Description
Technical Field
[0001] This utility model relates to the field of power facility technology, specifically to a combined structure of a tapered cement pole and a crossarm. Background Technology
[0002] In power transmission systems, tapered concrete poles are widely used due to their good stability and economy. Furthermore, the crossarm, as an important component for installing insulators and fixing conductors, is crucial in its combination with tapered concrete poles.
[0003] Currently, most composite structures of tapered cement poles and crossarms are connected by clamps or single bolts. Under harsh natural conditions such as long-term exposure to wind, sun, rain, and strong winds, these single fastening points are prone to loosening, leading to a decrease in the reliability of the connection between the crossarm and the tapered cement pole and posing safety hazards. Secondly, the installation positions of insulators on most crossarms are usually fixed and cannot be flexibly adjusted. However, different voltage levels of power lines have different requirements for the safety distance between insulators, and the fixed crossarm structure cannot adapt to these changes, resulting in poor versatility. Therefore, a composite structure of tapered cement poles and crossarms is proposed to solve the problems mentioned above. Utility Model Content
[0004] To address the aforementioned technical problems, a combined structure of a tapered cement pole and a crossarm is provided. This technical solution solves the problem mentioned in the background art: currently, most combined structures of tapered cement poles and crossarms are connected by clamps or single bolts for direct fixation. However, under harsh natural conditions such as long-term exposure to wind, sun, rain, and strong winds, a single fastening point is prone to loosening, leading to a decrease in the reliability of the connection between the crossarm and the tapered cement pole, posing a safety hazard. Secondly, the installation position of insulators on most crossarms is usually fixed and cannot be flexibly adjusted. In power lines with different voltage levels, there are different requirements for the safety distance between insulators, and the fixed crossarm structure cannot adapt to this change, resulting in poor versatility.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A combined structure of a tapered concrete pole and a crossarm includes a tapered concrete pole body, a mounting assembly, a fixing assembly, and a crossarm assembly. The mounting assembly is installed at the upper end of the tapered concrete pole body, the fixing assembly is installed at the upper end of the mounting assembly, and the crossarm assembly is installed at the rear of the fixing assembly. The fixing assembly includes two connecting blocks. Fixing plates are provided on both the front and rear sides of the two connecting blocks. The rear fixing plate is fixedly installed between the two connecting blocks. Limiting grooves are formed on the inner sides of both connecting blocks. Rectangular openings are formed through the upper and lower ends of each limiting groove. An adjusting block is slidably connected inside the limiting groove. Limiting blocks are fixedly connected to the upper and lower ends of each adjusting block. The limiting blocks are slidably connected inside the rectangular openings. The adjusting blocks and limiting blocks are fastened to the limiting grooves and rectangular openings by fasteners. The inner sides of the two adjusting blocks are fixedly connected to the left and right ends of the rear fixing plate, respectively. Anti-slip pads and two positioning rods are installed on opposite sides of the two fixing plates. The two fixing plates are fastened together by fasteners. The crossarm assembly includes a support block, with limit openings through the upper left and right sides of the support block. Rectangular openings are through the front and rear ends of the limit openings, and several adjustment blocks are slidably connected inside the limit openings.
[0006] Preferably, the upper part of the second adjusting block extends above the support block, and an insulator is installed at the upper end of the second adjusting block.
[0007] Preferably, both ends of the adjusting block two are fixedly connected to the limiting block two, the limiting block two is slidably connected to the inside of the limiting opening, and the adjusting block two and the limiting block two are fastened to the inside of the limiting opening and the rectangular opening two by the fastener three.
[0008] Preferably, a fixing block is fixedly connected to both the left and right sides of the upper end of the support block, and a limit rod is fixedly installed between the two fixing blocks. The outer surface of the limit rod is slidably connected to the upper part of the adjustment block two.
[0009] Preferably, the installation assembly includes a first installation rod, the lower end of which is fixedly connected to the upper end of the tapered cement pole body, and a second installation rod fixedly connected to the upper end of the first installation rod, the second installation rod having two symmetrically positioned grooves on its outer surface.

[0012] The advantages of this utility model compared with the prior art are: This utility model uses fastener two in the fixing component to clamp two fixing plates with anti-slip pads onto mounting rod two in the mounting component, forming the first layer of fastening. The positioning rod on the fixing plate is precisely inserted into the positioning groove opened on the outer surface of mounting rod two, thereby preventing the crossarm assembly from rotating or slipping in the vertical direction after being subjected to force, which is the second layer of fastening. Finally, fastener one is used for final limiting, so that the crossarm assembly and fixing component can be firmly installed on the tapered cement pole body.
[0013] Secondly, the adjusting block 2 can slide within the limiting opening of the support block, thereby driving the insulator to move. Through the cooperation of the limiting block 2 and the rectangular opening 2, and the fastening of the fastener 3, the adjusting block 2 can be fastened to a suitable position on the support block, thereby adjusting the distance between two adjacent insulators.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. This description is intended to disclose the present invention so that those skilled in the art can implement it. Furthermore, the embodiments described are merely examples, and the present invention can be implemented in other ways different from those described herein. Example 1
[0017] Reference Figures 1-7 As shown, a combined structure of a tapered cement pole and a crossarm includes a tapered cement pole body 100, an installation component 200, a fixing component 300, and a crossarm component 400. The installation component 200 is installed at the upper end of the tapered cement pole body 100, the fixing component 300 is installed at the upper end of the installation component 200, and the crossarm component 400 is installed at the rear side of the fixing component 300.
