Description
Technical Field
[0001] This utility model relates to the field of cable laying technology, specifically to a convenient cable laying guide device for power engineering. Background Technology
[0002] Power cables are the "invisible pillars" of modern life. They ensure the daily power supply for homes, drive the stable operation of urban transportation, medical and other infrastructure, support industrial production and the digital economy, facilitate the access of new energy sources, promote green development, and make life more convenient, safe and sustainable.
[0003] The environment for laying power cables is complex, especially in narrow spaces or conduit areas. Traditional traction methods typically use guide wheels to guide the cables. Guide wheels usually require drilling holes in the wall and using bolts for fixing, which makes fixing the guide wheels troublesome and inconvenient. Power cables need to be pulled from the other end, and fixed-size guide wheels are difficult to adapt to cables of various diameters. If the guide wheel is too large, the cable will deviate; if the guide wheel is too small, the cable sheath will be damaged due to compression. Moreover, the pulling force at the other end of the conduit is difficult to maintain. When the pulling force stops, the cable reel will not stop rotating immediately, causing the cable to fall off the reel, resulting in cable knots and reducing laying efficiency. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figures 1-6As shown, a convenient cable laying guide device for power engineering includes a platform 1, and further includes: a disc 2 disposed on the top of the platform 1 for rotating the cable; connecting posts 3 are fixedly connected to the four corners of the disc 2; rollers 4 are rotatably connected to the outer sides of the connecting posts 3; a column 5 is rotatably connected to the center of the disc 2; a support plate 16 is fixedly connected to the outer side of the column 5; the bottom of the support plate 16 is rotatably connected to the rollers 4; a fixed post 6 is slidably connected to the top of the disc 2; a brake pad 7 is fixedly connected to the outer side of the fixed post 6; a lever 8 is fixedly connected to the other end of the brake pad 7; a support rod 9 is rotatably connected to the inside of the lever 8; the bottom of the support rod 9 is fixedly connected to the top of the disc 2; and a connecting block 10 is fixedly connected to the outer side of the connecting posts 3. A spring 11 is fixedly connected to one side of the connecting block 10, and the other end of the spring 11 is fixedly connected to one side of the lever 8. A limit post 12 is fixedly connected to one side of the top of the lever 8, and a limit plate 13 is fixedly connected to the outside of the limit post 12. There are two limit plates 13. A sliding plate 14 is slidably connected inside the lever 8, and a limit post 25 is fixedly connected to one side of the sliding plate 14. The platform 1 facilitates the fixing of the disc 2. The disc 2 is hollow inside, which facilitates the installation of the connecting post 3 on the side of the disc 2. Rollers 4 are set on the outside of the connecting post 3 to facilitate the support and rotation of the support plate 16. The column 5 facilitates the rotation of the support plate 16 connected to the column 5. When the column 5 stops rotating, the support plate 16... It will also stop rotating. The upper part of the support plate 16 can be used to place the cable reel. By setting the fixed column 6, brake pad 7, lever 8 and support rod 9, the movement of the column 5 can be easily controlled. When the spring 11 is tightened, one end of the lever 8 is close to the side with the spring 11. Under the action of the lever principle, the other end of the lever 8 moves away from the column 5, thereby causing the brake pad 7 to press tightly against the column 5. The column 5 cannot rotate under the action of friction. When the spring 11 is stretched, one end of the lever 8 moves away from the side with the spring 11. Under the action of the lever principle, the other end of the lever 8 moves close to the column 5, thereby causing the brake pad 7 to release the column 5, allowing the column 5 to rotate. The limit column 12 can be set to facilitate the installation of the limit plate 13. 13 can prevent the cable from detaching from the first limiting post 12 when it is pulled. Through the cooperation of the sliding plate 14 and the second limiting post 15, when the sliding plate 14 is pushed into the inside of the lever 8, the second limiting post 15 can be tightly attached to the limiting plate 13. In this way, the cable will not detach from the second limiting post 15 after it stops being pulled. This ensures that the force of the cable being pulled can always act on the lever 8, thereby affecting the extension and contraction state of the first spring 11, so as to control the column 5 to allow rotation and prohibit rotation. Thus, when the force of pulling the cable is maintained, the reel can continue to rotate. When the pulling force is removed, under the action of the first spring 11, the brake pad 7 is tightly attached to the column 5, so that the column 5 and the support plate 16 stop rotating under the action of the friction of the brake pad 7.
