Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cargo loading and unloading, and in particular to an automated clamping and loading / unloading machine for bulk cargo. Background Technology
[0002] In logistics transportation, it is often necessary to load and unload bulk goods. Currently, there are two main methods for loading and unloading bulk goods: one is using forklifts, where the forks of the forklift are inserted into pallets, and large cargo boxes are placed on the pallets. The forks are then used to load and unload the pallets and large cargo boxes. The other is hoisting, which involves tying ropes to the goods and using a crane to lift the goods by the ropes. Workers can choose between forklifts or cranes to load and unload goods as needed. However, both forklifts and cranes only have the function of hoisting or forking, which has high limitations. Material warehouses need to prepare both forklifts and cranes to meet daily needs, which occupies a large area and is inconvenient to use. Therefore, there is a need for a bulk goods loading and unloading machine that can perform both hoisting and forking functions. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides an automated clamping and unloading machine for bulk goods that integrates a hoisting mechanism and a forklift mechanism, which can not only hoist goods but also forklift goods, has a small footprint, is easy to use, and is highly practical.
[0004] This utility model relates to an automated bulk cargo handling and loading / unloading machine, comprising an electric mobile cart, a rotating mechanism, a fixed frame, a lifting mechanism, a forklift mechanism, and a hoisting mechanism. The fixed frame is mounted on the electric mobile cart via the rotating mechanism, which rotates the fixed frame. The lifting mechanism is mounted on the fixed frame and has lifting functions. The forklift mechanism is mounted on the left side of the lifting mechanism, and the hoisting mechanism is mounted on the right side of the fixed frame. When loading and unloading bulk cargo, if forklifting is required, the forklift mechanism is positioned on the left side of the fixed frame. Then, the electric mobile cart is moved, allowing the forklift mechanism to insert into the pallet at the bottom of the cargo. The lifting mechanism then raises the pallet, allowing the cargo to rise and move. When hoisting is required, the rotating mechanism is activated, causing the fixed frame to rotate. This moves the hoisting mechanism from the right side of the fixed frame to the left side, allowing the cargo to be hoisted. By combining the hoisting and forklift mechanisms, this machine can handle both hoisting and forklifting of cargo, has a small footprint, is easy to use, and is highly practical.
[0005] Preferably, the rotating mechanism includes a support shaft, bevel gear A, bevel gear B, a drive shaft, a mounting plate, and a stepper motor. The support shaft is rotatably mounted on the electric mobile cart, and the fixed frame is fixedly mounted on the upper end of the support shaft. Bevel gear A is fixedly mounted on the support shaft, and bevel gear A meshes with bevel gear B. Bevel gear B is fixedly mounted on the drive shaft, and the drive shaft is rotatably mounted on the mounting plate. The input end of the drive shaft is connected to the stepper motor. Both the mounting plate and the stepper motor are fixedly mounted on the electric mobile cart. When it is necessary to rotate the fixed frame, the stepper motor is turned on. The stepper motor drives bevel gear B to rotate bevel gear A through the drive shaft, thereby causing the support shaft to rotate the fixed frame. This facilitates the rotation of the fixed frame and improves convenience.
[0006] Preferably, the lifting mechanism includes a hydraulic cylinder, a push rod, and a lifting plate. The hydraulic cylinder is fixedly installed on the upper end of the fixed frame, the upper end of the push rod is slidably installed on the fixed frame, and the upper end of the push rod is connected to the output end of the hydraulic cylinder. The lifting plate is slidably installed on the fixed frame, and the lifting plate is fixedly installed on the lower end of the push rod. The forklift mechanism is installed on the left end of the lifting plate. When the forklift mechanism is inserted into the pallet at the bottom of the goods, the hydraulic cylinder is opened. The hydraulic cylinder causes the lifting plate to rise and fall through the push rod, and the lifting plate causes the goods to rise and fall through the forklift mechanism, which facilitates the adjustment of the goods height.
