Four loading platforms 53 are provided on the top of the short base frame 51, and a second scissor-type telescopic frame 52 is provided between the bottom of the four loading platforms 53 and the short base frame 51.

[0035] The short chassis 51 moves along the ground rail 1 , and the second scissor-type telescopic frame 52 drives the loading platform 53 to move up and down, and the fork groove 15 is placed on the working area 25 by the descent of the four loading platforms 53 .

[0037] In a preferred embodiment, the telescopic cantilever beam truss 8 includes a fixed beam 81, and fixed beams 81 are fixedly installed on the inner walls of the three-dimensional storage racks 2 at the top of both sides of the lower area 23. The fixed beams 81 are slidably clamped with extended arm beams 82, and both ends of the extended arm beams 82 are rotatably clamped with a rotating shaft 84, and a rolling wheel 83 is installed on the rotating shaft 84. The rolling wheel 83 is rotatably clamped in the inner wall of the fixed beam 81, and two Y-axis walking frames 89 are fixedly installed between the two extended arm beams 82.

[0038] In a preferred embodiment, rollers for clamping the Y-axis walking frame 89 are installed at both ends of the X-axis walking frame 87, motors connected to the rollers are installed on the extended arm beam 82 and the X-axis walking frame 87, and the number of the first manipulator frames 85 is eight evenly distributed.

[0039] The first manipulator frame 85 is driven to rise and fall by the first scissor-type telescopic frame 88, thereby adsorbing the bottom beam 16 and the non-standard bottom beam. The movement of the beam is realized by the movement of the X-axis walking frame 87 and the extension arm beam 82, and the loading is realized.

[0040] In a preferred embodiment, the top truss 6 includes a column 61, which is fixedly installed on the ground. A hanging beam 62 is fixedly installed on the top of the column 61, and a traveling beam 63 is installed between the bottoms of the hanging beam 62. An electric hoist 64 is installed on the traveling beam 63, and a second manipulator frame 65 is installed at the bottom of the electric hoist 64.

[0041] Through the above technical solution, the second electromagnetic suction cup 66 is able to load the fork groove 15 and the bottom side beam 17 by moving and extending the electric hoist 64 .

[0042] In a preferred embodiment, the chain conveyor mechanism 7 includes a lifting frame 72, a lifting frame 72 is installed on one side of the upper area 24 close to the working area 25, and a fixed frame 74 is installed on the other side of the upper area 24, and a plurality of transmission shafts 75 are rotatably sleeved on the lifting frame 72 and the fixed frame 74, and a chain sprocket set 71 is installed on the transmission shaft 75, and side fixing frames 76 are fixedly installed at both ends of the lifting frame 72 and the fixed frame 74, and a lifting frame 73 is installed on the top of the lifting frame 72 through a cylinder.

[0043] Through the above technical solution, the loading operation of each beam and trough in the working area and the replenishing operation of each stack are carried out simultaneously. During the loading operation, the top truss 6 on the top of the fork slot stack 9 simultaneously lifts four fork slots 15 and transports them to the four loading platforms 53 of the four-lift RGV vehicle 5. The four-lift RGV vehicle 5 moves to the working area 25, and then the second scissor-type telescopic frame 52 shrinks in sequence to place the four fork slots 15 on the working area 25 in sequence. After placement, it returns to the initial position to prepare for the next transportation; the telescopic cantilever beam truss 8 at the two bottom beam stacks 11 in the first storage area 21 or the second storage area 22 lifts eight bottom beams 16, and places four in a group on both sides of a fork slot 15 in the working area 25 twice, and then Repeat the operation, lift four bottom beams 16 respectively and place them on the other side of another fork groove 15 on the working area 25, and the top truss 6 at the top of the upper area 24 transports two pairs of four bottom side beams 17 to the working area 25 at one time, and is located on both sides of the fork groove 15 and the bottom beam 16. The long RGV car 4 moves to the bottom of the working area 25, lifts and transports each beam and groove to the welding manipulator 14. During the transportation process, the retractable truss above the non-standard bottom beam stack 12 will pre-lift the four non-standard bottom beams to the predetermined position and place them on the walking RGV car in turn, completing the entire loading process. During the loading operation, the mutual coordination of the actions of each mechanism is optimized through the PLC control system to achieve the best operating efficiency.

