DET~ILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A cable winding apparatus is generally indicated at 10 in Figure 1. The cable winding apparatu~ shown in Figure 1 includes two drums 12 and 14. The drums 12, 14 are driven independently of each other by suitable motors 16 and 18, respectively. The motors are shown schematically and generally in actual use will be operating through gear reducers. Cables 20 and 22 are wound on the drums 12 and 14, respectively, by a cable guiding apparatus generally indicated at 24. The cable guiding apparatus 24 of the present invention, has the capability oE winding two cables on the individually driven drums 12 and 14 or a single cable on either drum.
~ ach of the drums 12 and 14 are rotatably mounted on rigid supports 26, 28, 30 and 32, respectively. The drum 12 has end plates 34 and 36 which define the area of the drum 12 on which the cable 20 is wound. Similarly, the spool or drum 14 has end plates 38 and 40 which also define the area o~ which the cable 22 is wound.
The cables 20 and 22 are a braided, relatively large diameter, steel cable. In one successful application, the present invention is used to wind 5/8 inch diameter cable in a coal mine operation. The 5/8 inch cable is used to retrieve 4 , ' - ' .
,, ~2~5~3 inch diameter cable. It is important that the 5/8 inch cable is wound uniformly so that it is readily ava.ilable for subsequent operation.
The cable is wc~und onto the cdrums 12 and 14 05 in a substantially uniform manner by the cable guiding apparatus 24. ~he cable guiding apparatus 24 as illustrated in Figure 1, includes a left cable guiding mechanism 42 for guiding the cable 20 onto the drum 12 and a right cable guiding mechanism 44 for guiding the cable 22 onto the drum 14. Both the left and right cable guiding mechanisms 42, 44 receive power from a common hydraulic system 46. The hydraulic system 46 includes a reservoir 48, a hydraulic pump 50, a supply conduit 52 conveying hydraulic fluid to and a return conduit 54 conveying hydraulic fluid from the guiding apparatus 24, respectively.
Fluid is diverted to the left and right cable guidincJ mechanisms 42 and 44 through a flow divider 56. The Elow divider 56 diverts a portion of the hydraulic fluid to a conduit 58 to the leEt cable guiding mechanism 42 ancl to a conduit 60 to the right cable guidin~ mechanism 44. Hydraulic fluid flows back to the hydraulic system 46 through a conduit 62 from the left cable guiding mechanism 42 and through a conduit 64 from the. right cable guiding mechanism 44. The conduits 62 and 64 are joined by a Tee 66 which is connected to the return conduit 54~
The guiding mechanisms 42 and 44 are mirror images o~ each other and will be described with reference to right cable guiding mechanism 44 as illustrated in Figure 2. It is to be understood that like reference characters will indicate like elements ~4s;~r~53 of both left and right cable guiding mechanisms 42 and 44 as illustrated in Figure 1.
The right guiding mechanism 44 includes a guide support member 70 fixedly attached to an 05 elongated track tube 72 such as by welding. The track tube 72 is preferably cylindrical in shape and i5 disposed substantially parallel to the axis of the drum 14, as illustrated in Figure 1. The guiae support member 70 is disposed substantially perpendicular to the axis of the drum 14.
A pair of brackets 74 and 76 having bearings are fixedly mounted to a floor or frame. The tube 72 extends through the brackets 74 and 76 and engages the bearings, permitting the guide tube to slide in opposite transverse directions, along its axis as indicated by arrow 78, substantially parallel to the axis of the drum 1~.
The brackets 74 and 76 are spaced apart at least the distance of the end plates 38 and 40, as illustrated in Figure 2, permitting the guide support member to travel the entire distance between the end plates. The brackets 74 and 76 and track tube 72 provide sufEicient support during the winding operation to keep the guide support member 70 in a substantially perpendicular position to the axis of the drum 14.
A support bar 80 i8 positioned below the support guide member 70 proximate an end of the member 70 away from the drum 14. The support bar 80 is fixedly attached to the floor and supports the end of the guide member 70, as illustrated in Figure 3.
