Description

Technical Field

[0001] This utility model relates to the field of power engineering equipment technology, specifically to a special tool for assembling mixed towers of different sizes. Background Technology

[0002] With the rapid development of the wind power industry, concrete towers are being used more and more widely in wind turbine generators. Compared with traditional cast-in-place concrete towers, prefabricated concrete towers have gained widespread recognition in the industry due to their advantages such as fast construction speed, easy quality control, and environmental friendliness.

[0003] Among them, precast concrete tower segmentation technology, as an advanced construction method, effectively improves construction efficiency and quality control by dividing the tower into multiple segments, prefabricating them in a factory, and then transporting them to the site for assembly. However, existing pre-assembly tools and methods face many challenges during the on-site pre-assembly of precast concrete tower segments, as follows:

[0004] First, traditional assembly platforms lack sufficient size adaptability and are difficult to quickly adjust to accommodate mixed towers of different diameters. This means that tools need to be reconfigured or adjusted every time the tower section specifications are changed, which seriously affects construction efficiency.

[0005] Second, the positioning accuracy of existing tools is limited, and the positional deviation of the mixed tower segments is prone to occur during the assembly process, affecting the roundness and verticality of the tower, and thus threatening the safety and stability of the overall structure.

[0006] Third, traditional methods usually rely on manual adjustment and fixing, which is complicated and requires high skills from workers, thus affecting assembly efficiency.

[0007] Therefore, there is an urgent need in this field for a special tool for pre-assembling mixed towers that can adapt to different size specifications, provide precise positioning, be easy to operate and have high leveling accuracy. This is a technical problem that those skilled in the art need to solve.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] See Figures 1-3 To address the problems mentioned in the background section, this utility model provides a special tool for assembling mixed towers of different sizes, thereby solving the aforementioned technical problems. The technical solution is as follows:

[0027] A special tool for assembling mixed towers of different sizes includes: a central frame 110, a support beam 120, a tie rod 130, a leveling leg 150, and a clamping component 140; the central frame 110 is octagonal;

[0028] Multiple support beams 120 are provided, and the multiple support beams 120 are arranged in a circular array around the central frame 110, and the inner end of each support beam 120 is fixed to the side of the central frame 110.

[0029] Each support beam 120 has a number of positioning holes 121 spaced radially on its top surface;

[0030] Two adjacent support beams 120 are fixedly connected by tie rods 130;

[0031] The clamping member 140 is adjustablely fixed to the positioning hole 121 of the support beam 120 by positioning bolts, and the inner side of the clamping member 140 forms a limiting surface for positioning the concrete tower tube segments.

[0032] In this embodiment, the clamping member 140 includes a base plate 141 and a limiting plate 142 fixed on the base plate 141;

[0033] The base plate 141 has mounting holes 143; the positioning bolts pass through the mounting holes 143 and connect to the positioning holes 121 on the support beam 120 to achieve adjustable fixing of the top clamping member 140.

[0034] It should be noted that the base plate is fixed to the support beam by positioning bolts through the mounting holes on it and the positioning holes of the support beam. The radial position of the clamping component on the support beam can be flexibly adjusted to adapt to different sizes of mixed tower segments. The limiting plate fixed to the base plate forms a limiting surface that matches the outer wall of the segment, which can closely fit the segment to achieve reliable positioning and ensure assembly accuracy.

[0035] In this embodiment, the limiting surface of the clamping member 140 is an arc surface that matches the outer wall of the concrete tower segment. The arc surface can closely fit the outline of the segment, limit the lateral displacement of the segment, ensure the stability of the segment position during pre-assembly, and provide a guarantee for the subsequent assembly accuracy.

[0036] In this embodiment, the leveling support leg 150 includes a leveling bolt 152 and a pad 153 fixed to the bottom of the leveling bolt 152.

[0037] In this embodiment, a nut 151 is fixedly connected to the leveling bolt 152, and a radial rod is fixed on the outer wall of the nut 151.

[0038] The nut 151 is fixedly connected to the leveling bolt 152, which can be secured by welding. The radial rod extends the lever arm, allowing operators to easily rotate the nut without large tools, thus achieving precise fine-tuning of the leveling bolt's height.

[0039] In this embodiment, eight support beams 120 are provided, and the eight support beams 120 are evenly distributed around the central frame 110.

[0040] The following is a method for using a special tool for assembling mixed towers of different sizes, provided by this embodiment of the utility model:

[0041] (1) First, assemble the central frame 110 and the leveling legs 150 below it, and place them stably on the preset pads. Then, install eight support beams 120 in sequence, ensuring that they are evenly distributed in a circular array around the central frame 110, and connect adjacent support beams with tie rods 130 to enhance overall stability; leveling legs 150 are installed below the outer end of each support beam 120.

[0042] (2) After the assembly is completed, the top surface of the assembly platform is initially leveled: the midpoint of the outer end of the top surface of the eight support beams 120 is used as the measurement point. By rotating the leveling bolt 152, the extension length of the leveling bolt 152 is adjusted to control the height deviation of each measurement point within ±2mm, and the initial leveling data is recorded.

[0043] (3) Determine the required assembly radius based on the design dimensions of the concrete tower segments to be assembled. Connect and fix the base plate 141 of the clamping member 140 to the corresponding positioning holes 121 on the support beam 120 using positioning bolts. By selecting different positioning holes 121, the radial position of the clamping member 140 can be precisely adjusted so that the limiting surface formed by its arc-shaped limiting plate 142 matches the target assembly radius.

[0044] (4) The concrete tower segments are hoisted to the assembly platform in a clockwise order of a, b, c, and d. First, install segments a and c, ensuring their outer walls are flush against the limiting surfaces of the corresponding clamping members 140. Then, install segment b, adjusting the height of the supporting legs below the corresponding support beams according to site requirements. Once the appropriate position is reached, pre-install the bolts. After installing segments a, b, and c, continue installing segment d.

[0045] (5) After the initial installation of all segments a, b, c, and d is completed, the final fine leveling adjustment is carried out: taking the intersection of the center line of the top surface of the eight supporting beams 120 and the inner side of the segment as the measuring point, each leveling support leg 150 is precisely adjusted to control the height deviation of the platform top surface within ±1mm. After confirming that the position of all segments is accurate and the joints meet the requirements, all segment connecting bolts are tightened to the specified torque to complete the pre-assembly of the mixed tower segments and wait for the overall hoisting.

[0046] It should be noted that in step (4) above, if the b segment deviates during the installation process, a hydraulic jack can be used to make fine adjustments. The hydraulic jack can be fixed to the positioning hole of the corresponding support beam 120 by positioning bolts.

The components shown as units may or may not be physical units; they may be located in one place or distributed across multiple network units.
