[0053] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0054] The development of power technology has accelerated the construction of wind and solar farms. The installation of towers is a crucial step in power plant construction, particularly for transmitting electricity. Currently, the most common method for tower installation is to hoist individual tower components separately, then assemble the components into a tower. To facilitate tower component installation, construction holes are typically provided in the components, and the location of these holes is crucial for both component installation and transportation.

[0055] In response to the above-mentioned problems, an embodiment of the present application provides a method for determining the position of a construction hole. The method determines the correspondence between the position of the construction hole and the bending moment of the tower component based on a pre-established mechanical model of the tower component for the target tower component; determines the allowable stress of the construction hole at different positions based on the pre-acquired tower component parameters and the correspondence; and determines the target position of the construction hole based on the allowable stress of the construction hole at different positions and the transportation and assembly constraints. In the technical solution of the embodiment of the present application, taking into account the structure of the tower component itself, the stress conditions, and the transportation and assembly constraints, a more appropriate position of the construction hole can be determined, thereby making the tower component more convenient to transport and assemble, and improving the safety of the tower component during transportation and assembly.

[0056] The method for determining the location of the construction hole provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. The application environment may include a terminal 102 and a server 104, and the terminal 102 communicates with the server 104 through a network. The data storage system can store data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. The terminal 102 can obtain various parameters of the tower component and the transportation assembly constraints, wherein the tower component parameters may include the length, mass, density of the material, etc. of the tower component; the terminal 102 transmits the tower component parameters and the transportation assembly constraints to the server 104, and the server 104 can determine the target position of the construction hole based on the tower component parameters and the transportation assembly constraints. In some embodiments, the server 104 can also obtain the tower component parameters and the transportation assembly constraints from the data storage system, which is not limited in the embodiment of the present application and can be set according to actual conditions.

[0057] The terminal 102 may be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, etc. The server 104 may be implemented as an independent server or a server cluster consisting of multiple servers.

[0058] In an exemplary embodiment, Figure 2 As shown, a method for determining the location of a construction hole is provided, and the method is applied to Figure 1 The following steps are used as an example to illustrate the server in the example:

[0059] Step 201 : For a target tower component, determine the corresponding relationship between the position of the construction hole and the tower component bending moment according to a pre-established tower component mechanical model.

[0060] Tower components specifically refer to the various parts of a tower, primarily including the following: 1) Main members: These are the main supporting members of the tower, bearing the majority of the load and forming the backbone of the tower structure. 2) Diagonal members: These connect the main members, enhancing the tower's stability and rigidity, and are typically arranged diagonally. 3) Cross members: These are members arranged crosswise between the main members, further strengthening the tower's integrity and torsional resistance. 4) Horizontal members: These are members installed horizontally on the tower, providing connection and support, and helping to improve the tower's lateral stability. 5) Auxiliary members: These are auxiliary members used to connect and secure other main components, ensuring a tight connection between the tower's sections. 6) Connecting plates: These are metal plates used to connect different components, joining them together through bolts or welding. 7) Tower foot plates: Located at the base of the tower, they connect to the foundation, transferring the tower's loads to the foundation and ensuring its stability. 8) Attachment plates: These are plates used to mount attachment points such as insulator strings and are key components connecting the tower to the conductors. 9) Foot Spikes: These spike-shaped components facilitate climbing the tower, typically located along the main structure. 10) Ladders: These ladders allow workers to ascend and descend the tower, facilitating maintenance and inspection. These components, through rational segmentation and joint design, form the tower's overall structure, ensuring safety and reliability under various operating conditions.

[0061] When using these tower components to construct a tower, the components often need to be hoisted to a predetermined height, and then assembled into a tower using multiple components. The construction holes are used to hoist the target tower component. During the hoisting process, a hoisting rope is passed through the construction holes, and the hoisting equipment pulls the rope to hoist the target tower component.

[0062] For different tower components, the server can pre-establish their corresponding tower component mechanical models. In this way, when determining the position of the construction holes, the server can analyze the influence of the construction holes at different positions on the tower component bending moment based on the tower component mechanical model of the target tower component, thereby determining the corresponding relationship between the position of the construction holes and the tower component bending moment.

