Description

Technical Field

[0001] This disclosure relates to the field of tower construction technology, and more specifically to an auxiliary installation device for lattice towers. Background Technology

[0002] As wind turbine blades become increasingly larger and single-unit capacity continues to grow, large-capacity, high-tower onshore wind turbines are becoming the mainstream choice for the future development of the wind power industry. Lattice towers can better meet the requirements of large wind turbines and high towers, and are therefore gradually replacing other types of towers to become the preferred choice in the wind power field.

[0003] The traditional installation method involves workers climbing to the top of the first tower section using climbing spikes after the first section is erected. A crane then hoists the components of the second tower section one by one onto the top of the first section. Workers then connect the components to their corresponding counterparts in the first section while in mid-air, completing the construction of the second tower section. However, as tower heights increase, climbing using climbing spikes becomes risky and inefficient. Furthermore, workers have nowhere to avoid obstacles during hoisting, compromising their safety. Relying solely on limited manpower for high-altitude installation cannot guarantee the efficient and large-scale application of lattice tower technology. Utility Model Content

[0038] When installing existing lattice towers, construction workers reach the tower sections by climbing climbing spikes. As the height of the lattice towers increases, the risk of climbing is greatly increased. Furthermore, during the hoisting of tower sections, construction workers have nowhere to hide and are exposed to the work area for a long time, resulting in very low safety.

[0039] To address the aforementioned technical problems, this embodiment provides an auxiliary installation device for a lattice-type tower. The lattice-type tower extends from the installation surface along the height direction and includes multiple tower sections. The auxiliary installation device includes an auxiliary support and a lifting mechanism. The auxiliary support is disposed on the side of the lattice-type tower and extends along the height direction. The lifting mechanism is movably mounted on the auxiliary support and includes a lifting platform that can move along the auxiliary support in the height direction and is used to carry the construction worker. A working platform is provided on the installed tower section. The lifting platform can move along the auxiliary support to a preset position on the installed tower section, and the lifting platform is configured to be adapted to at least a portion of the working platform, allowing the construction worker to move between the lifting platform and the working platform and connect the installed tower section and the tower section to be installed on the working platform.

[0040] In this implementation scheme, a working platform is provided for the installed upper-level tower section. After the current-level tower section (whole tower section or corner column, etc.) to be installed is hoisted to the top of the upper-level tower section, the lifting mechanism is operated to connect with the working platform so that the construction worker can enter the working platform to complete the connection between the two adjacent tower sections. After the connection is completed, the construction worker returns from the working platform to the lifting mechanism. Thereafter, until the next-level tower section (whole tower section or corner column, etc.) to be installed is hoisted to the top of the current-level tower section, the construction worker stays away from the working platform and the installed tower sections, reducing the risk of accidents due to prolonged exposure to height. Furthermore, the conveying and connecting functions are implemented based on different structural modules. Through the cooperation of the lifting platform and the working platform, the construction worker can be safely and efficiently transported, and a reliable construction space can be provided.

[0041] To make the above-mentioned objectives, features and beneficial effects of this disclosure more apparent and understandable, specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings.

[0042] Figure 1 This is a schematic diagram of the installation of a lattice tower 3 according to an embodiment of this disclosure.

[0043] This implementation scheme can be applied to the field installation and maintenance of lattice tower 3. The lattice tower 3 can be used to support wind turbine generators, but the use of the lattice tower 3 is not specifically limited in this disclosure.

[0044] For ease of description, the height direction of the lattice tower 3 is denoted as the z-direction. Within a plane perpendicular to the z-direction, there are two mutually perpendicular directions: a first direction (denoted as x-direction) and a second direction (denoted as y-direction). The plane perpendicular to the z-direction is denoted as the first plane. In this embodiment, the up and down directions refer to the z-direction and its opposite; below, bottom, or bottom end refers to the direction close to the mounting surface; above, top, or top end refers to the direction towards the sky.

[0045] In embodiments of this disclosure, the lattice tower 3 extends from the mounting surface along the z-direction and includes multiple tower segments 31. For example, the mounting surface can be the ground or any other suitable surface. The lattice tower 3 can be a constant cross-section tower, where each tower segment 31 has the same cross-sectional dimensions in a first plane. The lattice tower 3 can also be a variable cross-section tower, where different tower segments 31 have different dimensions in the first plane, and the cross-sectional dimensions at the top and bottom of the same tower segment 31 along the z-direction are different. For example, the higher the tower segment 31, the smaller its cross-sectional dimensions. The variable cross-section tower can generally have a conical structure.

[0046] The cross-sectional profile of the single-layer tower segment 31 can be quadrilateral, such as... Figure 7 As shown. In practical applications, the cross-sectional shape of a single-layer tower segment 31 can be designed as a polygon with any number of sides, such as a pentagon or hexagon. The total number of multi-layer tower segments 31 can be determined based on the total height of the lattice tower 3 to be constructed. For example, the number of multi-layer tower segments 31 can be any number, such as 10, 15, or 20 layers.

[0047] In embodiments of this disclosure, for each tower segment 31, the tower segment 31 includes a plurality of corner posts 311. The corner posts 311 correspond to the vertices of the cross-sectional profile shape of the tower segment 31. For example, refer to... Figure 1 , Figure 2 and Figure 7The tower segment 31, with a quadrilateral cross-sectional profile, comprises four corner prisms 311, corresponding to the four vertices of the quadrilateral. Each corner prism 311 has a top end 311a and a bottom end 311b along the z-direction. The corner prisms 311 are generally columnar, such as cylinders. In the example where the lattice tower 3 is a constant cross-section tower, the length direction of the corner prisms 311 extends substantially along the z-direction. In the example where the lattice tower 3 is a variable cross-section tower, the length direction of the corner prisms 311 may have a non-zero angle with the z-direction, and multiple corner prisms 311 extend obliquely from the bottom end 311b along the z-direction towards the center of the tower segment 31 in the first plane. The corner prisms 311 at different heights of the tower segment 31 may have the same cross-sectional dimensions.

[0048] In embodiments of this disclosure, the top end 311a of the corner post 311 may include a top flange 312, and the bottom end 311b of the corner post 311 may include a bottom flange 313, such as... Figure 3 As shown.

[0049] In embodiments of this disclosure, the tower segment 31 further includes a plurality of support rods 314 installed between adjacent corner posts 311. For example, three support rods 314 may be installed between adjacent corner posts 311, one of which connects to the top end 311a of the adjacent corner post 311 (this support rod 314 may also be called a top support rod), and the other two support rods 314 obliquely connect the top end 311a of one of the adjacent corner posts 311 to the bottom end 311b of the other (these two support rods 314 may also be called diagonal support rods). The support rods 314 can be connected to the corner posts 311 by fasteners such as bolts.

[0050] For ease of description, the tower segment 31 that has been installed is referred to as the installed tower segment, and the tower segment 31 that has not been installed is referred to as the tower segment to be installed. When multiple installed tower segments have been installed layer by layer on the mounting surface, the highest installed tower segment can also be referred to as the upper-layer tower segment 31A. The tower segment to be installed can also be referred to as the current-layer tower segment 31B. "Installation in place" means that the corner posts 311 and support rods 314 of the current-layer tower segment 31 have been tightened, and the current-layer tower segment 31 has been connected and fixed to the upper-layer tower segment 31A. For example, Figure 1 In the middle, the tower segment 31 located at the highest level along the z direction is being connected to the tower segment 31A of the previous level. Therefore, the tower segment 31 at the highest level is still called the current level tower segment 31B. After the connection is fixed, the tower segment 31 at the highest level can then be called the tower segment 31A of the previous level.

