Description

Technical Field

[0001] This invention relates to the field of power transmission tower correction and alignment, specifically to a general system and method for power transmission tower correction and alignment. Background Technology

[0002] In recent years, the country has vigorously promoted the West-to-East Power Transmission Project, transmitting electricity from multiple energy bases in the west to the more economically developed regions in the east. At the same time, the intensive mining of coal resources has created large areas of coal mine subsidence, inevitably surrounding power transmission line towers within these affected areas. Several power transmission lines of different voltage levels in my country already pass through coal mine subsidence areas, including the first ultra-high voltage (UHV) pilot demonstration project, the "Southeast Shanxi-Nanyang-Jingmen 1000kV AC transmission line."

[0003] Currently, several tower foundations in power transmission lines built in coal mine goaf areas have experienced subsidence and tilting accidents. The process from deformation to failure in a coal mine goaf is lengthy and complex. After mining, large areas of goaf and roadways are left behind. The overlying rock strata lose their support, and the surrounding rock mass loses its original equilibrium, resulting in bending, fracture, and collapse, leading to ground subsidence and collapse. Affected by surface subsidence in the goaf, the foundations of power transmission line towers will experience subsidence and tilting, further causing uneven subsidence and tilting of the towers, directly threatening the safety of the towers and the stable operation of the lines. Furthermore, the same mining area often contains multiple coal seams, requiring multiple mining and recovery operations; each coal seam mining operation has the potential to impact the power transmission line towers.

[0004] To address the issue of tilted transmission towers, compared to modifying the transmission line and rebuilding the tower, correction and adjustment can effectively reduce construction time and workload, lower costs, and sometimes can be carried out without power outages, offering numerous advantages. Currently, tilted transmission line towers are mainly corrected by using cranes in conjunction with raising the base surface: before formal construction, specialized tools are used to loosen the anchor nuts, and then cranes and other equipment are used to raise the tower legs that are below the reference surface. Afterward, the gap between the tower legs and the foundation is filled to achieve the purpose of leveling the tower.

[0005] However, existing crane alignment technology has the following significant technical problems: On the one hand, crane operation is difficult, requiring high levels of skill from the construction environment and operators, and each alignment requires a long power outage, making live operation impossible and seriously affecting the normal power supply of transmission lines; on the other hand, crane rental costs are high, requiring a separate crane to be rented for each alignment, resulting in high alignment costs; at the same time, existing alignment devices lack versatility and reusability, making it difficult to adapt to the alignment needs of different types of towers, and unable to meet the multiple alignment scenarios caused by repeated mining of coal seams in goaf areas, thus limiting their practicality. Summary of the Invention

[0006] The purpose of this invention is to solve the problems of high difficulty in correcting the alignment of existing power transmission towers, long power outage time, high correction cost, and difficulty in meeting the needs of multiple corrections.

[0007] The objective of this invention is achieved through the following technical solution: A general-purpose system for correcting and adjusting the alignment of power transmission towers includes: The tower leg lifting unit includes a tower leg connecting plate and a tower leg clamp. The tower leg connecting plate is detachably connected to the inherent bolt holes of the tower leg and tower foot plate of the transmission tower. The tower leg clamp is detachably connected to the tower leg connecting plate. A lifting power unit is positioned below the tower leg clamp to lift the tower leg clamp; The replacement component is placed between the tower leg plate and the foundation of the transmission tower. By combining the tower leg lifting unit, the lifting power unit and the replacement component, it eliminates the need for large cranes, reducing operational difficulty and correction costs, adapting to different towers and meeting multiple correction requirements.

[0008] Optionally, the tower leg connecting plate includes a horizontal connecting plate and a vertical connecting plate that are perpendicularly connected to each other. The horizontal connecting plate is detachably connected to the tower leg clamp, and the vertical connecting plate is provided with a first type of through hole, which is detachably connected to some of the inherent bolt holes. The vertical design of the horizontal and vertical connecting plates and the adaptability of the first type of through hole enable a stable connection between the tower leg connecting plate and the tower, improving the system's versatility and assembly flexibility.

[0009] Optionally, the vertical connecting plate is further provided with a second type of through hole corresponding to the position of some of the inherent bolt holes, and the diameter of the second type of through hole is larger than the outer diameter of the inherent nut connected by the inherent bolt hole; When the first type of through hole connects to some of the inherent bolt holes, the second type of through hole is fitted onto the outside of the inherent nuts connected to the remaining inherent bolt holes. This avoidance design of the second type of through hole eliminates the need to remove all inherent nuts, simplifying the construction process while retaining some inherent bolts, which also helps enhance connection stability.

[0010] Optionally, the tower leg connecting plate further includes a longitudinal connecting plate that is perpendicularly connected to the horizontal connecting plate and the vertical connecting plate; The tower leg clamp includes a clamp horizontal plate and a clamp vertical plate that are perpendicularly connected to each other. The clamp horizontal plate is detachably connected to the horizontal connecting plate, and the clamp vertical plate is detachably connected to the vertical connecting plate. The tower leg lifting unit includes at least one tower leg connecting plate and at least two tower leg clamps. The clamping longitudinal plates of the two tower leg clamps are symmetrically clamped on both sides of the longitudinal connecting plate of one tower leg connecting plate. The longitudinal connecting plate and the symmetrically clamped tower leg clamps cooperate to form a three-dimensional force-bearing structure, so that the lifting force is evenly distributed and local force concentration is avoided.

[0011] Optionally, the tower leg lifting unit further includes at least two lifting pads; The tower leg clamp also includes a clamp rib plate that is perpendicularly connected to the clamp horizontal plate and the clamp vertical plate, and the two lifting pads are detachably connected to the clamp rib plates of the two tower leg clamps. The lifting power unit includes at least two jacks, which lift the two lifting blocks respectively. The upper and lower surfaces of the lifting blocks are not parallel. The upper surface of the lifting block is in contact with the bottom surface of the clamp rib when tilted, and the lower surface of the lifting block is in contact with the top surface of the jack when horizontal. The non-parallel design of the lifting blocks can adapt to tilted towers, and the synchronous lifting of the two jacks can improve lifting stability and control accuracy.

[0012] Optionally, the lifting power unit further includes at least two support platforms to support the two jacks respectively; The general-purpose correction system also includes an anti-tipping unit, which includes at least two pads, which are respectively placed on the bottom of the two supports and detachably connected to the bottom of the supports. The lower part of the jack is fixed in the protective shell, and the bottom of the protective shell is detachably connected to the top of the support platform by bolts. The combination of the support platform and the pad plate can limit the lateral displacement of the jack, prevent overturning, and at the same time distribute pressure to adapt to various ground conditions.

[0013] Optionally, the anti-overturning unit further includes at least two sets of sleepers, which are respectively laid under the two pads; The anti-overturning unit also includes at least two connecting beams that connect the two pads from both sides of the foundation. By distributing pressure with sleepers and fixing the pads with connecting beams, a complete anti-overturning unit can be formed, thereby improving the overall stability of the system and its adaptability to different foundation sizes.

