Description

Technical Field

[0001] The present invention relates to the technical field of port logistics warehousing equipment, and in particular to a ro-ro terminal automotive three-dimensional yard device. In addition, it also relates to an integrated three-dimensional yard device for automobiles and containers. Background Art

[0002] The characteristics of the ro-ro terminal automotive yard are the problem of temporary parking of automobiles during the collection and distribution of automobiles. Automobile collection means that the commercial automobiles are centrally stored in the automotive yard of the ro-ro terminal before being loaded onto the ship. The commercial automobiles for collection are generally those of automobile manufacturers that can be covered by the port, involving as few as 2 to 3 manufacturers and as many as more than a dozen automobile manufacturers. Moreover, the number of commercial automobiles in each batch collected by these manufacturers is relatively large, ranging from a few hundred to several thousand, and they are of the same brand. Automobile distribution means that the commercial automobiles (mostly imported automobiles) are centrally stored in the automotive yard of the ro-ro terminal after being unloaded from the ship. The commercial automobiles for distribution are for the consumer market of the major urban automotive 4S stores that can be covered by the port, and the consumers are all individualized, which results in the problems of many brands, many models, and small batches of the commercial automobiles for distribution. Each 4S store imports as few as a few or as many as dozens of commercial automobiles each time. And generally in China, the number of commercial automobiles collected at the ro-ro terminal is far greater than the number of commercial automobiles for distribution. When loading the commercial automobiles for collection onto the ship, it is only necessary to drive the automobiles into the cabin one by one from the automotive yard in sequence; while when distributing the commercial automobiles for distribution, the randomly coming 4S stores pick up the automobiles and leave the automotive yard.

[0003] Therefore, in view of the extremely large contrast between the collection and distribution of commercial automobiles at the automotive ro-ro terminal, it is very necessary to research and develop a highly efficient, high-density, and low-investment commercial automobile three-dimensional yard device that can basically meet the characteristics of both collection and distribution. Summary of the Invention

[0004] The purpose of the present invention is to propose a port ro-ro terminal commercial automobile three-dimensional yard device that can meet the characteristics of both collection and distribution in view of the problems of large land occupation and low efficiency of the ground plane automotive yard adopted by the existing ro-ro terminal, high cost, low efficiency, and low space utilization rate of the self-propelled (including AGV) three-dimensional parking lot, and high cost, low space utilization rate, and high operation and maintenance cost of the roadway-type shelf three-dimensional automotive garage. And in combination with the characteristics of the top-opening container three-dimensional yard device, an integrated three-dimensional yard device for automobiles and containers is designed to achieve the effects of high efficiency, high density, and low investment.

[0005] On the one hand, the present invention provides a three-dimensional storage device for commercial vehicles at a port ro-ro terminal to achieve the above object. The technical solution adopted is as follows: It includes a reinforced concrete or steel structure framework (hereinafter referred to as the framework). Inside the framework, there are multiple layers of vehicle storage areas, which are divided into a port collection vehicle storage area and a port evacuation vehicle storage area. Each layer of the vehicle storage area is arranged with a number of vehicle conveying lines in parallel (such as 24, including 18 port collection vehicle conveying lines and 6 port evacuation vehicle conveying lines). Each vehicle conveying line evenly carries a number of vehicles (such as 29). The port collection vehicle conveying lines do not have car carriers and adopt conveying forms such as crawlers. The vehicles are directly stored on the crawler conveying lines. While the port evacuation vehicle conveying lines are provided with car carriers, and longitudinal and transverse transfer mechanisms are respectively arranged at both ends and in the middle of the vehicle conveying lines in the port evacuation vehicle storage area, so that the vehicles in the port evacuation vehicle storage area can achieve a circulation function between two adjacent vehicle conveying lines. At the front end and / or rear end of the conveying direction of the vehicle conveying line, there is a three-dimensional storage vehicle entrance and exit. The three-dimensional storage vehicle entrance and exit is provided with a vehicle lifting mechanism. On the lifting plate of the lifting mechanism, there are transverse guide rails and a longitudinal transmission mechanism. The longitudinal transmission mechanism is slidably installed on the transverse guide rails, facilitating the vehicle to be successively conveyed on the lifting mechanism and the multiple vehicle conveying lines on multiple layers. This solution, by setting multiple vehicle conveying lines in each layer of the vehicle storage area, uniformly conveys and stores the vehicles on them. Each vehicle conveying line is closely arranged, and the vehicles are closely and safely spaced on the vehicle conveying line for overall conveying, greatly improving the vehicle storage density and significantly reducing the manufacturing cost and operation and maintenance cost.