[0051] In some embodiments, the connection between the installed tower section and the tower section to be installed may include the connection between the corner posts of the installed tower section and the corner posts of the tower section to be installed, for example, the connection between the top flange of the corner post of the installed tower section and the bottom flange of the corner post of the tower section to be installed.

[0052] In the embodiments of this disclosure, the installation system may include auxiliary installation equipment 1 and hoisting device 5, wherein the hoisting device 5 may be used to hoist the entire tower section, or to hoist materials of the tower section such as corner columns, support rods, etc., or to hoist the work platform.

[0053] In some embodiments, such as Figure 1 As shown, the hoisting device 5 can hoist the assembled current-level tower segment 31B to the top of the upper-level tower segment 31A as a whole. For example, the hoisting device 5 may include a crane 51 and a lifting mechanism 52. After the current-level tower segment 31B is assembled on the mounting surface (e.g., the ground), the lifting mechanism 52 is connected to the top of the current-level tower segment 31B. The crane 51 lifts the lifting mechanism 52 and then hoists the current-level tower segment 31B from the mounting surface as a whole, raising the current-level tower segment 31B to the target height. The target height is the distance from the top of the upper-level tower segment 31A to the mounting surface.

[0054] In some embodiments, when the current tower segment 31B is assembled in the air in a piecemeal manner, the hoisting device 5 can be used to hoist individual materials such as corner columns 311 and support rods 314. In this example, the hoisting device 5 may include a crane 51.

[0055] In some embodiments, the hoisting device 5 may be disposed on the auxiliary installation equipment 1, such as the top of the auxiliary bracket 1A, thereby improving equipment integration and reducing costs.

[0056] In some embodiments, the work platform 2 may include multiple tower fixing platforms 21 fixed to corner posts 311, for example, corresponding one-to-one with multiple corner posts 311. For each of the multiple tower fixing platforms 21, the tower fixing platform 21 is connected to the top end 311a of the corresponding corner post 311 to support the construction worker in connecting and fixing adjacent tower sections 31. (See reference) Figure 3 and Figure 7 The tower fixing platform 21 can be set on the outside of the corner column 311, such as the top 311a of the corner column 311 on the side away from the center of the tower section 31.

[0057] In some embodiments, the tower fixing platform 21 may include a work area 211 for providing a standing area where workers can stand to perform construction operations. The work area 211 may surround at least three-quarters of the outer perimeter of the corner post 311.

[0058] Furthermore, the tower fixing platform 21 may include a fixing part 213 for connection to the corner post 311. The fixing part 213 may be detachably connected to the corner post 311 by fasteners such as bolts. The fixing part 213 may be arc-shaped and fitted onto the outer surface of the corner post 311.

[0059] Furthermore, optionally, the tower fixing platform 21 may also include support portions 212, with its two ends connected to the fixing portion 213 and the working portion 211 respectively along its extension direction. Multiple support portions 212 may be provided and spaced apart between the fixing portion 213 and the working portion 211. For example, the support portions 212 may include stiffeners. The support portions 212 provide reliable support.

[0060] In some embodiments, when assembling tower segment 31 on the mounting surface, a tower fixing platform 21 can be set on tower segment 31 to obtain a pre-assembled component, which can then be lifted as a whole. For example, after assembling the current layer tower segment 31B on the mounting surface, before lifting the assembled current layer tower segment 31B to the target height, the tower fixing platform 21 can be installed on the current layer tower segment 31B to form a pre-assembled component. Furthermore, the pre-assembled component can be lifted as a whole to the top of the upper layer tower segment 31A, such as... Figure 1 As shown.

[0061] As the pre-assembled components of the current tower segment 31B are hoisted to the target height, and the lifting mechanism 1B of the auxiliary installation equipment 1 reaches the preset position of the upper tower segment 31A (this disclosure does not specifically limit the preset position; a specific position can be selected according to actual needs), the construction worker can enter the tower fixing platform 21 via the lifting mechanism 1B and perform corresponding operations on the tower fixing platform 21 to connect the bottom of the current tower segment 31B and the top of the upper tower segment 31A. Furthermore, the construction worker enters via the lifting mechanism 1B the tower fixing platform 21 located at the top 311a of each corner column 311 of the upper tower segment 31A.

[0062] refer to Figure 1 Before each tower segment 31 is lifted from the installation surface, a tower fixing platform 21 is installed at the top 311a of the corner post 311 of that tower segment 31. When connecting the upper and lower tower segments 31 at the target height, the construction workers enter the tower fixing platform 21 at the top of the lower tower segment 31. In other words, the tower fixing platform 21 is set up in advance when the current tower segment 31B is assembled at the installation surface, and the tower fixing platform 21 set up in advance at the top of the current tower segment 31B is actually put into use when the current tower segment 31B is connected to the next tower segment.

[0063] Therefore, after the current tower segment 31B to be installed is fully assembled on the ground or other installation surfaces and the working platform 2 is set up, it is hoisted onto the already installed upper tower segment 31A. After the lifting mechanism 1B of the auxiliary installation equipment 1 carries the construction personnel to the working platform 2 of the upper tower segment 31A, the connection between the upper and lower tower segments 31 is completed simply by connecting the top end 311a of the corner column 311 of the upper tower segment 31A to the bottom end 311b of the corresponding corner column 311 of the current tower segment 31B. This greatly reduces the difficulty of high-altitude operations for construction personnel and improves construction efficiency.

[0064] In other embodiments, the tower fixing platform 21 can be connected to the top of the tower segment 31 after the entire tower segment 31 has been hoisted to the target height. For example, after the upper-level tower segment 31A is assembled at the mounting surface, it can be hoisted to the target height as a whole, and then the construction personnel can connect the tower fixing platform 21 to the top of the upper-level tower segment 31A. At the same time, the current-level tower segment 31B can be assembled at the mounting surface. Thus, the setup of the work platform 2 and the assembly of the tower segment 31 can be carried out simultaneously in the air and at the mounting surface, improving construction efficiency and reducing the weight of components lifted in a single operation, thereby improving construction safety.

[0065] In other embodiments, the tower segment 31 to be installed can also be assembled in the air using a piecemeal method. The corner posts 311, support rods 314, and other materials of the tower segment 31 to be installed can be hoisted to the top of the already installed tower segment 31. After the lifting mechanism 1B carries the construction personnel to the working platform 2 of the already installed tower segment 31, the corner posts 311 of adjacent tower segments 31 can be connected, and the tower segment 31 to be installed can be assembled using tower climbing nails, safety ropes, etc. In this example, the tower fixing platform 21 can be connected to the corresponding position after the tower segment 31 to be installed is assembled. Alternatively, the tower fixing platform 21 can also be connected to the corresponding position of the corner post 311 on the installation surface before the corresponding corner post 311 is hoisted, so that as the materials of the tower segment 31 to be installed are hoisted to the target height and the connection and assembly between them are completed.

[0066] In some embodiments, reference Figure 1 , Figure 2 and Figure 7 The work platform 2 may also include a connecting platform 22, which is detachably mounted between adjacent tower fixed platforms 21. Thus, the work platform 2 is at least partially continuous on the outer periphery of the current tower segment 31 within a first plane. Workers can move between adjacent tower fixed platforms 21 via the connecting platform 22.

[0067] For example, refer to Figure 7 The four tower fixing platforms 21 can be connected in series to form a closed structure through the communication platform 22. In the first plane, the four communication platforms 22 and the four tower fixing platforms 21 together form a closed quadrilateral structure.

