Description

Technical Field

[0001] This application relates to the field of wind power generation technology, and in particular to a tower installation device. Background Technology

[0002] Existing wind turbine generators and other tall mechanical structures typically include towers to support the nacelle, rotor, or other components at a predetermined height. These towers themselves are also usually quite tall. Towers are typically segmented along their height. Taking lattice or truss-type wind turbine towers as an example, the tower usually consists of 3-4 support columns and multiple diagonal braces between them, forming a triangular or quadrilateral structure. Each segment of a lattice-type tower is typically 10-15 meters high, and the segments are connected by flange bolts. Current installation methods involve using fixed work platforms on the support columns for workers to tighten the bolts during flange bolt installation. Workers climb ladders on the support columns to reach the fixed work platforms. This installation method is problematic because: firstly, it poses a significant safety risk to workers, especially with tall towers; secondly, it requires workers to move between different heights, resulting in low installation efficiency; and thirdly, if work needs to be done on other parts of the tower, workers must use slings to connect to the tower, further increasing safety risks.

[0003] Therefore, there is an urgent need for tower installation equipment that offers both high safety and high installation efficiency. Utility Model Content

[0033] The features and exemplary embodiments of various aspects of this application will now be described in detail. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain this application and are not configured to limit this application. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples of this application.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0035] It should be understood that when describing the structure of a component, when referring to a layer or region as being "above" or "on top of" another layer or region, it can mean that it is directly above the other layer or region, or that it contains other layers or regions between it and the other layer or region. Furthermore, if the component is flipped over, that layer or region will be located "below" or "under" the other layer or region.

[0036] It should be understood that although the terms "first" and "second" may be used to describe the form of the display device in the embodiments of this application, these forms should not be limited to these terms, which are only used to distinguish these forms from each other. For example, without departing from the scope of the embodiments of this application, the first form may also be referred to as the second form, and similarly, the second form may also be referred to as the first form.

[0037] The features and exemplary embodiments of various aspects of this application will now be described in detail. Furthermore, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0038] In existing wind turbine generator sets, the nacelle and rotor are typically supported by a tower or tower structure to maintain their position at a predetermined height. Because the tower is relatively long in the vertical direction, it is usually constructed using a multi-segment splicing structure. During tower installation, the first segment is connected to the supporting foundation, and then each segment is connected to the previous one until a complete tower is formed. This process requires operators to work at heights to manage the tower segments.

[0039] Based on this, the inventors discovered that existing work platforms, for example, are integrated at the connection points of tower sections. Operators need to climb up the tower to the work platform to perform their work. Moreover, due to the limited area of ​​the work platform, for work positions far from the work platform, operators need to connect to the tower via slings to perform their work, which results in relatively low safety and work efficiency.

[0040] To address the aforementioned technical problems, this application provides a tower installation device and a tower installation method, which can improve the safety and efficiency of the tower installation process.

[0041] It is understood that the following embodiments are only used as an example of applying the tower installation equipment to the installation of wind turbine towers. However, it should be understood that this application is not limited to this and can also be applied to other occasions where it is necessary to install support structures with large height dimensions that are spliced ​​from multiple sections, and to provide protection.

[0042] Furthermore, to better understand this application, the following will be combined with... Figures 1 to 7The tower installation equipment and tower installation method provided in the embodiments of this application will be described in detail.

[0043] Figure 1 This is a schematic diagram of the structure of a tower installation device provided in one embodiment of this application. Figure 2 yes Figure 1 An enlarged view of region P shown. Figure 3 This is a diagram showing the usage status of a tower installation device provided in one embodiment of this application.

[0044] According to an embodiment of this application, a tower installation device 100 is provided for installing a tower 200, the tower 200 including multiple tower segments. The tower installation device 100 includes: multiple auxiliary supports 20, at least partially extending along a first direction X and spaced apart from each other; and a lifting platform 30 movably connected to the multiple auxiliary supports 20. The lifting platform 30 and the auxiliary supports 20 are both arranged around the tower 200. The lifting platform 30 includes a working platform 32 for assembling tower segments and / or connecting adjacent tower segments, and the lifting platform 30 has a degree of freedom of movement relative to the auxiliary supports 20 along the first direction X, so that the working platform 32 can operate on different tower segments.

[0045] In this embodiment, an auxiliary support 20 independent of the tower 200 is provided, and a lifting platform 30 is provided on the auxiliary support 20 to drive the working platform 32 to be lifted and lowered. Therefore, construction personnel can change the construction position of the tower 200 with the help of the working platform 32 without having to climb it themselves, thereby improving construction safety and efficiency.

