Description

Technical Field

[0001] This invention relates to the field of power transmission line tower erection equipment technology, and in particular to a helicopter tower erection guidance and positioning system and tower erection method. Background Technology

[0002] Tower erection is a crucial part of power transmission line construction. Traditional tower erection methods include pole erection (such as suspended pole erection and ground-mounted pole erection), but pole erection has problems such as high safety risks, large moving weight, numerous auxiliary devices, and low production efficiency. With the development of technology, helicopter hoisting tower erection has emerged. Compared with traditional tower erection methods, helicopter hoisting tower erection has advantages such as high construction efficiency, no geographical constraints, good environmental benefits, and labor saving.

[0003] While using helicopters for tower assembly has the aforementioned advantages, it places high demands on the weight of tower segments, joint types, and joint locations. The biggest challenge lies in ensuring reliable, accurate, automatic, and rapid (avoiding prolonged hovering) docking of tower segments in the air, minimizing human intervention. Therefore, to reduce the impact of helicopter pilots' skills on the tower assembly process and improve safety and efficiency, it is crucial to establish a guiding and positioning device during the tower segment docking process.

[0004] However, existing guide positioning devices have the following drawbacks: most common guide positioning devices are integrated structures with a bent and tilted head, which guides the docking of two tower sections. However, due to factors such as the thickness and deformation of the tower sections and connecting tower materials, it is difficult to dock the two tower sections with the connecting tower materials pre-installed, which can easily lead to structural interference. However, docking the two tower sections first and then installing the connecting tower materials will increase the difficulty of installing the connecting tower materials. In addition, the structure of the conductor positioning device is relatively fixed and it is difficult to adjust it to meet the tower assembly requirements of tower sections with different tower material specifications.

[0005] Therefore, based on years of experience and practice in related industries, the inventor proposes a helicopter tower assembly guidance and positioning system and tower assembly method to overcome the shortcomings of existing technologies. Summary of the Invention

[0014] An adjustment port is provided on the extension, and a connecting arm is slidably nested on the support assembly. The end of the connecting arm can be movably and adjustably connected to the adjustment port in a third direction.

[0015] The positioning component also includes a positioning plate, which is arranged at intervals with the positioning seat, and the positioning plate is detachably connected to and fixed the main material head of the fixed tower section and the support component.

[0016] In a preferred embodiment of the present invention, the support assembly and the guide are located inside the head of the main material of the fixed tower section, and the connecting tower material is located outside the head of the main material of the fixed tower section. The lower end of the guide and the upper part of the connecting tower material are spaced apart. The lower end of the guide and the upper inner side of the connecting tower material are matched and adapted.

[0017] In a preferred embodiment of the present invention, the helicopter tower guidance and positioning system further includes a restraint device detachably connected to the mounting tower section. The restraint device is used to limit the relative movement between the main members' feet of the mounting tower section.

[0022] As described above, the helicopter tower assembly guidance and positioning system and tower assembly method of the present invention have the following beneficial effects:

[0023] 1. The helicopter tower guiding and positioning system of the present invention has an adjustable docking device for the guide component, which can support and fix the connecting tower material. The guide component can effectively adapt and connect with the pre-installed connecting tower material by adjusting the position of its lower end, forming a smooth guiding transition for the installation tower section. This can reduce structural interference between the installation tower section and the connecting tower material, and allow for stable and smooth docking between the installation tower section and the fixed tower section.

[0024] 2. In the docking device of the helicopter tower guiding and positioning system of the present invention, the support component and the positioning component are multi-part adjustable structures. They can be adapted to the original holes on the tower material of the fixed tower section and can adapt to the tower material of different specifications. The structure is stable, the connection is firm, and it is not easy to loosen or fall off. At the same time, the support component and the positioning component of the docking device can be initially connected, which is convenient for carrying and installation, reduces the probability of falling off during tower climbing and installation, and has high safety.

[0025] 3. The helicopter tower guiding and positioning system of the present invention is also equipped with a constraint device. The constraint device can make a hard connection between the tower materials of the installation tower section, constrain the distance between the tower materials of the installation tower section, enhance the structural stability of the tower materials of the installation tower section, reduce deformation and sway, and enable the installation tower section and the fixed tower section to make more stable contact and cooperation, reduce docking difficulty, and improve construction efficiency.