[0007] Preferably, the forklift mechanism includes a fixed plate, forks, and a clamping mechanism. The fixed plate is fixedly installed on the left end of the lifting plate, the forks are fixedly installed on the fixed plate, and the clamping mechanism is provided on the fixed plate. The clamping mechanism has the function of clamping and fixing. When it is necessary to forklift the goods, the forks are inserted into the pallet at the bottom of the goods, and then the goods are clamped and fixed by the clamping mechanism. After that, the goods can be moved. This facilitates the forklift transportation of goods.
[0008] Preferably, the clamping mechanism includes a servo motor, a lead screw, and two sets of clamping plates. The servo motor is fixedly mounted on a fixed plate, and the lead screw is rotatably mounted on the fixed plate. The front and rear parts of the lead screw are respectively provided with external threads in opposite directions. The two sets of clamping plates are screwed to the front and rear parts of the lead screw, and both sets of clamping plates are slidably mounted on the fixed plate. The forks are located below the fixed plate. When the forks are inserted into the pallet at the bottom of the goods, the servo motor is turned on, and the servo motor drives the lead screw to rotate, causing the two sets of clamping plates to move closer to each other and clamp the goods in place. This improves the stability of the goods during forklift transport.
[0009] Preferably, the hoisting mechanism includes a fixed frame and a winch. The fixed frame is fixedly installed on the right end of the fixed frame, and the winch is fixedly installed on the upper end of the fixed frame. A rope is provided on the winch, and a hook is provided at the lower end of the rope. The hook is fixedly installed at the lower end of the rope. When it is necessary to hoist the goods, the rotating mechanism is opened to rotate the fixed frame, causing the fixed frame on the right side of the fixed frame to rotate to the left side of the fixed frame. Then, the winch is opened to unwind the rope, causing the lower end of the rope and the hook to descend. The hook then hooks the lifting ring on the goods, and the winch rewinds the rope, causing the hook to lift the goods, thus facilitating the hoisting of the goods.
[0010] Preferably, it also includes a counterweight, which is fixedly installed on the right side of the upper part of the electric mobile vehicle; through the above arrangement, the forces on the left and right sides of the electric mobile vehicle are more balanced, thus improving stability.
[0011] Compared with the prior art, the advantages of this utility model are: it combines the hoisting mechanism and the forklift mechanism, which can not only hoist goods, but also forklift goods, occupy a small area, is convenient to use, and has high practicality. Attached Figure Description

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.
[0020] Example 1
[0021] like Figures 1 to 6 This utility model relates to an automated bulk cargo handling and loading machine, comprising an electric mobile cart 1, a rotating mechanism, a fixed frame 2, a lifting mechanism, a forklift mechanism, and a hoisting mechanism. The fixed frame 2 is mounted on the electric mobile cart 1 via the rotating mechanism, which rotates the fixed frame 2. The lifting mechanism is mounted on the fixed frame 2 and has a lifting function. The forklift mechanism is mounted on the left side of the lifting mechanism, and the hoisting mechanism is mounted on the right side of the fixed frame 2. When loading and unloading bulk cargo, if forklift transport is required, the forklift mechanism is positioned on the left side of the fixed frame 2. Then, the electric mobile vehicle 1 is moved so that the forklift mechanism is inserted into the pallet at the bottom of the goods. Then, the lifting mechanism is used to raise the pallet, and then the goods are raised and moved. When it is necessary to lift the goods, the rotating mechanism is opened so that the fixed frame 2 is rotated, and the lifting mechanism on the right side of the fixed frame 2 is rotated to the left side of the fixed frame 2. Then the goods can be lifted by the lifting mechanism. It combines the lifting mechanism and the forklift mechanism, which can not only lift the goods, but also forklift the goods. It has a small footprint, is easy to use, and is highly practical.