[0046] The tower 200 includes multiple tower segments arranged along a first direction. This application does not specifically limit the type of tower 200, which can be, for example... Figure 3 and Figure 5 The lattice tower shown means that each tower segment is lattice-shaped, that is, it is formed by assembling multiple rod-shaped components together; the tower 200 can also be a concrete tower, a steel tower, or a steel-concrete composite tower, etc.

[0047] Multiple auxiliary supports 20 can be spaced apart from each other, and both the auxiliary supports 20 and the lifting platform 30 are arranged around the tower 200. In one example, such as Figure 2 As shown, the lifting platform 30 can enclose a cavity 31 to accommodate the tower 200, and multiple auxiliary supports 20 can be arranged at circumferential intervals along the cavity 31. In another example, the lifting platform 30 may not have an enclosing closed structure, but may be configured to only partially surround the tower 200, for example, the lifting platform may be connected only on some adjacent auxiliary supports 20.

[0048] Each auxiliary support 20 can be a support frame with a certain cross-sectional area, such as, but not limited to, a lattice support frame. Alternatively, each auxiliary support 20 may include multiple sub-supports spaced apart from each other. This application does not impose any specific limitations on this, as long as it can be movably connected to the lifting platform 30 and has a structural strength exceeding a preset threshold.

[0049] The lifting platform 30 is movably connected to multiple auxiliary supports 20. Optionally, the lifting platform 30 can be connected to the outer side of the auxiliary supports 20 away from the tower 200, such that the orthographic projection of the lifting platform 30 along the first direction X surrounds the orthographic projection of the auxiliary supports 20 along the first direction X. For example, Figure 5 As shown, the lifting platform 30 may include a frame sleeved on the outside of each auxiliary support; or, the lifting platform 30 may be connected between adjacent auxiliary supports 20; or, the lifting platform 30 may be connected to the inside of the auxiliary support 20 facing the tower 200, and the orthographic projection of the auxiliary support 20 along the first direction X surrounds the orthographic projection of the lifting platform 30 along the first direction X.

[0050] It should be noted that although the accompanying drawings show that the tower installation equipment 100 includes four auxiliary supports 20 and the lifting platform 30 is connected to the auxiliary supports 20 and forms a quadrilateral, the embodiments of this application are not limited to this. The number of auxiliary supports 20 and the shape and structure of the lifting platform 30 can be flexibly set according to the shape and structure of the tower 200 to be installed.

[0051] Optionally, each auxiliary support 20 may have the same or similar structure and extend along the first direction X, that is, parallel to the extension direction of the tower 200 to be installed, so that the lifting platform 30 connected thereto is subjected to uniform force and the distance between the lifting platform 30 and the tower 200 remains uniform during the lifting process, reducing the possibility of collision damage between the lifting platform 30 and the tower 200. Furthermore, the multiple auxiliary supports 20 may be arranged at equal intervals around the circumference of the tower 200, thereby further improving the uniformity of force on the lifting platform 30 and enhancing the stability during the lifting process.

[0052] The lifting platform 30 includes a working platform 32, which is configured to extend at least partially toward the tower 200, for example, radially along the receiving cavity 31, to proximity to the tower 200. The lifting platform 30 may include multiple working platforms 32, which may be spaced apart on the lifting platform 30, for example, spaced apart circumferentially around the receiving cavity 31, to facilitate operation of the tower sections from various directions. Furthermore, the working platform 32 can be used to carry operators to operate on the corresponding tower sections, including operations requiring a certain height, such as assembling components to form tower sections or connecting adjacent tower sections; the working platform 32 may be equipped with safety railings.

[0053] The lifting platform 30 is movably connected to the auxiliary support 20, allowing the lifting platform 30 to move along the first direction X of the auxiliary support 20. This enables the lifting platform 30 to be positioned corresponding to different tower sections and different locations within each tower section, thus facilitating its raising as the height of the already erected portion of the tower 200 increases. Furthermore, the auxiliary support 20 can have the same or similar height as the tower 200 to be erected and can be erected before the tower 200.

[0054] It is understandable that the completion of the auxiliary support 20 before the tower base can mean that the auxiliary support 20 is first completely installed around the tower 200 to be installed. Alternatively, it can mean that the auxiliary support 20 and the tower 200 are installed and raised alternately, for example, a portion of the auxiliary support 20 is installed first, and then the portion of the tower 200 whose height does not exceed that portion of the auxiliary support 20 is installed.

[0055] By setting up multiple auxiliary supports 20 and enabling the lifting platform 30 to move freely up and down between the supports, the lifting platform 30 can be moved stably and conveniently to different height positions and to operate on different tower sections, thereby effectively improving the safety and operational efficiency during the installation of the tower 200.