[0026] 4. The tower erection method of the present invention utilizes an improved helicopter tower erection guidance and positioning system to optimize each operation node that is prone to safety risks, reduce the probability of accidents, and achieve efficient and safe helicopter hoisting tower erection operations through orderly operation.

[0038] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] like Figure 1 As shown, in existing tower assembly guidance and positioning systems, the guide portion formed by bending and tilting on the traditional guide plate 1 is an integral fixed structure. When two tower sections are docked, due to various factors such as interference from the thickness of the main material of the tower sections and deformation of the main material of the tower sections, the traditional guide plate 1 is difficult to guide the two tower sections to dock smoothly and stably when the connecting tower materials are pre-installed on the tower sections. If the two tower sections are docked first and then the connecting tower materials are installed, collisions between the main materials of the tower sections are likely to occur during docking. Furthermore, the instability of the docking of the main materials of the two tower sections and the large docking error will increase the difficulty of installing the connecting tower materials. In the process of installing the connecting tower materials, there is even a safety risk of collapse due to misalignment of the main materials of the two tower sections. In addition, in order to improve the installation adaptability, the guide plate 1 and the hanging rope component 2 are usually in the form of separate parts, and are only connected and locked to each other at the head of the main material of the fixed tower section 3. However, during the disassembly and assembly of the guide plate 1 and the hanging rope component 2, especially when making or breaking the connection between the guide plate 1 and the hanging rope component 2, the guide plate 1 and the hanging rope component 2 are very easy to detach and fall apart, which can easily affect the construction safety and construction efficiency.

[0042] like Figures 2 to 8 As shown, the present invention provides a helicopter tower erection guidance and positioning system, which is applicable to the hoisting (especially helicopter hoisting) erection of towers such as upright towers and inward-leaning inclined towers. It includes a docking device 5 for guiding the main material foot of the tower section 4 to be connected to the main material head of the fixed tower section 3 via the connecting tower material 7 during helicopter tower erection; the docking device 5 is adapted to be detachably installed at the main material head of the fixed tower section 3.

[0043] The docking device includes a support component 51, a positioning component 52, and a guide component 53. The support component 51 and the positioning component 52 are respectively disposed on the inner and outer sides of the main body head of the fixed tower section 3. The support component 51 and the positioning component 52 are detachably disposed on the main body head of the fixed tower section 3 and are used to connect the lower part of the connecting tower material 7 to the main body head of the fixed tower section 3. The guide component 53 is movably disposed above the support component 51, and the upper end of the guide component 53 is inclined towards the inner side of the main body head of the fixed tower section 3. The lower end of the guide component 53 matches and adapts to the upper end of the connecting tower material 7 to guide the main body foot of the installation tower section 4 to smoothly connect to the upper part of the connecting tower material 7 along the length direction.

[0044] The guide 53 can be adjusted at its lower end to effectively adapt and connect with the pre-installed connecting tower material 7, forming a smooth guiding transition for the installation tower section 4. This reduces structural interference between the installation tower section 4 and the connecting tower material 7, allowing for a stable and smooth connection between the installation tower section 4 and the fixed tower section 3.

[0045] This invention enables a tower assembly method where the connecting tower material 7 is pre-installed on the fixed tower section 3. Furthermore, the adjustable guide 53 reduces or eliminates structural interference between the connecting tower material 7 and the main body feet of the installation tower section 4 caused by factors such as thickness and deformation. This allows for smooth docking between the main body feet of the installation tower section 4 and the connecting tower material 7. With the assistance of the connecting tower material 7, a stable docking is achieved between the main body feet of the installation tower section 4 and the main body head of the fixed tower section 3. The main body feet of the installation tower section 4 are guided and constrained by the guide 53 and the connecting tower material 7, solving the problems of high docking difficulty due to not pre-installing the connecting tower material 7 and unsmooth docking due to pre-installing the connecting tower material 7 in traditional tower assembly processes. This effectively improves tower assembly efficiency and safety.

