[0056] With the rapid development of the modern logistics industry towards automation and intelligence, smart warehousing applications are becoming increasingly widespread.

[0057] In a warehousing system, goods are often placed on shelves or stacked in designated areas, while cargo handling robots move on the ground to pick up, place, and transfer goods.

[0058] Since multiple cargo handling robots need to be installed on the ground, and these robots require a large amount of space to move goods, this application provides an OHT warehousing equipment and system. The following will describe in detail the solution provided by the embodiments of this application with reference to the accompanying drawings.

[0059] Figure 1 This is a schematic diagram of the overall structure of an OHT storage equipment provided in one embodiment of this application; Figure 2 yes Figure 1 A schematic diagram of part of the structure of the OHT storage equipment.

[0060] Reference Figure 1 and Figure 2As shown in the illustration, this application provides an OHT (Outdoor Storage and Transportation) warehousing equipment, including a mother car 100 and a daughter car 200. The warehousing system is equipped with a ceiling track, suspended in the air. The mother car 100 is mounted on the ceiling track, and the daughter car 200 is suspended from the mother car 100. The daughter car 200 includes a loading platform 210, a support assembly 220, and a telescopic conveyor assembly 230. The loading platform 210 is suspended from the mother car 100, and the mother car 100 drives the loading platform 210 to move along the ceiling track. The loading platform 210 is used to carry goods. Support component 220 is mounted on loading platform 210 and selectively abuts against fixed component 300 to stabilize loading platform 210, preventing it from swaying during loading and unloading and improving stability. Telescopic conveyor component 230 is mounted on loading platform 210 and selectively extends beyond it to transport goods, facilitating the movement of goods into or out of loading platform 210. Furthermore, since the overhead rail is suspended in the air, the mother car 100 drives the daughter car 200 to move along the overhead rail and transport goods, eliminating the need for ground space and allowing for greater storage capacity, thus increasing storage density.

[0061] For example, a ceiling track is installed between the storage area and the cargo transfer area in the warehousing system, and the mother car 100 drives the daughter car 200 to move along the ceiling track between the storage area and the cargo transfer area and transfer goods.

[0062] In some examples, the goods are bins. The following describes the solution of this application using the example of picking up and placing bins. The storage area is equipped with bin storage shelves, and the goods transfer area is equipped with flow rack shelves. The mother car 100 drives the daughter car 200 to approach the bin storage shelves or flow rack shelves and pick up and place bins.

[0063] For example, when the mother carriage 100 moves the loading platform 210 of the daughter carriage 200 to one side of the flow rack, the support component 220 extends from the loading platform 210 and supports the side of the flow rack, thereby fixing the loading platform 210 and keeping it relatively stable. Next, the telescopic conveyor component 230 extends from the loading platform 210 to receive the material box sliding off the flow rack. Then, the telescopic conveyor component 230, along with the material box, retracts into the loading platform 210, and the mother carriage 100 moves the loading platform 210 to one side of the material box storage rack in the storage area. Then, the support component 220 extends from the loading platform 210 and supports the material box storage rack, and the telescopic conveyor component 230 extends from the loading platform 210 and transfers the material box to the corresponding storage location.

[0064] When handling boxes placed on a standard bin storage rack, the mother trolley 100 moves the daughter trolley 200 to the designated storage location. The mother trolley 100 controls the daughter trolley 200 to move under the target box. Then, the support assembly 220 extends from the loading platform 210 and supports the uprights of the bin storage rack, ensuring the stability of the daughter trolley 200. Next, the telescopic conveyor assembly 230 extends from the loading platform 210 and extends under the box. Then, the mother trolley 100 raises the height of the daughter trolley 200. The telescopic conveyor assembly 230 of the daughter trolley 200 supports the box and lifts it off the storage location, above the shelf of the bin storage rack. The telescopic conveyor assembly 230 then transports the box onto the loading platform 210. Finally, the support assembly 220 and the telescopic conveyor assembly 230 retract into the loading platform 210, completing the box retrieval task.

