DETAILED DESCRIPTION

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Reference Figure 1-5 The utility model provides a technical solution: a hoisting mechanism for casting a mold of a wind power base, comprising a hoisting frame 1, a hoisting box 2 is fixedly installed at the bottom of the hoisting frame 1, a limiting mechanism comprises a driven plate 3, a limiting shell 4, a lifting rod 5, a slide 6 and a slide 7, the driven plate 3 is rotatably mounted inside the hoisting box 2, the limiting shell 4 is fixedly mounted at the bottom of the driven plate 3, the lifting rod 5 is slidably sleeved inside the limiting shell 4, the slide 6 is opened at the bottom of the driven plate 3, the slide 7 is slidably sleeved inside the slide 6, the rotating mechanism is arranged inside the hoisting box 2, and is used to adjust the mold direction. In the direction, by setting a limit mechanism, the lifting rod 5 is moved upward, and at the same time, the slide rod 7 is moved in the direction away from the central axis of the driven plate 3 through the cooperation of the slide groove 6, so that the multiple slide rods 7 are away from each other. At this time, the mold is transported between the multiple slide rods 7 by external equipment such as a forklift, and the mold is located between the horizontal end of the slide rod 7 and the horizontal end of the lifting rod 5. The multiple slide rods 7 and the lifting rod 5 are reset to clamp the mold. Compared with the existing technology, not only the mold is limited at the horizontal end, but also a limit is added at the vertical end, which makes the mold more stable during the lifting process and not easy to fall.

[0036] Reference Figure 1-5 , the rotating mechanism includes a driving plate 8, a driving shaft 9 and a stroke groove 10. The driving plate 8 is rotatably installed inside the lifting box 2, and the driving shaft 9 is fixedly installed at the bottom of the driving plate 8. The stroke groove 10 is opened at the top of the driven plate 3, and the driving shaft 9 is slidably sleeved inside the stroke groove 10. By setting a rotating mechanism, the mold is lifted by the crane and the lifting ring on the lifting frame 1, and the driving plate 8 is rotated. The center of the circle formed by the multiple stroke grooves 10 coincides with the center of the driving plate 8 and the driven plate 3, so that the driving plate 8 drives the driving shaft 9 to rotate in the stroke groove 10, so that the driving plate 8 drives the driven plate 3 to rotate. Since the mold is limited between the slide bar 7 and the lifting rod 5 at this time, the mold rotates at the same time, so that the overlap between the molds can be adjusted, which is convenient for the staff to perform mold closing operation;

[0037] Reference Figure 1-5The lifting rod 5 and the sliding rod 7 are both L-shaped, with the horizontal end of the sliding rod 7 located below the horizontal end of the lifting rod 5. A fixing block 11 is fixedly installed on the opposite side of the lifting rod 5 and the sliding rod 7. A rotating rod 12 is rotatably installed between the two fixing blocks 11. By setting the fixing block 11 and rotating, when the lifting rod 5 moves upward, the fixing block 11 on the lifting rod 5 is driven to move upward. Through the cooperation of the rotating rod 12, the sliding rod 7 moves inside the sliding groove 6, so that the lifting rod 5 can provide driving force for the sliding rod 7 when it moves, so that the sliding rod 7 moves automatically.

[0038] Reference Figure 1-5 The top of the slide bar 7 is fixedly installed with a first limit block 13, and the first limit block 13 passes through the top of the driven plate 3. The cross-section of the first limit block 13 is set to a T-shape, and the inner wall of the slide groove 6 is provided with a second limit groove 14. The second limit block 15 is slidably installed inside the second limit groove 14, and the second limit block 15 is fixedly connected to the first limit block 13. The bottom of the first limit block 13 is rotatably installed with a roller 16, and the bottom of the roller 16 contacts the top of the driven plate 3. By setting the first limit block 13 and the second limit block 15, the moving direction of the slide bar 7 is restricted, so that the rotating rod 12 can drive the slide bar 7 to move along the slide groove 6, and the setting of the roller 16 makes the friction between the first limit block 13 and the driven plate 3 change from sliding friction to rolling friction, so that the movement of the slide bar 7 is smoother.

