Description

Technical Field

[0001] This invention relates to the field of chain machine technology, specifically to an automatic fire-fighting rotating chain machine. Background Technology

[0002] With the rapid development of logistics technology, automated conveying equipment is widely used in logistics centers. However, these conveying devices often need to cross fire doors. In the event of a fire, the fire doors may fail to close properly, causing the chain conveyor to guide the fire during material transport, leading to the further spread of the fire and creating a safety hazard.

[0003] Typically, fire-resistant roller shutters are installed in the middle of the conveyor to isolate the fire area during fire prevention and control. However, during a fire, the gaps between the front and rear chain conveyors and the non-powered rollers are usually small, which can cause the fire-resistant roller shutter to get stuck on the conveyor and prevent it from landing properly on the ground for isolation. In addition, if palletized goods happen to be passing by during the descent, the fire-resistant roller shutter may fall on the palletized goods, causing certain safety hazards and loss of goods. Therefore, we propose an automatic fire-fighting tilting chain conveyor. Summary of the Invention

[0004] To address the shortcomings of existing automatic fire-fighting rotating chain machines, this invention provides an automatic fire-fighting rotating chain machine, which features a rotating chain machine positioned between two front-end chain machines. In the event of a fire, the rotating chain machine rotates upward, providing movement space for the fireproof rolling shutter door and thus achieving the advantage of fire prevention, thereby solving the problems mentioned in the background art.

[0005] This invention provides the following technical solution: an automatic fire-fighting rotating chain machine, comprising a front-end chain machine, a first bracket installed at the lower end of the front-end chain machine, a first chain installed inside the front-end chain machine via a first drive shaft, a first sprocket fixedly connected to the inner side of the first drive shaft, a second sprocket installed on the side of the first sprocket via a chain, a rotating chain machine installed inside one end of the front-end chain machine, a support column fixedly connected between the two sets of rotating chain machines, a helical gear fixedly connected to the outside of the support column, a front-end chain machine placed on the other side of the rotating chain machine, a third chain installed inside the front-end chain machine, limit plates installed on the inner sides of both the front-end chain machine and the front-end chain machine, and auxiliary rollers installed on the upper part of the two sets of limit plates.

[0006] Preferably, a connecting shaft is fixedly connected to the middle of the first drive shaft, and a gear is fixedly connected to the outside of the connecting shaft. A second motor is mounted on the lower end of the gear via a toothed chain. The second motor is mounted on the upper part of the first bracket via a third bracket. A third bracket is mounted on both the front chain machine and the lower end of the front chain machine.

[0007] Preferably, the first sprocket is disposed inside the first drive shaft, and the front chain extends to the side of the tilting chain.

[0008] Preferably, the inside of the flipping chain machine is equipped with a second chain via a second transmission shaft, and one end of the second sprocket is fixedly connected to the second transmission shaft.

[0009] Preferably, a first support plate is meshed on the side of the helical gear, and the lower end of the first support plate is mounted on the inner side of the front chain machine via a first motor.

[0010] Preferably, the front-end chain machine, the tilting chain machine, and the first, second, and third chains installed on the upper end of the front-end chain machine are kept on the same horizontal plane, and the material to be conveyed is placed on the upper end of the first, second, and third chains.

[0011] Preferably, a second support plate is installed on the inner side of the front chain machine at the lower part of one end of the flip chain machine, and a second bracket is fixedly connected to the lower side of the end of the flip chain machine, with the second bracket placed on the upper part of the second support plate.

[0012] Preferably, the auxiliary roller is sleeved inside the front chain machine, and the auxiliary roller is positioned at the upper end of the limiting plate.

[0013] Preferably, photoelectric switches are installed at the upper part of the front chain machine and both ends of the front chain machine and at 2m above the top of the tilting chain machine, and a fireproof roller shutter door is installed at the top of the tilting chain machine.

[0014] Compared with existing automatic fire-fighting tilting chain machines, the present invention has the following advantages:

[0015] 1. This fire-fighting automatic tilting chain conveyor is installed between two front-end chain conveyors, with a fireproof rolling shutter door installed at the top of the tilting chain conveyor. In the event of a fire, the fireproof rolling shutter door moves downward, triggering a photoelectric switch to activate the first support plate. The first support plate drives the tilting chain conveyor to tilt, creating an opening between the two front-end chain conveyors. Simultaneously, the fireproof rolling shutter door can move downward, thus isolating both ends of the front-end chain conveyor to prevent further spread of fire and reduce unnecessary losses.

