Description
WO 2012/051655 PCT/AU2011/001332 - 1- Cable Laying Device and Cable Installation System Field of the Invention The invention relates to a cable installation system, and in particular, to a method and device 5 for single and multiple cable installation system. The invention can be applied to the industrial, commercial and domestic arena for installation of various cables including high voltage power, low voltage power, extra low voltage power, communication, fire systems, data optic fibre cables. It can be applied in the domestic, 10 commercial or industrial environment, for existing plants, constructions sites, high rise buildings, houses, underground cable pulls and high voltage line installation. However, for convenience sake it shall be described herein in terms of a method and system of installation of single and multiple cables for industrial, commercial and domestic use. Background to the Invention 15 The installation of cables often requires a number of electricians. In addition to the number of electricians, inefficiency arises as the electricians must pull one cable at a time to prevent cable twisting. The disadvantage is exemplified in the industrial industry where multiple cables are required to be laid over extensive distances. The electricians are required to travel continually 20 between the start location and the end location to install multiple cables along a single cable laying route. Electricians must also take time to pull loops out around the corners of a cable laying route to allow the cable to be installed over lengths around the corners of a cable laying route. This can sometimes require at least one electrician per bend. 25 The prior art further provides for separate cable rollers. However they are time consuming to set up. Also another problem is that cables can become damaged with prior art systems and thus would require replacment. If damaged during the installation, this delays the installation process and increases costs as the cables must be removed and a new cable obtained and laid. This can impact on critical project schedules due to procurement of the cables. 30 During installation, an increasing concern is the safety of the electricians who install the cables. The use of cable winches can pose.a serious safety threat to the electrician as the prior art systems are unable to withhold the cable in a suitable manner and can result in the WO 2012/051655 PCT/AU2011/001332 -2 cable flicking out. Given the large length of cables and whip-like effect, electricians can suffer serious injuries. This is especially evident when pulling cables with winches as the winches exert more pressure on the cables than hand feed such that they are likely to "flick out" of the cable rollers with greater force. 5 The lack of safety is exemplified beyond the electrician as the exposed and damaged cables may not be identified during installation. Accordingly, it is an object of the present invention to overcome or at least substantially ameliorate one or more of the disadvantages of the prior art or provide an effective alternative. 10 It is understood that any reference herein to the term "cables", includes cables such as fibre optic cables, cables for networking and telecommunications related devices or electricity, air lines and/or hydraulic hoses and the term further applies equally to other cables, ropes or wires requiring installation along an installation route including, but not limited to, installation routes constructed by the means of cable ladder, cable tray, underground conduits or 15 surface mouton conduits. It is understood that any reference herein to a cable ladder includes, but is not limited to Kounis, Ezy Strut and Unistrut ladder or Burndy (trade marked products) and perforated tray cable trays or other systems or structure used to support insulated electric cables used for power distribution and communication. 20 Summary of the Invention The invention in one form provides a cable laying device comprising: one or more mountable cable guiding parts and a clamping means for clamping the cable laying device onto a cable ladder, wherein the one or more mountable cable guiding parts receive and guide a cable and wherein the cable laying device is able to be clamped at required positions on the cable 25 ladder or the like in a cable laying route during installation, whereby multiple cables can be laid simultaneously or can be laid around a predefined corner in the cable laying route.

