A winding device for power detection

Abstract

The present invention relates to the field of cable winding, and specifically to a winding device for electric power detection, including a fixing frame, a winding wheel, a detection component and a tightening component. One end of the cable is fixed in a locking hole, and the winding wheel is driven to rotate by a power source. When the cable is wound on the winding wheel, the cable gradually advances along a first axial direction, and one end of the tightening rod abuts against a side wall of the cable in the forward direction of the first axial direction, and the other end of the tightening rod is arranged on a slider. Under the pushing force of the cable, the slider slides synchronously along the first axial direction on the fixing frame, and the slider has a constant resistance when sliding on the first axis of the fixing frame, so that the cable is tightly arranged when a single layer is wound on the winding wheel. When the cable is wound to the end of the winding wheel, the adjustment unit adjusts the tightening rod to slide a fixed distance along the first slideway, so that after the cable is wound in a layer-changing manner, the tightening rod still abuts against the side wall of the cable in the forward direction of the first axial direction, so that the cable is always tightly arranged on the winding roller.

Description

Technical Field

[0001] The present invention relates to the field of cable winding, and in particular to a winding device for power detection. Background Art

[0002] In order to facilitate the transportation and sale of completed cables, the cables need to be wound onto a winding wheel so that the cables are wound into independent coils. When winding cables of the same length, the tightness of the cable winding determines the size of the coil and the neatness of the coil. Tightly wound cables reduce the probability of the cables becoming loose during transportation. During the cable processing and production process, in order to ensure the insulation of the cables, an insulating jacket is added to the outside of the conductors, and the flame retardancy of the insulating jacket must be ensured to improve the safety of the cables during use. Existing cables often use low-smoke halogen-free wire sheaths, which are made of thermoplastic or thermosetting plastics that have low smoke emissions when heated and do not contain halogens. After adding a low-smoke halogen-free protective jacket to the outside of the conductors, qualified cables are formed.

[0003] A winding device is required when winding the cable, but the existing cable winding device cannot provide stable resistance when winding the cable, resulting in the cable being wound loose, making it inconvenient to wind the cable neatly on the winding reel, and when continuing to wind the cable, it will be sandwiched between the next layer of loose cables, eventually leading to dislocation, etc., resulting in cable entanglement during the subsequent pay-off process, and the loose wire coil is prone to become loose during transportation.

[0027] An embodiment of a winding device for power detection of the present invention is as follows Figures 1 to 7 As shown, it includes a fixing frame, a winding wheel 120, a detection component and a tightening component.

[0028] The fixing frame includes a base plate 111 and a support plate 112. The base plate 111 is arranged horizontally. The support plate 112 is fixed by a connecting rod and is arranged parallel to the base plate 111. Three groups of brackets are fixed on the base plate 111. The three groups of brackets are divided into a first bracket 113, a second bracket 114 and a third bracket 115 from left to right, and the third bracket 115 is provided with a mounting groove 116 opening upward.

[0029] The reel 120 has a first axis, which is arranged horizontally. The reel 120 extends forward and backward. Limit plates 130 are fixedly provided at both the front and rear ends of the reel 120. The limit plates 130 are arranged coaxially with the reel 120. The diameter of the limit plates 130 limits the maximum diameter of the cable that can be wound on the reel 120. The end of the peripheral side wall of the reel 120 is provided with a locking hole opening outward. When reeling the cable, one end of the cable is first inserted into the locking hole. The rotating shaft of the reel 120 is rotatably arranged in the mounting slot 116 of the third bracket 115, so that the cable can be easily removed after being wound on the reel 120. A first transmission wheel 140 is fixedly provided on the rotating shaft of the reel 120. A support plate 160 is fixedly provided on the front side wall of the third bracket 115. The support plate 160 is arranged horizontally. A motor 170 is fixedly provided on the upper end surface of the support plate 160. A second transmission wheel 150 is fixedly provided on the power output shaft of the motor 170. The second transmission wheel 150 and the first transmission wheel 140 are arranged with an interval therebetween, and the second transmission wheel 150 and the first transmission wheel 140 are connected to each other through a transmission belt 180. When the motor 170 rotates, the winding wheel 120 rotates around the first axis.

