Description

Technical Field

[0001] This application relates to the field of tower installation, and particularly to a method for installing tower sections. Background Art

[0002] As an important part of clean energy, wind power has developed rapidly globally in recent years. As an important support structure for wind turbines, the installation quality and efficiency of wind power towers are directly related to the operational stability and economic benefits of wind power projects. With the continuous progress of wind power technology, the requirements for tower installation technology are also getting higher and higher. Especially in the installation of tall, large and complex tower structures, how to improve construction efficiency, reduce costs and ensure installation accuracy has become the focus of industry attention.

[0003] In the traditional installation process of wind power towers, methods such as ground assembly and overall hoisting, sectional hoisting, etc. are usually adopted. These methods mainly include using large lifting equipment for overall hoisting, or completing splicing on-site after sectional hoisting. In addition, there are also some methods that combine auxiliary support structures and temporary fixing devices to improve the stability of the installation process. However, these traditional methods often seem inadequate when facing tall towers, especially in installation operations in complex environments, where the construction difficulty and safety risks increase significantly.

[0004] Although these conventional means in the prior art can meet the requirements of tower installation to a certain extent, in the installation process of tall towers, there are still problems such as long construction period, high cost and difficult to guarantee installation accuracy. Especially when the tower height increases, how to hoist the tower on the offshore foundation platform and how to ensure installation efficiency, stability and accuracy during the installation process have become technical problems to be solved urgently. Summary of the Invention

[0005] In order to facilitate improving the installation efficiency, stability and accuracy of the tower on the offshore foundation platform, this application provides a method for installing tower sections.

[0006] A method for installing tower sections provided by this application adopts the following technical solutions: A method for installing tower sections includes the following steps: S1: Establishment of temporary lifting equipment: Install a winch on the foundation platform; S2: Establishment of a tower hoisting system: Lift the main body of the gin pole to the foundation platform, and install an upper pulley assembly at the top of the main body of the gin pole, and form a tower hoisting system around the main body of the gin pole, the upper pulley assembly and the winch; S3: Lifting the components to be installed: Use the tower crane lifting system to lift multiple components to be installed onto the foundation platform one by one and complete the installation operation of the lifting objects. The components to be installed include the main legs of the tower crane on the first floor and the corresponding bases of the main legs of the tower crane. S4: Hoist boom lifting: Set up an internal hoist boom pulling system between multiple main legs of the tower crane and the main body of the hoist boom. Set up a hoist boom lifting system on the inner side of the main legs of the tower crane and at the bottom of the main body of the hoist boom. Use the hoist boom lifting system to lift the main body of the hoist boom upward to a predetermined height, and install a support system at the bottom of the main body of the hoist boom to support the suspended main body of the hoist boom. During the lifting process of the main body of the hoist boom, the internal hoist boom pulling system pulls the main body of the hoist boom to maintain the vertical state of the main body of the hoist boom. S5: Hoisting of tower crane loose parts: Use a winch in cooperation with an upper pulley assembly to hoist the tower crane loose parts between adjacent main legs of the tower crane in sequence. S6: Repeat the hoist boom lifting step and the lifting step of the components to be installed to complete the upward continuous connection operation of the main legs of the tower crane and the installation of the remaining tower crane loose parts until the tower crane installation construction is completed. When performing the hoist boom lifting step, adjust the position of the internal hoist boom pulling system upward according to the position of the hoist boom.

