[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely 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, rather than all of the embodiments.

[0020] First embodiment

[0021] A yaw brake disc hanger, comprising a disc 3, the upper side of the disc 3 is fixedly connected to a motor 4, the output shaft of the motor 4 passes through the disc 3, the output shaft of the motor 4 is fixedly connected to a screw rod 5, the screw rod 5 is threadedly connected to a circular plate 6, and the circular plates 6 are respectively connected to corresponding connecting rods 10 through pin hinges;

[0022] The lower side of the disc 3 is fixedly connected to a group of connecting plates 11, and the two ends of each connecting plate 11 are connected to a corresponding group of rocker arms 9 through a pin hinge, and one end of a corresponding group of rocker arms 9 is connected to a corresponding connecting plate 2 8 through a pin hinge, and a group of connecting plates 2 8 is fixedly connected to a corresponding U-shaped clamping plate 7, and one side of the corresponding adjacent rocker arms 9 is connected to one end of the corresponding connecting rod 10 through a pin hinge.

[0023] The upper side of the disc 3 is fixedly connected to the U-shaped block 2 .

[0024] The upper side of the U-shaped block 2 is fixedly connected to the lifting ring 1 .

[0025] Each pair of the swing rods 9 are parallel to each other, and the connecting plate 1 11 is parallel to the connecting plate 2 8 on the same side.

[0026] Working principle: first install the lifting ring 1 and the external crane, so that a group of U-shaped card plates 7 are located at the external yaw brake disc, start the motor 4, the motor 4 drives the screw rod 5 to rotate, the screw rod 5 drives the circular plate 6 to move, the circular plate 6 drives a group of connecting rods 10 to swing, and a group of connecting rods 10 drives a corresponding swing rod 9 to swing. Since a group of swing rods 9 and the connecting plate 1 11 and the connecting plate 2 8 form a parallelogram mechanism, the corresponding group of swing rods 9 drives the corresponding U-shaped card plates 7 to swing through the connecting plate 2 8, so that a group of U-shaped card plates 7 clamp the edge of the external yaw brake disc. At this time, turn off the motor 4 to fix the yaw brake disc, and then start the external crane for lifting.

[0027] Beneficial effect: the lifting ring 1 is installed with the external crane, so that a group of U-shaped card plates 7 are located at the external yaw brake disc, and the motor 4 is started, and finally a corresponding group of swing rods 9 respectively drive the corresponding U-shaped card plates 7 to swing through the connecting plate 2 8, so that a group of U-shaped card plates 7 clamp the edge of the external yaw brake disc, so that the yaw brake disc is fixed, and the external crane is started for lifting at this time. The two swing rods 9 and the connecting plate 1 11 and the connecting plate 2 8 form a parallelogram mechanism, so that the U-shaped card plate 7 is always in a horizontal state during the swing, and the yaw brake disc can be fixed and lifted more stably.
