[0033] Suspended monorail trains are usually composed of multiple carriages. They are an effective supplement to urban rail and urban rail transit and also serve as city sightseeing trains. However, suspended monorail trains may encounter some emergencies during operation, such as being unable to move or a fire in a carriage. At this time, rescue devices are needed to rescue the suspended monorail train. The current rescue device is usually a movable platform, which moves to the location of the accident train and carries out rescue. However, the length of suspended monorail trains can vary. For suspended monorail trains that are too long, the movable platform will have carriages that are difficult to take into account. Passengers in these carriages can only enter the movable platform through other carriages, which greatly reduces the rescue efficiency. Therefore, it is difficult for existing rescue devices to maintain consistent and good rescue efficiency for suspended monorail trains of different lengths.

[0034] To this end, an embodiment of the present invention provides a rescue device 1000, specifically referring to the accompanying drawings of the specification. Figures 1 to 4 shown.

[0035] Reference Figure 1 and Figure 2 As shown, a rescue device 1000 according to an embodiment of the present invention is used to rescue a suspended monorail train 2000. The suspended monorail train 2000 is provided with a connecting portion 2100, and the connecting portion 2100 is slidably connected to the track beam 3000. Figure 2 As shown, it should be noted that the track beam 3000 is provided with a train track 3100, the train track 3100 is arranged along the extension direction of the track beam 3000, and the connecting part 2100 is slidably connected to the train track 3100. Obviously, when the connecting part 2100 slides, it will drive the suspended monorail train 2000 to move along the track beam 3000, thereby realizing the transportation function of the suspended monorail train 2000.

[0036] Reference Figure 1 and Figure 3 As shown, the rescue device 1000 includes a plurality of mobile components 100, a plurality of frames 200 and a flexible shell. The plurality of mobile components 100 are sequentially slidably connected to the track beam 3000 along the extension direction of the track beam 3000. Figure 2 As shown, it should be noted that the track beam 3000 is provided with a rescue track 3200, and the rescue track 3200 is arranged along the extension direction of the track beam 3000, and the mobile component 100 is slidably connected to the rescue track 3200. In addition, the multiple frames 200 are fixedly connected to the multiple mobile components 100 in a one-to-one correspondence, so that the frames 200 follow the corresponding mobile components 100 to slide along the track beam 3000. In one embodiment, the multiple frames 200 and the multiple mobile components 100 correspond to each other and are connected by welding. Figure 2As shown, the frame 200 is provided with a notch 210 for avoiding the connection part 2100, so as to avoid the frame 200 from colliding with the connection part 2100 when moving toward the suspended monorail train 2000 where an accident or failure occurs. It should be noted that the shape and size of the notch 210 can be set according to the specific situation and are not specifically limited here. It should be noted that the frame 200 is made of alloy material, such as titanium alloy, aluminum alloy, etc. It is understandable that the frame 200 made of titanium alloy or aluminum alloy is lighter in weight, moves faster, and does not require excessive driving force.

[0037] Reference Figure 1 and Figure 2 As shown, it should be noted that the flexible shell is connected to the peripheral side of the multiple frames 200 to define a rescue channel 310. Among them, the rescue channel 310 can be wrapped around the peripheral side of the suspended monorail train 2000. It should be noted that the flexible shell will not cover the gap 210 of the frame 200, so that the rescue channel 310 can be smoothly wrapped around the peripheral side of the suspended monorail train 2000. It can be understood that when rescuing suspended monorail trains 2000 of different lengths, the multiple frames 200 can be controlled to move closer or farther from each other through the movement of multiple mobile components 100, thereby changing the length of the rescue channel 310 for suspended monorail trains 2000 of different lengths to maintain consistent and good rescue efficiency.

