Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and in particular to a high-rise building fire-fighting suspended platform device. Background Technology

[0002] With the acceleration of urbanization, high-rise buildings are becoming increasingly common in modern cities. However, high-rise building fires are characterized by rapid fire spread, difficult evacuation, and limited rescue capabilities, seriously threatening the lives and property of the people.

[0003] Currently, my country's "Code for Fire Protection Design of Buildings" has established relevant requirements for fire safety in high-rise buildings: Residential buildings with a height exceeding 100 meters must be equipped with automatic fire extinguishing systems and automatic fire alarm systems; residential buildings with a height between 54 meters and 100 meters are required to install automatic fire alarm systems in public areas, and it is recommended to install fire detectors in individual units; for high-rise residential buildings with a height of less than 54 meters, it is recommended to install automatic fire alarm systems in public areas, and these systems must be installed if linkage control with fire protection facilities is required. Furthermore, all high-rise residential buildings should be equipped with fire alarm devices or emergency broadcast systems with voice functionality in their public areas.

[0004] However, current regulations have significant shortcomings: for high-rise buildings, especially residential buildings, with a height between 25 and 100 meters, the installation of automatic fire suppression systems is not mandatory. This regulatory gap makes it difficult to effectively control fires in such buildings, greatly increasing the risk of significant casualties and property damage. Traditional fire rescue equipment, such as fire truck ladders and aerial work platforms, is often limited by multiple factors when dealing with such high-rise fires: firstly, the working height of the equipment itself is limited; secondly, urban traffic congestion affects the arrival of rescue vehicles at the scene; and thirdly, the surrounding environment of the building restricts the operating space. These factors combined make it difficult for traditional fire rescue methods to meet the growing fire protection needs of high-rise buildings.

[0005] Especially during actual rescue operations, the inability of fire trucks to reach the fire scene in a timely manner, or the obstruction of parking spaces, green areas, and other facilities around the building preventing effective operations, significantly delays the optimal time for fire suppression. These problems have been fully demonstrated in major fire accidents in many Chinese cities, highlighting the urgency of developing new high-rise building fire rescue equipment. Utility Model Content

Detailed Implementation

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] The high-rise fire-fighting suspended platform device described in this embodiment aims to overcome the limitations of traditional fire-fighting equipment in terms of operating height and space. By designing a telescopic mechanism at the top of high-rise buildings, it achieves stable lifting and lowering of the suspended platform, accurately reaching the predetermined floor, thereby efficiently carrying out fire-fighting and rescue operations. Figures 1 to 4 As shown, the device includes a suspended platform body 10, fire-fighting equipment 20, a drive mechanism 30, and a telescopic mechanism 40.

[0027] The suspended platform 10 serves as the support platform for the fire-fighting equipment 20. In this embodiment, the suspended platform 10 is made of high-strength lightweight aluminum alloy material to ensure that it meets the load-bearing requirements while minimizing the overall weight and reducing the burden on the drive mechanism 30. The fire-fighting equipment 20 can be a device that sprays various extinguishing agents such as water, foam, and dry powder through high-pressure nozzles to meet the fire-fighting needs in different scenarios.

[0028] A drive mechanism 30, located at the top of the building, provides power to the telescopic mechanism 40. The upper end of the telescopic mechanism 40 is connected to the drive mechanism 30, and the lower end is connected to the suspended platform body 10. In this embodiment, the telescopic mechanism 40 includes at least two scissor-type guide mechanisms 41 arranged parallel in the vertical direction, with at least one rigid chain 42 between adjacent scissor-type guide mechanisms 41. Specifically, the scissor-type guide mechanism 41 consists of multiple sets of hinged scissor arms, forming a scissor-like structure. Its main function is to provide guidance and support for the suspended platform body 10, ensuring that it does not sway or tilt during lifting and lowering. The rigid chain 42 is a special chain structure that exhibits rigidity when extended, capable of withstanding greater pressure and less prone to bending or breaking, thereby ensuring the safe lifting and lowering of the suspended platform.