[0014] Optionally, the number of the support components is at least two. Each support component is provided with a U-shaped groove and a connecting plate. The U-shaped groove is through which anchor bolts connecting the tower base plate to the foundation are inserted, and the connecting plate connects adjacent support components. The design of the U-shaped groove facilitates the side installation of the support components, and the connecting plate enables combination and splicing, allowing for precise adjustment of the lifting height.

[0015] Based on the same inventive concept, this invention also provides a general method for correcting and adjusting the alignment of transmission towers, including: Remove some of the inherent bolts and nuts at the connection between the tower leg and the tower foot plate of the transmission tower, and detachably connect the tower leg connecting plate to the inherent bolt holes where the inherent bolts have been removed; The tower leg clamp is detachably connected to the tower leg connecting plate, and a lifting power unit is installed below the tower leg clamp; The lifting power unit controls the lifting leg clamps, which in turn drive the tower legs and tower foot plates to lift synchronously through the leg clamps and the connecting plate. When the tower foot plate is raised to the preset height, the supporting components will be placed between the tower foot plate and the foundation of the transmission tower. The pressure of the lifting power unit is controlled to allow the tower foot plate to rest on the support structure. By establishing a standardized process for bolt replacement, lifting, and support, the correction period can be effectively shortened and the impact on the power supply of the transmission line can be reduced.

[0016] Optionally, general methods for correcting and adjusting the alignment of transmission towers include: Sleepers are laid on both sides of the foundation of the tower leg of the transmission tower to be corrected, and pads are placed on the sleepers. The two pads are then connected and fixed by a connecting beam. Install the support plate on the base plate and fix it with bolts. Place the jack in the slot of the support plate. Adjust the working height of the jack by stacking support plates of different heights. Remove some of the inherent bolts and nuts at the connection between the tower leg and the tower foot plate, while retaining some of the inherent bolts and nuts. Use high-strength bolts to connect the first type of through hole in the tower leg connecting plate to the inherent bolt hole where the inherent bolts have been removed. At this time, the retained inherent nuts are inserted into the second type of through hole in the tower leg connecting plate. Two tower leg clamps are symmetrically clamped on both sides of the longitudinal connecting plate of the tower leg connecting plate, so that the horizontal plate of the clamp is bolted to the horizontal connecting plate and the longitudinal plate of the clamp is bolted to the longitudinal connecting plate. A lifting pad is connected below the clamp rib plate so that the lower surface of the lifting pad is in contact with the top surface of the jack. Loosen the nuts of the anchor bolts between the tower leg plate and the foundation, and control the two jacks to lift the lifting pads, thereby driving the tower leg lifting unit, tower leg and tower leg plate to lift synchronously; When the tower foot plate is raised to the preset height, two supporting components are placed between the tower foot plate and the foundation, and adjacent supporting components are connected by butt plate bolts. At this time, the U-shaped groove of the supporting component is sleeved on the outside of the anchor bolt. Slowly release the pressure from the jacks, allowing the tower leg plate to rest on the supporting structure. Tighten the nuts on the anchor bolts, then disconnect the tower leg lifting unit from the tower leg, completing the correction and alignment of the transmission tower. The installation of the anti-overturning unit and the overlapping adjustment of the pier cap further enhance construction safety and the accuracy of lifting height control, ensuring the quality of the correction.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides a universal system for correcting and adjusting the alignment of transmission towers, comprising: a tower leg lifting unit, including a tower leg connecting plate and a tower leg clamp, wherein the tower leg connecting plate is detachably connected to some inherent bolt holes of the tower leg and the tower foot plate of the transmission tower, and the tower leg clamp is detachably connected to the tower leg connecting plate; a lifting power unit, disposed below the tower leg clamp to lift the tower leg clamp; and a support component, which is placed between the tower foot plate and the foundation of the transmission tower.

[0018] This invention, by detachably connecting the tower leg connecting plate to some of the inherent bolt holes of the tower legs and base plates of the transmission tower, eliminates the need for additional drilling or welding on the tower. This enables compatibility with different types of transmission towers, improving system versatility while avoiding damage to the original tower structure and ensuring its structural integrity. Furthermore, the detachable connection between the tower leg clamp and the tower leg connecting plate creates a stable force-bearing structure for tower leg lifting, allowing the lifting force to be evenly distributed to the tower legs and base plates, preventing localized stress concentration and improving the stability and safety of the tower leg lifting process. A lifting power unit is installed below the tower leg clamp, which can lift the tower legs without relying on external equipment such as large cranes. This reduces the difficulty of operation and the cost of equipment rental. At the same time, it can carry out live work without long-term power outages, reducing the impact on the normal power supply of transmission lines. By padding the tower leg plate with a replacement component between the tower leg plate and the foundation, the lifted tower leg plate can be accurately supported, enabling rapid leveling of the tower. The replacement component can be flexibly combined according to the lifting height to adapt to different correction needs. In addition, the components of the system can be disassembled and reused to meet the needs of multiple correction scenarios in goaf areas. Attached Figure Description

[0021] Due to the repeated mining and recovery of coal seams, the ground experiences multiple subsidence and collapses, leading to repeated tilting accidents of power transmission towers. Therefore, the method for correcting the tilt of power transmission towers in goaf areas should adhere to the principle of facilitating multiple tilt correction and treatment. In this regard, this invention proposes a universal system and method for correcting the tilt of power transmission towers, which is highly suitable for the repeated tilt correction and treatment of power transmission towers.

[0025] Example 1 like Figures 1-23 As shown, the present invention provides a universal system for correcting and adjusting the alignment of power transmission towers, comprising: The tower leg lifting unit 2 includes a tower leg connecting plate 21 and a tower leg clamp 22. The tower leg connecting plate 21 is detachably connected to the inherent bolt holes of the tower leg 11 and the tower foot plate 12 of the transmission tower 1. The tower leg clamp 22 is detachably connected to the tower leg connecting plate 21. The lifting power unit 3 is positioned below the tower leg clamp 22 to lift the tower leg clamp 22; The replacement component 4 is placed between the tower foot plate 12 and the foundation 13 of the transmission tower 1.

[0026] In practice, the tower leg connecting plate 21 is connected via the existing bolt holes on the tower leg 11 and tower foot plate 12 of the transmission tower 1. When bolt connection is used, the bolts pass through the tower leg connecting plate 21 and the existing bolt holes to achieve a stable assembly. The connection between the tower leg clamp 22 and the tower leg connecting plate 21 can also be achieved by bolt connection, with the bolts passing through the corresponding connecting holes to complete the assembly, facilitating subsequent disassembly or adjustment.

