Description

Technical Field

[0001] This application relates to the field of loading and unloading equipment technology, and more specifically, to a loading and unloading equipment assembly. Background Technology

[0002] With the rapid development of global trade and the popularization of e-commerce, the demand for transportation and storage of goods has increased significantly. Traditional manual loading and unloading methods can no longer meet the needs of efficient, fast and safe logistics.

[0003] In related technologies, forklifts are used to unload goods from the automated storage and retrieval system (AS / RS) conveyor and transfer them to the cargo box of a truck. With the continuous development of intelligent warehousing, this loading method increases labor costs, has low work efficiency, and significantly impacts the efficiency of goods leaving the warehouse, resulting in excessively long outbound times. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, this application proposes a loading and unloading equipment assembly.

[0006] In view of the above, this application provides a loading and unloading equipment assembly, including: a conveying device, the conveying device including: a traveling mechanism, the traveling mechanism including a base plate, an active traveling structure and a driven traveling structure, both the active traveling structure and the driven traveling structure being disposed on a first side of the base plate, the active traveling structure including a traveling part, the driven traveling structure including a first roller and a transmission structure, the transmission structure including a first transmission part and a second transmission part, the first transmission part being connected to the first roller, and the maximum distance from a point on the transmission structure to the base plate being less than the maximum distance from a point on the first roller to the base plate; a conveying mechanism, disposed on a second side of the base plate, the conveying mechanism including a roller assembly and a transmission assembly, the roller assembly being connected to the second transmission part through the transmission assembly; and a driving mechanism, including a drive motor. The mechanism is used to drive the movement of the walking part of the active walking structure; when the drive mechanism stops working and the roller group rotates counterclockwise, the roller group drives the second transmission part to rotate clockwise through the transmission group; when the drive mechanism drives the active walking structure to move in the first direction, the active walking structure drives the driven walking structure to move in the first direction through the base plate, and the first roller drives the first transmission part to rotate clockwise; when the drive mechanism drives the active walking structure to move in the second direction, the active walking structure drives the driven walking structure to move in the second direction through the base plate, the first roller drives the second transmission part to rotate counterclockwise through the first transmission part, and the second transmission part drives the roller group to rotate clockwise through the transmission group.

[0007] This application provides a loading and unloading equipment assembly including a conveying device, which comprises a traveling mechanism, a conveying mechanism, and a drive mechanism. The loading and unloading equipment assembly can interface with the conveyor of an automated storage and retrieval system (AS / RS), and can directly transport goods from the conveyor to the cargo box of a truck or a flatbed truck.

[0008] The traveling mechanism includes a base plate, an active traveling structure, and a passive traveling structure. The base plate has a first side and a second side. The active traveling structure and the passive traveling structure are both located on the first side of the base plate, sharing the same side. The base plate serves as the mounting carrier for the active and passive traveling structures, ensuring their proper fit and dimensional alignment.

[0009] The active walking structure includes a walking unit, and the driven walking structure includes a first roller and a transmission structure. The maximum distance from a point on the transmission structure to the base plate is less than the maximum distance from a point on the first roller to the base plate. It can be understood that when the conveying equipment is placed on a loading surface (the loading surface is the ground, or the support plate of the adjusting equipment of the loading / unloading equipment group forms the loading surface), the first roller contacts the loading surface, and the transmission structure separates from the loading surface; the transmission structure will not contact the loading surface.

[0010] The transmission structure includes a first transmission part and a second transmission part. When the first transmission part rotates clockwise, it does not drive the second transmission part to rotate. When the second transmission part rotates counterclockwise, it does not drive the first transmission part to rotate. When the first transmission part rotates counterclockwise, it drives the second transmission part to rotate counterclockwise.

[0011] The conveying mechanism is located on the second side of the base plate, that is, the base plate is located between the active traveling structure and the conveying mechanism, and the base plate is also located between the driven traveling structure and the conveying mechanism. The conveying mechanism includes a roller assembly and a transmission assembly, and the roller assembly is connected to the second transmission unit through the transmission assembly.

[0012] The drive mechanism is used to drive the movement of the walking part of the active walking structure.

[0013] Taking the transfer of goods from the conveyor belt of an automated storage and retrieval system (AS / RS) to the cargo box of a truck as an example, the goods move from the conveyor belt onto the roller assembly of the conveying mechanism. At this time, the drive mechanism is not yet activated (i.e., the drive mechanism is stopped). Under the external force of the goods, the roller assembly rotates counterclockwise. The roller assembly drives the second transmission unit to rotate clockwise through the transmission assembly. The second transmission unit does not drive the first transmission unit to rotate, and the first transmission unit does not drive the first roller to roll. The first roller can remain in a fixed state, and the traveling mechanism does not move. The roller assembly can roll unimpeded counterclockwise, achieving unpowered rolling. At this time, the goods are pushed onto the roller assembly sequentially by the AS / RS conveyor belt until the conveying mechanism is full.

[0014] Then, the drive mechanism drives the active walking structure to move in the first direction. The active walking structure drives the driven walking structure to move in the first direction through the base plate. That is, the walking mechanism gradually moves towards the cargo box. The first roller of the driven walking structure can drive the first transmission part to rotate in the clockwise direction. The first transmission part will not drive the second transmission part to rotate. Therefore, the second transmission part will not drive the roller group to rotate through the transmission group. In other words, the roller group is in a stopped rolling state at this time.

[0015] Once the traveling mechanism is fully inside the cargo box, the drive mechanism drives the active traveling structure to move in the second direction. The active traveling structure, via the base plate, drives the driven traveling structure to move in the second direction, meaning the traveling mechanism moves out of the cargo box. The first roller rolls, driving the first transmission unit to rotate counter-clockwise. The first transmission unit drives the second transmission unit to rotate counter-clockwise, and the second transmission unit, via the transmission assembly, drives the roller assembly to rotate clockwise. As the roller assembly rotates clockwise, the goods on the roller assembly move towards the cargo box (i.e., the first direction). At this time, the direction of the goods' movement is opposite to the direction of the traveling mechanism's movement. As the traveling mechanism gradually exits the cargo box, the roller assembly also gradually transports the goods into the cargo box. Thus, when the traveling mechanism completely leaves the cargo box, the goods are also completely transported into the cargo box, completing the overall cargo transport.

[0016] Therefore, the loading and unloading equipment group of this application can effectively connect the conveyor and cargo box of the automated storage and retrieval system (AS / RS). Without using forklifts to transfer goods, the goods on the AS / RS conveyor can be automatically transferred to the cargo box by the loading and unloading equipment group. This means that manual loading is unnecessary, reducing labor input, improving loading efficiency, increasing outbound efficiency, and reducing outbound time, thus helping to lower loading and unloading costs. Furthermore, by rationally designing the cooperative structure of the conveyor's traveling mechanism, conveying mechanism, and drive mechanism, this application allows for the inbound and outbound of goods to be realized using only one drive mechanism, further reducing loading and unloading costs.

[0017] The loading and unloading equipment group described above according to this application may also have the following additional technical features:

[0018] In some technical solutions, the driven walking structure may optionally include: a first wheel frame connected to the base plate, with a portion of the first roller located within the first wheel frame; a first transmission wheel connected to the transmission assembly and the second transmission part; a first support bearing connected to the base plate, with both the first transmission wheel and the transmission structure located between the first wheel frame and the first support bearing; and a first rotating shaft passing through the first wheel frame, the first roller, the transmission structure, the first transmission wheel, and the first support bearing, with the first rotating shaft and the first transmission wheel rotatably connected; wherein the first roller can drive the first transmission part to rotate via the first rotating shaft.

[0019] In this technical solution, the composition of the driven walking structure is defined.

[0020] The driven walking structure includes a transmission structure, a first wheel frame, a first transmission wheel, a first support bearing, and a first rotating shaft. The first wheel frame is connected to the base plate, the first support bearing is connected to the base plate, and the transmission structure and the first transmission wheel are both located between the first wheel frame and the first support bearing.

[0021] Both the first roller and the first transmission part are fixedly connected to the first rotating shaft. The first transmission wheel is rotatably connected to the first rotating shaft, that is, the first transmission wheel can rotate relative to the first rotating shaft.

[0022] The drive mechanism is not yet operational. Under the external force of the cargo, the roller assembly rotates counterclockwise. The roller assembly drives the first transmission wheel to rotate via the transmission assembly, and the first transmission wheel drives the second transmission unit to rotate clockwise. Since the first transmission wheel is rotatably connected to the first shaft, the rotation of the first transmission wheel does not drive the first shaft to rotate, and consequently, it does not drive the first transmission unit to rotate. The first transmission unit does not drive the first roller to roll, and the first roller remains in a fixed state. The traveling mechanism does not move.

[0023] When the drive mechanism drives the active walking structure to move in the first direction, the rolling of the first roller of the driven walking structure can drive the first transmission part to rotate in the clockwise direction. The first transmission part will not drive the second transmission part to rotate, the second transmission part will not drive the first transmission wheel to rotate, and the first transmission wheel will not drive the roller group to rotate through the transmission group. In other words, the roller group is in a stopped rolling state at this time.

[0024] When the drive mechanism drives the active walking structure to move in the second direction, the first roller rolls to drive the first transmission part to rotate in the counterclockwise direction, the first transmission part drives the second transmission part to rotate in the counterclockwise direction, the second transmission part rotates to drive the first transmission wheel to rotate, and the first transmission wheel rotates to drive the roller group to rotate in the clockwise direction through the transmission group.

[0025] Understandably, the first wheel frame serves to support and fix the first roller, ensuring the trajectory of the first roller's movement.

[0026] It is understandable that the first support bearing is connected to the first rotating shaft to provide structural support for the rotation of the first rotating shaft.

[0027] In some technical solutions, the driven walking structure may optionally include: a transition plate, through which the second transmission part is connected to the first transmission wheel; a first sleeve, through which the first rotating shaft passes and the first sleeve, the first sleeve being located between the first transmission wheel and the first support bearing, the first rotating shaft being a stepped shaft, and the stepped surfaces of the first sleeve and the first rotating shaft engaging to position the first transmission wheel and the transmission structure along the axial direction of the first rotating shaft.

[0028] In this technical solution, the driven walking structure also includes a transition plate and a first sleeve.