[0029] In this embodiment, the power output end of the drive mechanism 30 is connected to the rigid chain 42 for driving and adjusting the extension length of the rigid chain 42, thereby driving the suspended platform body 10 to rise and fall vertically to the target floor. When the drive mechanism 30 is activated, it drives the rigid chain 42 to extend downward, thereby driving the suspended platform body 10 to descend vertically. At the same time, the scissor-type guide mechanism 41 also extends, providing stable support and guidance for the suspended platform body 10. Conversely, when the drive mechanism 30 rotates in the opposite direction, the rigid chain 42 retracts upward, thereby driving the suspended platform body 10 to rise and return to its original position. Through the above method, the suspended platform body 10 can be smoothly raised and lowered on the exterior of a high-rise building, enabling it to reach the target floor.

[0030] Specifically, such as Figure 1 , Figure 2As shown, the drive mechanism 30 includes a boom 31 and a drive motor 32; the boom 31 is provided with two chain boxes 33 extending along its length and arranged in parallel, and the drive motor 32 is located at the far end of the boom 31 and between the two chain boxes 33; the drive motor 32 is connected to the sprocket in the chain box 33 through a dual-shaft transmission mechanism, and the rigid chain 42 is provided as two chains and respectively cooperates with the corresponding chain box 33, with the top end of each rigid chain 42 extending into the corresponding chain box 33 and meshing with the sprocket.

[0031] In practice, a rotatable and translatable track-moving mechanism 50 is installed on the top of the building. The boom 31 is securely fixed to the track-moving mechanism 50 with high-strength bolts to ensure sufficient load-bearing capacity and stability. The boom 31 typically extends beyond the edge of the building and needs to cover most of the building's facade. The drive motor 32 is a high-performance servo motor with precise speed regulation and positioning capabilities, providing smooth and reliable power output to the telescopic mechanism 40.

[0032] In practical applications, such as Figure 3 As shown, when a fire occurs in a high-rise building, the control system will automatically activate the track moving mechanism 50 after receiving the fire alarm signal, or manually control the boom 31 to move precisely to the position corresponding to the fire floor. Then, according to the height of the fire floor, the drive motor 32 will precisely adjust the extension length of the telescopic mechanism 40 so that the height of the basket body 10 is accurately aligned with the window of the target floor. Subsequently, the fire-fighting equipment 20 on the basket body 10 will spray fire extinguishing agent into the room, thereby achieving rapid and efficient fire suppression of high-rise fires and avoiding situations where operations cannot be effectively carried out due to obstruction by parking, greening and other facilities around the building.

[0033] In some embodiments, such as Figure 1 , Figure 4 As shown, the scissor-type guide mechanism 41 includes multiple scissor units that are hinged sequentially. Each scissor unit includes two scissor arms 411 that are arranged crosswise and hinged together by a hinge axis. In this embodiment, the scissor arms 411 are typically made of high-strength alloy steel to ensure sufficient load-bearing capacity and bending stiffness. The outer ends of two adjacent hinge axes located on the same horizontal plane are each provided with a first connecting rod 412. The two ends of the two first connecting rods 412 on the same horizontal plane are connected by a second connecting rod 413. The first connecting rods 412, the second connecting rods 413, and the scissor units form a guide space for accommodating the rigid chain 42.

[0034] In this way, the first connecting rod 412 and the second connecting rod 413 together form a stable frame structure. The frame structures, together with the scissor lift unit, form a guide space to accommodate the rigid chain 42. This not only effectively protects the rigid chain 42 from damage by the external environment and extends its service life, but also accurately guides the rigid chain 42 to move along a predetermined trajectory, preventing it from deviating or bending, thereby ensuring the smoothness and accuracy of the lifting and lowering movement of the suspended platform body 10.

[0035] In some embodiments, such as Figure 1 As shown, the distal end of the boom 31 is provided with a support 34, which is positioned opposite to the basket body 10. The support 34 has a guide hole for the rigid chain 42 to pass through. The upper end of the scissor-type guide mechanism 41 is fixedly connected to the support 34, and the lower end is fixedly connected to the basket body 10. Specifically, the guide hole can accurately guide the movement trajectory of the rigid chain 42, avoiding friction or interference with other components. By fixing the upper end of the scissor-type guide mechanism 41 to the support 34 and the lower end to the basket body 10, it is not only convenient to install the scissor-type guide mechanism 41 onto the boom 31, but also to tightly integrate the scissor-type guide mechanism 41 with the basket body 10 to form a whole, thereby effectively distributing the load and improving the strength and rigidity of the overall structure.