[0007] By adopting the above technical solutions, a temporary lifting equipment and a tower crane lifting system are established, providing a stable and reliable support structure for subsequent lifting operations, ensuring the safety and reliability of the entire installation process. During the process of lifting the components to be installed, use the tower crane lifting system to complete the hoisting and installation of multiple main legs and bases of the tower crane in sequence, significantly improving the construction efficiency and reducing the construction period. The application of the hoist boom lifting system enables the main body of the hoist boom to be gradually lifted to a predetermined height as the height of the tower crane increases, avoiding the problem of frequent replacement or adjustment of equipment in the traditional method, reducing the construction difficulty and cost. The setting of the internal hoist boom pulling system effectively ensures the vertical state of the main body of the hoist boom during the lifting process, preventing potential safety hazards caused by inclination, and improving the installation accuracy at the same time. The implementation of the hoisting step of the tower crane loose parts further improves the overall structure of the tower crane, ensures the coordinated cooperation between components, and enhances the stability and durability of the tower crane. By repeating the hoist boom lifting and the lifting step of the components to be installed, the continuous upward connection of the main legs of the tower crane and the installation of the remaining tower crane loose parts are realized, and finally the installation construction of the entire tower crane is completed, demonstrating the high efficiency and practicality of this method.

[0008] Preferably, the main body of the hoist boom includes a number of hoist boom units spliced in sequence. In S2, use a winch to lift each hoist boom unit to the foundation platform one by one.

[0009] By adopting the above technical solutions, the sectional splicing and hoisting of the mast body are realized, effectively reducing the weight and difficulty of single hoisting. Specifically, the mast body is decomposed into several mast units, and each unit is hoisted to the foundation platform one by one by a winch, making the hoisting process safer and more controllable. At the same time, the dependence on large lifting equipment is reduced, and the construction flexibility and efficiency are improved. In addition, the sectional splicing method is also convenient for transportation and assembly, further reducing the construction cost.

[0010] Preferably, when hoisting the mast unit, a guiding pulley is first installed at the corner position of the foundation platform. The towing rope of the winch passes through the guiding pulley and then connects to the mast unit to be hoisted. The mast unit to be hoisted is connected to the guy wire. Under the traction of the winch, the guiding of the guiding pulley, and the adjustment and control of the guy wire, the mast unit is stably hoisted onto the foundation platform.

[0011] By adopting the above technical solutions, the mast unit can ensure its stability and accuracy during hoisting with the help of the guiding of the guiding pulley and the adjustment and control of the guy wire. Specifically, the setting of the guiding pulley effectively reduces the friction between the towing rope and the foundation platform, improving the hoisting efficiency; the adjustment and control of the guy wire can correct the attitude of the mast unit in real time during hoisting, avoiding tilting or swinging, thus ensuring that the mast unit is hoisted onto the foundation platform safely and smoothly.

[0012] Preferably, in the step S3, the bottom of one of the mast units is hinged to the foundation platform and the upper pulley assembly is installed at the top of the mast unit. The mast unit is tilted to a preset angle by a chain block. The towing rope of the winch passes through the upper pulley assembly and then connects to the component to be installed. The component to be installed is connected to the guy wire. By retracting the towing rope of the winch and monitoring and adjusting the guy wire, the component to be installed is hoisted onto the foundation platform.

[0013] By adopting the above technical solutions, hinging the bottom of the mast unit to the foundation platform and adjusting the tilt angle with a chain block ensure the stability of the mast unit during hoisting and reduce the operation risk. Using the upper pulley assembly to guide the towing rope of the winch, combined with the monitoring and adjustment of the guy wire, effectively controls the attitude of the component to be installed in the air, improving the hoisting accuracy and safety. The whole process is simple and efficient, reducing the labor and time costs and improving the construction efficiency.

[0014] Preferably, the upper pulley assembly includes a fixed rod and a first fixed pulley installed at the end of the fixed rod. Before the mast lifting step of the step S4, the splicing step of the mast body is carried out first, and the steps are as follows: First, splice a part of the mast units within the allowable width range of the foundation platform as the foundation of the mast body; Then install the fixing rod on the top of the foundation of the pole body, with the end of the fixing rod protruding from the top of the foundation of the pole body; Then pass the towing rope of the winch through the first fixed pulley and connect it to one of the remaining pole units, and use a chain block to erect the foundation of the pole body; Next, with the cooperation of the winch and the first fixed pulley, lift the pole unit above the foundation of the pole body, and then vertically join the pole unit above the foundation of the pole body to serve as a new foundation for the pole body; Next, disassemble the fixing rod and install it on the top of the new foundation of the pole body; Then connect the towing rope of the winch to one of the remaining pole units, and then lift and assemble the new foundation of the pole body according to the above steps until the pole body is completely joined.

