Description

Technical Field

[0001] The present invention belongs to the technical field of cable processing, and specifically relates to a cable straightening process and a wire releasing and pulling device therefor. Background Art

[0002] A cable is a line device for power or signal transmission, usually composed of one or several wires. Each group of wires inside the cable will be wrapped with an insulating protective layer on the outside to achieve the effect of mutual insulation between each group of wires. At the same time, a highly insulating covering layer will be wrapped on the outside of the entire cable. Therefore, the cable has the characteristics of conducting electricity inside and being insulated outside.

[0003] When storing a cable, to make the cable convenient for transportation, save space, and also to protect the cable, the cable is usually wound around a winding roller. At the same time, when storing the winding roller wound with the cable, it needs to be placed in a position where it is avoided from water sources and not in contact with acids, alkalis, or mineral oils, and it also needs to be noted that it cannot be directly exposed to sunlight or an ultra-high temperature environment.

[0004] During the long-term winding and storage of the cable, since there are metal wires inside the cable, after the cable is wound, the cable will undergo bending deformation. During the use of the cable, to ensure the normal use of the cable, the cable needs to be straightened. However, the existing straightening devices are difficult to adjust according to the diameter of the cable, especially the diameter of large-diameter cables, resulting in a large processing limitation of the straightening device.

Detailed implementation manners

[0037] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0038] As Figure 1 shown, a cable straightening process according to an embodiment of the present invention has the following specific steps:

[0039] S1: Control the servo motor to drive the threaded rod 12 to rotate, so that the sliding block 10 slides downward, and then roll the winding roller wound with the cable to the position corresponding to the wire-releasing rod 9;

[0040] S2: Start the electric push rod, so that the electric push rod pushes the wire-releasing rod 9 to slide into the slot inside the opposite sliding block 10, and then passes through the cavity in the middle of the winding roller and finally inserts into the inside of the slot;

[0041] S3: Rotate the rotating handle 20, so that the rotating handle 20 drives the second rotating shaft 18 and the pushing block 19 to rotate, and then the pushing block 19 pushes the pushed plate 171, so that the deflecting plate 17 deflects to squeeze and fix the cavity of the winding roller. After the adjustment is completed, rotate the rotating handle 20 so that the rotating handle 20 is squeezed against the end side wall of the wire-releasing rod 9 to fix the rotating handle 20 and the second rotating shaft 18, and then use the fixing bolt 14 to fix the anti-detachment plate 13 to the end of the wire-releasing rod 9;

[0042] S4: Rotate the pushing bolt 25, so that the pushing bolt 25 pushes the friction block 24 to descend to adjust the extrusion force between the friction block 24 and the anti-detachment plate 13;

[0043] S5: Control the servo motor to drive the threaded rod 12 to rotate, raise the sliding block 10, then introduce one end of the cable on the winding roller between the first pulling wheel 5 and the second pulling wheel 501, and control the electric push cylinder to adjust the heights of the pushing plate 7 and the fixed seat 8, so that the first pulling wheel 5 on the fixed frame 2 and the second pulling wheel 501 installed inside the fixed seat 8 squeeze the cable, and drive the first pulling wheel 5 and the second pulling wheel 501 to rotate through the driving motor to straighten the cable by pulling.