[0030] The detection assembly includes a detection plate 210 and a telescopic rod 220. The detection plate 210 is horizontally arranged above the reel 120, and its length is consistent with that of the reel 120. The telescopic rod 220 is vertically arranged, with its lower end fixed to the detection plate 210 and its upper end fixed to the support plate 112. A first elastic member, a first spring, is disposed within the telescopic rod 220. In the initial state, the first spring is at its original length, and the telescopic rod 220 is at its longest state, so that the distance between the detection plate 210 and the side wall of the reel 120 is less than one diameter of the cable. During the cable reeling process, the cable is disposed between the detection plate 210 and the side wall of the reel 120. The cable is constantly squeezed by the detection plate 210 while being wound around the reel 120, causing the cable to be closely arranged in the radial direction of the reel 120. When the thickness of the cable wound on the winding wheel 120 increases, the cable pushes the detection plate 210 to move upward, and the detection plate 210 squeezes the first spring. When the detection plate 210 moves upward, the transmission ratio of the motor 170 driving the winding wheel 120 to rotate is adjusted through the speed change assembly.

[0031] In this embodiment, the speed shift assembly includes an adjustment plate 310. The first transmission wheel 140 is truncated cone-shaped. The smaller end of the first transmission wheel 140 is fixedly mounted on the rotating shaft of the winding wheel 120, with the larger end of the first transmission wheel 140 positioned in front of the smaller end. The second transmission wheel 150 is truncated cone-shaped. The dimensions of the second transmission wheel 150 are identical to those of the first transmission wheel 140. The smaller end of the second transmission wheel 150 is fixedly mounted on the power output shaft of the motor 170, with the smaller end of the second transmission wheel 150 positioned in front of the larger end. The second transmission wheel 150 is positioned above and below the first transmission wheel 140. A third slideway 117 is provided on the right side of the upper end surface of the base plate 111, extending forward and backward. The third slideway 117 is arranged parallel to the first axis. The adjustment plate 310 is a rectangular plate structure. The adjustment plate 310 is arranged vertically. The lower end of the adjustment plate 310 is slidably arranged along the third slide 117. A switching plate 320 is fixedly arranged in the middle of the adjustment plate 310. The switching plate 320 is arranged horizontally and extends left and right. A switching groove 321 running through the switching plate 320 is provided. The middle part of the transmission belt 180 is provided in the switching groove 321. When the adjustment plate 310 slides back and forth along the third slide 117, it drives the transmission belt 180 to move back and forth, so that the connection position of the transmission belt 180 with the first transmission wheel 140 and the second transmission wheel 150 is changed, thereby changing the transmission ratio between the first transmission wheel 140 and the second transmission wheel 150.

[0032] A pushing assembly is provided between the detection plate 210 and the adjustment plate 310. When the detection plate 210 gradually moves upward, the adjustment plate 310 slides along the third slideway 117, thereby changing the transmission ratio between the first transmission wheel 140 and the second transmission wheel 150. Specifically, the pushing assembly includes a pushing bent rod 330 and a fixed block 340. The fixed block 340 is a right-angled trapezoidal plate-shaped structure. The length of the upper base of the fixed block 340 is greater than the length of the lower base. The lower base of the fixed block 340 is fixedly connected to the upper end of the adjustment plate 310. The right-angled side of the fixed block 340 is in the same straight line as the front edge of the adjustment plate 310, so that the fixed block 340 has an inclined second inclined surface, and the lower end of the second inclined surface is in front of the upper end of the second section. The push rod 330 has a first section and a second section. The first section of the push rod 330 extends left and right, with the left end of the first section of the push rod 330 fixedly connected to the detection plate 210. The second section of the push rod 330 extends forward and backward, with the rear end of the second section of the push rod 330 fixedly connected to the right end of the first section of the push rod 330, and the front end of the second section of the push rod 330 abutting the second inclined surface of the fixed block 340. As the thickness of the cable wound around the reel 120 gradually increases, the detection plate 210 compresses the first spring, causing the second section of the push rod 330 to compress the fixed block 340, causing the adjustment plate 310 to slide forward, thereby slowing the speed at which the motor 170 drives the reel 120 to rotate.