[0046] Furthermore, the positions of the support component 51, guide 53, and connecting tower material 7 relative to the head of the main material of the fixed tower section 3 can be adjusted. In one specific embodiment, such as Figures 2 to 4 As shown, the support component 51, guide 53, and connecting tower 7 are located inside the head of the main material of the fixed tower section 3. The upper end of the guide 53 is inclined towards the inner side of the head of the main material of the fixed tower section 3, and the bottom end of the guide 53 is located above the connecting tower 7. The lower end of the guide and the upper end of the connecting tower are matched and adapted. Specifically, the shape of the lower end of the guide 53 is adapted to the shape of the upper end of the connecting tower 7. The guide 53 can be adjusted to align and connect the lower end of the guide 53 and the upper end of the connecting tower 7.

[0047] The connecting tower material 7 is located on the inner side of the main material head of the fixed tower section 3, which can play a better connection and strengthening effect for inward-leaning towers.

[0048] The lower end of the guide 53 is adapted to the upper end of the connecting tower 7. Specifically, when the main material of the fixed tower section 3 and the installation tower section 4 in this invention is an angle steel structure, the connecting tower 7 can also be an angle steel structure. In this case, the lower end of the guide 53 needs to adapt to the shape of the main material foot of the installation tower section 4 and the angle steel structure of the connecting tower 7. When the lower end of the guide 53 and the upper end of the connecting tower 7 are aligned and connected, the guide 53 can guide the main material foot of the installation tower section 4 to slide down stably and then engage with the connecting tower 7.

[0049] The alignment of the lower end of the guide member 53 with the upper end of the connecting tower material 7 means that, in the direction in which the main material foot of the installation tower section 4 slides down along the guide member 53, the upper end of the connecting tower material 7 is flush with or even slightly lower than the lower end of the guide member 53, thereby eliminating structural interference between the upper end of the connecting tower material 7 and the main material foot of the installation tower section 4, allowing the two to be smoothly joined.

[0050] Since the guide 53 and the connecting tower material 7 are both located inside the main material head of the fixed tower section 3, and the fixed tower section 3 has multiple main material heads that are connected to multiple main material feet on the installation tower section 4, the installation tower section 4 as a whole will be guided, constrained and positioned by the combined action of the multiple guide 53 and connecting tower material 7 on the fixed tower section 3. This allows each main material foot of the installation tower section 4 to slide down close to the corresponding guide 53 and connecting tower material 7 and engage with the main material head of the corresponding fixed tower section 3 below. This effectively reduces the probability of misalignment and collapse when the main material feet of the installation tower section 4 are connected to the main material head of the fixed tower section 3, thereby effectively improving the tower assembly efficiency and safety.

[0051] like Figure 3 and Figure 4 As shown, a receiving gap 5111 is adapted to be formed between the support component 51 and the main material head of the fixed tower section 3. The support component 51 is adapted to form a support at the bottom of the receiving gap 5111. The connecting tower material 7 is adapted to be placed in the receiving gap 5111 and connected and fixed to the main material head of the fixed tower section 3.

[0052] The width of the accommodating gap 5111 can be set to be greater than the thickness of the connecting tower material 7. In addition to facilitating the insertion of the connecting tower material 7, it can also accommodate connecting tower materials 7 of different thicknesses. At the same time, the support component 51 is slightly away from the head of the main material of the fixed tower section 3, which can also make the support point of the support component 51 on the guide 53 closer to the middle position of the guide 53, thereby improving the stability of the support for the guide 53 to a certain extent.

[0053] The accommodating gap 5111 formed between the support component 51 and the main head of the fixed tower section 3 can effectively reduce the installation difficulty of the connecting tower material 7. Before the connecting tower material 7 is installed on the main head of the fixed tower section 3, the construction personnel can briefly place the connecting tower material 7 in the accommodating gap 5111 to retrieve common fasteners such as bolts, reducing the probability of the connecting tower material 7 falling off accidentally during the operation and reducing the construction difficulty.

