Description

Technical Field

[0001] This utility model relates to the field of power transmission line support technology, and in particular to a support structure for power transmission lines. Background Technology

[0002] In the field of power transmission line erection and maintenance, the support structure is a core component ensuring the stable and safe operation of the line. Its performance and installation efficiency directly affect the reliability, economy, and safety of the power transmission system. With the growth of electricity demand and the increasing complexity of power grid construction, the requirements for support structures are becoming increasingly stringent.

[0003] Existing power transmission line support devices have significant shortcomings. Taking the device with publication number CN222016150U as an example, although it has solved the problem of insufficient support cables to some extent and reduced space occupation, construction time and cost, the splicing operation is cumbersome and not fast or convenient enough.

[0004] In power transmission line construction, time is crucial to efficiency, cost, and safety. Complex and time-consuming splicing operations can extend the construction period, delay project progress, and increase safety risks for construction workers due to working at heights. In emergency repairs or special environments, inconvenient splicing can prevent the timely erection of supporting structures, leading to large-scale power outages and significant losses.

[0005] Therefore, developing a transmission line support structure that is quick and easy to assemble, can effectively support multiple cables, improve installation efficiency, and reduce costs and risks is of great practical significance. Utility Model Content

[0006] The problem this utility model aims to solve is to provide a support structure for power transmission lines that is quick and easy to assemble, can effectively support multiple power transmission line cables, improves installation efficiency, and reduces construction costs and risks.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a support structure for power transmission lines, including a mounting plate, a first threaded rod fixedly connected to the front of the mounting plate, a hexagonal threaded cylinder threadedly connected to the outer surface of the first threaded rod, a strip-shaped square tube rotatably connected to the end of the hexagonal threaded cylinder away from the first threaded rod, a first slider slidably connected to the inner wall of the strip-shaped square tube, a strip-shaped square box fixedly connected to the front of the first slider, a lead screw rotatably connected to the inside of the strip-shaped square box, a second slider slidably connected to the inner wall of the strip-shaped square box, the inside of the second slider being threadedly connected to the lead screw, a quick-assembly mechanism provided on the front of the second slider, the quick-assembly mechanism including a first splicing frame, a second splicing frame and a first slot, the first slot being opened inside the second slider, a locking plate fixedly connected to the upper surface of the first splicing frame, the locking plate engaging with the first slot, and a second slot being opened inside the first splicing frame.

[0008] Preferably, in the above-mentioned support structure for power transmission lines, the outer surface of the lead screw is threaded with a second nut, and the top end of the lead screw is fixedly connected with a hexagonal screw block.

[0009] Preferably, in the above-mentioned support structure for power transmission lines, the strip-shaped square tube has a first groove and a second groove inside, and the first slider is slidably connected to the inner wall of the second groove.

[0010] Preferably, in the above-described support structure for power transmission lines, the upper surface of the first slider is fixedly connected to a second threaded rod, which extends to the top of the second groove, and the outer surface of the second threaded rod is threadedly connected to a first nut.

[0011] Preferably, in the above-mentioned support structure for power transmission lines, the outer surface of the first threaded rod is threaded with a third nut, the front of the mounting plate is fixedly connected with a cylindrical rod, and the interior of the mounting plate has four mounting holes.

[0012] Preferably, in the above-mentioned support structure for power transmission lines, the inner wall of the cylindrical rod is slidably connected with a nail-shaped slide rod, and the end of the nail-shaped slide rod away from the cylindrical rod is fixedly connected to the back of the strip-shaped square tube.

[0013] The advantages and beneficial effects of this utility model are:

[0014] I. This utility model, by setting up a quick-assembly mechanism, including a first splicing frame, a second splicing frame, a clamping plate, and a through-designed slot, realizes the function of rapid splicing of power transmission line support structures. In actual operation, by inserting the clamping plate of the first splicing frame into the first slot of the second slider, and inserting the clamping plate of the second splicing frame into the second slot of the first splicing frame, the splicing operation can be completed quickly, significantly reducing splicing time and construction complexity. Compared with the prior art, the splicing method of this utility model does not require additional tools, is easy to operate, can effectively improve installation efficiency, reduce construction costs and high-altitude operation risks, and is especially suitable for emergency repairs and rapid construction needs in complex environments.

