Description

Technical Field

[0001] This utility model relates to the field of boiler packaging technology, specifically to a boiler component packaging box and its frame structure. Background Technology

[0002] During boiler transportation, boiler components typically require certain forms of packaging. These packaging methods include: wooden crates, primarily suitable for products with relatively small dimensions or low individual weight; iron crates, mainly suitable for relatively small (length less than or equal to 1m) or low individual weight and valuable products, and also for products that are numerous, easily lost, and unsuitable for wooden crates; and frames, mainly suitable for components with large lengths, small cross-sections, low weight, and no requirements for waterproofing or moisture protection. Relevant standards stipulate that the main frame should be made of channel steel or other profiles, depending on the packaging quality. The bottom and four sides can be partitioned with smaller channel steel or angle steel, or enclosed with wire mesh. The length should ideally be 3m to 6m.

[0003] As the export volume of boiler products gradually increases, the packaging of irregularly shaped boiler parts exported to overseas markets is usually transported by international sea. International sea freight costs are generally calculated based on the volume of the boiler parts packaging. Therefore, to reduce transportation costs, the packaging volume of exported irregularly shaped boiler parts should be reasonably and effectively reduced. Since the shapes and structures of irregularly shaped boiler parts are often irregular and numerous, the industry typically pre-fabricates packaging boxes or frames of a certain size, and then places the boiler parts into the packaging boxes according to requirements.

[0004] The current packaging frame for irregularly shaped boiler components has the following problems: (1) When all the irregularly shaped boiler components are placed into the packaging box, it is found that the packaging box is not full. Since the packaging box has already been made, the structure cannot be changed according to the actual height, resulting in wasted space inside the packaging box and increased international shipping costs. (2) When it is found that the height of the irregularly shaped boiler components inside the packaging box is greater than the height of the pre-made packaging box, the height of the original packaging box needs to be temporarily increased on site according to the actual situation, thereby increasing the amount of packaging materials and welding work, and affecting the appearance quality of the packaging.

[0005] For example, CN216995411U discloses an adjustable packaging box, including a bottom assembly, side assemblies, a back assembly, a side-pressure assembly, and a backrest assembly. The bottom assembly includes a first length adjustment part with adjustable length. There are two side assemblies, each disposed on one side of the bottom assembly. The side assemblies are fixed relative to the first length adjustment part, and each side assembly includes a first height adjustment part with adjustable height. Although this disclosed technology solves the problem of adjustable packaging box height to some extent, it still suffers from poor overall structural strength, and because the diagonal supports are slidably mounted on two adjacent rods, the diagonal supports are difficult to slide automatically with the automatic extension and retraction of the vertical rods, and the height adjustment is limited by the fixed length of the diagonal support rods. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of this utility model is to provide a boiler component packaging box and its frame structure.

[0007] According to the present invention, a boiler component packaging box frame structure includes a first telescopic rod, a second telescopic rod, and a crossbar.

[0008] Multiple first telescopic rods are connected vertically and parallel to each other between two crossbars. A hinge plate is provided at the diagonal position of two adjacent first telescopic rods. The two ends of the second telescopic rod are connected to the hinge plate in a hinged manner. The structure formed by connecting the first telescopic rods, the second telescopic rods and the crossbars is an adjustable support frame. Multiple adjustable support frames are connected to form a polygonal packaging box frame.

[0009] In some embodiments, the number of adjustable support frames is four, and the four adjustable support frames are connected to form a rectangular packaging box frame.

[0010] In some embodiments, the number of the first telescopic rods in the adjustable support frame is ≥3.

[0011] In some embodiments, adjacent second telescopic rods in the adjustable support frame form a V-shaped structure.

[0012] In some embodiments, a drive cylinder is also included, which drives the first telescopic rod connected to the edge of the packaging box frame, and the drive cylinder drives the first telescopic rod to extend and retract axially.

[0013] In some embodiments, the drive cylinder is a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0014] In some embodiments, a bidirectional self-locking mechanism is also included, which includes a ratchet and a pawl. The ratchet is rotatably connected to the hinge plate, and the two ends of the second telescopic rod are respectively connected to two ratchets at diagonal positions and rotate synchronously with the ratchets. The pawl is used to lock and limit the ratchet.

[0015] This utility model also provides a boiler component packaging box, which adopts the aforementioned boiler component packaging box frame structure.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The boiler component packaging box structure provided in this embodiment uses a second telescopic rod, which also has a telescopic function, hinged at a diagonal position on the adjustable support frame. The second telescopic rod can extend, retract, and rotate simultaneously with the extension and retraction of the first telescopic rod, ensuring that the height of the packaging box frame structure is adjustable and increasing the adjustment range. At the same time, the two ends of the second telescopic rod are supported at the top corner of the adjustable support frame, which not only strengthens the structural strength of the packaging box, but also further improves the tightness of the packaged boiler components, saves packaging space, and reduces international sea freight logistics costs.