[0006] Furthermore, for port collection vehicles, there is no need to configure car carriers. At least two adjacent vehicle conveying lines on the same parking layer form a conveying unit. The longitudinal transmission mechanism on the lifting plate of the lifting mechanism can be horizontally moved along the transverse guide rails driven by a motor to be successively docked with each vehicle conveying line in the conveying unit. The transmission mode of the longitudinal transmission mechanism is the same as that of the port collection vehicle conveying line, enabling the vehicles to enter and exit directly, so as to realize that the stored vehicles can be conveyed on the lifting mechanism and the vehicle conveying line, achieving the purpose that the same lifting mechanism is shared by the same conveying unit on different parking layers. For port evacuation vehicles, car carriers need to be configured. Longitudinal and transverse transfer mechanisms are respectively arranged at both ends and in the middle of the port evacuation vehicle conveying lines on the same parking layer, and the position on the longitudinal and transverse transfer mechanism in the middle part is set as an empty position. One is to divide the port evacuation vehicle storage area into two parts (such as the east area and the west area), and the other is that the vehicle conveying lines in the two areas share a circulation space, so as to achieve the purpose that the car carriers (with or without vehicles) on two adjacent vehicle conveying lines in the same area (east area or west area) can be circulated and conveyed. The transmission mode of the longitudinal transmission mechanism on the lifting plate of the lifting mechanism is the same as the transmission mode of the port evacuation vehicle conveying line for conveying the car carriers, so as to achieve the purpose of circulating and alternately conveying the longitudinal transmission mechanism of the lifting mechanism and the car carriers (with or without vehicles) on the multiple vehicle conveying lines of the conveying unit.

[0007] Furthermore, three adjacent parallel vehicle conveying lines form a conveying unit. For vehicles destined for the port, there is no need to configure a car carrier. The longitudinal transmission mechanism on the lifting plate of the lifting mechanism can move horizontally along the transverse guide rail driven by a motor and dock sequentially with each conveying line in the conveying unit, facilitating the storage and direct-in-and-direct-out conveyance of vehicles. For vehicles leaving the port, a car carrier needs to be configured. Horizontal and vertical transfer mechanisms are respectively arranged at both ends and in the middle of the three conveying lines in the conveying unit, and the position on the horizontal and vertical transfer mechanism in the middle part is set as an empty position, so as to achieve the purpose that the first vehicle conveying line and the second vehicle conveying line form a clockwise cycle, and the third vehicle conveying line and the second vehicle conveying line form a counterclockwise cycle. At the same time, the longitudinal transmission mechanism on the lifting plate of the lifting mechanism moves horizontally along the transverse guide rail driven by a motor and docks sequentially with each conveying line in the conveying unit to achieve the purpose of cyclic and alternating conveyance. For the storage area of vehicles leaving the port, it is divided into two vehicle storage areas (such as the east area and the west area) by the horizontal and vertical transfer mechanism in the middle part of the conveying unit, which is conducive to the access efficiency of vehicles leaving the port.

[0008] Furthermore, the transverse guide rail and the longitudinal transmission mechanism are arranged on the lifting plate of the lifting mechanism. The initial static position of the longitudinal transmission mechanism is defaulted to the middle position of the transverse guide rail on the lifting plate. The longitudinal transmission mechanism moves horizontally to the left or right along the transverse guide rail driven by a motor and docks sequentially with each conveying line in the conveying unit. For the storage area of vehicles destined for the port, the transmission mode of the longitudinal transmission mechanism of the lifting mechanism is the same as that of the vehicle conveying line in the storage area of vehicles destined for the port. For the storage area of vehicles leaving the port, the transmission mode of the longitudinal transmission mechanism of the lifting mechanism is the same as that of the car carrier on the vehicle conveying line in the storage area of vehicles leaving the port. Each conveying unit formed by multiple vehicle conveying lines on each layer shares a vehicle entrance and exit and a lifting mechanism with the vertically corresponding conveying units on other layers in the frame. The lifting of the lifting mechanism and the horizontal movement of the longitudinal transmission mechanism are flexible. One lifting mechanism serves the conveying units arranged vertically in multiple layers, reducing the number of lifting mechanisms set and lowering the cost.

