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] Most mainstream cage loading devices currently use a tilting structure. This structure has several drawbacks in practical applications. First, the center of gravity of the cage is easily unstable during the tilting process, which may cause the cage to tip over, leading to the scattering and damage of packages. In addition, tilting loading devices also have the problem of not being able to securely fix the cage, which may cause the cage to loosen or fall off during the tilting process.

[0032] To address the aforementioned technical problems, this utility model proposes a novel cage loading and unloading device, providing a loading and unloading solution that eliminates the need to flip the cages. This effectively solves problems such as unstable center of gravity, insecure fixing, and package tipping that exist in the prior art, thereby improving the safety and stability of loading and transportation.

[0033] Specifically, this invention introduces a lifting and translation mechanism to replace the flipping operation, thus avoiding the flipping of the cage. The design of the translation guide rail and translation trolley ensures smooth movement of the cage. After the lifting platform raises the cage to a predetermined height, the translation trolley supports the cage and moves back and forth along the translation guide rail, avoiding the problem of instability in the cage's center of gravity during the flipping operation.

[0034] Please refer to Figure 1 , Figure 2 and Figure 4 As shown, the cage loading and unloading device 100 in one embodiment of the present invention includes a translation mechanism 1 and a lifting mechanism 2. The translation mechanism 1 includes a first translation guide rail 11 and a translation trolley 12 disposed on the first translation guide rail 11. The translation trolley 12 includes a traveling component 13 and a lifting component 14. The traveling component 13 is used to drive the translation trolley 12 to move back and forth along the first translation guide rail 11. The lifting component 14 includes a lifting machine 141 and a pallet 142 disposed on the lifting machine 141. The lifting machine 141 is used to lift the pallet 142. The lifting mechanism 2 includes a lifting platform 21 disposed at the rear end of the first translation guide rail 11 for carrying the cage 200. The lifting platform 21 is provided with a second translation guide rail 22. The lifting platform 21 can be raised to be flush with the height of the first translation guide rail 11 so that the second translation guide rail 22 is connected to the first translation guide rail 11. When the second translation guide rail 22 is connected to the first translation guide rail 11, the translation trolley 12 can move along the second translation guide rail 22 to the lifting platform 21 and move to the bottom of the cage 200 supported on the lifting platform 21.

[0035] The first translation guide rail 11 extends in the front-to-back direction, providing a track for the translation trolley 12. The translation trolley 12 is mounted on the first translation guide rail 11 and mainly includes a traveling assembly 13 and a lifting assembly 14. The traveling assembly 13 drives the translation trolley 12 to move back and forth along the first translation guide rail 11. The traveling assembly 13 typically includes a motor, a drive shaft 134, and a wheel set. The motor drives the wheel set through the drive shaft 134, enabling the translation trolley 12 to move smoothly and precisely. The lifting assembly 14 includes a lifting mechanism 141 and a pallet 142. The lifting mechanism 141 raises and lowers the pallet 142, which is used to support and lift the cage 200. The lifting mechanism 141 can employ a hydraulic cylinder or an electric screw lifting system, which provides sufficient lifting force and precise control. The pallet 142 is typically made of high-strength materials and can be treated with anti-slip material to ensure that the cage 200 does not slip or tilt during lifting.

[0036] The lifting mechanism 2 is located at the rear end of the first translation guide rail 11 and is mainly used for supporting and lifting the cage 200. The lifting platform 21 is movably mounted at the rear end of the first translation guide rail 11. The design of the lifting platform 21 must consider load capacity and lifting stability, and typically employs a hydraulic or electric lifting system. The lifting platform 21 can be raised to the same height as the first translation guide rail 11 to achieve rail connection. The second translation guide rail 22 is mounted on the lifting platform 21. When the lifting platform 21 is raised to the same height as the first translation guide rail 11, the second translation guide rail 22 connects with the first translation guide rail 11. The function of the second translation guide rail 22 is to continue the movement trajectory of the translation trolley 12, ensuring that the translation trolley 12 can smoothly transition from the first translation guide rail 11 to the lifting platform 21.

