Description

Technical Field

[0001] The present invention belongs to the technical field of logistics three-dimensional warehousing equipment, and in particular relates to an intelligent commodity automobile three-dimensional warehouse. Background Art

[0002] Current logistics and storage equipment is diverse, with varying technical features. While urban parking garages don't fall under the category of logistics and storage equipment, with the substantial increase in finished vehicle logistics, most locations with large vehicle storage needs, including automakers, ro-ro terminals, and railway stations, are using urban parking garage technology, either directly or with minor modifications, to build them.

[0003] For example, in an existing flat-surface mobile parking garage, a reversing lift and transporter transfer the vehicle to a trolley. The trolley then moves the vehicle to a designated parking space, where the transporter then moves the vehicle to the parking space. To retrieve a vehicle, the trolley moves to the designated parking space, where the transporter transfers the vehicle to the trolley. The vehicle is then transported to the entry and exit hall via a reversing lift. The vehicle is retrieved with the front facing outward, allowing the owner to drive away directly. The transporter then crawls under the vehicle from the front or rear, gripping the tires with eight gripping arms to lift the vehicle off the ground. The vehicle is then moved in and out of the parking space by the transporter. This flat-surface mobile parking garage is suitable for urban parking garages, but its application as a commercial vehicle storage technology struggles to meet storage density, efficiency, and cost requirements. Currently, China is the world's largest automobile manufacturer and exporter, and commercial vehicle storage has become a prominent challenge and pain point in the industry. Research is urgently needed to develop a commercial vehicle storage system with high density, high efficiency, and low cost. Summary of the Invention

[0004] The present invention proposes an intelligent commercial vehicle stereoscopic warehouse, which is designed for the batch warehousing and outbound transportation of port roll-on / roll-off terminals and automobile main engine factories. Based on the organic combination of the recessed vertical and horizontal channels of the stereoscopic warehouse body, the lifting mechanism, the recessed interactive platform, and the AGV transporter, a large-scale storage and logistics device that can achieve high-density and high-efficiency storage and retrieval of commercial vehicles is constructed. The present invention breaks through the constraint that the traditional planar movement of automobiles can only be achieved by clamping the automobile tires. By lifting the longitudinal beams of the chassis of the commercial vehicle with a backpack-type AGV transporter, the original innovation of the planar movement of the commercial vehicle is achieved. The innovative design of the entire process is carried out around this original innovation, realizing a digital, green and efficient commercial vehicle logistics and warehousing solution that can meet the port's high requirements for efficiency and comply with fire protection design specifications, and can also meet the port's stringent requirements for cost.

[0005] The present invention is achieved by adopting the following technical solutions: A commercial vehicle stereoscopic warehouse is proposed, which consists of a stereoscopic warehouse body, a lifting mechanism, an interactive platform and an AGV transport vehicle. The main body of the three-dimensional warehouse is composed of at least one multi-layer car storage layer; each car storage layer is composed of a recessed longitudinal conveying channel and multiple recessed transverse storage channels; the platforms on both sides of the recessed structure of the transverse storage channel are car storage platforms; The lifting mechanism consists of a lift shaft and a car, which are arranged at both ends of the longitudinal conveying channel. The lift shaft is connected to each car storage layer in a layered structure; the bottom of the car is connected to the bottom of the longitudinal conveying channel of each car storage layer; The interactive platform is arranged on the ground on both sides of the lifting mechanism, and a recessed transverse channel is arranged on it. When the elevator car of the lifting mechanism descends to the ground, the bottom of the car docks with the bottom of the transverse channel arranged on the interactive platform. The lifting platform is arranged in the recessed transverse channel. The lifting height of the lifting platform is consistent with the height of the interactive platform, and the lowering depth of the lifting platform is consistent with the depth of the recessed transverse channel. The AGV transporter is deployed throughout the entire warehouse and moves in the horizontal channels of the interactive platform, the elevator car, and the longitudinal conveying channels and horizontal storage channels of the warehouse body.