[0029] The first sleeve is located between the first drive wheel and the first support bearing, and the transition plate is located on the side of the first drive wheel away from the first support bearing. The second drive unit is connected to the first drive wheel through the transition plate; that is, the transition plate connects to the second drive unit and is also connected to the first drive wheel. In other words, when the first drive wheel rotates, it drives the transition plate and the second drive unit to rotate.

[0030] The first rotating shaft is also connected to the transition plate and the first sleeve. The stepped surfaces of the first sleeve and the first rotating shaft mate to position the first transmission wheel and the transmission structure along the axial direction of the first rotating shaft. In other words, the first sleeve and the first rotating shaft mate to effectively position the first transmission wheel and the transmission structure along the axial direction of the first rotating shaft. This provides structural support to ensure the rotation path of the first transmission wheel and the transmission structure, and prevents the first transmission wheel and the transmission structure from shifting axially on the first rotating shaft.

[0031] In some technical solutions, the transmission structure may optionally include a ratchet, with the inner ring of the ratchet forming a first transmission part and the outer ring of the ratchet forming a second transmission part.

[0032] This technical solution specifically defines the composition of the transmission structure.

[0033] The transmission structure includes a ratchet, with the inner ring of the ratchet forming a first transmission part and the outer ring of the ratchet forming a second transmission part.

[0034] When the inner ring of the ratchet rotates clockwise, it does not cause the outer ring to rotate. When the outer ring of the ratchet rotates counterclockwise, it does not cause the inner ring to rotate. When the inner ring of the ratchet rotates counterclockwise, it causes the outer ring to rotate counterclockwise.

[0035] In some technical solutions, optionally, the walking unit includes a second roller, and the active walking structure further includes: a second wheel frame connected to the base plate, with a portion of the second roller located within the second wheel frame; a second transmission wheel, with the drive mechanism connected to the second transmission wheel; a second support bearing connected to the base plate, with the second transmission wheel located between the second wheel frame and the second support bearing; a second sleeve located between the second transmission wheel and the second support bearing; and a second rotating shaft passing through the second wheel frame, the second roller, the second transmission wheel, the second sleeve, and the second support bearing. The second rotating shaft is a stepped shaft, and the stepped surfaces of the second sleeve and the second rotating shaft mate to position the second transmission wheel along the axial direction of the second rotating shaft. The second transmission wheel drives the second roller to rotate via the second rotating shaft.

[0036] In this technical solution, the walking unit includes a second roller. The active walking structure also includes a second wheel frame, a second transmission wheel, a second support bearing, and a second rotating shaft. The second wheel frame is connected to the base plate, the second support bearing is connected to the base plate, and the second transmission wheel is located between the second wheel frame and the second support bearing.

[0037] The second drive wheel drives the second roller to rotate via the second rotating shaft. That is, the second drive wheel is fixedly connected to the second rotating shaft, and the second rotating shaft is also fixedly connected to the second roller.

[0038] The drive mechanism is connected to the second transmission wheel. The drive mechanism drives the second transmission wheel to rotate. The second transmission wheel drives the second roller to rotate through the second rotating shaft, so as to achieve the purpose of the drive mechanism driving the active walking structure to move in the first direction or driving the active walking structure to move in the second direction.

[0039] Understandably, the second wheel frame serves to support and fix the second roller, ensuring the movement trajectory of the second roller.

[0040] It is understandable that the second support bearing is connected to the second rotating shaft to provide structural support for the rotation of the second rotating shaft.

[0041] The active walking structure also includes a second sleeve, which is located between the second drive wheel and the second support bearing, and the second rotating shaft is also connected to the second sleeve.

[0042] The stepped surfaces of the second sleeve and the second shaft mate to position the second drive wheel along the axial direction of the second shaft. In other words, the second sleeve and the second shaft mate to effectively position the second drive wheel along the axial direction of the second shaft. This provides structural support to ensure the rotation path of the second drive wheel, prevents the second drive wheel from shifting axially along the first shaft, and ensures that the second drive wheel drives the second roller to rotate via the second shaft.

[0043] In some technical solutions, the traveling part may optionally include a rack, and the driving mechanism includes a first gear, with the rack and the first gear meshing, and the first gear rotating to drive the rack to move.

[0044] In this technical solution, the walking unit includes a rack, and the drive mechanism includes a first gear that meshes with the rack, which is connected to the base plate. The rotation of the first gear in the drive mechanism drives the rack to move along a first direction or a second direction, thereby driving the base plate to move along the first direction or the second direction.

[0045] In some technical solutions, optionally, there are multiple active walking structures and multiple driven walking structures; the multiple active walking structures are arranged at intervals along a first direction; along a third direction, each active walking structure is opposite to and arranged at intervals with one driven walking structure.

[0046] In this technical solution, the number and arrangement of the active walking structure and the passive walking structure are limited.

[0047] There are multiple active and multiple passive walking structures; that is, there are multiple active walking structures and multiple passive walking structures, and the number of active and passive walking structures is matched. Specifically, each active walking structure is paired with one passive walking structure.

[0048] Along the first direction, multiple active walking structures are arranged at intervals. Along the third direction, each active walking structure is opposite to and spaced apart from a passive walking structure.

[0049] This design increases the contact area and angle between the active and passive walking structures and the base plate, effectively supporting the base plate and conveying mechanism from multiple directions and angles. It provides structural support for the walking mechanism to effectively drive the conveying mechanism, ensuring the distance between different positions of the conveying mechanism and the load surface, preventing the conveying mechanism from tilting, and preventing goods on the roller assembly from sliding off the conveying mechanism.

[0050] In some technical solutions, optionally, the transmission assembly includes: a third support bearing connected to the base plate; a third transmission wheel, which is opposite to and connected to the first transmission wheel; a second gear connected to the roller assembly; a third gear meshing with the second gear, the second gear and the third gear rotating in opposite directions; and a gear shaft passing through the third support bearing, the third transmission wheel, and the third gear; the rotation of the first transmission wheel can drive the rotation of the third transmission wheel, and the third transmission wheel drives the roller assembly to rotate through the gear shaft, the third gear, and the second gear.

[0051] This technical solution defines the structure of the transmission assembly.

[0052] The transmission assembly includes a third support bearing, a third transmission wheel, a second gear, a third gear, and a gear shaft.

[0053] The third support bearing is connected to the base plate, which serves to support and fix the third support bearing.

[0054] Specifically, the third transmission wheel is located between the third support bearing and the third gear. The gear shaft passes through the third support bearing, the third transmission wheel, and the third gear.

[0055] The third drive wheel is positioned opposite the first drive wheel and is connected to the first drive wheel, for example, the third drive wheel and the first drive wheel are connected by a chain.

[0056] The third drive wheel is fixedly connected to the gear shaft, and the third gear is fixedly connected to the gear shaft. The second gear is connected to the roller assembly.

[0057] When the drive mechanism is not in operation, and the roller assembly rotates counterclockwise under the external force of the cargo, the roller assembly drives the second gear to rotate counterclockwise. The third gear, meshing with the second gear, rotates clockwise. The third gear drives the gear shaft and the third transmission wheel on the gear shaft to rotate clockwise. The third transmission wheel is connected to the first transmission wheel, and the first transmission wheel is connected to the second transmission part. Therefore, the first transmission wheel can drive the second transmission part to rotate clockwise, but the second transmission part will not drive the first transmission part to rotate. Since the first transmission part is connected to the first roller, the first transmission part will not drive the first roller to roll, and the first roller can remain in a fixed state, and the traveling mechanism will not move.

[0058] When the drive mechanism drives the active walking structure to move in the second direction, the first roller rolls to drive the first transmission part to rotate in the counterclockwise direction, the first transmission part drives the second transmission part to rotate in the counterclockwise direction, the second transmission part drives the first transmission wheel to rotate in the counterclockwise direction, the first transmission wheel drives the third transmission wheel and the third gear to rotate in the counterclockwise direction, the second gear rotates in the clockwise direction, and the second gear drives the roller assembly to rotate in the clockwise direction.

[0059] This setup provides reliable structural support for the efficient loading and unloading of goods.

[0060] In some technical solutions, the transmission assembly may optionally include: a third sleeve, which is located between the third transmission wheel and the third support bearing, and the gear shaft is also inserted through the third sleeve. The gear shaft is a stepped shaft, and the stepped surfaces of the third sleeve and the gear shaft are fitted together to position the third transmission wheel along the axial direction of the gear shaft.

[0061] In this technical solution, the structure of the transmission assembly is further defined so that the transmission assembly also includes a third sleeve.

[0062] The third sleeve is located between the third drive wheel and the third support bearing. The gear shaft also passes through the third sleeve. The stepped surfaces of the third sleeve and the gear shaft mate to position the third drive wheel axially along the gear shaft. In other words, the third sleeve and the gear shaft mate to effectively position the third drive wheel axially along the gear shaft, thus providing structural support to ensure the rotation path of the third drive wheel and preventing the third drive wheel from shifting axially along the gear shaft.

[0063] In some technical solutions, optionally, the roller assembly includes: a roller frame connected to a base plate; multiple rollers rotatably mounted on the roller frame, the multiple rollers being spaced apart along a first direction, a second gear connected to the outermost roller; and multiple roller sprockets, each roller being connected to a roller sprocket, the multiple roller sprockets being connected sequentially.

[0064] In this technical solution, the roller assembly includes a roller frame, multiple rollers, and multiple roller sprockets.

[0065] The roller frame is connected to the base plate; specifically, the roller frame is connected to the second side of the base plate.

[0066] Multiple rollers are rotatably mounted on a roller frame, which serves to install and fix the multiple rollers to ensure the distance between the rollers and the base plate. Any one of the multiple rollers can rotate relative to the roller frame.

[0067] Multiple rollers are arranged at intervals along a first direction. Each roller is connected to a roller sprocket. Multiple roller sprockets are connected together. A second gear is connected to the outermost roller. The rotation of the second gear can drive the outermost roller to rotate. Multiple rollers rotate synchronously and in the same direction under the action of multiple roller sprockets to achieve the purpose of transporting goods.

[0068] In some technical solutions, the conveying mechanism may optionally include: a stop plate, which is movably connected to the side of the roller assembly away from the transmission assembly, and the stop plate is movable relative to the roller assembly to switch between a first position and a second position; when the stop plate is in the first position, the stop plate is used to block the goods on the roller assembly; when the stop plate is in the second position, the stop plate releases the obstruction of the goods.

