Description

Technical Field

[0002] Communication cables are a general term for various wires that transmit electrical or optical signals, mainly including covered wires, overhead wires, communication cables and communication optical cables.

[0003] In the construction process of communication projects, winding facilities are often used to reel in and unwind communication cables. When laying multiple cables, existing winding devices need to reel in and unwind multiple different cables, and when multiple cables are unwound at the same time, the cables cannot be sorted. When one or more cables are broken or unwound, it cannot be detected immediately, resulting in single or multiple cables being disconnected. The broken cables and other cables must be unwound to the end where they are used before the broken cables are discovered. When renewing the cables, multiple unwound cables need to be returned to the winding point for renewing, resulting in a complicated process. In addition, since multiple cables are driven individually for retraction and unwinding and cannot be performed synchronously, the cables cannot be retracted and unwound synchronously.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In order to better understand the communication cable retracting device for communication engineering provided by the present embodiment, the existing communication cable retracting device is briefly introduced below. In the prior art, when multiple cables are retracted and released by a single drive, the multiple cables need to be retracted on a wire roller. However, multiple cables are easily entangled when wound on a single wire roller, and it is difficult to separate the cables. Secondly, if the multiple cables are not placed on a wire roller for retraction, each wire roller needs to be driven by a separate drive for retraction, which increases the retraction cost. The specification aims to solve the above technical problems. The embodiment of the present application provides a communication cable retracting device for communication engineering.

When the cable on a single pay-and-wind roller 2 is broken or fully released, one end of the cable is not restricted by the winding of the pay-and-wind roller 2, resulting in no tension effect on the cable. When the detection part 5 cannot detect the tension of the cable, it is fed back to the locking part 6. The locking part 6 clamps the broken cable to prevent the single or multiple cables from being decoupled due to the breakage. By locking the cable, it is convenient to connect the cable and replace the pay-and-wind roller 2, thereby improving the convenience of cable unwinding and avoiding rework of the cable after unwinding.

[0024] Specifically, the motor drives the driving rod 71 to rotate, and the driving rod 71 drives the first gear 72 and the second gear 73 to rotate together. The first gear 72 drives the inner gear ring 432 and the inner rotating ring 43 to rotate. During the rotation of the second conical teeth 431 on the inner rotating ring 43, the second conical teeth 431 are connected with the second oblique tooth grooves 411 on the inner wall of the driving roller 41, thereby driving the driving roller 41 to rotate counterclockwise. The rotation of the second gear 73 drives the outer gear ring 332 and the outer rotating ring 33 to rotate. During the rotation of the first conical tooth 331 at one end of the ring 33, the first conical tooth 331 docks with the first oblique tooth groove 311 on the inner wall of the wire drawing roller 31, thereby driving the wire drawing roller 31 to rotate clockwise, causing the wire drawing roller 31 and the driving roller 41 to rotate in the same direction, straightening the cable passing therebetween, and the first rotating ring 3 and the second rotating ring 4 limit the rotation of the outer rotating ring 33 and the inner rotating ring 43, and through a single drive, multiple wire drawing rollers 31 and the driving roller 41 are driven to rotate in the same direction, saving driving energy.

[0025] Example 2: Reference Figure 7, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that a mounting bracket 441 is provided on the second mounting ring 44, a clamping roller 442 is axially connected to the mounting bracket 441, a linkage gear 443 is sleeved on the driving shaft of the clamping roller 442, a driving gear 412 meshing with the linkage gear 443 is sleeved on the outer wall of the driving roller 41, and when the driving roller 41 rotates, it drives the driving gear 412 to rotate, and the driving gear 412 drives the linkage gear 443 to rotate, and then drives the clamping roller 442 to rotate in the opposite direction, and an annular groove is provided on the surfaces of the clamping roller 442 and the driving roller 41, and the annular groove is used for the cable to pass through, and the clamping roller 442 and the driving roller 41 rotate in the opposite direction to clamp the cable through the annular groove, so as to facilitate the automatic release of the cable when the cable is unwound, thereby improving the convenience of releasing the cable.

[0026] Example 3: Reference Figure 8 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that the detection member 5 includes a fixed support 51 and a tensioning plate 52. The fixed support 51 is installed on the first mounting ring 34. Two tensioning plates 52 are arranged on the fixed support 51. The two tensioning plates 52 are movably installed between each other. The two tensioning plates 52 are provided with threading holes 521 for cable penetration. The spacing between the two tensioning plates 52 is adjustable to facilitate the passage of cables of different sizes. The fixed support 51 is connected to the first mounting ring 34 through a torsion spring. Installation, the locking member 6 includes an upper clamping plate 61, a lower clamping plate 62 and a linkage member 63, the upper clamping plate 61 and the lower clamping plate 62 are respectively installed at the two ends of the linkage member 63, the linkage member 63 is fixed on the first mounting ring 34, the linkage member 63 includes a linkage screw rod 631 and a wire rod 632, the upper clamping plate 61 and the lower clamping plate 62 are respectively sleeved on the two ends of the linkage screw rod 631 and the wire rod 632, a plurality of shaft rods are arranged on the first mounting ring 34, the shaft rods are sleeved by belts, and the linkage screw rod 631 and the fixed pillar 51 are both sleeved by belts.

[0027] During the cable pay-out process, the tensioning plate 52 is limited by the cable, so that the torsion spring is in a compressed state. When the cable is broken and one end is not pulled, the torsion spring drives the fixed support 51 to rotate, and the rotation of the fixed support 51 drives the tensioning plate 52 to rotate, and the rotation of the fixed support 51 drives the linkage screw rod 631 to rotate through the belt. When the linkage screw rod 631 rotates, it drives the upper clamping plate 61 and the lower clamping plate 62 to approach each other, and clamps the cable between the upper clamping plate 61 and the lower clamping plate 62, effectively realizing the cable off-line while clamping and locking the cable, effectively avoiding the cable off-line, and detecting and locking through the linkage between the detection member 5 and the locking member 6, thereby improving the locking smoothness.

[0028] The clamping surfaces of the upper clamping plate 61 and the lower clamping plate 62 are both provided with semicircular holes for the cable to pass through, and multiple circles of friction semi-ring pads are arranged in the semicircular holes. When the upper clamping plate 61 and the lower clamping plate 62 clamp the cable, the multiple circles of friction semi-ring pads contact the cable, increasing the friction force, improving the clamping force, and effectively preventing the cable from breaking free.
