Description

Technical Field

[0001] This utility model relates to the field of power transmission line pile technology, specifically to an earthquake-resistant power transmission line pile. Background Technology

[0002] Transmission line piles are the foundation structures used in power grid construction to support the towers of overhead transmission lines. They primarily bear the conductor load and transfer it to deep, stable ground. Typically precast reinforced concrete, they are corrosion-resistant and have high compressive strength, making them suitable for various geological conditions such as plains, mountains, and swamps. Their burial depth is designed according to the geological bearing capacity, and the stability of the tower is ensured through pile side friction and end resistance, preventing settlement or toppling. As a crucial support for the "lifeline" of power transmission, their construction quality directly affects line safety and transmission efficiency. With the development of intelligent power grids, new composite material piles and intelligent monitoring technologies are being gradually applied, driving transmission lines to extend to higher voltage levels and more complex environments.

[0003] Chinese patent CN213449734U discloses a wind- and earthquake-resistant power transmission line pole for BeiDou satellite navigation. The pole includes a reinforcing block with a base underneath. A groove is formed on the upper surface of the base, and equidistantly arranged first springs are fixedly connected to the inner bottom wall of the groove. A first sliding plate is located inside the groove, with the top of each first spring fixedly connected to the bottom surface of the first sliding plate. The upper surface of the first sliding plate is fixedly connected to the bottom surface of the reinforcing block. A recess is formed on the upper surface of the reinforcing block, and symmetrical second springs are fixedly connected to the inner bottom wall of the recess. The tops of two second springs are jointly fixedly connected to a second sliding plate. This wind- and earthquake-resistant power transmission line pole for BeiDou satellite navigation effectively resists wind and earthquakes, preventing slippage caused by vibration and improving the stability of the power transmission line pole when supporting data transmission lines.

[0004] The aforementioned patent document describes a power transmission line pole that uses a telescopic plate added to its bottom to support the pole. The cable is then fixed to the top of the pole using a bracket. However, when the cable is exposed to wind, it sways, making the bracket prone to bending or breakage. Therefore, a seismic-resistant power transmission line pile is proposed. Utility Model Content

[0005] To address the aforementioned issues, a seismic-resistant transmission line pile is provided. A ball head fixed to the top of the boom is installed inside a spherical mounting groove. An anti-disengagement sleeve is then fixed to the bottom of the connector, ensuring the ball head remains within the groove. This effectively prevents the ball head from detaching. The cable is then secured to the bottom of the boom using a fixing assembly to prevent cable detachment. When the cable sways, it moves the boom via the fixing assembly, causing the boom to rotate along the spherical mounting groove through the ball head. This effectively prevents bending or breakage of the support assembly, solving the problem of easy bending or breakage in support assemblies.

[0006] To address the existing technical problems, this application provides an earthquake-resistant transmission line pile, including a pile, a damper installed at the bottom of the pile for supporting it, a cantilever installed at the top of the pile, and an adjustable support assembly installed on the cantilever. The support assembly includes a fixing rod longitudinally fixed to one end of the cantilever, a connecting seat at the bottom end of the fixing rod, and a spherical mounting groove at the bottom end of the connecting seat.

[0007] The bracket assembly also includes a hanger rod, the top of which is fixed with a ball head that can be adapted to the spherical mounting groove;

[0008] The outside of the boom is provided with an anti-disengagement sleeve that can be threaded into the spherical mounting groove. The anti-disengagement sleeve is used to prevent the ball head from falling out of the spherical mounting groove.

[0009] The bottom end of the fixing rod is provided with a fixing component for fixing the cable.

[0010] As one technical solution of this application, the outer side of the connecting seat is provided with a nut that can rotate along its central axis. The nut can be connected to the external thread of the connecting seat alone or to the external threads of both the connecting seat and the anti-disengagement sleeve at the same time.

[0011] As one technical solution of this application, the fixing component includes a first fixing frame fixed to the end of the hanger away from the ball head, and a second fixing member fixed to the bottom of the first fixing frame to support the bottom of the cable.

[0012] As one technical solution of this application, the inner ring of the first fixing frame is fixed with a first protective pad for protecting the top of the cable;

[0013] The inner ring of the second fastener is fixed with a second protective pad for protecting the bottom of the cable.

[0014] As one technical solution of this application, a plurality of dampers for supporting the bottom of the line stake are inclinedly arranged on the side of the line stake, and the top of the dampers is hinged to the outside of the line stake.

[0015] As one technical solution of this application, the pile is provided with a number of limiting seats corresponding to the number of dampers near the bottom side, and the limiting seats are cast inside the pile foundation.

[0016] The bottom of the damper is hinged to the top of the limit seat.

[0017] As one technical solution of this application, the stake includes a bottom pile, and the bottom end of the bottom pile is provided with a pre-embedded part that can be cast into the pile foundation.

[0018] As one technical solution of this application, the stake also includes an extension stake fixed to the top of the bottom stake, and the bottom end of the extension stake is provided with an extension portion that can extend downward and be inserted into the interior of the bottom stake.

[0019] The advantages of this utility model compared to the prior art are:

[0020] This application then installs the ball joint fixed at the top of the boom inside the spherical mounting groove, and then fixes the anti-detachment sleeve to the bottom of the connector, so that the anti-detachment sleeve installs the ball joint inside the spherical mounting groove. This effectively prevents the ball joint from falling out of the spherical mounting groove. The cable is then fixed to the bottom of the boom via a fixing assembly to prevent the cable from falling out. When the cable sways, the cable will drive the boom through the fixing assembly, and the boom will rotate along the spherical mounting groove via the ball joint fixed at the top. This effectively prevents the bracket assembly from bending or breaking, solving the problem of bracket assemblies being prone to bending or breaking. Attached Figure Description

[0031] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0032] See Figures 1-9 As shown, an anti-seismic transmission line pile includes a pile 1, a damper 2 installed at the bottom of the pile 1 for supporting it, a cantilever 4 installed at the top of the pile 1, and an adjustable support assembly 5 installed on the cantilever 4. The support assembly 5 includes a fixing rod 51 longitudinally fixed to one end of the cantilever 4, a connecting seat 511 installed at the bottom end of the fixing rod 51, and a spherical mounting groove 512 opened at the bottom end of the connecting seat 511.

