Description

Technical Field

[0001] This invention relates to the field of transmission tower foundation technology, and in particular to an adjustable transmission tower foundation with omnidirectional adjustment function and an adjustment method thereof. Background Technology

[0002] Commonly used transmission towers are lattice-type transmission towers made of angle steel. Transmission towers typically have four legs, with a base plate at the bottom for connection to the tower foundation. The tower foundation is usually a reinforced concrete slab-column independent foundation, cast-in-place, and the foundation is generally connected to the base plate using anchor bolts pre-embedded within the foundation.

[0003] Due to geological disasters (such as landslides, subsidence, earthquakes, and debris flows) and foundation deformation (such as foundation compression deformation and surface deformation caused by coal mining), the foundations of transmission towers will experience displacement during use. The displacement of the transmission tower foundation can be decomposed into a superposition of simple displacements, including: vertical displacement, horizontal displacement, rotational displacement, and torsional displacement. The actual displacement of the transmission tower foundation is a combination of these four simple displacements.

[0004] Because the tower feet and foundations of transmission towers are typically bolted together, foundation displacement inevitably leads to tower foot displacement, which in turn causes overall tower displacement and tower deformation. Overall tower displacement alters the conductor alignment and increases tension; tower deformation can result in excessive stress on the tower's members, leading to instability and failure. In short, transmission tower foundation displacement seriously threatens the safety of transmission lines.

[0005] Since existing technology cannot completely prevent the occurrence of transmission tower foundation displacement, the main technical means to deal with transmission tower foundation displacement is to adjust the position of the tower feet to restore them to their original position or reach a suitable position. This is generally referred to as transmission tower leveling and straightening technology.

[0006] There are currently two methods for leveling and straightening transmission towers: One method involves adjusting the tower's feet along with its connected foundation, such as raising the foundation and then grouting the bottom of the foundation to bring both the foundation and the tower to the appropriate position. This method requires excavating the backfill soil on the foundation to completely expose it. Because it involves adjusting the foundation as well, this method is obviously more difficult and costly. The other method involves not moving the tower foundation but adjusting the connecting components between the tower's feet and the foundation. This method is obviously less difficult and less expensive, and is the more commonly used method for leveling and straightening transmission towers.

[0007] The main methods for adjusting the connection components between the tower feet and the foundation are the addition of steel shims and the addition of wedges.

[0008] The shim-adding adjustment method involves first loosening the bolts connecting the transmission tower foot plate to the foundation, then using jacks to lift the tower foot plate. One or more steel shims are then added under the foot plate. Finally, the jacks are removed, and the bolts are tightened again. This method only raises the vertical height of the tower foot plate and cannot be adjusted in other directions. Furthermore, a temporary structure needs to be added to the tower foot plate to secure the jacks.

[0009] The wedge adjustment method involves installing wedges between the tower's footplate and the foundation, using the movement of these wedges to adjust the distance between them. This method is primarily used to adjust the vertical displacement of the tower's feet, but its ability to adjust displacement in other directions is very weak, and the adjustment range for vertical displacement is very small (on the order of 10mm), making it difficult to meet the requirements of transmission towers for large adjustment distances (linear displacement on the order of 100mm). Summary of the Invention

Detailed Implementation

[0060] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 the present invention, and should not be construed as limiting the present invention.

[0061] The following is for reference. Figures 1-33 An adjustable base 1000 for a transmission tower with omnidirectional adjustment function is described according to an embodiment of the first aspect of the present invention.

[0062] like Figures 1-4 As shown, the adjustable foundation 1000 of the transmission tower with omnidirectional adjustment function according to the first aspect embodiment of the present invention includes: a concrete foundation 101, a concrete column 102 and an adjustable support 103.

[0063] Specifically, such as Figure 1 and Figure 2 As shown, a concrete column 102 is mounted on a concrete foundation 101; an adjustable support 103 is mounted on top of the concrete column 102. The adjustable support 103 includes a first plate 200, a second plate 300, and an adjusting mechanism 100. The first plate 200 and the second plate 300 are spaced apart vertically. One of the first plate 200 and the second plate 300 is used to install and fix the column base 2001 of the transmission tower 2000, and the other is connected to the concrete column 102. There are multiple adjusting mechanisms 100, which are spaced apart circumferentially from the first plate 200. Each adjusting mechanism 100 includes: The system comprises a first connector 11, a second connector 12, a third connector 13, a first support rod 21, and a second support rod 22. The first connector 11 is mounted on the first plate 200. The second connector 12 is slidably mounted on the second plate 300 along the circumference of the first plate 200. The third connector 13 is slidably mounted on the second plate 300 along the circumference of the first plate 200. The second connector 12 and the third connector 13 are spaced apart in the circumference of the first plate 200. The first support rod 21 connects the first connector 11 and the second connector 12, and the second support rod 22 connects the first connector 11 and the third connector 13.

[0064] In some examples, such as Figure 2 As shown, the concrete foundation 101 can be a cast-in-place foundation slab, a reinforced concrete structure. The plan shape of the concrete foundation 101 can be rectangular. The size and thickness of the concrete foundation 101 can be determined through design calculations based on the load of the transmission tower 2000 and the foundation conditions. Figure 3As shown, the concrete column 102 is a reinforced concrete structure and can be a precast component. The cross-sectional dimensions of the concrete column 102 are determined by design calculations based on the load of the transmission tower 2000 and the foundation conditions. The lower end of the concrete column 102 is connected to the concrete foundation 101, and the upper end of the concrete column 102 is connected to the adjusting support 103, which in turn connects to the transmission tower 2000.

[0065] In some examples, such as Figure 4 As shown, the first plate 200 and the second plate 300 of the adjusting support 103 are both flat plates, and both are made of steel plates to ensure the structural strength of the first plate 200 and the second plate 300. The first plate 200 and the second plate 300 are respectively arranged at the upper and lower ends of the adjusting support 103, and are respectively connected to the column base 2001 and the concrete column 102 of the transmission tower 2000. In some examples, the number of adjusting mechanisms 100 is two, three, four, five, six, seven, eight or more. Further, the number of adjusting mechanisms 100 is not less than four, and the multiple adjusting mechanisms 100 are evenly spaced in the circumferential direction of the second plate 300.

[0066] In some examples, such as Figures 4-7 As shown, the first connecting member 11 is disposed on the first plate 200. For example, the first connecting member 11 is fixed to the first plate 200 and cannot move relative to the first plate 200. Alternatively, the first connecting member 11 can be slidably disposed on the first plate 200 relative to the first plate 200. The second connecting member 12 and the third connecting member 13 can both be slidably disposed on the second plate 300. For example, the second connecting member 12 and the third connecting member 13 are provided with a first sliding part, and the second plate 300 is provided with a second sliding part. The first sliding part and the second sliding part can slide relative to each other in the horizontal plane. The first sliding part can be a slide rail, slider, slide groove, slide rod, or slide hole, etc., and the second sliding part can be a slide groove, slide rail, slider, slide rod, or slide hole adapted to the first sliding part. As long as the sliding cooperation between the second connecting member 12 and the third connecting member 13 and the second plate 300 can be achieved, this embodiment does not make specific limitations. It should be noted that the sliding direction of the second connector 12 on the second plate 300 and the sliding direction of the third connector 13 on the second plate 300 can be parallel or coincident with each other, or the sliding direction of the second connector 12 on the second plate 300 and the sliding direction of the third connector 13 on the second plate 300 can intersect.

[0067] In this embodiment, to ensure that the first support rod 21 and the second support rod 22 can slide along with the second connecting member 12 and the third connecting member 13 during the sliding process, the two ends of the first support rod 21 are rotatably connected to the first connecting member 11 and the second connecting member 12, respectively, and the two ends of the second support rod 22 are rotatably connected to the first connecting member 11 and the third connecting member 13, respectively. For example, the two ends of the first support rod 21 can be connected to the first connecting member 11 and the second connecting member 12 by ball joints, and the two ends of the second support rod 22 can also be connected to the second connecting member 12 and the third connecting member 13 by ball joints.

[0068] In this embodiment, between the first plate 200 and the second plate 300, the first connecting member 11 and the second connecting member 12 are connected by the first support rod 21, and the first connecting member 11 and the third connecting member 13 are connected by the second support rod 22. Thus, the first support rod 21, the second support rod 22 and the second plate 300 form a herringbone support structure. The first connecting member 11, the second connecting member 12 and the third connecting member 13 are the three vertices of the herringbone support structure. When multiple adjustment mechanisms 100 are connected between the first plate 200 and the second plate 300, multiple herringbone support adjustment mechanisms 100 are connected between the first plate 200 and the second plate 300.

[0069] Since at least two vertices (the second connecting member 12 and the third connecting member 13) of the A-frame adjustment mechanism 100 can slide, the height of the A-frame adjustment mechanism 100 can be changed by sliding the two vertices of the A-frame. When the heights of multiple A-frame adjustment mechanisms 100 are changed synchronously, the vertical distance between the first plate 200 and the second plate 300 can be adjusted, thereby realizing the vertical displacement adjustment function of the adjustable foundation 1000 of the transmission tower. When the height of some A-frame adjustment mechanisms 100 is changed, the heights of multiple adjustment mechanisms 100 are different, which can make the first plate 200 tilted relative to the second plate 300, thereby realizing the tilt displacement adjustment function of the adjustable foundation 1000 of the transmission tower. When the connecting piece 12 and the third connecting piece 13 slide counterclockwise or clockwise along the circumference of the first plate 200 and the second plate 300, the first plate 200 can rotate relative to the second plate 300 in the horizontal plane, thereby realizing the torsional displacement adjustment function of the adjustable foundation 1000 of the transmission tower, and thus realizing the displacement adjustment function of the adjustable foundation 1000 of the transmission tower in multiple directions; when multiple adjustment mechanisms 100 are arranged relative to each other in a certain direction, moving the second connecting piece 12 and the third connecting piece 13 of the relatively arranged adjustment mechanism 100 towards the same direction in the horizontal plane can move the first plate 200 relative to the second plate 300 towards that direction, thereby realizing the horizontal displacement adjustment function of the adjustable foundation of the transmission tower 2000.

[0070] In addition, in this embodiment, when adjusting the vertical displacement and tilt displacement, the height of the A-frame adjustment mechanism 100 is changed by adjusting the angle between the first support rod 21 and the second support rod 22. This can significantly increase the vertical displacement adjustment range, so that the vertical linear displacement adjustment range of the adjustable foundation 1000 of the transmission tower can reach more than 100mm and the tilt angle adjustment range can reach more than 3°.