[0063] Taking the target tower as a beam-type structure tower as an example, the principle of bending moment equilibrium in material mechanics can be used to analyze and calculate the bending moment distribution of the target tower under the action of its own weight. Assuming that the tower is a uniform rod, the gravity per unit length is q = ρgA, where ρ is the material density; g is the acceleration of gravity, which can be taken as 9.81m / s2; and A is the cross-sectional area of ​​the target tower, which can be calculated based on the cross-sectional shape of the target tower. The construction hole is at a distance x from one end of the tower. The position of the construction hole and the tower bending moment M(x) can be expressed as formula (1):

[0064] When 0≤x≤L / 2,

[0065] When L / 2<x≤L, -----------------(1)

[0066] Wherein, L is the length of the target tower, and q is the weight per unit length of the target tower.

[0067] Step 202: Determine the allowable stresses of the construction holes at different positions based on the tower component parameters and corresponding relationships obtained in advance.

[0068] Tower component parameters include dimensions such as length, width, radius, and arc length, as well as at least one of cross-sectional shape, mass, and material density. Allowable stress refers to the stress allowed for a part or component in mechanical or engineering structural design. There is a mapping relationship between allowable stress and tower component bending moment.

[0069] The server can pre-acquire tower component parameters from a terminal, input by staff, or from a database. When determining the location of construction holes, the pre-acquired tower component parameters are substituted into the aforementioned correspondence to determine the tower component bending moments corresponding to the construction holes at different locations. A mapping relationship exists between tower component bending moments and allowable stresses. Based on this mapping relationship and the tower component bending moments corresponding to the construction holes at different locations, the allowable stresses at the construction holes at different locations can be calculated.

[0070] For example, the mapping relationship is σ = k * M (x), where σ is the allowable stress, k is the mapping coefficient, and M (x) is the tower bending moment at the construction hole at a distance x from one end of the tower. When x = a, substituting a into the above relationship can calculate the tower bending moment Ma. Based on the mapping relationship, the mapping coefficient, and the tower bending moment a, the allowable stress σa of the construction hole at a distance from the tower end can be calculated. When x = b, substituting b into the above relationship can calculate the tower bending moment Mb. Then, based on the mapping relationship, the mapping coefficient, and the tower bending moment b, the allowable stress σb of the construction hole at a distance b from the tower end can be calculated. Similarly, the allowable stress corresponding to the construction hole at different locations can be calculated.

[0071] Step 203 : determining the target position of the construction hole according to the allowable stress of the construction hole at different positions and the transport assembly restriction conditions.

[0072] Among them, the transportation and assembly restrictions include the conditions that need to be met for the location of construction holes when transporting tower components and assembling the iron tower using tower components.

[0073] The tower structure has an inherent structure with a range of allowable stresses. Based on this range and the different allowable stresses corresponding to different construction hole locations, the location range of the construction holes can be preliminarily determined. Any location within this range that meets the transport and assembly constraints can be selected as the target location for the construction hole.

[0074] In the above embodiment, for the target tower component, the correspondence between the position of the construction hole and the tower component bending moment is determined based on a pre-established mechanical model of the tower component; the allowable stress of the construction hole at different positions is determined based on the pre-acquired tower component parameters and the correspondence; and the target position of the construction hole is determined based on the allowable stress of the construction hole at different positions and the transportation and assembly constraints. In the technical solution of the embodiment of the present application, taking into account the structure of the tower component itself, the stress conditions, and the transportation and assembly constraints, a more appropriate position of the construction hole can be determined, thereby making the tower component more convenient to transport and assemble, and improving the safety of the tower component during transportation and assembly.

[0075] In an exemplary embodiment, Figure 3 As shown, in the above embodiment, “determining the allowable stresses of the construction holes at different positions based on the pre-acquired tower component parameters and corresponding relationships” may include the following steps:

[0076] Step 301: Calculate the section modulus of the target tower component according to tower component parameters.

