Description

Technical Field

[0001] The present invention relates to the technical field of power engineering, and in particular to a cable tensioning device for overhead laying of power cables. Background Art

[0002] Cable laying refers to the process of laying and installing cables along the surveyed route to form a cable line. According to the usage scenarios, it can be divided into several laying methods such as overhead, underground pipeline, direct burial, underwater, wall, and tunnel. Reasonably selecting the cable laying method is very important for ensuring the transmission quality, reliability, construction, and maintenance of the line.

[0003] During the process of overhead cable laying, the cable is successively fixed to the insulators on the crossarm of the utility pole. Due to gravity, the cable between two adjacent utility poles will sag downward. Therefore, when laying the cable overhead, it is necessary to tension the cable in a timely manner.

[0004] During the overhead process of the cable, manual tensioning is the most basic and simplest method. Only need to use manual tools such as wrenches, torque pliers, etc. to tension, and continuously increase the tension of the steel wire rope until it reaches the predetermined tension value.

[0005] However, this method is greatly limited by the stability and accuracy of the tension because it requires manual operation, making it difficult to ensure a certain tension accuracy. At the same time, the manual tensioning method has high requirements for the physical strength and skills of the operator, and requires relatively professional operation skills.

[0023] First embodiment:

[0024] Please refer to Figures 2 - 7 , in this embodiment, the traction mechanism 5 includes: a conveying member, a fastening member 510 and a limiting member 508; The conveying member includes a placement table 501.

The same guide roller 504 is rotatably arranged between the two limiting plates 505 to assist in conveying the cable. The placement table 501 is fixedly installed on the fixed table 7 through the fixed columns 507. A first traction belt 506 and a second traction belt 513 are respectively arranged on both sides of the placement table 501. The first traction belt 506 and the second traction belt 513 are arranged oppositely. Limiting grooves are respectively opened in the middle of the outer sides of the first traction belt 506 and the second traction belt 513. After the cable passes through the first traction belt 506 and the second traction belt 513, it will enter between the two limiting grooves, and the limiting grooves limit the cable. A first limiting wheel 502 is rotatably arranged on one side of the placement table 501. An auxiliary wheel 512 located on one side of the first limiting wheel 502 is rotatably arranged on the placement table 501. The first limiting wheel 502 and the auxiliary wheel 512 are respectively in contact with the second traction belt 513. A second conveying wheel 521 is arranged on the placement table 501 on the side opposite to the auxiliary wheel 512. The second conveying wheel 521 is in contact with the second traction belt 513. A first connecting rod 522 is fixedly installed at the bottom of the second conveying wheel 521. A transmission member is arranged below the first connecting rod 522. The transmission member includes a second connecting wheel 532. The first connecting rod 522 is rotatably arranged on the placement table 501. The second connecting wheel 532 is fixedly installed at the bottom of the first connecting rod 522. A second limiting wheel 509 is rotatably arranged on the placement table 501 on the side opposite to the first limiting wheel 502. An auxiliary wheel 534 located on one side of the second limiting wheel 509 is rotatably connected to the placement table 501. The second limiting wheel 509 and the auxiliary wheel 534 are respectively in contact with the first traction belt 506. A first conveying wheel 520 is arranged on the placement table 501 on the side opposite to the auxiliary wheel 534. The first conveying wheel 520 is in contact with the first traction belt 506. A second connecting rod 530 is fixedly installed at the bottom of the first conveying wheel 520. The second connecting rod 530 is rotatably arranged on the placement table 501. A first connecting wheel 529 is fixedly installed at the bottom of the second connecting rod 530. A cross transmission belt 531 is arranged outside the first connecting wheel 529 and the second connecting wheel 532. A second gear 528 is fixedly installed below the first connecting wheel 529. A first gear 527 is meshed and connected to one side of the second gear 528. A first rotating rod 519 is fixedly installed at one end of the first gear 527. A first fixing plate 535 is arranged outside the first rotating rod 519. The first fixing plate 535 is fixedly installed at the bottom of the placement table 501. A fifth rotating wheel 518 is fixedly installed at the end of the first rotating rod 519 opposite to the first gear 527. Specifically, when the motor works, the output end rotates to drive the third rotating wheel 206 on one side to rotate. When the third rotating wheel 206 rotates, it will simultaneously drive the second rotating wheel 205 on one side to rotate. Through the third belt 9 connected to the second rotating wheel 205, the fifth rotating wheel 518 on the other side is driven to rotate. When the second rotating wheel 205 rotates, it will drive the fourth gear 13 at one end to rotate. When the fourth gear 13 rotates, it will drive the third gear 10 on one side to rotate. When the third gear 10 rotates, it will drive the sixth rotating wheel 11 on one side to rotate.Then, the belt three 9 sleeved outside drives the rotating wheel five 518 on the other side to rotate. When the rotating wheel five 518 rotates, it drives the rotating rod one 519 on one side to rotate. When the rotating rod one 519 rotates, it drives the gear one 527 at one end to rotate. Since the gear one 527 meshes with the gear two 528, it drives the gear two 528 on one side to rotate. The rotation of the gear two 528 drives the connecting wheel one 529 above to rotate. The rotation of the connecting wheel one 529 drives the conveying wheel one 520 above to rotate through the connecting rod two 530. Through the rotation of the conveying wheel one 520, the traction belt one 506 on the outside can be driven to rotate. Since the connecting wheel one 529 is connected to the connecting wheel two 532 through the cross transmission belt 531, when the connecting wheel one 529 rotates, it drives the connecting wheel two 532 on one side to rotate in the opposite direction. When the connecting wheel two 532 rotates, it drives the conveying wheel two 521 above to rotate through the connecting rod one 522 above, so that the conveying wheel two 521 drives the traction belt two 513 on the outside to rotate. Since the connecting wheel one 529 and the connecting wheel two 532 rotate in the opposite direction, through the conveying wheel one 520 and the conveying wheel two 521, the traction belt one 506 and the traction belt two 513 rotate in the opposite direction. Through the mutual cooperation of the traction belt one 506 and the traction belt two 513, it assists in the conveying of the cable; When the traction belt one 506 and the traction belt two 513 cooperate with the winding roller 202 to wind the cable, since the power is transmitted by the motor, during the winding process, the gear four 13 drives the gear three 10 to rotate. The diameter of the gear four 13 is larger than the diameter of the gear three 10. Therefore, the number of rotation circles of the gear three 10 is more than the number of rotation circles of the gear four 13. The gear four 13 and the rotating wheel three 206 are coaxial, and the rotating wheel three 206 drives the winding roller 202 to rotate. The rotation of the gear three 10 drives the traction belt one 506 and the traction belt two 513 to rotate through the transmission part. The circumference of one rotation of the winding roller 202 is the same as the rotation distance of the traction belt one 506 and the traction belt two 513.