[0006] Taking the warehousing operation of the stereoscopic warehouse as an example, the car storage layer is equipped with two AGV transporters, namely AGV transporters No. 1 and No. 2. After the driver or straddle carrier transfers the commodity car to the interactive platform on the side of the lifting mechanism, the driver or straddle carrier exits the interactive platform, and the lifting platform in the interactive platform is lowered to the bottom of the recessed horizontal channel and connected to the bottom of the lifting mechanism car. The No. 1 AGV transporter in the lifting mechanism car drives into the interactive platform. The No. 1 AGV transporter's top lifting beam rises and hits the two longitudinal bottom beams under the chassis of the commodity car until the four wheels of the commodity car leave the interactive platform. Then, the No. 1 AGV transporter carries the commodity car into the lifting mechanism car. After the lifting mechanism rises to the target layer, the No. 1 AGV transporter carries the commodity car from the lifting mechanism car longitudinally into the longitudinal conveying channel of the stereoscopic warehouse, and waits for the No. 2 AGV transporter in the horizontal storage channel near the lifting mechanism to move from the horizontal storage channel into the longitudinal conveying channel and then enter the lifting mechanism car; the No. 1 AGV transporter carrying the commodity car The transporter drives along the longitudinal conveyor channel to the intersection with the target transverse storage channel and pauses. AGV #1 rotates its steering and steer wheels 90 degrees and drives into the target parking space in the transverse storage channel. At the target parking space, the AGV's top lifting beam retracts until the four wheels of the merchandise vehicle land on the vehicle storage platform. It then drives into the longitudinal conveyor channel and along the longitudinal conveyor channel to the lifting mechanism, repeating the above process. During this time, the elevator of the interactive platform rises, and the driver or straddle carrier moves the merchandise vehicle onto the interactive platform. The driver or straddle carrier exits the interactive platform, and the interactive platform elevator descends. The lifting mechanism, carrying AGV #2, descends to the first floor, repeating the above process.

[0007] The outbound operation is the opposite of the inbound process and will not be described in detail.

[0008] Compared with the existing technology, it has the following advantages and positive effects: 1. The structure of the three-dimensional warehouse is simple: each unit and each car storage layer uses a recessed longitudinal conveying channel as the main channel, and multiple recessed transverse storage channels and car storage platforms as car storage space. Each transverse storage channel can store multiple cars; the bottom of the elevator car is connected to the bottom of the longitudinal conveying channel on each layer and the bottom of the recessed transverse channel of the interactive platform. The AGV transporter uses the depth of the recessed channel and the height of the commodity car chassis to allow the AGV transporter to sneak under the commodity car chassis from between the front and rear wheels on the side of the commodity car to carry out transportation operations. The AGV transporter can operate quickly, stably and seamlessly on both horizontal and vertical working surfaces, realizing a large-scale storage and logistics device for high-density and high-efficiency transportation of commodity cars.

[0009] 2. Efficient car storage and retrieval: Each car storage layer consists of a recessed longitudinal conveying channel and a transverse storage channel. Utilizing mature AGV omnidirectional motion technology and precise positioning technology, the omnidirectional AGV transporter only needs to make a 90-degree turn in the three-dimensional parking garage retrieval scenario. When the longitudinal conveying channel is the main channel, the AGV transporter can quickly drive along the main channel in the recessed longitudinal and transverse channels to the transverse storage channel where the target parking space is located, and then quickly locate the target parking space with a 90-degree turn, which can achieve efficient transportation within the layer; the lifting mechanism and the interactive platform are equipped with interconnected channels, thus forming an obstacle-free transportation channel for the AGV transporter in the longitudinal, transverse and vertical transportation within the warehouse, ensuring seamless transportation connection of cars in the vertical and horizontal directions and ensuring efficient transportation efficiency.

[0010] 3. Low cost: The simplified structural design brings significant low-cost effects such as eliminating the traditional lifting mechanism and rotating the turntable 90 degrees, and reducing land occupation.

[0011] 4. Compliance with fire protection design specifications: Based on the three-dimensional warehouse structure of the present invention, various solutions that comply with fire protection specifications can be designed according to the topography and area of the construction site, with each fire protection zone storing no more than 100 cars.

[0012] In some embodiments of the present invention, the depths of the recessed longitudinal conveying channel and the transverse storage channel are consistent; the width of the longitudinal conveying channel is greater than the width of the commercial vehicle, and the length is a multiple of the length of the commercial vehicle; the width of the transverse storage channel is less than the axle spacing of the commercial vehicle, and the length is a multiple of the width of the commercial vehicle; the sum of the widths of the transverse storage channel and the vehicle storage platforms on both sides is greater than the length of the commercial vehicle, so that the four wheels of a commercial vehicle can be parked exactly on the protruding vehicle storage platforms on both sides of the recessed transverse storage channel.

[0013] In some embodiments of the present invention, the length of the longitudinal conveying channel is adapted to the length of 17 commercial vehicles; the length of the transverse storage channel is adapted to the storage of 6 commercial vehicles, that is, the transverse storage channels on both sides of the longitudinal conveying channel are adapted to the storage of 3 commercial vehicles on each side.