[0071] According to an embodiment of the present invention, the adjustable foundation 1000 of the transmission tower with omnidirectional adjustment function is provided with an adjustment support 103 on the top of the concrete column 102, and a plurality of adjustment mechanisms 100 arranged circumferentially are provided between the first plate 200 and the second plate 300 of the adjustment support 103. The first support rod 21 and the second support rod 22 of each adjustment mechanism 100 are connected to the first plate 200 through the first connector 11, and are slidably connected to the second plate 300 through the second connector 12 and the third connector 13, respectively. Thus, by adjusting the position of the second connector 12 and the third connector 13, the height and position of the adjustment mechanism 100 can be changed, thereby enabling the adjustable foundation 1000 of the transmission tower to have displacement adjustment function in multiple directions, satisfying the requirements for the adjustment direction of the column foot 2001 of the transmission tower 2000 and the large displacement adjustment requirements after any displacement of the foundation of the transmission tower 2000.

[0072] In some embodiments of the present invention, such as Figures 4-6 As shown, the adjustment mechanism 100 further includes: a first slide rail 31, a second slide rail 32, and a third slide rail 33. The first slide rail 31 is fixed on the first plate 200. A first connecting member 11 is disposed on the first slide rail 31 and is rotatable relative to the first slide rail 31 about a first axis. The first axis is parallel to the sliding direction of the second connecting member 12 and the third connecting member 13. The second slide rail 32 is disposed on the second plate 300 and extends circumferentially along the second plate 300. The second connecting member 12 is slidably disposed on the second slide rail 32 and is rotatable relative to the second slide rail 32 about a second axis. The second axis is parallel to the first axis. The third slide rail 33 is disposed on the second plate 300 and is collinear with the second slide rail 32. The third connecting member 13 is slidably disposed on the third slide rail 33 and is rotatable relative to the third slide rail 33 about a third axis. The third axis coincides with the second axis.

[0073] In some examples, the second slide rail 32 and the third slide rail 33 are spaced apart circumferentially on the second plate 300, both extending in a straight line, and the extension directions of the second slide rail 32 and the third slide rail 33 are collinear. When the second connecting member 12 and the third connecting member 13 slide relative to the second plate 300, the sliding directions of the second connecting member 12 and the third connecting member 13 are consistent and collinear. This reduces the risk of the adjusting mechanism 100 jamming.

[0074] In this embodiment, the first connecting member 11 is rotatable on the first slide rail 31 around the first axis, the second connecting member 12 is rotatable on the second slide rail 32 around the second axis, and the third connecting member 13 is rotatable on the third slide rail 33 around the third axis. The first axis, the second axis, and the third axis are parallel to each other, and the second axis and the third axis are collinear. When the multiple adjusting mechanisms 100 are arranged opposite each other in the first and second directions perpendicular to each other in the horizontal plane, in order to realize the horizontal adjustment of the first plate 200 relative to the second plate 300, the second connecting member 12 and the third connecting member 13 of the adjusting mechanism 100 arranged opposite each other in the first direction can be moved as a whole along the second direction. At the same time, the first connecting member 11 of the adjusting mechanism 100 arranged opposite each other in the second direction can be rotated relative to the first slide rail 31 around the first axis, and the second connecting member 12 and the third connecting member 13 can be rotated around the second and third axes, thereby realizing the horizontal displacement adjustment function of the adjustable foundation 1000 of the transmission tower.

[0075] In some embodiments of the present invention, such as Figures 5-6 As shown, the adjusting mechanism 100 also includes a first pin 41, the axis of which is perpendicular to the first axis. A first shaft hole 1121 is formed on the first connecting plate 112 of the first connecting member 11. One end of the first support rod 21 (e.g.) Figure 6 and Figure 7 The upper end of the first support rod 21 shown is provided with a second shaft hole 211, and one end of the second support rod 22 (e.g.) Figure 6 and Figure 7 The upper end of the second support rod 22 shown in the diagram is provided with a third shaft hole 221. A first pin 41 passes through the first shaft hole 1121, the second shaft hole 211, and the third shaft hole 221, so that one end of the first support rod 21 and one end of the second support rod 22 are rotatably connected to the first connecting plate 112. This simplifies the connection structure between the first connecting plate 112 and the first support rod 21 and the second support rod 22, making installation easier.

[0076] In some embodiments of the present invention, such as Figure 5 As shown, the adjusting mechanism 100 also includes a second pin 42, the axis of which is perpendicular to the second axis. A fourth shaft hole 1221 is formed on the second connecting plate 122 of the second connecting member 12. The other end of the first support rod 21 (e.g.) Figure 5 The lower end of the first support rod 21 shown is provided with a fifth shaft hole 212. The second pin 42 passes through the fourth shaft hole 1221 and the fifth shaft hole 212 so that the other end of the first support rod 21 is rotatably connected to the second connecting plate 122. This simplifies the connection structure between the second connecting piece 12 and the first support rod 21 and facilitates installation.

[0077] In some embodiments of the present invention, such as Figure 5As shown, the adjusting mechanism 100 also includes a third pin 43, the axis of which is perpendicular to the third axis. A sixth shaft hole 1321 is formed on the third connecting plate 132 of the third connecting member 13. The other end of the second support rod 22 (e.g.) Figure 5 The lower end of the second support rod 22 shown is provided with a seventh shaft hole 222. The third pin 43 passes through the sixth shaft hole 1321 and the seventh shaft hole 222 so that the other end of the second support rod 22 is rotatably connected to the third connecting plate 132. This simplifies the connection structure between the third connecting piece 13 and the second support rod 22 and facilitates installation.

[0078] In some embodiments of the present invention, such as Figures 5-7 As shown, the first slide rail 31 forms a first slide groove 311 that opens toward the second plate 300. The first slide groove 311 includes a first arc portion 3111 and a first clearance portion 3112 connected to the side of the first arc portion 3111 facing the second plate 300. The cross-section of the first arc portion 3111 is an arc. In the direction from the first plate 200 toward the second plate 300, the width of the first clearance portion 3112 gradually increases. The first connecting member 11 includes a first slider 111 and a first connecting plate 112. The shape of the first slider 111 is adapted to the first arc portion 3111 and it is rotatably fitted inside the first arc portion 3111. One end of the first connecting plate 112 is connected to the first slider 111, and the other end extends through the first clearance portion 3112 to the outside of the first slide groove 311 to connect one end of the first support rod 21 and one end of the second support rod 22.

[0079] like Figures 5-7 As shown, the first slide rail 31 has a downward-opening first groove 311. The first arcuate portion 3111 of the first groove 311 is an arcuate groove with a superior arc cross-section. The first clearance portion 3112 is connected to the lower side of the first arcuate portion 3111, and the cross-section of the first clearance portion 3112 is an isosceles trapezoid with a smaller upper section and a larger lower section. The first slider 111 of the first connecting member 11 is a columnar body with an arcuate cylindrical surface. The first slider 111 is rotatably fitted into the first arcuate portion 3111, so that the first connecting member 11 and the first slide rail 31 are rotatably connected around the first axis. The first connecting plate 112 is flat. In the direction from top to bottom, the two side surfaces of the first connecting plate 112 extend towards each other in the width direction. The upper end of the first connecting plate 112 is connected to the first slider 111, and the lower end extends downward through the first clearance portion 3112 to the lower side of the first slide rail 31.

[0080] When the first slider 111 rotates within the first arc portion 3111, the first clearance portion 3112 provides clearance space for the first connecting plate 112, allowing the first connecting plate 112 to swing along with the first slider 111 within the first clearance portion 3112, thus preventing interference between the first connecting plate 112 and the first slide rail 31. Furthermore, the opposite sidewalls of the first clearance portion 3112 can limit the swing angle of the first connecting plate 112, thereby limiting the relative rotation angle between the first connecting member 11 and the first slide rail 31, restricting the maximum horizontal displacement adjustment distance between the first plate 200 and the second plate 300, and simultaneously ensuring the support stability of the adjustment mechanism 100 between the first plate 200 and the second plate 300.

[0081] In some examples, to facilitate the assembly between the first connector 11 and the first slide rail 31, such as Figure 6 and Figure 7 As shown, the first slide rail 31 includes a first track portion 312 and a first end plate 313. The first track portion 312 defines a first groove 311 that is open at least one end. The first end plate 313 is fixed to at least one end of the first track portion 312 by a first fastener to cover the open end of the first groove 311. That is, the first track portion 312 may be open at only one end in the length direction, or the first track portion 312 may be open at both ends in the length direction. During the assembly of the first connector 11 and the first slide rail 31, the first slider 111 of the first connector 11 can be inserted into the first groove 311 from the open end of the first track portion 312, and then the open end of the first groove 311 can be covered by the first end plate 313 to prevent the first connector 11 from slipping out of the first groove 311. In this embodiment, by making the first slide rail 31 include a first track portion 312 and a first end plate 313 that are separately arranged, it is not only convenient to assemble the first connector 11, but also to simplify the structure and facilitate the separate processing of the first track portion 312 and the first end plate 313, thereby reducing the processing difficulty.

[0082] Furthermore, such as Figure 6 and Figure 7 As shown, the first end plate 313 may be provided with a plurality of first fastening holes, and the first track portion 312 is provided with a plurality of second fastening holes. The plurality of first fastening holes are spaced apart in the circumferential direction of the first end plate 313 and correspond one-to-one with the plurality of second fastening holes. The first end plate 313 is fixed to the end of the first track portion 312 by a plurality of first fasteners passing through the corresponding first fastening holes and second fastening holes.

[0083] In some embodiments of the present invention, such as Figures 4-6As shown, the second slide rail 32 forms a second slide groove 321 that opens toward the first plate 200. The second slide groove 321 includes a second arc portion 3211 and a second clearance portion 3212 connected to the side of the second arc portion 3211 facing the first plate 200. The cross-section of the second arc portion 3211 is an arc. In the direction from the second plate 300 toward the first plate 200, the width of the second clearance portion 3212 gradually increases. The second connecting member 12 includes a second slider 121 and a second connecting plate 122. The shape of the second slider 121 is adapted to the second arc portion 3211 and is rotatably fitted inside the second arc portion 3211. It can slide along the length direction of the second arc portion 3211. One end of the second connecting plate 122 is connected to the second slider 121, and the other end extends through the second clearance portion 3212 to the outside of the second slide groove 321 to connect to the other end of the first support rod 21.