[0077] The section modulus is a mechanical property of a component's cross-section that is related to its shape and size. It indicates the section's ability to resist bending during bending deformation and is an important indicator of a component's load-bearing capacity. The section modulus can be calculated based on the cross-sectional shape and size. For example, the section modulus for a circular cross-section is W = πr³ / 4, where r is the radius of the circle; and the section modulus for a square cross-section is W = a³ / 6, where a is the side length of the square.

[0078] Tower component parameters include cross-sectional shape, length, width, radius, and other dimensions. The server calculates the section modulus of the target tower component based on the cross-sectional shape, length, width, and other dimensions.

[0079] Step 302: Calculate the tower bending moments of the construction holes at different positions based on the corresponding relationship.

[0080] The tower component parameters also include the material density and length of the tower component.

[0081] Based on the material density ρ of the tower component, the gravitational acceleration g, and the cross-sectional area A of the target tower component, the unit length gravity q can be calculated. Substituting the unit length gravity q, the length L of the tower component, and the position x of the construction hole into the corresponding relationship in formula (1), the tower component bending moment M(x) at different positions x of the construction hole can be calculated.

[0082] Step 303 : Calculate the allowable stress of the construction holes at different positions based on the tower member bending moments and section moduli at different positions of the construction holes.

[0083] The mapping relationship between the tower component bending moment and the allowable stress is σ(x)=M(x) / W, where σ(x) is the allowable stress of the construction holes at different positions, M(x) is the tower component bending moment at different positions of the construction holes, and W is the section modulus of the target tower component.

[0084] The ratio between the bending moment and the section modulus of the tower component at different locations of the construction holes is calculated to obtain the allowable stress at different locations of the construction holes.

[0085] In the above embodiment, the section modulus of the target tower member is calculated based on the tower member parameters; the tower member bending moment at different locations of the construction holes is calculated based on the corresponding relationship; and the allowable stress of the construction holes at different locations is calculated based on the tower member bending moment and section modulus at different locations. In calculating the allowable stress, the embodiment of the present application fully considers the ability of the tower member cross section to resist bending, which can make the allowable stress more accurate and, in turn, the location of the construction holes more appropriate.

[0086] In an exemplary embodiment, Figure 4 As shown, in the above embodiment, "determining the target position of the construction hole according to the allowable stress of the construction hole at different positions and the transportation assembly restriction conditions" may include the following steps:

[0087] Step 401 : determining the initial position range of the construction hole according to the allowable stress and preset stress range corresponding to the construction hole at different positions.

[0088] The preset stress range may include the minimum allowable stress and the maximum allowable stress that the tower component can withstand.

[0089] After calculating the allowable stresses corresponding to the construction holes at different positions, the positions corresponding to the allowable stresses within the preset stress range can be determined, and the initial position range of the construction holes can be determined based on these positions.

[0090] For example, the preset stress range is [σ1, σ2], the allowable stress corresponding to the construction hole at a distance of m from one end of the tower member is σ1, and the allowable stress corresponding to the construction hole at a distance of n from one end of the tower member is σ2. Then the initial position range of the construction hole is between m and n from one end of the tower member.

[0091] Step 402: Determine the target location of the construction hole from the initial location range according to the transportation assembly constraint conditions.

[0092] A position is selected from the initial position range. If the position satisfies the transport assembly constraint condition, the position can be determined as the target position of the construction hole. If the position does not satisfy the transport assembly constraint condition, the position is not the target position of the construction hole.

[0093] It is understandable that there may be multiple target locations for the construction holes.

[0094] In some embodiments, a position with the minimum allowable stress is selected from the initial position range, and if the position meets the transportation assembly restriction condition, the position is determined as the target position of the construction hole.

[0095] In the above-described embodiment, the initial position range of the construction holes is determined based on the allowable stresses and preset stress ranges corresponding to the construction holes at different positions; and the target position of the construction holes is determined from within the initial position range based on the transportation and assembly constraints. The present embodiment fully considers the constraints imposed on the position of the construction holes by transportation and assembly, making the final position of the construction holes more convenient for the transportation and assembly of the tower components and improving the safety of the tower components during transportation and assembly.

