Description

Technical Field

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

[0002] Optical fiber cables are cables used to transmit telephone, telegram, fax documents, television and radio programs, data and other electrical signals. They are made of one or more pairs of insulated conductors twisted together. Optical fiber cables have advantages such as large communication capacity, high transmission stability, good confidentiality and less susceptibility to natural conditions and external interference.

[0003] Most existing optical cables are laid using underground ducts. This involves first pre-burying underground ducts, then threading the optical cable through the duct using a traction rope. During the cable pulling process, the traction rope is usually tied to the optical cable. However, because the optical cable has a circular cross-section and a certain degree of rigidity, this connection method can easily cause the communication cable to detach during the pulling process. Moreover, current traction devices are all integrated and difficult to disassemble, making the process labor-intensive and time-consuming.

[0004] Therefore, we propose a traction device for optical cable manufacturing to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a traction device for optical cable manufacturing, so as to solve the problems mentioned in the background art. Because the cross-section of the optical cable is circular and has a certain degree of rigidity, the optical cable is easily detached during the traction process when using this connection method. Moreover, the current traction devices are all integrated and difficult to disassemble, which makes it very labor-intensive and time-consuming.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a workbench and a first fixed plate fixedly installed on the workbench, a second fixed plate fixedly installed on the workbench, a winding assembly for winding the cable provided on the side wall of the first fixed plate, the winding assembly including a motor fixedly installed on the side wall of the first fixed plate, a rotating shaft fixedly installed at the output end of the motor, the rotating shaft being rotatably connected to the second fixed plate, a winding drum fixedly installed on the axial side wall of the rotating shaft, a traction rope wound on the axial side wall of the winding drum, and a traction assembly for dragging the optical cable provided at one end of the traction rope (24).

[0007] Preferably, the traction assembly includes an operating block fixedly installed at one end of a traction rope, a tension rope fixedly installed on the side wall of the operating block, a traction body fixedly connected to one end of the tension rope, a chamber formed inside the traction body, a rope-passing hole formed on the axial side wall of the traction body, a support plate fixedly installed inside the chamber, two limiting plates fixedly installed on the support plate, a rotating shaft rotatably mounted between the two limiting plates, a pressing plate fixedly installed on the axial side wall of the rotating shaft, and a connecting rope provided between the operating block and the pressing plate, the connecting rope passing through the rope-passing hole.

[0008] Preferably, a semi-circular clamp is fixedly installed in the cavity, a sliding groove is provided on the inner wall of the semi-circular clamp, a rubber clamp is slidably installed on the inner wall of the semi-circular clamp, a number of steel balls are rotatably connected to the end of the traction body, an optical cable is squeezed and connected to the end of the traction body, and a quick-release component for easy disassembly of the clamp is provided on the axial side wall of the semi-circular clamp.

[0009] Preferably, the quick-release assembly includes a locking block one fixedly installed on the axial sidewall of a semi-arc clamp one. The semi-arc clamp one and the semi-arc clamp two are connected by screws. The locking block two is fixedly installed on the axial sidewall of the semi-arc clamp two. The screw passes through the locking block one and the locking block two. The end of the screw is threadedly connected to a nut. A spring is provided between the nut and the locking block two. A disassembly port is opened on the axial sidewall of the traction body. A cover plate is snapped onto the axial sidewall of the traction body.

[0010] Preferably, the inner diameter of the extrusion plate is smaller than the inner diameter of the rubber clamp.

[0011] Preferably, the displacement generated by the spring is less than the difference between the outer diameter of the rubber clamp and the outer diameter of the clamp.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Insert the optical cable into the traction body and start the motor. Under the action of the motor, rotating shaft, and winding drum, the winding drum pulls the traction rope to move towards the winding drum. With the cooperation of the traction rope, operating block, connecting rope, and tension rope, the connecting rope drives the extrusion plate to rotate through the rotating shaft. The other end of the extrusion plate extrudes the rubber clamp, causing the rubber clamp to enter the semi-circular clamp. Because the rubber clamp has strong adsorption, it greatly strengthens the reinforcement of the optical cable and prevents the optical cable from falling off during the traction process. When the rubber clamp is fully inside the semi-circular clamp, the extrusion plate will also extrude and reinforce the optical cable, further increasing the reinforcement effect of the optical cable.

[0014] 2. The cover plate is connected to the traction body by a snap-fit. First, open the cover plate, unscrew the nut, take out the spring, and then remove the second semi-circular clamp. At this time, the rubber clamp will return to its original shape due to the release of force. Then take out the optical cable. The traction body can be reused. When pulling the optical cable in the pipeline, because there may be a bend in the pipeline, the steel balls around the traction body can make the traction body roll and move in the pipeline. This not only allows it to pass through the bend smoothly, but also speeds up the traction speed. Attached Figure Description

[0020] 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.

