Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing technology, specifically a device for extinguishing fires in AGV (Automated Guided Vehicle) vehicles. Background Technology

[0002] AGVs are unmanned transport vehicles based on automatic navigation technology, widely used in logistics, manufacturing, mining and other fields. They mainly use technologies such as magnetic strips, laser navigation, visual positioning or QR code recognition to achieve path planning and environmental perception, and can operate flexibly without tracks to achieve automatic transport functions.

[0003] In the production of solar cells, AGVs are also widely used for automated handling. When silicon wafers are transferred from one process to the next, they are placed in storage baskets and then automatically transported by AGVs, replacing manual handling. This not only reduces labor costs but also improves handling efficiency.

[0004] AGVs are powered by lithium iron phosphate batteries. After prolonged and uninterrupted use, the batteries may age, become damaged, or deform, making them prone to malfunction and fire, and difficult to extinguish once ignited.

[0005] Therefore, a fire extinguishing device for AGV vehicles is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The device for extinguishing fires in AGV vehicles according to this utility model includes a frame; partitions are fixedly connected to the three sides and the top surface of the frame; casters are bolted to the four corners of the bottom surface of the frame; multiple hooks are provided on both sides of the bottom surface of the top partition; fire blankets are hung at the bottom of the multiple hooks; the side of the fire blanket is close to the inner side of the frame, and the side of the fire blanket hangs freely.

[0008] Preferably, multiple through holes are provided on both sides of the top partition; a hanging rope is slidably installed inside the through hole; the bottom end of the hanging rope is fixedly connected to the top end of the hook.

[0009] Preferably, the bottom of the frame and both sides away from the side where the partition is not installed are hinged with sleeve rods; an extension rod is slidably installed inside the sleeve rod; and a push rod is bolted between the ends of the two extension rods away from the sleeve rod.

[0010] Preferably, a collet is fixedly connected to one end of the sleeve rod near the extension rod; the extension rod slides through the middle of the collet; a conical cap is fitted around the outer ring of the extension rod; the conical cap is threadedly connected to the collet.

[0011] Preferably, a screw hole is provided in the middle of the top partition; a positioning sleeve is installed in the internal thread of the screw hole; a rod is inserted into the internal part of the positioning sleeve; a fixing ring is fixed to the top of the suspension rope; the fixing ring can be fitted onto the outer ring of the rod.

[0012] Preferably, a support plate is rotatably mounted on the bottom of the frame; the side of the support plate near the opening of the frame slides in contact with the ground.

[0013] Preferably, a horizontal plate is bolted to the center of the bottom surface of the support plate; ball joints are bolted to the top surfaces of both ends of the horizontal plate; a ball joint seat is rotatably mounted on the outer ring of the ball joint; a lead screw is bolted to the top of the ball joint seat; internally threaded inserts are fixed to the outer walls of the partitions on both sides; the outer ring of the lead screw is threadedly engaged with the inner ring of the internally threaded insert.

[0014] The advantages of this utility model are: 1. The device for extinguishing fires in AGV (Automated Guided Vehicle) trolleys as described in this utility model comprises a frame, partition, casters, hooks, and a fire blanket. When an AGV trolley experiences a battery fire due to a malfunction, the frame is moved to the location of the burning AGV trolley. The burning AGV trolley passes through an opening in the frame, which then surrounds it. The fire blanket is removed from the hook and allowed to fall freely inside the frame, covering the burning AGV trolley and preventing the fire from spreading, thus reducing losses. Simultaneously, the burning AGV trolley is isolated, preventing disruption to transport operations.

[0015] 2. The device for extinguishing fires in AGV vehicles according to this utility model comprises a support plate, a cross plate, a ball joint rod, a ball joint seat, a lead screw, and an internal threaded insert. The device pushes the frame so that the burning AGV vehicle passes through the opening in the frame and moves along the inclined support plate to the support plate. The lead screw is rotated in the opposite direction, causing it to rotate upwards, which in turn moves the ball joint seat upwards, pushing the ball joint rod upwards. Through the cross plate, the support plate rotates upwards to a horizontal position, lifting the burning AGV vehicle. The device then pushes the frame out of the workshop, carrying the burning AGV vehicle out of the workshop, thus preventing the burning AGV vehicle from causing a fire in the workshop.

[0019] 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 scope of protection of the present utility model.