[0033] The jacking assembly includes a slider 410, a jacking rod 420, and an adjustment unit. A slide rail 118 is fixedly mounted on the second bracket 114. The slide rail 118 extends forward and backward and is coplanar with the first axis. The slider 410 slides along the slide rail 118. The upper end surface of the slider 410 is provided with a first slideway 411 opening upward and a retaining groove 412. The first slideway 411 extends in a left-right direction, and the retaining groove 412 is parallel to and spaced apart from the first slideway 411. The slider 410 slides along the slide rail 118, and there is a constant resistance when the slider 410 slides along the slide rail 118. The tightening rod 420 is arranged horizontally and extends left and right. The left end of the tightening rod 420 is slidably arranged along the first slide 411. A protrusion 421 is fixedly provided on the left side of the lower end of the tightening rod 420. The protrusion 421 can slide along the limiting groove 412, and the left end of the tightening rod 420 is fixedly connected to the right end of the first slide 411 with a second elastic member. Specifically, the second elastic member is a second spring, and the second spring is in a stretched state, so that the tightening rod 420 always has a tendency to slide to the right. A plurality of limit blocks 413 are provided in the limit groove 412, each limit block 413 is a straight triangular prism structure, and each limit block 413 can slide in the depth direction of the limit groove 412, and a third spring is provided between the lower end of each limit block 413 and the inner end of the limit groove 412. The limit block 413 prevents the protrusion 421 from sliding to the right along the limit groove 412, so that the right end of the tightening rod 420 has a fixed distance from the winding wheel 120 or the cable wound on the winding wheel 120. As the cable gradually winds around the winding wheel 120, the cable gradually advances along the first axis direction of the winding wheel 120, so that the right end side wall of the tensioning rod 420 abuts against the side wall of the cable in the direction of advancement along the first axis direction. The cable pushes the tensioning rod 420 to move synchronously along the first axis direction, driving the slider 410 to slide along the slide rail 118. The slider 410 has a constant resistance when sliding along the slide rail 118. The tensioning rod 420 hinders the cable from moving along the first axis direction, so that the cable is tightly arranged around the winding wheel 120.

[0034] The adjustment unit is used to make the tensioning rod 420 slide along the first slide 411 by the distance of the cable diameter when the cable is wound to the end of the winding wheel 120. Specifically, the adjustment unit includes an adjustment baffle 510 and an adjustment rod 520. There are two adjustment baffles 510, and the two adjustment baffles 510 are fixedly set at both ends of the slide rail 118, and the adjustment baffles 510 are fixedly connected to the second bracket 114. Adjustment grooves 511 are provided on the two side walls close to each other of the two adjustment baffles 510. The opening directions of the two adjustment grooves 511 are arranged opposite to each other, and a plurality of guide blocks 512 are provided in each adjustment groove 511. Each guide block 512 is a right triangular prism structure, so that the guide block 512 has a first inclined surface. The right-angled side length of the guide block 512 is the same as the length of the cable diameter. Multiple guide blocks 512 are spaced apart along the adjustment slot 511. Within the same vertical plane extending forward and backward, one end of the vertical plane is located on the first inclined surface of the guide block 512 within one of the adjustment slots 511, and the other end of the vertical plane is located between the two guide blocks 512 within one of the adjustment slots 511, so that the guide blocks 512 within the two adjustment slots 511 are staggered. The adjustment rod 520 is arranged horizontally and parallel to the slide rail 118. The middle portion of the adjustment rod 520 is fixedly mounted on the left end of the tensioning rod 420, and the distance from the tensioning rod 420 to both ends of the adjustment rod 520 is the same. When the cable is wound around the end of the reel 120, the forward direction of the cable winding on the reel 120 is changed, and the thickness of the cable wound around the reel 120 increases. The cable gradually pushes the tensioning rod 420 to move along the first axis, causing the end of the adjustment rod 520 to gradually abut against the first inclined surface of the guide block 512. As the cable continues to push the tensioning rod 420 to move along the first axis, the adjustment rod 520 slides along the first inclined surface, driving the tensioning rod 420 to slide along the first slideway 411 a distance equal to the width of the guide block 512. At this point, the tensioning rod 420 no longer abuts against the cable. After the thickness of the cable wound around the reel 120 increases, the tensioning rod 420 again abuts against the side wall of the cable moving along the first axis.