[0015] By adopting the above technical solution, first assemble a part of the pole units as the foundation within the allowable range of the width of the foundation platform, which effectively reduces the weight and difficulty of single lifting, reduces the construction risk, and can complete the joining of the pole body within the limited space of the foundation platform. Even if the pole is long, it can be assembled orderly, effectively solving the assembly problem caused by space limitation. In addition, by using the cooperation of the fixing rod and the first fixed pulley, the lifting path of the pole unit is optimized, the lifting efficiency is improved, and the balance of the pole unit during the lifting process is ensured. After each section of the pole unit is joined, the fixing rod is disassembled and reinstalled on the new top in time, ensuring the smooth progress of subsequent lifting operations and avoiding the interference of the fixing rod on the lifting process of the pole body. By repeating the above steps until the pole body is completely joined, the gradual extension and precise docking of the pole body are realized, ensuring the stability and reliability of the overall structure.

[0016] Preferably, the pole lifting system includes a winch, a lower pulley assembly installed at the bottom of the pole body, a side pulley assembly symmetrically installed inside two of the main legs of the tower, and a towing connection member. When performing the pole lifting step in S4, the towing rope of the winch passes through the side pulley assembly and the lower pulley assembly in sequence and then connects to the towing connection member, and the pole body is lifted upward and to a predetermined height by the way of the winch winding the towing rope.

[0017] By adopting the above technical solution, the cooperation of the winch with the lower pulley assembly, the side pulley assembly and the towing connection member enables the pole body to be precisely controlled and gradually lifted to a predetermined height. This design not only ensures the stability of the pole body during the lifting process, but also effectively reduces the possible shaking and deviation during the construction process, thereby improving the construction efficiency and safety. In addition, this solution optimizes the force transmission method by reasonably planning the path of the towing rope, reduces the wear degree of the equipment, and prolongs the service life of the equipment.

[0018] Preferably, when performing the hoisting step of the tower component of S5, a supporting system is constructed between the main body of the gin pole and the main leg of the tower. The towing rope of the winch is disconnected from the towing connection member and the side pulley assembly of the tower main body, and the towing rope of the winch passes through the lower pulley assembly and the upper pulley assembly in sequence and then is connected to the tower component to be hoisted.

[0019] By adopting the above technical solution, constructing the supporting system can effectively support the main body of the gin pole, ensure its stability during the hoisting process of the tower components, and reduce the risk of shaking or tilting caused by external forces; after the towing rope of the winch is disconnected from the original connection structure and re-arranged, the towing rope passes through the lower pulley assembly and the upper pulley assembly in sequence, and finally the towing rope is connected to the tower component to be hoisted, optimizing the force path, improving the hoisting efficiency, achieving precise hoisting, simplifying the operation process, and enhancing the construction safety and reliability.

[0020] Preferably, the internal pulling system of the gin pole includes a plurality of chain blocks. The plurality of chain blocks are respectively connected to a plurality of tower main legs, and the pulling ends of the plurality of chain blocks are connected to the periphery of the main body of the gin pole; during the gin pole lifting step of S4, the plurality of chain blocks simultaneously adjust the pulling length to cooperate with the gin pole lifting action, and the pulling lengths of the plurality of chain blocks are kept consistent to keep the gin pole in a vertical state during the lifting process; during the tower component installation step of S5, by simultaneously adjusting the pulling lengths of the plurality of chain blocks, the pulling lengths of the plurality of chain blocks are different, so that the top of the main body of the gin pole tilts upward above the tower component installation position for the installation of the tower component.