[0084] like Figures 5-7 As shown, the second slide rail 32 has an upward-opening second slide groove 321. The second arcuate portion 3211 of the second slide groove 321 is an arcuate groove with a superior arc cross-section. The second clearance portion 3212 is connected to the upper side of the second arcuate portion 3211, and the cross-section of the second clearance portion 3212 is an isosceles trapezoid with a larger upper section and a smaller lower section. The second slider 121 of the second connector 12 is a columnar body with an arcuate cylindrical surface. The second slider 121 is rotatably fitted into the second arcuate portion 3211, so that the second connector 12 and the second slide rail 32 are rotatably connected around the second axis. The second connecting plate 122 is flat. The width of the second connecting plate 122 gradually decreases from bottom to top. Specifically, the surface of the second connecting plate 122 facing away from the third connector 13 in the width direction extends obliquely toward the third connector 13. The lower end of the second connecting plate 122 is connected to the second slider 121, and the upper end extends through the second clearance portion 3212 to the upper side of the second slide rail 32.

[0085] When the second slider 121 rotates within the second arc portion 3211, the second clearance portion 3212 provides clearance space for the second connecting plate 122, allowing the second connecting plate 122 to swing along with the second slider 121 within the clearance portion 3212, thus preventing interference between the second connecting plate 122 and the second slide rail 32. Furthermore, the opposite sidewalls of the second clearance portion 3212 can limit the swing angle of the second connecting plate 122, thereby limiting the relative rotation angle between the second connecting member 12 and the second slide rail 32, restricting the maximum horizontal displacement adjustment distance between the first plate 200 and the second plate 300, and simultaneously ensuring the support stability of the adjustment mechanism 100 between the first plate 200 and the second plate 300.

[0086] In some examples, to facilitate the assembly between the second connector 12 and the second slide rail 32, such as Figure 6 and Figure 7As shown, the second slide rail 32 includes a second track portion 322 and a second end plate 323. The second track portion 322 defines a second slide groove 321 that is open at least one end. The second end plate 323 is fixed to at least one end of the second track portion 322 by a second fastener to cover the open end of the second slide groove 321. That is, the second track portion 322 may be open at only one end in the length direction, or it may be open at both ends in the length direction. During the assembly of the second connector 12 and the second slide rail 32, the second slider 121 of the second connector 12 can be inserted into the second slide groove 321 from the open end of the second track portion 322, and then the open end of the second slide groove 321 can be covered by the second end plate 323 to prevent the second connector 12 from slipping out of the second slide groove 321. In this embodiment, by making the second slide rail 32 include a second track portion 322 and a second end plate 323 that are separately arranged, it is not only convenient to assemble the second connector 12, but also to simplify the structure, facilitate the separate processing of the second track portion 322 and the second end plate 323, and reduce the processing difficulty.

[0087] Furthermore, such as Figure 6 and Figure 7 As shown, the second end plate 323 may be provided with a plurality of third fastening holes, and the second track portion 322 is provided with a plurality of fourth fastening holes. The plurality of third fastening holes are spaced apart in the circumferential direction of the second end plate 323 and correspond one-to-one with the plurality of fourth fastening holes. The second end plate 323 is fixed to the end of the second track portion 322 by a plurality of second fasteners passing through the corresponding third fastening holes and fourth fastening holes.

[0088] In some embodiments of the present invention, such as Figures 4-6 As shown, the third slide rail 33 forms a third slide groove 331 that opens toward the first plate 200. The third slide groove 331 includes a third arc portion 3311 and a third clearance portion 3312 connected to the side of the third arc portion 3311 facing the first plate 200. The cross-section of the third arc portion 3311 is an arc. In the direction from the second plate 300 toward the first plate 200, the width of the third clearance portion 3312 gradually increases. The third connector 13 includes a third slider 131 and a third connecting plate 132. The shape of the third slider 131 is adapted to the third arc portion 3311 and is rotatably fitted inside the third arc portion 3311. It can slide along the length direction of the third arc portion 3311. One end of the third connecting plate 132 is connected to the third slider 131, and the other end extends through the third clearance portion 3312 to the outside of the third slide groove 331 to connect to the other end of the second support rod 22.

[0089] like Figures 5-7As shown, the third slide rail 33 has an upward-opening third slide groove 331. The third arc portion 3311 of the third slide groove 331 is an arc-shaped groove with a superior arc cross-section. The third clearance portion 3312 is connected to the upper side of the third arc portion 3311. The cross-section of the third clearance portion 3312 is an isosceles trapezoid with a larger upper section and a smaller lower section. The third slider 131 of the third connector 13 is a columnar body with an arc cylindrical surface. The third slider 131 is rotatably fitted within the third arc portion 3311, realizing that the third connector 13 and the third slide rail 33 are rotatably connected around the third axis. The third connecting plate 132 is flat. The width of the third connecting plate 132 gradually decreases from bottom to top. Specifically, the surface of the third connecting plate 132 facing away from the second connecting member 12 in the width direction extends obliquely toward the second connecting member 12. The lower end of the third connecting plate 132 is connected to the third slider 131, and the upper end extends through the third clearance part 3312 to the upper side of the third slide rail 33.

[0090] When the third slider 131 rotates within the third arc portion 3311, the third clearance portion 3312 provides clearance space for the third connecting plate 132, allowing the third connecting plate 132 to swing along with the third slider 131 within the third clearance portion 3312, thus preventing interference between the third connecting plate 132 and the third slide rail 33. Furthermore, the opposing sidewalls of the third clearance portion 3312 can limit the swing angle of the third connecting plate 132, thereby limiting the relative rotation angle between the third connecting member 13 and the third slide rail 33, restricting the maximum horizontal displacement adjustment distance between the first plate 200 and the second plate 300, and simultaneously ensuring the support stability of the adjustment mechanism 100 between the first plate 200 and the second plate 300.

[0091] In some examples, to facilitate the assembly between the third connector 13 and the third slide rail 33, such as Figure 6 and Figure 7As shown, the third slide rail 33 includes a third track portion 332 and a third end plate 333. The third track portion 332 defines a third slide groove 331 that is open at least one end. The third end plate 333 is fixed to at least one end of the third track portion 332 by a third fastener to cover the open end of the third slide groove 331. That is, the third track portion 332 may be open only at one end in the length direction, or it may be open at both ends in the length direction. During the assembly of the third connector 13 and the third slide rail 33, the third slider 131 of the third connector 13 can be inserted into the third slide groove 331 from the open end of the third track portion 332 first, and then the open end of the third slide groove 331 can be covered by the third end plate 333 to prevent the third connector 13 from slipping out of the third slide groove 331. In this embodiment, by making the third slide rail 33 include the third track part 332 and the third end plate 333 separately arranged, it is not only convenient to assemble the third connector 13, but also to simplify the structure, facilitate the separate processing of the third track part 332 and the third end plate 333, and reduce the processing difficulty.

[0092] Furthermore, such as Figure 6 and Figure 7 As shown, the third end plate 333 may be provided with a plurality of fifth fastening holes, and the third track portion 332 is provided with a plurality of sixth fastening holes. The plurality of fifth fastening holes are spaced apart in the circumferential direction of the third end plate 333 and correspond one-to-one with the plurality of sixth fastening holes. The third end plate 333 is fixed to the end of the third track portion 332 by a plurality of third fasteners passing through the corresponding fifth fastening holes and sixth fastening holes.

[0093] In some examples, such as Figure 5 and Figure 6 As shown, the second track portion 322 of the second slide rail 32 and the third track portion 332 of the third slide rail 33 are formed as a single piece, and the second groove 321 of the second track portion 322 and the groove of the third track portion 332 are the same groove. This not only reduces the number of parts, but also eliminates the need to consider the alignment difficulties of the collinearity of the second and third tracks during assembly, thus improving assembly efficiency.

[0094] In some embodiments of the present invention, such as Figure 5 and Figure 6As shown, the adjustment mechanism 100 further includes: a first adjusting member 51 and a second adjusting member 52. The first adjusting member 51 is connected to the second connecting member 12 and is used to drive the second connecting member 12 to slide along the second slide rail 32; the second adjusting member 52 is connected to the third connecting member 13 and is used to drive the third connecting member 13 to slide along the third slide rail 33. By operating the first adjusting member 51 and the second adjusting member 52, the positions of the second connecting member 12 and the third connecting member 13 can be adjusted, thereby improving the adjustment efficiency. In some examples, either the first adjusting member 51 or the second adjusting member 52 can be an adjusting rod, an adjusting handle, an adjusting motor, or an adjusting cylinder.

[0095] In some embodiments of the present invention, such as Figure 6 and Figure 7 As shown, the second connector 12 is provided with a sliding direction along the second connector 12 (e.g., Figure 6 The first adjusting hole 1211 (shown in the left-right direction) passes through the second connecting member 12. The first adjusting hole 1211 is a threaded hole. The first adjusting member 51 includes: a first screw section 511, a first bearing portion 512, and a first nut portion 513. The first screw section 511 passes through the first adjusting hole 1211. The first bearing portion 512 is disposed between the first screw section 511 and the first nut portion 513. The second slide rail 32 is provided with a first bearing hole. The first bearing portion 512 is disposed in the first bearing hole so that the first adjusting member 51 is rotatably connected to the second slide rail 32 around the first bearing portion 512. At least a portion of the first nut portion 513 extends beyond the end face of the second slide rail 32 away from the third slide rail 33.

[0096] In some examples, such as Figure 6 As shown, the second slide rail 32 includes a second track portion 322 and a second end plate 323. The second track portion 322 defines a second slide groove 321 with open ends. The second end plate 323 is disposed at one end of the second track portion 322 away from the third track. The second end plate 323 is provided with a first through hole 3231. A first nut portion 513 extends through the first through hole 3231 to the outside of the second slide rail 32.

[0097] When the position of the second connector 12 needs to be adjusted, the first nut 513 can be rotated to make the first adjusting member 51 rotate around the first bearing 512 relative to the second slide rail 32. The first nut 513 drives the first screw section 511 to rotate synchronously. Since the first screw section 511 is threadedly engaged with the first adjusting hole 1211 (threaded hole) on the second connector 12, under the action of thread transmission, the second connector 12 generates a linear displacement relative to the first adjusting member 51 along its sliding direction, thereby driving the second connector 12 to slide relative to the second slide rail 32, realizing the adjustment of the relative position between the second connector 12 and the second slide rail 32.

[0098] In the above technical solution, by having the first bearing portion 512 engage with the first bearing hole, the first adjusting member 51 can be rotatably mounted on the second slide rail 32, reducing the resistance of the first adjusting member 51 during rotation, ensuring smooth rotation, and preventing jamming during adjustment. The threaded engagement between the first screw section 511 and the threaded hole of the second connecting member 12 allows for more continuous and precise adjustment of the position of the second connecting member 12, making the adjustment operation more convenient. Furthermore, by having the first nut portion 513 extend beyond the end face of the second slide rail 32, adjustment can be performed directly from the outside, improving the convenience of adjustment.

