Description

Technical Field

[0001] This invention relates to the field of logistics transportation, and more specifically to a transportation system and method for traversing fire-prevention zones. Background Technology

[0002] To meet fire safety requirements, airport terminals are divided into multiple fire compartments. To satisfy both fire safety requirements and baggage handling operations, security doors and fire-resistant doors are installed at the junctions of adjacent fire compartments. Security doors are controlled by the baggage handling system and automatically close when the system stops operating to prevent intrusion by passengers or other personnel. Fire-resistant doors are managed by the fire department and their function is to prevent flames from passing through in the event of a fire. The conveyor equipment in the baggage handling system must pass through adjacent fire compartments, i.e., through both security doors and fire-resistant doors. In scenarios where the baggage handling system equipment at security isolation doors and fire-resistant partition doors is not designed to disconnect, meaning that both security isolation doors and fire-resistant partition doors descend onto the conveyor belt surface, the baggage handling system can only receive fire status commands from the fire protection system. This can easily lead to the fire-resistant partition door hitting the baggage surface when it falls, resulting in a failure to achieve complete isolation between the two fire compartments. Furthermore, only a fixed partition is installed below the conveyor equipment, which, while fulfilling the conveying function, cannot achieve complete isolation between the two fire compartments, thus posing a risk of flame spread during a fire.

[0003] Therefore, how to provide a conveying system and method for crossing fire compartments is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the present invention provides a conveying system and method for traversing fire compartments, aiming to solve the problem that complete isolation cannot be achieved between two fire compartments in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A conveying system that traverses fire compartments includes: a fire monitoring module, a fire-resistant partition door, a position detection component, a security management module, a security isolation door, and a conveyor.

[0007] The fire monitoring module is connected to the fire partition door, the position detection component and the security management module respectively. It is used to monitor the on-site situation, determine whether a fire alarm has occurred, and send the monitoring results to the security management module. When a fire occurs, it controls the fire partition door to close.

[0008] The first position detection component is connected to the security management module and is used to obtain the position information of the fire partition door. When the fire partition door descends to a preset position, the position information of the fire partition door is sent to the security management module.

[0009] The second position detection component is connected to the security management module and is used to detect whether there is luggage on the conveyor in the area below the fire partition door, and send the detection result to the security management module;

[0010] The security management module is used to receive the monitoring results and the detection results, and control the operation of the upstream conveyor and the security isolation door according to the monitoring results. When the monitoring result indicates that a fire has occurred, the upstream conveyor is controlled to stop conveying luggage to the current area conveyor. At the same time, the location information of the fire isolation door is obtained, and the current area conveyor is controlled to accelerate the delivery of luggage out of the fire isolation door area.

[0011] Preferably, it also includes a partition assembly, which includes an automatic lifting device and a fireproof partition panel, and is located below the conveyor in the current area; the security management module includes a partition assembly control unit;

[0012] The partition component control unit is connected to the automatic lifting device and is used to send control commands to the partition component in the event of a fire.

[0013] The automatic lifting device is used to control the fireproof partition to rise to the highest position and separate the space below the conveyor in the current area.

[0014] Preferably, the partition assembly further includes a partition panel bracket, and the fireproof partition panel is installed below the conveyor in the current area via the partition panel bracket.

[0015] Preferably, the conveyor includes a pallet, rollers, intermediate support rollers, side guards, and a belt;

[0016] The pallet, the roller, and the intermediate support roller are all mounted on the side guard plates and located between the two side guard plates. The roller is positioned below the pallet, the belt is sleeved around the outside of the pallet and the roller, and the intermediate support roller is positioned below the belt. The side guard plates are also provided with a pallet filling assembly and a frame gap filling assembly. The pallet filling assembly is positioned below the pallet, and the frame gap filling assembly is positioned below the outer surface of the belt. The belt passes between the pallet filling assembly and the frame gap filling assembly, and the pallet filling assembly is positioned at the corresponding position of the fireproof partition plate. When the fireproof partition plate is raised to its highest position, the top of the fireproof partition plate contacts the bottom of the pallet filling assembly.