Description of a Preferred Embodiment of the Invention While we have described herein a particular embodiment of the cable installation system, it is envisaged that other embodiments of the invention could exhibit any number and combination of any one of the features herein described. However, it is to be understood that WO 2012/051655 PCT/AU2011/001332 - 11 any variations and modifications can be made without departing from the spirit and scope thereof. The invention provides a cable installation system for installing cables along a cable laying route, having a plurality of components. The components can comprise any one or more of a 5 combination of a plurality brackets to form a clamping means, mountable cable guiding parts which have respective pluralities of cable guiding parts, a winch 140 and a drum 135. The cable installation system is comprised of a bracket for attaching the plurality of components of the cable laying system to the cable ladder. In a first embodiment illustrated in Figures 1 to 4, the bracket is in the form of a hinged 10 bracket 10 which comprises of a bracket shape formed by a clamping frame in which to house and become secured and adapted to a cable ladder 5 of any type and shape. The clamping frame extends from the hinge mechanism 11 at two arms, an upper arm 2 in which, in the closing position, is positioned between the ladder profile bracket 41 and the lock in mechanism 42. The lower arm 3 is positioned beneath a feature of the cable ladder 5. Such 15 a feature can include the cable ladder rung 6 or elongated bar 8 of a cable ladder. For example, the embodiment in Figure 28 attaches to a cable ladder rung 6 whilst the embodiment in Figure 29 attaches to the elongated bar 8. The hinged bracket 10 provides for a hinge mechanism 11 to allow the clamping frame to move to an opened position (Figure 1b) and from an opened position to a closed position 20 (Figure 1a). It is however envisaged that other mechanisms, such as a snap fit effect, or clamps can also be utilised. However, in the current form the use of a hinge mechanism 11 with the clamp 13 is preferred as it reduces installation time by requiring less activity and manual labour by the electrician, thus providing for a cost effective option. The hinged bracket 10 can be varied as desired or required. For example, in Figure 35, the 25 hinged bracket 10 can be mounted on items including, but not limited to, steel or concrete corners, shed perilins and timber frames. It provides for a structure modified to provide a cornered attachment that can be bolted or screwed into corners. In such an embodiment, the hinge is along the longitudinal side of the hinged bracket 10 rather than at an axial point seen in Figure 1. 30 The hinged bracket 10 provides an attachment mechanism in order to lock the upper arm 2 and lower arm 3 together by a clamp 13 however, it is envisaged that any other locking mechanism may be utilised such as a nut and bolt. In the embodiment presented in Figures 3 and 4, the top view of the hinged bracket 10, identifies a clamp receiving aperture 15 in WO 2012/051655 PCT/AU2011/001332 - 12 which such an aperture 15 allows the slideable receiving of the clamp 13 for locking into position and maintaining the attachment between the upper arm 2 and the lower arm 3. The clamping means provides a lock in mechanism between the upper arm 2 and the cable ladder 5. The flexibility of the current invention allows for the hinged bracket 10 to be 5 adjusted according to the ladder used. Therefore, the lock in mechanism can be changed to suit all types of ladders. The lock in mechanism comprises of a ladder profile bracket 41. Figures 1 and 2 illustrate two embodiments of the ladder profile bracket 41. In Figure 1 (also shown in Figure 28), the ladder profile bracket 41 is presented as round bars. In Figure 2 (also shown in Figure 29) 10 the lock mechanism is presented as a bracket complementing the cable ladder 5, particularly the elongated bar 8, and a lock block 43 is attached to the inner side of the lower arm 3 for further support and to ensure that the hinged bracket 10 is fixed securely to the cable ladder 5. The lock block 43 in the embodiment presented in Figure 2 is presented as part of the 15 hinged bracket 10. It provides a complementary interaction to the underside of the cable ladder 5 where a channel might be formed. Such a complementary interaction, as illustrated in Figure 2, can include a frictional interaction in which lock block 43 is frictionally inserted into the underside of the cable ladder 5. The ladder profile bracket 41 in both embodiments can be altered in order to suit different 20 sized and shaped cable ladders, or further altered in order to be applied to cable trays or other cable laying equipment. When locking the cable laying device securely to the cable ladder 5, the ladder profile bracket 41 allows for a complementary interaction to the lock block 43 in order to fix the upper arm to the cable ladder 5. The nut 45 and bolt 44 provide strength to the structure and 25 are situated on top of the upper arm 2 to fix the upper arm to the ladder profile bracket 41. The hinged bracket 10 can then be moved to a closed position through the hinge mechanism 11 and locked into the closed position through the use of the clamp 13. The nut 45 and bolt 44 form part of the locking attachment 42. The nut 45 and bolt 44 are used to secure the upper arm 2 to the ladder profile bracket 41 where, upon activation, is 30 fastened securely. The lock in mechanism 42 therefore provides for the removal of the ladder profile bracket 41 for one type of cable ladder and the insertion of a replacement ladder profile bracket 41 where a different type of cable ladder is used.