[0018] Reference Figure 4 and Figure 5 As shown, the fixing component 300 includes two connecting blocks 301. Fixing plates 307 are provided on both the front and rear sides between the two connecting blocks 301. The rear fixing plate 307 is fixedly installed between the two connecting blocks 301. Limiting grooves 302 are formed on the inner sides of both connecting blocks 301. Rectangular openings 303 are formed through the upper and lower ends of the limiting grooves 302. Adjusting blocks 304 are slidably connected inside the limiting grooves 302. Limiting blocks 304 are fixedly connected to the upper and lower ends of the adjusting blocks 304. Block 1 305 and limit block 1 305 are slidably connected inside rectangular opening 1 303. Adjusting block 1 304 and limit block 1 305 are fastened to the limit groove 302 and rectangular opening 1 303 by fastener 1 306. The inner sides of the two adjusting blocks 1 304 are respectively fixedly connected to the left and right ends of the rear fixing plate 307. Anti-slip pads 308 and two positioning rods 309 are installed on the opposite side of the two fixing plates 307. The two fixing plates 307 are fastened together by fastener 2 310.
[0019] Specifically, fastener 1 306, fastener 2 310 and fastener 3 407 are all composed of fastening bolts, nuts and washers. Furthermore, adjusting block 1 304, limiting block 1 305, the two fixing plates 307, and adjusting block 2 404 and limiting block 2 406 all have matching threaded grooves inside. In addition, when the fastening bolt shows a slight tendency to loosen, the washer can compensate for the gap through its own elastic deformation and continue to maintain a certain pressure to prevent the fastening bolt from loosening further.
[0020] Reference Figure 2As shown, the installation assembly 200 includes a first installation rod 201, the lower end of which is fixedly connected to the upper end of the tapered cement rod body 100, and a second installation rod 202 is fixedly connected to the upper end of the first installation rod 201. Two positioning grooves 203 are symmetrically opened on the outer surface of the second installation rod 202.
[0021] Specifically, the diameter of mounting rod 202 is smaller than that of mounting rod 201, and the height of the two fixing plates 307 is the same as that of mounting rod 202. This allows the two fixing plates 307 to be quickly guided to the correct position, preventing tilting during initial installation. Furthermore, the fixing block 408 at the upper end of mounting rod 202 can also prevent the fixing component 300 from moving downwards. Example 2
[0022] Based on the above embodiment one, referring to Figure 3 , Figure 6 and Figure 7 As shown, the crossarm assembly 400 includes a support block 401. Limiting openings 402 are provided on both the left and right sides of the upper end of the support block 401. Rectangular openings 403 are provided on both the front and rear ends of the limiting openings 402. Several adjusting blocks 404 are slidably connected inside the limiting openings 402. The upper part of the adjusting blocks 404 extends above the support block 401. An insulator 405 is installed on the upper end of the adjusting blocks 404. Limiting blocks 406 are fixedly connected to both the front and rear ends of the adjusting blocks 404. The limiting blocks 406 are slidably connected inside the limiting openings 402. The adjusting blocks 404 and the limiting blocks 406 are fastened to the limiting openings 402 and the rectangular openings 403 by fasteners 407. Fixing blocks 408 are fixedly connected to both the left and right sides of the upper end of the support block 401. A limiting rod 409 is fixedly installed between two fixing blocks 408. The outer surface of the limiting rod 409 is slidably connected to the upper part of the adjusting blocks 404.
[0023] A connecting plate 500 is fixedly connected to the rear end of the rear fixing plate 307. The rear end of the connecting plate 500 is fixedly connected to the front end of the support block 401. Reinforcing plates 600 are fixedly connected to both the left and right sides of the front end of the support block 401. The other end of the reinforcing plate 600 is fixedly connected to the outer side of the two connecting blocks 301.
[0024] Specifically, the upper part of the adjusting block 404 slides on the outer surface of the limiting rod 409. The limiting rod 409 plays a role in limiting and guiding, ensuring the stability and accuracy of the adjusting block 404 during the sliding process, and making the adjustment of the spacing of the insulators 405 more convenient.
[0025] The usage process of this utility model: In use, move the adjusting block 304 to the front end of the inner side of the limiting groove 302 to maximize the distance between the two fixing plates 307. Then, insert the fixing assembly 300 from the upper end of the tapered cement pole body 100 onto the outer surface of the mounting assembly 200. Next, place the rear fixing plate 307 on the upper surface of the mounting rod 201. Then, make the anti-slip pad 308 at the inner end of the fixing plate 307 fit against the outer surface of the mounting rod 202. At this time, the two positioning rods 309 at the front end of the rear fixing plate 307 are inserted into the interior of the mounting rod 202. Then, push the front fixing plate. 307, so that the adjusting blocks 304 at both ends of the front fixing plate 307 slide inside the limiting groove 302 until the anti-slip pad 308 at the rear end of the front fixing plate 307 is in contact with the outer surface of the mounting rod 201 and the positioning rod 309 is inserted into the interior of the mounting rod 202. Then, the two fixing plates 307 are fastened by the fastener 310. At this time, the adjusting block 304 is fastened inside the limiting groove 302 by the fastener 305, so that the crossbeam assembly 400 can be installed on the tapered cement pole body 100 by the fixing assembly 300.
[0026] After installation, depending on the voltage level of the power line, the distance between two adjacent adjusting blocks 404 is adjusted by pushing adjusting block 2 404 to move inside the limiting opening 402. After adjustment, adjusting block 2 404 is fastened inside the limiting opening 402 by fastener 3 407. Finally, insulator 405 is installed on the upper end of adjusting block 2 404, thereby completing the adjustment of the distance between two adjacent insulators 405.
