DETAILED DESCRIPTION

[0019] like Figure 1 and Figure 2 As shown, the terminal automated rapid loading and unloading control system comprises a ground rail 1, which is arranged between a cargo ship docked at the terminal and a truck docked on the ground. Laser rangefinders 29 are also arranged at both ends of the ground rail 1, and the laser rangefinders 29 are used to detect the distance between the truck and the ground rail 1. A groove is arranged in the ground rail 1, and there are two parallel grooves. Slide piles 2 are arranged in the grooves. A hydraulic cylinder 10 is also arranged above one end of the ground rail 1, and the end of the hydraulic cylinder 10 is connected to the slide pile 2. A loading and unloading platform 3 is fixedly connected above the slide pile 2. There are two loading and unloading platforms 3 and they are parallel. The loading and unloading platforms 3 are placed vertically to the ground rail 1, and the two ends of the loading and unloading platforms 3 extend above the cargo ship and the truck respectively. A fixing block 4 is fixedly connected to the upper surface of the loading and unloading platform 3.

[0020] The fixed block 4 is provided with grooves on both sides, and a sliding arm is provided above the fixed block 4. The sliding arm includes an upper sliding arm 5 and a lower sliding arm 6. The upper sliding arm 5 and the lower sliding arm 6 are arched, and the height of the upper sliding arm 5 is higher than that of the lower sliding arm 6. The two ends below the lower sliding arm 6 are located in the opposite grooves of the fixed block 4, and the two ends below the upper sliding arm 5 are located in the opposite grooves of the fixed block 4. The height of the upper sliding arm 5 and the lower sliding arm 6 can move back and forth in the groove of the fixed block 4 without interfering with each other. A chain conveyor belt 7 is also provided on the upper surface of one of the loading and unloading platforms 3, and the fixed block 4 on this side is located inside the chain conveyor belt 7. A lower connecting block 8 is fixedly connected between one side of the chain conveyor belt 7 and the lower sliding arm 6, and an upper connecting block 9 is fixedly connected between the other side of the chain conveyor belt 7 and the upper sliding arm 5.

[0021] When the truck is docked at the side of the cargo ship at the dock, the laser rangefinder 29 detects the distance between the truck and the ground rail 1, and the hydraulic cylinder 10 starts to extend, driving the sliding pile 2 to move toward one end of the truck cargo compartment, so that the upper sliding arm 5 and the lower sliding arm 6 are located above one end of the truck cargo compartment.

[0022] like Figure 2 and Figure 3 As shown, a transport structure 27 is further provided under the slide arm, and the transport structure 27 includes a slide track 30. The slide track 30 is composed of two parallel tracks and is fixedly connected to the lower surface of the slide arm. A turntable 11 is also provided between the slide tracks 30. The turntable 11 is located on the lower surface of the slide arm and can rotate on the lower surface of the slide arm. A driving plate 12 is fixedly connected to the surface of the turntable 11, and driving rotating shafts 13 are provided at both ends of the driving plate 12.

[0023] The driving plate 12 is also provided with a carrier plate 14 on both sides. The carrier plate 14 is mounted between the two sliding rails 30 and can move back and forth in the sliding rails 30. A translation rotation axis 17 is also provided on the central surface of the carrier plate 14. The driving rotation axis 13 and the translation rotation axis 17 are connected by a connecting rod. Visual cameras 31 are also fixedly connected to both sides of the carrier plate 14. The visual camera 31 is used to capture the position image of the metal plate under the carrier plate 14 and feed the metal plate position image back to the control system.

[0024] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, lifting components 15 are also provided at both ends of the loading plate 14. The lifting components 15 include a spiral groove 18 and a separation box 32, and a transfer groove 21 is connected between the two. There are two opposite spiral grooves 18, and a chain 19 is provided in the spiral groove 18. The surface of the chain 19 is distributed with bite blocks 20, and the end of the bite block 20 is a semicircular structure.

