Description

Technical Field

[0001] This utility model relates to the field of AGV (Automated Guided Vehicle) vehicles, specifically an AGV (Automated Guided Vehicle) concealed lifting mechanism. Background Technology

[0002] The AGV (Automated Guided Vehicle) with a low-profile lifting mechanism mainly transports materials by lying low to the bottom of the material rack and using a lifting mechanism to lift the rack. It is mainly used for the transfer of material racks and material carts, effectively reducing labor costs and alleviating the labor intensity of workers. AGVs with low-profile lifting mechanisms are widely used in industries such as automobiles, electronics, home appliances, and furniture.

[0003] However, since the lurking lifting AGV trolley requires a lifting base, when the material being transported is not very regular and part of the material is in contact with the lower part of the base, the material is easily clamped when the base descends, thus causing the trolley to drag the material when it moves. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an AGV (Automated Guided Vehicle) submersible lifting mechanism, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: an AGV (Automated Guided Vehicle) submersible lifting mechanism, including an AGV trolley, an embedded compartment on the upper surface of the AGV trolley, and placement grooves on both sides of the embedded compartment on the upper surface of the AGV trolley. A lifting mechanism is installed inside the embedded compartment. The lifting mechanism includes: a lifting base, a scissor bracket, and a lifting pad. An anti-pinch rod is installed on the lower surface of the lifting pad inside the placement groove. Anti-pinch swing arms are provided on both sides of the anti-pinch rod. A push hydraulic cylinder is installed inside the anti-pinch rod. A swing linkage connects the push hydraulic cylinder and the anti-pinch swing arm.

[0006] As a further embodiment of this utility model: a push slider is installed on one side of the lower end of the lifting mechanism, a drive screw is installed inside the push slider, and an embedded rod is installed on the inner side of the lower end of the anti-pinch rod inside the placement groove.

[0007] As a further improvement of this utility model: an identification mechanism is installed on the front surface of the AGV, and rollers are installed on the bottom of the AGV.

[0008] As a further embodiment of this utility model: the swing linkage is connected to the anti-pinch swing arm and the hydraulic rod of the push hydraulic cylinder by a movable shaft, and a rotating shaft is installed between the anti-pinch swing arm and the anti-pinch sleeve rod.

[0009] As a further improvement of this utility model, a drive motor is installed at the end of the drive screw that is away from the push slider.

[0010] As a further embodiment of this utility model: the drive screw is rotatably connected to the push slider, and a limit slide rod is installed between the push slider and the lifting base.

[0011] As a further improvement of this utility model, the inner diameter of the mounting groove is greater than the outer diameter of the anti-pinch rod.

[0012] As a further improvement of this utility model, the identification mechanism is electrically connected to the AGV trolley.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The hydraulic cylinder pushes the swing linkage to swing, and the swing linkage and the anti-pinch swing arm rotate at the same time. This controls the two anti-pinch swing arms to swing outward as a whole. When descending, the anti-pinch swing arm will be stuck above the AGV trolley. The lifting pad will not press against the upper surface of the AGV trolley. By controlling the AGV trolley to move away from the placement surface, the object will be removed from the top of the lifting pad. Attached Figure Description

[0021] 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.

[0022] like Figure 1-5 As shown, this embodiment provides an AGV (Automated Guided Vehicle) lurking lifting mechanism, including an AGV trolley 1. An embedded compartment 101 is formed on the upper surface of the AGV trolley 1. Placement slots 102 are formed on both sides of the embedded compartment 101 on the upper surface of the AGV trolley 1. A lifting mechanism 302 is installed inside the embedded compartment 101. The lifting mechanism 302 includes: a lifting base 301, a scissor bracket 303, and a lifting pad 3. An anti-pinch rod 305 is installed on the lower surface of the lifting pad 3 inside the placement slot 102. The inner diameter of the placement slot 102 is long. The length is greater than the outer diameter of the anti-pinch rod 305. Anti-pinch swing arms 307 are provided on both sides of the anti-pinch rod 305. A rotating shaft is installed between the anti-pinch swing arms 307 and the anti-pinch rod 305. A push hydraulic cylinder 309 is installed inside the anti-pinch rod 305. A swing connecting rod 308 is connected between the push hydraulic cylinder 309 and the anti-pinch swing arms 307. A movable shaft is connected between the swing connecting rod 308 and the hydraulic rods of the anti-pinch swing arms 307 and the push hydraulic cylinder 309. A control circuit for driving the push hydraulic cylinder 309 is provided inside the AGV trolley 1.

[0023] like Figure 2-3 As shown, in this embodiment, a push slider 306 is installed on one side of the lower end of the lifting mechanism 302. A drive screw 304 is installed inside the push slider 306. A drive motor is installed at the end of the drive screw 304 that is away from the push slider 306. The drive screw 304 is meshed and rotatably connected to the push slider 306. A limit slide rod is installed between the push slider 306 and the lifting base 301. An embedded rod 310 is installed on the inner side of the lower end of the anti-pinch rod 305 inside the placement groove 102. An identification mechanism 2 is installed on the front surface of the AGV trolley 1. A roller 4 is installed below the AGV trolley 1. The identification mechanism 2 is electrically connected to the AGV trolley 1.

[0024] The working principle of this utility model is as follows: When in use, the AGV trolley 1 moves to a position below the object to be transported. The internal motor drives the drive screw 304 to rotate, which in turn engages with the push slider 306. This pushes the slider 306 to slide within the groove of the lifting base 301, thereby controlling the scissor bracket 303 to lift the object. After the AGV trolley 1 moves to the object to be transported, the scissor bracket 303 folds down to lower the material. When the transported material is a regular object, the hydraulic cylinder 309 is not driven. When the lifting pad 3 lowers, the anti-pinch rod 305 can be retracted into the placement groove 102. When the transported object is not a regular object... If the structure is too regular (e.g., with ropes), after the lifting pad 3 is raised as a whole, the hydraulic rod of the driving hydraulic cylinder 309 is pushed upwards. The driving hydraulic cylinder 309 will then push the swing link 308 to swing. The swing link 308 and the anti-pinch swing arm 307 will rotate simultaneously, causing the two anti-pinch swing arms 307 to swing outwards. When the lifting pad 3 is moved downwards, the anti-pinch swing arm 307 will get stuck above the AGV trolley 1, preventing the lifting pad 3 from pressing against the upper surface of the AGV trolley 1. By controlling the AGV trolley 1 to move away from the placement surface, the object will be removed from above the lifting pad 3. Then, by controlling the anti-pinch swing arm 307 to retract into the anti-pinch sleeve 305, the lifting pad 3 can be lowered and reset.
