Description

Technical Field

[0001] This utility model belongs to the field of tower technology, and specifically relates to a structure for preventing deformation during tower manufacturing and transportation. Background Technology

[0002] In the wind power industry, segmented towers have been widely used. With the rapid development of the wind power industry, the diameter of segmented towers has reached a large size stage. Therefore, for ease of transportation, segmented towers are usually transported in multiple segments, which are then assembled on-site to form the final tower. However, severe deformation can occur during the manufacturing and transportation processes, making on-site assembly impossible and compromising safety if forced. Utility Model Content

[0003] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a structure that prevents deformation during tower manufacturing and transportation, which can effectively prevent deformation after cutting in the tower factory and during transportation, and also ensure the assembly efficiency of the tower during on-site assembly.

[0004] The technical solution adopted in this utility model is as follows: A structure for preventing deformation during tower manufacturing and transportation includes several segmented cylinders, which are assembled into a cylindrical body. Both ends of each segmented cylinder are fixed with segmented annular flanges along the axial direction. A circumferential anti-deformation fixture is connected between the two ends of the segmented annular flanges. Both ends of each segmented cylinder are connected with longitudinal flanges along the circumferential direction. Several longitudinal anti-deformation fixtures are connected between the longitudinal flanges at both ends of the segmented cylinder.

[0005] This invention relates to a cylindrical body divided into several segmented sections along its circumference. Each segmented section is secured by a circumferential anti-deformation fixture and several longitudinal anti-deformation fixtures. Therefore, when the cylindrical body is cut into segments, the segments are supported by these fixtures and will not deform. During transport, the segments are also supported at various points by the circumferential and longitudinal anti-deformation fixtures, ensuring that the segments will not deform during transport.

[0006] After transporting each segmented cylinder to the installation site, during on-site assembly, depending on the actual assembly situation, if it does not hinder assembly, the circumferential anti-deformation fixtures and several longitudinal anti-deformation fixtures can be left in place during assembly, and then removed after the pre-assembly fixtures are completed. Since the segmented cylinders are reliably supported by the circumferential and longitudinal anti-deformation fixtures during cutting and transportation, the segmented cylinders will not deform, thus improving the assembly efficiency.

[0007] As a preferred embodiment of this utility model, the longitudinal anti-deformation fixture includes a longitudinal anti-deformation fixture main beam, with longitudinal fitting fixture plates fixed at both ends of the main beam. The longitudinal fitting fixture plates are connected to longitudinal flanges. The longitudinal anti-deformation fixture main beam and the longitudinal fitting fixture plates can be welded together or forged as a whole. The longitudinal fitting fixture plates can be lengthened according to actual needs and equipped with multiple fixture holes.

[0008] As a preferred embodiment of this utility model, the longitudinal anti-deformation fixture main beam is perpendicular to the axis of the segmented cylinder, thereby improving the support effect on the segmented fixture.

[0009] As a preferred embodiment of this utility model, the longitudinal fitting tooling plate is connected to the longitudinal flange by process bolts or pins.

[0010] As a preferred embodiment of this utility model, the longitudinal bonding tooling plate is connected to the side of the longitudinal flange facing the inner cavity of the segmented cylinder, so as to avoid the longitudinal bonding tooling plate obstructing the cutting position of the adjacent segmented cylinder.

[0011] As a preferred embodiment of this utility model, the material of the longitudinal anti-deformation fixture main beam is H-beam, channel steel or thick steel plate, and the material of the longitudinally attached fixture plate is thickened steel plate.

[0012] As a preferred embodiment of this utility model, the cylindrical tower includes several cylindrical sections, which are sequentially welded into a cylindrical body along the axial direction. The cylindrical sections are formed by rolling and welding steel plates.

[0013] As a preferred embodiment of this utility model, the circumferential anti-deformation tooling is connected to the segmented circumferential flange by process bolts or pins.

[0014] As a preferred embodiment of this utility model, the material of the circumferential anti-deformation tooling is H-beam, channel steel or thick steel plate.

[0015] In a preferred embodiment of this invention, after several segmented cylindrical bodies are assembled and welded into a cylindrical body, a spacer is provided between adjacent longitudinal flanges of adjacent segmented cylindrical bodies. The spacer is connected to the two adjacent longitudinal flanges by bolts to prevent the spacer from falling off.

[0016] The beneficial effects of this utility model are as follows: 1. The cylindrical body of this utility model is divided into several segmented sections along its circumference. Each segmented section is fixed by a circumferential anti-deformation fixture and several longitudinal anti-deformation fixtures. Therefore, when the cylindrical body is cut into segments, the segments are supported by the circumferential and longitudinal anti-deformation fixtures and will not deform. During transportation, each segment is supported by the circumferential and longitudinal anti-deformation fixtures, ensuring that the segments will not deform during transport.

[0017] 2. Since the segmented cylinder is reliably supported by circumferential anti-deformation fixtures and several longitudinal anti-deformation fixtures during cutting and transportation, the segmented cylinder will not deform, which can correspondingly improve the assembly efficiency during current assembly.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other.