WO 2012/051655 PCT/AU2011/001332 -13 In use, the hinged bracket 10 can be attached to the cable ladder rungs 6. The attachment occurs as the lower arm 3 is positioned beneath the cable ladder rung 6. The upper arm 2 is lowered to a position whereby, in the embodiment presented in Figure 4, the ladder profile bracket 41 frictionally fits around a lock block 43 surrounding the cable ladder rung 6 as a 5 result of the lock in mechanism 42. Hence the second attachment mechanically locks the upper arm 2 and lower arm 3 to the cable ladder 5. In order to secure the upper arm to the lower arm, the clamp 13 is slideably moved into the clamp receiving aperture 15 and held in position as a result of the shaping and size of the clamp 13. 10 In order to remove the hinged bracket 10 from the cable ladder 5, thereby moving the hinged bracket 10 to an opened position, the opposite occurs in which the clamp 13 is slideably removed and released as the two arms of the clamping frame extend in opposing directions to release the cable ladder 5. As identified above, in order to remove the ladder profile bracket 41, for replacement with 15 another or simply for storage purposes, the nut 45 and bolt 44 are removed thereby releasing the ladder profile bracket from the upper arm. This is contrasted to the mechanism in the embodiment presented in Figures 1 where no lock in mechanism 42 is presented. In this embodiment, the arms are moved from an open to a closed position by the slideable insertion and removal of the clamp 13. The ladder profile bracket 41 is therefore in a fixed 20 position. It is therefore envisaged that the hinged bracket 10 and the components thereof can be altered depending on the use and the desires of the electrician. The embodiment in Figure 3 is presented where no lock in mechanism 42 is provided. In contrast, Figure 6 provides for a lock in mechanism 42 at two opposing ends across the 25 width of the hinged bracket 10. The embodiment in Figure 4 can be utilised when additional load bearing strength is required for larger cables and also where multiple cable rollers are required for multiple pulls at one time. The clamping means can be manufactured at any size and of any thickness, preferably of metal, to obtain the strength required for its use. In a second embodiment presented in Figures 6 to 8, the bracket is in the form of a metal 30 bracket 120. In the embodiment illustrated in Figures 6 to 8, the metal bracket 120 is in a L shape formation and comprises of a longitudinally extending member 124 and a laterally extending member 122. At the adjoining end of the longitudinal member 124 to the lateral member 122, to form the L-shape, a lower arm 126 is provided in the form of an angled plate WO 2012/051655 PCT/AU2011/001332 -14 member. As in the first embodiment, the lower arm sits beneath a cable ladder 5. The longitudinal member 124 further includes a hook 99 and the lower arm 126 also acts as a stabiliser for the metal bracket 120. This plate member slides onto the laterally extending arm and hooks onto the cable ladder to provide strength for the cable ladder and the 5 mountable cable guiding parts. In contrast to the locking mechanism of the first embodiment, this second embodiment provides for a locking bracket 102 to lock the lower arm 126 and the upper arm 104 provided by the locking bracket 102. The locking bracket is provided as two embodiments in Figures 14 and 15, where the locking bracket comprises of a central aperture 103 in which to receive 10 and be slideably inserted at one end, preferably the longitudinal member 124 of the metal bracket 120 or the longitudinal member 101 of the lower bracket 110. The embodiment in Figure 14 provides a straight locking bracket as it allows cable laying across a cable ladder laterally. The straight locking bracket has an S-shaped bar, forming the upper arm 104 that opposes the lower arm 126, and a locking mechanism comprising of 15 a handle 106 and a latch 108 in the form of a T-bar or a quadrilateral bar as shown in Figure 23a. A further lock hole 109 is provided to allow the option of fitting in a padlock or pin. This minimises or eliminates tampering by unauthorised personnel. The embodiment in Figure 15 provides a bend locking bracket for use in installing cable in a 900 direction. The bend locking bracket provides for a u-shaped holder 105 where the 20 opposing ends 105a, 105b of the u-shaped holder 105 are split and appear jagged. These opposing ends 105a, 105b form part the upper arm 104 in this embodiment opposing the lower arm 126. The remaining components are the same as the straight locking bracket depicted in Figure 14. Further to the embodiment in Figures 6 to 8, the metal bracket will further comprise of a riser 25 55. The riser 55 can be located along the lateral member 122 at an opposing side to the hook 99 and lower arm 126. The riser 55 has a relatively planar surface with a flanged end 58, the flanged end extending into an inwardly defined lip 59. The riser 55 further provides for an aperture 57 in which is capable of receiving the metal bracket 120 and moving relative to the metal bracket 120 30 according to the width of the cable ladder. The metal bracket 120, in use, is positioned underneath a cable ladder. In doing so, the riser 55 strengthens the cable ladder and clamping means.
