Description

Technical Field

[0001] The utility model relates to the technical field of optical cable construction, and particularly relates to an optical cable hook. Background Art

[0002] During the process of erecting optical cables in rural areas, optical cable hooks are needed to connect the optical cables with the messenger wire (galvanized steel strand). The function of the optical cable hook is to protect the optical cable and prevent the internal glass fiber core from being strained by long-distance suspension of the optical cable. As shown in the figure of the erected optical cable Figure 1 The specific construction sequence is usually to first erect the pole 01, drive the guy wire, lay the messenger wire 02, then tighten the messenger wire, and finally lay the optical cable 03 and install the optical cable hooks 04. To ensure the construction quality of the optical cable, the installation spacing of the optical cable hooks is generally required to be 45 cm, and about 2,200 optical cable hooks need to be installed per kilometer of pole line on average. During construction, it is required that the construction workers climb the pole to work, fasten the safety rope, work suspended on the messenger wire, and install the optical cable hooks one by one to hang the optical cable on the messenger wire.

[0003] Traditional optical cable hooks are as shown in Figure 2 The main models used are 25#, 35#, and 55#, and the number of optical cables that can be carried is 2 - 3, 3 - 4, and 4 - 6 respectively. The specific carrying quantity mainly depends on the thickness of the optical cable (the thicknesses of various types of optical cables are different). With the development of the communication services of each operator, the number of optical cables has increased sharply. Therefore, there is a situation where the optical cable hooks cannot carry a large number of optical cables, resulting in messy hanging of optical cables in the fields and villages, which not only affects the beauty of the rural environment but also affects agricultural production. It is very easy for mechanical farming to break the optical cable, and at the same time, it also brings great maintenance pressure to the operator.

[0004] When it is necessary to repeat laying the cable in different engineering batches, the construction workers need to first remove the original optical cable hooks, put the new optical cable in, and then install the optical cable hooks again. The whole process is difficult, time-consuming, and there is serious idling of workers. When the messenger wire is severely rusted, the construction workers climbing the pole for operation will also affect personal safety. The more original optical cables there are, the more difficult it is to add new optical cables. When the number of optical cables exceeds the load-bearing limit of the hooks, only aluminum core wires can be used to bundle the optical cables. Once the bundling starts, the optical cable and the messenger wire will be wrapped around each other, and the construction workers can no longer work suspended on the pole. They can only use a ladder or bundle the cables mechanically on the ground. Working on the pole will damage the fiber core of the optical cable; using a ladder is also very difficult. First, after the messenger wire is wrapped around, its rusting and aging are accelerated, and the construction workers cannot directly observe and judge the safety level, so the safety rope is no longer safe; second, the construction workers repeatedly climb up and down the ladder, and only 3 hooks can be installed each time, which exacerbates the idling of working hours. Mechanical bundling has two problems. One is that the bundling is unstable and the optical cable is easy to loosen and fall; the other is that the battery capacity of the operating equipment is limited, which restricts the daily construction workload.

[0035] Please refer to Figures 3 to 4 , a fiber optic cable hook provided in the embodiments of the present application includes a hook belly 1 and hook heads 2. The hook belly 1 is formed with a fiber optic cable bearing area 11 by bending a steel wire. The hook heads 2 are respectively arranged at both ends of the hook belly 1. The hook heads 2 are provided with hook noses 21 and hook ears 22. The hook noses 21 are used for hanging on a suspension wire during installation, and the hook ears 22 are used to connect with an external tool to achieve the hanging or separation of the hook noses 21 from the suspension wire.

[0036] In this embodiment, the hook belly 1 is roughly bent into a U shape by using a steel wire. The inner side of the steel wire forms the fiber optic cable bearing area 11. When in use, the fiber optic cable is inserted into the fiber optic cable bearing area 11. Both ends of the hook belly 1 are provided with hook heads 2. By hanging the hook noses 21 on the two hook heads 2 on the suspension wire, the fiber optic cable is hung on the suspension wire. Since the hook ears 22 are provided on the hook heads 2, when it is necessary to install or remove the fiber optic cable hook, by connecting an external tool to the hook ears 22, the hanging or separation of the hook noses 21 from the suspension wire can be achieved. Therefore, this fiber optic cable hook can support construction workers to operate on the ground, avoiding high-altitude operations such as personnel suspension and ladder erection, not only reducing the construction risk, but also improving the construction efficiency, and at the same time, it can carry more fiber optic cables.

[0037] According to some embodiments of the present application, an optical cable gasket 3 is provided on the hook belly 1, and the optical cable gasket 3 is located at the bottom of the optical cable bearing area 11. By providing the optical cable gasket 3 at the bottom of the optical cable bearing area 11 of the hook belly 1, when installed, the optical cable is supported on the optical cable gasket 3. Since the size of the optical cable gasket 3 is larger than the wire specification, the supporting contact area with the optical cable can be increased, thereby achieving a better protection effect on the optical cable and avoiding damage to the optical fiber core of the optical cable.

