Description

Technical Field

[0001] This utility model relates to the field of power pole technology, specifically a rapid fixing structure for power poles that are connected segment by segment using flanges. Background Technology

[0002] Power poles are an important component of power transmission systems, widely used in transmission lines, communication lines, and other fields. Traditionally, power poles are installed by connecting sections one by one to meet the needs of different heights and scenarios. However, existing power pole connection structures have some problems, mainly in the following aspects:

[0003] In traditional installation processes, power poles are typically connected using fasteners such as bolts. Due to the large size of the poles and the need for installation at heights, significant time and effort are required to align the flanges and tighten each bolt individually. This method is not only inefficient but also prone to errors due to inaccurate alignment or uneven bolt tightening, leading to instability at the pole connections and even tilting. Furthermore, the need for multiple people to work together further increases the difficulty and cost of the installation. The lack of effective pre-alignment devices in traditional connection methods makes the connections unstable due to excessive gaps between flanges or inaccurate alignment, further reducing the reliability of the entire power pole structure. Utility Model Content

[0004] The purpose of this invention is to provide a quick-fixing structure for power poles that are connected segment by segment using flanges, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A quick-fixing structure for power poles connected segment by segment by flanges includes multiple power poles stacked sequentially from bottom to top. A first flange is provided at the bottom end of each power pole, and a second flange is provided at the top end of each power pole. The first flange and the second flange abut against each other.

[0007] Multiple fixing components are provided between the first flange and the second flange. These fixing components are evenly distributed along the circumference. When the two power poles are stacked and installed, the multiple fixing components can pre-position the first flange and the second flange and keep them in a tight fit, preventing the two power poles from tilting. Then, by adjusting the multiple fixing components, the first flange and the second flange can be stably connected.

[0008] As a further embodiment of this utility model:

[0009] The fixing component includes a positioning cylinder, a positioning seat, and a nut. The outer wall of the positioning cylinder is provided with an external thread, and the positioning cylinder is connected to the vertical thread of the first flange through the external thread.

[0010] The second flange has an installation groove, the positioning seat is located in the installation groove, and the nut cooperates with the positioning seat to fix the positioning seat in the installation groove.

[0011] As a further improvement of this utility model:

[0012] A central shaft is vertically slidably arranged inside the positioning cylinder, and a pressing head is provided at the top of the central shaft;

[0013] A spring is fitted on the outer wall of the shaft rod, and the two ends of the spring abut against the inner walls of the pressing head and the positioning cylinder, respectively, so as to drive the pressing head to drive the shaft rod to always have an upward tendency.

[0014] As a further improvement of this utility model:

[0015] The bottom of the shaft is provided with an annular receiving groove, and the top and bottom of the annular receiving groove are both set as inclined surfaces;

[0016] The side wall of the positioning cylinder has two symmetrical through slots, and each through slot has a ball that is movably fitted into it. The two balls are also fitted into the annular receiving slot.

[0017] As a further improvement of this utility model:

[0018] The distance between the center of the through groove and the shaft is greater than the distance between the center of gravity of the ball and the shaft, so that the ball always tends to move closer to the shaft.

[0019] The central shaft always tends to move upward, and the bottom slope of the annular receiving groove always pushes the ball, causing the ball to protrude outward from the side wall of the positioning cylinder through the through groove.

[0020] As a further improvement of this utility model:

[0021] The inner wall of the positioning seat is provided with an annular limiting ramp. When the positioning cylinder is inserted into the positioning seat, the ball will abut against the annular limiting ramp, so that the positioning cylinder is confined within the positioning seat.

[0022] As a further improvement of this utility model:

[0023] The inner wall of the positioning seat is provided with internal threads, and the top of the positioning cylinder is provided with a hexagonal block;

[0024] When the ball comes into contact with the annular limiting ramp, the external thread on the positioning cylinder corresponds to the internal thread. At this time, by turning the hexagonal block with a tool, the positioning cylinder will rotate. At the same time, the external thread and the internal thread will gradually mesh. During this process, the ball will separate from the annular limiting ramp.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] By setting multiple fixing components evenly distributed along the circumference between flange No. 1 and flange No. 2, pre-positioning can be quickly achieved when the two power poles are stacked and installed, and they can be kept in a tight fit. This effectively avoids tilting between the two power poles during installation, thereby improving the stability and reliability of the installation, reducing the subsequent adjustment time caused by installation errors, and improving installation efficiency.

