Description

Technical Field

[0001] This utility model relates to the field of cement pole technology, and in particular to a self-supporting cement pole. Background Technology

[0002] Cement poles are columnar structural components made primarily of concrete, with an internal steel reinforcement framework for load-bearing support. They are formed through casting and curing in molds. They are widely used in power transmission, communication signal installation, road lighting, and farmland irrigation, serving as the foundation for supporting cables, lighting fixtures, equipment, and other external components. Thanks to the excellent durability, corrosion resistance, and load-bearing capacity of concrete, cement poles can operate stably for extended periods in complex outdoor environments (such as high-temperature, low-temperature, humid, and windy areas), making them an indispensable product in infrastructure construction.

[0003] In related technologies, cement poles are mainly produced using a monolithic casting process. This involves placing a steel reinforcement cage into a customized cylindrical mold, pouring concrete, and then performing centrifugal molding and steam curing to create a complete pole in one step. However, in actual use, cement poles are quite heavy, requiring high load-bearing capacity from on-site hoisting equipment. Hoisting and transportation are difficult and costly, and they are easily constrained by construction site conditions. Furthermore, cement poles are prone to cracking due to external environmental factors. Since cement poles are buried underground, replacing them is a complex process, increasing the labor intensity and operational risks for workers. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to propose a self-supporting cement pole that can connect two spliced ​​poles into one unit. By assembling, the manpower and time costs of on-site installation are reduced, and the length can be adjusted according to the actual use scenario, thus improving practicality. At the same time, the spliced ​​poles can be pulled by a pulling component to enhance the stability of the connection.

[0006] To achieve the above objectives, the first aspect of this utility model provides a self-supporting cement pole, comprising: a pole body, an upper connecting mechanism, and a lower connecting mechanism, wherein the upper connecting mechanism includes a first connecting disc, a first outer tube, a second connecting disc, and a slider assembly, wherein the first connecting disc is disposed at the top of the pole body; the first outer tube is disposed on the pole body via the first connecting disc; the second connecting disc is disposed on the first outer tube; and the slider assembly is disposed on the inner wall of the first outer tube; the lower connecting mechanism includes a third connecting disc, a second outer tube, a fourth connecting disc, a insertion tube, and a pulling assembly, wherein the third connecting disc is disposed at the bottom of the pole body; the second outer tube is disposed on the pole body via the third connecting disc; the fourth connecting disc is disposed on the second outer tube; the insertion tube is disposed inside the second outer tube; and the pulling assembly is disposed on the third connecting disc.

[0007] In addition, the self-supporting cement pole proposed above according to this utility model may also have the following additional technical features: Specifically, the second connecting plate and the fourth connecting plate correspond to each other, and both the second connecting plate and the fourth connecting plate have connecting holes.

[0008] Specifically, the bottom end of the insertion tube extends through the second outer tube, and the extended end of the insertion tube corresponds to the inner diameter of the first outer tube, and a guide groove is provided on the insertion tube.

[0009] Specifically, the traction assembly includes a first fixing member, a second fixing member, and a pull rod, wherein the first fixing member is disposed on the side wall of the third connecting plate; the second fixing member is disposed on the side wall of the first connecting plate, and both the first fixing member and the second fixing member have through holes; the pull rod is disposed in the through hole of the second fixing member.

[0010] Specifically, the bottom end of the pull rod passes through the through hole on the first fixing member and extends out, and two elastic members are symmetrically arranged at the bottom end of the pull rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The self-supporting cement pole of the present invention aligns the connecting holes on the second connecting plate and the fourth connecting plate, allowing bolts to pass through the connecting holes and fasten the second connecting plate and the fourth connecting plate together, thereby connecting the two spliced ​​poles into one unit. The assembly reduces the manpower and time costs of on-site installation, and the length can be adjusted according to the actual use scenario, improving practicality. At the same time, during installation, the elastic element at the bottom of the tie rod passes through the through hole on the second fixing member, connecting the tie rod to the second fixing member, thereby pulling the spliced ​​poles and enhancing the overall stability of the connection part.

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] A self-supporting cement pole according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0017] like Figures 1-5 As shown, a self-supporting cement pole according to an embodiment of the present invention may include: pole body 1, upper connecting mechanism 2 and lower connecting mechanism 3.

[0018] It should be noted that the rod 1 described in this embodiment has a hollow structure, which reduces the weight of the rod 1 itself and facilitates transportation and on-site hoisting operations.

[0019] The upper connecting mechanism 2 includes a first connecting plate 21, a first outer tube 22, a second connecting plate 23, and a slider assembly 24. The first connecting plate 21 is located at the top of the rod 1, the first outer tube 22 is located on the rod 1 via the first connecting plate 21, the second connecting plate 23 is located on the first outer tube 22, and the slider assembly 24 is located on the inner wall of the first outer tube 22. The lower connecting mechanism 3 includes a third connecting plate 31, a second outer tube 32, a fourth connecting plate 33, a insertion tube 34, and a pulling assembly 35. The third connecting plate 31 is located at the bottom of the rod 1, the second outer tube 32 is located on the rod 1 via the third connecting plate 31, the fourth connecting plate 33 is located on the second outer tube 32, the insertion tube 34 is located inside the second outer tube 32, and the pulling assembly 35 is located on the third connecting plate 31.

[0020] It should be noted that the first connecting plate 21 and the third connecting plate 31 described in this embodiment are connected to the pole body 1 by an integrated casting method, which avoids loosening at the connecting joint and improves the wind resistance and overturning resistance of the cement pole.