[0014] In some embodiments of the present invention, the car is a longitudinal single-parking space three-door structure, the longitudinal door is connected to the longitudinal conveying channel, and the two transverse doors are connected to the interactive platforms on both sides of the ground; using this structure as the warehousing operation mode for the three-dimensional warehouse, an AGV transporter drives out of the left side of the car and enters the interactive platform on the left to transport the commodity car and then enters the car. The lifting mechanism carries the AGV transporting the commodity car to the target floor. After the AGV carrying the commodity car drives out of the car and enters the longitudinal conveying channel, another empty AGV transporter enters the car and follows the lifting mechanism to descend to the ground floor to connect with the exchange platform. The empty AGV transporter drives out of the right side of the car and enters the right The side interactive platform transports the commodity car..., so that during the time when the lifting mechanism rises and falls, and moves in and out, the left interactive platform is opened and closed once, and the right interactive platform is closed and opened once, and the operation is carried out in this cycle. After the AGV transporter carrying the commodity car enters the longitudinal conveying channel of the car storage layer, it moves to the target transverse storage channel according to the instructions. After the steering wheel and steering wheel rotate 90 degrees, the AGV transporter carries the commodity car to the target parking space. The AGV transporter retracts the lifting mechanism and drops the commodity car on the car storage platform, returns to the longitudinal conveying channel and drives towards the lifting mechanism..., and the cycle continues until the operation is completed.

[0015] In some embodiments of the present invention, the lifting mechanism is a longitudinal double-parking space three-door structure, the longitudinal door is connected to the longitudinal conveying channel, and the two transverse doors are respectively opened on the sides of the two parking spaces and on different sides, and are respectively connected to the exchange platforms on both sides of the ground. Correspondingly, the lifting mechanism car is designed as a double-parking space structure, and an interactive platform is configured on the left front and right rear of each side of the corresponding lifting mechanism shaft on the ground. When this structure is used as the outbound operation mode of the three-dimensional warehouse, 4 AGV transporters are configured on the operating car storage layer, No. 1, No. 2, No. 3, and No. 4 AGV transporters, No. 1 and No. 2 in a group, and No. 3 and No. 4 in a group, can transport two cars out of the warehouse at the same time. When the lifting mechanism reaches the car storage layer, No. 1 and No. 2 AGV transporters carry the commodity cars and enter the lifting mechanism car in turn. When the lifting mechanism descends to the ground level, No. 1 and No. 2 AGV transporters, one on the left front and one on the right rear, drive out of the lifting mechanism car at the same time, and drive out respectively. Enter the left interactive platform and the right interactive platform. When the AGV transporter carrying the commodity car has completed the commodity car exchange with the interactive platform, the No. 1 and No. 2 AGV transporters enter the elevator car from the left interactive platform and the right interactive platform respectively at the same time; after the elevator carries the No. 1 and No. 2 empty AGV transporters to the working car storage layer, the No. 2 and No. 1 empty AGV transporters successively exit the elevator car to carry the car again, and the No. 3 and No. 4 AGV transporters carry the commodity car into the elevator car, and so on. In this way, during the time it takes for the elevator to rise and fall, exit and enter, the left and right interactive platforms are opened and closed at the same time, and the operation is carried out in this cycle efficiently. In some embodiments of the present invention, the length of the interactive platform is greater than the length of the commercial vehicle, and the width is greater than the width of the commercial vehicle. A recessed transverse channel is provided in the middle position, and the recessed depth is consistent with the recessed depth of the longitudinal conveying channel and the transverse storage channel of the three-dimensional warehouse body; the length of the transverse channel is greater than the width of the commercial vehicle, and the width is less than the axle spacing of the commercial vehicle, and is consistent with the width of the transverse storage channel of the three-dimensional warehouse body; the transverse channel is connected to the side door of the lifting mechanism car, and a lifting platform is configured therein. When the lifting platform is raised, it is at the same level as the interactive platform, which is convenient for commercial vehicles to enter and exit the interactive platform; when the lifting platform is lowered to the bottom, it is at the same level as the side position of the bottom of the car when the lifting mechanism falls to a car storage layer, which is convenient for commercial vehicles to interact between the lifting mechanism and the interactive platform.

[0016] In some embodiments of the present invention, the length of the AGV transporter is smaller than the distance between the front and rear wheels of the commercial vehicle, or smaller than the width of the transverse storage channel; its width is smaller than the width of the longitudinal conveying channel, or is adapted to the width of the commercial vehicle; its height is smaller than the sum of the depth of the recessed channel and the height of the vehicle chassis, so that the AGV transporter can enter and exit from under the vehicle chassis between the front and rear wheels of the vehicle in the transverse channel of the exchange platform and the transverse storage channel of the stereoscopic warehouse body, changing the way in which the existing car transporter enters the vehicle chassis from the longitudinal direction of the vehicle, thereby making it more convenient to transport cars and saving the floor space occupied by car storage and transport operations, which is conducive to simplifying the structure and cost of the stereoscopic warehouse and realizing the intensive design of the stereoscopic warehouse.