[0035] In this embodiment, a damping rod 610 is fixedly mounted on the first bracket 113. The axis of the damping rod 610 is parallel to the first axis. The damping rod 610 defines a hollow damping chamber whose length matches the length of the reel 120. The damping chamber contains damping fluid. Two damping rings 611 are coaxially disposed within the damping chamber. The circumferential sidewalls of the damping rings 611 abut against the sidewalls of the damping chamber, and the two damping rings 611 are capable of sliding synchronously along the damping chamber. Both damping rings 611 are provided with a first notch 612, creating a flow path for the damping fluid on either side of the two damping rings 611. The two damping rings 611 are rotatably connected. When one damping ring 611 rotates relative to the other, the flow path of the damping fluid on either side of the two damping rings 611 changes. Specifically, when one damping ring 611 rotates clockwise or counterclockwise, the other damping ring 611 rotates counterclockwise or clockwise. A transmission assembly is provided between the tightening rod 420 and the damping ring 611. When the tightening rod 420 slides along the first slideway 411, the speed at which the cable moves along the first axis direction of the winding wheel 120 decreases, and the sliding speed of the two rotating rings in the damping cavity slows down. The two damping rings 611 rotate synchronously in opposite directions, reducing the flow channel of the damping fluid on both sides of the two damping rings 611, so that the sliding resistance of the two damping rings 611 inside the damping cavity remains unchanged.

[0036] In this embodiment, the transmission assembly includes a transmission rod 710 and a drive rod 720. The drive rod 720 includes a third section and a fourth section. The third section is horizontally arranged and extends horizontally. The third section is aligned with the tension rod 420, and the right end of the third section is fixedly connected to the left end of the tension rod 420. The slider 410 is fixedly provided with a guide rod 730. The guide rod 730 is horizontally arranged and extends horizontally. The fourth section of the drive rod 720 is vertically arranged, the upper end of the fourth section is fixedly connected to the left end of the third section, and the fourth section is slidably connected to the guide rod 730. The fourth section is provided with two second slideways 740 extending in a front-to-rear direction. The two second slideways 740 extend in a left-to-right direction and are inclined. The two second slideways 740 are arranged in opposite directions, so that the distance between the left ends of the two second slideways 740 is smaller than the distance between the right ends. Two transmission rods 710 are provided, each of which is U-shaped and consists of two long rods and a short rod. One end of the two long rods is fixedly connected by the short rod. The end of one long rod slides within the second slideway 740, while the end of the other long rod is fixedly connected to the damping ring 611. When the tensioning rod 420 slides leftward along the first slideway 411, the two transmission rods 710 slide along the second slideway 740, causing the two damping rings 611 to rotate simultaneously but in opposite directions, thereby reducing the flow channel area of ​​the damping fluid on both sides of the two damping rings 611.

[0037] In combination with the above embodiments, the operating principle and working process of the present invention are as follows:

[0038] During operation, the thickness of the cable wound on the reel 120 is detected and the rotation speed of the reel 120 is adjusted in a timely manner to maintain a stable length of cable wound on the reel 120 per unit time. The tensioning rod 420 and the detection plate 210 work together to keep the cables tightly arranged on the reel 120.

[0039] The detection plate 210 is arranged directly above the winding wheel 120. A telescopic rod 220 is fixedly connected between the upper end of the detection plate 210 and the support plate 112, and a first spring is arranged inside the telescopic rod 220. When the first spring is at its original length, the distance between the detection plate 210 and the winding wheel 120 is less than the diameter of the cable. When the cable is wound, the cable is passed between the winding wheel 120 and the detection plate 210, and the end of the cable is set in the locking hole. At this time, the motor 170 is started, and the electric power output shaft drives the second transmission wheel 150 to rotate. The second transmission wheel 150 is connected to the first transmission wheel 140 fixedly set on the rotating shaft of the winding wheel 120 by a transmission belt 180. When the motor 170 rotates, the winding wheel 120 rotates to wind the cable.

