Description

Technical Field

[0001] The invention relates to the technical field of cable laying, and in particular to a weak-current cable laying device for a communication room. Background Art

[0002] The cable laying of the communication room is a crucial and delicate process, which is directly related to the stability and reliability of the entire communication system. Therefore, before starting the laying, the cable laying of the room must be carefully planned and designed, which covers the direction of the cable, the required length, the connection equipment and other aspects. According to the design plan, carefully prepare the necessary materials such as the required cables, connectors, fixings, and identification plates.

[0003] In the machine room, we install the cable ducts accurately in the designated locations according to the precise guidance of the design drawings. Then, we flexibly adjust the width and height of the cable ducts according to the thickness and quantity of the cables to ensure that the cables can be easily and neatly placed in the cable ducts. To further enhance the stability of the cables, we skillfully use fixings to firmly fix the cables in the cable ducts at the entrances and exits, at the turns, and at certain intervals (e.g. 1 meter).

[0004] In traditional technology, construction workers mainly use two methods: binding and buckling. Binding usually relies on tools such as ropes or plastic belts to tightly tie the cables and fix them in the cable duct; while buckling is more professional, it uses special buckles to firmly fix the cables in the duct. However, these traditional manual operation methods are relatively cumbersome and inefficient. Summary of the invention

[0049] In one embodiment of the present invention, Figure 4 As shown, the transmission member 301 includes a driving component 3011 , a rotating shaft 3012 and an incomplete gear 3013 .

[0050] The driving component 3011 is arranged on the feeding mechanism 207 , the rotating shaft 3012 is arranged at the output end of the driving component 3011 , and the incomplete gear 3013 is arranged on the rotating shaft 3012 .

[0051] It should be noted that the driving component 3011 is a servo motor, which is operated by controlling the switch and the power supply. The driving component 3011 drives the incomplete gear 3013 to rotate through the rotating shaft 3012. When the incomplete gear 3013 rotates, it is meshed and connected with the movable frame 3021. A rack is provided on the movable frame 3021. When the driving component 3011 is operated, it pushes the pressing piece 2053 to move up and down.

[0055] Furthermore, in order to ensure that the buckle is locked on the cable, the number of meshing teeth on the incomplete gear 3013 is set according to the downward movement spacing of the buckle and the fixed distance required for cable laying.

[0056] In one embodiment of the present invention, Figure 5 As shown, the guide wire mechanism 206 includes a conveying roller 2062 of a baffle 2061 .

[0057] The baffle plate 2061 is disposed on the fixed base 101 , and there are multiple groups of conveying rollers 2062 , which are respectively disposed on the baffle plate 2061 .

[0058] It should be noted that the conveying roller 2062 is arranged on the baffle 2061, and the cable is limited by the conveying roller 2062 during the conveying process.

[0059] In one embodiment of the present invention, Figure 6 As shown, the transmission mechanism 202 includes a transmission component 2021, a transmission turbine 2022, a fixed seat 2023, a movable shaft 2024, a transmission worm 2025 and an internal threaded collar 2026.

[0060] The transmission component 2021 is arranged on the limiting frame 201, the transmission turbine 2022 is arranged on the output end of the transmission component 2021, and the fixed seat 2023 is arranged on the limiting frame 201. The movable shaft 2024 is rotatably arranged on the fixed seat 2023, the transmission worm 2025 is arranged on the movable shaft 2024, and the transmission turbine 2022 and the transmission worm 2025 are meshed and connected.

[0061] It should be noted that the transmission component 2021 described in this embodiment is a stepper motor, and the transmission component 2021 is operated by connecting the control switch and the power supply. When the transmission component 2021 is in operation, the transmission turbine 2022 is driven to rotate through the reducer, and the transmission turbine 2022 is meshed and connected with the transmission worm 2025, driving the rotation of the transmission worm 2025. The internal threaded collar 2026 is connected to the movable bracket 204, and when the transmission worm 2025 rotates, the movable bracket 204 is driven to move and adjust the position through the internal threaded collar 2026.

[0062] Specifically, the steps for laying weak-current cables in a communication room are as follows: place the cable to be laid on the winding roller 103, then pass one end of the cable through the laying component 20 and the driving component 30 in sequence, the cable passes through the cable trough 203 and enters the pressing mechanism 205, and the buckle for fixing the cable is placed in the feeding mechanism 207. The cable is limited by the conveying roller 2062 during transmission.

[0063] According to the position where the cable needs to be laid, the laying component 20 drives the movable bracket 204 to slide on the upper limit of the limit frame 201, and the operation of the transmission component 2021 drives the transmission turbine 2022 to rotate, and the transmission turbine 2022 and the transmission worm 2025 are engaged and connected, which drives the internal threaded ring 2026 to rotate, and the internal threaded ring 2026 is connected to the movable shaft 2024, which drives the wire groove 203 and the pressing mechanism 205 to move and adjust.

[0064] When the cable passes through the hollow frame 2051, it passes through and passes through the conveying roller 2062, and then the buckle moves in the feeding mechanism 207. The buckle will first fall into the top material piece 2052. At this time, the operating driving component 3011 drives the incomplete gear 3013 to rotate through the rotating shaft 3012. The incomplete gear 3013 rotates and drives the movable frame 3021 to move up and down. The movable frame 3021 drives the movable plate 20532 to move up and down through the fixed bracket 3022 during the movement. The movable plate 20532 simultaneously pushes the pressing plate 20534 downward during the downward movement. The downward movement of the pressing plate 20534 presses down the buckle on the pressing piece 2053, presses the buckle down and presses it on the cable, thereby fixing the cable.

[0065] In summary, a low-voltage cable laying device for a communication room according to an embodiment of the present invention adopts a method of stably conveying cables. During the process of conveying and arranging the cables, the buckles are sequentially clamped on the cables, and the cables are clamped and fixed during the arrangement process, which saves time and effort and improves wiring efficiency.