[0037] When the loading operation begins, the traverse trolley 12 is initially positioned at the starting position of the first traverse guide rail 11. At this time, the lifting platform 21 is in a lower position (e.g., on the ground), which facilitates the transfer of the cage 200 onto the lifting platform 21. The second traverse guide rail 22 is not yet connected to the first traverse guide rail 11.

[0038] After the cage 200 is moved onto the lifting platform 21, the lifting mechanism 2 activates its lifting mechanism to smoothly raise the lifting platform 21 to the same height as the first translation guide rail 11. When the lifting platform 21 reaches the predetermined height, the second translation guide rail 22 is precisely connected to the first translation guide rail 11, ensuring that the translation trolley 12 can smoothly transition from the first translation guide rail 11 to the second translation guide rail 22 on the lifting platform 21.

[0039] Then, the traveling component 13 of the translation trolley 12 is activated, driving the translation trolley 12 forward along the first translation guide rail 11 until its front end connects with the second translation guide rail 22. Next, the translation trolley 12 continues to move smoothly along the second translation guide rail 22 to the lifting platform 21 until it is positioned at the bottom of the cage 200 supported on the lifting platform 21.

[0040] After the translating trolley 12 reaches the bottom of the cage 200, its lifting assembly 14 begins operation. The lift 141 starts, and the pallet 142 slowly rises to a position where it contacts the bottom of the cage 200 on the lifting platform 21, smoothly lifting the cage 200. The lifting action must ensure that the pallet 142 can fully contact the bottom of the cage 200 and remain stable throughout the lifting process to prevent the packages inside the cage 200 from shifting or tipping over. After the pallet 142 has fully lifted the cage 200 to the required height, the translating trolley 12 is ready to transport the cage 200 to the loading position.

[0041] After the translating trolley 12 lifts the cage 200, it returns along the second translating guide rail 22 and re-enters the first translating guide rail 11. At this time, the lifting platform 21 remains at the same height to ensure a smooth transition for the translating trolley 12. Driven by the traveling assembly 13, the translating trolley 12 moves along the first translating guide rail 11, transporting the lifted cage 200 to the designated loading position.

[0042] When the translating trolley 12 reaches the loading position, the lifting assembly 14 begins to lower the pallet 142, smoothly placing the cage 200 in the designated position. The lift 141 controls the pallet 142 to descend slowly, ensuring the cage 200 is placed smoothly and avoiding strong impacts or vibrations. After the pallet 142 is fully lowered, the translating trolley 12 can return to its initial position along the first translating guide rail 11, ready for the next loading and unloading operation.

[0043] In one exemplary embodiment, please refer to Figure 4 and Figure 5 As shown, the translation trolley 12 includes a chassis 121, and a walking assembly 13 is mounted on the chassis 121. The walking assembly 13 includes a walking wheel 131 and a walking drive motor 132. The walking wheel 131 is rotatably mounted on the chassis 121, and the walking drive motor 132 is connected to the walking wheel 131 to drive the walking wheel 131 to rotate.

[0044] The chassis 121 is the basic support structure of the translation trolley 12, bearing and supporting all other components. The chassis 121 is designed with high strength and rigidity, and can be made of high-strength steel or aluminum alloy to ensure it does not deform when bearing heavy loads. The size and shape of the chassis 121 can be optimized according to the needs of the entire device to ensure its smooth operation on the translation rails.

[0045] The traveling assembly 13 is the component that drives the translation trolley 12 to move along the guide rail. It is mounted on the chassis 121 and mainly includes traveling wheels 131 and a traveling drive motor 132. The traveling wheels 131 are rotatably mounted on the chassis 121 and can be made of wear-resistant, high-strength materials to ensure good grip and wear resistance on the guide rail. The traveling wheels 131 can be arranged in a four-wheel design to ensure the smooth operation of the translation trolley 12 on the guide rail.

[0046] The drive motor 132 is connected to the traveling wheel 131, driving the traveling wheel 131 to rotate. The selection of the motor must consider its output power and speed to ensure that the translation trolley 12 can move smoothly and quickly under different load conditions. A DC motor or an AC motor can be used, and a corresponding reducer mechanism can be configured to provide sufficient torque and control precision.

