Description

Technical Field

[0001] The utility model relates to the technical field of ALC wallboard hoisting in building construction, in particular to a special hoisting device for an adjustable ALC lightweight partition wall board. Background Art

[0002] ALC lightweight partition boards are widely used in the current construction industry. ALC lightweight partition boards are generally bundled with 3-4 panels. Due to the effects of friction and adhesion, bundles of ALC lightweight partition boards stick together. When installing ALC lightweight partition boards, the conventional method is to use a crowbar to forcefully wedge into the gaps of the ALC lightweight partition boards to separate them for use. After prying and shifting, a wire rope is inserted into the gap for hoisting and placed on a transport vehicle. In this process, the strong wedging of the crowbar and the prying process cause the edges of the ALC lightweight partition boards to be damaged and scratched, and the work efficiency is low. The wire rope hoisting process will also cause damage to the ALC lightweight partition boards, and there is also a safety hazard of hand crushing. After the installation of the ALC lightweight partition boards, the damaged edges need to be repaired, which is difficult to repair, increases the construction cost, and seriously affects the appearance quality and internal quality. Summary of the invention

[0003] In order to solve the technical problem of separating and hoisting bundled ALC lightweight partition boards, the utility model provides an adjustable special hoisting device for ALC lightweight partition boards, which clamps the uppermost wallboard of the bundled ALC lightweight partition boards through a hoisting fixture of a clamping structure, and the anti-slip plate of the concave-convex relative structure under the hoisting fixture is embedded and matched into the convex-concave surface of the side of the uppermost wallboard. The lifting force and horizontal thrust of the uppermost wallboard are clamped by the hoisting fixture, and the gravity of other wallboards below and the limiting thrust of a limiting rod on one side are cooperated to separate and hoist the ALC lightweight partition boards to a transport vehicle without damage, thereby effectively improving the problem of damage to the ALC lightweight partition boards during the unbundling process, ensuring the integrity of the ALC lightweight partition boards, improving the appearance quality and internal quality of the ALC lightweight partition boards after installation, and being safe and convenient to use.

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0018] like Figure 1-Figure 3As shown, the working principle of an adjustable special lifting device for ALC lightweight partition boards is as follows: the uppermost wall panel 16 of the ALC lightweight partition boards stacked in bundles on the placement plate 17 is lifted by a lifting fixture 1 with adjustable width, and the anti-slip plate with a concave-convex relative structure is embedded into the convex and concave surface on the side of the width direction of the uppermost wall panel 16. The lifting fixture 1 is lifted by the hook 13 of the single-arm crane 12. While the uppermost wall panel 16 is tightened, a lifting force N and a horizontal thrust F1 are given to the uppermost wall panel. Under the action of gravity G and the limiting force F2 of the side limiting rod, the uppermost wall panel 16 is separated from the wall panels 16 below it, and the uppermost wall panel 16 is lifted until the construction is completed.

[0019] like Figure 1-Figure 3 As shown, an adjustable ALC lightweight partition board special lifting device comprises a lifting ring 4, a steel wire rope 3 and a lifting fixture 1, wherein the lifting ring 4 is connected to the lifting fixture 1 through the steel wire rope 3, and the lifting fixture 1 is formed into a clamping structure through two clamping arms 2 of a crank structure, a row of adjustment holes 10 are arranged on the crank arm 2, and the two clamping arms 2 are connected by a pin shaft 9 arranged in the adjustment hole 10, and the row of adjustment holes 10 arranged on the crank arms of the two clamping arms 2 are matched and combined with each other, so that the two clamping arms 2 can be formed into a clamping structure lifting fixture 1 with different clamping widths to adapt to wall panels 16 of different widths, and the adjustment hole 10 can also form the lifting fixture 1 into a symmetrical clamping structure and an asymmetrical clamping structure to adapt to eccentric walls 16, A lifting ear 5 is provided at the upper end of the two clamping arms 2, and the lifting ear 5 is used to connect the wire rope 3. The lifting ring 4 on the wire rope 3 is lifted and tightened by the single-arm crane 12. The wire rope 3 tightens the clamping arms 2 on both sides to form a clamping force to clamp the wall panel 16. A protective plate 6 is provided on the inner side of the lower turning arm of the two clamping arms 2, and an anti-skid plate is provided on the inner side of the protective plate 6. The two anti-skid plates on the inner sides of the two clamping arms 2 are in a concave-convex relative structure. One of the two anti-skid plates is a concave anti-skid plate 7, and the other is a convex anti-skid plate 8. The two anti-skid plates are arranged in a concave-convex relative manner. The side surfaces on both sides of the wall panel 16 are concave-convex surface structures that can cooperate with the concave anti-skid plate 7 and the convex anti-skid plate 8, which can just cooperate and be embedded in the concave anti-skid plate 7 and the convex anti-skid plate 8 of the same concave-convex relative structure.

[0020] like Figure 1-Figure 2 As shown, further, the adjustable ALC lightweight partition board dedicated lifting device also includes a limit rod 14, the limit rod 14 is a telescopic structure, and a limit head 15 is arranged on the top of the limit rod 14.

[0021] Furthermore, the limiting head 15 is made of an elastic and soft material, which can avoid damaging the edge of the wall panel when limiting the movement of the lower wall panel.

[0022] like Figure 1-Figure 2 As shown, further, a handle 11 is provided on the outer side of the lower crank arm of the clamping arm 2.

[0023] Furthermore, the anti-skid plate is a rubber plate with anti-skid patterns. The rubber plate is elastic. The elastic material prevents damage to the edges of the uppermost wall panel 16 during separation and hoisting. The anti-skid patterns provide friction to prevent the uppermost wall panel 16 from slipping during separation and hoisting.