[0017] In the embodiment of the present invention, the height of the AGV transport vehicle is no higher than the sum of the depth of the recessed longitudinal conveying channel and the transverse storage channel and the height of the vehicle chassis, so that the AGV transport vehicle can operate in the recessed longitudinal and transverse channels without obstacles.

[0018] In the embodiment of the present invention, the AGV transport vehicle has a rectangular parallelepiped body, and two steering wheels and two steering wheels are arranged on the chassis of the body; and lifting mechanisms are arranged on both sides of the length direction of the interior of the body.

[0019] In some embodiments of the present invention, the lifting mechanism of the AGV transporter adopts an electric push-pull rod lifting structure to lift the two longitudinal beams of the automobile chassis. The lifting height is enough to lift the four wheels of the car off the ground, enabling the AGV transporter to move in the recessed vertical and horizontal channels with the car on its back.

[0020] In some embodiments of the present invention, the lifting mechanism consists of vertical push-pull mechanisms arranged along the length of the vehicle body and a horizontal spacing adjustment mechanism connected horizontally between the vertical push-pull mechanisms on both sides of the vehicle body. This allows the AGV to adjust the spacing between the vertical push-pull mechanisms based on the width of the chassis longitudinal beams of different models of commercial vehicles, thereby adapting to the handling of multiple models of commercial vehicles.

[0021] In some embodiments of the present invention, at least two vertical push-pull mechanisms are arranged on each side of the vertical body chassis on both sides of the inner length direction of the AGV transporter body, and each vertical push-pull mechanism is movable in the width direction of the body; a lifting beam is fixedly arranged horizontally at the push-pull end of the vertical push-pull mechanism on each side; multiple vertical push-pull mechanisms on both sides are connected to a rigid connection structure; a horizontal spacing adjustment mechanism for changing the spacing between the lifting beams on both sides is arranged between the rigid connection structures on both sides of the body.

[0022] The AGV transporter in the above-mentioned embodiment of the present invention enters the bottom of the car from the side, between the front and rear wheels of the car, in the horizontal channel of the interactive platform and the horizontal storage channel of the stereoscopic garage. Compared with the front-entry or rear-entry method of the transporter in the existing stereoscopic garage, it eliminates the functional facilities of the lifting mechanism rotating 90 degrees, reduces the demand for transport operation space, and contributes to the compact design of the garage, thereby improving the storage density of the car. The structure of the lifting beam and the longitudinal beam of the car chassis is used to lift the car off the ground. Compared with the existing clamping and transporting method, the AGV transporter has a simpler structural design, is better for the wheels, and significantly improves the transport efficiency. And the adjustment of the horizontal spacing adjustment mechanism can make the AGV transporter adaptable to different models, thereby increasing the applicability of the AGV transporter.

[0023] The intelligent commercial vehicle warehouse described in this invention utilizes artificial intelligence, digital technology, induction technology, and PLC control technology to achieve its design. AGVs are positioned within the warehouse using technologies such as magnetic induction and laser ranging. The spacing between the AGV's two lifting beams is adjusted during batch operations. After the data of the commercial vehicles to be transported is input into a computer, a horizontal spacing adjustment mechanism automatically adjusts the distance between the two lifting beams to accommodate the width of the two longitudinal bottom beams under the chassis of the vehicles being transported.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or through an intermediary. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0031] like Figures 1 to 15 As shown, the commodity automobile stereoscopic warehouse in the embodiment of the present application is composed of a stereoscopic warehouse body 1, a lifting mechanism 2, an interactive platform 3 and an AGV transport vehicle 4.

[0032] Among them, the main body 1 of the three-dimensional warehouse is composed of multiple layers of automobile storage layers 11, and each layer of automobile storage layer 11 is composed of a recessed longitudinal conveying channel 12 and multiple recessed transverse storage channels 13 to form a recessed non-shaped longitudinal and transverse channel; the platforms on both sides of the transverse storage channel 13 are automobile storage platforms 14.

[0033] The lifting mechanism 2 consists of a lifting shaft 21 and a car 22, which are arranged at both ends of the longitudinal conveying channel 12. The lifting shaft 21 is docked with each layer of the car storage layer 11 in a layered structure, and the first layer of the lifting shaft 21 is simultaneously docked with the first layer of the car storage layer 11 and the recessed transverse channel 31 of the interactive platform 3; the bottom of the car 22 is docked with the bottom of the recessed structure of the longitudinal conveying channel 12 of the car storage layer 11, and when the car 22 descends to the ground level, it is simultaneously docked with the first layer of the car storage layer 11 and the recessed transverse channel 31 of the interactive platform 3.

