Description

Technical Field

[0001] The invention relates to the field of aerial optical cable hooks, in particular to an aerial optical cable hook which is easy to operate. Background Art

[0002] With the widespread use of optical cables in communications transmission, overhead installation has become a crucial method for traversing complex terrain. However, traditional fixing methods (such as simple tying and wire wrapping) present numerous problems: overly tight tying can easily damage the cable sheath, while too loose tying can cause the cable to vibrate, rub, or fall off, and it is difficult to adapt to cables of varying diameters. While wire fixing offers high strength, it is susceptible to rust and breakage due to long-term environmental erosion, and the rigid contact can also exacerbate cable wear. To address these issues, cable hooks have emerged, capable of stably suspending optical cables from load-bearing cables (steel strands), adapting to cable size, and providing basic protection. These hooks have become specialized accessories that balance the need for reliable fixing and cable protection.

[0003] The Chinese patent publication number CN2879223Y discloses a "portable communication hook device", which consists of a clamping head and a connecting rod. Its characteristics are that the clamping head has a square cross-section structure, a "V"-shaped clamping groove is provided on the upper part, and the hook is placed in the "V"-shaped clamping groove. The lower part of the clamping head is provided with a connecting clamping tray to connect the clamping head and the fixed connecting rod. The lower part of the fixed connecting rod is provided with a lock hole, which is matched with the lock pin of the next connecting rod. The upper end of each connecting rod is provided with a connecting rod plug and the lower end is provided with a connecting rod bolt hole. After the connecting rods are plugged in, the keyhole is fixed with screws to make a portable communication hook device.

[0004] Although this technical solution is convenient and quick to carry, install and disassemble, and its novel structure of the clamp head combined with the connecting rod only requires one person on the ground to operate and complete the hook addition of overhead optical and electrical cables, this device is the same as the traditional optical cable hook. The hooks used to hang on the load-bearing rope are all U-shaped and semi-closed. Therefore, after long-term suspension, the U-shaped hooks are very likely to become unhooked, causing the device to fall like the traditional optical cable hooks.

[0005] At the same time, because the installation length of the optical cable and the load-bearing rope is very long, the farther the distance between the optical cable and the load-bearing rope is from the communication base station, the greater the vertical distance between the optical cable and the load-bearing rope will be. After the installation of the device and the traditional optical cable hook, if the optical cable and the device or the traditional optical cable hook generate greater or lesser pressure, then the staff can only replace the device or the traditional optical cable hook with a different model to reinstall it, which greatly delays the fixed installation work between the optical cable and the load-bearing rope.

[0006] Therefore, an aerial optical cable hook which is easy to operate is proposed. Summary of the Invention

The outer side of each second sliding column is fixedly connected to a connecting arm, and the outer sides of the two connecting arms are jointly fixedly installed with an optical cable supporting block.

[0012] Furthermore, the second arc groove is slidably adapted to the side wall of the sliding arc plate, the hemispherical locking block is composed of a hemispherical block and a disc, and the radius of the hemispherical locking block disc is larger than the radius of the sliding residual ring, and the top of the sliding arc plate is fixedly connected to the rotating rod.

[0013] Furthermore, the radius of the third arc-shaped groove is adapted to the radius of the hemispherical block of the hemispherical locking block, and the third arc-shaped groove is located on the movement path of the hemispherical locking block.

Secondly, it can avoid the shaking and friction of the optical cable or even falling off caused by the looseness between the optical cable bearing block and the optical cable. It can also avoid the cracking of the outer sheath caused by excessive squeezing between the optical cable bearing block and the optical cable, thereby effectively avoiding the damage of the internal optical fiber of the optical cable caused by cracking of the outer sheath. At the same time, the pressure between the optical cable bearing block and the optical cable can be controlled by sliding the second sliding column, avoiding the situation that different models of hooks need to be replaced due to the distance between the optical cable and the optical cable bearing block being too large or too small, thereby saving the work process of repeatedly matching models during the installation of traditional hooks, and avoiding the situation that the optical cable and the optical cable bearing block have to be replaced as a whole after installation due to pressure problems, thereby making the fixation of the optical cable more convenient.

A handle 302 is fixedly installed on one end of the rotating rod 301 away from the center of the semi-arc shell 2. A fixed residual circular ring 303 is fixedly connected to the interior of the semi-arc shell 2. A first arc groove 304 is provided on the outer arc surface of the semi-arc shell 2, and a second arc groove 305 is provided on the outer arc surface of the fixed residual circular ring 303. Each semi-arc housing 2 is provided with a clamping fixing assembly 4, which includes two first fixing plates 401.

The adjustment assembly 5 includes a second fixing plate 501 . The second fixing plate 501 is fixedly connected to the side wall of the semi-arc housing 2 .

[0024] The hand-held rotating assembly 3 also includes a sliding residual circular ring 306, which is slidably connected to the inside of the fixed residual circular ring 303.