[0025] Further, the fastener 510 is arranged in the middle of the placing table 501. The fastener 510 includes a forward and reverse lead screw 5.2. A second placing groove 511 is formed in the middle of the placing table 501. The forward and reverse lead screw 5.2 is rotatably arranged in the middle of the second placing groove 511. Connecting blocks 5.4 are arranged at both outer ends of the forward and reverse lead screw 5.2. Card slots are formed on both sides of the second placing groove 511. Limiting blocks 5.3 are fixedly installed on both sides of the connecting block 5.4. The outer sides of the limiting blocks 5.3 are in contact with the inner walls of the card slots. The limiting blocks 5.3 are slidably arranged inside the card slots, thereby improving the stability of the connecting block 5.4 during movement. Firming blocks 5.5 are fixedly installed on the tops of the two connecting blocks 5.4. Fixing rods 5.6 are fixedly installed on one side of each of the two firming blocks 5.5. Placing frames 5.7 are fixedly installed at one ends of the two fixing rods 5.6. A number of pressing wheels 5.8 are rotatably arranged inside each placing frame 5.7. The two groups of pressing wheels 5.8 are respectively in contact with the first traction belt 506 and the second traction belt 513. Specifically, when the braking motor 5.1 works, the output end rotates to drive the forward and reverse lead screw 5.2 on one side to rotate. The forward and reverse lead screw 5.2 will drive the two connecting blocks 5.4 on the outside to move in opposite directions. When the connecting block 5.4 moves, it will drive the placing frame 5.7 and the pressing wheel 5.8 on one side to push the first traction belt 506 and the second traction belt 513, so that the first traction belt 506 and the second traction belt 513 approach each other, which is suitable for transporting different cables.

[0026] Further, the limiting member 508 is arranged on the placing table 501. The limiting member 508 includes a sliding rod 514.

Tightening wheels 516 are rotatably arranged on the tops of the two groups of sliders 517. The two tightening wheels 516 are respectively in close contact with the outer sides of the first traction belt 506 and the second traction belt 513. When the pressing wheel 5.8 pushes the first traction belt 506 and the second traction belt 513, the sliders 517 located on the outer sides of the first traction belt 506 and the second traction belt 513 will slide on the sliding rod 514 and squeeze the return spring 515. Therefore, the position of the tightening wheel 516 can be adjusted so that the tightening wheel 516 is always in close contact with the first traction belt 506 and the second traction belt 513.