[0022] like Figure 1 and Figure 6 The rotating mechanism includes a support shaft 4, bevel gear A5, bevel gear B6, a drive shaft 7, a mounting plate 8, and a stepper motor 9. The support shaft 4 is rotatably mounted on the electric mobile cart 1, and the fixed frame 2 is fixedly mounted on the upper end of the support shaft 4. Bevel gear A5 is fixedly mounted on the support shaft 4 and meshes with bevel gear B6. Bevel gear B6 is fixedly mounted on the drive shaft 7, and the drive shaft 7 is rotatably mounted on the mounting plate 8. The input end of the drive shaft 7 is connected to the stepper motor 9. Both the mounting plate 8 and the stepper motor 9 are fixedly mounted on the electric mobile cart 1. When it is necessary to rotate the fixed frame 2, the stepper motor 9 is turned on. The stepper motor 9 drives the bevel gear A5 through the drive shaft 7, thereby causing the support shaft 4 to rotate the fixed frame 2. This facilitates the rotation of the fixed frame 2 and improves convenience.
[0023] like Figure 3The lifting mechanism includes a hydraulic cylinder 10, a push rod 11, and a lifting plate 12. The hydraulic cylinder 10 is fixedly installed on the upper end of the fixed frame 2. The upper end of the push rod 11 is slidably installed on the fixed frame 2, and the upper end of the push rod 11 is connected to the output end of the hydraulic cylinder 10. The lifting plate 12 is slidably installed on the fixed frame 2 and fixedly installed on the lower end of the push rod 11. The forklift mechanism is installed on the left end of the lifting plate 12. When the forklift mechanism is inserted into the pallet at the bottom of the goods, the hydraulic cylinder 10 is opened. The hydraulic cylinder 10 raises and lowers the lifting plate 12 through the push rod 11. The lifting plate 12 raises and lowers the goods through the forklift mechanism, which facilitates the adjustment of the goods height.
[0024] like Figure 3 and Figure 4 The forklift mechanism includes a fixed plate 3, forks 13, and a clamping mechanism. The fixed plate 3 is fixedly installed on the left end of the lifting plate 12, and the forks 13 are fixedly installed on the fixed plate 3. The clamping mechanism is provided on the fixed plate 3, and the clamping mechanism has the function of clamping and fixing. When it is necessary to forklift the goods, the forks 13 are inserted into the pallet at the bottom of the goods, and then the goods are clamped and fixed by the clamping mechanism. After that, the goods can be moved. This facilitates the forklift transportation of goods.
[0025] like Figure 4 The clamping mechanism includes a servo motor 14, a lead screw 15, and two sets of clamping plates 16. The servo motor 14 is fixedly mounted on the fixed plate 3, and the lead screw 15 is rotatably mounted on the fixed plate 3. The front and rear parts of the lead screw 15 are respectively provided with external threads in opposite directions. The two sets of clamping plates 16 are screwed to the front and rear parts of the lead screw 15, respectively. Both sets of clamping plates 16 are slidably mounted on the fixed plate 3. The forks 13 are located below the fixed plate 3. When the forks 13 are inserted into the pallet at the bottom of the goods, the servo motor 14 is turned on. The servo motor 14 drives the lead screw 15 to rotate, causing the two sets of clamping plates 16 to move closer to each other and clamp the goods in place. This improves the stability of the goods during the forklift transportation process.
[0026] like Figure 1 and Figure 5 The hoisting mechanism includes a fixed frame 17 and a winch 18. The fixed frame 17 is fixedly installed on the right end of the fixed frame 2, and the winch 18 is fixedly installed on the upper end of the fixed frame 17.

When it is necessary to hoist the goods, the rotating mechanism is opened to rotate the fixed frame 2, so that the fixed frame 17 on the right side of the fixed frame 2 rotates to the left side of the fixed frame 2. Then, the winch 18 is opened to unwind the rope 19, thereby lowering the lower end of the rope 19 and the hook 20. Then, the hook 20 hooks the lifting ring on the goods, and then the winch 18 winds up the rope 19, so that the hook 20 lifts the goods, which facilitates the hoisting of the goods.
