Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to a maintenance tool for hybrid towers. Background Technology

[0002] In the construction of wind turbine concrete-steel hybrid towers (referred to as "hybrid towers"), the steel-concrete conversion section, i.e., the converter, is usually installed first, followed by the continuous hoisting of concrete tower sections upwards. During this continuous high-altitude construction, the epoxy resin structural adhesive used for bonding the upper concrete tower sections inevitably drips or flows, directly contaminating the surface of the already installed converter below. When the dripped structural adhesive hardens, it forms a hard, potentially sharp-edged, residue. During the subsequent operation of the hybrid tower, this hardened adhesive will continuously contact, rub against, and even impact the prestressing cables. In severe cases, the sharp edges can wear down or even cut the prestressing cables. This damage not only seriously threatens the overall structural safety of the hybrid tower and significantly weakens the design performance and service life of the prestressing cables, but also greatly increases the high-cost, high-risk maintenance burden in the later stages, ultimately jeopardizing the long-term safe and stable operation and power generation efficiency of the wind turbine generator.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The following is combined Figure 1 This invention describes a maintenance fixture for a mixing tower provided in an embodiment of the present invention. It should be understood that the following description is merely an illustrative embodiment of the present invention and does not constitute any particular limitation on the present invention.

[0025] An embodiment of this utility model provides a maintenance fixture for a mixing tower, such as... Figure 1 As shown, it includes: a separation component 200, which is connected to the prestressed cable 300 of the mixing tower; and a drive mechanism 400, which is connected to the separation component 200 and is used to drive the separation component 200 to move the prestressed cable 300 in a direction away from the converter 100 of the mixing tower.

[0026] The maintenance fixture for hybrid power towers provided by this utility model includes a separation component 200 and a drive mechanism 400. The separation component 200 is connected to the prestressed cable 300 of the hybrid power tower, and the drive mechanism 400 is connected to the separation component 200. The drive mechanism 400 can drive the separation component 200 to move the prestressed cable 300 along a direction away from the converter 100 of the hybrid power tower. Based on this maintenance fixture for hybrid power towers, maintenance of the hybrid power tower can be performed. Specifically, by driving the separation component 200 through the drive mechanism 400 to move the prestressed cable 300 along a direction away from the converter 100 of the hybrid power tower, a certain distance is separated between the prestressed cable 300 and the converter 100. This facilitates the cleaning of epoxy resin structural adhesive on the surface of the converter 100 by personnel, avoids frictional damage to the prestressed cable 300 caused by the hardened adhesive, effectively protects the prestressed cable 300, extends its service life, reduces the high-cost and high-risk maintenance burden in the later stages, ensures the structural safety and operational safety of the hybrid power tower, and guarantees the power generation efficiency of the hybrid power tower.

[0027] In one embodiment of the present invention, the separation component 200 includes: a separation frame, which encloses the prestressed cable 300; and a drive mechanism 400 connected to the separation frame and used to drive the separation frame to move the prestressed cable 300 along the direction away from the converter 100 of the mixing tower.

[0028] For example, the prestressed cable 300 is installed vertically and can pass through one side of the separation frame to the other. The drive mechanism 400 is connected to the separation frame and can drive the separation frame to move horizontally, causing the separation frame to move the prestressed cable 300 closer to or away from the converter 100. When maintenance is required, the drive mechanism 400 moves the separation frame away from the converter 100, creating a distance between the converter 100 and the prestressed cable 300, allowing workers to clean the hardened adhesive on the converter 100 and to perform maintenance on the surrounding components of the converter 100. After maintenance is completed, the drive mechanism 400 moves the separation frame closer to the converter 100, and then the maintenance fixture for the mixing tower is disassembled. By using the separation frame to enclose the prestressed cable 300, the weight of the entire maintenance fixture for the mixing tower can be reduced.

