Description

Technical Field

[0001] This invention relates to the field of traction device technology, specifically to a communication cable traction device and traction method. Background Technology

[0002] Communication cables are a general term for various wires used to transmit electrical or optical signals. They are widely used in the Internet, television and other data transmission systems and are one of the infrastructures of communication systems. The laying and retrieval of communication cables require a lot of manpower, so a traction machine is used to pull the communication cables during construction.

[0003] However, during operation, the mounting frame is supported by a rotatable bracket at the rear and by two movable wheels in front. When uneven ground is required, the continuous operation of the diesel engine causes the mounting frame to vibrate, resulting in poor stability. Furthermore, during the construction of communication cables, sand particles adhere to the cable surface. These sand particles enter the conveyor belt with the cable, and the pressure exerted by the conveyor belt on the cable affects the lifespan of the conveyor belt. Moreover, each time the cable is placed between the two guide rollers that limit the cable's vertical movement, the two upper guide rollers need to be adjusted sequentially. The guide rollers are adjusted by sliding the adjusting block against the mounting shell, and the adjusting block is fixed by bolts after sliding, which results in slow adjustment efficiency.

The adjusting frame 508 is fixedly connected to the right side of the adjusting block 502. A gear ring 509 is rotatably connected inside the adjusting frame 508. A positioning block 503 is detachably connected to the gear ring 509. A cleaning brush 504 is fixedly connected to the positioning block 503. The cleaning brush 504 is slidably connected to the gear ring 509. Two rotating shafts 505 are rotatably connected inside the adjusting frame 508. A gear 506 is fixedly connected to the rotating shaft 505. The gear 506 meshes with the gear ring 509. A pulley 507 is fixedly connected to the rotating shaft 505. The two pulleys 507 are driven by a belt.

[0041] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 10 and Figure 11As shown, a second lead screw 510 is rotatably connected to the guide frame 501, and the second lead screw 510 is threadedly connected to the adjusting block 502. A motor 511 is installed behind the adjusting frame 508, and the upper rotating shaft 505 is fixedly connected to the output shaft of the motor 511. A crank handle 307 is fixedly connected above the first lead screw 306. An air blowing structure 9 is provided between the mounting shell 2 and the adjusting frame 508. The air blowing structure 9 includes a connecting block 901 fixedly connected to the adjusting frame 508 and a first connecting pipe 902 installed in the connecting block 901. The first connecting pipe 902 has multiple air holes 903. The mounting shell... An air pump 905 is installed on the 2nd mounting plate. The air pump 905 has a second connecting pipe 904 installed at its intake port. The other end of the second connecting pipe 904 is connected to the first connecting pipe 902. When the first lead screw 306 is rotated by the crank handle 307, the first lead screw 306 causes the adjusting plate 304 to move downwards. The adjusting plate 304 causes the guide rod 308 to slide against the mounting plate 305. The adjusting plate 304 then causes the upper mounting frame 301 to move downwards. When the upper mounting frame 301 brings the upper conveyor belt and cable into contact, the diesel engine 10 can be started. When the output shaft of the diesel engine 10 rotates, it drives one of the lower mounting shafts 302 to rotate. When the 02 rotates, it drives the transmission roller 303 to rotate, which in turn drives the conveyor belt to rotate. The conveyor belt pulls the cable during operation. During this pulling process, the motor 511 is started. The output shaft of the motor 511 rotates, which in turn drives the upper rotating shaft 505 to rotate. The rotating shaft 505 drives the pulley 507 to rotate, which in turn drives the lower rotating shaft 505 to rotate via the belt. The rotating shaft 505 drives the gear 506 to rotate, which in turn drives the gear ring 509 to rotate. The gear ring 509 then drives the cleaning brush 504 to rotate, which cleans the sand particles from the cable surface. To prevent sand particles from affecting the service life of the conveyor belt, the air pump 905 can be started during cleaning. When the air pump 905 is running, the airflow enters the first connecting pipe 902 from the second connecting pipe 904 and then flows out from the air hole 903 on the first connecting pipe 902. At the same time, the airflow blows away the cleaned sand particles. When it is necessary to adjust the position of the adjusting frame 508 according to the cable diameter, the second lead screw 510 is rotated. The second lead screw 510 will drive the adjusting block 502 to slide in the guide frame 501. The adjusting block 502 will drive the adjusting frame 508 to move, and the adjustment is completed. Different cleaning brushes 504 can be replaced according to the cable diameter.