WO 2012/051655 PCT/AU2011/001332 -15 The riser can also be used to install cables up a 900 angle along the surface of an upstanding wall. The riser 55 has a relatively planar surface with a flanged end 58, the flanged end extending into an inwardly defined lip 59. The riser 55 further provides for an aperture 57 in which is capable of receiving the metal bracket 120 and moving relative to the 5 metal bracket 120 according to the width of the cable ladder. The lower arm 126 of the metal bracket 120, in use, is positioned underneath a cable ladder 5. The locking mechanism, in the form of a locking bracket 102, described above can be further applied to a third embodiment of the bracket where the bracket is in the form of a lower bracket 110. The lower arm 132 of the locking bracket is in a form complementary to the 10 form of the upper arm 104 of the corresponding locking bracket 102, illustrated in Figures14 and 15, depending on whether the cable is to be installed laterally or at a 900 angle. The lower bracket 110 is depicted in Figures 16 and 17. The lower bracket in Figure 16 is a bend lower bracket and provides a lower arm 132 which corresponds to the bend locking bracket.in Figure 15 as both share the same jagged edge 15 feature. Therefore, the lower bracket 110 in Figure 16 provides for a u-shaped holder 105 where the opposing ends 105a, 105b of the u-shaped holder 105 are split and appear jagged. In the lower bracket the jagged edge is facing upwardly. The lower bracket 132 in Figures 17 is a straight lower bracket and corresponds to the straight locking bracket in Figure 14. Here the lower bracket provides a planar u-shape piece 20 which forms the lower arm 132 and allows for the lowermost point of the u-shape to be fitted under a cable ladder 5. The lower brackets can be fitted onto an end of the metal bracket 120 or can be stand alone. The straight locking bracket can be fitted onto bends but it is preferred that the bend locking brackets are used to provide a firm hold as a result of the jagged features. 25 In this second and third embodiment of the bracket, the bracket has a longitudinal extending member 124, 101. In the second embodiment, in the form of a metal bracket 120, the lower arm 126 is connected to the lateral member 122 of the metal bracket and forms part of the extending lateral member. The upper arm 104, in a further, can be part of the longitudinal member 124, 101 or provided as part of the locking bracket 102 in order to clamp the lower 30 arm and upper arm around a cable ladder 5. In doing so, the upper arm moves relative to the lower arm to provide such a locking feature and thereby allows the locking bracket 102 to be in a slideable connection with the lower arm 126 of the longitudinal member 124.
