Technical Field

[0001] The utility model belongs to the field of prefabricated component construction of assembled buildings, and is mainly used for on-site lifting and storage of composite panels. It can quickly realize the lifting, installation and precise positioning of composite panels. The device is easy to manufacture, has strong practicality and promotion, and can generate obvious economic and social benefits. Background Art

[0002] At present, in the field of prefabricated component hoisting for assembled buildings, prefabricated composite board components are heavy and large in size. The safety of the lifting points is difficult to control during the hoisting process, resulting in common quality problems such as center of gravity deviation and bending deformation that affect the installation and affect the subsequent use and forming effect of the composite board. Summary of the Invention

[0003] In order to avoid common quality problems affecting installation such as center of gravity deviation and bending deformation of the composite plate during lifting, the utility model provides an assembled two-way adjustable composite plate lifting device.

[0004] An assembled bidirectionally adjustable composite plate lifting device is characterized in that it consists of a fixed bracket, an adjustable connecting rod, a claw arm, and bolts; the fixed bracket and the adjustable connecting rod are fixedly connected by bolts, and the claw arm is fixed to both ends of the fixed bracket by bolts.

[0005] The fixing bracket is composed of a longitudinal square tube and a horizontal square tube welded at 90 degrees; connection holes for fixing the claw arm rod are evenly spaced at both ends of the longitudinal square tube; one end of the horizontal square tube is welded to the longitudinal square tube, and connection holes for fixing the adjustable connecting rod are evenly spaced at the other end of the horizontal square tube.

[0006] The adjustable connecting rod is a short square tube, and connecting holes are arranged at equal intervals on both side walls of the short square tube. The connecting holes are connected and fixed to the connecting holes on the horizontal square tube on the fixed bracket by bolts.

[0007] The claw arm is a thin square tube thinner than the horizontal square tube. Connection holes are set at equal intervals at one end of the claw arm. The end with the connection holes is inserted into the longitudinal square tube of the fixed bracket and connected by bolts. A lifting hole is set at the other end of the claw arm.

[0008] The utility model can be adjusted according to the length and width dimensions of the composite plate to meet the lifting requirements. The long side dimension can be adjusted by adjusting the length of the claw arm 3 through the longitudinal bolt group 4, and the short side dimension can be adjusted by the distance between the horizontal bolt group 5 and the two ends of the adjustable connecting rod 2.

[0009] During implementation, the dimensions of the present invention are determined in advance based on the dimensions of the stacked panels. Before installation, the longitudinal square tubes of the present invention's long sides can be adjusted proportionally to the length of the claw arm 3 using the longitudinal bolt assembly 4. The short square tubes of the short sides can be adjusted proportionally to the distance between the ends of the adjustable connecting rod 2 using the horizontal bolt assembly 5, ensuring that the centroid distance of the present invention coincides with the centroid distance of the stacked panels being installed.

[0010] After the dimensions of the utility model are determined, first connect the hook sling to the lifting holes of the claw arm at the four corners of the utility model for trial lifting and leveling, then connect the four corners of the composite board to the four lifting holes of the utility model through the sling. When the composite board and the utility model are kept in a horizontal and parallel state during the trial lifting, lift it to prevent the center of gravity of the composite board from deviating and bending deformation during the lifting process. (If Figure 5 shown)

[0011] The utility model has a simple structure, can be recycled, reduces material costs, and has strong practicability and popularization. BRIEF DESCRIPTION OF THE DRAWINGS