[0038] According to some embodiments of the present application, the optical cable gasket 3 is snap-connected to the hook belly 1. By adopting the above connection method, after the hook belly 1 is bent and wound into shape, the optical cable gasket 3 can be snap-connected to the bottom of the wire of the hook belly 1. In this way, the optical cable gasket 3 and the hook belly 1 can be manufactured separately, thus facilitating the production of the entire optical cable hook.

[0039] Specifically, with reference to the installation state of the optical cable hook, the lower side of the optical cable gasket 3 contacts the wire of the hook belly 1 to form a snap connection. For example, a plurality of card slots adapted to the wire specification are provided on the lower side of the optical cable gasket 3. During production and assembly, the wire is pressed into the card slots on the lower side of the optical cable gasket 3, and the optical cable gasket 3 is fixed to the bottom of the hook belly 1 through the interference fit between the wire and the card slots.

[0040] According to some embodiments of the present application, the optical cable gasket 3 has a bending arc adapted to the bottom of the optical cable bearing area 11. Since the hook belly 1 is roughly bent into a U shape by the wire, the wire at the bottom of the hook belly 1 (i.e., the bottom of the optical cable bearing area 11) has a certain bending arc. Therefore, after the optical cable gasket 3 is designed with a corresponding bending arc, the lower side of the optical cable gasket 3 can better adapt to the shape of the wire during the assembly of the optical cable gasket 3.

[0041] According to some embodiments of the present application, the optical cable gasket 3 is made of a rigid metal material or a non-metal material. According to the use requirements, the optical cable gasket 3 plays a supporting role for the optical cable placed in the hook belly 1. Therefore, it is required that the material of the optical cable gasket 3 has a certain rigidity so that it can maintain a good shape and achieve the installation snap connection with the wire.

[0042] According to some embodiments of the present application, the optical cable gasket 3 is an aluminum sheet or a plastic sheet. Using aluminum or plastic can make the optical cable gasket 3 meet the support for the optical cable, and at the same time make the optical cable gasket 3 have a lower weight and cost. Of course, it can be understood that the optical cable gasket 3 can also be made of other feasible materials.

[0043] According to some embodiments of the present application, the two hook heads 2 are arranged in mirror symmetry, and the hook nose 21 is located inside the hook belly 1, and the hook ear 22 is located outside the hook belly 1. With the above technical solution, during installation, one hook nose 21 is hung on the suspension line from one side of the axis of the suspension line, and the other hook nose 21 is hung on the suspension line from the other side of the axis of the suspension line, so that the optical cable hook can be better hung on the suspension line. At the same time, since the two hook ears 22 are located outside the hook belly 1, it is beneficial for construction workers to operate on the ground. By using an insulating rod with a steel fork and inserting it into the hook ear 22, the optical cable hook can be installed and removed.

[0044] According to some embodiments of the present application, the hook nose 21 has a U-shaped hook groove, the opening of the hook groove faces the bottom of the optical cable bearing area 11, and the width of the hook groove is adapted to the suspension line. With the above technical solution, during installation, the U-shaped hook groove on the hook nose 21 is connected to the suspension line, that is, the suspension line is to be caught in the U-shaped hook groove, and a clamping force can be applied to the suspension line through the deformation of the hook nose 21, so that the optical cable hook can be stably hung on the suspension line.

[0045] According to some embodiments of the present application, the two hook heads 2 and the hook belly 1 are integrally formed by continuously bending a steel wire. With such a setting, the integral winding strengthens the load-bearing capacity of the hook nose 21, increases the number of optical cables carried by the hook, and is convenient for production and manufacturing. Specifically, the end of the steel wire of the hook belly 1 forms a double-row steel wire after being bent for a section, the head of the double-row steel wire is bent into a U shape to form the hook nose 21, and the end of the steel wire is bent back to the double-row steel wire and spirally wound on the double-row steel wire for a section and then bent into a V shape to form the hook ear 22. Since the hook nose 21 is formed by bending a double-row steel wire, stress deformation caused by the hook nose 21 bearing a load can be avoided.

[0046] According to some embodiments of the present application, the steel wire is carbon steel wire or galvanized stainless steel wire. By using the above two steel wire materials, the production cost can be saved. At the same time, since the above steel wire materials have higher hardness, stress deformation of the hook nose 21 caused by the optical cable hook carrying the optical cable for a long time can be prevented. The diameter of the steel wire can be 3.4 mm or 3.6 mm.

[0047] The above specific embodiments have further elaborated on the purpose, technical solution and beneficial effects of the present invention. It should be understood that the above is only the specific embodiment of the present invention and is not used to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
