Abstract
The winch installation comprises a jib which is mountable on a working platform and carries a guide roller 4 for the supply cable 3 and a winch drum 5 with a drive 6. A traversing cable guide device 14 co-operates with the winch drum 5 for the constrained guiding of the cable 3 on the drum 5 which is composed of a combined cable storage reel 8 for multi-layer winding and an end layer reel 9 for single-layer winding with maximum tensile loading. The cable guide device 14 has means 15 for reversing the direction of the traverse moment, a winding layer control means and connection to the winch drum drive 6 for changes in speed and adaptations of drive output. During winding, the supply cable 3 passes from the cable storage reel 8 directly on to the end layer reel 9 which receives more cable length in single-layer winding than corresponds to the distance 7 between the surface of the water 1 and the immediately adjoining cable guide roller 4 of the jib. <IMAGE>
Description
SPECIFICATION
Winch installation for a supply cable of underwater apparatus
This invention relates to a winch installation for a single supply cable of an underwater apparatus, which can both be deposited by means of said cable from a working platform on to the surface of the water and lifted therefrom, and can also be towed or retained by such cable on or below the surface of the water, comprising a jib having a guide rollerforthe supply cable and being, in use, connected to the working platform (ship's deck or the like), a cable storage reel for multi-layer winding, a cable guide device co-operating with the cable storage reel for the constrained guiding of the supply cable during the coiling operation, an end layer reel for singlelayer winding of the cable with the maximum tensile loadings, drive means and means for the drive connection to the cable guide device, and control elements for the drive and cable guide.
The starting point is a winch installation (lowering and towing device) for underwater apparatuses.
Such a device was disclosed by the August Pahl
Company of Hamburg in 1978. The associated winch installation was supplied by the Christian Steen
Company.
In this known device the underwater apparatus is moved into the respective required position by a single cable, which also effects multiple functions in the supply and derivation of energy, operating means, controlling and measuring values, etc. Between individual high-strength traction ropes the cable also has various electric cables, hoses and capillary tubes, etc., so embedded in its cross section that they cannot be crushed even when being coiled on the winch drum. As a result satisfactory manoeuvrability can be assured with the use of a single connecting cable of this kind between the supply ship or working platform orthe like, and the underwater apparatus suspended from the supply cable.
The considerable extra costs of this special kind of cable in contrast with single cables and the heavy safety demands in operation have resulted in efforts to produce a special design of the winch system which will reduce to the minimum the risks of damage to the very expensive special cable and avoid interruptions of operations. The known winch system for such supply cables comprises two differently constructed driven and loadable winches which can if necessary be drivably connected to one another.
Disposed upstream in the unwinding direction of the cable storage winch is also a so-called friction winch which operates in the manner of a capstan and is preferably designed exclusively for a single-layer winding. The supply cable must be retained in reliable engagement with the friction winch as soon as there may be an occurrence of the maximum expectable tensile force, which is to be expected when the underwater apparatus is lifted out of the water.
The upstream connection of the friction winch ensures that the multi-layer winding on the cable storage winch is protected against the high tensile forces during the final tensile loading (with the load lifted out of the water). The single-layer winding on the end layer coil of the friction winch is meant to protect the supply cable against the high crushing and frictional loads which are set up when cables or ropes are inserted into the gaps between the next lower layers of multi-layerwindings. This ensures that the cable is treated more gently when being paid out and wound on in the critical load range (in which more than tenfold tensile forces may easily occur).
In the use of these prior art winch systems it has been found to be disadvantageous, a hindrance and expensive that valuable space on the working platform is required for the setting up of the two winches, due to the cable length required therebetween for the retention of a still permissible winding-on angle. Often smallervesseis are unsuitable for the system, merelyforthis reason.
Expensive precautions must also be taken to ensure constant tensile loads on two winches of different loading.
Another disadvantage of the prior art winch system is that the non-positive connection for the separate friction winch does not always cover precisely the same cable lengths during each coiling operation. This makes it impossible to make reliable checks on fatigue processes or on damage to the supply cable due to friction, etc. It is true that the winding of the cable on the storage winch with a coiling device provides a constrained guide as regards laterial offsetting, but hitherto it has depended on the operator and on chance at what place on the cable the friction loop is actually formed. With the prior art construction it was impossible to produce automatic overloading of the cable on the friction winch when the surface of the water was approached during recovery.
