Detailed implementation manners

[0028] The following further describes this application in conjunction with specific embodiments and the attached drawings.

[0029] Refer to Figure 1 As shown, a tool for hoisting a laminated board includes a first connecting section 1, a first hoisting section 2, a second connecting section 3, a second hoisting section 4, an expansion joint 5, an expansion adjustment structure and a hoisting function structure.

[0030] The first connecting section 1 and the second connecting section 3 are two 20# I-beams, the first hoisting section 2 and the second hoisting section 4 are four channel steels with a thickness of 10 mm, a length of 700 mm and a width of 200 mm, and the expansion joint 5 is two channel steels with a thickness of 10 mm, a length of 1200 mm and a width of 185 mm.

[0031] The first hoisting section 2 is welded at both ends of the first connecting section 1, and an I-shaped structure is formed between the first connecting section 1 and the first hoisting section 2. The second hoisting section 4 is welded at both ends of the second connecting section 3, and an I-shaped structure is formed between the second connecting section 3 and the second hoisting section 4. The connecting section and the hoisting section together form a rectangular frame structure, thus ensuring the structural stability of the whole tool.

[0032] An expansion joint 5 is provided between the first hoisting section 2 and the second hoisting section 4, and an expansion adjustment structure is provided between the first hoisting section 2 and the expansion joint 5 and between the second hoisting section 4 and the expansion joint 5. By changing the relative length between the hoisting section and the expansion joint through the expansion adjustment structure, the span of the whole tool can be changed to meet the hoisting of laminated boards with different specifications and sizes.

[0033] Refer to Figure 2 As shown, the notches of the first hoisting section 2 and the second hoisting section 4 are arranged opposite to the notch of the expansion joint 5. By arranging the notches of the channel steels opposite to each other, the reliability of the connection between the two channel steels is ensured, and the relative swing between the two channel steels can be avoided. In addition, by ensuring that the notch height of the hoisting section is the same as the height of the expansion joint, the vertical fixation and clamping between the two channel steels are also achieved.

[0034] Refer to Figure 1, Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 , the telescopic adjustment structure between the first lifting section 2 and the telescopic section 5 includes a number of first adjustment holes 6 on the first lifting section 2 and a number of telescopic adjustment holes 8 on the telescopic section 5. An adjustment bolt 9 is passed through between the first adjustment hole 6 and the telescopic adjustment hole 8 for connection.

[0035] The telescopic adjustment structure between the second lifting section 4 and the telescopic section 5 includes a number of second adjustment holes 7 on the second lifting section 4 and a number of telescopic adjustment holes 8 on the telescopic section 5. An adjustment bolt 9 is passed through between the second adjustment hole 7 and the telescopic adjustment hole 8 for connection.

[0036] For the first lifting section 2 and the second lifting section 4, that is, there is a hole every 100 mm on the channel steel, the hole diameter is 20 mm, and there are 6 holes on each channel steel. The telescopic section has a total of 12 holes that match the aperture and position of the channel steel. When the adjustment bolt 9 is passed through the corresponding telescopic adjustment holes and the first and second adjustment holes, the relative fixation between the lifting section and the telescopic section can be realized. By changing the adjustment holes into which the adjustment bolt is inserted at different positions, the adjustment of the telescopic amount can be carried out.

[0037] Reference Figure 4 As shown in Figure 4 , lifting structures are welded to the upper and lower parts of the first lifting section 2 and the second lifting section 4, and the lifting structures are lifting lugs 10. The lifting lug 10 includes an ear plate and a base plate. The base plate is welded and fixed on the first lifting section 2 and the second lifting section 4, the ear plate is welded and fixed on the base plate, and the ear plate has an ear hole.

[0038] The four-corner lifting lugs of the channel steel are finished lifting lugs, which are fully welded to the four ends of the channel steel. The size of the base plate is 80 mm wide and 30 mm thick, the ear plate hole is 30 mm and the length is 160 mm, and a rubber protective sleeve is used to protect the connection between the ear plate and the steel wire rope.

[0039] The working process of this application: Reference Figure 5 As shown in Figure 5 , the lifting rope 11, that is, the steel wire rope for lifting, uses 4 pieces of 6×37 - 1570 - 24 mm steel wire ropes. The lower end uses a turnbuckle to connect with the truss of the laminated board 12, and the upper end also uses a turnbuckle to connect with the lower lifting lug of this tool. The upper hook uses four steel wire ropes to connect with the upper lifting lug of this tool.