[0065] When placing a bin into a conventional bin storage rack, the mother carriage 100 controls the daughter carriage 200 to move to the designated storage location. Then, the support assembly 220 extends from the loading platform 210 and abuts against the upright of the bin storage rack. At this time, the telescopic conveyor assembly 230 extends from the loading platform 200 and moves the bin to the storage location. Next, the mother carriage 100 controls the daughter carriage 200 to descend, causing the telescopic conveyor assembly 230 of the daughter carriage 200 to detach from the bin. Finally, both the support assembly 220 and the telescopic conveyor assembly 230 retract into the loading platform 210, completing the bin delivery task.

[0066] Figure 3 yes Figure 1 A schematic diagram of the mechanism of the sub-cart 200; Figure 4 yes Figure 3 A top view of the 200 sub-vehicle; Figure 5 This is a structural schematic diagram of the support component 220 in section 4.

[0067] Reference Figures 3 to 5 As shown, in some examples, the support assembly 220 includes a support member 221, a support arm 222, and a support drive assembly 223. The support member 221 is disposed at the end of the support arm 222, which is movably mounted on the loading platform 210 via a slide rail. The support drive assembly 223 is disposed on the loading platform 210 and connected to the support arm 222. The support drive assembly 223 can drive the support arm 222 to extend from the loading platform 210, allowing the support member 221 to abut against the fixed component 300. The fixed component 300 can be a column of a flow rack or a bin storage rack.

[0068] Alternatively, for example, the support member 221 can be a support block, support plate, roller, or other structural component, and the support arm 222 is a movable plate, the lower surface of which is mounted on the loading platform 210 via a slide rail. Additionally, ball bearings can be provided on one side of the support surface of the support block. The support drive assembly 223 can be a gear and rack assembly with a drive motor. The drive motor is fixedly mounted on the loading platform 210, the gear is mounted on the output end of the drive motor, and the rack is mounted on the movable plate. The drive motor drives the movable plate to move via the gear and rack, thereby outputting from or retracting from the loading platform 210. It is understood that the support drive assembly 223 can also be a lead screw drive assembly, a scissor-type telescopic drive assembly, a cylinder drive assembly, a hydraulic cylinder drive assembly, an electric cylinder drive assembly, or other linear drive assembly, as long as it can drive the movable plate to move.

[0069] In some examples, the support member 221 includes rollers disposed on the side of the support member 221 that contacts the fixed member 300. When the support drive assembly 223 drives the support arm to move, the rollers of the support member 221 abut against the surface of the fixed member 300, facilitating the movement of the support member 221 along the fixed member 300 and ensuring that the loading platform 210 can be lifted to support the material box when the support assembly 200 is extended.

[0070] In other examples, the support member may be configured as a support block with ball bearings positioned on the side of the support block that contacts the fixed member 300. When the support drive assembly 223 drives the support arm to move, the ball bearings of the support block abut against the surface of the fixed member 300, facilitating the movement of the support block along the fixed member 300 and ensuring that the loading platform 210 can be lifted to support the material box when the support assembly 200 is extended.

[0071] It should be noted that the fixed components can be the uprights or beams of the shelf; the uprights or beams of the protective netting; or the brackets set separately on the outside of the shelf to provide support.

[0072] Figure 6 yes Figure 5 A schematic diagram of the first state of the support component 220 during operation; Figure 7 yes Figure 5 A schematic diagram of the second state of the support component 220 during operation.

[0073] Reference Figure 6 and Figure 7As shown, during the loading and unloading process, the mother cart 100 moves to a designated position, then controls the daughter cart 200 to move to an appropriate height. Next, the support drive assembly 223 of the support assembly 220 controls the support arm 222 to move outward, causing its end support member 221 to abut against the fixed component 300 (e.g., a column), ensuring the stability of the loading platform 210 of the daughter cart 200. Finally, the telescopic conveyor assembly 230 of the daughter cart 200 loads and unloads goods. It can be understood that because the support assembly 220 abuts against the fixed component 300, the position of the loading platform 210 is fixed, facilitating the telescopic conveyor assembly 230 to move goods between the loading platform 210 and the shelf.