It is therefore an object of the invention to construct the winch installation more compactly and make it easierto operate, cheaper and more reliable than heretofore, without departing from the known principle of the multi-functional, coaxial supply cable or from the single-layer winding in the zone of the final tensile loading.
Accordingly, the present invention consists in a winch installation for a single supply cable of an underwater apparatus, which can both be deposited by means of said cable from a working platform on to the surface of the water and lifted therefrom, and can also be towed or retained by such cable on or below the surface of the water, comprising a jib having a guide roller for the supply cable and being, in use, connected to the working platform (ship's deck or the like), a cable storage reel for multi-layer winding, a cable guide device co-operating with the cable storage reel for the constrained guiding of the supply cable during the coiling operation, an end layer reel for single-layer winding of the cable with the maximum tensile loadings, and drive means and means for the drive connection to the cable guide device, and control elements for the drive and cable guide, characterised by the combination ofthefea- tures:
a) the cable storage reel and the end layer reel
are drivably combined into a common winch drum;
b) the supply cable passes from the cable stor
age reel directly on to the end layer reel;
c) the end layer reel receives more cable length
in single-layer winding than corresponds to the distance between the surface of the water and the
immediately adjoining cable guide roller of the jib.
The winch installation of the invention has the advantage that only one single winch is required for all lowering manouevres, without increased stressing of the supply cable.
Thus, a single-layer winding zone, no longer functioning merely on a friction winch basis, is directly so combined with the multi-layer cable store that the cable is always automatically wound on more gently when and as long as the load is outside the water and the heaviertensile loading of the cable is set up as the supporting effect of the water is eliminated.
This obviates the necessity to provide a second winch or the space which it requires on the working platform. The drive and control of the winch installation are greatly simplified. As a rule, operation does notcallfortheheavymanual labourformaintaining the frictional effect or the manual guiding of the free run of the cable between the two winches. The result is an appreciable reduction in labour costs. The risk that the tension on the cable may be increased unintentionally due to lack of attention on the part of an operator is considerably reduced.
Mechanical loading and wear processes are lessened, and safety therefore further enhanced.
Further advantages can be gathered from the subclaims. The result of the feature of claim 2 is that between the end ofthe cable store winding and the start of the zone of maximum loadability, which is formed by single-layer winding, there is no longer any comparable risk that the cable may kink or snake, as was quite possible, for example, with loose intermediate bearings and manual application to a friction winch with an unadapted diameter, for example, by the previous method.
The feature of claim 3 ensures that a cable guide device also automatically ensures optimum constrained guidance of the traverse in the trensition from multi-layerwinding to single-layer winding, with the direct combined use of the low winding-on tensile forces for the transition, without the need for direct manual assistance.
The feature of claim 4 ensures that the cable layers on the winch and the operation of the cable guide device can be reliably controlled by means of an element in any case provided, even in the zone of single-layer winding, where the risk of snaking may have very serious consequences.
The feature of claim 5 ensures that normally the winch drum drive speed is possible only when the associated zone of the reel has been reached or left.
This means that during winding-on there is no
longer any need to supervise the extended cable
lengths so as not to miss the moment of heavier
loading due to emergence and lifting from the surface of the water. The reduction in speed is now pro
duced automatically at the moment the surface of the water is approached.
In order that the invention may be more readily understood, reference is made to the accompanying drawings which illustrate diagrammatically and by way of example an embodiment thereof, and in which: Fig. 1 shows tha basic construction of a winch installation combined with a so-called lowering device for underwater apparatuses,
Fig. 2 is a cross-section through the winch drum,
Fig. 3 is a longitudinal section through the winch installation with minimal cable loading, that is when the cable is placed overthe cable storage reel, and
Fig. 4 shows the trensition of the cable from the multi-layer zone of the cable store reel to the singlelayer coiling zone of the final layer reel.
Fig. 1 shows how the water surface 1 forms the boundary of the two main loading conditions of a supply cable 3 from which an underwater apparatus 2 is suspended. The fully emerged underwater apparatus 2a produces the heaviest loading which, in dependence on water displacement and the weight of the apparatus, may be up to ten times the value of the tensile loading which may be needed with the underwater apparatus 2b fully submerged.
As a rule the supply cable 3 extends to a winch drum 5 on a working platform via a guide roller 4 which is arranged in an appropriately constructed jib arm.