WO 2012/051655 PCT/AU2011/001332 -16 In the preferred embodiment, the lower arm 126 is fixed into position at a one end of the longitudinal member 124. The upper arm 104 of the locking bracket 102 is slideably and removably connected to the longitudinal member and can slide along the longitudinal member 124 relative to the lower arm 126 to provide a desired distance that will fit and 5 clamp around a cable tray or cable ladder 5. It can be seen that each of the brackets in the second and third embodiments provide a hook 99 that corresponds to a control mechanism. In the embodiment presented in Figures 21 and 23, the control mechanism comprises of a pivot member 142 having an arm 144 extending from the pivot member 142. The arm 144 10 has a latch 108 for acting as a hook receiving feature comprising of a frame 146. The frame can define an inner aperture 148 or be in an alternate formation such as a T-bar (see Figure 14a) which can be received and hooked on to by the hook 99. The inner aperture 148 is able to receive the hook 99 located on the bracket. The hooking and unhooking actions results from the pivot member 142 extending into a lock and unlock position shown in Figure 23a 15 and 23b. Figure 23b shows the upper arm in the bracket lock position. In this position, the upper arm 104 and lower arm 126 firmly support the cable ladder 5. The control mechanism has a hook 99 that is received by the inner aperture 148. The pivot member 142 is positioned linearly along the longitudinal extending member 124 and locked into position. In the embodiment 20 presented in Figure 23, the pivot member 142 is inserted between two frames 162, 164 having aligning apertures 163, 165 in which a bolt (not shown) can be threaded through to prevent the pivot member from being released. To remove the upper arm 104 from the longitudinal member 101, 124 and move the bracket into the bracket unlock position and to be further capable of slideably removing the locking 25 bracket, therefore the upper arm 104 can be removed to release the mountable cable guide 40 from the cable ladder 5. In this position, the user releases the bolt (not shown) and lowers the pivot member 142 such that the hook 99 can be released from the arm. In the embodiment in Figures 14 where the latch 108 is in the form of a T-bar, the T-bar is threaded or has a threaded section 108a. This allows the threaded T-bar to be increased or 30 reduced in height, thereby allowing the increasing or lowering of the upper arm 104 relative to the fixed lower arm 126, 132. This adjustability allows versatility to the system and apparatus allowing the clamping means to be adjusted to different width of cable ladders. This provides a time efficient means of installation.
WO 2012/051655 PCT/AU2011/001332 -17 The cable installation system also provides for a winch 140 which can be a stationary motor driven or hand-powered machine for hauling the rope around the cable laying route. Alternatively, the invention can be simply powered or pulled by an electrician. 5 The winch 140 comprises of a housing 142 containing a plurality of rotatable guides 144. In the preferred embodiment presented in Figure 10 and 11, the system provides for two rotatable guides located relative to one another such that the distance between them is sufficient to allow for a rope 4 or cable 3 to pass through. The paired rotatable guides 144 are rotatable about a central axis. The rotation can occur as a result of such mechanisms as 10 two rollers rotating around a shaft as illustrated in Figure 12. The direction of rotation is dependent on the desired direction in which the rope 4 is to pass through between the rotatable guides 144. For example, if the rope 4 is to be guiding from left to right, the rotation of the rotatable guides is in an inward direction, in a direction towards the opposing rotatable guide 144. If the rope is to be feeded from right to left, the 15 rotation of the rotatable guide 144 is in an outwardly direction, in a direction away from the opposing rotatable guide 144. The rope 4 is guiding to and from the rotatable guides 144 by a channel 146 having an inner wall 148 and an outer wall 147. The inner wall 148 defines a central aperture 149 in which the rope 4 or cable 3 is guiding through. The inner wall 148 can be further coated or 20 provided with features to assist in the frictionless movement of the rope 4 through the winch 140. For example, in the embodiment presented in Figure 11, the inner wall 148 has a TeflonTM brush. The winch 140 can be man powered or operated by a transmission or gearbox 150 to provide speed and torque conversions from the rotating power source to the rotatable guide 25 144. The winch 140 further includes an engine 152 and a power source 154 to drive gearbox 150. The winch 140 assists in keep the rope or cable tort. The winch 140 further includes a support 156 comprising of a body formed of a first part 157 and a second part 158. The first part 157 and second part 158 are separated by a pivot point 159 to provide a pivotal connection and to allow the first part 157 to pivot relative to the 30 second part 158. In doing so, the pivoting motion allows the winch 140 to be detatchably connected to a ladder or cable tray 5 along the cable laying route..
