Description

Technical Field

[0001] This invention relates to the field of machinery, specifically to a device and method for maintaining tension at the end of an optical cable core. Background Technology

[0002] The basic structure of an optical cable generally consists of several parts, including the cable core, reinforcing steel wires, filler, and sheath. In addition, depending on the needs, there may be waterproof layer, buffer layer, insulated metal conductors, and other components.

[0003] Chinese patent CN103935833B discloses a fiber optic composite cable optical unit cabling and laying device. This device adjusts the laying tension of the optical unit by changing the height of a swing-arm tension wheel assembly. However, the swing-arm tension wheel assembly itself only serves as a signal trigger source, requiring the adjustment of the drive motor's speed to regulate the laying speed. This constant speed adjustment of the drive motor easily causes the laying tension of the optical unit to fluctuate, increasing its volatility. Summary of the Invention

[0004] In view of the problems mentioned in the prior art, the present invention provides a device and method for maintaining tension at the end of optical cable core laying, which can avoid the occurrence of the above problems.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A tension holding device for the end of optical cable core laying includes a base plate. The base plate is provided with a winding mechanism and a pressing mechanism. The winding mechanism includes two vertical plates, and a central shaft is installed between the two vertical plates. A winding wheel is fixedly connected to the central shaft. A drive motor is fixedly connected to the vertical plates. The output shaft of the drive motor is connected to the winding wheel. The winding wheel is provided with multiple winding grooves, and optical cable cores are wound on the winding grooves.

[0007] Furthermore, the winding groove includes a first winding groove, a second winding groove, and a third winding groove, and the optical cable core is wound sequentially on the third winding groove, the second winding groove, and the first winding groove.

[0008] Furthermore, the pressing mechanism includes two fixed plates, each with a vertical slide groove. A sliding block is slidably fitted within the vertical slide groove, and a rotating shaft is provided between the two sliding blocks. A lower pressing wheel is rotatably connected to the rotating shaft. A lower sliding plate is provided at the bottom of the vertical slide groove, and the lower sliding plate moves along the vertical slide groove. A pressure sensor is provided on the lower sliding plate, and a flexible spring is provided between the pressure sensor and the sliding block. An optical cable core is placed below the lower pressing wheel. A lower insertion hole is provided at the bottom of the vertical slide groove, and a top rod is provided within the lower insertion hole. A side passage groove is provided on one side of the lower insertion hole, and a screw is connected to the top rod. After the screw passes through the side passage groove, a fastening nut is threaded onto it. A ball is welded to the end of the screw, and a conical sleeve is installed on the ball.

[0009] Furthermore, the conical sleeve is provided with a rubber ball sleeve that mates with the sphere, and the rubber ball sleeve is provided with an insertion hole for accommodating the sphere.

[0010] A method for maintaining tension at the end of optical cable core release involves the optical cable core passing through a pressing mechanism, positioning it at the bottom of the lower pressing wheel, then passing around the three winding slots of the winding wheel before exiting the winding mechanism. A drive motor is activated, causing the lower pressing wheel to press down on the optical cable core. A pressure sensor transmits a signal to a control board, which in turn transmits a signal to a display screen. The position of the top rod relative to the lower insertion hole is adjusted based on the signal displayed on the screen, and then tightened by a fastening nut.

[0011] The beneficial effects of this invention are: the invention utilizes a winding mechanism to maintain a stable tension at the output end of the optical cable core, and uses a wire pressing machine to adjust the tension at the input end of the optical cable core, avoiding situations where the tension is too high or too low, reducing tension fluctuations, and solving the shortcomings of the prior art.

[0020] In operation, when the optical cable core is wound on the winding wheel, the drive motor can drive the winding wheel to rotate. The wire inlet end of the winding wheel is brought close to the third winding groove and wound. After passing through the second winding groove and the first winding groove, it comes out. Regardless of the tension at the wire inlet end of the optical cable core, the tension at the wire outlet end of the optical cable core is determined by the drive motor and can maintain a constant tension.

[0022] In a more detailed design, the conical sleeve contains a rubber ball sleeve 316 that mates with the sphere, and the rubber ball sleeve has an insertion hole for accommodating the sphere.

[0023] A method for maintaining tension at the end of the optical cable core is as follows: the optical cable core is passed through the pressure mechanism, and after the optical cable core is at the bottom of the lower pressure wheel, it passes around the three winding grooves of the winding wheel and then passes out of the winding mechanism.