[0068] For example, refer to Figure 11 A connecting platform 22 is provided between some of the adjacent tower fixing platforms 21, while no connecting platform 22 is provided between the remaining adjacent tower fixing platforms 21.

[0069] Furthermore, the length of the connecting platform 22 along its extension direction can be adjusted according to the spacing between adjacent tower fixing platforms 21. For example, but not limited to, the connecting platform 22 may include multiple detachably connected rails, and a corresponding number of rails are connected according to the spacing between adjacent tower fixing platforms 21 on the current tower segment 31B, so that the length of the connecting platform 22 is sufficient to connect the adjacent tower fixing platforms 21.

[0070] In some embodiments, when assembling tower segments 31 on the mounting surface, communication platforms 22 can be provided between tower fixing platforms 21 on the tower segments 31. For example, when assembling the current layer tower segment 31B on the mounting surface, communication platforms are erected between adjacent tower fixing platforms 21, multiple tower fixing platforms 21 are respectively connected to corresponding corner posts 311, and then the length of the communication platform 22 is adjusted and locked according to the spacing between adjacent tower fixing platforms 21. The communication platform 22 is then erected between adjacent tower fixing platforms 21 via a communication platform assembly device. Thus, the pre-assembled component obtained by assembling on the mounting surface includes the current layer tower segment 31B that has been fastened as a whole, tower fixing platforms 21 that are detachably connected to the top ends 311a of each corner post 311, and communication platforms connecting adjacent tower fixing platforms 21.

[0071] As the pre-assembled components of the current tower segment 31B are hoisted to the target height, and the lifting mechanism 1B of the auxiliary installation equipment 1 reaches the preset position of the upper tower segment 31A, the construction workers can enter the connecting platform 22 of the upper tower segment 31B via the lifting mechanism 1B, and then enter the tower fixing platform 21 of the upper tower segment 31B via the connecting platform 22 to connect the bottom of the current tower segment 31B with the top of the upper tower segment 31A. Thus, most of the component installation operations are completed on the installation surface, reducing the workload of high-altitude work and improving construction safety.

[0072] In one variation, the method of setting up the communication platform 22 may include placing the communication platform 22 between adjacent tower fixing platforms 21 after the tower segment to be installed is hoisted to the top of the installed tower segment. The tower segment to be installed can be a whole tower segment or a collection of disassembled tower segments. For example, after the pre-assembled components of the current tower segment 31B are hoisted to the top of the upper tower segment 31A, the lifting mechanism 1B carrying the communication platform 22 can be moved to a preset position on the upper tower segment 31A, and the construction personnel can then erect the communication platform 22 between adjacent tower fixing platforms 21 on the upper tower segment 31A. This reduces the weight of the pre-assembled components, lessens the lifting load on the hoisting device 5, and reduces the difficulty of hoisting.

[0073] In one specific implementation, after completing the connection between the current tower segment 31B and the upper tower segment 31A, at least a portion of the working platform 2 installed on the upper tower segment 31A can be dismantled. For example, after the construction worker completes the connection operation of the tower fixing platform 21 installed at the top 311a of each corner column 311 of the upper tower segment 31A, at least the connecting platform 22 connecting adjacent tower fixing platforms 21 can be dismantled. As another example, the tower fixing platform 21 installed on the upper tower segment 31A can be dismantled.

[0074] Furthermore, at least a portion of the working platform 2 dismantled from the previous tower segment 31A can be installed on other tower segments 31. For example, multiple tower fixing platforms 21 dismantled from the previous tower segment 31A can be installed on the current tower segment 31B being assembled on the installation surface via a tower fixing platform assembly device. Thus, the working platform 2 can be reused repeatedly, saving materials and improving construction efficiency.

[0075] In a specific implementation, refer to Figures 4 to 7 The auxiliary installation device 1 may include an auxiliary support 1A, disposed on the side of the lattice tower 3 and extending along the z-direction. For example, refer to Figure 7 In the first plane, the auxiliary support 1A is set on one side of the lattice tower 3. For ease of description, the direction in which the auxiliary support 1A points to the lattice tower 3 is called the second direction (y direction), and the direction that is perpendicular to both the z direction and the second direction is called the first direction (x direction).

[0076] The auxiliary support 1A can be a support frame with a certain cross-sectional area. For example, but not limited to, the auxiliary support 1A can include a guide support column that extends along the z-direction and is supported on the mounting surface. The guide support column can be a truss structure formed by welding square tubes and / or round tubes. The auxiliary support 1A adopts a large-section guide support truss column structure, which can ensure that the rigidity and strength of the structure itself can meet the stress requirements of the lifting platform.

[0077] Furthermore, the auxiliary installation equipment 1 may also include a lifting mechanism 1B, which is movably mounted on the auxiliary support 1A.

[0078] The lifting mechanism 1B may include a lifting platform 11, movable in the z-direction along the auxiliary support 1A and used to carry construction workers. The lifting platform 11 can move along the auxiliary support 1A to a preset position of the installed tower section. For example, in combination with... Figure 1The lifting platform 11 can initially remain at position L1, that is, at the top of tower segment 31 below the upper tower segment 31A. After the corner post 311 of the current tower segment 31B is connected to the corner post 311 of the upper tower segment 31A, the lifting platform 11 can be operated to rise from position L1 to position L2 along the auxiliary support 1A, that is, at the top of the upper tower segment 31A. After the lifting platform 11 reaches position L2, the operator can enter the working platform 2 from the lifting platform 11 to perform the connection operation between the upper tower segment 31A and the current tower segment 31B. In this disclosure, the preset position of the installed tower segment can be determined as needed. For example, the preset position may include the top of the upper tower segment 31A, that is, the position near the current tower segment 31B; or, for example, the preset position may include any position of the upper tower segment 31A, as long as the operator can directly or indirectly enter the working platform 2 from the lifting platform 11.

[0079] In some embodiments, the lifting platform 11 can also be used to transport materials, such as the support rod 314 of the tower section 31, the tower fixing platform 21, the communication platform 22, etc.

[0080] In some embodiments, a working platform 2 is provided on the upper tower segment 31A, and a lifting platform 11 is configured to adapt to at least a portion of the working platform 2, allowing the worker to move between the lifting platform 11 and the working platform 2 and connect the upper tower segment 31A and the current tower segment 31B on the working platform 2. In this example, the lifting platform 11 is used to transport the worker along the z-direction. As the lifting platform 11 moves to a preset position on the upper tower segment 31A, the worker can enter the working platform 2 via the lifting platform 11 and perform connection operations on the adjacent tower segment 31 on the working platform 2. Thus, the conveying function and the connection function are implemented based on different structural modules. Through the cooperation of the lifting platform 11 and the working platform 2, the worker is safely and efficiently transported and a reliable construction space is provided.

[0081] For example, refer to Figure 1 The upper-level tower segment 31A has a working platform 2 installed on it. For example, the working platform 2 is at least partially installed on the upper-level tower segment 31A during its assembly on the mounting surface, and is hoisted and installed to the target height along with the upper-level tower segment 31A. When the lifting mechanism reaches the preset position of the upper-level tower segment, the worker can perform construction operations on the working platform 2 to connect the top ends 311a of each corner column 311 of the upper-level tower segment 31A to the bottom ends 311b of the corresponding corner column 311 of the current-level tower segment 31B. In this example, the lifting platform 11 serves as a standing platform for the worker. As the lifting platform 11 moves to the preset position of the upper-level tower segment 31A, the worker can enter the working platform 2 via the lifting platform 11 and perform connection operations on the working platform 2.

