[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Generally speaking, when designing a tray, it is necessary to consider the shape and structure of the product, the placement requirements, and the transportation safety. There are relatively few types and models of axle housing parts, and the shape and structure, the number and size of holes of each model are different. In addition, the flange surface is a machined surface with high precision requirements and is not allowed to be knocked or damaged. In addition, in order to reduce the recycling cost, it is required to load as many trays as possible for return journey at one time.

[0023] For the selection of the square tubes in this embodiment, the weight of the axle housing parts to be carried needs to be considered. 5# square tubes can be selected. 5# square tubes are a specification of square tubes, usually referring to square tubes with a side length of 50 mm. Square tubes are a kind of square or rectangular hollow steel. Of course, the selection of square tubes is not limited to 5# square tubes, and can be selected according to the specific weight to be carried and the structure.

[0024] The welding methods of the square tubes in this embodiment include but are not limited to the following methods. The middle of the tray uses a welding method with inward inclination of square tubes, enabling the cast surfaces of different arc surfaces in the middle of the product to be safely and stably placed on the tray, thus expanding the scope of use of the tray.

[0025] Shielded Metal Arc Welding (SMAW): This is a traditional welding method that uses a manual arc electrode for welding. It is suitable for welding in various positions, but requires a high level of skill from the operator.

[0026] Gas Metal Arc Welding (GMAW / MIG / MAG): Welding is carried out using a continuously fed welding wire and a shielding gas. It is suitable for welding carbon steel, stainless steel, and low alloy steel, with a fast welding speed and good weld appearance.

[0027] Gas Tungsten Arc Welding (GTAW / TIG): Welding is carried out using a non-consumable tungsten electrode and argon as the shielding gas. It is suitable for welding non-ferrous metals such as stainless steel, aluminum, and magnesium, with high welding quality but a relatively slow speed.

[0028] Submerged Arc Welding (SAW): Welding is carried out under a flux cover using a continuously fed welding wire. It is suitable for welding thick materials, with high production efficiency but limited welding positions.

[0029] Resistance Spot Welding (RSW): Welding is carried out using resistance heat and is divided into spot welding and seam welding. It is suitable for welding thin sheet materials, with a fast welding speed and little heat affected zone.

[0030] Oxyfuel Welding: Welding is carried out using a combustible gas (such as acetylene or propane) and oxygen. It is suitable for welding cast iron and some non-ferrous metals, but the welding quality is not as good as arc welding. Laser Welding: Welding is carried out using a high-energy density laser beam. It is suitable for precision welding, with an extremely small heat affected zone and a fast welding speed, but the equipment cost is high.

[0031] Electron Beam Welding (EBW): Welding is carried out using a high-speed electron beam as the heat source. It is suitable for welding with high quality requirements, such as in the aerospace field, with a fast welding speed and a small heat affected zone, but the equipment is complex and expensive. Friction Welding: Welding is carried out using the heat generated by mechanical friction. It is suitable for materials that are difficult to weld, such as titanium alloys, with high-quality welded joints.

[0032] Ultrasonic Welding: Welding is carried out using the heat generated by ultrasonic vibration. It is suitable for welding plastics and some metals, without a melting process, and the welding quality is stable.

[0033] Explosion Welding: Welding is carried out using the energy generated by an explosion. It is suitable for welding large areas of dissimilar metals, such as composite plates of stainless steel and carbon steel. In this embodiment, the above method can be adopted to achieve the connection of steel pipes.

[0034] In this embodiment, the material of the square tube can have the following options. When selecting the material of the square tube for the transport tray of the axle housing parts, the following factors need to be considered:

[0035] Load-bearing capacity: The square tube needs to have sufficient strength and rigidity to support the weight of the axle housing parts and the dynamic loads that may be encountered during transportation.

[0036] Durability: Select materials that are corrosion-resistant and wear-resistant to ensure the stability and reliability of the square tube during long-term use.

[0037] Cost-effectiveness: Select materials with high cost performance under the premise of meeting technical requirements to control costs.

[0038] Workability: Consider the workability of the square tube material to ensure that processing operations such as cutting, welding, and forming can be conveniently carried out. Environmental adaptability: Select materials with strong adaptability according to the transportation and storage environment (such as temperature, humidity, chemical corrosion, etc.).

