Description

Technical Field

[0001] This utility model belongs to the field of logistics and transportation technology, specifically relating to a cage loading and unloading device and an unmanned vehicle. Background Technology

[0002] With the rapid development of e-commerce, the demand for parcel transportation has increased dramatically. How to efficiently and safely transport and sort parcels has become a crucial issue for the logistics industry. During parcel transportation, sorted parcels are typically placed in cages and then transported and delivered by unmanned vehicles or other transportation tools. Existing cage loading devices mainly adopt a tilting structure. While this loading method can achieve automated loading, it has many problems in practical applications.

[0003] First, the operation of a tilting loading device requires tilting the cage, which inherently poses certain safety hazards. During tilting, the cage may become unstable or insecurely secured, easily causing packages inside to tip over, scatter, or even be damaged. This problem is particularly serious when loading packages with a high center of gravity, potentially causing the cage to tip over and posing a safety risk to the operator.

[0004] Secondly, the tilting loading device causes significant mechanical wear on the cage during loading. Frequent tilting operations not only easily lead to fatigue damage to the cage structure, but may also cause deformation of the cage due to collisions and friction during loading, affecting its normal service life. In addition, this loading method places high demands on the loading equipment itself, requiring sufficient mechanical strength and stability to cope with the enormous stress generated during tilting, which increases the manufacturing and maintenance costs of the equipment.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0031] Existing cage loading devices mainly employ a tilting structure. While this type of device can achieve automated loading, it has revealed several shortcomings in practical applications. The tilting loading device requires tilting the cage during operation, which poses certain safety hazards. During tilting, the cage may become unstable or insecurely secured, easily leading to the packages tipping over, scattering, or even being damaged. Furthermore, frequent tilting operations cause significant mechanical wear and tear on both the cage and the loading equipment, shortening their service life.

[0032] To address the aforementioned problems, this utility model proposes a novel cage loading and unloading device. Its design concept is to replace the existing flipping structure by adopting a combination of translation and lifting, thereby improving the safety, stability, and efficiency of the loading process.

[0033] Specifically, this invention improves operational safety by changing the loading process of the cage from flipping to translation and lifting. This avoids problems such as instability and insecure fixing that may occur during flipping. The translation and lifting operation reduces mechanical fatigue and wear caused by frequent flipping, extending the service life of the equipment and the cage. Furthermore, the translation and lifting method reduces impact on packages, especially fragile items, lowering the risk of damage during transportation and increasing the package integrity rate.

[0034] Please refer to Figure 1 and Figure 2 As shown, the cage loading and unloading device 100 in one embodiment of this utility model includes a translation mechanism 1 and a lifting mechanism 2. The translation mechanism 1 includes a translation guide rail 11, a translation slide 12, and a fork 13. The translation slide 12 is slidably disposed on the translation guide rail 11 and can slide back and forth along the translation guide rail 11. The fork 13 is fixed on the translation slide 12. The lifting mechanism 2 includes a fixed bracket 21, a pallet 22, a swing arm 23, a tilting drive 24, and a lifting drive 25. One end of the swing arm 23, the tilting drive 24, and the lifting drive 25 is hinged to the fixed bracket 21. The other end of the swing arm 23 and the tilting drive 24 is connected to the pallet 22, and the other end of the lifting drive 25 is hinged to the swing arm 23. The pallet 22 can be lifted to a height that allows the fork 13 to lift the cage 200 supported on the pallet 22 under the drive of the tilting drive 24 and the lifting drive 25.

[0035] The translation guide rail 11 restricts the sliding path of the translation slide table 12. It can be designed to be horizontally arranged to ensure that the slide table can slide smoothly and steadily on it. The guide rail material needs to have high strength and wear resistance. It can be made of metal materials such as steel or aluminum alloy to ensure long-term stability and durability.

[0036] The translation slide 12 is mounted on the translation guide rail 11 and can slide back and forth along the guide rail 11. The slide is equipped with a sliding mechanism (such as rollers or sliders) to reduce friction and improve sliding efficiency. The design of the translation slide 12 must consider load-bearing capacity to ensure smooth sliding when supporting the weight of the cage 200.