[0044] As Figures 2 to 3 shown, a cable pay-off and pulling device, which is applicable to the above-mentioned cable straightening process, includes a pulling base 1; two symmetrically arranged fixed frames 2 are fixedly connected to the top of the pulling base 1; a plurality of first rotating shafts 3 are rotatably connected inside the fixed frame 2; anti-detachment blocks 4 are fixedly connected to both ends of the first rotating shaft 3; a first pulling wheel 5 is fixedly connected to the first rotating shaft 3; synchronous wheels are installed on the first rotating shaft 3, and the plurality of synchronous wheels are connected by a synchronous belt 6; a pushing plate 7 is slidably connected inside the pulling base 1, and the sliding of the pushing plate 7 is driven by an electric push cylinder; a fixed seat 8 is fixedly connected to the top of the pushing plate 7; the fixed seat 8 is arranged at a position corresponding to the bottom of the first rotating shaft 3; a second pulling wheel 501 is rotatably connected inside the fixed seat 8; a roller placing assembly is arranged on the top of the pulling base 1, and the roller placing assembly can support the winding roller of the cable; the rotations of the first pulling wheel 5 and the second pulling wheel 501 are both driven by a driving motor; during operation, when the cable needs to be straightened and pulled, the winding roller wound with the cable needs to be supported by the roller placing assembly to separate the winding roller from the ground, then lead out one end of the cable, and pass it through between the first pulling wheel 5 installed on the first rotating shaft 3 and the second pulling wheel 501 installed inside the fixed seat 8, then the pushing plate 7 can be pushed by the electric push cylinder to make the pushing plate 7 rise, and the cable is squeezed by the first pulling wheel 5 and the second pulling wheel 501, then the driving motor can be started to drive the first pulling wheel 5 and the second pulling wheel 501 to rotate, and then the cable is pulled by the rotation of the first pulling wheel 5 and the second pulling wheel 501, and the cable is straightened by pulling, so that the cable straightening work can be more convenient. At the same time, by pushing the pushing plate 7 by the electric push cylinder to adjust the height of the second pulling wheel 501 installed inside the fixed seat 8, the device can better adapt to cables of various diameters.

[0045] As Figures 2 to 6As shown in the figure, the unwinding roller assembly includes a pair of sliding frames 201; the pair of sliding frames 201 are symmetrically arranged on the top of the pulling base 1; a sliding block 10 is slidably connected inside the sliding frame 201; an anti-deviation groove 102 is formed inside the sliding frame 201; an anti-deviation block 101 is fixedly connected to the outer side wall of the sliding block 10; the anti-deviation block 101 and the anti-deviation groove 102 are correspondingly arranged; an electric push rod is fixedly connected to the side wall of one of the sliding blocks 10, and a wire unwinding rod 9 and a pushing rod 15 are arranged at the output end of the electric push rod; the electric push rod is arranged on the side wall of the sliding block 10 away from the other sliding block 10; a slot is formed inside the sliding block 10 without the electric push rod, and the slot is arranged at the position corresponding to the wire unwinding rod 9; a fixing plate 11 is fixedly connected inside the pulling base 1; a servo motor is installed at the bottom of the fixing plate 11; a threaded rod 12 is fixedly connected to the output end of the servo motor; the threaded rod 12 is threadedly connected inside the sliding block 10; during operation, when it is necessary to place the winding roller, the electric push rod can be controlled to drive the wire unwinding rod 9 and the pushing rod 15 to slide, so that the wire unwinding rod 9 and the pushing rod 15 retract into the electric push rod. Then, the servo motors on both sides can be controlled to drive the threaded rod 12 to rotate, so that the two sliding blocks 10 stay inside the cavity in the middle of the winding roller. During the process of driving the servo motor, the winding roller can be rolled between the two sliding frames 201, and the cavity stays at the position corresponding to the wire unwinding rod 9 and the pushing rod 15. Then, the electric push rod can be controlled to push the wire unwinding rod 9 and the pushing rod 15 to slide towards the slot position of the other sliding block 10, so that the wire unwinding rod 9 and the pushing rod 15 are inserted into the slot inside the opposite sliding block 10, thereby supporting the winding roller. Then, the servo motor can be controlled to drive the threaded rod 12 to rotate, lifting the wire unwinding rod 9 and the pushing rod 15 upwards, and then driving the winding roller to rise upwards, so that the winding roller is separated from the ground. When pulling the cable on the winding roller, it effectively avoids the situation that the winding roller rolls and affects the pulling work. By restricting the anti-deviation block 101 through the anti-deviation groove 102, the sliding block 10 can better maintain stability when rising or falling.