[0054] like Figures 2 to 4 As shown, the main head of the fixed tower section 3, the main foot of the mounting tower section 4, and the connecting tower 7 are all provided with multiple first connecting holes 31 for interconnection. The support component 51 and the positioning component 52 are adapted to be fixed to the main head of the fixed tower section 3 through the first connecting holes 31, and to fix the connecting tower 7 to the main head of the fixed tower section 3. The first connecting holes 31 are the original holes for connecting and fastening between the main head of the fixed tower section 3, the main foot of the mounting tower section 4, and the connecting tower 7. The docking device 5 of the present invention is adapted to be assembled and used with the original holes on the main head of the fixed tower section 3, the main foot of the mounting tower section 4, and the connecting tower 7, without the need to open new holes, which can effectively reduce the complexity of the docking device 5 and improve the installation adaptability of the docking device 5.

[0055] Furthermore, such as Figures 2 to 7 As shown, the support assembly 51 includes a support base 511 and a support platform 512. The support platform 512 is inclined relative to the support base 511 and is mounted on the support base 511. The support base 511 is detachably connected to the main head of the fixed tower section 3. The guide 53 is fitted onto the support platform 512 and is inclined relative to the support base 511 in a first direction (which can be regarded as the direction in which the main foot of the installation tower section 4 slides down). The lower end of the guide 53 is adapted to be close to the extension line direction of the main head of the fixed tower section 3, and the upper end of the guide 53 is adapted to be away from the extension line direction of the main head of the fixed tower section 3. The guide 53 can be adjusted relative to the support platform 512 in the first direction so that the lower end of the guide 53 is close to or away from the extension line direction of the main head of the fixed tower section 3. Since the connecting tower material 7 in this invention is pre-installed on the main head of the fixed tower section 3, the lower end of the guide 53 is also adapted to be close to or away from the upper end of the connecting tower material 7.

[0056] The guide member 53 is disposed on the support platform 512. The support platform 512 is used to provide sufficient support for the guide member 53, especially the lower end of the guide member 53. In this invention, the support range of the support platform 512 in the first direction exceeds 50% of the length of the guide member 53 and is close to the lower end of the guide member 53, which can achieve a higher stability effect, improve the load-bearing capacity of the guide member 53, reduce the probability of the guide member 53 deforming and falling, and thus better cope with the contact impact of the main material foot of the installation tower section 4.

[0057] like Figures 2 to 6 As shown, the support base 511 and the support platform 512 are separate structures. The support base 511 and the support platform 512 are connected along the second direction. Multiple positioning holes 5112 are provided on the support base 511 and the support platform 512 along the second direction. The support base 511 and the support platform 512 are adapted to change their relative positions in the second direction through the positioning holes 5112.

[0058] In this invention, the second direction is the length direction of the main material head of the fixed tower section 3. The support base 511 and the support platform 512 are adapted to be connected by bolts or other common fasteners between different positioning holes 5112 to move closer or further away along the second direction, thereby adapting to the connection and connection between connecting tower materials 7 of different lengths and improving the applicability of the docking device 5.

[0059] Furthermore, such as Figures 2 to 7As shown, the docking device 5 includes a first linkage assembly 54 with adjustable length. The upper end of the guide 53 extends out of the support platform 512. The first linkage assembly 54 is supported between the upper ends of the support assembly 51 and the guide 53, thereby forming a more stable structural support through a triangular structure. The first linkage assembly 54 is used to assist the support platform 512 in forming a higher strength support for the guide 53, so as to further cope with the contact impact of the main material foot of the larger installation tower section 4. At the same time, since the length of the first linkage assembly 54 is adjustable, it can better adapt to the movement and adjustment of the guide 53 on the support platform 512, ensuring the formation of a stable structural support.

[0060] The first linkage assembly 54 includes a first linkage segment 541, a second linkage segment 542, and an adjusting segment 543. The first linkage segment 541 and the second linkage segment 542 are respectively hinged to the upper ends of the support assembly 51 and the guide 53. The two ends of the adjusting segment 543 are respectively coaxially connected to the first linkage segment 541 and the second linkage segment 542 and are length-adjustable (threaded). By controlling the rotation of the adjusting segment 543 relative to the first linkage segment 541 and the second linkage segment 542, the first linkage segment 541 and the second linkage segment 542 can be adapted to move closer to or further away from each other, thereby achieving rapid adjustment and reducing the difficulty and complexity of operation.

