Description

Technical Field

[0001] This utility model belongs to the technical field, and in particular relates to a device for measuring the dimensions of wind turbine tower blanks. Background Technology

[0002] The wind turbine tower is the core supporting structure of a wind turbine generator set. Its function is to lift the huge wind turbine rotor and nacelle (including key equipment such as generators and gearboxes) to a height of tens or even hundreds of meters above the ground to capture stronger and more stable wind energy. The tower needs to withstand the enormous thrust, bending moment, and torque generated by the wind turbine, as well as its own enormous weight and wind load. Therefore, its structural safety and stability are crucial. The blanking dimensions of the wind turbine tower refer to the specific shape and size of the slab blanks (raw materials) planned and cut from the raw steel plate according to the design drawings and process requirements in the first step of the tower manufacturing process. These slab blanks are usually approximately trapezoidal or sector-shaped. During the blanking process, the dimensions of the blanks need to be measured, which requires precise measurement of the end face angles of the blanks used for the wind turbine tower.

[0003] However, existing dimensional measuring devices cannot clearly display the angles of two adjacent sides of a billet when measuring the end face angle, which affects the measurement results. Furthermore, the unevenness of the billet's end face leads to inaccurate measurements each time. Therefore, we provide a wind turbine tower blanking dimensional measuring device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a wind turbine tower blanking dimension measuring device. By rotating a single ring or double ring along the circumference of the I-shaped block, it is easy to realize the work of measuring angle dimensions. At the same time, the movable rod is controlled to slide along the path of the telescopic cylinder, which can be adjusted at will according to the position of the blank end face to ensure the accuracy of the measurement value.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a wind turbine tower blanking dimension measuring device, including an I-shaped block; a double collar is sleeved on the surface of the I-shaped block, and a single collar is sleeved on the surface of the I-shaped ring located inside the double collar. The ends of the double collar and the single collar away from the I-shaped block are bolted with telescopic cylinders. The ends of the telescopic cylinders away from the I-shaped block are provided with abutment wheels. A U-shaped plate is sleeved on the surface of the abutment wheel, and a movable rod that cooperates with the telescopic cylinder is fixed on the outer wall of the U-shaped plate.

[0007] The present invention is further provided that the end face of the I-shaped block has a notch, and a protractor is embedded inside the notch.

[0008] The present invention is further configured such that finger strips are fixed on the surface of both the double-ring and single-ring, and each finger strip is in contact with the surface of the protractor.

[0009] The present invention is further configured such that a limiting hole communicating with the inside of the telescopic cylinder is provided on the end face of the telescopic cylinder near the abutting wheel, and the diameter of the limiting hole is smaller than the inner diameter of the telescopic cylinder.

[0010] The present invention is further configured such that a circular plate located inside the telescopic cylinder is fixed to the end face of the movable rod passing through the limiting hole, and the periphery of the circular plate is in contact with the inner wall of the telescopic cylinder.

[0011] The present invention is further configured such that each end face of the circular plate is fixed with a spring sleeved on the movable rod, and the other end face of the spring abuts against the inner end face of the telescopic cylinder.

[0012] The present invention is further configured such that both ends of the abutment wheel are bolted with shaft plates, and the shaft of each set of shaft plates is rotatably connected to the corresponding U-shaped plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. Align the I-shaped block with the side edge of the billet and control the two sets of abutment wheels to rotate relative to each other so that the two sets of abutment wheels contact the surfaces of the two adjacent side walls of the billet respectively. After the two sets of abutment wheels can no longer rotate relative to each other, the angle between the two sets of abutment blocks can be directly observed. This allows you to measure and determine the angle between the two adjacent sides of the billet.

[0015] 2. When the side of the billet is uneven, the abutment wheel can be controlled to slide along the lateral direction of the telescopic cylinder, so that the abutment wheel moves away from the telescopic cylinder. In turn, the abutment wheel will drive the movable rod to move in the telescopic cylinder, thereby increasing the distance between the abutment wheel and the telescopic cylinder, so as to control the abutment wheel to move to a relatively flat position. At this time, the measurement work can continue. Attached Figure Description

[0024] 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.

[0025] Example 1

[0026] Please see Figures 1 to 5 This utility model is a wind turbine tower blanking dimension measuring device. By rotating the single ring 5 and the double ring 4 along the circumference of the I-shaped block 1, the angular dimension measurement can be easily realized. At the same time, the movable rod 302 is controlled to slide along the path of the telescopic cylinder 2, which can be adjusted at will according to the position of the blank end face to ensure the accuracy of the measurement value.