When the motor works, the output end rotates to drive the third runner 206 on one side to rotate. The rotation of the third runner 206 drives the first runner 203 on one side to rotate through the first belt 204. The rotation of the first runner 203 will drive the winding roller 202 on one side to rotate, so as to wind the cable.

[0028] Refer to Figure 10 In addition, this embodiment further includes a guiding member 4. The guiding member 4 is arranged on one side of the winding member 2.

[0029] The working principle of the cable tensioning device for overhead laying of power cables provided by the present invention is as follows: First step: When tensioning the cable, the whole device is pushed by the roller 3 to move to the telegraph pole. Continuing to push the device enables the stabilizing member 6 to tightly hold the telegraph pole, thereby fixing the whole device.

[0030] Second step: After the whole device is fixed, first pass one end of the cable through one end of the guide roller 504, then pass the cable through the inside of the traction mechanism 5 and through the guiding ring 406. After that, the end of the cable is clamped on the winding roller 202 by the clamping plate 208, and then the clamping plate 208 is fixed by the fixing bolt 207, thereby fixing the end of the cable on the outside of the winding roller 202.

[0031] After placement, the motor works, and the output end rotates to drive the rotating wheel three 206 on one side to rotate. The rotation of the rotating wheel three 206 drives the rotating wheel one 203 on one side to rotate through the belt one 204. The rotation of the rotating wheel one 203 drives the winding roller 202 on one side to rotate, thereby winding the cable.

[0032] When the rotating wheel three 206 rotates, it will simultaneously drive the rotating wheel two 205 on one side to rotate. Through the belt three 9 connected to the rotating wheel two 205, it drives the rotating wheel five 518 on the other side to rotate. When the rotating wheel two 205 rotates, it drives the gear four 13 at one end to rotate. When the gear four 13 rotates, it drives the gear three 10 on one side to rotate. When the gear three 10 rotates, it drives the rotating wheel six 11 on one side to rotate, and then drives the rotating wheel five 518 on the other side to rotate through the externally sleeved belt three 9. When the rotating wheel five 518 rotates, it drives the rotating rod one 519 on one side to rotate. When the rotating rod one 519 rotates, it drives the gear one 527 at one end to rotate. Since the gear one 527 meshes with the gear two 528, it drives the gear two 528 on one side to rotate. The rotation of the gear two 528 drives the connecting wheel one 529 above to rotate. The rotation of the connecting wheel one 529 drives the conveying wheel one 520 above to rotate through the connecting rod two 530. Through the rotation of the conveying wheel one 520, it can drive the traction belt one 506 on the outside to rotate. Since the connecting wheel one 529 is connected to the connecting wheel two 532 through the cross transmission belt 531, when the connecting wheel one 529 rotates, it drives the connecting wheel two 532 on one side to rotate in the opposite direction. When the connecting wheel two 532 rotates, it drives the conveying wheel two 521 above to rotate through the connecting rod one 522 above, so that the conveying wheel two 521 drives the traction belt two 513 on the outside to rotate. Since the connecting wheel one 529 and the connecting wheel two 532 rotate in the opposite direction, through the conveying wheel one 520 and the conveying wheel two 521, the traction belt one 506 and the traction belt two 513 rotate in the opposite direction. Through the mutual cooperation of the traction belt one 506 and the traction belt two 513, it assists in conveying the cable.

[0033] During the conveying process, the braking motor 5.1 operates, and the rotation of the output end drives the rotation of the positive and negative lead screw 5.2 on one side. The positive and negative lead screw 5.2 drives the two connecting blocks 5.4 on the outside to move in opposite directions. When the connecting blocks 5.4 move, they drive the placement frame 5.7 and the pressing wheel 5.8 on one side to push the first traction belt 506 and the second traction belt 513, causing the first traction belt 506 and the second traction belt 513 to approach each other, which is suitable for the conveyance of different cables.

[0034] When the pressing wheel 5.8 pushes the first traction belt 506 and the second traction belt 513, the sliders 517 located outside the first traction belt 506 and the second traction belt 513 will slide on the slide rod 514, squeezing the return spring 515. Therefore, the position of the fastening wheel 516 can be adjusted so that the fastening wheel 516 is always in close contact with the first traction belt 506 and the second traction belt 513.

[0035] When the second runner 205 rotates, it drives the outer belt two 8 to rotate. Through the belt two 8, it drives the fourth runner 402 on one side to rotate. When the fourth runner 402 rotates, it drives the reciprocating lead screw 405 on one side to rotate. The reciprocating lead screw 405 drives the connecting platform 404 on the outside to move reciprocally. When the connecting platform 404 moves reciprocally, it drives the upper guiding ring 406 to move reciprocally, thereby arranging the cables in an orderly manner.