[0027] The lifting power unit 3 is located below the tower leg clamp 22. Its core function is to provide upward lifting force. It can be equipped with power components such as jacks 31, which directly act on the bottom of the tower leg clamp 22 through power output, driving the entire tower leg lifting unit 2 to move upward. The support component 4 is a support structure with a certain load-bearing capacity. After the tower leg 11 is lifted, it is placed between the tower foot plate 12 and the foundation 13 to bear the load transmitted by the tower foot plate 12 and maintain the horizontal state of the transmission tower 1.

[0028] During the correction and alignment process, firstly, the tower leg connecting plate 21 is connected and fixed to the inherent bolt holes of the tower leg 11 and the tower foot plate 12. Then, the tower leg clamp 22 is assembled with the tower leg connecting plate 21. The lifting power unit 3 is started, and the lifting force generated by it is transmitted to the tower leg 11 and the tower foot plate 12 through the tower leg clamp 22 and the tower leg connecting plate 21, driving the tower leg 11 to rise until the tower foot plate 12 reaches the preset horizontal height. Finally, the replacement component 4 is inserted between the tower foot plate 12 and the foundation 13, so that the replacement component 4 fully bears the weight of the tower foot plate 12, thus completing the correction and alignment of the transmission tower 1.

[0029] Existing solutions use cranes to raise the base surface for leveling and correction, relying on large crane equipment to lift the tower legs. This invention, through the combined design of the tower leg lifting unit 2, the lifting power unit 3, and the support component 4, forms a dedicated correction system independent of the crane, which can complete the tower leg lifting and correction operations without relying on a large crane.

[0030] The tower leg lifting unit 2 of this invention connects to the inherent bolt holes of the tower leg 11 and the tower foot plate 12, simplifying the assembly process and eliminating the need for complex equipment operations, thus reducing operational difficulty. The entire system is relatively compact, has low requirements for the construction environment, and does not require a large construction space, further enhancing the convenience of on-site construction. The assembly and lifting process of this system does not require prolonged power outages and can be carried out while the power is on, reducing the impact on the normal power supply of transmission lines and solving the problem of long power outage times in existing solutions. Except for the replacement component 4, all components of this system are reusable, eliminating the need to rent large cranes for each correction, significantly reducing equipment investment costs during the correction process and solving the problem of high correction costs in existing solutions. The connection between the tower leg connecting plate 21 and the tower leg 11 and the tower foot plate 12 of this invention is based on the inherent bolt holes, which is compatible with the conventional structural design of different types of transmission towers 1 and has strong versatility. It can meet the correction requirements of transmission towers 1 with different voltage levels and different structural forms. At the same time, the detachable connection design of the system facilitates disassembly and reassembly, and can adapt to the multiple correction scenarios caused by repeated mining of coal seams in goaf areas, thereby improving practicality.

[0031] Furthermore, the tower leg connecting plate 21 includes a horizontal connecting plate 211 and a vertical connecting plate 212 that are perpendicularly connected to each other. The horizontal connecting plate 211 is detachably connected to the tower leg clamp 22. The vertical connecting plate 212 is provided with a first type of through hole 2121, which is detachably connected to some of the inherent bolt holes.

[0032] In practical implementation, the tower leg connecting plate 21 adopts a structure in which horizontal connecting plate 211 and vertical connecting plate 212 are perpendicularly connected to each other. The two can be fixed by welding, integral molding, or other methods to ensure connection strength and structural stability. The horizontal connecting plate 211 is provided with connecting holes for detachable connection with the tower leg clamp 22. The number and position of the connecting holes can be designed according to the assembly requirements of the tower leg clamp 22. Bolts are passed through these connecting holes to connect with the corresponding holes of the tower leg clamp 22 to achieve a stable assembly of the two.

[0033] The first type of through hole 2121 on the vertical connecting plate 212 is adapted to the inherent bolt holes of the tower leg 11 and the tower foot plate 12. If the inherent bolt holes of the tower leg 11 and the tower foot plate 12 are evenly distributed along the length of the vertical connecting plate 212, the first type of through hole 2121 also adopts the same distribution spacing to ensure that each first type of through hole 2121 can be precisely aligned with the corresponding inherent bolt hole. The shape of the first type of through hole 2121 can be designed as a circular hole according to actual needs (e.g., Figure 7 (as shown) or a slotted hole (such as Figure 5 , 6 As shown in Figure 8, if a strip hole is used, the connection position can be adjusted within a certain range to accommodate the slight deviation of the inherent bolt hole position and improve the flexibility of assembly.

[0034] In practical use, the vertical connecting plate 212 is attached to the connecting surface of the tower leg 11 and the tower foot plate 12, so that the first type of through hole 2121 corresponds one-to-one with the inherent bolt hole. The vertical connecting plate 212 is fixedly connected to the tower leg 11 and the tower foot plate 12 by bolts passing through the first type of through hole 2121 and the inherent bolt hole. Then, the tower leg clamp 22 is connected to the horizontal connecting plate 211 by bolts, so that the tower leg clamp 22 and the tower leg connecting plate 21 form a stable whole, providing a reliable structural foundation for the subsequent transmission of lifting power.

[0035] In existing solutions, crane alignment does not involve a dedicated tower leg connecting plate 21 structure; it simply lifts the tower leg 11 directly by crane, lacking a targeted connection and force transmission structure. The difference between the technical solution of this invention and the existing solution lies in the design of a tower leg connecting plate 21 structure in which the horizontal connecting plate 211 and the vertical connecting plate 212 are perpendicular to each other, and the first type of through hole 2121 on the vertical connecting plate 212 is adapted to the inherent bolt hole, specifically for achieving a precise connection between the tower leg connecting plate 21 and the tower leg 11 and the tower foot plate 12.

[0036] The vertical structure design of the horizontal connecting plate 211 and the vertical connecting plate 212 enables the tower leg connecting plate 21 to form a stable connection with both the tower leg 11 and the tower foot plate 12, dispersing the force during the lifting process and preventing excessive local stress that could lead to structural damage. The adaptability design of the first type of through hole 2121 ensures the compatibility of the tower leg connecting plate 21 with the inherent bolt holes of different transmission towers 1, improving the system's versatility. The design of the strip hole further enhances the flexibility of assembly, enabling it to cope with minor deviations in the position of the inherent bolt holes during construction and reducing assembly difficulty.

[0037] Furthermore, the vertical connecting plate 212 is also provided with a second type of through hole 2122 corresponding to the position of some of the inherent bolt holes. The diameter of the second type of through hole 2122 is larger than the outer diameter of the inherent nut connected by the inherent bolt holes. When the first type of through hole 2121 is connected to part of the inherent bolt holes, the second type of through hole 2122 is fitted onto the outside of the inherent nut connected to the remaining inherent bolt holes.

