[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. The principle is to convert the kinetic energy of wind into mechanical kinetic energy, and then convert the mechanical energy into electrical kinetic energy. This is wind power generation. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed of rotation through a speed increaser to drive the generator to generate electricity.

[0003] The wind turbine main shaft is one of the important components of wind power generation.

In order to perform automatic cutting action, a plurality of rail plate air grooves 8 arranged in a rectangular shape are provided at the center of the cutting rail plate 1. By providing the rail plate air grooves 8 with a larger diameter, ventilation can be performed under the automatic cutting machine 2. A connecting vertical plate 9 fixedly connected to the cutting rail plate 1 is provided directly below the rail inner plate 7, and a bottom support plate 11 is fixed at the bottom of the connecting vertical plate 9, so that the bottom support plate 11 and the connecting vertical plate 9 form an inverted T-shaped structure, and a plurality of vertical plate exhaust holes 10 distributed at intervals are provided laterally on the surface of the connecting vertical plate 9, so that the bottom support plate 11 is attached to the upper end surface of the heavy alloy steel, so that the cutting rail plate 1 is propped up, and there is space under the cutting rail plate 1, and the airflow can be enhanced through the vertical plate exhaust holes 10. At the same time, the bottom support plates 11 distributed on both sides are attached to the upper end of the heavy alloy steel and also have stability.

[0039] The bottom support plate 11 is fixed with a bent convex plate 12 extending upward at the end near the center of the cutting track plate 1, so that a U-shaped moving groove 13 is formed between the bent convex plate 12 and the connecting vertical plate 9, and a moving side block 29 of the rectangular shape structure is slidably connected in the groove of the moving groove 13, a moving frame rod 14 is fixed on the top of the moving side block 29, and a clamping main plate 15 is provided below the center of the moving frame rod 14, and the moving frame rod 14 and the moving side block can be driven by clamping the main plate 15 29 moves under the cutting track plate 1, and two groups of clamping main plates 15 are provided, and two groups of movable frame rods 14 connected to the clamping main plates 15 are also provided. The two groups of clamping main plates 15 move under the cutting track plate 1, so that the opposite surfaces of the two groups of clamping main plates 15 can be clamped on both sides of the heavy alloy steel, and the bottom support plate 11 is attached to the upper end of the heavy alloy steel, so that the entire cutting track plate 1 can be stably placed on the heavy alloy steel, so that the automatic cutting machine 2 can move along the cutting track plate 1 more stably.

[0040] A limiting side groove portion 31 arranged with a horizontal spacing is set on the end surface of the connecting vertical plate 9 close to the movable side block 29, and a side block inner groove 30 is set inside the movable side block 29. A movable side block portion 40 that can be laterally moved outward from the side block inner groove 30 is set in the side block inner groove 30, and a limiting side protrusion 41 that can extend into the groove of the limiting side groove portion 31 is fixed on the surface of the movable side block portion 40. After clamping the side surface on which the main sticking plate 15 is attached when the movable frame rod 14 moves to the specified position, the movable side block portion 40 is moved outward from the side block inner groove 30 by operating the movable side block portion 40, so that The limiting side protrusion 41 at the front end of the moving side block portion 40 is inserted into the limiting side groove portion 31 to limit the moving frame rod 14, thereby completing the clamping effect of the clamping main plate 15 on the heavy alloy steel. In order to achieve the above effect, the moving frame rod 14 is connected to the top of the clamping main plate 15, and a clamping rod transverse hole 28 connected to the side block inner groove 30 is opened in the moving frame rod 14. A sliding cross bar portion 39 fixedly connected to the moving side block portion 40 is slidably connected in the clamping rod transverse hole 28, and the other end of the sliding cross bar portion 39 passes through the clamping main plate The side groove 33 of the side of the clamping main plate 15 enters into the cavity of the clamping main plate 15, and a pressure plate connecting plate 34 is arranged in the cavity of the clamping main plate 15, so that the pressure plate connecting plate 34 can move laterally in the cavity of the clamping main plate 15, and a side pressure rod 32 extending to one side through the clamping main plate 15 is fixed at the bottom of the pressure plate connecting plate 34. By pressing the side pressure rod 32 toward the inside of the clamping main plate 15, the pressure plate connecting plate 34 connected to the side pressure rod 32 can drive the sliding cross bar 39 and the moving side block 40 to move, so that the limiting side convex The block 41 is disengaged from the limiting side groove portion 31 to realize the displacement of the clamping main plate 15, and a plurality of sets of clamping side springs 35 are fixed on the surface of the pressure plate connecting plate 34, and the other end of the clamping side spring 35 is attached to the inner wall of the cavity of the clamping main plate 15. When the side pressure rod portion 32 is released, the elasticity of the clamping side spring 35 causes the sliding cross bar portion 39 to move in the opposite direction, so that the limiting side protrusion 41 is re-engaged in the moving groove 13, and the position of the clamping main plate 15 can be fixed, thereby completing the preliminary limiting of the clamping main plate 15 to clamp the heavy alloy steel side wall.

