Description

Technical Field

[0001] This utility model belongs to the field of communication cable rack technology, and in particular relates to a communication cable racking device. Background Technology

[0002] Communication cables are cables used to transmit communication signals, such as optical fiber cables. By laying communication cables, communication signals can be transmitted over long distances.

[0003] Therefore, communication cables are characterized by their long length and high density during installation. During installation, cables are continuously unwound from the cable reel, and because the cable length is often quite large, the total length of unwound cables is substantial. Consequently, the amount of cable wound on the cable reel is very large, resulting in a significant weight for the entire cable reel, especially for large-diameter cables.

[0004] To save effort when unwinding cables, the current common practice is to place the cable on a rotating turntable. However, in actual operation, it has been found that when the cable roll is heavy, and the turntable is connected to the base via a rotating shaft, the heavy cable roll is not accurately placed in the center of the turntable (it is difficult to ensure that the cable roll is placed in the center of the turntable during unwinding). In addition, the increased wear of the shaft causes the turntable to vibrate during unwinding. Therefore, the stability and smoothness of unwinding are not high. In severe cases, the turntable with poor rotational stability is prone to shaft breakage and the turntable and cable tipping over under the weight of the heavy cable.

[0005] Therefore, one of the difficulties in actual cable laying is how to lay the heavy cable rolls in a stable, smooth and safe manner, which is very important for improving the construction efficiency and ensuring the safety of cable laying.

[0006] Especially when dealing with large-diameter cables, cable reels are very heavy. Traditional cable laying devices are not only unstable and unsafe, but also bulky and difficult to move. Therefore, the above-mentioned defects are the key factors that affect the efficiency of cable laying and installation. Utility Model Content

[0038] Example 1

[0039] like Figure 1-6 As shown, a communication cable laying device includes a communication cable laying and laying mechanism.

[0040] Specifically, the communication cable laying mechanism includes a lower fixing ring seat 2 (made of steel). To improve the stability of the lower fixing ring seat 2, a lower inner support structure 21 is fixedly connected inside the lower fixing ring seat 2. Specifically, the lower inner support structure includes a lower central ring 211 concentrically arranged with the lower fixing ring seat 2, and a plurality of lower support rods 212 are welded between the lower central ring 211 and the inner sidewall of the lower fixing ring seat 2.

[0041] Meanwhile, the top of the lower fixed ring seat 2 is provided with an upper cable release ring seat 3. Similarly, in order to improve the structural stability of the upper cable release ring seat 3, an upper inner support structure 31 is fixedly connected inside the upper cable release ring seat 3.

[0042] The top of the upper inner support structure 31 is equipped with a cable reel feeding structure. The upper inner support structure includes an upper central ring concentrically arranged with the upper cable reel seat 3, and several upper support rods are welded between the upper central ring and the inner sidewall of the upper cable reel seat 3.

[0043] The heavy cable is placed on the upper cable release ring seat 3 and the upper inner support structure for unwinding. However, when the crane places the cable roll on the upper inner support structure, it is difficult to ensure that the center of gravity of the cable roll is located at the center of the upper cable release ring seat 3. Therefore, in order to improve the stability of the upper cable release ring seat 3 during the cable unwinding process and avoid the technical defects of shaking and tipping of the upper cable release ring seat 3 during rotation due to the unstable center of gravity of the cable roll, several circumferentially distributed clamping wheel mechanisms are installed between the upper cable release ring seat 3 and the lower bottom fixed ring seat 2.

[0044] That is, the upper cable ring seat 3 is rotated by pressing down and clamping it through the clamping wheel mechanism, so as to improve the stability of rotation.

[0045] Specifically, the clamping wheel mechanism includes an upper wheel structure 5 that rolls against the top of the upper cable-laying ring seat 3. The clamping wheel mechanism also includes several lower wheel structures installed at the bottom of the upper cable-laying ring seat 3. Each lower wheel structure includes a lower rotating wheel that rolls against the top of the lower fixed ring seat 2. During operation, the lower rotating wheel and the upper cable-laying ring seat 3 support the load on the lower fixed ring seat 2 and rotate during cable laying. During cable laying, the top of the upper cable-laying ring seat 3 is pressed against the lower wheel structures, which press down on the top edge of the upper cable-laying ring seat 3. Therefore, this method greatly improves the stability of the upper cable-laying ring seat 3 during cable laying. For example, if the center of gravity of the cable roll is unstable, the top of the upper cable-laying ring seat 3 is pressed down, thus preventing the upper cable-laying ring seat 3 from easily shaking under pressure.