[0009] Furthermore, each vehicle conveying line in the frame can be a single conveying line or composed of multiple identical conveying lines. The conveying line can be in the form of chain drive, plate chain drive, caterpillar drive, friction wheel drive, etc. However, for the transmission mode of the conveying line in the storage area of vehicles leaving the port, it should be adapted to the transmission mode of the car carrier.

[0010] Furthermore, for the storage area of vehicles leaving the port, each car carrier is exactly the same. Its length is about 4500 mm, width is about 2200 mm, and the thickness should be such that it is not easily deformed according to different materials. The reverse side of the car carrier can be compounded with high-friction coefficient materials such as polymer materials to form a friction layer. To cooperate with the friction wheel drive, the reverse side of the car carrier can be designed in the form of two transverse guide rails and two longitudinal guide rails.

[0011] Furthermore, angle steel rails are provided on both sides of each vehicle conveyor line in the vehicle storage area for port evacuation. The vehicle conveyor line carries the vehicle-carrying board (with or without vehicles) and moves in the angle steel rails.

[0012] On the other hand, the present invention also provides an integrated three-dimensional yard device for port vehicles and containers. The lower layer (such as the 1st - 4th floors) of the integrated yard device is designed as the three-dimensional yard for roll-on / roll-off terminal vehicles as described above, and the upper layer (such as the 5th - 14th floors) is designed as a container three-dimensional yard. The container three-dimensional yard adopts a composite container three-dimensional yard device design (filed in a separate application with the application number 2023102634049). The external dimensions of the vehicle three-dimensional yard are the same as or slightly longer than those of the composite container yard, and the working surface of the container three-dimensional yard is on both sides in the length direction of the integrated yard, while the working surface (vehicle entrance and exit) of the vehicle three-dimensional yard is at both ends in the width direction of the integrated yard.

[0013] The container three-dimensional yard and the vehicle three-dimensional yard share a frame. A sealed partition is provided at the bottom of the container three-dimensional yard to separate the container three-dimensional yard from the vehicle three-dimensional yard. Here, the solution in the patent with the application number 2023102634049 is introduced. Specifically, the frame has an internally open space at the top. A plurality of unit partition walls are provided in the frame. The unit partition walls are arranged along the X direction of the frame. The internal space of the frame is divided into a plurality of container yard units by the unit partition walls. A container yard unit is formed between two adjacent unit partition walls. The X direction of a container yard unit is adapted to the length of the container, and multiple containers can be placed in the Y and Z directions. An X-direction main track is provided at the top of the frame, and a double gantry bridge crane is installed on the X-direction main track. A number of pairs of vertical container rails are provided on the inner walls on both sides of each container yard unit. A slideway shaft with the width of the container as the standard is formed between two opposite pairs of container rails. The height of the slideway shaft is the same as the height of the frame. The gantry span of the double gantry bridge crane is the same as the width of the frame. The gantry height should be greater than or equal to the height of two containers. One end of the double gantry bridge crane extends out of one side of the frame and extends a distance greater than the width of two containers. A container buffer platform is provided on the outer side of the bottom of the double gantry bridge crane. At the same time, two bridge crane trolleys are provided on the gantry truss of the double gantry bridge crane to move. The height and length of the unit partition wall are the same as the height and width of the frame. A number of layers of Y-direction maintenance channels consistent with the height of the container are provided in the unit partition wall. The width is such that a person can pass through conveniently. A ladder channel is provided between two adjacent layers of Y-direction maintenance channels. A passenger and cargo elevator is provided in the middle of both ends in the X direction of the frame. The passenger and cargo elevator can lead to any layer of the Y-direction maintenance channel, facilitating the work of maintenance personnel, such as loosening frame screws, replacing rails, and anti-corrosion operations, etc., in order to facilitate the maintenance of the entire three-dimensional yard device.

[0014] The above content is only the mechanical structure design principle of the ro-ro terminal automotive three-dimensional storage yard device and the integrated automotive and container three-dimensional storage yard device. Its electrical control can adopt PLC technology. At the same time, in order to realize digitalization and intelligentization of the entire device, a series of digital technologies and algorithms such as visual sensing, laser detection, infrared rays, 5G communication, Beidou positioning, and yard management system can be adopted.

