Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, in particular to an automated aluminum stack transportation forklift. Background Art

[0002] An AGV forklift includes a pallet forklift type AGV, a wide-foot stacking forklift AGV, a narrow stacking forklift AGV, and a footless stacking forklift AGV, which are used for the logistics turnover of stacking palletized goods. It is composed of a hydraulic lifting system, a differential drive system, a PLC control system, a guiding system, a communication system, a warning system, an operating system, and a power supply. It is a programmable wirelessly scheduled automatic guided vehicle integrating hydraulic lifting and PLC control;

[0003] AGV is the abbreviation of (Automated Guided Vehicle), also known as an automatic guided transport vehicle or an automatic guided handling vehicle. The AGV forklift can be used for handling and stacking work with relatively high risks and can save labor costs;

[0004] The AGV forklift is very suitable for serving the casting production of aluminum ingots. After casting, the aluminum ingots are grabbed by a stacker and stacked into an aluminum stack, and then the aluminum stack is transported to a cooling workshop for centralized cooling by the AGV forklift. However, during the transportation process of the aluminum stack, due to the high temperature, there are safety hazards during the operation. During the process of the forklift lifting, braking, turning, and placing the aluminum stack, the aluminum ingots on the aluminum stack will shake, making the aluminum stack unstable and posing a safety hazard of aluminum ingot dropping. Moreover, the fork part of the existing AGV forklift is open, without a protective and fixing structure, so the safety performance and stability are poor during the transportation of the aluminum stack, and the aluminum stack is prone to becoming loose and does not have the function of preventing aluminum ingots from dropping.

[0033] Embodiment: Refer to Figures 1-4 An automated aluminum stack transportation forklift as shown, which includes two symmetrically arranged protective frames 5 and a chassis housing 1. Two bottom plates 2 are fixed to the bottom of the chassis housing 1, and a gantry 3 is slidably fitted on the upper surface of the bottom plate 2. A lifting plate 4 is slidably fitted on one side of the gantry 3. Two forks 6 are fixed to the bottom of one side surface of the lifting plate 4, and a second electric push rod 17 is fixedly penetrated through the top of the lifting plate 4. The top end of the second electric push rod 17 is fixed with an adjusting plate 11. Two second chutes 18 are opened on one side of the adjusting plate 11, and a threaded lead screw 19 is rotatably connected in the second chute 18;

[0034] A second slider 24 is fixed to one side of the protective frame 5. A plurality of groups of slide rods 21 are slidably penetrated through the protective frame 5. One end of each group of slide rods 21 is fixed with a pressing plate 22. A group of springs 23 are fixed between the pressing plate 22 and the inner side surface of the protective frame 5. The spring 23 is wound around the outside of the slide rod 21. The pressing plate 22 includes a pressing top plate and pressing side plates. Arc-shaped parts are provided at both ends of the pressing side plates. The second slider 24 is slidably fitted in the second chute 18. Both ends of the threaded lead screw 19 respectively penetrate through the two second sliders 24 and are threadedly connected to the two second sliders 24;

[0035] A plurality of first sliders 13 are slidably fitted on the forks 6. One end of each of the plurality of first sliders 13 is fixed with a cross plate 14. A group of first electric push rods 15 are embedded and fixed on the forks 6. The output end of the first electric push rod 15 is fixedly connected to the cross plate 14;

[0036] A plurality of first chutes 12 are opened on the forks 6. The first sliders 13 are slidably fitted in the first chutes 12. The upper surfaces of the first sliders 13 and the cross plate 14 are on the same horizontal plane as the upper surface of the forks 6. The two forks 6 are symmetrically arranged relative to the lifting plate 4.

[0037] The chassis housing 1 is the control box of the AGV forklift. When using this automated aluminum stack transport forklift, the chassis housing 1 can control the mast 3 to horizontally traverse along the bottom plate 2. The mast 3 can control the lifting plate 4 to vertically lift and lower. During the process of lifting the bottom tray of the aluminum stack by the forklift forks 6, when the forklift forks 6 penetrate to the bottom of the tray, at this time the aluminum stack is located on both sides of the two protective frames 5. Control the threaded screw rod 19 to start. Driven by the threaded screw rod 19, the two second sliders 24 approach each other in the second chute 18, thereby driving the two protective frames 5 to approach each other. The pressing side plates initially squeeze the two side surfaces of the aluminum stack from both sides. Subsequently, the mast 3 controls the lifting plate 4 to vertically rise, so that the forklift forks 6 can lift the pallet at the bottom of the aluminum stack. During this process, there will be side slip between the pressing plate 22 and the aluminum stack. After the aluminum stack is lifted, the second electric push rod 17 starts and drives the adjusting plate 11 to vertically move downward. The two protective frames 5 follow and descend, so that the pressing top plate presses down on the top of the aluminum stack. The pressing plate 22 will slide down along the aluminum stack again. Subsequently, control the threaded screw rod 19 to rotate again. The threaded screw rod 19 drives the two protective frames 5 to approach each other again. The pressing side plates squeeze the two side surfaces of the aluminum stack from both sides again. The spring 23 is compressed. The sliding rod 21 slides through the protective frame 5. The aluminum ingots on the aluminum stack are squeezed through the pressing plate 22, so that the aluminum stack is reinforced, avoiding the aluminum stack from falling due to shaking during transportation, and ensuring the stable transfer of the aluminum stack;

