Description

Technical Field

[0001] This utility model relates to the field of logistics and supply chain management, and in particular to a cargo transfer vehicle for logistics transportation. Background Technology

[0002] In the logistics and transportation sector, freight transfer vehicles are key equipment connecting different modes of transport (such as from truck to rail or air). Traditional freight transfer vehicles are typically designed as universal models to accommodate goods of various sizes and types.

[0003] However, with the rapid development of the logistics industry, logistics demand has exploded, and the requirements for transportation efficiency, safety, and cost control have become increasingly stringent. The limitations of traditional general-purpose freight transfer vehicles have gradually become apparent, severely restricting the further development of the logistics transportation industry.

[0004] When transporting fragile goods (such as glassware, precision instruments, and ceramic handicrafts), traditional transfer vehicles lack specific protective measures and cannot effectively buffer against bumps, vibrations, and collisions during transportation. Goods on transfer vehicles are easily subjected to external impacts, leading to breakage, cracks, or even complete destruction of the fragile items inside, causing huge economic losses to logistics companies and cargo owners.

[0005] Therefore, there is a need to provide a cargo transfer vehicle for logistics transportation. Utility Model Content

[0006] To overcome the shortcomings of lacking buffer function, this utility model provides a cargo transfer vehicle for logistics transportation.

[0007] A cargo transfer vehicle for logistics transportation includes a chassis, wheels, a connecting frame, and protective doors. Wheels are provided at the four corners of the bottom of the chassis, and a connecting frame is provided at the top of the chassis. Protective doors are symmetrically installed on the upper front side of the connecting frame via hinges. The vehicle also includes a buffer assembly, which is provided at the bottom inside the connecting frame.

[0008] Further explanation: The buffer assembly includes a dual-axis motor, a take-up drum, a fixing rod, a strap, and a limiting block. Springs are evenly distributed and connected at the bottom of the connecting frame, with a bearing plate between the tops of the springs. Dual-axis motors are symmetrically mounted longitudinally on the top of the connecting frame, each with a take-up drum on its output shaft. A fixing rod is symmetrically mounted longitudinally on the bottom of the connecting frame, with winding wheels at both its front and rear ends. A strap is mounted on the take-up drum on the front left side, with the other end extending downwards and passing through the top of the connecting frame, winding... The other end of the strap extends past the winding wheel on the front side of the fixed rod and passes through the three limiting blocks on the front side. It then goes around the winding wheel on the front side of the fixed rod, and finally the other end of the strap on the front side is connected to the take-up drum on the right front side. There is also a strap on the take-up drum on the left rear side. The other end of the strap extends downward and passes through the top of the connecting frame, and goes around the winding wheel on the rear side of the fixed rod. The other end of the strap continues to extend past the three limiting blocks on the rear side, and goes around the winding wheel on the rear side of the fixed rod, and finally the other end of the strap on the rear side is connected to the take-up drum on the right rear side.

[0009] To further explain, it also includes a connecting plate, which connects the two straps together.

[0010] To further explain, it also includes a vibration sensor, which is installed in the middle of the top of the connecting frame.

[0011] To further explain, it also includes a humidity sensor, which is installed on the right side wall of the connecting frame.

[0012] To further clarify, the top of the support plate is coated with an anti-slip coating.

[0013] To further clarify, the wheels are swivel wheels.

[0014] To further explain, the connection between the fixing rod and the strap uses a winding wheel as the connecting component.

[0015] The beneficial effects and significant advancements of this utility model are as follows:

[0016] This invention uses a dual-axis motor to drive the winding drum to rotate, enabling the tightening and loosening of the straps. This allows for flexible adjustment of the straps' fixing force on the goods according to their size and weight, ensuring stability during transport and preventing slippage or displacement. The design of springs and bearing plates buffers and absorbs vibrations and impacts on the goods during transport, reducing damage caused by bumps. Attached Figure Description