[0021] By adopting the above technical solution, the internal pulling system of the gin pole is composed of a plurality of chain blocks, and the chain blocks are respectively connected between the tower main legs and the main body of the gin pole. During the lifting process of the gin pole, by simultaneously adjusting the pulling lengths of the chain blocks and keeping them consistent, the vertical state of the main body of the gin pole during the lifting process can be effectively ensured, thereby improving the stability and safety of the installation process. During the tower component installation step, by differentially adjusting the pulling lengths of the chain blocks, the top of the main body of the gin pole can be tilted above the tower component installation position, providing convenience for the installation of the components, and further improving the installation efficiency and accuracy.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. By means of the step-by-step gin pole lifting and tower component hoisting, the installation problem of the high-rise tower in a limited space is effectively solved, and the construction efficiency is significantly improved and the installation cost is reduced; 2. The synergistic effect of the internal pulling system of the gin pole and the chain blocks ensures the vertical state of the main body of the gin pole during the lifting process, and improves the stability and accuracy of the installation process; 3. The reasonable design of the tower crane system, combined with the application of the winch and pulley assembly, realizes the precise hoisting and docking of the components to be installed, further ensuring the installation quality.

Detailed Description of the Embodiment

[0028] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 drawings.

[0029] An embodiment of the present application discloses a tower section installation method, including the following steps: S1: Establishment of temporary hoisting equipment: Referring to Figure 1 , specifically, the temporary hoisting equipment uses a winch 4. The installation position and method of the winch 4 need to be adjusted according to the specific structure of the foundation platform 1. For example, it is fixed on the preset anchor bolts by bolts, or fixed on the foundation platform 1 by welding. After installation, it is necessary to check the stability of the winch 4 to ensure that it can withstand the tension during subsequent hoisting. The transport ship 3 transports the component to be installed 14 and the lifting pole unit 51 to one side of the foundation platform 1 and waits for hoisting.

[0030] S2: Establishment of the tower hoisting system: Referring to Figure 2 and Figure 3, establish the tower crane system, which includes lifting the main body 5 of the gin pole to the foundation platform 1, and installing an upper pulley assembly 6 at the top of the main body 5 of the gin pole, and forming a tower crane system around the main body 5 of the gin pole, the upper pulley assembly 6 and the winch 4.

[0031] Specifically, the main body 5 of the gin pole is composed of a number of gin pole units 51 spliced in sequence, and these gin pole units 51 can be spliced by means of flange connection or bolt connection, etc. The upper pulley assembly 6 includes a fixed rod and a first pulley installed at the top of the fixed rod.

[0032] When lifting the gin pole units 51 to the foundation platform 1 one by one, first install a guiding pulley 2 at the corner position of the foundation platform 1. The towing rope 41 of the winch 4 passes through the guiding pulley 2 and is connected to the gin pole unit 51 to be lifted. The gin pole unit 51 to be lifted is connected to the guy wire 7. Under the traction of the winch 4, the guiding of the guiding pulley 2 and the adjustment and control of the guy wire 7, the gin pole unit 51 is stably lifted to the foundation platform 1.

[0033] The installation position of the pulley assembly needs to be accurately measured to ensure that it is aligned with the axis of the main body 5 of the gin pole to avoid deviation during the lifting process. The connection method between the pulley assembly and the main body 5 of the gin pole can be welding or connection through fasteners, and the specific choice depends on the material and structure of the main body 5 of the gin pole.

[0034] S3: Lift the component 14 to be installed: Lifting the component 14 to be installed includes using the tower crane system to lift a plurality of components 14 to be installed to the foundation platform 1 in sequence and complete the installation operation of the hoisting object. Among them, the component 14 to be installed includes the main tower legs 10 on the first floor and the corresponding bases of the main tower legs 10.