[0044] During the replenishment operation of each beam pile group and trough pile group, when the two bottom cross beam pile groups 11 are used up synchronously, the other two spare bottom cross beam pile groups 11 are activated, and the two empty RGV transport vehicles 3 transport the empty bottom frames of the used bottom beam pile groups to the cargo warehouse for loading the bottom beam pile groups, and then transport them to the work station for spare rotation. If the cargo warehouse is far away, two more RGV transport vehicles are needed to load them in advance for replenishment; when the non-standard bottom beam pile group is used up, the empty RGV transport vehicle waiting in advance immediately enters the work station to take away the empty bottom frames, and at the same time another fully loaded RGV transport vehicle enters the work station to replenish the non-standard bottom beam pile group; when the four bottom side beam pile groups are used up, the four spare pile groups are activated, the front-section liftable chain conveyor mechanism 7 descends to the lower area, and the four empty bottom frames are simultaneously transported to the rear-section fixed chain conveyor mechanism The lower layer of the RGV transport vehicle waits for transportation, and then the front-end liftable chain conveyor mechanism is raised to the upper work station, and the front and rear chain conveyor mechanisms are started to move the spare bottom side beam stack from the rear work station to the front work station, and then the bottom side beam stack on the waiting four fully loaded RGV transport vehicles is transported to the rear chain conveyor mechanism, of which two vehicles run at the same time. At the end of each group of transportation, the RGV transport vehicle lifting mechanism stops during the descent process and takes away the empty bottom frame on the lower layer, completing the rotation and replenishment of the bottom side beam stack; when the fork slot stack on the right side of the three-dimensional storage rack is used up, two RGV transport vehicles are used to take out the empty frame and replenish the material respectively. The entire replenishment operation process also needs to be precisely designed by the PLC control system to avoid spatial intersection of the mechanism, achieve optimal time intersection, and achieve optimal operating efficiency.

[0045] Example 2: Figure 7 As shown, the present invention provides a fully automatic container chassis loading system. The difference from Example 1 is that when loading a 40-foot container chassis, a long bottom side beam stack 18 is placed on the chain conveyor mechanism 7 of the upper area 24 to transport the long bottom side beams of the 40-foot container. The remaining structures are similar, and the chassis loading of a 40-foot container is realized.

[0046] Working principle: The loading operation of each beam and trough in the working area is carried out simultaneously with the replenishing operation of each stack. During the loading operation, the top truss 6 on the top of the gooseneck trough stack 10 lifts a gooseneck trough and transports it to the four loading platforms 53 of the four-lift RGV car 5. The four-lift RGV car 5 moves to the working area 25, and then the second scissor-type telescopic frame 52 shrinks at the same time to place a gooseneck trough at the leftmost end of the working area 25. After placement, it returns to the initial workstation to prepare for the next transportation; the telescopic cantilever beam trusses 8 at the two bottom beam stacks 11 in the first storage area 21 or the second storage area 22 each lift a group of seven bottom beams 16, and place them at intervals on the working area 25, and then repeat the operation to lift each one. Seven bottom cross beams 16 are placed on one side of the previous batch of bottom cross beams 16 in the working area 25. The top truss 6 at the top of the upper area 24 transports a pair of two long bottom side beams in the long bottom side beam stack 18 to the working area 25 at the same time, and is located on both sides of the gooseneck trough and the bottom cross beam 16. The long RGV car 4 moves to the bottom of the working area 25, rises and transports the beams and troughs to the next process, completing the entire loading process of the 40-foot container chassis. During the loading operation, the mutual coordination of the actions of each mechanism is optimally designed through the PLC control system to achieve the best operating efficiency, and a spare stack is set up, so that after the stack is loaded, the spare stack is activated synchronously and the empty stack is replenished to achieve continuous automatic loading.

[0047] Example 3: Figure 8 As shown, the present invention provides a fully automatic container chassis loading system, which is different from Example 1 and Example 2 in that, when loading a 20-foot non-standard container chassis, three groups of bottom side beam reinforcement plates 19 are placed in the lower area 23 of the first storage area 21, and the bottom cross beam group is placed in the second storage area 22. The rest of the structure is similar, which meets the requirements of chassis loading of a 20-foot non-standard container and pre-welding between the bottom side beam reinforcement plates 19.

[0048] Working principle: The loading operation of each beam and trough in the working area is carried out simultaneously with the replenishment operation of each stack. During the loading operation, the top truss 6 on the top of the fork trough stack 9 lifts two fork troughs and transports them to the two loading platforms 53 in the four-lift RGV vehicle 5. The four-lift RGV vehicle 5 moves to the working area 25, and then the second scissor-type telescopic frame 52 shrinks in sequence to place the two fork troughs at the right end of the working area 25. After placement, it returns to the initial position to prepare for the next transportation; the three groups of bottom side beam reinforcement plates 19 in the first storage area 21 and the two bottom cross beam stacks 11 in the second storage area 22 each lift two bottom side beam reinforcement plates 19 and a group of seven bottom cross beams 16. They are placed on the left and right sides of the fork slots in the work area 25, and the operation is repeated twice. The required bottom side beam reinforcement plates 19 and bottom cross beams 16 are placed on one side of the previous batch of bottom side beam reinforcement plates 19 and the other side of the fork slots in the work area 25. The top truss 6 at the top of the upper area 24 transports a pair of two bottom side beams in the bottom side beam stack 17 to the work area 25 at one time and is located on both sides of the fork slots and bottom cross beams 16. The welding robot 14 pre-welds each bottom side beam reinforcement plate 19. The long RGV car 4 moves to the bottom of the work area 25, lifts up, and transports each beam and slot to the next process, completing the entire loading of the 20-foot non-standard container chassis and the pre-welding of the bottom side beam reinforcement plates 19. During the loading operation, the mutual coordination of the actions of each mechanism is optimized through the PLC control system to achieve the best operating efficiency, and a spare stack is set up. After the stack is loaded, the spare stack is synchronously activated and the empty stack is replenished to achieve continuous automatic loading.
