[0020] The utility model provides a heavy-duty automatic turning device for loading and unloading materials, comprising a base 1, a support frame 11 fixedly connected to the top of the base 1, two support frames 11 are provided, and the two support frames 11 are fixedly connected by a rotating rod 12, a No. 1 telescopic cylinder 4 is provided on the left side of the rotating rod 12, and a No. 2 telescopic cylinder 5 is provided on the right side of the rotating rod 12, a first turning frame 2 is installed at the output end of the No. 1 telescopic cylinder 4, and a second turning frame 3 is installed at the output end of the No. 2 telescopic cylinder 5, and a positioning component 6 is respectively installed on the top of the first turning frame 2 and the top of the second turning frame 3.

[0021] Furthermore, an extension block 21 is fixedly connected to one side of the first flip frame 2, and two extension blocks 21 are symmetrically arranged. The extension block 21 is rotatably installed on the surface of the rotating rod 12. An extension tube 31 is fixedly connected to one side of the second flip frame 3, and the extension tube 31 is rotatably installed on the surface of the rotating rod 12. The first flip frame 2 and the extension block 21 can rotate around the axis of the rotating rod 12 as a whole, and the second flip frame 3 and the extension tube 31 can rotate around the axis of the rotating rod 12 as a whole.

[0022] Furthermore, two telescopic cylinders 4 are provided, an upper supporting frame 42 is installed at the output end of the telescopic cylinder 4, and a lower supporting frame 41 is installed at the bottom of the telescopic cylinder 4. The upper supporting frame 42 is fixedly installed at the bottom of the first flip frame 2, and the lower supporting frame 41 is fixedly installed at the top of the base 1. The output end of the telescopic cylinder 4 is hinged to the upper supporting frame 42, and the bottom of the telescopic cylinder 4 is hinged to the lower supporting frame 41. Through the extension and shortening of the output end of the telescopic cylinder 4, the first flip frame 2 can be pulled to rotate around the axis of the rotating rod 12, thereby switching the first flip frame 2 back and forth between the horizontal state and the vertical state.

[0023] Furthermore, two telescopic cylinders No. 2 are provided, an upper mounting frame 52 is installed at the output end of the telescopic cylinder No. 2, and a lower mounting frame 51 is installed at the bottom of the telescopic cylinder No. 2. The upper mounting frame 52 is fixedly installed at the bottom of the second flip frame 3, and the lower mounting frame 51 is fixedly installed at the top of the base 1. The output end of the telescopic cylinder No. 2 is hinged to the upper mounting frame 52, and the bottom of the telescopic cylinder No. 2 is hinged to the lower mounting frame 51. By extending and shortening the output end of the telescopic cylinder No. 2, the second flip frame 3 can be pulled to rotate around the axis of the rotating rod 12, thereby switching the second flip frame 3 back and forth between the horizontal state and the vertical state.

[0024] Furthermore, the positioning assembly 6 includes a strip frame 61, a motor 62 and a positioning plate 63. A threaded ring 64 is fixedly installed on the strip frame 61. A threaded rod 65 is fixedly connected to the output end of the motor 62. The surface of the threaded rod 65 is threadedly connected to the inner surface of the threaded ring 64. The positioning plate 63 is rotatably connected to one end of the threaded rod 65. A fixing frame 67 is provided on each side of the motor 62. A guide rod 68 is fixedly installed on the fixing frame 67. An L-shaped rod 66 is fixedly installed on both sides of the motor 62. The L-shaped rod 66 is sleeved on the surface of the guide rod 68. The L-shaped rod 66 and the guide rod 68 form a sliding guide cooperation along the axis direction of the guide rod 68. The strip frame 61 and the fixed frame 67 located at the first turning frame 2 are fixedly connected to the top of the first turning frame 2, and the strip frame 61 and the fixed frame 67 located at the second turning frame 3 are fixedly connected to the top of the second turning frame 3. When the motor 62 drives the threaded rod 65 to rotate around its own axis, since the threaded rod 65 is threadedly connected to the threaded ring 64, the threaded rod 65 rotates and moves synchronously along its own axis. The threaded rod 65 moves and drives the positioning plate 63 to move synchronously in the direction away from the threaded ring 64. At the same time, the L-shaped rods 66 on both sides of the motor 62 slide synchronously along the guide rod 68, and the positioning plate 63 can press the workpiece into position.

[0025] The working principle of the present utility model is as follows: during actual operation, in the initial position, the first turning frame 2 and the second turning frame 3 are both in a horizontal state, the workpiece is located on the top of the second turning frame 3, and the output end of the No. 1 telescopic cylinder 4 gradually extends. During this process, the first turning frame 2 and the extension block 21 rotate as a whole around the axis of the rotating rod 12 until the first turning frame 2 is in a vertical state, and the first turning frame 2 and the second turning frame 3 maintain a vertical distribution. At this time, the first turning frame 2 and the workpiece are in contact with each other.

[0026] The motor 62 drives the threaded rod 65 to rotate around its own axis. The threaded rod 65 moves synchronously along its own axis while rotating. The threaded rod 65 moves and drives the positioning plate 63 to move synchronously in the direction away from the threaded ring 64. The L-shaped rods 66 on both sides of the motor 62 slide synchronously along the guide rod 68. One positioning plate 63 presses the top of the workpiece into position, and the other positioning plate 63 presses one side of the workpiece into position.

[0027] The output end of the No. 1 telescopic cylinder 4 is gradually shortened, and the output end of the No. 2 telescopic cylinder 5 is synchronously gradually extended. During this process, the first flip frame 2 and the second flip frame 3 still maintain a vertical distribution. The first flip frame 2 changes from a vertical state to a horizontal state, and the second flip frame 3 changes from a horizontal state to a vertical state. The workpiece synchronously completes a ninety-degree flip. Afterwards, the motor 62 moves in the opposite direction, and the positioning plate 63 releases the clamping positioning of the workpiece. The output end of the No. 2 telescopic cylinder 5 is shortened, and the second flip frame 3 returns from a vertical state to a horizontal state.