[0037] The fork 13 is fixed on the translation slide 12 and is used to support the cage 200. The fork 13 is designed with sufficient strength and rigidity to support the weight of the cage 200 and remain stable during translation. The number and layout of the fork 13 can be adjusted according to the size and weight of the cage 200 to ensure optimal support.

[0038] The fixed bracket 21 is the foundation of the entire lifting mechanism 2, providing connection and support for the other moving parts. The fixed bracket 21 needs to have high strength and stability, and can be made of steel to ensure that it will not deform or move during the lifting process.

[0039] The pallet 22 is the component that directly supports the cage 200. The lifting drive 25 and the tilting drive 24 work together to lift the cage 200. The pallet 22 is designed with load-bearing capacity and proper fit with the cage 200 in mind. It can be made of high-strength steel plate with an anti-slip surface to prevent the cage 200 from sliding during lifting. The width of the pallet 22 is less than the width of the cage 200, allowing the sides of the cage 200 to extend beyond the pallet 22, facilitating the lifting of the sides of the cage 200 by the forks 13.

[0040] One end of the swing arm 23 is hinged to the fixed bracket 21, and the other end is connected to the pallet 22. Driven by the tilting drive 24 and the lifting drive 25, the pallet 22 is lifted and its direction adjusted. The tilting drive 24, with one end hinged to the fixed bracket 21 and the other end connected to the pallet 22, drives the pallet 22 to rise by rotation. The tilting drive 24 can be a hydraulic cylinder or an electric push rod, and must have sufficient driving force to ensure that the pallet 22 can be tilted smoothly and accurately to the required angle. One end of the lifting drive 25 is fixed to the bracket, and the other end is hinged to the swing arm 23. The extension of the lifting drive 25 pushes the swing arm 23 upward, thereby raising the pallet 22 and adjusting its direction to ensure that the pallet 22 remains horizontal during lifting, preventing the cage 200 from tilting or moving.

[0041] Before loading begins, pallet 22 is in its lowest position, and fork 13 is positioned at the predetermined loading position of the cage 200 to be loaded. At this time, the tilting drive 24 and lifting drive 25 of the lifting mechanism 2 are in standby mode, ready to proceed with the next action. The operator sends a lifting signal through the control system, and the tilting drive 24 and lifting drive 25 respond to the signal and begin synchronous operation. As the tilting drive 24 and lifting drive 25 operate, pallet 22 gradually rises until it reaches the predetermined height (this height is set so that the fork 13 can insert below the cage 200 on pallet 22). At this point, the cage 200 on pallet 22 is at a suitable height and position to be lifted by the fork 13.

[0042] Then, the translation mechanism 1 is activated, and the translation drive system begins to work, moving the fork 13 to below the pallet 22 to lift the cage 200. Subsequently, the lifting drive 25 and the tilting drive 24 are controlled to slowly lower the pallet 22. The lifting drive 25 and the tilting drive 24 work synchronously to ensure that the pallet 22 remains horizontal during descent. During this process, the fork 13 gradually contacts the bottom of the cage 200 and supports it, preparing for the next step of translation. Once the cage 200 is stabilized by the fork 13, the translation mechanism 1 is activated again, and the translation slide 12, carrying the fork 13 and the cage 200, moves along the translation guide rail 11 towards the loading position.

[0043] In one exemplary embodiment, please refer to Figures 1 to 3 As shown, the front end of the translation guide rail 11 is pivotally connected to a laterally extending first drive shaft 111, and a drive sprocket 112 is provided on the first drive shaft 111; the rear end of the translation guide rail 11 is pivotally connected to a laterally extending second drive shaft 113, and a driven sprocket 114 is provided on the second drive shaft 113. The drive sprocket 112 and the driven sprocket 114 are connected by a drive chain 115, and the drive chain 115 is connected to the translation slide 12.

