Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical equipment processing and manufacturing technology, and in particular to a packaging box for the turnover of parts in a mechanical manufacturing plant. Background Technology
[0002] In the field of mechanical equipment manufacturing, especially for heavy equipment such as boilers and pressure vessels, and special equipment, fasteners such as flanges, elbows, tees, and bolts, as well as small steel plates and small connecting pipes, are collectively referred to as manufacturing connectors in the process of assembling these components into the final product. They are characterized by their manufacturing and processing turnover attributes, as well as their small size, varied shapes, large total quantity, large total weight, and wide variety.
[0003] Currently, for the aforementioned manufacturing connectors, the workshop turnover process often utilizes the original packaging boxes provided by suppliers or lacks specific packaging. This type of packaging is generally based on low-cost, disposable wooden crates, providing only basic component protection and lacking the functionality for reusing manufacturing connectors. The crates have several drawbacks: low reusability during handling; low load capacity per crate; inability to reliably handle connectors multiple times using cranes, forklifts, or other equipment; and the lack of stacking capability, resulting in additional space occupation in the workshop. Furthermore, there are inherent safety risks associated with loose bundling and crating during handling, and parts are easily damaged due to the flimsy packaging. Inconvenience for on-site operators makes it difficult to inventory and store connectors, hindering manufacturing support work.
[0004] The turnover boxes currently used in the logistics and express delivery industry have poor load-bearing capacity and cannot be used for the turnover of mechanical parts. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model designs a packaging box for the turnover of parts in a machinery manufacturing plant. It mainly solves the problem of centralized handling and verification of manufacturing connecting components that are small in size, have different shapes, large in quantity, and heavy in weight during the machining process, so as to ensure safety and reliability throughout the manufacturing process.
[0006] The present invention adopts the following technical solution:
[0007] A packaging box for the turnover of parts in a machinery manufacturing plant includes a basic frame structure. The bottom of the inner side of the basic frame structure is detachably equipped with a bottom reinforcement structure. The sides of the basic frame structure are covered with a closed inner support structure. Bottom and top supports are respectively installed at the four corners of the bottom and top of the basic frame structure. The bottom and top supports are nested together. Lifting lugs are respectively fixedly installed on the upper sides of the front and rear sides of the basic frame structure.
[0008] Preferably, the basic structure of the frame includes a cuboid frame structure, comprising four uprights, two bottom beams, two bottom beams, two top beams, and two top beams.
[0009] Preferably, the bottom reinforcement structure includes a thin steel plate, short square tubes and long square tubes. The four apex corners of the thin steel plate are cut with open square openings facing outwards, and the two sides of the symmetrical center width are cut with open rectangular openings facing outwards. Square tubes are evenly spaced from left to right on the thin steel plate, short square tubes are arranged on both sides and in the middle, and long square tubes are arranged in the rest.
[0010] Preferably, the enclosed inner support structure includes a front and rear inner support structure and a left and right inner support structure. The front and rear inner support structures each include a central square tube, a beveled square tube, and side steel plates. Beveled square tubes are fixedly installed on both sides of the central square tube. The central square tube is fixedly installed at the center of the front and rear sides of the frame basic structure. The beveled square tubes are connected and fixed at their inclined ends to the central square tube and bottom beam one and bottom beam two, respectively. The side steel plates are fixedly connected to the outer surfaces of the front and rear sides of the frame basic structure. The left and right inner support structures include end face steel plates, which are fixedly connected to the outer surfaces of the left and right sides of the frame basic structure.
[0011] Preferably, the bottom support includes a square tube and a steel plate. The steel plate is fixedly connected to the opening at the top of the square tube and is fixedly connected to the four corners at the bottom of the basic frame structure.
[0012] Preferably, the top support includes a square tube with a constricted opening, a square steel plate, and a second steel plate. The second steel plate is fixedly connected to the constricted end of the square tube with a constricted opening, and the other end of the square tube with a constricted opening is fixedly connected to the square steel plate. The square steel plate is fixedly connected to the four corners of the top of the frame's basic structure.
[0013] Preferably, the lifting lug is made of round steel bent into shape, with its long side fixed to the upper edge of the upright close to the side steel plate, and the bend facing downwards and outwards.
