit clamps of this kind ought to be easy to mount to the underlying support structure and also ought to be easy to release to enable a change in position or the removal of the clamps to be carried out during the relaying of pipelines or the moving thereof, and optionally for installing cables which require other fixing devices.
SUMMARY OF THE INVENTION
The objective of the present invention is thus to provide a fixing device in the form of a clamp which firstly can easily be adapted to different conduit dimensions and where the securement and release of the conduit are such that the objective of providing a clamp which is easy to mount on the support structure and is also easy to dismount therefrom is attained.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will be explained in more detail hereinbelow with reference to the attached drawings which illustrate an exemplary embodiments of the fixing device according to the invention and which also show how the device is mounted and how the conduit is positioned in the clamp of the fixing device.
Reference is now made to the drawing wherein:
FIG. 1 is a perspective view of a first embodiment of the fixing device seen at an angle from above with the jaw and the ratchet arm taken apart from one another and with the resilient movable attaching member locked in the engagement position by means of an eccentric member turned to the closure position by means of an operating arm, the operating arm also being indicated in dotted lines with the eccentric member in the passive position.
FIG. 2 shows the same embodiment as FIG. 1 albeit with a different design of ratchet arm, with the ratchet arm mounted in the passive position and operating arm in the upwardly pivoted passive position.
FIGS. 3a and 3b illustrate the FIG. 2 embodiment of the ratchet arm in perspective seen from above and below, respectively.
FIGS. 4a and 4b perspective views of the locking member seen looking towards the locking teeth and seen from behind.
FIG. 5 depicts the clamp of the fixing device in section seen looking towards the main surface of the clamp and the clamp opening and with the ratchet arm and operating arm of the attaching member in passive positions.
FIG. 6 illustrates the fixing device mounted on an underlying support structure in the form of a cableway, a fragment of which being shown in cross-section, with the operating arm in the active position and with the conduit positioned in the clamp opening and with the ratchet arm in the active position for retaining the conduit, and also a further fixing device mounted on top of the first fixing device with a conduit placed therein that is of smaller dimension than the first-mentioned conduit and with the ratchet arm in a second active retaining position.
FIGS. 7a, b, c, d and e illustrate as follows:
FIG. 7a the fixing device in perspective in the passive position ready for mounting onto the cableway,
FIG. 7b the fixing device mounted by means of attaching members in slots in the cableway and with the operating arm in its upper, passive position, but about to be pivoted down to hold the first attaching member in the form of a hook in engagement with an edge of a slot while the second attaching member, in the form of a hook, is in engagement (not shown) with the edge of a second slot parallel to and spaced apart from the first slot,