[0047] Specifically, the walking assembly 13 also includes a bearing housing 133 and a drive shaft 134. The bearing housing 133 is mounted on the chassis 121, and the drive shaft 134 is rotatably mounted on the bearing housing 133. The walking wheels 131 are mounted on the drive shaft 134. The bearing housing 133, mounted on the chassis 121, is used to fix the drive shaft 134. The drive shaft 134, rotatably mounted on the bearing housing 133, is connected to the walking wheels 131. The drive shaft 134 transmits rotational motion to the walking wheels 131 through a motor drive.

[0048] The drive motor 132 is connected to the wheel 131 via a drive shaft 134. The rotational motion of the motor is transmitted to the wheel 131 through the drive shaft 134, causing the wheel 131 to rotate. The drive shaft 134 can be made of high-strength steel to ensure that it does not deform or break during power transmission. Bearings can be installed at both ends of the drive shaft 134 to ensure low friction and high precision during rotation.

[0049] Furthermore, a reduction gear 135 is fixedly connected to the drive shaft 134, and a drive gear 136 is provided on the output shaft of the travel drive motor 132, which meshes with the reduction gear 135. The reduction gear 135 is fixedly connected to the drive shaft 134. Its main function is to reduce the speed of the motor output shaft through gear transmission, while increasing the output torque. The drive gear 136 is mounted on the output shaft of the travel drive motor 132, meshes with the reduction gear 135, and transmits the rotational motion of the motor to the reduction gear 135.

[0050] The rotational motion of the drive motor 132 is transmitted to the drive gear 136 via the output shaft. The drive gear 136 meshes with the reduction gear 135, transmitting the rotational motion to the reduction gear 135. The reduction gear 135 reduces the rotational speed and increases the torque through gear transmission, then transmits the rotational motion to the drive shaft 134. The reduction gear 135 is fixedly connected to the drive shaft 134, and its rotation drives the drive shaft 134 to rotate. The drive shaft 134 is supported and fixed by bearing seats 133 at both ends, ensuring stability and low friction during rotation. When the drive shaft 134 rotates, it drives the walking wheels 131 to rotate as well, and the rotation of the walking wheels 131 causes the translation trolley 12 to move on the guide rail.

[0051] In one exemplary embodiment, please refer to Figure 4 As shown, the outer circumferential surface of the traveling wheel 131 is recessed with a limiting groove 137 extending circumferentially along the traveling wheel 131. The first translation guide rail 11 and the second translation guide rail 22 are provided with limiting protrusions 111 that match the limiting groove 137. The limiting groove 137 and the limiting protrusions 111 are fitted together.

[0052] The outer circumferential surface of the traveling wheel 131 is recessed with a limiting groove 137, and the first translation guide rail 11 and the second translation guide rail 22 are provided with limiting protrusions 111 that match the limiting groove 137. The limiting groove 137 and the limiting protrusions 111 engage to ensure that the traveling wheel 131 will not derail when moving on the guide rail. This design increases the stability and safety of the translation trolley 12, and avoids equipment damage or operational interruption caused by derailment.

[0053] In one exemplary embodiment, please refer to Figure 4 and Figure 5 As shown, the lift 141 is mounted on the chassis 121. The lift 141 includes a worm gear lift 143 and a lift drive motor 144. The lifting rod 145 of the worm gear lift 143 is fixedly connected to the support plate 142. The lift drive motor 144 is connected to the worm gear lift 143 to drive the lifting rod 145 of the worm gear lift 143 to lift.

[0054] The worm gear jack 143 is the core component of the lifting assembly 14, responsible for raising and lowering the pallet 142. The worm gear jack 143 converts the rotary motion of the lifting drive motor 144 into the linear motion of the lifting rod 145 through the meshing of the worm and worm wheel. The lifting rod 145 is fixedly connected to the pallet 142, and its raising and lowering is achieved by the drive of the worm gear jack 143. The pallet 142 is fixed to the top of the lifting rod 145 and is used to support and lift the cage 200.

