Description

Technical Field

[0001] This utility model relates to the field of power transmission tower technology, and in particular to a structurally stable power transmission tower. Background Technology

[0002] Power transmission towers are tall structures used to support overhead power lines. They are mainly made of steel and are a key component of power transmission systems. They are mainly composed of the tower body, tower legs, and crossarms.

[0003] During the installation of power transmission towers, the bottom of the tower legs are inserted into pre-drilled holes in a concrete base, and then the legs are fixed by pouring concrete. The tower body is then spliced ​​together and fixed with bolts. When installing towers on hillsides, it is inconvenient to reinforce the tower body with ropes. Relying solely on the concrete base to support the tower body may lead to instability and tilting during long-term operation. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when installing power towers on hillsides, it is inconvenient to reinforce the tower body by pulling ropes, and the method of supporting the tower body only by concrete base may lead to low stability and tilting during long-term operation. The proposed invention is a structurally stable power tower.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a structurally stable power transmission tower, including tower legs, a tower body formed by splicing several steel structural frames on the outer surface of the tower legs, several crossarms formed by splicing several steel structural frames at the top of the tower body, and concrete bases at the bottom of the tower legs, the bottom of the tower legs being connected to the concrete base by concrete pouring, and a stabilizing device for reinforcing and stabilizing the bottom of the tower being provided on the outer surface of the concrete base.

[0006] The effect achieved by the above components is as follows: When installing power transmission towers, a concrete base is poured on the ground, and a hole is made at the top of the concrete base. The bottom end of the tower leg is inserted into the hole at the top of the concrete base, and then the bottom end of the tower leg is connected to the concrete base by pouring concrete. Subsequently, several steel structure frames are spliced ​​upward on the outer surface of the tower leg to form the tower body, and steel structure frames are spliced ​​at the top of the tower body to form a crossarm, which supports the insulators and conductors.

[0007] Preferably, the stabilizing device includes a ring that rotates at the top of a concrete base. A protruding rod is fixedly connected to one side of the top of the ring, and a grooved rod is fixedly connected to one side of the ring. A sliding groove is formed inside the groove, and a sliding rod is inserted into the inner wall of the sliding groove. A lead screw is inserted into one end of the sliding rod, and two threaded cylinders are threadedly connected to the outer surface of the lead screw. Several threaded holes are formed at the top of the concrete base and on the outer surface of the sliding rod, and several through holes are formed at one end of the protruding rod and on one side of the grooved rod.

[0008] The aforementioned components achieve the following effect: When installing the power transmission tower, before connecting the tower legs to the concrete base, the ring can be placed on the outer top of the base. The ring is then rotated to adjust the position of the grooved rod. Next, a bolt is inserted through the protruding rod into a threaded hole at the top of the concrete base. The bolt is then rotated to screw it into the threaded hole at the top of the concrete base, fixing the ring in place at the top of the concrete base. Then, one end of the sliding rod is inserted into the groove at one end of the grooved rod. The sliding rod is moved to adjust its length inside the grooved rod. Finally, a bolt is inserted through a through-hole on the outer surface of the grooved rod and into the threaded hole on the outer surface of the sliding rod. The ring is then rotated... Bolts are used to fix the slide rod inside the groove rod. Then, the lead rod is passed through one end of the slide rod. Two threaded sleeves are used to fit over the outer surface of the lead rod from top to bottom and from bottom to top, respectively. The lead rod is then pushed so that its bottom end is inserted into the ground. The two threaded sleeves on the outer surface of the lead rod are rotated to move the sleeves on the outer surface of the lead rod. One end of the threaded sleeve is pressed against the outer surface of the slide rod to fix the position of the lead rod. By inserting the bottom end of the lead rod into the ground, the position of the concrete base and the tower leg on the ground is further stabilized. This facilitates the support and reinforcement of the bottom of the power tower in locations where it is inconvenient to install guy ropes, thereby improving the stability of the power tower after installation.

[0009] Preferably, the inner shape of the groove is X-shaped, and the outer surface shape of the slide rod is adapted to the inner shape of the groove.