[0074] Reference Figure 3 and Figure 4 As shown, exemplarily, the telescopic conveyor assembly 230 includes a conveyor assembly 231 and a telescopic drive assembly 232. The conveyor assembly 231 is movably mounted on the loading platform 210 via a slide rail. The telescopic drive assembly 232 is fixedly mounted on the loading platform 210 and connected to the conveyor assembly 231. The telescopic drive assembly 232 can drive the conveyor assembly 231 to extend or retract from the loading platform 210. Specifically, during the picking and placing of goods, the telescopic drive assembly 232 drives the conveyor assembly 231 to extend from the loading platform 210 and dock with the flow rack or bin storage rack. After the picking and placing is completed, the telescopic drive assembly 232 drives the conveyor assembly 231 to retract into the loading platform 210. Exemplarily, the conveyor assembly 231 can be a belt conveyor assembly or a chain conveyor assembly, both of which are existing technologies and will not be described in detail here.

[0075] Understandably, when the material box partially slides onto the belt conveyor assembly under the action of the flow strip, the conveyor belt of the belt conveyor assembly can drive the entire material box to move onto the belt conveyor assembly. The telescopic drive assembly 232 can be a linear drive assembly such as a screw drive assembly, a gear and rack drive assembly, a cylinder, an electric cylinder, or a hydraulic cylinder, all of which are existing technologies and will not be described in detail here.

[0076] Continue to refer to Figure 3 and Figure 4 As shown, in some examples, the trolley 200 also includes a cargo protection assembly 240 disposed on the loading platform 210. This cargo protection assembly 240 includes two adjustable cargo pushing parts disposed opposite each other, which are used to hold cargo (e.g., a container) and prevent the cargo from falling off the loading platform 210 during movement. It is understood that the two adjustable cargo pushing parts are disposed opposite each other along a direction perpendicular to the conveying direction of the conveying assembly 231.

[0077] For example, each adjustable cargo moving unit includes a cargo guard plate 241 and a moving drive assembly 242. The cargo guard plate 241 is movably mounted on the loading platform 210 via a slide rail. The moving drive assembly 242 is fixedly mounted on the loading platform 210 and connected to the cargo guard plate 241, driving the cargo guard plate 241 to move. The two cargo guard plates 241, which are positioned opposite each other, move relative to each other or away from each other to adjust the distance between them, so that the distance between the two cargo guard plates 241 matches the size of the cargo, preventing the cargo from falling due to violent shaking during the movement of the trolley 200. The moving drive assembly 242 can be a linear drive assembly such as a lead screw and nut drive assembly, a gear and rack drive assembly, a cylinder, an electric cylinder, or a hydraulic cylinder, all of which are existing technologies and will not be described in detail here.

[0078] In other examples, two cargo guards 241 positioned opposite each other or moving in opposite directions can clamp cargo as the trolley 200 moves.

[0079] Such as 1 and Figure 2 As shown, in some examples, the sub-cart 200 also includes a positioning component 250, which is used to prevent the sub-cart 200 from swaying during the movement of the mother car 100. Specifically, the positioning component 250 includes a first positioning part 251 and a second positioning part 252. The first positioning part 251 is vertically disposed on the mother car 100, and the second positioning part 252 is vertically disposed on the loading platform 210. The first positioning part 251 can selectively engage with the second positioning part 252. When the first positioning part 251 and the second positioning part 252 are engaged, the first positioning part 251 can restrict the movement of the second positioning part 252, thereby restricting the swaying of the loading platform 210, ensuring the stability of the goods on the loading platform 210, and preventing them from falling off.

[0080] For example, in some examples, the first positioning part 251 includes a first fixing frame 2511 and a socket part 2512. The first fixing frame 2511 is vertically and fixedly mounted on the mother car 100, and the socket part 2512 is fixedly mounted on the lower end of the first fixing frame 2511. The second positioning part 252 includes a second fixing frame 2521 and a plug-in part 2522. The plug-in part 2522 can cooperate with the socket part 2512. The second fixing frame 2521 is vertically and fixedly disposed on the loading platform 210 and located directly below the first fixing frame 2511. The plug-in part 2522 is fixedly disposed at the top end of the second fixing frame 2521 and is coaxially disposed with the socket part 2512. When the lifting drive assembly 132 drives the loading platform 210 to rise to the moving height through the flexible lifting assembly 131, the insertion part 2522 can be inserted into the socket part 2512. The socket part 2512 can restrict the movement of the insertion part 2522, thereby restricting the swing of the loading platform 210.

