Description

Technical Field

[0001] This utility model relates to the field of steel pipe pole technology, specifically a power steel pipe pole structure. Background Technology

[0002] Steel pipe poles are poles made of steel pipes. They are widely used in overhead transmission lines, which are the main power transmission method adopted since the development of the power industry. Overhead lines connect power plants, substations and load points in different locations to form power grids of various voltage levels.

[0003] In existing technologies, power steel pipe poles are too long to be easily transported, so they are assembled in sections. Most steel pipe poles are assembled by bolting together flanges. After installation, due to the long length of the steel pipe pole, if the middle part of the steel pipe pole cannot be well supported, it is prone to bending deformation due to its own weight. After long-term placement, the bending degree of the pole will increase, which will lead to serious risks during operation. Therefore, a new power steel pipe pole structure is proposed. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a power steel pipe pole structure to solve the technical problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power steel pipe pole structure, including a base, a fixing rod connected to the top of the base, a fixing component provided at the top of the fixing rod, a plug-in rod provided at the top of the fixing component, and a support component provided on the curved outer wall of the fixing rod;

[0006] The fixing component includes a bushing connected to the upper end of the curved outer wall of the fixing rod. The outer wall of the curved surface of the bushing has a circumferential array of multiple sets of connecting blocks. A rotating shaft is rotatably connected inside the connecting blocks.

The ring is fixed to the bushing by bolts, and four sets of insert plates are fixed on the curved outer wall of the ring.

[0007] The support assembly includes a fixing sleeve connected to the lower end of the curved outer wall of the fixing rod. Eight sets of horizontal plates are fixed to the curved outer wall of the fixing sleeve. The eight sets of horizontal plates are divided into four pairs. A base rod is fixed between each pair of horizontal plates. A connecting column is rotatably connected to the surface of the base rod. A support rod is rotatably connected inside the connecting column. Four sets of connecting pipes are fixed inside the fixing rod. A telescopic shaft is slidably connected to the inner wall of one end of each of the four sets of connecting pipes, and a pressing rod is slidably connected to the inner wall of the other end of the connecting pipe. A spring is sleeved on the surface of the pressing rod.

[0008] As a preferred technical solution, the connecting block is provided in eight groups, and the eight groups of connecting blocks are divided into four pairs. The outer wall of the plug rod is provided with a slot for matching the L-shaped rod, and the plug plate is located directly above each pair of connecting blocks.

[0009] As a preferred technical solution, a limiting groove is formed on the inner wall of the connecting block, and a limiting plate fixed to the rotating shaft is provided inside the limiting groove. The limiting plate is slidably connected to the connecting block through the limiting groove.

[0014] In summary, the present invention has the following main advantages:

[0015] This utility model uses a plug-in rod inserted into the bushing to embed the positioning shaft into the positioning groove, completing the initial connection between the fixed rod and the plug-in rod. The fixed rod and the plug-in rod are then fixed together with bolts. The L-shaped rod fits into the groove on the curved outer wall of the plug-in rod, providing support. Simultaneously, the end of the telescopic shaft abuts against one side of the L-shaped rod, further supporting it. Finally, by rotating the support rod, it is inserted into the ground, providing support for the fixed rod.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] A type of power steel pipe pole structure, such as Figure 1-6 As shown, it includes a base 100, a fixing rod 110 connected to the top of the base 100, a fixing component 200 provided at the top of the fixing rod 110, a plug-in rod 120 provided at the top of the fixing component 200, and a support component 300 provided on the curved outer wall of the fixing rod 110.

[0028] The fixing component 200 includes a bushing 210 connected to the upper end of the curved outer wall of the fixing rod 110. The outer wall of the curved surface of the bushing 210 has a circumferential array of multiple sets of connecting blocks 220. A rotating shaft 230 is rotatably connected inside the connecting block 220. An L-shaped rod 240 is fixed on the surface of the rotating shaft 230. A ring 250 is fixed at the lower end of the curved outer wall of the plug rod 120. The ring 250 is fixed to the bushing 210 by bolts 251. Four sets of insert plates 260 are fixed on the curved outer wall of the ring 250.

[0029] The support assembly 300 includes a fixing sleeve 310 connected to the lower end of the curved outer wall of the fixing rod 110. Eight sets of horizontal plates 320 are fixed to the curved outer wall of the fixing sleeve 310. The eight sets of horizontal plates 320 are divided into four pairs. A base rod 330 is fixed between each pair of horizontal plates 320. A connecting column 340 is rotatably connected to the surface of the base rod 330. A support rod 350 is rotatably connected inside the connecting column 340. Four sets of connecting pipes 360 are fixed inside the fixing rod 110. A telescopic shaft 370 is slidably connected to the inner wall of one end of the four sets of connecting pipes 360, and a pressing rod 380 is slidably connected to the inner wall of the other end of the connecting pipe 360. A spring 390 is sleeved on the surface of the pressing rod 380.