The right guiding mechanism further includes a hydraulic valve 82, a double-acting hydraulic actuator 84 and a cable contact-valve actuating member 86. The conduit 60 supplies hydraulic fluid under pressure to the hydraulic valve 82. The hydraulic valve 82 is a standard type of valve and is 05 fluidly connected to the actuator 84 on opposite sides of an internal piston by conduits 88 and 90.
The conduit 88 supplies hydraulic fluid to one side of the piston of actuator 84 and the conduit 90 supplies fluid to the other side of the piston of actuator 84. Hydraulic fluid is supplied under pressure either to line 88 or 90 and flows from the actuator 84 through either conduit 88 or 90, depending on the position of the valve.
The cable contact-valve actuating member 86 is slidably positioned on the support guide member 70 as indicated by arrow 96 and has a pair of upright contact rollers 92 and 94 between which the cable 22 rides. The rollers are spaced to fit closely against the cable so that any transverse movement of the cable will move the member 86. A connecting rod 98 connects the cable contact-valve actuating member 86 with an internal flow control spool of the valve 82.
The rod 98 is also movable in the direction of arrow 96 as controlled by lateral movement of the cable as it actuates the cable contact-valve actuating member 86 and places the valve in a state that either conveys hydraulic fluid under pressure in ei-ther conduit 90 or 88 and permits flow from the actuator 84 throuyh either conduit 90 or 88.
The hydraulic actuator 84 is a standard double-acting actuator having a cylinder housing 104 and a piston rod 105. The actuator 84 has a stroke length sufficiently long to move the guide support member 70 from one end plate 38 to the other end plate 40. The piston rod 105 is pivotally connected to a bracket 100 at one end that is secured to the floor. At the other end of the actuator 84, a 05 pivotal connector 102 pivotally connects an end of the housing 10~ to the guide support member 70. The pivotal connector 102 is a universal-type connector having an end 106 fixedly attached, such as by welding, to the guide support member 70 and another end 108 preferably being an integral part of the housing 104. A middle section 110 is attached to the end 106 by a pivot pin 112 and to the end 108 by a pivot pin 11~. A~ will be easily understood by those skilled in the art, actuator 84 is securely and flexibly attached to the guide support member 70.
~ cable guide 114 is securely attached on a top ~urface of the control guide member 70 proximate an end closest to the drum 14, as best illustrated in Figures 2 and 3. The guide 114 includes a pair of substantially upright roller~ 116 and 118 rotatably attached to the guide support member 70 at their bottom ends and rotatably attached to a connecting member 120 at their top ends. The rollers 116 and 118 are spaced apart sueficierltly to permit the cable to move in the transverse direction a limited distance between these guides while the cable is being wound. The connecting member 120 insures that th,e cable 22 stays between the rollers 116 and 118.
A second guide 122 is positioned on the guide support member 70 proximate the end farthest from the drum 14, as illustrated in Figures 2 and 3, and on the opposite side of cable control valve actuating member 86 from guide 114. Preferably, the ::~2~2~:~3 guide 122 includes a pair of substantially upright rollers 124 and 126 spaced f.rom each other a distance approximately equal to the diameter of the cable 22.
~ third substan-tially hori~ontal roller 128 is 05 positioned on a side of the upright rollers 124 and 126 that is closest to the drum 14. The substantially horizontal roller 128 is rotatably attached to a pair of substantially upright tab members 130 and 132 that are securely attached to the guide support mem~er 70, such a~ by welding.
Preferably, the substantially horizontal roller 128 is positioned above the uppermost end of the upright xollers 124 and 126, as illustrated in Figure 3.
The guides 114 and 122 define respective openings th.rough which the cable extends. The cable also extends through the cable contact-valve actuating member 86. The openings and the distance between the openings define a cable path along which the cable travels before being wound on the drum 14.
'rhe substantia:Lly upright rollers 124 and 126 o~ the guide 122 engage the cable 22 between each other on two sides and deEine a fixed point in the transverse direction along the cable path. ~s the cable is wound onto the drum 14, the cable positions itself adjacent to a previous wrap o~ cable on the drum and moves in a transverse direction between the rollers 116 and 118 oE the guide 114, while being held in a fixed transverse position by the guide 122. The rollers 116 and 118 are spaced so the cable length extending between guides 114 and 122 moves in a transverse direction suf~iciently to move the cable contact-valve actuating member 86. The member 86, through connecting rod 98, actuates the valve 82, 152~3 allowing hydraulic 1uid to enter the actuator 84 on one side of the internal piston and to exit on the other side of the piston. The actuator lengthens or shortens to move the guide support member 70 in the 05 proper transverse direction, guiding the cable onto the drum in even layers.