[0029] In one embodiment of this utility model, the separation frame includes: a first crossbeam 210; a second crossbeam 220, the second crossbeam 220 being spaced apart from the first crossbeam 210; a first connecting column 230, the first connecting column 230 being connected between the first crossbeam 210 and the second crossbeam 220; and a second connecting column 240, the second connecting column 240 being connected between the first crossbeam 210 and the second crossbeam 220, and the second connecting column 240 being spaced apart from the first connecting column 230.

[0030] A frame area is formed between the first crossbeam 210, the second crossbeam 220, the first connecting column 230 and the second connecting column 240, and the frame area is used to frame the prestressed cable 300.

[0031] Furthermore, in one embodiment of this utility model, the first crossbeam 210 and the second crossbeam 220 are parallel to each other; the first connecting column 230 and the second connecting column 240 are parallel to each other; and the first crossbeam 210 and the first connecting column 230 are perpendicular to each other.

[0032] like Figure 1 As shown, in this embodiment, the first crossbeam 210 and the second crossbeam 220 are spaced apart and parallel to each other, and the first connecting column 230 and the second connecting column 240 are spaced apart and parallel to each other. The first connecting column 230 and the second connecting column 240 are respectively vertically connected to the two ends between the first crossbeam 210 and the second crossbeam 220. The first crossbeam 210, the second crossbeam 220, the first connecting column 230, and the second connecting column 240 together form a square frame structure, and the prestressed cable 300 passes through one side of the square frame structure to the other side. The driving mechanism 400 is connected to the square frame structure and can drive the frame structure to move the prestressed cable 300 closer to or away from the converter 100.

[0033] In one embodiment of this utility model, both the first crossbeam 210 and the second crossbeam 220 are telescopic crossbeam structures; both the first connecting column 230 and the second connecting column 240 are telescopic connecting column structures. Therefore, by adjusting the telescopic lengths of the first crossbeam 210, and / or the second crossbeam 220, and / or the first connecting column 230, and / or the second connecting column 240, the frame area of ​​the separation frame can be changed, thereby improving the versatility of the maintenance tooling for the mixing tower.

[0034] In one embodiment of the present invention, the first crossbeam 210 includes: a crossbeam body 211, one end of which is connected to one end of a second crossbeam 220 via a first connecting post 230, and the other end of which is connected to the other end of the second crossbeam 220 via a second connecting post 240; an extension connecting section 212, which is connected to the end of the crossbeam body 211; and a drive mechanism 400, one end of which is connected to the segments of the mixing tower, and the other end of which is connected to the extension connecting section 212.

[0035] In one embodiment of the present invention, the driving mechanism 400 includes a jack 410, one end of which is connected to the pipe segment of the mixing tower, and the other end of which is connected to the extension connecting section 212.

[0036] Furthermore, in one embodiment of this utility model, the extended connecting section 212 includes: a first extended section connected to one end of the crossbeam body 211; a second extended section connected to the other end of the crossbeam body 211; and a jack 410 is provided between the first extended section and the pipe segment of the mixing tower, and between the second extended section and the pipe segment of the mixing tower.

[0037] For example, such as Figure 1 As shown, the first crossbeam 210 is located on the side away from the converter 100, and the second crossbeam 220 is located on the side closer to the crossbeam. The crossbeam body 211 and the second crossbeam 220 are parallel to each other, have the same length, and are aligned at both ends. A first extension section and a second extension section are respectively provided at both ends of the crossbeam body 211. A jack 410 is installed between the first extension section and the mixing tower segment, and another jack 410 is installed between the second extension section and the mixing tower segment. Anti-slip pads made of high-friction rubber are installed between the jacks 410 and the mixing tower segments to ensure the stability of the mixing tower during top drive.