[0016] 2. This fire-fighting automatic tilting chain machine has a second sprocket mounted on the side of the first sprocket, and the first and second sprockets are connected by a chain. When the first chain rotates, the first and second sprockets can drive the second transmission shaft to rotate synchronously. That is, controlling the rotation of the first chain can drive the second chain to rotate synchronously, ensuring that the first and second chains maintain a uniform rotation speed when the tilting chain machine is tilting, ensuring the stability of material movement, avoiding deviations in rotation speed, and preventing tipping of materials during conveying.

[0017] 3. This fire-fighting automatic tilting chain conveyor is equipped with photoelectric switches installed at the front chain conveyor and its upper end. When material is placed on the upper part of the front chain conveyor, the photoelectric switches can control the equipment to start, ensuring that the conveying device starts when there is material on the equipment, thereby improving resource utilization.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An automatic fire-fighting tilting chain conveyor includes a front chain conveyor 1. A first support 2 is mounted at the lower end of the front chain conveyor 1, supporting its position. A first chain 4 is mounted inside the front chain conveyor 1 via a first drive shaft 3. When the first chain 4 rotates, it can transport palletized goods. A first sprocket 5 is fixedly connected to the inner side of the first drive shaft 3. A second sprocket 6 is mounted on the side of the first sprocket 5 via a chain. The first drive shaft 3 drives the first sprocket 5 to rotate, and the first sprocket 5 drives the second sprocket 6 to rotate synchronously, thereby driving the second chain 9 to rotate synchronously. A tilting mechanism is mounted on the inner side of one end of the front chain conveyor 1. The rotating chain machine 7 has a support column 10 fixedly connected between two sets of rotating chain machines 7. When the support column 10 rotates, it drives the rotating chain machine 7 to rotate. A helical gear 11 is fixedly connected to the outside of the support column 10. A front chain machine 14 is placed on the other side of the rotating chain machine 7. A third chain 15 is installed inside the front chain machine 14. The front chain machine 1, rotating chain machine 7 and front chain machine 14 drive the material to be conveyed. Limit plates 23 are installed on the inside of the front chain machine 1 and the front chain machine 14. Auxiliary rollers 22 are installed on the upper part of the two sets of limit plates 23. The limit plates 23 help to support the conveyed material.

[0027] Please see Figure 2 A connecting shaft 18 is fixedly connected to the middle of the first drive shaft 3. A gear 19 is fixedly connected to the outside of the connecting shaft 18. A second motor 21 is mounted on the lower end of the gear 19 via a toothed chain 20. The second motor 21 is mounted on the upper part of the first support 2 via a third bracket 24. A third bracket 24 is mounted on the lower end of both the front chain machine 1 and the front chain machine 14. The third bracket 24 is mounted on the upper part of the first support 2 and limits the position of the second motor 21. When the second motor 21 is started, the second motor 21 drives the gear 19 to rotate via the toothed chain 20. The gear 19 drives the first chain 4 and the third chain 15 to rotate via the connecting shaft 18. When the first chain 4 and the third chain 15 rotate, they can push materials for transmission.

[0028] Please see Figure 5The first sprocket 5 is located inside the first drive shaft 3, and the front chain machine 1 extends to the side of the tilting chain machine 7. The first chain 4 and the second chain 9 are staggered, which facilitates the material to be pushed to the upper part of the tilting chain machine 7 by the first chain 4. At the same time, the second chain 9 installed at the upper end of the tilting chain machine 7 can drive the material to be conveyed to the other side.

[0029] Please see Figure 3 and Figure 5 The inside of the tilting chain machine 7 is equipped with a second chain 9 via a second transmission shaft 8. One end of the second sprocket 6 is fixedly connected to the second transmission shaft 8. When the first chain 4 rotates, it drives the first transmission shaft 3 to rotate, which in turn drives the first sprocket 5 to rotate synchronously. The first sprocket 5 then drives the second sprocket 6 to rotate via the chain. In other words, when the first chain 4 rotates, it can drive the second chain 9 to rotate synchronously through the linkage, ensuring that the conveying speed of the first chain 4 and the second chain 9 remains the same. At the same time, during the material conveying process, the first chain 4 and the second chain 9 ensure that the material conveying speed remains uniform.

