Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of power transmission and transformation engineering, and particularly relates to a cable anti-loosening component for a power transmission and transformation engineering iron tower and an installation method thereof. Background Art
[0002] Cables are laid overhead or underground to cooperate with iron towers to build a power distribution network system and achieve efficient power transmission. When installed on an iron tower, the cables need to be fixed by special brackets and equipped with lightning protection devices to cope with lightning strike risks. The selection of cables needs to consider factors such as voltage level, current carrying capacity, and environmental conditions to ensure the safe and stable operation of the power system. At the same time, the fixation of the cables on the iron tower needs to meet the requirements of mechanical properties and durability to ensure the safety and reliability of the cables. When connecting to the iron tower, they will be connected to tower poles of different shapes;
[0003] The existing technical solutions mentioned above have the following defects: Cable connection pieces are usually fixed to tower poles by bolts. Under the action of external vibration, impact, or temperature change, the bolts are prone to loosen due to the expansion of the thread clearance, resulting in connection failure, which may cause displacement of the cable fixing points. When connecting to tubular tower poles, due to the shape defect, the bead width is too thick, resulting in a decrease in connection strength and prone to shaking and offset. Summary of the Invention
[0004] The purpose of the present invention is to provide a cable anti-loosening component for a power transmission and transformation engineering iron tower and an installation method thereof to solve the defect that the existing cable anti-loosening components for power transmission and transformation engineering iron towers are prone to loosening.
[0005] To solve the above technical problems, the present invention provides the following technical solutions: A cable anti-loosening component for a power transmission and transformation engineering iron tower and an installation method thereof, including a connection piece and a clamping block installed on one side thereof.

[0006] Preferably, the stabilizing structure includes connecting plates, the connecting plates are provided at both ends inside the connection piece, and tubes are provided at the tops of the connecting plates, and the tops of the tubes are connected to the connection piece.
[0007] Preferably, large discs are provided on both sides of the bottom of the stable structure, and a sliding structure is formed between the large discs and the connecting plate. Medium discs are provided on both sides of the bottom of the large discs, and a sliding structure is formed between the medium discs and the large discs.

[0008] Preferably, pistons are provided inside the tubes, and first springs are installed on the tops of the pistons. Inner cavities are provided on the inner walls of the tubes, and oil inlet holes are provided on both sides of the top of the inner cavities. Oil outlet holes are provided on both sides of the bottom of the inner cavities. The oil outlet speed is controlled through the oil outlet holes, and the resilience of the first spring is reduced to achieve the buffering effect.
[0009] Preferably, a fixing block is installed on one side of the clamping block, and clamping blocks are provided at both ends of the side of the fixing block away from the clamping block. Screws are installed at both ends of the clamping block.
[0010] Preferably, a clamping structure is formed between the clamping block and the limiting block, and the opposite sides of the clamping block and the limiting block are both beveled. When the clamping block is inserted, it can directly slide to squeeze the limiting block to one side.
[0011] Preferably, convex blocks are provided at both ends of the connecting plate, and pull rings are installed on one side of the convex blocks. A third spring is installed on one side of the connecting plate. The opposite sides of the convex blocks and the connecting block are both beveled. Pulling the convex blocks causes extrusion on the connecting block to drive the movement of the limiting block.
[0012] Preferably, the anti-loosening structure includes first ratchet teeth installed at both ends of one side of the clamping block. Second ratchet teeth are provided outside the screws on one side of the first ratchet teeth. A pressing block is provided on the top of the first ratchet teeth. A clamping structure is formed between the first ratchet teeth and the second ratchet teeth.
[0013] Preferably, a movable ring is provided on one side of the first ratchet tooth, and a fourth spring is sleeved outside the movable ring. Connecting shafts are provided at the corners on one side of the first ratchet tooth, and connecting holes are provided on the side walls of the clamping block outside the connecting shafts. The connecting shafts can limit the first ratchet teeth to prevent them from rotating.
[0014] An installation method for a cable anti-loosening component for a transmission and transformation project iron tower includes the following steps:
[0015] S1. First, fix the connecting piece to the tower pole. The connecting piece is snapped onto the outside of the tower pole. Press the connecting piece to one side and then insert the clamping block through the connecting piece to the bracket. One side of the clamping block pushes the limiting block to move outward. When the protrusion on one side of the clamping block is pushed away from the limiting block, the limiting block is pushed to reset under the tension of the second spring and is clamped and fixed with the clamping block;
[0016] S2. After the connecting piece and the tower pole are fixed, due to the different diameters of the tower poles, under the elastic action of the first spring, the connecting plate is pushed to squeeze one side of the tower pole. Due to the shape and sliding fit between the large disk, the medium disk and the small disk, when being squeezed, it can be clamped along with the change of the outer shape of the tower pole, fixing the tower pole and the clamping block, and preventing the connecting piece from shifting and shaking on the tower pole;
[0017] S3. Then pass the cable through between the clamping block and the fixing block, and then rotate the screw to lock it. Continuously lock and fix between the clamping block and the fixing block to realize the fixed clamping of the cable. Under the action of the second ratchet and the first ratchet, the screw cannot reverse, thus avoiding the loosening phenomenon and strengthening the firmness.