[0010] The effect achieved by the above components is that by setting the internal shape of the slide groove and the outer surface shape of the slide rod to be X-shaped, the structural strength at the contact point between the corner of the slide rod and the corner of the inner wall of the slide groove is higher when the slide rod is inserted into the slide groove.

[0011] Preferably, one end of the threaded cylinder is fixedly connected with a plurality of protrusions, which are distributed circumferentially on the outer surface of the threaded cylinder.

[0012] The effect achieved by the above components is that by pressing the protrusion on the outer surface of the threaded cylinder with your hand, it is easier to push the threaded cylinder to rotate and it is less likely to slip.

[0013] Preferably, limiting rods are fixedly connected to the upper and lower sides of the slide rod, and the outer surface of the limiting rods is L-shaped.

[0014] The effect achieved by the above components is that after one end of the slide rod is inserted into the groove rod, one side of each of the two limiting rods will fit against the upper and lower sides of the groove rod respectively, further limiting the angle between the slide rod and the groove rod, making it less likely for the angle of the slide rod inside the groove rod to deviate.

[0015] Preferably, a positioning rod is fixedly connected to one side of the bottom end of the slide rod, and a through hole is opened at the bottom end of the positioning rod.

[0016] The effect achieved by the above components is that when the lead screw is inserted into one end of the inner wall of the slide bar, the outer surface part will be inside the positioning rod. The positioning rod can further limit the angle between the lead screw and the slide bar, making it less likely for the lead screw to deviate to the left or right.

[0017] Preferably, the bottom end of the lead screw is provided with an auxiliary device, the auxiliary device including a threaded ring, the bottom end of the threaded ring is rotatably connected to a retaining ring, and the two sides of the retaining ring are fixedly connected to support rods.

[0018] The effect achieved by the above components is as follows: When installing the lead screw, a threaded ring can be inserted from bottom to top at the bottom of the lead screw. Pushing the threaded ring to rotate causes it to move upward on the outer surface of the lead screw, which in turn moves the retaining ring and the two support rods upward. After the bottom of the lead screw is inserted into the ground, the threaded ring can be pushed to rotate again, causing the support rods on both sides of the bottom of the retaining ring to abut against the ground, further supporting and reinforcing the lead screw and the tower as a whole.

[0019] Preferably, a positioning ring is rotatably connected to the outer surface of the threaded ring, and diagonal rods are fixedly connected to both sides of the positioning ring, with the end of the diagonal rod away from the positioning ring being fixedly connected to one side of the top of the support rod.

[0020] The effect achieved by the above components is that by setting diagonal braces, the connection between the support rod and the retaining ring can be further reinforced, thereby improving the overall structural strength of the auxiliary device.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this utility model, by setting up a stabilizing device, a ring and a grooved rod are fitted at the top of each concrete base, and the sliding rod and screw rod are fixed to one end of the grooved rod. By inserting the bottom end of the screw rod into the ground, the concrete base and tower leg are further stabilized on the ground. This facilitates the support and reinforcement of the bottom of the power tower in locations where it is inconvenient to install guy ropes, thereby improving the stability of the power tower after installation.

[0028] Example 1, such as Figure 1-2 As shown, a structurally stable power transmission tower includes tower legs 1. A tower body 4 is formed on the outer surface of the tower legs 1, and the tower body 4 is assembled from several steel structural frames. Several crossarms 5 are also assembled from several steel structural frames at the top of the tower body 4. A concrete base 6 is provided at the bottom of the tower legs 1. The bottom of the tower legs 1 and the concrete base 6 are connected by concrete pouring. A stabilizing device 2 is provided on the outer surface of the concrete base 6 to reinforce and stabilize the bottom of the tower. When installing the power transmission tower, the concrete base 6 is poured on the ground, and a hole is made at the top of the concrete base 6. The bottom of the tower legs 1 is inserted into the hole at the top of the concrete base 6, and then the bottom of the tower legs 1 is connected to the concrete base 6 by concrete pouring. Subsequently, several steel structural frames are sequentially assembled upwards on the outer surface of the tower legs 1 to form the tower body 4, and the steel structural frames are assembled at the top of the tower body 4 to form the crossarms 5, which support insulators and conductors.

