Description

Technical Field

[0001] The utility model belongs to the technical field of tractors, and particularly relates to an automatic unhooking device and an AGV tractor. Background Art

[0002] With the booming development of the logistics industry and the rapid improvement of social productivity, the demand for efficient and flexible transportation equipment is growing. In modern warehousing and logistics systems, automated guided vehicles (AGVs), especially AGV tractors, are important transportation tools and play a vital role. With their highly automated features, such as the ability to autonomously navigate to designated locations without a driver, AGV tractors not only effectively free up human resources but also improve operational efficiency and accuracy. However, while current AGV tractors can achieve unmanned transportation from the starting point to the end point, they still rely on manual uncoupling operations when unloading goods after arriving at the destination, which to some extent limits the overall automation level of logistics operations.

[0003] Therefore, it is crucial to design a device that can automatically complete the uncoupling work. This device will allow the AGV tractor to independently complete the loading and unloading tasks of goods without human intervention, thus realizing true unmanned operation.

[0004] The automatic uncoupling device will not only significantly enhance the application value of AGV tractors, but will also provide a powerful impetus for the intelligent transformation of the entire logistics industry. It will not only help reduce human errors and operating costs, but also enhance the competitiveness of enterprises by accelerating cargo turnover. Utility Model Content

[0005] In view of all or part of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide an automatic uncoupling device and an AGV tractor, which can realize automatic uncoupling of goods without human intervention when the AGV tractor is operating, thereby reducing labor costs, reducing human errors, improving the level of automation, and thus enhancing the competitiveness of the enterprise.

[0006] In order to achieve the purpose of the above utility model, the utility model provides the following technical solutions:

[0007] An automatic uncoupling device includes a bracket assembly, a pull pin, a drive assembly for moving the pull pin up and down, and a sensor assembly for sensing the pull pin's movement. The coordinated operation of these components enables fully automatic uncoupling, freeing up manpower, reducing labor costs, and improving automation.

[0008] The sensor assembly includes a support plate, two inductive switches positioned vertically on either side of the support plate, one above and one below, and a stop pin on the pull bolt. The stop pin engages the inductive switches as it moves up and down with the pull bolt. The inductive switches precisely detect the position changes of the stop pin, ensuring that each movement of the pull bolt reaches the desired position, thereby enabling precise control of the unhooking process.

[0009] Limit plates are arranged on both sides of the support plate, and limit slots are provided on the limit plates for the limit pin to move up and down. The limit slots can ensure that the limit pin moves up and down within a predetermined path, avoiding lateral deviation or swinging, and ensuring that the induction switch can be accurately triggered.

[0010] The automatic uncoupling device also includes a signal component for receiving and transmitting signals to cause the drive component to move. The signal component ensures that external instructions are accurately transmitted to the automatic uncoupling device, causing the drive component to move according to the instructions, ensuring the correct processing and transmission of signals.

[0011] The bracket assembly includes a vertical plate and a first through plate, a second through plate, and a third through plate fixedly connected to the vertical plate and arranged parallel to each other. The fixed connection between the through plate and the vertical plate improves the overall stability of the automatic unhooking device and is more reliable.

[0012] The first, second, and third through-plates are provided with vertically extending through-holes at the same parallel positions, allowing the pull bolts to move up and down. The through-holes provide a fixed installation path for the pull bolts, making them easier to align and adjust during installation and removal, simplifying the installation and maintenance process and reducing operational difficulty.

[0013] The drive assembly is mechanically connected to the first through-plate. Mechanical connection refers to the technology of physically fastening two or more components together. It has many advantages, such as the ability to withstand high loads, easy installation and removal, low cost, compatibility with various materials, and improved stability.

[0014] The drive assembly includes a guide sleeve, within which is housed an electric push rod capable of vertical movement. The guide sleeve is mechanically connected to the first through-plate, and the top of the electric push rod is connected to the top of the pull bolt. Mechanical connections offer numerous advantages, including the ability to withstand high loads, ease of installation and removal, low cost, compatibility with various materials, and improved stability.

[0015] The top of the electric push rod is mechanically connected to the top of the traction bolt via a connecting rod plate. The plate-shaped connection increases the contact area and thus improves the stability of the connection.