[0038] In specific implementation, such as Figures 11-12 As shown, the connection between the tower leg 11 and the tower base plate 12 is provided with 18 inherent bolts and nuts. Nine inherent bolts and nuts can be removed, leaving the remaining nine. Therefore, nine first-type through holes 2121 can be provided on the vertical connecting plate 212, corresponding to the nine inherent bolt holes after the inherent bolts are removed. Similarly, nine second-type through holes 2122 can be provided, corresponding to the positions of the nine retained inherent nuts.

[0039] The through holes at the bottom of the tower leg connecting plate 21 can be divided into two categories: the first type 2121 (small through hole) and the second type 2122 (large through hole). The small through hole is used to connect with the original bolt holes on the tower leg 11 and the tower foot plate 12, and is fixed by passing a high-strength bolt through the small through hole. The large through hole is used to pass through the original nut at the connection between the tower foot plate 12 and the tower leg 11. There is no need to remove the original nut; simply passing it through the large through hole completes the assembly of the tower leg connecting plate 21. The connecting holes on the upper wing plate (i.e., the horizontal connecting plate 211) of the tower leg connecting plate 21 are used for connection with the tower leg clamp 22 to realize the overall assembly of the tower leg lifting unit 2.

[0040] During assembly, the vertical connecting plate 212 is attached to the connecting surface of the tower leg 11 and the tower foot plate 12, and the second type of through hole 2122 is aligned with the nine reserved inherent nuts. The inherent nuts are then passed through the second type of through hole 2122, at which point a portion of the vertical connecting plate 212 is attached to the connecting surface of the tower leg 11 and the tower foot plate 12. Next, the nine high-strength bolts are passed through the first type of through hole 2121 respectively, connected to the corresponding inherent bolt holes and tightened, completing the fixed assembly of the tower leg connecting plate 21 with the tower leg 11 and the tower foot plate 12. Finally, the horizontal connecting plate 211 is connected to the tower leg clamp 22 through the connecting hole to form a complete force transmission structure.

[0041] Existing solutions for crane alignment do not involve the tower leg connecting plate 21 with this type of double-through-hole structure. Alignment is achieved simply by directly lifting the tower leg 11, without considering the avoidance of inherent nuts or the retention of some bolts. The difference between the technical solution of this invention and the existing solution is that by setting first-type through-holes 2121 and second-type through-holes 2122 of different sizes and functions on the vertical connecting plate 212, some inherent bolts can be replaced and some inherent nuts can be avoided, without completely removing all bolts and nuts at the connection between the tower leg 11 and the tower foot plate 12.

[0042] The design of the second type of through hole 2122 allows for the avoidance of inherent nuts, enabling the assembly of the tower leg connecting plate 21 to be completed without removing all inherent nuts, thus simplifying the construction process. The retention of some inherent bolts and nuts, together with the newly added high-strength bolts, enhances the connection strength between the tower leg connecting plate 21 and the tower leg 11 and tower foot plate 12, improving the structural stability during the lifting process. The design of the number and position of the first type of through hole 2121 and the second type of through hole 2122 precisely matches the conventional bolt distribution of the tower leg 11 and tower foot plate 12, ensuring the adaptability and versatility of the structure.

[0043] Furthermore, the tower leg connecting plate 21 also includes a longitudinal connecting plate 213 that is perpendicularly connected to the horizontal connecting plate 211 and the vertical connecting plate 212; The tower leg clamp 22 includes a clamp horizontal plate 221 and a clamp vertical plate 222 that are perpendicularly connected to each other. The clamp horizontal plate 221 is detachably connected to the horizontal connecting plate 211, and the clamp vertical plate 222 is detachably connected to the vertical connecting plate 213. The tower leg lifting unit 2 includes at least one tower leg connecting plate 21 and at least two tower leg clamps 22. The clamping longitudinal plates 222 of the two tower leg clamps 22 are symmetrically clamped on both sides of the longitudinal connecting plate 213 of one tower leg connecting plate 21.

[0044] In specific implementation, the tower leg connecting plate 21 adds a longitudinal connecting plate 213 to the horizontal connecting plate 211 and the vertical connecting plate 212. The longitudinal connecting plate 213 is perpendicularly connected to the horizontal connecting plate 211 and the vertical connecting plate 212 respectively. The three can be welded or integrally formed to form a stable three-dimensional structure (such as...). Figure 8 As shown, the tower leg connecting plate 21 enhances the overall rigidity and load-bearing capacity. The tower leg clamp 22 is composed of clamp horizontal plate 221 and clamp vertical plate 222 connected perpendicularly to each other. It can also be manufactured by welding or integral molding process to ensure structural strength.

[0045] The clamp horizontal plate 221 has connecting holes corresponding to the horizontal connecting plate 211, and the two are detachably connected by bolts; the clamp vertical plate 222 has connecting holes corresponding to the vertical connecting plate 213, and the two are detachably connected by bolts. The tower leg lifting unit 2 includes at least one tower leg connecting plate 21 and at least two tower leg clamps 22 (e.g., Figure 4 As shown), the clamping longitudinal plates 222 of the two tower leg clamps 22 are symmetrically clamped on both sides of the longitudinal connecting plate 213 of the tower leg connecting plate 21, forming a symmetrical clamping structure.

[0046] The form of the tower leg connecting plate 21 can be designed in various styles according to actual needs: in addition to a three-dimensional structure including a horizontal connecting plate 211, a vertical connecting plate 212, and a longitudinal connecting plate 213, it can also be designed as an L-shaped structure including only the horizontal connecting plate 211 and the vertical connecting plate 212 (such as...). Figure 5 , 7 As shown, this is suitable for scenarios with relatively small forces, or another L-shaped structure consisting only of the longitudinal connecting plate 213 and the vertical connecting plate 212 (as shown). Figure 6 (As shown). The number of tower leg connecting plates 21 can be adjusted to 2 according to the force requirements, and the number of tower leg clamps 22 can be adjusted to 4 according to the force requirements (e.g. Figure 3 As shown in the figure, this further improves the uniformity of stress distribution and load-bearing capacity.

[0047] In practical use, the clamping longitudinal plates 222 of the two tower leg clamps 22 are respectively attached to both sides of the longitudinal connecting plate 213, aligning the connecting holes on the clamping longitudinal plates 222 with the corresponding holes on the longitudinal connecting plate 213, and then tightened with bolts; at the same time, the connecting holes on the clamping transverse plates 221 are aligned with the connecting holes on the transverse connecting plate 211, and then tightened with bolts, achieving a stable connection between the tower leg clamps 22 and the tower leg connecting plate 21. The symmetrical clamping structure enables the tower leg lifting unit 2 to evenly transmit force during the stress process, avoiding structural deformation or displacement caused by excessive force on one side.

