Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-4 This utility model provides a technical solution: a safety protection door for a mine cage, comprising a cage body 1, an upper cage door 3, and a lower cage door 4. An upper mounting shaft 2 is provided on the upper part of the cage body 1, and a lower mounting shaft 5 is provided on the lower part of the cage body 1. An inner plate 101 is provided inside the cage body 1. A fixing plate 6 and a mounting plate 8 are provided between the inner plate 101 and the inner wall of the cage body 1. An electric cylinder 7 is provided on the fixing plate 6, and a connecting plate 9 is provided at the top of the electric cylinder 7. A first connecting rod 10 is connected to the lower part of the mounting plate 8, and a first sector plate 11 is provided at the top of the first connecting rod 10. A first support rod 12 is provided on the upper part of the first sector plate 11, and a positioning block 13 is provided on the right end of the first support rod 12. A second connecting rod 14 is connected to the upper part of the mounting plate 8, and a second sector plate 15 is provided below the second connecting rod 14. A second support rod 16 is provided below the second sector plate 15, and a second positioning block 17 is provided on the right end of the second support rod 16. When the upper cage door 3 and the lower cage door 4 are opened, the electric cylinder 7 (any commercially available model of electric cylinder 7 can be used) is activated. The electric cylinder 7 pushes the connecting rod 9 to move upward, and the connecting rod 9 drives the mounting plate 8 to rotate. Plate 9 pushes the first connecting rod 10 to push the first sector plate 11 to rotate upward. During the rotation of the first sector plate 11, it pushes the first support rod 12, causing the first support rod 12 to push the first positioning block 13. The first positioning block 13 is fixedly connected to the upper cage door 3. The first positioning block 13 pushes the upper cage door 3, which is mounted on the upper mounting shaft 2. The upper cage door 3 is opened by rotating through the upper mounting shaft 2. At the same time, during the rotation of the mounting plate 8, the upper part of the mounting plate 8 pushes the second connecting rod 14 downward, and the second connecting rod 14 pushes the second sector plate 11 to rotate upward. When the second sector plate 15 rotates, it can push the second support rod 16, which in turn pushes the second positioning block 17. The second positioning block 17 then pushes the lower cage door 4. The lower cage door 4 is mounted on the lower mounting shaft 5. The lower cage door 4 opens by rotating downwards through the lower mounting shaft 5, thereby opening the upper cage door 3 and the lower cage door 4 simultaneously. After the lower cage door 4 opens, one end contacts the ground, forming a temporary passage that facilitates the entry of workers or trolleys into the cage, avoiding the problem of inconvenience caused by the gap between the cage body 1 and the ground.
[0022] Reference example: the inner plate 101 is provided with a sleeve 18, the bottom of the sleeve 18 is provided with a through slot 19, the sleeve 18 is provided with a positioning rod 20, the bottom of the positioning rod 20 is provided with a push rod 21, the right end of the positioning rod 20 is provided with a spring 22, the top of the upper installation shaft 2 is provided with a positioning port 201, when the upper cage door 3 is opened upward through the upper installation shaft 2, after the upper cage door 3 is rotated by ninety degrees, the positioning port 201 provided on the upper installation shaft 2 is rotated to the left side of the positioning rod 20, the spring 22 pushes the positioning rod 20 to move leftwards, and the positioning port 201 is clamped to fix the upper installation shaft 2, so as to fix the upper cage door 3, so that the upper cage door 3 cannot be accidentally dropped when personnel enters or exits the cage body 1, and the safety of the staff passing through is improved, the upper cage door 2 and the lower cage door 3 are closed, the push rod 21 is pushed rightwards, the push rod 21 drives the positioning rod 20 to disengage from the positioning port 201, and then the electric cylinder is started, so that the upper cage door 2 and the lower cage door 3 are completely closed.