[0082] In some embodiments, after connecting the upper tower segment 31A and the current tower segment 31B, the lifting mechanism 1B can be operated to leave the upper tower segment 31A. The worker returns from the work platform 2 to the lifting mechanism 1B before the lifting mechanism 1B leaves the upper tower segment 31A. That is, the worker is only on the work platform 2 during the actual connection operation; at all other times, the worker is on the lifting mechanism 1B. During these other time periods, the next tower segment can be hoisted to the top of the current tower segment 31B.

[0083] For example, refer to Figure 1 After the current tower segment 31B is hoisted to the top of the previous tower segment 31A, the operating lifting platform 11 moves along the z-direction to position L2 and docks with the working platform 2 in the first plane, allowing the construction worker to enter the working platform 2 to complete the connection between the two adjacent tower segments 31. After the connection is completed, the construction worker returns from the working platform 2 to the lifting platform 11. Optionally, the lifting platform 11 can disconnect from the working platform 2 in the first plane. Before the next tower segment is hoisted to the top of the current tower segment 31B, the position of the lifting platform 11 in the z-direction remains unchanged, i.e., it stays at position L2. Before the next tower segment is hoisted into place, the lifting platform 11 carrying the construction worker is located at a lower position, L2, reducing the probability of collision with the lifting platform 11 during the hoisting of the next tower segment and during the transition from the next tower segment to the current tower segment 31B. This further ensures construction safety.

[0084] For example, refer to Figure 1 After the current tower segment 31B is hoisted to the top of the previous tower segment 31A, the lifting platform 11 is moved along the z-direction to position L2 and docked with the working platform 2 in the first plane, allowing the construction worker to enter the working platform 2 to complete the connection between the two adjacent tower segments 31. After the connection is completed, the construction worker returns from the working platform 2 to the lifting platform 11. Optionally, the lifting platform 11 can disconnect from the working platform 2 in the first plane. Then, during the assembly of the next tower segment on the installation surface, the lifting platform 11 can be moved along the z-direction to position L3, i.e., the top of the current tower segment 31B, where the construction worker can wait for the next tower segment to be hoisted into place. This improves construction efficiency.

[0085] Therefore, the auxiliary installation equipment 1 provides construction workers with a mobile and high-altitude safety platform. With the support of the lifting platform 11, construction workers can safely and efficiently reach the construction tower section without having to climb long distances at high altitudes. Through the cooperation of the work platform 2 and the lifting platform 11, after the current tower section 31B is connected to the previous tower section 31A, until the next tower section to be installed is hoisted to the top of the current tower section 31B, construction workers remain away from the work platform 2 and the installed tower sections. This helps reduce the risk of accidents caused by prolonged exposure to high altitudes.

[0086] In one specific implementation, the adaptation of the lifting platform 11 and the working platform 2 may include the adaptation of the lifting platform 11 and the working platform 2 in terms of distance. The distance may be the distance of the lifting platform 11 towards the tower section 31. By controlling the adaptation of the lifting platform 11 and the working platform 2 in terms of distance, so that the two form a docking relationship or an adjacent relationship, the construction worker can safely move between the lifting platform 11 and the working platform 2.

[0087] Furthermore, at least a portion of the lifting platform 11 can be configured to be at a distance less than a preset value from at least a portion of the working platform 2 of each installed tower segment within a first plane. The preset value can be specifically determined based on empirical values. For example, the preset value may be defined as the distance that allows a worker to safely enter the working platform 2.

[0088] For a lifting platform 11 extending circumferentially along the lattice tower 3, this distance can refer to the distance in the x-direction between the overlapping portion of the lifting platform 11 and the working platform 2 in the y-direction. (Reference) Figures 7 to 11 If the length of the lifting platform 11 extending along the y direction is not less than the distance from the top tower section to the auxiliary support 1A, and the distance between the end of the lifting platform 11 away from the auxiliary support 1A along the y direction and the working platform 2 set in the upper tower section 31A in the x direction is less than a preset value, it can be determined that the lifting platform 11 is compatible with the working platform 2.

[0089] For the lifting platform 11 extending along the y-direction from the auxiliary support 1A towards the lattice tower 3, this distance can refer to the distance between the lifting platform 11 and the working platform 2 in the y-direction. (Reference) Figure 12 When the distance from the end of the lifting platform 11 extending along the y direction from the auxiliary support 1A to the tower section 31 at the same height is less than a preset value, it is determined that the lifting platform 11 is compatible with the working platform 2 set on the tower section 31 of that floor.

[0090] In some embodiments, the cross-sectional dimensions of the tower segments 31 at different heights are different, and at least a portion of the lifting platform 11 can move toward the working platform 2 in a first plane, such that the distance between at least a portion of the lifting platform 11 and at least a portion of the working platform 2 in the first plane is less than a preset value. For example, the lifting platform 11 can be adjusted according to the cross-sectional dimensions of the upper-level tower segment 31A, so that the distance between the lifting platform 11 and the working platform 2 located on that level of tower segment 31 is less than a preset value. Thus, for a variable cross-section tower, the movement of the lifting platform 11 can be adapted to the cross-sectional dimensions of different levels of tower segments 31, thereby achieving reliable adaptation between the lifting platform 11 and different levels of tower segments 31.

[0091] For the lifting platform 11 extending circumferentially along the lattice tower 3, refer to Figure 1 and Figure 7 After the lifting platform 11 rises from position L1 to position L2, as the cross-sectional dimension of the tower segment 31 to be adapted decreases, the surrounding structure formed by the lifting platform 11 extending in the first plane correspondingly contracts inward to fit as closely as possible to the cross-sectional dimension of the tower segment 31 located at position L2. For example, the length of the lifting platform 11 extending in the x-direction can be reduced, or the section of the lifting platform 11 extending in the y-direction can be manipulated to move as a whole towards the tower segment 31 in the x-direction. Alternatively, the length extending in the y-direction can be increased.

[0092] For the lifting platform 11 extending along the y-direction from the auxiliary support 1A toward the lattice tower 3, refer to Figure 12 After the lifting platform 11 rises from position L1 to position L2, as the cross-sectional dimensions of the tower section 31 to be adapted to decrease, the length of the lifting platform 11 extending in the y-direction increases. Therefore, the lifting platform 11 at any height can flexibly adapt to changes in the cross-sectional dimensions of the tower section 31 at the same height, ensuring reliable docking between the lifting platform 11 and the working platform 2 installed on any layer of the tower section 31.

[0093] In a specific implementation, refer to Figures 4 to 11 The lifting platform 11 may include one or more arms 111 extending circumferentially along the installed tower section, such as two arms 111, three arms 111, etc. In some examples, at least one arm 111 may be less than a preset value in the distance between itself and at least a portion of the working platform 2 of the installed tower section in a first plane, or, in the case where the cross-sectional dimensions of the tower sections at different heights are different, at least one arm 111 may be moved toward the working platform in the first plane such that the distance between itself and at least a portion of the working platform 2 in the first plane is less than a preset value. For example, the aforementioned at least one arm 111 may include the last arm 111, that is, the arm 111 farthest from the auxiliary support 1A among the arms 111 connected sequentially along the extension direction of the lifting platform 11.

