Description

Technical Field

[0001] This invention relates to a guiding and docking device and docking method for the erection of power transmission towers, belonging to the field of tower erection technology. Background Technology

[0002] Tower erection is a crucial stage in power grid construction, characterized by its large scale, high technical difficulty, and numerous technical aspects. Current methods using mobile cranes for tower erection require multiple workers to operate from below the suspended tower materials. Furthermore, a malfunction of the mobile crane can easily threaten the safety of construction workers and cause economic losses.

[0003] To avoid safety accidents during tower assembly construction caused by mobile crane malfunctions, improve the safety of tower assembly construction, and reduce safety risks, a segmented complete tower assembly construction technology and its docking method using mobile cranes with quick-disassembly and docking guide devices is adopted in plains, hilly areas, and other regions suitable for mobile cranes. The application of quick-disassembly and docking guide devices in this construction method reduces the number of hoisting operations required for segmented tower assembly, thereby reducing safety hazards during tower material hoisting and assembly.

[0004] However, the current guidance and docking devices still have the following problems: First, existing guiding and docking devices only target the docking of the main tower sections, neglecting the equally important docking of the diagonal braces. This results in incomplete tower assembly by connecting sections, requiring construction workers to install the diagonal braces at height, which is time-consuming and labor-intensive, and the risks of construction workers working at height still exist.

[0005] Secondly, common guide docking methods often rely on the simultaneous insertion of the four corners of the tower section, which is highly susceptible to interference due to processing errors, hoisting deformation, or positioning deviations. During construction, single main members often become stuck, preventing the entire tower section from descending smoothly. This necessitates repeated adjustments to the hoisting position, affecting the work progress and potentially damaging the guide device or the tower material itself if forced docking is attempted.

[0006] In addition, existing guiding devices only have guiding functions. After being guided into place, they cannot ensure that the tower legs will not shift before connection, which leads to difficulties in the connection process.

[0007] Furthermore, devices added to fulfill the guidance function often require welding or drilling into the main tower leg material, compromising the integrity of the original components and potentially creating stress concentration points that affect the long-term safety and durability of the tower. Although some detachable guidance solutions exist, their structures are complex and inconvenient to assemble and disassemble. Summary of the Invention

[0008] The purpose of this invention is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0009] The technical solution provided by this invention is as follows: A guiding and docking device for the erection of power transmission towers, each guiding and docking device including an inner guide component, an outer guide component, and a diagonal bracing guide connector. The inner guide component includes an inner connecting plate and an inwardly bent inner inclined guide plate. The inner connecting plate is used to connect with the tower leg of the tower section. The inwardly bent guide plate is located above the inner connecting plate and bent inward. The outer guide component includes an outer connecting plate and an outwardly bent outer inclined guide plate. The outer connecting plate is used to connect with the tower leg of the tower section. The outwardly bent guide plate is located above the outer connecting plate and bent outward. When the inner guide component... When the outer guide plate and the inner and outer sides of the tower leg are respectively fixed, the inner connecting plate and the outer connecting plate are respectively attached and fixed to the inner and outer sides of the tower leg, forming a positioning groove between them; the inner inclined guide plate and the outer inclined guide plate extend upward from the top of the positioning groove and inclined to the inner and outer sides respectively, forming a funnel-shaped wedge guide groove together; the inclined brace guide connector includes an inclined brace connecting plate and an inclined brace guide plate. The inclined brace connecting plate is used to connect with the tower leg of the tower segment. The inclined brace guide plate is bent inward or outward relative to the inclined brace connecting plate to guide the inclined brace to be aligned and installed to the corresponding position of the tower leg.

[0010] The technical solution provided by this invention has the following advantages compared with the prior art: 1. This invention achieves simultaneous guidance and connection of the main tower section (tower leg) and diagonal bracing by using the inner guide component, outer guide component and diagonal bracing guide connector. It completes the full assembly of the tower section in one go, avoiding the tedious work and safety risks of subsequent high-altitude manual installation of diagonal bracing, and improving construction efficiency and safety.

