An upper cover plate is placed in the first positioning groove 7 , and the first positioning groove 7 matches with the second positioning groove 10 .

[0020] A clamping assembly for clamping the upper cover is provided on both sides of the first positioning groove 7. The clamping assembly includes two clamping plates 8, which are located on both sides of the first positioning groove 7, and the two clamping plates 8 correspond to the corresponding slots 11. Second slide grooves 9 are provided on both sides of the first positioning groove 7, and the clamping plates 8 are slidably connected in the corresponding second slide grooves 9. An electric push rod 16 is fixedly connected to the inner wall of each second slide groove 9, and the telescopic shaft of the electric push rod 16 is fixedly connected to one side of the corresponding clamping plate 8.

[0021] A third slide groove 12 is provided on both sides of the bracket 2, and a rotating shaft 13 is slidably connected up and down in each third slide groove 12, and each rotating shaft 13 is rotatably connected in the corresponding slider 4 and is respectively fixedly connected to the two ends of the rotating plate 6. A gear 14 is fixedly sleeved on the outer circumferential surface of the outer end of each rotating shaft 13, and each gear 14 is meshed with a rack 15, and the two racks 15 are respectively fixedly connected to the two sides of the bracket 2.

[0022] Each slider 4 is provided with a locking assembly for preventing the rotating shaft 13 and the rotating plate 6 from rotating. The locking assembly includes a limit ring 17, which has two limit rings 17 and is respectively fixedly sleeved on the outer circumference of the rotating shaft 13. The two limit rings 17 are respectively rotatably connected in the corresponding slider 4. Each slider 4 is provided with two limit grooves, which are respectively located on both sides of the outer circumference of the limit ring 17. A clamping block 18 is slidably connected in each limit groove. One end face of the clamping block 18 that matches the limit ring 17 is an arc surface. The limit ring 17 is provided with an arc groove that matches the arc surface. A spring 19 is fixedly connected between the clamping block 18 and the inner wall of the limit groove.

[0023] The upper end of the bracket 2 is fixedly connected with a controller, and the controller is electrically connected to the cylinder 3 and the electric push rod 16.

[0024] Working principle: In summary, in the initial state, the telescopic shafts of the two cylinders 3 are in a retracted state, the top surface of the rotating plate 6 faces upward, the clamping assembly is in a relaxed state, and the clamping block 18 cooperates with the limit ring 17.

[0025] When using the device, the personnel place the upper cover plate into the first positioning groove 7 and the lower cover plate into the second positioning groove 10. Then the personnel open the two electric push rods 16 through the control panel, and the two electric push rods 16 push the two clamping plates 8 closer to each other, thereby clamping and fixing the upper cover plate in the first positioning groove 7.

[0026] After the upper cover is fixed, the electric push rod 16 is closed by the controller, and then the two cylinders 3 are started, and the telescopic shafts of the cylinders 3 are extended to push the two slide blocks 4 to move downward in the first slide groove 5.

[0027] During the downward movement of the two sliders 4, the sliders 4 drive the two rotating shafts 13 to move downward in the third slide slots 12, and the rotating shaft 13 drives the gear 14 to move downward, and the gear 14 meshes with the rack 15, so that during the downward movement of the gear 14, the gear 14 rotates. The gear 14 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the rotating plate 6 to rotate.

[0028] At the same time, the rotating shaft 13 drives the limiting ring 17 to rotate, and the arc surface of the clamping block 18 slides relative to the arc groove on the limiting ring 17. The limiting ring 17 pushes the two clamping blocks 18 away from each other, so that the arc surfaces of the two clamping blocks 18 match the outer circumferential surface of the limiting ring 17, and the clamping block 18 compresses the two springs 19.

[0029] When the rotating plate 6 rotates 180°, the gear 14 disengages from the rack 15, the rotating shaft 13 stops rotating, and the arc groove of the limiting ring 17 rotates back to the position of the clamping block 18. The two springs 19 push the arc surface of the clamping block 18 into the arc groove of the limiting ring 17, thereby fixing the limiting ring 17, the rotating shaft 13 and the rotating plate 6 to prevent the rotating plate 6 from rotating.

[0030] The telescopic shafts of the two cylinders 3 continue to extend, and finally the rotating plate 6 contacts the bottom plate 1, and then the personnel close the two cylinders 3 through the controller. At this time, the two clamping plates 8 are inserted into the corresponding slots 11, and the first positioning groove 7 and the second positioning groove 10 are matched, and finally the upper cover plate and the lower cover plate are pressed together.

[0031] Then the personnel activate the two electric push rods 16 through the controller, so that the telescopic shafts of the two electric push rods 16 shrink, thereby driving the two clamps 8 to move away from each other, so that the clamps 8 release the upper cover. Then the personnel close the electric push rods 16 through the controller, activate the two cylinders 3, and the telescopic shafts of the two cylinders 3 shrink, driving the slider 4 and the rotating plate 6 to move upward. After the rotating plate 6 is separated from the bottom plate 1, the personnel take out the upper cover and the lower cover that have been pressed together in the second positioning groove 10.

[0032] When the slide block 4 rises to a certain height, the gear 14 meshes with the rack 15 again, and the slide block 4 continues to move upward, causing the two gears 14 to rotate. The gear 14 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the rotating plate 6 to rotate 180 degrees. The slide block 4 rises to the uppermost end of the first chute 5, and then the personnel closes the two cylinders 3 through the controller.

[0033] When the rotating shaft 13 rotates, it drives the two limiting rings 17 to rotate, and the limiting rings 17 drive the two clamping blocks 18 to move away from each other. After the limiting ring 17 rotates 180°, the arc surface of the clamping block 18 matches the outer circumferential surface of the limiting ring 17 again.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
