[0036] Reference Figures 1 to 7 As shown, one embodiment of the present invention provides a cage loading and unloading device, which includes a base plate 2, a lifting component 3, and a translation component 4.

[0037] Specifically, the base plate 2 is used to be installed on the unmanned transport vehicle. The base plate 2 can support the carriage 1 for accommodating the cage 5. After the cage 5 enters the carriage 1, the base plate 2 can support the cage 5 from the bottom. The lifting assembly 3 is located on the side of the base plate 2. The lifting assembly 3 includes a liftable first support part 31, which can support the cage 5 from the bottom. The translation assembly 4 is located on the top of the base plate 2. The translation assembly 4 includes a movable translation part 41 and a second support part 44 located on the translation part 41. The second support part 44 can also be lifted and can also support the cage 5 from the bottom.

[0038] The first support unit 31 has a first working position and a second working position with different heights, wherein the height of the first working position is lower than that of the base plate 2 and is approximately close to the ground where the unmanned transport vehicle is located, and the height of the second working position is higher than that of the translation unit 41.

[0039] The translation unit 41 has a third working position and a fourth working position located at different horizontal positions. The third working position is relatively close to the lifting assembly 3. When the translation unit 41 moves to the third working position, a portion of the translation unit 41 and the second support part 44 extend outward from the base plate 2 and are suspended in the air, so that the portion of the translation unit 41 extending outward from the base plate 2 can cooperate with the first support part 31 located at the second working position to transfer the cage 5. The fourth working position is relatively far away from the lifting assembly 3 and corresponds to the position of the cage 5 on the base plate 2.

[0040] When the cage loading and unloading device is in the loading state, the first supporting part 31 moves to the first working position. Workers manually or mechanically move the cage 5 to the first supporting part 31. The first supporting part 31 then moves upwards to the second working position, raising the cage 5 above the translation part 41. Next, the translation part 41 moves to the third working position, causing the second supporting part 44 to move below the cage 5 on the first supporting part 31. The second supporting part 44 moves upwards to contact the cage 5, raising it a certain distance so that the cage 5 detaches from the first supporting part 31 and is transferred to the second supporting part 44. Subsequently, the translation part 41 moves to the fourth working position, and the second supporting part 44 moves downwards to lower the height of the cage 5, causing the bottom legs of the cage 5 to contact the bottom plate 2, thereby transferring the cage 5 onto the bottom plate 2.

[0041] When the cage loading and unloading device is in the unloading state, the translation part 41 moves to the fourth working position, and the second bearing part 44 moves upward, lifting the cage 5 carried on the bottom plate 2. Next, the translation part 41 moves to the third working position, the first bearing part 31 moves to the second working position, and the second bearing part 44 moves downward. After the cage 5 it carries comes into contact with the first bearing part 31, it can detach from the second bearing part 44 and transfer to the first bearing part 31. Subsequently, the translation part 41 retracts inward to avoid the first bearing part 31, and the first bearing part 31 moves downward to the first working position, transferring the cage 5 to a position close to the ground.

[0042] In addition, it should be noted that when the base plate 2 has a sufficient area to support multiple cages 5, the translation part 41 also has an additional fifth working position and a sixth working position. These additional working positions are located between the third working position and the fourth working position and correspond one-to-one with the placement position of the cages 5.

[0043] The structure of lifting component 3 will be further described below.

[0044] In one embodiment, reference is made to Figure 5As shown, the lifting assembly 3 also includes a first guide rail 33 and a lifting part 34. The first guide rail 33 is disposed on the side of the base plate 2 and extends approximately vertically. The lifting part 34 is disposed on the first guide rail 33 and can move along the first guide rail 33. A first support part 31 is disposed on the lifting part 34. When the lifting part 34 moves along the first guide rail 33, the height of the first support part 31 can be changed, so that the first support part 31 can move between a first working position and a second working position.

[0045] Furthermore, the lifting unit 34 includes a first side plate, a second side plate, and a third side plate. The first side plate and the second side plate are arranged opposite each other in the horizontal direction and are located on both sides of the first guide rail 33, respectively. The third side plate connects the first side plate and the second side plate.

[0046] The first guide rail 33 has a first guide groove 331 on both sides facing the first side plate and the second side plate. The first side plate and the second side plate are provided with a first roller 35 that cooperates with the first guide groove 331 on the side facing the first guide rail 33. The rotation axis of the first roller 35 is parallel to the groove opening direction of the first guide groove 331.

[0047] When the lifting part 34 moves along the first guide rail 33, the first roller 35 contacts the lateral groove wall of the first guide groove 331 and rolls along the groove wall, reducing the friction between the lifting part 34 and the first guide rail 33 and reducing the resistance of the lifting part 34.

[0048] In one embodiment, the lifting assembly 3 further includes a lifting transmission mechanism connected to the lifting part 34. The lifting transmission mechanism includes, but is not limited to, a chain transmission mechanism, a screw transmission mechanism, a gear and rack transmission mechanism, a lead screw and nut transmission mechanism, a hydraulic / pneumatic lifting transmission mechanism, a scissor-type lifting transmission mechanism, and an electromagnetic lifting transmission mechanism. Any transmission mechanism that can change the height of the lifting part 34 can be used as a lifting transmission mechanism.

[0049] Optionally, the lifting transmission mechanism is a chain transmission mechanism, which includes two sprockets with a height difference and a chain that drives the two sprockets. A certain part of the chain is fixedly connected to the lifting part 34, so that the lifting part 34 can drive the lifting part 34 to rise and fall synchronously with it.