[0048] In existing solutions, the crane's alignment does not employ this multi-plate connection and symmetrical clamping tower leg lifting unit 2 structure. Instead, the crane hook directly applies force to the tower leg 11, resulting in a single and unstable force point. The difference between the present invention and existing solutions lies in the design of a tower leg connecting plate 21 containing a longitudinal connecting plate 213 and a tower leg clamp 22 composed of a clamping horizontal plate 221 and a clamping vertical plate 222. Through a symmetrical clamping assembly method, a structurally stable tower leg lifting unit 2 is formed, achieving uniform force transmission.

[0049] The addition of the longitudinal connecting plate 213 enables the tower leg connecting plate 21 to form a three-dimensional structure, which greatly improves the structural rigidity and load-bearing capacity, and can withstand the longitudinal and lateral forces during the lifting process. The symmetrical clamping design of the tower leg clamp 22 ensures that the force is evenly transferred from the tower leg clamp 22 to the tower leg connecting plate 21, and then to the tower leg 11 and the tower foot plate 12, avoiding localized force concentration and improving the stability of the lifting process. The various structural designs of the tower leg connecting plate 21 can be flexibly selected according to different stress scenarios and assembly space, enhancing the adaptability of the system.

[0050] Furthermore, the tower leg lifting unit 2 also includes at least two lifting pads 23; The tower leg clamp 22 also includes a clamp rib 223 that is perpendicularly connected to the clamp horizontal plate 221 and the clamp vertical plate 222, and two lifting pads 23 are detachably connected to the clamp rib 223 of the two tower leg clamps 22. The lifting power unit 3 includes at least two jacks 31, which lift two lifting pads 23 respectively. The upper and lower surfaces of the lifting pads 23 are not parallel. The upper surface of the lifting pads 23 is in contact with the bottom surface of the clamp rib 223 when it is tilted, and the lower surface of the lifting pads 23 is in contact with the top surface of the jacks 31 when it is horizontal.

[0051] In specific implementation, the jack 31 of the lifting power unit 3 can be a servo jack. Servo jacks are characterized by high control precision and stable lifting force, and can accurately control the lifting height and lifting speed. The lifting pad 23 is a trapezoidal block with an inclined surface at the top and a horizontal surface at the bottom, making the upper and lower surfaces non-parallel. The slope below the change of slope of different towers 1 is different. Therefore, the inclination degree of the upper inclined surface of the lifting pad 23 needs to be customized according to the slope below the change of slope of the inclined tower 1 to ensure that the upper surface of the lifting pad 23 can fully contact the bottom surface of the clamp rib 223, and the lower horizontal surface can contact the top surface of the jack 31, so as to achieve effective transmission of force.

[0052] The bottom surfaces of the tower legs 11 and the clamping ribs 223 of the tower leg clamps 22 of the inclined transmission tower 1 are inclined. If the upper surface of the lifting pad 23 is horizontal, the contact area between the two will be too small, the force will be concentrated, and it will be easy to cause structural damage or slippage. The inclined design can make the lifting pad 23 and the bottom surface of the clamping ribs 223 fit completely, increase the contact area, disperse the force, and improve the stability and safety of the lifting process.

[0053] In practical use, the two lifting pads 23 are fixed to the bottom of the clamping ribs 223 of the two tower leg clamps 22 with bolts, ensuring that the upper surface of the lifting pads 23 is completely in contact with the bottom surface of the clamping ribs 223; the two jacks 31 are placed under the two lifting pads 23, so that the top surface of the jacks 31 is in contact with the lower surface of the lifting pads 23; the jacks 31 are started, and the lifting force generated by the jacks 31 is transmitted to the clamping ribs 223 through the lifting pads 23, and then to the tower leg connecting plate 21 through the tower leg clamps 22, which ultimately drives the tower leg 11 and the tower foot plate 12 to rise.

[0054] In existing solutions, crane alignment is achieved by directly lifting the tower leg 11 via the crane hook, without the use of dedicated lifting pads 23 and symmetrically distributed jacks 31. This results in unstable force transmission and low control precision. The difference between the present invention and existing solutions lies in the design of lifting pads 23 that are compatible with the clamp ribs 223, and the use of at least two symmetrically distributed jacks 31 for lifting. The inclined surface design of the lifting pads 23 ensures stable force transmission.

[0055] The non-parallel design of the upper and lower surfaces of the lifting pad 23, especially the customized design of the upper inclined surface, can accurately adapt to the bottom surface of the clamp rib plate 223 of the tower 1 with different inclination degrees, solving the problem of unstable force transmission under inclination. The two jacks 31 are symmetrically distributed and lift synchronously to ensure that the lifting force on both sides of the tower leg 11 is uniform and to prevent the tower leg 11 from shifting or tilting during the lifting process. The selection of servo jacks 31 improves the control accuracy of lifting height and speed, enabling precise lifting and meeting the needs of different correction heights.

[0056] Furthermore, the lifting power unit 3 also includes at least two platforms 32, which support the two jacks 31 respectively; The general-purpose correction system also includes an anti-tipping unit 5, which includes at least two pads 51, which are respectively placed on the bottom of two supports 32 and detachably connected to the bottom of the supports 32.

[0057] Preferably, the lower part of the jack 31 is fixed in the protective shell 33, and the bottom of the protective shell 33 is detachably connected to the top of the support platform 32 by bolts.

[0058] In practical implementation, the support platform 32 of the lifting power unit 3 can be designed as a cylindrical frame structure with through holes at the bottom. The pad 51 of the anti-overturning unit 5 can be made of steel plate, which has the characteristics of high strength and strong load-bearing capacity. The pad 51 is provided with bolt holes corresponding to the through holes at the bottom of the support platform 32. The support platform 32 and the pad 51 are detachably connected by bolts passing through the through holes of the support platform 32 and the bolt holes of the pad 51. The top of the support platform 32 can be provided with a circular slot, the size of which is adapted to the bottom size of the jack 31, for placing the jack 31. The circular slot can limit the lateral displacement of the jack 31 during the lifting process, prevent the jack 31 from overturning, and improve construction safety.

[0059] At least two pads 51 of the anti-tipping unit 5 are respectively placed on the bottom of the two bearing platforms 32 and fixedly connected to the bearing platforms 32 by bolts. The pads 51 can increase the contact area between the bearing platform 32 and the ground, distribute the weight of the bearing platform 32 and the jack 31, avoid sinking due to insufficient ground pressure, and further improve the stability of the system.

[0060] Throughout the correction process, the protective shell 33 can be used to protect the jack 31 to prevent it from deviating or being damaged by external impacts during the correction process.

[0061] In practical use, after the construction site is leveled, place the two pads 51 in the preset positions, ensuring that the two pads 51 are symmetrically distributed on both sides of the tower leg 11; place the two bearing platforms 32 on the two pads 51 respectively, aligning the through holes at the bottom of the bearing platforms 32 with the bolt holes on the pads 51, and fasten them with bolts; place the two jacks 31 in the circular slots on the top of the two bearing platforms 32 respectively, ensuring that the jacks 31 are placed stably and will not shift laterally; start the jacks 31 to carry out the lifting operation. The bearing platforms 32 and the pads 51 together provide a stable support foundation for the jacks 31, preventing the jacks 31 from overturning and the ground from sinking.