The end of the sliding residual circular ring 306 away from the sliding arc plate 307 is fixedly connected to a hemispherical locking block 308. The hemispherical locking block 308 is formed by the hemispherical block and the The hemispherical locking block 308 is composed of a circular disc, and the radius of the circular disc of the hemispherical locking block 308 is larger than the radius of the sliding residual circular ring 306.

[0025] The clamping fixing assembly 4 also includes four first sliding columns 402, the outer side of each first sliding column 402 is penetrated and slidably connected to the middle part of the first fixed plate 401, the outer side of each first sliding column 402 is penetrated and slidably connected to the semi-arc shell 2, and a spring 403 is fixedly connected to the side of each first fixed plate 401 away from the semi-arc shell 2. The outer side of each first sliding column 402 is sleeved with the spring 403, and the end of each spring 403 away from the first fixed plate 401 is fixedly connected to a circular plate 404. The side of 404 close to the first fixed plate 401 is fixedly connected to the first sliding column 402, and the end of each first sliding column 402 away from the circular plate 404 is fixedly connected to a tilting block 405. Every two tilting blocks 405 are located on the movement path of the hemispherical locking block 308. A plurality of rubber blocks 406 are arranged in a linear array on the inner arc surface of the semi-arc shell 2 close to the outer side of the load-bearing cable 1. The multiple rubber blocks 406 provide additional friction with the outer side of the stranded wire of the load-bearing cable 1, thereby helping the semi-arc shell 2 to be fixed on the outer side of the load-bearing cable 1.

[0026] The adjustment component 5 also includes two fixed rails 502, each fixed rail 502 is fixedly connected to the side of the second fixed plate 501 away from the semi-arc shell 2, and a plurality of adjustment holes 503 are opened in a linear array on each fixed rail 502, and the interior of each fixed rail 502 is slidingly connected to a second sliding column 504, and each second sliding column 504 is slidingly connected to a pin 505, and the outer side of each pin 505 is slidingly adapted to the adjustment hole 503, and the outer side of each second sliding column 504 is fixedly connected to a connecting arm 506, and the outer sides of the two connecting arms 506 are jointly fixedly installed with an optical cable supporting block 507, the material of the connecting arm 506 is set to hard plastic or galvanized steel wire, and the connecting arm 506 is set to an arc-shaped thin strip, and the material of the optical cable supporting block 507 is consistent with the material of the connecting arm 506, and the optical cable supporting block 507 is in the shape of a U-shaped groove, and the curvature of the optical cable supporting block 507 matches the common optical cable diameter, such as adapting to optical cables with a diameter of eight millimeters, a diameter of ten millimeters, and other specifications.

[0027] The above implementation works as follows: The initialization steps are as follows: The staff selects an appropriate optical cable supporting block 507 according to the radius of the optical cable to be supported, and uses a ladder to reach the vicinity of the supporting cable 1 while ensuring safety. The staff then holds a semi-arc shell 2 and fits the rubber block 406 in the inner arc surface of the semi-arc shell 2 onto the outer side of the supporting cable 1.

[0028] The steps for running the job are as follows: The working steps of the hand-held rotating component 3 are as follows: When multiple rubber blocks 406 are attached to the outside of the load-bearing cable 1, the staff member holds the handle 302 and starts to rotate it, so that the handle 302 starts to move along the outer arc surface of the semi-arc shell 2. Therefore, the handle 302 drives the rotating rod 301 to start rotating with the connection between the rotating rod 301 and the semi-arc shell 2 as the axis. At the same time, the end of the rotating rod 301 away from the connection between the semi-arc shell 2 and the rotating rod 301 drives the sliding arc plate 307 to move synchronously. Therefore, the sliding arc plate 307 slides inside the second arc groove 305 and shows an arc motion. At the same time, the sliding arc plate 307 drives the sliding incomplete circular ring 306 to slide inside the fixed incomplete circular ring 303. Therefore, the sliding incomplete circular ring 306 drives the hemispherical locking block 308 to move toward the direction close to the circular hole 310.

[0029] The working steps of the clamping and fixing component 4 are as follows: As described above, as the hemispherical locking block 308 moves toward the direction approaching the circular hole 310, when the disc of the hemispherical locking block 308 enters the interior of the circular hole 310, the continuous movement of the hemispherical locking block 308 causes the semicircular block of the hemispherical locking block 308 to first resist and push the tilting block 405 to move away from the center of the third arc groove 309. Similarly, the tilting block 405 drives the first sliding post 402 to slide inside the semi-arc housing 2 and the first fixed plate 401 in the direction away from the center of the third arc groove 309. Therefore, the first sliding post 402 drives the circular plate 404 to move in the direction away from the first fixed plate 401. At the same time, the circular plate 404 stretches the spring 403. When the disc of the hemispherical locking block 308 passes the tilting block 405, the spring 403 is at the maximum elastic stretching point. At the same time, as the hemispherical locking block 308 continues to move, when the hemispherical locking block 308 When the semicircular block enters the interior of the third arc groove 309, the disc of the hemispherical locking block 308 no longer conflicts with the tilting block 405. At this moment, the sliding residual ring 306 is located between the two tilting blocks 405. Therefore, the spring 403 pulls the circular plate 404 toward the first fixed plate 401 through the elastic contraction force, and the circular plate 404 pushes the first sliding column 402 to move toward the direction of the sliding residual ring 306, so that the first sliding column 402 drives the tilting block 405 to move toward the direction of the sliding residual ring 306. Therefore, the opposite surfaces of the two tilting blocks 405 conflict with the outer sides of the sliding residual ring 306. At the same time, the tops of the two tilting blocks 405 conflict with the bottom of the disc of the hemispherical locking block 308, so that the two tilting blocks 405 are clamped to the hemispherical locking block 308. Therefore, the sliding residual ring 306 and the semi-arc shell 2 form a full circle and fix the load-bearing cable 1 therein.

