[0038] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. Please note that the following embodiments are only illustrative of the present invention and are in no way intended to limit the scope of the present invention.
[0039] The present invention makes full use of high-performance new flexible plastic materials, such as EPP, graphene EPS or EPE materials, to make hoisting transportation protection components. It is specifically aimed at 3D printed buildings, structures, and building components and other large transportation parts. Of course, it is also suitable for Other hoisting and transportation occasions.
[0040] The hoisting and transportation protection assembly of the present invention includes a pallet that can be used alone or in combination, and protection pieces of various shapes. According to the volume and weight of the transport parts to be hoisted and transported, pallets and protective parts of different shapes and sizes can be selected. The protective member includes a protective strip 5, a peripheral protective belt 6, a three-dimensional protective corner 7 and an umbrella protective cap. Among them, during transportation, the pallet supports the transport parts to be transported from below, and the protective parts of various shapes protect the transport parts to be transported from different positions. The lifting straps are used to wrap the support pallets and the protective parts, and the use of such as adhesive tape is suitable. Adhesive adhesive tape, and then the transport parts for safe transportation.
[0041] Such as Figure 1A to Figure 1D Shown are the front view, side view, top view and bottom view of the tray in the hoisting transportation protection assembly of the present invention. Wherein, the pallet is a rectangular triple-leg support pallet, that is, a three-legged pallet, but the shape of the pallet of the present invention is not limited to this, and it can be changed according to the shape of the transport.
[0042] The pallet includes a pallet body 1, and a plurality of pallet feet 3 are arranged at intervals below the pallet body 1. In this embodiment, the number of pallet feet is 3, but the present invention is not limited to this, and it may be 2 or more. The tray foot 3 is located in the middle of the tray body 1 in the short-side direction. The bottom of the tray foot 3 is provided with a heating and cooling hole 8; the heating and cooling hole 8 is used to quickly heat and cool the tray during molding, which not only improves the single product production Efficiency, doubled the production cost and increased the single machine capacity, and also prevents the tray foot 3 from being excessively expanded in the mold due to high temperature during mold release, which is difficult to demold, prevents scrapping, improves the product yield, and can also absorb shock during use Fight, reduce the overall weight of the pallet, reduce the consumption of high-performance EPP materials, and reduce the total cost.
[0043] The two sides of the pallet body 1 in the short-side direction are used as transportation forklifts or hoisting working surfaces. In addition, a side plate 2 extending upward is arranged in the middle of the side of the tray main body 1. The side plate 2 is provided with a groove 4, and an RFID electronic tag can be embedded in the groove 4, and a plexiglass protective plate with an anti-aliasing two-dimensional code can be arranged on the outside of the groove 4 to facilitate customers to scan the code uniformly.
[0044] Such as Figure 2A with Figure 2B As shown, they are respectively a front view and a side view of the protective strip 5 in the hoisting transportation protective assembly of the present invention. The protective strip 5 is in the shape of a bendable belt and is provided with a hoisting belt card slot on one side (the side opposite to the side in contact with the transport part to be transported) (see Figure 2B ). During transportation, the protective strip 5 is tightly combined with the surface of the transport piece to be transported to protect the surface of the transport piece, which is suitable for the protection of flat, curved, and spherical products.
[0045] Such as Figure 3A with Figure 3B As shown, they are respectively a front view and a side view of the peripheral protective belt 6 in the hoisting transportation protective assembly of the present invention. The peripheral protective belt 6 is L-shaped and a lifting belt card slot is arranged on the outer side of the L-shaped (see Figure 3B ). During transportation, the peripheral protective belt 6 is tightly combined with the junction of the two surfaces of the transport item to be transported, thereby protecting the sides of the transport item.
[0046] Such as Figure 4A with Figure 4B Shown are the front schematic view and the back schematic view of the three-dimensional protective corner 7 in the hoisting transportation protection assembly of the present invention. The three-dimensional protection angle 7 is a three-dimensional wrap angle formed by three mutually perpendicular surfaces. During transportation, the three-dimensional wrap-around inner surface of the three-dimensional protective corner 7 is tightly combined with the corner of the transport piece to be transported, and is bonded to the corner of the transport piece to be transported by an adhesive tape, etc. The corners of the pieces are protected.
[0047] Such as Figure 5A with Figure 5B Shown are a schematic top view and a schematic side view of the umbrella-shaped protective cap in the hoisting transportation protection assembly of the present invention. The umbrella-shaped protective cap is arcuate. When transporting transport parts with curved surfaces (such as spherical 3D printed buildings, structures and building components, etc.), the arc surface of the umbrella-shaped protective cap is closely integrated with the arc surface of the transport part to be transported. It is bonded to the curved surface of the transport part to be transported by an adhesive tape or the like to protect the curved surface of the transport part to be transported.
