[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy and information and to achieve electromagnetic energy conversion. In a broad sense, wires and cables are also referred to as cables. In a narrow sense, cables refer to insulated cables, which can be composed of one or more insulated wire cores, and their respective coatings, protective layers, and outer sheaths. Cables can also have additional uninsulated conductors.

[0018] Example: A preferred embodiment of the present invention is described in detail below. A wire-laying device for long-distance construction of high-voltage cables comprises a base 1, with protrusions extending from the four corners of the base 1, and positioning supports 2 provided at the outer ends of the four protrusions. A through hole is provided in the center of the positioning support 2, and a gripping nail 3 with a tapered lower end is installed in the through hole. At the same time, universal wheels 4 are installed on the inner sides of the four corners of the bottom surface of the base 1; the gripping nail 3 is used to fix the position of the wire-laying device, and the universal wheel 4 facilitates the movement of the wire-laying device. A fixed vertical plate 5 is symmetrically welded vertically to the edges of both ends of the base 1, and a top plate 14 is fixedly welded inwardly to the upper end of the fixed vertical plate 5. A threaded barrel 16 is installed in the middle position of the top plate 14, and a screw 17 is installed in the threaded barrel 16. The upper end of the screw 17 is connected to a crank 18 for operating the lifting and lowering of the screw 17. The lower end of the screw 17 is connected to a rotating block 15, which is installed in a rotating seat 20 with a stepped hole inside, so that the rotating block 15 can rotate in the rotating seat 20; the lower end of the rotating seat 20 is connected to the middle position above the guide block 7 with through holes at both ends (such as Figure 1 、 Figure 2 and Figure 3 As shown). Through holes are provided at both ends of the guide block 7, which are connected to the guide rods 6 provided at both ends below the top plate 14. The lower ends of the guide rods 6 are fixedly connected to the base 1, so that the guide block 7 can slide up and down on the guide rods 6. When the guide block 7 needs to be raised or lowered, the screw 17 can be rotated by the crank 18 to drive the guide block 7 to move on the guide rod 6. Ear blocks 19 are symmetrically provided under the guide block 7 (as shown). Figure 4 and Figure 5 As shown, the inner and lower sides of the ear blocks 19 are each provided with a protrusion that mates with a bracket block 8, which has two ridges on its outer sides. The bracket block 8 is provided with a U-shaped slot 9, which is used to position the bearings 10 at each end of the rotating shaft 11. An I-shaped cable drum 13 is mounted on the rotating shaft 11 and is positioned on the rotating shaft 11 by a retaining groove 12. When the I-shaped cable drum 13 rotates, the rotating shaft 11 rotates simultaneously, and the bearings 10 at each end of the rotating shaft 11 remain positioned and rotate within the U-shaped slot 9 in the center of the bracket block 8. The cable wound on the I-shaped cable drum 13 passes through a guide cylinder 22 on a fixed frame 21 on one side of the base 1. The cable also passes through an arc-shaped cable groove 29 in the fixed frame 21. A slide card 26 above the arc-shaped cable groove 29 is moved on a slide rod 24 by a spring 27, ensuring that the output cable passes stably through the guide cylinder 22 on the two side plates of the fixed frame 21.

[0019] After the cable is wound up through the I-shaped cable drum 13, when installing the I-shaped cable drum 13, the handle 18 is first rotated to lower the guide block 7 through the screw 17. The rotating shaft 11 in the slot 9 of the support block 8 below the guide block 7 is then removed and the rotating shaft 11 is inserted into the I-shaped cable drum 13. The rotating shaft 11 and the I-shaped cable drum 13 are then placed together in the slot 9. The guide block 7 is then raised through the screw 17, thereby raising the I-shaped cable drum 13 at the same time, so that the I-shaped cable drum 13 is suspended in the air, making it easier to release the cable. When releasing the cable, the release end of the cable is passed through the guide drums 22 on both sides of the fixing frame 21 and simultaneously passed through the arc-shaped cable groove 29 and the "Ω"-shaped sliding card 26. When the cable is not being paid out, the spring 27 can elastically press the slide card 26 downward, and the slide card 26 and the arc-shaped cable groove 29 cooperate to clamp and secure the cable, thereby preventing the cable from loosening. When the cable needs to be paid out, the staff pulls the cable, which is then tensioned and further stretched between the two guide cylinders 22. At this time, the slide card 26 is pulled away from the bottom of the arc-shaped cable groove 29 by the cable, and the cable is no longer clamped and fixed, and the cable can now be quickly paid out.

[0020] The rectangular base 1 of this utility model is equipped with universal wheels 4 at each of its four corners, enabling the device to be freely moved. Positioning supports 2 are fixedly connected to the outer protrusions at the four corners of the base 1. Gripping spikes 3 are slidably connected to the positioning supports 2. The lower ends of the gripping spikes 3 are tapered, with the cone facing downward, allowing them to be inserted into the ground. These gripping spikes 3 then limit and secure the base 1, preventing the device from tipping over when pulled by cables.

[0021] A limiting slot block 12 is fixedly installed in the key slot of the rotating shaft 11, and a key slot corresponding to the limiting slot block 12 is provided on the inner wall of the shaft hole of the I-shaped cable barrel 13. The key slot is slidably connected to the limiting slot block 12, and the axial position between the I-shaped cable barrel 13 and the rotating shaft 11 is limited by the mutual cooperation between the limiting slot block 12 and the key slot.

[0022] A top plate 14 is mounted on the inner side of the upper end of the fixed vertical plate 5. A threaded barrel 16 is internally threaded and threadedly connected to a screw 17. The lower end of the screw 17 is fixedly connected to the rotating block 15. A rotating seat 20 is fixedly connected to the middle position above the guide block 7. The rotating seat 20 has a stepped cavity within it, which is rotatably connected to the rotating block 15. The screw 17 passes through a through hole above the rotating seat 20 and connects to the rotating block 15. When the crank 18 drives the screw 17 to rotate, the rotating block 15 can rotate within the rotating seat 20 and drive the guide block 7 to rise and fall.

[0023] The utility model is simple to operate on site, safe and reliable, greatly reduces the labor intensity of construction, realizes rapid loading of cable reels, makes cable retraction and extension convenient and quick, improves production efficiency by 50%, and has strong practicality and operability.