[0099] In some embodiments of the present invention, such as Figure 6 and Figure 7 As shown, the third connector 13 is provided with a sliding direction along the third connector 13 (e.g., Figure 6 The second adjusting hole 1311 (shown in the left-right direction) passes through the third connecting member 13. The second adjusting hole 1311 is a threaded hole. The second adjusting member 52 includes a second screw section 521, a second bearing portion 522, and a second nut portion 523. The second screw section 521 passes through the second adjusting hole 1311. The second bearing portion 522 is disposed between the second screw section 521 and the second nut portion 523. The third slide rail 33 is provided with a second bearing hole. The second bearing portion 522 is disposed in the second bearing hole so that the second adjusting member 52 is rotatably connected to the third slide rail 33 around the second bearing portion 522. At least a portion of the second nut portion 523 extends beyond the end face of the third slide rail 33 away from the second slide rail 32.

[0100] In some examples, such as Figure 6 As shown, the third slide rail 33 includes a third track portion 332 and a third end plate 333. The third track portion 332 defines a third slide groove 331 that is open at both ends. The third end plate 333 is disposed at one end of the third track portion 332 away from the second track. The third end plate 333 is provided with a second through hole 3331. The second nut portion 523 extends through the second through hole 3331 to the outside of the third slide rail 33.

[0101] When the position of the third connector 13 needs to be adjusted, the second nut 523 can be rotated to make the second adjusting member 52 rotate relative to the third slide rail 33 around the second bearing 522. The second nut 523 drives the second screw section 521 to rotate synchronously. Since the second screw section 521 is threadedly engaged with the second adjusting hole 1311 (threaded hole) on the third connector 13, under the action of thread transmission, the third connector 13 generates a linear displacement relative to the second adjusting member 52 along its sliding direction, thereby driving the third connector 13 to slide relative to the third slide rail 33, realizing the adjustment of the relative position between the third connector 13 and the third slide rail 33.

[0102] In the above technical solution, by fitting the second bearing portion 522 into the second bearing hole, the second adjusting member 52 can be rotatably mounted on the third slide rail 33, reducing the resistance of the second adjusting member 52 during rotation, ensuring smooth rotation, and preventing jamming during adjustment. The threaded engagement of the second screw section 521 with the threaded hole of the third connecting member 13 allows for more continuous and precise adjustment of the third connecting member's position, making the adjustment operation more convenient. Furthermore, by extending the second nut portion 523 beyond the end face of the third slide rail 33, adjustment can be performed directly from the outside, improving adjustment convenience.

[0103] In some embodiments of the present invention, such as Figure 22 and Figure 23 As shown, the first connecting member 11 is slidably disposed on the first slide rail 31 along the extension direction of the first axis. The adjustment mechanism 100 further includes a third adjusting member 53 and a fourth adjusting member 54. The third adjusting member 53 is connected to the first connecting member 11 and is used to drive the first connecting member 11 to slide along the first slide rail 31. The fourth adjusting member 54 is connected to the second connecting member 12 and the third connecting member 13 and is used to drive the second connecting member 12 and the third connecting member 13 to move towards or away from each other along the second slide rail 32 and the third slide rail 33, respectively. The sliding directions of the first connecting member 11, the second connecting member 12, and the third connecting member 13 are the same. In this embodiment, by operating the third adjusting member 53, the position of the first connecting member 11 can be adjusted; by operating the fourth adjusting member 54, the positions of the second connecting member 12 and the third connecting member 13 can be adjusted simultaneously, improving adjustment efficiency. In some examples, either the third adjusting member 53 or the fourth adjusting member 54 can be an adjusting rod, an adjusting handle, an adjusting motor, or an adjusting cylinder.

[0104] In the above embodiments, since the first connecting member 11 is slidable, and the second connecting member 12 and the third connecting member 13 can move towards or away from each other, when it is necessary to adjust the height of the A-frame adjustment mechanism 100 to realize the vertical displacement adjustment function or tilt displacement adjustment function of the adjustable foundation 1000 of the transmission tower, the first connecting member 11 can be fixed, and the second connecting member 12 and the third connecting member 13 can be moved by the fourth adjusting member 54 to change the angle between the second support rod 22 and the first support rod 21, thereby realizing the adjustment of the first connecting member 11 and the second connecting member 12 and the third connecting member 13. The distance between the three connecting members 13 in the vertical direction; when it is necessary to realize the torsional displacement adjustment function of the adjustable foundation 1000 of the transmission tower, the second connecting member 12 and the third connecting member 13 can be fixed, and the first connecting member 11 is driven to slide relative to the first plate 200 by the third adjusting member 53. Since the second connecting member 12 and the third connecting member 13 do not move, when the third adjusting member 53 drives the first connecting member 11, the first connecting member 11 is not moved, and the first plate 200 slides relative to the first connecting member 11, realizing the rotation of the first plate 200 relative to the second plate 300. Thus, in this embodiment, the third adjusting member 53 can realize the horizontal displacement adjustment between the first connecting member 11 and the first plate 200 responsible for adjusting the mechanism 100, and the fourth adjusting member 54 can realize the height adjustment of the mechanism 100 in the vertical direction.

[0105] In some embodiments of the present invention, such as Figure 22 and Figure 23 As shown, the first connector 11 is provided with a third adjusting hole 1111 that extends through the first connector 11 along the sliding direction of the first connector 11. The third adjusting hole 1111 is a threaded hole. The third adjusting member 53 includes a third screw section 531, a third bearing portion 532, and a third nut portion 533. The third screw section 531 passes through the third adjusting hole 1111. The third bearing portion 532 is connected between the third screw section 531 and the third nut portion 533. The first slide rail 31 is provided with a third bearing hole. The third bearing portion 532 is disposed in the third bearing hole so that the third adjusting member 53 is rotatably connected to the first slide rail 31 around the third bearing portion 532. At least a portion of the third nut portion 533 extends to the end face beyond one end of the second slide rail 32.

[0106] In some examples, such as Figure 23 As shown, the first slide rail 31 includes a first track portion 312 and a first end plate 313. The first track portion 312 defines a first slide groove 311 with open ends. There are two second end plates 323, which are respectively disposed at both ends of the first track portion 312. One of the first end plates 313 is provided with a third through hole, and a third nut portion 533 extends through the third through hole to the outside of the first slide rail 31.

[0107] When the position of the first connecting member 11 needs to be adjusted, the third nut 533 can be rotated to make the third adjusting member 53 rotate relative to the first slide rail 31 around the third bearing 532. The third nut 533 drives the third screw section 531 to rotate synchronously. Since the third screw section 531 is threadedly engaged with the third adjusting hole 1111 (threaded hole) on the first connecting member 11, under the action of thread transmission, the first connecting member 11 generates a linear displacement relative to the third adjusting member 53 along its sliding direction, thereby driving the first connecting member 11 to slide relative to the first slide rail 31, realizing the adjustment of the relative position between the first connecting member 11 and the first slide rail 31.

[0108] In the above technical solution, by using the third bearing portion 532 to engage with the third bearing hole, the third adjusting member 53 can be rotatably mounted on the first slide rail 31, reducing the resistance of the third adjusting member 53 during rotation, ensuring smooth rotation, and preventing jamming during adjustment. The threaded engagement of the third screw section 531 with the threaded hole of the first connecting member 11 allows for more continuous and precise adjustment of the position of the first connecting member 11, making the adjustment operation more convenient. Furthermore, by extending the third nut portion 533 beyond the end face of the first slide rail 31, adjustment can be performed directly from the outside, improving the convenience of adjustment.

[0109] In some embodiments of the present invention, such as Figure 22 and Figure 23 As shown, the second connecting member 12 is provided with a first adjusting hole 1211, and the third connecting member 13 is provided with a second adjusting hole 1311. Both the first adjusting hole 1211 and the second adjusting hole 1311 are threaded holes. The fourth adjusting member 54 includes: a fourth screw section 541, a fifth screw section 542, a fourth bearing part 543, and a fourth nut part 544. The fourth nut part 544 is located between the second slide rail 32 and the third slide rail 33. The two fourth bearing parts 543 are respectively located on both sides of the fourth nut part 544. The fourth adjusting member 54 is connected by two... The fourth bearing section 543 is rotatably connected to the second slide rail 32 and the third slide rail 33 respectively. The fourth screw section 541 is connected to one of the fourth bearing sections 543 on the side facing the second slide rail 32, and passes through the first adjusting hole 1211 and is threadedly connected to the second connecting member 12. The fifth screw section 542 is connected to the other fourth bearing section 543 on the side facing the third slide rail 33, and passes through the second adjusting hole 1311 and is threadedly connected to the third connecting member 13. The threads of the fourth screw section 541 and the fifth screw section 542 have opposite directions of rotation.

[0110] When it is necessary to adjust the positions of the second connecting member 12 and the third connecting member 13, the fourth nut 544 is rotated, and the fourth adjusting member 54 rotates relative to the second slide rail 32 and the third slide rail 33 around the fourth bearing 543. The fourth screw section 541 and the fifth screw section 542 rotate together with the fourth adjusting member 54. Since the fourth screw section 541 is threadedly engaged with the first adjusting hole 1211 and the fifth screw section 542 is threadedly engaged with the second adjusting hole 1311, and the threads of the fourth screw section 541 and the fifth screw section 542 rotate in opposite directions, under the action of thread transmission, the second connecting member 12 and the third connecting member 13 move closer or further away synchronously in opposite directions, thereby realizing the synchronous adjustment of the relative distance between the second connecting member 12 and the third connecting member 13.

[0111] In the above technical solution, the fourth adjusting member 54 is rotatably connected to the second slide rail 32 and the third slide rail 33 through two fourth bearing parts 543, which can reduce the resistance of the fourth adjusting member 54 during rotation, make the rotation smooth, and avoid jamming during adjustment. The fourth screw section 541 is threadedly engaged with the first adjusting hole 1211 of the second connecting member 12, and the fifth screw section 542 is threadedly engaged with the second adjusting hole 1311 of the third connecting member 13, which can make the position adjustment of the second connecting member 12 and the third connecting member 13 more continuous and precise, and the adjustment operation more convenient. Furthermore, by arranging the fourth nut portion 544 between the first slide rail 31 and the second slide rail 32, the fourth screw segment 541 and the fifth screw segment 542 can be symmetrically arranged on both sides of the fourth nut portion 544. During the adjustment process, the fourth screw segment 541 and the fifth screw segment 542 are subjected to balanced forces, ensuring the consistency of the movement of the second connecting member 12 and the third connecting member 13. It can also realize the simultaneous adjustment of the positions of the second connecting member 12 and the third connecting member 13, improving the adjustment efficiency, making the adjustment operation simpler, and the structure more compact.