[0030] After fixing the base 100 to the ground, the plug rod 120 is inserted into the bushing 210, so that the positioning shaft 270 is embedded in the positioning groove 271, and the ring 250 is fitted with the top of the bushing 210, completing the initial connection between the fixing rod 110 and the plug rod 120. The fixing rod 110 and the plug rod 120 are then fixed with bolts 251. Simultaneously, when the ring 250 moves downwards to connect with the bushing 210, it drives the insert plate 260 to move synchronously, causing the bottom of the insert plate 260 to abut against the L-shaped rod 240. This causes the L-shaped rod 240 to rotate through the rotating shaft 230 until it fits into the slot 241 on the curved outer wall of the plug rod 120, thus supporting the plug rod 120. At this point, the connecting posts 3 around the fixing rod 110 are... 40 is opened by rotating the base rod 330, which compresses the compression rod 380 by the connecting column 340. The compression rod 380 slides inside the connecting tube 360 ​​to stretch the spring 390 and compress the gas inside the connecting tube 360. Under the action of air pressure, the telescopic shaft 370 extends out from inside the connecting tube 360, and then the end of the telescopic shaft 370 abuts against one side of the L-shaped rod 240, thus supporting the L-shaped rod 240. Finally, by rotating the support rod 350, the support rod 350 is inserted into the ground to support the fixed rod 110. By supporting the fixed rod 110 and the insertion rod 120 respectively, axial displacement between the fixed rod 110 and the insertion rod 120 can be effectively prevented, avoiding pole swaying caused by wind or external forces, and effectively improving the overall stability of the power steel pipe pole.

[0031] Please refer to this carefully. Figure 1 , Figures 3 to 5 The connecting block 220 has eight sets, which are divided into four pairs. The outer curved wall of the plug rod 120 has a slot 241 for matching the L-shaped rod 240. The plug plate 260 is located directly above each pair of connecting blocks 220. The inner wall of the connecting block 220 has a limiting groove 232. The limiting groove 232 has a limiting plate 231 fixed to the rotating shaft 230 inside. The limiting plate 231 is slidably connected to the connecting block 220 through the limiting groove 232.

[0032] The cooperation between the limiting plate 231 and the limiting groove 232 can effectively prevent the L-shaped rod 240 from rotating when it is not being squeezed.

[0033] Please refer to this carefully. Figure 4 The bottom of the ring 250 has four sets of positioning shafts 270 in a circumferential array. The top of the bushing 210 is provided with a positioning groove 271 that matches the positioning shaft 270. The ring 250 is provided with a cover plate 280 that is slidably connected to the outer wall of the curved surface of the plug rod 120.

[0034] The positioning shaft 270 and the positioning groove 271 work together to enable the plug rod 120 to be quickly fixed by the bolt 251 when connected to the fixing rod 110. The cover plate 280 can effectively cover the top of the bolt 251 to prevent the bolt 251 from rusting over time.

[0035] Please refer to this carefully. Figure 2 and Figure 6 The end of the extrusion rod 380 away from the connecting tube 360 ​​is opposite to the side of the L-shaped rod 240, and the other end of the extrusion rod 380 is opposite to the side of the connecting column 340. The spring 390 is fixed to one end of the inner wall of the connecting tube 360.

[0036] The compression rod 380 can serve as a support for the L-shaped rod 240, and the spring 390 can better reset the compression rod 380.

[0037] In use, after fixing the base 100 to the ground, the plug rod 120 is inserted into the bushing 210, so that the positioning shaft 270 is embedded in the positioning groove 271, completing the initial connection between the fixing rod 110 and the plug rod 120. Then, the fixing rod 110 and the plug rod 120 are fixed with bolts 251. The L-shaped rod 240 will fit into the slot 241 on the curved outer wall of the plug rod 120, achieving the effect of supporting the plug rod 120. At the same time, the end of the telescopic shaft 370 abuts against one side of the L-shaped rod 240. The device supports the L-shaped pole 240. Finally, by rotating the support rod 350, the support rod 350 is inserted into the ground, thus supporting the fixed pole 110. By supporting the fixed pole 110 and the insertion rod 120 respectively, axial displacement between the fixed pole 110 and the insertion rod 120 can be effectively prevented, avoiding pole swaying caused by wind or external forces, and effectively improving the overall stability of the power steel pipe pole. The parts not involved in this device are the same as or can be implemented using existing technologies.
