Description

Technical Field

[0001] This utility model relates to the field of correction devices, specifically a tower flange welding deformation correction device. Background Technology

[0002] The tower is generally composed of three, four or five sections connected by flanges. Each section is made up of several single sections of the cylinder. The ellipticity of the finished single section of the tower flange must meet the technical requirements of ≤3mm. This is to ensure that the normal installation of the equipment on site is not affected and to ensure the safe operation of the subsequent wind turbine generator. Therefore, the tower flange needs to be corrected. A search revealed that invention patent CN117139416A discloses a high-precision correction device for welding deformation of wind turbine tower flanges. The technical solution includes a base box, a base, and a three-jaw chuck. An encoder is mounted on one side of the base via a shaft bracket. A measuring wheel is mounted on the bottom of the encoder via a shaft. A rotating disk is rotatably mounted at the center of the base. A turbine is fixedly mounted on the top of the rotating disk, and the three-jaw chuck is clamped to the top of the turbine via a clamping rod. This device uses the measuring wheel to rotate synchronously with the rotating disk, allowing real-time recording of the rotating disk's rotation angle. The electrical signal of the rotation angle recorded by the measuring wheel is transmitted to the encoder for calculation. The encoder controls a servo motor to operate based on the calculation result, thus facilitating precise control of the three-jaw chuck's rotation angle and enabling precise adjustment based on the flange's correction position held by the three-jaw chuck, thereby improving the accuracy of flange welding deformation correction.

[0003] However, existing calibration devices, when in use, are prone to uneven stress distribution because the flanges are subjected to force from the same vertical direction, affecting the calibration effect. Furthermore, they lack applicability to flanges of different diameters. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a tower flange welding deformation correction device, which solves the problem that existing correction devices are prone to uneven force distribution when in use because the flange is subjected to force from the same vertical direction, thus affecting the correction effect.

An adjusting rod is threadedly connected to the bottom of the hollow shell, and the adjusting rod penetrates the hollow shell. One end of the adjusting rod, located inside the hollow shell, is fixedly connected to a disc, which abuts against the ramp block. This adjustable correction mechanism allows for the correction of flanges of different diameters.

[0013] 2. This utility model sets a linkage plate at the bushing between the motor and the adjustable correction mechanism. The linkage plate can be driven to rise and fall by a hydraulic cylinder and a guide column. At the same time, a square rod is set on the bushing, which can be inserted into the output shaft of the motor. In this way, the height position of the adjustable correction mechanism can be controlled by the hydraulic cylinder, so that it applies vertical downward pressure to the flange. In conjunction with the rotation driven by the motor, the entire surface of the flange can be corrected, thereby improving the correction effect. Attached Figure Description

The guide post 11 helps to balance the force on the linkage disc 9 during lifting and lowering.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The bottom of the bushing 6 is provided with an adjustable correction mechanism 8. The adjustable correction mechanism 8 can be used to correct flanges 3 of different diameters. The adjustable correction mechanism 8 includes a hollow shell 81 fixedly connected to the bottom of the bushing 6. Multiple slides 82 are slidably connected to the side of the hollow shell 81 and the slides 82 are set through the hollow shell 81. One end of the slide 82 is fixedly connected to a pressure seat 83 and the pressure seat 83 abuts against the flange 3. The other end of the slide 82 is fixedly connected to a inclined block 84. The bottom of the hollow shell 81 is connected to an adjusting rod 87 by a thread and the adjusting rod 87 is set through the hollow shell 81. One end of the adjusting rod 87 located inside the hollow shell 81 is fixedly connected to a disc 89 and the disc 89 abuts against the inclined block 84.

Then, after the electromagnetic plate 2 is energized, it attracts the flange 3. At the same time, the motor 5 drives the bushing 6 to rotate through the square rod 7, and the bushing 6 drives the adjusting correction mechanism 8 to rotate, thereby using the pressure seat 83 to correct the entire surface of the flange 3. In addition, by rotating the adjusting rod 87 through the knob 88, the adjusting rod 87 moves upward through the threaded movement between it and the hollow shell 81. Then, the adjusting rod 87 drives the disc 89 to move, and the disc 89 applies a radial outward pushing force from the hollow shell 81 to each inclined block 84. This can control the spacing between each pressure seat 83, which can meet the correction of flanges 3 of different diameters and improve the applicability of the device.
