[0033] S2, one end of the guide chain 4 is used to connect the wall panel body 2, and the other end of the guide chain 4 is manually pulled to position the wall panel body 2 by pulling back and forth, and the hoisting device 1 is manually raised and lowered according to the height between different structural beams and the top plate structural beam;

[0034] S3. A mobile vehicle 3 is provided at the bottom of the wall panel body 2 to support and move the wall panel body 2, so as to facilitate supporting the wall panel body 2, reduce the physical exertion of personnel, and facilitate the transportation of the wall panel body 2;

[0035] Specifically, after the wall panel body 2 is transported to the bottom of the lifting point by the mobile vehicle 3, the wall panel body 2 is lifted by the lifting device 1, and one end of the guide chain 4 is connected to the top of the wall panel body 2. By pulling the other end of the guide chain 4, the position and angle of the wall panel body 2 are adjusted to facilitate subsequent installation.

[0036] The hoisting device 1 comprises two steel-shaped load-bearing brackets 5, a long rod 12 is installed between the top ends of the two steel-shaped load-bearing brackets 5, a sliding sleeve 13 is provided on the outer sliding sleeve of the long rod 12, a hanging ear is provided at the bottom end of the sliding sleeve 13, and the guide chain 4 is suspended and installed on the hanging ear;

[0037] The steel load-bearing support 5 includes two vertical rods 14, a horizontal rod 15 is fixed between the top ends of the two vertical rods 14, and a rectangular sleeve 16 is slidably sleeved between the outer sides of the two vertical rods 14, a connecting rod 18 is fixed between the opposite sides of the two rectangular sleeves 16, the top end of the horizontal rod 15 is supported on the bottom end of the top plate structural beam, and the connecting rod 18 is supported on the top end of the structural beam.

[0038] A reinforcing mechanism is provided at the top of the two cross bars 15, and the reinforcing mechanism includes a square wood 6, which is fixed to the top of the cross bar 15, and U-shaped seats 7 are fixed on both sides of the bottom of the square wood 6. The two U-shaped seats 7 are respectively provided on both sides of the cross bar 15, and anti-dumping columns 8 are fixed at the bottom of the two U-shaped seats 7.

[0039] The bottom end of the anti-dumping column 8 is telescopically provided with a telescopic rod 9, the bottom end of the telescopic rod 9 is fixed with a support plate 10, the top end of the square wood 6 is supported on the bottom end of the top plate structural beam, and the support plate 10 is supported on the top end of the structural beam.

[0040] In the actual operation of the present invention, two steel-shaped load-bearing brackets 5 are installed depending on the spacing between the structural beams and the top plate structural beams at the installation site, so that the hoisting device 1 can be fixed, and the guide chain 4 can be installed on the sliding sleeve 13 outside the long rod 12, and the guide chain 4 can be used to hoist the wall panel body 2, and adjust the installation angle and position;

[0041] The specific installation method is: a person manually pulls the other end of the guide chain 4 to make the wall panel body 2 reach the required height. Before lifting, a traction rope can be fixed behind the wall panel body 2, and other personnel manually assist in tightening the lower part of the wall panel body 2 to prevent the mobile vehicle from moving 3 too fast and the wall panel body 2 from tipping left or right. The upper back corner of the wall panel body 2 is protected by a multi-layer board or a plastic soft corner guard to prevent the top of the panel from wearing against the wire rope.

[0042] After pulling the guide chain 4 to make the wall panel body 2 reach the required height, pull the guide chain 4 in the opposite direction to gradually lower the wall panel body 2, and use the rope tightener to adjust the left and right and depth positions of the wall panel body 2 so that the upper ear slots are placed in the hook seats installed on the load-bearing base. At this time, the wall panel body 2 is in a suspended state, and the left and right positions and elevations of the wall panel body 2 are adjusted again to make them in the correct position. After the position is correct, install the wall panel body 2 in the correct position.

[0043] When the wall panel body 2 is installed, the steel support 5 and the guide chain 4 can be removed and moved to the next panel installation location. Other panels can be installed in the same way.

[0044] Furthermore, the guide chain 4 can slide on the long rod 12 following the sliding sleeve 13. According to the installation position, the personnel can change the position of the sliding sleeve 13. It should be noted that a third screw is provided on the outside of the sliding sleeve 13. When the position of the sliding sleeve 13 is determined, the sliding sleeve 13 can be fixed by the third screw.

[0045] The other two reinforcing mechanisms can enhance the supporting strength of the steel load-bearing bracket 5 between the structural beam and the top plate structural beam. At the same time, the anti-dumping column 8 can be extended and retracted according to the height between the different structural beams and the top plate structural beams to adjust the length between the anti-dumping column 8 and the telescopic rod 9, so as to adapt to different installation needs. Similarly, the rectangular sleeves 16 on the outside of the two vertical rods 14 can also be adjusted according to the needs. The height at which it is located on the vertical rod 14.

[0046] The two vertical rods 14 and the connecting rod 18 are in a U-shaped structure, and the two vertical rods 14 are respectively attached to the two sides of the structural beam.

[0047] Second screws 17 are disposed on the outer sides of the two rectangular sleeves 16 . The two second screws 17 are respectively pressed against the outer sides of the corresponding vertical rods 14 . The second screws 17 are used to press and fix the positions of the rectangular sleeves 16 .

[0048] A telescopic slot is provided at the bottom end of the anti-dumping column 8, and the telescopic rod 9 is slidably arranged inside the telescopic slot. A first screw 11 is provided on the outside of the anti-dumping column 8, and the first screw 11 is pressed tightly against the outside of the telescopic rod 9. The first screw 11 facilitates fixing the position of the telescopic rod 9 after it retracts and extends out of the telescopic slot.

[0049] The long rods 12 are distributed in parallel along the length direction of the structural beams and the top plate structural beams.

[0050] The heights of the two steel load-bearing brackets 5 are consistent, the square timber 6 and the corresponding cross bar 15 are distributed at a vertical angle, and the square timber 6 is arranged in the middle of the cross bar 15. The top end of the square timber 6 will contact the bottom end of the top plate structural beam, which can prevent the cross bar 15 and the long rod 12 from directly contacting the top plate structural beam surface, and act as a protective pad.

[0051] Example 2

[0052] An electric slide rail is fixed to the bottom end of the long rod 12 along the length direction, a slider is slidably matched on the electric slide rail, and the guide chain 4 is installed at the bottom end of the slider.

[0053] In this embodiment, by installing an electric slide rail, personnel can remotely control the movement of the slider, thereby driving the guide chain 4 to move, making it easy to adjust the position of the guide chain 4 and position and hoist the wall panel body 2 at different positions. This is more labor-saving and simpler than manually adjusting the position of the slide sleeve 13.