[0094] In some examples, such as Figures 7 to 9 As shown, at least one arm 111 may include a first arm 1111 extending along the x-direction around the periphery of the lattice tower 3, and a second arm 1112, i.e., the last arm 111, connecting the first arm 1111 and extending along the y-direction. In one example, the distance along the x-direction between the second arm 1112 and the working platform 2 of the installed tower section is less than a preset value. In another example, the length or position of the first arm 1111 along the x-direction is adjustable. For example, the length of the first arm 1111 extending along the x-direction from the auxiliary support 1A can be lengthened or shortened as needed. Alternatively, the first arm 1111 itself has a fixed extension length and can move relative to the auxiliary support 1A in the x-direction. Adjusting the length or position of the first arm 1111 allows the second arm 1112 to move toward or away from the working platform 2, thereby adjusting the distance between the second arm 1112 and the working platform 2. In yet another example, the second arm 1112 can move in a first plane toward or toward the tower section 31 to adapt to the working platform 2 installed on each layer of the tower section 31. For example, the position of the second arm 1112 along the x-direction is adjustable so that the second arm 1112 moves toward the work platform 2.

[0095] In some embodiments, at least one arm 111 of the lifting platform 11, such as the last arm 111, is configured to extend in the circumferential direction of the lattice tower to be compatible with the tower fixing platform at the same position for each installed tower segment. Further, to accommodate the cross-sectional dimensions of the tower segments 31 at different heights, the length or position of at least one arm 111 of the lifting platform 11 in the circumferential direction of the lattice tower 3 can be adjusted to adapt to the tower fixing platform at the same position for each installed tower segment. For example, the extension length of the last arm 111 or its position relative to the lattice tower 3 in a first plane can be adjusted to adapt it to the tower fixing platform at the same position for each installed tower segment.

[0096] In adjacent installed tower sections, the tower fixing platforms 21 installed on the upper and lower corner columns 311 that are connected can be considered as tower fixing platforms 21 at the same location. (Reference) Figure 1 In the current tower segment 31B and the previous tower segment 31A that have been hoisted into the lattice tower 3, the tower fixing platforms 21 installed on the two corner columns 311 connected in the z-direction are tower fixing platforms 21 at the same position. Further, the tower fixing platforms 21 at the same position in each installed tower segment refer to the tower fixing platforms 21 installed on the corner columns 311 connected sequentially in the z-direction of each installed tower segment. Combined with... Figure 7 Each tower section 31 in Figure 7 If the corner posts 311 located at the upper left corner are connected in sequence, then the tower fixing platforms 21 set on these corner posts 311 are tower fixing platforms 21 in the same position.

[0097] In some examples, such as Figure 7 As shown, when the lifting platform 11 is in position L1, the extension length of the second arm 1112 along the y-direction is adapted to ensure that the projection of the second arm 1112 along the x-direction at least covers the tower fixing platform 21 of the corner post 311 located at the upper left corner of the upper tower segment 31A. As the lifting platform 11 moves from position L1 to position L2 along the z-direction, the extension length of the second arm 1112 along the y-direction is adapted to ensure that the projection of the second arm 1112 along the x-direction at least covers the tower fixing platform 21 of the corner post 311 located at the upper left corner of the current tower segment 31B. In some embodiments, the second arm 1112 may be adjacent to the tower fixing platform 21 in the x-direction, allowing workers to enter or exit the tower fixing platform 21 via the second arm 1112.

[0098] Furthermore, depending on the different layouts of the lifting platform 11 and the working platform 2, the last boom 111 can be adapted to the tower fixing platform 21 furthest from the auxiliary support 1A, such as... Figure 8 As shown. Alternatively, the last arm 111 can also be adapted to the tower fixing platform 21 closest to the auxiliary support 1A, such as... Figure 7 As shown.

[0099] This ensures that the extension length of the lifting platform 11, which extends circumferentially along the lattice tower 3, is sufficient to connect with the working platform 2 of each tower section 31.

[0100] In some embodiments, for a constant cross-section tower, the extension length of the last arm 111 in at least one arm 111 along the circumference of the lattice tower 3 can remain constant. When the lifting platform 11 is adapted to different tower sections 31, movement only occurs in the z-direction.

[0101] In some embodiments, the cross-sectional dimensions of the tower segments 31 at different heights are different, and the last arm 111 is telescopic or position-adjustable in the circumferential extension direction along the lattice tower 3 to adapt to the tower fixing platform 21 at the same position of each installed tower segment. Telescopic means that the length of the last arm 111 along the extension direction is adjustable. Position-adjustable means that the last arm 111 as a whole can translate within a first plane to change its position in the circumferential extension direction.

[0102] For example, continue to refer to Figure 7The distance from the tower fixing platform 21 of the upper left corner post 111 of the upper-level tower segment 31A to the auxiliary support 1A is less than the distance from the tower fixing platform 21 of the upper left corner post 111 of the current-level tower segment 31B to the auxiliary support 1A. Correspondingly, after the lifting platform 11 moves from position L1 to position L2, the second arm 1112 can be moved along the x-direction to approach the tower fixing platform 21 located at the upper left corner post 111 of the current-level tower segment 31B. Furthermore, the length of the second arm 1112 can be extended along the y-direction to ensure that the overlapping area between the projection of the second arm 1112 along the x-direction and the tower fixing platform 21 located at the upper left corner post 111 of the current-level tower segment 31B is sufficient for the worker to pass through.

[0103] In some embodiments, the last arm 111 of the lifting platform 11 may be provided with an extension section 114, which is configured to extend toward the work platform 2 to reduce the distance between the last arm 111 and the work platform 2.

[0104] In one example, such as Figure 7 As shown, the end of the second arm 1112 furthest from the first arm 1111 may be provided with an extension segment 114 extending in the x-direction for docking the second arm 1112 and the tower fixing platform 21. The operator moves between the second arm 1112 and the tower fixing platform 21 via the extension segment 114. Non-limitingly, the extension segment 114 may be hinged to the end of the second arm 1112. The hinge axis may be parallel to the y-direction. The extension segment 114 may rotate about the hinge axis in the plane formed by the z-direction and the x-direction. The extension segment 114 may rotate about the hinge axis between a folded position and an unfolded position; the folded position can be referenced... Figure 4 The viewing angle is located at the position of the extension section 114 on the right side of the auxiliary support 1A. The unfolded position can be referenced. Figure 4 The viewpoint is located at the position of the extension segment 114 on the left side of the auxiliary support 1A.

[0105] For variable cross-section towers, during the construction of lower-level tower sections 31, the extension section 114 can be in a folded position, and adjusting the second arm 1112 can maintain the distance between the second arm 1112 and each working platform 2 within a preset value. However, as the number of installed tower sections increases, the cross-sectional dimension of the upper-level tower section 31A gradually decreases. Simply adjusting the length or position of the first arm 1111 along the x-direction and the position of the second arm 1112 along the x-direction may not be enough to reduce the distance between the second arm 1112 and the working platform 2 to within the preset value. For example, adjusting the second arm 1112 in the first plane to such a position... Figure 7 In the position shown, if the second arm 1112 is still a certain distance from the tower fixing platform 21 in the x direction, the extension section 114 can be switched to the unfolded position to shorten the distance between the second arm 1112 and the working platform 2 in the x direction to within the preset value.

[0106] Therefore, the extension section 114 can serve as an extension of the last arm 111 in at least one arm 111, ensuring that the lifting platform 2 can be reliably adapted to the working platform 2 of the tower section 31 at any height.

[0107] In a specific implementation, refer to Figure 10 The cross-section of the installed tower section equipped with the working platform 2 can be polygonal. In this example, the lifting platform 11 may include multiple arms 111 extending circumferentially along the installed tower section, and adjacent arms 111 are hinged together. The multiple arms 111 may correspond to multiple sides of the polygon, and the included angle of adjacent arms 111 can be adjusted according to the included angle of adjacent sides in the corresponding polygon.