[0020] like Figures 1 to 4As shown, a device for extinguishing fires in AGV vehicles includes a frame 1; partitions 2 are fixedly connected to three sides and the top surface of the frame 1; casters 3 are bolted to the four corners of the bottom surface of the frame 1; multiple hooks 4 are provided on both sides of the bottom surface of the top partition 2; fire blankets 5 are hung at the bottom of the multiple hooks 4; the side of the fire blanket 5 is close to the inner side of the frame 1, and the side of the fire blanket 5 hangs freely. Specifically, the frame 1 consists of two U-shaped steel frames and four square steel tubes; the two U-shaped steel frames are placed vertically aligned, and the four corners between the two U-shaped steel frames are supported and welded by square steel tubes; The partition 2 is a fireproof board. The partition 2 seals the three sides and the top of the frame 1, so that the opening and bottom of the U-shaped steel frame of the frame 1 are exposed, so that the frame 1 can be moved to the burning AGV and surrounded. When an AGV catches fire due to a battery malfunction, push the frame 1 to move the casters 3, causing the frame 1 to move to the burning AGV, so that one side opening of the frame 1 faces the burning AGV. Push the frame 1 again so that the burning AGV passes through the opening of the frame 1, and the frame 1 surrounds the burning AGV. At this time, remove the fire blanket 5 from the hook 4, allowing the fire blanket 5 to fall freely inside the frame 1, covering the burning AGV and thus preventing the fire from spreading and reducing the loss of the AGV. At the same time, the burning AGV is isolated to avoid affecting the handling work.

[0021] In some embodiments, such as Figures 1 to 4 As shown, multiple through holes 6 are provided on both sides of the top partition 2; a hanging rope 7 is slidably installed inside the through hole 6; the bottom end of the hanging rope 7 is fixedly connected to the top end of the hook 4. Specifically, the lifting rope 7 is a steel wire rope, and a screw head is fixed to the bottom end of the lifting rope 7; a connecting block 8 is rotatably installed on the top of the hook 4 through a bearing; the outer diameter of the connecting block 8 is larger than the diameter of the through hole 6; and a threaded hole matching the screw head is opened on the top of the connecting block 8. When not in use, the lifting rope 7 passes through the through hole 6 of the top partition 2 and is threaded into the threaded hole at the top of the connecting block 8 using the screw head at the bottom, so that the lifting rope 7 is fixedly connected to the connecting block 8. Pulling the lifting rope 7 through the through hole 6 and moving it upward will drive the connecting block 8 and the hook 4 to rise and move, so that the top surface of the connecting block 8 contacts the bottom surface of the top partition 2. After multiple lifting ropes 7 are gathered together, they are tied together to make each lifting rope 7 taut and fixed. Finally, the fire blanket 5 is hung on the hook 4. When in use, when the frame 1 is moved onto the burning AGV, the multiple ropes 7 that are fastened together are released, allowing the fire blanket 5 to fall freely inside the frame 1. This causes the hook 4 to move downwards, and the ropes 7 to pass through the through hole 6 and move downwards, so that the staff can release the fire blanket 5 from the outside of the frame 1, avoiding burns to the staff from the burning AGV and improving the safety of the staff. At the same time, it is easy to re-hoist the fire blanket 5 to the top of the frame 1 for reuse.

[0022] In some embodiments, such as Figures 1 to 6 As shown, sleeve rods 9 are hinged to both sides of the bottom of the frame 1 and the side away from the side where the partition 2 is not installed; extension rods 10 are slidably installed inside the sleeve rods 9; push rods 11 are bolted between the ends of the two extension rods 10 away from the sleeve rods 9. Specifically, multiple sets of threaded holes are provided on both sides of the U-shaped steel frame at the bottom of the frame 1 away from the opening. The hinge seat 12 is fixedly installed through the threaded holes and screws. The pivot block 13 is rotatably installed in the middle of the hinge seat 12 through the pivot rod, and the outer ring of the pivot rod is provided with a torsion spring; the sleeve rod 9 is fixedly connected to the pivot block 13. An extension rod 10 is fixedly connected to a ring at one end away from the sleeve rod 9. Both ends of the push rod 11 are fixedly connected to screws, and the screws pass through the ring. A nut is installed on the outer thread of the screw, and the ring and the push rod 11 are locked and fixed by the nut and the screw. When it is necessary to move the frame 1, pull the push rod 11 to cause the extension rod 10 to slide out from the inside of the sleeve rod 9. Then, pull the push rod 11 down to cause the extension rod 10 and the sleeve rod 9 to rotate, causing the rotating block 13 to rotate in the hinge seat 12. Push the push rod 11, and through the transmission of the extension rod 10, the sleeve rod 9, the rotating block 13 and the hinge seat 12, move the frame 1, which makes it easier for the staff to move the frame 1 and improves the convenience of the staff's operation.

