Description

Technical Field

[0001] This utility model relates to a positioning device for pre-embedded bolt groups in wind turbine foundation, specifically a positioning device for pre-embedded bolt groups in wind turbine foundation, belonging to the field of wind turbine foundation technology. Background Technology

[0002] The steel tower of a wind turbine is typically connected and fixed to the foundation by embedded components within the foundation concrete. Common embedded components include foundation rings and anchor bolts. Anchor bolts are a more structurally sound type of embedded foundation structure for wind turbine foundations, designed for optimal stress distribution. Embedded within the foundation concrete, the anchor bolts extend to the lower surface of the foundation cap and are separated from the concrete by external bolt sleeves. During the construction of wind turbine foundation piers, the positioning accuracy of the embedded bolts is crucial for the subsequent installation and stable operation of the wind turbine. Traditionally, embedded bolts are positioned using a positioning disc, utilizing the positioning ports on the disc. The positioning ports of the disc require extremely high precision during manufacturing, and once completed, their position is fixed. This design has significant limitations in actual construction because the construction site environment is complex and variable. Factors such as the flatness of the foundation and the actual required position of the embedded bolts may deviate from the design expectations. This makes it difficult for traditional positioning devices to be flexibly adjusted to meet the actual site conditions. If the position of the positioning port does not match the actual requirements, it may lead to inaccurate positioning of the embedded bolts, thereby affecting the overall quality of the wind turbine foundation pier and the installation accuracy of the subsequent wind turbine, causing numerous inconveniences and potential risks to the construction.

[0019] This utility model provides a positioning device for pre-embedded bolt groups in the foundation of a wind turbine pier.

[0020] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The device includes a device body 1, which includes a positioning disk 2 arranged in a linear array. The top of the positioning disk 2 is provided with a positioning port 15 arranged in a circular array. A fixing ring 3 is provided at the corresponding position of each positioning port 15 on the positioning disk 2. A threaded hole arranged in a circular array is provided on the outside of the fixing ring 3. A threaded component 4 is threadedly connected inside the threaded hole. Specifically, the positioning plate 2 only needs to have a positioning opening 15 made according to the approximate position of the pre-embedded bolt. The inner diameter of both the positioning opening 15 and the fixing ring 3 is larger than the outer diameter of the pre-embedded bolt. Depending on the actual situation, two methods can be selected: the positioning plate 2 can be pre-embedded together with the pre-embedded bolt, or the positioning plate 2 can be removed before pre-embedding. Generally, overall pre-embedding is adopted, which can avoid the pre-embedding being too complicated and avoid the problem that the disassembly of the positioning plate 2 will affect the positioning of the pre-embedded bolt. During the pouring process, the workers need to check the positioning of the pre-embedded bolt and the positioning of the positioning plate 2 regularly or in stages as the concrete pouring height changes, and adjust the threaded parts 4 on the positioning plate 2 in a timely manner. When overall pre-embedding is selected, the relevant structures of the thread setting, such as the screw 41 and the bolt 11, do not need to consider the issues of dust prevention and corrosion. To improve the positioning accuracy of the positioning plate 2, after the position of the threaded part 4 is adjusted and the positioning of the pre-embedded bolts is determined, spot welding can be performed on each threaded part 4 using a welding machine to fix the threaded part 4 on the fixing ring 3. This method can be determined according to the actual situation. Generally, tightening the threaded part 4 is sufficient. The pouring time is short, and after the pouring is completed, the concrete will form a positioning protection.

[0021] Example 2, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5The threaded part 4 includes a screw 41 and a contact plate 42. One end of the screw 41 has a round hole, and a rod 43 is inserted into the round hole. The end of the rod 43 away from the screw 41 is fixedly connected to the side wall of the contact plate 42. The side of the contact plate 42 away from the rod 43 has a V-shaped groove 44. Specifically, the pre-embedded bolt is placed inside the fixing ring 3, and then the corresponding screw 41 is rotated so that the contact plate 42 on the screw 41 contacts and squeezes the screw 41 through the inner wall of the V-shaped clamping groove 44, thereby fixing the screw 41; the inner wall of the V-shaped clamping groove 44 is coated with an anti-slip coating to improve the friction of the contact plate 42 and prevent the contact plate 42 from slipping when clamping the pre-embedded bolt.