[0027] Specifically, there is an I-shaped block 1; a double-ring 4 is fitted on the surface of the I-shaped block 1, and a single-ring 5 is fitted on the surface of the I-shaped ring located inside the double-ring 4. The ends of the double-ring 4 and the single-ring 5 away from the I-shaped block 1 are bolted to a telescopic cylinder 2. The ends of the telescopic cylinder 2 away from the I-shaped block 1 are provided with abutting wheels 3. The surface of the abutting wheel 3 is fitted with a U-shaped plate 301. The outer wall of the U-shaped plate 301 is fixed with a movable rod 302 that works with the telescopic cylinder 2. The two ends of the abutting wheel 3 are bolted to a shaft plate 305. The shaft of each set of shaft plates 305 is rotatably connected to the corresponding U-shaped plate 301.

[0028] The operation process of this embodiment is as follows: When it is necessary to measure the size of the billet of the wind turbine tower, the I-shaped block 1 is aligned with and attached to the side edge of the billet, and the two sets of abutment wheels 3 are controlled to rotate relative to each other, so that the two sets of abutment wheels 3 respectively contact the surfaces of the two adjacent side walls on the billet. After the two sets of abutment wheels 3 can no longer rotate relative to each other, the angle value between the two sets of abutment blocks can be directly observed. In this way, the angle between the two sets of adjacent sides of the billet can be measured and determined. At the same time, when there is unevenness on the side of the billet, the abutment wheel 3 can be controlled to slide along the lateral direction of the telescopic cylinder 2, so that the abutment wheel 3 moves away from the telescopic cylinder 2. Then the abutment wheel 3 will drive the movable rod 302 to move in the telescopic cylinder 2, thereby increasing the distance between the abutment wheel 3 and the telescopic cylinder 2, so as to control the abutment wheel 3 to move to a relatively flat position, and then the measurement work can continue.

[0029] Example 2

[0030] Please see Figure 1 , Figure 2 and Figure 3 Based on Example 1, the angles of two adjacent sides of the blank can be easily and intuitively determined by the cooperation between the protractor 101 and the two sets of finger strips 6.

[0031] Specifically, the end face of the I-shaped block 1 has a notch 102, and a protractor 101 is embedded inside the notch 102. Finger strips 6 are fixed on the surface of both the double ring 4 and the single ring 5, and each finger strip 6 is in contact with the surface of the protractor 101.

[0032] The operation process of this embodiment is as follows: When the double ring 4 and the single ring 5 rotate relative to each other on the surface of the I-shaped block 1, the double ring 4 and the single ring 5 will drive the finger strip 6 to rotate along the surface of the protractor 101. Therefore, the user can determine the angle between the two sets of finger strips 6 according to the protractor 101, so as to quickly measure the angle between the two sets of adjacent sides of the blank.

[0033] Example 3

[0034] Please see Figure 2 and Figure 5 Based on Example 1, the spring 303 pushes the circular plate 304, thereby ensuring that the abutment wheel 3 can be quickly reset.

[0035] Specifically, the end face of the telescopic cylinder 2 near the abutting wheel 3 is provided with a limiting hole 201 that communicates with the inside of the telescopic cylinder 2, and the diameter of the limiting hole 201 is smaller than the inner diameter of the telescopic cylinder 2. The movable rod 302 passes through the end face of the limiting hole 201 and is fixed with a circular plate 304 located inside the telescopic cylinder 2. The periphery of the circular plate 304 is connected to the inner side wall of the telescopic cylinder 2. The end face of the circular plate 304 is fixed with a spring 303 sleeved on the movable rod 302, and the other end face of the spring 303 abuts against the inner end face of the telescopic cylinder 2.

[0036] The operation process of this embodiment is as follows: When the abutting wheel 3 moves away from the telescopic cylinder 2, the abutting wheel 3 will drive the movable rod 302 to slide inside the limiting hole 201. Then the movable rod 302 will drive the circular plate 304 to move inside the telescopic cylinder 2. Then the circular plate 304 will compress the spring 303. Therefore, when the abutting wheel 3 is released, the spring 303 will directly push the circular plate 304 to reset in the telescopic cylinder 2, thereby directly driving the abutting wheel 3 to reset to the initial position.
