Description

Technical Field

[0001] The utility model relates to the technical field of chain machines, in particular to an automatic flip chain machine for fire fighting. Background Art

[0002] With the rapid development of logistics technology, automated conveying equipment has been widely used in logistics centers, and conveying equipment often needs to cross fire doors. When a fire occurs, the fire doors cannot fall and close normally, resulting in the chain conveyor controlling the material conveying process. The chain conveyor guides the fire, causing the fire to spread further, thus posing a safety hazard.

[0003] Usually, when fire protection is carried out during material transportation, a fire shutter door is installed in the middle of the conveying device to isolate the fire area and extinguish the fire. However, in the event of a fire, the fire shutter door is falling. Since the gap between the two chain machines in front and behind the fire shutter door and the unpowered roller is usually small, the fire shutter door may get stuck on the conveying equipment and cannot fall to the ground normally for isolation. In addition, if a pallet of goods happens to pass by during the falling process of the fire shutter door, the fire shutter door will fall on the pallet of goods, thereby causing certain safety hazards and cargo losses. Therefore, we have proposed a fire-fighting automatic flip chain machine. Utility Model Content

[0004] In response to the shortcomings of the existing fire-fighting automatic flipping chain machine, the utility model provides an automatic flipping chain machine for fire-fighting, which has a flipping chain machine arranged between a first front chain machine and a second front chain machine. When a fire occurs, the flipping chain machine flips upward and provides a movement space for the fireproof rolling shutter door, thereby achieving the advantage of fire prevention and solving the problems raised in the above-mentioned background technology.

[0005] The utility model provides the following technical solutions: a fire-fighting automatic flipping chain machine, comprising a first front-end chain machine, a first bracket being installed at the lower end of the first front-end chain machine, a first chain being installed inside the first front-end chain machine through a first transmission shaft, a first sprocket being fixedly connected to the inner side of the first transmission shaft, a second sprocket being installed on the side of the first sprocket through a chain, a flipping chain machine being installed on the inner side of one end of the first front-end chain machine, a support column being fixedly connected between the two groups of the flipping chain machines, a helical gear being fixedly connected to the outside of the support column, a second front-end chain machine being placed on the other side of the flipping chain machine, a third chain being installed inside the second front-end chain machine, limit plates being installed on the inner sides of the first and second front-end chain machines, and auxiliary rollers being installed on the upper parts of the two groups of limit plates.

[0014] Compared with the existing fire-fighting automatic flip chain machine, the utility model has the following beneficial effects:

[0015] 1. The fire-fighting automatic flip chain machine is arranged between the first front chain machine and the second front chain machine through the flip chain machine, and a fire shutter door is installed on the upper end of the flip chain machine. When a fire occurs, the fire shutter door moves downward and triggers the photoelectric switch at the same time to control the first support plate to start. The first support plate drives the flip chain machine to flip. After the flip chain machine flips, an opening is formed between the first front chain machine and the second front chain machine. At the same time, the fire shutter door can move downward, and then isolate the two ends of the first front chain machine and the second front chain machine to prevent further spread of fire and reduce unnecessary losses when a fire occurs.

[0016] 2. The fire-fighting automatic flipping chain machine is arranged on the side of the first sprocket through the second sprocket, and the first sprocket and the second sprocket are connected by a chain. When the first chain rotates, the second transmission shaft can be driven to rotate synchronously through the first sprocket and the second sprocket, that is, when the first chain is controlled to rotate, the second chain can be driven to rotate synchronously, ensuring that when the flipping chain machine flips, the first chain and the second chain can maintain a uniform rotation state, ensuring stability when the material is moved, avoiding deviation in the speed, and causing dumping during material transportation.

[0017] 3. The fire-fighting automatic flip chain machine is equipped with photoelectric switches on the upper ends of the first front chain machine and the second front chain machine. When materials are placed on the upper part of the front chain machine, the photoelectric switches can be used to control the start of the equipment, that is, to ensure that the conveying device is started when there is material on the equipment, thereby improving resource utilization.

The third bracket 24 is installed at the lower end of the first front chain machine 1 and the second front chain machine 14. It is installed on the upper part of the first bracket 2 through the third bracket 24. The third bracket 24 limits the position of the second motor 21 and starts the second motor 21 at the same time.

At the same time, during the material conveying process carried by the first chain 4 and the second chain 9, the material conveying speed is ensured to remain uniform.

[0030] See also Figure 3 A first support plate 13 is installed on the side of the helical gear 11, and the lower end of the first support plate 13 is installed on the inner side of the first front chain machine 1 through the first motor 12.

At the same time, when the rolling door moves downward, it can move between the first front chain machine 1 and the second front chain machine 14, and at the same time start the function of isolating the fire source.

[0031] See also Figure 1 The first chain 4, the second chain 9 and the third chain 15 installed on the upper ends of the first front chain machine 1, the flip chain machine 7 and the second front chain machine 14 are kept at the same horizontal plane. At the same time, the materials to be conveyed are placed on the upper ends of the first chain 4, the second chain 9 and the third chain 15. They are kept at the same horizontal plane by the first chain 4, the second chain 9 and the third chain 15.

At the same time, the limit plate 23 assists in supporting the lower end of the material.

[0034] See also Figure 1 Photoelectric switches are installed on the upper parts of both ends of the first front chain machine 1 and the second front chain machine 14 and 2m above the upper end of the flip chain machine 7, and a fire shutter door is installed on the upper end of the flip chain machine 7. By installing photoelectric switches at both ends of the first front chain machine 1 and the second front chain machine 14, when materials are placed on the upper part of the first front chain machine 1, the photoelectric switches are blocked, that is, the two sets of second motors 21 are controlled to start, and the conveying device is driven to start at the same time, and the material can be controlled to be conveyed at the same time. At the same time, when a fire occurs, the fire shutter door receives a signal and controls the fire shutter door to move downward. At the same time, when the fire shutter door moves downward, the photoelectric switch 2m above the upper end of the flip chain machine 7 is blocked, that is, the first support plate 13 is controlled to start, and the first support plate 13 drives the flip chain machine 7 to flip. After the first support plate 13 drives the flip chain machine 7 to flip to the upper end, the fire shutter door can be moved to the ground at the same time, thereby blocking the space between the first front chain machine 1 and the second front chain machine 14, thereby preventing the spread of fire.

[0035] Working Principle: When in use, first, when cargo blocks the photoelectric switch while being transported on the first and second front chain conveyors 1 and 14, the photoelectric switch generates a pulse signal, which, through the PLC programmable controller, generates an output signal to energize the motor contactor coil. The motor rotation is activated by the second motor 21, which drives the first and third chains 4 and 15 to rotate, thus generating transport power for the material, transporting it to the reversing chain conveyor 7 and then to the third chain 15. In the event of a fire, the fire shutter door begins to descend. When it blocks the photoelectric switch located approximately 2 meters above the reversing chain conveyor 7, the photoelectric switch generates a pulse signal, which, through the PLC programmable controller, generates an output signal to energize the contactor coil of the first support plate 13. The first support plate 13 rotates, driving the support column 10, which in turn tilts the reversing chain conveyor 7 via the rotating device. When it touches the limit switch, the fire shutter door stops and returns to a vertical position. The fire shutter door can continue to descend until it reaches the ground. At the same time, when the fire shutter door blocks the photoelectric switch during the falling process, the pallet goods placed on the first front chain machine 1 and the second front chain machine 14 stop running.