WO 2012/051655 PCT/AU2011/001332 -18 In one embodiment, the winch 140 can be fixed or inserted onto a metal bracket 120. In another embodiment, where two winches 10 are used, each winch 140 can be located at either end of a metal bracket. 120. This will require the lateral member 122 to have a longitudinal member 124 at either end. 5 The pivot point 159 can be provided with a locking bolt 162. The locking bolt 162 can be threaded through the pivot point 159 to lock the first part and second part in a particular configuration or particular distance depending on the length and thickness of the ladder or cable tray 5. The winch 140 presented allows for a continuous cable installation system as seen in Figure 10 24. This illustrates the cable drum 135 and winch 140 located at opposing ends of a cable laying route. In doing so the cable drum 135 releases the cable that is attached to a rope 4. As the rope is extended along the cable laying route it allows multiple cables to be threaded through the mountable cable guide parts 40 and enter the winch 140 such that the rope 4 returns to the cable drum 10 to attach to a second cable and thread the second cable 15 through the cable laying route. The invention further comprises of a mountable cable guiding part according to the following embodiments. In one embodiment, the mountable cable guiding part 20 can be sized and shaped according to the cable ladder and to get the cable guiding part as close to the cable ladder. The 20 installation of these mountable cable guide parts are illustrated on hinged bracket 10 but can be modified to apply to the metal bracket 120 or the lower bracket 110. In the embodiment presented in Figures 25 to 35, the cable rollers comprise of a mounting base 30, an elongated body portion 22 and a cable guiding part 40 having rollers. The mounting base 30 is positioned between the first upper arm 2 and the cable guiding part 40. 25 The mounting base 30 allows the removable attachment of the mountable cable guiding part 20 to the hinged bracket 10. The mounting base 30 comprises of an external wall 32, an internal compartment 34 further comprising of a channel 50 and a channel lock nut 52. The channel lock nut 52 rises and descends with the threading insertion of the lower end 26 of the elongated body potion 22. 30 Once in position, a further nut 56 can be used to lock the mountable cable guiding part 20 into position.
WO 2012/051655 PCT/AU2011/001332 -19 In operation of the mounting base 30, Figure 27b illustrates the motion in which the lower end 26 of the elongated body portion 22 is threaded and screwed through the channel lock nut 52. This makes the channel lock nut 52 rise from within the internal compartment 34 to slide into the channel 50 before the lock in mechanism 42 is attached. Then a nut 56 locks 5 the elongated body portion into position. Figure 27b provides a top view of the channel lock nut 52. The elongated body portion 22 provides for an upper end 24 and a lower end 26. Both the upper end and lower end are threaded. The lower end 26 is removably fitted into the mounting base 30. The threaded features allows the nut 56 to be twisted around the lower 10 end in addition to allowing the lower end 26 to be threaded into the channel lock nut 52. In the embodiment illustrated in Figure 35, the elongated body portion 22 is threaded from the upper end 24 to the lower end 26. This embodiment can be utilised in the domestic and commercial industry and, in particularly, it can be installed in items including, but not limited to, wooden frames, concrete, shed perlins and cable pits. Such an embodiment further 15 allows installation through walls and allows corner attachments and provides a 90 degree attachment bracket. The bracket can be mounted on a wall surface. The threaded bar can be used to drill roof. As the upper end 24 is threaded, the cable roller is removably fitted in a twisting action into the connecting means 61 of the cable guiding part 40.The elongated body portion 22 is 20 preferably in a linear shape however, Figure 30 illustrates that the elongated body portion 22 can be in an L shape which will assist in pulling cables from one ladder level to another ladder level as illustrated in Figures 29 and 31. Therefore, the elongated body portion can be modified in shape as desired or required. The different ladder levels are created in two forms. The first form, as illustrated in Figure 31 25 the cable ladder 5 can be arranged in multiple levels. This means that the laying route provides for an overlapping of cable ladders 5 thereby having a first cable ladder 5 placed above a second lower cable ladder 5. The second form arises where the two sides of the hinged bracket 10 are used. This is shown in Figures 28 and 29. The mountable cable guiding parts described below can be modified accordingly to be 30 applied to any one or more of the above described brackets. The invention provides a number of embodiments of the mountable cable guiding part 20. In the first embodiments described above, the mountable cable guiding part 20 is attached to the upper arm 2 of the clamping frame. However, in the embodiment allowing for different WO 2012/051655 PCT/AU2011/001332 - 20 ladder levels, the mountable cable guiding part 20 can be attached to both the upper arnm 2 and the lower arm 3, where the connection to the lower arm 3 occurs as a result of a further nut 70 that is welded onto the lower arm 3. The mountable cable guiding part can be further attached to one or more of the brackets described above. 