[0112] In some embodiments of the present invention, such as Figure 4 and Figure 5As shown, the adjusting support 103 further includes: a plurality of support components 400, which are supported between the first plate 200 and the second plate 300. The plurality of support components 400 are arranged at intervals along the circumference of the first plate 200. Each support component 400 includes: a bottom wedge 401, a middle wedge 402, and a top wedge 403. The bottom wedge 401 is disposed on the second plate 300, and its upper end surface is an inclined first slope 4011. The lower end surface of the middle wedge 402 is a second slope 4021 parallel to the first slope 4011. The first inclined surface 4011 and the second inclined surface 4021 are in contact, and the tangent of the angle between the first inclined surface 4011 and the horizontal plane is less than the coefficient of sliding friction between the first inclined surface 4011 and the second inclined surface 4021. The upper end surface of the middle wedge 402 is a first spherical surface 4022 that is raised upward or recessed downward. The lower end surface of the top wedge 403 is a second spherical surface 4031 that is adapted to the first spherical surface 4022. The first spherical surface 4022 and the second spherical surface 4031 are in contact, and the upper end surface of the top wedge 403 abuts against the first plate 200 in the vertical direction.

[0113] In some examples, the number of support components 400 can be two, three, four, five, six or more, with multiple support components 400 evenly spaced circumferentially around the first plate 200 to improve the uniformity of force distribution between the multiple first plates 200 and the second plate 300. This embodiment, by adding support components 400 between the first plate 200 and the second plate 300, can significantly improve the vertical bearing capacity of the adjustable support 103, making it suitable for situations where the column base 2001 of the transmission tower 2000 experiences high pressure.

[0114] In some examples, the bottom wedge 401, the middle wedge 402, and the top wedge 403 are all made of steel and can be formed by cutting a cubic steel substrate. The bottom surface of the bottom wedge 401 is flat and is used to contact the second plate 300. The top surface of the bottom wedge 401 is a first inclined surface 4011, which is used to contact the second inclined surface 4021 at the bottom of the middle wedge 402. By changing the relative position of the first inclined surface 4011 and the second inclined surface 4021, the height of the support assembly 400 in the vertical direction can be changed to accommodate the support requirements of different plate spacings between the first plate 200 and the second plate 300. Wherein, the tangent of the angle between the first inclined plane 4011 and the horizontal plane is less than the coefficient of sliding friction between the first inclined plane 4011 and the second inclined plane 4021, so that the inclination angle of the first inclined plane 4011 and the second inclined plane 4021 needs to meet the frictional self-locking requirement between the first inclined plane 4011 and the second inclined plane 4021 under vertical pressure.

[0115] Furthermore, the top surface of the top wedge 403 is a flat surface for contacting the first plate 200. The bottom surface of the top wedge 403 and the top surface of the middle wedge 402 are respectively a first spherical surface 4022 and a second spherical surface 4031. One of the first spherical surface 4022 and the second spherical surface 4031 is a convex spherical surface and the other is a concave spherical surface. The shapes of the first spherical surface 4022 and the second spherical surface 4031 match to achieve surface contact. When the tilt displacement between the first plate 200 and the second plate 300 is adjusted by adjusting the support 103, the top wedge 403 can rotate relative to the middle wedge 402 around the center of the first spherical surface 4022 and the second spherical surface 4031 to adapt to the tilt angle of the first plate 200. At the same time, it ensures the surface contact force transmission between the top wedge 403 and the middle wedge 402, ensuring the vertical load-bearing capacity of the support assembly 400.

[0116] In some embodiments of the present invention, such as Figure 4 , Figure 5 and Figures 9-13 As shown, the second plate 300 is a rectangular plate connected to the concrete column 102. There are four adjusting mechanisms 100, each located on one of the four sides of the second plate 300. The sliding directions of the second connector 12 and the third connector 13 of each adjusting mechanism 100 are parallel to the corresponding edge of the second plate 300. This allows the four adjusting mechanisms to be evenly distributed circumferentially on the second plate 300, improving the uniformity of force distribution between the first plate 200 and the second plate 300, and also facilitating the arrangement of multiple adjusting mechanisms 100. Furthermore, there are four support components 400, arranged inside the four adjusting mechanisms 100, with each support component 400 corresponding to one of the four adjusting mechanisms 100.

[0117] In some embodiments of the present invention, such as Figure 4 , Figure 5 , Figures 14-17As shown, the first plate 200 is a circular or rectangular plate. The first plate 200 is connected to the column base 2001 of the transmission tower 2000 by connecting bolts 2002. The first plate 200 is provided with a lifting clearance hole 201 that runs vertically through the first plate 200. The lifting clearance hole 201 is used to avoid the jack 3000. For example, the lifting clearance hole 201 is located at the center of the first plate 200. Multiple support components 400 are arranged inside multiple adjustment mechanisms 100. The multiple support components 400 enclose an arrangement space. The lifting clearance hole 201 is located directly above the arrangement space. When adjustment is required, the jack 3000 can be placed in the arrangement space. The lifting component of the jack 3000 can pass through the lifting clearance hole 201 to lift the column base 2001 of the transmission tower 2000. This allows for easy lifting of the transmission tower 2000, reducing the pressure on the regulating mechanism 100, and facilitating displacement adjustment of the adjustable foundation 1000 of the transmission tower.

[0118] In some embodiments of the present invention, such as Figure 2 and Figure 5 As shown, the concrete column 102 is a precast component. The second plate 300 and the concrete column 102 are connected as a whole by precast casting. The concrete column 102 has multiple bottom plate anchor bars 1021, which are vertically arranged and whose upper ends are fixedly connected to the second plate 300. In this embodiment, the concrete column 102 is made as a precast component, which allows the concrete column 102 to be produced in a standardized and mass-produced manner in a factory. This is beneficial to improving production efficiency and molding quality, shortening the on-site construction cycle, and forming an integrated structure with the second plate 300 of the adjustable support 103 and the concrete column 102 by precast casting. This can improve the reliability and integrity of the connection between the second plate 300 and the concrete column 102, improve the structural stability of the adjustable foundation 1000 of the transmission tower, and avoid assembly errors and weak connection problems caused by secondary on-site connection.

[0119] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the concrete foundation 101 is cast-in-place concrete, and the lower end of the concrete column 102 is integrally connected to the concrete foundation 101 by casting. In this embodiment, by connecting the concrete column 102 and the cast-in-place concrete foundation 101 by casting, the structural integrity and connection reliability of the concrete column 102 and the concrete foundation 101 can be improved, enabling the effective transfer of vertical and horizontal loads between the concrete column 102 and the concrete foundation 101, thereby improving the overall structural stability and seismic performance. Furthermore, as... Figure 2 and Figure 3As shown, the concrete column 102 has column anchor bars 1022, which extend downwards from the concrete column 102 and into the concrete foundation 101. Thus, through the interlocking action between the column anchor bars 1022 and the concrete, the connection strength, pull-out resistance, and shear resistance between the concrete column 102 and the concrete foundation 101 are further enhanced, preventing problems such as loosening or detachment at the connection point.

[0120] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the concrete column 102 includes a column head section 1023, a column body section 1024, and a transition section 1025. The cross-sectional dimension of the column head section 1023 is larger than that of the column body section 1024. The transition section 1025 connects the column head section 1023 and the column body section 1024. The cross-sectional dimension of the transition section 1025 gradually decreases from the column head section 1023 toward the column body section 1024. The upper end of the column head section 1023 is connected to the adjusting support 103, and the lower end of the column body section 1024 is connected to the concrete foundation 101. In this embodiment, the concrete column 102 includes a column head section 1023, a transition section 1025, and a column body section 1024 connected sequentially from top to bottom. By adopting a segmented structure with different cross-sectional dimensions, the column head section 1023, with its larger cross-sectional dimension, can provide sufficient arrangement space and support area for the top adjustable support 103, ensuring the connection stability between the adjustable support 103 and the concrete column 102. The transition section 1025, with its gradually decreasing cross-sectional dimension, can achieve a smooth stress transition, effectively reducing stress concentration and improving the overall load-bearing capacity and structural durability of the concrete column 102. The column body section 1024, while meeting the load-bearing requirements, uses a smaller cross-sectional dimension, which can reduce its self-weight, save materials, and facilitate on-site construction and installation.

[0121] Furthermore, such as Figure 3 As shown, in order to improve the structural strength and load-bearing capacity of the column head section 1023, the concrete column 102 also includes column head reinforcement 1026. The column head reinforcement 1026 is arranged at least in the column head section 1023 and the transition section 1025 at a position where the cross-sectional dimension exceeds that of the column body section 1024, and the lower end of the column head reinforcement 1026 can extend to the column body section 1024.

[0122] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the adjustable foundation 1000 of the transmission tower also includes a protective housing, within which the adjusting support 103 is housed. The protective housing protects the adjusting support 103, preventing it from being corroded or damaged, and improving its durability.

[0123] According to a second aspect of the present invention, an adjustment method is applied to an adjustable foundation 1000 of a transmission tower having omnidirectional adjustment function according to the first aspect of the present invention. The adjustment method includes:

[0124] S1, confirm that the current displacement of the adjustable foundation 1000 of the transmission tower exceeds the preset threshold.

[0125] For example, monitoring points can be preset on the adjustable foundation 1000 and concrete column 102 of the transmission tower. A displacement monitoring device can then be used to collect real-time data on the horizontal, vertical, and tilt displacements of the adjustable foundation 1000. The collected current displacement data is then compared with a preset displacement threshold. When the current displacement data exceeds the preset threshold, it can be confirmed that the current displacement of the adjustable foundation 1000 exceeds the preset threshold.

[0126] S2, based on the current displacement, confirm the displacement adjustment type and displacement adjustment value of the adjustable foundation 1000 of the transmission tower. The displacement adjustment types include vertical displacement adjustment, horizontal displacement adjustment, tilting displacement adjustment and torsional displacement adjustment.

[0127] In other words, after acquiring the current displacement data of the adjustable foundation 1000 of the transmission tower, the current displacement data is compared and analyzed with the preset safe displacement threshold. Based on the direction, magnitude, and form of the displacement deviation, the corresponding displacement adjustment type and value are determined. Specifically, the displacement adjustment types in this scheme are divided into vertical displacement adjustment, horizontal displacement adjustment, tilting displacement adjustment, and torsional displacement adjustment. For each type of displacement deviation, the corresponding displacement adjustment value is calculated and determined, thus providing clear control parameters for the subsequent precise adjustment of the adjustable foundation 1000 of the transmission tower. This ensures that the support surface of the adjustable foundation 1000 for the transmission tower 2000 can be quickly and accurately reset to the design position, ensuring that the structure of the transmission tower 2000 is in a safe and stable working state.