[0022] Example 3, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 The outer side of the fixing ring 3 has circular holes arranged in a circumferential array. Nut 8 is fixedly installed on the outer side of the fixing ring 3 at the corresponding position of each circular hole. Nut 8 is threaded onto the outer side of the screw 41, and the screw 41 is located inside the circular hole. Specifically, a circular hole is normally opened on the retaining ring 3, and the inner diameter of the circular hole is larger than the outer diameter of the screw 41. The nut 8 is fixed to the retaining ring 3 by welding, which facilitates the positioning and adjustment of the screw 41.

[0023] Example 4, please refer to Figure 3 , Figure 4 and Figure 5 A limiting ring 9 is fixedly sleeved on the outside of the fixed ring 3, and a limiting plate 10 is slidably sleeved on the outside of the fixed ring 3. A connecting component is provided between the limiting plate 10 and the positioning plate 2. Specifically, the fixing ring 3 can be directly welded to the positioning plate 2, or it can be fastened to the positioning plate 2 by using the limiting plate 10 for snapping, and the bolts 11 and nuts 12 for fixing. The specific method depends on the actual needs. Generally, the first method is used because it is more stable.

[0024] Example 5, please refer to Figure 1 , Figure 5 The connecting assembly includes a bolt 11 and a nut 12. The nut 12 is threaded onto the outside of the bolt 11. The positioning plate 2 has two through holes 5 at the corresponding positions of each fixing ring 3. The top of the limiting plate 10 has a through hole 2. The bolt 11 is slidably disposed in the cavity between the through hole 5 and the through hole 2.

[0025] Example 6, please refer to Figure 4 The upper part of the positioning disk 2 has grooves 7 arranged in a circular array; Specifically, the positioning of the positioning plate 2 is generally done in a conventional way. Since the wind turbine foundation needs to be woven into a steel cage or steel mesh using steel bars during the pouring process, the position of the positioning plate 2 can be fixed to the steel mesh using connecting tools such as steel wire rope or cloth rope, or the steel positioning plate 2 can be directly welded to the corresponding position of the steel mesh, depending on the actual situation.

[0026] Example 7, please refer to Figure 1 and Figure 2 Between the two positioning disks 2, there is a support member 6 arranged in a circular array. The support member 6 includes a support rod 61 and a support tube 62. The support tube 62 is slidably sleeved on the outside of the support rod 61. The top end of the support tube 62 is rotatably connected to a support threaded sleeve 63, which is threadedly sleeved on the outside of the support rod 61.

[0027] Example 8, please refer to Figure 1 and Figure 2 The top end of the support rod 61 and the bottom end of the support tube 62 are rotatably connected to the connecting plate 13. The side of the connecting plate 13 away from the support rod 61 is rotatably connected to the connecting disk 14. The connecting disk 14 is fixedly set on the side wall of the corresponding positioning disk 2. Specifically, the connecting plate 14 is welded to the side wall of the corresponding positioning plate 2. The tilt angle of the corresponding positioning plate 2 is adjusted by rotating the support threaded sleeve 63. The adjustment of the support rod 61 requires the cooperation of multiple people. When assembling multiple positioning plates 2, they need to be assembled, welded and adjusted one by one from bottom to top, so as to make the positioning of the pre-embedded bolts more accurate. The support member 6 only plays a supporting role. The bottom positioning plate 2 needs to be fixed first. If the other positioning plates 2 are not fixed, the support member 6 is adjusted. After the support member 6 is adjusted, the other positioning plates 2 are welded and fixed. The support member 6 only plays a supporting and fine-tuning role. Whether to use it can be determined according to actual needs.

[0028] Working principle: Before positioning the embedded bolts, each embedded bolt needs to be set in the positioning port 15 on the positioning plate 2. At the same time, the positioning plates 2 are arranged in a linear array along the axial direction on the outside of the embedded bolts. Meanwhile, the positioning plates 2 and the embedded bolts need to be placed in the predetermined position of the wind turbine foundation. The distance between the two bottom positioning plates 2 is shortened, and the support members 6 are arranged in a circular array between the two positioning plates 2. According to the inclination direction of the pre-embedded bolts, adjust the corresponding fixing rings 3 of each layer one by one. The adjustment process only requires rotating each screw 41 to adjust the position of the screw 41 inside the fixing ring 3, so as to facilitate the adjustment of the inclination of the screw 41 for easy positioning. When it is necessary to adjust the height of the screw 41 or the overall inclination angle, simply rotate the support threaded sleeve 63 to adjust the overall inclination angle or height of the other positioning discs 2 while keeping the position of the bottom positioning disc 2 unchanged.
