Description

Technical Field

[0001] The utility model relates to the technical field of optical cable production, in particular to a yarn binding structure for improving the tensile resistance of an optical cable. Background Technique

[0002] In the optical wire and cable industry, there has always been a problem of indentations appearing after the completion of the sheath of the optical cable core. The vast majority of indentations are caused by excessive tension of the binding yarn in the cable stranding process, resulting in indentations on the optical cable core during sheathing. After retrieval, a patent with the Chinese patent publication number CN213085058U discloses a real-time binding yarn tension measuring device, which includes an aircraft, a brush probe, and a controller. At least two guide wheels and a pressure sensor are arranged on the aircraft. The pressure sensor is located between the two guide wheels. The binding yarn is wound around the two guide wheels and the pressure sensor. The pressure sensor is connected to the controller through the brush probe.

[0003] Although the above technical solution solves the problem that the real-time tension of the binding yarn cannot be measured in the existing optical cable stranding process, when in use, the tension sensor is connected to the controller through the brush probe, which is not only vulnerable but also increases the use cost and is inconvenient for maintenance, and can only detect the tension and cannot adjust the tension. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a yarn binding structure for improving the tensile resistance of an optical cable, which solves the problem that although the existing device can replace manual work to climb the iron tower for operation, when encountering the connection of the steel frame structure of the iron tower during the climbing process, obstacles will exist on both sides, which will prevent the device from continuing to move, thus reducing the practicability of the device mentioned in the background technique.

[0005] To achieve the above objectives, the utility model is realized through the following technical solutions: A yarn binding structure for improving the tensile resistance of an optical cable includes a base. The upper surface of the base is fixedly connected with a support plate. The outer surface of the support plate is rotatably connected through a central tube. A central disc is fixedly sleeved on the outer surface of the central tube. A yarn bobbin is rotatably connected to the outer surface of the central tube in a limited manner. A yarn is wound around the outer surface of the yarn bobbin. An optical cable line penetrates through the inside of the central tube. One end of the yarn is wound around the optical cable line. A tension detection and adjustment mechanism is installed between the outer surface of the central disc and the base.

[0006] Preferably, the tension detection and adjustment mechanism includes an electric push rod fixedly installed on the upper surface of the base. One end of the electric push rod is fixedly connected to a tensile force sensor. One side of the tensile force sensor is fixedly connected to a hollow side plate that is slidably connected to the upper surface of the base. A bearing is fixedly installed inside the hollow side plate. The inner ring of the bearing is fixedly connected to a connecting rod. One end of the connecting rod is fixedly connected to a rectangular frame. A first wire wheel that cooperates with the yarn is rotatably connected inside the rectangular frame, which can detect the tension of the yarn while tying the optical cable with yarn, and can be adjusted according to the actual required tension.

[0007] Preferably, the other end of the rectangular frame is fixedly connected to a rectangular rod. A rectangular tube is slidably sleeved on the outer surface of the rectangular rod. One end of the rectangular tube is fixedly connected to the outer surface of the central disk, which can drive the rectangular frame to rotate synchronously when the central disk rotates.

[0008] Preferably, a bracket is fixedly connected to the outer surface of the central disk. A second wire wheel that cooperates with the yarn is rotatably connected inside the bracket, which is convenient for guiding the yarn.

[0009] Preferably, a motor is fixedly installed on the upper surface of the base. The output shaft of the motor is fixedly connected to a first belt pulley. A second belt pulley is fixedly sleeved on the outer surface of the central tube. A synchronous belt is meshed between the first belt pulley and the second belt pulley, which is convenient for driving the yarn bobbin and the yarn to rotate around the optical cable.

[0010] The utility model provides a yarn tying structure for improving the tensile strength of an optical cable. It has the following beneficial effects:

[0011] In this yarn tying structure for improving the tensile strength of an optical cable, through the provided tension detection and adjustment mechanism, not only can the tension of the yarn be detected, but also the tensile force sensor is located above the base instead of being installed on the central disk. Therefore, it can be directly connected to an external controller through a wire, which is convenient for use, thus solving the problem that in the existing device, the tensile force sensor is connected to the controller through a brush probe, which is not only vulnerable but also increases the use cost and is inconvenient for maintenance. When the tensile force sensor detects abnormal tension, at this time, the electric push rod runs to drive the first wire wheel to move left and right, so that the yarn tension can be adjusted, the yarn tying effect of the optical cable can be improved, and the tensile capacity of the optical cable can be further improved, thus solving the problem that the existing device can only detect the tension but cannot adjust the tension.