[0108] Furthermore, one of the adjacent arms 111 can be rotated relative to the other so that the plurality of arms 111 extend along at least a portion of the outer contour of the polygon in the first plane. Thus, each arm 111 is adapted to a tower fixing platform 21 provided on the corresponding side, and the construction worker can enter any tower fixing platform 21 of the current tower segment 31B along the hinged plurality of arms 111 to carry out construction operations.

[0109] In some embodiments, continue to refer to Figure 10 Of the two hinged arms 111, the arm 111 furthest from the auxiliary support 1A can rotate around the hinge point to be parallel to the other arm 111, and retract along the extension direction of the other arm 111 to above or below it. Thus, the multiple arms 111 of the lifting platform 11 can retract to their shortest distance step by step and then move as a whole in the z-direction, reducing the size of the lifting platform 11 exposed at height and further reducing safety risks. The shortest distance can be the extension length of the first arm 111 among the multiple arms 111.

[0110] Furthermore, after the lifting platform 11 moves along the auxiliary support 1A to a preset position such as the upper tower segment 31A, multiple arms 111 are operated to extend in multiple stages to adapt to the tower fixing platform 21 set on the corresponding side of the upper tower segment 31A in the circumferential direction. Thus, as the lifting platform 11 moves along the z-direction to the preset position, each arm 111 is operated to extend, retract, or adjust its position to adapt to the corresponding tower fixing platform 21, allowing the construction worker to enter the corresponding tower fixing platform 21 from the lifting platform 11.

[0111] In one specific implementation, the adaptation between the lifting platform 11 and the work platform 2 may include the adaptation of their layout. (See reference) Figure 7 , Figure 8 and Figure 11 The auxiliary support 1A can be set on one side of the lattice tower 3 and includes one or more lifting platforms 11. Figure 7 , Figure 8and Figure 11 The examples shown all use auxiliary support 1A, which includes two lifting platforms 11. Each auxiliary support can support two lifting platforms to maintain balance. In practical applications, auxiliary support 1A may also include one, three, or more lifting platforms 11.

[0112] In some embodiments, one or more lifting platforms 11 may be configured to be compatible with all tower fixing platforms 21 of the installed tower section. Workers can enter or exit any of the multiple tower fixing platforms 21 via the lifting platform 11.

[0113] For example, refer to Figure 8 Two lifting platforms 11 are symmetrically arranged on both sides of the auxiliary support 1A along the x-direction, with each lifting platform 11 being adapted to each tower fixing platform 21 located on the same side. Specifically, the extension length of the second arm 1112 of the lifting platform 11 along the y-direction is sufficient to reach the tower fixing platform 21 furthest from the auxiliary support 1A in the y-direction. All tower fixing platforms 21 located along the extension path of the second arm 1112 are adapted to the second arm 1112.

[0114] In this example, the communication platform 22 can be eliminated. Workers can access any of the tower fixing platforms 21 located on the tower section 31 via the lifting platform 11. Each tower fixing platform 11 corresponds to a corner post 311, and one or more lifting platforms 11 can be used to connect to all the tower fixing platforms 21 on the tower section 31. For example, Figure 8 Each of the two lifting platforms 11 corresponds to two of the four tower fixing platforms 21. Thus, the construction worker enters each tower fixing platform 21 via the lifting platform 11 to connect the corner column 311 of the upper tower segment 31A on which the tower fixing platform 21 is located with the corresponding corner column 311 of the current tower segment 31B located above it.

[0115] In some embodiments, one or more lifting platforms 11 may be configured to adapt to a portion of the multiple tower fixing platforms 21. The remaining tower fixing platforms 21 are connected to the portion of the tower fixing platforms 21 via a connecting platform 22. The lifting platform 11 only needs to adapt to a portion or even one tower fixing platform 21 of each tower segment 31. After the worker enters the adapted tower fixing platform 21 via the lifting platform 11, they can freely and smoothly reach any other tower fixing platform 21 of that tower segment 31 via the connecting platform 22. The use of the connecting platform 22 reduces the length of the lifting platform 11 and improves its aerial stability. Furthermore, during the lifting of the current tower segment 31B, the connecting platform 22 can also provide a safe space for the worker.

[0116] For example, refer to Figure 7 Two lifting platforms 11 are symmetrically arranged on both sides of the auxiliary support 1A along the x-direction, wherein each lifting platform 11 is adapted to the tower fixing platform 21 of the tower segment 31 closest to the auxiliary support 1A. Furthermore, a connecting platform 22 can be arranged at least between the tower fixing platform 21 farther from the auxiliary support 1A and the tower fixing platform 21 located behind it along the y-direction. After the construction worker enters the tower fixing platform 21 closer to the auxiliary support 1A in the y-direction via the lifting platform 11, they can enter other tower fixing platforms 21 farther from the auxiliary support 1A via the connecting platform to connect the top end 311a of each corner column 311 of the upper-level tower segment 31A with the bottom end 311b of each corner column 311 of the current-level tower segment 31B.

[0117] Furthermore, in such Figure 7 In the layout of the lifting platform 11 and the working platform 2 shown, a connecting platform 22 can be provided between any two adjacent tower fixing platforms 21 of a single-layer tower section 31. Thus, after the construction worker enters the tower fixing platform 21 near the auxiliary support 1A in the y-direction via the lifting platform 11, they can smoothly move around the circumference of the next layer of tower section 31A, improving the worker's operational flexibility.

[0118] For example, refer to Figure 11 Two lifting platforms 11 are symmetrically arranged on both sides of the auxiliary support 1A along the x-direction. Each lifting platform 11 is adapted to a connecting platform 22 located on the same side, and to a tower fixing platform 21 located between the connecting platform 22 and the auxiliary support 1A. The tower fixing platform 21 located on the side of the connecting platform 22 facing away from the auxiliary support 1A is not directly adapted to the second arm 1112. Workers access the more distant tower fixing platform 21 via the connecting platform 22. Therefore, the extension length of the second arm 1112 can be controlled within a suitable range, avoiding the risk of overturning of the auxiliary support 1A due to excessive extension length forming a cantilever beam, thus improving construction safety.

[0119] Therefore, based on the relative positions of the tower fixing platform 21 and the auxiliary support 1A that the lifting platform 11 is specifically adapted to, it can be determined whether a connecting platform 22 should be erected between adjacent tower fixing platforms 21. In practical applications, the layout and combination of the lifting platform 11 and the working platform 2 can be flexibly determined according to the on-site construction conditions, resulting in greater construction flexibility.

[0120] In some embodiments, two lifting platforms 11 are respectively disposed on opposite sides of the same auxiliary support 1A, and the two lifting platforms 11 can be raised and lowered independently. For example, refer to Figure 5Two lifting platforms 11 share an auxiliary support 1A and are respectively located on both sides of the auxiliary support 1A along the x-direction. Independent lifting components 12 are installed on both sides of the auxiliary support 1A, allowing each of the two lifting platforms 11 to rise and fall independently along the z-direction. For example, the two lifting platforms 11 can rise or fall synchronously, or one can rise while the other falls as needed. For example, each lifting platform 11 is independently equipped with a set of lifting components 12 to control its movement. This increases the flexibility during assembly and construction, allowing multiple groups of workers to work at different heights simultaneously. For example, one group of workers operates one lifting platform 11 to position L2 to connect the upper tower segment 31A and the current tower segment 31B, while another group of workers operates another lifting platform 11 to position L3 to erect a connecting platform 22 between adjacent tower fixing platforms 21 of the current tower segment 31B. This further improves overall installation efficiency.