[0030] The working steps of the hand-held rotating component 3 and the clamping fixing component 4 are as follows: When one of the semi-arc shells 2 completes the above working steps, the staff continues to hold the other semi-arc shell 2 to repeat the above working steps, and the staff adjusts the optical cable supporting block 507 between the two semi-arc shells 2 to the bottom of the optical cable, so that the upper surface of the optical cable supporting block 507 supports the optical cable.

[0031] At the same time, when it is necessary to remove the two semi-arc housings 2, the staff only needs to pull the circular plate 404 to make the spring 403 start to stretch, and at the same time return the handle 302 to the initial position.

[0032] The hand-held rotating component 3 and the card-connected fixing component 4 are arranged to form a full circle through the semi-arc shell 2 and the sliding residual circle ring 306 to fix the load-bearing cable 1. At the same time, the fit between the rubber block 406 and the load-bearing cable 1 also provides additional friction to assist in its fixation, thereby avoiding the semi-closed fixation of the traditional hook in a U shape, which causes it to become unhooked after long-term hanging. At the same time, the staff only needs to hold the handle 302 to move it, without the need for complicated operating steps. At the same time, the fully closed fixation is relative to the semi-closed fixation. First, it can ensure the long-term support of the optical cable, and secondly, it avoids the work steps of frequent replacement of traditional hooks.

[0033] The working steps of the adjustment component 5 are as follows: Because the installation length of the optical cable and the load-bearing rope 1 is very long, the farther the distance between the optical cable and the load-bearing rope 1 is from the communication base station, the greater the distance between the optical cable and the load-bearing rope 1 will be. At the same time, the outer side of the optical cable should not be subjected to excessive external force, and it must be subjected to the bearing capacity of the optical cable bearing block 507. When the optical cable bearing block 507 contacts the optical cable, because the optical cable is provided with an outer sheath, and the outer sheath of the optical cable is composed of polyethylene, the staff shakes the optical cable slightly by hand. If the optical cable and the optical cable bearing block 507 do not have effective friction, then at this time, therefore, when the distance between the optical cable and the load-bearing rope 1 is too large, the bearing capacity of the optical cable bearing block 507 for the optical cable is too small. If the optical cable and the optical cable bearing block 507 have effective friction, and there is no obvious indentation between the outer sheath of the optical cable and the optical cable bearing block 507, then at this time, the optical cable bearing block The bearing capacity of 507 for the optical cable is just right. If the outer sheath of the optical cable is obviously deformed after contacting the optical cable bearing block 507, it means that the bearing capacity of the optical cable bearing block 507 for the optical cable is too large. Then, when the bearing capacity of the optical cable bearing block 507 for the optical cable is too small, the staff first holds the pin 505 with one hand and pulls the pin 505 out of the inside of the second sliding column 504, and the pin 505 is separated from the inside of the adjustment hole 503, so that the staff holds the second sliding column 504 with the other hand and vertically upward along the inside of the fixed track 502. At the same time, because there are multiple adjustment holes 503, the staff judges the bearing capacity of the optical cable bearing block 507 for the optical cable based on the above. Therefore, when the second sliding column 504 slides to the appropriate position, the staff will pass the pin 505 through the adjustment hole 503 and the second sliding column 504 again.

[0034] Compared with the traditional simple hook, the setting of the adjustment component 5 can firstly adjust the pressure between the optical cable bearing block 507 and the optical cable, avoiding the situation that the traditional hook is fixed in size and the staff needs to replace the hook with other models once the outer sheath of the optical cable is deformed. Secondly, it can avoid the optical cable shaking and friction, or even falling off, caused by the looseness between the optical cable bearing block 507 and the optical cable. It can also avoid the situation that the outer sheath is squeezed too tightly between the optical cable bearing block 507 and the optical cable and causes cracking, thereby effectively avoiding the situation that the internal optical fiber of the optical cable is damaged due to cracking of the outer sheath. At the same time, the pressure between the optical cable bearing block 507 and the optical cable can be controlled by sliding the second sliding column 504, avoiding the situation that different models of hooks need to be replaced due to the distance between the optical cable and the optical cable bearing block 507 being too large or too small, thereby saving the work process of repeatedly matching models during the installation of traditional hooks, and avoiding the situation that the optical cable and the optical cable bearing block 507 have pressure problems after installation and need to be replaced as a whole, thereby making the fixing of the optical cable more convenient.