[0011] 2. The funnel-shaped wedge-shaped guide groove, formed by the inner and outer inclined guide plates, provides ample space for initial insertion, automatically corrects hoisting deviations, and smoothly guides the tower leg to be connected to the positioning groove. The positioning groove is formed by the inner and outer connecting plates closely adhering to both sides of the already erected tower leg. Its width matches the wall thickness of the tower leg, enabling tight constraint on both the inner and outer sides of the tower leg after it slides in. This solves the problem of tower leg movement before connection, allowing for precise docking of tower sections and legs, and improving the accuracy and reliability of tower erection construction.

[0012] 3. The installation holes of the guiding docking device of the present invention are completely consistent with the holes of the cladding and connecting plate on the original tower leg, eliminating the need for additional welding or drilling on the main tower leg material, thus protecting the integrity and mechanical properties of the original components and avoiding stress concentration caused by construction damage.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] Furthermore, the diagonal brace guide connector also includes a limiting block, which is fixed to the diagonal brace connecting plate to limit the installation position of the diagonal brace.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by setting a limit block, the falling stroke and final positioning position of the diagonal brace can be physically limited, preventing over-positioning or positional deviation during the installation of the diagonal brace.

[0016] Furthermore, the inner connecting plate is an L-shaped angle iron, the L-shaped angle iron is provided with several inner bolt holes, and the inner inclined guide plate is two triangular plates connected to the end of the L-shaped angle iron, the two triangular plates are respectively set at an obtuse angle with their respective L-shaped angle iron mounting side plates.

[0017] The beneficial effects of adopting the above-mentioned further solution are that using L-shaped angle iron as the inner connecting plate results in a stable structure and easy fit with the inner side of the tower leg angle steel; the inner inclined guide plate is in the form of two triangular plates and is connected to the angle iron side plate at an obtuse angle, together forming the inner part of the wedge-shaped guide groove with good guidance, ensuring the smoothness of the guidance process.

[0018] Furthermore, the outer connecting plate is a straight plate with several outer bolt holes. When the inner guide and the outer guide are fixed on the inner and outer sides of the tower leg, respectively, the inner bolt holes correspond to and are connected to the outer bolt holes.

[0019] The advantages of adopting the above-mentioned further solution are that the external connecting plate adopts a simple one-piece structure, which is easy to install; the corresponding and continuous inner and outer bolt holes allow the connecting bolts to pass through the outer bolt holes, the tower leg reserved holes, and the inner bolt holes in sequence, realizing a firm connection between the erected tower legs, the tower legs to be connected, and the inner and outer guide components. In addition, the positions of the bolt holes on the L-shaped angle iron and the one-piece plate are compatible with the positions of the bolt holes on the tower legs, eliminating the need for additional drilling in the tower sections and legs to achieve a stable connection with the guide docking device, simplifying the installation steps and improving construction efficiency. At the same time, this also preserves the integrity of the tower leg structure, avoids stress concentration problems caused by drilling, and further enhances the long-term operational safety of the tower.

[0020] Furthermore, the outer connecting plate and the outer inclined guide plate are detachably connected by a pin.

[0021] The beneficial effect of adopting the above-mentioned further solution is that after the tower section is connected, the outward tilting guide plate can be quickly removed, which not only meets the functional requirements of the guidance stage, but also avoids the potential impact of this part of the structure on the long-term operation of the tower.

[0022] Furthermore, each set of the guiding docking device includes one inner guide, two outer guides and two inclined bracing guide connectors, with the two outer guides and one inner guide forming an L-shaped positioning groove.

[0023] Furthermore, the inner inclined guide plate, the outer inclined guide plate, and the inclined brace guide plate are formed by welding or hot bending of the plates.

[0024] Furthermore, the included angle between the inner inclined guide plate and the inner connecting plate, the included angle between the outer inclined guide plate and the outer connecting plate, and the included angle between the inclined brace guide plate and the inclined brace connecting plate are all 145°–149°; the length range of the inner inclined guide plate, the outer inclined guide plate, and the inclined brace guide plate is 150mm–180mm.