[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The cable anti-loosening component for the transmission and transformation project iron tower can quickly assemble and limit the connecting piece and the tower pole, has a strong and stable fixing effect, has a limiting effect between the connecting piece and the tubular tower pole, improves the connection strength, and when fixing the cable, through the cooperation between the ratchets, it can play an anti-loosening effect and enhance the stability of the line contact;
[0019] By setting a limiting structure, a clamping block is fixed on one side of the fixing block. By directly inserting the clamping block and generating a clamping and fixing between it and the limiting block, the connecting piece and the tower pole can be connected, realizing the quick connection of the connecting piece, reducing the operation difficulty, and under the action of the tension of the second spring, the clamping block and the limiting block always maintain a clamped state without external force, avoiding the phenomenon of loosening and detachment and increasing the firmness;
[0020] Further, when the connecting piece and the tower pole are fixed, due to the tube shape of the tower pole, when squeezing the disk, through the sliding fit between the large, medium and small disks, the disk clamps one side of the tower pole in an arc shape, filling the phenomenon of over-thick root face to a certain extent, improving the connection strength and enhancing the stability;
[0021] Further, hydraulic oil is arranged inside the tube body. When there is shaking and vibration, the piston compresses the hydraulic oil, and through the control of the return flow of the hydraulic oil through the oil outlet hole, the too-fast return force of the first spring is avoided, realizing the slow reset of the piston, so that the cable assembly plays a shock-absorbing and buffering effect;
[0022] By setting an anti-loosening structure, a second ratchet is arranged on one side of the screw. When rotating to lock and fix the cable, the ratchets between the second ratchet and the first ratchet slip, and tightening and fixing can be realized, but when rotating in the reverse direction, the ratchets between the first ratchet and the second ratchet engage, making the screw unable to rotate in the reverse direction, thus playing an anti-loosening effect on the fixing of the cable and ensuring the stability of the contact between the iron tower and the transmission line.

DETAILED DESCRIPTION
[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0035] Please refer to Figures 1 - 10 , a cable anti-loosening component for a transmission and transformation project iron tower and its installation method provided by the present invention, including a connecting piece 1 and a clamping block 3 installed on one side thereof. A stabilizing structure 2 is arranged inside the connecting piece 1, a limiting structure 4 is installed at the bottom of one side of the connecting piece 1, and an anti-detachment structure 5 is arranged on one side of the clamping block 3; the limiting structure 4 includes a bracket 41, the bracket 41 is installed on the side wall of the connecting piece 1, a connecting plate 45 is arranged in the middle of the bracket 41, and limiting blocks 42 are installed at both ends of the connecting plate 45. Connecting blocks 44 are arranged at opposite ends of the limiting blocks 42, and second springs 43 are installed at the other ends of the limiting blocks 42. A fixing block 32 is installed on one side of the clamping block 3, and clamping blocks 33 are arranged at both ends of the fixing block 32 away from the clamping block 3. A clamping structure is formed between the clamping blocks 33 and the limiting blocks 42. The opposite sides of the clamping blocks 33 and the limiting blocks 42 are both beveled. Convex blocks 451 are arranged at both ends of the connecting plate 45, and pull rings 453 are installed on one side of the convex blocks 451. A third spring 452 is installed on one side of the connecting plate 45. The opposite sides of the convex blocks 451 and the connecting blocks 44 are both beveled.
[0036] Refer to Figure 3 , Figure 4 and Figure 7 As shown, the connecting piece 1 is inserted into the outside of the tower pole from one side. Press the connecting piece 1 and insert it downward so that the clamping block 3 passes through the connecting piece 1 to the bracket 41. Because the opposite sides of the clamping block 3 and the limiting block 42 are both beveled, when the clamping block 3 is inserted, it pushes the limiting block 42 to move outward. When the protrusion on one side of the clamping block 3 is inserted away from the limiting block 42, the limiting block 42 is pushed to reset under the tension of the second spring 43, and is clamped and fixed with the protrusion of the clamping block 3, so as to facilitate assembly and not easy to loosen. When disassembly is required, pull the pull ring 453 to drive the convex block 451 to displace outward. Because the opposite sides of the convex block 451 and the connecting block 44 are both beveled, when the convex block 451 displaces, it pushes the connecting block 44 to move outward. The connecting block 44 and the limiting block 42 are connected. When the connecting block 44 displaces, it drives the limiting block 42 to move simultaneously, so that the clamping block 3 loses its limit, and it can be directly pulled out for disassembly.
[0037] The stable structure 2 includes a connecting plate 21, which is arranged at both ends inside the connecting piece 1. Pipe bodies 25 are arranged at the tops of the connecting plates 21, and the tops of the pipe bodies 25 are connected to the connecting piece 1. Large discs 22 are arranged on both sides at the bottom of the stable structure 2, and a sliding structure is formed between the large discs 22 and the connecting plates 21. Medium discs 23 are arranged on both sides at the bottom of the large discs 22, and a sliding structure is formed between the medium discs 23 and the large discs 22. Small discs 24 are arranged on both sides at the bottom of the medium discs 23, and a sliding structure is formed between the small discs 24 and the medium discs 23. Pistons 252 are arranged inside the pipe bodies 25, and first springs 251 are installed at the tops of the pistons 252. Inner cavities 254 are arranged on the inner walls of the pipe bodies 25, oil inlet holes 255 are arranged on both sides at the top of the inner cavities 254, and oil outlet holes 253 are arranged on both sides at the bottom of the inner cavities 254.