[0042] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the first guiding structure 4 includes two vertical plates 401 fixedly connected to the mounting bracket 1. A first connecting shaft 402 is rotatably connected to the vertical plate 401. A first guiding roller 403 is fixedly connected to the first connecting shaft 402. Two guide rails 404 are fixedly connected to the right side of the mounting shell 2. The chute in the guide rail 404 has a "convex" shape structure. An installation block 405 is slidably connected in the guide rail 404. A second connecting shaft 406 is rotatably connected to the installation block 405. A second guiding roller 407 is fixedly connected to the second connecting shaft 406. The limiting structure 6 includes a guiding sleeve 601 fixedly connected to the installation block 405 and a limiting plate 602 slidably connected in the guiding sleeve 601. A plurality of limiting grooves 603 are provided on the guide rail 404. The limiting plate 602 is engaged with one of the limiting grooves 603. A sliding rod 604 is fixedly connected to the right end of the limiting plate 602. The sliding rod 604 is slidably connected to the installation block 405. A tension spring 605 is fixedly connected between the sliding rod 604 and the guiding sleeve 601. A pull rod 606 is fixedly connected between the two sliding rods 604. A second guiding structure 7 is provided on the vertical plate 401. The second guiding structure 7 includes a fixed frame 701 fixedly connected to the vertical plate 401 and two adjusting rods 702 slidably connected in the fixed frame 701. A third connecting shaft 703 is rotatably connected to the adjusting rod 702. A third guiding roller 704 is fixedly connected to the third connecting shaft 703. A third screw rod 705 is rotatably connected in the fixed frame 701. The adjusting rod 702 is threadedly connected to the third screw rod 705. The thread directions at both ends of the third screw rod 705 are opposite. At this time, the cable can pass through the first guiding rollers 403 on the two vertical plates 401, and then by pulling the pull rod 606 to the right, when the pull rod 606 moves to the right, it带动 the sliding rod 604 to move to the right. The sliding rod 604 will cause the tension spring 605 to stretch. At the same time, the sliding rod 604带动 the limiting plate 602 to no longer be engaged with the limiting groove 603. At this time, the pull rod 606带动 the two installation blocks 405 to move downward. The installation block 405 will带动 the second guiding roller 407 to move downward. When the second guiding roller 407 moves to a certain position, release the pull rod 606, and the limiting plate 602 is engaged with the limiting groove 603 under the action of the tension spring 605. At this time, the adjustment of the position of the second guiding roller 407 is completed. By engaging the limiting plate 602 with the guide rail 404, when the position of the second guiding roller 407 needs to be adjusted, it is convenient to quickly adjust, improving the adjustment efficiency of the second guiding roller 407. At the same time, the third screw rod 705 can be rotated. Since the thread directions at both ends of the third screw rod 705 are opposite, the third screw rod 705 can drive the two adjusting rods 702 to move towards each other by threading. The adjusting rod 702带动 the third connecting shaft 703 and the third guiding roller 704 to move. When the two third guiding rollers 704 move to a certain position, the cable is guided by the cooperation of the first guiding roller 403, the second guiding roller 407 and the two third guiding rollers 704.To prevent the cable from shifting on the conveyor belt.

[0043] Specifically, such as Figure 1 , Figure 4 , Figure 6 , Figure 8 , Figure 9 , Figure 11 , Figure 12 and Figure 13 As shown, the support structure 8 includes two hydraulic rods 801 mounted on the mounting frame 1 and a connecting plate 802 fixedly connected to the telescopic ends of the hydraulic rods 801. Two support rods 803 are slidably connected in the connecting plate 802. A fixed cone 804 is slidably connected in each support rod 803. A fixed plate 805 is fixedly connected above the fixed cone 804. A first knob 806 is threaded into each support rod 803, and the first knob 806 abuts against the fixed cone 804. A second knob 807 is threaded into the connecting plate 802, and a fixed post 808 is fixedly connected to the second knob 807. Multiple fixing holes 809 are provided in each support rod 803, and the fixed post 808 engages with one of the fixing holes 809. First, the mounting frame 1 is moved to a designated position. Then, by activating the hydraulic rods 801, the telescopic end of the first hydraulic rod 801 extends, causing the connecting plate 802 to move downwards. The connecting plate 802 then causes the support rods 803 to move downwards. The four support rods 803... 3. When moving downwards, it will lift the mounting bracket 1, preventing the moving wheels from contacting the ground and improving the stability of the mounting bracket 1. When using a traction machine on uneven ground, the support rod 803 can slide against the connecting plate 802. After sliding a certain distance, by rotating the second knob 807, the second knob 807 engages with the threaded connection of the connecting plate 802, causing the fixing column 808 to move towards the fixing hole 809, thus engaging the fixing column 808 with the fixing hole 809. This is achieved through the connection between the support rod 803 and the connecting plate 802. 2. The sliding fit facilitates the adjustment of the height of each support rod 803 on uneven ground, improving the stability of the mounting frame 1 on uneven ground. At the same time, when using the traction machine on soft ground, the operator can insert the fixed cone 804 into the soil. When the fixed cone 804 is not needed, it can be slid upward to a certain position, and then the first knob 806 can be turned to make the first knob 806 press against the fixed cone 804 to fix the fixed cone 804 and prevent the fixed cone 804 from sliding freely.