[0062] In existing solutions, the crane's alignment is not supported by a dedicated support platform 32 and a pad 51. The crane is parked directly on the ground or a simply paved area for operation. This results in a large working area, making it prone to sinking when the ground's bearing capacity is insufficient, and also leads to poor stability during crane operation. The technical solution of this invention differs from the existing solution in that it designs a support platform 32 with a circular groove and a pad 51 for distributing pressure. The detachable connection of these two components forms a stable support system, providing a reliable support foundation for the jack 31 with a smaller working area.

[0063] The circular slot design on the top of the pier 32 can be used to limit the lateral displacement of the jack 31, solving the problem of the jack 31 being prone to tipping over during the lifting process; the detachable connection design between the pier 32 and the pad 51 facilitates transportation and assembly, and the pad 51 increases the contact area, disperses the pressure, and adapts to the construction needs of different ground conditions; the cylindrical frame structure of the pier 32 can reduce its own weight and improve portability while ensuring structural strength.

[0064] Furthermore, the anti-overturning unit 5 also includes at least two sets of sleepers 52, which are laid under the two pads 51 respectively; The anti-overturning unit 5 also includes at least two connecting beams 53, which connect the two pads 51 from both sides of the foundation 13.

[0065] In practical implementation, at least two sets of sleepers 52 of the anti-overturning unit 5 are set up and laid under the two pads 51 respectively. The sleepers 52 can be made of solid wood or composite wood, and have a certain degree of elasticity and load-bearing capacity, which can further disperse the pressure transmitted by the pads 51 and avoid excessive local stress on the ground. The specific structure of the connecting beam 53 can be L-shaped, U-shaped, I-shaped, etc. The pads 51 can have rectangular grooves. The size of the rectangular grooves is adapted to the cross-sectional size of the connecting beam 53. The connecting beam 53 passes through the rectangular grooves of the pads 51 and connects and fixes the two pads 51 from both sides of the foundation 13.

[0066] The connection method of the connecting beam 53 can be adjusted according to actual needs. For example, the connecting beam 53 can be fixed to the pad 51 with bolts, or it can be fixed by welding. For different foundation 13 dimensions, the spacing between the front and rear L-shaped connecting beams 53 can be adjusted to ensure that the connecting beam 53 can adapt to the width of the foundation 13, realize the stable connection of the two pads 51, and form an overall load-bearing structure.

[0067] In practical use, on the leveled construction ground, two sets of sleepers 52 are laid in the preset positions, symmetrically distributed on both sides of the foundation 13. Two pads 51 are placed on the two sets of sleepers 52, and the position of the pads 51 is adjusted to ensure that they correspond to the position of the subsequently installed bearing platform 32. The L-shaped connecting beam 53 is passed through the rectangular groove of the two pads 51. The spacing of the connecting beam 53 is adjusted according to the size of the foundation 13 so that the connecting beam 53 fits against both sides of the foundation 13. The connecting beam 53 is fixedly connected to the pads 51 with bolts so that the two pads 51 form a whole. Subsequently, the bearing platform 32, jacks 31 and other components are installed on the pads 51. The sleepers 52, pads 51 and connecting beams 53 together form a stable anti-overturning foundation to prevent the entire correction system from overturning or shifting during construction.

[0068] In existing solutions, the crane alignment system lacks a dedicated anti-tipping unit 5, relying solely on the crane's own stability. This makes it susceptible to tilting or displacement due to ground conditions and external forces during construction. The difference between this invention and existing solutions lies in the combination of sleepers 52, pads 51, and connecting beams 53 to form a complete anti-tipping unit 5, specifically designed to enhance the overall stability of the alignment system.

[0069] The combined design of sleeper 52 and pad 51 utilizes the elasticity of sleeper 52 to distribute pressure and the rigidity of pad 51 to ensure support strength, adapting to different ground conditions. The matching design of connecting beam 53 and rectangular groove of pad 51 can adjust the spacing according to the size of foundation 13, enhancing the versatility of the system. Connecting beam 53 connects two pads 51 into a whole, improving the overall rigidity and stability of anti-overturning unit 5 and effectively resisting lateral forces during construction.

[0070] Furthermore, the number of replacement components 4 is at least two. Each replacement component 4 is provided with a U-shaped groove 41 and a connecting plate 42. Anchor bolts 14 that connect the tower foot plate 12 to the foundation 13 are inserted through the U-shaped groove 41, and the connecting plate 42 connects adjacent replacement components 4.

[0071] In practical implementation, at least two support components 4 are used. Multiple support components 4 can be combined depending on the correction height and load-bearing requirements. Each support component 4 has a U-shaped groove 41 and a mating plate 42. The U-shaped groove 41 is opened along the length of the support component 4, and its width is greater than the diameter of the anchor bolt 14, ensuring that the support component 4 can be fitted onto the outside of the anchor bolt 14 from the side. The mating plate 42 protrudes from the end of the support component 4 and has bolt holes for connecting adjacent support components 4 by bolts or by welding to form an integral load-bearing structure.

[0072] The supporting components 4 are available in various thicknesses, such as 100mm, 200mm, and 500mm. Different thicknesses of supporting components 4 can be selected or combined and stacked according to the required lifting height of the tower base plate 12 to achieve the preset correction height. For thicker supporting components 4, reinforcing ribs can be installed inside or on the side. These reinforcing ribs are connected to the supporting component 4 body by welding or integral molding to enhance the structural strength and load-bearing capacity of the supporting component 4 and prevent structural deformation caused by its large thickness.

[0073] In practical use, after the tower foot plate 12 is raised to the preset height, the appropriate thickness and number of supporting components 4 are selected according to the distance between the tower foot plate 12 and the foundation 13; the supporting components 4 are inserted from the side between the tower foot plate 12 and the foundation 13, so that the anchor bolts 14 pass through the U-shaped groove 41 of the supporting components 4; adjacent supporting components 4 are connected and fixed with bolts through the bolt holes on the mating plate 42, or fixed by welding, so that multiple supporting components 4 form a whole; the jack 31 is controlled to slowly depressurize, so that the tower foot plate 12 is placed smoothly on the supporting components 4, and the supporting components 4 bear the entire load transmitted by the tower foot plate 12, so as to achieve stable support for the transmission tower 1.

[0074] In existing solutions, crane leveling is achieved by filling the gap between the tower foot and the foundation 13. The filling materials are mostly concrete, gravel, etc., which are not reusable, and the height is difficult to control precisely during the filling process. If subsequent leveling is required, the filling material must be removed again, making the operation cumbersome. The technical solution of this invention differs from the existing solution in that it designs a standardized support component 4, which uses U-shaped grooves 41 to fit anchor bolts 14 and is connected by connecting plates 42. This component is reusable and allows for flexible height adjustment.

