Description
Technical Field
[0001] This utility model is specifically an AGV trolley for aluminum coil production, which relates to the field of aluminum coil production technology. Background Technology
[0002] In terms of logistics management, most aluminum processing companies use a combination of bridge cranes and forklifts to transfer aluminum ingots, coils, rolls, and saddles across regions. The entire transfer process requires manual operation, which inevitably leads to operational errors and safety issues. Currently, the industry is discussing intelligent logistics systems, which involve AGVs (Automated Guided Vehicles). While AGVs can be used to transport goods autonomously, their limited load capacity and large turning radius prevent them from accurately and tightly placing large, heavy aluminum ingots and coils within the warehouse. Therefore, there is a need to design an AGV based on intelligent logistics, suitable for transporting aluminum coils. Utility Model Content

[0020] An AGV (Automated Guided Vehicle) for aluminum coil production is disclosed, relating to the field of aluminum coil production technology. It is mainly used to solve the problem that existing AGVs have a large turning radius and cannot accurately transport aluminum coils.
[0021] See attached document Figure 1 and attached Figure 2 The AGV of this utility model mainly consists of a vehicle body 1, four steering wheels 2, a steering mechanism, and a lifting mechanism. The composition and working principle of this AGV are described in detail below.
[0022] This AGV has a square body 1, with four steering wheels 2 arranged in a square at the four corners of the body 1. To improve the AGV's load-bearing capacity and independent movement capability, and to make it suitable for transporting aluminum coils, a hydraulic station (not shown in the figure) powered by a lithium battery is installed inside the body 1. This hydraulic station provides strong power to the steering and lifting mechanisms.
[0023] See attached document Figure 3 Each steering wheel 2 consists of a steering shaft 2.1 and a pair of wheels 2.3 symmetrically arranged on both sides of the steering shaft 2.1, wherein the wheels 2.3 are driven by hub motors. The steering shaft 2.1 is vertically arranged, and a swing arm 2.2 is provided on the upper part of the steering shaft 2.1. Since the pair of wheels 2.3 are symmetrically arranged about the steering shaft 2.1, rotating the swing arm 2.2 can turn the steering wheel 2 in place. Hub motors are commonly used in electric bicycles, and are characterized by high torque, compact structure, and an integrated structure with the wheels 2.3. In this embodiment, the AGV is driven by eight hub motors, which is sufficient to meet the needs of transporting goods such as aluminum ingots, aluminum coils, and rolls.
[0024] See attached document Figure 4 and attached Figure 5 The steering mechanism mainly consists of a turntable 3, a connecting rod 4, and a hydraulic motor 6. The hydraulic motor 6 is connected to the turntable 3 and is used to drive the turntable 3 to rotate. The turntable 3 is hinged to the rotating arm 2.2 on each steering shaft 2.1 through the connecting rod 4, and is used to push the four steering wheels 2 to turn in place at the same time.
[0025] To enable the four steering wheels 2 to turn 90° in place, an arc-shaped gap is provided on part of the edge of the turntable 3. A limit post 5 is fixed on the vehicle body 1, located within the arc-shaped gap, to limit the rotation angle of the turntable 3, allowing the steering wheels 2 to rotate only 90°, changing from the forward / backward travel direction to the left / right travel direction, thus enabling the AGV to make a right-angle turn in place. In this way, the AGV can move flexibly in narrow areas and accurately place large and heavy goods such as aluminum ingots, aluminum coils, and rolls tightly within the storage area.
[0026] A lifting mechanism is mounted on the vehicle body 1 and is used for lifting and lowering goods. In this embodiment, the lifting mechanism consists of a lifting pallet 9, a pair of hydraulic cylinders 7, and four guide columns 8, wherein the four guide columns 8 are symmetrically arranged about the pair of hydraulic cylinders 7. The pair of hydraulic cylinders 7 can provide sufficient lifting force to lift aluminum ingots or coils weighing 2 tons. The function of the four guide columns 8 is to improve the stability of the lifting pallet 9 and prevent the lifting pallet 9 and the goods from tilting.
[0027] See attached document Figure 6 To facilitate production management, an electronic tag reader 10 is installed on the lifting pallet 9. The electronic tag reader 10 is used to read the information of the radio frequency electronic tag 12 on the goods 11 and transmit the information of the radio frequency electronic tag 12 to the production management system via a wireless local area network. Depending on the situation, the production management system can also write new information into the radio frequency electronic tag 12 through the electronic tag reader 10 to update the production status information of the goods 11.
[0028] In summary, the AGV of this invention has a large load-bearing capacity, runs smoothly, and can make right-angle turns on the spot. It is very suitable for moving flexibly in narrow areas, and is especially suitable for transporting large and heavy goods such as aluminum ingots, aluminum coils, and rolling mill rolls.
[0029] It is worth noting that the content not described in detail in the above embodiments is prior art. It is also worth noting that any additions, subtractions, substitutions, and improvements made by those skilled in the art based on the structure and principles of this utility model should be included within the protection scope of this utility model.