[0069] In this technical solution, the composition of the conveying mechanism is further defined.

[0070] The conveying mechanism also includes a stop plate, which is movably connected to the roller assembly and is located on the side of the roller assembly away from the transmission assembly.

[0071] The stop plate can move relative to the roller assembly to switch between a first position and a second position.

[0072] To prevent goods from sliding off the conveyor mechanism, a stop plate is installed on the side of the roller assembly away from the drive assembly. When the conveyor mechanism is receiving goods, the stop plate remains vertical (i.e., the stop plate is in the first position) to block the goods on the roller assembly and prevent them from sliding off the conveyor mechanism via the side of the roller assembly away from the drive assembly. This can meet the usage requirements of the conveyor mechanism being fully loaded with goods.

[0073] When shipment is required, adjust the stop plate to a horizontal position (i.e., the stop plate is in the second position) so that the goods can be transferred to the cargo box via the side of the roller assembly away from the drive assembly.

[0074] This setup improves the reliability of loading and unloading equipment during cargo loading and unloading, eliminates the need for manual labor to monitor cargo arrival at the equipment, further reduces the need for manual labor, and helps reduce the cost of loading and unloading cargo.

[0075] In some technical solutions, the stop plate is optionally rotatably connected to the roller assembly; when the stop plate is in the first position, at least a portion of the stop plate protrudes from the roller assembly along the direction from the bottom plate to the conveying mechanism.

[0076] In this technical solution, the cooperation structure between the stop plate and the roller assembly is further defined.

[0077] The stop plate is rotatably connected to the roller assembly. When the stop plate is in the first position, at least a portion of the stop plate protrudes from the roller assembly along the direction from the base plate to the conveying mechanism. That is, when the stop plate is in the first position, the stop plate is placed vertically, and the stop plate can block the goods on the roller assembly, preventing the goods from sliding out of the conveying mechanism via the side of the roller assembly away from the drive assembly.

[0078] In some technical solutions, the loading and unloading equipment group may optionally include: adjusting equipment, the adjusting equipment including a support plate, the conveying equipment located on one side of the support plate, the first roller abutting against the support plate, and the transmission structure arranged at intervals from the support plate.

[0079] In this technical solution, the structure of the loading and unloading equipment group is further defined so that the loading and unloading equipment group also includes an adjustment device, which includes a support plate, and the conveying equipment is located on one side of the support plate. That is, the adjustment device has the function of supporting and fixing the conveying equipment, and can raise the height of the conveying equipment so that the conveying mechanism of the conveying equipment can match the position of the cargo box, and the goods can be effectively transported into the cargo box by the conveying mechanism.

[0080] Understandably, along the height direction of the loading and unloading equipment group, the conveying equipment is located above the adjusting equipment, the first roller of the traveling mechanism abuts against the support plate, and the transmission structure is spaced apart from the support plate. The first roller can move on the support plate. There is a gap between the transmission structure and the support plate, and the transmission structure does not affect the movement of the traveling mechanism.

[0081] In some technical solutions, the adjusting device may optionally include: an adjusting structure located on the side of the support plate away from the conveying equipment; and multiple legs connected to the adjusting structure, which is used to drive the support plate to rotate.

[0082] In this technical solution, the structure of the adjustment device is further defined, such that the adjustment device includes an adjustment structure and multiple support legs.

[0083] The adjustment structure is located on the side of the support plate away from the conveying equipment. Multiple legs are connected to the adjustment structure. That is, multiple legs are connected to the support plate through the adjustment structure. The multiple legs have the function of supporting and fixing the support plate, which can raise the height of the support plate, and thus raise the height of the conveying equipment.

[0084] The adjustment structure can drive the support plate to rotate, thereby adjusting the position of the conveying equipment located above the support plate, so that the conveying equipment can match the position of the cargo box, and the goods can be effectively transported into the cargo box by the conveying mechanism.

[0085] Specifically, in order to ensure that the traveling mechanism does not collide with the cargo box during its forward movement, the position of the support plate is adjusted by adjusting the structure, thereby adjusting the position of the conveying equipment. This allows the traveling mechanism of the conveying equipment to match the position of the cargo box, avoiding collisions between the traveling mechanism and the cargo box during its movement, and ensuring the effectiveness and reliability of the conveying equipment in transporting goods.

[0086] In some technical solutions, optionally, the adjustment structure includes: multiple turntables, each turntable having a first end face connected to a support plate; a lead screw slide, wherein at least a portion of the turntables have their second end faces connected to at least one support leg via the lead screw slide; when a portion of the turntables is connected to the lead screw slide, the second end faces of the other portion of the turntables are connected to at least one support leg; and a first motor for driving the lead screw slide to work, the work of which can drive the support plate to rotate via the turntables.

[0087] In this technical solution, the adjustment structure includes multiple turntables, a lead screw slide, and a first motor.

[0088] Any one of the multiple turntables has a first end face and a second end face. The first end face of the turntable is connected to a support plate. The second end faces of at least a portion of the multiple turntables are connected to at least one support leg via a lead screw slide.

[0089] Specifically, the multiple turntables are categorized into different types, including a first turntable and a second turntable.

[0090] The first end face of the first turntable is connected to the support plate, and the second end face of the first turntable is connected to at least one support leg through a lead screw slide.

[0091] The first end face of the second turntable is connected to the support plate, and the second end face of the second turntable is connected to at least one support leg through a lead screw slide.

[0092] Alternatively, the first end face of the second turntable is connected to the support plate, and the second end face of the second turntable is connected to at least one support leg.

[0093] The first motor is used to drive the lead screw slide, which can drive the support plate to rotate via the turntable, so as to adjust the position of the conveying equipment located on the support plate, and make the traveling mechanism match the position of the cargo box.

[0094] It is understandable that when both the first turntable and the second turntable are connected to at least one support leg via a lead screw slide, there are multiple lead screw slides, including a first lead screw slide and a second lead screw slide. The first turntable is connected to at least one support leg via the first lead screw slide, and the second turntable is connected to at least one support leg via the second lead screw slide.

[0095] In some technical solutions, optionally, the lead screw slide includes: a lead screw connected to a first motor; and a slider screwed to the lead screw, the slider being connected to a turntable.

[0096] In this technical solution, the structure of the lead screw slide is further defined.

[0097] A lead screw slide consists of a lead screw and a slider. The slider is screwed to the lead screw. The slider is connected to a turntable.

[0098] The lead screw is connected to the first motor. The operation of the first motor can drive the lead screw to rotate, the rotation of the lead screw can drive the slider to move, and the movement of the slider can drive the turntable to work, so as to adjust the position of the support plate.

[0099] In some technical solutions, the loading and unloading equipment group may optionally include: a sensor located on the conveying equipment, the detection data of which is used to supply the control and adjustment structure for operation.

[0100] In this technical solution, the structure of the loading and unloading equipment group is further defined.

[0101] The loading and unloading equipment group also includes sensors, which are located on the conveying equipment. The conveying equipment serves as the mounting carrier for the sensors and has the function of installing and fixing them.

[0102] The sensor's detection data is used to confirm the positional relationship between the traveling mechanism and the cargo box, so as to adjust the working state of the adjustment structure, thereby adjusting the position of the support plate and the position of the conveying equipment and the cargo box.

[0103] In some technical solutions, the adjustment device may optionally include: multiple lifting units, each lifting unit being connected to a support leg, the lifting unit being used to raise or lower the support leg.

[0104] In this technical solution, the structure of the adjustment equipment is further defined, including multiple lifting units, each connected to a support leg. The lifting units are used to raise and lower the support legs. By controlling the operation of the lifting units, the position and height of the support plate are adjusted, thereby adjusting the position and height of the conveying equipment. This allows the conveying equipment to match the position of the cargo box, enabling the goods to be effectively transported into the cargo box via the conveying mechanism.

[0105] Specifically, in order to ensure that the traveling mechanism does not collide with the cargo box during its forward movement, multiple lifting parts are used to adjust the position of the support plate, thereby adjusting the position of the conveying equipment. This allows the traveling mechanism of the conveying equipment to match the position of the cargo box, avoiding collisions between the traveling mechanism and the cargo box during its movement, and ensuring the effectiveness and reliability of the conveying equipment in transporting goods.

[0106] In some technical solutions, optionally, the support plate is provided with a first slide rail and a second slide rail, the first roller is provided in the first slide rail, and the second roller of the active walking structure is provided in the second slide rail.

[0107] In this technical solution, the cooperation structure between the support plate and the traveling mechanism is further defined. The support plate is provided with a first slide rail and a second slide rail.

[0108] When the traveling part of the active traveling structure includes a second roller, the first roller is located on the first slide rail, and the second roller of the active traveling structure is located on the second slide rail. The first slide rail has the function of limiting the movement path of the first roller, and the second slide rail has the function of limiting the movement path of the second roller, thus ensuring the movement path of the traveling mechanism and thereby ensuring the positional relationship between the traveling mechanism and the cargo box.

[0109] In some technical solutions, the drive mechanism optionally includes a second motor, which is used to control the first transmission part to stop rotating.

[0110] In this technical solution, the structure of the drive mechanism is further defined.

[0111] The drive mechanism includes a second motor, which is used to control the first transmission part to stop rotating.

[0112] When goods move from the conveyor onto the roller assembly of the conveying mechanism, the drive mechanism is not yet activated. Under the external force of the goods, the roller assembly rotates counter-clockwise. The roller assembly drives the second transmission unit to rotate clockwise via the transmission assembly. The second transmission unit does not drive the first transmission unit to rotate and, through a second motor, controls the first transmission unit to stop rotating. The first transmission unit does not drive the first roller to roll, thus keeping the first roller in a fixed position, and the traveling mechanism remains stationary. The roller assembly can roll unimpeded counter-clockwise, achieving unpowered rolling.

[0113] Understandably, the second motor is a brake motor.

Detailed Implementation

[0135] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0136] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0137] The following reference Figures 1 to 17 This application describes loading and unloading equipment assemblies according to some embodiments.

[0138] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 9 , Figure 14 , Figure 15 , Figure 16 and Figure 17 As shown, a loading and unloading equipment group 1 according to some embodiments of this application includes a conveying device 12, which includes a traveling mechanism 100, a conveying mechanism 200 and a driving mechanism 300.