At the start of an operation, the cable 22 generally lies in a substantially perpendicular position to the axis of the drum 14. For purposes of an example, at the beginning of a winding operation, the cable is started near the end plate 38, as illustrated in ~igure 1. After the drum has completed a revolution and a length of the cable has been wound next to the end plate 38, the next length of cable to be wound will position itself next to the first length of cable. When the ne~t length of cable positions itself adjacent to the previous cable, the section of cable in the guide support member moves transversely to the right. The cable moves the cable contact-valve actuator member 86 to the right, actuating the valve 82 which allows hydraulic fluid t~ flow under pres~ure through conduit 90, and permits hydraulic fluid to flow out of the actuator 84 through conduit 88, moving the actuator i.n a ~5 direction of arrow 130 in a follow-up action until the valve 82 reaches a neutral position.
As the cable is wound further along the dr~um, successive winds of the cable will be positioned against each other and keep the member 86 positioned to the right, permitting more fluid to flow into the actuator through conduit 90 and more hydraulic fluid to escape through conduit 88, further moving the actuator in the direction of arrow 130.
~52~3 The actuator moves the support guide member 70 further to the right allowing the cable to wind substantially uniformly on the drum as a follow-up system that reaches a neutral position when the cable 05 contact-valve actuating member returns to a central position.
As should be understood from the above description, when the cable reaches the end plate 40, as shown in Figure 1, the next wind of cable will position itself on the drum to the left of the wind of cable next to the end plate 40. The cable contact-valve actuating member 86 is then moved by the cable to the left, reversing the flow of fluid into the hydraulic actuator. Reversing the flow of fluid moves the ac-tuator in a direction opposite to the arrow 130 thereby moving the guide support member 70 to the left permitting cable to be wound to the leEt on the drum 14 in a substantially even manner as the actuator Eollow~ up the cable movement.
The support guide member travels back and forth between the end plate 38 and 40 of the drum 14 in a similar manner to that described above until all the cable is wound onto the drum 14.
EIydraulic :Eluid under pressure is supplied by conduit 52 to both the left guiding mechanism and the right guiding mechanism, permitting both leEt and right guide mechanisms 42 and 44 to act independently of~each other. The cable is wound onto the drum 12 in a similar manner as was described with reEerence to the right guiding mechanism 44 and drum 14. It should be understood that the present invention is not limited to two drums being wound. A single drum or a number of drums may be wound using the present ~2~SZ~
invention. However, more than one drum is preferred since only one hydraulic system 46 is needed for a plurality of winding mechanisms, making the present invention desirable in terms of cost.
05 An alternative embodiment generally indicated at 150 is illustrated in Figures 4-7. The embodiment 150 includes a longitudinal tube 152, mounted to the floor (or a base 157 as illustrated only in Figure 6) by bracXets 154 and 156 proximate Eirst and second ends 158 and 160, and disposed substantially parallel to the axis of the drum.
A guide support member 162 is disposed sub~tantially perpendicularly to the axis of the drum, similarly to the guide support member 70, as discussed with reference to Figures 1-3. The guide support member includes a bearing sleeve 164 fixedly attached to a longitudinal supporting plate 166 that is disposed perpendicularly to the axis of the drum.
The bearing sleeve 164 slidably engages the circumference oE the tube 152 such that the guide support 162 easily slides along the length of the tube 152.
Similar to the embodiment discussed with reference to Figures 1-3, the embodiment 150 also includes a first cable guide 168 and a second cable guide 170, similar to the cable guides 114 and 122.
An actuating member 172, similar to the actuating me~ber 86 in Figures 1-3, i8 movable in a direction transverse to the winding of the cable such that any transverse movement of the cable will move the actuating member 172.