[0017] Preferably, the security management module includes a fire fault detection unit;

[0018] The fire fault detection unit is connected to the position detection component and the fault handling unit respectively. After receiving the monitoring result that no fire has occurred, it sends a control command to the position detection component to detect the position of the fire partition door, and receives the position information of the fire partition door sent by the position detection component. If the fire partition door is detected to be in the conveyor channel of the current area conveyor, it sends a fault signal to the fire monitoring module. If it is not in the conveyor channel, it controls the security isolation door to open and controls the conveyor to start transporting luggage.

[0019] A method for transporting goods through fire compartments, comprising the following steps:

[0020] Monitor the scene to determine if a fire alarm has occurred. When a fire occurs, the fire isolation door is closed, and the upstream conveyor is stopped from transporting luggage to the current area conveyor. At the same time, it detects whether there is luggage on the area conveyor below the fire isolation door.

[0021] If there is luggage and the fire partition door is detected to have descended to a preset position, the current area conveyor is controlled to accelerate and send the luggage out of the fire partition door area.

[0022] Preferably, in the event of a fire, the fireproof partition is raised to its highest position to separate the space below the conveyor in the current area.

[0023] Preferably, when no fire occurs, the fire isolation door is in the open state. The system detects whether the fire isolation door is in the conveyor channel of the current area conveyor. If it is in the conveyor channel of the current area conveyor, a fault signal is sent. If it is not in the conveyor channel, the system controls the security isolation door to open and controls the conveyor to start transporting luggage.

[0024] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a conveyor system and method for traversing fire compartments. In the event of a fire, it can quickly convey luggage out of the fire compartment door area, thereby eliminating the risk that the luggage descends to the upper surface of the luggage instead of the conveyor belt surface when the fire compartment door is closed, causing two adjacent fire compartments to not be completely separated. In addition, by setting up a partition component, the present invention can completely close the area below the conveyor tray in the event of a fire, thereby achieving complete separation of two adjacent fire compartments, eliminating the risk of flames spreading between two adjacent fire compartments, and providing protection for airport property and personal safety.

Detailed Implementation

[0031] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention discloses a conveying system for traversing fire compartments, comprising: a fire monitoring module, a fire-resistant partition door 6, a position detection component, a security management module, a security isolation door 4, and a conveyor.

[0033] The fire monitoring module is connected to the fire partition door 6, the position detection component and the security management module respectively. It is used to monitor the on-site situation, determine whether a fire alarm has occurred, and send the monitoring results to the security management module. When a fire occurs, it controls the fire partition door 6 to close.

[0034] The first position detection component 5 is connected to the security management module and is used to obtain the position information of the fire partition door 6. When the fire partition door 6 descends to the preset position, the position information of the fire partition door 6 is sent to the security management module.

[0035] The second position detection component is connected to the security management module and is used to detect whether there is luggage 7 on the conveyor in the area below the fire partition door 6, and send the detection results to the security management module.

[0036] The security management module is used to receive monitoring and detection results, and control the operation of the upstream conveyor 9 and security isolation door 4 according to the monitoring results. When the monitoring result indicates that a fire has occurred, the upstream conveyor 9 is controlled to stop conveying luggage 7 to the current area conveyor 1. At the same time, the position information of the fire isolation door 6 is obtained, and the current area conveyor 1 is controlled to accelerate the delivery of luggage 7 out of the fire isolation door 6 area.

[0037] To further implement the above technical solution, a partition component 2 is also included. The partition component 2 includes an automatic lifting device 20 and a fireproof partition panel 17, which is located below the current area conveyor 1. The security management module includes a control unit for the partition component 2.

[0038] The control unit of the partition assembly 2 is connected to the automatic lifting device 20 and is used to send control commands to the partition assembly 2 in the event of a fire.

[0039] Automatic lifting device 20 is used to control the fireproof partition 17 to rise to the highest position and separate the space below the current area conveyor 1.