[0038] It is understandable that the rescue device 1000 can be used for personnel transfer between two vehicles, that is, the rescue device 1000 can transfer passengers on the suspended monorail train 2000 that has an accident to the suspended monorail train 2000 that can operate normally. The specific transfer process is: the suspended monorail train 2000 that can operate normally moves to one end of the suspended monorail train 2000 that has an accident, and the multiple moving components 100 move so that the rescue channel 310 wraps around the two suspended monorail trains 2000. At this time, the passengers on the suspended monorail train 2000 that has an accident can enter the rescue channel 310, walk along the rescue channel 310 to the suspended monorail train 2000 that can operate normally, and enter the suspended monorail train 2000 that can operate normally, thereby completing the personnel transfer between the two vehicles.

[0039] It is understood that the flexible shell is flexible and will not hinder the change of the length of the rescue channel 310. In one embodiment, the flexible shell is made of textile fabric. In one embodiment, the flexible shell made of textile fabric is coated with a fire-retardant coating, so that the flexible shell has a certain fire-proof ability. It is understood that at this time, the rescue device 1000 can be used as a fire-fighting tool. If the suspended monorail train 2000 catches fire, the rescue channel 310 can wrap it, thereby preventing the fire from spreading and preventing the burning residue from falling. In addition, it is understood that since the suspended monorail train 2000 relies on the train track 3100 to run, the rescue device 1000 relies on the rescue track 3200 to run, so the rescue device 1000 will not affect the operation of the suspended monorail train 2000. In addition, there will be some curved sections in the track beam 3000. When the rescue device 1000 needs to turn, the multiple frames 200 can also be controlled to move closer or farther from each other through the movement of multiple moving components 100, thereby improving the turning ability of the rescue device 1000. That is to say, among the multiple frames 200 , the frames 200 located in the curved section of the track beam 3000 are farther apart from each other.

[0040] Reference Figure 2 As shown, in a rescue device 1000 according to an embodiment of the present invention, two rescue tracks 3200 are provided, and the two rescue tracks 3200 are respectively located on both sides of the train track 3100. In addition, the moving assembly 100 includes two moving parts 110, and the two moving parts 110 are respectively fixedly connected to both sides of the notch 210, for example, the two moving parts 110 are respectively welded to both sides of the notch 210. The two moving parts 110 are respectively slidably connected to the two rescue tracks 3200. It can be understood that through the above arrangement, the stability of the movement of the rescue device 1000 can be improved. Continue to refer to Figure 2 As shown, it should be noted that the moving member 110 includes a first driving member 111 and a roller 112. The roller 112 is slidably arranged on the rescue track 3200, and the first driving member 111 is fixedly connected to the corresponding frame 200 and is drivingly connected to the roller 112. It should be noted that the first driving member 111 drives the roller 112 to rotate so that the roller 112 drives the corresponding frame 200 to move along the track beam 3000. In one embodiment, the roller 112 is provided in plurality, for example, two, four, six, etc. In one embodiment, the first driving member 111 is a motor.

[0041] Reference Figure 3 and Figure 4As shown, a rescue device 1000 of an embodiment of the present invention further includes a telescopic assembly 400. It should be noted that the telescopic assembly 400 includes a plurality of first telescopic members 410, and a first telescopic member 410 is provided between each two adjacent frames 200. In one embodiment, a first telescopic member 410 is provided between each two adjacent frames 200. It should be noted that the first telescopic member 410 includes a first connecting rod 411 and a second connecting rod 412. Among them, one end of the first connecting rod 411 and one end of the second connecting rod 412 are respectively rotatably connected to the two adjacent frames 200, and the other end of the first connecting rod 411 and the other end of the second connecting rod 412 are connected by a ball joint. It can be understood that the above scheme can improve the overall rigidity of the rescue device 1000, and due to the presence of the ball joint, the telescopic assembly 400 will not affect the change in the length of the rescue channel 310, nor will it affect the cornering ability of the rescue device 1000.