[0050] In one embodiment, reference is made to Figure 5 As shown, the lifting assembly 3 also includes a tilting shaft 32 connected to the first support part 31. The axial direction of the tilting shaft 32 is approximately perpendicular to the moving direction of the first support part 31 and the moving direction of the second support part 44. The first support part 31 can be tilted around the tilting shaft 32. When the cage loading and unloading device completes the cage loading or unloading work, the first support part 31 can be tilted upwards and retracted.

[0051] Furthermore, the lifting assembly 3 also includes a tilting transmission mechanism disposed on the lifting part 34. The tilting transmission mechanism is connected to the tilting shaft 32 and is used to drive the tilting shaft 32 to rotate. The tilting transmission mechanism includes, but is not limited to, chain transmission mechanism, belt transmission mechanism, gear transmission mechanism and linkage transmission mechanism. Any transmission mechanism that can drive the tilting shaft 32 to rotate can be used as the tilting transmission mechanism.

[0052] Optionally, the reversing transmission mechanism is a chain transmission mechanism, which includes a driving sprocket, a driven sprocket and a chain. The driving sprocket is connected to a drive element (e.g., a motor), the driven sprocket is connected to the reversing shaft 32, and the chain is in transmission cooperation with the driving sprocket and the driven sprocket.

[0053] In one embodiment, reference is made to Figure 4 and Figure 5 As shown, the first support portion 31 is generally constructed as a long strip structure extending in a straight line, and the shape of the first support portion 31 is similar to the fork arm of a forklift. There are two of each of the first guide rail 33, lifting portion 34 and first support portion 31, and the two first support portions 31, two first guide rails 33 and two lifting portions 34 are provided in a one-to-one correspondence with each other.

[0054] The structure of translation component 4 will be further described below.

[0055] In one embodiment, reference is made to Figures 6 to 9 As shown, the translation component 4 includes two second guide rails 42 and a plurality of second rollers 43. The two second guide rails 42 are arranged opposite to each other and both extend along the moving direction of the translation part 41. The plurality of second rollers 43 are respectively arranged on opposite sides of the two second guide rails 42.

[0056] Furthermore, the translation part 41 is constructed as a rectangular frame structure. The translation part 41 is located between two second guide rails 42. The sides of the translation part 41 facing the second guide rails 42 are provided with second guide grooves 411 that cooperate with the second rollers 43. The second rollers 43 can support the translation part 41, so that there is a certain gap between it and the base plate 2. The second rollers 43 can also reduce the friction between the translation part 41 and the second guide rails 42, and reduce the resistance of the translation part 41.

[0057] In one embodiment, reference is made to Figures 9 to 11As shown, on the side closer to the lifting assembly 3, the distance between two adjacent second rollers 43 is L1, and on the side farther from the lifting assembly 3, the distance between two adjacent second rollers 43 is L2, where L1 < L2. That is, on the side closer to the lifting assembly 3, the second rollers 43 are arranged relatively more densely. When the translation part 41 moves to the third working position, the translation part 41 is relatively close to the lifting assembly 3, and part of its area extends out of the bottom plate 2 and is suspended. Since the second rollers 43 on the side closer to the lifting assembly 3 are arranged relatively more densely, the second guide groove 411 of the translation part 41 can still have a sufficient number of second rollers 43, so that the second rollers 43 can still provide sufficient support for the translation part 41, enabling it to stably support the cage 5.

[0058] In one embodiment, to avoid interference between the first support part 31, the translation part 41 and the second support part 44 during the loading and unloading of the cage, when the first support part 31 moves to the second working position and the translation part 41 moves to the third working position, the area of ​​the translation part 41 extending out of the bottom plate 2 and the second support part 44 are located between the two first support parts 31.

[0059] In one embodiment, the translation component 4 further includes a translation transmission mechanism connected to the translation part 41. The translation transmission mechanism includes, but is not limited to, a chain transmission mechanism, a belt transmission mechanism, a gear transmission mechanism, and a linkage transmission mechanism. Any transmission mechanism that can drive the translation part 41 to move can be used as a translation transmission mechanism.

[0060] Optionally, the translation transmission mechanism is a chain transmission mechanism, which includes a driving sprocket, a driven sprocket, and a chain that drives and cooperates with the driving sprocket and the driven sprocket. The driving sprocket is connected to a drive element (e.g., a motor), and a certain part of the chain is fixedly connected to the translation part 41, so that the chain part can drive the translation part 41 to move synchronously with it.

[0061] In one embodiment, reference is made to Figure 9 and Figure 10 As shown, the translation part 41 is provided with a plurality of second support parts 44 arranged at intervals along its moving direction. Furthermore, in a direction perpendicular to the plane where the second support parts 44 are located, the vertical projection of the second support parts 44 intersects the vertical projection of the two second guide rails 42 simultaneously, and the second support parts 44 span the two second guide rails 42, so that the second support parts 44 have sufficient area to support the cage 5.

[0062] In one embodiment, the translation component 4 further includes a lifting transmission mechanism for driving the second bearing part 44 to rise and fall. The lifting transmission mechanism includes, but is not limited to, screw transmission mechanism, chain transmission mechanism, gear and rack transmission mechanism, lead screw and nut transmission mechanism, hydraulic / pneumatic lifting transmission mechanism, scissor lifting transmission mechanism and electromagnetic lifting transmission mechanism. Any transmission mechanism that can change the height of the second bearing part 44 can be used as a lifting transmission mechanism.

[0063] In one embodiment, reference is made to Figures 1 to 3 As shown, this utility model also provides an unmanned transport vehicle, which includes a carriage 1 and the aforementioned cage loading and unloading device, with the cage loading and unloading device installed at the rear of the carriage 1.

[0064] In other embodiments, the cage loading and unloading device may also be installed on the side of the carriage 1.

[0065] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0066] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