[0023] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0024] This embodiment provides a boiler component packaging box frame structure, such as... Figure 1-4 As shown, the packaging box frame is a polygonal frame structure formed by connecting multiple adjustable support frames 100. In this embodiment, four sets of adjustable support frames 100 are connected to form a rectangular frame structure for illustration.

[0025] like Figure 1 As shown, the adjustable support frame 100 is mainly composed of a first telescopic rod 1, a second telescopic rod 2, and a crossbar 3 connected together. Specifically, multiple first telescopic rods 1 are connected vertically and parallel to each other between the upper and lower crossbars 3 to form a rectangular frame. Figure 1 Taking the example shown, five first telescopic rods 1 are evenly spaced between the upper and lower crossbars 3. The two ends of each first telescopic rod 1 are detachably connected to the connecting rod 31 of the two crossbars 3. This detachable connection is achieved through a socket and a pin. A socket is provided at the end of the connecting rod 31, and the two ends of the first telescopic rod 1 are convex structures. The two ends of the first telescopic rod 1 are inserted into the socket of the connecting rod 31, and then locked by a pin to achieve the detachable connection. A hinge plate 32 is provided at the diagonal position of the rectangular frame formed by two adjacent first telescopic rods 1 and the upper and lower crossbars 3. The hinge plate 12 has a fan-shaped structure and is located in the angled structure formed by the connecting rod 31 and the crossbars 3. The two ends of the second telescopic rod 2 are rotatably connected to the hinge plate 12 by hinges, meaning that the end of the second telescopic rod 2 hinged to the hinge plate 32 can rotate along its hinge point. This embodiment provides a bidirectional self-locking mechanism 5, such as... Figure 2-4 As shown, it mainly includes a ratchet 51 and a pawl 52. The ratchet 51 is rotatably connected to the hinge plate 32. The two ends of the same second telescopic rod 2 are respectively connected to two ratchet 51s at diagonal positions and can rotate synchronously with the ratchet 51. The pawl 52 is used to lock and limit the ratchet 51. When it is necessary to raise or lower the adjustable support frame 100, taking the raising as an example, firstly, the pawl 52 is opened, and the second telescopic rod 2 extends as the upper and lower crossbars 3 move away from each other. While the body of the second telescopic rod 2 extends, its two ends rotate counterclockwise with the ratchet 51. After reaching the predetermined height, the pawl 52 is lowered and locks the ratchet 51, so that the second telescopic rod 2 supports the crossbar 3. One second telescopic rod 2 is set between every two adjacent first telescopic rods 1. In some embodiments, when the number of first telescopic rods 1 connected between two crossbars 3 is greater than or equal to 3, two adjacent second telescopic rods 2 within the same adjustable support frame 100 form a V-shaped structure. This V-shaped structure includes an inverted V-shaped structure with the opening facing downwards. See [link to relevant documentation]. Figure 1 As shown, the second telescopic rod 2, which serves as a diagonal bracing structure, forms a V-shaped structure, which can improve the load-bearing capacity of the adjustable support frame 100 in both the vertical and horizontal directions, thereby increasing the strength of the packaging box frame structure.

[0026] The boiler component packaging box structure provided in this embodiment uses a second telescopic rod, which also has a telescopic function, hinged at a diagonal position on the adjustable support frame. The second telescopic rod can extend, retract, and rotate simultaneously with the extension and retraction of the first telescopic rod, ensuring that the height of the packaging box frame structure is adjustable and increasing the adjustment range. At the same time, the two ends of the second telescopic rod are supported at the top corner of the adjustable support frame, which not only strengthens the structural strength of the packaging box, but also further improves the tightness of the packaged boiler components, saves packaging space, and reduces international sea freight logistics costs.

[0027] In some embodiments, to improve the degree of automation in the height adjustment of the packaging box frame, a drive cylinder 4 is provided on the first telescopic rod 1 where the edge of the packaging box frame is located. The installation method of the drive cylinder 4 can be referred to Figure 1 As shown, the first telescopic rod 1 is installed between two connecting plates, one of which is connected to the rod body of the first telescopic rod 1, and the other is installed on the connecting rod 31. The first telescopic rod 1 is axially extended and retracted by the drive cylinder 4, thus adjusting the height of the packaging box frame. The drive cylinder 4 is installed on the edges of the packaging box frame only to ensure smooth axial extension and retraction of the first telescopic rod 1; it is not necessary to install a drive cylinder 4 on every edge. For example, in a rectangular packaging box frame, only two drive cylinders 4 need to be installed at diagonal positions, saving costs. The drive cylinder 4 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.
