Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of AGV safety, in particular to a pedal-type AGV fire-fighting vehicle. Background Art
[0002] AGVs, or automated guided vehicles, are unmanned, automated vehicles equipped with electromagnetic or optical guidance systems, enabling them to travel along a prescribed path and offering safety protection and various transfer functions.
[0003] Currently, AGVs on the market generally use lithium batteries as their power source. However, lithium batteries pose certain safety risks during long-term AGV operation. When a lithium battery short-circuits, it generates high temperatures, causing the separators within the internal battery cells to melt. This melting process can further trigger internal short circuits, generating even more heat. This accumulated and mutually reinforcing heat can eventually rupture the battery cell's explosion-proof membrane, causing the electrolyte to spray out, potentially leading to combustion and fire.
[0004] Lithium battery fires are particularly troublesome: they ignite extremely quickly, burn at extremely high temperatures, and most of the combustion reaction occurs inside the battery casing, making firefighting extremely difficult. Traditional gas and dry powder fire extinguishers are often ineffective in combating lithium battery fires. While dry powder fire extinguishers can quickly extinguish open flames, they cannot effectively reduce the internal temperature of the lithium battery, causing internal chemical reactions to continue, making it easy for the battery to reignite or even explode. Using large amounts of fire water to cool the battery is more effective because water can effectively absorb and disperse the heat generated by the battery, reducing the temperature of the fire source and thus controlling the spread of the fire.
[0005] Therefore, in view of the safety issues of AGV lithium batteries, a pedal-type AGV fire-fighting vehicle is designed to solve the above problems. Utility Model Content
[0006] The utility model provides a pedal-type AGV fire-fighting vehicle, which solves the above-mentioned technical problems.
[0007] In order to solve the above technical problems, the utility model provides a pedal-type AGV fire-fighting trolley, including a trolley fire-fighting hood, guide rails are fixed on both sides of the bottom of the trolley fire-fighting hood, four wheels are connected to the rotating shafts of the guide rails on both sides, a water pipe is fixedly connected to the middle part of the top of the trolley fire-fighting hood, a push rod is fixed at an angle on the upper part of the tail end of the trolley fire-fighting hood, an opening is opened at the head end, and a flip door is hinged at the opening, a support rod is fixed on the top of the head end, a guide ring is fixed on the support rod, and a guide ring is also fixed to the middle part of the top of the push rod, a steel wire rope is passed through the two guide rings, and one end of the steel wire rope is fixedly connected to the lower middle part of the flip door.
[0008] Preferably, the external port of the water pipe is provided with a KD65 interface to be connected to an external standard fire hose.
[0009] Preferably, a pedal rod is fixed obliquely at the lower part of the tail end of the trolley fire extinguishing hood, and stepping on the pedal rod can tilt up the lever of the trolley fire extinguishing hood.
[0010] Preferably, sealing strips are fixed to the guide rails on both sides of the bottom displacement of the trolley fire extinguishing cover.
[0011] Compared with related technologies, the pedal-type AGV fire-fighting vehicle provided by the present invention has the following beneficial effects:
[0012] The utility model provides that when the lithium battery of the AGV catches fire, the staff can push the fire extinguishing trolley device alone and move it quickly to the burning AGV, so that the trolley fire extinguishing cover covers the burning AGV to enclose the burning AGV, forming a water pool for protection to prevent the spread of fire. The fire extinguishing trolley is then pushed to drive the burning AGV to move quickly to an open area. By providing a handle, personnel are protected away from the burning AGV, and the protection capability is enhanced. Then, through the KD65 interface of the water pipe, a standard fire hose is quickly connected to input water into the trolley fire extinguishing cover to cool down the burning AGV and extinguish the fire, thereby having high safety and protection.

[0017] Embodiment 1, by Figure 1-3 A pedal-type AGV fire-fighting trolley is given, including a trolley fire-fighting hood 1, guide rails are fixed on both sides of the bottom of the trolley fire-fighting hood 1, and four wheels 5 are connected to the rotating shafts of the guide rails on both sides. A water pipe 2 is fixed to the top middle of the trolley fire-fighting hood 1, and a push rod 3 is fixed obliquely on the upper part of the tail end of the trolley fire-fighting hood 1. An opening is opened at the head end of 1, and a flip door 8 is hinged at the opening. A support rod is fixed on the top of the head end of 1, and a guide ring 6 is fixed on the support rod, and a guide ring 6 is also fixed on the top middle of the push rod 3. A steel wire rope 7 is inserted into the two guide rings 6, and one end of the steel wire rope 7 is fixedly connected to the lower middle part of the flip door 8.
[0018] Specifically, when the lithium battery of the AGV catches fire, the staff can grab the push rod 3, push the AGV fire extinguishing trolley through the wheels 5, quickly move it to the side of the AGV and align it with it. The burning AGV contacts and pushes the flip door 8, driving the flip door 8 to flip upward through the hinge to open the opening inside the trolley fire extinguishing cover 1, so that the burning AGV enters the interior. After the burning AGV is completely inside the trolley fire extinguishing cover 1, there is no need to contact the flip door 8. The flip door 8 automatically closes the opening downward under gravity, sealing the burning AGV inside. A water pool is formed to protect the fire from spreading. The staff then pushes the fire-fighting trolley to drive the AGV on fire to move quickly to an open area. Through the KD65 interface of the water pipe 2, the standard fire hose is quickly connected to input the water into the trolley fire extinguishing cover 1 to cool down the AGV on fire and extinguish the fire. It has high safety and protection. When taking out the AGV for cooling and extinguishing the fire, pull the wire rope 7 next to the push rod 3, which is guided by two guide rings to drive the flip door 8 to flip outward and upward to open the opening. Then pull the device back to move, and the AGV will leave the trolley fire extinguishing cover 1.
[0019] Among them, the external port of the water pipe 2 adopts a KD65 interface setting, which is connected to an external standard fire hose; the water is input into the trolley fire extinguishing cover 1 to cool down the burning AVG and extinguish the fire, which has high safety and protection.
[0020] Example 2: Based on Example 1, a pedal rod 4 is fixed obliquely at the lower part of the tail end of the trolley fire extinguishing hood 1, and stepping on the pedal rod 4 can lift the lever of the trolley fire extinguishing hood 1; when the lever of the trolley fire extinguishing hood 1 is lifted, the trolley fire extinguishing hood 1 is pushed to move above the AGV, and the foot is separated from the pedal rod 4, and the trolley fire extinguishing hood 1 covers the burning AGV to enclose the burning AGV therein, forming a water pool for protection to prevent the fire from spreading.
[0021] Among them, sealing strips 11 are fixed to the guide rails on both sides of the bottom displacement of the trolley fire extinguishing cover 1. When the trolley fire extinguishing cover 1 moves, the sealing strips 11 at the bottom are in contact with the ground to increase the sealing performance.