[0046] As Figure 7 shown, an anti-detachment plate 13 is fixedly connected to the end of the wire unwinding rod 9 through a fixing bolt 14; the anti-detachment plate 13 is arranged at the end of the wire unwinding rod 9, and at the same time, the anti-detachment plate 13 contacts the side wall of the sliding block 10 away from the electric push rod; during operation, after the wire unwinding rod 9 passes through the slot formed inside the sliding block 10, the anti-detachment plate 13 is fixed to the end of the wire unwinding rod 9 through the fixing bolt 14. When the wire unwinding rod 9 supports the winding roller, it can block the wire unwinding rod 9, assist the wire unwinding rod 9 to support the winding roller, and conduct the pressure received by the wire unwinding rod 9 to the side wall of the sliding block 10 in contact with the anti-detachment plate 13, so that the effect of the winding roller supporting the wire unwinding rod 9 is better.

[0047] As shown Figures 5 to 8 in the figure, a rotating block 16 is fixedly connected to the end of the wire releasing rod 9 close to the side of the electric push rod; the rotating block 16 is rotatably connected inside the push rod 15; the push rod 15 is arranged on the side close to the electric push rod, and the wire releasing rod 9 is arranged on the side of the push rod 15 away from the electric push rod; a deflecting plate 17 is rotatably connected to the inside of the wire releasing rod 9 through a torsion spring; a pushed plate 171 is fixedly connected to the side wall of the deflecting plate 17; the pushed plate 171 is arranged at the position inside the wire releasing rod 9; a second rotating shaft 18 is rotatably connected to the inside of the wire releasing rod 9; a pushing block 19 is fixedly connected to the outer side wall of the second rotating shaft 18; the pushing block 19 is arranged at the position corresponding to the pushed plate 171; a rotating handle 20 is fixedly connected to the end of the second rotating shaft 18; the rotating handle 20 is arranged at the end of the second rotating shaft 18 close to the anti - detachment plate 13; an anti - rotation bolt 21 is threadedly connected to the inside of the rotating handle 20; the anti - rotation bolt 21 is arranged at the position corresponding to the side wall of the sliding block 10; a sliding seat 23 is fixedly connected to the outer side wall of the sliding block 10; the sliding seat 23 is arranged at the position corresponding to the top of the anti - detachment plate 13; a friction block 24 is slidably connected to the inside of the sliding seat 23; a pushing bolt 25 is threadedly connected to the inside of the sliding seat 23; the pushing bolt 25 is rotatably connected to the inside of the friction block 24; during operation, when the wire releasing rod 9 is used to fix the winding roller, the rotating handle 20 can be rotated, so that the rotating handle 20 drives the second rotating shaft 18 to rotate, and then the second rotating shaft 18 drives the pushing block 19 to push the pushed plate 171, so that the deflecting plate 17 deflects towards the side close to the winding roller and is mutually extruded with the inside of the winding roller. Then, the anti - rotation bolt 21 is rotated so that the anti - rotation bolt 21 is extruded against the side wall of the wire releasing rod 9 to lock and fix the rotating handle 20 and the second rotating shaft 18, so that the winding roller can rotate synchronously with the wire releasing rod 9. When the cable is pulled, by the synchronous rotation of the wire releasing rod 9 and the winding roller, the wear between the winding roller and the wire releasing rod 9 can be effectively reduced. At the same time, the pushing bolt 25 can be rotated so that the pushing bolt 25 pushes the friction block 24 to slide downwards and is mutually extruded with the anti - detachment plate 13, and the friction force between the friction block 24 and the anti - detachment plate 13 can be controlled, so that the pulling force during pulling can be controlled, making the straightening process of the cable during pulling more convenient.

[0048] As shown Figures 2 to 4 in the figure, a positioning rod 26 is fixedly connected to the top of the fixing plate 11; a positioning hole is formed inside the sliding block 10, and the positioning hole corresponds to the position of the positioning rod 26; during operation, when the threaded rod 12 rotates to drive the sliding block 10 to slide up or down, due to the restriction of the positioning rod 26 on the positioning hole, the sliding block 10 is less likely to tilt during the sliding process, making the sliding of the sliding block 10 more stable.