[0034] The interactive platform 3 is arranged on the ground on both sides of the lifting mechanism 2, and a recessed transverse channel 31 is arranged on it; when the car 22 of the lifting mechanism 2 descends to the ground, the bottom of the car 22 docks with the bottom of the recessed transverse channel 31 of the interactive platform 3.

[0035] The AGV transporter 4 is arranged in the entire three-dimensional warehouse and moves in the longitudinal conveying channel 12 and the transverse storage channel 13 of the interactive platform 3, the lifting mechanism 2, the main body 1 of the three-dimensional warehouse. The AGV transporter 4 is a rectangular vehicle body 41, and two steering wheels and two steering wheels are arranged crosswise on the vehicle chassis. Lifting mechanisms 42 are arranged on both sides of the length direction of the vehicle body 41. The AGV transporter 4 enters the bottom of the vehicle chassis between the front and rear wheels on the side of the vehicle. The lifting mechanism 42 lifts two longitudinal beams from under the vehicle chassis to lift the vehicle off the ground. The AGV transporter 3 carries the vehicle and runs in the transverse storage channel 13, the longitudinal conveying channel 12, the car 22 and the recessed transverse channel 31 structure of the interactive platform 3.

[0036] For example, the three-dimensional warehouse 1 has eight units and six floors of car storage 11. Each storage unit consists of a longitudinal conveying channel 12 and seventeen rows of transverse storage channels 13, with each row storing six cars. Each unit has 102 parking spaces per floor, two of which are reserved for maintenance access at each end of the unit. Each floor is designed for 100 parking spaces, meeting fire safety design regulations. A six-story unit can store 600 cars, and eight units can store 4,800 cars.

[0037] A lifting mechanism 2 is arranged at each end of the longitudinal conveying channel 12 of each unit, wherein the lifting mechanism 2 at the entrance end of the stereoscopic warehouse 1 is designed as a longitudinal single / double parking space three-car lifting mechanism 2, the longitudinal entry and exit end of the car 22 is connected to the longitudinal conveying channel 12 of the stereoscopic warehouse 1, and the entrances and exits on both sides of the car 22 are respectively connected to the left and right sides or the left front and right rear interactive platforms 3 on the ground; the lifting mechanism 2 at the exit end of the stereoscopic warehouse 1 is designed as a longitudinal double parking space three-car lifting mechanism 2, the longitudinal entry and exit end of the car 22 is connected to the longitudinal conveying channel 12 of the stereoscopic warehouse 1, and the left front and right rear entrances and exits on both sides of the car 22 are respectively connected to the left front interactive platform 3 and the right rear interactive platform 3 on the ground.

[0038] Each unit of the three-dimensional warehouse 1 is laid out as a crisscross pattern of recessed, non-vertical vertical and horizontal channels and vehicle storage spaces. The length of the longitudinal conveying channel 12 is a multiple of the length of the commercial vehicle, and its width is greater than the width of the commercial vehicle. The sum of the depth of the recessed structure and the height of the commercial vehicle's chassis is greater than the height of the AGV transporter 4. Transverse storage channels 13 are arranged on both sides of the longitudinal conveying channel 12. The length of the transverse storage channel 13 is a multiple of the width of the commercial vehicle, and its width is less than the distance between the commercial vehicle's axles. The recessed structures of the longitudinal conveying channel 12 and the transverse storage channel 13 are perpendicular to each other and intertwined, forming an operating path for the AGV transporter 4. The width of the transverse storage channel 13 is greater than the length of the AGV transporter 4 and less than the distance between the commercial vehicle's axles. The sum of the width of the vehicle storage platforms 14 on either side of the transverse storage channel 13 and the width of the transverse storage channel 13 is greater than the length of the vehicle. This allows the front and rear wheels of a vehicle to fit neatly across the vehicle storage platforms 14 on either side of the transverse storage channel 13, allowing the lifting mechanism 42 of the AGV transporter 4 to be positioned between the front and rear wheels, ensuring that the AGV transporter 4 can safely carry the vehicle.

[0039] The lifting shaft 21 of the lifting mechanism 2 is on the vertical center line at both ends of the three-dimensional warehouse 1, and is connected to the longitudinal conveying channel 12 of each car storage layer 11 of the three-dimensional warehouse 1. The length of the car 22 is a multiple of the length of the commercial vehicle, the width is greater than the width of the commercial vehicle, and the height is greater than the sum of the heights of the commercial vehicle and the AGV transport vehicle 4 after lifting; the car 22 and the lifting shaft 21 are open on both sides and the inner end, which is convenient for the AGV transport vehicle 4 to carry the commercial vehicle in and out of the lifting mechanism 2.