[0027] The fixing components not only achieve pre-positioning, but also allow for further adjustment to achieve a stable connection between flange No. 1 and flange No. 2. This dual function ensures a more robust connection between the flanges, effectively resisting the influence of external factors (such as wind and vibration) on the connection of the power pole, enhancing the stability and reliability of the entire power pole structure, and extending its service life.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0035] Furthermore, the elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0036] Please see Figures 1-5 In this embodiment of the utility model, a quick fixing structure for power poles connected segment by segment by flanges includes multiple power poles 1 stacked sequentially from bottom to top. A first flange 2 is provided at the bottom end of the power pole 1, and a second flange 3 is provided at the top end of the power pole 1. The first flange 2 and the second flange 3 abut against each other.

[0037] Multiple fixing components are provided between the first flange 2 and the second flange 3. The multiple fixing components are evenly distributed along the circumference. When the two power poles 1 are stacked and installed, the multiple fixing components can pre-position the first flange 2 and the second flange 3 and keep them in a tight fit to prevent the two power poles 1 from tilting. Then, by adjusting the multiple fixing components, the first flange 2 and the second flange 3 can be stably connected.

[0038] In this scheme, each power pole 1 is provided with a No. 1 flange 2 at the bottom and a No. 2 flange 3 at the top. During the installation process, the No. 2 flange 3 of the next section of the power pole 1 is abutted against the No. 1 flange 2 of the previous section of the power pole 1 to form a stacked structure. At this time, the contact surface between the two flanges needs to be kept flat to ensure the stability of the subsequent connection.

[0039] Multiple fixing components are installed between flange 2 and flange 3. These fixing components are evenly distributed along the circumference of the flanges, and their number and distribution position are determined according to the diameter of the power pole 1 and the design requirements. When the flanges of the two power poles 1 come into contact with each other, the multiple fixing components begin to function. The design of the fixing components enables them to quickly pre-position flange 2 and flange 3, ensuring that the two flanges remain tightly fitted in the initial state. This pre-positioning function can effectively prevent the two power poles 1 from tilting during installation, thus providing a foundation for subsequent stable connection.

[0040] After the pre-positioning is completed, multiple fixing components are further adjusted to make the connection between flange 2 and flange 3 more secure. After the adjustment is completed, a stable connection is formed between flange 2 and flange 3. This connection can not only bear the weight of the power pole 1 itself, but also resist the influence of external factors such as wind and vibration on the connection, ensuring the stability of the power pole 1 throughout the entire use process.

[0041] Following the steps described above, multiple power poles 1 are stacked and connected sequentially. After each connection is completed, the next section is installed until the entire power pole structure reaches the required total height.

[0042] As a further embodiment of this utility model, the fixing component includes a positioning cylinder 4, a positioning seat 5, and a nut 6. The outer wall of the positioning cylinder 4 is provided with an external thread 401, and the positioning cylinder 4 is vertically threaded to the first flange 2 through the external thread 401.

[0043] The second flange 3 has an installation groove 301, the positioning seat 5 is located in the installation groove 301, and the nut 6 cooperates with the positioning seat 5 to fix the positioning seat 5 in the installation groove 301.

[0044] In this embodiment, firstly, the positioning cylinder 4 is installed on the first flange 2. The outer wall of the positioning cylinder 4 is provided with an external thread 401. By rotating the positioning cylinder 4, its external thread 401 is vertically threaded to the threaded hole on the first flange 2, thereby firmly fixing the positioning cylinder 4 on the first flange 2. This threaded connection method not only provides reliable fixing force, but also facilitates subsequent disassembly and maintenance.

[0045] The positioning seat 5 is placed in the mounting groove 301 of the second flange 3. The mounting groove 301 is pre-opened on the second flange 3 to accommodate the positioning seat 5. The shape and size of the positioning seat 5 match the mounting groove 301 to ensure that it can be stably embedded therein.

[0046] After the positioning seat 5 is installed in place, use the nut 6 to cooperate with the positioning seat 5. By tightening the nut 6 with the positioning seat 5, the positioning seat 5 is firmly fixed in the mounting groove 301.