[0038] For example, the first crossbeam 210 and the second crossbeam 220 are high-strength square steel pipes made of Q235 steel. Their length can be determined according to the size of the converter 100 and the maintenance and operation space requirements, and is generally taken as 0.5m. The first connecting column 230 and the second connecting column 240 are made of Q235 angle steel, and their specifications can be determined according to the lifting force of the jack 410 and the overall stability of the tooling. The height of the first connecting column 230 and the second connecting column 240 is designed according to the height of the mixing tower and the maintenance and operation space requirements, and is generally 0.5m, to ensure that the tooling equipment can meet the maintenance requirements of mixing towers of different heights.

[0039] In one embodiment of the present invention, the maintenance fixture for the mixing tower further includes a pressure detection device, which is connected to the jack 410 and is used to detect the top driving pressure of the jack 410.

[0040] In another embodiment of the present invention, the maintenance fixture for the mixing tower further includes: a displacement detection device, which is connected to the jack 410 and is used to detect the top drive displacement of the jack 410.

[0041] Therefore, during the jacking process of jack 410, the jacking pressure and displacement of jack 410 can be accurately displayed, which can ensure that the jacking process is stable and accurate, and meet the maintenance needs of the mixing tower components under different working conditions.

[0042] During installation, firstly, based on the actual installation location and site conditions of the prestressed cable tower, the second crossbeam 220 is placed on the back of the prestressed cable 300. The first connecting column 230 and the second connecting column 240 are then bolted to both ends of the second crossbeam 220. The first crossbeam 210 is then placed on the front of the prestressed cable 300 and bolted to the first connecting column 230 and the second connecting column 240. A jack 410 is then connected between the first crossbeam 210 and the segments of the prestressed cable tower. Anti-slip pads are placed between the jack 410 and the segments to ensure that the jack 410 does not slip during the lifting process.

[0043] During maintenance, when the mixing tower needs maintenance, the control system of jack 410 is activated. Jack 410 slowly and steadily lifts the first crossbeam 210, thereby separating the prestressed cable 300 from the converter 100 by a certain distance. This distance is determined according to the actual maintenance needs to provide sufficient operating space for maintenance personnel to inspect and maintain the converter 100 and surrounding components. During the lifting process, the values ​​of the pressure detection device and displacement detection device are closely monitored. At the same time, tools such as a level can be used to monitor the verticality and horizontality of the mixing tower. If any abnormalities occur, such as sudden pressure changes, displacement deviations exceeding the allowable range, or tilting of the mixing tower, the lifting operation should be stopped immediately. A comprehensive inspection of the tooling equipment and the mixing tower should be carried out. The cause should be analyzed and appropriate adjustments made before the lifting operation can continue.

[0044] After the top drive is in place, for the epoxy resin that has dripped onto the converter 100, the appropriate cleaning tools and methods can be selected according to the state of the epoxy resin. If the epoxy resin has not completely hardened, it can be carefully scraped off with a scraper or other tools; if the epoxy resin has hardened, it can be softened by heating equipment (such as a hot air gun) before cleaning, or a special epoxy resin solvent can be used to dissolve and clean it. During the cleaning process, care should be taken to avoid damaging the converter 100 and the prestressed cable 300.

[0045] In addition, a comprehensive inspection of the converter 100 and surrounding components can be conducted to check for damage or wear caused by epoxy resin dripping or other reasons. If any problems are found, they should be repaired or replaced promptly. For example, if scratches or damage are found on the surface of the converter 100, it can be repaired by grinding or replaced with a new converter 100, depending on the extent of the damage. For the prestressed cable 300, its surface should be carefully inspected for damage or broken wires caused by epoxy resin friction. If such damage is found, it should be repaired or replaced according to relevant standards and specifications.

[0046] After completing the maintenance work, control jack 410 to retract. During the retraction process, closely monitor the test results of the pressure detection device and displacement detection device to ensure a safe and smooth retraction process. Remove the second crossbeam 220, and then place the first crossbeam 210, the first connecting column 230, and the second connecting column 240 as a whole in the designated position for disassembly.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