[0044] The translation guide rail 11 can be configured as two parallel guide rails extending forward and backward. A first drive shaft 111 extending laterally (left-right direction) is pivotally connected to the front end of the translation guide rail 11. The first drive shaft 111 is mainly used to mount the drive sprocket 112. The first drive shaft 111 can be mounted on the end of the translation guide rail 11 via bearings to ensure its smooth rotation.

[0045] The drive sprocket 112 is fixed on the first transmission shaft 111 and is responsible for transmitting power. Power can be transmitted to the driven sprocket 114 via the transmission chain 115. The number of teeth and diameter of the drive sprocket 112 can be designed according to the transmission ratio requirements to ensure the smooth operation of the translation slide 12.

[0046] A second, laterally extending drive shaft 113 is pivotally connected to the rear end of the translation guide rail 11, and a driven sprocket 114 is mounted on the second drive shaft 113. Similar to the first drive shaft 111, the second drive shaft 113 is also mounted on the end of the guide rail via bearings to ensure stable rotation. The driven sprocket 114 is fixed to the second drive shaft 113 and connected to the drive sprocket 112 via a drive chain 115. The number of teeth and diameter of the driven sprocket 114 match those of the drive sprocket 112 to ensure that the transmission ratio between them meets the design requirements. The drive chain 115 is connected to the translation slide 12, and the movement of the chain drives the slide to slide along the translation guide rail 11. Rollers or sliders are mounted on the translation slide 12 to ensure smooth sliding of the slide on the guide rail.

[0047] Specifically, the translation mechanism 1 also includes a translation drive 14 and a chain drive assembly 15. The translation drive 14 is connected to the first drive shaft 111 via the chain drive assembly 15. The translation drive 14 is a key component that provides power and can be an electric motor or a hydraulic motor. The translation drive 14 is connected to the first drive shaft 111 via the chain drive assembly 15, transmitting power to the drive sprocket 112, thereby driving the operation of the entire transmission system.

[0048] In one exemplary embodiment, please refer to Figure 4 As shown, the translation slide 12 includes a base 121, a translation roller 122, a mounting bracket 123, and an adjusting bolt 124. The mounting bracket 123 is fixed to the bottom of the base 121. The translation roller 122 is rotatably connected to the mounting bracket 123 and slidably mounted on the translation guide rail 11. The adjusting bolt 124 is screwed onto the translation roller 122 and the mounting bracket 123 to adjust the lateral position of the translation roller 122.

[0049] The base 121 is the main body 231 of the translation slide 12 and bears the main load-bearing function. The base 121 can be made of high-strength steel or aluminum alloy to ensure that it has sufficient strength and rigidity to withstand the weight of the cage 200 and its dynamic load during the sliding process.

[0050] The translation roller 122, made of wear-resistant material, is mounted on the bottom of the base 121. The movement of the slide table on the guide rail is achieved by the rolling of the translation roller 122. The mounting bracket 123 is fixed to the bottom of the base 121 to support the translation roller 122. The mounting bracket 123 can be made of steel, possessing good strength and durability. The design of the mounting bracket 123 must ensure that the translation roller 122 can be stably mounted on it and achieve smooth rolling.

[0051] Adjusting bolt 124 is screwed onto the translation roller 122 and the mounting bracket 123 to adjust the lateral position of the translation roller 122. By adjusting bolt 124, the position of the roller relative to the guide rail can be precisely adjusted to ensure smooth sliding of the translation slide 12 on the guide rail.

[0052] Specifically, please refer to Figure 1 and Figure 2 As shown, a mounting plate 16 is fixedly provided on the base 121. The mounting plate 16 extends laterally to both sides of the base 121. The fork tooth 13 includes tooth plates 131 respectively fixed to both sides of the mounting plate 16.

[0053] Mounting plate 16 is fixed to base 121 and extends laterally to both sides of base 121. This design allows mounting plate 16 to provide stable support for fork tines 13. Mounting plate 16 can be made of high-strength steel, possessing good strength and durability. The design of mounting plate 16 must ensure that it can be firmly connected to base 121 and provide sufficient space and support to accommodate and secure fork tines 13.