[0015] As can be seen from the above technical solutions, the present invention has the following advantages:

[0016] This solution provides a ro-ro terminal automotive three-dimensional storage yard device. By dividing each layer of the automotive storage area into two automotive storage areas with different functions, namely the port gathering automotive storage area and the port discharging automotive storage area, and arranging multiple automotive conveying lines, the conveying lines uniformly convey and store the automobiles thereon. Each conveying line is closely arranged, and the automobiles are closely and safely spaced on the conveying line, greatly improving the automotive storage density. In the port gathering automotive storage area, no car carrier is set, and an efficient direct-in and direct-out conveying mode of the automotive conveying line is adopted. In the port discharging automotive storage area, a car carrier is set, and a high-efficiency "car picking" conveying mode of circular entry and exit is adopted. And only one lifting mechanism is set in each vertical conveying unit. The overall structure of this technical solution is simple, which can greatly reduce the manufacturing cost and maintenance cost, achieving the effects of high port gathering and discharging efficiency of automobiles, high automotive stacking density, and low investment and operation cost.

[0017] This solution also provides an integrated three-dimensional storage yard device for port automobiles and containers. In some scenarios where the distance between the ro-ro terminal and the container terminal in a seaport is very close, and even there is a mixed operation of the ro-ro terminal and the container terminal. On the one hand, the ro-ro terminal occupies a huge area and the turnover speed of the automotive yard is much lower than that of the container yard in the container terminal. On the other hand, the yard area of the container terminal is seriously insufficient. By realizing the transfer of automobiles and containers in the same integrated three-dimensional yard, while making full use of the yard space, it can reduce both the land investment in the container yard and the investment in the frame structure of the automotive yard, and can bring great social and economic benefits. Among them, the specific effects of this container three-dimensional yard can be referred to the patent document with the application number 2023102634049. Brief Description of the Drawings

[0028] To make the objectives, features, and advantages of the present invention more obvious and understandable, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the accompanying drawings in the specific embodiments. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent. Specific embodiment 1

[0030] As Figures 1 to 6As shown in the figure, this specific implementation mainly aims at the entry and exit of vehicles for port consolidation and port evacuation, and provides a three-dimensional vehicle storage yard device 1 for a roll-on / roll-off terminal. It includes a reinforced concrete frame or a steel structure frame (hereinafter referred to as the frame). Inside the frame, there are multiple layers of vehicle storage areas, which are divided into a port consolidation vehicle storage area and a port evacuation vehicle storage area. A number of vehicle conveyor lines (such as 24, including 18 port consolidation vehicle conveyor lines 4 and 6 port evacuation vehicle conveyor lines 5) are arranged side by side in each vehicle storage area. A number of vehicles (such as 29 vehicles on the port consolidation line and 28 vehicles on the port evacuation line) are evenly placed on each vehicle conveyor line. The port consolidation vehicle conveyor line 4 is not equipped with a car carrier 6, while the port evacuation vehicle conveyor line 5 is equipped with a car carrier 6. Horizontal and vertical transfer mechanisms 51 are respectively arranged at both ends and in the middle of the port evacuation vehicle conveyor line 5 in the port evacuation vehicle storage area, enabling the vehicles in the port evacuation vehicle storage area to achieve a circulation function between two adjacent port evacuation vehicle conveyor lines 5. Vehicle three-dimensional yard entrances and exits 2 are provided at the front end and / or the rear end of the conveying direction of the vehicle conveyor line. A vehicle lifting mechanism 3 is arranged on the operation surface of the three-dimensional yard. The lifting mechanism 3 facilitates the conveyance of vehicles between the lifting mechanism and the vehicle conveyor line. The lifting mechanism 3 is used to lift the vehicle to any layer or place the vehicle from any layer at the vehicle three-dimensional yard entrances and exits 2.

