The output end of the second servo motor 14 is connected to one end of the screw 15. A screw sleeve 16 is provided on the outer wall of the screw 15. A connecting block 17 is installed on the top of the screw sleeve 16. The top of the connecting block 17 is connected to the bottom end of the movable plate 4. When in use, the second servo motor 14 is started to drive the screw 15 to rotate, thereby driving the screw sleeve 16 to move, and then with the cooperation of the limiting slot 18, the limiting block 19 and the moving wheel 20, the movable plate 4 is moved by The connecting block 17 drives the movable plate 4 to move, moves the movable plate 4 out from above the placement plate 1, and then places one end of the steel truss floor decking on the top of the movable plate 4, and then starts the second servo motor 14 to reverse it, driving the movable plate 4 to return to its original position. At this time, slowly place the other end of the steel truss floor decking on the top of the movable plate 4 to complete the storage of the steel truss floor decking. When it needs to be taken, start the second servo motor 14 to reverse it, move the movable plate 4 out from above the placement plate 1, and then connect the middle position of the steel truss floor decking to the crane for hoisting, so that the steel truss floor decking on the lower movable plate 4 is more convenient and quick to take, thereby greatly improving the convenience of the positioning frame when in use.

[0023] The limiting structure includes a limiting groove 18, a limiting block 19 and a moving wheel 20. The limiting groove 18 is opened on both sides of the placement plate 1. The limiting block 19 is arranged inside the limiting groove 18. The top of the limiting block 19 is connected to the bottom end of the movable plate 4. The moving wheel 20 is installed below the inner side of the limiting block 19. A plurality of limiting blocks 19 are arranged below the movable plate 4. The plurality of limiting blocks 19 are distributed at equal intervals. When in use, the limiting groove 18, the limiting block 19 and the moving wheel 20 cooperate with each other to limit the movable plate 4 when it moves, so that the movable plate 4 is more stable when it moves.

[0024] The positioning mechanism includes a vertical plate 5, a clamping plate 6, a mounting cavity 7, a first servo motor 8, a threaded rod 9, a threaded sleeve 10, a movable cavity 11 and a guide structure. The vertical plate 5 is installed at both ends of the top of the placement plate 1. The clamping plate 6 is installed on the inner side of the vertical plate 5. The mounting cavity 7 is installed on the outer side of the vertical plate 5. The first servo motor 8 is installed at one end of the mounting cavity 7. The threaded rod 9 is installed inside the mounting cavity 7. The output end of the first servo motor 8 is connected to one end of the threaded rod 9. The outer wall of the threaded rod 9 is provided with a threaded sleeve 10. The outer wall of the threaded sleeve 10 is fixedly installed. There is an active cavity 11, one end of which extends to the inner side of the vertical plate 5, and one end of which is connected to one end of the clamping plate 6. When in use, the first servo motor 8 is started to drive the threaded rod 9 to rotate, thereby driving the threaded sleeve 10 to move. Therefore, under the limitation of the guide groove 12 and the guide block 13, the threaded sleeve 10 is used to drive the active cavity 11 to move, thereby driving the two clamping plates 6 to move, and the clamping plates 6 are used to clamp and position the steel truss floor decking, so that the steel truss floor decking is more stable when stored, thereby greatly improving the safety of the positioning frame when in use.

[0025] The guide structure includes a guide groove 12 and a guide block 13. The guide groove 12 is opened on both sides of the installation cavity 7. The guide block 13 is arranged inside the guide groove 12. One end of the guide block 13 is connected to one side of the active cavity 11. The outer diameter of the guide groove 12 is larger than the inner diameter of the guide block 13. A sliding structure is formed between the guide groove 12 and the guide block 13. When in use, the active cavity 11 can be guided by the mutual cooperation between the guide groove 12 and the guide block 13, so that the active cavity 11 is more stable when moving.

[0026] Working principle: the staff first moves the positioning frame to the appropriate position, and then starts the second servo motor 14 to drive the screw 15 to rotate, thereby driving the screw sleeve 16 to move, and then with the cooperation of the limit groove 18, the limit block 19 and the moving wheel 20, the connecting block 17 is used to drive the movable plate 4 to move, and the movable plate 4 is moved out from above the placement plate 1, and then one end of the steel truss floor deck is placed above the movable plate 4, and then the second servo motor 14 is started to reverse it, driving the movable plate 4 to return to its original position, and then slowly place the other end of the steel truss floor deck above the movable plate 4 to complete the storage of the steel truss floor deck, and then start the second servo motor 14. A servo motor 8 drives the threaded rod 9 to rotate, and then drives the threaded sleeve 10 to move. Therefore, under the limitation of the guide groove 12 and the guide block 13, the threaded sleeve 10 is used to drive the movable cavity 11 to move, and then drives the two clamps 6 to move. The clamps 6 are used to clamp and position the steel truss floor deck. When the steel truss floor deck needs to be taken, the first servo motor 8 is started to reverse it, driving the clamps 6 to move, and the second servo motor 14 is started to reverse it, and the movable plate 4 is moved out from above the placement plate 1, and then the middle position of the steel truss floor deck is connected to the crane, and it is hoisted to complete the convenient use of the steel truss floor deck.