[0139] The walking mechanism 100 includes a base plate 110, an active walking structure 120, and a driven walking structure 130.

[0140] Both the active walking structure 120 and the passive walking structure 130 are located on the first side 112 of the base plate.

[0141] The active walking structure 120 includes a walking unit 121.

[0142] The driven walking structure 130 includes a first roller 131 and a transmission structure 132.

[0143] The transmission structure 132 includes a first transmission part 1322 and a second transmission part 1324.

[0144] The first transmission unit 1322 is connected to the first roller 131.

[0145] The maximum distance from a point on the transmission structure 132 to the base plate 110 is less than the maximum distance from a point on the first roller 131 to the base plate 110.

[0146] The conveying mechanism 200 is located on the second side 114 of the base plate.

[0147] The conveying mechanism 200 includes a roller assembly 210 and a transmission assembly 220.

[0148] The roller assembly 210 is connected to the second transmission unit 1324 via the transmission assembly 220.

[0149] The drive mechanism 300 is used to drive the movement of the walking part 121 of the active walking structure 120.

[0150] When the drive mechanism 300 stops working and the roller assembly 210 rotates counterclockwise, the roller assembly 210 drives the second transmission unit 1324 to rotate clockwise through the transmission assembly 220.

[0151] When the drive mechanism 300 drives the active walking structure 120 to move in the first direction, the active walking structure 120 drives the driven walking structure 130 to move in the first direction through the base plate 110, and the first roller 131 drives the first transmission part 1322 to rotate in the clockwise direction.

[0152] When the drive mechanism 300 drives the active walking structure 120 to move in the second direction, the active walking structure 120 drives the driven walking structure 130 to move in the second direction through the base plate 110. The first roller 131 drives the second transmission part 1324 to rotate in the counterclockwise direction through the first transmission part 1322. The second transmission part 1324 drives the roller group 210 to rotate in the clockwise direction through the transmission group 220.

[0153] This application provides a loading and unloading equipment assembly 1, which includes a conveying device 12. The conveying device 12 includes a traveling mechanism 100, a conveying mechanism 200, and a driving mechanism 300. The loading and unloading equipment assembly 1 can dock with the conveyor of an automated warehouse, and can directly transport goods 3 on the conveyor to the cargo box 2 of a truck or a flatbed truck.

[0154] The traveling mechanism 100 includes a base plate 110, an active traveling structure 120, and a driven traveling structure 130. The base plate 110 has a first side and a second side facing each other. The active traveling structure 120 is located on the first side 112 of the base plate, and the driven traveling structure 130 is also located on the first side 112 of the base plate, with both structures situated on the same side of the base plate 110. The base plate 110 serves as the mounting carrier for the active traveling structure 120 and the driven traveling structure 130, and it has the function of mounting and fixing the active traveling structure 120 and the driven traveling structure 130, ensuring the mating dimensions of the active traveling structure 120 and the driven traveling structure 130.

[0155] The active walking structure 120 includes a walking part 121, and the driven walking structure 130 includes a first roller 131 and a transmission structure 132. The maximum distance from a point on the transmission structure 132 to the base plate 110 is less than the maximum distance from a point on the first roller 131 to the base plate 110. It is understood that when the conveying device 12 is placed on a loading surface (the loading surface is the ground, or the support plate 500 of the adjusting device of the loading / unloading equipment group 1 forms the loading surface), the first roller 131 contacts the loading surface, and the transmission structure 132 separates from the loading surface and does not contact the loading surface.

[0156] The transmission structure 132 includes a first transmission part 1322 and a second transmission part 1324. When the first transmission part 1322 rotates clockwise, it does not drive the second transmission part 1324 to rotate. When the second transmission part 1324 rotates counterclockwise, it does not drive the first transmission part 1322 to rotate. When the first transmission part 1322 rotates counterclockwise, it drives the second transmission part 1324 to rotate counterclockwise.

[0157] The conveying mechanism 200 is located on the second side 114 of the base plate, that is, the base plate 110 is located between the active walking structure 120 and the conveying mechanism 200, and the base plate 110 is also located between the driven walking structure 130 and the conveying mechanism 200. The conveying mechanism 200 includes a roller assembly 210 and a transmission assembly 220, and the roller assembly 210 is connected to the second transmission unit 1324 through the transmission assembly 220.

[0158] The drive mechanism 300 is used to drive the movement of the walking part 121 of the active walking structure 120.

[0159] Taking the transfer of goods 3 from the conveyor of the automated storage and retrieval system (AS / RS) to the cargo box 2 of a truck as an example, goods 3 move from the conveyor to the roller assembly 210 of the conveying mechanism 200. At this time, the drive mechanism 300 has not started working (that is, the drive mechanism 300 is not working). The roller assembly 210 rotates counterclockwise under the action of the external force of the goods 3. The roller assembly 210 drives the second transmission part 1324 to rotate clockwise through the transmission part 220. The second transmission part 1324 does not drive the first transmission part 1322 to rotate, and the first transmission part 1322 does not drive the first roller 131 to roll. The first roller 131 can remain in a fixed state, and the traveling mechanism 100 does not move. The roller assembly 210 can roll counterclockwise without obstruction, achieving unpowered rolling. At this time, the goods 3 are pushed onto the roller assembly 210 by the AS / RS conveyor until the conveying mechanism 200 is full of goods 3.

[0160] Then, the drive mechanism 300 drives the active walking structure 120 to move in the first direction. The active walking structure 120 drives the driven walking structure 130 to move in the first direction through the base plate 110. That is, the walking mechanism 100 gradually moves towards the cargo box 2. The first roller 131 of the driven walking structure 130 can drive the first transmission part 1322 to rotate in the clockwise direction. The first transmission part 1322 will not drive the second transmission part 1324 to rotate. Therefore, the second transmission part 1324 will not drive the roller group 210 to rotate through the transmission group 220. In other words, the roller group 210 is in a stopped rolling state at this time.

[0161] After the walking mechanism 100 fully enters the cargo box 2, the drive mechanism 300 drives the active walking structure 120 to move in the second direction. The active walking structure 120 drives the driven walking structure 130 to move in the second direction via the base plate 110. That is, the walking mechanism 100 moves out of the cargo box 2. The first roller 131 rolls to drive the first transmission part 1322 to rotate counterclockwise. The first transmission part 1322 drives the second transmission part 1324 to rotate counterclockwise. The second transmission part 1324 drives the roller assembly 210 to rotate clockwise via the transmission group 220. When the roller assembly 210 rotates clockwise, the goods 3 located on the roller assembly 210 move towards the cargo box 2 (i.e., the first direction). At this time, the direction of movement of the goods 3 is opposite to the direction of movement of the walking mechanism 100. As the walking mechanism 100 gradually exits the cargo box 2, the roller assembly 210 also gradually transports the goods 3 into the cargo box 2. In this way, when the walking mechanism 100 completely leaves the cargo box 2, the cargo 3 is also completely sent into the cargo box 2, that is, the overall transportation of the cargo 3 is completed.

[0162] Therefore, the loading and unloading equipment group 1 of this application can effectively connect the conveyor and cargo box 2 of the automated storage and retrieval system (AS / RS). Without using forklifts to transfer goods 3, the goods 3 on the AS / RS conveyor can be automatically transferred to the cargo box 2 under the action of the loading and unloading equipment group 1. That is, there is no need for manual loading of goods 3, reducing labor input, improving the efficiency of loading goods 3, improving the efficiency of goods 3 leaving the warehouse, and reducing the time for goods 3 to leave the warehouse, which helps to reduce the cost of loading and unloading goods 3. In addition, by rationally setting the cooperative structure of the traveling mechanism 100, conveying mechanism 200, and drive mechanism 300 of the conveying equipment 12, this application can realize the entry and exit of goods 3 using only one drive mechanism 300, which can further reduce the cost of loading and unloading goods 3.

[0163] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 5 , Figure 10 and Figure 17As shown, the driven walking structure 130 includes a transmission structure 132, a first wheel frame 133, a first transmission wheel 134, a first support bearing 135, and a first rotating shaft 136.

[0164] The first wheel frame 133 is connected to the base plate 110.

[0165] A portion of the first roller 131 is located within the first wheel frame 133.

[0166] The first transmission wheel 134 connects the transmission assembly 220 and the second transmission unit 1324.

[0167] The first support bearing 135 is connected to the base plate 110.

[0168] The first transmission wheel 134 and the transmission structure 132 are both located between the first wheel frame 133 and the first support bearing 135.

[0169] The first rotating shaft 136 is connected to the first wheel frame 133, the first roller 131, the transmission structure 132, the first transmission wheel 134, and the first support bearing 135.

[0170] The first rotating shaft 136 and the first transmission wheel 134 are rotatably connected.

[0171] The first roller 131 can drive the first transmission unit 1322 to rotate via the first rotating shaft 136.

[0172] In this embodiment, the composition of the driven walking structure 130 is defined.

[0173] The driven walking structure 130 includes a transmission structure 132, a first wheel frame 133, a first transmission wheel 134, a first support bearing 135, and a first rotating shaft 136. The first wheel frame 133 is connected to the base plate 110, the first support bearing 135 is connected to the base plate 110, and the transmission structure 132 and the first transmission wheel 134 are both located between the first wheel frame 133 and the first support bearing 135.

[0174] Both the first roller 131 and the first transmission part 1322 are fixedly connected to the first rotating shaft 136. The first transmission wheel 134 is rotatably connected to the first rotating shaft 136, that is, the first transmission wheel 134 can rotate relative to the first rotating shaft 136.

[0175] The drive mechanism 300 is not in operation. Under the external force of the cargo 3, the roller assembly 210 rotates counterclockwise. The roller assembly 210 drives the first transmission wheel 134 to rotate via the transmission assembly 220. The first transmission wheel 134 drives the second transmission part 1324 to rotate clockwise. Since the first transmission wheel 134 is rotatably connected to the first rotating shaft 136, the rotation of the first transmission wheel 134 will not drive the first rotating shaft 136 to rotate, and therefore will not drive the first transmission part 1322 to rotate. The first transmission part 1322 will not drive the first roller 131 to roll, and the first roller 131 can remain in a fixed state. The traveling mechanism 100 will not move.