[0022] like Figures 1 to 7As shown, the structure for preventing deformation during tower manufacturing and transportation in this embodiment includes several segmented cylinders 1, which are assembled into a cylindrical body. Both ends of the segmented cylinder 1 along the axial direction are fixed with segmented annular flanges 2. A circumferential anti-deformation fixture 3 is connected between the two ends of the segmented annular flanges. A longitudinal flange 4 is connected to the inner side of both ends of the segmented cylinder 1 along the circumferential direction. Several longitudinal anti-deformation fixtures 5 are connected between the longitudinal flanges 4 at both ends of the segmented cylinder 1.

[0023] The cylindrical body of this invention is divided into several segmented cylindrical bodies 1 in the circumferential direction. Each segmented cylindrical body 1 is fixed by a circumferential anti-deformation fixture 3 and several longitudinal anti-deformation fixtures 5. Thus, when the segmented cylindrical bodies 1 are cut from the cylindrical body, the segmented cylindrical bodies 1 are supported by the circumferential anti-deformation fixtures 3 and several longitudinal anti-deformation fixtures 5 and will not deform. During the transportation of the segmented cylindrical bodies 1, each position of the segmented cylindrical bodies 1 is supported by the circumferential anti-deformation fixtures 3 and several longitudinal anti-deformation fixtures 5, so that the segmented cylindrical bodies 1 will not deform during transportation.

[0024] After transporting each segmented cylinder 1 to the installation site, during on-site assembly, depending on the actual assembly situation, if it does not hinder assembly, the circumferential anti-deformation fixture 3 and several longitudinal anti-deformation fixtures 5 can be left in place during assembly. These fixtures can be removed after the pre-assembly is complete. Because the segmented cylinder 1 is reliably supported by the circumferential anti-deformation fixture 3 and several longitudinal anti-deformation fixtures 5 during cutting and transportation, the segmented cylinder 1 will not deform, thus improving the assembly efficiency during current assembly processes.

[0025] Specifically, such as Figure 8 As shown, the longitudinal anti-deformation fixture 5 includes a longitudinal anti-deformation fixture main beam 51, with longitudinal fitting fixture plates 52 fixed at both ends of the longitudinal anti-deformation fixture main beam 51. The longitudinal fitting fixture plates 52 are connected to the longitudinal flange 4. The longitudinal anti-deformation fixture main beam 51 and the longitudinal fitting fixture plates 52 can be welded together or forged as a whole. The longitudinal fitting fixture plates 52 can be lengthened according to actual needs, and multiple fixture holes can be drilled.

[0026] The longitudinal anti-deformation fixture main beam 51 is perpendicular to the axis of the segmented cylinder 1, which improves the support effect on the segmented fixture.

[0027] The longitudinal fitting tooling plate 52 is connected to the longitudinal flange 4 by process bolts or pins.

[0028] The longitudinal bonding tooling plate 52 is connected to the side of the longitudinal flange 4 facing the inner cavity of the segmented cylinder 1, so as to avoid the longitudinal bonding tooling plate 52 blocking the cutting position of the adjacent segmented cylinder 1.

[0029] The longitudinal anti-deformation fixture main beam 51 is made of H-beams, channel steel, or thick steel plates, and the longitudinal fitting fixture plate 52 is made of thickened steel plates.

[0030] The cylindrical tower includes several cylindrical sections 6, which are sequentially welded into a cylindrical body along the axial direction. The cylindrical sections 6 are formed by rolling and welding steel plates.

[0031] The circumferential anti-deformation fixture 3 is connected to the segmented circumferential flange by process bolts or pins.

[0032] The material of the circumferential anti-deformation fixture 3 is H-beam, channel steel, or thick steel plate.

[0033] Furthermore, after several segmented cylindrical bodies 1 are bolted together to form a cylindrical body via adjacent longitudinal flanges, a spacer 7 is placed between adjacent longitudinal flanges 4 of adjacent segmented cylindrical bodies 1. The spacer 7 is bolted to the two adjacent longitudinal flanges 4 to prevent the spacer 7 from falling off.

[0034] Methods to prevent tower deformation during manufacturing and transportation include the following steps: S1: Roll and weld the steel plate into a cylindrical section 6; weld several cylindrical sections 6 sequentially along the axial direction to form a cylindrical body; divide the cylindrical body into several segmented cylindrical bodies 1 in the circumferential direction; S2: Segmented annular flanges 2 are fixed at both ends of segmented cylinder 1, and circumferential anti-deformation fixtures 3 are connected between the two ends of segmented circumferential flanges along the axial direction; longitudinal flanges 4 are connected to the inner side of both ends of segmented cylinder 1 along the circumferential direction, and several longitudinal anti-deformation fixtures 5 are connected between the longitudinal flanges 4 at both ends of segmented cylinder 1. S3: Cut the cylindrical body along the dividing line of the adjacent segmented cylindrical body 1; S4: Transport several segmented cylinders 1 to the installation site separately, and use bolts to assemble the several segmented cylinders 1 into a cylindrical body through adjacent longitudinal flanges 4; S5: A pad 7 is installed between adjacent longitudinal flanges 4 of adjacent segmented cylinder 1, and the pad 7 is connected to the two adjacent longitudinal flanges 4 by bolts.

[0035] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
