Example 1:
a lifting appliance for mounting a variable-pitch control cabinet 5 of a wind generating set is shown in figures 1 to 4 and comprises a lifting frame 1, a bearing beam 2 and a connecting piece 3, wherein the lifting frame 1 is C-shaped, and a plurality of lifting lugs 6 are arranged on the lifting frame 1. The hanger 1 comprises a flat beam 14 and a vertical beam 15, and a reinforcing beam 16 and/or a triangular reinforcing plate 17 are arranged between the vertical beam 15 and the flat beam 14. The structure serves to stabilize the hanger 1.
The lugs 6 are arranged at the two ends of the top of the hanger 1, the travelling crane drives the lifting appliance to move through the two lugs 6, and the hanger 1 is made of square tubes. The hanger 1 is rotatably connected with a connecting block 4, the connecting block 4 is fixedly connected with a bearing beam 2, and the section steel of the bearing beam 2 is I-shaped steel. As shown in fig. 5, a rotation support 7 is provided between the bearing beam 2 and the hanger 1, and the rotation support 7 includes a rotation sleeve 8 fixedly connected to the hanger 1, a rotation fulcrum 9 inserted in the rotation sleeve 8, and a bearing 10. The structure realizes the rotary connection between the bearing beam 2 and the hanging bracket 1. The bearing 10 is a combined structure of a deep groove ball bearing and a thrust bearing, and the structure has good load capacity in both the axial direction and the radial direction. The rotary support 7 further comprises a bearing 10 and a rotary damper 11 and a lock nut 12. The structure achieves a damping effect. Since the rotary support 7 is used for the rotation of the load-bearing beam 2 relative to the hanger 1, the rotary damper 11 of the bearing 10 can prevent the load-bearing beam 2 from sliding when the load-bearing beam 2 is subjected to an external force.
As shown in fig. 6, the bearing beam 2 is horizontally arranged, the two ends of the bearing beam 2 are respectively provided with a connecting piece 3 for fixing the control cabinet 5, and the bearing beam 2 is rotatably connected with the control cabinet 5 through the connecting pieces 3. The rotating shaft of the connecting piece 3 is arranged along the length direction of the bearing beam 2, the connecting piece 3 is provided with a connecting seat 13 in the radial direction of the rotating shaft, and the connecting seat 13 is fixedly connected with the control cabinet 5 through a fastener. When the control cabinet 5 connected with the connecting base 13 is connected to the connecting base 13, the gravity center and the rotating point of the control cabinet 5 are not on the same vertical line, and the control cabinet 5 leaves the support of the working table surface in the lifting process and rotates around the rotating point until the gravity center and the rotating point are on the same vertical line. The connecting base 13 has a waist hole, and is connected with the control cabinet 5 through the waist hole. The rotating shaft of the connecting piece 3 is sleeved with a bearing 10, a rotary damper 11 and a locking nut 12. The structure plays a role in stabilizing the control cabinet 5, and avoids the situation that the control cabinet 5 swings due to too high hoisting speed and too high rotating speed. The damper 11 is rotated by the bearing 10, and plays a role of canceling inertia. The structure of the bearing 10 rotation damper 11 may be a damping mechanism that is eliminated by using a gear mesh relationship. The bearing 10 rotational damper 11 is a conventional component in the art and will not be described in detail herein.
The hanger 1 is used for connecting a travelling crane, plays the roles of horizontal movement and lifting movement, and drives the control cabinet 5 to move. The spandrel girder 2 is used for driving the switch board 5 to rotate around vertical axis of rotation, changes the gesture of switch board 5, and is concrete, through rotating switch board 5 for the relative gallows 1 of spandrel girder 2 rotates. After the bearing beam 2 rotates 90 degrees, the short edge of the control cabinet 5 faces to the narrow wheel hub inlet, so that the control cabinet 5 can enter the wheel hub inlet more easily. The connecting piece 3 is used for automatically turning the control cabinet 5 when the crane lifts the lifting appliance by utilizing the fact that the connecting position of the bearing beam 2 and the control cabinet 5 and the gravity center of the control cabinet 5 are not on the same vertical line, so that manual operation is omitted, labor is saved, efficiency is improved, and safety is improved.
