DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following details the content of the present utility model in conjunction with the description of the drawings and embodiments:

[0019] As Figures 1 to 4The figure shows a schematic diagram of an embodiment of a hoisting and transportation frame for an assembled composite slab provided by the present utility model, including a support platform 1. At the four corners of the top of the support platform 1, support columns 2 are provided. A number of annular connection grooves 3 are evenly distributed up and down on the surface of the support column 2. An activity ring 4 is rotatably connected inside the annular connection groove 3. A fixed ring 5 is fixedly sleeved on the top surface of the activity ring 4. A support block 6 is fixedly arranged on one side surface of the fixed ring 5. A lifting ring 7 is arranged at the top of the support column 2. Two extension columns 8 are arranged on both sides of the support platform 1. A rotating shaft 9 is movably arranged between the two extension columns 8 on the same side. A clamping rod 10 is vertically connected to the middle of the surface of the rotating shaft 9. The other end of the clamping rod 10 is provided with a fixed rod 11 parallel to the rotating shaft 9. Connection rings 12 are arranged at both ends of the fixed rod 11. A connection bolt 13 is movably connected inside the connection ring 12. A fixed column 14 is arranged on one side of the top of the support column 2 close to the extension column 8. A fixed screw hole 15 matched with the connection bolt 13 is arranged at one end of the fixed column 14.

[0020] Further, a U-shaped clamping block 16 is movably connected to one side of the fixed rod 11. A fixed groove 17 is opened at the closed end of the U-shaped clamping block 16. First screw holes 18 are arranged on both sides of the fixed groove 17. A number of second screw holes 19 are evenly distributed up and down on the surface of the fixed rod 11. The fixed groove 17 is matched with the surface of the fixed rod 11. A first bolt 20 is commonly connected between the first screw hole 18 and the second screw hole 19.

[0021] After the composite slab is placed on the top of the support platform 1, the opening of the U-shaped clamping block 16 is clamped on the side surface of the composite slab. Then, the fixed rod 11 is rotated through the rotating shaft 9 to make the fixed rod 11 stand up. The U-shaped clamping block 16 is slid along the side surface of the composite slab to the fixed rod 11. The second screw hole 19 and the first screw hole 18 are connected by the first bolt 20 to fixedly connect the U-shaped clamping block 16 and the fixed rod 11. Then, the connection bolt 13 and the fixed screw hole 15 are connected and fixed, so that the fixed rod 11 and the clamping rod 10 are fixedly connected, thereby fixing and limiting both sides of the composite slab to prevent the composite slab from slipping and vibrating.

[0022] A first reinforcing block 51 is commonly connected between the fixed ring 5 and the activity ring 4. A second reinforcing block 52 is commonly connected between the support block 6 and the activity ring 4. The supporting ability of the support block 6 can be enhanced through the first reinforcing block 51 and the second reinforcing block 52, so that the support block 6 is more stable when supporting the composite slab.

[0023] On one side inside the annular connection groove 3, there is a positioning screw hole 31. On the side of the movable ring 4 away from the support block 6, there is an engagement hole 32. The engagement hole 32 and the positioning screw hole 31 are jointly connected by a positioning bolt 33. By connecting the engagement hole 32 and the positioning screw hole 31 with the positioning bolt 33, the movable ring 4 is fixed to the annular connection groove 3, and the support block 6 is fixed towards the center of the support table 1, playing a role in supporting the laminated board. When the positioning bolt 33 is taken out from the engagement hole 32 and the positioning screw hole 31, at this time, the movable ring 4 can rotate inside the annular connection groove 3, so that the support block 6 rotates towards the side away from the support table 1, facilitating the unloading of the laminated board at the bottom layer.

[0024] On the surface of the movable ring 4, there is a positioning line 34, and the positioning line is opposite to the engagement hole 32. On the surface of the support column 2, there is a positioning arrow 35, and the positioning arrow 35 is opposite to the positioning screw hole 31. The provided positioning arrow 35 and the positioning line 34 can enable the operator to more conveniently align the engagement hole 32 with the positioning screw hole 31.

[0025] The positioning arrow 35 matches the positioning line 34. The provided positioning arrow 35 and the positioning line 34 can enable the operator to more conveniently align the engagement hole 32 with the positioning screw hole 31, facilitating the connection of the engagement hole 32 and the positioning screw hole 31 by the positioning bolt 33.

[0026] The opening size of the U-shaped clamping block 16 matches the thickness of the laminated board.

[0027] The fixed screw hole 15 is in threaded connection with the connecting bolt 13.

[0028] Specifically, when loading the laminated board, by placing the first-layer laminated board on the top of the support table 1, and then rotating the four support blocks 6 at the top layer around the annular connection groove 3 through the movable ring 4 to align the positioning arrow 35 with the positioning line 34, so that the support blocks 6 rotate towards the central side of the support table 1. After all four support blocks 6 face the central side, place the second-layer laminated board on the top of the four support blocks 6, and repeat this process for stacking. After the stacking is completed, clamp the opening of the U-shaped clamping block 16 on the side surface of the laminated board, then rotate the fixed rod 11 through the rotating shaft 9 to make the fixed rod 11 stand upright. Slide the U-shaped clamping block 16 along the side surface of the laminated board to the fixed rod 11. Connect the second screw hole 19 and the first screw hole 18 with the first bolt 20 to fixedly connect the U-shaped clamping block 16 and the fixed rod 11. Then connect the connecting bolt 13 and the fixed screw hole 15 to fix the fixed rod 11 and the clamping rod 10, thereby fixing and limiting both sides of the laminated board to prevent the laminated board from slipping and vibrating. Lift the laminated boards on the top side of all support tables 1 through the lifting ring 7;

[0029] When unloading the laminated slab, by detaching the connecting bolt 13 from the inside of the fixed screw hole 15, removing the first bolt 20 from the inside of the second screw hole 19 and the first screw hole 18, separating the U-shaped clamping block 16 from the fixed rod 11, unloading the first-layer laminated slab at the top, and then when removing the positioning bolt 33 of the top movable ring 4 from the inside of the connection hole 32 and the positioning screw hole 31, at this time the top movable ring 4 can rotate within the annular connection groove 3, so that its support block 6 rotates towards the side away from the support table 1, and the laminated slab at its bottom layer is unloaded.