[0061] Furthermore, such as Figures 4 to 6 As shown, a first limiter 5121 is provided on the support platform 512 along the first direction. The first limiter 5121 can be adjusted and moved along the first direction and abuts against the first limiter 5121. The first limiter 5121 is used to restrict the guide 53 from sliding down along the first direction. The first limiter 5121 is used to fine-tune the position of the guide 53 in the first direction. It is used to achieve a fixed connection with the holes opened on the support platform 512 and the guide 53. In addition, it can also improve the stability of the guide 53 on the support platform 512 and reduce the probability of the guide 53 becoming loose and slipping due to contact impact from the main material foot of the installation tower section 4.

[0062] In a specific embodiment of the present invention, the first limiter 5121 is a screw, and the movement adjustment in the first direction can be achieved by rotating the screw.

[0063] like Figure 7 As shown, the docking device 5 includes one or more extension members 55. The extension members 55 are sequentially joined end to end along the first direction at the upper end of the guide member 53. The extension members 55 are used to increase the range of the docking device 5 for receiving the main material feet of the installation tower section 4, so that the main material feet of the installation tower section 4 can enter the docking device 5 more easily, thereby improving construction efficiency.

[0064] like Figure 7As shown, the upper end of the guide 53 and / or the extension 55 are provided with a plurality of adjustment holes 551 along the first direction. The length of mutual engagement between the guide 53 and the extension 55 and between adjacent extensions 55 can be changed through the adjustment holes 551. The position of the extension 55 can be changed as needed, thereby improving the structural strength between the extension 55 and the guide 53, or further increasing the range of the main material foot of the receiving and mounting tower section 4 of the docking device 5.

[0065] Furthermore, such as Figures 2 to 7 As shown, the positioning component 52 includes a positioning seat 521, which has an extension 522 and an outward extension 523. The positioning seat 521 is detachably connected to the head of the main material of the fixed tower section 3. Specifically, the positioning seat 521 can be connected to the support component 51 through the first connecting hole 31 of the head of the main material of the fixed tower section 3. The extension 522 extends out of one side of the head of the main material of the fixed tower section 3 and is connected to the support component 51. The extension 522 can be adjusted and moved along the width direction (third direction) of the head of the main material of the fixed tower section 3 to be connected to the support component 51. The positioning seat 521 and the support component 51 can be initially connected through the extension 522. A new connection can be formed independently outside the connection state between the positioning seat 521, the support component 51 and the fixed tower section 3. When making or breaking the connection between the two and the fixed tower section 3, the construction personnel can hold the positioning seat 521 (support component 51) to ensure that the support component 51 (positioning seat 521) will not fall, thereby effectively improving the construction efficiency and the safety of the construction process.

[0066] like Figure 5 and Figure 6 As shown, the extension 522 has an adjustment port 5221, and the support component 51 is connected to the adjustment port 5221. The support component 51 and the positioning seat 521 are movable and adjustable along a third direction through the adjustment port 5221. In this invention, the third direction is perpendicular to the second direction, so that the positioning seat 521 can be movable and adjusted along the width direction of the main material of the fixed tower section 3 to adapt to the connection of the first connection hole 31 on different fixed tower sections 3, thereby improving the adjustable and adaptable installation capability of the docking device 5.

[0067] like Figure 5 and Figure 6 As shown, the adjustment port 5221 is a strip-shaped hole, and the length direction of the adjustment port 5221 is the third direction.

[0068] like Figures 2 to 7As shown, the upper end of the protrusion 523 extends away from the head of the main material of the fixed tower section 3. The protrusion 523 cooperates to guide the foot of the main material of the installation tower section 4 to approach the connecting tower material 7. The protrusion 523 is adapted to play a guiding role. When the installation tower section 4 has a tendency to collapse during the assembly process, the protrusion 523 is adapted to limit the collapse of the installation tower section 4 by blocking it, and guides the foot of the main material of the installation tower section 4 to approach the connecting tower material 7 through the inclined structure, and can guide it to the vicinity of the head of the main material of the fixed tower section 3.