[0031] Among them, for the port-collecting cars, there is no need to configure the car loading plate 6. At least two adjacent port-collecting car conveying lines 4 on the same parking floor form a conveying unit. The longitudinal transmission mechanism 32 on the lifting plate 30 of the lifting mechanism 3 moves laterally along the transverse guide rail 31 under the drive of the motor and connects with each port-collecting car conveying line 4 in the conveying unit in turn, so that the car can go in and out directly, so that the stored cars can be continuously conveyed on the lifting mechanism 3 and the port-collecting car conveying line 4, so as to achieve the purpose of sharing a lifting mechanism 3 with the same conveying unit on different parking floors. For the port-clearing vehicles, a vehicle-carrying plate 6 is required to be configured, and longitudinal and transverse transfer mechanisms 51 are respectively arranged at both ends and in the middle of the port-clearing vehicle conveying line 5 of the same parking floor, and the position on the longitudinal and transverse transfer mechanism 51 located in the middle is set to an empty space, one is to divide the port-clearing vehicle storage area into two (such as the east area and the west area), and the other is that the port-clearing vehicle conveying lines 5 of the two areas share a circulation space, so as to achieve the purpose of cyclic transportation of the vehicle-carrying plates 6 (with or without vehicles) on two adjacent port-clearing vehicle conveying lines 5 in the same area (east area or west area). The longitudinal transmission mechanism 32 on the lifting plate 30 of the lifting mechanism moves laterally along the transverse guide rail 31 under the drive of the motor and is sequentially docked with each port-clearing vehicle conveying line 5 in the conveying unit, so as to achieve the purpose of cyclic alternating transportation of the longitudinal transmission mechanism 32 of the lifting mechanism 3 and the vehicle-carrying plates 6 (with or without vehicles) on multiple port-clearing vehicle conveying lines 5 of the conveying unit and the same conveying unit of different parking floors share a lifting mechanism 3. The transmission mode of the longitudinal transmission mechanism 32 on the lifting plate 30 of the lifting mechanism is consistent with the transmission mode of the vehicle carrying plate 6 on the port vehicle conveying line 5. Specifically, three adjacent vehicle conveying lines arranged side by side form a conveying unit. For the port-collecting vehicles, there is no need to configure the vehicle carrying plate 6. The longitudinal transmission mechanism 32 on the lifting plate 30 of the lifting mechanism moves laterally along the lifting mechanism transverse guide rail 31 under the drive of the motor, and is respectively connected with each port-collecting vehicle conveying line 4 in the conveying unit in sequence, so that the stored vehicles are transported in and out directly. For the port-clearing vehicles, a vehicle-carrying plate 6 is required. The two ends and the middle of the three port-clearing vehicle conveying lines 5 in the conveying unit are respectively provided with longitudinal and transverse transfer mechanisms 51, and the position on the longitudinal and transverse transfer mechanism 51 in the middle is set to an empty position, so as to achieve the purpose of the first conveying line and the second conveying line forming a clockwise cycle, and the third conveying line and the second conveying line forming a counterclockwise cycle. The longitudinal transmission mechanism 32 on the lifting plate 6 of the lifting mechanism can move laterally along the transverse guide rail 31 under the drive of the motor and dock with each vehicle conveying line 5 in the conveying unit in turn, so as to achieve the purpose of cyclic alternating transportation of the vehicle-carrying plate (with or without a vehicle); for the port-clearing vehicle storage area, the longitudinal and transverse transfer mechanism 51 in the middle of the conveying unit is used to divide it into two vehicle storage areas (such as the east area and the west area), which is beneficial to the storage and retrieval efficiency of the port-clearing vehicles.

[0032] Among them, the lifting plate 30 of the lifting mechanism is provided with a pair of transverse guide rails 31 and a longitudinal transmission mechanism 32. The longitudinal transmission mechanism 32 is slidably installed on the transverse guide rails 31. The initial default position of the longitudinal transmission mechanism 32 is at the center position of the lifting plate 30 of the lifting mechanism 3. Driven by the motor, the longitudinal transmission mechanism 32 can move horizontally along the transverse guide rails 31 and is sequentially docked with each automobile conveying line of the conveying units on each parking floor. For the container port vehicle storage area, the transmission mode of the longitudinal transmission mechanism 32 of the lifting mechanism 3 is the same as that of the container port vehicle conveying line 4 in the container port vehicle storage area. For the vehicle outbound storage area, the transmission mode of the longitudinal transmission mechanism 32 of the lifting mechanism 3 is the same as that of the vehicle outbound conveying line 5 in the vehicle outbound storage area. The conveying units formed by multiple automobile conveying lines on each floor share a three-dimensional vehicle yard entrance and exit 2 and a lifting mechanism 3 with the vertically corresponding conveying units on other floors in the frame. The lifting plate 30 of the lifting mechanism 3 can carry the longitudinal transmission mechanism 32 to lift and move horizontally flexibly. One lifting mechanism 3 serves the conveying units arranged vertically corresponding to multiple floors, reducing the number of lifting mechanisms 3 set and lowering the cost.

