Description

Technical Field

[0001] This utility model belongs to the technical field of AGV carts, and more specifically, it relates to an AGV transport cart with optimized usage effect. Background Technology

[0002] In industrial production, especially in scenarios involving coil frame handling, the application of automated material handling equipment is becoming increasingly widespread. With the expansion of production scale and the increasing demands for production efficiency, traditional handling methods are gradually becoming insufficient in terms of efficiency, accuracy, and safety. AGV (Automated Guided Vehicle) material handling equipment has emerged as a solution, capable of automatically traveling along preset paths to achieve efficient material handling, reduce manual intervention, and improve the stability and accuracy of the production process.

[0003] When handling coil frames of different specifications, it is essential to ensure that the clamping components are precisely aligned with the central axis of the coil frame and provide a stable and appropriate clamping force. Insufficient clamping precision may cause the coil frame to shift or even fall during handling; inappropriate clamping force, if too large, will damage the coil frame, while if too small, will compromise handling safety. During movement, the AGV (Automated Guided Vehicle) must maintain its balance to avoid accidents such as tipping over due to an unstable center of gravity or uneven load distribution. Especially when handling heavy coil frames, ensuring balanced movement through reasonable structural design and auxiliary devices is a crucial issue that needs to be addressed.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an AGV transport vehicle with optimized performance. Utility Model Content

By incorporating an extension locking assembly, the limiting guide rod in the extension locking assembly slides within the limiting groove.

[0051] Preferred options are shown in the appendix. Figure 2 and appendix Figure 5 A display screen 12 is fixedly installed on the outside of the housing 11, and a control button 13 is provided on the outside of the display screen 12. A coil frame 16 is clamped on the inside of the housing 11.

[0052] Specific usage method of this utility model:

[0053] The operator presses the control button 13 on the outside of the housing 11, activating the internal circuitry. After a self-test, the drive motor 18 starts. Its stator windings are energized, generating a magnetic field that drives the rotor to rotate, causing the drive wheel 17 to rotate around its axis via a coupling. The surface material of the drive wheel 17 has high friction, allowing it to propel the equipment forward or backward using static friction. Simultaneously, the universal auxiliary wheels 19 on both sides of the drive wheel 17, relying on a flexible universal joint steering structure, automatically adjust their angles to distribute the equipment's weight, ensuring the equipment moves balanced to the designated position.

[0054] After the equipment is in place, operate control button 13 again to send a running command to the regulating motor. The regulating motor starts, and the electromagnetic coil generates a magnetic field to drive the rotor to rotate. The controller precisely adjusts the motor speed and direction according to the command. The sprocket on the output shaft of the regulating motor drives the chain, causing the third gear to rotate, which in turn drives the first and second gears meshing with it to rotate synchronously. The chain and gears of the gravity adjustment component 27 work together to pull the counterweight 31 up and down, causing the telescopic clamping component 26 to move along the slide rail. The operator observes the display screen 12 and adjusts the telescopic clamping component 26 to the bottom directly opposite the central axis of the coil frame 16.

[0055] After the telescopic clamping assembly 26 is in position, press the control button 13 to start the rotating motor 33. The stator winding of the rotating motor 33 is energized, and the rotor rotates at high speed. The transmission gear at its output end meshes with the gear plate on the fixed block 38, causing the fixed block 38 to slide along the guide rail. The extension locking assembly 37 moves accordingly, and the limit guide rod 40 ensures stable movement within the limit groove 41. When the front protective block 43 of the telescopic clamping assembly 26 extends into the central shaft of the coil frame 16, the equipment enters the locking stage.

[0056] After the front protective block 43 extends, the extension rod 42 continues to slide. Its inclined surface contacts the inclined block 47, and under the force of the inclined block, it slides to both sides, compressing the second spring 45. At the same time, the first spring 44 is also compressed, and the extension rod 42 presses tightly against the inner wall of the central shaft of the coil frame 16, achieving locking. When the telescopic clamping assembly 26 continues to move, the sliding distance of the extension rod 42 is changed by the fixing block 38, adjusting the spring compression and precisely adjusting the clamping force according to Hooke's Law. The operator adjusts the rotating motor 33 through the control button 13 to meet the clamping requirements of different coil frames.
