Description

Technical Field

[0001] The utility model belongs to the technical field of wind turbine blades, and particularly relates to a measuring tool for the chordwise position of the web of a wind turbine blade. Background Technique

[0002] In recent years, the average rotor diameter of newly added wind turbines in China has increased from 129 meters in 2019 to 204 meters in 2024. The increase in rotor diameter means a significant increase in the length of wind turbine blades, and at the same time symbolizes that the blade industry has more stringent requirements for quality control. In the era of blade parity, in order to ensure the quality of blade products, the use of various low-cost and high-efficiency toolings has become a major trend in the lean quality management of the industry. As an important component for bonding the upper and lower molds in various types of wind turbine blades, the accuracy of the web positioning is of great significance to the blade quality.

[0003] When performing chordwise positioning of the web for blades containing main beam webs, auxiliary beam webs, and TEUD webs or blades with a length of one hundred meters, due to factors such as the excessive height of the web and the long distance from the mold edge, the obstruction of the web pressing tooling, or other web blockages, chordwise position measurement has become a major problem in the blade production process and also poses a major hidden danger to the quality stability of the blades. There is an urgent need to develop a measuring tool for the chordwise position of the web of a wind turbine blade to solve the problem of difficult chordwise positioning measurement of the web. Content of the Utility Model

[0004] The purpose of the utility model is to provide a measuring tool for the chordwise position of the web of a wind turbine blade to solve the problem of difficult chordwise positioning measurement of the web, and to greatly improve the forming quality and production efficiency of the blades.

[0005] To achieve the above purpose, the technical solution of the utility model is: a measuring tool for the chordwise position of the web of a wind turbine blade, including a laser level and a mold connection base, a height adjustment device, and a measurement fixing device arranged in sequence from bottom to top. The mold connection base can be installed on the mold flange. The height adjustment device is arranged between the mold connection base and the measurement fixing device and is used to adjust the height distance between the mold connection base and the measurement fixing device. The measurement fixing device is used to horizontally install the laser level, and the laser level is used to measure the chordwise position of the web.

[0006] Further, the mold connection base includes a horizontal plate and a profiling plate. One side of the horizontal plate is connected to the profiling plate. The horizontal plate is placed on the convex platform of the mold flange, and the profiling plate is profiled with the outer periphery of the mold.

[0007] Further, the height adjusting device includes a fixing member, an upper support rod and a lower support rod. The upper support rod is vertically slidably connected within the lower support rod. A plurality of first connection holes are arranged vertically on the upper support rod, and a plurality of second connection holes corresponding to the first connection holes are provided on the lower support rod. The fixing member fixes the upper support rod and the lower support rod through the first connection holes and the second connection holes.

[0008] Further, the measuring and fixing device includes a ruler support and a fixing frame. The lower side of the ruler support is mounted on the top of the height adjusting device. The ruler support is used for placing a laser level, and the fixing frame is used for fixing the laser level on the ruler support.

[0009] Further, the cross-section of the ruler support is an inverted U-shaped structure, and the top of the height adjusting device is horizontally slidably connected within the groove of the ruler support; the fixing frame includes a U-shaped frame and two sets of L-shaped frames. The horizontal sections of the two sets of L-shaped frames are respectively fixed to both sides of the open end of the U-shaped frame. The vertical sections of the L-shaped frames extend into the interior of the U-shaped frame. Two sets of sliding grooves are formed between the two sets of L-shaped frames and the inner sides of the U-shaped frame respectively. Both sides of the ruler support are slidably connected within the sliding grooves; when the lower side of the ruler support contacts the bottom of the sliding groove, the distance between the upper side of the U-shaped frame and the upper side of the ruler support matches the height of the laser level.

[0010] The installation process of this technical solution is as follows:

[0011] During the laying process, the excess cloth layer at the flange edge of the mold is trimmed. During the mold closing stage, the auxiliary materials at the flange edge of the mold are cleaned, and the vacuum sealing strip is bonded to the lower side area of the mold flange boss to ensure the conforming contact between the mold connection base and the mold flange boss.

[0012] 1. Fix the tooling to the flange edge of the mold, make the horizontal plate adhere firmly to the mold flange boss, and make the conforming plate conform to the outer periphery of the mold;

[0013] 2. Since the heights of the cross-sections of the web are different, adjust the height adjusting device at any time according to the height of the web. Vertically move the upper support rod to the appropriate height, and use the fixing member to fix the upper support rod and the lower support rod;

[0014] 3. Place the laser level on the ruler support, ensure that the level is in a horizontal state, and then use the fixing frame to fix the laser level on the ruler support to perform the measurement.

[0015] The beneficial effects of this technical solution are as follows:

[0016] 1. The measurement duration can be shortened, from the original 40 - 90 minutes to within 30 minutes, improving production efficiency.

[0017] 2. It can improve the measurement accuracy, ensure the product quality, and avoid potential product quality hazards caused by measurement errors. BRIEF DESCRIPTION OF THE DRAWINGS