[0036] Compared with the related technology, the cable tensioning device for overhead laying of power cables provided by the present invention has the following beneficial effects: 1. The present invention provides a cable tensioning device for overhead laying of power cables. Through the setting of the traction mechanism 5, during use, the cable passes through between the first traction belt 506 and the second traction belt 513, and then the motor operates to drive the winding roller 202 to rotate. Through the cooperation of the third gear 10, the fourth gear 13, the third belt 9 and the transmission parts, the first traction belt 506 and the second traction belt 513 are driven to rotate in opposite directions to traction the cable, and cooperate with the winding roller 202 to wind the cable. Therefore, through the mutual cooperation of the winding part 2 and the traction mechanism 5, the automatic tensioning of the cable is realized, which greatly ensures the tension of the cable during the tensioning process, and the mechanical use improves the stability during the cable tensioning process; 2. Through the setting of the fastener 510, the braking motor 5.1 operates, and the rotation of the output end drives the rotation of the positive and negative lead screw 5.2 on one side. The positive and negative lead screw 5.2 drives the two connecting blocks 5.4 on the outside to move in opposite directions. When the connecting blocks 5.4 move, they drive the placement frame 5.7 and the pressing wheel 5.8 on one side to push the first traction belt 506 and the second traction belt 513, causing the first traction belt 506 and the second traction belt 513 to approach each other, which is suitable for the conveyance of different cables. Therefore, the distance between the first traction belt 506 and the second traction belt 513 can be adjusted in time, improving the applicable range for different cables.

[0037] The present invention provides a cable tensioning device for overhead laying of power cables. During the use of the winding member 2, the traction mechanism 5, and the guiding member 4, the motor in the winding member 2 is used as the power source to drive the traction mechanism 5 and the guiding member 4 to work. Therefore, the number of electrical components and the corresponding power systems used are greatly reduced, and the maintenance cost of the entire tensioning device is correspondingly reduced.

[0038] Second Embodiment: Based on the cable tensioning device for overhead laying of power cables provided in the first embodiment of the present application, the second embodiment of the present application proposes another cable tensioning device for overhead laying of power cables. The second embodiment is merely a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0039] The following further describes the second embodiment of the present invention in conjunction with the accompanying drawings and embodiments.

[0040] Please refer to Figure 8 and Figure 9 , the cable tensioning device for overhead laying of power cables further includes a stabilizing member 6, and the stabilizing member 6 is arranged at one end of the bottom plate 1; The fixing member 6 includes a mounting table 601 which is fixedly installed at one end of the bottom plate 1. At both ends of one side of the mounting table 601 away from the central position, clamping blocks are fixedly installed. On one side of each of the two clamping blocks, a placing cylinder 602 is fixedly installed. On one side inside each of the two placing cylinders 602, a placing cavity 605 is formed. An installation groove is formed on the clamping block, and the installation groove communicates with the placing cavity 605. On one side of the placing cavity 605 on the placing cylinder 602, a storage cavity 607 is formed. Through holes are formed in the middle of the two placing cylinders 602. Inside the two through holes, guide rods 608 are arranged. The diameter of the through holes is slightly larger than the diameter of the guide rods 608. The outer side of the guide rods 608 is in sliding fit with the inner wall of the through holes, which plays a limiting role on the guide rods 608 to prevent the guide rods 608 from being misaligned during movement. On the outer sides of the two guide rods 608, placing plates 606 are fixedly installed. The two placing plates 606 are arranged inside the storage cavity 607. On the outer sides of the two guide rods 608, fastening springs 609 are arranged. Both ends of the two fastening springs 609 are respectively fixedly installed on the placing plates 606 and the placing cylinders 602. At one end of each of the two guide rods 608, a fixing frame 604 is fixedly installed. Inside each of the two fixing frames 604, a ball 603 is rotatably arranged. The two balls 603 are arranged oppositely. Specifically, the whole device is pushed by the roller 3 to move. When it moves to the telegraph pole, the device is continuously pushed, so that the fixing member 6 clamps the telegraph pole, thereby fixing the whole device. When clamping, the mounting table 601 is pushed to move to the outside of the telegraph pole, so that the balls 603 are in contact with the outer wall of the telegraph pole. Then the device is continuously pushed, so that the outer side of the telegraph pole squeezes the balls 603, making the balls 603 push the fixing frame 604 on one side to move outwards, so that the fixing frame 604 moves inside the placing cavity 605. Then the placing plate 606 at the rear position squeezes the fastening spring 609, so that the telegraph pole moves between the mounting tables 601. After placing, the fastening spring 609 resets, thereby pushing the balls 603 outwards, making the balls 603 limit the whole device. Therefore, it can play a good role in stabilizing the whole tensioning device.

[0041] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present invention.
