Description

Technical Field

[0001] This invention relates to the field of suspended conveyors, and more particularly to a dual-purpose suspended conveyor for both cargo transport and firefighting, and its method of use. Background Technology

[0002] Suspended conveyors are conveying machines that use overhead tracks at the installation location, with a pulley structure supporting the suspended structure as it moves along the overhead tracks. They are particularly suitable for use in factories and workshops with dense internal machinery and materials, as well as indoor freight yards. Their running trajectory is determined by the location of the suspended tracks, enabling point-to-point transfer. This avoids the problems of ground-based transfer methods, such as being easily blocked by obstacles and having low efficiency. Furthermore, it makes full use of the internal space of factories and workshops, making it suitable for widespread use.

[0003] However, current suspended conveyors can only handle cargo transfer. Industrial plants have a larger floor area and more equipment than other indoor buildings. In particular, workshops equipped with suspended conveyors can solve the problem of inconvenient ground transportation and make fuller use of the factory floor space. However, this also leads to the problem that, since there is no need to set up ground transportation channels, equipment and goods can be stacked more densely on the ground. When a fire occurs in the factory, it will undoubtedly increase the difficulty of fire fighting and personnel escape. Especially when a large area of ​​the factory is on fire, if the trapped personnel cannot open up a ground escape route, property damage and casualties are very likely to occur.

[0004] Therefore, it is necessary to provide a dual-purpose overhead conveyor for both cargo transport and fire extinguishing, and its usage method, to solve the above-mentioned technical problems. Summary of the Invention

[0018] A method for using a dual-purpose overhead conveyor for both cargo transport and firefighting includes the following steps:

[0019] S1. In daily use, it is used as a rail-mounted freight device. The entire structure below is supported by the rail wheels of the carriage and moves along the installation direction of the rail. When it is necessary to load goods, the traction motor drives the drive shaft and drive gear to rotate. The drive gear meshes with the transmission gear to drive the upper winding shaft to rotate, so as to unfold the four load-bearing steel cables that are arranged at the four corners of the auxiliary plate and the pressure plate downward. Then, the auxiliary plate and the pressure plate fall down between the two sets of enclosures at the same time. As the lower winding shaft moves down with the auxiliary plate, the split steel cable, long air pipe and water supply branch pipe wound on the outside of the lower winding shaft are simultaneously pulled vertically and unfolded.

[0020] S2. When the split steel cable is fully extended, the upper and lower ends of the split steel cable are connected to the top cover and the lower roller respectively. At this time, the lower roller and the auxiliary plate cannot continue to move down, while the load-bearing steel cable with a length greater than the split steel cable continues to extend to ensure that the pressure plate is separated from the auxiliary plate. The pressure plate continues to move down and uses the top side of the pressure plate as a cargo placement platform to realize the cargo transportation function.

[0021] S3. When a fire occurs in the factory, the slide will move the entire structure below along the hanging rail to the position of the traction machine. Under normal conditions, ensure that the two sets of sealing joints at both ends of the core tube of the traction machine are connected to the water pump and the air pump respectively. When the slide's drag plate supports the two sets of pipe joints to the position of the traction machine, the slide will move the pipe joints to the outside of the two sets of extension pipes inside the traction machine. By moving to the end of the track, the pipe joints can be inserted into the insertion pipe outside the quick-release seat. At the same time, the torsion spring support arm will clamp and lock the pipe joints to the outside, thereby realizing the quick connection of the two extension pipes to the main water supply pipe and the long air pipe.

[0022] S4. Then, the water and gas circuits are connected through the two sets of pipe joints in the top drag plate of the carriage, and the carriage is moved to the required fire extinguishing position along the hanging rail. At the same time, the core tube is driven to rotate by the servo motor to loosen the winding and tightening state of the extension tube. Thus, the two extension tubes are pulled along the hanging rail by the two sets of pipe joints until the carriage moves to the required fire extinguishing position. Then, the fire extinguishing water is sent to the water distribution pipe on the bottom side of the auxiliary plate through the external water pump in sequence along the core tube, extension tube, pipe joint, water supply main pipe, water supply branch pipe, lower reel and conduit. The fire extinguishing water is sprayed downward through the spray holes on the bottom side of the water distribution pipe.

[0023] S5. When burning materials on the ground at the fire scene obstruct people's escape, follow the steps above to open the water and gas lines, and separate the auxiliary plate and the pressure plate. At the same time, spray water downwards through the bottom nozzles of the rectangular water distribution pipe on the bottom side of the auxiliary plate to form a four-sided water curtain between the auxiliary plate and the pressure plate. The four-sided water curtain, the top auxiliary plate, and the bottom pressure plate form a rescue space. The pressure plate in its lowered state serves as a rescue platform. People stand on the surface of the pressure plate and use the suspended rail to walk across the fire ground. At the same time, air is supplied to the pipe joint, long air pipe, lower reel, and short air pipe through an extension pipe connected to the air pump. Clean air is then introduced into the rescue space through the diffuser connected to the short air pipe to maintain a positive pressure state in the rescue space and provide breathing support to the people being rescued in the burning area.