[0055] In one exemplary embodiment, please refer to Figure 1 , Figure 2 and Figure 3As shown, the translation mechanism 1 is equipped with a cage 200 guide rail 15 that matches the moving wheels at the bottom of the cage 200. The cage 200 guide rail 15 is used to limit the movement direction of the cage 200 when the translation trolley 12 transports the cage 200. The cage 200 guide rail 15 on the translation mechanism 1 matches the moving wheels at the bottom of the cage 200, ensuring that the cage 200 remains stable during transport by the translation trolley 12. The cage 200 guide rail 15 limits the movement direction of the cage 200, preventing it from deviating or tilting during transportation, thus improving the safety and reliability of the transportation process.

[0056] Specifically, frames 16 can be installed on the left and right sides of the translation mechanism 1, which can play a certain role in limiting and protecting the movement. The frames 16 form physical barriers on the left and right sides of the translation mechanism 1, effectively restricting the lateral movement of the cage 200. Through the limiting design, it is ensured that the cage 200 always stays on the set track during the translation process, avoiding violent collisions during the movement of the cage 200.

[0057] In one exemplary embodiment, please refer to Figure 1 , Figure 6 and Figure 7 As shown, the lifting mechanism 2 also includes a lifting guide rail 23, a connecting piece 24, a lifting screw 251 assembly 25, and a lifting motor 26. The lifting guide rail 23 is fixed to the rear end of the translation mechanism 1. The lifting screw 251 assembly 25 is disposed on the lifting guide rail 23. One end of the connecting piece 24 is connected to the lifting slider 252 of the lifting screw 251 assembly 25, and the other end is fixedly connected to the lifting platform 21. The lifting motor 26 is connected to the screw 251 of the lifting screw 251 assembly 25 to drive the screw 251 to rotate.

[0058] The lifting guide rail 23 can be fixed to the rear end of the translation mechanism 1, for example, to the rear end of the frame 16, providing a sliding path for the lifting screw 251 assembly 25 and the connector 24. The lifting guide rail 23 must be designed with sufficient strength and rigidity to ensure that it does not deform during lifting. The lifting screw 251 assembly 25 is mounted on the lifting guide rail 23 and includes a screw 251 and a lifting slider 252. The screw 251 is driven by the lifting motor 26, which drives the lifting slider 252 to move up and down along the lifting guide rail 23. The design of the lifting screw 251 assembly 25 must ensure that it can withstand large loads and remain stable and precise during lifting.

[0059] One end of the connector 24 is connected to the lifting slider 252 of the lifting screw 251 assembly 25, and the other end is fixedly connected to the lifting platform 21. The connector 24 is designed to have sufficient strength and rigidity to ensure that it does not deform when transmitting lifting force. The lifting platform 21 is used to support the cage 200 and is raised and lowered with the movement of the lifting screw 251 assembly 25.

[0060] The screw 251 of the lifting screw assembly 25 is connected to the lifting motor 26, and the rotation of the motor drives the screw 251 to rotate. The rotation of the screw 251 is converted into linear motion through threaded engagement with the lifting slider 252, driving the lifting slider 252 to move up and down along the lifting guide rail 23. The lifting slider 252 is connected to the lifting platform 21 through the connector 24, and the up and down movement of the lifting slider 252 is transmitted to the lifting platform 21 through the connector 24.

[0061] Specifically, the lifting slider 252 is equipped with rollers 253 that match the lifting guide rail 23. The rollers 253 are designed to reduce the friction between the lifting slider 252 and the lifting guide rail 23, making the movement of the slider on the guide rail smoother and more stable.

[0062] Please refer to Figure 8 As shown, one embodiment of this utility model also provides an unmanned vehicle 300, which includes the aforementioned cage loading and unloading device 100. Specifically, the cage loading and unloading device 100 is installed inside the carriage 310 of the unmanned vehicle 300, and the cage 200 can be loaded into the carriage 310 through the cage loading and unloading device 100.

[0063] In summary, the cage loading and unloading device and unmanned vehicle provided by this utility model introduce a lifting and translation mechanism to replace the flipping operation through the lifting mechanism and translation mechanism, thus avoiding the flipping operation of the cage; through the design of the translation guide rail and translation trolley, the cage can be moved smoothly; after the lifting platform raises the cage to the predetermined height, the translation trolley supports the cage and moves back and forth along the translation guide rail to load and unload the cage without flipping it, thereby avoiding the safety hazards and damage to the package during the flipping process.
