Description

Technical Field

[0001] This invention relates to the field of cable processing technology, specifically to a secondary cable unwinding and straightening device. Background Technology

[0002] The construction of the secondary components of a substation is mainly divided into three parts: cable laying, cable treatment, and conductor connection. Cable treatment is further divided into three parts: cable stripping, cable unwinding, and conductor straightening. After stripping the cable to be connected, since the conductors inside the cable are spirally wound inside the cable's protective sheath, it is necessary to unwind and straighten each conductor before connecting it to the equipment terminals to facilitate the connection between the conductors and the equipment terminals.

[0003] Currently, in most substation secondary construction, the straightening and unwinding of cables is done manually by workers. Workers use electrician's pliers to clamp and fix the stripped cable cores, then pull and rotate the pliers to straighten the cores. Since each cable contains many cores, typically consisting of a grounding wire and multiple transmission lines, this process is time-consuming, leading to longer substation secondary construction times and requiring a large workforce for cable straightening and unwinding, thus increasing labor input. Therefore, this invention proposes a secondary cable straightening and unwinding device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a secondary cable unwinding and straightening device, which solves the problems of long time consumption and increased labor input in the secondary construction of substations for unwinding and straightening cable cores.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a secondary cable unwinding and straightening device, comprising a base, a bracket slidably connected to the upper side of the middle part of the base, a straightening and unwinding mechanism provided inside the lower side of the bracket, fixed frames fixedly connected to both sides of the left part of the bracket, a connecting frame fixedly connected between the two fixed frames, and a fixing mechanism provided on the right side of the connecting frame;

[0007] Preferably, a support base is fixedly connected to the right side of the base, and a fastening bolt is threaded inside the support base. A clamping plate is rotatably connected to the rear end of the fastening bolt.

[0008] Preferably, the lower outer periphery of the transmission gear meshes with the upper part of the rack, and the lower outer periphery of the worm gear meshes with the upper outer periphery of the worm.

[0009] Preferably, a sliding rod is fixedly connected to the rear side between the two fixed plates, and the inner rear side of the bracket is slidably connected to the outer periphery of the sliding rod.

[0010] Preferably, the fixing mechanism includes a locking tooth and a movable shaft. The locking tooth is fixedly connected to the inner top wall of the connecting frame. The left side of the outer periphery of the movable shaft is movably connected to the inside of the connecting frame. The right side of the outer periphery of the movable shaft is threadedly connected to the middle of the worm gear. A rotating block is rotatably connected to the right end of the movable shaft. Four connecting rods are hinged to the outer periphery of the rotating block. A clamping block is hinged to the end of the connecting rod away from the rotating block. A main gear is fixedly connected to the middle of the outer periphery of the movable shaft. Four slots are provided on both sides of the inside of the main gear. A secondary gear one and a secondary gear two are respectively provided on the left and right sides of the main gear. The middle of the secondary gear one and the secondary gear two are rotatably connected to the outer periphery of the movable shaft. Four convex grooves are provided on the side of the secondary gear one and the secondary gear two near the main gear. A locking block is slidably connected to one side of the convex groove. A limit block is fixedly connected to the middle of the locking block. The limit block is slidably connected to the inner side of the middle of the convex groove. A spring is provided on the other side of the convex groove.

[0011] Preferably, the lower part of the locking teeth is disposed on the upper side of the outer periphery of the first auxiliary gear, the second auxiliary gear, and the main gear.

[0012] Preferably, the clamping block is slidably connected inside the fixed base, and the side of the clamping block away from the movable shaft is disposed inside the through hole.

[0013] Preferably, the card blocks and card slots on the same side are adapted to each other, the left and right card blocks are vertically flipped together, and the left and right card slots are vertically flipped together.

[0014] Preferably, one end of the spring is fixedly connected to the inner wall of the convex groove, and the other end of the spring is fixedly connected to the middle of the limiting block.

[0015] Preferably, the right side of the first auxiliary gear and the left side of the second auxiliary gear are respectively engaged with the left and right sides of the main gear, and the main gear, the first auxiliary gear and the second auxiliary gear have the same number of teeth.