[0025] The split box 32 is provided with a lifting gear 23 and a pressing roller 26. The lifting gear 23 and the pressing roller 26 each have a group and are relatively distributed. The chain 19 passes through the middle, and the bite blocks 20 on the surface of the chain 19 are staggered. The lifting gear 23 and the pressing roller 26 can rotate in the split box 32. The teeth of the lifting gear 23 extend into the chain 19. The surface of the lifting gear 23 is also provided with a first bevel gear 24. The surface of the first bevel gear 24 is also provided with a second bevel gear 25. The two are meshed with each other through the teeth. The side of the second bevel gear 25 is also fixedly connected with a lifting motor 22. The lifting motor 22 is fixedly installed on the inner wall of the split box 32. The lifting motor 22 is used for the rotation of the second bevel gear 25. The rotation of the second bevel gear 25 drives the first bevel gear 24 and the lifting gear 23 to rotate. 23 rotates to drive the chain 19 to move up and down. When the chain 19 moves downward, it passes through the transfer groove 21 and the relative surface of the pressing roller 26. The pressing roller 26 squeezes and squeezes the interlaced bite blocks 20 together, so that the two chains 19 are combined into one. When the chain 19 moves upward, it passes through the pressing roller 26 and the transfer groove 21, it is split into two by the transfer groove 21, and the bite blocks 20 are split from each other. So the two chains 19 are separated and curled in the spiral groove 18 for storage, which saves space and can arbitrarily control the size of the chain 19 descending. An electromagnetic plate 16 is provided under the lifting component 15. The electromagnetic plate 16 is fixedly connected to the ends of the two relative chains 19. An ultrasonic sensor 28 is also provided on the surface of the electromagnetic plate 16. The ultrasonic sensor 28 is used to detect the size of the electromagnetic plate 16 from the metal plate.

[0026] When the upper sliding arm 5 and the lower sliding arm 6 are adjusted into place, the chain conveyor belt 7 starts. Since the lower connecting block 8 and the upper connecting block 9 are located on both sides of the chain conveyor belt 7, the upper sliding arm 5 and the lower sliding arm 6 move in opposite directions along the grooves on both sides of the fixed block 4, that is, they move above the truck and the cargo ship respectively. When the visual camera 31 in the sliding arm above the truck detects the position and length of the metal plate inside it, the chain conveyor belt 7 stops, and the turntable 11 and the driving plate 12 start to rotate. By driving the connecting rod between the rotating shaft 13 and the translating rotating shaft 17, the loading plate 14 is driven to move on the surface of the sliding track 30, so that the distance between the electromagnetic plates 16 is adapted to the length of the metal plate, and then the lifting motor 22 is started to lower the electromagnetic plate 16 to the top of the metal plate through the chain 19. When the ultrasonic sensor 28 detects that the electromagnetic plate 16 reaches the surface of the metal plate, the lifting motor 22 stops, the electromagnetic plate 16 is energized and magnetized, and the metal plate below is adsorbed on the lower surface of the electromagnetic plate 16, and then the lifting motor 22 starts to rotate in the opposite direction to lift and reset the electromagnetic plate 16 to prevent interference when the upper sliding arm 5 and the lower sliding arm 6 meet in the middle. The chain conveyor belt 7 starts to rotate in the opposite direction to transport the metal plate to the top of the cargo ship. At this time, the other sliding arm is just above the metal plate of the truck. The lifting motor 22 drives the chain 19 to rise and fall, and the metal plate above the cargo ship is placed into the cargo ship. At the same time, the electromagnetic plate 16 above the truck re-adsorbs a new metal plate, and this is repeated until the metal plate in the truck is completely transported to the cargo ship.

[0027] like Figure 7 As shown, the terminal automated rapid loading and unloading control system also includes a central controller, which is connected to an input part and an output part. The central controller is used to receive data detected by the input part and send operating instructions to the output part to realize the automated operation of the terminal automated rapid loading and unloading control system. The central controller is also connected to an operating screen, which is used to display the operating status of the terminal automated rapid loading and unloading control system.

[0028] The input part includes an ultrasonic sensor, a laser rangefinder and a visual camera, and is used to detect the operating data within the automatic rapid loading and unloading control system of this terminal. The output part includes a chain conveyor belt, a hydraulic cylinder, a turntable, an electromagnetic plate and a lifting motor. The central controller sends an operating instruction to the output part through the operating data detected by the input part to realize the automatic operation of the automatic rapid loading and unloading control system of this terminal.