[0021] Specifically, during installation, workers can use hoisting equipment to lift one of the rods 1, aligning the fourth connecting plate 33 at its bottom with the second connecting plate 23 at the top of the other rod 1, so that the second connecting plate 23 and the fourth connecting plate 33 fit together. At this time, the fourth connecting plate 33 is fastened to the top end face of the second connecting plate 23 with bolts, thus fastening the two rods 1 together.

[0022] Meanwhile, during the alignment of the second connecting plate 23 and the fourth connecting plate 33, the insertion pipe 34 will be inserted into the first outer pipe 22, thereby correcting any slight misalignment that may occur during the docking process. Furthermore, when the insertion pipe 34 is inserted into the first outer pipe 22, it can help bear the lateral wind load on the pole body 1, thus improving the stability of the cement pole.

[0023] Furthermore, once the bolts are tightened, workers can apply a limiting tension to the rod 1 using the traction assembly 35 to further ensure the stability of the rod 1 connection.

[0024] In one embodiment of this utility model, such as Figure 2 As shown, the second connecting plate 23 and the fourth connecting plate 33 correspond to each other, and both the second connecting plate 23 and the fourth connecting plate 33 are provided with a connecting hole 4.

[0025] It is understood that multiple connecting holes 4 are provided at equal intervals in this embodiment. The diameter of the connecting holes 4 is adapted to the specifications of the connecting bolts to ensure that the bolts can penetrate the second connecting plate 23 and the fourth connecting plate 33, thereby improving the assembly efficiency and connection stability of the rod body 1.

[0026] Specifically, during installation, the connecting holes 4 on the second connecting plate 23 and the fourth connecting plate 33 are aligned one by one, and then the bolts are passed through the second connecting plate 23 and the fourth connecting plate 33 in sequence, and tightened with nuts.

[0027] In one embodiment of this utility model, such as Figure 3 As shown, the bottom end of the insertion tube 34 extends through the second outer tube 32, and the extended end of the insertion tube 34 corresponds to the inner diameter of the first outer tube 22. A guide groove 341 is provided on the insertion tube 34.

[0028] It should be noted that the size of the guide groove 341 described in this embodiment matches the slider group 24, and the guide groove 341 is inserted into the tube 34 at equal intervals along the axial direction. Each guide groove 341 corresponds to the slider group 24 one-to-one, so that the slider group 24 can be embedded in the guide groove 341 to form a sliding fit.

[0029] Specifically, as the insertion tube 34 is gradually inserted into the first outer tube 22, the slider group 24 on the inner wall of the first outer tube 22 will correspond to the guide groove 341 on the insertion tube 34, so that the slider group 24 slides along the guide groove 341, thereby providing guidance for the subsequent docking of the connecting hole 4. Furthermore, the cooperation between the slider group 24 and the guide groove 341 can enhance the stability of the connection and avoid the risk of loosening or breaking at the connection.

[0030] In one embodiment of this utility model, such as Figure 3 and Figure 5 As shown, the traction assembly 35 includes a first fixing member 351, a second fixing member 352, and a pull rod 353. The first fixing member 351 is disposed on the side wall of the third connecting plate 31, the second fixing member 352 is disposed on the side wall of the first connecting plate 21, and both the first fixing member 351 and the second fixing member 352 are provided with through holes 5. The pull rod 353 is disposed in the through hole 5 of the second fixing member 352.

[0031] It should be noted that the pull rod 353 described in this embodiment is connected to the second fixing member 352 by a thread, so that the operator can adjust the length of the pull rod 353 extending out of the second fixing member 352 by rotating the pull rod 353, thereby achieving fine adjustment of the tension.

[0032] Specifically, when the operator rotates the pull rod 353, the pull rod 353 moves up and down along the internal thread of the second fixing member 352 via the thread. When the pull rod 353 extends downward out of the second fixing member 352, the connection between the bottom end of the pull rod 353 and the first fixing member 351 gradually moves away, causing the tension to decrease accordingly. When the pull rod 353 retracts upward, the connection between the bottom end of the pull rod 353 and the first fixing member 351 gradually tightens, and the tension increases accordingly. By adjusting the tension of the pull rod 353, tension adjustment is achieved, thereby improving the stability of the connection.

[0033] In one embodiment of this utility model, such as Figure 5 As shown, the bottom end of the pull rod 353 passes through the through hole 5 on the first fixing member 351 and extends out, and two elastic members 3531 are symmetrically arranged at the bottom end of the pull rod 353.

[0034] It should be noted that the elastic element 3531 described in this embodiment has an arc surface at its bottom end. With the guidance of the arc surface, the elastic element 3531 can pass through the through hole 5 on the second fixing element 352, ensuring convenient installation.

[0035] Specifically, when the elastic element 3531 passes through the through hole 5 of the second fixing element 352, the arc surface at the bottom of the elastic element 3531 slides against the wall surface of the through hole 5, so that the elastic element 3531 passes through the through hole 5 on the second fixing element 352 that is compatible with the pull rod 353. After the elastic element 3531 passes through, it can engage with the second fixing element 352 to form a stable support.

[0036] In summary, this utility model of a self-supporting cement pole, by aligning the connecting holes on the second and fourth connecting plates, allows bolts to pass through the connecting holes and securely connect the second and fourth connecting plates, thereby connecting two spliced ​​pole bodies into one. This assembly reduces the manpower and time costs of on-site installation, and the length can be adjusted according to actual usage scenarios, improving practicality. Furthermore, during installation, the elastic element at the bottom of the tie rod passes through the through hole on the second fixing component, connecting the tie rod to the second fixing component, thus pulling the spliced ​​pole body and enhancing the overall stability of the connection.