The actuating member 172 is connected to a hydraulic valve 174 connecting rod 176, as ~2~5~
illustrated in Figure 4. A hydraulic motor 178 is fluidly connected to the valve 174 by conduit 180 and 182 such that the motor 178 can be operated selectively in one direction and then another 05 depending on whether the flow of hydraulic fluid is -through conduit 180 or 182.
A double link-type chain 184 is attached to the tube 152 by a pair of slee~es 181 and 183 proximate ends 158 and 160, respectively. The sleeves 181 and 183 rotatably engage the tube 152 and have tab portions 185 and 187 that extend outwardly, spacing the chain 184 ~rom the tube 152. A
reinforcing tube 189 is disposed between and attached to the tab portions 185 and 187 between the chain 184 and the tube 152. Since the sleeves 181 and 183 are rotatable with respect to the tube 152, the chain 184 which is attached to the ends of the tab portions 185 and 187 is movable angularly with respect to the axis of the tube 152 along with guide support member 162.
The chain 184 extends preferably at least the width of the drum and i5 disposed substantially parall.el. to the axis o~ the drum. As best illustrated in E'igure 7, a sprocket 186 is drivably connected to the hydraulic motor 178 and has a plurality oE sprocket teeth 188 for engagement with the links oE the chain 1~4. First and second rollers 190 and 192 are rotatably attached to the bottom side of~ the guide support 162, as the sprocket 188 and the chain 184, and are positioned on opposite sides of the sprocket 186 to ensure that the sprocket teeth 188 engage the chain 184.
In operation, as a cable is being wound on the drum and guided by the cable guides 170 and 168 S~33 and moves transversely with respect to the direction of wind, the cable engages the actuator 172. The actuator 172 actuates the valve 174 and introduces flow of hydraulic fluid into the motor 178 through 05 either conduit 1~0 or 182. The motor 178 in turn turns the sprocket in a corresponding direction and the sprocket engages the chain moving the guide support member to position the cable so that successive winds of the cable will be positioned against each other on the drum.
A plurality of winding mechanisms illustrated in Figures 4 through 7 are provided for each corresponding drum, as discussed with reference to the embodiment in Figure 1, and provided with hydraulic fluid from one hydraulic system. With one hydraulic 9~S tem providing hydraulic fluid, the alternative embodiment is also desirable in terms of cost.
In summary, the present invention solves an ~0 old prohlem of winding steel cable substantially evenly on a drum in an economic and e~ficient manner~ The present invention permits multiple drums to be wound with cahle using only one hydraulic system.
Although the present invention has been described with reference to preferred embodiments, workers skilled in -the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.

The cables 20 and 22 are a braided, relatively large diameter, steel cable. In one successful application, the present invention is used to wind 5/8 inch diameter cable in a coal mine operation. The 5/8 inch cable is used to retrieve 4 , ' - ' .
,, ~2~5~3 inch diameter cable. It is important that the 5/8 inch cable is wound uniformly so that it is readily ava.ilable for subsequent operation.
The cable is wc~und onto the cdrums 12 and 14 05 in a substantially uniform manner by the cable guiding apparatus 24. ~he cable guiding apparatus 24 as illustrated in Figure 1, includes a left cable guiding mechanism 42 for guiding the cable 20 onto the drum 12 and a right cable guiding mechanism 44 for guiding the cable 22 onto the drum 14. Both the left and right cable guiding mechanisms 42, 44 receive power from a common hydraulic system 46. The hydraulic system 46 includes a reservoir 48, a hydraulic pump 50, a supply conduit 52 conveying hydraulic fluid to and a return conduit 54 conveying hydraulic fluid from the guiding apparatus 24, respectively.
Fluid is diverted to the left and right cable guidincJ mechanisms 42 and 44 through a flow divider 56. The Elow divider 56 diverts a portion of the hydraulic fluid to a conduit 58 to the leEt cable guiding mechanism 42 ancl to a conduit 60 to the right cable guidin~ mechanism 44. Hydraulic fluid flows back to the hydraulic system 46 through a conduit 62 from the left cable guiding mechanism 42 and through a conduit 64 from the. right cable guiding mechanism 44. The conduits 62 and 64 are joined by a Tee 66 which is connected to the return conduit 54~
The guiding mechanisms 42 and 44 are mirror images o~ each other and will be described with reference to right cable guiding mechanism 44 as illustrated in Figure 2. It is to be understood that like reference characters will indicate like elements ~4s;~r~53 of both left and right cable guiding mechanisms 42 and 44 as illustrated in Figure 1.