[0033] Among them, each automobile conveying line in the frame can be a single conveying line or composed of multiple identical conveying lines. The conveying line can be in the form of chain drive, plate chain drive, track drive, friction wheel drive, etc. However, for the conveying line drive mode in the vehicle outbound storage area, it should be adapted to the drive mode of the car carrier 6.

[0034] For the vehicle outbound storage area, each car carrier 6 is exactly the same. Its length is about 4500 mm, width is about 2200 mm, and the thickness should be such that it is not easy to deform according to different materials. The reverse side of the car carrier 6 can be compounded with high-friction coefficient materials such as polymer materials to form a friction layer. To cooperate with the friction wheel drive, the reverse side of the car carrier 6 can be designed in the form of two transverse guide rails and two longitudinal guide rails. Angle steel guide rails are provided on both sides of each automobile conveying line in the vehicle outbound storage area, and the conveying line carries the car carrier (with or without a vehicle) to move in the angle steel guide rails.

[0035] Its working principle is as follows: Taking a conveying unit formed by three automobile conveying lines as an example.

[0036] When the port-bound vehicle enters the storage area (i.e., when it moves from the vehicle factory to the port for waiting to be loaded onto the ship), the driver parks the vehicle on the longitudinal transmission mechanism 32 of the lifting mechanism 3 in the port-bound vehicle storage area. The lifting mechanism 3 raises the vehicle to a certain level and stops. The motor drives the longitudinal transmission mechanism 32 to move horizontally along the transverse movement guide rail 31 until it docks with the first port-bound vehicle conveyor line 4 in the conveying unit. At this time, the longitudinal transmission mechanism 32 and the first port-bound vehicle conveyor line 4 synchronously step forward by the distance of one vehicle, and convey the vehicle into the port-bound vehicle storage area. Then the lifting mechanism 3 descends to the ground level (at this time, the longitudinal transmission mechanism 32 is horizontally moved to the center position of the lifting plate 30) to continue receiving vehicles. The lifting mechanism 3 raises the second vehicle to this level and stops. The motor drives the longitudinal transmission mechanism 32 to move horizontally along the transverse movement guide rail 31 again until it docks with the first port-bound vehicle conveyor line 4 in the conveying unit and conveys the second vehicle into the port-bound vehicle storage area. This process repeats until the first port-bound vehicle conveyor line 4 is full (e.g., 29 vehicles). The same applies to the second port-bound vehicle conveyor line 4 and the third port-bound vehicle conveyor line 4.

[0037] When the port-bound vehicle exits the storage area (i.e., when it is loaded onto the ship), the process of the vehicle exiting the storage area is the reverse of the vehicle entering the port.

[0038] With the cooperation of the lifting mechanism 3 and the longitudinal transmission mechanism 32 that can move horizontally along the transverse movement guide rail 31 on the lifting plate 30 of the lifting mechanism, the port-bound vehicle enters and exits the storage area in a direct-in and direct-out manner.