[0025] The beneficial effect of adopting the above-mentioned further solution is that the included angle range can provide sufficient guide ramp length to allow for fault tolerance while ensuring guidance efficiency and avoiding problems such as insufficient guidance due to excessive angle or easy collision of structure due to excessive angle; the guide plate length range ensures that there is sufficient guide contact surface so that the tower leg and diagonal brace can slide into place smoothly and steadily.

[0026] This invention also discloses a guiding and docking method for the erection of transmission towers, employing the guiding and docking device described above, for docking and installing the tower section to be connected onto an existing tower section. The existing tower section includes multiple erected tower legs, and the tower section to be connected includes multiple tower legs to be installed and diagonal braces, comprising: S1: On each of the erected tower legs, the inner connecting plate of the inner guide member is fixed to the inner side of the erected tower leg, and the outer connecting plate of the outer guide member is fixed to the outer side of the erected tower leg, so that the inner inclined guide plate and the outer inclined guide plate form the wedge-shaped guide groove, and a positioning groove is formed between the inner connecting plate and the outer connecting plate; among the guide docking devices installed on each of the erected tower legs, at least two have different installation heights; S2: Install diagonal bracing guide connectors on each of the aforementioned erected tower legs; S3: Hoist the tower section to be connected, and use the wedge-shaped guide grooves at different heights on the different erected tower legs to connect the multiple tower legs to be connected in order from high to low. During the docking process, the end of the tower leg to be installed slides into the wedge-shaped guide groove and is positioned in the positioning groove, while the lower end of the diagonal brace is aligned and installed to the corresponding position of the already erected tower leg under the guidance of the diagonal brace guide plate. S4: Pass the connector through the outer bolt hole, the middle bolt hole opened on the tower leg to be installed, and the inner bolt hole in sequence to complete the connection between the tower section to be installed and the tower section already erected.

[0027] The technical solution provided by this invention has the following advantages compared with the prior art: First, during docking, the wedge-shaped guide groove guides the end of the tower leg to be docked from high to low and from wide to narrow into the positioning groove, ensuring that the tower leg to be docked accurately and quickly onto the existing tower leg. The wedge-shaped guide groove allows the tower leg to be docked smoothly into the positioning groove along its inclined surface, avoiding the tedious steps of manually adjusting the position of the tower leg required in traditional docking methods, greatly saving manpower and time costs. Second, when the tower leg to be docked slides into the positioning groove, the inner connecting plate and the outer connecting plate are located on the inner and outer sides of the tower leg to be docked, respectively. The width of the positioning groove matches the wall thickness of the existing tower leg, which can simultaneously achieve tight positioning on both the inner and outer sides of the tower leg after it slides in, avoiding docking deviation and ensuring the reliability and stability of the tower segment connection.

[0028] Furthermore, at least two of the guiding docking devices installed on each of the existing tower legs have different installation heights, resulting in different docking heights for the tower legs. This creates a tower leg drop positioning sequence from high to low, allowing multiple tower legs to be positioned sequentially from high to low during docking. Based on the sequential positioning principle, compared to the traditional segmented tower assembly mode where all four tower legs are positioned simultaneously, the application of the sequential positioning principle avoids over-definition problems caused by simultaneous insertion of tower legs, reduces assembly interference, lowers the precision requirements for guide component processing, reduces the difficulty of segmented tower assembly docking, shortens tower assembly construction time, and improves tower assembly efficiency.

[0029] Furthermore, by installing diagonal brace guide connectors on each erected tower leg, the alignment and installation of the diagonal braces can be further guided. The limiting blocks of the diagonal brace guide connectors ensure the accuracy and stability of the diagonal braces during installation, avoiding installation difficulties or safety hazards caused by diagonal brace position deviations.

[0030] Furthermore, after docking is completed, the pin of the outer guide is pulled out, and the outward tilting guide plate is removed from the outer connecting plate.