[0056] In some alternative embodiments, the lifting platform 30 includes a lifting body 33 and a working platform 32. The lifting body 33 is movably connected to a plurality of auxiliary supports 20 and has a degree of freedom of movement along a first direction X. The lifting body 33 is arranged around the tower 200.

[0057] In some embodiments, such as, but not limited to, when the tower 200 has a constant cross-section, a portion of the lifting body 33 can be used as a work platform 32. By moving the lifting body 33 along the auxiliary support 20, the work platform 32 can perform operations on different tower sections, thereby improving safety and operational efficiency.

[0058] In some embodiments, such as, but not limited to, when the tower 200 has a different cross-sectional area (plane perpendicular to the first direction), the lifting platform 30 may include a lifting body 33 and a working platform 32. The lifting body 33 is movably connected to a plurality of auxiliary supports 20 and has a degree of freedom of movement along the first direction X. The lifting body 33 is arranged around the tower 200. The working platform 32 is connected to the lifting body 33 and is configured to extend at least partially toward the tower 200 and the distance between the working platform 32 and the tower 200 in a transverse plane perpendicular to the first direction is adjustable.

[0059] The lifting platform 30 in this embodiment may further include a lifting body 33 and a working platform 32. The lifting body 33 is movably connected to the auxiliary support 20 and arranged around the tower 200. In a non-limiting example, the lifting body 33 encloses a receiving cavity 31, that is, the lifting body 33 may be annular or connected between two auxiliary supports 20, surrounding the tower 200 to be installed. Optionally, the receiving cavity 31 formed by the lifting body 33 may have a shape adapted to the cross-section of the tower section. For example, in an embodiment where the cross-section of the tower 200 is rectangular, the receiving cavity 31 formed by the lifting body 33 may also be rectangular. As mentioned above, the lifting body 33 may also not have an enclosing closed structure, but may be configured to only partially surround the tower 200. For example, the lifting body 33 may only be connected to some adjacent auxiliary supports 20.

[0060] The working platform 32 is connected to the lifting body 33 and can move up and down together with the lifting body 33 along the auxiliary support 20. The working platform 32 and the lifting body 33 can be fixedly connected, detachably connected, or movably connected. In the embodiment where the two are movably connected, the working platform 32 can be moved relative to the lifting body 33 toward or away from the tower 200 to adjust the distance between the two and the tower 200. For example, but not limited to, the working platform 32 can move radially along the receiving cavity 31, or the working platform 32 can be moved along the lifting body 33 to change the operating position. In the embodiment where the two are fixedly connected or detachably connected, the size of the extension of the working platform 32 toward the tower 200 is adjustable to adjust the distance between the two and the tower 200. For example, but not limited to, the working platform 32 itself has an adjustable extension size radially along the receiving cavity 31.

[0061] Through the above two methods, the distance between the working platform 32 and the tower 200 to be installed in the transverse plane perpendicular to the first direction can be adjusted, which facilitates close-range operation by personnel and allows it to be adapted to tower sections with different diameters, thereby improving the practicality of the tower installation equipment 100.

[0062] In some alternative embodiments, the work platform 32 is movably connected to the lifting body 33 and is configured to move relative to the lifting body 33 toward or away from the tower 200 to adjust the distance between the work platform 32 and the tower 200; and / or, the size of the extension of the work platform 32 toward the tower 200 is adjustable to adjust the distance between the work platform 32 and the tower 200 in a transverse plane perpendicular to the first direction.

[0063] As previously mentioned, the distance between the working platform 32 and the tower section is adjustable, and can be further adjusted by moving and / or changing the size of the working platform 32.

[0064] Specifically, the work platform 32 can be movably connected to the lifting body 33. It is understood that this movable connection includes both translation and rotation. In embodiments where the work platform 32 can translate relative to the lifting body 33, the work platform 32 can move laterally to the extension direction of the lifting body 33, for example, it can have a movement trajectory extending at least partially radially along the receiving cavity 31, allowing the work platform 32 to move wholly or partially towards or away from the tower 200 through translation.

[0065] In an embodiment where the working platform 32 can rotate relative to the lifting body 33, the working platform 32 may be rotatably connected to the lifting body 33 at a position near one end, so that the working platform 32 can rotate toward the tower section, so that the opposite end approaches or moves away from the position of the tower section.

[0066] Alternatively, the working platform 32 itself may have an adjustable extension dimension in the direction transverse to the extension direction of the lifting body 33, such as an adjustable extension dimension in the radial direction of the receiving cavity 31. After being connected to the lifting body 33, it can adjust the distance between its end and the tower section by adjusting its own extension dimension.