[0033] The bracket assembly 5 also includes a hanger 54, the top of which is fixed with a ball head 541 that can be adapted to the ball mounting groove 512;

[0034] The outside of the boom 54 is provided with an anti-disengagement sleeve 53 that can be threadedly connected to the spherical mounting groove 512. The anti-disengagement sleeve 53 is used to prevent the ball head 541 from falling out of the spherical mounting groove 512.

[0035] The bottom end of the fixing rod 51 is provided with a fixing component 55 for fixing the cable.

[0036] Then, the ball head 541 fixed to the top of the boom 54 is installed inside the spherical mounting groove 512, and the anti-detachment sleeve 53 is fixed to the bottom of the connector 511, so that the anti-detachment sleeve 53 installs the ball head 541 inside the spherical mounting groove 512. This effectively prevents the ball head 541 from falling out of the spherical mounting groove 512. The cable is then fixed to the bottom of the boom 54 via the fixing assembly 55 to prevent the cable from falling out. When the cable sways, the cable will drive the boom 54 through the fixing assembly 55, and the boom 54 will rotate along the spherical mounting groove 512 via the ball head 541 fixed to the top. This effectively prevents the bracket assembly 5 from bending or breaking, solving the problem of the bracket assembly 5 being prone to bending or breaking.

[0037] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the connector 511 is provided with a nut 52 that can rotate along its central axis. The nut 52 can be connected to the external thread of the connector 511 alone or to the external threads of both the connector 511 and the anti-disengagement sleeve 53 at the same time.

[0038] To ensure a stable connection between the anti-loosening sleeve 53 and the connecting seat 511, the nut 52 is rotated, allowing it to move downwards along the central axis of the connecting seat 511 until its bottom engages with the external thread of the anti-loosening sleeve 53. At this point, the nut 52 simultaneously engages with the threads on both the outer surface of the connecting seat 511 and the outer surface of the anti-loosening sleeve 53, effectively increasing the stability between the anti-loosening sleeve 53 and the fixing rod 51, thereby increasing the load-bearing capacity of the anti-loosening sleeve 53.

[0039] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the fixing assembly 55 includes a first fixing bracket 551 fixed to the end of the hanger 54 away from the ball head 541, and a second fixing member 554 capable of supporting the bottom of the cable is fixed to the bottom of the first fixing bracket 551.

[0040] By fixing the second fixing member 554 to the bottom of the first fixing bracket 551, the first fixing bracket 551 can cooperate with the second fixing member 554 to fix the cable.

[0041] See Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the inner ring of the first mounting bracket 551 is fixed with a first protective pad 552 for protecting the top of the cable;

[0042] The inner ring of the second fastener 554 is fixed with a second protective pad 553 for bottom protection of the cable.

[0043] To prevent damage to the cable surface when the first fixing bracket 551 and the second fixing member 554 fix the cable, a first protective pad 552 is fixed to the inner ring of the first fixing bracket 551 and a second protective pad 553 is fixed to the inner ring of the second fixing member 554. This prevents the first fixing bracket 551 and the second fixing member 554 from directly contacting the cable, thus protecting the cable with the first protective pad 552 and the second protective pad 553.

[0044] See Figure 1 As shown, several dampers 2 are inclinedly arranged on the side of the stake 1 to support the bottom of the stake 1, and the top of the dampers 2 is hinged to the outside of the stake 1.

[0045] By hinged to the side of the line stake 1, the damper 2 can support the bottom of the line stake 1, effectively improving the stability of the line stake 1.

[0046] See Figure 1 As shown, the pile 1 is provided with a number of limiting seats 3 corresponding to the number of dampers 2 near the bottom side, and the limiting seats 3 are cast inside the pile foundation.

[0047] The bottom of the damper 2 is hinged to the top of the limit seat 3.

[0048] By casting the limiting seat 3 inside the pile foundation, and then hinged the bottom of the damper 2 to the top of the limiting seat 3, the limiting seat 3 can limit the bottom of the damper 2, effectively preventing the damper 2 from shifting when supporting the line pile 1.

[0049] See Figure 2 and Figure 3 As shown, the line stake 1 includes a bottom pile 10, and the bottom end of the bottom pile 10 is provided with a pre-embedded part 13 that can be cast into the pile foundation.

[0050] The stability of the line pile 1 is increased by setting a pre-embedded part 13 extending downward from the bottom of the bottom pile 10 and then casting the pre-embedded part 13 into the pile foundation.

[0051] See Figure 2 and Figure 3 As shown, the stake 1 also includes an extension stake 11 fixed to the top of the bottom stake 10. The bottom end of the extension stake 11 is provided with an extension portion 12 that can extend downward and be inserted into the bottom stake 10.

[0052] By setting extension piles 11 at the top of the base pile 10, multiple extension piles 11 can be provided. Then, an extension portion 12 that can extend downward and insert into the interior of the base pile 10 is provided at the bottom end of the extension pile 11. This not only ensures that the extension pile 11 and the base pile 10 can be accurately connected, but also improves the stability of the connection between the base pile 10 and the extension pile 11.

[0053] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