[0016] An AGV tractor is provided with an automatic unhooking device, which is mechanically connected to the AGV body via a vertical plate of the bracket assembly. The mechanical connection between the vertical plate and the body improves stability while not affecting the operation of other components.

[0017] The beneficial effects of the present invention are: through the coordination of the driving assembly, the traction bolt, and the sensing assembly, the operating efficiency is improved, manpower is liberated, not only the labor cost is reduced, but also the errors in human operation can be reduced, full automation is achieved, the automation level is improved, and the competitiveness of the enterprise is enhanced.

[0029] refer to Figure 1-Figure 3 An automatic unhooking device includes a bracket assembly 1, on which a traction bolt 2 and a driving component 3 for driving the traction bolt 2 to move up and down are provided. The bracket assembly 1 includes a vertical plate 7 and a first through plate 8, a second through plate 9, and a third through plate 10 fixedly connected to the vertical plate 7 and arranged in parallel with each other. A through hole 11 is provided at a parallel position on the three through plates for the traction bolt 2 to pass through when it moves up and down. Figure 4The drive assembly 3 includes a guide sleeve 15 and an electric push rod 16 that can move up and down within the guide sleeve 15. The bottom of the guide sleeve 15 is mechanically connected to the first through plate 8. In the present invention, a bolt connection is used, but this connection method is not limited to this method, as long as the connection purpose can be achieved. The top of the electric push rod 16 is connected to the top of the traction bolt 2 via a connecting rod plate 6. This connection is not limited to a plate-like connection, and can also be a shaft-like connection, as long as the electric push rod 16 can move up and down and drive the traction bolt 2 to move up and down. The automatic uncoupling device also includes a signal component 17, which can be set at any position on the automatic uncoupling device. The signal component 17 is used to transmit and convey signals to drive the electric push rod 16 of the drive assembly 3 to move up and down, thereby driving the traction bolt 2 to move up and down. The signal component 17 can use wireless reception, wired reception, or other reception methods. In the present invention, wired reception is used. The automatic uncoupling device of the present invention also includes a sensing component 4, which is used to sense the movement of the traction bolt 2 up and down, thereby completing the uncoupling operation. The sensing component 4 includes a support plate 18 and two sensing switches 5 arranged on the two side edges of the support plate 18 in the vertical direction, one above and one below. The sensing component 4 also includes a limit pin 14 arranged on the traction bolt 2. The limit pin 14 is arranged on the opposite surface of the traction bolt 2. When the traction bolt 2 moves up and down, the limit pin 14 follows the movement and then contacts the sensing switch 5. Limit plates 12 and limit grooves 13 opened on the limit plates 12 are relatively arranged on both sides of the support plate 18. The limit pin 14 moves up and down in the limit groove 13.

[0030] refer to Figure 5 The present invention also provides an AGV tractor, including the automatic unhooking device B of the present invention, which is mechanically connected to the vehicle body A through the vertical plate 7 of the bracket assembly 1.

[0031] The main function of the present invention is to free up manpower and realize full automation when towing a trolley or corresponding goods. When the control center of the AGV tractor sends a signal and the automatic unhooking device B receives the signal, the electric push rod 16 starts to move upward, thereby driving the traction bolt 2 to move upward. When the traction bolt 2 moves upward, the limit pin 14 set on the traction bolt 2 will move upward and contact the induction switch 5 located in the upper position of the support plate 18. At this time, the traction bolt 2 moves into place, and the towed trolley or goods are automatically unhooked. Please refer to Figure 4, which is the state of upward movement and movement into position. The position of the induction switch 5 is adjustable and can be adjusted according to the required height of the towing hook. When it is necessary to lock the towed vehicle or cargo, the above movement process is reversed. At this time, the induction switch 5 located on the lower part of the support plate 18 contacts the limit pin 14, and the traction bolt 2 moves into position, locking the towed vehicle or cargo. In order to prevent the traction bolt 2 from being disturbed by the outside during operation, resulting in the limit pin 14 not stopping when contacting the induction switch 5 and causing accidental disengagement, the upper part of the limit groove 13 is closed or a speed limit plate is installed to avoid the accidental disengagement of the traction bolt 2, thereby improving the overall safety of the device. In addition, for aesthetic and safety reasons, a shell is also installed on the outside of the drive component 3 to protect the drive component 3.

[0032] The above embodiments are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