[0015] Second, this utility model achieves multi-directional flexible adjustment of the support structure by setting up a hexagonal threaded cylinder, a first slider, a lead screw, and a corresponding nut. Specifically, the extension length of the strip-shaped square cylinder can be adjusted by rotating the hexagonal threaded cylinder, the left and right positions of the quick-assembly mechanism can be adjusted by sliding the first slider and tightening the first nut, and the vertical height of the quick-assembly mechanism can be adjusted by rotating the lead screw and tightening the second nut.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] like Figures 1 to 4 As shown, a support structure for a power transmission line includes a mounting plate 1. A first threaded rod 2 is fixedly connected to the front of the mounting plate 1. A hexagonal threaded cylinder 3 is threadedly connected to the outer surface of the first threaded rod 2. A strip-shaped square tube 4 is rotatably connected to the end of the hexagonal threaded cylinder 3 away from the first threaded rod 2. Four mounting holes 18 are provided inside the mounting plate 1. A third nut 15 is threadedly connected to the outer surface of the first threaded rod 2. A cylindrical rod 16 is fixedly connected to the front of the mounting plate 1. A nail-shaped slide rod 17 is slidably connected to the inner wall of the cylindrical rod 16. The end of the nail-shaped slide rod 17 away from the cylindrical rod 16 is fixedly connected to the back of the strip-shaped square tube 4.

[0023] The function of the third nut 15 is to fix the hexagonal threaded cylinder 3. There are two cylindrical rods 16 and two nail-shaped slide rods 17, which are set between the strip square tube 4 and the mounting plate 1.

[0024] A first slider 5 is slidably connected to the inner wall of the strip-shaped square tube 4. A first groove 13 and a second groove 14 are provided inside the strip-shaped square tube 4. The first slider 5 is slidably connected to the inner wall of the second groove 14. A second threaded rod 8 is fixedly connected to the upper surface of the first slider 5 and extends to the top of the second groove 14. A first nut 9 is threadedly connected to the outer surface of the second threaded rod 8.

[0025] Two of each are provided: the first slider 5, the second threaded rod 8, and the first nut 9, all of which are located inside the strip-shaped square tube 4.

[0026] The front of the first slider 5 is fixedly connected to a strip-shaped box 6. The inside of the strip-shaped box 6 is rotatably connected to a lead screw 10. The inner wall of the strip-shaped box 6 is slidably connected to a second slider 12. The inside of the second slider 12 is threadedly connected to the lead screw 10. The outer surface of the lead screw 10 is threadedly connected to a second nut 11. The top of the lead screw 10 is fixedly connected to a hexagonal screw block.

[0027] There are two of each of the strip-shaped box 6, the lead screw 10, the second nut 11, and the second slider 12, and their specific positions correspond to the two first sliders 5 respectively.

[0028] The front of the second slider 12 is provided with a quick-assembly mechanism 7. The quick-assembly mechanism 7 includes a first splicing frame 701, a second splicing frame 702 and a first slot 703. The first slot 703 is opened inside the second slider 12. A card plate 704 is fixedly connected to the upper surface of the first splicing frame 701. The card plate 704 is engaged with the first slot 703. A second slot 705 is opened inside the first splicing frame 701.

[0029] The quick-assembly mechanism 7 has two locations, each corresponding to one of the two second sliders 12. The second splicing frame 702 also has a locking plate 704 and a second locking slot 705. The second splicing frame 702 engages with the second locking slot 705 inside the first splicing frame 701 via the locking plate 704, thus achieving rapid splicing. Simultaneously, the first locking slot 703 and the second locking slot 705 are designed to be through-hole, allowing debris or dust particles to fall directly out during splicing, preventing engagement failure.

[0030] Mounting plate 1 is the foundation, with four mounting holes 18 for secure connection to supports such as utility poles. A first threaded rod 2, fixed to the front, engages with a hexagonal threaded cylinder 3. Rotating the hexagonal threaded cylinder 3 adjusts the extension length of the rotatably connected strip-shaped square tube 4, thereby adjusting the extension length of the two sets of splicing frames. A cylindrical rod 16 and a nail-shaped sliding rod 17 provide auxiliary guidance and support. A first slider 5 inside the strip-shaped square tube 4, fixed to a first nut 9 by a second threaded rod 8, can slide along the first and second sliding grooves 13 and 14, allowing for left-right position adjustment of the quick-assembly mechanism 7. Inside the strip-shaped square box 6 connected to the first slider 5, a screw rod 10, a second slider 12, and a second nut 11 work together to adjust the vertical height of the quick-assembly mechanism 7. The quick-assembly mechanism 7 consists of a first splicing frame 701 and a second splicing frame 702, achieving rapid assembly via a clamping plate 704 and two slots.

[0031] like Figures 1 to 4 As shown, in some practical applications, the mounting plate 1 is first fixed to a support such as a utility pole through the mounting hole 18. To adjust the extension length of the quick-assembly mechanism 7, rotate the hexagonal threaded cylinder 3 to move the strip-shaped square tube 4 along the first threaded rod 2, and tighten the third nut 15 after it is in place. To adjust the left and right position of the quick-assembly mechanism 7, loosen the first nut 9, slide the first slider 5, and then tighten the first nut 9. When adjusting the vertical height of the quick-assembly mechanism 7, rotate the hexagonal screw block at the top of the screw 10 to move the second slider 12 up and down within the strip-shaped square box 6, and then tighten the second nut 11. During splicing, the clamping plate 704 of the first splicing frame 701 is inserted into the first slot 703 of the second slider 12, and then the clamping plate 704 of the second splicing frame 702 is inserted into the second slot 705 of the first splicing frame 701 to achieve rapid splicing and build a structure that supports multiple power transmission line cables.