[0040] The interactive platforms 3 are arranged on the ground on both sides of the lifting shaft 21 of the lifting mechanism 2, and their length is greater than the length of the commercial vehicle, and their width is greater than the width of the commercial vehicle; one side of the interactive platform 3 is docked with the lifting mechanism 2, and a recessed transverse channel 31 is opened at the docking point of the interactive platform 3 and the lifting mechanism 2. The length of the recessed transverse channel 31 is greater than the width of the vehicle and greater than the width of the AGV transport vehicle 4, and the width is less than the wheelbase of the vehicle and greater than the length of the AGV transport vehicle 4.

[0041] A lifting platform 32 is arranged in the recessed transverse channel 31 of the interactive platform 3 so that commercial vehicles can drive in and out of the interactive platform 3 when the lifting platform 32 is raised. The lifting height of the lifting platform 32 is consistent with the depth of the recessed transverse channel 31 of the interactive platform 3.

[0042] The AGV transporter 4 sneaks into the vehicle chassis from between the front and rear wheels on the side of the car, and its lifting mechanism 42 enables its lifting beam 423 to hit the longitudinal beam of the commercial vehicle chassis. After further lifting, the four wheels of the commercial vehicle are lifted off the ground. The AGV transporter 4 can carry the commercial vehicle and move in the recessed longitudinal conveying channel 12 and the transverse storage channel 13, as well as the lifting mechanism 2 car 22 and the recessed transverse channel 31 of the exchange platform 3.

[0043] Specifically, the body 41 of the AGV transporter 4 is a rectangular parallelepiped, with a length smaller than the distance between the front and rear wheels of the commercial vehicle, a width adapted to the width of the commercial vehicle, and a height adapted to the height of the commercial vehicle chassis and the depth of the recessed structure.

[0044] Specifically, the lifting height of the lifting mechanism 42 of the AGV transport vehicle 4 is sufficient to lift the four wheels of the commodity vehicle off the ground by a certain distance, so that the AGV transport vehicle can move on a plane while carrying the commodity vehicle.

[0045] Specifically, the AGV transport vehicle 4 is provided with a pair of steering wheels and a pair of steering wheels, which give full play to the AGV's omnidirectional operation and precise positioning characteristics, so that the AGV transport vehicle 4 can operate according to a predetermined program in the three-dimensional warehouse body 1.

[0046] Specifically, the lifting mechanism 42 of the AGV transporter 4 consists of vertical push-pull mechanisms 421 arranged on both sides of the vehicle body 41 along the length direction, and a horizontal spacing adjustment mechanism 422 horizontally connected between the vertical push-pull mechanisms 421 on both sides. Specifically, a lifting beam 423 is fixed horizontally to the push-pull end of each vertical push-pull mechanism 421. The multiple vertical push-pull mechanisms 421 on each side are connected to a rigid connection structure 424. The horizontal spacing adjustment mechanism 422 is arranged between the rigid connection structures 424 on both sides of the vehicle body to adjust the spacing between the lifting beams 423. In this embodiment, the horizontal spacing adjustment mechanism 424 is, for example, the rack and pinion drive mechanism shown in the figure, and the rigid connecting rod 424 is vertically connected to the output end of the rack and pinion drive mechanism.

[0047] In the embodiment of the present invention, each vertical push-pull mechanism 421 is designed to be a structure capable of short-distance horizontal movement in the width direction of the vehicle body 41, such as Figure 18-20 The slide rail slider displacement structure shown; the rack and pinion drive mechanism consists of two racks meshing with a corresponding gear, and the gear is fixed on a base in the vehicle body 41. When the gear rotates, based on the meshing relationship between the gear and the rack, the two racks change the spacing between the two rigid connecting rods 424 in the width direction of the vehicle body 41, and the vertical push-pull mechanisms 421 on both sides also move accordingly, thereby realizing the adjustment of the spacing between the two lifting beams 423, so that it can adapt to the width of the longitudinal beams of the chassis of commercial vehicles of different specifications.

[0048] The following takes vehicle entry as an example to illustrate the operation process of the three-dimensional warehouse given in the above embodiment of the present application. The lifting mechanism 2 at the entry and exit ends of the three-dimensional warehouse 1 both adopts a double-parking car 22 to cope with efficient entry and exit operations.

