Description

Technical Field

[0001] This utility model relates to the field of emergency rescue equipment technology for emergency situations such as high-rise building fires, geological disasters, and ship accidents, and in particular to a rapidly deployable dual-channel flexible evacuation and rescue system based on a hydraulic lifting vehicle platform. Background Technology

[0002] In the event of fires, explosions, or other emergencies in high-rise buildings, large ships, or similar locations, the rapid evacuation of trapped personnel is the primary task of rescue operations. Traditional evacuation methods, such as staircases, fire ladders, descent devices, and air cushions, all have significant limitations. Staircases are easily blocked by smoke and fire during a fire, and people descend slowly, which can easily lead to stampedes in a state of panic. They are not suitable for the elderly, weak, sick and disabled. Fire ladder trucks: While capable of reaching higher floors, their rescue method typically involves transporting people one by one, resulting in low rescue efficiency and an inability to meet the needs of rapid evacuation of large crowds. Furthermore, their operational range is significantly limited by available space. Individual descenders: These require trapped individuals to have certain operational skills and psychological qualities. They must be securely installed before use and can only be used by one person at a time. They are also inefficient and unsuitable for children, the elderly, and the injured.

[0003] Rescue air cushions have risks such as limited jumping height, the need for precise jumping, the ability to support only one person at a time, and the risk of injury due to improper positioning, making them suitable for specific scenarios.

[0004] In summary, existing technologies present a significant contradiction between rescue efficiency and universal safety. Therefore, there is an urgent need in this field for an integrated rescue equipment that can quickly reach the scene, be flexibly deployed, rapidly establish multiple uninterrupted and continuous personnel transport escape routes, and adapt to different scene environments while ensuring a comfortable and safe escape process. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides the following technical solution: The core of the hydraulic lifting dual-channel mobile flexible evacuation and rescue system lies in the following technical solution: based on the chassis of a hydraulic lifting vehicle, a set of dual-channel telescopic flexible cloth bag assembly is carried by the modified hydraulic lifting telescopic arm, and the two are deeply linked by an innovative steel wire rope follow-up tensioning system, integrating them into a highly efficient rescue system.

[0006] Specifically, A hydraulic lifting dual-channel mobile flexible evacuation and rescue system, comprising: Hydraulic lifting vehicle chassis; A hydraulic lifting telescopic boom is installed on the vehicle chassis; The dual-channel telescopic flexible fabric bag assembly is supported by the hydraulic lifting telescopic arm; The dual-channel stretchable flexible bag assembly includes... An imported rigid frame is located at the distal end of the telescopic arm; An outlet rigid frame is disposed at the end of the telescopic boom; Two flexible bags are connected between the inlet rigid frame and the outlet rigid frame and are symmetrically arranged on the left and right sides of the hydraulic lifting telescopic arm. Each flexible bag is equipped with three self-locking motor assemblies and three steel wire ropes. The three self-locking motor assemblies are evenly arranged at 90° intervals on the semicircle of the inlet rigid frame or the outlet rigid frame. One end of each steel wire rope is wound around a self-locking motor assembly, and the other end is fixed to the rigid frame at the other end of the channel and passes through several suspension rings provided on the flexible bag. The self-locking motor assembly is hydraulically linked or controlled to the extension and retraction of the hydraulic lifting telescopic arm, so that the wire rope is pulled up and released synchronously with the extension and retraction of the telescopic arm, and the flexible bag is always kept in a taut, tilted, and drooping state.

[0007] Furthermore, the imported rigid frame and the exported rigid frame are steel wire rope spatial orientation retainers that are approximately the shape of an eyeglass frame.

[0008] Furthermore, the imported rigid frame is also connected to an escape passage entrance docking and transition platform.

[0009] Furthermore, a channel exit landing buffer pad is provided below the rigid frame of the exit.

[0010] Furthermore, the two ends of the flexible bag are seamlessly connected and fixed to the inlet rigid frame and the outlet rigid frame, respectively.

[0011] Furthermore, the outer layer of the flexible bag is additionally covered with a secondary safety protection wire mesh.

[0012] Furthermore, the system also integrates one or more IoT functional modules from lighting, image transmission, digital positioning communication, and broadcasting systems.