The right guiding mechanism 44 includes a guide support member 70 fixedly attached to an 05 elongated track tube 72 such as by welding. The track tube 72 is preferably cylindrical in shape and i5 disposed substantially parallel to the axis of the drum 14, as illustrated in Figure 1. The guiae support member 70 is disposed substantially perpendicular to the axis of the drum 14.
A pair of brackets 74 and 76 having bearings are fixedly mounted to a floor or frame. The tube 72 extends through the brackets 74 and 76 and engages the bearings, permitting the guide tube to slide in opposite transverse directions, along its axis as indicated by arrow 78, substantially parallel to the axis of the drum 1~.
The brackets 74 and 76 are spaced apart at least the distance of the end plates 38 and 40, as illustrated in Figure 2, permitting the guide support member to travel the entire distance between the end plates. The brackets 74 and 76 and track tube 72 provide sufEicient support during the winding operation to keep the guide support member 70 in a substantially perpendicular position to the axis of the drum 14.
A support bar 80 i8 positioned below the support guide member 70 proximate an end of the member 70 away from the drum 14. The support bar 80 is fixedly attached to the floor and supports the end of the guide member 70, as illustrated in Figure 3.
The right guiding mechanism further includes a hydraulic valve 82, a double-acting hydraulic actuator 84 and a cable contact-valve actuating member 86. The conduit 60 supplies hydraulic fluid under pressure to the hydraulic valve 82. The hydraulic valve 82 is a standard type of valve and is 05 fluidly connected to the actuator 84 on opposite sides of an internal piston by conduits 88 and 90.
The conduit 88 supplies hydraulic fluid to one side of the piston of actuator 84 and the conduit 90 supplies fluid to the other side of the piston of actuator 84. Hydraulic fluid is supplied under pressure either to line 88 or 90 and flows from the actuator 84 through either conduit 88 or 90, depending on the position of the valve.
The cable contact-valve actuating member 86 is slidably positioned on the support guide member 70 as indicated by arrow 96 and has a pair of upright contact rollers 92 and 94 between which the cable 22 rides. The rollers are spaced to fit closely against the cable so that any transverse movement of the cable will move the member 86. A connecting rod 98 connects the cable contact-valve actuating member 86 with an internal flow control spool of the valve 82.
The rod 98 is also movable in the direction of arrow 96 as controlled by lateral movement of the cable as it actuates the cable contact-valve actuating member 86 and places the valve in a state that either conveys hydraulic fluid under pressure in ei-ther conduit 90 or 88 and permits flow from the actuator 84 throuyh either conduit 90 or 88.
The hydraulic actuator 84 is a standard double-acting actuator having a cylinder housing 104 and a piston rod 105. The actuator 84 has a stroke length sufficiently long to move the guide support member 70 from one end plate 38 to the other end plate 40. The piston rod 105 is pivotally connected to a bracket 100 at one end that is secured to the floor. At the other end of the actuator 84, a 05 pivotal connector 102 pivotally connects an end of the housing 10~ to the guide support member 70. The pivotal connector 102 is a universal-type connector having an end 106 fixedly attached, such as by welding, to the guide support member 70 and another end 108 preferably being an integral part of the housing 104. A middle section 110 is attached to the end 106 by a pivot pin 112 and to the end 108 by a pivot pin 11~. A~ will be easily understood by those skilled in the art, actuator 84 is securely and flexibly attached to the guide support member 70.
~ cable guide 114 is securely attached on a top ~urface of the control guide member 70 proximate an end closest to the drum 14, as best illustrated in Figures 2 and 3. The guide 114 includes a pair of substantially upright roller~ 116 and 118 rotatably attached to the guide support member 70 at their bottom ends and rotatably attached to a connecting member 120 at their top ends. The rollers 116 and 118 are spaced apart sueficierltly to permit the cable to move in the transverse direction a limited distance between these guides while the cable is being wound. The connecting member 120 insures that th,e cable 22 stays between the rollers 116 and 118.