[0039] Reference Figure 1-5 A gear 17 is rotatably mounted on the top of the driven plate 3, and a threaded rod 18 is fixedly mounted on the bottom of the gear 17. The threaded rod 18 is sleeved inside the lifting rod 5, and the threaded rod 18 and the lifting rod 5 are threadedly connected. By setting the threaded rod 18, when the gear 17 rotates, the threaded rod 18 is driven to rotate. Through the threaded connection between the threaded rod 18 and the lifting rod 5, and the cooperation of the limit shell 4, the lifting rod 5 is moved up or down;

[0040] Reference Figure 1-5, a gear ring 19 is fixedly installed at the bottom of the driving plate 8, and the gear ring 19 is meshed with the gear 17. A support frame 20 is fixedly installed on the top of the lifting box 2, and a motor 21 is fixedly installed on the top of the support frame 20. The output end of the motor 21 is fixedly connected to the top of the driving plate 8. By setting the gear ring 19, in the initial state, the driving shaft 9 is located at one end point of the travel groove 10. The motor 21 is started to drive the driving plate 8 to rotate, thereby rotating the gear ring 19. The gear 17 is rotated through the meshing connection between the gear ring 19 and the gear 17, thereby moving the lifting rod 5 upward and moving the sliding rod 7 to the side away from the central axis of the driven plate 3. At the same time, the driving shaft 9 moves inside the travel groove 10, and the driving shaft 9 does not squeeze the inner wall of the travel groove 10. The driving plate 8 cannot drive the driven plate 3 to rotate. After the mold is transported to between the horizontal end of the slide bar 7 and the horizontal end of the lifting rod 5, the motor 21 is started in the reverse direction to drive the slide bar 7 and the lifting rod 5 back to their original positions, limit the mold, and at the same time make the driving shaft 9 return to its original position. When the mold needs to be rotated, the motor 21 is started again to make the driving plate 8 drive the driving shaft 9 to squeeze the inner wall of the stroke groove 10, so that the driving plate 8 drives the driven plate 3 to rotate. At the same time, since the gear 17 is installed on the driven plate 3 and the ring gear 19 is installed on the driving plate 8, the centers of the gear 17, the ring gear 19, the driving plate 8 and the driven plate 3 coincide with each other, so that when the driving plate 8 and the driven plate 3 rotate at the same time and in the same direction, the gear 17 and the ring gear 19 are relatively stationary, and the limiting mechanism remains in a clamping state.

[0041] Specifically, the working process or working principle of the wind power base casting mold lifting mechanism is as follows: when in use, the motor 21 is started to drive the driving plate 8 to rotate, thereby rotating the gear ring 19, and the gear 17 is meshed with the gear ring 19, so that the gear 17 rotates, driving the threaded rod 18 to rotate, and the threaded connection between the threaded rod 18 and the lifting rod 5, as well as the cooperation of the limit shell 4, makes the lifting rod 5 move upward, driving the fixed block 11 on the lifting rod 5 to move upward, and through the cooperation of the rotating rod 12, the sliding rod 7 moves inside the sliding groove 6, so that the sliding rod 7 moves in the direction away from the central axis of the driven plate 3, so that multiple sliding rods 7 move away from each other, and at the same time the driving shaft 9 moves inside the travel groove 10, and the driving shaft 9 does not squeeze the inner wall of the travel groove 10, and the driving plate 8 cannot drive the driven plate 3 to rotate. External equipment such as a forklift transports the mold between multiple slide bars 7, and places the mold between the horizontal end of the slide bar 7 and the horizontal end of the lifting rod 5. The motor 21 is started in the reverse direction to drive the slide bar 7 and the lifting rod 5 back to their original positions, limiting the mold. At the same time, the drive shaft 9 is returned to its original position, and the mold is lifted by the crane and the lifting ring on the lifting frame 1. When the mold needs to be rotated, the motor 21 is started again to make the drive plate 8 drive the drive shaft 9 to squeeze the inner wall of the stroke groove 10, so that the drive plate 8 drives the driven plate 3 to rotate. At the same time, since the gear 17 is installed on the driven plate 3 and the ring gear 19 is installed on the drive plate 8, the centers of the gear 17, ring gear 19, drive plate 8 and driven plate 3 coincide with each other, so that when the drive plate 8 and the driven plate 3 rotate in the same direction at the same time, the gear 17 and the ring gear 19 are relatively stationary, and the limiting mechanism remains in a clamping state.