[0067] In embodiments where the work platform 32 has a degree of freedom of movement relative to the lifting body 33 and is also capable of extension and retraction, the area of ​​the work platform 32 that can extend / retract can be staggered from the area connected to the lifting body 33 to reduce the possibility that the structure required for the movable connection will interfere with the extension and retraction of the work platform 32 itself.

[0068] In some alternative embodiments, the work platform 32 may be movable along the lifting body 33, and / or the work platform 32 may have rotational freedom relative to the lifting body 33 to operate at different locations on the tower section.

[0069] To further improve the practicality of the tower installation equipment 100, the working platform 32 may also be movable along the extension direction of the lifting body 33, for example, but not limited to, moving in the circumferential direction of the receiving cavity 31, so that the working platform 32 can be set relative to different positions on the outer periphery of the tower 200 in a transverse plane perpendicular to the first direction, thereby improving construction flexibility.

[0070] Optionally, in embodiments where the work platform 32 moves along the lifting body 33, the movement range of two adjacent work platforms 32 may partially overlap, be connected, or be staggered. For example, in embodiments where the work platform 32 does not interfere with the tower 200 and auxiliary support 20 during movement, the movement track of the work platform 32 may extend circumferentially along the receiving cavity 31 and be connected end-to-end in a ring shape, allowing each work platform 32 to move independently and freely to any position in the circumferential direction.

[0071] Alternatively, in embodiments where there is a possibility of interference between the working platform 32 and the auxiliary support 20, and / or the lifting body 33 is positioned between the auxiliary support 20, the moving tracks of each working platform 32 can be independently configured and designed according to the positions of the multiple auxiliary supports 20. For example, in embodiments where the cross-section of the tower 200 and the receiving cavity 31 are both quadrilateral, a working platform 32 can be provided at each of the four sides, and the moving range of the working platform 32 can be within the range of the corresponding side of the quadrilateral.

[0072] Optionally, the working platform 32 can also be rotatably connected to the lifting body 33 and can rotate relative to the lifting body 33 in a direction closer to or farther from the tower section to adjust the relative position and distance between the working platform 32 and the tower section, so that the working platform 32 can be set at different positions close to the tower section and adapt to tower sections of different sizes. At the same time, in the embodiment where the working platform 32 is rotatably connected to the lifting body 33, the working platform 32 can also be dimensionally adjustable in its own extension direction to avoid the tower section during rotation and facilitate rotation to a preset position for operation.

[0073] By configuring the work platform 32 to move along the extension direction of the lifting body 33 or to rotate relative to the lifting body 33, the relative position between the work platform 32 and the tower section can be easily adjusted, further improving the practicality of the work platform 32.

[0074] In some embodiments, the lifting platform 30 may include one or more working platforms 32. In embodiments containing only one working platform 32, the working platform 32 may be movable around the tower 200 along the lifting body 33, for example, but not limited to, circumferentially moving along the receiving cavity 31, to facilitate operation in various directions of the tower section. Simultaneously, the working platform 32 may have a certain width to provide operators with sufficient space to move around.

[0075] In some alternative embodiments, the lifting platform 30 includes a plurality of working platforms 32, each of which is configured to extend at least partially toward the tower 200 and is spaced apart around the tower 200 on the lifting body 33.

[0076] The lifting platform 30 in this embodiment includes a lifting body 33 and a working platform 32 connected to the lifting body 33. The lifting platform 30 may include multiple working platforms 32, which can be arranged at intervals around the tower 200 on the lifting body 33, i.e., at intervals along the circumference of the tower 200, to facilitate operation at various locations on the tower section. Alternatively, similar to the aforementioned embodiment with only one working platform 32, at least some of the multiple working platforms 32 can move circumferentially along the lifting body 33 to facilitate changing the construction position.

[0077] Optionally, each work platform 32 has the same or similar shape and size; each work platform 32 extends at least partially toward the tower 200 and the distance between it and the tower 200 is adjustable. By extending, for example, a portion of the work platform 32 extending radially along the receiving cavity 31 into the receiving cavity 31 and moving closer to the tower section, the distance between the work platform 32 and the tower section can be reduced, thereby allowing the personnel being carried to be closer to the tower section. By making the distance between it and the tower 200 adjustable, it can adapt to changes in the cross-sectional area of ​​the tower 200.

[0078] Optionally, the number and location of the working platforms 32 can be set according to the shape and size of the lifting body 33. For example, in an embodiment where the cross-section of both the receiving cavity 31 and the tower section is quadrilateral, more than one working platform 32 can be provided on each side of the quadrilateral to facilitate operation of the tower 200 from various directions.