[0096] In an exemplary embodiment, Figure 5 As shown, the transport and assembly constraints include transport constraints and hoisting constraints. In the above embodiment, "determining the target position of the construction hole from the initial position range according to the transport and assembly constraints" may include the following steps:

[0097] Step 501 : for any candidate position within the initial position range, determine the first segment length and the second segment length from the candidate position to both ends of the target tower, and the target distance between the candidate position and the center of gravity of the target tower.

[0098] Assume that the target tower is a uniform rod-shaped tower with a length of L. For any candidate position x within the initial position range, the rod-shaped tower is divided into two segments with the candidate position as the dividing point. The length from the candidate position to one end of the tower is the first segment length x, and the length from the candidate position to the other end of the tower is the second segment length Lx.

[0099] For tower components with regular shapes and uniform mass distribution, the center of gravity (xg) can be determined based on the component's shape. However, for tower components with complex shapes or uneven mass distribution, specialized measurement tools and calculation methods are required to accurately determine the center of gravity. The target distance |xd - xg| between the center of gravity and the candidate locations can then be calculated.

[0100] Step 502: When the first segment length and the second segment length meet the transportation restriction condition and the target distance meets the lifting restriction condition, the candidate position is determined as the target position of the construction hole.

[0101] If the first segment length x and the second segment length Lx satisfy the transportation restriction condition, and the target distance |xd-xg| also satisfies the lifting restriction condition, the candidate position x can be determined as the target position of the construction hole.

[0102] If the first segment length x and the second segment length Lx do not satisfy the transportation restriction condition, and / or the target distance |xd-xg| does not satisfy the lifting restriction condition, a new candidate position is selected from the initial position range.

[0103] In the above embodiment, for any candidate position within the initial position range, a first segment length and a second segment length from the candidate position to both ends of the target tower member, as well as a target distance between the candidate position and the center of gravity of the target tower member, are determined; if the first segment length and the second segment length satisfy the transportation restriction conditions, and the target distance satisfies the hoisting restriction conditions, the candidate position is determined as the target position of the construction hole. In the embodiment of the present application, the position of the construction hole satisfies both the transportation restriction conditions and the hoisting restriction conditions, making the position of the construction hole convenient for both transportation and hoisting.

[0104] In an exemplary embodiment, the transport constraint condition includes that the first segment length and the second segment length are both less than or equal to the tool length of the transport tool. The lifting constraint condition includes that the target distance is less than or equal to the lifting radius of the lifting equipment.

[0105] For transportation constraints, assume the transport vehicle is a transport vehicle with a length Lt and width Wt. If the tower component needs to be placed horizontally during transportation, ensure that the length of the tower component segments with construction holes does not exceed the length of the transport vehicle's compartment. That is, for x within the initial position range [x1, x2], the first segment length x ≤ Lt and the second segment length Lx ≤ Lt must be satisfied. This ensures that the tower component fits the dimensions of the transport vehicle and can be transported smoothly.

[0106] For assembly constraints, the stability of the tower component during lifting and the capacity of the lifting equipment are taken into consideration. Suitable hole locations are further selected based on the positional relationship between the construction hole and the tower component's center of gravity, as well as the lifting radius. For example, given the lifting height Ht and lifting radius Rt of the lifting equipment, if the construction hole is xd from one end of the tower component and the tower component's center of gravity is xg, |xd - xg| ≤ Rt must be satisfied. Understandably, if the distance between the construction hole and the tower component's center of gravity is too large, exceeding the lifting radius limit, the tower component could easily shake, tilt, or even fall during lifting, potentially damaging the component or causing a safety accident. By limiting the distance between the two within the lifting radius, the lifting operation can be carried out safely and smoothly, while also matching the lifting capacity of the lifting equipment and ensuring a smooth lifting operation.

[0107] At the same time, the location selection of construction holes also needs to comprehensively consider factors such as the structural strength of the tower components, the connection method of the lifting equipment, and the on-site working environment to ensure that the lifting operation can be carried out safely and efficiently under the condition of |xd-xg|≤Rt.

[0108] The embodiment of the present application imposes restrictions on transportation and hoisting respectively, which can not only improve the safety of the tower component during transportation, but also improve the safety of the tower component during hoisting.

