Description

Technical Field:

[0001] The utility model relates to the technical field of measuring equipment, and particularly relates to a device for measuring the flatness of a flange of a wind power tower barrel. Background Art:

[0002] In the production of the tower barrel, the flatness of the connecting flange is a very important index, which will directly affect the installation and use effect of the tower barrel. If the flatness of the flange does not meet the requirements and there are gaps during the connection of the tower barrel, it will lead to problems such as reduced sealing effect of the tower barrel, air leakage, liquid leakage, etc., and will also affect the overall verticality of the tower barrel. Therefore, it is very necessary to measure the flatness of the flange components at a ratio of 10% at the stage when the raw materials arrive at the factory.

[0003] At present, to measure the flatness of the flange, an integral platform is used or the measurement is directly carried out on the ground. If an integral platform is used, according to the outer diameter size of the tower barrel flange (the maximum outer diameter is about φ7000mm at present), the integral platform applicable is huge in size, inconvenient to carry, and requires a large amount of materials and high costs during manufacturing; if the measurement is directly carried out on the ground, the requirement for the flatness of the ground is relatively high, so the flatness of the contact surface cannot be guaranteed, which has a great impact on the measurement of the flatness of the flange. Content of the Utility Model:

[0004] The purpose of the utility model is to provide a device for measuring the flatness of a flange of a wind power tower barrel to solve the above technical problems.

[0005] The purpose of the utility model is implemented by the following technical solution: A device for detecting the flatness of a flange of a wind power tower barrel includes a plurality of support seats for supporting the flange of the tower barrel. Each of the support seats is evenly distributed in a ring shape. The support seat includes a base, an adjusting component is fixedly arranged above the base, a support component is fixedly arranged above the adjusting component. The support component includes a connecting plate at the bottom and a support plate at the top. The connecting plate and the support plate are fixedly connected by a connecting piece. The connecting plate is fixedly connected with the adjusting component. The adjusting component can adjust the height of the support component up and down. The surfaces of the support plates of each support component are in the same horizontal plane.

[0006] Further, an anti-falling block is fixedly arranged on the support plate, and a rubber pad is arranged on the upper surface of the support plate.

[0007] Further, the adjusting component is a screw structure, which includes a bottom plate and a plurality of screws. A plurality of the screws are vertically fixed on the bottom plate. The plurality of screws pass through the connecting plate and are fixedly connected by two locking nuts. The bottom plate is fixedly connected above the base.

[0008] Further, the adjusting component is a hydraulic push rod, the base of the hydraulic push rod is fixedly connected above the base, and the telescopic rod of the hydraulic push rod is fixedly connected to the connecting plate.

[0009] Further, the base includes a lower bottom plate and an upper top plate, and the upper top plate and the lower bottom plate are fixedly connected by vertical support plates arranged vertically.

[0010] Further, reinforcing plates perpendicular to the vertical support plates are fixedly provided on both sides of the vertical support plates.

[0011] Advantages of the present utility model: The present utility model arranges multiple support seats in a circular and evenly distributed manner, and the surfaces of the support plates are on the same horizontal plane. By placing the tower barrel flange on the support seats, the flatness of the tower barrel flange can be effectively detected. At the same time, it can be adjusted arbitrarily according to the different sizes of the actually detected tower barrel flanges, and its applicability is high; by adjusting the height of the surface of the support plate through the adjusting component, it is ensured that the surfaces of each support plate are on the same horizontal plane, and the requirement for the flatness of the site ground is low, and its applicable scenarios are more extensive.

When measuring the flatness of the tower flange, according to the size and measurement accuracy requirements of the tower flange to be measured, a certain number of support seats 10 are selected, and a plurality of support seats 10 are arranged evenly in a ring and placed on the ground. Then, the height of the support component 3 is adjusted by the adjustment component 2 to make the surfaces of each support plate 32 on the same horizontal plane. A laser leveling instrument can be used to level the surface of the support plate 32. After the surfaces of all the support plates 32 are on the same horizontal plane, the tower flange to be measured is placed on the support seat 10, and the flatness of the tower flange to be measured can be measured.