[0030] Please see Figure 3 The helical gear 11 is meshed with a first support plate 13. The lower end of the first support plate 13 is installed inside the front chain machine 1 via the first motor 12. By starting the first support plate 13, the first support plate 13 controls the gear and the helical gear 11 to mesh with each other. That is, during the process of starting the first support plate 13, the other end of the rotating chain machine 7 can be driven to rotate upward. At the same time, when the roller shutter door moves downward, it can move between the front chain machine 1 and the front chain machine 14, and at the same time activate the function of isolating the fire source.

[0031] Please see Figure 1 The first chain 4, the second chain 9, and the third chain 15 installed on the upper end of the front-end chain machine 1, the tilting chain machine 7, and the front-end chain machine 14 are kept on the same horizontal plane. At the same time, the material to be conveyed is placed on the upper end of the first chain 4, the second chain 9, and the third chain 15. By keeping the first chain 4, the second chain 9, and the third chain 15 on the same horizontal plane, and by moving the material with the first chain 4, the second chain 9, and the third chain 15, the stability of its transfer can be improved.

[0032] Please see Figure 2A second support plate 17 is installed on the lower part of one end of the flipping chain machine 7 on the inner side of the front chain machine 14. A second bracket 16 is fixedly connected to the lower side of the end of the flipping chain machine 7. The second bracket 16 is placed on the upper part of the second support plate 17. When the flipping chain machine 7 is kept horizontal with the front chain machine 1 by installing the second bracket 16 on the lower part of the other end of the flipping chain machine 7, the second bracket 16 installed at the front end of the flipping chain machine 7 is sleeved on the upper part of the second support plate 17, that is, the second support plate 17 improves the support of the other end of the flipping chain machine 7.

[0033] Please see Figure 6 The auxiliary roller 22 is sleeved inside the front chain machine 14, and is also located on the upper end of the limiting plate 23. The limiting plate 23 is installed on the inner side of the front chain machine 1 and the front chain machine 14, and is snapped into the inner side of the front chain machine 1 and the front chain machine 14. The auxiliary roller 22 is installed on the upper part of the limiting plate 23. The auxiliary roller 22 limits the position of the limiting plate 23, improves the stability of the limiting plate 23 during installation, and the limiting plate 23 assists in supporting the lower end of the material.

[0034] Please see Figure 1 Photoelectric switches are installed at the upper parts of both ends of the front chain conveyor 1 and front chain conveyor 14, and 2m above the top of the tilting chain conveyor 7. A fireproof roller shutter door is installed at the top of the tilting chain conveyor 7. By installing photoelectric switches at both ends of the front chain conveyor 1 and front chain conveyor 14, when material is placed on the upper part of the front chain conveyor 1, the photoelectric switch is blocked, which controls the two sets of second motors 21 to start, and simultaneously drives the conveying device to start, and controls the material to be conveyed. At the same time, when a fire occurs, the fireproof roller shutter door receives a signal and controls the fireproof roller shutter door to move downward. When the fireproof roller shutter door moves downward, it will be blocked by the photoelectric switch located 2m above the top of the tilting chain conveyor 7, which controls the first support plate 13 to start. The first support plate 13 drives the tilting chain conveyor 7 to tilt. After the first support plate 13 drives the tilting chain conveyor 7 to tilt to the top, the fireproof roller shutter door can move to the ground. Thus, it blocks the front chain conveyor 1 and front chain conveyor 14, thereby preventing the spread of fire.

[0035] Working Principle: In operation, when goods are transported on the front chain conveyor 1 and front chain conveyor 14 and block the photoelectric switch, the photoelectric switch generates a pulse signal. This pulse signal is output by the PLC programmable controller to energize the motor contactor coil, causing the motor to rotate. This starts the second motor 21, which in turn drives the first chain 4 and the third chain 15 to rotate, thus providing transport power for the materials. The materials are then transported to the tilting chain conveyor 7 and then to the third chain 15. In the event of a fire, the fireproof roller shutter door begins to fall. When it blocks the photoelectric switch located approximately 2 meters above the tilting chain conveyor 7, the photoelectric switch generates a pulse signal. This pulse signal is output by the PLC programmable controller to energize the contactor coil of the first support plate 13. The first support plate 13 rotates, causing the support column 10 to rotate. This rotation device flips the tilting chain conveyor 7. When it touches the limit switch, it stops and becomes vertical. The fireproof roller shutter door can then continue to fall until it reaches the ground. At the same time, when the fireproof rolling shutter door blocks the photoelectric switch during its descent, the palletized goods placed on the front chain machine 1 and the front chain machine 14 stop running.