[0044] A method for pulling a communication cable pulling device includes the following steps:

[0045] S1: Move the mounting frame 1 to the designated position. The support components in the support structure 8 can be extended to support the entire mounting frame 1, so that the moving wheels no longer contact the ground.

[0046] S2: After the mounting bracket 1 is supported, the communication cable is passed through the traction structure 3. The traction structure is driven by the output shaft 10 of the diesel engine 10, so that the traction structure 3 pulls the communication cable. During the pulling, the first guide structure 4, the limiting structure 6 and the second guide structure 7 cooperate to guide the communication cable.

[0047] S3: When the communication cable is pulled, the cleaning structure 5 and the air blowing structure 9 clean the sand particles adhering to the surface of the cable.

[0048] In use, the mounting frame 1 is first moved to the designated position. Then, by activating the hydraulic rod 801, the extension end of the first hydraulic rod 801 causes the connecting plate 802 to move downwards. The connecting plate 802 then causes the support rods 803 to move downwards. When the four support rods 803 move downwards, they support the mounting frame 1, preventing the moving wheels from contacting the ground and improving the stability of the mounting frame 1. When using a traction machine on uneven ground, the support rods 803 can slide against the connecting plate 802. After sliding a certain distance, the second knob 807 is rotated. When the second knob 807 rotates, it engages with the threaded connection of the connecting plate 802 to fix it in place. The column 808 moves toward the fixing hole 809, so that the fixing column 808 engages with the fixing hole 809. The support rod 803 slides with the connecting plate 802, which facilitates the adjustment of the height of each support rod 803 on uneven ground, improving the stability of the mounting frame 1 on uneven ground. At the same time, when using the traction machine on soft ground, the operator can insert the fixing cone 804 into the soil. When the fixing cone 804 is not needed, the fixing cone 804 is slid upward to a certain position, and the first knob 806 is turned to make the first knob 806 press against the fixing cone 804 to fix the fixing cone 804 and prevent the fixing cone 804 from sliding freely.

[0049] At this point, the cable can be passed through the first guide roller 403 on the two vertical plates 401. Then, by pulling the lever 606 to the right, the lever 606 moves to the right, causing the slide bar 604 to move to the right. The slide bar 604 will cause the tension spring 605 to extend. At the same time, the slide bar 604 will cause the limiting plate 602 to no longer engage with the limiting groove 603. At this time, the lever 606 will cause the two mounting blocks 405 to move downward. The mounting blocks 405 will cause the second guide roller 407 to move downward. When the second guide roller 407 moves to a certain position, the lever 606 is released, and the limiting plate 602 engages with the limiting groove 603 under the action of the tension spring 605. At this time, the position of the second guide roller 407 is adjusted. The position plate 602 engages with the guide rail 404, facilitating quick adjustment of the position of the second guide roller 407 when adjustment is needed, thus improving the adjustment efficiency of the second guide roller 407. Simultaneously, by rotating the third lead screw 705, which has opposite thread directions at both ends, the third lead screw 705 can drive the two adjusting rods 702 to move in opposite directions. The adjusting rods 702 drive the third connecting shaft 703 and the third guide roller 704 to move. When the two third guide rollers 704 move to a certain position, the first guide roller 403, the second guide roller 407, and the two third guide rollers 704 work together to guide the cable, preventing the cable from deviating on the conveyor belt.

[0050] At this time, the first lead screw 306 is rotated by the crank handle 307. When the first lead screw 306 rotates, it drives the adjusting plate 304 to move downward. The adjusting plate 304 drives the guide rod 308 to slide against the mounting plate 305. The adjusting plate 304 will drive the upper mounting frame 301 to move downward. When the upper mounting frame 301 makes the upper conveyor belt and cable close together, the diesel engine 10 can be started. When the output shaft of the diesel engine 10 rotates, it drives one of the lower mounting shafts 302 to rotate. When the mounting shaft 302 rotates, it drives the transmission roller 303 to rotate. When the transmission roller 303 rotates, it drives the conveyor belt to rotate. When the conveyor belt rotates, it pulls the cable for construction. During traction, the motor 511 is started. When the output shaft of the motor 511 rotates, it drives the upper rotating shaft 505 to rotate. The rotating shaft 505 drives the pulley 507 to rotate. The pulley 507 drives the lower rotating shaft 505 to rotate through the belt. The rotating shaft 505 drives the gear 50 When gear 506 rotates, it drives gear ring 509 to rotate, which in turn drives cleaning brush 504 to rotate. Cleaning brush 504 cleans sand particles from the cable surface, preventing them from affecting the service life of the conveyor belt. During cleaning, air pump 905 can be started. When air pump 905 is running, airflow enters from the second connecting pipe 904 into the first connecting pipe 902 and then flows out from the air hole 903 on the first connecting pipe 902. At the same time, the airflow blows away the cleaned sand particles. When the position of adjusting frame 508 needs to be adjusted according to different cable diameters, the second lead screw 510 is rotated.