[0176] When the drive mechanism 300 drives the active walking structure 120 to move in the first direction, the first roller 131 of the driven walking structure 130 can drive the first transmission part 1322 to rotate in the clockwise direction. The first transmission part 1322 will not drive the second transmission part 1324 to rotate, the second transmission part 1324 will not drive the first transmission wheel 134 to rotate, and the first transmission wheel 134 will not drive the roller group 210 to rotate through the transmission group 220. That is to say, at this time the roller group 210 is in a stopped rolling state.

[0177] When the drive mechanism 300 drives the active walking structure 120 to move in the second direction, the first roller 131 rolls to drive the first transmission part 1322 to rotate in the counterclockwise direction, the first transmission part 1322 drives the second transmission part 1324 to rotate in the counterclockwise direction, the second transmission part 1324 rotates to drive the first transmission wheel 134 to rotate, and the first transmission wheel 134 rotates to drive the roller group 210 to rotate in the clockwise direction through the transmission group 220.

[0178] Understandably, the first wheel frame 133 has the function of supporting and fixing the first roller 131, and can ensure the movement trajectory of the first roller 131.

[0179] It is understandable that the first support bearing 135 is connected to the first rotating shaft 136 to provide structural support for the rotation of the first rotating shaft 136.

[0180] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 5 and Figure 10 As shown, the driven walking structure 130 also includes a transition plate 137 and a first sleeve 138.

[0181] The second transmission unit 1324 is connected to the first transmission wheel 134 via a transition plate 137.

[0182] The first rotating shaft 136 is also connected to the transition plate 137 and the first sleeve 138.

[0183] The first sleeve 138 is located between the first transmission wheel 134 and the first support bearing 135.

[0184] The first rotating shaft 136 is a stepped shaft.

[0185] The stepped surfaces of the first sleeve 138 and the first rotating shaft 136 mate to position the first transmission wheel 134 and the transmission structure 132 along the axial direction of the first rotating shaft 136.

[0186] In this embodiment, the driven walking structure 130 also includes a transition plate 137 and a first sleeve 138.

[0187] The first sleeve 138 is located between the first transmission wheel 134 and the first support bearing 135, and the transition plate 137 is located on the side of the first transmission wheel 134 opposite to the first support bearing 135. The second transmission part 1324 is connected to the first transmission wheel 134 through the transition plate 137. That is, the transition plate 137 is connected to the second transmission part 1324, and the transition plate 137 is also connected to the first transmission wheel 134. In other words, when the first transmission wheel 134 rotates, it will drive the transition plate 137 and the second transmission part 1324 to rotate.

[0188] The first rotating shaft 136 is also connected to the transition plate 137 and the first sleeve 138. The stepped surfaces of the first sleeve 138 and the first rotating shaft 136 mate to position the first transmission wheel 134 and the transmission structure 132 along the axial direction of the first rotating shaft 136. In other words, the first sleeve 138 and the first rotating shaft 136 mate to effectively position the first transmission wheel 134 and the transmission structure 132 along the axial direction of the first rotating shaft 136. This provides structural support to ensure the rotation path of the first transmission wheel 134 and the transmission structure 132, and prevents the first transmission wheel 134 and the transmission structure 132 from shifting axially on the first rotating shaft 136.

[0189] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 6 and Figure 17 As shown, the transmission structure 132 includes a ratchet 132a.

[0190] The inner ring of the ratchet 132a forms the first transmission part 1322.

[0191] The outer ring of the ratchet 132a forms the second transmission part 1324.

[0192] In this embodiment, the composition of the transmission structure 132 is specifically defined.

[0193] The transmission structure 132 includes a ratchet 132a, the inner ring of which forms a first transmission part 1322, and the outer ring of which forms a second transmission part 1324.

[0194] When the inner ring of ratchet 132a rotates clockwise, it does not drive the outer ring of ratchet 132a to rotate. When the outer ring of ratchet 132a rotates counterclockwise, it does not drive the inner ring of ratchet 132a to rotate. When the inner ring of ratchet 132a rotates counterclockwise, it drives the outer ring of ratchet 132a to rotate counterclockwise.

[0195] Understandable Figure 6 In order to be in Figure 5 The view of the ratchet from right to left is based on this.

[0196] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 5 As shown, the walking unit 121 includes a second roller 121a. The active walking structure 120 also includes a second wheel frame 122, a second transmission wheel 123, a second support bearing 124, and a second rotating shaft 126.

[0197] The second wheel frame 122 is connected to the base plate 110.

[0198] A portion of the second roller 121a is located within the second wheel frame 122.

[0199] The drive mechanism is connected to the second transmission wheel 123.

[0200] The second support bearing 124 is connected to the base plate 110.

[0201] The second drive wheel 123 is located between the second wheel frame 122 and the second support bearing 124.

[0202] The second sleeve 125 is located between the second drive wheel 123 and the second support bearing 124.

[0203] The second rotating shaft 126 is connected to the second wheel frame 122, the second roller 121a, the second transmission wheel 123, the second sleeve 125, and the second support bearing 124.

[0204] The second rotating shaft 126 is a stepped shaft.

[0205] The stepped surfaces of the second sleeve 125 and the second shaft 126 engage to position the second drive wheel 123 along the axial direction of the second shaft 126.

[0206] The second transmission wheel 123 drives the second roller 121a to rotate via the second rotating shaft 126.

[0207] In this embodiment, the walking unit 121 includes a second roller 121a. The active walking structure 120 also includes a second wheel frame 122, a second drive wheel 123, a second support bearing 124, and a second rotating shaft 126. The second wheel frame 122 is connected to the base plate 110, the second support bearing 124 is connected to the base plate 110, and the second drive wheel 123 is located between the second wheel frame 122 and the second support bearing 124.

[0208] The second drive wheel 123 drives the second roller 121a to rotate via the second rotating shaft 126. That is, the second drive wheel 123 is fixedly connected to the second rotating shaft 126, and the second rotating shaft 126 is also fixedly connected to the second roller 121a.

[0209] The drive mechanism is connected to the second transmission wheel 123. The drive mechanism drives the second transmission wheel 123 to rotate. The second transmission wheel 123 drives the second roller 121a to rotate through the second rotating shaft 126, so as to achieve the purpose of the drive mechanism driving the active walking structure 120 to move in the first direction or driving the active walking structure 120 to move in the second direction.

[0210] It is understandable that the second wheel frame 122 has the function of supporting and fixing the second roller 121a, and can ensure the movement trajectory of the second roller 121a.

[0211] It is understandable that the second support bearing 124 is connected to the second rotating shaft 126 to provide structural support for the rotation of the second rotating shaft 126.

[0212] The active walking structure 120 also includes a second sleeve 125, which is located between the second transmission wheel 123 and the second support bearing 124, and the second rotating shaft 126 is also connected to the second sleeve 125.

[0213] The stepped surfaces of the second sleeve 125 and the second rotating shaft 126 engage to position the second transmission wheel 123 along the axial direction of the second rotating shaft 126. In other words, the second sleeve 125 and the second rotating shaft 126 engage to effectively position the second transmission wheel 123 along the axial direction of the second rotating shaft 126. This provides structural support to ensure the rotation path of the second transmission wheel 123, prevents the second transmission wheel 123 from shifting axially along the first rotating shaft 136, and provides structural support to ensure that the second transmission wheel 123 drives the second roller 121a to rotate via the second rotating shaft 126.

[0214] For example, the drive mechanism is connected to the base plate 110 of the walking mechanism 100.

[0215] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 13As shown, the walking part 121 includes a rack 121b, and the drive mechanism 300 includes a first gear 400. The rack 121b and the first gear 400 mesh, and the first gear 400 rotates to drive the rack 121b to move.

[0216] In this embodiment, the walking part 121 includes a rack 121b, and the drive mechanism 300 includes a first gear 400, which meshes with the rack 121b. The rack 121b is connected to the base plate 110. The first gear 400 of the drive mechanism 300 rotates to drive the rack 121b to move in a first direction or a second direction, thereby driving the base plate 110 to move in the first direction or the second direction.

[0217] For example, the drive mechanism 300 is mounted on the adjustment device 14 of the loading and unloading equipment group 1.

[0218] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features: the number of active walking structures 120 and driven walking structures 130 are both multiple.

[0219] Multiple active walking structures 120 are arranged at intervals along the first direction.

[0220] Along the third direction, each active walking structure 120 is opposite to and spaced apart from a passive walking structure 130.

[0221] In this embodiment, the number and arrangement of the active walking structure 120 and the passive walking structure 130 are limited.

[0222] There are multiple active walking structures 120 and multiple driven walking structures 130. That is, there are multiple active walking structures 120 and multiple driven walking structures 130, and the number of active walking structures 120 and driven walking structures 130 is matched. Specifically, each active walking structure 120 is paired with one driven walking structure 130.

[0223] Along the first direction, multiple active walking structures 120 are arranged at intervals. Along the third direction, each active walking structure 120 is opposite to and arranged at intervals with a passive walking structure 130.

[0224] This configuration increases the contact area and contact angle between the active walking structure 120 and the driven walking structure 130 and the base plate 110, which can effectively support the base plate 110 and the conveying mechanism 200 from multiple directions and angles. It provides structural support for the walking mechanism 100 to effectively drive the conveying mechanism 200 to move, and can ensure the distance between the conveying mechanism 200 and the load surface at different positions, prevent the conveying mechanism 200 from tilting, and prevent the goods 3 on the roller group 210 from sliding off the conveying mechanism 200.

[0225] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 7 , Figure 8 , Figure 10 , Figure 15 and Figure 17 As shown, the transmission assembly 220 includes a third support bearing 221, a third transmission wheel 222, a second gear 223, a third gear 224, and a gear shaft 225.

[0226] The third support bearing 221 is connected to the base plate 110.

[0227] The third transmission wheel 222 is positioned opposite to and connected to the first transmission wheel 134.

[0228] The second gear 223 is connected to the roller assembly 210.

[0229] The third gear 224 meshes with the second gear 223.

[0230] The second gear 223 and the third gear 224 rotate in opposite directions.

[0231] The gear shaft 225 is connected to the third support bearing 221, the third transmission wheel 222 and the third gear 224.

[0232] The rotation of the first transmission wheel 134 can drive the rotation of the third transmission wheel 222.

[0233] The third transmission wheel 222 drives the roller assembly 210 to rotate via the gear shaft 225, the third gear 224, and the second gear 223.

[0234] In this embodiment, the structure of the transmission assembly 220 is defined.