[0016] Working principle: The stripped cable cores are inserted into their corresponding through holes. When the number of cores exceeds the number of through holes, adjacent cores are inserted into a single through hole. The unstripped side of the cable is then placed in the notch of the support base. The fastening bolts are then tightened to secure one side of the cable via the clamps. The worker then starts the motor, which rotates the threaded rod, causing the support to move to the left. As the support moves to the left, the transmission gear drives the worm gear via the rack, which in turn drives the worm wheel. At this point, the secondary gear... The main gear is locked in place. Due to the limiting action of the locking teeth, as the worm gear rotates, the movable shaft is pushed towards the interior of the fixed seat. This causes the rotating block to push the clamping block towards the through hole via the connecting rod. The clamping block then holds and fixes the cable core inserted into the through hole. As the movable shaft continues to extend into the worm gear, the locking teeth sequentially engage with the outer circumference of the secondary gear, the main gear, and the primary gear. When the primary gear engages with the locking teeth, the direction of rotation at this point causes the primary gear to be unlocked from the main gear. In this state, the worm gear drives the movable shaft to rotate, preventing the worm gear from continuing to push the movable shaft. At this time, the cable core is clamped and fixed inside the through hole. As the fixing seat rotates and moves to the left, the cable core is quickly unspinned and straightened. After straightening and unspinning are completed, the motor stops working. Then, the worker loosens the fastening bolts and starts the motor in reverse to drive the straightening and unspinning mechanism to reset. At this time, the worm gear rotates in the opposite direction and drives the movable shaft to rotate. Since the first auxiliary gear and the main gear are locked at this time, while the second auxiliary gear and the main gear are unlocked, the worm gear rotates in the opposite direction. In this state, the worm gear will push the movable shaft outward, loosening the clamp and the wire core. At the same time, as the secondary gear one, main gear and secondary gear two reset and move, the clamping teeth will re-engage with secondary gear two. At this time, the rotation of the worm gear will drive the movable shaft to rotate, preventing the movable shaft from moving further. When the straightening and unspinning mechanism resets and moves a certain distance so that the fixing mechanism releases the wire core, the worker can pull the right side of the cable to pull out the cable, and then quickly and easily remove the unspinned and straightened cable. After the straightening and unspinning mechanism resets, the next cable unspinning and straightening work can be carried out.

[0017] This invention provides a secondary cable unwinding and straightening device. It has the following beneficial effects:

[0018] This invention, through the cooperation of a straightening and unspinning structure and a fixing mechanism, allows the fixed seat to simultaneously straighten the cable core horizontally and unspin it through the transmission of a bracket, worm gear, worm, gear, and rack, when the starting motor drives the threaded rod to rotate. Simultaneously, the rotation of the worm gear drives the movable shaft to move, and the engagement of the main gear and two auxiliary gears on the movable shaft enables rapid clamping and loosening of the cable core. This allows the cable unspinning and straightening device to conveniently and quickly perform unspinning and straightening operations on the cable core, thereby increasing the speed of cable processing, reducing the time required for secondary construction in substations, and lowering labor input.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] Example:

[0030] Please see the appendix Figure 1 -Appendix Figure 8 This invention provides a secondary cable unwinding and straightening device, including a base 1, a bracket 2 slidably connected to the upper side of the middle of the base 1, and the device performs unwinding and straightening operation on the cable core by moving the bracket 2. A straightening and unwinding mechanism 3 is provided inside the lower side of the bracket 2. Fixing frames 4 are fixedly connected to both sides of the left side of the bracket 2. A connecting frame 5 is fixedly connected between the two fixing frames 4. The connecting frame 5 supports the fixing mechanism 6, ensuring that the fixing mechanism 6 can clamp and fix the cable core when the device is running. The fixing mechanism 6 is provided on the right side of the connecting frame 5.

[0031] The straightening and unspinning mechanism 3 includes a fixed plate 301, a fixed block 305, a rack 308, and a fixed base 310. The lower parts of the two fixed plates 301 are fixedly connected to the upper left and right sides of the base 1, respectively. A motor 302 is fixedly connected to the left side of one of the fixed plates 301. A threaded rod 303 is rotatably connected between the two fixed plates 301 at the front. The left end of the threaded rod 303 is fixedly connected to the output end of the motor 302. The front of the bracket 2 is threadedly connected to the outer periphery of the threaded rod 303. When the worker starts the motor 302, it drives the threaded rod 303 to rotate, which in turn drives the bracket 2 to move to the left. The right sides of the two fixed blocks 305 are fixedly connected to the lower left side of the bracket 2. A rotating rod 306 is rotatably connected between the two fixed blocks 305. A worm gear 309 is fixedly connected to the middle of the outer periphery of the rotating rod 306. A transmission gear is fixedly connected to the front of the outer periphery of the rotating rod 306. Gear 307 and rack 308 are fixedly connected to the upper front side of base 1. As bracket 2 moves to the left, transmission gear 307 drives worm gear 309 to rotate through rack 308, which in turn drives worm wheel 311 to rotate. Worm wheel 311 drives fixed seat 310 to rotate. As fixed seat 310 rotates and moves to the left, it quickly unspins and straightens the cable core. The outer circumference of fixed seat 310 is rotatably connected to the inside of bracket 2. Worm wheel 311 is fixedly connected to the right side of fixed seat 310. Four through holes 312 are provided inside fixed seat 310. The through holes 312 are relatively long, so that after the cable core is inserted into the through hole 312, it moves in a circular motion and horizontally with the through hole 312, so that the fixing mechanism 6 has enough time to clamp and fix the cable core inserted into the through hole 312.