Specific embodiments

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Embodiment 1:

[0018] As Figure 1 and Figure 2 shown, an optical cable tensile strength enhancing binding yarn structure includes a base 1. The upper surface of the base 1 is fixedly connected with a support plate 2. The outer surface of the support plate 2 is rotatably connected through the central tube 3. The outer surface of the central tube 3 is fixedly sleeved with a central disc 4. The outer surface of the central tube 3 is rotationally connected with a yarn bobbin 5 in a limited way. The outer surface of the yarn bobbin 5 is wound with a yarn 6. The inside of the central tube 3 is penetrated with an optical cable 7. One end of the yarn 6 is wound on the optical cable 7. A tension detection and adjustment mechanism 8 is installed between the outer surface of the central disc 4 and the base 1. The tension detection and adjustment mechanism 8 includes an electric push rod 81 fixedly installed on the upper surface of the base 1. One end of the electric push rod 81 is fixedly connected with a tension sensor 82. One side of the tension sensor 82 is fixedly connected with a hollow side plate 83 slidably connected with the upper surface of the base 1. The inside of the hollow side plate 83 is fixedly installed with a bearing 84 by embedding. The inner ring of the bearing 84 is fixedly connected with a connecting rod 85. One end of the connecting rod 85 is fixedly connected with a rectangular frame 86. The inside of the rectangular frame 86 is rotatably connected with a first wire wheel 87 that cooperates with the yarn 6. The other end of the rectangular frame 86 is fixedly connected with a rectangular rod 88. The outer surface of the rectangular rod 88 is slidably sleeved with a rectangular tube 89. One end of the rectangular tube 89 is fixedly connected with the outer surface of the central disc 4. The outer surface of the central disc 4 is fixedly connected with a bracket. The inside of the bracket is rotatably connected with a second wire wheel 9 that cooperates with the yarn 6.

[0019] During use, the yarn bobbin 5 and the yarn 6 will rotate on the optical cable 7, enabling the tying operation of the optical cable. Moreover, when tying the yarn, the tension of the yarn 6 will pull on the first guide pulley 87, thereby transmitting the force to the hollow side plate 83 and then being detected by the tension sensor 82. The tension sensor 82 is located above the base 1 instead of being installed on the central disk 4. Therefore, it can be directly connected to an external controller through a wire, facilitating use and solving the problem that in the existing device, the connection between the tension sensor and the controller through a brush probe is not only vulnerable but also increases the usage cost and is inconvenient for maintenance. When the tension sensor 82 detects abnormal tension, the electric push rod 81 operates at this time to drive the first guide pulley 87 to move left and right, thereby adjusting the tension of the yarn 6, improving the tying effect of the optical cable, and further enhancing the tensile strength of the optical cable, thus solving the problem that the existing device can only perform tension detection but cannot adjust the tension.

[0020] Embodiment 2:

[0021] As Figure 3 shown, a motor 10 is fixedly installed on the upper surface of the base 1. The output shaft of the motor 10 is fixedly connected to a first pulley 11. The outer surface of the central tube 3 is fixedly sleeved with a second pulley 12. A synchronous belt 13 is meshed and connected between the first pulley 11 and the second pulley 12.

[0022] The rotation of the motor 10 drives the rotation of the first pulley 11. Through the synchronous belt 13 and the second pulley 12, the central tube 3 can be driven to rotate, and further, the yarn bobbin 5 and the yarn 6 can be driven to rotate.

[0023] Working principle: The rotation of the motor 10 drives the rotation of the first pulley 11. Through the synchronous belt 13 and the second pulley 12, the central tube 3 can be driven to rotate, and further, the yarn bobbin 5 and the yarn 6 can be driven to rotate. The yarn bobbin 5 and the yarn 6 will rotate on the optical cable 7, enabling the tying operation of the optical cable. Moreover, when tying the yarn, the tension of the yarn 6 will pull on the first guide pulley 87, thereby transmitting the force to the hollow side plate 83 and then being detected by the tension sensor 82. The tension sensor 82 is located above the base 1 instead of being installed on the central disk 4. Therefore, it can be directly connected to an external controller through a wire, facilitating use and solving the problem that in the existing device, the connection between the tension sensor and the controller through a brush probe is not only vulnerable but also increases the usage cost and is inconvenient for maintenance. When the tension sensor 82 detects abnormal tension, the electric push rod 81 operates at this time to drive the first guide pulley 87 to move left and right, thereby adjusting the tension of the yarn 6, improving the tying effect of the optical cable, and further enhancing the tensile strength of the optical cable, thus solving the problem that the existing device can only perform tension detection but cannot adjust the tension.