[0048] Such as Image 6 As shown, it is a schematic diagram of the state of the hoisting transportation protection assembly of the present invention when used in combination. Among them, taking non-spherical 3D printing large transport parts such as buildings, structures and building components as examples, the hoisting transport protection assembly of the present invention is used: first, according to the overall size and weight of the transport parts, select the corresponding support tray and protection In this example, it is determined that a three-dimensional protective corner 7 will be installed on each corner of the transport piece, a peripheral protective belt 6 will be installed on each periphery, and a protective strip 5 will be installed on each surface. Second, install the selected support tray and guards in place. For example, the three-dimensional protective corners 7 are glued to the corners of the transport piece, the peripheral protective tape 6 is arranged on each side of the transport piece, and the protective strip 5 is arranged on each surface of the transport piece. Then, put the hoisting belt into the hoisting belt slot in the protective part, and wind the transportation parts to ensure that the hoisting belt does not leave the slot during hoisting operation, thereby protecting the 3D printed buildings, structures and building component products from damage.
[0049] In addition, for large transportation parts such as 3D printed buildings, structures and building components with spherical surfaces, the hoisting transportation protection assembly of the present invention is similar to the above process when used, and the difference is that the curved surface of the transportation parts is appropriately The umbrella-shaped protective cap is bonded and the protective strip 5 is arranged, and it is transported with the lifting belt.
[0050] It can be seen from the above that the present invention can not be restricted by the shape of 3D printed buildings, structures and building components, but according to the volume and weight of the transport parts to be transported, different sizes of hoisting transportation protection components can be selected, and hoisting and transportation can be carried out with the hoisting belt. Transportation safety protection operations are suitable for 3D printing buildings, structures and building components with various complex shapes.
[0051] Hereinafter, the production method of the hoisting transportation protection assembly of the present invention is introduced.
[0052] Such as Figure 7 Shown is a flow chart of the production method of the hoisting transportation protection assembly of the present invention. The production method of the hoisting transportation protection assembly of the present invention is as follows.
[0053] First, design the structure and size of the hoisting transportation protection component according to the volume, weight and shape of the transport parts to be transported, such as designing the detailed dimensions of the pallet and each protection component to minimize the structure and size of the hoisting transportation protection component to save materials Dosage and reduce costs.
[0054] Second, determine the raw materials to be used and the corresponding parameters according to the structure and size of the hoisting and transportation protection components. In this step, the raw materials used in the present invention are EPP, graphene EPS or EPE materials. When EPP is used, the parameter is the expansion ratio of EPP; when graphene EPS is used, the parameter is the bulk density of graphene EPS; when EPE is used, the parameter is the bulk density of EPE. Among them, the method of determining the raw materials to be used and the corresponding parameters can be referred to Figure 8.
[0055] Figure 8 It is a comparison table for determining the expansion ratio or bulk density of the present invention. According to the specific structure and size of the hoisting transportation protection component, select the corresponding foaming ratio or bulk density from the table. For example, when the tray is light (<2(T)) and the length, width, and height are 1200×580×240 (mm), the expansion ratio is 20 when EPP is selected, and the bulk density is 20 when graphene EPS is selected. Similarly, when the umbrella-shaped protective cap is medium (2~5(T)), the bottom diameter is 300~500(mm), and the cone height is 30~120(mm), the foaming magnification is 20 when EPP is selected. The bulk density for EPS is 20. Similarly, when the protective strip 5 is heavy (>5(T)) and its length, width and height are (1200-2400)×500×(50-100) (mm), the bulk density of EPE is 25-30.
[0056] Third, let the raw materials enter the immersion tank for pressure foaming or directly into the foaming machine for precise foaming to obtain suitable foaming materials.
[0057] Fourth, the raw material after foaming enters the molding machine for molding to obtain a molded protective component. Or make the raw material after foaming directly enter the extruder for extrusion molding, and the finished product is directly after extrusion molding. When EPP and EPS are formed, special aluminum alloy molds can be used for one-time forming in the same set of molds according to the appropriate number of pieces. EPE products use special steel molds to form products. For example, the three-dimensional protection angle 7 and the peripheral protection belt 6 have a number ratio of 1:3.
[0058] Fifth, the molded protective component obtained by molding by the molding machine is shaped and dried, and the component extruded by the extruder does not need to go through this step, thereby obtaining the finished product of the lifting and transporting protective component.
[0059] Finally, the hoisting transportation protection components can be inspected and put into storage, and then sold and delivered to the factory.
[0060] It can be seen from the above content that the production method of the hoisting transportation protection component of the present invention adopts one-time molding or extrusion molding, and the structure and anti-collision bearing capacity of the hoisting transportation protection component can be standardized and optimized according to actual needs.
[0061] The hoisting transportation protection component of the present invention adopts EPP, graphene EPS and EPE materials, so it has superior compression resistance, anti-collision and impact resistance, and has thermal insulation, anti-vibration and anti-skid; at the same time, it is not easy to be damaged during use and can be completely recycled Recycling is not only environmentally friendly, but also greatly reduces the user's cost of use.
[0062] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The broadest interpretation of the scope of the appended claims should be given so as to cover all these modifications and equivalent structures and functions.