[0128] S3, jack 3000 is placed between the first plate 200 and the second plate 300, and the transmission tower 2000 is lifted by jack 3000 to reduce the load on the adjusting support 103.

[0129] Before lifting the tower 2000 using jack 3000, loosen the connecting bolts 2002 between the column base 2001 and the first plate 200. Lifting the tower 2000 using jack 3000 can transfer part or all of the load on the tower 2000 and the adjusting support 103 to jack 3000, thereby reducing the load on the adjusting support 103 itself. This makes the subsequent adjustment of the adjusting support 103 safer and simpler, avoids jamming or damage to the adjusting mechanism 100 due to excessive load during the adjustment process, and ensures smooth adjustment operation.

[0130] S4, when the displacement adjustment type is vertical displacement adjustment, the second connecting member 12 and the third connecting member 13 of the multiple adjustment mechanisms 100 are controlled to slide relative to the second plate 300, adjusting the included angle between the first support rod 21 and the second support rod 22 so that the first plate 200 moves vertically relative to the second plate 300; when the displacement adjustment type is horizontal displacement adjustment, the second connecting member 12 and the third connecting member 13 are controlled to slide relative to the second plate 300, while keeping the included angle between the first support rod 21 and the second support rod 22 unchanged, or the first connecting member 11 is controlled to slide relative to the first plate 200 so that the first plate 200 moves horizontally relative to the second plate 300; when the displacement adjustment type is tilt displacement adjustment, the second connecting member 12 and the third connecting member 13 of the adjustment mechanism 100 are controlled to slide relative to the second plate 300 so that the first plate 200 moves horizontally relative to the second plate 300. Some of the multiple adjustment mechanisms 100 have different heights in the vertical direction. When the displacement adjustment type is torsional displacement adjustment, the second connecting member 12 and the third connecting member 13 of the multiple adjustment mechanisms 100 are controlled to slide relative to the second plate 300, and the included angle between the first support rod 21 and the second support rod 22 is kept unchanged. The second connecting member 12 and the third connecting member 13 of the multiple adjustment mechanisms 100 are controlled to slide synchronously in the clockwise or counterclockwise direction in the circumferential direction of the second plate 300. Alternatively, the first connecting member 11 of the multiple adjustment mechanisms 100 is controlled to slide relative to the first plate 200, and the first connecting member 11 of the multiple adjustment mechanisms 100 is controlled to slide synchronously in the clockwise or counterclockwise direction in the circumferential direction of the first plate 200, so that the first plate 200 rotates relative to the second plate 300 in the horizontal plane.

[0131] S5, adjust the height of the multiple support components 400 in the vertical direction so that the multiple support components 400 are supported between the first plate 200 and the second plate 300; S6, control the unloading of the jack 3000; S7, remove the jack 3000 from the adjusting support 103. Further, after step S5, the adjustment method may also include tightening the connecting bolts 2002.

[0132] According to the adjustment method of the present invention, vertical displacement adjustment, horizontal displacement adjustment, tilting displacement adjustment and torsional displacement adjustment of the adjustable foundation 1000 of the transmission tower can be realized. After any displacement of the adjustable foundation 1000 of the transmission tower, the first plate 200 of the column foot 2001 supporting the transmission tower 2000 can be reset to the design position by adjustment, so as to ensure the safety and stability of the transmission tower 2000.

[0133] The following will refer to Figures 1-33 The adjustable base 1000 for a transmission tower according to two specific embodiments of the present invention is described.

[0134] Example 1, refer to Figures 1-3As shown, the adjustable foundation 1000 for a transmission tower with omnidirectional adjustment function in this embodiment includes a concrete foundation 101, concrete columns 102, and adjustable supports 103. The concrete columns 102 are precast foundation columns. The concrete columns 102 and the adjustable supports 103 are precast in a factory and assembled as a whole. The concrete foundation 101 is a cast-in-place concrete slab structure with a rectangular plan shape. The concrete foundation 101 is cast on-site. Before the concrete foundation 101 is poured, the precast concrete columns 102 are installed within the formwork of the concrete foundation 101. The precast concrete columns 102 are then fixedly connected to the cast-in-place concrete foundation 101 by pouring concrete into the concrete foundation 101, forming a unified foundation.

[0135] like Figure 3 As shown, the concrete column 102 is a reinforced concrete structure. The concrete column 102 consists of a column head section 1023, a transition section 1025, and a column body section 1024 connected sequentially from top to bottom. The column head section 1023 is used to connect with the adjusting support 103, and the column body section 1024 is used to connect with the concrete foundation 101. The cross-sectional dimensions of the column head section 1023 are not less than the minimum cross-sectional dimensions required for the adjusting support 103 to be installed and fixed within the concrete column 102. The cross-sectional dimensions of the column body section 1024 are determined through design calculations based on the transmission tower 2000 load and foundation conditions. The column head section 1023 and the column body section 1024 are transitioned by a transition section 1025 with gradually changing cross-sectional dimensions to reduce stress concentration. The concrete column 102 is equipped with vertically arranged column anchor bars 1022, the lower end of which extends downward and outward beyond the bottom surface of the concrete column 102 to meet the anchoring requirements of the column anchor bars 1022 within the concrete foundation 101. The column head section 1023 of the concrete column 102 is equipped with bottom plate anchor bars 1021, which are used to strengthen the anchoring zone of the second plate 300 at the bottom of the adjusting support 103.

[0136] like Figure 4 and Figure 5 As shown, the adjustable support 103 includes a first plate 200, a second plate 300, four adjusting mechanisms 100, and four support assemblies 400. The first plate 200 is positioned above the second plate 300, and the four adjusting mechanisms 100 and four support assemblies 400 are positioned between the first plate 200 and the second plate 300. All four adjusting mechanisms 100 are formed into an A-frame structure. Each support assembly 400 includes multiple wedges arranged sequentially from top to bottom. During normal use, the support assembly 400 is placed between the first plate 200 and the second plate 300 to bear most of the vertical load of the adjustable support 103, thereby reducing the pressure on the A-frame-shaped adjusting mechanisms 100 during normal use.

[0137] like Figure 14As shown, the first plate 200 is made of steel plate, and its planar shape is circular or rectangular. Multiple first bolt holes 202 are formed on the first plate 200. These first bolt holes 202 are used to insert connecting bolts 2002 that connect to the foot plates of the transmission tower 2000's column base 2001. The diameter of the first bolt holes 202 is slightly larger than the diameter of the connecting bolts 2002. A lifting clearance hole 201 is formed in the center of the first plate 200. This lifting clearance hole 201 allows the jack 3000 to pass through the first plate 200 and directly contact the foot plates of the transmission tower 2000's column base 2001 for lifting and unloading.

[0138] like Figure 9 As shown, the second plate 300 is made of steel plate and has a rectangular planar shape. Multiple anchor holes 301 are provided at the four corners and the center of the second plate 300. These anchor holes 301 are used to insert bottom plate anchor bars 1021, connecting the bottom plate anchor bars 1021 to the second plate 300 to increase the connection strength and reliability between the second plate 300 and the bottom plate anchor bars 1021. The second plate 300 is anchored to the top of the precast concrete column 102 via the bottom plate anchor bars 1021.

[0139] The adjustment mechanism 100 includes a first slide rail 31, a second slide rail 32, a third slide rail 33, a first connecting member 11, a second connecting member 12, a third connecting member 13, a first support rod 21, a second support rod 22, a first adjusting member 51, and a second adjusting member 52. The first slide rail 31 is located on the first plate 200, the first connecting member 11 is located on the first slide rail 31, the second slide rail 32 and the third slide rail 33 are located on the second plate 300, the second connecting member 12 and the third connecting member 13 are located on the second slide rail 32 and the third slide rail 33, respectively, the two ends of the first support rod 21 are rotatably connected to the first connecting member 11 and the second connecting member 12, and the two ends of the second support rod 22 are rotatably connected to the first connecting member 11 and the third connecting member 13. All components of the adjustment mechanism 100 are made of steel.

[0140] The second track portion 322 of the second slide rail 32 and the third track portion 332 of the third slide rail 33 are integrally formed track components and are fixed to the top surface of the second plate 300, generally by welding. The length direction of the second slide rail 32 and the third slide rail 33 is parallel to the side length of the second plate 300. The second connecting member 12 and the third connecting member 13 are respectively installed in the second slide rail 32 and the third slide rail 33, and are symmetrical from left to right. The length of the second connecting member 12 is less than the length of the second slide rail 32, and it slides within the second slide rail 32 along the length direction of the second slide rail 32. At the same time, the second connecting member 12 can rotate slightly within the second slide rail 32 along the axis of the second slide rail 32. The first adjusting member 51 and the second adjusting member 52 are both adjusting screws. The first adjusting member 51 and the second adjusting member 52 are respectively fixed to the opposite ends of the second slide rail 32 and the third slide rail 33. The screw ends of the first adjusting member 51 and the second adjusting member 52 are respectively inserted into the threaded holes of the second connecting member 12 and the third connecting member 13. The two ends of the track component are fixed with screws to the second end plate 323 and the third end plate 333, respectively, which are used to fix the horizontal position of the first adjusting member 51 and the second adjusting member 52. The nuts of the first adjusting member 51 and the second adjusting member 52 extend beyond the second end plate 323 and the third end plate 333, respectively, so that the first adjusting member 51 and the second adjusting member 52 can be adjusted by rotating them with a wrench.

[0141] The first track portion 312 of the first slide rail 31 is welded to the bottom surface of the first plate 200. The length direction of the first track portion 312 is parallel to the second slide rail 32. The two ends of the first track portion 312 are fixed with screws to the first end plate 313, which fixes the horizontal position of the first connecting member 11. The first connecting member 11 is installed inside the first slide rail 31, and the length of the first connecting member 11 is equal to that of the first track portion 312. The first connecting member 11 cannot slide along the length direction of the first slide rail 31, but it can rotate slightly along the axis of the first arc portion 3111 of the first groove 311 inside the first slide rail 31.

[0142] The upper end of the first support rod 21 is connected to the first connector 11 by a first pin 41, and the lower end is connected to the second connector 12 by a second pin 42. The upper end of the second support rod 22 is connected to the first connector 11 by a first pin 41, and the lower end is connected to the third connector 13 by a third pin 43.