[0016] Two fixed boxes 17 are installed on the top of platform 1 to support the guide device. The fixed boxes 17 have a limiting groove 18 inside. A bidirectional threaded rod 19 is rotatably connected inside the fixed box 17. A handle 20 is fixedly connected to one end of the bidirectional threaded rod 19. A threaded sleeve 21 is threadedly connected to the outside of the bidirectional threaded rod 19. A positioning rod 22 is fixedly connected to one side of the threaded sleeve 21. A positioning head 23 is fixedly connected to one end of the positioning rod 22. A limiting block 24 is fixedly connected to the other side of the threaded sleeve 21. The limiting block 24 is slidably connected to the limiting groove 18. The bidirectional threaded rod 19 can be easily rotated by the handle 20. When the bidirectional threaded rod 19 is rotated, the threaded sleeves 21 move closer to each other or further away from each other under the action of the limiting block 24 and the limiting groove 18. When the threaded sleeves 21 move further away from each other, the positioning rod 22 will move closer to the inner wall of the pipe. The positioning rod 22 will drive the positioning head 23 to squeeze the pipe.
[0017] It should be noted that the positioning head 23 is made of rubber to prevent slippage between the positioning head 23 and the pipe.
[0018] A support column 25 is fixedly connected between two fixed boxes 17. A connecting rod 26 is fixedly connected between the support columns 25. A spring 27 is sleeved on the outer side of the connecting rod 26. A transition block 28 is slidably connected to the outer side of the connecting rod 26. The transition block 28 is positioned between the springs 27. A connecting rod 29 is fixedly connected between the transition blocks 28. A guide wheel 30 is rotatably connected to the outer side of the connecting rod 29. The support column 25 facilitates the fixing of the connecting rod 26. A spring 27 is sleeved on the outer side of the connecting rod 26. Spring 27 and adapter block 28 are connected. Adapter block 28 is pressed between spring 27. Connecting rod 29 is fixed between adapter blocks 28. Guide wheel 30 is rotatably connected to the outer side of connecting rod 29. When the direction of the force pulling the cable changes, the guide wheel 30 on the pressed side will drive adapter block 28 to press spring 27 on one side. Spring 27 on the other side will extend and drive adapter block 28 and guide wheel 30 on the other side to continuously press the cable, preventing the cable from shifting and adapting to cables of various diameters.
[0019] It should be noted that there are two sets of the above structures, one set vertically and one set horizontally, which can adaptively adjust the clamping position under the action of spring 27 when the direction of force changes when the cable is pulled.
[0020] Working principle: Place the device in front of the pipe to be passed through, then turn the handle 20. The positioning rod 22 and the positioning head 23 move away from each other under the action of the double-threaded rod 19 and the threaded sleeve 21, thus clamping the inner wall of the pipe. This eliminates the need for drilling holes and using bolts to fix the device, improving assembly and disassembly efficiency. After the cable reel is placed on top of the support plate 16, pull out one end of the cable and pass it between the two limiting plates 13. Then push the slide plate 14 into the lever 8, bringing the second limiting post 15 close to the limiting plate 13, ensuring that the cable remains between the first limiting post 12 and the second limiting post 15. Then, continue to pass one end of the cable through the horizontal and vertical guide wheels 30. Pull the cable at the other end of the pipe. The tension of the cable will be transmitted to the lever 8. Under the action of the support rod 9, the inner end of the lever 8 will touch the column 5, thus releasing the brake pads. 7. This allows the column 5 and support plate 16 to rotate, which in turn causes the cable reel to rotate, pulling out more cable. When the direction of the tension on the cable at the other end of the pipe changes, the cable will squeeze one of the guide wheels 30. The other guide wheel 30, under the action of spring 27, will drive the other guide wheel 30 to continue squeezing the cable, preventing the cable from deviating. This method can adapt to cables of various diameters. When the force pulling the cable is removed, the cable reel will continue to rotate, and the cable will loosen. The cable will no longer exert force on the lever 8, and spring 11 will begin to contract, causing the brake pad 7 to press tightly against the column 5. Under the action of friction, the column 5 and support plate 16 will stop rotating, and the cable reel will also stop rotating. This effectively prevents the cable from detaching and knotting due to the inertial rotation of the reel, ensuring the smoothness of construction and improving the efficiency and quality of power engineering cable laying.