5 The cable guiding part 40 further comprises of an opening 63 which is opened according to the opposing hinge mechanism 62. The opening 63 allows a cable to be inserted into the internal area 49 formed by the cable guiding frame 66 and the roller 68. The roller 68 secures the cable and ensures no twisting or damage to the cable during the pulling action. In one embodiment presented in Figure 32, the cable guiding frame 66 does not provide for 10 an opening or opposing hinge mechanism but a snap lock effect. In such an embodiment, the cable roller is used for smaller power and communication cables whereby the cable can be bent when the cable is to be removed. Such an embodiment is still advantageous as the cable is unable to be removed from the internal space created by the cable guiding frame during the pulling action of the cable. 15 The cable guiding frame 66 of the cable guiding part 40 can, in one form, be quadrilateral shaped as illustrated in Figure 33. However, the cable guiding frame 66 can be altered to accommodate the needs and desires of the cable laying route and the electrician. Therefore, the cable guiding frame 66 can also be presented in a U shape as illustrated in Figure 34. A second embodiment of the mountable cable guiding part 80 is illustrated in Figures 19, 21 20 to 23. The mountable cable guiding part 80 comprises of a cable guide 82 and a removable portion 48. The cable guide 82 can be in the form of a clamp as illustrated in Figure 21. In such an embodiment, the cable guide 82 has a central hole 86 (in the clamped position) and a hinge mechanism 88. 25 The cable guide 82 can be in the form of a clamp like member and be divided into an upper clamp member 92 and a lower clamp member 94. The inner lining of the upper clamp member 92 and the lower clamp member 94 can be strengthened, to prevent frictional tear with the cable. For example, it can have an inner metal lining. The upper clamp member 92 is connected to the lower clamp member 94 by a hinge 30 mechanism 88 to provide a pivotal connection. The pivotal connection allows the upper clamp member 92 to be moved in a pivotal fashion relative to the lower clamp member 94 to provide a clamping effect around a cable 3.
WO 2012/051655 PCT/AU2011/001332 -21 In the simple form presented in Figure 19, the cable guide 82 has a central hole 86 in which to allow a cable 3 to be housed and a lock to prevent the cable 3 from being released from the central hole 86. In the embodiment presented in Figure 20, the lock is formed by the over extending and overlapping end portions of the upper clamp member 92 and the lower clamp 5 member 94. This embodiment provides the further advantage of eliminating the time required for installing clamping and locking the cable guide 82. In the embodiment presented in Figures 19, 21 to 23, the lock is in the form of a latch member 96. The latch member 96 is located on the lower clamp member 94 in a pivotal manner such that 10 it can extend from an unlocked position to a locked position. In the locked position the latch member 96 slides or pivots to a position adjacent to the upper clamp member 92 and a locking pin 97 is inserted through the apertures of the latch member 96. The upper clamp member 92 can have a receiving end in the form of a Y-shaped member 98. In the locked position the upper clamp member 92 and lower clamp member 94 are clamped together 15 around a cable 3. To release the cable, the locking pin 97 is slideably removed from the y-shaped member 98 and the latch member 96 returns to its unlocked position. The cable guide 82 allows the cable 3 to be inserted through the central hole 86 in two ways. In one form, the one end of the cable 3 can be threaded through manually or by being attached to a rope 4. However, in 20 the second form, such as to replace a roller, the cable a portion of the cable can be removed or inserted into the central hole 86 by clamping and unclamping the upper clamp member 92 and lower clamp member 94. The cable guide 82 further comprises of a connecting end 48. The connecting end 48 is capable of slideably engaging with a bracket which can be shaped to have a complementing 25 receiving end. In doing so the cable guide 82 can be readily removed and installed to allow the installer to mix and match or replace the mountable cable guide parts 80 with those having different size or shaping as desired. The bracket in Figures 21 to 23 is the lower bracket 110. A similar mechanism can be applied to the metal bracket 120 or, through modifications, to the hinged bracket 10. 30 A further embodiment of the mountable cable guiding parts is illustrated in Figures 36 and 37 which comprises of a body 171 in the form of a steel plate. The figures illustrate the body comprising of a connecting end 174, an elongated body 178 and a cable guide 172.