[0143] The first track section 312 is rectangular in shape. A first groove 311, opening downwards and extending through the length of the rectangular prism, is formed along its length. The cross-sectional shape of the first groove 311 is a symmetrical figure of a circle and a trapezoid, with the circle on top and the trapezoid on the bottom. A portion of the lower part of the circle (less than a semicircle) overlaps with the trapezoid. The trapezoid is narrower at the top and wider at the bottom, and the width of the upper end of the trapezoid is greater than the thickness of the plane of the first connecting member 11. Screw holes are provided at both ends of the first track 31 for fixing screws to secure the first end plate 313.

[0144] The track component, consisting of the second track section 322 and the third track section 332, is generally similar in structure to the first slide rail 31. The difference between the track component and the first track section 312 is that the opening of the groove on the track component faces upwards, the length of the track component is greater than that of the first slide rail 31, and the diameter of the circular cross-section at both ends of the groove is increased to accommodate and match the second bearing section 522 of the second adjusting member 52 and the third bearing section 532 of the third adjusting member 53. Multiple screw holes are present at both ends of the track component for fixing screws used to secure the second end plate 323 and the third end plate 333.

[0145] The first end plate 313 is a rectangular flat plate, and its shape is the same as the cross-sectional shape of the first track portion 312. The four corners of the first end plate 313 are provided with first fastening holes for inserting screws to fix the first end plate 313 to the end of the first track portion 312, and the screw nuts are recessed into the plane of the first end plate 313.

[0146] The second end plate 323 and the third end plate 333 have the same structure and are similar to the first end plate 313. The difference between the second end plate 323 and the third end plate 333 and the first end plate 313 is that the second end plate 323 and the third end plate 333 are respectively provided with a first through hole 3231 and a second through hole 3331 at their centers. The first through hole 3231 and the second through hole 3331 are respectively used for the first nut portion 513 of the first adjusting member 51 and the second nut portion 523 of the second adjusting member 52 to pass through and be exposed.

[0147] The first connecting member 11 is shaped like a cylindrical first slider 111 plus a flat first connecting plate 112. The cylindrical first slider 111 is on top, and the first connecting plate 112 is connected to the lower side of the first slider 111. The cylindrical first slider 111 is used to fix the first connecting member 11 within the first arcuate portion 3111 of the first slide groove 311, and to give the first slider 111 a certain rotational capacity along the cylindrical axis within the first slide groove 311. The first connecting plate 112 protrudes downwards from the first slide rail 31, and is used to connect the first support rod 21 and the second support rod 22. The central axis of the cylindrical first slider 111 is parallel to the plane of the first connecting plate 112, and the central axis of the first slider 111 is located on the center plane of the first connecting plate 112. The diameter of the first slider 111 is greater than the thickness of the first connecting plate 112. The diameter of the first slider 111 is equal to the diameter of the first arc portion 3111 of the first groove 311. The first shaft hole 1121 is opened at the center of the first connecting plate 112 for the first pin 41 connecting the first support rod 21 and the second support rod 22 to pass through.

[0148] The second connector 12 is similar to the first connector 11. The difference between the second connector 12 and the first connector 11 is that the cylindrical second slider 121 of the second connector 12 is at the bottom, and the flat second connecting plate 122 is at the top. A first adjusting hole 1211 is formed at the center of the cylinder of the second slider 121, which runs through the axis, allowing the first screw section 511 of the first adjusting member 51 to pass through. The third connector 13 has the same structure as the second connector 12.

[0149] The first adjusting member 51 consists of three sections: a first screw section 511, a first bearing section 512, and a first nut section 513. The thread of the first screw section 511 matches the thread of the first adjusting hole 1211 on the second connecting member 12. The first bearing section 512 is a disc-shaped bearing used to fix the first adjusting member 51. The diameter of the first bearing section 512 is larger than the diameter of the second slider 121 of the second connecting member 12. The diameter of the second bearing section 512 matches the diameter of the first bearing hole at one end of the second track section 322. The first nut section 513 is used to rotate the first adjusting member 51 using a wrench. The structure of the second adjusting member 52 is the same as that of the first adjusting member 51 and is arranged symmetrically with the first adjusting member 51.

[0150] The following reference Figures 9-19 The assembly process of the adjusting support 103 in this embodiment is described.

[0151] 1) Install the four second slide rails 32 on the top surface of the second plate 300, such as... Figure 10 As shown; 2) Install the four second connectors 12 and the four third connectors 13 into the four track components respectively, as shown. Figure 11As shown; 3) Install the four first adjusting members 51 and the four second adjusting members 52 into the corresponding second connecting members 12 and third connecting members 13, respectively, as shown. Figure 12 As shown; 4) Install the four second end plates 323 and the four third end plates 333 at both ends of the four track components, as shown. Figure 13 As shown; 5) Install the four first track sections 312 on the bottom surface of the first plate 200, as shown. Figure 15 As shown; 6) Install the four first connectors 11 into the four first track sections 312, as shown. Figure 16 As shown; 7) Install the eight first end plates 313 at both ends of the four first track sections 312 respectively, as shown. Figure 17 As shown; 8) Install the lower ends of the four first support rods 21 onto the four second connectors 12 respectively using the second pins 42, and install the lower ends of the four second support rods 22 onto the four third connectors 13 respectively using the third pins 43; 9) Install the top ends of the four first support rods 21 and the top ends of the four second support rods 22 onto the four first connectors 11 of the first plate 200 respectively using the first pins 41; 10) Complete the assembly of the adjusting support 103, as shown. Figure 18 As shown.

[0152] After the adjusting support 103 is assembled, the bottom plate anchor bar 1021 is fixed to the second plate 300 of the adjusting support 103, which can be achieved by welding or threaded connection. The second plate 300 and the anchor bar are fixed in the formwork of the precast concrete column 102, and the concrete of the precast concrete column 102 is poured. After the concrete of the concrete column 102 has solidified, the precast concrete column 102 and the second plate 300 of the adjusting support 103 can be connected as a whole.

[0153] After the adjustable foundation 1000 of the transmission tower is completed, when installing the transmission tower 2000, the foot plates of the column base 2001 of the transmission tower 2000 are fixed to the first plate 200 of the adjusting support 103 with connecting bolts 2002, thus completing the installation of the adjustable foundation 1000 and the transmission tower 2000. It should be noted that when the pressure on the column base 2001 of the transmission tower 2000 is not high, the load of the transmission tower 2000 can be borne by the A-frame shaped adjusting mechanism 100 between the first plate 200 and the second plate 300 of the adjusting support 103. When the pressure on the column base 2001 of the transmission tower 2000 is high, a support assembly 400 is installed between the first plate 200 and the second plate 300, and the support assembly 400 bears most of the vertical pressure.

[0154] The top wedge 403, middle wedge 402, and bottom wedge 401 of the support assembly 400 are all made of steel and are cubic in shape, machined by cutting. The top surface of the top wedge 403 is flat and contacts the bottom surface of the first plate 200. The bottom surface of the top wedge 403 is a concave first spherical surface 4022. The bottom surface of the bottom wedge 401 is flat and contacts the top surface of the second plate 300. The top surface of the bottom wedge 401 is cut into an inclined first slope 4011. The top surface of the middle wedge 402 is a convex second spherical surface 4031. The shape of the second spherical surface 4031 matches the shape of the first spherical surface 4022. The bottom surface of the middle wedge 402 is cut into an inclined second slope 4021, which is used to contact the first slope 4011. The support assembly 400 can transmit vertical pressure between the first plate 200 and the second plate 300 of the adjusting support 103. After the top wedge 403, the middle wedge 402, and the bottom wedge 401 are installed, they can achieve frictional self-locking under vertical pressure, and the support assembly 400 has a large vertical load-bearing capacity after self-locking. At the same time, the bottom wedge 401 and the middle wedge 402 work together to facilitate the clamping operation of the support assembly 400 between the second plate 300 and the first plate 200.

[0155] The following describes the construction method of the adjustable foundation 1000 for the transmission tower in this embodiment.

[0156] 1) Produce and assemble all components of the adjustable support 103 in the factory; 2) Produce precast concrete columns 102 in the precast component factory. During the production of concrete columns 102, place the adjustable support 103 into the formwork and pour concrete to form an integral unit with the concrete columns 102; 3) Erect the formwork for the cast-in-place concrete foundation 101 and tie the reinforcing steel bars at the construction site; 4) Install the precast concrete columns 102 inside the formwork of the cast-in-place concrete foundation 101; 5) Pour the concrete for the concrete foundation 101, and remove the formwork after the concrete has cured; 6) The construction of the adjustable foundation 1000 of the transmission tower is completed. During construction, pay attention to the temporary protection of the adjustable support 103 to prevent damage.

[0157] The following describes the adjustment method of the adjustable foundation 1000 of the transmission tower in this embodiment.

[0158] 1) After discovering that the displacement of the adjustable foundation 1000 of the transmission tower exceeds the limit, determine the displacement adjustment value of the adjustable foundation 1000 of the transmission tower.

[0159] 2) Use jack 3000 for unloading. Place jack 3000 between the second plate 300 and the first plate 200 of the adjusting support 103, and use jack 3000 to lift and partially unload the load, reducing the pressure on the adjusting mechanism 100. Before lifting with jack 3000, loosen connecting bolt 2002.

[0160] 3) Vertical displacement adjustment. By turning the first adjusting member 51 and the second adjusting member 52 with a wrench, the horizontal sliding of the first connecting member 11 and the second connecting member 12 is controlled, so that the included angle of the first support rod 21 and the second support rod 22 changes, and the height of the A-frame support-shaped adjusting mechanism 100 is adjusted, thereby achieving the purpose of adjusting the height of the adjusting support 103.

[0161] Horizontal displacement adjustment. Use a wrench to rotate the first adjusting member 51 and the second adjusting member 52 to control the horizontal sliding of the first connecting member 11 and the second connecting member 12. During adjustment, keep the included angle between the first support rod 21 and the second support rod 22 unchanged, that is, keep the height of the A-frame brace-shaped adjusting mechanism 100 unchanged. Adjusting the horizontal position of the A-frame brace adjusting mechanism 100 can achieve the purpose of adjusting the horizontal displacement of the first plate 200 of the adjusting support 103.

[0162] Tilt displacement adjustment. By turning the first adjusting member 51 and the second adjusting member 52 with a wrench, the horizontal sliding of the first connecting member 11 and the second connecting member 12 is controlled, so that the included angle of the first support rod 21 and the second support rod 22 changes, thereby adjusting the height of the A-frame brace adjustment mechanism 100. By controlling the height adjustment values ​​of the four A-frame brace adjustment mechanisms 100 to be inconsistent, the purpose of adjusting the relative tilt of the first plate 200 and the second plate 300 of the adjustment support 103 can be achieved.