A second guide 122 is positioned on the guide support member 70 proximate the end farthest from the drum 14, as illustrated in Figures 2 and 3, and on the opposite side of cable control valve actuating member 86 from guide 114. Preferably, the ::~2~2~:~3 guide 122 includes a pair of substantially upright rollers 124 and 126 spaced f.rom each other a distance approximately equal to the diameter of the cable 22.
~ third substan-tially hori~ontal roller 128 is 05 positioned on a side of the upright rollers 124 and 126 that is closest to the drum 14. The substantially horizontal roller 128 is rotatably attached to a pair of substantially upright tab members 130 and 132 that are securely attached to the guide support mem~er 70, such a~ by welding.
Preferably, the substantially horizontal roller 128 is positioned above the uppermost end of the upright xollers 124 and 126, as illustrated in Figure 3.
The guides 114 and 122 define respective openings th.rough which the cable extends. The cable also extends through the cable contact-valve actuating member 86. The openings and the distance between the openings define a cable path along which the cable travels before being wound on the drum 14.
'rhe substantia:Lly upright rollers 124 and 126 o~ the guide 122 engage the cable 22 between each other on two sides and deEine a fixed point in the transverse direction along the cable path. ~s the cable is wound onto the drum 14, the cable positions itself adjacent to a previous wrap o~ cable on the drum and moves in a transverse direction between the rollers 116 and 118 oE the guide 114, while being held in a fixed transverse position by the guide 122. The rollers 116 and 118 are spaced so the cable length extending between guides 114 and 122 moves in a transverse direction suf~iciently to move the cable contact-valve actuating member 86. The member 86, through connecting rod 98, actuates the valve 82, 152~3 allowing hydraulic 1uid to enter the actuator 84 on one side of the internal piston and to exit on the other side of the piston. The actuator lengthens or shortens to move the guide support member 70 in the 05 proper transverse direction, guiding the cable onto the drum in even layers.
At the start of an operation, the cable 22 generally lies in a substantially perpendicular position to the axis of the drum 14. For purposes of an example, at the beginning of a winding operation, the cable is started near the end plate 38, as illustrated in ~igure 1. After the drum has completed a revolution and a length of the cable has been wound next to the end plate 38, the next length of cable to be wound will position itself next to the first length of cable. When the ne~t length of cable positions itself adjacent to the previous cable, the section of cable in the guide support member moves transversely to the right. The cable moves the cable contact-valve actuator member 86 to the right, actuating the valve 82 which allows hydraulic fluid t~ flow under pres~ure through conduit 90, and permits hydraulic fluid to flow out of the actuator 84 through conduit 88, moving the actuator i.n a ~5 direction of arrow 130 in a follow-up action until the valve 82 reaches a neutral position.
As the cable is wound further along the dr~um, successive winds of the cable will be positioned against each other and keep the member 86 positioned to the right, permitting more fluid to flow into the actuator through conduit 90 and more hydraulic fluid to escape through conduit 88, further moving the actuator in the direction of arrow 130.
~52~3 The actuator moves the support guide member 70 further to the right allowing the cable to wind substantially uniformly on the drum as a follow-up system that reaches a neutral position when the cable 05 contact-valve actuating member returns to a central position.
As should be understood from the above description, when the cable reaches the end plate 40, as shown in Figure 1, the next wind of cable will position itself on the drum to the left of the wind of cable next to the end plate 40. The cable contact-valve actuating member 86 is then moved by the cable to the left, reversing the flow of fluid into the hydraulic actuator. Reversing the flow of fluid moves the ac-tuator in a direction opposite to the arrow 130 thereby moving the guide support member 70 to the left permitting cable to be wound to the leEt on the drum 14 in a substantially even manner as the actuator Eollow~ up the cable movement.
The support guide member travels back and forth between the end plate 38 and 40 of the drum 14 in a similar manner to that described above until all the cable is wound onto the drum 14.