[0039] When the port-drayage truck enters the storage area (i.e., when the imported vehicle is unloaded from the ship), the first port-drayage truck conveyor line 5 of a certain conveyor unit in the port-drayage truck storage area moves step by step towards the middle longitudinal and transverse transfer mechanism 51 by a distance equal to one vehicle carrier 6, transporting an empty vehicle carrier 6 to the middle longitudinal and transverse transfer mechanism 51. The middle longitudinal and transverse transfer mechanism 51 then laterally moves the empty vehicle carrier 6 to the second port-drayage truck conveyor line 5 and docks with it. The first port-drayage truck conveyor line 5 then moves step by step towards the middle longitudinal and transverse transfer mechanism 51 by a distance equal to one vehicle carrier 6 again, transporting another empty vehicle carrier 6 to the middle longitudinal and transverse transfer mechanism 51. At this time, two positions for vehicle carriers 6 become vacant near the vehicle lifting mechanism 3 on the first port-drayage truck conveyor line 5 (i.e., the two vacant positions of the middle longitudinal and transverse transfer mechanism 51 between the first and second port-drayage truck conveyor lines 5 are transferred here). The lifting mechanism 3 of a certain conveyor unit in the port-drayage truck storage area first rises to this level, and the longitudinal transmission mechanism 32 at the center of the lifting plate 30 docks with the second port-drayage truck conveyor line 5. The second port-drayage truck conveyor line 5 as a whole (including the middle longitudinal and transverse transfer mechanism 51 and the longitudinal transmission mechanism 32) step by step transports an empty vehicle carrier 6 to the longitudinal transmission mechanism 32 on the lifting plate 30 of the lifting mechanism 3 (at this time, the empty vehicle carrier 6 on the middle longitudinal and transverse transfer mechanism 51 of the first port-drayage truck conveyor line 5 is laterally moved to the middle longitudinal and transverse transfer mechanism 51 of the second port-drayage truck conveyor line 5). The lifting plate 30 of the lifting mechanism 3 descends to the ground, and the driver drives the vehicle onto the vehicle carrier 6 of the lifting mechanism 3. The lifting plate 30 of the lifting mechanism 3 lifts the vehicle to this level and stops. The motor drives the longitudinal transmission mechanism 32 to laterally move the vehicle carrier 6 carrying the vehicle along the transverse movement guide rail 31 to dock with the first port-drayage truck conveyor line 5. The longitudinal transmission mechanism 32 of the lifting mechanism 3 and the first port-drayage truck conveyor line 5 (including the middle longitudinal and transverse transfer mechanism 51) as a whole move step by step towards the inside of the storage area by a distance equal to one vehicle carrier 6. At this time, the vehicle carrier 6 carrying the vehicle is input onto the first port-drayage truck conveyor line 5 in the port-drayage truck storage area, and at the same time, an empty vehicle carrier 6 is also transported to the middle longitudinal and transverse transfer mechanism 51 on the first port-drayage truck conveyor line 5. After the lifting mechanism 3 transports a vehicle to the first port-drayage truck conveyor line 5, the motor drives the longitudinal transmission mechanism 32 to laterally move along the transverse movement guide rail 31 to dock with the second port-drayage truck conveyor line 5. The second port-drayage truck conveyor line 5 (including the middle longitudinal and transverse transfer mechanism 51 and the longitudinal transmission mechanism 32) as a whole moves step by step towards the longitudinal transmission mechanism 32 on the lifting plate 30 of the lifting mechanism 3 by a distance equal to one vehicle carrier 6, and another empty vehicle carrier 6 is transported to the longitudinal transmission mechanism 32 on the lifting plate 30 of the lifting mechanism 3. The lifting plate 30 of the lifting mechanism 3 descends to the ground to continue receiving vehicles, and so on in a cycle. The first and second port-drayage truck conveyor lines 5 rotate step by step clockwise under the coordination of the middle longitudinal and transverse transfer mechanism 51 until the first port-drayage truck conveyor line 5 (excluding the middle longitudinal and transverse transfer mechanism 51) is filled with vehicles. At this time,At a distance of two empty spaces of the car-carrying plates 6 from the lifting mechanism 3 on the second port-connecting automobile conveyor line 5, the system will automatically move the second port-connecting automobile conveyor line 5 (including the longitudinal and transverse transfer mechanism 51 between the first and the second port-connecting automobile conveyor lines 5) as a whole two car-carrying plate 6 distances out of the field. At this time, the longitudinal and transverse transfer mechanism 51 between the second and the third port-connecting automobile conveyor lines 5 is in a state of two empty spaces. After the lifting mechanism 3 completes the entry of the automobile on the first port-connecting automobile conveyor line 5, the motor drives the longitudinal transmission mechanism 32 to move horizontally along the transverse guide rail 31 to the second port-connecting automobile conveyor line 5 and dock with it. The second port-connecting automobile conveyor line 5 (including the longitudinal transmission mechanism 32 of the lifting mechanism 3) moves forward one car-carrying plate 6 distance towards the longitudinal transmission mechanism 32 on the lifting plate 30 of the lifting mechanism 3. (At this time, the third port-connecting automobile conveyor line 5, including its corresponding longitudinal and transverse transfer mechanism 51, moves forward one car-carrying plate 6 distance into the field, and there is an empty car-carrying plate 6 on its longitudinal and transverse transfer mechanism 51.) An empty car-carrying plate 6 enters the longitudinal transmission mechanism 32 of the lifting mechanism 3 again. (At this time, the longitudinal and transverse transfer mechanism 51 corresponding to the third port-connecting automobile conveyor line 5 horizontally moves the empty car-carrying plate 6 on it to the position of the second conveyor line 5.) The lifting plate 30 of the lifting mechanism 3 descends to the ground, and the automobile drives onto the car-carrying plate 6 on the longitudinal transmission mechanism 32 of the lifting mechanism 3. After the lifting plate 30 of the lifting mechanism 3 rises to this layer and stops, the motor drives the longitudinal transmission mechanism 32 to move horizontally along the transverse guide rail 31 to the third port-connecting automobile conveyor line 5 and dock with it. The third port-connecting automobile conveyor line 5 (including the longitudinal transmission mechanism 32 of the lifting mechanism 3 and the corresponding longitudinal and transverse transfer mechanism 51) moves forward one car-carrying plate 6 distance into the field, and conveys the car-carrying plate 6 carrying the automobile onto the third port-connecting automobile conveyor line 5. In this way, the third and the second port-connecting automobile conveyor lines 5 rotate step by step counterclockwise under the coordination of the longitudinal and transverse transfer mechanism 51 until the third and the second port-connecting automobile conveyor lines 5 (excluding the longitudinal and transverse transfer mechanism 51) are full of automobiles.