[0032] A support base 7 is fixedly connected to the right side of the base 1. A fastening bolt 8 is threaded inside the support base 7. A clamping plate 9 is rotatably connected to the rear end of the fastening bolt 8. The stripped cable cores are inserted into the corresponding through holes 312. When the number of cores is greater than the number of through holes 312, adjacent cores can be inserted into one through hole 312. Then, the unstripped side of the cable is placed in the notch of the support base 7. The fastening bolt 8 is then tightened to fix one side of the cable through the clamping plate 9. After that, the worker can start the device to straighten the cable cores.

[0033] The transmission gear 307 meshes with the lower outer periphery of the gear 307 and the upper part of the rack 308, and the worm gear 311 meshes with the lower outer periphery of the worm 309. This allows the threaded rod 303 to drive the bracket 2 to move on the upper part of the base 1, while simultaneously driving the fixed seat 310 to rotate and unwind the wire core, and simultaneously driving the fixed seat 310 to move horizontally and straighten the wire core.

[0034] A sliding rod 304 is fixedly connected to the rear side between the two fixed plates 301. The rear side of the bracket 2 is slidably connected to the outer periphery of the sliding rod 304. The sliding rod 304 can further limit the bracket 2, so that the bracket 2 can move horizontally stably. Thus, the cable core is straightened and unspinned by the cooperation of the straightening and unspinning mechanism 3 and the fixing mechanism 6.

[0035] The fixing mechanism 6 includes a locking tooth 601 and a movable shaft 602. The locking tooth 601 is fixedly connected to the inner top wall of the connecting frame 5. The left side of the outer periphery of the movable shaft 602 is movably connected to the inside of the connecting frame 5. The right side of the outer periphery of the movable shaft 602 is threadedly connected to the middle of the worm gear 311. A rotating block 603 is rotatably connected to the right end of the movable shaft 602. Four connecting rods 605 are hinged to the outer periphery of the rotating block 603. A clamping block 604 is hinged to the end of the connecting rod 605 away from the rotating block 603. A main gear 606 is fixedly connected to the middle of the outer periphery of the movable shaft 602. Four slots 607 are provided on both sides inside the main gear 606. As the bracket 2 moves to the left, the transmission gear 307 drives the worm gear 309 to rotate through the rack 308, thereby driving the worm gear 311 to rotate through the worm gear 309. When the worm gear 311 rotates, the secondary gear 609 and the main gear 606 are locked together. Due to the limiting action of the retaining teeth 601, the movable shaft 602 is pushed towards the interior of the fixed base 310 by the rotating worm gear 311. This causes the rotating block 603 to push the clamping block 604 towards the through hole 312 via the connecting rod 605. The clamping block 604 then clamps and fixes the cable core inserted into the through hole 312. As the movable shaft 602 continues to extend into the worm gear 311, the retaining teeth 601 sequentially engage with the outer circumference of the secondary gear 609, the main gear 606, and the primary gear 608. When the primary gear 608 moves and engages with the retaining teeth 601, the direction of rotation at this time causes the primary gear 608 and the main gear 606 to... When the worm gear 311 is in the unlocked state, it will drive the movable shaft 602 to rotate, preventing the worm gear 311 from continuing to push the movable shaft 602. At this time, the cable core will be clamped and fixed inside the through hole 312. The main gear 606 is provided with a secondary gear 1 608 and a secondary gear 2 609 on its left and right sides, respectively. The middle of the secondary gear 1 608 and the secondary gear 2 609 are rotatably connected to the outer periphery of the movable shaft 602. The inner side of the secondary gear 1 608 and the secondary gear 2 609 near the main gear 606 is provided with four convex grooves 610. A locking block 612 is slidably connected to one side of the convex groove 610. A limit block 611 is fixedly connected to the middle of the locking block 612. The limit block 611 is slidably connected to the inner side of the middle of the convex groove 610. A spring 6 is provided on the other side of the convex groove 610. 13. As the fixed base 310 rotates and moves to the left, it quickly unspins and straightens the cable core. After straightening and unspinning are completed, the motor 302 stops working. Then, the worker loosens the fastening bolt 8 and starts the motor 302 in reverse to drive the straightening and unspinning mechanism 3 to reset. At this time, the worm gear 311 rotates in the reverse direction and drives the movable shaft 602 to rotate. Since the auxiliary gear 608 and the main gear 606 are locked at this time, while the auxiliary gear 609 and the main gear 606 are unlocked, the worm gear 311 will push the movable shaft 602 outward, loosening the clamp 604 and the cable core. At the same time, as the auxiliary gear 608, the main gear 606 and the auxiliary gear 609 reset and move, the locking tooth 601 will re-engage with the auxiliary gear 609.At this time, the rotation of the worm gear 311 will drive the rotation of the movable shaft 602, preventing the movable shaft 602 from continuing to move. This ensures that after the fixing mechanism 6 loosens the wire core, the movable shaft 602 will not continue to move horizontally, but will change from horizontal movement to rotational motion. This prevents the worm gear 311 and the movable shaft 602 from being constantly strained and breaking. After the straightening and unwinding mechanism 3 resets, causing the fixing mechanism 6 to loosen, the worker can remove the unwound wire core. The slight misalignment of the wire core caused by the reset movement of the straightening and unwinding mechanism 3 will cause the worker to pull the wire core away from the fixing seat 310. The wire core will then be pulled out through the notch in the middle of the support seat 7, and the wire core can be straightened through the notch inside the support seat 7.

