Description

Technical Field

[0001] The utility model belongs to the technical field of detection, and particularly relates to a detection scale for internal parts of a tower barrel. Background Art

[0002] The wind turbine tower barrel is a key device in a wind turbine. It is usually formed by welding multiple sections of barrel joints and welding flanges at both ends to form a semi-finished barrel section. After the barrel section is welded, it is sandblasted, painted and equipped with relevant accessory parts to form a finished barrel section. The finished barrel section is transported to the wind turbine installation site for connection to form an integral wind turbine tower barrel.

[0003] The wind turbine tower barrel usually includes a barrel body and a large number of accessory structures inside it. The accessory structures include beam support plates, platform support plates, cable brackets, ladder support connection plates, connection columns, lifting ring connection plates and support bracket connection plates, etc. After the accessory structures are installed, special inspectors will check the positions and dimensions of each accessory structure against the design drawing to see if they are consistent with the drawing. In the prior art, the detection is usually carried out by a scale or a tape measure. As Figure 1 shown, 3 is the beam support plate and 4 is the platform support plate. During the detection, usually with the axis of the barrel body as the coordinate origin, the barrel body is divided into four quadrants.

[0004] When the applicant was actually detecting, a large number of repeated and symmetric structures were found. For such structures, it is only necessary to detect the distance between two components. This patent is a detection scale specifically for detecting the structures inside the tower barrel. Content of the Utility Model

[0005] In order to solve the above problems, the embodiment of the utility model provides a detection scale for internal parts of a tower barrel. The positioning rings at both ends are used to detect repeated and symmetric structures (the number is very large and the detection method is very simple). This detection usually does not require the use of an extension ruler (that is, the distance is usually less than 2m). For asymmetric structures, three positioning rings are required to cooperate. The middle positioning ring is aligned with the corresponding reference line (usually drawn). In this case, an extension ruler may or may not be used. The technical solution is as follows:

[0006] An embodiment of the utility model provides a detection scale for inner components of a tower barrel, which includes a scale 1. Scale lines are arranged on the scale 1 along its direction. The detection scale for inner components of the tower barrel further includes three positioning rings 2, multiple tips 5 with different lengths, and one or two extension rulers. The extension ruler is detachably or telescopically arranged at the end of the scale 1, and it forms a ruler body with the scale 1. The scale 1 is in a circular tube structure, and the scale lines thereon take the midpoint of the scale 1 as the zero point and increase towards both ends. The scale lines of the extension ruler are matched with those of the scale 1. The three positioning rings 2 are sleeved outside the ruler body and can be adjusted along the direction of the ruler body. The middle positioning ring 2 is located at the zero point, and tips 5 with corresponding lengths are detachably arranged on its circumferential surface. The tips 5 are arranged radially along the positioning ring 2 and their lengths can be adjusted.

[0007] Further, two locking bolts 6 are oppositely arranged on the positioning ring 2 in the embodiment of the utility model. The locking bolts 6 are arranged radially along the positioning ring 2, and their inner ends abut against the ruler body to fix the positioning ring 2 on the ruler body. The positioning ring 2 can be adjusted by loosening the two locking bolts 6. For the middle positioning ring 2, the tip 5 is perpendicular to the connection line of the two locking bolts 6.

[0008] Among them, one end of the tip 5 in the embodiment of the utility model is a tip, and the other end is a screw. A screw hole matched with the screw is arranged radially on the circumferential surface of the middle positioning ring 2. Two flat nuts 7 are arranged side by side on the screw and are threadedly connected with the screw hole. The flat nut 7 close to the positioning ring 2 abuts against the circumferential surface of the positioning ring 2.

[0009] Specifically, the scale lines in the embodiment of the utility model are arranged on the side surface of the ruler body. Numerical values are arranged above the corresponding scale lines at the top of the ruler body. The tip 5 is located at the bottom of the positioning ring 2, and the two locking bolts 6 of the two positioning rings 2 at both ends are respectively located at the top and the bottom.

[0010] Preferably, the number of the extension rulers in the embodiment of the utility model is one. It is detachably arranged at one end of the scale 1. It is in the same circular tube structure as the scale 1 and is connected with the scale 1 through threads. An external thread joint is coaxially arranged at one end of the extension ruler close to the scale 1. Internal threads matched with the external thread joint are arranged on the inner walls at both ends of the scale 1. The external thread joint is located inside the end of the scale 1 and is threadedly connected with the internal thread.

[0011] Specifically, the length of the scale 1 in the embodiment of the utility model is 2m, the minimum scale of the scale lines is 1cm, and the length of the extension ruler is less than or equal to 0.6m.

[0012] Specifically, the outer diameter of the scale 1 in the embodiment of the utility model is 30mm. The inner diameter of the positioning ring 2 is in clearance fit with the scale 1. Its outer diameter is 90mm, and its thickness is 40mm.

[0013] The beneficial effects brought by the technical solution provided by the embodiment of the present utility model are as follows: The embodiment of the present utility model provides a detection scale for internal components of a tower barrel. The positioning rings at both ends are used to detect repetitive and symmetric structures (the quantity is very large, and the detection method is very simple. For example, at the marked position 1106 and the marked position 17° as shown in Figure 1 , the marked position 1106 repeats twice, and the marked position 17° repeats 10 times). It is to detect whether two structures are aligned with the two positioning rings. This detection usually does not require the use of an extension ruler (that is, the distance is usually less than 2m). For asymmetric structures (such as Figure 1 at the marked positions 803 and 1503), three positioning rings are required for cooperation. The middle positioning ring is aligned with the corresponding reference line. In this case, it may or may not require the use of an extension ruler (in this case, an extension ruler is required). Adjust the positioning rings at both ends to align with the corresponding structures, and detect whether the two structures are aligned with the two positioning rings. The asymmetric structure also repeats twice. After adjusting the positioning rings, it can be measured twice. In short, due to a large number of repetitive and symmetric structures, the number of adjustments of the positioning rings can be reduced, the working intensity can be lowered, and the detection speed can be improved. In addition, since the detection is carried out by the detector inside the tower barrel and the space inside the tower barrel is limited, in this patent, the extension ruler is detachable or telescopic. In most cases, the extension ruler is not used, and the extension ruler is removed or retracted, reducing the length of the ruler body. This not only facilitates the operation but also can improve the detection speed. Description of the Drawings