[0163] Torsional displacement adjustment. Using a wrench, rotate the first adjusting member 51 and the second adjusting member 52 to control the horizontal sliding of the first connecting member 11 and the second connecting member 12. During adjustment, keep the included angle between the first support rod 21 and the second support rod 22 constant. Adjust the horizontal position of the four A-frame support adjustment mechanisms 100 synchronously clockwise or counterclockwise to achieve the purpose of adjusting the horizontal rotation of the first plate 200 of the adjusting support 103. Because the relative torsional displacement of the first plate 200 and the second plate 300 will cause the first slide rail 31 and the second slide rail 32 to no longer be parallel, the torsional adjustment can only be performed in small increments, and the adjustment range cannot be too large. However, the probability and magnitude of torsion in the transmission tower foundation are very small. The adjusting support 103 of this embodiment can meet the torsional adjustment requirements of the transmission tower 2000.

[0164] 4) Tighten the support assembly 400. After adjusting the displacement of the support 103 into place, tighten the bottom wedge 401 and the middle wedge 402 so that the vertical load is mainly borne by the support assembly 400, and tighten the connecting bolts 2002.

[0165] 5) Remove jack 3000. Unload jack 3000. At this time, the vertical load is mainly borne by support component 400, and jack 3000 can be removed.

[0166] Example 2, as Figures 22-33As shown, this embodiment has a structure largely the same as that of Embodiment 1, with identical components using the same reference numerals. The only difference is that in Embodiment 1, the top end of the A-frame adjustment mechanism 100 is fixed to the first plate 200, and the height and horizontal position are adjusted by sliding the bottom end of the A-frame adjustment mechanism 100. In Embodiment 2, both the top and bottom ends of the A-frame adjustment mechanism 100 can slide, and the height is adjusted by sliding the bottom end of the A-frame adjustment mechanism 100, while the horizontal displacement is adjusted by sliding the top end. This division of labor for different displacement adjustments, and the bottom adjustment only uses one fourth adjustment component 54, resulting in a compact structure and convenient adjustment.

[0167] like Figure 22 and Figure 23 As shown, the adjustment mechanism 100 includes: a first slide rail 31, a second slide rail 32, a third slide rail 33, a first connecting member 11, a second connecting member 12, a third connecting member 13, a first support rod 21, a second support rod 22, a third adjusting member 53, and a fourth adjusting member 54, and all components of the adjustment mechanism 100 are made of steel.

[0168] The first track portion 312 of the first slide rail 31 is located on the bottom surface of the first plate 200 and is parallel to the edge of the second plate 300. The length of the first connecting member 11 is less than the length of the first track portion 312. The first slider 111 of the first connecting member 11 can slide along the length direction of the first track portion 312. The third adjusting member 53 includes a third screw section 531, a third bearing portion 532, and a third nut portion 533. The first slider 111 of the first connecting member 11 is provided with a third adjusting hole 1111 (threaded hole). The third screw section 531 passes through the third adjusting hole 1111. One end of the first track portion 312 is provided with a third bearing hole with a cross-section larger than that of the first arc portion 3111. The third bearing portion 532 fits into the third bearing hole. The two ends of the first track portion 312 are fixed with two first end plates 313 by screws. One of the first end plates 313 is provided with a third through hole. The third nut portion 533 passes through the third through hole and extends to the outside of the first track.

[0169] The second track portion 322 of the second slide rail 32 and the third track portion 332 of the third slide rail 33 are fixed to the top surface of the second plate 300. The second track portion 322 and the third track portion 332 are symmetrically arranged on each side of the second plate 300, with a certain distance in the middle, that is, the second track portion 322 and the third track portion 332 are separate parts.

[0170] The fourth adjusting member 54 consists of five sections: a fourth screw section 541, a fifth screw section 542, two fourth bearing sections 543, and a fourth nut section 544. The threads of the fourth screw section 541 and the fifth screw section 542 are respectively matched with the threaded holes of the second connecting member 12 and the third connecting member 13. The two fourth bearing sections 543 are disc-shaped bearings and are located between the fourth screw section 541 and the fifth screw section 542 to fix the fourth adjusting member 54. The diameter of the fourth bearing section 543 is larger than the circular diameter of the second slider 121 and the third slider 131. The fourth nut section 544 is located between the two fourth bearing sections 543 for rotating the fourth adjusting member 54 with a wrench. During assembly, the two fourth bearing sections 543 of the fourth adjusting member 54 are fixed between the second slide rail 32 and the third slide rail 33, and the fourth screw section 541 and the fifth screw section 542 are respectively inserted into the threaded holes of the second connecting member 12 and the third connecting member 13.

[0171] The following reference Figures 24-33 The assembly process of the adjusting support 103 in this embodiment 2 is described.

[0172] 1) Install the four second connectors 12 and the four third connectors 13 onto the fourth screw section 541 and the fifth screw section 542 of the four fourth adjusting members 54, respectively, as follows: Figure 25 As shown; 2) Install four second track sections 322 onto four second connectors 12, and install four third track sections 332 onto four third connectors 13, as shown.

Figure 33 As shown.

[0173] The following describes the adjustment method of the adjustable foundation 1000 of the transmission tower in this embodiment 2.

[0174] 1) After discovering that the displacement of the adjustable foundation 1000 of the transmission tower exceeds the limit, determine the displacement adjustment value of the adjustable foundation 1000 of the transmission tower.

[0175] 2) Use jack 3000 for unloading. Place jack 3000 between the second plate 300 and the first plate 200 of the adjusting support 103, and use jack 3000 to lift and partially unload the load, reducing the pressure on the adjusting mechanism 100. Before lifting with jack 3000, loosen connecting bolt 2002.

[0176] 3) Vertical displacement adjustment. Rotate the fourth adjusting component 54 with a wrench to control the horizontal sliding of the second connecting component 12 and the third connecting component 13, so that the included angle between the first support rod 21 and the second support rod 22 changes, thereby adjusting the height of the A-frame brace adjusting mechanism 100, which can achieve the purpose of adjusting the height of the adjusting support 103.

[0177] Horizontal displacement adjustment. By turning the third adjusting member 53 with a wrench, the first connecting member 11 is controlled to slide horizontally relative to the first plate 200, and the horizontal position of the A-frame brace adjusting mechanism 100 is adjusted, thereby achieving the purpose of adjusting the horizontal displacement of the first plate 200 of the adjusting support 103.

[0178] Tilt displacement adjustment. Rotate the fourth adjusting member 54 with a wrench to control the horizontal sliding of the second connecting member 12 and the third connecting member 13, so that the included angle of the first support rod 21 and the second support rod 22 changes, thereby adjusting the height of the A-frame brace adjusting mechanism 100. By controlling the height adjustment values ​​of the four A-frame brace adjusting mechanisms 100 to be inconsistent, the purpose of adjusting the relative tilt of the first plate 200 and the second plate 300 of the adjusting support 103 can be achieved.

[0179] Torsional displacement adjustment. By turning the third adjusting member 53 with a wrench, the first connecting member 11 is controlled to slide horizontally relative to the first plate 200. The horizontal position of the four A-frame support adjusting mechanisms 100 is adjusted to move clockwise or counterclockwise in sync, thereby achieving the purpose of adjusting the horizontal rotation of the first plate 200 of the adjusting support 103.

[0180] 4) Tighten the support assembly 400. After adjusting the displacement of the support 103 into place, tighten the bottom wedge 401 and the middle wedge 402 so that the vertical load is mainly borne by the support assembly 400, and tighten the connecting bolts 2002.

[0181] 5) Remove jack 3000. Unload jack 3000. At this time, the vertical load is mainly borne by support component 400, and jack 3000 can be removed.

[0182] According to the above two embodiments of the present invention, the adjustable foundation 1000 of the transmission tower has an all-directional adjustment function, that is, it has the adjustment function of six spatial displacements, namely linear displacement in the X, Y, and Z directions and angular displacement in the X, Y, and Z directions. It can meet the requirements of adjusting the column base 2001 of the transmission tower 2000 after any displacement of the foundation of the transmission tower 2000. It also has a large displacement adjustment function, with the linear displacement adjustment amplitude reaching more than 100 mm and the horizontal tilt angular displacement adjustment amplitude reaching more than 3 degrees.

[0183] The adjustable foundation 1000 for transmission towers in this embodiment of the invention incorporates four support components 400 within the adjusting support 103 to bear the vertical load under normal operating conditions. This results in both the foundation and the adjusting support 103 possessing extremely high vertical bearing capacity, exceeding 10,000 kN, meeting the vertical bearing capacity requirements of large transmission towers such as UHV transmission towers 2000. The adjustable foundation 1000 of this invention possesses sufficient lateral and uplift bearing capacity. The adjusting mechanism 100 of the adjusting support 103 is in the shape of a V-brace. The V-brace is a geometrically invariant structure, possessing not only a large vertical bearing capacity but also significant lateral bearing capacity and lateral stiffness. The V-brace also has a large tensile bearing capacity, meeting the uplift resistance requirements of the transmission tower 2000 under extreme loads (such as strong wind loads and large eccentric forces on angle towers).

[0184] The adjustable foundation 1000 of this invention provides a function for temporarily unloading pressure under the base of the transmission tower 2000 during foundation displacement adjustment. An unloading jack 3000 can be arranged at the center of the adjusting support 103. During foundation adjustment, the jack 3000 is used to first unload the pressure under the base of the transmission tower 2000 before adjustment. This facilitates displacement adjustment and ensures the safe operation of the transmission tower 2000. All displacement adjustment components of the adjustable foundation 1000 of this invention are traditional and simple mechanical structures. The adjusting support 103 has good reliability and durability, ensuring long-term safe and reliable use.

[0185] The concrete column 102 of the adjustable foundation 1000 for transmission towers of this invention is prefabricated in a factory and integrated with the adjusting support 103, forming a standardized product. This ensures the quality of both the column and the adjusting support 103, and facilitates standardization and versatility of the foundation and the adjusting support 103, avoiding installation difficulties and inaccuracies caused by on-site installation of the adjusting support 103. Simultaneously, the concrete foundation 101 is constructed using a cast-in-place on-site process, and the concrete column 102 and the concrete foundation 101 are connected by post-cast concrete overlap, adaptable to foundations of different sizes, and exhibiting good versatility.

[0186] Therefore, the adjustable foundation 1000 of the transmission tower in this embodiment can provide a scientific, reasonable, safe and reliable all-directional adjustable foundation technical solution for the transmission tower 2000 in geological disaster areas.