[0079] In some alternative embodiments, the lifting platform 30 further includes a drive element 34 capable of driving relative movement between the work platform 32 and the lifting body 33, such as movement relative to the lifting body 33 toward or away from the tower 200, movement along the lifting body 33, rotation relative to the lifting body 33, etc. The drive element 34 includes at least one of a telescopic assembly, a hydraulic cylinder assembly, a pneumatic cylinder assembly, a gear and rack assembly, a sprocket and chain assembly, a worm gear assembly, a transmission belt assembly, or a slide rail and lead screw assembly.

[0080] In this embodiment, the lifting platform 30 and the auxiliary support 20 are movably connected, and the working platform 32 and the lifting body 33 are also movably connected. Therefore, the lifting platform 30 may include a driving component 34 for driving the relative movement between the working platform 32 and the lifting body 33.

[0081] Specifically, the drive component 34 may include a structure that drives the work platform 32 to move by its own telescopic movement, such as a telescopic assembly, a hydraulic cylinder assembly, or a pneumatic cylinder assembly. The telescopic assembly may be a scissor-type telescopic structure, a sliding rail telescopic structure, or a multi-link telescopic structure. Alternatively, the drive component 34 may also use other structural forms that drive linear movement by rotation, such as a gear and rack assembly, a sprocket and chain assembly, a worm gear assembly, a transmission belt assembly, or a sliding rail and lead screw assembly, and may use an electric motor as the power source.

[0082] By adopting the aforementioned drive structure, the movement of the work platform 32 can be made stable and controllable, further improving the reliability of the tower installation equipment 100.

[0083] In some alternative embodiments, the working platform 32 can be connected to the tower 200; and / or, the working platform 32 is spaced apart from the tower 200, and the tower installation equipment 100 further includes a stay cable connected between the lifting body 33 and the working platform 32 and / or connected between the auxiliary support 20 and the working platform 32.

[0084] To make the work platform 32 more stable and reliable during construction operations, the work platform 32 in this embodiment can be connected to the tower section, and / or the work platform 32 can be reinforced by means of stay cables.

[0085] Specifically, the extension of the work platform 32 toward the tower 200 can have a relatively long extension dimension, so that one end of the work platform 32 toward the tower 200 can be connected to the already installed part of the tower 200 structure. This part of the tower 200 structure supports the work platform 32, preventing the work platform 32 from forming a cantilever structure and improving its stability. When the lifting platform 30 needs to be raised or lowered, the position and / or extension dimension of the work platform 32 can be adjusted to move it to a position where it will not interfere with the tower 200 along the first direction X, and then the raising or lowering can be performed.

[0086] Alternatively, the work platform 21 can be reinforced with stay cables, which can be rigid or flexible. Connection points for connecting the stay cables can be provided on the lifting body 33 or the auxiliary support 20. These connection points can be located above or below the work platform 32 in the first direction X. The stay cables are connected between the connection points and the end of the work platform 32 facing the tower 200, providing support for the work platform 32 and further improving its stability. During lifting, the stay cables can be removed from the connection points, or the stay cables can be raised and lowered synchronously with the work platform 32.

[0087] In some alternative embodiments, the work platform 32 is connected to the tower 200 by means of overlapping, snap-fit, fastener connection or clamping connection.

[0088] In embodiments where the working platform 21 can be connected to the tower 200, the side of the working platform 32 closest to the tower 200 can be overlapped, snapped, fastened, or clamped to the tower 200. Specifically, a connection structure can be provided on the side of the working platform 32 facing the tower 200. This connection structure can be a snap-fit, a connection hole for fasteners to pass through, or a gripper, allowing the working platform 32 to form a detachable connection with the already erected portion of the tower 200 structure for temporary fixation. Correspondingly, before lifting or lowering, the connection between the working platform 32 and the tower 200 can be disconnected first, and the working platform 32 can be moved to a position along the first direction X where it does not interfere with the tower 200, before lifting or lowering.

[0089] In some alternative embodiments, the tower 200 includes a lattice tower 200, the tower section of the lattice tower 200 includes a plurality of corner posts 40 and support members 50 disposed between the plurality of corner posts 40, the working platform 32 is configured to be clamped and connected to the corner posts 40, and the working platform 32 is provided with a clamping part at one end facing the tower 200, the clamping part including a plurality of jaws rotatably connected to the end and a plurality of hydraulic cylinders connected between the end and the jaws.