[0014] The beneficial effects of this utility model are: (1) The packaging box for the turnover of parts in the machinery manufacturing plant is convenient for the operators of the machinery equipment workshop to directly check the incoming materials according to the incoming material list, complete the manufacturing of the connecting parts and the acceptance and warehousing of the boxes, and improve the messy situation of the on-site manufacturing of connecting parts; (2) The packaging box for the turnover of parts in the machinery manufacturing plant has a simple structure and is easy to manufacture. It is made of carbon structural steel material with square tube as frame and steel plate as outer cover. Its strength is far greater than that of other disposable turnover boxes such as plywood. It has a large load capacity and can be used for a long time; (3) The packaging box for the turnover of parts in the machinery manufacturing plant can be nested in the bottom support of the upper layer and the top support of the lower layer through the bottom support of the upper layer. It can realize the nesting of the upper and lower packaging boxes, which is convenient for multi-layer stacking in height and effectively reduces the area used in the workshop and warehouse; (4) The packaging box for the turnover of parts in the machinery manufacturing plant can meet the lifting and handling of the steel wire rope and sling of the crane equipment in the machinery industry workshop, and can also meet the needs of the forklift equipment. (5) The packaging box for the turnover of parts in the machinery manufacturing plant has no top cover. During use, the actual height of the manufacturing connector is allowed to be moderately higher than the maximum height of the frame within the load-bearing range so as to maximize the loading capacity. (6) The bottom reinforcement structure of the packaging box for the turnover of parts in the machinery manufacturing plant has square tubes arranged at fixed distances in the extension direction on thin steel plates. This can strengthen the bottom plate strength, enhance the overall load-bearing capacity and overall stability of the box, and solve the problem of difficulty in taking out the manufacturing connectors with flat bottom surfaces such as steel plates in the box, so as to achieve the purpose of convenient take-out process.

Detailed Implementation
[0025] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:
[0026] Example: Figure 1 and Figure 2 As shown, a packaging box for the turnover of parts in a machinery manufacturing plant includes a basic frame structure 1, a bottom reinforcement structure 2, a closed inner support structure 3, bottom supports 4, top supports 5, and lifting lugs 6. It is used for the handling and inventory of flanges, elbows, tees, bolts, and other fasteners, small steel plates, small connecting pipes, and other parts during the workshop turnover process, collectively referred to as the handling and inventory of manufacturing connecting parts.
[0027] like Figure 3 As shown, the basic frame structure includes four vertical posts 1.1 at the four corners of a rectangular structure with a horizontal bottom surface. Two bottom beams 1.2 at the non-contacting bottom surface on both sides extend and connect to the two corner posts 1.1 respectively. Two bottom beams 1.3 at the non-contacting bottom surface on both sides extend and connect to the two corner posts 1.1 respectively. Two top beams 1.4 at the top surface contacting the top surface on both sides extend and connect to the two corner posts 1.1 respectively. Two top beams 1.5 at the top surface contacting the top surface on both sides extend and connect to the two corner posts 1.1 respectively. A 5.2mm thick square steel plate for top support is left between the top of the posts 1.1 and the top surface.
[0028] like Figure 4As shown, the bottom reinforcement structure 2 consists of a thin steel plate 2.1 with open square openings at its four apex and open rectangular openings at fixed points on both sides of its symmetrical center width, nested and fixed above two bottom beams 1.2 and 1.3. The short square tubes 2.2 and 2.3 are welded to the thin steel plate 2.1 using intermittent welding. The short square tubes 2.2 and 2.3 are arranged sequentially at fixed distances along their length, symmetrically positioned with their width center lines, and horizontally fixed at both ends to the thin steel plate 2.1. The three short square tubes 2.2 are fixed at the first, middle, and last positions along their length.
[0029] like Figure 5 As shown, the enclosed inner support structure 3 consists of two central square tubes 3.1 connected vertically end-to-end in the extension direction to the center lines of top beam 1.4, top beam 2.5, bottom beam 1.2, and bottom beam 2.3. The side steel plates 3.2 are fixed to the outer side of the frame basic structure 1 along its length with their four corners aligned. The end steel plates 3.3 are fixed to the outer side of the frame basic structure 1 along its width with their four corners aligned. The beveled square tubes 3.4 are connected and fixed at their angled ends to the central square tubes 3.1 and bottom beams 1.2 and 2.3, respectively.
[0030] like Figure 6 As shown, the bottom support 4 is symmetrically fixed to the center of the square tube 4.1 with its opening facing upwards and the steel plate 4.2 with an outer dimension larger than that of the square tube 4.1. The bottom support 4 is fixed to the four vertical poles at the four corners, and the steel plate 4.2 is horizontally fixed to the bottom of the pole 1.1.