[0035] Before lifting the component 14 to be installed, first hinge the bottom of one of the gin pole units 51 to the foundation platform 1 and install the fixed rod of the upper pulley assembly 6 at the top of one side of the gin pole unit 51. Use a chain block to tilt the gin pole unit 51 to a preset angle so that the first pulley is directly above the installation position of the component to be lifted. A connecting flange is arranged below the installation position of the component to be lifted for connecting with the component to be lifted. The towing rope 41 of the winch 4 passes through the upper pulley assembly 6 and is connected to the component 14 to be installed. The component 14 to be installed is connected to the guy wire 7. By retracting the towing rope 41 of the winch 4 and monitoring and adjusting the guy wire 7, and the guy wire 7 is also pulled by the winch 4, the component 14 to be installed is accurately hoisted to the connecting flange on the foundation platform 1 and installed and fixed. Then re-hinge and install the gin pole unit 51 at the next installation point to facilitate the accurate hoisting steps of the next component to be lifted. Repeat the above steps until the installation of the bases and the corresponding tower main bodies at the four corner positions on the foundation platform 1 is completed.

[0036] After the installation of the main legs 10 of the first - layer tower is completed, the splicing step of the main body 5 of the gin pole is carried out. In this embodiment, the length of each gin - pole unit 51 is 3m, and the whole main body 5 of the gin pole consists of five gin - pole units 51, with a total length of 15m. Due to the limited width space of the foundation platform 1, it is impossible to directly erect the whole main body 5 of the gin pole. Therefore, the following splicing steps are adopted: a: First, splice a part of the gin - pole units 51 within the allowable width range of the foundation platform 1 as the foundation of the main body 5 of the gin pole. In this embodiment, three gin - pole units 51 are spliced first.

[0037] b: Then install the fixing rod on the top of the foundation of the main body 5 of the gin pole. The end of the fixing rod protrudes from the top of the foundation of the main body 5 of the gin pole, and the protruding length is in the range of 1.5m - 2m.

[0038] c: Then pass the towing rope 41 of the winch 4 through the first fixed pulley and connect it to one of the remaining gin - pole units 51. The connection point is at the center - of - gravity position of the gin - pole unit 51, that is, at half of the length of the gin - pole unit 51. Then use a chain block to erect the foundation of the main body 5 of the gin pole to the vertical state and use the inclined - support method for temporary support and stabilization.

[0039] d: Then, with the cooperation of the winch 4 and the first fixed pulley, lift the gin - pole unit 51 to be connected above the foundation of the main body 5 of the gin pole, and then vertically splice the gin - pole unit 51 above the foundation of the main body 5 of the gin pole and use it as the new foundation of the main body 5 of the gin pole.

[0040] e: Then reinstall the position of the upper - pulley assembly 6, that is, disassemble the fixing rod and install it on the top of the new foundation of the main body 5 of the gin pole, and the end of the fixing rod protrudes from the top of the foundation of the main body 5 of the gin pole, and the protruding length is in the range of 1.5m - 2m.

[0041] f: Then connect the towing rope 41 of the winch 4 to one of the remaining gin - pole units 51, and then lift and assemble the new foundation of the main body 5 of the gin pole with the gin - pole unit 51 according to the above steps until the splicing of the main body 5 of the gin pole is completed.

[0042] S4: Gin - pole lifting: The form of the gin pole lifting includes forming a gin pole internal pulling system 8 between multiple tower main legs 10 and the gin pole main body 5, forming a gin pole lifting system inside the tower main legs 10 and at the bottom of the gin pole main body 5, using the gin pole lifting system to lift the gin pole main body 5 upward to a predetermined height, and installing a supporting system 9 at the bottom of the gin pole main body 5 to support the suspended gin pole main body 5. The gin pole internal pulling system 8 includes a number of chain hoists, which are connected to several tower main legs 10 one by one, and the pulling ends are connected to the circumferential side of the gin pole main body 5. The selection of the chain hoist needs to be based on the actual pulling force requirements, and the installation position of the chain hoist needs to be adjusted according to the position of the tower main legs 10 to ensure that it can be evenly stressed. During the lifting process of the gin pole, the chain hoists simultaneously adjust the pulling length to cooperate with the gin pole lifting action, and the pulling lengths are kept consistent to maintain the vertical state of the gin pole during the lifting process.