[0029] Reference Figure 1-4As shown, in this embodiment: the stabilizing device 2 includes a ring 21, which rotates at the top of the concrete base 6. A protruding rod 23 is fixedly connected to one side of the top of the ring 21, and a grooved rod 22 is fixedly connected to one side of the ring 21. A sliding groove 24 is opened inside the grooved rod 22, and a sliding rod 25 is inserted into the inner wall of the sliding groove 24. A threaded rod 26 is inserted into one end of the sliding rod 25, and two threaded cylinders 27 are threadedly connected to the outer surface of the threaded rod 26. Several threaded holes are opened at the top of the concrete base 6 and on the outer surface of the sliding rod 25, and several through holes are opened at one end of the protruding rod 23 and one side of the grooved rod 22. When installing the power tower, before connecting the tower leg 1 to the concrete base 6, the ring 21 can be placed on the outer side of the top of the base, and the ring 21 can be pushed to rotate to adjust the position of the grooved rod 22. Then, a bolt is inserted through the protruding rod 23 into a threaded hole at the top of the concrete base 6. The bolt is rotated to screw the bolt into the threaded hole at the top of the concrete base 6, thus fixing the position of the ring 21 at the top of the concrete base 6. Next, insert one end of the slide rod 25 into the groove 24 at one end of the groove rod 22. Move the slide rod 25 to adjust its length inside the groove rod 22. Then, use a bolt to pass through the through hole on the outer surface of the groove rod 22 and insert it into the threaded hole on the outer surface of the slide rod 25. Rotate the bolt to fix the slide rod 25 inside the groove rod 22. Then, pass the lead screw 26 through one end of the slide rod 25. Use two threaded sleeves 27 to fit over the outer surface of the lead screw 26 from top to bottom and from bottom to top, respectively. Then push the lead screw 26 to make the thread... The bottom end of rod 26 is inserted into the ground. The two threaded cylinders 27 on the outer surface of the screw rod 26 are rotated to move the threaded cylinders 27 on the outer surface of the screw rod 26. One end of the threaded cylinder 27 is pressed against the outer surface of the slide rod 25 to fix the position of the screw rod 26. By inserting the bottom end of the screw rod 26 into the ground, the position of the concrete base 6 and the tower leg 1 on the ground is further stabilized. This facilitates the support and reinforcement of the bottom end of the power tower in locations where it is inconvenient to install guy ropes, thereby improving the stability of the power tower after installation.

[0030] Reference Figure 2-4 As shown in this embodiment: the internal shape of the slide groove 24 is X-shaped, and the outer surface shape of the slide rod 25 is adapted to the internal shape of the slide groove 24. By setting the internal shape of the slide groove 24 and the outer surface shape of the slide rod 25 to be X-shaped, the structural strength of the contact point between the corner of the slide rod 25 and the corner of the inner wall of the slide groove 24 is higher when the slide rod 25 is inserted into the slide groove 24. One end of the threaded cylinder 27 is fixedly connected with several protrusions 28. The protrusions 28 are distributed circumferentially on the outer surface of the threaded cylinder 27. By pressing the protrusions 28 on the outer surface of the threaded cylinder 27 with your hand, it is easier to push the threaded cylinder 27 to rotate and it is less likely to slip.

[0031] Reference Figure 2-4As shown in this embodiment: Limiting rods 29 are fixedly connected to the upper and lower sides of the slide rod 25 respectively. The outer surface of the limiting rods 29 is L-shaped. After one end of the slide rod 25 is inserted into the groove rod 22, one side of the two limiting rods 29 will respectively fit against the upper and lower sides of the groove rod 22, further limiting the angle between the slide rod 25 and the groove rod 22, so that the angle of the slide rod 25 inside the groove rod 22 is not easily deflected. A positioning rod 210 is fixedly connected to one side of the bottom end of the slide rod 25. The bottom end of the positioning rod 210 has a through hole. When the lead screw 26 is inserted into one end of the inner wall of the slide rod 25, the outer surface part will be inside the positioning rod 210. The positioning rod 210 can further limit the angle between the lead screw 26 and the slide rod 25, so that the lead screw 26 is not easily deflected to the left or right.

