Description

Technical Field

[0001] This utility model relates to the field of logistics pallet technology, and in particular to a splicing logistics pallet. Background Technology

[0002] On the one hand, the splicing flexibility is insufficient. Most traditional pallets are integral structures and cannot be flexibly combined according to the size of the goods. When it is necessary to transfer oversized or irregularly shaped goods, it is difficult to form a suitable bearing surface by splicing multiple pallets. If they are forcibly stacked or spliced, the goods are prone to tilting and falling due to unstable connection, which increases the transportation risk. Although some splicable pallets can achieve basic combination, the splicing points lack multiple fixing structures, which are prone to loosening in handling or vibration environments, affecting the overall stability. On the other hand, the functions of mobility and fixation are not coordinated. Although wheeled pallets are convenient for short-distance movement, the connection structure between the wheels and the pallet is often not reliable enough. The wheel frame is prone to displacement due to load or collision, causing the pallet to wobble during movement. While wheelless pallets are stable, they rely on forklifts and other equipment for handling, which increases operating costs and time. The anti-slip performance of the bearing surface of traditional pallets is poor. Goods are prone to slipping due to insufficient friction when being transferred or placed at rest. The risk of goods slipping is significantly increased, especially in tilted or vibrating scenarios.

[0003] Furthermore, it is difficult to balance the stability and convenience of component connections. Existing pallet designs, such as wheel frame fixing and splicing locking, are complex, and the installation and disassembly process is time-consuming and laborious, which is not conducive to quickly adjusting the pallet status to adapt to different operational needs. Some connecting components lack buffering or fastening structures, and after long-term use, they are prone to connection failure due to wear, which shortens the service life of the pallet.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a splicing logistics pallet, including a splicable pallet 1, the edge of which has a flange 12 and a groove 13 for interlocking assembly, and different flanges 12 and grooves 13 can be used to fix and connect the splicable pallet 1. The bottom of the modular pallet 1 has four wheel frame slots 11, and each wheel frame slot 11 is movably connected to two buckles 7; A fixing slot 9 is provided on the wheel frame groove 11. The fixing slot 9 is used for the fixed connection between the wheel frame groove 11 and the splicable tray 1. Two buckles 7 are movably connected around each wheel frame groove 11 and play an important role. Each buckle 7 is fitted into the fixing slot 9 on the wheel frame groove 11 to ensure the fixed connection between the wheel frame groove 11 and the splicable tray 1. Each buckle 7 has a slot 10 around it, and a fastening washer 8 is fixedly connected to the side wall of the slot 10. When the buckle 7 is not needed, the buckle 7 can be nested into the slot 10. The fastening washer 8 serves to fix the buckle 7, so that the buckle 7 is firmly fixed in the slot 10. A modular wheel frame 3 is fixedly connected to the wheel frame groove 11, and a wheel 4 is rotatably connected to the modular wheel frame 3. This connection allows the wheel 4 to rotate freely, thereby realizing the movement function of the entire pallet. A locking block 5 is fixedly connected to the side of the modular pallet 1. A connecting pin 6 is movably connected to the locking block 5. The two ends of the connecting pin 6 are respectively fixed to the locking block 5 on the side of the modular pallet 1 by insertion, so as to further fix the modular pallet 1. The modular pallet 1 is fixedly connected with an anti-slip pad 2. The anti-slip pad 2 fixedly connected to the modular pallet 1 can increase the friction between the pallet surface and the placed items, effectively preventing the items from sliding on the pallet and improving the safety of the pallet during use.

[0017] Working principle: First, the splicing and fixing of the pallets. The flange 12 and groove 13 on the edge of the splicable pallet 1 are the key to achieving basic splicing. Different splicable pallets 1 are embedded into the groove 13 through the flange 12 to form a preliminary interlocking assembly, realizing the splicing of multiple pallets. In order to further enhance the stability after splicing, the locking block 5 fixedly connected to the side of the splicable pallet 1 and the connecting pin 6 movablely connected play their role. When the two ends of the connecting pin 6 are inserted into the locking block 5 on the side of the adjacent splicable pallet 1, the pallets that have been spliced ​​by the flange 12 and groove 13 can be fixed a second time, effectively preventing the splicing joint from loosening. Secondly, the installation and fixing of the wheels 4 are as follows: the four wheel frame slots 11 under the modular pallet 1 are used to install the modular wheel frame 3. The fixing slots 9 on the wheel frame slots 11 ensure a fixed connection between the wheel frame slots 11 and the modular pallet 1, so that the wheel frame slots 11 are firmly located under the modular pallet 1. The modular wheel frame 3 is fixedly connected to the wheel frame slots 11, and the wheels 4 are rotatably connected to the modular wheel frame 3. This connection allows the wheels 4 to rotate freely, thereby realizing the movement function of the entire pallet. Regarding the securing of the wheel frame, two latches 7 movably connected around each wheel frame groove 11 play a crucial role. Each latch 7 fits into a fixing slot 9 opened on the wheel frame groove 11, ensuring a fixed connection between the wheel frame groove 11 and the connectable tray 1. When the buckle 7 is not needed, the buckle 7 can be nested into the slot 10, where the fastening washer 8 serves to fix the buckle 7, so that the buckle 7 is firmly fixed in the slot 10. In addition, the anti-slip pads 2 fixedly connected to the splicable pallet 1 can increase the friction between the pallet surface and the placed items, effectively preventing items from sliding on the pallet and improving the safety of the pallet during use.