[0049] In terms of the process, commercial vehicles are transported from the main factory to the sea port by car trucks, cage trains or water vessels. After inspection and customs clearance, unmanned straddle carriers or drivers move the commercial vehicles to the interactive platforms 3 on both sides of the lifting mechanism 2 at the entrance of the three-dimensional warehouse body 1. They are then transported to each car storage layer 11 by AGV transport vehicles 4 via the lifting mechanism 2. Then, the AGV transport vehicles 4 transport the commercial vehicles to the target parking space car storage platform 14 through the longitudinal conveying channel 12 and the transverse storage channel 13.

[0050] Specifically, it includes: 1. After the inspection and release of the commercial vehicles at the port, two unmanned straddle carriers will drive to the inspection parking lot of the commercial vehicles at the port according to the instructions, accurately straddle and clamp the target commercial vehicles and drive to the interactive platform 3 on both sides of the lifting mechanism 2 of the three-dimensional warehouse 1.

[0051] During this period, the lifting platform 32 in the recessed transverse channel 31 transverse to the interactive platform 3 is lifted to the same level as the interactive platform 3 .

[0052] 2. Two unmanned straddle carriers, holding the commercial vehicle, simultaneously drive onto the left front and right rear interactive platforms 3 and land. After landing, the unmanned straddle carriers exit the interactive platform 3, and the lifting platform 32 in the recessed transverse channel 31 of the interactive platform 3 descends to the bottom plane.

[0053] 3. The double-parking car 22 of the lifting mechanism 2 carries two AGV transporters 4 from the fourth floor of the stereoscopic warehouse to the first floor. The two AGV transporters 4 simultaneously drive into the recessed transverse channels 31 of the left front and right rear interactive platforms 3 through the car 22, one on the left and one on the right, and are positioned under the chassis of the commercial vehicle. The lifting mechanism 42 lifts the two longitudinal beams of the commercial vehicle chassis until the four wheels of the commercial vehicle are separated from the interactive platform 3. The two AGV transporters 4 each carry a commercial vehicle, one on the left and one on the right, one in front and one behind, and enter the car 22 of the lifting mechanism 2 laterally. The lifting platform 32 at the bottom of the recessed transverse channels 31 of the two interactive platforms 2 on the left and right sides rises again to the same level as the interactive platform 3.

[0054] 4. After the car 22 rises to the fourth floor, two AGV transporters 4 transport the commercial vehicle to the target parking space vehicle storage platform 14 through the longitudinal conveying channel 12 and the transverse storage channel 13, one after the other. After the two AGV transporters 4 reach the target parking space, they retract their lifting mechanisms 42 until the four wheels of the commercial vehicle fall into the vehicle storage platform 14. Then, they drive from the transverse storage channel 13 through the longitudinal conveying channel 12, one after the other, to the entrance of the lifting mechanism 2 and wait.

[0055] 5. Car 22, empty from the fourth floor, stops at the third floor. Two unladen AGVs 4 on the third floor enter the car 22 of the lifting mechanism 2, one in front of the other, and the other behind. Car 22 descends to the first floor. At this point, the second batch of unmanned straddle carriers, carrying the commercial vehicles, have completed the vehicle interaction with the interactive platform 3. The lifting platform 32 of the transverse passage 31 has descended to the bottom of the recessed transverse passage 31. The two AGVs 4 in the car 22 of the lifting mechanism 2, one in front of the left and one in the rear, drive through the transverse passage to enter under the commercial vehicle chassis of the interactive platform 3. Car 22 ascends to the third floor, and the two AGVs 4, carrying the commercial vehicles on their backs, drive one by one to their destination.

[0056] 6. The car 22 rises to the fourth floor, and the two AGV transporters 4 waiting at the entrance enter the car 22 one by one, descend to the first floor and continue to repeat the operation until the warehousing operation is completed.

[0057] The above introduces the warehousing operation method. The outbound operation method has the opposite process to the warehousing operation method, so it will not be described in detail.

[0058] In the above operation process, the purpose of alternating between four layers and three layers is to improve operation efficiency. Alternatively, any layers can be operated alternately to optimize the entire process through existing or innovative algorithms, which is not limited by this application.

[0059] From the perspective of reducing costs and improving efficiency, the efficiency requirements for warehousing are not high, but the efficiency requirements for outbound warehousing are higher. In another embodiment of the present invention, the warehousing lifting mechanism 2 adopts a longitudinal single-parking space car 22, and two interactive platforms 3 are symmetrically arranged on the ground on both sides of the lifting mechanism 2; the outbound lifting mechanism 2 adopts a longitudinal double-parking space car, and two interactive platforms 3 are arranged on the left front and right rear of the ground on both sides of the lifting mechanism 2. Each unit is equipped with 6 AGV transporters 4. During the transportation operation on each floor, the number of AGV transporters 4 can be flexibly deployed according to needs for the transportation of commercial vehicles in and out of the warehouse.