[0032] Reference Figure 1 , Figure 2 and Figure 4 As shown in this embodiment: an auxiliary device 3 is provided at the bottom end of the lead screw 26. The auxiliary device 3 includes a threaded ring 31, and a retaining ring 32 is rotatably connected to the bottom end of the threaded ring 31. Support rods 33 are fixedly connected to both sides of the retaining ring 32. When installing the lead screw 26, a threaded ring 31 can be inserted from bottom to top at the bottom end of the lead screw 26. Pushing the threaded ring 31 to rotate causes the threaded ring 31 to move upward on the outer surface of the lead screw 26, which in turn moves the retaining ring 32 and the two support rods 33 upward. After the bottom end of the lead screw 26 is inserted into the ground... The threaded ring 31 can be rotated to make the support rods 33 on both sides of the bottom end of the retaining ring 32 abut against the ground, further supporting and reinforcing the screw rod 26 and the entire tower. The outer surface of the threaded ring 31 is rotatably connected to the positioning ring 34. The two sides of the positioning ring 34 are respectively fixedly connected to the diagonal rods 35. The end of the diagonal rod 35 away from the positioning ring 34 is fixedly connected to the top side of the support rod 33. By setting the diagonal rods 35, the connection between the support rod 33 and the retaining ring 32 can be further reinforced, improving the overall structural strength of the auxiliary device 3.

[0033] Working principle: When installing the power transmission tower, a concrete base 6 is poured on the ground, and a hole is drilled at the top of the concrete base 6. A ring 21 is placed on the outer side of the top of the base, and the position of the groove rod 22 is adjusted by pushing the ring 21 to rotate. Then, a bolt is inserted through the protruding rod 23 into a threaded hole at the top of the concrete base 6. The bolt is rotated to screw the bolt into the threaded hole at the top of the concrete base 6, fixing the ring 21 at the top of the concrete base 6. Then, one end of the sliding rod 25 is inserted into the groove 24 at one end of the groove rod 22. The sliding rod 25 is moved to adjust the length of the sliding rod 25 extending into the groove rod 22. Then, a bolt is inserted through the through hole on the outer surface of the groove rod 22 on one side and into the threaded hole on the outer surface of the sliding rod 25. The bolt is rotated to fix the sliding rod 25 in the groove rod 22. Then, a lead rod 26 is passed through one end of the sliding rod 25. Two threaded cylinders 27 are respectively placed on the outer surface of the lead rod 26 from top to bottom and from bottom to top. A threaded ring 31 is then placed from bottom to top. A threaded ring 31 is pushed to rotate, causing the threaded ring 31 to move upward on the outer surface of the screw 26, which in turn moves the retaining ring 32 and two support rods 33 upward. After the bottom end of the screw 26 is inserted into the ground, the screw 26 is pushed again to insert the bottom end of the screw 26 into the ground. The two threaded cylinders 27 on the outer surface of the screw 26 are rotated to move the threaded cylinders 27 on the outer surface of the screw 26. One end of the threaded cylinder 27 is pressed against the outer surface of the slide rod 25 to fix the position of the screw 26. Then, the threaded ring 31 is pushed to rotate, causing the support rods 33 on both sides of the bottom end of the retaining ring 32 to press against the ground, further supporting and reinforcing the screw 26 and the entire tower. Then, the bottom end of the tower leg 1 is inserted into the opening at the top of the concrete base 6, and the bottom end of the tower leg 1 is connected to the concrete base 6 by concrete pouring. Then, several steel structure frames are used to splice the tower body 4 upward on the outer surface of the tower leg 1 in sequence, and the steel structure frames are used to splice the crossarm 5 at the top of the tower body 4. The crossarm 5 supports the insulators and conductors.