[0031] like Figure 7 As shown, the top support 5 is fixed by a square tube 5.1 with its opening facing downwards and a square steel plate 5.2 with an outer dimension larger than that of the smaller square tube 5.1, forming an inner corner. After the upper end of the square tube 5.1 is beveled along the edge, the upper end is bent along the center horizontal line, and the upper side of the bevel forms a flared mouth, which is then closed and fixed at the top by steel plate 5.3. The top support 5 is fixed by forming a flat and closed structure between the upper end of the vertical pole 1.1 at the inner corner and the four corner positions, the top beam 1.4 and the ends of the top beam 1.5, with the square steel plate 5.2 horizontally attached.
[0032] like Figure 8 As shown, the lifting lug 6 is made by bending a round steel bar at an angle, and its long side is fixed to the upper edge of the side steel plate 3.2 of the upright, with the bend facing downwards and outwards. Except for the intermittent welding positions already specified above, all other fixed positions of the entire box body are welded along the weldable edge; except for the lifting lug welding height, which should not be less than the thickness of the thinner part, all weld heights should not be less than the thickness of the load-bearing thin steel plate. Each part is arranged according to... Figures 3 to 9 After manufacturing, it is assembled. Figure 1 Behind the box, all are arranged according to Figure 1 It is firmly welded and fixed, with no degree of freedom of displacement in any direction.
[0033] In use cases, such as Figure 4 As shown, the short square tube 2.2, the long square tube 2.3, and the thin steel plate 2.1 form the main load-bearing structure of the box. Various flanges, elbows, tees, bolts, and other fasteners, small steel plates, and small connecting pipes are placed on this structure according to the actual packing condition. While improving the overall load-bearing strength of the box, this structure creates a slot between the thin steel plate 2.1 and the short square tubes 2.2 and 2.3. This space allows lifting tools such as slings to pass under the manufacturing connectors located at the bottom of the box, such as steel plates and flanges, which are difficult to access, facilitating the direct and smooth lifting of these connectors. Figure 5 As shown, the enclosed internal support structure reinforces the box's strength from the side, increasing the overall volume of the box along its length and preventing the load from sliding out of the box at any angle. For example... Figure 6 As shown, the bottom support leg 4 can make Figure 3 The basic frame structure is raised to a certain height from the ground, providing space for commonly used forklift equipment to insert the forks into the bottom beam, enabling the box to be lifted and moved horizontally. For example... Figure 7 As shown, after the top support 5 is processed, a square tube with a constricted opening 5.1 is welded to a square steel plate 5.2 and then fixed to the top structure of the upright 1.1, which will then support the upper box body. Figure 6 The bottom support legs (4.1) are made of square tubing with the opening facing downwards and the four corners pointing downwards, accurately corresponding to the four apex corners of the lower box. The top support legs (5.1) are made of square tubing with a beveled opening, allowing for installation in empty or loaded conditions where the height does not exceed the height of a single box. Figure 9 The diagram shows a multi-layer stacking configuration. During stacking, the square tube 5.1 at the top support of the lower box has a bend at the end to facilitate linear and vertical guidance of the square tube 4.1 at the bottom support of the upper box into the nest. This bend provides sufficient dimensional allowance and spatial freedom for the square tube 4.1 at the bottom support of the upper box to accurately control its four-corner positioning and stacking on the top support 5 of the lower box, and is unaffected during the unloading of the upper box. Simultaneously, this structure effectively eliminates the displacement between the upper and lower boxes after stacking, ensuring stacking stability. Figure 8 As shown, lifting lug 6 is mainly used to lift the box directly from the top using wire ropes or slings when the box is not under load or the load is light.
[0034] The enclosure does not have a cover. If surface protection is required on-site, a rainproof tarpaulin or other fire-resistant material can be used to cover the top layer of the enclosure. If the on-site environment is poor and dust or water accumulates in the enclosure, drainage holes can be added to the thin steel plate 2.1 at the bottom reinforcement structure. For long-term use, the lifting lugs 6 should be inspected frequently. If the lifting lugs 6 show obvious deformation, they should be replaced promptly. If any welds on the enclosure come loose, they should be repaired promptly. If the enclosure is obviously deformed, it should be taken out of service.
[0035] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
