Description

Technical Field

[0001] The utility model belongs to the technical field of automatic transportation, and specifically relates to an AGV cart with an anti-falling function. Background Art

[0002] Traditionally, in the warehousing and logistics industries, in order to transfer materials from one location to another, manual handling is usually required, which not only consumes time and human resources, but also has potential safety risks and low work efficiency. AGVs usually use sensors and navigation systems to detect and avoid obstacles and perform handling tasks according to a predetermined path or program.

[0003] During the process of an AGV cart transporting goods, in case of an emergency braking situation, due to sudden braking, the goods may be affected by inertial force, resulting in tilting or overturning. Content of the Utility Model

[0004] In order to overcome the above defects, the utility model provides an AGV cart with an anti-falling function, and solves the problem that during the process of an AGV cart transporting goods, in case of an emergency braking situation, due to sudden braking, the goods may be affected by inertial force, resulting in tilting or overturning.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an AGV cart with an anti-falling function, including rollers, a support frame is installed on the rollers, a frame body is connected to the support frame, long grooves are formed on both sides of the frame body, a shielding device is connected in the long grooves, a buffer device is connected to the shielding device, the shielding device includes two connecting plates, a hydraulic cylinder is connected to the connecting plates, a top plate is connected to the hydraulic cylinder, a moving frame is connected to the top plate, a baffle is lapped on the moving frame, a rotating ring is connected to one side of the baffle, and a fixed shaft is rotatably connected in the rotating ring.

[0006] As a further scheme of the utility model: one side of the connecting plate is connected to the support frame, and the moving frame is sleeved and slidably connected to the outside of the support frame and the frame body.

[0007] As a further scheme of the utility model: the baffle corresponds to the position of the frame body, and the fixed shaft is connected in the long groove.

[0008] As a further scheme of the utility model: the buffer device includes a telescopic rod, the telescopic rod is connected to the baffle, and a buffer plate is connected to the telescopic rod.

[0009] As a further scheme of the utility model: the buffer plate corresponds to the position of the baffle, and a pulling-back spring is sleeved outside the telescopic rod.

[0010] As a further solution of the present utility model: one end of the pulling-back spring is connected to the baffle, and the other end of the pulling-back spring is connected to the lower part of the buffer plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. For the AGV cart with the anti-falling function, by setting the connecting plate, hydraulic cylinder, top plate, moving frame, fixed shaft, rotating ring and baffle, when the goods are placed on the frame body, the hydraulic cylinder is started at this time. The hydraulic cylinder drives the top plate to move, the top plate drives the moving frame to move, the moving frame exerts a thrust on the baffle, the thrust drives the baffle to rotate, the baffle drives the rotating ring to rotate outside the fixed shaft. Subsequently, when the baffle rotates to a certain angle, the operation of the hydraulic cylinder is stopped at this time. When the baffle encounters an impact, the moving frame blocks the baffle at this time, thus avoiding the situation where emergency braking is required. Due to sudden braking, the goods may be affected by the inertial force, resulting in the problem that they may tilt or overturn.

[0013] 2. For the AGV cart with the anti-falling function, by setting the telescopic rod, buffer plate and pulling-back spring, when the goods move on the frame body due to the inertial force, a thrust is applied to the buffer plate at this time. The thrust drives the telescopic rod and the pulling-back spring to be compressed. Subsequently, the pulling-back spring exerts an elastic force on the buffer plate, and the elastic force drives the buffer plate to move, so that it can be quickly reset, avoiding the problem that a strong impact damages the baffle.

[0019] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.

[0020] Such asFigures 1-4 As shown in the figure, the present utility model provides a technical solution: an AGV cart with a function of preventing falling, including a roller 1, a support frame 2 is installed on the roller 1, a frame body 3 is connected to the support frame 2, long slots 4 are opened on both sides of the frame body 3, a shielding device 5 is connected in the long slots 4, a buffer device 6 is connected to the shielding device 5, the buffer device 6 includes a telescopic rod 61, the telescopic rod 61 is connected to a baffle 57, a buffer plate 62 is connected to the telescopic rod 61, the buffer plate 62 corresponds to the position of the baffle 57, a pulling-back spring 63 is sleeved outside the telescopic rod 61. By setting the pulling-back spring 63, when the buffer plate 62 is not impacted, at this time the pulling-back spring 63 applies an elastic force to the buffer plate 62 to keep it stable. When the buffer plate 62 is buffered, at this time the pulling-back spring 63 applies an elastic force to the buffer plate 62, and the elastic force drives the buffer plate 62 to move, so that it can be quickly reset;

[0021] One end of the pulling-back spring 63 is connected to the baffle 57, the other end of the pulling-back spring 63 is connected under the buffer plate 62. The shielding device 5 includes two connecting plates 51, the connecting plates 51 are connected to one side of the support frame 2, a moving frame 54 is sleeved and slidably connected outside the support frame 2 and the frame body 3, a hydraulic cylinder 52 is connected to the connecting plate 51, a top plate 53 is connected to the hydraulic cylinder 52, and a moving frame 54 is connected to the top plate 53. By setting the moving frame 54 and the support frame 2, the moving frame 54 cooperates with the support frame 2 to realize the support frame 2 to limit the moving frame 54 to prevent the moving frame 54 from shaking when moving;

[0022] A baffle 57 is lapped on the moving frame 54, the baffle 57 corresponds to the position of the frame body 3, a fixed shaft 55 is connected in the long slot 4, a rotating ring 56 is connected to one side of the baffle 57. By setting the rotating ring 56 and the fixed shaft 55, the rotating ring 56 cooperates with the fixed shaft 55 to realize that the rotating ring 56 can freely rotate outside the fixed shaft 55;

[0023] The fixed shaft 55 is rotatably connected in the rotating ring 56.

[0024] The working principle of the present utility model is:

[0025] When the goods are placed on the frame 3, the hydraulic cylinder 52 is activated at this time. The hydraulic cylinder 52 drives the top plate 53 to move, and the top plate 53 drives the moving frame 54 to move. The moving frame 54 exerts a thrust on the baffle 57, and the thrust drives the baffle 57 to rotate. The baffle 57 drives the rotating ring 56 to rotate outside the fixed shaft 55. Subsequently, when the baffle 57 rotates to a certain angle, the operation of the hydraulic cylinder 52 is stopped at this time. When the baffle 57 encounters an impact, the moving frame 54 blocks the baffle 57 at this time. When the goods move on the frame 3 due to inertia force, a thrust is applied to the buffer plate 62 at this time. The thrust drives the telescopic rod 61 and the pulling-back spring 63 to be compressed. Subsequently, the pulling-back spring 63 exerts an elastic force on the buffer plate 62, and the elastic force drives the buffer plate 62 to move, so that it can be quickly reset. Thus, the protection of the goods is completed.