[0121] Furthermore, the two lifting platforms 11 can extend symmetrically within a first plane, with their axes of symmetry parallel to the y-direction and passing through the center of the auxiliary support 1A and the center of the lattice tower 3. For example, refer to... Figure 7 Two L-shaped lifting platforms 11 extend symmetrically from the auxiliary support 1A toward the lattice tower 3 in a circumferential direction. The first arms 1111 of the two lifting platforms 11 extend opposite each other from the auxiliary support 1A in the x-direction, and the second arms 1112 of the two lifting platforms 11 extend from their respective first arms 1111 in the y-direction to both sides of the installed tower section in the x-direction.

[0122] In some embodiments, the two lifting platforms 11 may extend to the same length around the lattice tower 3 in the first plane. For example, continuing to refer to Figure 7 The distances from the tower fixing platform 21 to the auxiliary support 1A of each of the two lifting platforms 11 are equal.

[0123] In one variation, the two lifting platforms 11 may extend to different lengths around the lattice tower 3 in the first plane. For example, one of the two lifting platforms 11 may be adapted to the tower fixing platform 21 of the upper tower segment 31A that is closest to the auxiliary support 1A, while the other may be adapted to the tower fixing platform 21 of the upper tower segment 31A that is furthest from the auxiliary support 1A.

[0124] In one specific implementation, the adaptation between the lifting platform 11 and the working platform 2 may include layout adaptation between the lifting platform 11 and the working platform 2. The number of auxiliary supports 1A can be multiple, and they are respectively arranged on different sides of the lattice tower 3. For example, refer to... Figure 9 Auxiliary supports 1A can be installed on both sides of the lattice tower 3 along the y direction.

[0125] Furthermore, each auxiliary support 1A may include one or more lifting platforms 11. For example, continuing to refer to Figure 9 Each auxiliary support 1A has two lifting platforms 11 symmetrically arranged along the x-direction. A total of four lifting platforms 11 are arranged around or at least partially around the circumference of the lattice tower 3 in the first plane.

[0126] Furthermore, one or more lifting platforms 11 may be configured to adapt to a portion of the multiple tower fixing platforms 21 of the installed tower segment. In some embodiments, the collection of one or more tower fixing platforms 21 adapted to each lifting platform 11 covers all tower fixing platforms 21 of a single-layer tower segment 31, such as... Figure 9 As shown. In this example, the communication platform 22 can be eliminated. In some embodiments, among the multiple tower fixing platforms 21 of the installed tower segment, at least one tower fixing platform 21 may not have a matching lifting platform 11, but is connected to an adjacent tower fixing platform 21 that has a matching lifting platform 11 via the communication platform 22.

[0127] In a specific implementation, refer to Figures 4 to 6 The lifting mechanism 1B may include a lifting assembly 12, which is connected to the auxiliary support 1A and the lifting platform 11 respectively. The lifting assembly 12 can be used to drive the lifting platform 11 to move along the auxiliary support 1A. Figure 1 In the middle, the lifting component 12 can be operated to move along the auxiliary support 1A to move the lifting platform 11 to the preset position of the upper tower section 31A.

[0128] There are several ways in which the lifting assembly 12 and the auxiliary support 1A can cooperate. For example, the auxiliary support 1A can be formed as a lattice frame, and the lifting assembly 12 can include a lifting sleeve and a hydraulic lifting assembly. The lifting sleeve is fitted outside the auxiliary support 1A and is movably connected to the auxiliary support 1A along the height direction. The lifting sleeve and the hydraulic lifting assembly are respectively provided with locking buckles that can be engaged with the auxiliary support 1A. During the lifting process, the lifting sleeve is released from engagement with the auxiliary support 1A, and the hydraulic lifting assembly engages with the auxiliary support 1A to drive the lifting sleeve to lift. Another example is that the lifting assembly 12 is provided with a lifting gear, and the auxiliary support 1A is provided with a lifting rack extending along the height direction. The lifting gear and the lifting rack mesh with each other. Yet another example is that the top of the auxiliary support 1A is provided with a lifting system, which is connected to the lifting assembly 12 to drive the lifting assembly 12 to move along the height direction.

[0129] Furthermore, the lifting platform 11 can be hinged to the lifting assembly 12, and the hinge axis lies in the first plane. The hinge only transmits vertical traction force, and other loads are not transmitted to the lifting assembly 12 body, thus avoiding normal deformation of the lifting assembly 12 due to complex external forces. In scenarios where the lifting assembly 12 adopts a gear and rack traction structure, this hinged connection method helps to ensure a good meshing relationship between the gear 1233 and the rack 1234.

[0130] Furthermore, the lifting assembly 12 may include a fixed bracket 121 connected to the lifting platform 11. A guide portion 122 and a drive portion 123 may be provided on the fixed bracket 121.

[0131] The guide portion 122 can slide in conjunction with the guide rail 14 disposed on the auxiliary support 1A. For example, the guide rails 14 are arranged in pairs on the auxiliary support 1A along the y-direction and extend along the z-direction. The two edges of the lifting platform 11 facing the auxiliary support 1A in the y-direction are respectively connected to the corresponding guide rails 14 via the guide portion 122. For example, the guide portion 122 can be embedded in the track groove of the guide rail 14 to drive the lifting platform 11 to move along the extension direction of the guide rail 14. As another example, the guide portion 122 can hold the guide rail 14 disposed on the auxiliary support 1A through two sets of C-shaped roller systems to move up and down along the auxiliary support 1A.

[0132] The drive unit 123 can be used to drive the guide unit 122 to slide along the guide rail 14. For example, see reference. Figure 4 and Figure 6 The drive unit 123 may include a dual-output shaft geared motor 1231, a transmission shaft 1232, and gears 1233 located on both sides of the dual-output shaft geared motor 1231. The gears 1233 may be located at both ends of the transmission shaft 1232 along its extension direction, that is, on both sides of the dual-output shaft geared motor 1231 along the y-direction. Furthermore, the dual-output shaft geared motor 1231 can drive the gears 1233 to move relative to the double-row racks 1234 on the auxiliary support 1A via the transmission shaft 1232. The two rows of racks 1234 may be spaced apart along the y-direction on the auxiliary support 1A, corresponding one-to-one with two guide rails 14 spaced apart along the y-direction. High-strength guide rails 14 and racks are arranged on both sides of the auxiliary support 1A along the y-direction, maintaining a close distance between the guide rails 14 and the racks to ensure that the lifting force of the gears 1233 is minimized when driven by the gears 1233. The dual-output shaft geared motor 1231 adopts a single geared motor with dual outputs to ensure that the two gears 1233 lift synchronously, thereby improving the stability and safety of the equipment.

[0133] In one specific implementation, during the process of the lifting assembly 12 driving the lifting platform 11 to move along the z-direction to a preset position of the upper tower segment 31A, or after the lifting assembly 12 has driven the lifting platform 11 to move along the z-direction to the preset position of the upper tower segment 31A, the distance between the lifting platform 11 and the working platform 2 can be adjusted in the first plane to allow the worker to enter the working platform 2 from the lifting platform 11. For example, at least one arm 111 can be brought closer to the working platform 2 so that the last arm 111 is adapted to the tower fixing platform 21 or the connecting platform 22. As another example, the length or position of the first arm 1111 along the x-direction can be adjusted, and / or the position of the second arm 1112 along the x-direction can be adjusted so that the second arm 1112 is brought closer to the working platform 2.

