Description

Technical Field

[0001] The invention belongs to the technical field of communication cable locking, and in particular relates to a communication cable locking device for communication engineering. Background Art

[0002] Cable is a general term for optical cables, cables and other items. Cables have many uses, mainly used for control installation, connecting equipment, transmitting electricity and other multiple functions. They are common and indispensable in daily life. During the on-site testing and debugging of communication systems, engineers sometimes need to temporarily lock the cables to ensure a stable connection between the test equipment and the system under test for effective data collection and analysis.

[0003] When temporarily locking the cables, since multiple cables need to maintain a specific layout and position to ensure that the signal transmission between them maintains high quality and consistency, multiple cables are usually locked together, which can reduce signal interference or damage that may be caused by cable movement or twisting, ensure clear and tidy wiring, and reduce confusion and potential damage risks. However, after the cables are temporarily locked, when a cable fails, since multiple cables are locked by the locking device, when it is necessary to repair the position where multiple cables are in contact, it is usually necessary for the staff to pull the locked cables outward so that the damaged cable can expose the side in contact with other cables, and then other staff can repair the cables. This repair method is relatively cumbersome and requires two or more staff to repair the cables together, resulting in low repair efficiency and greatly reducing the work efficiency when repairing the cables.

[0004] To this end, we propose a communication cable locking device for communication engineering to solve the above problems. Summary of the invention

[0038] Specifically, when multiple locked cables need to be repaired, the contacting side of the multiple cables can be exposed, making it easier for workers to repair them. This avoids the need for other workers to pull the multiple cables outwards and then repair the cables when repairing the cables, thereby improving the work efficiency and use effect of the device when repairing cables.

[0039] In the embodiment, the rolling assembly 14 includes a fourth groove 141 formed on the inner walls at both ends of the third groove 134, the top inner walls of the fourth groove 141 are fixedly connected with a fourth electric telescopic rod 142, the telescopic ends of the fourth electric telescopic rod 142 are fixedly connected with a mounting block 143, the side walls of the two mounting blocks 143 at one end are rotatably connected with the same fixed rod 144, and the rod walls of the fixed rod 144 are fixedly connected with rollers 145.

[0040] Specifically, when it is necessary to expose the contacting side of multiple cables, the roller 145 can be used to support the outer wall of the cable to prevent the cable from spreading out. At the same time, during the movement of the mounting shell 131, the continuous friction between the second clamp ring 133 and the cable can be prevented from causing damage to the outer wall of the cable, thereby improving the stability and safety of the device during use.

[0041] The operating principle of the present invention is now described as follows:

[0042] In the present invention, when it is necessary to temporarily lock the cables, the mounting plate 1 is first fixed to the wall by the mounting bolts 6, and then the staff sequentially passes the multiple cables to be locked through the fixing ring 3 and the mounting shell 131. After the cables are connected to the equipment, the first electric telescopic rod 4 is controlled to start, driving the first clamping ring 5 to move, and the multiple cables are locked. At the same time, the second electric telescopic rod 132 is controlled to start, driving the second clamping ring 133 to move, and the middle of the multiple cables is locked by the second clamping ring 133, thereby completing the locking of the multiple cables. At the same time, the third electric telescopic rod 1318 is controlled to start, driving the U-shaped plate 1319 to move, so that the arc-shaped pneumatic telescopic shell 1322 contacts the surface of the cables, and the cables are auxiliary supported, thereby reducing the influence of gravity on the cables and improving the reliability of the device.

[0043] When a cable fails and needs to be repaired, in order to expose the contacting side of the multiple cables, the first electric telescopic rod 4 and the second electric telescopic rod 132 are first controlled to retract a certain distance so that the first clamp ring 5 and the second clamp ring 133 do not lock the multiple cables. At this time, the first clamp ring 5 and the second clamp ring 133 can assist in supporting and limiting the multiple cables to prevent the multiple cables from spreading out. Then, the forward and reverse motor 10 is controlled to start, driving the threaded screw 8 to rotate, so that the movable plate 11 drives the mounting shell 131 to move to one end of the cable fault position, so that the cable fault position is located between the mounting shell 131 and the arc-shaped pneumatic telescopic shell 1322, and then the corresponding The air pump 1323 is started to inject air into the arc-shaped pneumatic telescopic shell 1322, so that the telescopic end of the arc-shaped pneumatic telescopic shell 1322 extends out to wrap a single cable, thereby completing the fixation of the single cable. Then, the corresponding first motor 1315 is controlled to start, driving the support rod 1313 to rotate, so that the fourth circular gear 1314 rotates. During the rotation of the fourth circular gear 1314, the third circular gear 1312 meshing with the fourth circular gear 1314 is driven to rotate. During the rotation of the third circular gear 1312, the first circular gear 1310 is driven to rotate, so that the multiple second circular gears 1311 meshing with the first circular gear 1310 rotate. As a result, the plurality of support rods 138 are rotated accordingly. During the rotation of the support rods 138, the worm 139 is driven to rotate, so that the worm wheel 137 meshing with the worm 139 is rotated accordingly, thereby driving the rotating rod 136 to rotate, so that the guide plate 1316 drives the fixed plate 1317 and the third electric telescopic rod 1318 to rotate around the rotating rod 136, thereby driving the U-shaped plate 1319 and the arc-shaped pneumatic telescopic shell 1322 to rotate, driving the plurality of cables to move outward, and in the process of the arc-shaped pneumatic telescopic shell 1322 driving the cables to move outward, the second motor 1320 is controlled to start, driving the side rod 1321 to rotate, so that the arc-shaped pneumatic telescopic shell 1322 continuously changes its angle. The arc-shaped pneumatic telescopic shell 1322 can always be perpendicular to the ground during the rotation of the U-shaped plate 1319, thereby preventing the pressure on the cable surface from causing damage during the process of pulling up the cable. After the multiple cables are moved outward, the contacting side of the multiple cables is exposed, which is convenient for the staff to repair them. When the multiple locked cables need to be repaired, the contacting side of the multiple cables is exposed, which is convenient for the staff to repair them, avoiding the need for other staff to pull the multiple cables outward and then repair the cables when repairing the cables, thereby improving the working efficiency and use effect of the device when repairing the cables;

[0044] When the installation shell 131 is driven to move to the position of the cable that needs to be repaired, the fourth electric telescopic rod 142 is controlled to start and shrink, driving the installation block 143 to move upward, so that the fixing rod 144 and the roller 145 move accordingly, so that the roller 145 can contact the outer wall of the cable, which is convenient for supporting the cable. When it is necessary to expose the contact side of multiple cables, the roller 145 can be used to support the outer wall of the cable to prevent the cable from spreading. At the same time, during the movement of the installation shell 131, the continuous friction between the second clamping ring 133 and the cable can be prevented from causing damage to the outer wall of the cable, thereby improving the stability and safety of the device when in use.

[0045] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