[0075] The U-shaped groove 41 of the support component 4 facilitates insertion from the side between the tower foot plate 12 and the foundation 13 without removing the anchor bolts 14, simplifying the assembly process. The combination of support components 4 with various thicknesses allows for precise adjustment of the lifting height of the tower foot plate 12 to meet different correction requirements. The design of the connecting plate 42 enables multiple support components 4 to form a whole, improving load-bearing capacity and stability. The reinforcing ribs enhance the structural strength of the thicker support components 4 and expand their applicability.

[0076] Example 2 Based on the same inventive concept, this invention also provides a general method for correcting and adjusting the alignment of transmission towers, including: Remove some of the inherent bolts and nuts at the connection between the tower leg 11 and the tower foot plate 12 of the transmission tower 1, and detachably connect the tower leg connecting plate 21 to the inherent bolt holes where the inherent bolts have been removed; The tower leg clamp 22 is detachably connected to the tower leg connecting plate 21, and a lifting power unit 3 is installed below the tower leg clamp 22; The lifting power unit 3 controls the lifting leg clamp 22, which in turn drives the tower leg 11 and the tower foot plate 12 to be lifted synchronously through the tower leg clamp 22 and the tower leg connecting plate 21; When the tower foot plate 12 is raised to the preset height, the support component 4 is placed between the tower foot plate 12 and the foundation 13 of the transmission tower 1. The pressure of the lifting power unit 3 is released, so that the tower foot plate 12 is placed on the support component 4.

[0077] Specifically, some of the inherent bolts and nuts at the connection between the tower leg 11 and the tower foot plate 12 can be removed, while some of the inherent bolts and nuts can be retained. High-strength bolts can be used to connect the first type of through hole 2121 of the tower leg connecting plate 21 to the inherent bolt hole where the inherent bolts have been removed. At this time, the retained inherent nuts are inserted into the second type of through hole 2122 of the tower leg connecting plate 21. Two tower leg clamps 22 are symmetrically clamped on both sides of the longitudinal connecting plate 213 of the tower leg connecting plate 21, so that the horizontal plate 221 of the clamp is bolted to the horizontal connecting plate 211 and the longitudinal plate 222 of the clamp is bolted to the longitudinal connecting plate 213. A lifting pad 23 is connected below the clamp rib plate 223, so that the lower surface of the lifting pad 23 is in contact with the top surface of the jack 31. Loosen the nuts of the anchor bolts 14 between the tower leg plate 12 and the foundation 13, and control the two jacks 31 to lift the lifting pad 23, thereby driving the tower leg lifting unit 2, tower leg 11 and tower leg plate 12 to lift synchronously; When the tower foot plate 12 is raised to the preset height, two supporting components 4 are placed between the tower foot plate 12 and the foundation 13, and adjacent supporting components 4 are bolted together by the butt plate 42. At this time, the U-shaped groove 41 of the supporting component 4 is sleeved on the outside of the anchor bolt 14. Control the jack 31 to slowly release pressure, so that the tower leg plate 12 is placed on the support component 4, tighten the nuts of the anchor bolts 14, and disconnect the tower leg lifting unit 2 from the tower leg 11 to complete the correction and straightening of the transmission tower 1.

[0078] In practical implementation, when replacing bolts and installing tower leg connecting plate 21, please refer to the attached document. Figure 11 Alternatively, for the nut removal scheme of option 12, the connection between tower leg 11 and tower base plate 12 typically has 18 inherent bolts and nuts. Remove 9 of these inherent bolts and nuts, leaving the remaining 9. Place the vertical connecting plate 212 of the tower leg connecting plate 21 against the connection surface between the tower leg 11 and tower base plate 12, allowing the remaining 9 inherent nuts to pass through the second type of through hole 2122 of the vertical connecting plate 212. Use 8.8 grade high-strength bolts to connect the first type of through hole 2121 of the vertical connecting plate 212 to the 9 inherent bolt holes after the removal of the inherent bolts, tightening them uniformly to the preset torque value, and installing double caps to ensure a stable connection.

[0079] When assembling the tower leg clamp 22 and the lifting pad 23, the clamping longitudinal plates 222 of the two tower leg clamps 22 can be symmetrically clamped on both sides of the longitudinal connecting plate 213 of the tower leg connecting plate 21, so that the connecting holes of the clamping transverse plate 221 and the transverse connecting plate 211 are aligned, and the connecting holes of the clamping longitudinal plate 222 and the longitudinal connecting plate 213 are aligned, and then fastened together with bolts; the lifting pad 23 is connected to the bottom of the clamping rib plate 223 of the two tower leg clamps 22 by bolts, ensuring that the upper surface of the lifting pad 23 is completely in contact with the bottom surface of the clamping rib plate 223, and the lower surface is in contact with the top surface of the jack 31.

[0080] When lifting the tower leg 11, loosen the nuts of the anchor bolts 14 between the tower foot plate 12 and the foundation 13 by 2-3cm, but do not unscrew them completely; check the tightness of the connections of each part, and after confirming that the lifting conditions are met, control the two jacks 31 to lift the lifting pad 23 synchronously, which will drive the tower leg lifting unit 2, the tower leg 11 and the tower foot plate 12 to lift synchronously; during the lifting process, measure the distance between the tower foot plate 12 and the foundation 13, and at the same time adjust and control the tension of the guy wire to counteract the horizontal force generated by the tilt of the tower 1 and assist the lifting of the lowest leg.

[0081] When the support component 4 is installed, when the tower foot plate 12 is raised to the preset height, the appropriate support component 4 is selected according to the spacing, and the support component 4 is placed between the tower foot plate 12 and the foundation 13 from the side, so that the anchor bolts 14 are sleeved on the outside of the U-shaped groove 41 of the support component 4; the adjacent support components 4 are bolted and fixed through the mating plate 42 to form an integral support structure.

[0082] During system dismantling, the jack 31 can be controlled to slowly depressurize, allowing the tower leg plate 12 to be smoothly placed on the support component 4; tighten the nuts of the anchor bolts 14 to ensure that the tower leg plate 12 is firmly connected to the support component 4 and the foundation 13; in the reverse order of installation, disconnect the tower leg lifting unit 2 from the tower leg 11 in sequence, and remove the lifting pad 23, tower leg clamp 22, tower leg connecting plate 21, jack 31 and other components to complete the correction and adjustment of the transmission tower 1.

[0083] The construction process of this invention is standardized and regulated, with strong on-site operability, which can significantly shorten the construction period of single-tower correction; there is no need to rent large cranes, and the cost of correction per operation is significantly reduced; the correction accuracy is high, which can ensure that the transmission tower 1 reaches the preset level state; the components are reusable and adaptable to the need for multiple corrections in mining subsidence areas; the construction process does not require long-term power outages and can be carried out with power on, reducing the impact on the normal power supply of transmission lines.