[0109] In an exemplary embodiment, Figure 6 As shown, the embodiment of the present application may further include the following steps:

[0110] Step 601: Determine the stress-bearing parts of the target tower component and the maximum allowable stress of the stress-bearing parts according to the structure of the target tower component and the actual installation method.

[0111] The actual installation method includes the relationship between the conductor, the pulley, and the construction hole. The pulley is an important lifting and transportation tool, which can include pulleys, shafts, frames or hangers, slings, etc.

[0112] The following takes different actual installation methods as an example to analyze the stress-bearing parts of the target tower and the maximum allowable stress at the stress-bearing parts.

[0113] Reference Figure 7a A diagram of a conductor passing through a pulley construction hole shows a rectangular structure, which may represent a portion of a tower. Crossing lines within the rectangle indicate the tower's structure. The diagram also shows the location of a construction hole and a conductor leading from it, with a downward force G acting on the conductor.

[0114] Reference Figure 7b The diagram shows the process of laying out the conductor through the pulley. The conductor is led out from the construction hole on the tower and passes through the pulley. The conductor is subject to tension T and gravity G. The relationship between some angles and forces is marked in the diagram, such as T 张 cos20°, etc., is used to illustrate the decomposition of the force applied by the wire through the pulley during the wire-laying process.

[0115] Reference Figure 7b The figure is also a schematic diagram of the conductor passing through the pulley to tighten the line (operating tower), showing the situation during the tightening operation. Formula (2) expresses the tension Tz at the construction hole and the line tension T anchor and the conductor weight G 导 And the additional force N 附加 The relationship between:

[0116] -----------(2)

[0117] Through this diagram and formula, the tension on the construction hole during the tightening operation can be calculated, providing a basis for construction design and safety assessment.

[0118] Reference Figure 7cThis figure shows the hole for the conductor anchor. The rectangle in the figure represents the part of the tower with cross lines inside. The figure shows the location of the hole for the conductor anchor. A conductor is led out of the hole. The conductor has tension T and gravity G. The anchor tension T is also marked in the figure. 锚 Tension T at the construction hole 张 Relationship T 张 =T 锚 / 6. This diagram illustrates the tension of the conductor passing through the construction hole during anchor line construction, and its relationship to the tension of the anchor line, helping construction personnel understand the transmission and distribution of force.

[0119] The tension calculation of the hoisting construction hole in the middle of the tower is as shown in formula (3), and the tension calculation of the hoisting construction holes on both sides of the tower is as shown in formula (4):

[0120] ---------------------------------(3)

[0121] ----------------------------------(4)

[0122] Among them, G 极 represents the gravity of the polar line, α is the coefficient, N 附加 These formulas are used to calculate the tension that construction holes in different locations will bear during the construction process, providing an important theoretical basis for construction design and safety assurance.

[0123] Referring to the above analysis method, determine the stress-bearing parts of the target tower component and the maximum allowable stress (unit: Pascal) of the stress-bearing parts according to the structure of the target tower component and the actual installation method.

[0130] Step 2: Calculate the section modulus of the target tower component based on the tower component parameters; calculate the tower component bending moment at different positions of the construction holes based on the corresponding relationship; and calculate the allowable stress of the construction holes at different positions based on the tower component bending moment and section modulus at different positions of the construction holes.

[0131] Step 3: Determine the stress-bearing parts of the target tower component and the maximum allowable stress of the stress-bearing parts according to the structure of the target tower component and the actual installation method; and determine the preset stress range according to the maximum allowable stress.

[0132] Step 4: Determine the initial position range of the construction holes according to the allowable stress and preset stress range corresponding to the construction holes at different positions.

[0133] Step 5: for any candidate position within the initial position range, determine the first segment length and the second segment length from the candidate position to the two ends of the target tower, and the target distance between the candidate position and the center of gravity of the target tower;

[0134] Step 6: When the first segment length and the second segment length meet the transportation restriction condition and the target distance meets the lifting restriction condition, the candidate position is determined as the target position of the construction hole.

[0135] Among them, the transportation restriction conditions include that the length of the first segment and the length of the second segment are both less than or equal to the tool length of the transportation tool; the lifting restriction conditions include that the target distance is less than or equal to the lifting radius of the lifting equipment.