WO 2012/051655 PCT/AU2011/001332 -22 The connecting end 174 allows the mountable cable guiding part 170 to be installed onto the longitudinal member 124 of the metal bracket 120 or bracket 110. In doing so, the connecting end 174 defines an aperture in which to slideably receive the longitudinal member 124. 5 The cable guide 172 is in the form of a nylon roller which turns around a shaft 176 as the cable 3 is pulled through a guide path 182. A further feature of adjustability and versatility is provided in the mechanism in which the mountable cable guiding parts 80 are installed onto the metal bracket 120 or lower bracket 110. It can be seen in Figure 18a that the lower bracket 11 is provided with an aperture 10 101a. This can be a single aperture or a series of apertures running along the longitudinal member. A corresponding aperture 83 is located on the mountable cable guiding part 80. The aligning allows the mountable cable guiding part 80 to be moved along the longitudinal member and positioned as desired. If desired, the mountable cable guiding part 80 can be installed upside down to the manner in which illustrated in Figure 18b. A pin (not shown) can 15 be threaded through the aperture 101a and corresponding aperture 83 to lock the mountable cable guiding part into the desired location. This advantage allows adjustability and further versatility to the apparatus and system. The cable installation system is illustrated in Figure 38. Here, the cable drum 35 is a round, drum-shaped object such as a spool used to carry various types of electrical wires. Cable 20 reels usually come in three different types, each with their own uses: wood, plywood, and plastic. Generally a reel has a cylindrical core and walls on the sides to retain the material wound around the core. In some cases the core is hollow, although other items may be mounted on it, and grips may exist for mechanically turning the reel. The cable drum is positioned at the beginning of the cable laying route and unwinds as the cable is pulled 25 during installation. A further element of the invention is illustrated in Figure 24. Here, the mountable cable guide parts are installed upside down thereby providing for a first installation route along the top half of a cable ladder and a second installation route along the bottom of the cable ladder. In doing so the mountable cable guide parts provide for a continuous loop in which a top can be 30 circulated through powered by the winch. This allows a continuous mechanism in which a series of cables can be pulled through a cable laying route. The cable ladder 5 provides a support in which and the cable laying device can be attached and further identifies the cable laying route. The cable ladder 5 is attached to the roof WO 2012/051655 PCT/AU2011/001332 - 23 trusses or other structural features. In the preferred embodiment, a cable ladder is utilised however, the cable laying device can be used in conjunction with cable trays. Cable ladders have sections normally welded rungs spaced about 300mm intervals over a 3 or 6 meter span. Cable trays are normally continually hard tool pressed to form a symmetrical pattern of 5 2.4 to 3 meter spans. The drum 135 houses the cable as it is pulled and unwound. Figure 39 and 40 illustrate the invention in use at the beginning of a cable system where a conduit 7 is used to house multiple cables 3. In such an embodiment, multiple cable guide parts 60, 82 are connected 10 together in a flower head arrangement 78 on the top of a stake 76. The cable is directed through a series of these arrangements. Each stake is set up underground or above ground. The cable is led through the flower head arrangement 78 into the conduit. The conduit 7 can comprise of an aluminium sleeve 7a that goes over the conduit to ensure that the cable does not sheer on the edges of the conduit 7. 15 The system in Figures 39 and 40 can utilises at least two or more of such flower head arrangements 78 of any size to suit installation. Where a set of two flower head arrangements are used, the first flower head arrangement 78 brings each of the cables together, the second flower head arrangement 78 provides direction into the conduit 7. A 20 jack can be used to make each of the cable drums 135 level. The invention therefore provides a method and device for cable installation that can be implemented in the industrial, commercial and domestic arena. The cable laying device can be used for all high voltage power, low voltage power, extra low voltage power, communication, fire and optic fibre cables. Within these industries, the cable laying device 25 can be utilised in numerous situations: existing plants, constructions sites, high rise buildings, houses, underground cable pulls and high voltage line installation aiming to maximise safety, eliminate cable damage, minimise labour, and to minimise twisting and intertwining of the cables to provide neatly and safely arranged cables in a cost efficient, time efficient and safe manner. 30 Those of skill in the art will appreciate that the invention is not limited to the above described embodiments but includes any modifications or changes to the particular embodiments exemplified can be made without departing from the scope of the invention. All such modifications and changes are intended to be included but not limited to the scope of the appended claims. 35
