[0001] This utility model relates to the field of AGV (Automated Guided Vehicle) technology, specifically a high-pressure oil source based on an AGV. Background Technology

[0002] With the development of technology, various industries, especially labor-intensive enterprises, have increasingly higher requirements for factory automation, leading to the emergence of AGVs (Automated Guided Vehicles) responsible for the transportation of products, semi-finished products, and raw materials. AGVs are transport vehicles equipped with electromagnetic or optical automatic guidance devices, capable of traveling along a prescribed guide path, and possessing safety protection and various transfer functions.

[0003] In the existing technology, when the hydraulic cylinder and oil tank in the AGV are moving, if they encounter bumps, the oil tank is fixedly connected inside the AGV. The bumps cause the oil tank to move inside the AGV, resulting in cracks at the connection between the oil tank and the hydraulic cylinder.

[0004] Therefore, a high-pressure oil source based on AGV (Automated Guided Vehicle) is proposed to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] See Figure 1 - Figure 7 This embodiment provides a high-pressure oil source based on an AGV trolley, including an AGV trolley body 1, an installation mechanism 2 installed inside the AGV trolley body 1, a drive mechanism 3 installed inside the AGV trolley body 1, and moving wheels 4 installed inside the AGV trolley body 1. The mounting mechanism 2 includes a fixed plate 21. A mounting horizontal plate is fixedly connected to the front of the inner wall of the AGV body 1. The fixed plate 21 is fixedly connected to the upper surface of the mounting horizontal plate. A first limiting rod 22 is fixedly connected to the side of the fixed plate 21. A first moving rod 23 is slidably connected to the outer wall of the first limiting rod 22. A first toothed block 24 is fixedly connected to the back of the first moving rod 23. A rotating rod 25 is rotatably connected to the upper surface of the mounting horizontal plate through a bearing. A circular gear is fixedly sleeved on the outer wall of the rotating rod 25. A second limiting rod 28 is fixedly connected to the side of the fixed plate 21. A second moving rod 27 is slidably connected to the outer wall of the second limiting rod 28. A second toothed block 26 is fixedly connected to the front of the second moving rod 27.

[0019] The electric telescopic rod 211 drives the first moving rod 23 to move to the right, the first moving rod 23 drives the first tooth block 24 to move to the right, the first tooth block 24 drives the sprocket to rotate counterclockwise, the sprocket drives the second tooth block 26 to move to the left, and the second tooth block 26 drives the second moving rod 27 to move to the left, thereby fixing the hydraulic oil tank 37.

[0020] The first tooth block 24 meshes with the spur gear, the second tooth block 26 meshes with the spur gear, the first moving rod 23 and the two second moving rods 27 form a group, and the second moving rods 27 are L-shaped.

[0021] The first tooth block 24 drives the sprocket to rotate, and the sprocket drives the second tooth block 26 to move, thereby causing the first moving rod 23 and the second moving rod 27 to move towards each other.

[0022] A pressure block 29 is fixedly sleeved on the outer wall of the rotating rod 25. The bottom of the pressure block 29 has a rounded corner 210. When the rotating rod 25 is rotated by the spur gear, the rotating rod 25 drives the top pressure block 29. The pressure block 29 limits the top of the hydraulic oil tank 37. The rounded corner 210 can improve the smoothness of the pressure block 29 rotating to the top of the hydraulic oil tank 37.

[0023] An electric telescopic rod 211 is fixedly connected to the top of the upper surface of the mounting plate. The output end of the electric telescopic rod 211 is fixedly connected to the back of the first moving rod 23. The electric telescopic rod 211 drives the first moving rod 23 to move to the right.

[0024] The two first limiting rods 22 are arranged vertically, and the two second limiting rods 28 are arranged vertically. The vertical arrangement of the first limiting rods 22 and the second limiting rods 28 can effectively limit the movement trajectory of the first moving rod 23 and the second moving rod 27.

[0025] The drive mechanism 3 includes a crossbar 31, which is fixedly connected to the side of the AGV trolley body 1. A frame 32 is fixedly connected to the upper surface of the crossbar 31. A slide rail 33 is fixedly connected to the side of the frame 32. A bucket 34 is slidably connected to the outer wall of the slide rail 33. A slide rod 35 is fixedly connected to the lower surface of the frame 32. A lifting hydraulic cylinder 36 is fixedly connected to the bottom of the inner wall of the AGV trolley body 1. A hydraulic oil tank 37 is placed on the upper surface of the mounting plate.

[0026] The AGV trolley body 1 has a connecting plate 38 fixedly connected to the front. A support leg hydraulic cylinder 39 is fixedly connected to the upper surface of the connecting plate 38. A support plate 310 is fixedly connected to the bottom of the output end of the support leg hydraulic cylinder 39. The hydraulic oil tank 37 is connected to the lifting hydraulic cylinder 36 by an oil circuit. The hydraulic oil tank 37 is also connected to the support leg hydraulic cylinder 39 by an oil circuit.

[0027] The AGV body 1 is equipped with a DC power supply, which drives the moving wheels 4 to move and navigate in low-power mode. After reaching the target workstation, the AGV stops. At this time, the control system activates the hydraulic station driven by the DC power supply, controlling the four outrigger hydraulic cylinders 39 to extend. The support plate 310 at the bottom contacts the ground to ensure stable support of the vehicle body. The system connects to an external 380V AC power supply and switches the power source of the hydraulic station to high-power mode. The hydraulic oil tank 37 installed on the crossbar 31 starts to work, driving the two lifting hydraulic cylinders 36. The lifting hydraulic cylinder 36 pushes the frame 32 upward along the guide rail 35, driving the bucket 34 to move along the slide rail 33 to lift the heavy object. The two lifting hydraulic cylinders 36 are controlled synchronously in real time through feedback from the displacement sensor. This is existing technology and will not be elaborated on further. This ensures smooth lifting. After the operation is completed, the lifting hydraulic cylinder 36 descends and resets under synchronous control. The system disconnects the external AC power, the hydraulic station power is switched back to the trolley DC power, and the outrigger hydraulic cylinder 39 is controlled to retract. Finally, the AGV returns to low-power movement state and drives away from the work position.

[0028] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