[0031] The beneficial effects of adopting the above-mentioned further solution are that after completing the guiding mission, the outward tilting guide plate can be removed in a timely manner, allowing the tower to quickly return to its standard design shape and eliminating the potential impact of external attachments on structural safety. At the same time, the outward tilting guide plate can also be recycled for the assembly of subsequent tower sections, improving material utilization and reducing overall costs.

[0036] The principles and features of the present invention are described below with reference to examples. The examples are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0037] like Figures 1-9 As shown, a guiding and docking device for the erection of power transmission towers includes an inner guide 1, an outer guide 2, and a diagonal brace guide connector 3. The inner guide 1 includes an inner connecting plate 7 and an inwardly bent inner inclined guide plate 8. The inner connecting plate 7 is used to connect with the tower leg of the tower section, and the inwardly bent guide plate 8 is located above the inner connecting plate 7 and bent inward. The outer guide 2 includes an outer connecting plate 9 and an outwardly bent outer inclined guide plate 10. The outer connecting plate 9 is used to connect with the tower leg of the tower section, and the outwardly bent guide plate 10 is located above the outer connecting plate 9 and bent outward. When the inner guide 1 and the outer guide 2 are respectively fixed to the tower leg... When connecting the inner and outer sides of the tower leg, the inner connecting plate 7 and the outer connecting plate 9 are respectively attached and fixed to the inner and outer sides of the tower leg, forming a positioning groove 18 between them; the inner inclined guide plate 8 and the outer inclined guide plate 10 extend upward from the top of the positioning groove 18 and inclined to the inner and outer sides respectively, forming a trumpet-shaped wedge guide groove 17 to realize the self-guided docking of the tower segment and tower leg; the inclined brace guide connector 3 includes an inclined brace connecting plate 15 and an inclined brace guide plate 16. The inclined brace connecting plate 15 is used to connect with the tower segment and tower leg, and the inclined brace guide plate 16 is bent inward or outward relative to the inclined brace connecting plate 15 to guide the inclined brace 6 to be installed in the corresponding position of the tower leg.

[0038] The bending direction of the diagonal brace guide plate 16 is determined by the final installation position of the diagonal brace 6. If the diagonal brace 6 is installed on the outside of the tower leg, the guiding part of the diagonal brace guide plate 16 bends inward towards the tower section; if the diagonal brace 6 is installed on the inside of the tower leg, the guiding part of the diagonal brace guide plate 16 bends outward towards the tower section. The diagonal brace guide connector 3 also includes a limiting block 14, which is fixed on the diagonal brace connecting plate 15 to limit the installation position of the diagonal brace 6. The diagonal brace connecting plate 15 is provided with bolt holes for connection to the tower leg and bolt holes for connection to the diagonal brace 6. First, the diagonal brace guide connector 3 is fixed to the erected tower leg 4 through the bolt holes on the diagonal brace connecting plate 15; after the diagonal brace 6 is guided into position, the diagonal brace 6 is then firmly connected to the diagonal brace connecting plate 15 with bolts.

[0039] The inner connecting plate 7 is an L-shaped angle iron with several inner bolt holes. The inner inclined guide plate 8 consists of two triangular plates connected to the end of the L-shaped angle iron. The two triangular plates are respectively set at an obtuse angle to their respective L-shaped angle iron mounting side plates.

[0040] The outer connecting plate 9 is a straight plate, and the straight plate is also provided with several outer bolt holes. When the inner guide 1 and the outer guide 2 are fixed on the inner and outer sides of the tower leg of the tower section respectively, the inner bolt holes correspond to and are connected with the outer bolt holes.

[0041] The outer connecting plate 9 and the outer inclined guide plate 10 are detachably connected by a pin 11. Specifically, the outer connecting plate 9 has a groove at one end, and the outer inclined guide plate 10 has a boss at one end corresponding to the outer connecting plate 9 that can mate with the groove. Through holes are correspondingly provided on both sides of the groove of the outer connecting plate 9 and on the boss of the outer inclined guide plate 10. During assembly, the boss is inserted into the groove, the through holes are aligned, and then the pin 11 is inserted into the through holes, thereby achieving a reliable connection between the outer inclined guide plate 10 and the outer connecting plate 9.

