Description

Technical Field

[0001] This utility model relates to lifting and securing devices, and in particular to a lifting and securing device for a large rotomolded packaging box. Background Technology

[0002] Generally, rotomolded packaging boxes are lifted using slings. This method is simple and easy to implement, and has no special requirements for the lifting interface of the packaging box, making it the preferred method for lifting most small and medium-sized rotomolded packaging boxes. However, when manufacturing large rotomolded packaging boxes, due to their own weight and the mass of their contents, relying on slings for lifting can easily cause falls, and the lifting stability is also poor. Therefore, it is necessary to redesign a special lifting device for auxiliary lifting. Summary of the Invention

[0003] The purpose of this utility model is:

[0004] To avoid the risk of falls caused by the heavy weight of the lifting device and the contents of large rotomolded boxes, which are easily lifted by slings, a lifting and reinforcement device for large rotomolded boxes is proposed, which can improve the stability and safety of lifting large rotomolded boxes.

[0005] The technical solution of this utility model:

[0006] A lifting and securing device for a large rotomolded packaging box consists of four parts: lifting ring 1, load-bearing side plate 2, transverse connecting rod 3, and lifting mechanism 4.

[0007] The load-bearing side plate 2 is divided into left and right sections, with a lifting base arranged on the upper part for installing the lifting ring 1; the transverse connecting rod 3 is divided into upper and lower sections, which connect the left and right side plates on the upper and lower sides respectively, so that the entire lifting and reinforcement device forms a closed overall frame; the lifting mechanism 4 consists of two parts: the lifting base plate 5 and the stop block 6. The lifting base plate 5 is used to support the large rotomolded packaging box 7. The lifting base plate 5 has a through hole in the middle, and the load-bearing side plate 2 passes through the through hole in the middle of the lifting base plate 5 and cooperates with the stop block 6 to fix the lifting base plate 5.

[0008] Its distinguishing feature is that the lifting ring is forged from alloy steel, and the lifting ring, together with the lifting device, completes the lifting of the packaging box.

[0009] Its characteristic feature is that the lifting ring 1 is hooked by the hook of the lifting device during lifting.

[0010] Its characteristic is that adjusting the placement position of the large rotomolded packaging box 7 on the lifting base plate 5 can adjust the lifting area of ​​the lifting base plate 5, significantly reducing the stress level of the large rotomolded packaging box 7 during lifting.

[0011] Its characteristic feature is that the load-bearing side plate 2 is made of aluminum alloy material and machined.

[0012] Its characteristic feature is that the transverse connecting rod 3 is machined from aluminum alloy material.

[0013] Its characteristic feature is that the lifting mechanism 4 is machined from aluminum alloy material.

[0014] The beneficial effects of this utility model are:

[0015] This utility model discloses a lifting and reinforcement device for large rotomolded packaging boxes, which can improve the stability and safety of lifting large rotomolded packaging boxes, and at the same time reinforce the box body to avoid local deformation caused by lifting.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] This utility model discloses a lifting and securing device for a large rotomolded packaging box, which consists of four parts: a lifting ring 1, a load-bearing side plate 2, a transverse connecting rod 3, and a lifting mechanism 4; for example... Figure 1 As shown. The load-bearing side plate 2 is divided into left and right sections, with a lifting base arranged on the upper part for installing the lifting ring 1; the transverse connecting rod 3 is divided into upper and lower sections, which connect the left and right side plates on the upper and lower sides respectively, so that the entire lifting and reinforcement device forms a closed whole frame.

[0020] like Figure 2 As shown, the lifting mechanism 4 consists of two parts: a lifting base plate 5 and a stop block 6. The lifting base plate 5 is used to support the large rotomolded packaging box 7. The lifting base plate 5 has a through hole in the middle. The load-bearing side plate 2 passes through the through hole in the middle of the lifting base plate 5 and cooperates with the stop block 6 to fix the lifting base plate 5.

[0021] The lifting ring 1 is forged from 30CrMnSiA alloy steel and can be used with lifting devices to lift the packaging box. The load-bearing side plate 2 is machined from aluminum alloy and is symmetrically arranged on both sides of the front and rear ends of the box body 7. It is used to install and fix the lifting ring 1 and also to reinforce the sides of the box body. The transverse connecting rod 3 is also machined from aluminum alloy and is used to connect the left and right load-bearing side plates 2 at the top and bottom ends, connecting the entire lifting and reinforcement device into a whole, which plays a role in reinforcement and stability. The lifting mechanism 4 is also machined from aluminum alloy and is used to lift the entire box body 7 from the bottom. By increasing the area of ​​the upper surface of the lifting base plate 5 of the lifting mechanism 4, the stress level when lifting the box body 7 is reduced, and excessive overload damage to the box body is prevented. The lifting base plate 5 is fixed to the load-bearing side plate 2 by the stop block 6.