[0036] The lower part of the retaining gear 601 is located on the upper outer periphery of the secondary gear 608, secondary gear 609, and main gear 606. The retaining gear 601 limits the movement of the main gear 606, preventing the movable shaft 602 from rotating during movement. This allows the movable shaft 602 to push the clamping block 604 to hold and fix the wire core. Simultaneously, the cooperation of the secondary gears 608 and 609 prevents the movable shaft 602 from continuing to move horizontally due to the worm gear 311 after clamping or releasing, thus preventing the worm gear 311 from driving the movable shaft 602 to rotate. This also prevents the threads between the worm gear 311 and the movable shaft 602 from breaking.

[0037] The clamping block 604 is slidably connected inside the fixed base 310. The side of the clamping block 604 away from the movable shaft 602 is set inside the through hole 312. Through the synchronous movement of multiple clamping blocks 604, the wire core inside the through hole 312 is quickly clamped and fixed, which facilitates the device to unspin and straighten the cable core.

[0038] The locking block 612 and the locking slot 607 on the same side are compatible, and the cross-sectional area of ​​the locking slot 607 is larger than that of the locking block 612, allowing the locking block 612 to disengage after being inserted into the locking slot 607. Through the cooperation of the ramp and step on one side of the locking block 612 and the locking slot 607, when one of the two secondary gears is locked, the other secondary gear is unlocked. The locking state of the two secondary gears can be automatically switched according to the direction of rotation of the movable shaft 602, thereby enabling the secondary gear 608 to... The sliding switching between the main gear 606 and the secondary gear 609 and the clamping tooth 601 enables the device to clamp and fix the wire core, and avoids excessive movement of the movable shaft 602, which could cause the thread between the movable shaft 602 and the worm gear 311 to break. The left and right clamping blocks 612 are vertically flipped, and the left and right clamping slots 607 are vertically flipped. As the movable shaft 602 rotates clockwise or counterclockwise, the secondary gear 608 and the secondary gear 609 will be locked or unlocked in sequence with the clamping tooth 601.

[0039] One end of the spring 613 is fixedly connected to the inner wall of the convex groove 610, and the other end of the spring 613 is fixedly connected to the middle of the limiting block 611. The limiting block 611 is held in place by the spring 613, so that the spring 613 will tightly hold the locking block 612 against the inside of the locking groove 607. When the locking block 612 and the locking groove 607 move relative to each other along the direction of the slope, the locking block 612 and the locking groove 607 cannot be stably engaged, so that the corresponding secondary gear and the main gear 606 will rotate relative to each other. When the locking block 612 and the locking groove 607 move relative to each other along the direction of the step, the corresponding secondary gear and the main gear 606 will be relatively stationary. Thus, the locking teeth 601 limit the movement of the movable shaft 602 and prevent the movement of the movable shaft 602 from rotating.

[0040] The right side of auxiliary gear 1 608 and the left side of auxiliary gear 2 609 respectively engage with the left and right sides of main gear 606. Main gear 606, auxiliary gear 1 608, and auxiliary gear 2 609 have the same number of teeth, allowing the two auxiliary gears and main gear 606 to smoothly switch with the locking teeth 601 during movement. When one of the auxiliary gears and main gear 606 is in the locked state, the teeth of the two auxiliary gears and main gear 606 are aligned. At the same time, the friction between the two auxiliary gears and the outer circumference of the movable shaft 602 is large, and the device operates at a slow speed. This ensures that when one auxiliary gear is in the unlocked state, it can cooperate with the ramp between the locking groove 607 and the locking block 612, ensuring that the unlocked auxiliary gear will not rotate relative to the movable shaft 602.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