[0081] To ensure effective positioning of the loading platform 210, each sub-cart 200 includes two positioning components 250. The two positioning components 250 are positioned opposite each other on either side of the loading platform 210. Furthermore, each first positioning part 251 may be provided with multiple insertion parts 2522, and the second positioning part 252 may be provided with a corresponding number of socket parts 2512, thereby enhancing the positioning of the loading platform 210 and ensuring its stability during movement.

[0082] like Figure 2 As shown, the mother car 100 includes a frame 110, a traveling assembly 120, and a hoisting and lifting assembly 130. The traveling assembly 120 is connected to the frame 110 and cooperates with a ceiling rail. The hoisting and lifting assembly 130 is mounted on the frame 110 and connected to a loading platform 210 for controlling the lifting and lowering of the loading platform 210. For example, the traveling assembly 120 includes a clamping assembly 121, traveling wheels 122, and a traveling drive assembly 123. The clamping assembly 121 is fixedly mounted on the frame 110 and cooperates with the ceiling rail. The traveling wheels 122 and the traveling drive assembly 123 are both mounted on the frame 110, with the traveling wheels 122 abutting against the ceiling rail. The traveling drive assembly 123 can drive the traveling wheels 122 to rotate, thereby moving the frame 110 along the ceiling rail. For example, the traveling drive assembly 123 can be a servo motor.

[0083] In some examples, multiple sets of clamping assemblies 121 are provided, and the multiple sets of clamping assemblies 121 are spaced apart on the frame 110 and respectively connected to the overhead rail to ensure a stable connection between the frame 110 and the overhead rail.

[0084] Additionally, for example, the hoisting lifting assembly 130 includes at least four flexible lifting components 131 and a lifting drive assembly 132. The at least four flexible lifting components 131 are evenly distributed on the frame 110 and connected to the trolley 200. The lifting drive assembly 132 is disposed on the frame 110 and is used to drive all the flexible lifting components 131 to control the lifting and lowering of the trolley 200. The multiple flexible lifting components 131 are evenly distributed on the frame 110 and operate simultaneously to control the lifting and lowering of the trolley 200, ensuring that the trolley 200 is subjected to balanced force and that lifting and lowering are smooth.

[0085] In some examples, the hoisting lifting assembly 130 includes one lifting drive assembly 132 and four flexible lifting assemblies 131, which are respectively located at the four corners of the frame 110. Opposite flexible lifting assemblies 131 are connected via synchronous shafts, and the lifting drive assembly 132 is fixedly mounted on the frame 110 and connected to two synchronous shafts. Additionally, the four flexible lifting assemblies 131 are respectively connected to the cargo platform 210 of the trolley 200 via lifting belts. That is, one lifting drive assembly 132 simultaneously drives all four flexible lifting assemblies 131 to move simultaneously, thereby controlling the lifting and lowering of the cargo platform 210. In other examples, two lifting drive assemblies 132 are provided on the frame 110, each lifting drive assembly 132 being connected to a drive shaft to control the movement of two flexible lifting assemblies 131 on one side of the frame 110.

[0086] In other examples, four lifting drive assemblies 132 may also be provided on the frame 110, with each of the four lifting drive assemblies 132 corresponding to a flexible lifting assembly 131, meaning that one lifting drive assembly 132 controls the movement of one flexible lifting assembly 131. It is understood that having one lifting drive assembly 132 control the movement of one flexible lifting assembly 131 allows for convenient adjustment of the tension of the flexible components of the flexible lifting assembly 131.

[0087] For example, the flexible lifting assembly 131 can be a belt lifting assembly, a steel belt lifting assembly, a chain lifting assembly, or a rope lifting assembly. In some examples, the lifting drive assembly 132 can be a servo motor. The flexible lifting assembly 131 includes a pulley and a lifting belt. The pulley is rotatably mounted on the frame 110, and the lifting belt is wound around the pulley.
