Abstract

The invention discloses a central tube type ADSS (All-Dielectric Self-Supporting) optical fiber cable take-up machine which comprises a cable tray and a motor, wherein the output end of the motor is connected with a positioning cylinder, the positioning cylinder is internally provided with an air cylinder, the upper end surface of the positioning cylinder is fixedly connected with a rotating cylinder communicated with the interior of the positioning cylinder, and the output end of the air cylinder is provided with multiple annular teeth; one end of a guide rod is provided with fan-shaped teeth matched with the annular teeth, the guide rod is internally provided with a cavity, and the tail end of the top rod is connected with the inner wall of the cavity by virtue of a spring; the inner wall, which is close to one side of a guide ring, of the cavity is provided with an annular bulge, and the movable end of the top rod is fixedly provided with a limiting block which is matched with the annular bulge; the guide ring can limit an optical fiber cable, the optical fiber cable is prevented from bouncing during a moving process; meanwhile, by virtue of the up-and-down movement of the guide rod, the swing range of the optical fiber cable can be buffered, after the optical fiber cable enters into the cable tray, a relatively stable state of the cable tray is ensured, distribution of each layer of the optical fiber cable on the cable tray is more uniform, and the two adjacent loops of optical fiber cable can be closely attached together.

Description

technical field [0001] The invention relates to the field of optical cable laying, in particular to a central tube type ADSS optical cable take-up machine. Background technique [0002] In daily life, optical fibers are used for long-distance information transmission because the loss of light in optical fibers is much lower than that of electricity in wires. Most optical fibers must be covered by several layers of protective structures before use. The coated cable is called an optical cable. The protective layer and insulating layer on the outer layer of the optical fiber can prevent the surrounding environment from harming the optical fiber, such as water, fire, electric shock, etc. . [0003] During the long-distance laying of optical cables, due to the influence of various factors, some of the pulled out optical cables need to be recycled. In the prior art, due to the distance factor, the optical cables are usually manually rotated when the cable is pulled to achieve the...

Problems solved by technology

[0003] During the long-distance laying of optical cables, due to the influence of various factors, some of the pulled out optical cables need to be recycled. In the prior art, due to the distance factor, the optical cables are usually manually rotated when the cable is pulled to achieve the optical cable on the cable reel. Layers are stacked on top of each other, and the strength of the cable will increase with the increase of the distance when it is recovered, so some parts of the optical cable may be partially damaged due to the concentration of stress. The surge phenomenon occurs at the outlet of the reel, which makes the middle part of the optical cable and the end of the optical cable circle, that is, it is very likely to cause the bending radius of the optical cable to be less than 15 to 20 times its outer diameter, which increases the possibility of damage to the optical fiber. , at the same time, the work intensity of manually rotating the cable drum is high, and the work efficiency of the workers is low
