Description

Technical Field

[0001] This utility model relates to the field of transportation equipment, specifically to an automated guided vehicle (AGV). Background Technology

[0002] AGVs, short for Automated Guided Vehicles, are unmanned short-distance transportation vehicles. With their high efficiency, flexibility, and safety, AGVs are playing an increasingly important role in modern logistics and warehousing.

[0003] However, existing hydraulic AGVs have the following drawbacks: 1. Traditional hydraulic AGVs have hydraulic pumps and hydraulic oil installed inside, and due to the large size of these components, the vehicle body is designed to be too large, making it difficult to meet the needs of small spaces; 2. If not properly maintained, traditional hydraulic AGVs are prone to oil leaks under prolonged high loads, which is particularly detrimental to hygiene in oil-free workshops (food factories, pharmaceutical factories, etc.), affecting floor cleanliness; 3. Precision: Because traditional hydraulic AGVs rely on hydraulic oil pumps, the lifting or pushing / pulling precision of the pumps currently used cannot meet high requirements, necessitating significant investment to achieve these requirements. Therefore, those skilled in the art have provided an automated guided vehicle to address the problems mentioned in the background. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic transport trolley, including a gantry, a box body installed on one side below the gantry, and a fork sleeve installed on the other side below the gantry.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-3 In this embodiment, an automatic transport trolley is provided, including a gantry 14, a box is installed on one side below the gantry 14, and a fork sleeve 16 is installed on the other side below the gantry 14. A lifting mechanism 15 is installed inside the fork sleeve 16, and rollers are installed on both the fork sleeve 16 and the box.

[0023] The lifting mechanism 15 includes a lead screw 151, a lead screw nut installed on the outside of the lead screw 151, and a rotating arm 153 and a rotating arm 154 installed inside the fork sleeve 16 on both sides of the lead screw 151. The lower end of the rotating arm 153 is rotatably connected to the fork sleeve 16, and the lower end of the rotating arm 154 is slidably connected to the fork sleeve 16. A moving column 152 is rotatably connected between the rotating arm 153 and the rotating arm 154, and the moving column 152 is connected to the lead screw nut. A lifting frame 156 is rotatably connected to the upper end of the rotating arm 154, and a sliding groove is provided on the lifting frame 156. A connecting rod 155 is rotatably connected to the upper end of the rotating arm 153, and the connecting rod 155 is located inside the sliding groove.

[0024] A servo motor is installed inside the housing. The servo motor drives the lead screw 151 to rotate and the lead screw nut to move. The movement of the lead screw nut pushes the moving column 152 to move. The movement of the moving column 152 causes the rotating arms 153 and 154 on both sides to rotate, thereby raising the lifting frame 156. The lifting frame 156 raises the upper part of the fork sleeve 16, and the sleeve 16 lifts the object.

[0025] In this embodiment, specifically, a fork anti-collision photoelectric sensor 13 is installed at the front end of the fork sleeve 16. The fork anti-collision photoelectric sensor 13 prevents the forks from colliding with objects when moving.

[0026] In this embodiment, specifically, a SLAM navigator 6 is installed on the top of the enclosure, a laser obstacle avoidance radar 10 is installed on the top of the gantry 14, a laser obstacle avoidance radar 7 is installed extending to one side of the upper end of the gantry 14, and an emergency stop button 8 is installed on one side of the gantry 14.

[0027] In this embodiment, specifically, a USB interface 1, an HDMI interface 2 and a network port 3 are provided on one side of the cabinet, and a crossbar is provided in the middle of the door frame 14, on which a multi-pass antenna 9 is installed.

[0028] In this embodiment, specifically, a cargo positioning photoelectric sensor 5 is installed on the front side of the container above the fork sleeve 16. The positioning photoelectric sensor 5 detects whether the object has moved close to the mast 14, thereby ensuring that the object is stably installed on the fork sleeve 16.

[0029] In this embodiment, specifically, a manual charging port 4 is installed on the front side of the box, and a battery power switch 11 and a vehicle power switch 12 are installed on the side of the USB interface 1 of the box.

[0030] In this embodiment, specifically, a battery is installed inside the casing. The battery used is a rechargeable battery.

[0031] This AGV forklift is based on SLAM navigation. It utilizes the SLAM laser navigation AGV principle, extracting point cloud features from surrounding environmental data to determine the forklift's position and attitude for automatic navigation. This eliminates the need for traditional reflector installations and offers greater flexibility in application environments, free from the limitations of reflective strip placement. Furthermore, laser obstacle avoidance radar prevents direct collisions with surrounding objects, ensuring the safety of on-site personnel.

[0032] During lifting, the lifting reducer rotates the lead screw, the lead screw nut moves, and the lifting mechanism begins to lift. The lifting active mechanism drives the lifting driven mechanism through the tie rod, so that the two forks have a total of 4 support points to support the goods, making them more stable and reliable.

[0033] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
