In other embodiments, the lower clamp 32 can be attached to the bottom of the fixing rod 31 , and the lower clamp 32 and the fixing rod 31 are connected and fixed through the second limiting member 83 . That is to say, at this time, a second limiting hole extending vertically is opened on the fixing rod 31, and a waist hole extending transversely is opened on the bottom plate 321, and the second limiting member 83 passes through the second limiting hole and the waist at the same time. hole.

In this implementation, a second anti-slip pad is attached to the inner wall of each limiting groove to increase the friction between the inner wall of each limiting groove and the wallboard, and prevent the wallboard from sliding in the limiting groove.

The hoisting tool hoisting wall panel steps are as follows:

First, according to the thickness of the wallboard, the lateral distance between the two clamping plates 2211 is adjusted by sliding the bent plate 221 away from the telescopic rod 212, and the lateral distance between the side plate 322 and the fixed rod 31 is adjusted by sliding the lower clamp 32 . Moreover, according to the longitudinal dimension of the wallboard when it is placed on the hoisting tool, the longitudinal distance between the connecting plates 2212 in the two upper clamps 22 is adjusted by respectively sliding the two telescopic rods 212 relative to the rotating arm 211 . For the convenience of putting the wallboard into the hoisting tool, the longitudinal distance between the longitudinal inner ends of the splint 2211 in the two upper clamps 22 can be greater than the longitudinal dimension of the wallboard, as the initial dimension along the longitudinal direction between the two upper clamps 22.

Then put the wallboard into the clamping groove and the limiting groove. Taking a wallboard with a rectangular cross-section as an example, the length direction of the wallboard can be placed vertically, or the width direction of the wallboard can be placed vertically.

Slide the bending plate 221 away from the telescopic rod 212 again so that the two clamping plates 2211 of the upper clamp 22 are respectively attached to the two ends of the wallboard along the transverse direction, and at the same time slide the lower clamp 32 so that the side plates 322 are attached to the lateral outer end surfaces of the wallboard, and The lower clamp 32 is limited by the limiting member 8 .

Then, the lifting lug 4 is assembled with the sling of the lifting device, and the rotating arm 211 is driven to rotate upwards through the cooperation of the sling and the lifting lug 4. At this time, the reset part 7 is stretched and becomes longer, and the sliding part 6 drives each upper clamp 22 to rotate upwards. Rotate the telescopic rod 212, so that the snap-in groove remains vertically penetrated, and the longitudinal dimension between the two upper clamps 22 is reduced due to the inclination of the telescopic member 21, so that the upper clamp 22 is close to and close to the longitudinal end of the wallboard portion, and then the two upper clamps 22 can automatically clamp the wallboard without manual assistance.

Continue to lift the sling, and the hoisting tooling is lifted together with the wallboard. After reaching the designated installation position and the wallboard is installed and fixed, the sling is lowered, and the reset part 7 provides a reaction force to the rotating arm 211 due to automatic contraction, driving The rotating arm 211 rotates downwards and returns to the state of longitudinal extension. At this time, the longitudinal dimension between the two upper clamps 22 is greater than the longitudinal dimension of the wallboard, and the wallboard can be automatically released without manual assistance. Then the sling continues to descend, driving the hoisting tooling back to the ground.

When the wallboard is placed in the hoisting tool, the bottom plate 321 is positioned at the bottom of the wallboard to support the wallboard. The support bar 1, the limiting groove and the clamping groove cooperate together to realize the lateral limit of the wallboard. At the same time, the two clamping grooves can also The longitudinal limit of the wall panel is realized, so that the wall panel will not shake left and right during hoisting, and will not slip halfway, and can be smoothly hoisted to the designated installation point, which improves the safety and reliability of the wall panel hoisting.

When the hoisting tool is used to hoist the same batch of wall panels, the dimensions and specifications of the same batch of wall panels are basically the same, so the hoisting tool does not need to adjust the upper fixture when hoisting the remaining wall panels after hoisting one wall panel 22 and the transverse dimension of the lower fixture 32, without adjusting the longitudinal distance between the two upper fixtures 22, the wallboard can be directly placed in the limit groove, which saves time and improves the efficiency of wallboard hoisting. When hoisting the next batch of wallboards of different sizes, it is only necessary to adjust the transverse dimensions of the upper clamp 22 and the lower clamp 32 and the longitudinal distance between the two upper clamps 22 when the hoisting starts.

As can be seen from the above technical solutions, the utility model has at least the following advantages and positive effects:

First, the hoisting tooling in this application clamps and limits the wallboard through the clamping groove and the limiting groove, and the two upper clamps can move to approach or move away from each other to adjust the longitudinal dimension between the two upper clamps. The utility model can adapt to wallboards of different sizes to hoist the wallboards of different sizes, which enhances the versatility of the hoisting tool.

Second, in the present application, the lateral dimensions of the upper clamp and the lower clamp can be adjusted, and can adapt to wallboards of different thicknesses to hoist wallboards of different sizes, thereby enhancing the versatility of the hoisting tool.

Third, the hoisting tooling in the present application cooperates with the sling of the hoisting equipment to drive the telescopic element to rotate upwards or downwards. Returning to the state of longitudinal extension and returning to the initial state can realize the automatic clamping of the two upper fixtures or the automatic loosening of the wall panels without manual assistance, which not only greatly improves the hoisting efficiency and construction safety, but also effectively reduces the labor of workers. strength.