[0040] In this embodiment, the automatic lifting device 20 can be any device that achieves automatic lifting, such as a pneumatic device or an electric device.

[0041] To further implement the above technical solution, the partition assembly 2 also includes a partition plate bracket 18, through which the fireproof partition plate 17 is installed below the current area conveyor 1.

[0042] To further implement the above technical solution, the conveyor includes a pallet 12, a roller 14, an intermediate support roller 15, a side guard plate 10, and a belt 13;

[0043] The pallet 12, roller 14, and intermediate support roller 15 are all installed on the side guard plate 10 and located between the two side guard plates 10. The roller 14 is located below the pallet 12, the belt 13 is sleeved on the outside of the pallet 12 and the roller 14, and the intermediate support roller 15 is located below the belt 13. The side guard plate 10 is also provided with a pallet filling assembly 11 and a frame gap filling assembly 1616. The pallet filling assembly 11 is located below the pallet 12, and the frame gap filling assembly 1616 is located below the outer surface of the belt 13. The belt 13 passes between the pallet filling assembly 11 and the frame gap filling assembly 1616. The pallet filling assembly 11 is located at the corresponding position of the fireproof partition plate 17. When the fireproof partition plate 17 rises to the highest position, the top of the fireproof partition plate 17 contacts the bottom of the pallet filling assembly 11.

[0044] In this embodiment, the conveyor is mounted on the support leg 19. When no fire occurs, the fireproof partition 17 is located at the lowest end, which does not affect the passage space of the belt 13 between the pallet filling assembly 11 and the frame gap filling assembly 16. When a fire occurs, when the fireproof partition 17 rises to the highest state, its top end is in close contact with the pallet filling assembly 11, closing the passage space of the belt 13 between the pallet filling assembly 11 and the frame gap filling assembly 16, thereby eliminating the gap between fire compartment one and fire compartment two.

[0045] To further implement the above technical solutions, the security management module includes a fire fault detection unit;

[0046] The fire fault detection unit is connected to the position detection component and the fault handling unit respectively. After receiving the monitoring result that no fire has occurred, it sends a control command to the position detection component to detect the position of the fire partition door 6, and receives the position information of the fire partition door 6 sent by the position detection component. If the fire partition door 6 is detected to be in the conveying channel of the current area conveyor 1, a fault signal is sent to the fire monitoring module. If it is not in the conveying channel, the security isolation door 4 is opened and the conveyor is started to transport the luggage 7.

[0047] In this embodiment, the security management module is an industrial control computer, and the installation locations of each part are shown in the diagram. Figure 1-2 As shown, the conveyor, partition assembly 2, position detection assembly, security isolation door 4, fire isolation door 6, and upstream conveyor 9 and downstream conveyor 8 in the attached diagram are installed on building 3 or other installation platform (not shown in the diagram) in the positions shown in the diagram.

[0048] A method for transporting goods across fire compartments, such as Figure 3 As shown, it includes the following steps:

[0049] Monitor the scene to determine if a fire alarm has occurred. When a fire occurs, the fire isolation door 6 is closed, and the upstream conveyor 9 is controlled to stop conveying luggage 7 to the current area conveyor 1. At the same time, it checks whether there is luggage 7 on the area conveyor below the fire isolation door 6.

[0050] If there is luggage 7 and the fire partition door 6 is detected to have descended to the preset position, the current area conveyor 1 is controlled to accelerate and send the luggage 7 out of the fire partition door 6 area.

[0051] To further implement the above technical solution, when a fire occurs, the fireproof partition 17 is raised to its highest position to separate the space below the conveyor 1 in the current area.

[0052] To further implement the above technical solution, when there is no fire, the fire isolation door 6 is in the open state. It is detected whether the fire isolation door 6 is in the conveying channel of the current area conveyor 1. If it is in the conveying channel of the current area conveyor 1, a fault signal is sent. If it is not in the conveying channel, the security isolation door 4 is opened and the conveyor is started to transport the luggage 7.