[0069] like Figures 2 to 7 As shown, the extended portion 523 is provided with a guide port 5231, which is used to connect the guide rope. The guide port 5231 is provided with guide wheels 5232 for guiding the guide rope in the direction of approaching and away from the head of the main material of the fixed tower section 3. In the prior art, the upper end of the guide rope is connected to the installation tower section 4, and then falls to the ground through the guide port of the guiding positioning device. Construction workers on the ground can adjust the relative position between the installation tower section 4 and the fixed tower section 3 by pulling the guide rope. However, the guide rope and the guide port are prone to wear. If the guide rope breaks due to wear, it will affect the construction efficiency at best and pose a safety risk at worst. The present invention improves the guide port 5231 by adding guide wheels 5232 at the position where the guide port 5231 and the guide rope come into contact. This can effectively reduce the contact wear between the guide port 5231 and the guide rope, and at the same time greatly improve the smoothness of the guide rope passing through the guide port, thereby improving the construction efficiency and construction safety.

[0070] like Figure 5 and Figure 6 As shown, the positioning seat 521 has a connection port 5211, and the support component 51 is connected to the connection port 5211. The support component 51 and the positioning seat 521 can be adjusted to move along the second direction through the connection port 5211. The positioning seat 521 can be fixed at any position in the second direction within the coverage area of ​​the connection port 5211, so that the lowest point of the outward extension 523 can be flush with the head of the main material of the fixed tower section 3, thereby enabling the outward extension 523 to play a better guiding role. The positioning seat 521 is provided with a second limiter 5212, which can be adjusted to move along the second direction. The second limiter 5212 is used to restrict the positioning seat 521 from sliding down in the second direction. The second limiter 5212 can adjust the position of the positioning seat 521 in the second direction and improve the stability of the positioning seat 521 in the current position, reducing the probability of the positioning seat 521 moving relative to the fixed tower section 3.

[0071] In a specific embodiment of the present invention, the second limiter 5212 is a screw, and the movement adjustment in the second direction can be achieved by rotating the screw.

[0072] In a specific embodiment of the present invention, the number of positioning seats 521 can be set according to the tower material shape of the fixed tower section 3. In the present invention, the tower material of the fixed tower section 3 is angle steel, and the number of positioning seats 521 is two, which can be connected to different sides of the tower material of the fixed tower section 3 respectively.

[0073] like Figure 5 and Figure 6 As shown, a connecting arm 513 is slidably nested on the support component 51. The end of the connecting arm 513 can extend out to one side of the main material head of the fixed tower section 3 and connect to the adjustment port 5221. Since the positioning seat 521 can be adjusted along the second direction, the cooperation between the positioning seat 521 and the connecting arm 513 can help the positioning seat 521 to be effectively fixed at any position in the second direction and strengthen the structural strength. The connecting arm 513 is suitable for being fixed to the support component 51 through the positioning hole 5112. The connecting arm 513 can utilize the original structure on the support component 51 to avoid structural complexity.

[0074] like Figure 5 and Figure 6 As shown, the positioning component 52 also includes a positioning plate 524. The positioning plate 524 and the positioning seat 521 are arranged at intervals, and the positioning plate 524 can be detachably connected and fixed to the main material head of the fixed tower section 3 and the support component 51. The positioning plate 524 and the positioning seat 521 are respectively disposed on the inner and outer sides of the main material head of the fixed tower section 3. The positioning plate 524 is connected and fixed to the support component 51 through the first connecting hole 31 of the main material head of the fixed tower section 3. The connection stability of the positioning seat 521 is improved by direct connection, or the two sides extend out from the two sides of the main material head of the fixed tower section 3 and are connected and fixed to the support component 51. The connection stability of the positioning seat 521 is improved by clamping.

[0075] The docking device of the helicopter tower guiding and positioning system of the present invention features a multi-part adjustable structure design for the support component and the positioning component. It can be adapted to the existing holes on the tower material of the fixed tower section for installation and can adapt to tower materials of different specifications. The structure is stable, the connection is firm, and it is not easy to loosen or fall off. At the same time, the support component and the positioning component of the docking device can be initially connected, which is convenient for carrying and installation, reduces the probability of scattering during tower climbing and installation, and has high safety.