[0013] Furthermore, the chassis of the hydraulic lifting vehicle is either an internal combustion engine driven chassis or an electric drive chassis.

[0014] Furthermore, the chassis of the hydraulic lifting vehicle is equipped with a blower, which is connected to a dual-channel retractable flexible bag assembly via a blower duct.

[0015] Furthermore, a storage unit is also provided at the end of the telescopic arm. The storage unit has a storage space inside that can accommodate the flexible cloth bag, which can be stored in whole or in part. During rescue work, the flexible cloth bag is pulled out from the storage unit in sync with the extension of the telescopic arm, and the pulled-out flexible cloth bag can always be kept taut.

[0016] Compared with the prior art, the present invention has the following significant advantages: Doubled rescue efficiency: Adopting a unique left-right symmetrical dual-channel design, it allows two escapees to slide down in parallel at the same time, just like setting up two parallel "lifelines", which greatly improves the rescue throughput per unit time, and is especially suitable for large-scale rapid evacuation of high-rise densely populated places. High safety and versatility: The seamless connection of the passageway avoids secondary risks during personnel transfer; the flexible bag and cushioning pad design provides a soft and smooth sliding experience and landing cushioning, effectively preventing abrasions and bruises; simple operation, no training required, and the sliding method is suitable for people of almost all ages and physical conditions. Rapid deployment and high degree of automation: The innovative "follow-up tensioning" system enables the deployment and retraction of the passage to be completed automatically and synchronously with the movement of the telescopic arm, eliminating tedious manual preparation and debugging work, and realizing "the passage is formed as soon as the arm arrives", thus saving valuable time for rescue. Highly mobile and adaptable: Based on a mature hydraulic aerial work platform, it has excellent mobility, passability and working range; the boom's luffing and rotation functions enable it to flexibly cope with various complex on-site environments and achieve precise docking. The dual-channel flexible evacuation passage adopts a closed design. Its flexible bags are made of fabric with high load-bearing capacity, wear resistance, cut resistance, fire resistance, heat insulation and high temperature resistance, which ensures the safety of personnel during the sliding process in the passage and avoids the influence of the surrounding environment (high temperature, toxic and harmful fumes, etc.).

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] The hydraulic lifting dual-channel mobile flexible evacuation and rescue system provided by this utility model is based on the deep integration of the dual-channel flexible escape system with mature hydraulic aerial ladder truck technology, which forms an efficient and reliable mobile rescue platform.

[0023] See Figure 1 This utility model includes a hydraulic lifting vehicle platform 1, a hydraulic support 2, a hydraulic lift vehicle telescopic arm 9, and a dual-channel telescopic flexible cloth bag assembly. The hydraulic lifting vehicle platform 1 serves as the mobile and power foundation for the entire equipment and can be an internal combustion engine-driven or electric drive chassis. After the vehicle is in place, the hydraulic support 2 is deployed to ensure stability during operation.

[0024] The hydraulic lift vehicle telescopic boom 9 is installed on the vehicle platform 1 and has rotation, luffing and telescopic functions, used to locate the entrance and exit of the escape passage in three-dimensional space; The dual-channel retractable flexible bag assembly is the core unit for carrying out rescue missions. It adopts a symmetrical dual-channel design (as shown in A-channel 4 and B-channel 7 in the figure), allowing for simultaneous parallel evacuation of personnel and significantly improving rescue efficiency. Each independent channel consists of the following parts: The rigid frame system includes an inlet rigid frame 11 (or upper retainer) located at the farthest end of the telescopic boom 9 and an outlet rigid frame 6 (or lower retainer) located at the first-stage main rod end of the telescopic boom 9. Both rigid frames adopt an approximately "eye-shaped" structure as the fixing foundation for the wire rope 10. Their main function is to maintain the spatial relative orientation of the wire rope 10, thereby forming a stable conical or cylindrical channel space.

[0025] Furthermore, the upper retainer 11 is connected to the escape passage entrance docking transition platform 12, which facilitates the rapid entry of trapped personnel; the lower retainer 6 is correspondingly arranged with a bag passage exit landing buffer pad (3, 5) to provide a soft landing experience for escapees.

