DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1 The utility model provides a technical solution: it includes a processing table 1, a mounting groove is opened on the processing table 1, two support columns 6 are arranged in the mounting groove, a bidirectional screw rod 4 for driving the support columns 6 to move is rotatably connected in the mounting groove, a mounting plate 10 is rotatably connected to the two support columns 6, a clamping mechanism is arranged on the mounting plate 10, the clamping mechanism includes two clamping plates 21 for clamping the casting, a flipping mechanism for driving the clamping mechanism to flip is arranged between the two mounting plates 10, and the flipping mechanism includes two first bevel gears 15 and a third bevel gear 18 for linking the two mounting plates 10 to rotate.

[0030] See also Figure 2 There are two sliders 2 slidably connected in the installation groove, and the sliders 2 are threadedly connected to the bidirectional screw rod 4. A guide rod 3 is fixedly connected in the installation groove, and the guide rod 3 slides through the slider 2. The two sliders 2 are respectively fixedly connected to the two support columns 6; a first turning handle 5 is rotatably connected to the side wall of the processing table 1, and the first turning handle 5 is coaxially fixed with the bidirectional screw rod 4;

[0031] When in use, rotating the first handle 5 drives the bidirectional screw rod 4 to rotate, and the rotating bidirectional screw rod 4 drives the two sliders 2 and the support column 6 fixed on the slider 2 to move towards each other. When the two support columns 6 are close to each other, the mounting plates 10 on the support columns 6 can be abutted against the two sides of the wind turbine support seat casting, and the distance between the two clamping mechanisms can be controlled according to the size of the wind turbine support seat casting, which has a wide range of applications.

[0032] See also Figure 3 A first cavity and a second cavity are respectively formed in the two sliders 2 and the support column 6. The first bevel gear 15 is rotatably connected in the first cavity, the third bevel gear 18 is rotatably connected in the second cavity, and the third bevel gear 18 is fixedly connected to the mounting plate 10 through a rotating shaft.

[0033] The flip mechanism also includes two rotating rods 17, which are rotatably connected in the second cavity; the flip mechanism also includes a plurality of second bevel gears 16, which are coaxially fixed at both ends of the two rotating rods 17, and the plurality of second bevel gears 16 are respectively meshed with the first bevel gear 15 and the third bevel gear 18; the flip mechanism also includes a cross rod 7, which is rotatably connected in the mounting groove, and the cross rod 7 slides coaxially with the first bevel gear 15. By setting the cross rod 7, after the two first bevel gears 15 move a certain distance, the two first bevel gears 15 can also rotate synchronously;

[0034] When in use, the mounting plate 10 and the third bevel gear 18 are rotated, and the third bevel gear 18 drives the first bevel gear 15 to rotate through the meshing second bevel gear 16 and the rotating rod 17. The rotating first bevel gear 15 drives another first bevel gear 15 to rotate through the coaxial sliding cross rod 7, and then drives the remaining second bevel gears 16, the rotating rod 17 and the third bevel gear 18 to rotate, so that the two mounting plates 10 rotate synchronously, thereby realizing the synchronous rotation of the clamping mechanism on the mounting plate 10, thereby ensuring the stability of the flipping of the wind turbine support base casting. The flipping angles of the two clamping mechanisms are the same, which is also convenient for the operator to clamp and fix the subsequent castings, and the operator does not need to manually adjust the angles of the two mounting plates 10 to be consistent.

[0035] See also Figure 2 and Figure 3A mounting box 8 is fixedly connected to the side wall of the support column 6, a worm wheel 14 and a worm 13 are rotatably connected in the mounting box 8, and the worm wheel 14 meshes with the worm 13, the worm wheel 14 is coaxially fixed with the third bevel gear 18, and a second turning handle 9 is rotatably connected to the outer wall of the mounting box 8, and the second turning handle 9 is coaxially fixed with the worm 13;

[0036] When in use, turning the second turning handle 9 drives the worm 13 to rotate, and the rotating worm 13 drives the third bevel gear 18 and the mounting plate 10 fixedly connected to the third bevel gear 18 to rotate through the meshing worm wheel 14, thereby driving the flipping mechanism to drive the two clamping mechanisms to flip synchronously. It should be noted that there is a self-locking phenomenon between the worm 13 and the worm wheel 14. Rotating the worm 13 can drive the meshing worm wheel 14 to rotate, whereas rotating the worm wheel 14 cannot drive the worm 13 to rotate. This ensures that the wind turbine support base casting can be fixed after flipping a certain angle, and the wind turbine support base casting will not continue to flip due to the shift of the center of gravity, which is convenient for the operator to process the flipped casting.

[0037] See also Figure 4 The clamping mechanism also includes two connecting plates 19 and a fixing plate 20, and the two connecting plates 19 and the fixing plate 20 are fixedly connected to the mounting plate 10; the clamping mechanism also includes two first screws 11 and a second screw 12, the two first screws 11 are respectively threadedly connected to the two fixing plates 20, and the ends of the first screws 11 are rotatably connected to the clamping plates 21, and the two second screws 12 are respectively threadedly connected to the two connecting plates 19; the clamping mechanism also includes two limiting plates 22, the two limiting plates 22 are rotatably connected to the ends of the second screws 12, a slide groove is provided on the clamping plate 21, and the limiting plates 22 slide through the slide groove;

[0038] It should be noted that a limit groove is provided on the side wall of the mounting plate 10, and a limit block is fixedly connected to the clamping plate 21, and the limit block slides in the limit groove, thereby preventing the clamping plate 21 from rotating, thereby achieving the purpose of rotating the first screw 11 to drive the clamping plate 21 to move. When in use, the first screw 11 is rotated to drive the clamping plate 21 to clamp and fix the upper and lower surfaces of the wind turbine support seat casting, and the second screw 12 is rotated to drive the limit plate 22 to limit the front and rear surfaces of the wind turbine support seat casting, so that the clamping mechanism clamps and fixes the two ends of the wind turbine support seat casting, thereby realizing the suspended fixation of the wind turbine support seat casting, so that the operator can subsequently rotate the clamped and fixed wind turbine support seat casting to flip it.

[0039] Working principle: first, turn the first turning handle 5 to drive the bidirectional screw rod 4 to rotate, and the rotating bidirectional screw rod 4 drives the two sliders 2 and the support column 6 fixed on the slider 2 to move in opposite directions. When the two support columns 6 are close to each other, the mounting plates 10 on the support columns 6 can be brought into contact with the two sides of the wind turbine support base casting;

[0040] Then, the first screw 11 is rotated to drive the clamping plate 21 to clamp and fix the upper and lower surfaces of the wind turbine support base casting, and the second screw 12 is rotated to drive the limiting plate 22 to limit the front and rear surfaces of the wind turbine support base casting, so that the clamping mechanism clamps and fixes the two ends of the wind turbine support base casting;

[0041] Finally, the second turning handle 9 is rotated to drive the worm 13 to rotate. The rotating worm 13 drives the third bevel gear 18 and the mounting plate 10 fixedly connected to the third bevel gear 18 to rotate through the meshing worm wheel 14. At the same time, the rotating third bevel gear 18 drives the first bevel gear 15 to rotate through the meshing second bevel gear 16 and the rotating rod 17. The rotating first bevel gear 15 drives another first bevel gear 15 to rotate through the coaxially sliding cross rod 7, and then drives the remaining second bevel gears 16, the rotating rod 17 and the third bevel gear 18 to rotate. The rotating third bevel gear 18 drives the other mounting plate 10 to rotate, thereby realizing the synchronous rotation of the two mounting plates 10 and the clamping mechanism arranged on the mounting plate 10.
