Abstract
Description
Technical Field
[0001] The invention relates to the technical field of packaging boxes and hoisting, and in particular to a hoisting assembly based on a shackle composite rotating hoisting ring and a hoisting method thereof. Background Art
[0002] Large packaging boxes are heavy in weight, and even heavier when loaded with products. Therefore, a crane is needed to lift them during turnover and transportation. Generally speaking, packaging box manufacturers will design lifting devices on both sides of the box body 4. The most common lifting device on the market is a rotating lifting ring 1, which has a structure as shown in the figure. Figure 1 As shown, the left side is a side view of the rotating lifting ring 1, and the right side is a front view of the rotating lifting ring 1. The rotating lifting ring 1 mainly includes a U-shaped lifting ring body 1-1, a pin 1-2, and a bolt 1-3, wherein the pin 1-2 is fixed at both ends of the U-shaped lifting ring body 1-1 and can rotate freely, one end of the bolt 1-3 is fixedly connected to the pin 1-2, and the other end is fixed to a fixed point on the side of the box body 4. Considering factors such as hoisting safety, the rotating lifting ring 1 cannot be directly connected to the soft sling 3 during actual operation, and needs to be used together with a shackle 2 (the structure is similar to that of the rotating lifting ring 1). The soft sling 3 and the rotating lifting ring 1 are transferred through the shackle 2 to lift the packaging box.
[0003] Analysis shows that there are some problems with the existing packaging box lifting method: ① When lifting, it is necessary to prepare a soft sling 3 and a shackle 2 and connect the two with the rotating lifting ring 1, which is not only inconvenient to operate but also easy to lose the shackle 2; ② Figure 2-3 As shown, the shackle 2 and the rotating lifting ring 1 are in a 90° cross state when they are connected. When the packaging box is lifted, the metal shackle 2 will inevitably squeeze the box body 4 ( Figure 2 The packaging box and its contents are damaged. Summary of the invention
[0004] One of the purposes of the present invention is to solve the above-mentioned problems existing in the prior art, and to provide a new type of lifting assembly, which includes a shackle composite rotating lifting ring 5 and a soft lifting belt 3. The shackle composite rotating lifting ring 5 includes an H-shaped lifting ring body 5-1, a connecting bolt 5-2, a connecting pin 5-3, and a shackle pin 5-4. The connecting pin 5-3 is fixed on the two vertical arms at the lower end of the H-shaped lifting ring body 5-1, and the H-shaped lifting ring body 5-1 can rotate freely around the connecting pin 5-3. The shackle pin 5-4 is fixed to the two vertical arms at the upper end of the H-type lifting ring body 5-1, and the H-type lifting ring body 5-1 can rotate freely around the shackle pin 5-4; one end of the connecting bolt 5-2 is fixed to the box body 4 of the large packaging box, and the other end is fixedly connected to the connecting pin 5-3, and the H-type lifting ring body 5-1 can rotate freely around the connecting bolt 5-2; the soft sling 3 is connected to the crane after passing through the hole between the shackle pin 5-4 and the H-type lifting ring body 5-1.
[0005] Furthermore, the H-shaped lifting ring body 5-1 is formed by integral metal casting to ensure its structural strength.
[0006] Furthermore, structural reinforcement ribs are provided at the intersections of the horizontal arm in the middle of the H-shaped lifting ring body 5-1 and the vertical arms on the left and right sides.
[0007] Furthermore, the distance between the cross arm in the middle of the H-shaped lifting ring body 5-1 and the connecting pin 5-3 is smaller than the distance between the cross arm and the shackle pin 5-4. The cross arm of the H-shaped lifting ring body is located lower, which is convenient for placing the soft lifting belt.
[0008] Furthermore, the connecting pin 5-3 and the shackle pin 5-4 are installed in parallel on the H-shaped lifting ring body 5-1, and are perpendicular to the two vertical arms of the H-shaped lifting ring body 5-1.
[0009] Furthermore, the number of the shackle composite rotating lifting rings 5 is an even number (such as 2, 4, 6, 8), and they are symmetrically distributed on both sides of the box body 4 of the large packaging box.