[0084] Furthermore, sleepers 52 are laid on both sides of the foundation 13 corresponding to the tower leg 11 of the transmission tower 1 to be corrected, and pads 51 are placed on the sleepers 52. The two pads 51 are connected and fixed by the connecting beam 53. Install the support plate 32 on the base plate 51 and fix it with bolts. Place the jack 31 in the slot of the support plate 32. Adjust the working height of the jack 31 by stacking support plates 32 of different heights.

[0085] In specific implementation, when installing the anti-overturning unit 5, the ground sand can be compacted and leveled on both sides of the foundation 13 corresponding to the tower leg 11 of the transmission tower 1 to be corrected; according to the size of the pad 51 and the stress requirements, at least two sets of sleepers 52 are laid to ensure that the sleepers 52 are evenly distributed and the load is balanced; the pad 51 is placed on the sleepers 52, and the position of the pad 51 is adjusted so that the two pads 51 are symmetrically distributed on both sides of the foundation 13; the connecting beam 53 is passed through the rectangular groove of the pad 51, and the two pads 51 are connected and fixed from both sides of the foundation 13, and tightened with bolts to form a stable anti-overturning foundation.

[0086] When adjusting the height of jack 31, a support platform 32 can be installed on the pad 51, aligning the through hole at the bottom of the support platform 32 with the bolt hole of the pad 51, and then fixed with bolts. Depending on the lifting height requirement, support platforms 32 of different heights can be stacked (e.g., 400mm and 180mm height support platforms 32) to adjust the working height of jack 31. Place jack 31 in the slot of support platform 32 to ensure that jack 31 is placed stably and will not shift laterally. Furthermore, a protective shell 33 can be installed on the outside of jack 31. The protective shell 33 is fitted onto the outside of the bottom of jack 31 to fix jack 31. The protective shell 33 can be fixedly connected to support platform 32 or pad 51 to prevent jack 31 from deviating, tipping over, or being damaged by external impact during the lifting process.

[0087] The installation of anti-overturning unit 5 makes the construction process more stable and safe, and can avoid the risk of system overturning caused by uneven ground or external forces; the stacking and adjustment of the height of the pier 32 is flexible and convenient, which can improve the control accuracy of the lifting height and ensure the quality of correction.

[0088] Example 3: Taking the correction of a certain transmission tower 1 as an example, before officially starting the tilt correction work, the design and construction unit should fully consider the actual working conditions of the tilt of the transmission tower 1, and set up a "one base, one policy" plan for temporary reinforcement measures such as temporary guy wires and hand-operated hoists for the transmission tower 1 to be corrected. This plan includes, but is not limited to, the type of guy wire, the number of guy wires, the orientation of the guy wires, the angle to the ground, the location of the hanging point, the reinforcement of the tower body at the hanging point, the design of guy wire tension, the pre-tension force, the initial tensile stress, the pull-out force of the ground anchor, the burial depth, and other requirements to ensure that the overall structure of the transmission tower 1 is stable and compact during the tilt correction process.

[0089] (1) Installation of the correction and alignment system 1) Compact the sand around the foundation 13, lay several sleepers 52 on both sides of the foundation 13, and then lay steel plates (pads 51) on the sleepers 52 for the installation and fixing of the foundation 32. The steel plates have waist-shaped grooves in the center for bolting to the foundation 32, and waist-shaped grooves on both sides for adjusting the position of the channel steel (connecting beam 53) to fix it to the foundation 13, thus preventing overturning.

[0090] 2) Clean the tower leg 11 and tower base plate 12 in advance, and remove the anti-theft caps from the corresponding bolts on the tower base plate 12. Remove a total of 9 inherent nuts connecting the tower base plate 12 to one side of the main body of the tower leg 11. After removing the inherent nuts, it is strictly forbidden to pull out the inherent bolts. The inherent bolts will remain inside the tower material. Insert the vertical connecting plate 212 of the tower leg connecting plate 21 into the 9 inherent bolts from which the inherent nuts have been removed. Replace the 9 inherent bolts one by one. For each inherent bolt removed, immediately install a pre-prepared 8.8 grade high-strength bolt. After all 9 inherent bolts have been replaced, tighten them uniformly to meet the torque requirements, and install double caps. Then remove a total of 9 inherent nuts connecting the tower base plate 12 to the other side of the main body of the tower leg 11, and install another tower leg connecting plate 21. The installation method is the same as described above.

[0091] 3) The general-purpose correction system is equipped with a set of support platforms 32 at each end. The overall height of the jack 31 is adjusted by stacking support platforms 32 of different heights of 400mm and 180mm. The upper and lower adjacent support platforms 32 are connected by 6 bolts.

[0092] (2) Tower leg lifting The transmission tower 1 is leveled using standardized support components 4 of different heights. First, loosen the anchor nuts of the anchor bolts 14 on the tower foot plate 12 by 2-3 cm, ensuring the nuts are not completely removed. After checking that all connections are secure enough to meet the lifting conditions, control two jacks 31 to lift the tower leg lifting unit 2 until it is under load and then stop. Re-check the stability and the normal operation of the jack 31 system. The jacks 31, in conjunction with the tower leg lifting unit 2, lift the tower foot plate 12. The two jacks 31 can operate simultaneously, maintaining synchronization, and the distance between the tower foot plate 12 and the foundation 13 is measured. During the lifting process, the tension of the control wires is adjusted in a timely manner to counteract the horizontal force generated by the tilt of the transmission tower 1, thus assisting in the lifting of the lowest tower leg 11.

[0093] (3) Tower leveling After gradually lifting the tower foot plate 12 to the required height, use the supporting components 4 to lift it from the side of the foundation 13 (e.g., Figure 2As shown, insert the shims one by one in a crisscross pattern. After completion, use jack 31 to lower the tower leg plate 12 and use the anchor nuts of anchor bolt 14 to fix the tower leg plate 12. During the correction process, set up a surveyor at the center of the tower to measure and correct the actual tilt value until it reaches the preset value. After the correction is completed, remove the tower leg lifting unit 2, lifting power unit 3 and anti-overturning unit 5, and reinstall the inherent bolts and nuts in the order of replacing the high-strength bolts.

[0094] Compared to traditional crane-based alignment methods, this invention reduces the alignment period for a single transmission tower from 5 days to 2 days, increasing alignment efficiency by approximately 60%. It also reduces the need for one 260T crane and one 25T auxiliary crane, saving 15,000 yuan per day and a total of 75,000 yuan. The cost per alignment is reduced by 80%. Therefore, the universal system and method for transmission tower alignment proposed in this invention offers greater on-site operability and significantly improved alignment efficiency. Furthermore, the reusable device is economical and can meet the needs of multiple alignment operations.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the scope of the claims of the present invention.