[0036] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 As shown, the fire-fighting equipment 20 includes a window-breaking device 21 and a fire-extinguishing device 22. The window-breaking device 21 is used to break a window when the suspended platform body 10 reaches the target floor, and the fire-extinguishing device 22 is used to spray fire extinguishing agent into the building through the opening formed after the window is broken. The window-breaking device 21 is configured to automatically break the window immediately after the suspended platform body 10 safely and stably reaches the target floor, creating favorable conditions for subsequent fire-fighting operations. The fire-extinguishing device 22 is designed to accurately spray fire extinguishing agent into the building through the opening formed after the window is broken, so as to quickly control and extinguish the fire source. In specific implementations, the window-breaking device 21 can be selected from various types, such as impact type, cutting type, and blasting type, and can be flexibly configured according to actual needs. The fire-extinguishing device 22 can be a high-pressure water gun, foam sprayer, or dry powder sprayer, etc., to adapt to the fire-fighting needs of different types of fires.

[0037] In one specific embodiment, such as Figure 1 , Figure 4As shown, the window breaking device 21 includes a robotic arm 211 and a striking pin 212 disposed at the end of the robotic arm 211, the striking pin 212 being provided with a conical needle tip; the fire extinguishing device 22 is a high-pressure nozzle disposed at the end of the robotic arm 211.

[0038] In practice, a water tank 222 is installed on the track moving mechanism 50, and the high-pressure nozzle, i.e. the fire extinguishing device 22, is connected to the water tank through a water supply pipe to spray fire water at high pressure to a greater distance and cover a larger area, thereby effectively controlling the spread of fire; while the robotic arm 211 preferably adopts a six-degree-of-freedom design, which has high flexibility and motion precision, and can accurately control the position and attitude of the firing pin 212, thereby achieving precise window breaking of different types and positions of windows. Furthermore, in this embodiment, to ensure the water supply needs of the high-pressure nozzles, a water tank 222 is installed on the track moving mechanism 50. The high-pressure nozzles, i.e., the fire extinguishing devices 22, are connected to the water tank 222 via a water supply pipe. To avoid potential interference between the water supply pipe and other components of the fire-fighting scaffold device, a hose reel 221 is installed on the water tank 222. The hose reel 221 can adaptively reel in and release the water supply pipe according to the lifting and lowering of the scaffold body 10, thereby effectively avoiding interference between the water supply pipe and other components and ensuring the smooth and reliable operation of the entire fire-fighting scaffold device.

[0039] In some embodiments, such as Figure 4 As shown, the suspended platform body 10 is equipped with a pneumatic suction cup 11. The pneumatic suction cup 11 is used to extend and adhere to the exterior wall of the building or the glass to be broken when the suspended platform body 10 reaches the target floor. In this embodiment, the function of the pneumatic suction cup 11 is to automatically or manually extend when the suspended platform body 10 reaches the target floor and firmly adhere to the exterior wall surface of the building or the glass to be broken, thereby forming a stable connection. This effectively reduces the swaying of the suspended platform at high altitudes caused by wind and other factors, thereby reducing the reaction force when breaking the window. This allows the robotic arm 211 to more easily control the window breaking device 21, improving window breaking efficiency and shortening rescue time.

[0040] In some embodiments, the distance between the boom 31 and the top of the building is greater than the sum of the minimum working length of the telescopic mechanism 40 and the height of the suspended basket body 10. Thus, in non-fire conditions, the boom 31 is rotated via the track moving mechanism 50, allowing the retracted telescopic mechanism 40 and the suspended basket body 10 to be stored together on the top of the building, concealing the suspended basket body 10. This significantly reduces the risk of damage from falling objects and effectively prevents strong winds from affecting the suspended basket body 10.

[0041] The high-rise fire-fighting suspended platform device provided in this embodiment, by installing a drive mechanism at the top of the building and employing a telescopic mechanism combining a scissor-type guide mechanism and a rigid chain, not only achieves stable and controllable lifting and lowering of the platform body but also overcomes the limitations of traditional fire-fighting equipment in terms of operating height and space. The device is equipped with a window-breaking device and a fire-extinguishing device that can work together to quickly and accurately break the glass in a fire while simultaneously spraying fire extinguishing agents, significantly improving fire-fighting and rescue efficiency. Furthermore, the pneumatic suction cups allow the platform body to be firmly attached to the glass surface before breaking the window, effectively preventing swaying during the window-breaking process and greatly ensuring the safety and reliability of rescue operations.