[0039] Weight: If it is necessary to reduce the overall weight of the pallet, materials with low weight but high strength, such as aluminum alloy, can be considered.

[0040] Aesthetic appearance: For some applications, there may be certain requirements for the appearance. Select materials with good surface treatment and uniform color.

[0041] Recyclability: Considering environmental protection factors, select recyclable materials to reduce the impact on the environment.

[0042] Compliance with standards: Ensure that the selected materials comply with industry standards and safety specifications, such as ISO or ASTM standards.

[0043] Special performance requirements: If the axle housing parts need special protection during transportation, such as anti-static and anti-magnetic, select square tube materials with corresponding characteristics.

[0044] Common square tube material selections include: Carbon steel: Q235, Q345, etc., suitable for general load-bearing requirements and with high cost-effectiveness. Stainless steel: 304, 316, etc., suitable for environments with higher corrosion resistance requirements. Aluminum alloy: Has a lower density and good corrosion resistance, suitable for occasions where weight reduction is required. High-strength alloy steel: Suitable for special occasions with extremely high load-bearing capacity requirements.

[0045] In this embodiment, there can also be multiple choices for the thickness and diameter of the square tube. The thickness and diameter of the square tube have a significant impact on its performance, which is specifically manifested in the following aspects:

[0046] Load-bearing capacity: As the wall thickness of the square tube increases, its load-bearing capacity also increases. Thick-walled square tubes can withstand greater pressure and loads and are suitable for occasions that bear large mechanical stresses. Rigidity: The larger the diameter and wall thickness of the square tube, the better its rigidity, which means that under the same load, the deformation is smaller, and it is more suitable for structures that need to maintain shape stability.

[0047] Stability: Larger diameters and wall thicknesses can enhance the stability of square tubes, reducing bending and distortion under load. Durability: Square tubes with greater wall thickness generally have a longer service life as they are more resistant to wear, corrosion, and other forms of degradation.

[0048] Weight: An increase in the diameter and wall thickness of square tubes leads to an increase in weight, which may affect the costs and convenience of transportation and installation.

[0049] Cost: Generally speaking, the greater the wall thickness, the higher the cost of square tubes, as more materials and potentially more complex manufacturing processes are required.

[0050] Thermal conductivity: The wall thickness of square tubes has an impact on their thermal conductivity. Square tubes with larger wall thicknesses may not be as efficient in heat conduction as thin-walled square tubes.

[0051] Weldability: The thickness of square tubes affects their weldability. Thick-walled square tubes may require special welding techniques and longer welding processes.

[0052] Workability: The diameter and wall thickness of square tubes affect their workability. Thicker walls may require more force and more complex tools for processing, such as cutting, drilling, or bending. Designers may select square tubes of different sizes according to the specific requirements of the project to achieve the desired visual effects. When designing and selecting square tubes, it is necessary to comprehensively consider the diameter, wall thickness, and other performance indicators of square tubes based on specific application requirements and budgets to achieve the best performance and economic benefits.

[0053] In this embodiment, the tray body includes a base (1) and side plates (7). A support seat (2) is provided at the middle position of the base (1) for carrying parts. The support seat (2) is composed of welded square tubes. An inclined square tube (13) is provided in the middle of the support seat (2) for fixing parts. A protective strip (10) is provided on the surface of the square tube on the support seat (2) that contacts the parts.

[0054] A column (11) is provided on the front side of the support seat (2). The column (11) is fixed to the base (2) by welding. A support tube (12) is fixed on one side of the column (11). A protective strip (10) is provided on one side of the column (11). The protective strip is a fixing material added at the positions on the tray that contact the parts to protect the flange surface and other easily knocked parts of the parts from being damaged during hoisting and transportation. Two fixing beams (3) are provided at the positions on both sides of the base (2). The fixing beams (3) are concave beams composed of square tubes and are used on both sides of the tray. The square tubes are welded into a concave support structure, mainly for supporting, and secondly for fixing and restricting workpieces. A protective strip (10) is provided above the fixing beam (3).

[0055] The positioning frame (6) is composed of square tubes and is used to position parts. A support tube (12) is provided on one side of the positioning frame (6), and a protective strip (10) is provided above the positioning frame (6).

