Description

Technical Field

[0001] This utility model relates to the technical field of narrow-base angle steel towers, specifically a narrow-base angle steel tower with adjustable cable sag. Background Technology

[0002] In the field of power transmission, narrow-base angle steel towers serve as crucial infrastructure for supporting and erecting cables, and their performance is vital to the stable operation of power systems. With the continuous development of the power industry and the increasing diversification of power transmission demands, the installation environment and requirements for cables are becoming increasingly complex.

[0003] Traditional narrow-base angle steel towers are not reliable in limiting and fixing cables. During the operation of cables, they are affected by external factors such as wind and temperature changes, which will cause the cables to sway and shift. If the angle steel tower does not firmly limit the cables, the cable sag will change, which may lead to problems such as cable loosening and wear. In severe cases, it may cause power transmission interruption or even safety accidents. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a narrow-base angle steel tower with adjustable cable sag, including a mounting bracket 1 and an adjusting component 2. The outer wall of the adjusting component 2 is fixedly connected to the outer wall of the mounting bracket 1, and a limiting component 3 is rotatably connected to the outer wall of the adjusting component 2. The limiting component 3 includes a limiting frame 31, with sliding blocks 33 slidably connected to the inner walls on both sides of the limiting frame 31. The outer wall of the sliding block 33 is threadedly connected to a lead rod 32 through a threaded ring 34, and the inner wall of the threaded ring 34 is threadedly connected to the outer wall of the lead rod 32. A locking bolt 36 is slidably connected to the inner wall of the limiting frame 31.

[0021] The outer wall of the locking bolt 36 is threaded with a locking nut, and the outer wall of the locking nut is pressed and fixed to the outer wall of the limiting frame 31. The outer wall of the limiting frame 31 is fixedly connected with a fixing seat 35. The inner wall of the fixing seat 35 is rotatably connected to the outer wall of the lead screw 32. The outer wall of the threaded ring 34 is fixedly connected to the outer wall of the sliding block 33.

[0022] The adjusting assembly 2 includes a fixed plate 21. Fixed wheels 22 are rotatably connected to the inner walls on both sides of the fixed plate 21. Sliding wheels 26 are slidably connected to the outer walls of the fixed wheels 22 via limiting posts 23. The outer walls of the limiting posts 23 are slidably connected to the inner walls of the sliding wheels 26. A top spring 25 is fixedly connected to the outer walls of the limiting posts 23. During the sliding of the sliding wheels 26, the top spring 25 will be compressed or stretched, generating corresponding elastic force. A limiting ring 27 is engaged with the inner walls of the limiting posts 23 via a slot. The limiting ring 27 effectively limits the sliding range of the sliding wheels 26, ensuring that it moves within a reasonable range. A pressure ring 24 is fixedly connected to one end of the top spring 25 near the fixed wheels 22. The outer walls of the limiting ring 27 are slidably connected to the outer walls of the sliding wheels 26. The outer walls of the pressure ring 24 are pressed and fixed to the outer walls of the limiting ring 27. The outer walls of the limiting posts 23 are fixedly connected to the outer walls of the fixed wheels 22.

[0023] This narrow-base angle steel tower with adjustable cable sag mainly consists of a mounting bracket 1, an adjustment component 2, and a limiting component 3. These parts work together to achieve precise adjustment of the cable sag, ensuring that the cable maintains a suitable sag on the narrow-base angle steel tower to adapt to different working environments and power transmission requirements. Its specific working principle is as follows:

[0024] First, the adjustment assembly 2 is the key part for realizing cable sag adjustment. The adjustment assembly 2 includes components such as a fixed plate 21, a fixed wheel 22, a limiting post 23, a top spring 25, a pressure ring 24, a sliding wheel 26, and a limiting ring 27. The fixed wheel 22 is rotatably connected to the inner walls on both sides of the fixed plate 21, and the fixed wheel 22 provides the rotation basis for subsequent adjustment operations.

[0025] When it is necessary to adjust the position between the fixed wheel 22 and the sliding wheel 26, an external force is applied to the sliding wheel 26, causing it to slide along the limiting post 23. The outer wall of the limiting post 23 is fixedly connected to the outer wall of the fixed wheel 22, serving as support and guidance. At the same time, a top spring 25 is fixedly connected to the outer wall of the limiting post 23. A pressure ring 24 is fixedly connected to one end of the top spring 25 near the fixed wheel 22. During the sliding process of the sliding wheel 26, the top spring 25 will be compressed or stretched, generating corresponding elastic force.

[0026] The elastic force of the top spring 25 can play a buffering and stabilizing role during the adjustment process, preventing the sliding wheel 26 from moving unstablely due to sudden changes in external force. In addition, the inner wall of the limiting post 23 is engaged with the limiting ring 27 through a slot, and the outer wall of the limiting ring 27 is slidably connected to the outer wall of the sliding wheel 26. The limiting ring 27 effectively limits the sliding range of the sliding wheel 26, ensuring that it moves within a reasonable range.

[0027] When the sliding wheel 26 moves to the appropriate position, the outer wall of the pressure ring 24 presses against the outer wall of the limiting ring 27 to fix it, thereby stably fixing the sliding wheel 26 in that position and completing the position adjustment of the adjusting component 2.

[0028] Next, the limiting component 3 comes into play to limit and fix the cable to ensure that the adjusted sag is maintained. The limiting component 3 includes a limiting frame 31, a lead screw 32, a sliding block 33, a threaded ring 34, a fixing seat 35, a locking bolt 36, and a locking nut.

[0029] The outer wall of the limiting frame 31 is rotatably connected to the adjusting component 2. Sliding blocks 33 are slidably connected to the inner walls on both sides of the limiting frame 31. The lead screw 32 is rotatably connected to the limiting frame 31 through the fixed seat 35. The inner wall of the fixed seat 35 is rotatably connected to the outer wall of the lead screw 32, so that the lead screw 32 can rotate flexibly within the limiting frame 31. The outer wall of the sliding block 33 is threadedly connected to the lead screw 32 through the threaded ring 34. The inner wall of the threaded ring 34 is threadedly connected to the outer wall of the lead screw 32, and the outer wall of the threaded ring 34 is fixedly connected to the outer wall of the sliding block 33.

[0030] When it is necessary to change the verticality of the cable, rotate the lead screw 32. Due to the threaded connection, the rotation of the lead screw 32 will drive the sliding block 33 to move along the axial direction of the lead screw 32 within the limit frame 31. By adjusting the position of the sliding block 33, which is also equipped with a fixed wheel 22 with the same structure as the sliding wheel 26, it will contact the cable and clamp the cable.

[0031] Then, the locking bolt 36 is passed through the corresponding holes on the limiting frame 31 and the sliding block 33, and the locking bolt 36 is tightened with the locking nut so that the outer wall of the locking nut is pressed and fixed with the outer wall of the limiting frame 31, thereby firmly fixing the sliding block 33 in the current position and realizing reliable limiting of the cable.

[0032] Through the coordinated operation of adjustment component 2 and limiting component 3, this narrow-base angle steel tower with adjustable cable sag can flexibly adjust the cable sag according to actual needs. The limiting component 3 ensures that the cable operates stably under the adjusted sag state, which improves the installation and use effect of the cable on the narrow-base angle steel tower and ensures the safety and stability of power transmission.