[0023] Furthermore, such as Figures 5 to 6 As shown, a collet 14 is fixedly connected to one end of the sleeve rod 9 near the extension rod 10; the extension rod 10 slides through the middle of the collet 14; a conical cap 15 is sleeved on the outer ring of the extension rod 10; the conical cap 15 is threadedly connected to the collet 14. Specifically, the collet 14 has a cylindrical structure. A convex ring is fixed to the outer ring of the end of the collet 14 near the sleeve rod 9. The end of the collet 14 away from the sleeve rod 9 has a tapered structure. Multiple slots are opened around the end of the collet 14 away from the sleeve rod 9. The outer ring of the collet 14 has external threads. The inner ring of the cone cap 15 has internal threads, and the internal threads of the cone cap 15 match the external threads of the collet 14. When it is necessary to pull the extension rod 10 out of or retract it from the sleeve rod 9, rotate the cone cap 15 to separate the cone cap 15 from the chuck 14, so that the clamp 14 loosens its grip on the extension rod 10, allowing the extension rod 10 to slide along the sleeve rod 9, thus facilitating the pulling out and retraction of the extension rod 10. When it is necessary to fix and lock the extension rod 10 to the sleeve rod 9, rotate the cone cap 15 in the opposite direction so that the cone cap 15 moves along the external thread of the outer ring of the chuck 14 to the outer ring of the chuck 14. This causes the inner wall of the cone cap 15 to press against the conical outer wall of the chuck 14, causing the chuck 14 to bend inward and press against the outer wall of the extension rod 10, thus locking and fixing the extension rod 10 to the sleeve rod 9, thereby improving the stability during pushing.

[0024] Furthermore, such as Figures 1 to 4 As shown, a screw hole is provided in the middle of the top partition 2; a positioning sleeve 16 is installed in the internal thread of the screw hole; a rod 17 is inserted into the internal part of the positioning sleeve 16; a fixing ring 18 is fixed to the top end of the suspension rope 7; the fixing ring 18 can be fitted onto the outer ring of the rod 17. Specifically, the outer wall of the positioning sleeve 16 is threaded, the top outer ring of the positioning sleeve 16 is fixedly connected to an outer ring, and the middle part of the positioning sleeve 16 is provided with a insertion hole that matches the insertion rod 17. When not in use, pull the hoisting rope 7 to move the connecting block 8 and hook 4 upward, so that the top surface of the connecting block 8 contacts the bottom surface of the top partition 2; put the fixing rings 18 on the multiple hoisting ropes 7 onto the outer ring of the insert rod 17, so that each hoisting rope 7 is taut and fixed. In use, simply pull the plug 17 out of the socket of the positioning sleeve 16 to release multiple fixing rings 18 at the same time, so that multiple hanging ropes 7 are released at the same time, thereby causing multiple hooks 4 to fall at the same time, thus improving the stability of the fire blanket 5 falling.

