An anti-collision structure for AGV vehicles

Abstract

This utility model relates to the field of AGV (Automated Guided Vehicle) carts, specifically disclosing an anti-collision structure for AGV carts. The structure includes an AGV cart, a base at its lower end, an anti-collision mechanism on the outer side of one end of the base, an anti-collision frame inside the anti-collision mechanism, and push rods arranged in an array inside the anti-collision frame. A hydraulic sleeve is installed on the outer side of the end of each push rod, and a piston pad is installed inside the hydraulic sleeve at the end of the push rod. A lifting rod is installed below the hydraulic sleeve, and a spring is sleeved on the outer side of each push rod. A fixing link is installed between the end of the hydraulic sleeve furthest from the push rod and the AGV cart. When a collision occurs while the AGV cart is moving, the anti-collision frame will first contact the obstacle. The anti-collision frame will then slide within a limiting groove guided by a limiting slider. Simultaneously, as the anti-collision frame moves, the spring between the hydraulic sleeve and the anti-collision frame is compressed and deformed to dissipate the impact potential energy.

Description

Technical Field

[0001] This utility model relates to the field of AGV (Automated Guided Vehicle) vehicles, specifically an anti-collision structure for AGV vehicles. Background Technology

[0002] AGV is an abbreviation for Automated Guided Vehicle, which refers to a transport vehicle equipped with electromagnetic or optical automatic guidance devices. It can follow a prescribed guidance path and has safety protection and various transfer functions. AGV is a special application of wheeled mobile robots. AGV is a battery-powered, driverless vehicle equipped with non-contact guidance devices. Its main function is to accurately walk and stop at a designated location under computer monitoring, according to path planning and operation requirements, and complete a series of operation functions.

[0003] However, most AGVs currently in use rely on wrapping the outside with anti-collision foam for collision protection. Since the foam wrapping is relatively thin, the anti-collision effect is not good enough. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-collision structure for AGV vehicles, solving the problems mentioned in the background.

[0005] This utility model provides the following technical solution: an AGV (Automated Guided Vehicle) anti-collision structure, including an AGV, a base at the lower end of the AGV, an anti-collision mechanism on the outer side of one end of the base, an anti-collision frame inside the anti-collision mechanism, push rods arranged in an array inside the anti-collision frame, a hydraulic sleeve installed on the outer side of the end of the push rod, a piston pad installed inside the hydraulic sleeve at the end of the push rod, a lifting rod installed below the hydraulic sleeve, a spring sleeved on the outer side of the push rod, and a fixing connecting rod installed between the end of the hydraulic sleeve away from the push rod and the AGV.

[0006] As a further improvement of this utility model: the inner walls at both ends of the anti-collision frame are equipped with limit sliders, and the outer wall of the base is provided with a limit groove corresponding to the position of the limit slider.

[0007] As a further improvement of this utility model, a lifting seat is installed on the upper surface of the AGV trolley.

[0008] As a further improvement of this utility model: the interior of the hydraulic sleeve is filled with hydraulic oil, and the lifting rod and the pushing rod are both movably connected to the hydraulic sleeve.

[0009] As a further improvement of this utility model, the spring is fixedly connected to the anti-collision frame.

[0010] As a further improvement of this utility model, the hydraulic sleeve is fixedly connected to the AGV trolley via the fixed connecting rod.

[0011] As a further improvement of this utility model, the anti-collision frame is slidably connected to the limiting groove via the limiting slider.

[0012] As a further improvement of this utility model: the lower surface of the AGV is equipped with movable rollers, and the outer side of the AGV located near the anti-collision mechanism is equipped with a protective edge strip.

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

[0014] When the AGV is moving as a whole and a collision occurs, the anti-collision frame will first come into contact with the obstacle. The anti-collision frame will then slide inside the limit slide groove guided by the limit slider. At the same time, when the anti-collision frame moves, the spring between the hydraulic sleeve and the anti-collision frame is compressed and deformed to consume the potential energy of the impact.

[0015] When the impact force is large, the spring is compressed and the push rod pushes the piston pad to squeeze the hydraulic oil into the hydraulic sleeve. The hydraulic oil pushes the lifting rod downward to contact the ground, which can slightly raise the head of the AGV to a certain angle to prevent the AGV from tipping over due to collision caused by excessive movement speed.

[0022] 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.

[0023] like Figure 1-5 As shown, this embodiment provides an AGV anti-collision structure, including an AGV 1. A base 5 is provided at the lower end of the AGV 1. An anti-collision mechanism 4 is provided on the outer side of one end of the base 5. An anti-collision frame 401 is provided inside the anti-collision mechanism 4. Push rods 405 are arrayed inside the anti-collision frame 401. A hydraulic sleeve 403 is installed on the outer side of the end of the push rod 405. The hydraulic sleeve 403 is filled with hydraulic oil. The end of the push rod 405 is located within the hydraulic sleeve 403. A piston gasket 407 is installed inside. A lifting rod 408 is installed below the hydraulic sleeve 403. The lifting rod 408 and the push rod 405 are movably connected to the hydraulic sleeve 403. A spring 406 is sleeved on the outside of the push rod 405. The spring 406 is fixedly connected to the anti-collision frame 401. A fixed connecting rod 404 is installed between the end of the hydraulic sleeve 403 away from the push rod 405 and the AGV trolley 1. The hydraulic sleeve 403 is fixedly connected to the AGV trolley 1 through the fixed connecting rod 404.

[0024] like Figure 2-3 As shown, in this embodiment, limit sliders 402 are installed on the inner sidewalls of both ends of the anti-collision frame 401, and limit grooves 6 are opened on the outer sidewall of the base 5 corresponding to the position of the limit sliders 402. The anti-collision frame 401 is slidably connected to the limit grooves 6 through the limit sliders 402. A lifting seat 2 is installed on the upper surface of the AGV trolley 1, and a moving roller is installed on the lower surface of the AGV trolley 1. A protective edge strip 3 is installed on the outer side of the end of the AGV trolley 1 that is close to the anti-collision mechanism 4.

[0025] The working principle of this utility model is as follows: During use, the anti-collision mechanism 4 is assembled as a whole in the traveling direction of the AGV trolley 1. The limiting slider 402 on the side surface of the anti-collision frame 401 is engaged with the inside of the limiting groove 6. The push rod 405 is installed correspondingly inside the anti-collision frame 401. The piston pad 407 at the end of the push rod 405 is limited inside the hydraulic sleeve 403. The cavity between the push rod 405 and the lifting rod 408 inside the hydraulic sleeve 403 is filled with hydraulic oil. When the AGV trolley 1 is traveling normally, the lifting rod 408 is retracted below the hydraulic sleeve 403, not affecting the movement of the rollers. When the AGV trolley 1 is traveling, if a collision occurs... Upon collision, the anti-collision frame 401 will first contact the obstacle. The anti-collision frame 401 will then slide within the limiting groove 6 guided by the limiting slider 402. Simultaneously, as the anti-collision frame 401 moves, the spring 406 between the hydraulic sleeve 403 and the anti-collision frame 401 will be compressed and deformed to dissipate the impact potential energy. When the impact force is large, the spring 406 will be compressed. At the same time, the push rod 405 will push the piston pad 407 to squeeze the hydraulic oil into the hydraulic sleeve 403. The hydraulic oil will push the lifting rod 408 downward to contact the ground. This can slightly raise the head position of the AGV trolley 1 by a certain angle to prevent the AGV trolley 1 from tipping over due to excessive movement speed and impact.