[0076] Furthermore, the positions of the support component 51, guide 53, and connecting tower 7 relative to the head of the main material of the fixed tower section 3 are adjustable. In one specific embodiment, the support component 51 and guide 53 are located inside the head of the main material of the fixed tower section 3, and the connecting tower 7 is located outside the head of the main material of the fixed tower section 3. The lower end of the guide 53 and the upper part of the connecting tower 7 are spaced apart, and the shape of the lower end of the guide 53 matches and adapts to the shape of the upper inner side of the connecting tower 7. The guide 53 can be adjusted to change the distance between the lower end of the guide 53 and the upper part of the connecting tower 7. By adjusting the position of the guide 53, the distance between the lower end of the guide 53 and the upper part of the connecting tower 7 is slightly greater than the thickness of the foot of the main material of the mounting tower section 4. This allows the foot of the main material of the mounting tower section 4 to slide down along the guide 53 and then fall to connect with the upper part of the connecting tower 7, achieving a better guiding effect.

[0077] like Figure 1 As shown, in the prior art, the relative movement between the main body feet of the mounting tower section 4 is restricted by flexible connection methods such as ropes. However, the restriction effect of the flexible connection method is poor, and the main body feet of the mounting tower section 4 can still generate a certain degree of relative movement. In particular, it cannot effectively restrain the mutual approach between the main body feet of the mounting tower section 4.

[0078] The helicopter tower guidance and positioning system of the present invention further includes a restraint device 6, which is detachably connected to the mounting tower section 4. The restraint device 6 is used to restrict the relative movement between the main members of the mounting tower section 4. The restraint device 6 includes a clamping plate assembly 61 and a second link assembly 62. The clamping plate assembly 61 is detachably connected to the mounting tower section 4 near the main members. The length of the second link assembly 62 is adjustable. The two clamping plate assemblies 61 are connected by at least one (or more) second link assemblies 62 to restrict the relative movement between the main members of the corresponding mounting tower section 4.

[0079] The length of the second link assembly 62 is adjustable. One or more second link assemblies 62 are adapted to rigidly connect two clamping plate assemblies 61 (the number is selected according to the distance between the main material feet of the mounting tower section 4) to restrict the relative movement between the main material feet of the corresponding mounting tower section 4. The rigid connection can restrict the main material feet of the mounting tower section 4 from approaching or moving away from each other, thereby achieving higher restriction stability and accuracy. When used with the docking device 5 of this application, it can form a positive lifting.

[0080] The second link assembly 62 of the constraint device 6 and the first link assembly 54 of the support assembly 51 have similar structures and can be reused, thereby reducing the types of parts and reducing production difficulty and installation complexity.

[0081] Furthermore, such as Figure 2 and Figure 8 As shown, the clamping plate assembly is provided with hanging holes 611 or hooks on the outside of the installation tower section. The hanging holes 611 or hooks are used to connect guide ropes, so that construction personnel can adjust the relative position between the installation tower section 4 and the fixed tower section 3 on the ground with the help of the guide ropes.

[0082] Furthermore, such as Figure 2 and Figure 8 As shown, the clamping plate assembly 61 includes a first clamping plate 612 and a second clamping plate 613, which are clamped and disposed on both sides of the main material foot of the installation tower section 4.

[0083] The first clamping plate 612 and the second clamping plate 613 extend from the mounting tower section 4 at both ends, and are respectively provided with a second connecting hole 6121 and a third connecting hole 6131 to be fastened to each other. They are connected and fixed by clamping, which improves the efficiency of disassembly and assembly while avoiding occupying the original hole positions of the main material foot of the mounting tower section 4.

[0084] The second connecting rod assembly 62 is hinged to the second connecting hole 6121 and / or the third connecting hole 6131, and is connected by the remaining holes on the first clamping plate 612 and / or the second clamping plate 613, reducing structural complexity. The second connecting hole 6121 is a strip hole and the third connecting hole 6131 is a round hole. The length direction of the second connecting hole 6121 is adapted to the thickness direction of the main material foot of the mounting tower section 4, overcoming the problem of difficulty in matching the holes due to processing errors and connection problems.