[0235] The transmission assembly 220 includes a third support bearing 221, a third transmission wheel 222, a second gear 223, a third gear 224, and a gear shaft 225.

[0236] The third support bearing 221 is connected to the base plate 110, and the base plate 110 has the function of supporting and fixing the third support bearing 221.

[0237] Specifically, the third transmission wheel 222 is located between the third support bearing 221 and the third gear 224. The gear shaft 225 passes through the third support bearing 221, the third transmission wheel 222, and the third gear 224.

[0238] The third transmission wheel 222 is disposed opposite to the first transmission wheel 134, and the third transmission wheel 222 is connected to the first transmission wheel 134, for example, the third transmission wheel 222 and the first transmission wheel 134 are connected by a wheel chain.

[0239] The third transmission wheel 222 is fixedly connected to the gear shaft 225, and the third gear 224 is fixedly connected to the gear shaft 225. The second gear 223 is connected to the roller assembly 210.

[0240] When the drive mechanism 300 is not in operation, and the roller assembly 210 rotates counterclockwise under the external force of the cargo 3, the roller assembly 210 drives the second gear 223 to rotate counterclockwise. The third gear 224, which meshes with the second gear 223, rotates clockwise. The third gear 224 drives the gear shaft 225 and the third transmission wheel 222 on the gear shaft 225 to rotate clockwise. The third transmission wheel 222 is connected to the first transmission wheel 134, and the first transmission wheel 134 is connected to the second transmission part 1324. Therefore, the first transmission wheel 134 can drive the second transmission part 1324 to rotate clockwise, but the second transmission part 1324 will not drive the first transmission part 1322 to rotate. Since the first transmission part 1322 is connected to the first roller 131, the first transmission part 1322 will not drive the first roller 131 to roll, and the first roller 131 can remain in a fixed state. The traveling mechanism 100 will not move.

[0241] When the drive mechanism 300 drives the active walking structure 120 to move in the second direction, the first roller 131 rolls to drive the first transmission part 1322 to rotate in the counterclockwise direction. The first transmission part 1322 drives the second transmission part 1324 to rotate in the counterclockwise direction. The second transmission part 1324 drives the first transmission wheel 134 to rotate in the counterclockwise direction. The first transmission wheel 134 drives the third transmission wheel 222 and the third gear 224 to rotate in the counterclockwise direction. The second gear 223 rotates in the clockwise direction. The second gear 223 drives the roller assembly 210 to rotate in the clockwise direction.

[0242] This configuration provides reliable structural support for the effective loading and unloading of goods.

[0243] For example, the third drive wheel 222, the second gear 223 and the third gear 224 are located on the same side of the third support bearing 221.

[0244] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 8 and Figure 10 As shown, the transmission assembly 220 also includes a third sleeve 226.

[0245] The third sleeve 226 is located between the third transmission wheel 222 and the third support bearing 221.

[0246] The gear shaft 225 is also connected to the third sleeve 226.

[0247] Gear shaft 225 is a stepped shaft.

[0248] The stepped surfaces of the third sleeve 226 and the gear shaft 225 mate to position the third transmission wheel 222 along the axial direction of the gear shaft 225.

[0249] In this embodiment, the structure of the transmission assembly 220 is further defined such that the transmission assembly 220 also includes a third sleeve 226.

[0250] The third sleeve 226 is located between the third transmission wheel 222 and the third support bearing 221. The gear shaft 225 also passes through the third sleeve 226. The stepped surfaces of the third sleeve 226 and the gear shaft 225 mate to position the third transmission wheel 222 along the axial direction of the gear shaft 225. In other words, the third sleeve 226 and the gear shaft 225 mate to effectively position the third transmission wheel 222 along the axial direction of the gear shaft 225. This provides structural support to ensure the rotation path of the third transmission wheel 222 and prevents the third transmission wheel 222 from shifting axially on the gear shaft 225.

[0251] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 7 and Figure 15 As shown, the roller assembly 210 includes a roller frame 211, multiple rollers 212, and multiple roller sprockets 213.

[0252] The roller frame 211 is connected to the base plate 110.

[0253] Multiple rollers 212 are rotatably mounted on roller frame 211.

[0254] Multiple rollers 212 are arranged at intervals along the first direction.

[0255] The second gear 223 is connected to the outermost roller 212.

[0256] Each roller 212 is connected to a roller sprocket 213, and multiple roller sprockets 213 are connected in sequence.

[0257] In this embodiment, the roller assembly 210 includes a roller frame 211, a plurality of rollers 212 and a plurality of roller sprockets 213.

[0258] The roller frame is connected to the base plate 110, specifically, the roller frame is connected to the second side 114 of the base plate.

[0259] Multiple rollers 212 are rotatably mounted on roller frame 211. Roller frame 211 has the function of installing and fixing multiple rollers 212 to ensure the distance between rollers 212 and base plate 110. Any one of the multiple rollers 212 can rotate relative to roller frame 211.

[0260] Multiple rollers 212 are arranged at intervals along a first direction. Each roller 212 is connected to a roller sprocket 213. Multiple roller sprockets 213 are connected. A second gear 223 is connected to the outermost roller 212. The rotation of the second gear 223 can drive the outermost roller 212 to rotate. Multiple rollers 212 rotate synchronously and in the same direction under the action of multiple roller sprockets 213 to achieve the purpose of transporting goods 3.

[0261] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 1 , Figure 4 and Figure 7 As shown, the conveying mechanism 200 also includes a stop plate 230.

[0262] The stop plate 230 is movably connected to the side of the roller assembly 210 away from the transmission assembly 220.

[0263] The stop plate 230 is movable relative to the roller assembly 210 to switch between a first position and a second position.

[0264] When the stop plate 230 is in the first position, the stop plate 230 is used to block the goods 3 on the roller assembly 210.

[0265] When the stop plate 230 is in the second position, the stop plate 230 releases its obstruction of the cargo 3.

[0266] In this embodiment, the composition of the conveying mechanism 200 is further defined.

[0267] The conveying mechanism 200 also includes a stop plate 230, which is movably connected to the roller assembly 210 and is located on the side of the roller assembly 210 away from the transmission assembly 220.

[0268] The stop plate 230 is movable relative to the roller assembly 210 to switch between a first position and a second position.

[0269] To prevent the goods 3 from sliding out of the conveying mechanism 200, a stop plate 230 is provided on the side of the roller assembly 210 away from the transmission assembly 220. When the conveying mechanism 200 is receiving goods, the stop plate 230 remains vertical (that is, the stop plate 230 is in the first position) to block the goods 3 on the roller assembly 210, preventing the goods 3 from sliding out of the conveying mechanism 200 via the side of the roller assembly 210 away from the transmission assembly 220, thus meeting the usage requirements of the conveying mechanism 200 being fully loaded with goods 3.

[0270] When shipment is required, the stop plate 230 is adjusted to a horizontal position (that is, the stop plate 230 is in the second position) so that the goods 3 can be transferred to the cargo box 2 via the side of the roller assembly 210 away from the transmission assembly 220.

[0271] This setup improves the reliability of loading and unloading equipment group 1 when loading and unloading goods 3, avoids the need for personnel to stand at loading and unloading equipment group 1 to observe the arrival of goods 3, further reduces the requirements for manpower, reduces the input of manpower, and helps to reduce the cost of loading and unloading goods 3.

[0272] For example, the position of the stop plate 230 is manually controlled so that the stop plate 230 can be effectively switched between a first position and a second position.

[0273] For example, the controller of the loading and unloading equipment group 1 automatically controls the working position of the stop plate 230, so that the stop plate 230 can effectively switch between a first position and a second position.

[0274] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features: the stop plate 230 is rotatably connected to the roller group 210.

[0275] When the stop plate 230 is in the first position, at least a portion of the stop plate 230 protrudes from the roller assembly 210 along the direction from the base plate 110 to the conveying mechanism 200.

[0276] In this embodiment, the mating structure of the stop plate 230 and the roller assembly 210 is further defined.

[0277] The stop plate 230 is rotatably connected to the roller assembly 210. When the stop plate 230 is in the first position, at least a portion of the stop plate 230 protrudes from the roller assembly 210 along the direction from the base plate 110 to the conveying mechanism 200. That is, when the stop plate 230 is in the first position, the stop plate 230 is placed vertically, and the stop plate 230 can block the goods 3 on the roller assembly 210, preventing the goods 3 from sliding out of the conveying mechanism 200 via the side of the roller assembly 210 away from the transmission assembly 220.

[0278] In some other embodiments, the stop plate 230 is detachably connected to the roller assembly 210. That is, when receiving goods, the stop plate 230 is assembled onto the roller assembly 210. When shipping goods, the stop plate 230 is removed from the roller assembly 210.

[0279] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 1 , Figure 3 , Figure 11 and Figure 12 As shown, the loading and unloading equipment group 1 also includes an adjustment device 14. The adjustment device 14 includes a support plate 500.

[0280] The conveying device 12 is located on one side of the support plate 500.

[0281] The first roller 131 abuts against the support plate 500.

[0282] The transmission structure 132 and the support plate 500 are arranged at intervals.

[0283] In this embodiment, the structure of the loading and unloading equipment group 1 is further defined such that the loading and unloading equipment group 1 also includes an adjustment device 14, which includes a support plate 500, and the conveying device 12 is located on one side of the support plate 500. That is, the adjustment device 14 has the function of supporting and fixing the conveying device 12, and can raise the height of the conveying device 12 so that the conveying mechanism 200 of the conveying device 12 can match the position of the cargo box 2, and the goods 3 can be effectively conveyed into the cargo box 2 through the conveying mechanism 200.

[0284] Understandably, along the height direction of the loading and unloading equipment group 1, the conveying equipment 12 is located above the adjusting equipment 14, the first roller 131 of the traveling mechanism 100 abuts against the support plate 500, and the transmission structure 132 is spaced apart from the support plate 500. The first roller 131 can move on the support plate 500. There is a gap between the transmission structure 132 and the support plate 500, and the transmission structure 132 will not affect the movement of the traveling mechanism 100.

[0285] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 11 , Figure 12 and Figure 14 As shown, the adjustment device 14 includes an adjustment structure 600 and multiple support legs 700.

[0286] The adjustment structure 600 is located on the side of the support plate 500 away from the conveying equipment 12.