[0043] Among them, the gin pole lifting system includes a winch 4, a lower pulley assembly 52 installed at the bottom of the gin pole main body 5, side pulley assemblies 12 symmetrically installed inside two of the tower main legs 10, and a traction connection member. It should be emphasized that in order to reduce the influence of the traction rope 41 on the normal lifting of the gin pole main body 5, a limit pulley 13 is installed at the bottom of one of the tower main legs 10 far from the winch 4. When performing the gin pole lifting step of S4, the traction rope 41 of the winch 4 passes through the limit pulley 13, the side pulley assembly, and the lower pulley assembly 52 in sequence and then connects with the traction connection member, and the gin pole main body 5 is lifted upward to a predetermined height by winding the traction rope 41 of the winch 4. Then, a supporting system 9 is constructed between the gin pole main body 5 and the tower main legs 10. The supporting system 9 is several inclined steel wire rope stays. The inclined upper ends of the several steel wire rope stays are connected to several tower main legs 10 one by one, and the inclined lower ends are connected to the bottom of the gin pole main body 5. It plays a supporting role.

[0044] Then, the traction rope 41 of the winch 4 is disconnected from the traction connection member of the tower main body and the side pulley assembly 12, and the traction rope 41 of the winch 4 passes through the limit pulley 13, the lower pulley assembly 52, and the upper pulley assembly 6 in sequence and then connects with the tower loose parts 11 to be hoisted.

[0045] S5: Hoisting of tower loose parts 11: Refer to Figure 3 and Figure 4 , the hoisting of the tower loose parts 11 includes using the winch 4 to cooperate with the upper pulley assembly 6 to hoist the tower loose parts 11 between adjacent tower main legs 10 in sequence. When performing the hoisting step of the tower loose parts 11, check whether the supporting system 9 constructed between the gin pole main body 5 and the tower main legs 10 is stable enough.

[0046] In the installation steps of the tower components 11, first, by simultaneously adjusting the pulling lengths of several chain hoists, at this time, the pulling lengths of several chain hoists are different, making the top of the mast body 5 tilt directly above the installation position of the tower components 11, so as to accurately install the tower components 11. During the hoisting process, it is necessary to monitor and adjust the guy ropes 7 to ensure that the tower components 11 remain balanced and stable in the air.

[0047] S6: Repeat the mast lifting step and the hoisting step of the component to be installed 14 to complete the upward continuation operation of the tower main legs 10 and the installation of the remaining tower components 11 until the tower installation construction is completed; when performing the mast lifting step, adjust the position of the internal guy system 8 of the mast upward according to the position of the mast.

[0048] It should be noted that when performing the mast lifting step, it is necessary to adjust the position of the internal guy system 8 of the mast upward according to the position of the mast. When adjusting the position of the internal guy system 8 of the mast, since the pulling effect of the internal guy system 8 on the mast body 5 will fail for a short time, it is necessary to temporarily add lateral guy ropes between the mast body 5 and multiple tower main legs 10 to maintain the temporary stability of the mast body 5.

[0049] The implementation principle of this embodiment is: By establishing a temporary hoisting device and a tower hoisting system, the efficient hoisting and installation of the tower sections are realized. The use of the internal guy system 8 and the mast lifting system ensures the stability and safety of the mast body 5 during the lifting process. Through a reasonable construction plan and operation process, the continuous, rapid and precise installation steps of multiple tower sections can be completed at the limited space of the foundation platform 1. At the same time, these plans and processes can also reduce waste and repetitive labor during the construction process, improve construction efficiency and quality. By reducing the installation time and cost, improving construction efficiency and quality, the construction cost and maintenance cost of the entire wind power project can be reduced. In addition, this method can also improve the stability and durability of the wind power tower, extend its service life, reduce the failure rate and maintenance cost.

[0050] In other embodiments, to improve the stability of the mast body 5 during lifting, and The above are all preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