[0018] To further improve the disclosed technical solution and enable those skilled in the art to fully understand the structural details, material selection, performance parameters, and installation and maintenance points of the modular logistics pallet, supplementary explanations are provided in the following aspects: I. Core Design of the Main Structure and Splicing System: 1. Material and dimensions of the modular pallet 1: The pallet body is injection molded from high-density polyethylene (HDPE) (with 15% glass fiber reinforcement). Each pallet measures 1200mm × 1000mm × 150mm (length × width × height). The bottom has nine reinforcing ribs (50mm × 30mm cross-section) forming a grid-like load-bearing structure. Static load capacity is ≥3000kg, and dynamic load capacity is ≥1500kg (when handled by forklift). The pallet surface flatness error is ≤2mm / m to ensure stable placement of goods (tilt angle ≤1°).

[0019] The edge flange 12 is a rectangular structure (100mm×50mm×20mm), which forms a clearance fit with the groove 13 (102mm×52mm×22mm) (1mm clearance on one side). The flange surface is machined with 0.5mm deep serrations (5mm spacing), which cooperate with the rubber strip (Shore hardness 60°) on the inner side of the groove to increase the splicing friction (pull-in and pull force ≥800N) and prevent loosening during transportation.

[0020] 2. Fitting accuracy of the splicing and locking structure: Locking blocks 5 are made of PP material (integrated injection molded with the pallet). Two blocks are installed on the long side of each pallet (600mm spacing) and one block is installed on the short side. The dimensions of a single locking block are 80mm×50mm×30mm, and it has an internal pin hole of φ12mm (40mm depth). The connection between the locking block and the pallet is reinforced with a reinforcing rib (10mm thickness), with a shear strength ≥15MPa.

[0021] Connecting pin 6 is made of 45# steel tempered rod (12mm diameter, 200mm length), with a chrome-plated surface (20μm thickness) for corrosion resistance. Both ends are machined with 3mm deep annular grooves (5mm spacing) to engage with elastic retaining balls (3mm diameter) in the locking block pin holes. After insertion, the clamping force is ≥50N, ensuring no axial movement after splicing (movement ≤0.5mm). A single connecting pin can withstand a tensile force of ≥500N, meeting the overall strength requirements after splicing multiple pallets.

[0022] II. Core parameters of the mobile system: 1. The synergistic design of the connectable wheel frame 3 and wheels 4: The wheel frame is made of die-cast aluminum alloy (ADC12) and measures 150mm × 100mm × 80mm. It is fixed in the wheel frame groove 11 by four M8 bolts (preload 20N・m). The distance between the bottom of the wheel frame and the bottom of the pallet is 50mm (to ensure that the forklift forks can be inserted). The connecting shaft between the wheel frame and the wheel is a φ10mm stainless steel shaft (304 material), fitted with a deep groove ball bearing (model 6200), with a rotational resistance ≤10N (single wheel).

[0023] The wheels are made of polyurethane (PU) (100mm in diameter, 30mm in width), with a nylon core (PA6 + 30% glass fiber). The load capacity is ≥500kg / wheel (total load capacity of 4 wheels ≥2000kg). The wheel surface is machined with 2mm deep anti-slip grooves (herringbone pattern), with a friction coefficient ≥0.8 (on concrete surfaces). Braking is achieved through brake pads (rubber material) on the wheel frame (braking force ≥200N).

[0024] 1. The fixing mechanism between wheel frame groove 11 and buckle 7: The wheel frame groove is rectangular (160mm×110mm×30mm) with four φ10mm bolt holes at the bottom (for wheel frame fixing). The fixing slot 9 is L-shaped (30mm×20mm×15mm), forming an interference fit with the buckle 7 (28mm×18mm×14mm) (0.1mm interference on one side). The buckle is made of spring steel (65Mn) (2mm thickness), with an elastic deformation ≤5mm. After fastening, the pressure on the wheel frame is ≥100N, ensuring no lateral displacement of the wheel frame (displacement ≤0.3mm).

