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] There are generally four methods for cable laying: direct burial, duct laying, cable trench or tunnel laying, and cable tray laying. The construction process for direct burial is as follows: First, excavate a trench. If the bottom of the trench is rocky or has hard debris, lay a 100mm thick layer of soft soil or fine sand. Then, lay the cable directly at the bottom of the trench, followed by another 100mm thick layer of soft soil or fine sand, and finally cover it with a concrete protective slab or bricks. Direct burial offers advantages such as low investment, convenient construction, and good heat dissipation. It is suitable for situations where there are no underground obstacles, the soil does not contain severely corrosive acids, alkalis, or salts, and the number of cables is relatively small.

[0003] Currently, when laying cables, the method is mostly to pull the cable to drive the winding drum on the cable laying vehicle to rotate, thereby pulling out the cable as needed and laying it in the cable trench. This pulling method can easily damage the cable, and the installation and removal of the winding drum is also quite troublesome. Utility Model Content

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1 to 5 The cable laying device shown includes:

[0026] U-shaped frame 1, with two connecting plates 2 fixed at the bottom end of U-shaped frame 1, and a winding drum 3 between the two connecting plates 2. A limiting plate 4 is fixed at both ends of the winding drum 3.

[0027] Two rotating columns 5 are rotatably connected to two connecting plates 2 via bearings. A square groove 6 is provided at the end of the rotating column 5 near the take-up drum 3. A square rod 7 is provided inside the square groove 6. A plug block 8 is fixedly connected to one end of the square rod 7. The two plug blocks 8 are respectively inserted into the two ends of the take-up drum 3. The cross-section of the plug block 8 is frustum-shaped. A threaded rod 9 is provided inside the square groove 6. One end of the threaded rod 9 passes through the end of the rotating column 5 away from the take-up drum 3 and is rotatably connected to the rotating column 5. A threaded groove 10 is provided in the middle of the square rod 7. The other end of the threaded rod 9 extends into the threaded groove 10 and is threadedly connected to the threaded groove 10. A rotating block 11 is fixedly provided at one end of the threaded rod 9.

[0028] An electric hydraulic rod 12 is fixedly connected to each of the four corners of the bottom of the U-shaped frame 1. The four electric hydraulic rods 12 are respectively located on both sides of the two connecting plates 2. A base plate 13 is fixedly connected to the bottom of the two electric hydraulic rods 12 located on both sides of the connecting plate 2. A matching power supply 14 is fixedly installed at the top of the U-shaped frame 1. The matching power supply 14 is electrically connected to the four electric hydraulic rods 12. Four brake wheels 15 are fixedly installed at the bottom of the two base plates 13. A traction frame 20 is fixedly installed on the side of the U-shaped frame 1 away from the L-shaped connecting block 16.

[0029] Each of the two base plates 13 has an L-shaped connecting block 16 fixed at one end. A redirecting roller 17 is provided between the two L-shaped connecting blocks 16. A rotating shaft 18 is fixed at both ends of the redirecting roller 17. The two rotating shafts 18 are rotatably connected to the two L-shaped connecting blocks 16. A limit groove 19 is opened in the middle of the outer end of the redirecting roller 17.

[0030] Connect the power equipment to the traction frame 20 so that the four brake wheels 15 are placed on both sides of the cable trench. Then, pass one end of the cable through the bottom of the limiting groove 19 and fix one end of the cable inside the cable trench. The power equipment drives the laying device to move. At this time, the cable will be released from the outer end of the winding drum 3. The redirecting roller 17 and the limiting groove 19 will limit the cable, so that the cable can be laid along the cable trench.

[0031] After the cable is laid out, hold the rotating column 5 with one hand, and then rotate the rotating block 11. The rotating block 11 drives the threaded rod 9 to rotate. Since the threaded rod 9 is threadedly connected to the threaded groove 10, the square rod 7 moves into the square groove 6 as the threaded rod 9 rotates. The square rod 7 drives the plug block 8 away from the end of the take-up drum 3, so that the take-up drum 3 and the limiting plate 4 can be removed. Start the four electric hydraulic rods 12. The electric hydraulic rods 12 drive the U-shaped frame 1 and the connecting plate 2 to move downwards. Place the new take-up drum 3 and the cable between the two connecting plates 2 at the bottom of the U-shaped frame 1. Adjust the height of the two connecting plates 2 and the plug block 8 on them so that the plug block 8 is located at the end of the take-up drum 3. Rotate the rotating block 11 in the opposite direction. The square rod 7 will bring the plug block 8 into the end of the new take-up drum 3. Then the four electric hydraulic rods 12 will drive the take-up drum 3 and the cable to move upwards. This completes the replacement and installation of the take-up drum 3.

[0032] This invention uses a power device to move the laying device to release the cable, avoiding cable pulling damage. Two adjustable plug-in blocks 8 are engaged inside both ends of the take-up drum 3, and four electric hydraulic rods 12 move the plug-in blocks 8 up and down, making it convenient and quick to install, disassemble, and replace the take-up drum 3. This makes the installation and disassembly of the take-up drum 3 more convenient and labor-saving. This embodiment specifically solves the problem that in the prior art, when laying cables, most of the time the cable is pulled to drive the take-up drum on the cable laying vehicle to rotate, and then the cable is pulled out as needed and laid in the cable trench. Such pulling can easily damage the cable, and the installation and disassembly of the take-up drum is also relatively troublesome.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
