Description

Technical Field

[0001] This utility model relates to the field of AGV (Automated Guided Vehicle) technology, and more specifically, to an AGV chassis component. Background Technology

[0002] AGV is an abbreviation for Automated Guided Vehicle. It is a transport vehicle equipped with electromagnetic or optical automatic guidance devices, enabling it to travel along a predetermined guide path and providing safety protection and various transfer functions. Simply put, it is an unmanned, automated material handling equipment.

[0003] However, when using traditional AGV carts, goods are usually placed directly on the top of the cart's pallet. This can lead to poor stability on both sides when the goods are long, causing them to tilt during transport and eventually slip off, thus affecting normal use. Furthermore, the lack of anti-collision mechanisms means that when the AGV is in use, its four corners are prone to collisions with objects that suddenly appear in the outside world, which affects the service life of the AGV. Utility Model Content

[0004] (a) Technical problems to be solved To address the problems existing in the prior art, this utility model provides an AGV chassis assembly to solve the technical problem mentioned in the background art, where traditional AGVs often place goods directly on the top of the AGV pallet, resulting in poor stability on both sides when the goods are long, causing the goods to tilt and slip during transportation.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: an AGV chassis assembly, including a frame, with legs fixedly mounted on the upper surface of the frame at each of the four corners, and trays fixedly mounted on the upper surface of each leg. A square groove is formed inside the frame at the center position, and a double-headed cylinder is fixedly mounted inside the square groove. The output ends of the double-headed cylinders pass through the frame and are fixedly mounted with telescopic blocks. Telescopic grooves are formed on both sides of the frame, and the telescopic blocks are located inside the telescopic grooves. Electric push rods are fixedly mounted on the outer walls of the telescopic blocks, and support blocks are fixedly mounted on the output ends of the electric push rods. Connecting blocks are fixedly mounted on the outer walls of each leg, and connecting shafts are fixedly mounted on the upper surfaces of the connecting blocks. Rotating sleeves are rotatably mounted on the outer sides of the connecting shafts.

[0006] The present invention is further configured such that anti-collision rollers are provided on the outer side of the rotating sleeve, and rotating rings are movably provided on the outer wall of the rotating sleeve above the anti-collision rollers. Each rotating ring has a limiting nut at its upper end, and the limiting nut is threadedly connected to the connecting shaft to facilitate limiting the upper end of the anti-collision rollers.

[0007] The present invention is further provided that anti-collision rubber blocks are fixed at both ends of the frame to facilitate the protection of both ends of the frame.

[0008] The present invention is further configured such that a base is fixedly provided on the lower end face of the frame, and wheels are rotatably provided on the outer wall of the base at the four corners. An avoidance groove is provided on the lower end face of the base at the middle position. A motor is provided inside the avoidance groove, and a connecting plate is fixedly provided on the output end of the motor. The connecting plate is fixedly connected to the inner wall of the avoidance groove, which facilitates the movement of the vehicle.

[0009] The present invention is further configured such that a hydraulic cylinder is fixedly provided at the tail end of the motor, and a support block is fixedly provided at the output end of the hydraulic cylinder, so as to facilitate the wheels of the trolley to detach from the ground.

[0010] The present invention is further provided with a protective pad fixed on the upper surface of the tray, which facilitates the protection of the upper part of the tray and reduces wear.

[0011] The present invention is further configured such that the support blocks are located on both sides of the pallet, which facilitates support at both ends of the goods to make them more stable.

[0012] The present invention is further configured such that the support block can enter the interior of the avoidance groove, making it convenient to store the support block.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides an AGV chassis assembly, which has the following advantages: 1. By setting up a pallet, square groove, double-headed cylinder and telescopic block, the user can control the output end of the double-headed cylinder to drive the telescopic block to move so that the telescopic block is located below both ends of the item. Then, the electric push rod is controlled to move the support block upward so that the support block contacts the bottom of the item, thereby achieving the effect of supporting both ends of the item, making the trolley more stable when transporting items.

[0014] 2. By setting up connecting blocks, connecting shafts, rotating sleeves, and anti-collision rollers, users can fit the rotating sleeve onto the outside of the connecting shaft, then fit the anti-collision roller onto the outside of the rotating sleeve, and then fit the rotating ring onto the top of the anti-collision roller. By rotating the limiting nut, the upper end of the rotating ring is limited. When the trolley collides with an external object, the anti-collision roller can transfer the impact force received by the device to reduce the collision force, thereby achieving the effect of protecting the device. At the same time, the anti-collision rubber block can also protect the front and rear ends of the trolley, making it convenient to use.

[0015] 3. By setting up a base, a dodging groove, a motor, and a hydraulic cylinder, when it is necessary to adjust the movement direction of the trolley, the output end of the hydraulic cylinder can be controlled to drive the support block downward until it is exposed and in contact with the ground, thereby causing the wheels to leave the ground. Then, the motor is controlled to drive the trolley to rotate, so as to achieve the effect of adjusting the movement direction of the trolley. Finally, the hydraulic cylinder is controlled to retract the support block for easy continued transportation. Attached Figure Description