[0040] When the port-connecting automobiles leave the field (i.e., when the customers pick up the cars), in the port-connecting automobile storage area, the cars of the same customer should be stored on the same layer and in the same conveying unit and stored in sequence. To improve the departure efficiency, for the three port-connecting automobile conveyor lines 5 of the same conveying unit, under the coordination of the end longitudinal and transverse transfer mechanism 51 and the middle longitudinal and transverse transfer mechanism 51, the first and the second port-connecting automobile conveyor lines 5 can either step and circulate clockwise or step and circulate counterclockwise, and the third and the second port-connecting automobile conveyor lines 5 can either step and circulate counterclockwise or step and circulate clockwise, and the lifting plate 30 of the lifting mechanism 3 and the longitudinally movable longitudinal transmission mechanism 32 cooperate in operation.

[0042] Such as Figure 7 And Figure 8As shown in the figure, this specific embodiment provides an integrated three-dimensional yard device for port trucks and containers. The lower layer (such as the 1st - 4th floors) of the integrated yard device is designed as the above-mentioned port truck three-dimensional yard, and the upper layer (such as the 5th - 14th floors) is designed as a container three-dimensional yard. The container three-dimensional yard adopts a composite container three-dimensional yard device design (already applied for in a separate case, application number 2023102634049). The external dimensions of the truck three-dimensional yard are the same as or slightly longer than those of the composite container yard, and the working surface of the container three-dimensional yard is on both sides of the integrated yard in the length direction, while the working surface of the truck three-dimensional yard (truck entrance and exit) is at both ends of the integrated yard in the width direction.

[0043] The container three-dimensional yard and the truck three-dimensional yard share a framework. A sealed partition is provided at the bottom of the container three-dimensional yard to separate the container three-dimensional yard from the truck three-dimensional yard. Here, the solution in the patent with the application number 2023102634049 is introduced. Specifically, the framework has an internally open space at the top. A plurality of unit partition walls are provided in the framework, and the unit partition walls are arranged along the X - direction of the framework. The unit partition walls divide the internal space of the framework into multiple container yard units. A container yard unit is formed between two adjacent unit partition walls. The X - direction of a container yard unit is adapted to the length of the container, and multiple containers can be placed in the Y - direction and Z - direction. An X - direction main track is provided at the top of the framework, and a double - gantry bridge crane is installed on the X - direction main track. A number of pairs of vertical container guide rails are provided on the inner walls on both sides of each container yard unit. A slideway shaft with the width of the container as the standard is formed between two opposite pairs of container guide rails, and the height of the slideway shaft is the same as the height of the framework. The gantry span of the double - gantry bridge crane is the same as the width of the framework, and the gantry height should be greater than or equal to the height of two containers. One end of the double - gantry bridge crane extends out of one side of the framework and extends a distance greater than the width of two containers. A container buffer platform is provided on the outer side of the bottom of the double - gantry bridge crane. At the same time, two bridge crane trolleys are provided on the gantry truss of the double - gantry bridge crane to move. The height and length of the unit partition walls are the same as the height and width of the framework. A number of layers of Y - direction maintenance channels with the same height as the container are provided in the unit partition walls, and the width is such that a person can pass through conveniently. A ladder channel is provided between two adjacent layers of Y - direction maintenance channels. A passenger and freight elevator is provided in the middle of both ends of the framework in the X - direction. The passenger and freight elevator can lead to any layer of the Y - direction maintenance channel, facilitating the work of maintenance personnel, such as loosening of framework screws, replacement of guide rails, and anti - corrosion operations, so as to facilitate the inspection and maintenance of the entire three - dimensional yard device.