[0038] Referring to Figure 2 , Figure 7 and Figure 9 As shown, after the connecting piece 1 and the tower pole are fixed, due to the different diameters of the tubular tower poles, the elastic force of the first spring 251 pushes the connecting plate 21 to squeeze the side of the tower pole. Due to the shape and sliding fit between the large disc 22, the medium disc 23 and the small disc 24, the middle disc is squeezed, causing the whole to turn over. As the shape of the tower pole changes and it is squeezed and limited on its surface, the tower pole is fixed to the clamping block 33, preventing the connecting piece 1 from shifting and shaking on the tower pole. At the same time, when there is shaking or vibration, the piston 252 moves inward. There is hydraulic oil inside the pipe body 25. When the piston 252 moves inward, the internal hydraulic oil enters the inner cavity 254 through the oil inlet hole 255 and then reaches the bottom of the piston 252 through the oil outlet hole 253. When the first spring 251 pushes the piston 252 to reset, the hydraulic oil passes through the oil outlet hole 253, the inner cavity 254, and the oil inlet hole 255 and returns to the top of the piston 252 again. Since the number of oil outlet holes 253 is small, the oil return speed is reduced, so that the piston 252 resets slowly, achieving the effect of shock absorption and buffering.
[0039] Screws 31 are installed at both ends of the clamping block 3. The anti - detachment structure 5 includes first ratchets 51, which are installed at both ends on one side of the clamping block 3. Second ratchets 53 are arranged outside the screws 31 on one side of the first ratchets 51. Blocks 52 are arranged at the tops of the first ratchets 51. A clamping structure is formed between the first ratchets 51 and the second ratchets 53. A movable ring 514 is arranged on one side of the first ratchet 51, and a fourth spring 513 is sleeved outside the movable ring 514. Connecting shafts 512 are arranged at the corners on one side of the first ratchet 51, and connecting holes 511 are arranged on the side walls of the clamping block 3 outside the connecting shafts 512.
[0040] Referring to Figure 5 , Figure 8 and Figure 10As shown in the figure, pass the cable horizontally through between the clamping block 3 and the fixing block 32, then insert the first ratchet 51 so that the connecting shaft 512 enters the inside of the connecting hole 511. Then insert the abutting block 52 between the first ratchet 51 and the clamping block 3, and rotate the screw 31 to lock it. Due to the ratchet arrangement between the second ratchet 53 and the first ratchet 51, when the screw 31 is rotated and locked, the ratchets can slip to achieve rotation. As the screw 31 rotates, it drives the continuous locking and fixing between the clamping block 3 and the fixing block 32, realizing the fixed clamping of the cable. And the ratchet arrangement between the second ratchet 53 and the first ratchet 51 makes the screw 31 unable to reverse. When rotating in the reverse direction, the fourth spring 513 pushes the first ratchet 51 to engage with the second ratchet 53, making it unable to rotate, thereby avoiding loosening. When it is necessary to loosen the screw 31, push the abutting block 52 out to one side. After taking out the abutting block 52, press the first ratchet 51 towards the clamping block 3 to make the ratchets move away from each other, and then rotate the screw 31 in the reverse direction for disassembly.
[0041] An installation method of a cable anti-loosening component for a transmission and transformation project iron tower includes the following steps:
[0042] S1. First, fix the connecting piece 1 to the tower pole. The connecting piece 1 is clamped outside the tower pole. Press the connecting piece 1 to one side and then insert the clamping block 33 through the connecting piece 1 to the bracket 41. One side of the clamping block 33 pushes the limiting block 42 to move outward. When the protrusion on one side of the clamping block 33 is pushed away from the limiting block 42, the limiting block 42 is pushed to reset under the tension of the second spring 43 and is clamped and fixed with the clamping block 33.
[0043] S2. After the connecting piece 1 and the tower pole are fixed, due to the different diameters of the tower poles, under the elastic action of the first spring 251, the connecting plate 21 is pushed to squeeze one side of the tower pole. Due to the shape and sliding fit between the large disc 22, the middle disc 23 and the small disc 24, when being squeezed, it can be clamped along with the change of the outer shape of the tower pole, fixing the tower pole and the clamping block 33, and avoiding the phenomenon of the connecting piece 1 shifting and shaking on the tower pole.
[0044] S3. Then pass the cable through between the clamping block 3 and the fixing block 32, and then rotate the screw 31 to lock it, continuously locking and fixing between the clamping block 3 and the fixing block 32 to realize the fixed clamping of the cable. And under the action of the second ratchet 53 and the first ratchet 51, the screw 31 cannot reverse, thereby avoiding loosening and strengthening the firmness.
[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