[0042] To further improve structural strength, a pressure plate 13 is also provided on one side of the boss of the outer connecting plate 9. The pressure plate 13 is used to bear the main collisions and pressures during the docking process of the tower legs, preventing the pin 11 from being directly subjected to force and deformed or damaged, thereby significantly improving the overall safety and working stability of the guiding docking device.

[0043] Each set of the guiding and docking device includes one inner guide 1, two outer guides 2, and two diagonal bracing guide connectors 3. The two outer guides 2 and one inner guide 1 together form an L-shaped positioning groove 18. The inner connecting plate 7 of the inner guide 1 is an L-shaped angle iron. The two outer guides 2 are respectively vertically arranged on two adjacent outer sides of the L-shaped angle iron and cooperate with the inner guide 1. Specifically, one outer guide 2 is arranged corresponding to one outer plate of the L-shaped angle iron, and the other outer guide 2 is arranged corresponding to the other adjacent outer plate of the L-shaped angle iron. Thus, one inner guide 1 and two outer guides 2 together enclose and form an L-shaped positioning groove 18 that matches the cross-sectional shape of the tower leg angle steel.

[0044] The inner inclined guide plate 8, the outer inclined guide plate 10, and the inclined brace guide plate 16 are formed by welding or hot bending of the plates.

[0045] The included angles between the inner inclined guide plate 8 and the inner connecting plate 7, the included angles between the outer inclined guide plate 10 and the outer connecting plate 9, and the included angles between the inclined brace guide plate 16 and the inclined brace connecting plate 15 are all 145°–149°. The lengths of the inner inclined guide plate 8, the outer inclined guide plate 10, and the inclined brace guide plate 16 range from 150mm to 180mm.

[0046] A guiding and docking method for the erection of power transmission towers employs the guiding and docking device described above, used to dock and install the tower section to be connected onto the already erected tower section 12. The already erected tower section 12 includes multiple erected tower legs 4, and the tower section to be connected includes multiple tower legs to be installed 5 and diagonal braces 6.

[0047] In this embodiment, four sets of the aforementioned guiding and docking devices are used to dock and install the tower section to be connected onto the erected tower section 12. The erected tower section 12 includes four erected tower legs 4, and the tower section to be connected includes four tower legs to be installed and two diagonal braces 6. The process includes the following steps: S1: Install the guide docking device on each of the erected tower legs 4: vertically fix the inner connecting plate 7 of the inner guide 1 to the inner side of the erected tower leg 4, and vertically fix the outer connecting plate 9 of the outer guide 2 to the outer side of the erected tower leg 4, so that the inner inclined guide plate 8 and the outer inclined guide plate 10 form a wedge-shaped guide groove 17, and a positioning groove 18 is formed between the inner connecting plate 7 and the outer connecting plate 9; among the guide docking devices installed on each of the erected tower legs 4, at least two have different installation heights.

[0048] More specifically, when the inner guide 1 and the outer guide 2 are installed on the erected tower leg 4 through the inner connecting plate 7 and the outer connecting plate 9, the inner connecting plate 7 and the outer connecting plate 9 are respectively attached and fixed to the inner and outer sides of the erected tower leg 4. The inner connecting plate 7 and the outer connecting plate 9 are parallel to each other and spaced apart, thereby forming a positioning groove 18 between them with a width matching the wall thickness of the erected tower leg 4, which is used to limit the end of the tower leg to be inserted later. The inner inclined guide plate 8 and the outer inclined guide plate 10 extend upward from the top of the positioning groove 18 and inclined to the inner and outer sides respectively, together forming the trumpet-shaped wedge-shaped guide groove 17 for guiding the docking of the tower legs to be connected.

