[0025] 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.

[0026] like Figures 1 to 5As shown, an intelligent warehousing AGV trolley is disclosed, including a trolley body 1 and a conversion plate 5. A connecting cavity 2 is provided on the top of the trolley body 1, and grippers 4 are slidably arranged on both sides of the connecting cavity 2. A gripper drive mechanism 7 is provided inside the connecting cavity 2 to drive the grippers 4 on both sides to move closer or further apart. Grip grooves 51 matching the shape of the grippers 4 are provided on both sides of the conversion plate 5. The gripper drive mechanism 7 has drive plates 71 symmetrically slidably arranged inside the connecting cavity 2. Grippers 4 are provided at both ends of the drive plates 71, and a lead screw 72 is threadedly connected to the middle of the drive plates 71. Two external threads with opposite helical directions are symmetrically arranged on the lead screw 72. The two drive plates 71 are respectively connected to the two external threads with opposite helical directions. A drive motor 74 is provided at one end of the lead screw 72 to drive its rotation. In this embodiment, pallets, brackets, or shelves and other cargo-bearing components are assembled and fixed on different... At the top of the conversion plate 5, appropriate cargo-carrying components are selected according to the handling requirements of different items. The top of the trolley body 1 is driven by the gripper drive mechanism 7 inside the connecting cavity 2 to bring the grippers 4 on both sides closer together, so that the conversion plate 5 with the cargo-carrying components can be quickly connected to the trolley body 1. When the cargo-carrying components need to be replaced, the gripper drive mechanism 7 drives the grippers 4 on both sides to move away, releasing the existing conversion plate 5 and removing it. Then, the conversion plate 5 with the required cargo-carrying components is installed on the top of the trolley body 1, realizing quick disassembly and assembly between the conversion plate 5 and the cargo-carrying components, improving replacement efficiency. The drive motor 74 in the gripper drive mechanism 7 drives the lead screw 72 to rotate. The two external threads on the lead screw 72 with opposite helical directions drive the two drive plates 71 to move the grippers 4 on both sides of the connecting cavity 2 closer or further apart, realizing the clamping or release of the conversion plate 5.

[0027] The gripper 4 has a clamping support 41. One end of the gripper support 41 is fixedly connected to the drive plate 71, and the other end of the gripper support 41 is slidably provided with a gripper body 42. An installation groove 45 is opened between the gripper support 41 and the gripper body 42. A tension sensor 44 is installed inside the installation groove 45. The two ends of the tension sensor 44 are respectively connected to the gripper support 41 and the gripper body 42. During the clamping of the conversion plate 5, the gripper body 42 contacts the corresponding groove 51. As the drive plate 71 drives the gripper support 41 to move further, the tension force on the tension sensor 44 gradually increases. The controller presets an upper limit value of tension. The controller collects the real-time tension value of the tension sensor 44. When the real-time tension value is greater than the preset upper limit value of tension, the gripper drive mechanism 7 is controlled to stop operating.

[0028] like Figure 2 and 3As shown, the gripper body 42 has a connecting section 423 that is slidably connected to the gripper support 41. A clearance section 422 is fixedly provided at the top of the end of the connecting section 423 facing away from the gripper support 41. A clamping section 421 is fixedly provided at the top of the clearance section 422. A clamping side 4211 is provided on the side of the clamping section 421 corresponding to the clamping groove 51. The included angle α between the clamping side 4211 and the top of the connecting section 423 is 30~60°. When the gripper 4 clamps and fixes the clamping groove 51, the clamping side 4211 in the gripper body 42 fits against the clamping groove 51. The inclined clamping side 4211 can restrict the movement of the conversion plate 5 in the vertical direction, ensuring the stability of the conversion plate 5 fixed at the top of the connecting cavity 2. Preferably, the included angle α between the clamping side 4211 and the top of the connecting section 423 is 45°.

[0029] Two slide rods 43 are symmetrically arranged on one side of the connecting section 423, and the slide rods 43 are slidably connected to the gripper support 41.

[0030] A support plate 3 is provided on the top of the connecting cavity 2. The support plate 3 increases the support area for the conversion plate 5. A pad 31 is provided on the top of the support plate 3. Both sides of the support plate 3 and the pad 31 are provided with clearance openings 32 corresponding to the clamping claws 4. Specifically, the pad 31 is a rubber plate with good elasticity. When clamping the conversion plate 5, the downward pull of the clamping side 4211 on the conversion plate 5 enables the conversion plate 5 to press the pad, reduce the gap, and improve the stability of the connection.

[0031] A bearing 73 is rotatably mounted in the middle of the lead screw 72. The bearing 73 is fixedly mounted on the top of the trolley body 1, and the bearing 73 provides rotational support for the lead screw 72 on the top of the trolley body 1.

[0032] The connecting cavity 2 is symmetrically provided with two guide rods 75 parallel to the lead screw 72. The two ends of the guide rods 75 are fixedly connected to the inner side of the connecting cavity 2, and the drive plate 71 is slidably connected to the guide rods 75.

[0033] Mounting posts 6 are evenly arranged on the top of the conversion plate 5. The mounting posts 6 have internal threaded holes. The cargo-bearing components are assembled and fixed to the top of the mounting posts 6 by bolts.

[0034] Both sides of the clamping groove 51 are provided with chamfers 52. The chamfers 52 make the clamping groove 51 have a larger opening, which is conducive to the entry of the gripper 4.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