[0025] The fastening gasket 8 inside the slot 10 is made of nitrile rubber (2mm thick), with a Shore hardness of 70°. The clearance between the gasket and the buckle is ≤0.1mm. When the buckle is retracted, the friction of the gasket is ≥30N, preventing the buckle from shaking and making abnormal noise when the vehicle is in motion (noise ≤60dB).

[0026] 2. Wheel frame removal and switching function: When forklift handling is required, the steps to disassemble the wheel frame are as follows: press the clip 7 to disengage it from the fixing slot 9 → unscrew the fixing bolts → remove the wheel frame. The entire process can be completed by one person in ≤1 minute (60% more efficient than traditional wheeled pallets). The bottom of the wheel frame slot 11 is equipped with a positioning pin (8mm in diameter and 5mm in height), which mates with the positioning hole on the wheel frame. The alignment accuracy during installation is ≤1mm, ensuring that the perpendicularity error of the wheel after installation is ≤0.5mm / m.

[0027] III. Details of the anti-slip and safety system: 1. Performance parameters of anti-slip pad 2: The gaskets are made of nitrile rubber (Shore hardness 75°), measuring 100mm × 100mm × 5mm. They are bonded to the pallet surface using epoxy resin adhesive (shear strength ≥ 5MPa) (in a 5×4 array). The gasket surface is machined with 2mm deep diamond-shaped patterns (10mm spacing). The coefficient of friction between the gasket and the goods is ≥ 0.8 (dry state) and ≥ 0.6 (wet state), effectively preventing goods from sliding (goods do not slide at a 15° tilt angle). The gaskets have an aging resistance life of ≥ 3 years (in an environment of -30℃ to 70℃) and can be replaced individually (replacement time ≤ 30 seconds / gasket).

[0028] 2. Safety protection design: All edges and corners of the pallet are rounded (10mm radius) to prevent scratches to operators or goods during handling (compliant with GB / T2934-2007 standard). The wheels are equipped with mudguards (PP material, 30mm high) to prevent ground debris from getting into the axle; The connection between the wheel frame and the tray is reinforced with a 5mm thick plate, which has an impact resistance of ≥20kJ / m² (can withstand the impact of a 10kg weight falling from a height of 1m).

[0029] IV. Load-bearing capacity and applicable scope: 1. Load capacity in different scenarios: 1. Applicable types of goods: This pallet is suitable for packaging all types of goods. For boxed goods (such as cardboard boxes and wooden crates): anti-slip pads are used to prevent slipping. For bagged goods (such as flour and feed): splicing them together forms a large load-bearing surface to avoid localized deformation under pressure. For irregularly shaped goods (such as pipes and plates): the size can be adjusted by splicing multiple pallets and secured with straps (the pallet edge has 4 strap holes, 20mm in diameter).

[0030] V. Installation and Maintenance Requirements: 1. Wheel frame installation and adjustment: When installing the wheel frame, ensure that there are no foreign objects in the wheel frame groove 11, align the positioning pin with the wheel frame hole (deviation ≤ 1mm), and tighten the bolts evenly (diagonally). After the wheels are installed, their rotational flexibility must be tested (rotation 360° without jamming), and the perpendicularity of the wheel frame to the tray must be checked (error ≤ 1mm / m). Before first use, a full-load test (loading 1.2 times the rated load) must be performed, and after running for 500 meters, check that all components are not loose.

[0031] 1. Regular maintenance items: Weekly: Clean dust and debris from the wheel frame grooves; check if the connecting pins are loose (there should be no obvious wobbling when you pull them by hand); Monthly: Add lithium-based grease to the wheel axle bearing (2g each time); check the wear of the anti-slip pads (replace when the wear depth is ≥1mm); Quarterly: Test the strength of the interlocking blocks (use a tension gauge to test the connecting pin tension ≥500N); check the wear of the wheels (replace when the diameter decreases by ≥5mm).

[0032] 1. Common faults and solutions: VI. Performance Comparison with Traditional Pallets: This device solves the problems of poor adaptability, inconvenient movement, and insufficient anti-slip properties of traditional pallets through its innovative design of modular splicing, detachable wheel frame, and high-efficiency anti-slip. It is particularly suitable for scenarios such as e-commerce warehouses and manufacturing workshops where pallet size and movement paths need to be frequently adjusted, providing an efficient and flexible solution for logistics turnover.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