[0047] As a further embodiment of this utility model, a central shaft 7 is vertically slidably arranged inside the positioning cylinder 4, and a pressing head 8 is provided on the top of the central shaft 7;

[0048] A spring 9 is sleeved on the outer wall of the shaft rod 7. The two ends of the spring 9 abut against the inner walls of the pressing head 8 and the positioning cylinder 4, respectively, so as to drive the pressing head 8 to drive the shaft rod 7 to always have an upward tendency.

[0049] The bottom of the shaft rod 7 is provided with an annular receiving groove 701, and the top and bottom of the annular receiving groove 701 are both set as inclined surfaces;

[0050] The side wall of the positioning cylinder 4 has two symmetrical through grooves 402, and each of the two through grooves 402 has a ball 10 movably fitted in it, and the two balls 10 are also respectively fitted in the annular receiving groove 701.

[0051] The distance between the center of the through groove 402 and the shaft 7 is greater than the distance between the center of gravity of the ball 10 and the shaft 7, so that the ball 10 always tends to move closer to the shaft 7.

[0052] The shaft 7 always tends to move upward, and the bottom slope of the annular receiving groove 701 always pushes the ball 10, so that the ball 10 protrudes outward from the side wall of the positioning cylinder 4 through the through groove 402.

[0053] The inner wall of the positioning seat 5 is provided with an annular limiting ramp 501. When the positioning cylinder 4 is inserted into the positioning seat 5, the ball 10 will abut against the annular limiting ramp 501 so that the positioning cylinder 4 is limited to the positioning seat 5.

[0054] The inner wall of the positioning seat 5 is provided with an internal thread 502, and the top of the positioning cylinder 4 is provided with a hexagonal block 11.

[0055] When the ball 10 abuts against the annular limiting ramp 501, the external thread 401 on the positioning cylinder 4 corresponds to the internal thread 502. At this time, by turning the hexagonal block 11 with the help of a tool, the positioning cylinder 4 will rotate accordingly. At the same time, the external thread 401 and the internal thread 502 will gradually mesh. During this process, the ball 10 will separate from the annular limiting ramp 501.

[0056] In this embodiment, initially, a vertically sliding shaft 7 is installed inside the positioning cylinder 4, and a pressing head 8 is installed at the top of the shaft 7. A spring 9 is sleeved on the outer wall of the shaft 7, and the two ends of the spring 9 abut against the pressing head 8 and the inner wall of the positioning cylinder 4, respectively. This design ensures that the pressing head 8 always has an upward tendency under the action of the spring 9, thereby driving the shaft 7 to move upward as well. An annular receiving groove 701 is provided at the bottom of the shaft 7. The top and bottom of the annular receiving groove 701 are both inclined surfaces. This inclined surface design will play a key role in the subsequent process.

[0057] The side wall of the positioning cylinder 4 has two symmetrical through grooves 402. A ball 10 is movably fitted in the through groove 402. The ball 10 is also fitted in the annular receiving groove 701. The distance between the center of the through groove 402 and the shaft 7 is greater than the distance between the center of gravity of the ball 10 and the shaft 7. This design makes the ball 10 tend to move closer to the shaft 7 under its own weight and structural design.

[0058] Since the shaft rod 7 always tends to move upward under the action of the spring 9, the bottom slope of the annular receiving groove 701 will always push the ball 10. This pushing action causes the ball 10 to protrude outward from the side wall of the positioning cylinder 4 through the through groove 402.

[0059] When the positioning cylinder 4 is inserted into the positioning seat 5, the ball 10 abuts against the annular limiting ramp 501 on the inner wall of the positioning seat 5. The design of the annular limiting ramp 501 limits the ball 10 during the insertion process, thereby firmly limiting the positioning cylinder 4 in the positioning seat 5.

[0060] The inner wall of the positioning seat 5 is provided with an internal thread 502, and the top of the positioning cylinder 4 is provided with a hexagonal block 11. When the ball 10 abuts against the annular limiting ramp 501, the external thread 401 on the positioning cylinder 4 corresponds to the internal thread 502. At this time, by using a tool such as a wrench to turn the hexagonal block 11, the positioning cylinder 4 will rotate. As the positioning cylinder 4 rotates, the external thread 401 and the internal thread 502 gradually mesh.

[0061] During the engagement of the external thread 401 and the internal thread 502, the ball 10 separates from the annular limiting ramp 501, allowing the positioning cylinder 4 to be smoothly screwed into the positioning seat 5, thus completing the final fixation.

[0062] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0063] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