[0010] Furthermore, the lifting assembly also includes a lifting plate 6 and a lifting rope 7. The two ends of the soft lifting belt 3 are fixedly connected to the shackle composite rotating lifting ring 5 and the lifting plate 6 respectively, and the lifting plate 6 is connected to the crane through the lifting rope 7.
[0011] The second object of the present invention is to provide a method for lifting a large packaging box using the above-mentioned lifting assembly, comprising: first, symmetrically fixing the shackle composite rotating lifting ring 5 on the side of the large packaging box, then fixing the two ends of the soft sling 3 to the shackle composite rotating lifting ring 5 and the crane, and then lifting.
[0012] The lifting assembly provided by the present invention avoids the problems of easy loss and damage to the side wall of the packaging box caused by squeezing when using the shackle in the past. Through the shackle composite rotating lifting ring that can rotate freely and in multiple directions, it is ensured that the axis of the shackle pin shaft is basically parallel to the side of the box body when using it to transfer the soft lifting belt, so that the appearance of the packaging box is intact during the lifting process.
[0013] Compared with existing similar products, the improvements of the present invention are mainly reflected in the following aspects: (1) It abandons the traditional combination of rotating lifting ring + shackle, and integrates the functions of the original two different parts into one part through innovative structural design, thereby reducing the number of parts and improving connection efficiency; (2) The shackle composite rotating lifting ring has a simple structure and is easy to use, and will not cause damage to the packaging box body, and is more acceptable to customers; (3) It solves the practical problems that have plagued us for a long time with a lower cost and a relatively simple solution, achieving cost reduction and efficiency improvement.

DETAILED DESCRIPTION
[0023] In order to enable ordinary technicians in the field to fully understand the technical solutions and beneficial effects of the present invention, the following is a further detailed description in conjunction with specific embodiments and drawings.
[0024] like Figure 4-8 A large packaging box lifting assembly shown in the figure mainly includes a shackle composite rotating lifting ring 5, a soft sling 3, a lifting plate 6, and a sling 7, wherein a plurality of shackle composite rotating lifting rings 5 are symmetrically fixed on both sides of a box body 4 of the large packaging box, one end of the soft sling 3 is fixedly connected to the shackle composite rotating lifting ring 5, and the other end of the soft sling 3 is fixed on the lifting plate 6, and the lifting plate 6 is connected to the crane through the sling 7, thereby completing the lifting operation of the large packaging box.
[0025] Unlike the previous method of using a rotating eyelet 1 and a shackle 2 together, the new lifting assembly only needs one part, the shackle composite rotating eyelet 5, to complete the lifting, which is equivalent to integrating the functions of the previous two and has a simpler structure and is more convenient to use. Figure 4As shown (from left to right, the main view, the side view, and the main view of another state, respectively), the shackle composite rotating lifting ring 5 is made of high-strength metal integrally cast, including an H-shaped lifting ring body 5-1, a connecting bolt 5-2, a connecting pin 5-3, and a shackle pin 5-4. The shackle pin 5-4 and the connecting pin 5-3 are fixed in parallel on the H-shaped lifting ring body 5-1 at a certain distance above and below to form an "8"-shaped structure. The connecting bolt 5-2 is movably fixed in the through hole on the connecting pin 5-3 and is limited. The shackle composite rotating lifting ring 5 can be fixed to the box body 4 of the large packaging box through the connecting bolt 5-2. Due to the use of multiple sets of pins and rotating structures, the H-shaped lifting ring body 5-1 can rotate around the connecting bolt 5-2, the connecting pin 5-3, and the shackle pin 5-4 in different planes, thereby adapting to different lifting angles.
[0026] The lifting assembly provided by the present invention has the advantages of simple structure and easy use, and avoids the defect of squeezing the box body in the previous use of shackle adapters. It not only improves the convenience of lifting operation, but also has only one accessory that is not easy to lose and is easy to keep, and the comprehensive cost of lifting large packaging boxes is lower.