[0041] A plurality of rack bottom grooves 16 are provided at the bottom of the movable rack rod 14, and a plurality of plate top blocks 17 are fixedly provided on the top of the clamping main plate 15, which are slidably connected in the rack bottom grooves 16. After the movable rack rod 14 is fixed in position, the clamping main plate 15 can also be moved under the movable rack rod 14 to reduce the gap between the clamping main plate 15 and the heavy alloy steel, thereby improving the stability of the entire cutting track plate 1 attached to the heavy alloy steel. An adjusting screw portion 21 is provided between the front and rear sets of clamping main plates 15, wherein the surface of the front clamping main plate 15 is rotatably connected to the shaft cylinder 20, so that the adjusting screw portion 21 is threadedly connected to the shaft cylinder 20, and the other end of the adjusting screw portion 21 is fixedly provided in the clamping main plate 15 at the rear side. As the adjusting screw portion 21 is pushed in the rotating shaft tube 20, the rotating shaft tube 20 will rotate, so that the distance between the two sets of clamping main plates 15 is shortened. After the position adjustment of the two sets of movable frame rods 14 is completed, the distance between the two sets of clamping main plates 15 can be adjusted by pushing the adjusting screw portion 21, so that the gap between the clamping main plates 15 and the heavy alloy steel is further filled, and the stability of the cutting track plate 1 and the automatic cutting machine 2 is further improved. After the clamping main plates 15 are further adjusted, the clamping main plates 15 need to be locked for the second time. At this time, the rotating shaft tube 20 needs to be locked so that the rotating shaft tube 20 cannot continue to rotate. A longitudinal longitudinal slide groove portion 18 is opened on the surface of the clamping main plates 15, and is slidably connected in the longitudinal slide groove portion 18. The pressing slider 23 has a pressing grip rod 19 on its surface that extends outward through the longitudinal slide groove 18. The protruding pressing grip rod 19 facilitates gripping, and a pressing arc plate 24 is fixed at the end of the pressing grip rod 19 in the cavity of the clamping main plate 15, and the pressing arc plate 24 can move longitudinally. At the same time, the moving frame rod 14 is directly above the rotating shaft tube 20, and the arc-shaped inner side of the rotating shaft tube 20 and the outer wall of the rotating shaft tube 20 are respectively provided with corresponding inserts and slots. When the pressing arc plate 24 is attached to the top of the rotating shaft tube 20, the angle of the rotating shaft tube 20 can be restricted by the inserts and slots. On the contrary, when the pressing arc plate 24 is separated from the rotating shaft tube 20, the free rotation of the rotating shaft tube 20 can be realized, and when the end of the pressing arc plate 24 is extended outward The outer edge plate 26 is extended, and a longitudinal spring portion 27 is fixed on the top of the outer edge plate 26, so that the top of the longitudinal spring portion 27 is connected to the inner wall of the cavity of the clamping main plate 15. By pulling up and pressing the gripping rod 19, the lower arc plate 24 can be disengaged, and conversely, the lower arc plate 24 can be pressed on the surface of the rotating shaft tube 20 by the elastic action of the longitudinal spring portion 27. Due to the front and rear movement of the clamping main plate 15, in order to avoid obstruction to the movement of the side pressure rod portion 32, a connecting plate slot 36 is opened on the surface of the pressure plate connecting plate 34, and at the same time, a connecting slider portion 37 is slidably connected in the connecting plate slot 36, and a rotating connecting rod 38 is rotatably connected on the surface of the connecting slider portion 37, and the other end of the rotating connecting rod 38 is rotatably connected to the sliding cross bar portion 39.Through the sliding of the connecting slider 37 in the connecting plate slot 36 and the rotation of the connecting slider 37 and the rotating link 38, the forward and backward movement of the clamping main plate 15 will not affect the lateral movement of the sliding crossbar 39.