Detailed Implementation

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] Example: A cargo transfer vehicle used for logistics transportation. Please see below. Figures 1 to 6As shown, the vehicle includes a base frame 1, wheels 2, a connecting frame 3, a protective door 4, a load-bearing plate 5, a spring 6, a dual-axis motor 7, a winding drum 8, a fixing rod 9, straps 10, a limit block 11, a connecting plate 12, a vibration sensor 13, and a humidity sensor 14. The base frame 1 serves as the main support structure of the entire cargo transfer vehicle, bearing and securing other components. Wheels 2 are connected to the four corners of the bottom of the base frame 1; these wheels are omnidirectional for easy steering and mobility, enabling the cargo transfer vehicle to move flexibly at different transport nodes and achieve rapid cargo transfer. A connecting frame 3 is connected to the top of the base frame 1, providing installation positions for other components and forming the main spatial framework for cargo placement. The upper front of the connecting frame 3 is symmetrically secured by hinges. The connecting frame 3 is equipped with a protective door 4, which closes the front opening of the frame. Springs 6 are evenly distributed throughout the bottom of the frame. These springs absorb and disperse vibration energy, reducing the impact on the goods and thus lowering the risk of damage and improving transport safety. A bearing plate 5 is connected between the tops of the springs 6. The top of the bearing plate 5 is coated with an anti-slip material to increase friction between the goods and the top of the bearing plate 5, providing an anti-slip effect. The bearing plate 5 directly supports the goods, and the elastic support of the springs 6 provides it with a certain buffering capacity. A dual-axis motor 7 is symmetrically mounted longitudinally on the top of the connecting frame 3. The output shafts of the dual-axis motor 7 are connected to a winding drum 8, which rotates symmetrically longitudinally within the bottom of the connecting frame 3. There are two fixing rods 9, with winding wheels rotatably connected to their front and rear ends. A strap 10 is connected to the take-up drum 8 on the left front side. The connection between the fixing rods 9 and the strap 10 uses winding wheels as connectors, which reduces the friction between the strap 10 and the fixing rods 9. The other end of the strap 10 extends downward and passes through the top of the connecting frame 3, and goes around the winding wheel on the front side of the fixing rod 9. The other end of the strap 10 continues to extend and passes through the three limiting blocks 11 located on the front side, goes around the winding wheel on the front side of the fixing rod 9, and finally the other end of the strap 10 on the front side is connected to the take-up drum 8 on the right front side. A strap 10 is also connected to the take-up drum 8 on the left rear side. The strap 10 is used to fix the goods and prevent them from sliding, shifting or tipping over during transportation. The other end of the strap 10 extends downward. The strap 10 extends through the top of the connecting frame 3, passes around the winding wheel behind the fixing rod 9, and continues through the three limiting blocks 11 located at the rear, passing around the winding wheel behind the fixing rod 9. Finally, the other end of the strap 10 is connected to the take-up drum 8 on the right rear side. The take-up drum 8 is driven to rotate by the dual-axis motor 7 to tighten and loosen the strap 10. This allows for flexible adjustment of the strap 10's fixing force on the goods according to their size and weight, ensuring the goods remain stable during transport and preventing slippage or displacement. The two straps 10 are connected together by a connecting plate 12. A vibration sensor 13 is installed in the middle of the top of the connecting frame 3. The vibration sensor 13 is used to monitor the vibration of the transport vehicle during transportation in real time.A humidity sensor 14 is installed on the right side wall of the connecting frame 3 to monitor the humidity environment inside the connecting frame 3 in real time.

[0026] When a cargo transfer vehicle is needed, first place it on a flat, solid surface. Avoid using it on uneven, soft, or obstructed surfaces to prevent the vehicle from becoming unstable or overturning. Depending on the cargo transportation needs, move the transfer vehicle to a position where it can dock with trucks, railway cars, or aircraft cargo holds, ensuring that the docking area has sufficient space for loading and unloading cargo.

[0027] Hold the handles of the protective door 4 with both hands and slowly pull them outwards to fully open the protective door 4. Use a forklift, crane or other loading and unloading equipment to carefully place the goods on the load-bearing plate 5, and try to keep the center of gravity of the goods in the center of the load-bearing plate 5 to avoid the goods being unbalanced and causing the transfer vehicle to be unstable.

[0028] Adjust the placement of goods on the support plate 5 according to their shape and size to ensure adequate gaps between them and prevent them from being squeezed or collided. For fragile items or precision instruments, cushioning materials such as foam boards or sponges can be placed between goods or between goods and the inner wall of the connecting frame 3.

[0029] The motor is started, causing the take-up drum 8 to rotate. The dual-axis motor 7 simultaneously drives the left and right take-up drums 8 to rotate synchronously, gradually tightening the straps 10. During the tightening process, the securing of the goods is closely observed. The securing force of the straps 10 is flexibly adjusted according to the size, weight, and shape of the goods by controlling the running time of the dual-axis motor 7. This ensures the goods are securely fixed without excessive compression to avoid damage. When the straps 10 have firmly secured the goods and the connecting plate 12 is tightly fitted to the surface of the goods, the dual-axis motor 7 is stopped.

[0030] During the transport process, the vibration sensor 13 is connected to a display device or alarm device so that the vibration sensor 13 continuously monitors the vibration of the transport vehicle and transmits the data to the display device.

[0031] If the vibration data exceeds the set safety range, the display device will issue an alarm. At this time, the driving status of the transfer vehicle should be checked immediately, such as whether it has encountered uneven road surfaces or sudden braking. Adjust the transport speed according to the actual situation, choose a smoother route, and if necessary, stop to check the securing of the goods and whether all components of the transfer vehicle are functioning properly to prevent damage to the goods due to excessive vibration.

[0032] Connect the humidity sensor 14 to the display device to view the humidity data inside the connection frame 3. If the humidity exceeds the suitable range required for cargo transportation, such as when the cargo is sensitive to humidity and excessive humidity may cause the cargo to become damp or moldy, dehumidification measures should be taken immediately. For example, place a desiccant inside the connection frame 3 or turn on the equipped dehumidification equipment to reduce the humidity inside the connection frame 3 and ensure that the cargo is transported in a suitable humidity environment.

[0033] Upon arrival at the destination, move the cargo transfer vehicle to the unloading location, such as the truck bed or next to warehouse shelves, ensuring that the unloading area is spacious and easy to operate.

[0034] The dual-axis motor 7 is reversed to make the winding drum 8 rotate in the opposite direction, and the strap 10 is gradually loosened. When the strap 10 is completely loosened, hold the handle of the protective door 4 with both hands and slowly pull it outward to fully open the protective door 4 and provide enough space for unloading the goods.

[0035] Using a forklift, crane, or other loading and unloading equipment, carefully unload the goods from pallet 5 and place them in the designated location. Handle with care during unloading to avoid collisions or damage.

[0036] After the goods are unloaded, hold the handle of the protective door 4 with both hands and slowly push it inward to close the protective door 4. Make sure the protective door 4 is closed tightly. When the cargo transfer vehicle is no longer needed, store the cargo transfer vehicle in the designated location.