[0040] There is a fixed distance between the right end of the tensioning rod 420 and the side wall of the winding wheel 120, and the distance is smaller than the radius of the tensioning rod 420. As the winding wheel 120 rotates, the cable is wound on the winding wheel 120, and the cable is squeezed by the detection plate 210, so that the cable remains wound in a single layer on the winding wheel 120. When the cable is wound around the winding wheel 120 for one circle, the side wall of the cable abuts against the tensioning rod 420. When the cable moves along the first axis, the cable pushes the tensioning rod 420 to move forward synchronously along the first axis, and the tensioning rod 420 drives the slider 410 to slide along the slide rail 118. A damping rod 610 is fixedly provided on the left side of the slide rail 118. The damping rod 610 has a damping chamber inside. Two damping rings 611 are slidably provided in the damping chamber. The two damping rings 611 are rotatably connected. When the damping rings 611 slide in the damping chamber, the resistance encountered by the damping rings 611 depends on the sliding speed of the damping rings 611 and the size of the flow channel of the damping fluid on both sides of the damping rings 611. A driving rod 720 is fixedly provided on the left end of the slider 410. The damping rings 611 and the driving rod 720 are connected by a transmission rod 710. When the slider 410 slides along the slide rail 118, the driving rod 720 drives the two damping rings 611 to slide in the damping chamber through the transmission rod 710, so that the slider 410 encounters a certain amount of resistance when sliding along the slide rail 118, thereby causing the cables to be closely arranged in the direction of the first axis of the reel 120.

[0041] When the cable is wound around the end of the reel 120, the cable needs to change its forward direction along the first axis. During the process of the cable advancing along the first axis, the adjustment rod 520 fixed on the tension rod 420 first abuts against the first inclined surface of the guide block 512. As the cable continues to push the tension rod 420, the tension rod 420 slides to the left along the first slide 411 by a distance of one cable diameter. At the same time, the protrusion 421 set on the left side of the lower end of the tension rod 420 squeezes a limit block 413 to move into the limit groove 412, stretching the second spring between the tension rod 420 and the right end of the first slide 411. The limit block 413 in the limit groove 412 limits the rightward sliding of the tension rod 420, so that there is a fixed distance between the right end of the tension rod 420 and the outer wall of the cable.

[0042] The tightening rod 420 drives the driving rod 720 to move synchronously to the left. The two second slides 740 provided on the fourth section of the driving rod 720 are inclined in opposite directions. When the driving rod 720 moves to the left, the end of one of the long rods of each transmission rod 710 slides along the second slide 740, and the damping ring 611 fixedly connected to the end of the other long rod rotates, and the rotation directions of the two damping rings 611 are opposite, so that the first notches 612 provided on the two damping rings 611 are gradually blocked, and the area of ​​the flow channel of the damping fluid on both sides of the two damping rings 611 is reduced.

[0043] As the cable changes its winding direction on the reel 120, the thickness of the cable wound on the reel 120 increases, and the detection plate 210 is pushed by the cable toward the radially outer end of the reel 120. The detection plate 210 drives the push rod 330 to move upward synchronously. The second section of the push rod 330 presses and pushes the second inclined surface of the fixed block 340, causing the adjustment plate 310, to which the fixed block 340 is fixed, to move forward along the third slideway 117. The switching plate 320 is fixedly connected to the middle portion of the adjustment plate 310. A switching slot 321 is provided on the switching plate 320, and the middle portion of the transmission belt 180 passes through the switching slot 321. Driven by the adjustment plate 310, the switching plate 320 changes the meshing position of the transmission belt 180 and the first and second transmission wheels 140, 150, thereby changing the transmission ratio between the second transmission wheel 150 and the first transmission wheel 140 and reducing the rotation speed of the reel 120. Since the area of ​​the flow channel of the damping fluid on both sides of the two damping rings 611 is reduced, the resistance encountered by the damping rings 611 when sliding in the damping cavity remains unchanged, further ensuring that the horizontal tightness of the cable wound on the reel 120 remains consistent.

[0044] When the cable is completely wound around the reel 120 , the reel 120 is removed from the third fixing frame and replaced.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