[0042] Reference Figure 3 and Figure 4 As shown, in one embodiment, the telescopic assembly 400 also includes a plurality of second telescopic members 420, and a second telescopic member 420 is provided between each two adjacent frames 200. In one embodiment, a second telescopic member 420 is provided between each two adjacent frames 200. It should be noted that the second telescopic member 420 includes a third connecting rod 421 and a fourth connecting rod 422. Among them, one end of the third connecting rod 421 and one end of the fourth connecting rod 422 are respectively rotatably connected to the two adjacent frames 200, and the other end of the third connecting rod 421 and the other end of the fourth connecting rod 422 are connected by a ball joint. It should also be noted that the first connecting rod 411, the second connecting rod 412, the third connecting rod 421 and the fourth connecting rod 422 define a prismatic hole. It can be understood that by adopting the above scheme, the prismatic shape has higher stability, which can further improve the overall rigidity of the rescue device 1000, and due to the presence of the ball joint, the telescopic assembly 400 will not affect the change in the length of the rescue channel 310, nor will it affect the cornering ability of the rescue device 1000. Refer to Figure 3 and Figure 4 As shown, in one embodiment, two telescopic assemblies 400 are provided, and the two telescopic assemblies 400 are respectively installed on two opposite sides of the plurality of frames 200 , thereby further improving the rigidity of the rescue device 1000 .

[0043] A rescue device 1000 according to an embodiment of the present invention further comprises a plurality of safety belts, which are connected to the plurality of frames 200 in a one-to-one correspondence, and the plurality of safety belts are all located in the rescue passage 310. It can be understood that, through the above arrangement, the rescue device 1000 has the ability to transport passengers. After the rescue passage 310 wraps the suspended monorail train 2000, the passenger comes out of the suspended monorail train 2000 and enters the rescue passage 310. After the passenger fastens the safety belt in the rescue passage 310, the rescue device 1000 can transport the passenger away and keep the passenger away from danger.

[0044] A rescue device 1000 according to an embodiment of the present invention further comprises a first docking mechanism, and the first docking mechanism is connected to any one of the frames 200. In addition, the suspended monorail train 2000 is provided with a second docking mechanism, and the first docking mechanism can be fixedly connected to the second docking mechanism so that the suspended monorail train 2000 and the frame 200 move synchronously. It can be understood that, by adopting the above scheme, when the suspended monorail train 2000 cannot move autonomously, the rescue device 1000 can move toward it and allow the rescue channel 310 to wrap it. Afterwards, the first docking mechanism is fixedly connected to the second docking mechanism, and the rescue device 1000 drives the suspended monorail train 2000 to move by its own movement, thereby completing the rescue. In one embodiment, the first docking mechanism and the second docking mechanism are both electromagnetic docking mechanisms. In another embodiment, the first docking mechanism and the second docking mechanism are both hook and cable docking mechanisms.

[0045] A rescue device 1000 according to an embodiment of the present invention further includes a fire extinguishing device, which is mounted on the frame 200 and located in the rescue passage 310. It should be noted that the fire extinguishing device includes a storage tank, an airbag, a second driving member and a controller. The storage tank has a storage cavity for storing fire extinguishing substances, and one end of the storage tank is provided with a through hole connected to the storage cavity, and the airbag is installed on the storage tank and connected to the through hole. In addition, a movable end plate is provided at the other end of the storage tank, and the second driving member can drive the end plate to move to change the volume of the storage cavity. The controller is electrically connected to the second driving member. It is understandable that if the suspended monorail train 2000 catches fire, after the passengers are evacuated, the second driving member can be controlled by the controller to work, and the second driving member drives the end plate to move, so that the volume of the storage cavity becomes smaller, squeezes the fire extinguishing substances in the storage cavity, and the fire extinguishing substances are gradually squeezed into the airbag, and the airbag gradually expands. After expanding to a certain extent, the airbag will explode and spray the fire extinguishing substances to extinguish the fire. It should be noted that the second driving member is a cylinder. In one embodiment, the fire extinguishing substance is carbon dioxide; in another embodiment, the fire extinguishing substance is a foam fire extinguishing agent.

[0046] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features therein can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