[0054] The fork 13 includes toothed plates 131 respectively fixed to both sides of the mounting bracket 123. These toothed plates 131 are fixed to the mounting plate 16 by welding or bolting, ensuring that they can firmly support the weight of the cage 200. The toothed plates 131 are the main load-bearing parts of the fork 13 and can be made of high-strength steel. The toothed plates 131 are designed to have sufficient thickness and strength to prevent deformation or breakage when supporting the cage 200. The surface of the toothed plates 131 can be treated with anti-slip coating to increase friction with the cage 200 and prevent the cage 200 from sliding during loading and unloading.

[0055] Specifically, the spacing of the tooth plates 131 of the fork 13 matches the spacing of the moving wheels at the bottom of the cage 200. A support block 132 is protruding on the upper surface of the tooth plate 131 so that when the fork 13 lifts the cage 200, the moving wheels of the cage 200 can be supported on the tooth plate 131, and the bottom of the cage 200 can be supported on the support block 132.

[0056] The spacing between the toothed plates 131 matches the spacing of the moving wheels at the bottom of the cage 200, ensuring that the moving wheels can be stably supported on the toothed plates 131 during lifting. Support blocks 132 protrude from the upper surface of the toothed plates 131 to provide additional support. When the fork 13 lifts the cage 200, the moving wheels of the cage 200 can be supported on the toothed plates 131, while the bottom of the cage 200 can be supported on the support blocks 132. The design of the support blocks 132 must consider their height and position to ensure effective support of the bottom of the cage 200 during lifting, preventing it from tilting or sliding.

[0057] Furthermore, the upper surface of the mounting plate 16 is provided with a baffle 17 for preventing the cage 200, which is supported on the fork 13, from sliding. The baffle 17 prevents the cage 200 from sliding during lifting and moving. The baffle 17 can be made of a high-strength material and has good wear resistance and impact resistance.

[0058] In one exemplary embodiment, please refer to Figure 1 , Figure 5 and Figure 6 As shown, the swing arm 23 of the lifting mechanism 2 includes a main body 231 and an extension 232. One end of the main body 231 is hinged to the fixed bracket 21, and the extension 232 bends and extends from the other end of the main body 231. The end of the extension 232 is hinged to the support plate 22.

[0059] The extension 232 bends and extends from the other end of the main body 231, and its end is hinged to the pallet 22 via a hinge. The design of the extension 232 allows the swing arm 23 to provide support while also flexibly adjusting the angle and position of the pallet 22, ensuring that the pallet 22 remains horizontal during lifting and lowering.

[0060] One end of the main body 231 is hinged to the fixed bracket 21, allowing the swing arm 23 to rotate freely on the fixed bracket 21. The design of the hinge mechanism must ensure that it has good rotational freedom and load-bearing capacity to meet the movement requirements of the swing arm 23 during the lifting process.

[0061] Specifically, the tilting drive 24 is a tilting hydraulic cylinder, and the lifting drive 25 is a lifting hydraulic cylinder. The end of the hydraulic rod of the lifting hydraulic cylinder is hinged to the connection between the main body 231 and the extension 232 so that the pallet 22 remains horizontal during the lifting process.

[0062] Please refer to Figure 7 As shown, one embodiment of this utility model also provides an unmanned vehicle 300, which includes a carriage 310 and the aforementioned cage loading and unloading device 100. Specifically, the translation mechanism 1 of the cage loading and unloading device 100 is installed inside the carriage 310, and the lifting mechanism 2 of the cage loading and unloading device 100 is installed at the rear of the carriage 310. Through the cooperation of the lifting mechanism 2 and the translation mechanism 1 of the cage loading and unloading device 100, cages 200 can be loaded into the carriage 310, or cages 200 inside the carriage 310 can be unloaded.

[0063] In summary, the cage loading and unloading device and unmanned vehicle provided by this utility model can adjust the height of the cage through the lifting operation of the lifting mechanism, so that the cage can be lifted to a predetermined position and move horizontally in coordination with the translation mechanism to complete the loading operation without flipping the cage, thereby avoiding the safety hazards and damage to the package during the flipping process.