[0287] Multiple support legs 700 are connected to an adjustment structure 600, which is used to drive the support plate 500 to rotate.

[0288] In this embodiment, the structure of the adjustment device 14 is further defined such that the adjustment device 14 includes an adjustment structure 600 and a plurality of support legs 700.

[0289] The adjustment structure 600 is located on the side of the support plate 500 away from the conveying device 12. Multiple support legs 700 are connected to the adjustment structure 600. That is, multiple support legs 700 are connected to the support plate 500 through the adjustment structure 600. Multiple support legs 700 have the function of supporting and fixing the support plate 500, which can raise the height of the support plate 500, and thus raise the height of the conveying device 12.

[0290] The adjustment structure 600 can drive the support plate 500 to rotate, thereby adjusting the position of the conveying device 12 located above the support plate 500, so that the conveying device 12 can match the position of the cargo box 2, and the goods 3 can be effectively transported into the cargo box 2 through the conveying mechanism 200.

[0291] Specifically, in order to ensure that the traveling mechanism 100 does not collide with the cargo box 2 during its forward movement, the position of the support plate 500 is adjusted by adjusting the structure 600, thereby adjusting the position of the conveying equipment 12. This allows the traveling mechanism 100 of the conveying equipment 12 to match the position of the cargo box 2, preventing the traveling mechanism 100 from colliding with the cargo box 2 during its movement and ensuring the effectiveness and reliability of the conveying equipment 12 in transporting the goods 3.

[0292] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 11 , Figure 12 and Figure 14 As shown, the adjustment structure 600 includes multiple turntables 610, a lead screw slide 620, and a first motor 630.

[0293] The first end face 612 of each turntable is connected to the support plate 500.

[0294] At least a portion of the turntables 610 have their second end faces 614 connected to at least one support leg 700 via a lead screw slide 620.

[0295] When one part of the turntable 610 is connected to the lead screw slide 620, the second end face 614 of the other part of the turntable is connected to at least one support leg 700.

[0296] The first motor 630 is used to drive the lead screw slide 620 to work, and the work of the lead screw slide 620 can drive the support plate 500 to rotate through the turntable 610.

[0297] In this embodiment, the adjustment structure 600 includes a plurality of turntables 610, a lead screw slide 620, and a first motor 630.

[0298] Any one of the plurality of turntables 610 has a first end face and a second end face. The first end face 612 of the turntable is connected to the support plate 500. The second end faces 614 of at least a portion of the plurality of turntables 610 are connected to at least one support leg 700 via a lead screw slide 620.

[0299] Specifically, the multiple turntables 610 are classified into different types, such that the multiple turntables 610 include a first turntable and a second turntable.

[0300] The first end face 612 of the first turntable is connected to the support plate 500, and the second end face 614 of the first turntable is connected to at least one support leg 700 through the lead screw slide 620.

[0301] The first end face 612 of the second turntable is connected to the support plate 500, and the second end face 614 of the second turntable is connected to at least one support leg 700 through the lead screw slide 620.

[0302] Alternatively, the first end face 612 of the second turntable is connected to the support plate 500, and the second end face 614 of the second turntable is connected to at least one support leg 700.

[0303] The first motor 630 is used to drive the lead screw slide 620 to work. The work of the lead screw slide 620 can drive the support plate 500 to rotate through the turntable 610, so as to adjust the position of the conveying device 12 located on the support plate 500, so that the traveling mechanism 100 can match the position of the cargo box 2.

[0304] It is understandable that when both the first turntable and the second turntable are connected to at least one support leg 700 via a lead screw slide 620, there are multiple lead screw slides 620, including a first lead screw slide and a second lead screw slide. The first turntable is connected to at least one support leg 700 via the first lead screw slide, and the second turntable is connected to at least one support leg 700 via the second lead screw slide.

[0305] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 11 , Figure 12 and Figure 14 As shown, the lead screw slide 620 includes a lead screw 622 and a slider 624.

[0306] The lead screw 622 is connected to the first motor 630.

[0307] The slider 624 is screwed to the lead screw 622.

[0308] Slider 624 connects to turntable 610.

[0309] In this embodiment, the structure of the lead screw slide 620 is further defined.

[0310] The lead screw slide 620 includes a lead screw 622 and a slider 624. The slider 624 is screwed to the lead screw 622. The slider 624 is connected to the turntable 610.

[0311] The lead screw 622 is connected to the first motor 630. The operation of the first motor 630 can drive the lead screw 622 to rotate. The rotation of the lead screw 622 can drive the slider 624 to move. The movement of the slider 624 can drive the turntable 610 to work, so as to adjust the position of the support plate 500.

[0312] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 7 As shown, the loading and unloading equipment group 1 also includes a sensor 800.

[0313] Sensor 800 is located on conveying equipment 12.

[0314] The detection data from sensor 800 is used to power the control and regulation structure 600.

[0315] In this embodiment, the structure of the loading and unloading equipment group 1 is further defined.

[0316] The loading and unloading equipment group 1 also includes a sensor 800, which is installed on the conveying equipment 12. The conveying equipment 12 serves as the mounting carrier for the sensor 800 and has the function of installing and fixing the sensor 800.

[0317] The detection data from sensor 800 is used to confirm the positional relationship between the walking mechanism 100 and the cargo box 2, so as to adjust the working state of the adjustment structure 600, thereby adjusting the position of the support plate 500 and the position of the conveying equipment 12 and the cargo box 2.

[0318] For example, the loading and unloading equipment group 1 also includes a controller, and the sensor 800, the conveying device 12 and the adjusting device 14 are all connected to the controller. The controller is used to control the operation of the adjusting structure based on the detection data of the sensor 800.

[0319] For example, the controller, conveying device 12, and adjusting device 14 are independent structures.

[0320] For example, the controller is located in at least one of the conveying device 12 and the adjusting device 14.

[0321] For example, the controller is placed on the ground.

[0322] For example, the number of sensors 800 is one.

[0323] For example, there are multiple sensors 800. The multiple sensors 800 are all disposed on the traveling mechanism 100 of the conveying device 12, and the multiple sensors 800 are arranged at intervals.

[0324] For example, sensor 800 includes an infrared lidar.

[0325] For example, sensor 800 includes a position ranging sensor.

[0326] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 12As shown, the adjustment device 14 also includes multiple lifting units 900.

[0327] Each lifting unit 900 is connected to a support leg 700.

[0328] The lifting unit 900 is used to lift the outriggers 700.

[0329] In this embodiment, the structure of the adjustment device 14 is further defined, such that the adjustment device 14 also includes a plurality of lifting parts 900, each lifting part 900 being connected to a support leg 700, and the lifting part 900 being used to lift the support leg 700. By controlling the operation of the lifting parts 900, the position height of the support plate 500 is adjusted, thereby adjusting the position height of the conveying device 12, so that the position of the conveying device 12 can be matched with that of the cargo box 2, and the goods 3 can be effectively conveyed into the cargo box 2 via the conveying mechanism 200.

[0330] Specifically, in order to ensure that the traveling mechanism 100 does not collide with the cargo box 2 during its forward movement, the position of the support plate 500 is adjusted by multiple lifting parts 900, thereby adjusting the position of the conveying equipment 12. This allows the traveling mechanism 100 of the conveying equipment 12 to match the position of the cargo box 2, avoiding collisions between the traveling mechanism 100 and the cargo box 2 during its movement, and ensuring the effectiveness and reliability of the conveying equipment 12 in transporting goods 3.

[0331] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 3 As shown, the support plate 500 is provided with a first slide rail 510 and a second slide rail 520.

[0332] The first roller 131 is located on the first slide rail 510.

[0333] The second roller 121a of the active walking structure 120 is located on the second slide rail 520.

[0334] In this embodiment, the cooperation structure between the support plate 500 and the traveling mechanism 100 is further defined. The support plate 500 is provided with a first slide rail 510 and a second slide rail 520.

[0335] When the traveling part 121 of the active traveling structure 120 includes a second roller 121a, the first roller 131 is disposed on the first slide rail 510, and the second roller 121a of the active traveling structure 120 is disposed on the second slide rail 520. The first slide rail 510 has the function of limiting the movement path of the first roller 131, and the second slide rail 520 has the function of limiting the movement path of the second roller 121a, thus ensuring the movement path of the traveling mechanism 100 and thereby ensuring the positional relationship between the traveling mechanism 100 and the cargo box 2.

[0336] This embodiment provides a loading and unloading equipment group. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features, such as... Figure 4 As shown, the drive mechanism 300 includes a second motor 310. The second motor 310 is used to control the first transmission unit 1322 to stop rotating.

[0337] In this embodiment, the structure of the drive mechanism 300 is further defined.

[0338] The drive mechanism 300 includes a second motor 310, which is used to control the first transmission part 1322 to stop rotating.

[0339] When cargo 3 moves from the conveyor to the roller assembly 210 of the conveying mechanism 200, the drive mechanism 300 is not yet operational. Under the external force of cargo 3, the roller assembly 210 rotates counter-clockwise. The roller assembly 210 drives the second transmission unit 1324 to rotate clockwise via the transmission unit 220. The second transmission unit 1324 does not drive the first transmission unit 1322 to rotate and, through the second motor 310, controls the first transmission unit 1322 to stop rotating. The first transmission unit 1322 does not drive the first roller 131 to roll, thus keeping the first roller 131 in a fixed state. The traveling mechanism 100 does not move. The roller assembly 210 can roll unimpeded counter-clockwise, achieving unpowered rolling.

[0340] Understandably, the second motor 310 is a brake motor.

[0341] This application rationally sets the structure of the loading and unloading equipment group 1, and adopts a single drive (e.g., drive mechanism 300) to realize the loading and transfer of the load (i.e., cargo 3), which is simple to control.

[0342] The loading and unloading equipment group 1 of this application is connected to the conveyor of the automated warehouse, eliminating the need for manual loading of goods 3 and greatly improving the outbound efficiency.

[0343] For example, the loading and unloading equipment group 1 includes a conveying device 12 and an adjusting device 14, with the conveying device 12 located above the adjusting device 14.

[0344] The conveying equipment 12 includes a traveling mechanism 100, a conveying mechanism 200, and a driving mechanism 300.

[0345] The walking mechanism 100 includes a base plate 110, an active walking structure 120, and a driven walking structure 130.

[0346] The walking mechanism 100 includes an active walking structure 120, a base plate 110, and a driven walking structure 130.