[0090] The tower installation device 100 in this embodiment is used to install a tower 200 composed of multiple tower segments. The tower 200 can be a lattice tower 200. The lattice tower 200 includes multiple corner posts 40 located at the edge and support members 50 connected between the corner posts 40. The corner posts 40 and the support members 50 can both be cylindrical rods. The diameter of the corner posts 40 can be larger than the diameter of the support members 50 so that the corner posts 40 have good load-bearing capacity.

[0091] Based on this, the working platform 32 can be optionally configured to clamp and connect with the tower 200, and further optionally, the clamping portion at the end of the working platform 32 can be clamped and connected with the corner post 40 of the tower 200. Specifically, the working platform 32 extends at least partially toward the tower 200, and a clamping portion can be provided at the end extending toward the tower 200, which can be a plurality of grippers driven by a hydraulic cylinder.

[0092] Optionally, at least some of the multiple grippers are arranged symmetrically and can move in opposite directions by rotating with the end of the work platform 32 to clamp the corner post 40 therebetween. The inner side of the grippers, that is, the side facing the corner post 40, can be conformally arranged with the outer peripheral surface of the corner post 40 and can be provided with a buffer pad or other structure to increase friction and reduce the possibility of damage to the corner post 40.

[0093] The grippers can be driven by hydraulic cylinders to maintain a certain clamping force, ensuring a stable and reliable connection between the work platform 32 and the tower 200. The gripping unit may include multiple hydraulic cylinders that can drive the grippers to rotate. The hydraulic cylinders can be configured to correspond one-to-one with the grippers to allow for flexible movement and easy adjustment.

[0094] By setting up grippers and hydraulic cylinders, the working platform 32 and the tower 200 can be firmly connected through clamping, further improving the stability and reliability of the tower installation equipment 100.

[0095] In some optional embodiments, the tower installation equipment may further include a lifting assembly 10 for lifting tower sections and / or components thereof. The lifting assembly 10 is used to lift tower sections, their components, and equipment such as machinery required for installation that is inconvenient to carry manually, to a preset height. This preset height can be set according to the specific location where the lifted component needs to be used. For example, when lifting a tower section, it can be lifted to a height suitable for connection with the previous tower section.

[0096] In some examples, the lifting assembly 10 is mounted on at least one auxiliary support 20 and / or lifting platform 30. Optionally, the lifting assembly 10 in the embodiments of this application may include slings, hooks, lifting components similar to those of a tower crane, etc., and is used to lift tower sections, components constituting tower sections, and equipment required for installing tower sections. The lifting assembly 10 may be disposed on the top of the auxiliary support 20, or the lifting assembly 10 may be disposed on the lifting platform 30.

[0097] Specifically, the lifting assembly 10 can be installed on the top of the auxiliary support 20. During the raising of the auxiliary support 20, the lifting assembly 10 and the portion of the auxiliary support 20 on which the lifting assembly 10 is installed are raised together by means of a sleeve and a hydraulic jacking device. Alternatively, the lifting assembly 10 can be installed on the top of the auxiliary support 20 by a crane or other lifting equipment. In a plurality of auxiliary supports 20, at least some of the auxiliary supports 20 are provided with the lifting assembly 10, and optionally each auxiliary support is provided with the lifting assembly 10 to improve the flexibility of lifting.

[0098] Alternatively, the lifting assembly 10 can be installed on the lifting platform 30, or more preferably on the lifting body 33, and move together with the lifting platform 30 along the first direction X. In this embodiment, the number of lifting assemblies 10 can be one or more. When multiple lifting assemblies 10 are provided, each lifting assembly 10 can be arranged at intervals around the tower 200 to make the lifting platform 30 more evenly stressed.

[0099] Optionally, the tower installation equipment 100 may further include an auxiliary support structure 60 connected between the auxiliary supports 20. The auxiliary support structure 60 is used to improve the overall structural strength of the multiple auxiliary supports 20 and the stability of the relative positions between the multiple auxiliary supports 20. The auxiliary support structure 60 may be a rod-like member connected between adjacent auxiliary supports 20, and is arranged along the first direction X at least partially intersecting or spaced apart from each other, so that the structure of each part of the auxiliary support 20 is relatively stable.

[0100] It is understood that in embodiments where auxiliary support structures 60 are provided between auxiliary supports 20, the lifting body 33 can surround the auxiliary supports 20, or the lifting body 33 can be partially disposed between the auxiliary supports 20 and spaced apart from the auxiliary support structures 60. That is, if the lifting body 33 and the auxiliary support structures 60 are projected orthographically along the first direction X, their orthographic projections should be spaced apart to reduce the possibility of interference between them during lifting.

