Description

Technical Field

[0001] This utility model relates to the field of optical cable laying technology, specifically to an optical cable laying traction device. Background Technology

[0002] Optical cable laying traction devices are key equipment in optical cable laying construction, widely used in line engineering construction in fields such as communication networks and broadcasting. Their main function is to provide stable and controllable traction force in different laying scenarios, such as overhead, duct, or direct burial, smoothly and safely pulling the optical cable from the laying reel into the pre-set duct or cable tray. A typical traction device usually consists of core components such as the traction machine body, tension control system, guide wheel assembly, and cable take-up and lay-down mechanism. Its performance directly affects construction efficiency and the quality of optical cable laying. In current optical cable duct laying operations, especially when using existing pre-buried ducts (such as silicon core tubes) for cable threading, complex construction environments and well locations influenced by terrain, often result in deep wells. When there is a small-angle bend at the traction end, the optical cable will inevitably come into direct contact and rub against hard parts such as the well wall edge or concrete pipe opening. This friction leads to two significant adverse consequences: First, it greatly increases the resistance and friction during the traction process. This not only requires the traction machine to output greater power, increasing energy consumption, but may also cause the traction force to exceed the rated tension of the optical cable, posing a risk of tearing or even breaking the optical fiber. Second, and most critically, this intense friction severely wears down the outer sheath and even the armor layer of the optical cable. This significantly reduces the mechanical strength and lifespan of the optical cable, creating long-term operational safety hazards, and may even lead to a decline in signal transmission quality or communication interruption. Therefore, an optical cable laying traction device is designed to solve the above problems. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a fiber optic cable laying and pulling device, comprising: a fiber optic cable pulling machine body 1, an extension frame 2 rotatably connected to the lower end of the cable inlet of the fiber optic cable pulling machine body 1, two take-up boxes 3 fixedly connected to the end of the extension frame 2, a guide wheel 4 rotatably connected between the two take-up boxes 3, a take-up rod 5 rotatably connected inside the take-up box 3, one end of the take-up rod 5 extending to the outside of the take-up box 3 and fixedly connected to a handle, an adjustment cable 6 wound around the outside of the take-up rod 5, a hollow barrier box 7 with open ends provided on the right side of the extension frame 2, a plurality of fiber optic cable outlet guide wheels 8 rotatably connected in an array inside the barrier box 7, and the ends of the two adjustment cables 6 fixedly connected to the upper and lower ends of the barrier box 7 respectively.

[0024] In use, place the main body 1 of the optical cable traction machine at the outlet position and place the end of the extension frame 2 at the edge of the well opening. The barrier box 7 is fitted on the outside of the optical cable. One end of the optical cable is inserted into the interior of the main body 1 of the optical cable traction machine. At this time, do not tighten the optical cable. Let the barrier box 7 slide down along the path of the optical cable. Rotate the handle to release the adjustment cable 6 on the outside of the take-up rod 5 until it falls to the junction of the pipe and the well opening. Stop rotating the handle. Then start the main body 1 of the optical cable traction machine. The optical cable slowly retracts. As the optical cable retracts, adjust the position of the barrier box 7 in real time by rotating the handle until the optical cable is tightened. The upper end of the barrier box 7 will be pushed against the upper end of the junction of the pipe and the well opening. At this time, pull the optical cable. When the optical cable is pulled out of the pipe, it will not contact the concrete at the corner of the pipe end, but will pass through the interior of the barrier box 7. The internal optical cable outlet guide wheel 8 will reduce friction, and the smooth surface will reduce the damage caused by friction. Afterwards, the optical cable will rise along the well opening and pass through the guide wheel 4 at the upper corner to prevent friction.

[0025] like Figure 1-4As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the extension frame 2 has slots 21 on both the front and rear sides of the right end, and the upper end of the cable inlet of the optical cable traction machine body 1 is fixedly connected with a buckle 22.

[0026] Analysis of the above structure shows that after the optical cable is installed, the extension frame 2 is pushed upwards, and the buckle 22 is inserted into the slot 21, so that the extension frame 2 is fixed.

[0027] like Figure 1-4 As shown, this utility model embodiment provides an implementation method in which a rubber pad 23 is attached to the upper end of the barrier box 7 based on the above implementation method.

[0028] Analysis of the above structure shows that the rubber pad 23 attached to the barrier box 7 can increase the friction between the barrier box 7 and the concrete inside the pipe wall, while preventing the barrier box 7 from directly contacting the concrete. After excessive wear, the rubber pad 23 can be replaced.

[0029] like Figure 1-4 As shown, this utility model embodiment provides an implementation method in which the upper surface of the rubber pad 23 is arc-shaped.

[0030] Analysis of the above structure shows that the upper surface of the rubber gasket 23 is arc-shaped, which can be replaced and attached to the pipe wall to increase the contact surface and thus improve the friction.

[0031] like Figure 1-4 As shown in the figure, this utility model embodiment provides an implementation method in which the upper right side of the barrier box 7 is arc-shaped.

[0032] Analysis of the above structure shows that the upper right side of the barrier box 7 is arc-shaped, which allows the right side of the barrier box 7 to act as a guide when it is placed in.

[0033] like Figure 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, both the barrier box 7 and the optical cable outlet guide wheel 8 are made of stainless steel.

[0034] Analysis of the above structure shows that both the barrier box 7 and the optical cable outlet guide wheel 8 are made of stainless steel, which reduces the probability of rust and extends the service life.

[0035] like Figure 1-4 As shown, this utility model embodiment provides an implementation method in which the weight of the lower end of the barrier box 7 is greater than the weight of the upper end.

[0036] Analysis of the above structure shows that the weight of the lower end of the barrier box 7 is greater than the weight of the upper end, so that the center of gravity of the barrier box 7 is lower when it is put down, reducing the risk of tipping over.