EIydraulic :Eluid under pressure is supplied by conduit 52 to both the left guiding mechanism and the right guiding mechanism, permitting both leEt and right guide mechanisms 42 and 44 to act independently of~each other. The cable is wound onto the drum 12 in a similar manner as was described with reEerence to the right guiding mechanism 44 and drum 14. It should be understood that the present invention is not limited to two drums being wound. A single drum or a number of drums may be wound using the present ~2~SZ~
invention. However, more than one drum is preferred since only one hydraulic system 46 is needed for a plurality of winding mechanisms, making the present invention desirable in terms of cost.
05 An alternative embodiment generally indicated at 150 is illustrated in Figures 4-7. The embodiment 150 includes a longitudinal tube 152, mounted to the floor (or a base 157 as illustrated only in Figure 6) by bracXets 154 and 156 proximate Eirst and second ends 158 and 160, and disposed substantially parallel to the axis of the drum.
A guide support member 162 is disposed sub~tantially perpendicularly to the axis of the drum, similarly to the guide support member 70, as discussed with reference to Figures 1-3. The guide support member includes a bearing sleeve 164 fixedly attached to a longitudinal supporting plate 166 that is disposed perpendicularly to the axis of the drum.
The bearing sleeve 164 slidably engages the circumference oE the tube 152 such that the guide support 162 easily slides along the length of the tube 152.
Similar to the embodiment discussed with reference to Figures 1-3, the embodiment 150 also includes a first cable guide 168 and a second cable guide 170, similar to the cable guides 114 and 122.
An actuating member 172, similar to the actuating me~ber 86 in Figures 1-3, i8 movable in a direction transverse to the winding of the cable such that any transverse movement of the cable will move the actuating member 172.
The actuating member 172 is connected to a hydraulic valve 174 connecting rod 176, as ~2~5~
illustrated in Figure 4. A hydraulic motor 178 is fluidly connected to the valve 174 by conduit 180 and 182 such that the motor 178 can be operated selectively in one direction and then another 05 depending on whether the flow of hydraulic fluid is -through conduit 180 or 182.
A double link-type chain 184 is attached to the tube 152 by a pair of slee~es 181 and 183 proximate ends 158 and 160, respectively. The sleeves 181 and 183 rotatably engage the tube 152 and have tab portions 185 and 187 that extend outwardly, spacing the chain 184 ~rom the tube 152. A
reinforcing tube 189 is disposed between and attached to the tab portions 185 and 187 between the chain 184 and the tube 152. Since the sleeves 181 and 183 are rotatable with respect to the tube 152, the chain 184 which is attached to the ends of the tab portions 185 and 187 is movable angularly with respect to the axis of the tube 152 along with guide support member 162.
The chain 184 extends preferably at least the width of the drum and i5 disposed substantially parall.el. to the axis o~ the drum. As best illustrated in E'igure 7, a sprocket 186 is drivably connected to the hydraulic motor 178 and has a plurality oE sprocket teeth 188 for engagement with the links oE the chain 1~4. First and second rollers 190 and 192 are rotatably attached to the bottom side of~ the guide support 162, as the sprocket 188 and the chain 184, and are positioned on opposite sides of the sprocket 186 to ensure that the sprocket teeth 188 engage the chain 184.
In operation, as a cable is being wound on the drum and guided by the cable guides 170 and 168 S~33 and moves transversely with respect to the direction of wind, the cable engages the actuator 172. The actuator 172 actuates the valve 174 and introduces flow of hydraulic fluid into the motor 178 through 05 either conduit 1~0 or 182. The motor 178 in turn turns the sprocket in a corresponding direction and the sprocket engages the chain moving the guide support member to position the cable so that successive winds of the cable will be positioned against each other on the drum.
A plurality of winding mechanisms illustrated in Figures 4 through 7 are provided for each corresponding drum, as discussed with reference to the embodiment in Figure 1, and provided with hydraulic fluid from one hydraulic system. With one hydraulic 9~S tem providing hydraulic fluid, the alternative embodiment is also desirable in terms of cost.
In summary, the present invention solves an ~0 old prohlem of winding steel cable substantially evenly on a drum in an economic and e~ficient manner~ The present invention permits multiple drums to be wound with cahle using only one hydraulic system.
Although the present invention has been described with reference to preferred embodiments, workers skilled in -the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