[0101] In some alternative embodiments, the lifting platform 30 includes multiple sub-platforms, each sub-platform being connected to two or more auxiliary supports 20 and capable of being lifted and lowered independently of each other.

[0102] The lifting platform 30 in this embodiment may include multiple independent sub-platforms, each sub-platform being connected to the auxiliary support 20. Each sub-platform may also be equipped with one or more working platforms 32 to facilitate operations on the tower section in various directions.

[0103] Optionally, each sub-platform can be movably connected to two or more auxiliary supports 20 simultaneously to improve the stability of the sub-platform. The connection method between the same sub-platform and each auxiliary support 20 can be the same to make its lifting and lowering smoother. Each sub-platform can be lifted and lowered independently, which facilitates the operator to work in different directions, positions, and even heights, further improving the flexibility of use.

[0104] In some alternative embodiments, at least one of the lifting platform 30, auxiliary support 20, and working platform 32 is formed as a lattice frame.

[0105] By setting the aforementioned three components as a lattice frame, it is possible to achieve good structural strength while maintaining a relatively light weight, and to easily adjust its size and extension direction by adding, removing, or connecting rods.

[0106] Understandably, in embodiments where the lifting platform 30 and the work platform 32 are lattice-frame structures, support plates can be mounted on them to facilitate standing and walking for operators. The support plates can be foldable or composed of multiple sub-plates for easy carrying.

[0107] Please refer to the following: Figures 4 to 6 , Figure 4 This is a schematic diagram of the structure of a tower installation device provided in another embodiment of this application. Figure 5 yes Figure 4 A magnified view of region Q shown. Figure 6 This is a diagram showing the usage status of a tower installation device provided in another embodiment of this application.

[0108] In some optional embodiments, the auxiliary support 20 is formed as a lattice frame; the lifting platform 30 or the specific lifting body 33 includes a lifting sleeve and a hydraulic jacking assembly. The lifting sleeve is sleeved on the outside of the auxiliary support 20 and is movably connected to the auxiliary support 20 along the first direction X. The lifting sleeve and the hydraulic jacking assembly are respectively provided with locking buckles that can be engaged with the auxiliary support 20. When the lifting platform 30 is raised or lowered, the lifting sleeve releases its engagement with the auxiliary support 20, and the hydraulic jacking assembly engages with the auxiliary support 20 to drive the lifting sleeve to rise or fall. Alternatively, the lifting platform 30 is provided with a lifting gear, and the auxiliary support 20 is provided with a lifting rack extending along the first direction X, with the lifting gear meshing with the lifting rack. Alternatively, the top of the auxiliary support 20 is provided with a lifting system, which is connected to the lifting platform 30 to drive the lifting platform 30 to move along the first direction X.

[0109] The auxiliary support 20 shown in the attached figure is a columnar structure, but the structure of the auxiliary support 20 is not limited to this. The auxiliary support 20 can be configured to be similar to... Figure 6 The middle tower 200 has a similar lattice structure. By setting the auxiliary supports 20 to a lattice structure, good structural strength can be maintained while reducing weight. The structures of each auxiliary support 20 can be identical to facilitate processing and assembly.

[0110] To enable the lifting platform 30 to move up and down along the first direction X, the lifting platform 30 or the lifting body 33 may include a lifting sleeve movably connected to the auxiliary support 20 and a hydraulic jacking assembly for driving the lifting sleeve to move relative to the auxiliary support 20 along the first direction X. The remaining parts of the lifting body 33 may be connected to the lifting sleeve to achieve lifting.

[0111] The lifting platform 30 may include multiple lifting sleeves 35, which are respectively fitted onto each auxiliary support 20 to achieve coordinated lifting or independent lifting. Furthermore, the lifting sleeves and the hydraulic lifting assembly may each be equipped with locking buckles, which are used to connect with the auxiliary support 20 and fix the relative position of the connected parts in the first direction X. When the lifting platform 30 is providing support and not lifting, the locking buckles on the lifting sleeves are locked to the auxiliary support 20 to ensure the height of the lifting platform 30 is stable and reliable.

[0112] When lifting is required, the locking buckle on the lifting frame can be disconnected from the auxiliary support 20, while the locking buckle on the hydraulic jacking assembly is connected and locked to the auxiliary support 20. At this time, one end of the hydraulic jacking assembly is connected to the auxiliary support 20 via the locking buckle, and the other end is connected to the lifting frame. The extension of the hydraulic jacking assembly in its extension direction pushes the lifting frame upwards along the auxiliary support 20. After the hydraulic jacking assembly extends to a certain size, the locking buckle on the lifting frame is then connected and locked to the auxiliary support 20 to control the retraction of the hydraulic jacking assembly. Repeating the above steps gradually raises the lifting frame to a preset height, ensuring smooth and reliable movement of the lifting platform 30 and enabling it to bear a large weight.

