Description

Technical Field

[0001] This utility model belongs to the technical field of coil handling, and more specifically, it relates to an improved track AGV handling trolley. Background Technology

[0002] In modern industrial production and logistics, the demand for automated and intelligent material handling equipment is growing. AGVs, as automated transport vehicles equipped with electromagnetic or optical automatic guidance devices, can travel along designated guide paths and have safety protection and various load transfer functions. They have been widely used in many industries. However, from the current industry perspective, traditional rail AGVs have revealed a series of problems when handling specific materials, such as coil handling.

[0003] In terms of height adjustment, early track-mounted AGV transport vehicles often lacked precise and flexible height adjustment mechanisms. Many similar devices could only achieve simple overall lifting and lowering, unable to make fine adjustments based on coils placed at different heights. This meant that during transport, a large amount of manual assistance was required to adjust the relative height between the device and the coil, resulting in low efficiency and potential safety hazards due to human error. Like some early AGVs, their simple material rack height adjustment structures could not meet the complex and diverse material handling needs, greatly limiting the scope of application and work efficiency of the equipment.

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

[0018] This utility model discloses an improved track-mounted AGV transport trolley. By incorporating a coil clamping device, the clamping force and position can be precisely controlled, ensuring stable and accurate clamping and fixing of the coil. This prevents the coil from shaking or shifting during transport, thus improving the reliability of transport.

[0049] See attached document Figure 4 A drive assembly 15 is fixedly installed on the bottom of the base plate 18. The drive assembly 15 includes a drive motor 16, which is fixedly installed on the bottom of the base plate 18. Two sets of transmission guide rods 17 are rotatably provided on the bottom of the base plate 18, and the transmission guide rods 17 and the drive motor 16 are driven by sprockets.

[0050] Specific usage method of this utility model:

[0051] First, the improved tracked AGV transport trolley is accurately placed on the cable transport rail. At this point, the drive motor 16 installed at the bottom of the device starts. The drive motor 16 drives two sets of transmission guide rods 17, which are rotated at the bottom of the base plate 18, via a sprocket drive. Because the transmission guide rods 17 are in contact with the rail, the friction generated by their rotation propels the entire device along the rail, thus moving the device towards the coil placement location. During the movement, the operator can monitor the device's speed and direction in real time through the control system to ensure the device accurately reaches the target position.

[0052] Once the equipment reaches the predetermined coil placement position, the vertical electric sliders 24 located at the four corners of the frame assembly 11 are activated. The vertical electric sliders 24 slide on the surface of the vertical slide rail 21. Since a rotation adjustment assembly, including a lifting frame 30, is fixedly installed between the four corner vertical electric sliders 24, and the lifting frame 30 is fixedly connected to the vertical electric sliders 24, the sliding of the vertical electric sliders 24 causes the lifting frame 30, the entire rotation adjustment assembly, and components such as the horizontal push assembly 33 and the coil clamping device 31 mounted on it to adjust their height together. The operator can precisely set the rising or falling distance of the vertical electric sliders 24 through the equipment's operation panel according to the actual height of the coil, ensuring that the coil transport assembly 14 can accurately reach the appropriate height position for transporting the coil.

[0053] After the height of the coil handling assembly 14 is adjusted, the rotary motor 27 installed in the equipment starts to work. The rotary motor 27 is fixedly mounted on the arc-shaped plate 26, and its output shaft meshes with the gear on the outer side of the gear plate 29. After the rotary motor 27 starts, it drives the gear plate 29 to move laterally through gear transmission. Since the gear plate 29 is fixedly connected to the primary electric slider 40, the lateral movement of the gear plate 29 drives the primary electric slider 40 to slide within the groove provided on the surface of the arc-shaped plate 26.

[0054] As the primary electric slider 40 slides, the primary guide rail 41 mounted on it extends accordingly. A secondary electric slider 42 slides on the primary guide rail 41. As the primary guide rail 41 extends, the secondary electric slider 42 slides and extends on the primary guide rail 41, thereby driving the secondary guide rail 44 to extend. The tertiary electric slider 43, which slides on the secondary guide rail 44, also extends, ultimately driving the coil clamping device 31 fixedly connected above it to extend towards the coil. During this process, the precision of the fit between each level of slider and guide rail determines the accuracy of the extension of the coil clamping device 31. The operator can observe the operation of each component through the equipment's monitoring system to ensure the smooth progress of the extension operation.

[0055] When the coil clamping device 31 extends to a position close to the coil 32, the telescopic motor 34 partially installed in the coil clamping device 31 is activated. The telescopic motor 34 is fixedly mounted on one side of the support frame 28, and its output end passes through the support frame 28 and connects to the clamping plate 35. After the telescopic motor 34 is activated, the height of the clamping plate 35 is adjusted by controlling the extension length of the output shaft. According to the size of the coil 32, the operator sets the operating parameters of the telescopic motor 34 through the operation panel, so that the clamping plate 35 rises to a height that can completely cover the coil 32.

[0056] Once the clamping plate 35 and support frame 28 have covered the coil 32, the telescopic motor 34 restarts, controlling the clamping plate 35 to descend. During the descent, the limiting guide rod 36 plays a crucial role; it is slidably mounted to the support frame 28 and fixedly connected to the clamping plate 35, ensuring the smoothness and straightness of the descent. When the clamping plate 35 descends to the appropriate position, it, together with the support frame 28, tightly clamps the coil 32. At this point, the operator can detect the clamping force through the equipment's sensor system to ensure the coil is securely clamped and will not be damaged due to excessive clamping force.

[0057] After coil 32 is clamped, the coil clamping device 31 retracts and resets. Simultaneously, the rotary motor 38, located inside the central pad 37, starts. The output shaft of the rotary motor 38 meshes with a ring gear 39 fixedly mounted on the inner side of the arc-shaped plate 26. Through this gear engagement, the rotary motor 38 drives the ring gear 39 to rotate. Since the arc-shaped plate 26 is fixedly connected to the ring gear 39, the rotation of the ring gear 39 causes the entire arc-shaped plate 26 to rotate around its connection point with the central pad 37. During rotation, the operator can set the rotation angle of the rotary motor 38 via the control panel according to the target placement position, allowing the arc-shaped plate 26 to rotate accurately to the predetermined 180-degree position, adjusting the clamped coil to a suitable placement orientation.

[0058] After the arc plate 26 rotates to the predetermined position, the rotating motor 27 extends again. Its working principle is the same as the previous extension operation; through gear transmission, it drives the gear plate 29, the primary electric slider 40, and other components, causing the coil clamping device 31 to extend again. When the coil clamping device 31 extends to the target placement position, the telescopic motor 34 starts, controlling the clamping plate 35 to rise, releasing the clamp on the coil 32, thus placing the coil.

[0059] After placement, the rotating motor 27 drives the coil clamping device 31 to retract and reset. Simultaneously, the drive motor 16 at the bottom of the equipment restarts, moving the equipment along the rail to the next coil placement location. This extension and reset operation is repeated to continuously transport the coils. Throughout the entire transport process, the equipment's automated control system closely coordinates each operational step to ensure efficient, accurate, and safe transport.
