In the embodiment of the present application, the connecting ropes 32 are steel chains and are fixedly arranged on the side walls of the bottom plates 31. There are multiple connecting ropes 32 between adjacent bottom plates 31 and the connecting ropes 32 are parallel to each other. A sealing cloth is arranged between adjacent bottom plates 31, and the sealing cloth is located below the connecting ropes 32. The width of the sealing cloth is greater than the length of the connecting ropes 32, thereby reducing the possibility of damage to the sealing cloth due to excessive stretching. The sling 3 also includes a suspension beam 33 and a lifting rope 34. The lifting rope 34 is made by winding a plurality of steel wire ropes 23. The lifting rope 34 is arranged on the side walls of the bottom plates 31 at both ends, and the other end of the lifting rope 34 is fixedly arranged on the suspension beam 33. The suspension beam 33 is used to be arranged on the lifting device 2.

[0045] Reference Figure 2 and Figure 3 When hoisting the cover plate 4, the cover plate 4 is placed on the bottom plate 31, and then the hoisting rope 34 on the side of the cover plate 4 is fixed on the suspension beam 33, and then the suspension beam 33 is hung on the wire rope 23 of the winch 22, and then the winch 22 is started. The winch 22 reels the wire rope 23 to hoist the cover plate 4, and the operation is simple and convenient; at the same time, the sealing cloth blocks the gap between adjacent bottom plates 31, thereby improving the safety of hoisting the cover plate 4.

[0046] Reference Figure 4 In order to reduce the possibility of the cover plate 4 sliding on the bottom plate 31 and falling due to the tilt of the cover plate 4 when hoisting, shielding members 5 are provided on both lateral end faces of the bottom plate 31. The shielding members 5 are used to form a shield on the end face of the bottom plate 31 after the cover plate 4 is placed on the bottom plate 31 to limit the cover plate 4; a shield is formed at the end of the cover plate 4 through the shielding member 5, and the cover plate 4 is placed between the bottom plate 31 and the shield, thereby reducing the possibility of the cover plate 4 falling from the bottom plate 31 during the hoisting process, thereby improving the safety of the hoisting of the cover plate 4.

[0047] Reference Figure 4 and Figure 5, the bearing surface of the bottom plate 31 is provided with a removal piece 6, and the removal piece 6 is used to remove the cover plate 4 on the bottom plate 31 after the cover plate 4 is lowered to the ground; when the cover plate 4 is hoisted to the required place, the cover plate 4 falls to the designed place, because the cover plate 4 is pressed on the bottom plate 31, it is difficult to separate the cover plate 4 and the bottom plate 31, which makes it difficult for the sling 3 to quickly carry out the next batch of hoisting operations. Therefore, the removal piece 6 acts on the cover plate 4 to remove the cover plate 4 from the bottom plate 31, and then the cover plate 4 is stacked to the required place, which is convenient for timely removal of the sling 3, thereby improving the hoisting efficiency of the cover plate 4.

[0048] Reference Figure 6 , Figure 7 and Figure 8 In the embodiment of the present application, the removal member 6 includes a load-bearing wheel 61 arranged on the bottom plate 31, the load-bearing wheel 61 is rotatably arranged on the bottom plate 31, the rotation axis of the load-bearing wheel 61 is parallel to the width direction of the bottom plate 31, a plurality of load-bearing wheels 61 are arranged and are evenly arranged along the length direction of the bottom plate 31, a mounting groove is opened on the bearing surface of the bottom plate 31, the load-bearing wheel 61 is located in the mounting groove, after the load-bearing wheel 61 is located in the mounting groove, the top surface of the load-bearing wheel 61 is located below the receiving surface of the bottom plate 31, the load-bearing wheel 61 is slidably arranged in the mounting groove, and the load-bearing wheel 61 slides along the depth direction of the mounting groove, and the removal member 6 also includes a driving member for driving the load-bearing wheel 61 to slide and carry the cover plate 4;

The driving member includes an air pump arranged on the bottom plate 31, and the air pump is connected to the air inlet of the bearing airbag 63.

[0050] When the cover plate 4 is hoisted, the load-bearing wheel 61 is received in the installation groove, so that the cover plate 4 is supported on the base plate 31, and the contact surface between the cover plate 4 and the base plate 31 is increased, thereby reducing the possibility of the cover plate 4 sliding on the base plate 31, thereby improving the safety of the hoisting of the cover plate 4; when the cover plate 4 is hoisted and transported to the required position, the air pump is started, and the air pump injects compressed gas into the load-bearing airbag 63. The volume of the load-bearing airbag 63 increases and lifts the load-bearing plate 62. The load-bearing plate 62 moves out of the installation groove and lifts the cover plate 4, thereby separating the cover plate 4 from the base plate 31, and then pushing the cover plate 4 to move on the load-bearing wheel 61, which facilitates the separation of the cover plate 4 from the sling 3, thereby facilitating the removal of the cover plate 4.

Further, a driving motor 67 is provided in the installation notch 8, and the driving roller 66 is coaxially arranged on the output shaft of the driving motor 67. After the load-bearing plate 62 drives the load-bearing wheel 61 to abut the cover plate 4, the drive motor 67 is started, and the drive motor 67 drives the drive roller 66 to run. The running of the drive roller 66 drives the drive belt 65 to run. The running of the drive belt 65 drives the load-bearing wheel 61 to rotate. The rotation of the load-bearing wheel 61 drives the cover plate 4 to move, thereby facilitating the cover plate 4 to be removed from the sling 3.

[0063] When the cover plate 4 is hoisted, the hoisting device 3 is first placed on the ground, and then the bottom plates 31 on both sides are pulled to straighten the connecting ropes 32, and then the cover plate 4 to be hoisted is placed on the bottom plate 31, and then the mounting plate 53 is driven to slide out of the bottom plate 31 by the slide plate 52, and then the shielding net 51 is connected, and the shielding net 51 forms a shield at the end of the cover plate 4, so that the cover plate 4 is placed between the bottom plate 31 and the shielding, thereby reducing the possibility of the cover plate 4 falling off the bottom plate 31 during the hoisting process;

[0064] Then, the hoisting rope 34 is connected to the suspension beam 33, and then the suspension beam 33 is connected to the hoisting machine 22, and then the cover plate 4 is hoisted by the hoisting machine 22. At this time, the moving motor 26 is started, and the moving motor 26 adjusts the position of the mounting seat 20, and then the position of the crimping rod 18 is adjusted by the adjusting motor 24, so that the crimping plate 19 is crimped at the edge of the cover plate 4;

[0065] When the cover plate 4 is hoisted to the required location and falls to the designed location, the air pump is started to inject compressed gas into the load-bearing airbag 63. The volume of the load-bearing airbag 63 increases and lifts the load-bearing plate 62. The load-bearing plate 62 moves out of the installation groove and lifts the cover plate 4, thereby separating the cover plate 4 from the bottom plate 31, and then pushing the cover plate 4 to move on the load-bearing wheel 61, which facilitates the separation of the cover plate 4 from the sling 3, thereby facilitating the removal of the cover plate 4 and facilitating the next hoisting of the sling 3.