[0113] Alternatively, the lifting platform 30 or the specific lifting body 33 can also achieve lifting via a gear and rack combination. That is, a lifting rack extending along the first direction X can be provided on the auxiliary support 20, while a lifting gear and a drive structure for driving the lifting gear to rotate are provided on the lifting platform 30. Based on the meshing of the gear and rack, the rotation of the lifting gear enables the lifting gear and the lifting platform 30 to move along the lifting rack. Driving the movement of the lifting platform 30 via the gear and rack combination ensures stable movement of the lifting platform 30, providing good controllability and lower cost.

[0114] Alternatively, the top of the auxiliary support 20 may be equipped with a lifting system, such as, but not limited to, a hydraulic jack steel strand lifting system, a winch lifting system, etc. The lifting system connects to the lifting platform 30, specifically to the lifting body 33, to move the lifting platform 30 along the first direction X. Correspondingly, sliding rails and sliding components can be provided between the lifting body 33 and the auxiliary support 20 to ensure the stability and convenience of lifting.

[0115] Please see Figure 7 , Figure 7 This is a flowchart of a tower installation method provided in one embodiment of this application. According to an embodiment of this application, a tower installation method is proposed based on a tower installation device 100 according to any embodiment of the first aspect. The tower 200 includes multiple tower segments, including:

[0116] S1. Construct auxiliary supports 20 for tower installation equipment 100, such that the auxiliary supports 20 extend at least partially along the first direction X and are spaced apart from each other.

[0117] S2. Connect the lifting platform 30 of the tower installation equipment 100 to the auxiliary support 20, and enable the lifting platform 30 to move relative to the auxiliary support 20 in the first direction X.

[0118] S3, lifting tower section and / or components of the tower section;

[0119] S4. Control the lifting platform 30 to climb along the auxiliary support 20, and use the working platform 32 as an operating support to complete the construction of the tower section and / or the connection between adjacent tower sections.

[0120] This application also provides a tower installation method for tower installation equipment 100 applied to any of the embodiments of the first aspect, wherein at least the four steps S1 to S4 mentioned above are included.

[0121] Specifically, in step S1, auxiliary supports 20 are first erected. Multiple auxiliary supports 20 can extend parallel to each other and be spaced apart circumferentially on the tower section to be installed. The auxiliary supports 20 can be erected to the full height at once, or the auxiliary supports 20 can be gradually increased in height while maintaining a height higher than the point where the tower section is to be connected, so that the lifting platform 30 can be raised to the preset height.

[0122] In step S2, the lifting platform 30 is movably connected to the auxiliary support 20 erected in the previous step, ensuring that the lifting platform 30 can move up and down along the auxiliary support 20. Optionally, this may also include conducting pre-use tests on the load-bearing capacity and mobility of the lifting platform 30.

[0123] In step S3, the tower segment and / or its components are hoisted to a preset height using the hoisting assembly 10. Taking the tower segment as an example, the next tower segment can be hoisted to a position opposite to the previous tower segment, awaiting connection between the two.

[0124] In step S4, the lifting platform 30 is controlled to move along the auxiliary support 20 to a height corresponding to the position to be operated in the tower section, and is supported by the working platform 32 therein to complete the construction of the tower section or the connection between tower sections.

[0125] By alternating steps S4 (erecting and / or connecting the tower 200) with step S3 (raising the lifting platform 30), the tower 200 can be installed to the required height. This method allows for convenient and safe installation of the tower 200.

[0126] Optionally, the tower installation method may also include the step of adjusting the working platform 32, that is, adjusting the position of the working platform 32 on the lifting body 33 and the distance between the working platform 32 and the tower section, so that the working platform 32 can adapt to the changes in the diameter of the tower section at different heights and different operating positions for the same tower section. Specifically, the adjustment methods include telescopic, relative movement, and relative rotation.

[0127] Optionally, the tower installation equipment 100 may also include distance sensors and control components, so as to determine the position of the work platform 32 through the sensors and control the drive unit 34 through the control components to move the work platform 32 to a suitable position, thereby achieving a certain degree of automation and improving the accuracy and efficiency of control.

[0128] The tower installation method provided in this application has all the beneficial effects of the aforementioned tower installation equipment 100. For details, please refer to the specific descriptions of the tower installation equipment 100 in the above embodiments. This embodiment will not repeat them here.

[0129] It is understood that the above description and details are merely exemplary and explanatory, and do not constitute a limitation on this application. Those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Thus, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