[0049] During docking, the wedge-shaped guide groove 17 guides the end of the tower leg to be docked from high to low and from wide to narrow into the positioning groove 18, ensuring that the tower leg to be docked accurately and quickly onto the existing tower leg 4. The wedge-shaped guide groove 17 allows the tower leg to be docked to slide smoothly into the positioning groove 18 along its inclined surface, avoiding the tedious steps of manually adjusting the position of the tower leg required in traditional docking methods, greatly saving manpower and time costs. When the tower leg to be docked slides into the positioning groove 18, the inner connecting plate 7 and the outer connecting plate 9 are located on the inner and outer sides of the tower leg to be docked, respectively. The width of the positioning groove 18 matches the wall thickness of the existing tower leg 4, which can simultaneously achieve tight positioning on the inner and outer sides of the tower leg to be docked after it slides in, avoiding docking deviation and ensuring the reliability and stability of the tower segment connection. In addition, by installing the diagonal brace guide connector 3 on each existing tower leg 4, the alignment and installation of the diagonal brace 6 can be further guided. The limiting block 14 of the diagonal brace guide connector 3 ensures the accuracy and stability of the diagonal brace 6 during installation, avoiding installation difficulties or safety hazards caused by the positional deviation of the diagonal brace 6.

[0050] In the four sets of guiding and docking devices, the vertical distance d from the root of the inner inclined guide plate 8 and / or the outer inclined guide plate 10 to the topmost bolt hole is different in each set. Specifically, as... Figure 1 As shown, in one set of guiding and docking devices, the value of d1 is 180mm; in another set, the value of d2 is 110mm; and in the remaining two sets, the values ​​of d3 and d4 are both 40mm. The inner guide component 1 and outer guide component 2 in the four docking guiding devices have different docking heights. These different guide heights form a tower leg drop positioning sequence from high to low. During docking, the four tower legs are positioned sequentially from high to low. The four tower legs are docked based on the sequential positioning principle. Compared to the traditional segmented tower assembly mode where all four tower legs are positioned simultaneously, the application of the sequential positioning principle avoids the over-definition problem caused by simultaneous insertion of the four corners of the tower legs, reduces assembly interference, lowers the precision requirements for guide component processing, reduces the difficulty of segmented tower assembly docking, shortens tower assembly construction time, and improves tower assembly operation efficiency.

[0051] S2: The diagonal brace guide connector 3 is installed on each of the erected tower legs 4. One side of the diagonal brace connecting plate 15 of the diagonal brace guide connector 3 is connected to the erected tower leg 4, and the other end of the diagonal brace connecting plate 15 extends away from the erected tower leg 4. A bent diagonal brace guide plate 16 is provided at the upper end of the diagonal brace connecting plate 15, and a limiting block 14 is welded below the diagonal brace guide plate 16. In this embodiment, a first diagonal brace guide connector and a second diagonal brace guide connector are installed on both sides of each of the erected tower legs 4. The diagonal brace guide plate 16 of the first diagonal brace guide connector is bent inward, and the diagonal brace guide plate 16 of the second diagonal brace guide connector is bent outward. The diagonal braces 6 on both sides are aligned and installed at the corresponding positions of the erected tower legs 4.

[0052] S3: Hoist the tower section to be connected, and use the wedge-shaped guide grooves 17 at different heights on the different erected tower legs 4 to connect the multiple tower legs 5 to be connected in order from high to low. During the docking process, the end of the tower leg 5 to be installed slides into the wedge-shaped guide groove 17 and is positioned in the positioning groove 18. At the same time, the lower end of the diagonal brace 6 is aligned and installed to the corresponding position of the already erected tower leg 4 under the guidance of the diagonal brace guide plate 16. S4: Pass the connector through the outer bolt hole, the middle bolt hole and the inner bolt hole of the tower leg 5 to be installed in sequence to complete the connection between the tower section to be installed and the tower section 12 already erected.

[0053] After docking is completed, pull out the pin 11 of the outer guide 2 and remove the outward tilting guide plate 10 from the outer connecting plate 9.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
