[0002] The wind turbine tower is an important part of the wind power generation system, supporting the wind turbine and its components (such as the nacelle and blades). It needs to have high strength and stability to withstand the pressure of wind and other external environments. The wind turbine door frame is the door frame structure at the bottom or middle section of the wind turbine tower. The wind turbine door frame is used for personnel to enter and exit the tower for maintenance and inspection, and is also used for the entry and exit of equipment and tools.

[0003] Since wind turbine towers are mostly formed in one piece, it is necessary to cut the wall of the wind turbine tower to form a wind turbine door frame structure. The current traditional cutting method is that workers enter the interior of the wind turbine tower and then cut it using handheld cutting equipment. This cutting method not only has low production efficiency and high labor intensity, but also cannot fine-tune the cutting position, has poor cutting accuracy, and is prone to errors, making it difficult to meet the processing quality requirements of wind turbine door frames. Therefore, in view of the above problems, the utility model provides a special cutting device for wind turbine door frames, which is of great significance. Utility Model Content

The rotational motion of the motor can be converted into the linear motion of the X-axis slider 5 and the Y-axis slider 8 through a lead screw or a belt. An electric telescopic rod 9 is installed on the Y-axis slider 8. The bottom end of the output shaft of the electric telescopic rod 9 is fixedly connected to a mounting seat 10. A cutting mechanism 11 is installed on the mounting seat 10. The cutting mechanism 11 is an existing oxygen-acetylene cutting machine product on the market. Its main structure includes an oxygen cylinder, an acetylene cylinder, a pressure reducing valve, a gas hose, a cutting torch, a flashback preventer, etc. When it is necessary to cut the tower of a wind turbine generator, First, open the pressure reducing valves on the oxygen cylinder and acetylene cylinder, adjust the output pressure, and introduce oxygen and acetylene into the mixing chamber of the cutting torch through the gas hose. Then open the acetylene valve on the cutting torch handle to let acetylene gas flow out slightly. Use the igniter to ignite the acetylene to produce an initial flame. Slowly open the oxygen valve on the cutting torch handle and adjust the oxygen flow rate to make the flame reach the ideal cutting temperature and shape to form a neutral flame (without excess oxygen or acetylene). Then bring the cutting torch nozzle close to the surface of the wind turbine tower and use the flame to preheat the metal on the tower surface to the ignition point. During the process, the flame mainly relies on acetylene combustion to provide heat, so that the metal surface reaches a red-hot state. When the metal on the tower surface reaches the ignition point, the cutting oxygen valve on the cutting torch is pressed to spray high-pressure oxygen. The high-pressure oxygen reacts with the preheated metal to oxidize the metal and blow away the oxide to form a cutting seam. Then the cutting mechanism 11 is moved to make the cutting torch cut the metal on the tower surface along a predetermined cutting line until the cutting of the wind turbine door frame is completed. The cutting mechanism 11 can be driven up and down by driving the electric telescopic rod 9 so as to adjust the cutting height of the cutting mechanism 11 as needed.

[0025] Among them, the transverse frame 2 and the longitudinal frame 3 are arranged in double layers along the height direction of the supporting leg 1, and the angle between the transverse frame 2 and the longitudinal frame 3 is 90°. The cutting equipment can be supported and reinforced by the mutual cooperation between multiple transverse frames 2, longitudinal frames 3 and the supporting leg 1, so as to improve the stability of the entire cutting equipment.

A foot 12 is provided at the bottom of each support leg 1, and a layer of rubber pad is provided on the bottom surface of the foot 12. When the cutting equipment is sent into the tower, the support leg 1 can play a supporting role so as to fix the cutting equipment in the tower for use. The foot 12 at the bottom of each support leg 1 is in contact with the inner wall of the tower. At this time, the rubber pad can play a buffering and protective role to prevent the inner wall of the tower from directly contacting the foot 12 and causing collision and wear.

The X-axis slider 5 is slidably connected to the X-axis guide rail 4. The driving mechanism 6 can drive the X-axis slider 5 to translate along the X-axis guide rail 4 in the X-axis direction. When the X-axis slider 5 moves, it can drive the Y-axis guide rail 7 together with the cutting mechanism 11 to move, so as to fine-tune the cutting position of the cutting mechanism 11 in the X-axis direction, thereby effectively improving the cutting accuracy of the cutting equipment.

[0028] Among them, the Y-axis guide rail 7 is longitudinally fixed on the longitudinal frame 3, and the Y-axis slider 8 is slidably connected to the Y-axis guide rail 7. The driving mechanism 6 can drive the Y-axis slider 8 to translate along the Y-axis guide rail 7 in the Y-axis direction. When the Y-axis slider 8 moves, it can drive the cutting mechanism 11 to move together, so as to fine-tune the cutting position of the cutting mechanism 11 in the Y-axis direction, thereby further improving the cutting accuracy of the cutting equipment and effectively avoiding cutting errors.