The winch drum 5 is so constructed that, independently of the mode of operation of the winch drive 6, at all times the fixed end of the supply cable 3 is guided without interruption out of the winch drum 5 and always remains connected to the energy sources, measuring stations and the like, on board the supply vessel.
Fig. 2 shows by way of example a cross-section through a winch drum 5 constructed to wind on the supply cable 3 from above. Of course, without any essential alteration of the principle, the cable can also be wound on from below or with a different direction of rotation.
Fig. 3 is a cross-section illustrating in simplified form the principle of the complete winch installation.
In this case the winch drum 5 is so constructed with a common drive 6 and a traversing cable guide device 14, which can be adapted to different speeds, that a zone for single-layer winding, acting as an end layer reel 9, is combined directly (i.e. without any free intermediate space for a loose cable run) with a first winding zone for multi-layer winding, which acts as a cable storage reel 8. The transition 10 from one reel to the other is so constructed that no appreciable change in winding diameter takes place when the transition 10 is passed. To this end the common winch drum Sforthe end layer reel has an increased diameter 11, which corresponds substantially to the outer diameter of the penultimate winding layer 12 and which is also long enough to ensure for the supply cable 3 in the zone of the multi-layer winding of the cable storage reel 8 a stowage space adequate for the range of use of the respective underwater apparatus.
Of course, in cases in which although the capacity of the cable storage reel 8 must be only relatively low, but the diameter of the end layer reel 9 must not be reduced, appropriate adaptations of diameter, if necessary in the form of readily exchangeable adjusting pieces on the winch drum can also be provided in the zone of the cable storage reel.
The size of the stowage space for the cable storage reel 8 must be merely such that the penultimate winding layer 12 produces substantially the external diameter which agrees with the last winding layer 13 forthe purpose of gentle, single-layer winding on the end layer reel 9. At the transition 10, which is preferably constructed without sharp edges and in a manner particularly gentle to the material, for example, by hard rubber coatings or the like, measures are taken to ensure that the cable guide device 14, which is merely guided forwards and backwards in the zone of the cable storage reel 8, is, when the last winding layer 13 is reached or left, guided by suitable reversing elements 15, in dependence on the winding direction, beyond the transition 10 or only as far as the transition 10.To this end a separate drive facility which is independent in direction from the winch drive 6 is preferably provided for the cable guide device 14. This drive facility is so controlled, by suitable reversing elements 15, in dependence of the remaining length of the not yet wound-on supply cable 3, which should correspond at least to the distance 7 of the guide roller 4 above the surface of the water 1, as regards its direction of movement and its reversal point (at the trensition 10 or at the outer edge of the winch drum 5), and also as regards drive speed and driving force, by means of suitable operative connections and a change-over device 16, that neither the end layer reel 9 not the cable storage reel 8 are used with unsuitable speed of rotation ortensile force.
Of course, the same reversing elements 15 and change-over device 16 can also be suitably controlled via known length-measuring devices for the supply cable 3 to be paid out or wound on, without losing the essential advantages of the winch installation of the invention.
It is true that when the transition 10 is passed and in the zone of the end layer reel 9, the winch installation described and the end layer reel 9 as a rule no longer operate in the known manner as a friction winch, thus eliminating the risk that the cable may become so highly heated by friction that even water sprinkiing must be provided at that place, but nevertheless the winch drum zone provided for the end layer reel 9 can still be used as a friction winch element in this system, on condition that suitable additional steps are taken.This might, for example, be the case if during very rapid towing the retaining forces for the underwater apparatus 2 cause higher stressings than normal in the submerged condition on the supply cable 3, and moreover the depth of submersion is greater than the operative zone of the end layer reel 9 with a direct (loopless) transition 10 from the cable storage reel 8. In that case it is possible to deflect the supply cable 3, for example via a secondary drum (not shown), at any place below the last winding layer 13 (if necessary using suitable ancillary devices) and only then to guide the supply cable 3, if necessary using suitable extra manual guidance, on to the end layer reel 9, which in that case acts as a friction winch. This would afford the further advantage that although the drive of both parts of the winch drum 5 are combined in an extremely compact construction, the wrapping geometry of the single-layer winding with larger diameter, which is more gentle on the supply cable 3, can nevertheless if required still be used also for the zone of any required submersion depth of the underwater apparatus.