[0060] When the warehousing operation begins, the lifting platforms 32 of the interactive platforms 3 on both sides of the warehousing lifting mechanism 2 rise, the driver drives the commodity car into the interactive platform 3 on the left side to park and then leaves the vehicle, the lifting platform 32 of the interactive platform 3 is lowered, and the 1# AGV transporter 4 in the elevator car 22 of the lifting mechanism 2 enters under the chassis of the commodity car through the recessed transverse channel 31 of the left interactive platform 3. The lifting beam 423 of the 1# AGV transporter 4 lifts the longitudinal beam of the commodity car until the wheels are separated from the interactive platform 3, and the 1# AGV transporter 4 carries the commodity car into the elevator car 22 of the lifting mechanism 2; at this time, another driver drives the commodity car into the interactive platform 3 on the right side to park and then leaves the interactive platform 3, and the lifting platform 32 of the interactive platform 3 is lowered. ; At this time, the lifting mechanism 2 rises to the 6th floor, and the 1# AGV transporter 4 carrying the commodity car drives out of the lifting mechanism 2 and enters the longitudinal conveying channel 12 to the right transverse storage channel 13 of row 17. At this time, the 2# AGV transporter 4 on the left transverse storage channel 13 of row 1 moves into the longitudinal conveying channel 12 and enters the lifting mechanism 2 car 22 to descend to the first floor. The 2# AGV transporter 4 enters under the commodity car chassis through the recessed transverse channel 31 of the right interactive platform 3. The 2# AGV transporter 4 lifts the commodity car's longitudinal beam 423 until the wheels are separated from the interactive platform 3. Then the 2# AGV transporter 4 carries the commodity car and enters the lifting mechanism 2 car 22... and so on. The cycle continues until the warehousing operation is completed.

[0061] At the beginning of the outbound operation, 4 AGV transporters are deployed on the outbound operation layer, such as the 5th floor. AGV #1, AGV #2, AGV #3, and AGV #4 dive into the parking chassis of row 17, right, row 1, right, row 17, left, and row 16, respectively. The lifting mechanism 42 of AGV #1 and AGV #2 lifts the commodity vehicle and moves it into the longitudinal conveying channel 12; the lifting platform 32 of the outbound interactive platform 3 is lowered, and after the lifting mechanism 2 is raised to the 5th floor, AGV #1 and AGV #2 carrying the commodity vehicle are already waiting in the longitudinal conveying channel 12 on the 5th floor, and enter the elevator 22 of the lifting mechanism 2 in turn and descend to the first floor. AGV #1 and AGV #2 carrying the commodity vehicle move from the elevator 22 into the left front and right rear recesses of the interactive platform 3 respectively. In the transverse channel 31, after the lifting mechanisms 42 of AGV 1# and AGV 2 descend and place the merchandise vehicle on the interactive platform 3, AGV 1# and AGV 2# move from the left and right interactive platforms 3 back into the cabin 22; the lifting platform 32 of the interactive platform 3 rises, the driver drives the merchandise vehicle away, and the lifting platform 2 of the interactive platform 3 descends again; at this time, the lifting mechanism 2 rises to the 5th floor, AGV 2# and AGV 1# move out of the cabin 22 and move from the longitudinal conveying channel 12 to the parking chassis of row 17, right, and row 2, right, to continue the outbound operation; AGV 3# and AGV 4#, carrying the merchandise vehicle, move from row 17, left, and row 16, left, into the longitudinal conveying channel 12 and then into the cabin 22, and so on, until the outbound operation is completed.

[0062] Commercial vehicle stereoscopic warehouses are different from urban parking stereoscopic warehouses. First, the cars stored in commercial vehicle stereoscopic warehouses are all new cars, and the number of cars of the same brand and specification is large. Second, commercial vehicle stereoscopic warehouses, especially commercial vehicle stereoscopic warehouses at port roll-on / roll-off terminals, are centralized for entry and exit. In view of the characteristics of commercial vehicles, the present invention, in combination with fire protection regulations, has designed a digital stereoscopic warehouse specifically for commercial vehicle stereoscopic storage that has a simple and smooth operation process, extremely high storage density, extremely high operation efficiency, flexible deployment of transportation resources, zero-carbon warehouses, compliance with fire protection regulations, and low investment and operating costs. It breaks through the constraint that traditional car flat movement can only be achieved by clamping car tires. It sneaks under the car chassis from the side of the car and uses the method of lifting the commercial vehicle longitudinal beam through the innovative design of the entire process to achieve the purpose of commercial vehicle flat movement, thereby achieving the above-mentioned many positive effects.

[0063] It should be pointed out that the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
