Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and specifically to a cable laying device. Background Technology

[0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. Depending on the application, it can be divided into several laying methods such as overhead, underground (pipe and direct burial), underwater, wall and tunnel. The rational selection of cable laying method is very important to ensure the transmission quality, reliability and construction and maintenance of the line.

[0003] In the existing technology, overhead cables are generally laid on cable trays. Currently, during the laying process, the cables are usually laid on the cable trays manually, which not only has low work efficiency, but also makes the cables easy to bend, twist and knot during the laying process, further reducing work efficiency.

In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] like Figures 1-4 As shown, this utility model discloses a cable laying device, including a cable laying mechanism 100 and multiple conductor mechanisms 200 disposed on a cable tray 300. The multiple conductor mechanisms 200 are equally spaced on the cable tray 300, and the cable is laid on the cable tray 300. During cable laying, the multiple conductor mechanisms 200 are placed on the cable tray 300, and the cable is led out by the cable laying mechanism 100 and laid through the multiple guiding mechanisms.

[0031] The wire feeding mechanism 100 includes a bracket 11, a wire feeding rod 12 is provided on the bracket 11, and a plurality of wire feeding rings 13 are provided at equal intervals on the wire feeding rod 12. The cable passes through the wire feeding rings 13, and the bottom of the wire feeding rings 13 is provided with two support rods 16 connected to the wire feeding rod 12.

[0032] Multiple guide rollers 14 are rotatably mounted on the pay-off ring 13, and are arranged at equal intervals on the pay-off ring 13. The pay-off ring 13 has slots at corresponding positions to accommodate the guide rollers 14, and guide rods 15 connected to the pay-off ring 13 are installed within the slots. The guide rollers 14 are rotatably fitted onto the guide rods 15. A pad layer of elastic material, such as silicone or rubber, is provided on the surface of the guide rollers 14. The outer diameter of the guide rollers 14 is larger than the outer diameter of the cross-section of the pay-off ring 13, meaning the outer wall of the guide rollers 14 is located inside the inner edge of the pay-off ring 13. When the cable passes through the pay-off ring 13, the cable makes rolling contact with the outer wall of the guide rollers 14.

[0033] The conductor mechanism 200 includes a crossbeam 21. At the bottom of each end of the crossbeam 21, there are locking blocks 25 that are connected to the cable tray 300. The bottom of the locking block 25 is provided with a locking groove 26. The side wall of the locking groove 26 near the middle of the crossbeam 21 is provided with a first locking plate 29. The distance between the outer walls of the first locking plates 29 in the locking grooves 26 on both sides of the crossbeam 21 is adapted to the distance between the inner walls of the two side plates of the cable tray 300. A movable second locking plate 210 is provided in the locking groove 26 on the side of the first locking plate 29.

[0034] The second card plate 210 has a sliding groove 211 on the side wall of the slot 26 away from the first card plate 29. The opening trajectory of the sliding groove 211 is perpendicular to the second card plate 210. A slider 212 is slidably arranged in the sliding groove 211. Two spring telescopic rods 213 are provided between the slider 212 and the second card plate 210. The spring telescopic rods 213 are arranged perpendicular to the second card plate 210.

[0035] An adjusting screw 28 is rotatably connected to the side wall of the slider 212 away from the second clamping plate 210. The adjusting screw 28 extends out of the clamping block 25 and is arranged perpendicular to the second clamping plate 210. A knob is provided at the free end of the adjusting screw 28. A threaded cylinder 27 that is threadedly engaged with the adjusting screw 28 is provided at a corresponding position on the outer wall of the clamping block 25.

[0036] Rotating the knob adjusts the screw 28, which moves in conjunction with the threaded cylinder 27, causing the slider 212 to slide within the groove 211. The slider 212, via the spring telescopic rod 213, causes the second clamping plate 210 to slide closer to or further away from the first clamping plate 29, thereby adjusting the distance between the first clamping plate 29 and the second clamping plate 210.

[0037] The bottom ends of the first card plate 29 and the second card plate 210 are both inclined surfaces, which gradually slope outward from top to bottom towards the outside of the card slot 26, so that the bottom ends of the first card plate 29 and the second card plate 210 form a flared structure.

[0038] The bottom of the cross frame 21 is provided with multiple threaded holes arranged in a straight line at equal intervals. A guide rod 24 is threadedly connected to the threaded hole. Two limiting rings 23 are coaxially connected to the guide rod 24. One of the limiting rings 23 is located at the bottom end of the guide rod 24. A guide tube 22 is coaxially rotatably sleeved on the guide rod 24 between the two limiting rings 23.

[0039] When laying cables, install conductor rods 24 at the bottom of the crossbeam 21 in advance according to the number of cables, cable outer diameter, and cable distance. Install multiple conductor mechanisms 200 at equal intervals on the cable tray 300, with a spacing of three meters between the conductor mechanisms 200. During installation, rotate the adjusting screw 28 so that the distance between the first clamping plate 29 and the second clamping plate 210 is less than the thickness of the side plate of the cable tray 300. Then, place the crossbeam 21 onto the cable tray 300, aligning the two clamping slots 26 on both sides of the crossbeam 21 with the side plate of the cable tray 300, and then press down. During the pressing down process, as the side plate of the cable tray 300 enters the clamping slots 26... The side plate of the cable tray 300 first contacts the inclined surface at the bottom of the first clamping plate 29 and the second clamping plate 210. Guided by the inclined surface, the second clamping plate 210 slides away from the first clamping plate 29, and the spring telescopic rod 213 is compressed. After the side plate of the cable tray 300 is fully inserted into the clamping groove 26, the first clamping plate 29 and the second clamping plate 210 are clamped on the side plate of the cable tray 300. The elastic force of the spring telescopic rod 213 makes the second clamping plate 210 in close contact with the side plate of the cable tray 300, and the conductor mechanism 200 is fixed. Then, the cable laying mechanism 100 is installed at the end of the cable tray 300 where the cable is laid, and the cable is led out and passed through the corresponding cable laying ring 13. The cable passing through the cable laying ring 13 then passes through the two corresponding conductor tubes 22 in the multiple conductor mechanisms 200 in sequence, realizing the rapid laying of the cable.

[0040] In this invention, when laying cables on the cable tray 300, multiple cables are released by the cable-laying mechanism 100 and then passed through the conductor mechanism 200, thus achieving rapid cable laying. During the laying process, the cables can be pulled. Under the guidance and separation of the conductor mechanism 200, the cables will not bend, twist, or knot, greatly improving the efficiency of the laying operation. By rotating the adjusting screw 28, the distance between the first clamping plate 29 and the second clamping plate 210 can be adjusted to make the conductor mechanism 200 match the thickness of the side plate of the cable tray 300. By adjusting the position of the conductor rod 24, it can be applied to cable laying operations with different cable outer diameters, different numbers of cables, and different laying position requirements.

[0041] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