[0026] The flexible passageway body comprises two flexible fabric bags 13 that can be compressed and stretched along the passageway axis. Each flexible fabric bag 13 is seamlessly connected at both ends to the corresponding frames of the inlet rigid frame 11 and the outlet rigid frame 6, ensuring a seamless flow and unobstructed movement of personnel. To further enhance safety, a secondary safety wire mesh (not shown in the figure) can be independently added to the outer layer of the flexible fabric bags 13, providing double protection.

[0027] Preferably, a buffer protective layer 63 is also fixedly provided inside the rigid frame 61 to prevent personnel from being damaged by collision with the frame 61 when entering or exiting the flexible cloth bag 13.

[0028] The wire rope follow-up tensioning system is key to achieving synchronous extension and retraction of the channel with the telescopic arm. Each flexible bag 13 is equipped with three wire ropes 10 and three corresponding self-locking motor assemblies 62 (the self-locking motor can be a hydraulic motor or an electric motor). Figure 2 As shown, the three sets of self-locking motor assemblies 62 are evenly distributed at 90° intervals on the semicircle of one of the corresponding frames of the upper retainer 11 or the lower retainer 6. Figure 2 (Taking the following retainer 6 as an example), one end of each wire rope 10 is fixed to the retainer at one end of the channel, and the other end passes through the suspension rings (20, 21, 22) on the flexible cloth bag 13 and is wound around the self-locking motor assembly 62 at the other end.

[0029] Furthermore, the chassis of the hydraulic lifting vehicle can also be equipped with a blower, which is connected to a dual-channel retractable flexible bag assembly via an air supply pipeline, providing stable and continuous fresh air to the flexible evacuation channel and ensuring the safety and comfort of personnel during the descent.

[0030] Workflow: After the equipment arrives at the rescue site, the operator first stabilizes the vehicle using the hydraulic support 2, then operates the telescopic boom 9 to rotate and extend / retract. As the telescopic boom 9 extends outward under the drive of the hydraulic system, the control system simultaneously instructs the self-locking motor assembly to release the steel wire rope 10. The flexible cloth bag 13 extends outward synchronously under the guidance of gravity and the steel wire rope until the rigid frames of the inlet and outlet reach the docking point on the ground or building. During this process, the self-locking motor assembly always provides a certain preload to the steel wire rope, keeping the steel wire rope 10 and the cloth bag 13 in a taut, inclined state, forming a smooth downward curve. When the telescopic boom 9 stops moving, the self-locking motor assembly locks itself synchronously, completely fixing the channel shape. The entrance transition platform 12 is precisely aligned with the exit of the building 14 to be rescued. Trapped personnel can then sit in the channel entrance in sequence and slide smoothly down the flexible cloth bag 13 under the action of gravity, finally landing safely through the exit buffer pad (3, 5). The entire process is continuous, efficient, and safe. After the rescue mission is completed, the telescopic arm 9 is retracted, the self-locking motor assembly synchronously winches and retracts the wire rope 10, and the flexible cloth bag 13 also shrinks and folds synchronously, returning to a compact storage state.

[0031] Furthermore, this equipment can also integrate IoT modules such as a lighting system (to provide illumination for nighttime rescue), an image transmission system (to transmit the situation inside the passage and at the exit back to the control panel in real time), a digital positioning and communication system (for vehicle dispatching and positioning), and a personalized broadcasting system (for comforting and guiding escaping personnel) according to different vehicle models and needs, thereby further improving the intelligence level and safety of rescue operations.

[0032] Furthermore, this utility model can also be equipped with a structure for storing flexible fabric bags, for example... Figure 4 As shown, a storage unit 15 is provided at the tail end of the telescopic arm 9. The storage unit contains a storage space for the flexible cloth bag 13. When not in operation, the flexible cloth bag 13 can be fully or mostly stored within it, increasing its lifespan. During rescue operations, the flexible cloth bag 13 is pulled out of the storage unit synchronously with the extension of the telescopic arm 9, and the pulled-out flexible cloth bag remains taut at all times. Specific structural forms that achieve the above functions are existing technologies. For example, the storage unit 15 may be equipped with a traction rope drive structure to control the extension or retraction of the flexible cloth bag 13 into the storage unit 15; these will not be elaborated upon here.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