[0134] In a specific implementation, refer to Figures 4 to 6 The first arm 1111 may include a lifting frame 112 and a box-type telescopic boom 113. The lifting frame 112 may be connected to the lifting assembly 12 and includes a base 1121. After the worker leaves the work platform 2, they may remain in the area provided by the lifting frame 112 until the lifting platform 11 is re-adapted to the work platform 2. The dimensions of the lifting frame 112 in a first plane may be larger than the dimensions of other parts of the first arm 1111 to provide sufficient standing space for the worker to remain. For example, the lifting frame 112 may be a square in the first plane, with a side length approximately equal to the dimension of the auxiliary support 1A in the x-direction. The box-type telescopic boom 113 may move within the base 1121. By operating the box-type telescopic boom 113 to move within the base 1121, the length and / or position of the first arm 1111 in the x-direction can be adjusted.

[0135] The box-type telescopic boom 113 can vary its extension length through a multi-stage telescopic electric cylinder installed at the bottom. The telescopic boom adopts a box-type structure, which has high structural strength and rigidity, and can meet the requirements for personnel passage and material transportation.

[0136] In some embodiments, a ladder 115 may be provided on one side of the lifting frame 112 along the y-direction. When the lifting platform 11 is located at a preset position in the first tower section, the construction worker can reach the lifting frame 112 from the installation surface via the ladder 115.

[0137] In a specific implementation, continue to refer to Figures 4 to 6 The second arm 1112 can be a variable cross-section truss arm. The variable cross-section truss arm is hinged to the box-type telescopic arm 113, and the hinge axis is in the first plane. For example, the hinge axis of the variable cross-section truss arm and the box-type telescopic arm 113 can be parallel to the hinge axis of the lifting platform 11 and the lifting assembly 12.

[0138] Furthermore, the further away from the box-type telescopic boom 113, the smaller the cross-sectional area of ​​the variable cross-section truss arm. The three-dimensional dimension of the variable cross-section truss arm is largest at the end connected to the box-type telescopic boom 113, and decreases as it extends outward, thus extending from the box-type telescopic boom 113 in a trend of decreasing thickness. The variable cross-section truss arm is lightweight, reducing the overall weight of the lifting platform 11, especially the part suspended outside the auxiliary support 1A, which is smaller in both volume and weight, helping to reduce the risk of overturning of the auxiliary installation equipment 1. The variable cross-section truss arm has a large load-bearing capacity, which can meet the requirements of personnel passage and material transportation.

[0139] For example, the box-type telescopic boom 113 extends and retracts along the base 1121 on the lifting frame 112 via multi-stage electric actuators. A variable cross-section truss arm is hinged to the end of the box-type telescopic boom 113 furthest from the base 1121, forming an L-shaped variable radius platform structure. The radius refers to the distance relative to the auxiliary support 1A within the first plane. If the travel of the box-type telescopic boom 113 is insufficient, the extension section 114 connected to the end of the variable cross-section truss arm can be deployed to open a passage for workers to access the tower fixed platform 21.

[0140] In a specific implementation, refer to Figure 12 The lifting platform 11 may include a first arm 1111 extending in the y-direction from the auxiliary support 1A toward the lattice tower 3. Compared to Figures 4 to 11 In the illustrated embodiment, at least one arm 111 extends circumferentially along the lattice tower 3 in a first plane and at least partially surrounds the lattice tower 3 from the outside. In this embodiment, the first arm 1111 is erected between the auxiliary support 1A and the lattice tower 3 to form a connecting bridge.

[0141] Furthermore, each corner column 311 of the installed tower section of the lattice tower 3 is provided with a tower fixing platform 21, and a connecting platform 22 is provided between adjacent tower fixing platforms 21. The working platform 2 surrounds the lattice tower 3 in the first plane to form a closed structure.

[0142] Furthermore, the first arm 1111 can extend toward the tower fixing platform 21 or the communication platform 22. Figure 12 The example shown is the first arm 1111 extending from the auxiliary support 1A toward the nearest communication platform 22.

[0143] In some examples, the distance between the first arm 1111 and at least a portion of the working platform 2 of the installed tower segment in the first plane may be less than a preset value. For variable cross-section towers, the length or position of the first arm 1111 in the direction of extension toward the lattice tower 3 can be adjusted according to the cross-sectional dimensions of the tower segment 31 that needs to be adapted, so that the first arm 1111 is close to the working platform 2 of that tower segment 31. For example, as the lifting platform 11 rises, the extension length of the first arm 111 gradually increases to ensure that the distance to the working platform 2 of the tower segment 31 at the current height is less than a preset value.

[0144] In one variation, the end of the first arm 1111 facing the lattice tower 3 may be hinged to an extension section. The hinge axis may be parallel to the x-direction. For example, when the lattice tower 3 is erected to the top tower section, even if the first arm 1111 extends to its maximum length along the y-direction, it may not be able to reach the working platform 2 located on the penultimate tower section. In this case, the extension section can be deployed to indirectly extend the extension length of the first arm 1111.

[0145] exist Figure 12 In the embodiment shown, the specific structure of the lifting mechanism 1B and the first arm 1111 can be referred to the above reference. Figures 4 to 6 The description can also adopt any suitable technical solution in the existing technology, which will not be elaborated here.

[0146] In a specific implementation, continue to refer to Figure 1 The installation system described in this embodiment may further include a transverse connecting rod 13, connecting the auxiliary support 1A and the lattice tower 3. The auxiliary support 1A may have a reserved interface for transverse connection with the lattice tower 3. During the construction of the lattice tower 3, as the height of the installed tower section increases, the transverse stiffness of the auxiliary support 1A can be increased by setting the transverse connecting rod 13 between the auxiliary support 1A and the installed tower section. This is beneficial to improving the overall structural stability of the installation system. The setting of the transverse connecting rod 13 allows the auxiliary support 1A to be erected higher, enabling the lifting platform 11 to operate normally at a height of over 100 meters, assisting in the installation of high towers, and meeting the installation needs of lattice towers 3 over 100 meters.

[0147] In some embodiments, after the lattice tower 3 is installed, the tower fixing platform 21 can be retained on the corresponding corner posts 311 of each tower section 31. Thus, maintenance personnel can perform routine maintenance on the lattice tower 3 via the tower fixing platform 21, ensuring personnel safety during maintenance.

[0148] In some embodiments, the upper surface of the lifting platform 11 may be provided with an anti-slip surface to further improve the safety of personnel walking on it. For example, an anti-slip mat may be laid on the lifting platform 11.

[0149] Therefore, this implementation scheme designs an adjustable lifting platform 11 at a distance from the installed tower section, meeting the requirement that the cross-sectional dimensions of the variable cross-section tower change with height. Using this lifting platform 11 reduces the labor intensity of installation personnel climbing, minimizes safety risks during climbing, improves efficiency, and lowers installation costs.

[0150] Furthermore, the lifting platform 11 and the lifting assembly 12 are designed as separate units, connected by a hinge. This effectively prevents the stress deformation of the lifting platform 11 from being transmitted to the lifting assembly 12, ensuring the meshing state of the gears 1233 and racks 1234 of the lifting assembly 12, and improving the reliability and safety of the equipment.

[0151] While the above disclosure is provided, it is not limited thereto. Any person skilled in the art may make various alterations and modifications without departing from the spirit and scope of this disclosure; therefore, the scope of protection of this disclosure shall be determined by the scope defined in the claims.
