[0002] Low-voltage cables are electrical cables used to transmit electricity. They are usually used in low-voltage power systems. They are mainly used to transmit electricity from substations to end users or industrial equipment. Low-voltage cables usually use insulating materials to wrap conductors to ensure safe and reliable power transmission. Low-voltage cables can use different conductor materials and insulating materials according to different requirements to meet different power transmission needs. In the selection and installation of low-voltage cables, factors such as the electrical performance, heat resistance, weather resistance, and surrounding environment of the cables need to be considered. During installation, workers usually need to climb up the poles to install them.

[0003] The shortcomings of the existing low-voltage cable aerial installation device: the current equipment usually adopts the traditional design of fixing the mounting frame on the surface of the utility pole, and installing the cable through the reserved holes. However, this design limits the flexibility and adjustability of the cable layout. Once the mounting frame encounters the situation where two cables in different directions need to be installed, multiple support frames need to be installed to meet the needs. In addition, the fixed position and hole position setting of the current device require a certain amount of experience in the installation process, and fine-tuning cannot be performed after installation. Therefore, there are problems of layout restrictions and inconvenience in adjustment. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5 As shown, the utility model provides a low-voltage cable high-altitude erection device, comprising two symmetrically distributed locking rings 1 and a movable ring 2 assembled on the inner wall of the locking ring 1, and a position adjustment structure 3 slidably connected to the inner wall of the movable ring 2, and a fixed structure 4 is installed on one side of the position adjustment structure 3;

[0022] The position adjustment structure 3 includes a movable block 31 and a screw rod 32 fixedly mounted at the bottom of the movable block 31, and a locking ring 33 fixedly mounted on the outer wall of the screw rod 32. A threaded hole is provided on the inner wall of the movable block 31, and the screw rod 32 is threadedly connected to the threaded hole. The bottom end of the screw rod 32 passes through the locking ring 33 and extends to the bottom of the locking ring 33. A screw sleeve 35 is provided below the locking ring 33. The screw sleeve 35 is threadedly connected to the outer wall of the screw rod 32, and the top surface of the screw sleeve 35 is tightly fitted with the bottom surface of the movable ring 2.

[0023] The fixed structure 4 includes a supporting cross plate 41 assembled on one side of the movable block 31, an annular frame 42 installed on the side of the supporting cross plate 41 away from the movable block 31, and a threaded rod 43 located inside the annular frame 42. One end of the threaded rod 43 extends into the inside of the annular frame 42 and a limit block 44 is fixedly installed through a bearing.

[0024] The above scheme is adopted: through the design of the position adjustment structure 3, the device can be installed through the locking ring 1. At this time, the screw sleeve 35 is loosened to allow the screw rod 32 to rotate. By rotating the threaded rod 43, the locking ring 33 will be driven to move downward so that it contacts and engages with the rack. At this time, the movable block 31 is located above the rack and can slide in the through groove 22, which can drive the fixed structure 4 to move to the required position. When the required position is reached, the locking ring 33 is moved up and engaged with the rack by rotating the screw rod 32 in the opposite direction, and then the position of the movable block 31 and the fixed structure 4 is fixed by the locking screw sleeve 35, thereby achieving a quick adjustment effect.

[0025] like Figures 1 to 5 As shown, the inner wall of the movable ring 2 is provided with an annular groove 21, the inner wall of the annular groove 21 is provided with a through groove 22, the outer wall of the movable block 31 is slidably connected to the inner wall of the through groove 22 and the top surface of the movable block 31 is in contact with the inner top wall of the annular groove 21, the two locking rings 1 are tightly fitted and fixed by screws.

[0026] The above solution is adopted: the surface of the movable ring 2 in contact with the electric pole is sprayed with anti-slip paint, and the two movable rings 2 are fixed and installed by screws, so that the two movable rings 2 are tightly attached and fixed to the outer wall of the electric pole.

[0027] like Figures 1 to 5 As shown, two annular frames 42 are provided and are symmetrically distributed on both sides of the front side of the supporting horizontal plate 41 .

[0028] With the above solution, the two annular frames 42 are symmetrically distributed, so that the cables will not be bent, and the cables can be fixed by the limit blocks 44 when passing through the annular frames 42 .

[0029] like Figures 1 to 5 As shown, a rack matched with the locking ring 33 is provided at the edge of the inner wall of the through groove 22 , and the rack is located below the movable block 31 .

[0030] By adopting the above solution, the rack can be meshed and locked with the locking ring 33. When a cross wind blows toward the supporting cross plate 41, the movable block 31 will not be easily changed under the condition of being doubly fixed.

[0031] The working principle and use process of this utility model:

[0032] First, the staff needs to fix the two locking rings 1 to the surface of the pole with screws, and then adjust the position of the fixed structure 4 according to the cable arrangement position, and then loosen the screw sleeve 35 to make the screw rod 32 rotatable, and rotate the threaded rod 43 to drive the locking ring 33 to move down, so that it contacts and engages with the rack. At this time, the movable block 31 is located above the rack and can slide in the through groove 22, which can drive the fixed structure 4 to move to the required position. When it reaches the required position, the locking ring 33 is moved up and engaged with the rack by rotating the screw rod 32 in the opposite direction, and then the position of the movable block 31 and the fixed structure 4 is fixed by the locking screw sleeve 35. At this time, the cable is passed through the annular frame 42, and the limit block 44 is driven downward to abut against the cable by rotating the threaded rod 43 to achieve the effect of fixing the cable position. At this point, the entire workflow is completed.