[0090] A method for using a dual-purpose overhead conveyor for both cargo transport and firefighting includes the following steps:

[0091] S1. In daily use, it is used as a rail-mounted freight device. The overall structure below is supported by the rail wheels 102 of the carriage 1 and moves along the installation direction of the rail 2. When it is necessary to load goods, the traction motor 103 drives the drive shaft 105 and drive gear 106 to rotate. The drive gear 106 meshes with the transmission gear 702 to drive the upper winding shaft 7 to rotate, so as to unfold the four load-bearing steel cables 10, which are arranged at the four corners of the auxiliary plate 6 and the pressure plate 5, downward. Then, the auxiliary plate 6 and the pressure plate 5 fall down between the two sets of surrounding plates 3 at the same time. As the lower winding shaft 8 moves down with the auxiliary plate 6, the split steel cable 12, the long air pipe 13 and the water supply branch pipe 11 wound on the outside of the lower winding shaft 8 are pulled vertically and unfolded at the same time.

[0092] S2. When the split steel cable 12 is fully extended, the upper and lower ends of the split steel cable 12 are connected to the top cover 4 and the lower roller 8 respectively. At this time, the lower roller 8 and the auxiliary plate 6 cannot continue to move down, while the load-bearing steel cable 10, which is longer than the split steel cable 12, continues to extend to ensure that the pressure plate 5 is separated from the auxiliary plate 6. The pressure plate 5 continues to move down, and the top side of the pressure plate 5 is used as a cargo placement platform to realize the cargo transportation function.

[0093] S3. When a fire occurs in the factory, the slide 1 drives the entire structure below to move along the hanging rail 2 to the position of the traction machine 14. Under normal conditions, ensure that the two sets of sealing joints 14d at both ends of the core tube 14b of the traction machine 14 are connected to the water pump and the air pump respectively. When the drag plate 109 of the slide 1 supports the two sets of pipe joints 17 to move to the position of the traction machine, the slide drives the pipe joints 17 to press against the outside of the two sets of extension pipes 20 inside the traction machine 14. By moving to the end of the track, the pipe joints 17 are inserted into the insertion pipe 20b outside the quick-release seat 20a. At the same time, the torsion spring 20e supports the clamping arm 20c to clamp and lock it to the outside of the pipe joints 17, thereby realizing the quick connection of the two extension pipes 20 to the main water supply pipe 16 and the long air pipe 13.

[0094] S4. Then, the water and gas circuits are connected through the two sets of pipe joints 17 in the top drag plate of the slide, and the slide 1 is moved to the required fire extinguishing position along the hanging rail 2. At the same time, the core tube 14b is driven to rotate by the servo motor 14c to loosen the winding and tightening state of the extension tube 20. Thus, the two extension tubes 20 are pulled along the hanging rail 2 by the two sets of pipe joints 17 until the slide 1 is moved to the required fire extinguishing position. Then, the fire extinguishing water is sent by the external water pump along the core tube 14b, extension tube 20, pipe joint 17, water supply main 16, water supply branch 11, lower reel 8 and conduit 18 into the water distribution pipe 602 on the bottom side of the auxiliary plate 6. The fire extinguishing water is sprayed downward through the spray hole 602a on the bottom side of the water distribution pipe 602.

[0095] S5. When burning materials on the ground at the fire scene obstruct people's escape, follow the above steps to open the water and air channels, and separate the auxiliary plate 6 and the pressure plate 5 vertically. At the same time, spray water downwards through the bottom nozzle 602a of the rectangular water distribution pipe 602 on the bottom side of the auxiliary plate 6, forming a four-sided water curtain between the auxiliary plate 6 and the pressure plate 5. The four-sided water curtain, the top auxiliary plate 6, and the bottom pressure plate 5 form a rescue space. The pressure plate 5 in its lowered state serves as a rescue stepping platform. People stand on the surface of the pressure plate 5 and use the suspended rail to walk across the fire ground. At the same time, air is supplied to the pipe joint 17, the long air pipe 13, the lower roller 8, and the short air pipe 15 through an extension pipe 20 connected to the air pump. Clean air is then introduced into the rescue space through the diffuser connected to the short air pipe 15 to maintain a positive pressure state in the rescue space and provide breathing support to the people being rescued in the burning area.