[0038] When the size of the pallet of the aluminum stack is large, start the first electric push rod 15. Push the cross plate 14 to move outward through the first electric push rod 15, driving the first slider 13 to slide outward, expanding the supporting area of the forklift forks 6 for the bottom pallet of the aluminum stack, improving the stability when the forklift forks 6 lift the aluminum stack, and being able to adapt to pallets of different sizes;

[0039] During the process of placing the aluminum stack on the shelf, first control the second electric push rod 17 and the threaded screw rod 19 to start, so that the protective frame 5 moves back to the initial position, and the protective frame 5 no longer contacts the outside of the aluminum stack. Subsequently, the chassis housing 1 controls the forklift forks 6 to move, so that the pallet descends onto the shelf, and then the forklift forks 6 are withdrawn from the pallet, thus completing the transfer and transportation of the aluminum stack.

[0040] In order to control the rotation of the threaded lead screw 19 so that the threaded lead screw 19 can control the protective frames 5 to move closer to or away from each other, in this embodiment, the threaded lead screw 19 is provided with threads with opposite helix directions. A set of guide rods 16 are fixed to the lower surface of the adjusting plate 11. The bottom ends of the guide rods 16 slidably penetrate through the lifting plate 4. One end of the adjusting plate 11 is fixedly installed with a servo motor 20 through a bracket. The output end of the servo motor 20 is fixedly connected to one end of the threaded lead screw 19 through a coupling. The servo motor 20 can drive the threaded lead screw 19 to rotate stably. The threads with opposite helix directions on the threaded lead screw 19 are respectively adapted to the two second sliders 24. The threaded lead screw 19 can drive the two second sliders 24 to move synchronously towards or away from each other, realizing the control of the two protective frames 5. The arrangement of the guide rods 16 enables the adjusting plate 11 to move vertically up and down.

[0041] In order to control the gantry 3 to move horizontally along the bottom plate 2, in this embodiment, rollers are provided at the bottoms of the chassis housing 1 and the bottom plate 2, and the forklift is driven to move by the rollers. And a second hydraulic cylinder 28 is fixedly embedded at the bottom of one side surface of the chassis housing 1. The output end of the second hydraulic cylinder 28 is fixedly connected to the bottom of the gantry 3. A third chute 25 is formed on the upper surface of the bottom plate 2. Two third sliders 27 are fixed to the bottom of the gantry 3. The third sliders 27 are slidably fitted inside the third chute 25. A limiting rod 26 is fixed to the upper surface of the bottom plate 2. The bottom of the gantry 3 is slidably sleeved on the limiting rod 26. By starting the second hydraulic cylinder 28, the gantry 3 can be driven to move horizontally. The sliding fit of the third chute 25 and the third sliders 27 enables the gantry 3 to move horizontally along the bottom plate 2. The arrangement of the limiting rod 26 improves the structural strength of the gantry 3.

[0042] In order to enable the gantry 3 to control the vertical lifting of the lifting plate 4, in this embodiment, a first hydraulic cylinder 7 is fixedly installed at the inner bottom of the gantry 3. A top rod 8 is fixed to the top end of the first hydraulic cylinder 7. Both ends of the top rod 8 are rotatably connected to a sprocket 9. A chain 10 is sleeved on the sprocket 9. One end of the chain 10 is fixedly connected to the inner bottom surface of the gantry 3, and the other end of the chain 10 is fixedly connected to the back surface of the lifting plate 4. A slide rail is fixed to one side surface of the gantry 3. A track groove is provided on one side of the lifting plate 4. The slide rail is slidably fitted in the track groove. By starting the first hydraulic cylinder 7, the top rod 8 and the sprocket 9 can be pushed to rise vertically. During the rising process of the sprocket 9, the sprocket 9 will rotate and drive the chain 10. The lifting plate 4 can be lifted by the chain 10, realizing the control of the lifting of the lifting plate 4.