[0049] As Figure 10 shown, a sliding plate 27 is slidably connected inside the fixing bolt 14; a connecting rod 28 is fixedly connected to the bottom of the sliding plate 27; a contact block 29 is fixedly connected to the bottom end of the connecting rod 28; a spring is fixedly connected between the top of the sliding plate 27 and the inner side wall of the fixing bolt 14; during operation, when the anti-detachment plate 13 is fixed by the fixing bolt 14, during the process of screwing the fixing bolt 14 into the threaded hole, the contact block 29 will first contact the bottom of the threaded hole, and then when the fixing bolt 14 is further screwed in, the contact block 29 is blocked and can push the sliding plate 27 through the connecting rod 28, and then the sliding plate 27 is pushed to compress the spring. By the elastic force of the spring pushing the sliding plate 27, the friction between the threads on the surface of the fixing bolt 14 and the threads of the fixing bolt 14 can be made larger, so that the fixing effect of the fixing bolt 14 on the anti-detachment plate 13 is better.

[0050] As Figure 9 shown, a rotating seat plate 30 is fixedly connected to the side wall of the sliding frame 201; a positioning block 31 is fixedly connected to the end of the threaded rod 12; the positioning block 31 is rotatably connected inside the rotating seat plate 30; during operation, when the threaded rod 12 rotates, due to the restriction of the rotating seat plate 30 on the positioning block 31, the threaded rod 12 is less likely to tilt during rotation, making the rotation of the threaded rod 12 more stable.

[0051] As Figure 9 shown, a plurality of balls 32 are provided between the rotating seat plate 30 and the positioning block 31; the balls 32 are in contact with the side walls of both the rotating seat plate 30 and the positioning block 31; during operation, when the positioning block 31 rotates inside the rotating seat plate 30, through the rolling of the balls 32, the sliding friction between the rotating seat plate 30 and the positioning block 31 can be changed into rolling friction, making the friction between the rotating seat plate 30 and the positioning block 31 smaller, and thus reducing the wear between the rotating seat plate 30 and the positioning block 31.

[0052] As Figure 7 shown, a rubber pad 33 is fixedly connected to the end of the wire-releasing rod 9; the rubber pad 33 is arranged at the position corresponding to the end of the anti-rotation bolt 21; during operation, when the rotation handle 20 is locked and fixed by the anti-rotation bolt 21, by providing the rubber pad 33 at the end of the wire-releasing rod 9, the contact area between the anti-rotation bolt 21 and the end of the wire-releasing rod 9 can be made larger, so that the friction between the anti-rotation bolt 21 and the wire-releasing rod 9 is larger, making the locking and fixing effect of the anti-rotation bolt 21 on the rotation handle 20 better.

[0053] During operation, when the cable needs to be straightened and pulled, the winding roller wrapped with the cable needs to be supported by the roller assembly so that the winding roller is separated from the ground, and then one end of the cable is led out and passed between the first pulling wheel 5 installed on the first rotating shaft 3 and the second pulling wheel 501 installed inside the fixed seat 8, and then the pushing plate 7 can be pushed by the electric pushing cylinder to make the pushing plate 7 rise, and the cable is squeezed by the first pulling wheel 5 and the second pulling wheel 501, and then the driving motor can be started so that the driving motor drives the first pulling wheel 5 and the second pulling wheel 501 to rotate, and then the first pulling wheel 5 and the second pulling wheel 501 rotate to pull the cable, and the cable is straightened by pulling, so that the cable straightening work can be more convenient, and at the same time, the pushing plate 7 is pushed by the electric pushing cylinder to adjust the height of the second pulling wheel 501 installed inside the fixed seat 8, so that the device can better adapt to cables of various diameters.

[0054] When the winding roller needs to be placed, the electric push rod can be controlled to drive the wire-releasing rod 9 and the pushing rod 15 to slide, so that the wire-releasing rod 9 and the pushing rod 15 are retracted into the interior of the electric push rod, and then the servo motors on both sides can be controlled to make the servo motors drive the threaded rod 12 to rotate, so that the two sliding blocks 10 stay inside the cavity in the middle of the winding roller. In the process of driving the servo motor, the winding roller can be rolled between the two sliding frames 201, and the cavity can stay at the position corresponding to the wire-releasing rod 9 and the pushing rod 15, and then the electric push rod can be controlled to push the wire-releasing rod 9 and the pushing rod 15 to the slot position of the other sliding block 10. The wire-releasing rod 9 and the pushing rod 15 are inserted into the slots inside the opposite sliding block 10, thereby supporting the winding roller. The servo motor can then be controlled to drive the threaded rod 12 to rotate, thereby raising the wire-releasing rod 9 and the pushing rod 15, thereby driving the winding roller to rise, so that the winding roller is separated from the ground. When the cable on the winding roller is pulled, the winding roller is effectively prevented from rolling, which affects the pulling work. The anti-deflection block 101 is restricted by the anti-deflection groove 102, so that the sliding block 10 can be better kept stable when rising or falling.