[0085] like Figure 8 As shown, the clamping plate assembly 61 is provided with a connecting part 6122. Specifically, the first clamping plate 612 located inside the main material foot of the mounting tower section 4 is provided with a connecting part 6122. The connecting part 6122 extends towards the clamping plate assembly 61 on the non-adjacent mounting tower section 4. The second connecting rod assembly 62 connects the main material foot of the non-adjacent mounting tower section 4 through the connecting part 6122. Through multi-directional connection, the restriction effect on the relative movement between the main material feet of the mounting tower section 4 is further improved, and the original structure on the mounting tower section 4 can be avoided, so as to avoid the inability to make a hard connection due to structural interference.

[0086] The constraint device can rigidly connect the tower materials of the installation tower section, constrain the distance between the tower materials of the installation tower section, enhance the structural stability of the tower materials of the installation tower section, reduce deformation and sway, enable the installation tower section and the fixed tower section to make more stable contact and cooperation, reduce docking difficulty, and improve construction efficiency.

[0087] The present invention also provides a tower assembly method, implemented using the helicopter tower assembly guidance and positioning system of the present invention, the tower assembly method comprising:

[0088] S100. Initially assemble docking device 5 on the ground;

[0089] Specifically, in assembling the docking device 5 on the ground, the support component 51 and the positioning component 52 are initially connected so that the support component 51 and the positioning component 52 can move relative to each other to a certain extent, which is convenient for installation but will not completely separate, reducing the probability of some parts falling off during construction. For example, the support component 51 and the positioning seat 521 are initially connected through the adjustment port 5221, and the positioning plate 524 and the positioning seat 521 are initially connected only at one hole.

[0090] S200. Connect the docking device 5 to the main material head of the fixed tower section 3, and connect the connecting tower material 7 to the main material head of the fixed tower section 3.

[0091] Specifically, the device is climbed to the fixed tower section 3, and the docking device 5 is assembled using the original holes (first connecting holes 31 in this invention) on the main material head of the fixed tower section 3. The connecting tower material 7 is then installed, and the remaining holes between the connecting tower material 7 and the main material head of the fixed tower section 3 are connected and locked to ensure a stable connection between the connecting tower material 7 and the main material head of the fixed tower section 3.

[0092] S300. Adjust the position of the guide 53 and the length of the first connecting rod assembly 54 between the guide 53 and the support assembly 51 so that the lower end of the guide 53 and the upper end of the connecting tower material 7 are aligned and connected.

[0093] Specifically, the position of the guide 53 and the length of the first connecting rod assembly 54 between the guide 53 and the support assembly 51 are adjusted so that the lower end of the guide 53 and the upper end of the connecting tower material 7 are aligned and connected. This can be achieved through advance calculation and visual adjustment to ensure that the main material foot of the installation tower section 4 does not interfere with the upper end of the connecting tower material 7.

[0094] S400, Install restraint device 6 on the foot of the main material of the tower section 4 on the ground;

[0095] Specifically, on the ground, a constraint device 6 is installed on the foot of the main material of the installation tower section 4 according to the main material head data of the fixed tower section 3, so that the foot of the main material of the installation tower section 4 can be stably connected with the main material head of the fixed tower section 3.

[0096] S500: Use a helicopter to lift and install tower section 4, and lower the main material foot of tower section 4 to connect with the guide part at the head of the main material of each corresponding fixed tower section 3.

[0097] S600, the helicopter descends appropriately, so that the main material foot of the installation tower section 4 is combined with the connecting tower material 7, and the connecting tower material 7 and the main material foot of the installation tower section 4 are locked, thus completing the fixed connection between the connecting tower material 7 and the installation tower section 4.

[0098] S700, sequentially remove the restraint device 6 and the docking device 5, and connect and lock the holes created by removing the docking device 5 between the main material heads of the connecting tower material 7 and the fixed tower section 3, thus completing the connection between the connecting tower material 7 and the fixed tower section 3.

[0099] The tower erection method of the present invention utilizes an improved helicopter tower erection guidance and positioning system to optimize various operation nodes that are prone to safety risks, reduce the probability of accidents, and achieve efficient and safe helicopter hoisting tower erection operations through orderly operation.

[0100] The above description is merely an illustrative embodiment of the present invention and is not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention.