[0025] In some embodiments, such as Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, a support plate 19 is rotatably mounted on the bottom of the frame 1; the side of the support plate 19 near the opening of the frame 1 slides in contact with the ground; a horizontal plate 20 is bolted to the middle of the bottom surface of the support plate 19; ball joint rods 21 are bolted to the top surfaces of both ends of the horizontal plate 20; a ball joint seat 22 is rotatably mounted on the outer ring of the ball joint rod 21; a lead screw 23 is bolted to the top of the ball joint seat 22; internally threaded inserts 24 are fixed to the outer walls of the partition plates 2 on both sides; the outer ring of the lead screw 23 is threadedly engaged with the inner ring of the internally threaded insert 24. Specifically, one end of the support plate 19 is rotatably mounted to the side of the U-shaped steel frame away from the opening of the frame 1 via a pivot, and the other end of the support plate 19 has an inclined surface at its bottom, which slides in contact with the ground; the middle part of the cross plate 20 is fixedly mounted to the middle of the bottom surface of the cross plate 20 using multiple countersunk screws; a ball groove is opened in the middle of the bottom surface of the ball head seat 22, and the ball head of the ball head rod 21 is set in the ball groove of the ball head seat 22; the middle of the internal thread insert 24 has an internal thread hole that matches the lead screw 23; When the AGV trolley catches fire due to a battery malfunction, the frame 1 is pushed to the AGV trolley, the lead screw 23 is rotated, and the internal threaded insert 24 is engaged, so that the lead screw 23 moves downward, driving the ball head seat 22 to rotate downward, pushing the ball head rod 21 to move downward, and through the drive of the cross plate 20, the support plate 19 rotates downward, so that the support plate 19 tilts to contact the ground. Then push the frame 1 so that the burning AGV passes through the opening of the frame 1 and moves along the inclined pallet 19 onto the pallet 19. At this time, rotate the lead screw 23 in the opposite direction so that the lead screw 23 rotates and moves upward, driving the ball head seat 22 to rotate and move upward, pushing the ball head rod 21 to move upward. Driven by the cross plate 20, the pallet 19 rotates upward to a horizontal state, lifting the burning AGV. Push the frame 1 out of the workshop and take the burning AGV out of the workshop, thus preventing the burning AGV from causing a fire in the workshop.

[0026] Working principle: When not in use, the hoisting rope 7 passes through the through hole 6 of the top partition 2 and is threaded into the threaded hole at the top of the connecting block 8 using the screw head at the bottom, so that the hoisting rope 7 is fixedly connected to the connecting block 8. Pulling the hoisting rope 7 through the through hole 6 and moving it upward will drive the connecting block 8 and the hook 4 to rise and move, so that the top surface of the connecting block 8 contacts the bottom surface of the top partition 2. The fixing rings 18 on the multiple hoisting ropes 7 are put on the outer ring of the plug rod 17, so that each hoisting rope 7 is taut and fixed. The fire blanket 5 is hung on the hook 4. When the AGV trolley catches fire due to a battery malfunction, pull the push rod 11 to cause the extension rod 10 to slide out from the inside of the sleeve rod 9. Then, pull the push rod 11 downward to cause the extension rod 10 and the sleeve rod 9 to rotate. This causes the rotating block 13 to rotate within the hinge seat 12. Rotate the cone cap 15 so that the cone cap 15 moves along the external thread of the outer ring of the chuck 14 to the outer ring of the chuck 14. This causes the inner wall of the cone cap 15 to press against the conical outer wall of the chuck 14, causing the chuck 14 to bend inward and press against the outer wall of the extension rod 10, thus locking and fixing the extension rod 10 to the sleeve rod 9. Push the frame 1 to move the caster wheel 3 so that the frame 1 moves to the location of the AGV trolley on fire, so that one side opening of the frame 1 faces the AGV trolley on fire. Rotating the lead screw 23, in conjunction with the internal thread insert 24, causes the lead screw 23 to move downward, which in turn causes the ball head seat 22 to rotate downward, pushing the ball head rod 21 downward. Through the action of the cross plate 20, the support plate 19 rotates downward, causing the support plate 19 to tilt and contact the ground. Then push the frame 1 so that the burning AGV trolley passes through the opening of the frame 1 and moves along the inclined pallet 19 onto the pallet 19; at this time, rotate the lead screw 23 in the opposite direction so that the lead screw 23 rotates and moves upward, driving the ball head seat 22 to rotate and move upward, pushing the ball head rod 21 to move upward, and through the action of the cross plate 20, causing the pallet 19 to rotate upward to a horizontal state, lifting the burning AGV trolley; at the same time, insert the rod 17 from the positioning sleeve 16. Pulling it out of the hole releases multiple fixing rings 18 simultaneously, causing multiple suspension ropes 7 to loosen at the same time. This allows the fire blanket 5 to fall freely inside the frame 1, covering the burning AGV. The frame 1 is then moved out of the workshop, taking the burning AGV out of the workshop and preventing it from causing a fire in the workshop. This prevents the fire from spreading and reduces the losses from the AGV fire. At the same time, the burning AGV is isolated, avoiding any impact on the handling operations.