[0032] Working principle: The supporting structure for power transmission lines of this utility model mainly revolves around the coordinated operation of various components to achieve effective support and flexible splicing and adjustment of power transmission line cables.

[0033] Mounting plate 1 serves as the fundamental connecting component of the entire support structure. Its front side is fixedly connected to a first threaded rod 2, which is threadedly connected to a hexagonal threaded cylinder 3. The end of the hexagonal threaded cylinder 3 furthest from the first threaded rod 2 is rotatably connected to a strip-shaped square tube 4. Furthermore, the cylindrical rod 16 and the nail-shaped slide rod 17, both fixedly connected to the front side of mounting plate 1, are in sliding engagement (two of each are provided between the strip-shaped square tube 4 and mounting plate 1, serving as auxiliary support and limiting the movement direction of the strip-shaped square tube 4). When the hexagonal threaded cylinder 3 is rotated, guided by the cylindrical rod 16 and the nail-shaped slide rod 17, the strip-shaped square tube 4 can move along the axial direction of the first threaded rod 2, thereby adjusting the length of the strip-shaped square tube 4 extending forward relative to mounting plate 1, and consequently adjusting the extension length of the two sets of splicing frames. After the extension length is adjusted to the appropriate position, the third nut 15 is tightened to fix the hexagonal threaded cylinder 3, stabilizing the relative position of the strip-shaped square tube 4 and mounting plate 1. Meanwhile, the four mounting holes 18 inside the mounting plate 1 are used to fix the mounting plate 1 to the required installation position, such as a utility pole or other support.

[0034] A first slider 5 is slidably connected to the inner wall of the strip-shaped square tube 4. The first slider 5 slides in conjunction with a first groove 13 and a second groove 14 opened inside the strip-shaped square tube 4. A second threaded rod 8, fixedly connected to the upper surface of the first slider 5, extends to the top of the second groove 14 and is fixed by a first nut 9. When it is necessary to adjust the left and right positions of the two quick-assembly mechanisms 7, loosen the first nut 9, slide the first slider 5 to the appropriate position inside the strip-shaped square tube 4, and then tighten the first nut 9 to fix the first slider 5, thereby realizing the adjustment of the left and right positions of the quick-assembly mechanism 7. There are two first sliders 5, two second threaded rods 8, and one first nut 9, all located inside the strip-shaped square tube 4, which can be used to adjust the left and right positions of the corresponding quick-assembly mechanisms 7 respectively.

[0035] A lead screw 10 is rotatably connected inside a strip-shaped box 6 that is fixedly connected to the front of the first slider 5. A second slider 12, which is slidably connected to the inner wall of the strip-shaped box 6, is threadedly connected to the lead screw 10. A second nut 11 is threadedly connected to the outer surface of the lead screw 10, and a hexagonal locking block is fixedly connected to the top of the lead screw 10. When it is necessary to adjust the vertical height of the quick-assembly mechanism 7, the lead screw 10 is rotated by rotating the hexagonal locking block. Since the second slider 12 is threadedly connected to the lead screw 10 and slides inside the strip-shaped box 6, the rotation of the lead screw 10 allows the second slider 12 to move up and down inside the strip-shaped box 6, thereby adjusting the vertical height of the quick-assembly mechanism 7. After adjustment, the second nut 11 is tightened to fix the position of the lead screw 10 and prevent the height of the quick-assembly mechanism 7 from changing due to external force. There are two strip-shaped boxes 6, two lead screws 10, two second nuts 11, and two second sliders 12, each corresponding to one of the two first sliders 5, and each can independently adjust the vertical height of its corresponding quick-assembly mechanism 7.

[0036] The first slot 703 is located inside the second slider 12. A locking plate 704, fixedly connected to the upper surface of the first splicing frame 701, engages with the first slot 703, thus connecting the first splicing frame 701 and the second slider 12. A second slot 705 is located inside the first splicing frame 701, and a locking plate 704 is also provided on the second splicing frame 702. The second splicing frame 702 engages with the second slot 705 inside the first splicing frame 701 via the locking plate 704, thereby achieving rapid splicing. Furthermore, the first slot 703 and the second slot 705 are designed to be continuous, allowing debris or dust particles to fall directly out during the splicing process, preventing splicing failure due to debris accumulation. Throughout the entire support structure construction process, the operation of the aforementioned components enables rapid and convenient splicing, effectively supporting multiple power transmission line cables, improving installation efficiency, and reducing construction costs and risks.
