[0002] AGV (Automated Guided Vehicles) is also known as unmanned guided vehicles, automatic guided vehicles or laser guided vehicles. Its notable feature is unmanned driving. The AGV is equipped with an automatic guidance system, which can ensure that the system can automatically travel along the predetermined route without the need for manual navigation, and automatically transport goods or materials from the starting point to the destination. The driving path of the AGV can be flexibly changed according to changes in warehouse cargo space requirements, production process flow, etc., and the cost of changing the operating path is very low compared to traditional conveyor belts and rigid transmission lines. In the existing technology, when performing traction operations, AGVs often need to be equipped with additional traction mechanisms to connect with the towed cargo trolleys, etc. Different cargo trolleys may need to be equipped with different traction mechanisms, and their versatility is poor.

DETAILED DESCRIPTION

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0035] like Figure 1 As shown, the clamping type traction AGV trolley of this embodiment includes a chassis 10, a shell 11 surrounding the periphery of the chassis, and a top plate 12 mounted on the shell 11. Specifically, a walking mechanism 20 and a clamping mechanism 30 are provided on the chassis 10.

[0036] like Figure 2 As shown, the clamping mechanism 30 of this embodiment includes a lifting platform 31, a lifting support assembly, a lifting drive assembly, and a clamping assembly. Specifically, the lifting support assembly supports and guides the lifting platform during lifting motion; the lifting drive assembly drives the lifting platform during lifting motion; and the clamping assembly clamps the towed cargo trolley. The top plate 12 of this embodiment is provided with a clearance hole 121 for the lifting platform 31. An outer frame surrounding the lifting platform 31 is mounted on the top plate 12, constraining and guiding the lifting motion of the lifting platform 31.

[0037] In this embodiment, the lifting drive assembly includes a first rail 32 mounted on the chassis 10, a first slide 33 slidably engaged with the first rail 32, and a lifting drive mechanism mounted on the chassis 10 for driving the first slide 33 along the first rail 32. The top surface of the first slide 33 is formed as an inclined surface 331 that is inclined relative to the chassis, and a first cantilever 34 is mounted on the lifting platform 31 to slidably engage with the inclined surface 331. In this embodiment, the first rail 32 is provided as two parallel rails. Preferably, the lower ends of the first cantilever 34 are provided with first rollers 35 that engage with the inclined surface 331 to reduce resistance when the first cantilever 34 moves along the inclined surface 331. Preferably, two first cantilever arms 34 are provided, one on each side of the lifting platform 31. Specifically, in this embodiment, the lifting drive mechanism includes a drive motor 36 mounted on the chassis 10 and a threaded screw 37 drivingly connected to the drive motor 36. Bearing blocks 38 are provided at each end of the threaded screw 37. A nut 39 is mounted on the first slide 33 to threadably engage with the threaded screw 37. In this embodiment, the output shaft of the drive motor 36 is connected to the threaded rod 37 via a coupling 40. The threaded rod 37 is parallel to the first rail 32. Thus, the drive motor 36 drives the threaded rod 37 to rotate, thereby driving the nut 39 to move along the threaded rod 37, thereby driving the first slide 33 to move along the first rail 32, causing the first cantilever 34 to move relative to the inclined surface 331, and driving the lifting platform 31 to perform an upward or downward lifting motion.

[0038] In this embodiment, the clamping assembly includes a fixed splint 41 and a movable splint 42 that are relatively arranged. The fixed splint 41 is arranged on the lifting platform 31. The lifting platform 31 is provided with a second track 43. The second track 43 is parallel to the first track 32, and the movable splint 42 is slidably matched with the second track 43. The second track 43 of this embodiment is set as two parallel to each other. The movable splint 42 of this embodiment is provided with a second cantilever 44 extending into the bottom of the lifting platform 31, and a guide slide 45 is provided on the chassis 10. The guide slide 45 is provided with a guide bevel 46 that is tilted relative to the chassis 10, and the second cantilever 44 is limitedly matched with the guide bevel 46. Specifically, a clearance groove 311 for making way for the second cantilever 44 is provided on the lifting platform 31. There are two guide slides 45 in this embodiment, and the two guide slides 45 are respectively located on both sides of the first slide 33. Preferably, the lower end of the second cantilever 44 is provided with a second roller 47 that engages with the guide chute 46 to reduce resistance as the lower end of the second cantilever 44 moves along the guide chute 46. Thus, when the second cantilever 44 moves along the guide chute 46, the sliding engagement between the movable clamping plate 42 and the second track 43 drives the movable clamping plate 42 to move along the second cantilever 44. Specifically, the inclination direction of the guide chute 46 relative to the chassis 10 is the same as the inclination direction of the inclined surface 331 relative to the chassis 10. Furthermore, the inclination angles of the guide chute 46 and the inclined surface 331 relative to the chassis 10 can also be set to be equal, which will not be further described.

[0039] In a preferred embodiment of this embodiment, anti-slip teeth 411 and anti-slip teeth 421 are respectively provided on the facing sides of the fixed clamping plate 41 and the movable clamping plate 42. Preferably, the anti-slip teeth 411 and anti-slip teeth 421 are arranged at an angle, and the anti-slip teeth 411 on the fixed clamping plate 41 and the anti-slip teeth 421 on the movable clamping plate 42 are inclined in opposite directions. By providing the anti-slip teeth 411 and anti-slip teeth 421 on the facing sides of the fixed clamping plate 41 and the movable clamping plate 42, respectively, the stability and reliability of the clamping can be enhanced.

[0040] The lifting support assembly of this embodiment includes support units disposed between the chassis 10 and the lifting platform 31. Specifically, this embodiment comprises four support units, one located at each of the four diagonal positions of the lifting platform 31. The support units comprise a support seat 48 disposed on the chassis 10 and a support rod 49 fixedly connected to the lifting platform 31. The support seat 48 is provided with a linear bearing 50 that cooperates with the support rod 49. The cooperation between the support rod 49 and the linear bearing 50 provides support and guidance for the lifting platform 31.