[0056] Fixing materials are added at the positions on the tray that come into contact with the parts to protect the flange surfaces and other easily bumped areas of the parts from being damaged during hoisting and transportation. For example, nylon plates with a thickness of 20 mm are used. Packing buckles are welded around the tray to fix the parts.

[0057] For the material of the protective strip in this embodiment, it can also include but is not limited to the following options. The material of the protective strip of the protection device can be selected according to its application scenario and required performance. The following are some common materials:

[0058] Plastic: Lightweight and low-cost, commonly used for protective strips of daily necessities, such as anti-collision strips on the edges of furniture. Rubber: Has good elasticity and wear resistance, suitable for occasions that require buffering and sealing, such as door and window sealing strips.

[0059] Silicone: Resistant to high and low temperatures, good chemical stability, commonly used for the sealing and protective strips of electrical products. Metal: Such as stainless steel, aluminum alloy, etc., has high strength and durability, suitable for protective strips that bear heavy loads or need to withstand greater forces.

[0060] Nylon: Wear-resistant and good self-lubricating performance, commonly used for protective strips of mechanical moving parts.

[0061] Polytetrafluoroethylene (PTFE): Also known as Teflon, has excellent chemical corrosion resistance and non-stick properties, suitable for protective strips in high-temperature and corrosion-resistant environments.

[0062] Polyurethane (PU): Has good wear resistance and elasticity, commonly used for anti-collision strips and buffer strips of industrial equipment.

[0063] PVC: Chemically corrosion-resistant and low-cost, commonly used for protective strips in building and pipe systems.

[0064] ABS plastic: Has good mechanical properties and processing performance, commonly used for manufacturing various protective strips and edge protection.

[0065] Fiberglass-reinforced plastic (FRP): Has high strength and corrosion resistance, suitable for protective strips in outdoor and harsh environments.

[0066] Carbon fiber: Lightweight and high-strength, commonly used for lightweight protective strips of high-end products.

[0067] Four conical upper feet (8) are welded at the four corners on the upper side of the side plate, and four lower feet (9) with a slope are welded at the four corners on the lower side. Four trapezoidal feet with a slope are welded at the four corners under the tray, and conical cylinders are welded at the four corners on the upper side. In this way, the trays can be stacked on top of each other, improving the space utilization rate during product shipping and return transportation and reducing transportation costs.

[0068] A crossbar (5) is designed at the lower end of the base. A protective strip (10) is provided on the contact surface of the square tube in the middle of the side plate (7). Several packing buckles (4) are fixed on both sides of the support seat (2).

[0069] Regarding the selection of packing buckles, including but not limited to the following methods. When selecting the packing buckle (4) for the transportation tray of bridge shell parts, the following key factors should be considered:

[0070] Material strength: The packing buckle needs to bear the weight of the bridge shell parts and the impact force that may occur during transportation. Therefore, it is necessary to select a material with high strength. Metal materials such as steel or aluminum alloy can be selected, as these materials have good load-bearing capacity and durability.

[0071] Durability and corrosion resistance: The packing buckle (4) should have good durability and be able to resist wear during daily use. In addition, if the transportation environment may come into contact with moisture or chemical substances, it is also important to select corrosion-resistant materials such as stainless steel or metal buckles with anti-corrosion coatings.

[0072] Operation convenience: The design and operation method of the packing buckle (4) should be simple and fast, facilitating workers to quickly pack and unpack, and improving logistics efficiency.

[0073] Adaptability: The packing buckle (4) should be applicable to trays of different sizes and shapes to ensure that the bridge shell parts can be firmly fixed. According to these factors, a packing buckle suitable for bridge shell parts can be selected to ensure safety and reliability during transportation.

[0074] The tray in this embodiment is assembled by welding square tubes and steel plates, leaving enough space below to facilitate the operation of forklifts.

[0075] Now, a second embodiment is designed. In the second embodiment, the upper feet (8) and lower feet (9) are not designed, and the inclined square tube (13) is not provided. Without the upper and lower feet, after transporting the bridge shell parts, the tray needs to be recycled. However, this tray cannot be stacked, or if separated by wooden boards, it will cause the trays to collide with each other, affecting the tray structure. The second embodiment does not provide an inclined square tube.

[0076] Since the inclined square tube (13) is not provided in the second embodiment, the bridge shell parts are prone to displacement in the lateral direction and thus fall to one side, which is not conducive to transportation safety.

[0077] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