[0021] Example 1: Please refer to Figure 1 , Figure 2 and Figure 4The system includes a workbench 1 and a first fixed plate 12 fixedly mounted on the workbench 1. A second fixed plate 11 is fixedly mounted on the workbench 1. A winding assembly 2 for winding the cable is provided on the side wall of the first fixed plate 12. The winding assembly 2 includes a motor 21 fixedly mounted on the side wall of the first fixed plate 12. A rotating shaft 22 is fixedly mounted on the output end of the motor 21. The rotating shaft 22 is rotatably connected to the second fixed plate 11. A winding drum 23 is fixedly mounted on the axial side wall of the rotating shaft 22. A traction rope 24 is wound on the axial side wall of the winding drum 23. A traction assembly 3 for dragging the optical cable is provided at one end of the traction rope 24.

[0022] The traction assembly 3 includes an operating block 31 fixedly installed at one end of the traction rope 24. A tension rope 32 is fixedly installed on the side wall of the operating block 31. One end of the tension rope 32 is fixedly connected to a traction body 33. A chamber 35 is opened inside the traction body 33. A rope-passing hole 34 is opened on the axial side wall of the traction body 33. A support plate 37 is fixedly installed inside the chamber 35. Two limiting plates 38 are fixedly installed on the support plate 37. A rotating shaft 39 is rotatably installed between the two limiting plates 38. A compression plate 301 is fixedly installed on the axial side wall of the rotating shaft 39. The end of the compression plate 301 is made of rubber. A connecting rope 36 is provided between the operating block 31 and the compression plate 301. The connecting rope 36 passes through the rope-passing hole 34.

[0023] A semi-circular clamp 304 is fixedly installed inside the chamber 35. A sliding groove 305 is provided on the inner wall of the semi-circular clamp 304. A rubber clamp 302 is slidably installed on the inner wall of the semi-circular clamp 304. Several steel balls 306 are rotatably connected to the end of the traction body 33. An optical cable 5 is squeezed and connected to the end of the traction body 33. A quick-release component 4 for easy disassembly of the clamp is provided on the axial side wall of the semi-circular clamp 304.

[0024] The inner diameter of the extrusion plate 301 is smaller than that of the rubber clamp 302. When the connecting rope 36 is dragged, one end of the extrusion plate 301 moves toward the traction rope 24, and the displacement trajectory of the other end is arc-shaped. While extruding the rubber clamp 302, the optical cable 5 will not be extruded in the middle.

[0025] The displacement generated by the spring 44 is less than the difference between the outer diameter of the rubber clamp 302 and the outer diameter of the rubber clamp 302. The outer diameter of the rubber clamp 302 increases from small to large. The small outer diameter is equal to the diameter of the optical cable 5. When the rubber clamp 302 enters the semi-arc clamp 304, the rubber clamp 302 will squeeze the semi-arc clamp 304.

[0026] In this embodiment: the optical cable 5 is threaded into the traction body 33, the motor 21 is started, and the output end of the motor 21 drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the take-up drum 23 to rotate, pulling the traction rope 24 to move within the pipe. The traction rope 24 moves towards the take-up drum 23, and the traction rope 24 pulls the operating block 31 to move. Initially, the connecting rope 36 and the tension rope 32 are in a slack state. At this time, the operating block 31 pulls the connecting rope 36 and the tension rope 32 to move. The connecting rope 36 drives the extrusion plate 301 to rotate through the rotating shaft 39. The other end of the extrusion plate 301 is attached to the rubber clamp 3. 02. Extrusion is performed. Because the rubber clamp 302 is made of rubber and has a certain degree of elasticity, the rubber clamp 302 enters the semi-circular clamp 304 through the sliding groove 305. The semi-circular clamp 304 and the semi-circular clamp 303 are fixed by screws 42. Because the rubber clamp 302 has strong adsorption, it greatly strengthens the reinforcement of the optical cable 5 and prevents the optical cable 5 from falling off during the pulling process. When the rubber clamp 302 is fully inserted into the semi-circular clamp 304, the extrusion plate 301 will also extrude and reinforce the optical cable 5, further reducing the possibility of the optical cable 5 falling off.

[0027] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 3 and Figure 4 The quick-release assembly 4 includes a locking block 41 fixedly installed on the axial side wall of the semi-arc clamp 304. The semi-arc clamp 304 and the semi-arc clamp 303 are threadedly connected by a screw 42. A locking block 45 is fixedly installed on the axial side wall of the semi-arc clamp 303. The screw 42 passes through the locking block 41 and the locking block 45. The end of the screw 42 is threadedly connected to a nut 43. A spring 44 is provided between the nut 43 and the locking block 45. A disassembly port 47 is opened on the axial side wall of the traction body 33. A cover plate 46 is snapped onto the axial side wall of the traction body 33.

[0028] In this embodiment: the cover plate 46 is connected to the traction body 33 by a snap fastener. First, open the cover plate 46, unscrew the nut 43, take out the spring 44, and then remove the semi-arc clamp 303. At this time, the rubber clamp 302 will return to its original state due to the unloading of force. Then take out the optical cable 5. The traction body 33 can be reused. When pulling the optical cable 5 in the pipeline, because there may be a bend in the pipeline, the steel balls 306 around the traction body 33 can make the traction body 33 roll and move in the pipeline. This not only allows it to pass through the bend smoothly, but also speeds up the traction speed.