[0055] When the pay-off rod 9 passes through the slot opened inside the sliding block 10, the anti-slip plate 13 is fixed to the end of the pay-off rod 9 by the fixing bolt 14, so that when the pay-off rod 9 supports the winding roller, the pay-off rod 9 can be blocked, which can assist the pay-off rod 9 in supporting the winding roller and transmit the pressure on the pay-off rod 9 to the side wall of the sliding block 10 in contact with the anti-slip plate 13, so that the winding roller can better support the pay-off rod 9.

[0056] When fixing the winding roller through the wire guiding rod 9, the rotating handle 20 can be rotated, so that the rotating handle 20 drives the second rotating shaft 18 to rotate. Further, the second rotating shaft 18 drives the pushing block 19 to push the pushed plate 171, so that the deflecting plate 17 deflects towards the side close to the winding roller and is mutually extruded with the inside of the winding roller. Then, the anti-rotation bolt 21 is rotated so that the anti-rotation bolt 21 is extruded against the side wall of the wire guiding rod 9 to lock and fix the rotating handle 20 and the second rotating shaft 18, enabling the winding roller to rotate synchronously with the wire guiding rod 9. When pulling the cable, the synchronous rotation of the wire guiding rod 9 and the winding roller can effectively reduce the wear between the winding roller and the wire guiding rod 9. At the same time, the pushing bolt 25 can be rotated so that the pushing bolt 25 pushes the friction block 24 to slide downward and is mutually extruded with the anti-disengagement plate 13, enabling the control of the friction force between the friction block 24 and the anti-disengagement plate 13, thereby controlling the pulling force during traction and making the straightening process of the cable more convenient.

[0057] When the threaded rod 12 rotates to drive the sliding block 10 to slide upward or downward, through the restriction of the positioning rod 26 on the positioning hole, the sliding block 10 can be less inclined during the sliding process, making the sliding of the sliding block 10 more stable.

[0058] When fixing the anti-disengagement plate 13 through the fixing bolt 14, during the process of screwing the fixing bolt 14 into the threaded hole, the contact block 29 will first contact the bottom of the threaded hole. Then, after continuing to screw in the fixing bolt 14, the contact block 29 is blocked and can push the sliding plate 27 through the connecting rod 28. Further, the sliding plate 27 pushes the spring, and the sliding plate 27 is pushed by the elastic force of the spring, enabling the friction force between the thread on the surface of the fixing bolt 14 and the thread of the fixing bolt 14 to be greater, making the fixing effect of the fixing bolt 14 on the anti-disengagement plate 13 better.

[0059] When the threaded rod 12 is rotating, through the restriction of the rotating seat plate 30 on the positioning block 31, the threaded rod 12 can be less inclined during the rotation process, making the rotation of the threaded rod 12 more stable.

[0060] When the positioning block 31 rotates inside the rotating seat plate 30, through the rolling of the balls 32, the sliding friction between the rotating seat plate 30 and the positioning block 31 can be changed into rolling friction, making the friction force between the rotating seat plate 30 and the positioning block 31 smaller, and thus reducing the wear between the rotating seat plate 30 and the positioning block 31.

[0061] When locking and fixing the rotating handle 20 through the anti-rotation bolt 21, by providing a rubber pad 33 at the end of the wire pay-off rod 9, the contact area between the anti-rotation bolt 21 and the end of the wire pay-off rod 9 can be made larger, so that the frictional force between the anti-rotation bolt 21 and the wire pay-off rod 9 can be made larger, and the locking and fixing effect of the anti-rotation bolt 21 on the rotating handle 20 can be better.