[0046] The aforementioned upper wheel structure 5 includes an upper rotating wheel 51, and an adjustment frame 52 (in C-shape) is installed on the top of the upper rotating wheel 51. A fixed seat 53 for installing the adjustment frame 52 is fixedly connected to the outer side wall of the lower bottom fixed ring seat 2. The adjustment frame 52 is installed on the fixed seat 53 through an adjustment structure.

[0047] Specifically, the adjustment structure includes an adjustment screw 54 vertically fixed to the top of the fixed base 53, and the adjustment screw 54 is slidably connected to the adjustment frame 52; a pressing positioning nut 541 for pressing down the adjustment frame 52 is threaded onto the adjustment screw 54.

[0048] Before releasing the cable, the upper rotating wheel 51 is pressed against the upper cable release ring seat 3. Then, the lower positioning nut 541 is pressed down and adjusted. Under the squeezing and pushing of the lower positioning nut 541, the adjusting frame 52 is kept facing downward and tensioned, and the upper rotating wheel 51 is pressed firmly against the upper cable release ring seat 3.

[0049] The top of the aforementioned lower base fixing ring seat 2 is provided with an annular groove A, and the lower rotating wheel 4 is limited to rolling within the annular groove A.

[0050] Similarly, an annular groove is provided at the top of the upper cable-laying ring seat 3, and the upper rotating wheel 51 is limited to rolling within the annular groove. During this process, the upper rotating wheel 51 and the lower rotating wheel 4 are limited to rolling within the annular groove. This method reduces the risk of the upper rotating wheel 51 and the lower rotating wheel 4 derailing from the track, and further improves the stability of the rotating cable-laying.

[0051] Example 2

[0052] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 1, a motor 32 is installed in the lower central ring to achieve smooth cable feeding. The output shaft of the motor 32 passes through the upper central ring and is fixedly installed at the bottom center of the coil feeding structure.

[0053] Specifically, the unloading structure includes a feeding seat 61 (disc-shaped, detachable by bolts) fixedly installed at the top of the upper inner support. A limiting rod 62 for limiting the cable roll is fixedly connected to the top center of the feeding seat 61. Several clamping structures 7 are fixedly connected to the upper end of the limiting rod 62 and are pressed against the inside of the cable roll. The clamping structure 7 includes a threaded tube seat 71 (with a threaded cavity of a certain depth) welded to the limiting rod 62. A clamping screw 72 is threadedly connected to the threaded tube seat 71.

[0054] After the cable reel is placed in, the cable reel passes through the limit rod 62. At this time, even if the cable reel is misplaced (center of gravity misplaced), it cannot correct the heavy cable. The above embodiment still achieves stable cable laying.

[0055] During operation, the cable reel rotates continuously under the drive of the motor to unwind the cable.

[0056] To compress the cable coil onto the drum and increase unwinding stability, the aforementioned clamping structure abuts against the inner wall of the cable coil drum. Specifically, the clamping screw 72 is rotated until it abuts against the inner wall of the drum, thereby appropriately increasing the stability of the cable coil during unwinding.

[0057] Example 3

[0058] like Figure 1-6 As shown, based on the structure of Embodiment 2, in order to facilitate the relocation of the entire device including the cable reel, the above-mentioned communication cable laying device also includes a traveling trolley structure. The traveling trolley structure includes a frame 11, on which a plurality of traveling rollers 12 are installed. The communication cable laying and unloading mechanism is installed on the top of the frame. Specifically, to increase stability, the entire device can be locked by bolting it to the fixed seat 53. Specifically, the bolts are tightened from the bottom of the frame 11 upwards and then tightened to the fixed seat 53 supported on the frame to lock the entire device.

[0059] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