[0347] like Figure 5As shown, the active walking structure 120 includes a second roller 121a, a second wheel frame 122, a second transmission wheel 123 (e.g., a sprocket), a second support bearing 124, a second sleeve 125, and a second rotating shaft 126. The second rotating shaft 126 is a stepped shaft, passing sequentially through the second wheel frame 122, the second roller 121a, the second transmission wheel 123, the second sleeve 125, and the second support bearing 124. The second sleeve 125 cooperates with the second rotating shaft 126 to position the second transmission wheel 123 along the axial direction of the second rotating shaft 126. When the second transmission wheel 123 rotates, it drives the second rotating shaft 126 to rotate, which in turn drives the second roller 121a to rotate, thus realizing the forward and backward movement of the walking mechanism 100.

[0348] like Figure 5 As shown, the driven walking structure 130 includes a first rotating shaft 136, a first roller 131, a first wheel frame 133, a first sleeve 138, a first support bearing 135, a first transmission wheel 134 (e.g., a sprocket), a transition plate 137, and a transmission structure 132 (e.g., a ratchet 132a). The first rotating shaft 136 passes sequentially through the first wheel frame 133, the first roller 131, the ratchet 132a, the transition plate 137, the first sleeve 138, and the first support bearing 135. The active walking structure 120 and the driven walking structure 130 are on the same horizontal plane. When the active walking structure 120 moves, it drives the driven walking structure 130 to move. The first roller 131 of the active walking structure 120 drives the first rotating shaft 136 to rotate. The first rotating shaft 136 is fixed to the inner ring of the ratchet 132a, thereby driving the inner ring of the ratchet 132a to rotate. When the inner ring of ratchet 132a rotates clockwise, it does not drive the outer ring of ratchet 132a to rotate. When the outer ring of ratchet 132a rotates counterclockwise, it does not drive the inner ring of ratchet 132a to rotate. When the inner ring of ratchet 132a rotates counterclockwise, it drives the outer ring of ratchet 132a to rotate together. The outer ring of ratchet 132a is connected to transition plate 137, which in turn is connected to the first drive wheel 134. Thus, when the first drive wheel 134 rotates, it drives the transition plate 137 and the outer ring of ratchet 132a to rotate together. Ratchet 132a and the first drive wheel 134 are positioned by a stepped shaft (i.e., the first rotating shaft 136) and a first sleeve 138. In addition, multiple active walking structures 120 and multiple driven walking structures 130 can be provided on the base plate 110 as needed.

[0349] like Figure 7 and Figure 15As shown, the conveying mechanism 200 includes a roller assembly 210, a stop plate 230, and a transmission assembly 220. The roller assembly 210 includes multiple rollers 212, a roller frame 211, and multiple roller sprockets 213. The transmission assembly 220 includes a second gear 223, a third gear 224, a gear shaft 225, a third transmission wheel 222, and a third support bearing 221. The roller frame 211 and the third support bearing 221 are both fixedly connected to the base plate 110. The gear shaft 225 passes through the third support bearing 221, the third sleeve 226, the roller frame, and the third gear 224. The gear shaft 225 is a stepped shaft, and the gear shaft 225 and the third sleeve 226 cooperate to limit the third transmission wheel 222 along the axial direction of the gear shaft 225. The third gear 224 is positioned by locking screws. The third transmission wheel 222 and the first transmission wheel 134 are located in the same vertical plane, ensuring that the first transmission wheel 134 can drive the third transmission wheel 222 to rotate. The third transmission wheel 222 then drives the gear shaft 225 to rotate, which in turn drives the third gear 224 and the second gear 223 to rotate. The second gear 223 is connected to the roller 212, driving the roller 212 to rotate, which in turn drives the roller sprocket 213 to rotate. The roller sprocket 213 connects each roller 212 via a chain, thus driving each roller 212 to rotate, achieving the transport of goods 3.

[0350] like Figure 11 , Figure 12 and Figure 14 As shown, the adjustment device 14 includes a support plate 500, multiple turntables 610, multiple support legs 700, and a lead screw slide 620. The first end face 612 of the turntables is connected to the support plate 500, the second end face 614 of a portion of the turntables is connected to the support legs 700, and the second end face 614 of another portion of the turntables is connected to the support legs 700 via the lead screw slide 620. All support legs 700 are fixed to the ground. When the first motor 630 drives the lead screw slide 620, it causes the support plate 500 to rotate left and right via the multiple turntables 610, thereby adjusting the position of the conveying device 12.

[0351] The loading and unloading equipment assembly 1 of this application can be connected to an external conveyor. When the cargo 3 moves from the external conveyor onto the roller 212 of the conveying mechanism 200, the roller 212 rotates counterclockwise under the action of the cargo 3. Since the roller 212 is connected to the second gear 223, the second gear 223 rotates counterclockwise, and the third gear 224 meshing with the second gear 223 rotates clockwise, thereby driving the gear shaft 225 and the third transmission wheel 222 on the gear shaft 225 to rotate clockwise. The third transmission wheel 222 is connected to the first transmission wheel 134, and the first transmission wheel 134 is fixedly connected to the outer ring of the ratchet 132a, thus driving the outer ring of the ratchet 132a to rotate clockwise. Since the inner ring of the ratchet 132a is fixedly connected to the first roller 131, and the second motor 310 is a brake motor, the second motor 310 can control the first transmission part 1322 to stop rotating. Therefore, under the action of the brake motor, the traveling mechanism 100 remains stationary. At this time, the roller 212 of the conveying mechanism 200 can roll counterclockwise without obstruction, achieving unpowered rolling. At this time, the goods 3 are pushed forward by the external conveyor until the conveying mechanism 200 is full of goods 3. In order to prevent the goods 3 from slipping out of the conveying mechanism 200, a stop plate 230 is set on the left side of the conveying mechanism 200. When the conveying mechanism 200 is feeding, the stop plate 230 remains vertical. When it is necessary to unload, the stop plate 230 is adjusted to a horizontal position. After the goods 3 are loaded, the entire goods 3 can be unloaded. At this time, the external cargo box 2 approaches the loading and unloading equipment group 1. To ensure that the traveling mechanism 100 does not collide with the cargo box 2 during its forward movement, sensors 800 (e.g., infrared lidar) are installed on the left and right sides of the front end of the traveling mechanism 100. When the detection values ​​of the two sets of sensors 800 are equal, it indicates that the traveling mechanism 100 is parallel to the cargo box 2. Only then can the traveling mechanism 100 be driven to move forward. Otherwise, the position can be adjusted by adjusting the lead screw slide 620 of the adjustment device 14 at the bottom to achieve a horizontal arrangement between the traveling mechanism 100 and the cargo box 2.

[0352] When the cargo box 2 and the traveling mechanism 100 are in a horizontal position, the stop plate 230 is manually adjusted to the second position. The drive mechanism 300 drives the second roller 121a of the active traveling structure 120 to rotate clockwise. Under the action of the chain, the traveling mechanism 100 begins to move to the left as a whole, and the second roller 121a of the driven traveling structure 130 also begins to rotate clockwise, thereby driving the inner ring of the ratchet 132a to rotate clockwise. At this time, the inner ring and the outer ring of the ratchet 132a are not locked, and the inner ring of the ratchet 132a will not drive the outer ring of the ratchet 132a to rotate, thereby driving the roller 212 of the conveying mechanism 200 to rotate. Since the drive mechanism 300 is fixed on the base plate 110, it can drive the conveying equipment 12 to move forward. The support plate 500 of the adjustment device 14 is provided with a first slide rail 510 and a second slide rail 520. The second roller 121a of the active walking structure 120 rolls on the second slide rail 520, and the first roller 131 of the driven walking structure 130 rolls on the first slide rail 510, which further constrains the movement trajectory of the walking mechanism 100 and ensures the stability of the movement.

[0353] Once the traveling mechanism 100 is fully inside the cargo box 2, the drive mechanism 300 drives the second roller 121a of the active traveling structure 120 to rotate counterclockwise. Under the action of the chain, the active traveling structure 120 begins to move to the right as a whole. The second roller 121a of the driven traveling structure 130 also begins to rotate counterclockwise, thus the traveling mechanism 100 begins to move to the right as a whole. The driven traveling structure 130 drives the inner ring of the ratchet 132a to rotate counterclockwise, and the inner ring of the ratchet 132a drives the outer ring of the ratchet 132a to rotate counterclockwise, which in turn drives the first transmission wheel 134 to rotate counterclockwise. The first transmission wheel 134 drives the third transmission wheel 222 and the third gear 224 to rotate counterclockwise, and the second gear 223 rotates clockwise, which in turn drives the roller 212 to rotate clockwise. At this time, the rotation direction of either the first roller 131a or the second roller 121a is opposite to the rotation direction of the roller 212. As the traveling mechanism 100 gradually exits the cargo box 2, the roller 212 also gradually transports the goods 3 into the cargo box 2. This can be achieved by adjusting the transmission ratio. When the traveling mechanism 100 completely leaves the cargo box 2, the goods 3 are also completely fed into the cargo box 2, thus completing the overall transport of the goods 3.

[0354] The loading and unloading equipment group 1 of this application can efficiently deliver the goods 3 into the cargo box 2 as a whole, which greatly improves the efficiency of goods 3 entering and leaving the warehouse.

[0355] This application uses only one prime mover (i.e., drive mechanism 300) to realize the entry and exit of goods 3, which greatly reduces transportation costs. It can also be connected with external conveying equipment 12 to integrate the entire automated warehouse into a whole, greatly reducing manual intervention.

[0356] In some other embodiments, the walking mechanism 100 can be a rack and pinion drive, that is, the drive mechanism 300 is positioned near the exit end, the rack 121b is fixed to the base plate 110, and the drive mechanism 300 is fixed to the adjustment device 14. When the first gear 400 of the drive mechanism 300 rotates, it can drive the rack 121b to move back and forth, thereby driving the base plate 110 to move back and forth, thus achieving the same effect as described above. Specifically, the drive mechanism 300 is mounted on the support plate 500 of the adjustment device 14.

[0357] For example, when the second transmission wheel 123 rotates, the second transmission wheel 123 drives the second rotating shaft 126 to rotate, which in turn drives the second roller 121a to rotate, thereby realizing the forward and backward movement of the walking mechanism 100.
